The description below has been presented for the purposes of illustration and is not intended to be exhaustive or to be limited to the precise form disclosed. It should be understood that alternative implementations may be used in any combination desired to form additional hybrid implementations of the present disclosure. For example, any of the functionality described with respect to a particular device or component may be performed by another device or component. Furthermore, while specific device characteristics have been described, embodiments of the disclosure may relate to numerous other device characteristics. Further, although embodiments have been described in language specific to structural features and/or methodological acts, it is to be understood that the disclosure is not necessarily limited to the specific features or acts described. Rather, the specific features and acts are disclosed as illustrative forms of implementing the embodiments. The following detailed description refers to the accompanying drawings. The same reference numbers may be used in different drawings to identify the same or similar elements. In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular structures, architectures, interfaces, techniques, etc. in order to provide a thorough understanding of the various aspects of various embodiments. However, it will be apparent to those skilled in the art having the benefit of the present disclosure that the various aspects of the various embodiments may be practiced in other examples that depart from these specific details. In certain instances, descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the various embodiments with unnecessary detail. For the purposes of the present document, the phrases “A or B” and “A/B” mean (A), (B), or (A and B). Embodiments herein address the Medium Access Control (MAC) sublayer in a Fifth Generation (5G) wireless communication system. The MAC layer provides services to upper layers and expects some services from the physical layer (PHY). The physical layer offers transport channels to the MAC layer to support transport services for data transfer over a radio interface, and the MAC layer offers logical channels to an RLC sublayer. The logical channels exist between MAC and PHY whereas transport channels exist between PHY and the radio layer. Therefore, importantly, the MAC layer is the interface between logical channels and PHY transport channels. The MAC Layer provides two main services to upper layers, including data transfer and radio resource allocation. The other functions of 5G New Radio (NR) MAC layer include a mapping between logical and transport channels, downlink and uplink, multiplexing of MAC SDUs onto transport blocks in the uplink, wherein SDUs belong to logical channels and transport blocks belong to transport channels, demultiplexing of MAC SDUs from transport blocks in the downlink, scheduling uplink information reporting, hybrid error correction (HARQ), and uplink logical channel prioritization, New Radio (NR) MAC channel mapping for 5G, and 5G NR logical channels and transport channels. The MAC layer includes logical channels that interact with the physical layer (PHY) transport channels. As is known, packed data scheduling PDSCH, broadcast channel PBCH and packet data control channel PDCCH are used in the downlink as channels, and the packet uplink scheduling PUSCH, packet uplink control channel PUCCH and random access channel RACH are uplink channels. Downlink reference signals include synchronization signals DMRS, PT-RS, CSI-RS, PSS and SSS, and uplink reference signals include DMRS, PTRS and SRS. The 5G NR MAC layer is responsible for different functionalities and many procedures including a random access procedure to obtain an initial uplink grant for a UE and perform synchronization with a network node (gNB). The random access procedure includes initialization, random access resource selection, preamble transmission, random access response reception, contention resolution and the like. The MAC layer procedures are also responsible for different functionalities associated with data transfer. For example, DL-SCH data transfer does everything needed to perform downlink data transfer; UL-SCH data transfer does everything needed to perform uplink data transfer. A scheduling request (SR) is used by UE to transmit a request to a gNB to obtain a UL grant. PCH reception monitors paging messages in a special time period; BCH reception carries basic information regarding the 5G NR cell (e.g. MIB, SFN, etc.), and DRX represents discontinuous reception, which monitors the PDCCH for special patterns in a discontinuous manner. The 5G NR MAC layer procedures further affect transmission and reception. For example, the MAC layer handles activation/deactivation of SCells, activation/deactivation of PDCP duplication, BWP (Bandwidth Part) operation, handling of measurement gaps, handling of MAC CEs, beam failure detection and recovery operations. Another important aspect of the 5G NR MAC layer is related to MAC headers and subheaders. A MAC PDU includes one or more MAC sub-PDUs, and each MAC sub-PDU includes one of the following fields: a MAC subheader with padding, a MAC subheader and a MAC SDU, and a MAC subheader and a MAC control element (CE). Each MAC subheader corresponds to either a MAC SDU, a MAC CE, or padding. The MAC SDUs are of variable sizes. A MAC subheader for 5G includes fields such as LCID, “L”, “F”, and “R”. The LCID field: LCID stands for logical channel identifier, which identifies logical channel instances of corresponding MAC SDU or type of corresponding MAC CE or padding. The values of LCID for DL-SCH and UL-SCH are mentioned in the tables below. There is only one LCID field that exists for one MAC subheader. LCID field generally has 6 bits in size. The L-Field, or "L" indicates length field of corresponding MAC SDU or variable sized MAC CE in units of bytes. One "L-field" exists for one MAC subheader. More number of "L- fields" exist for subheaders corresponding to fixed-sized MAC CEs and padding. The "L-field" size is indicated by F-field, with the L field being 8 or 16 bits typically. The F-field refers to length field size. It is one bit in size. There is one F field per MAC subheader except for subheaders corresponding to fixed-sized MAC CEs and padding. The value 0 in F-field refers to 8 bits of Length field. The value 1 in F-field refers to 16 bits of Length field. The R stands for a reserved bit set to zero. In one or more embodiments of the present disclosure, solutions for MBS are provided that affect the MAC layer. Specifically, one or embodiments relate to subheaders in the 5G NR MAC layer to accommodate point to point (PTP) and point to multicast (PTM) transmissions for NR MBS. Specifically, the solutions relate to two delivery modes, a first delivery mode (mode 1) for high quality of service (QoS) MBS services, requiring UE to receive data in RRC_CONNECTED mode, and a second delivery mode (mode 2) for low QoS MBS services, where UE can also receive data in RRC_INACTIVE/IDLE state. For purposes of background, an RRC is a Radio Resource control plane protocol for radio resource management that is used when UE is connected to a core network, and an RRC connection is a point-to-point bi-directional connection between RRC peer entities in the UE and the characterized by the allocation of Radio Network Temporary Identifiers (RNTl). RNTIs are allocated by a base station and are subsequently stored by both the base station and UE. RNTIs are used to address either an individual UE, a group of UE or all UE. For example, the C-RNTI can be used to address an individual UE, whereas an INT-RNTI can be used to address a group of UEs and the SI-RNTI can be used to address all UE. A UE is addressed by using the RNTI to scramble the CRC bits which are attached to the PDCCH OCI payload, i.e. an RNTI is used to address the UE on the PDCCH. The PDCCH can then be used to provide uplink and downlink resource allocations, power control commands, pre-emption indications, slot format changes and system information update indications. A UE has either zero or one RRC connection. An RRC Inactive/Idle mode is when a UE has no established RRC connection. PTP transmission for NR MBS requires that RRC_CONNECTED UEs, use UE- specific PDCCH with CRC scrambled by UE-specific RNTI (e.g., C-RNTI) to schedule UE- specific PDSCH which is scrambled with the same UE-specific RNTI. In one embodiment, for PTM transmission in a first transmission scheme (transmission scheme 1), RRC_CONNECTED UEs in the same MBS group use group-common PDCCH with CRC scrambled by group-common RNTI to schedule group-common PDSCH which is scrambled with the same group-common RNTI. This scheme can also be called group-common PDCCH based group scheduling scheme. For PTM transmissions in a second transmission scheme (transmission scheme 2), RRC_CONNECTED UEs in the same MBS group, use UE-specific PDCCH with CRC scrambled by UE-specific RNTI (e.g., C-RNTI) to schedule group-common PDSCH which is scrambled with group-common RNTI. The second scheme can also be called UE-specific PDCCH based group scheduling scheme. PTM transmission scheme 2 is mainly considered as the PTM retransmission enhancement. Other embodiments relate to improvements of 5G NR as compared to LTE SC-PTM. For example, some physical layer enhancements in 5G, such as HARQ and SPS, are newly supported in the 5G version of NR MBS for reliability improvement and group scheduling. As for HARQ retransmission, MBS can either use PTM for retransmission or use PTP towards dedicated UE. A single channel PTM evolved for NR 5G. The MAC layer includes a Multicast Traffic Channel (MTCH), and a Single-Cell Multicast Traffic Channel (SC-MTCH) defined to transmit traffic data from the network to the UE using SC-PTM. At the physical layer, SC- PTM allows a single cell to broadcast to a group of users over the Physical Downlink Shared Channel (PDSCH), used by unicast transmission. In one or more embodiments, solutions are presented that address the two delivery modes (delivery mode 1 and delivery mode 2) affecting the NR MBS MAC layer including multiplexing and demultiplexing, discontinuous transmissions, semi-persistent scheduling (SPS) and other procedures in the MAC layer due to group scheduling transmission schemes. Delivery mode 1 is for high QoS MBS services, requiring a UE to receive data in RRC_CONNECTED mode, and delivery mode 2 is for low QoS MBS services, where UE can also receive data in RRC_INACTIVE/IDLE state. In one or more embodiments, a new timer is introduced to 5G that is triggered when there is PTM transmission or a retransmission in delivery mode 1 and delivery mode 2. Specifically, the HARQ related timer is introduced for a DRX for MBS: drx- RetransmissionTimerDLMBS, and drx-HARQ-RTT-TimerDLMBS. For PTM DRX cycles/configurations are configured per MBS service for MTCH, where DRX controls UE’s PDCCH monitoring activity for each MBS service corresponding G-RNTI. For delivery mode 1, the timer drx-RetransmissionTimerDL is triggered after drx- HARQ-RTT-TimerDL if transmission via PTM transmission scheme 1 and retransmission via PTP. For delivery mode 1, the timer drx-RetransmissionTimerDLMBS is triggered after drx- HARQ-RTT-TimerDL if transmission via PTM transmission scheme 1 and retransmission via PTM transmission scheme 2. For delivery mode 1, the timer drx-RetransmissionTimerDLMBS is triggered after drx- HARQ-RTT-TimerDLMBS if transmission and retransmission via PTM transmission scheme 1. For delivery mode 2 the retransmission DRX for MCCH monitors a novel RNTI (e.g. MBS-RNTI) to dynamically schedule NR MBS delivery mode 2 control information. In accordance with one or more embodiments, for SPS, an embodiment presents RNTI (e.g. G-CS-RNTI) configured for scheduled MBS transmission in a downlink (DL). Other embodiments herein relate to multiplexing/demultiplexing. For example, one embodiment enables transmission/retransmission via PTP multiplexed with unicast. Thus, multiple logical channels within the same MBS service can multiplex with each other. Different MBS services cannot multiplex with each other, and PTM transmission/retransmission cannot multiplex with unicast. In one or more embodiments, to support MBS via PTP, if LCID is not needed for MBS service, an embodiment provides an MBS MAC subheader to support the separation of different MBS services. One or more embodiments further address how a PDU may accommodate a MAC layer for both multicast and unicast in the same PDU. Specifically, because NR 5G supports a novel mode of multicast service including unicast and a PTP mode, with the simultaneous transmission of unicast and multicast in the same PDU, embodiments herein support such simultaneous transmission. In one or more embodiments, multiple solutions of DRX, SPS and other MAC functionalities for NR MBS, are provided to suit MBS service requirements for different delivery modes and transmission schemes. Thus, embodiments provide for a base station to configure various options considering various MBS services’ characteristics in power saving, service reliability, and the like. Generally, a radio network temporary identifier (RNTI) is allocated by a base station and subsequently stored by both the base station and UE. The RNTIs are used to address either an individual UE, a group of UE or all UE. For example, the C-RNTI can be used to address an individual UE, whereas an INT-RNTI can be used to address a group of UEs and the SI- RNTI can be used to address all UE. A UE is addressed by using the RNTI to scramble the CRC bits which are attached to the PDCCH OCI payload, e.g., an RNTI is used to address the UE on the PDCCH. In one or more embodiments, the RNTI is altered to accommodate MBS services. The PDCCH is used to provide uplink and downlink resource allocations, power control commands, pre-emption indications, slot format changes and system information update indications. C-RNTI is used as the RNTI value when using point to point (PTP) which is like unicast services and the transmission (both PDCCH and PDSCH), since the MBS traffic is dedicated to a user. When MBS service uses PTM transmission, according to one or more embodiments, each MBS service has its own specific RNTI (G-RNTI). Moreover, PTM delivery mode 2 provides for UE-specific PDCCH with CRC scrambled by C-RNTI. Based on the preexisting (RAN1) common understanding of MBS transmission scheme, there are several possibilities of transmission and hybrid automatic retransmission requests (HARQ) retransmission for NR MBS. The types include (a) transmission in PTP and retransmission in PTP, (b) transmission in PTM with the first scheme, and retransmission with the first scheme, (c) transmission in PTM with the first scheme, and retransmission in PTP, and (d) transmission in PTM with the first scheme and retransmission in PTM with the second scheme. Hereinafter the transmission types are referred to as scheme (a), (b), (c), and (d). Embodiments relate the MAC layer scheduling and more particularly to group scheduling with the DRX, SPS, multiplexing using subheaders and the like. A first embodiment relates to the DRX for the MAC layer in NR MBS. More specifically, using a DRX operation, the MAC entity controls the UE’s PDCCH monitoring activity for certain MBS services that were not available in LTE wireless communication systems. Compared with LTE SC-PTM, one embodiment is directed to improving the reliability of multicast/broadcast service, for example in the uplink feedback. More specifically, HARQ- ACK feedback for RRC_CONNECTED UE is supported in one or more embodiments. Thus, DL MBS traffic HARQ retransmission may be expected by the MAC entity, and a DL HARQ RTT timer and DL retransmission timer for MBS MTCH are introduced for NR MBS. DRX of PTP transmission can be configured similarly as unicast, including drx- onDurationTimer, drx-SlotOffset, drx-InactivityTimer, drx-LongCycleStartOffset, drx- RetransmissionTimerDL, and drx-HARQ-RTT-TimerDL. For PTM transmission, configurations for delivery mode 1 used for RRC_CONNECTED UE receiving high QoS MBS services may be configured via dedicated RRC signaling, including multicast traffic channel configuration (MTCH configurations). Hence, in delivery mode 1, according to an embodiment, DRX is configured per MBS service according to service requirement, e.g. latency, to monitor each MTCH of UE’s interested MBS services. For a certain MBS service, it is possible that a UE can receive PTP and PTM simultaneously. In this case, UE is configured with both PTP/unicast DRX cycle and a PTM DRX cycle. If a base station uses PTM transmission scheme (b) above (PTM delivery mode 1 for transmission and retransmission) as mentioned above, each DRX operation controls UE’s PDCCH monitoring activity for each MBS service corresponding group G-RNTI. The radio resource control (RRC) controls its DRX operation by configuring the timers for each G-RNTI: drx-onDurationTimerMBS, drx-SlotOffsetMBS, drx-InactivityTimerMBS, drx-schedulingPeriiodStartOffsetMBS, drx-RetransmissionTimerDLMBS, drx-HARQ-RTT-TimerDLMBS. In one embodiment, the timers are defined as follows: drx-onDurationTimerMBS: the duration at the beginning of a DRX cycle of a MBS service; drx-SlotOffsetMBS: the delay before starting the drx-onDurationTimerMBS of a MBS service; drx-InactivityTimerMBS: the duration after the PDCCH occasion in which a PDCCH indicates a new MBS transmission for the MAC entity; drx-schedulingPeriodStartOffsetMBS: the SchedulingCycleMBS and drx- StartOffsetMBS which defines the subframe wherein the MBS DRX cycle starts, wherein the value of SchedulingCycleMBS is in milliseconds and drx-StartOffsetMBS is in multiples of 1ms; drx-RetransmissionTimerDLMBS: the maximum duration until a MBS retransmission is received (per MBS service); drx-HARQ-RTT-TimerDLMBS: the minimum duration before a DL assignment for MBS HARQ retransmission is expected by the MAC entity. In one or more embodiments, QoS requirements of different MBS services are different and thus, DRX timer durations may vary among services and be different from unicast DRX. If a base station is implementing scheme (c), (PTM delivery mode 1 for transmission, PTP for retransmission) similar scheme (b), the timers may include drx-onDurationTimerMBS, drx-SlotOffsetMBS, drx-InactivityTimerMBS, drx-schedulingPeriodStartOffsetMBS, which can be used to monitor MBS MTCH transmission via PTM. Since a UE has DRX configurations of both unicast and PTM, unicast DRX configuration drx- RetransmissionTimerDL and drx-HARQ-RTT-TimerDL, are expected in a MAC entity. After a UE sends HARQ feedback for MTCH, it starts unicast DRX timer drx-HARQ-RTT-TimerDL. If a base station is implementing (d) scheme, (PTM deliver mode 1 for transmission, PTM delivery mode 2 for retransmission) MBS transmission/retransmission scenario, PTM DRX cycles/configurations are used to monitor different MBS services MTCH transmission according to its G-RTNI. As for HARQ retransmission, unicast DRX cycles/configurations, timers drx-HARQ- RTT-TimerDL, are used to monitor PDCCH for DL assignment of a MBS retransmission, since it is scrambled with a UE specific RNTI (C-RNTI). However, different from scheme (c), the MBS retransmission packets are expected to be received within timer drx- RetransmissionTimerDLMBS, as group-common PDCSH as used for HARQ retransmission. Delivery mode 2 is similar as LTE SC-PTM, DRX, and is configured separately for MCCH and MTCH. For simplicity of transmission for low QoS MBS services, in delivery mode 2, only transmission scheme (b) (PTM scheme 1 for transmission/retransmission) is considered. In this case, DRX for MTCH is also configured per MBS service, including: drx-onDurationTimerMBS, drx-SlotOffsetMBS, drx-InactivityTimerMBS, drx-schedulingPeriodStartOffsetMBS, drx-RetransmissionTimerDLMBS, drx-HARQ-RTT-TimerDLMBS. Different from delivery mode 1, MCCH is introduced in delivery mode 2 to transmit traffic control information. In one embodiment, a novel RNTI (MBS-RNTI) is introduced to dynamically schedule NR MBS delivery mode 2 control information. According to the number of MCCH configured, DRX is configured per MCCH. DRX configuration for MCCH includes timers drx-onDurationTimerMBS, drx-SlotOffsetMBS, drx-InactivityTimerMBS and drx- schedulingPeriodStartOffsetMBS. One or more embodiments relate to semi persistent scheduling (SPS) for NR MBS. Specifically, LTE SC-PTM, semi persistent scheduling (SPS) is not supported for multicast and broadcast services. However, for NR, SPS group-common Physical Downlink Shared Channel (PDSCH) for MBS is supported for RRC_CONNECTED UEs. It is considered dynamic scheduling and DL SPS are supported for NR MBS. For each MBS service, in an embodiment, a one-to-one mapping between MBS service for SPS and DRX services is provided. For delivery mode 1 in transmission scheme (a) above, similar to unicast transmissions, CS-RNTI is used for DL SPS activation/deactivation/retransmission. If there is no PDCCH, DL SPS is used for MBS transmission. In both transmission schemes (b) and (d) for delivery mode 1, group-common PDSCH scrambled with G-RNTI is used for transmission and retransmission. In one or more embodiments, a novel type of RNTI (e.g. G-CS-RNTI) can be used to indicate configured scheduled MBS transmission. According to the quality requirement of different MBS services, DL SPS is configured per service and uses G-CS-RNTI for activation/deactivation/retransmission. For delivery mode 1 in transmission scheme (c), an embodiment provides for novel G- CS-RNTI may apply for DL SPS activation/deactivation, and novel CS-RNTI advantageously according to an embodiment may be for MBS HARQ retransmission so that the downlink assignment of MBS DL SPS retransmission can be received on the PDCCH for the MAC entity’s CS-RNTI. In unicast SPS, the HARQ process ID may be deferred from CURRENT_slot, numberOfSlotsPerFrame, periodicity, nrofHARQ-Processes and harq-ProcID-Offset. It is possible that MBS DL SPS may be overlapped with unicast DL SPS. According to one or more embodiments, a UE can receive unicast and multicast service(s) simultaneously in the same slot according to its capability. To avoid the initial transmission of MBS DL SPS and unicast DL SPS using the same HARQ process ID when they are configured in the same slot, mbs-nrofHARQ-Processes, mbs-harq-ProcID-Offset and mbs-periodicity are introduced to calculate HARQ process ID of MBS DL SPS. If unicast and MBS DL SPS are overlapped in the same slot, mbs-harq-ProcID-Offset is used to set an offset value for MBS DL SPS. Mixed parameters for transmission mode according to one embodiment for the same UE and DRX allow a switch from MBS DRX and when a retransmitting, a timer will switch to parameters without MBS to be unicast. The following parameters may be configured for MBS DL SPS: g-cs-RNTI: G-CS- RNTI for activation, deactivation, and retransmission; mbs-nrofHARQ-Processes: the number of configured HARQ processes for MBS DL SPS; mbs-harq-ProcID-Offset: Offset of HARQ process for MBS DL SPS; mbs-periodicity: periodicity of configured downlink assignment for MBS DL SPS. For delivery mode 2, MBS DL SPS may be the same as transmission scheme (b) as discussed above. Considering one UE can receive multiple MBS services, multiple DL SPS GC-PDSCH configurations may now be supported. One or more embodiments are directed to a multiplexing MAC layer for NR that advantageously allows multiplexing among logical channels within the same MBS session. More specifically, MBS MAC multiplexing embodiments herein relate to the transmission/retransmission via PTP or PTM. For scenario (a) in MBS transmission/retransmission via PTP is allowed to be multiplexed with unicast, both unicast and MBS share the same space of LCID (eLCID if necessary). Different MBS services (and their corresponding logical channels) are mapped to different logical channels defined by gNB. For transmission schemes (b) and (d) scenarios, considering UE power saving, it is proposed that different MBS sessions/services cannot be multiplexed with each other. 1) If each MBS service only has a single logical channel, in PTM transmission, multiplexing among logical channels is not allowed, an LCID is not needed for MBS PTM; 2) If each MBS service has multiple logical channels, in PTM transmission, multiplexing among logical channels within the same MBS session is allowed. Moreover, since PTM is scrambled with G-RNTI, it cannot be multiplexed with unicast transmission. Multiple logical channels can be multiplexed together, however. For transmission scheme (c), MBS transmission can follow the discussion for schemes (b) and (d). In retransmission via PTP, the MBS TB (transport block) may be scrambled with C-RNTI for retransmission. LCID is needed to differentiate different MBS services via PTP. This retransmission cannot multiplex with unicast. Regarding the LCID value, embodiments following two options may apply depending upon whether MBS service has single or multiple logical channels: Option A includes no LCID value if a MBS service only has only a single logical channel. Since each MBS service only has a single logical channel, during PTM transmission in transmission schemes (b) and (d), different transport blocks from MBS services can be identified according to its G-RNTI. If an MBS service is retransmitted via PTP in transmission scheme (c), as discussed above, MBS services can be multiplexed together with unicast. However, due to a lack of LCID values for MBS service, a UE may need to use HARQ process ID to identify which retransmission the transport block represents from MBS, according to the HARQ process ID used by G-RNTI in the initial transmission. In transmission scheme (a), a novel MBS MAC subheader is introduced in accordance with one or more embodiments to separate MBS services and uncast when they are multiplexed together. An example of MBS MAC subheader is illustrated in FIG.1. As shown, an embodiment includes using a Temporary Mobile Group Identifier (TMGI) within the subheader. As shown, the MBS MAC subheader 100 includes reserved bits 102 designated as “R”, and “F” field 104 and a TMGI 106. The TMGI may be 4 bits 106 and 8 bits at Oct 2 similar to the “L” bit 108. Another example of MBS MAC subheader 200 including a 16 bit “L” field is illustrated in FIG. 2. As shown, reserved bits “R” 202 is shown, an “F” field 204, and TMGI 206. “L” field 208 is shown with two octets, Oct 3 and Oct 4. Referring to FIG. 3, a block diagram illustrates an example of an MBS MAC packet data unit (PDU) for point to point, or unicast transmissions 300. As shown, a MAC subPDU including a MAC SDU 301 is exploded to shown an R/F/TMGI/L subheader 302 as shown in FIG. 1 and 2. As part of the transmission, a MAC subPDU including a MAC CE 306 is shown exploded to illustrate another R/F/LCID/L subheader 308 and a unicast MAC SDU 310. Other example subPDUs are also illustrated including MAC subPDU including padding 320 and a MAC subPDU including a MAC SDU 330 to illustrate possible transmissions. Referring to FIG. 4, a sample MBS MAC PDU for point to multipoint (PTM) is illustrated as block 400. FIG.4 illustrates that a maximum MAC PDU may be transmitted per transport block (TB) per MAC entity. In various embodiments, an LCID value may share the same space as a unicast transmission if a MBS service has single or multiple logical channels. Thus, in an embodiment, each logical channel within MBS services may be allocated with its unique LCID. The same LCID (eLCID) value space may be shared between MBS and unicast. In one embodiment, LCIDs for MBS services may not be reused for unicast. Referring to FIG.5, a flow diagram illustrates a method 500 in accordance with one or more embodiments. As shown, block 510 provides for receiving a request for multicast and broadcast services (MBS) in a wireless communication system capable of Fifth Generation (5G) new radio (NR) communications indicating a discontinuous reception (DRX). For example, as shown above, a MAC layer specifically for 5G communications includes control information to enable both unicast and multicast MBS communications. Block 520 provides a dedicated DRX in a medium access control (MAC) layer for providing the MBS for traffic channel transmission. For example, as shown in FIG. 1 and 2, and 3, a MAC layer subheaders are illustrated that are capable of discontinuous reception. Block 530 provides for encoding a message for transmission to a user equipment (UE) that includes the DRX configuration information. For example, a UE may be monitoring a channel for discontinuous reception and the MAC layer would include configuration information introduced in embodiments in accordance with the present disclosure. One embodiment includes using timer control identifiers such as drx-onDurationTimerMBS, drx- SlotOffsetMBS, drx-InactivityTimerMBS, drx-schedulingPeriiodStartOffsetMBS, drx- RetransmissionTimerDLMBS, and drx-HARQ-RTT-TimerDLMBS. Block 540 provides for dynamically scheduling NR MBS delivery control data using an radio network temporary identifier (RNTI) configured for MBS in a delivery mode for multicasting to provide dynamic scheduling of NR MBS control information. Block 550 provides for dynamically scheduling a retransmission using the RNTI for MBS for retransmission of control information. Block 560 provides for providing a MAC layer subheader with a temporary mobile group identity (TMGI) within the subheader to identify multicast and broadcast communications. For example, if an LCID is not allocated, in an MBS service, the subheader, using TMGI, the subheader can enable multiplexing of multicast and unicast communications at the same time in a same packet data unit (PDU). FIGs. 6, 7 and 8 illustrate various systems, devices, and components that may implement aspects of disclosed embodiments. FIG.6 illustrates a network 600 in accordance with various embodiments. The network 600 may operate in a manner consistent with 3GPP technical specifications for LTE or 5G/NR systems. However, the example embodiments are not limited in this regard and the described embodiments may apply to other networks that benefit from the principles described herein, such as future 3GPP systems, or the like. The network 600 may include a UE 602, which may include any mobile or non-mobile computing device designed to communicate with a RAN 604 via an over-the-air connection. The UE 602 may be communicatively coupled with the RAN 604 by a Uu interface. The UE 602 may be, but is not limited to, a smartphone, tablet computer, wearable computer device, desktop computer, laptop computer, in-vehicle infotainment, in-car entertainment device, instrument cluster, head-up display device, onboard diagnostic device, dashtop mobile equipment, mobile data terminal, electronic engine management system, electronic/engine control unit, electronic/engine control module, embedded system, sensor, microcontroller, control module, engine management system, networked appliance, machine-type communication device, M2M or D2D device, IoT device, etc. In some embodiments, the network 600 may include a plurality of UEs coupled directly with one another via a sidelink interface. The UEs may be M2M/D2D devices that communicate using physical sidelink channels such as, but not limited to, PSBCH, PSDCH, PSSCH, PSCCH, PSFCH, etc. In some embodiments, the UE 602 may additionally communicate with an AP 606 via an over-the-air connection. The AP 606 may manage a WLAN connection, which may serve to offload some/all network traffic from the RAN 604. The connection between the UE 602 and the AP 606 may be consistent with any IEEE 802.11 protocol, wherein the AP 606 could be a wireless fidelity (Wi-Fi®) router. In some embodiments, the UE 602, RAN 604, and AP 606 may utilize cellular-WLAN aggregation (for example, LWA/LWIP). Cellular-WLAN aggregation may involve the UE 602 being configured by the RAN 604 to utilize both cellular radio resources and WLAN resources. The RAN 604 may include one or more access nodes, for example, AN 608. AN 608 may terminate air-interface protocols for the UE 602 by providing access stratum protocols including RRC, PDCP, RLC, MAC, and L1 protocols. In this manner, the AN 608 may enable data/voice connectivity between CN 620 and the UE 602. In some embodiments, the AN 608 may be implemented in a discrete device or as one or more software entities running on server computers as part of, for example, a virtual network, which may be referred to as a CRAN or virtual baseband unit pool. The AN 608 be referred to as a BS, gNB, RAN node, eNB, ng-eNB, NodeB, RSU, TRxP, TRP, etc. The AN 608 may be a macrocell base station or a low power base station for providing femtocells, picocells or other like cells having smaller coverage areas, smaller user capacity, or higher bandwidth compared to macrocells. In embodiments in which the RAN 604 includes a plurality of ANs, they may be coupled with one another via an X2 interface (if the RAN 604 is an LTE RAN) or an Xn interface (if the RAN 604 is a 5G RAN). The X2/Xn interfaces, which may be separated into control/user plane interfaces in some embodiments, may allow the ANs to communicate information related to handovers, data/context transfers, mobility, load management, interference coordination, etc. The ANs of the RAN 604 may each manage one or more cells, cell groups, component carriers, etc. to provide the UE 602 with an air interface for network access. The UE 602 may be simultaneously connected with a plurality of cells provided by the same or different ANs of the RAN 604. For example, the UE 602 and RAN 604 may use carrier aggregation to allow the UE 602 to connect with a plurality of component carriers, each corresponding to a Pcell or Scell. In dual connectivity scenarios, a first AN may be a master node that provides an MCG and a second AN may be secondary node that provides an SCG. The first/second ANs may be any combination of eNB, gNB, ng-eNB, etc. The RAN 604 may provide the air interface over a licensed spectrum or an unlicensed spectrum. To operate in the unlicensed spectrum, the nodes may use LAA, eLAA, and/or feLAA mechanisms based on CA technology with PCells/Scells. Prior to accessing the unlicensed spectrum, the nodes may perform medium/carrier-sensing operations based on, for example, a listen-before-talk (LBT) protocol. In V2X scenarios the UE 602 or AN 608 may be or act as a RSU, which may refer to any transportation infrastructure entity used for V2X communications. An RSU may be implemented in or by a suitable AN or a stationary (or relatively stationary) UE. An RSU implemented in or by: a UE may be referred to as a “UE-type RSU”; an eNB may be referred to as an “eNB-type RSU”; a gNB may be referred to as a “gNB-type RSU”; and the like. In one example, an RSU is a computing device coupled with radio frequency circuitry located on a roadside that provides connectivity support to passing vehicle UEs. The RSU may also include internal data storage circuitry to store intersection map geometry, traffic statistics, media, as well as applications/software to sense and control ongoing vehicular and pedestrian traffic. The RSU may provide very low latency communications required for high speed events, such as crash avoidance, traffic warnings, and the like. Additionally or alternatively, the RSU may provide other cellular/WLAN communications services. The components of the RSU may be packaged in a weatherproof enclosure suitable for outdoor installation and may include a network interface controller to provide a wired connection (e.g., Ethernet) to a traffic signal controller or a backhaul network. In some embodiments, the RAN 604 may be an LTE RAN 610 with eNBs, for example, eNB 612. The LTE RAN 610 may provide an LTE air interface with the following characteristics: SCS of 15 kHz; CP-OFDM waveform for DL and SC-FDMA waveform for UL; turbo codes for data and TBCC for control; etc. The LTE air interface may rely on CSI- RS for CSI acquisition and beam management; PDSCH/PDCCH DMRS for PDSCH/PDCCH demodulation; and CRS for cell search and initial acquisition, channel quality measurements, and channel estimation for coherent demodulation/detection at the UE. The LTE air interface may operating on sub-6 GHz bands. In some embodiments, the RAN 604 may be an NG-RAN 614 with gNBs, for example, gNB 616, or ng-eNBs, for example, ng-eNB 618. The gNB 616 may connect with 5G-enabled UEs using a 5G NR interface. The gNB 616 may connect with a 5G core through an NG interface, which may include an N2 interface or an N3 interface. The ng-eNB 618 may also connect with the 5G core through an NG interface, but may connect with a UE via an LTE air interface. The gNB 616 and the ng-eNB 618 may connect with each other over an Xn interface. In some embodiments, the NG interface may be split into two parts, an NG user plane (NG-U) interface, which carries traffic data between the nodes of the NG-RAN 614 and a UPF 648 (e.g., N3 interface), and an NG control plane (NG-C) interface, which is a signaling interface between the nodes of the NG-RAN614 and an AMF 644 (e.g., N2 interface). The NG-RAN 614 may provide a 5G-NR air interface with the following characteristics: variable SCS; CP-OFDM for DL, CP-OFDM and DFT-s-OFDM for UL; polar, repetition, simplex, and Reed-Muller codes for control and LDPC for data. The 5G-NR air interface may rely on CSI-RS, PDSCH/PDCCH DMRS similar to the LTE air interface. The 5G-NR air interface may not use a CRS, but may use PBCH DMRS for PBCH demodulation; PTRS for phase tracking for PDSCH; and tracking reference signal for time tracking. The 5G- NR air interface may operating on FR1 bands that include sub-6 GHz bands or FR2 bands that include bands from 24.25 GHz to 52.6 GHz. The 5G-NR air interface may include an SSB that is an area of a downlink resource grid that includes PSS/SSS/PBCH. In some embodiments, the 5G-NR air interface may utilize BWPs for various purposes. For example, BWP can be used for dynamic adaptation of the SCS. For example, the UE 602 can be configured with multiple BWPs where each BWP configuration has a different SCS. When a BWP change is indicated to the UE 602, the SCS of the transmission is changed as well. Another use case example of BWP is related to power saving. In particular, multiple BWPs can be configured for the UE 602 with different amounts of frequency resources (for example, PRBs) to support data transmission under different traffic loading scenarios. A BWP containing a smaller number of PRBs can be used for data transmission with a small traffic load while allowing power saving at the UE 602 and in some cases at the gNB 616. A BWP containing a larger number of PRBs can be used for scenarios with higher traffic loads. The RAN 604 is communicatively coupled to CN 620 that includes network elements to provide various functions to support data and telecommunications services to customers/subscribers (for example, users of UE 602). The components of the CN 620 may be implemented in one physical node or separate physical nodes. In some embodiments, NFV may be utilized to virtualize any or all of the functions provided by the network elements of the CN 620 onto physical compute/storage resources in servers, switches, etc. A logical instantiation of the CN 620 may be referred to as a network slice, and a logical instantiation of a portion of the CN 620 may be referred to as a network sub-slice. In some embodiments, the CN 620 may be an LTE CN 622, which may also be referred to as an EPC. The LTE CN 622 may include MME 624, SGW 626, SGSN 628, HSS 630, PGW 632, and PCRF 634 coupled with one another over interfaces (or “reference points”) as shown. Functions of the elements of the LTE CN 622 may be briefly introduced as follows. The MME 624 may implement mobility management functions to track a current location of the UE 602 to facilitate paging, bearer activation/deactivation, handovers, gateway selection, authentication, etc. The SGW 626 may terminate an S1 interface toward the RAN and route data packets between the RAN and the LTE CN 622. The SGW 626 may be a local mobility anchor point for inter-RAN node handovers and also may provide an anchor for inter-3GPP mobility. Other responsibilities may include lawful intercept, charging, and some policy enforcement. The SGSN 628 may track a location of the UE 602 and perform security functions and access control. In addition, the SGSN 628 may perform inter-EPC node signaling for mobility between different RAT networks; PDN and S-GW selection as specified by MME 624; MME selection for handovers; etc. The S3 reference point between the MME 624 and the SGSN 628 may enable user and bearer information exchange for inter-3GPP access network mobility in idle/active states. The HSS 630 may include a database for network users, including subscription-related information to support the network entities’ handling of communication sessions. The HSS 630 can provide support for routing/roaming, authentication, authorization, naming/addressing resolution, location dependencies, etc. An S6a reference point between the HSS 630 and the MME 624 may enable the transfer of subscription and authentication data for authenticating/authorizing user access to the LTE CN 620. The PGW 632 may terminate an SGi interface toward a data network (DN) 636 that may include an application/content server 638. The PGW 632 may route data packets between the LTE CN 622 and the data network 636. The PGW 632 may be coupled with the SGW 626 by an S5 reference point to facilitate user plane tunneling and tunnel management. The PGW 632 may further include a node for policy enforcement and charging data collection (for example, PCEF). Additionally, the SGi reference point between the PGW 632 and the data network 636 may be an operator external public, a private PDN, or an intra-operator packet data network, for example, for provision of IMS services. The PGW 632 may be coupled with a PCRF 634 via a Gx reference point. The PCRF 634 is the policy and charging control element of the LTE CN 622. The PCRF 634 may be communicatively coupled to the app/content server 638 to determine appropriate QoS and charging parameters for service flows. The PCRF 632 may provision associated rules into a PCEF (via Gx reference point) with appropriate TFT and QCI. In some embodiments, the CN 620 may be a 5GC 640. The 5GC 640 may include an AUSF 642, AMF 644, SMF 646, UPF 648, NSSF 650, NEF 652, NRF 654, PCF 656, UDM 658, and AF 660 coupled with one another over interfaces (or “reference points”) as shown. Functions of the elements of the 5GC 640 may be briefly introduced as follows. The AUSF 642 may store data for authentication of UE 602 and handle authentication- related functionality. The AUSF 642 may facilitate a common authentication framework for various access types. In addition to communicating with other elements of the 5GC 640 over reference points as shown, the AUSF 642 may exhibit an Nausf service-based interface. The AMF 644 may allow other functions of the 5GC 640 to communicate with the UE 602 and the RAN 604 and to subscribe to notifications about mobility events with respect to the UE 602. The AMF 644 may be responsible for registration management (for example, for registering UE 602), connection management, reachability management, mobility management, lawful interception of AMF-related events, and access authentication and authorization. The AMF 644 may provide transport for SM messages between the UE 602 and the SMF 646, and act as a transparent proxy for routing SM messages. AMF 644 may also provide transport for SMS messages between UE 602 and an SMSF. AMF 644 may interact with the AUSF 642 and the UE 602 to perform various security anchor and context management functions. Furthermore, AMF 644 may be a termination point of a RAN CP interface, which may include or be an N2 reference point between the RAN 604 and the AMF 644; and the AMF 644 may be a termination point of NAS (N1) signaling, and perform NAS ciphering and integrity protection. AMF 644 may also support NAS signaling with the UE 602 over an N3 IWF interface. The SMF 646 may be responsible for SM (for example, session establishment, tunnel management between UPF 648 and AN 608); UE IP address allocation and management (including optional authorization); selection and control of UP function; configuring traffic steering at UPF 648 to route traffic to proper destination; termination of interfaces toward policy control functions; controlling part of policy enforcement, charging, and QoS; lawful intercept (for SM events and interface to LI system); termination of SM parts of NAS messages; downlink data notification; initiating AN specific SM information, sent via AMF 644 over N2 to AN 608; and determining SSC mode of a session. SM may refer to management of a PDU session, and a PDU session or “session” may refer to a PDU connectivity service that provides or enables the exchange of PDUs between the UE 602 and the data network 636. The UPF 648 may act as an anchor point for intra-RAT and inter-RAT mobility, an external PDU session point of interconnect to data network 636, and a branching point to support multi-homed PDU session. The UPF 648 may also perform packet routing and forwarding, perform packet inspection, enforce the user plane part of policy rules, lawfully intercept packets (UP collection), perform traffic usage reporting, perform QoS handling for a user plane (e.g., packet filtering, gating, UL/DL rate enforcement), perform uplink traffic verification (e.g., SDF-to-QoS flow mapping), transport level packet marking in the uplink and downlink, and perform downlink packet buffering and downlink data notification triggering. UPF 648 may include an uplink classifier to support routing traffic flows to a data network. The NSSF 650 may select a set of network slice instances serving the UE 602. The NSSF 650 may also determine allowed NSSAI and the mapping to the subscribed S-NSSAIs, if needed. The NSSF 650 may also determine the AMF set to be used to serve the UE 602, or a list of candidate AMFs based on a suitable configuration and possibly by querying the NRF 654. The selection of a set of network slice instances for the UE 602 may be triggered by the AMF 644 with which the UE 602 is registered by interacting with the NSSF 650, which may lead to a change of AMF. The NSSF 650 may interact with the AMF 644 via an N22 reference point; and may communicate with another NSSF in a visited network via an N31 reference point (not shown). Additionally, the NSSF 650 may exhibit an Nnssf service-based interface. The NEF 652 may securely expose services and capabilities provided by 3GPP network functions for third party, internal exposure/re-exposure, AFs (e.g., AF 660), edge computing or fog computing systems, etc. In such embodiments, the NEF 652 may authenticate, authorize, or throttle the AFs. NEF 652 may also translate information exchanged with the AF 660 and information exchanged with internal network functions. For example, the NEF 652 may translate between an AF-Service-Identifier and an internal 5GC information. NEF 652 may also receive information from other NFs based on exposed capabilities of other NFs. This information may be stored at the NEF 652 as structured data, or at a data storage NF using standardized interfaces. The stored information can then be re-exposed by the NEF 652 to other NFs and AFs, or used for other purposes such as analytics. Additionally, the NEF 652 may exhibit an Nnef service-based interface. The NRF 654 may support service discovery functions, receive NF discovery requests from NF instances, and provide the information of the discovered NF instances to the NF instances. NRF 654 also maintains information of available NF instances and their supported services. As used herein, the terms “instantiate,” “instantiation,” and the like may refer to the creation of an instance, and an “instance” may refer to a concrete occurrence of an object, which may occur, for example, during execution of program code. Additionally, the NRF 654 may exhibit the Nnrf service-based interface. The PCF 656 may provide policy rules to control plane functions to enforce them, and may also support unified policy framework to govern network behavior. The PCF 656 may also implement a front end to access subscription information relevant for policy decisions in a UDR of the UDM 658. In addition to communicating with functions over reference points as shown, the PCF 656 exhibit an Npcf service-based interface. The UDM 658 may handle subscription-related information to support the network entities’ handling of communication sessions, and may store subscription data of UE 602. For example, subscription data may be communicated via an N8 reference point between the UDM 658 and the AMF 644. The UDM 658 may include two parts, an application front end and a UDR. The UDR may store subscription data and policy data for the UDM 658 and the PCF 656, and/or structured data for exposure and application data (including PFDs for application detection, application request information for multiple UEs 602) for the NEF 652. The Nudr service-based interface may be exhibited by the UDR 221 to allow the UDM 658, PCF 656, and NEF 652 to access a particular set of the stored data, as well as to read, update (e.g., add, modify), delete, and subscribe to notification of relevant data changes in the UDR. The UDM may include a UDM-FE, which is in charge of processing credentials, location management, subscription management and so on. Several different front ends may serve the same user in different transactions. The UDM-FE accesses subscription information stored in the UDR and performs authentication credential processing, user identification handling, access authorization, registration/mobility management, and subscription management. In addition to communicating with other NFs over reference points as shown, the UDM 658 may exhibit the Nudm service-based interface. The AF 660 may provide application influence on traffic routing, provide access to NEF, and interact with the policy framework for policy control. In some embodiments, the 5GC 640 may enable edge computing by selecting operator/3 rd party services to be geographically close to a point that the UE 602 is attached to the network. This may reduce latency and load on the network. To provide edge-computing implementations, the 5GC 640 may select a UPF 648 close to the UE 602 and execute traffic steering from the UPF 648 to data network 636 via the N6 interface. This may be based on the UE subscription data, UE location, and information provided by the AF 660. In this way, the AF 660 may influence UPF (re)selection and traffic routing. Based on operator deployment, when AF 660 is considered to be a trusted entity, the network operator may permit AF 660 to interact directly with relevant NFs. Additionally, the AF 660 may exhibit an Naf service-based interface. The data network 636 may represent various network operator services, Internet access, or third party services that may be provided by one or more servers including, for example, application/content server 638.

The foregoing description of one or more implementations provides illustration and description, but is not intended to be exhaustive or to limit the scope of embodiments to the precise form disclosed. Modifications and variations are possible in light of the above teachings or may be acquired from practice of various embodiments. Unless used differently herein, terms, definitions, and abbreviations may be consistent with terms, definitions, and abbreviations defined in 3GPP TR 21.905 v16.0.0 (2019-06). For the purposes of the present document, the following abbreviations may apply to the examples and embodiments discussed herein.

Table 1 - Abbreviations: In the above disclosure, reference has been made to the accompanying drawings, which form a part hereof, which illustrate specific implementations in which the present disclosure may be practiced. It is understood that other implementations may be utilized, and structural changes may be made without departing from the scope of the present disclosure. References in the specification to “one embodiment,” “an embodiment,” “an example embodiment,” “an example embodiment,” “example implementation,” etc., indicate that the embodiment or implementation described may include a particular feature, structure, or characteristic, but every embodiment or implementation may not necessarily include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment or implementation. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment or implementation, one skilled in the art will recognize such feature, structure, or characteristic in connection with other embodiments or implementations whether or not explicitly described. For example, various features, aspects, and actions described above with respect to an autonomous parking maneuver are applicable to various other autonomous maneuvers and must be interpreted accordingly. Implementations of the systems, apparatuses, devices, and methods disclosed herein may comprise or utilize one or more devices that include hardware, such as, for example, one or more processors and system memory, as discussed herein. An implementation of the devices, systems, and methods disclosed herein may communicate over a computer network. A “network” is defined as one or more data links that enable the transport of electronic data between computer systems and/or modules and/or other electronic devices. When information is transferred or provided over a network or another communications connection (either hardwired, wireless, or any combination of hardwired or wireless) to a computer, the computer properly views the connection as a transmission medium. Transmission media can include a network and/or data links, which can be used to carry desired program code means in the form of computer-executable instructions or data structures and which can be accessed by a general purpose or special purpose computer. Combinations of the above should also be included within the scope of non-transitory computer-readable media. Computer-executable instructions comprise, for example, instructions and data which, when executed at a processor, cause the processor to perform a certain function or group of functions. The computer-executable instructions may be, for example, binaries, intermediate format instructions such as assembly language, or even source code. Although the subject matter has been described in language specific to structural features and/or methodological acts, it is to be understood that the subject matter defined in the appended claims is not necessarily limited to the described features or acts described above. Rather, the described features and acts are disclosed as example forms of implementing the claims. A memory device can include any one memory element or a combination of volatile memory elements (e.g., random access memory (RAM, such as DRAM, SRAM, SDRAM, etc.)) and non-volatile memory elements (e.g., ROM, hard drive, tape, CDROM, etc.). Moreover, the memory device may incorporate electronic, magnetic, optical, and/or other types of storage media. In the context of this document, a “non-transitory computer-readable medium” can be, for example but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device. More specific examples (a non-exhaustive list) of the computer-readable medium would include the following: a portable computer diskette (magnetic), a random-access memory (RAM) (electronic), a read-only memory (ROM) (electronic), an erasable programmable read-only memory (EPROM, EEPROM, or Flash memory) (electronic), and a portable compact disc read-only memory (CD ROM) (optical). Note that the computer-readable medium could even be paper or another suitable medium upon which the program is printed, since the program can be electronically captured, for instance, via optical scanning of the paper or other medium, then compiled, interpreted or otherwise processed in a suitable manner if necessary, and then stored in a computer memory. Those skilled in the art will appreciate that the present disclosure may be practiced in network computing environments with many types of computer system configurations, including in-dash vehicle computers, personal computers, desktop computers, laptop computers, message processors, nomadic devices, multi-processor systems, microprocessor- based or programmable consumer electronics, network PCs, minicomputers, mainframe computers, mobile telephones, PDAs, tablets, pagers, routers, switches, various storage devices, and the like. The disclosure may also be practiced in distributed system environments where local and remote computer systems, which are linked (either by hardwired data links, wireless data links, or by any combination of hardwired and wireless data links) through a network, both perform tasks. In a distributed system environment, program modules may be located in both the local and remote memory storage devices. Further, where appropriate, the functions described herein can be performed in one or more of hardware, software, firmware, digital components, or analog components. For example, one or more application specific integrated circuits (ASICs) can be programmed to carry out one or more of the systems and procedures described herein. Certain terms are used throughout the description, and claims refer to particular system components. As one skilled in the art will appreciate, components may be referred to by different names. This document does not intend to distinguish between components that differ in name, but not function. At least some embodiments of the present disclosure have been directed to computer program products comprising such logic (e.g., in the form of software) stored on any computer- usable medium. Such software, when executed in one or more data processing devices, causes a device to operate as described herein. While various embodiments of the present disclosure have been described above, it should be understood that they have been presented by way of example only, and not limitation. It will be apparent to persons skilled in the relevant art that various changes in form and detail can be made therein without departing from the spirit and scope of the present disclosure. Thus, the breadth and scope of the present disclosure should not be limited by any of the above-described example embodiments but should be defined only in accordance with the following claims and their equivalents. The foregoing description has been presented for the purposes of illustration and description. It is not intended to be exhaustive or to limit the present disclosure to the precise form disclosed. Many modifications and variations are possible in light of the above teaching. Further, it should be noted that any or all of the aforementioned alternate implementations may be used in any combination desired to form additional hybrid implementations of the present disclosure. For example, any of the functionality described with respect to a particular device or component may be performed by another device or component. Further, while specific device characteristics have been described, embodiments of the disclosure may relate to numerous other device characteristics. Further, although embodiments have been described in language specific to structural features and/or methodological acts, it is to be understood that the disclosure is not necessarily limited to the specific features or acts described. Rather, the specific features and acts are disclosed as illustrative forms of implementing the embodiments. Conditional language, such as, among others, “can,” “could,” “might,” or “may,” unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain embodiments could include, while other embodiments may not include, certain features, elements, and/or steps. Thus, such conditional language is not generally intended to imply that features, elements, and/or steps are in any way required for one or more embodiments.
