DETAILED DESCRIPTION

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).

For 5G systems, high frequency band communication has attracted significant attention from the industry, since it can provide wider bandwidth to support the future integrated communication system. The beam forming is an important technology for the implementation of high frequency band system due to the fact that the beam forming gain can compensate the severe path loss caused by atmospheric attenuation, improve the SNR, and enlarge the coverage area. By aligning the transmission beam to the target UE, radiated energy is focused for higher energy efficiency, and mutual UE interference is suppressed.

As defined in NR, one slot has 14 symbols. For systems operating above 52.6GHz carrier frequency, when larger subcarrier spacing, e.g., 480kHz or 960kHz is employed, slot duration can be very short. For instance, for 960kHz subcarrier spacing, one slot duration is approximately 15.6 m s . This extremely short slot duration may not be sufficient for the processing of higher layer, including MAC and RLC, etc. In this case, certain mechanisms may need to be defined to allow long transmission duration and adequate processing time for higher layer.

To address this issue, multi-Transmission Time Interval (TTI) based scheduling can be employed, where one physical downlink control channel (PDCCH) can be used to schedule multiple physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH) carrying independent transport block (TBs). Based on this mechanism, scheduler implementation and higher layer processing burdened can be relaxed, while maintaining same peak data rate.

Figure 1 illustrates one example of multi-TTI scheduling for PDSCHs. In this example, four PDSCHs (PDSCH#0-3) with different transport blocks (TB) are scheduled by a single DCI. Note that although in the figure, different time domain resource allocation is allocated for different PDSCHs in different slots, the design can be extended to the case when same time domain resource allocation is allocated for PDSCH transmissions.

In NR, multiple transmit and receive points (TRP)s can be utilized to transmit and receive data and control channel, which can help in improving the reliability for communication. Figure 2 illustrates one example of multi-TRP operation. Note that when multi-TTI scheduling for PDSCH and PUSCH transmission is employed with multi-TRP operation, certain design aspects may need to be considered. Among other things, embodiments of the present disclosure are directed to multi-PDSCH and multi-PUSCH scheduling for multi-TRP operation for systems operating above 52.6GHz carrier frequency. In particular, some embodiments are directed to:

• multi-PDSCH scheduling under multi-TRP operation

• multi-PUSCH scheduling under multi-TRP operation

• Scheduling of multi-PDSCH/PUSCH transmissions using a single DCI.

Multi-PDSCH scheduling under multi-TRP operation

As mentioned above, for systems operating above the 52.6GHz carrier frequency, when larger subcarrier spacing, e.g., 480kHz or 960kHz is employed, slot duration can be very short. For instance, for 960kHz subcarrier spacing, one slot duration is approximately 15.6ps. This extremely short slot duration may not be sufficient for the processing of higher layer, including MAC and RLC, etc. In this case, certain mechanisms may need to be defined to allow long transmission duration and adequate processing time for higher layer.

To address this issue, multi-TTI based scheduling can be employed, where one PDCCH can be used to schedule multiple PDSCHs or PUSCH carrying independent TBs. Based on this mechanism, scheduler implementation and higher layer processing burdened can be relaxed, while maintaining same peak data rate.

In NR, multiple transmit and receive points (TRP)s can be utilized to transmit and receive data and control channel, which can help in improving the reliability for communication. Note that when multi-TTI scheduling for PDSCH and PUSCH transmission is employed with multi- TRP operation, certain design aspects may need to be considered.

Embodiments for multi-PDSCH scheduling under multi-TRP operation are provided as follows:

In one embodiment, for FDM-based schemes (e.g., FDM schemes A and B), the same frequency domain resource allocation (FDRA) is allocated for all scheduled PDSCHs for different TRPs in case when multi-PDSCH scheduling is applied. More specifically, when for a UE configured by the higher layer parameter RepSchemeEnabler set to 'FDMSchemeA' or 'FDMSchemeB', and when the UE is indicated with two TCI states in a codepoint of the DCI field 'Transmission Configuration Indication and DM-RS port(s) within one CDM group in the DCI field "Antenna Port(s)", FDRA can be applied for all scheduled PDSCHs.

In another embodiment, when multi-PDSCH scheduling is applied for TDM scheme A for multi-TRP operation, two repetitions in a slot are applied for all the scheduled PDSCHs, where different TRPs or TCI states are applied for each repetition of a PDSCH. In particular, if two TCI states are indicated by the DCI field 'Transmission Configuration Indication', a first TCI state is applied for a first transmission occasion of a PDSCH with all the scheduled PDSCHs, where a second TCI state is applied for a second transmission occasion of the PDSCH.

In addition, the same number of symbols are applied for the first and second transmission occasions for a PDSCH for multi-PDSCH scheduling. Further, same or different starting symbol offsets may be applied for the last symbol of the first transmission occasions and first symbol of the second transmission occasions. Note that depending on the TDRA configuration, different SLIV may be allocated for different PDSCHs in case of multi-PDSCH scheduling.

Figure 3 illustrates one example of multi-PDSCH scheduling with multi-TRP operation TDM scheme A In the example, two PDSCHs are scheduled by a single DCI. Further, same number of symbols is allocated for the two PDSCHs, respectively and starting symbol offset is 2 for the two PDSCHs. For TDM scheme A, a first and second TCI state (TRP#0 and #1, respectively) is applied for a first and second transmission occasion of a first PDSCH, followed by the first and second TCI state for a first and second transmission occasion of a second PDSCH.

In another embodiment, for multi-PDSCH scheduling, when repetitions are applied for the transmission of scheduled PDSCHs, different beams can be applied for all the scheduled PDSCHs in different transmission occasions.

Note that for repetition of each PDSCH, same time domain resource allocation may be applied. In one example, same start and length indicator value (SLIV) can be applied for the repetition of a PDSCH in case of multi-PDSCH scheduling.

In one option, when two TCI states are indicated by the DCI field 'Transmission Configuration Indication' for multi-PDSCH scheduling, a first TCI state is applied for a first transmission occasions of all the scheduled PDSCHs, followed by a second TCI state for a second transmission occasions of all the scheduled PDSCHs.

Further, when more than 2 repetitions are used for the transmission of PDSCHs, either cyclic beam mapping or sequential beam mapping can be applied as defined in Rel-16. In this case, beam cycling pattern is applied for all the scheduled PDSCHs.

In particular, when cyclic mapping is enabled, the first and second TCI states are applied to the first and second transmission occasions for all the scheduled PDSCHs, respectively, and the same TCI mapping pattern continues to the remaining transmission occasions for all the scheduled PDSCHs. In addition, when sequential mapping is enabled, first TCI state is applied to the first and second transmissions for all the scheduled PDSCHs, and the second TCI state is applied to the third and fourth transmissions for all the scheduled PDSCHs, and the same TCI mapping pattern continues to the remaining transmission occasions of all the scheduled PDSCHs.

Figure 4 illustrates one example of multi-PDSCH scheduling with multi-TRP operation. In this example, two PDSCHs are scheduled by a single DCI and each PDSCH has two repetitions. Based on this option, the first TCI state (or TRP#0) is applied for a first transmission occasion of a first PDSCH, followed by the first TCI state for a first transmission occasion of a second PDSCH, then the second TCI state (or TRP#1) for the second transmission of the first PDSCH, then the second TCI state for the second transmission occasion of the second PDSCH.

In another option, when two TCI states are indicated by the DCI field 'Transmission Configuration Indication ¹ for multi-PDSCH scheduling, a first and second TCI states are applied for repetitions of a first PDSCH, followed by the first and second TCI state for repetitions of a second PDSCH. Within the repetitions of PDSCHs, either cyclic beam mapping pattern or sequential beam mapping pattern as mentioned above can be applied

Figure 5 illustrates one example of multi-PDSCH scheduling with multi-TRP operation. In this example, two PDSCHs are scheduled by a single DCI and each PDSCH has two repetitions. Based on this option, a first TCI state (or TRP#0) is applied for a first transmission occasion of a first PDSCH, followed by a second TCI state (or TRP#1) for a second transmission occasion of the first PDSCH, then the first TCI state for the first transmission of the second PDSCH, then the second TCI state for the second transmission occasion of the second PDSCH.

Multi-PUSCH scheduling under multi-TRP operation

Embodiments of multi -PUSCH scheduling under multi-TRP operation are provided as follows:

In one embodiment, for PUSCH repetition type A, when repetitions are applied for the transmission of scheduled PUSCHs in case when multi-PUSCH scheduling is applied, different beams can be applied for all the scheduled PUSCHs in different transmission occasions. Further, same mechanisms as mentioned above when repetitions are applied for the transmission of scheduled PDSCHs can be applied for PUSCH repetition type A. For instance, in the Figure 4 and Figure 5, PDSCH can be replaced by PUSCH, which can be applied for the PUSCH repetition type A in case of multi-PUSCH scheduling.

In another embodiment, for PUSCH repetition type B, when two sounding reference signal resource indicators (SRI) are indicated or configured in the DCI for multi-PUSCH scheduling, a first and second SRI states are applied for nominal repetitions of a first PUSCH, followed by the first and second SRI state for nominal repetitions of a second PUSCH. Within the nominal repetitions of PUSCHs, either cyclic beam mapping pattern or sequential beam mapping pattern as mentioned above can be applied.

Figure 6 illustrates one example of multi-PUSCH scheduling with multi-TRP operation for PUSCH with repetition type B. In the example, two PUSCHs with repetition type B are scheduled by a single DCI and each PUSCH has four repetitions. Based on this option, a first SRI state (or TRP#0) is applied for a first and third nominal repetition of a first PUSCH and a first and third nominal repetition of a second PUSCH; while a second SRI state (or TRP#1) is applied for a second and fourth nominal repetition of a first PUSCH and a second and fourth nominal repetition of a second PUSCH;

In another embodiment, in Rel-16 multi-PUSCH scheduling, when two PUSCHs are scheduled by a DCI, aperiodic channel state information (A-CSI) is transmitted on the last PUSCH. Further, when more than two PUSCHs are scheduled by a DCI, A-CSI is transmitted on the penultimate (second last) scheduled PUSCH.

In case of multi-TRP operation, if a PUSCH is repeated two times and respectively transmitted for the two TRPs, A-CSI is transmitted on both the two repetitions of the PUSCHs using two beams, respectively. Further, if a PUSCH is repeated N (N > 2) times and transmitted to the two TRPs, A-CSI is transmitted on the first and second repetition of the PUSCH using the two beams respectively. Alternatively, if a PUSCH is repeated N (N ³ 2) times and transmitted to the two TRPs, A-CSI is transmitted on the all N repetitions of the PUSCH using two beams based on the beam cycling pattern for PUSCH transmission.

In case of multi-TRP operation, when PUSCH repetition type A is applied for multi- PUSCH scheduling, A-CSI is transmitted on the first repetition of the penultimate scheduled PUSCH using a first beam while A-CSI is transmitted on the second repetition of the penultimate scheduled PUSCH using a second beam.

Further, in case of multi-TRP operation, when PUSCH repetition type B is applied for multi-PUSCH scheduling, A-CSI is transmitted on the first actual repetition of the penultimate scheduled PUSCH using a first beam, while A-CSI is transmitted on the X-th actual repetition of the penultimate scheduled PUSCH using a second beam, where first actual repetition has same number of symbols as the X actual repetition. Note that the UE does not expect the first actual repetition corresponding to the first beam and the X-th actual repetition corresponding to the second beam to have a single symbol duration

Scheduling of multi-PDSCH/PUSCH transmission using a single DCI

Embodiments of scheduling of multi-PDSCH/PUSCH transmission using a single DCI are provided as follows:

In one embodiment, to reduce the overhead of multiple PDCCH transmissions with scheduling DCIs for different UEs, a single DCI can be used to schedule a group of UEs simultaneously for multiple PDSCHs or PUSCHs. In this case, the UE, upon reception of scheduling DCI, identifies a set of parameters indicating its PDSCH/PUSCH transmission. In some embodiments, this set of parameters includes a duration of PDSCH/PUSCH transmission and offset from the scheduling DCI for each scheduled UE as illustrated in Figure 7.

Note that when scheduling multiple UEs with multi-PDSCH or multi-PUSCH transmission using a single DCI, a common Radio Network Temporary Identifier (RNTI) may be configured or indicated by higher layers via remaining minimum system information (RMSI), other system information (OSI) or dedicated radio resource control (RRC) signalling

Scheduling of multiple UEs with the same DCI, as illustrated in Figure 7, may be especially useful when some of the DCI parameters are shared between the scheduled UEs. For example, the UEs scheduled in the downlink may be served with the same Tx beam. In this case, the same single TCI state from the DCI could be used by the scheduled UEs. However, in some embodiments, Tx beam indication may differ for the UEs scheduled with the same DCI. In this case, different beam indication per scheduled UE is also included into the scheduling DCI.

Time Domain Resource Allocation for Data Channel

In NR Rel-15, starting and length indicator value (SLIV) is used to indicate the time domain resource allocation (TDRA) within a slot for data transmission. Further, a list of time domain resource allocations can be configured by higher layers, which includes kO or k2, mapping type and SLIV in a slot. In particular, kO and k2 are the slot offset between downlink control information (DCI) and its scheduled physical downlink shared channel (PDSCH) and physical uplink shared channel (PUSCH), respectively. Figure 8 illustrates one example of single PDSCH scheduling. In the figure, kO = 1 and starting symbol and length of PDSCH is symbol #2 and 10 symbols, respectively.

Further, in Rel-16, number of repetitions can be configured as part of TDRA for the PDSCH and PUSCH transmission. When one TDRA with number of repetitions from a list of TDRA is selected and indicated in the downlink control information (DCI), the number of repetitions can be applied for the transmission of PDSCH and PUSCH.

For system operating above 52.6GHz carrier frequency, when a large subcarrier spacing, e.g., 480kHz or 960kHz is used, symbol and slot duration is very short, which may pose certain constraint for scheduler implementation. To alleviate scheduler constraint and relax higher layer processing burden, multi-transmit time interval (TTI) based scheduling can be employed, where one physical downlink control channel (PDCCH) can be used to schedule multiple PDSCHs or PUSCH carrying independent TBs. Based on this mechanism, scheduler implementation and higher layer processing burdened can be relaxed, while maintaining same peak data rate.

To further improve the coverage for uplink transmission, single transport block (TB) may span more than one slots. This can be applied in conjunction with multi-PDSCH or multi-PUSCH scheduling. Similar mechanism can also be applied when repetition is used for PDSCH and PUSCH transmission. Considering all different scheduling mechanisms for data transmission, including single slot transmission, multi-slot transmission, TB spanning multiple slots, repetitions, etc., time domain resource allocation needs to be enhanced for PDSCH and PUSCH transmission.

Embodiments herein provide unified mechanisms for time domain resource allocation for data transmission.

A unified mechanism for time domain resource allocation for data transmission

As mentioned above, for system operating above 52.6GHz carrier frequency, when a large subcarrier spacing, e.g., 480kHz or 960kHz is used, symbol and slot duration is very short, which may pose certain constraint for scheduler implementation. To alleviate scheduler constraint and relax higher layer processing burden, multi-transmit time interval (TTI) based scheduling can be employed, where one physical downlink control channel (PDCCH) can be used to schedule multiple PDSCHs or PUSCH carrying independent TBs. Based on this mechanism, scheduler implementation and higher layer processing burdened can be relaxed, while maintaining same peak data rate.

To further improve the coverage for uplink transmission, single transport block (TB) may span more than one slots. This can be applied in conjunction with multi-PDSCH or multi-PUSCH scheduling. Similar mechanism can also be applied when repetition is used for PDSCH and PUSCH transmission. Considering all different scheduling mechanisms for data transmission, including single slot transmission, multi-slot transmission, TB spanning multiple slots, repetitions, etc., time domain resource allocation needs to be enhanced for PDSCH and PUSCH transmission.

Embodiments of a unified mechanism for time domain resource allocation for data transmission are provided as follows:

In one embodiment, one TDRA table may be used to schedule one or more following types of data transmission:

• Single PDSCH or PUSCH, where each PDSCH or PUSCH is scheduled within a slot

• Single PDSCH or PUSCH with repetition, where each PDSCH or PUSCH is scheduled with more than one repetition.

• Single PDSCH or PUSCH, where each PDSCH or PUSCH spans more than one slot, as shown in Figure 9.

• Multi-PDSCH or multi-PUSCH transmission, where each PDSCH or PUSCH is located within a slot, as shown in Figure 1 introduced previously. • Multi-PDSCH or multi-PUSCH transmission, where each PDSCH or PUSCH is scheduled with more than one repetition and each repetition is located within a slot, as shown in Figure 10.

• Multi-PDSCH or multi-PUSCH transmission, where each PDSCH or PUSCH carrying a TB spans more than one slot, as shown in Figure 11. Note that although consecutive symbols are allocated for PDSCH with a TB spanning multiple slots, the design can be straightforwardly extended to the case when same TDRA is applied for different slots for scheduled PDSCHs.

Note that for the above types of data transmission, each PDSCH or PUSCH may carry one or more TB or more than one code block groups (CBG).

Further, when repetition is employed for the transmission of PDSCH or PUSCH, repetition type A or type B may be employed for the PDSCH or PUSCH repetition. For repetition type A, each repetition is located within a slot; while for repetition type B, consecutive SLIV is allocated for TDRA for PDSCH or PUSCH repetition.

Note that the following embodiments may not be limited to repetition type A or type B. For instance, different SLIVs may be allocated for different repetitions in different slots and different repetitions may be non-consecutive in time.

Further, if a UE is configured to support a subset or all type of the aforementioned type of data transmission, a subset of TDRA lists can be configured for one type of data transmissions. When UE is scheduled with an entry of the configured TDRA list, UE can derive the type of data transmission for PDSCH and PUSCH.

Table 1 illustrates one example of TDRA list partition to indicate the type of data transmission. In the example, if all different types of data transmissions are configured for a UE, TDRA list partition to indicate the type of data transmission. In particular, the number of entries for different types of data transmission can be predefined in the specification or configured by higher layers via MSI, RMSI (SIB1), OSI or RRC signalling.

In the example, NO, Nl, N2N3 can be configured by higher layers via MSI, RMSI (SIB1), OSI or RRC signalling. Further, entries from 0 to NO-1 are for TDRA list for single PDSCH or PUSCH with or without repetition; entries from NO to Nl-1 are for TDRA list for single PDSCH or PUSCH with a TB spanning more than one slot; entries from Nl to N2-1 are for TDRA list for multi-PDSCH or multi-PUSCH transmission with or without repetition for each scheduled PDSCH or PUSCH; entries from N2 to N3-1 are for TDRA list for multi-PDSCH or multi-PUSCH transmission, where each PDSCH or PUSCH carrying a TB spans more than one slot. Table 1. TDRA list partition to indicate the type of data transmission

In another embodiment, indication of one or more of the above type of data transmissions can be configured by higher layers via minimum system information (MSI), remaining minimum system information (RMSI), other system information (OSI) or dedicated radio resource control (RRC) signalling or indicated in the DCI or a combination thereof.

In one example, 2-bit identifier for type of data transmission can be explicitly indicated in the DCI, as shown in Table 2. Note that the identifier may also be indicated as a part of TDRA. Table 2. Identifier for type of data transmission: Example 1 In another example, 1-bit identifier for type of data transmission can be explicitly indicated in the DCI, as shown in Table 2. In this case, the number of scheduled PDSCHs or PUSCHs can be implicitly derived in accordance with the number of TDRA or SLIVs for the scheduled entry of TDRA list.

Table 3. Identifier for type of data transmission: Example 2

In another embodiment, for each entry of TDRA list, one or more parameters for TDRA can be commonly applied for all the scheduled PDSCHs or PUSCHs, while the remaining parameters for TDRA can be independently configured for different scheduled PDSCHs or PUSCHs.

The parameters for TDRA may include kO or k2; mapping type; SLIV for each scheduled PDSCH or PUSCH in a slot; number of repetitions for each scheduled PDSCH or PUSCH if repetition is applied for the transmission of PDSCH or PUSCH; number of slots for each scheduled PDSCH or PUSCH if each PDSCH or PUSCH carrying a TB spans more than one slot.

In one example, if only one PDSCH or PUSCH is scheduled with repetition, a single kO or k2 and number of repetitions, and same mapping type can be applied for the scheduled PDSCH or PUSCH, respectively. Note that the kO or k2 can be applied for the first repetition of scheduled PDSCH or PUSCH, respectively. Further, a list of SLIVs can be applied for scheduled PDSCH repetition or PUSCH repetition.

Figure 12 illustrates one example of different SLIVs for scheduled PDSCH with repetition. In this example, different SLIVs are applied for different PDSCH repetitions.

In one example, if repetition is applied for the transmission of more than one PDSCHs or PUSCHs, a single kO or k2, same mapping type and number of repetitions can be applied for all the scheduled PDSCHs or PUSCHs, respectively. Note that the kO or k2 can be applied for the first repetition of first scheduled PDSCH or PUSCH, respectively. In addition, the repetition for the first PDSCH or PUSCH and subsequent PDSCH or PUSCH is scheduled in the adjacent slot after the first repetition of the first PDSCH. Alternatively, subsequent PDSCH or PUSCH repetition may follow right after the first PDSCH or PUSCH repetition, respectively. In this case, consecutive SLIV may be allocated for PDSCH or PUSCH repetition. Further, a list of SLIVs can be applied for scheduled PDSCHs or PUSCHs, where a first SLIV is allocated for the first PDSCH or PUSCH with repetitions, a second SLIV is allocated for the second PDSCH or PUSCH with repetitions, and so on. For example, the list of SLIVs can occupy consecutive symbols.

In another example, if repetition is applied for the transmission of PDSCHs or PUSCHs, a single kO or k2, and a same/common mapping type can be applied for scheduled PDSCHs or PUSCH, respectively. Further, a list of {SLIV, number of repetitions} can be applied for scheduled PDSCHs or PUSCHs, where a first {SLIV, number of repetitions} is applied for the first PDSCH or PUSCH, a second {SLIV, number of repetitions} is applied for the second PDSCH or PUSCH, and so on. Note that in this example, different SLIVs and number of repetitions can be applied for different scheduled PDSCHs or PUSCHs. Alternatively, repetition type A or type B may be applied for the transmission of PDSCHs or PUSCHs with repetition.

Figure 13 illustrates one example of different SLIVs and number of repetitions for scheduled PDSCHs. In the example, starting symbol and length for PDSCH#0 is symbol#2 and 11 symbols, and number of repetitions forPDSCH#0 is 2. In addition, starting symbol and length for PDSCH# 1 is symbol#3 and 11 symbols, and number of repetitions for PDSCH#0 is 3. Further, same SLIV is applied for the repetition for each scheduled PDSCH.

In another example, if each PDSCH or PUSCH carrying a TB spans more than one slot, a single kO or k2 and same mapping type can be applied for scheduled PDSCHs or PUSCH, respectively. Further, a list of {SLIV, number of slots} can be applied for scheduled PDSCHs or PUSCHs, where a first {SLIV, number of slots} is applied for the first PDSCH or PUSCH, a second {SLIV, number of slots} is applied for the second PDSCH or PUSCH, and so on.

Note that for this example, it is assumed that same SLIV is applied for a PDSCH or PUSCH with a TB spanning more than one slot. Similar mechanism can be also applied for the case when consecutive number of symbols in multiple slots is applied for the PDSCH or PUSCH with a TB spanning more than one slot. In this case, only SLIV may be used for PDSCH or PUSCH resource allocation in time, where length of PDSCH or PUSCH may be larger than 14 symbols.

In another embodiment, for each entry of TDRA list, all parameters for TDRA can be independently configured for different scheduled PDSCHs or PUSCHs. In this case, number of scheduled PDSCHs can be derived in accordance with number of TDRA in the entry of TDRA list.

In one example, for each entry of TDRA list, if repetition is applied for each scheduled PDSCH, a list of {kO, mapping type, SLIV, number of repetitions} can be applied for scheduled PDSCHs, where a first {kO, mapping type, SLIV, number of repetitions} is applied for the first scheduled PDSCH, a second {kO, mapping type, SLIV, number of repetitions} is applied for the second scheduled PDSCH, and so on. In another example, if repetition is not applied for each scheduled PDSCH, a list of {k0, mapping type, SLIV} can be applied for scheduled PDSCHs, where a first {k0, mapping type, SLIV} is applied for the first scheduled PDSCH, a second (kO, mapping type, SLIV} is applied for the second scheduled PDSCH, and so on.

AN 1408 may terminate air-interface protocols for the UE 1402 by providing access stratum protocols including RRC, PDCP, RLC, MAC, and LI protocols. In this manner, the AN 1408 may enable data/voice connectivity between CN 1420 and the UE 1402. In some embodiments, the AN 1408 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 1408 be referred to as a BS, gNB, RAN node, eNB, ng-eNB, NodeB, RSU, TRxP, TRP, etc. The AN 1408 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 1404 includes a plurality of ANs, they may be coupled with one another via an X2 interface (if the RAN 1404 is an LTE RAN) or an Xn interface (if the RAN 1404 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 1404 may each manage one or more cells, cell groups, component carriers, etc. to provide the UE 1402 with an air interface for network access. The UE 1402 may be simultaneously connected with a plurality of cells provided by the same or different ANs of the RAN 1404. For example, the UE 1402 and RAN 1404 may use carrier aggregation to allow the UE 1402 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 1404 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 1402 or AN 1408 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 1404 may be an LTE RAN 1410 with eNBs, for example, eNB 1412. The LTE RAN 1410 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 1404 may be an NG-RAN 1414 with gNBs, for example, gNB 1416, or ng-eNBs, for example, ng-eNB 1418. The gNB 1416 may connect with 5G-enabled UEs using a 5GNR interface. The gNB 1416 may connect with a 5G core through an NG interface, which may include an N2 interface or an N3 interface. The ng-eNB 1418 may also connect with the 5G core through an NG interface, but may connect with a UE via an LTE air interface. The gNB 1416 and the ng-eNB 1418 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 1414 and a UPF 1448 (e.g., N3 interface), and anNG control plane (NG-C) interface, which is a signaling interface between the nodes of the NG-RAN1414 and an AMF 1444 (e.g., N2 interface).

The NG-RAN 1414 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 1402 can be configured with multiple BWPs where each BWP configuration has a different SCS. When a BWP change is indicated to the UE 1402, 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 1402 with different amount 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 small traffic load while allowing power saving at the UE 1402 and in some cases at the gNB 1416 A BWP containing a larger number of PRBs can be used for scenarios with higher traffic load.

The RAN 1404 is communicatively coupled to CN 1420 that includes network elements to provide various functions to support data and telecommunications services to customers/subscribers (for example, users of UE 1402). The components of the CN 1420 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 1420 onto physical compute/storage resources in servers, switches, etc. A logical instantiation of the CN 1420 may be referred to as a network slice, and a logical instantiation of a portion of the CN 1420 may be referred to as a network sub-slice.

In some embodiments, the CN 1420 may be an LTE CN 1422, which may also be referred to as an EPC. The LTE CN 1422 may include MME 1424, SOW 1426, SGSN 1428, HSS 1430, PGW 1432, and PCRF 1434 coupled with one another over interfaces (or “reference points”) as shown. Functions of the elements of the LTE CN 1422 may be briefly introduced as follows.

The MME 1424 may implement mobility management functions to track a current location of the UE 1402 to facilitate paging, bearer activation/deactivation, handovers, gateway selection, authentication, etc.

The SGW 1426 may terminate an SI interface toward the RAN and route data packets between the RAN and the LTE CN 1422. The SGW 1426 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 1428 may track a location of the UE 1402 and perform security functions and access control. In addition, the SGSN 1428 may perform inter-EPC node signaling for mobility between different RAT networks; PDN and S-GW selection as specified by MME 1424; MME selection for handovers; etc. The S3 reference point between the MME 1424 and the SGSN 1428 may enable user and bearer information exchange for inter-3 GPP access network mobility in idle/active states. The HSS 1430 may include a database for network users, including subscription-related information to support the network entities’ handling of communication sessions. The HSS 1430 can provide support for routing/roaming, authentication, authorization, naming/addressing resolution, location dependencies, etc. An S6a reference point between the HSS 1430 and the MME 1424 may enable transfer of subscription and authentication data for authenticating/authorizing user access to the LTE CN 1420.

The PGW 1432 may terminate an SGi interface toward a data network (DN) 1436 that may include an application/content server 1438. The PGW 1432 may route data packets between the LTE CN 1422 and the data network 1436. The PGW 1432 may be coupled with the SGW 1426 by an S5 reference point to facilitate user plane tunneling and tunnel management. The PGW 1432 may further include a node for policy enforcement and charging data collection (for example, PCEF). Additionally, the SGi reference point between the PGW 1432 and the data network 1436 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 1432 may be coupled with a PCRF 1434 via a Gx reference point.

The PCRF 1434 is the policy and charging control element of the LTE CN 1422. The PCRF 1434 may be communicatively coupled to the app/content server 1438 to determine appropriate QoS and charging parameters for service flows. The PCRF 1432 may provision associated rules into a PCEF (via Gx reference point) with appropriate TFT and QCI.

In some embodiments, the CN 1420 may be a 5GC 1440. The 5GC 1440 may include an AUSF 1442, AMF 1444, SMF 1446, UPF 1448, NSSF 1450, NEF 1452, NRF 1454, PCF 1456, UDM 1458, and AF 1460 coupled with one another over interfaces (or “reference points”) as shown. Functions of the elements of the 5GC 1440 may be briefly introduced as follows.

The AUSF 1442 may store data for authentication of UE 1402 and handle authentication- related functionality. The AUSF 1442 may facilitate a common authentication framework for various access types. In addition to communicating with other elements of the 5GC 1440 over reference points as shown, the AUSF 1442 may exhibit an Nausf service-based interface.

The AMF 1444 may allow other functions of the 5GC 1440 to communicate with the UE 1402 and the RAN 1404 and to subscribe to notifications about mobility events with respect to the UE 1402. The AMF 1444 may be responsible for registration management (for example, for registering UE 1402), connection management, reachability management, mobility management, lawful interception of AMF-related events, and access authentication and authorization. The AMF 1444 may provide transport for SM messages between the UE 1402 and the SMF 1446, and act as a transparent proxy for routing SM messages. AMF 1444 may also provide transport for SMS messages between UE 1402 and an SMSF. AMF 1444 may interact with the AUSF 1442 and the UE 1402 to perform various security anchor and context management functions. Furthermore, AMF 1444 may be a termination point of a RAN CP interface, which may include or be an N2 reference point between the RAN 1404 and the AMF 1444; and the AMF 1444 may be a termination point of NAS (Nl) signaling, and perform NAS ciphering and integrity protection. AMF 1444 may also support NAS signaling with the UE 1402 over an N3 IWF interface.

The SMF 1446 may be responsible for SM (for example, session establishment, tunnel management between UPF 1448 and AN 1408); UE IP address allocation and management (including optional authorization); selection and control of UP function; configuring traffic steering at UPF 1448 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 1444 over N2 to AN 1408; 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 1402 and the data network 1436.

The UPF 1448 may act as an anchor point for intra-RAT and inter-RAT mobility, an external PDU session point of interconnect to data network 1436, and a branching point to support multi-homed PDU session. The UPF 1448 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 1448 may include an uplink classifier to support routing traffic flows to a data network.

The NSSF 1450 may select a set of network slice instances serving the UE 1402. The NSSF 1450 may also determine allowed NSSAI and the mapping to the subscribed S-NSSAIs, if needed. The NSSF 1450 may also determine the AMF set to be used to serve the UE 1402, or a list of candidate AMFs based on a suitable configuration and possibly by querying the NRF 1454. The selection of a set of network slice instances for the UE 1402 may be triggered by the AMF 1444 with which the UE 1402 is registered by interacting with the NSSF 1450, which may lead to a change of AMF. The NSSF 1450 may interact with the AMF 1444 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 1450 may exhibit an Nnssf service-based interface.

The NEF 1452 may securely expose services and capabilities provided by 3 GPP network functions for third party, internal exposure/re-exposure, AFs (e.g., AF 1460), edge computing or fog computing systems, etc. In such embodiments, the NEF 1452 may authenticate, authorize, or throttle the AFs. NEF 1452 may also translate information exchanged with the AF 1460 and information exchanged with internal network functions. For example, the NEF 1452 may translate between an AF-Service-Identifier and an internal 5GC information. NEF 1452 may also receive information from other NFs based on exposed capabilities of other NFs. This information may be stored at the NEF 1452 as structured data, or at a data storage NF using standardized interfaces. The stored information can then be re-exposed by the NEF 1452 to other NFs and AFs, or used for other purposes such as analytics. Additionally, the NEF 1452 may exhibit an Nnef service- based interface.

The NRF 1454 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 1454 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 1454 may exhibit the Nnrf service-based interface.

The PCF 1456 may provide policy rules to control plane functions to enforce them, and may also support unified policy framework to govern network behavior. The PCF 1456 may also implement a front end to access subscription information relevant for policy decisions in a UDR of the UDM 1458. In addition to communicating with functions over reference points as shown, the PCF 1456 exhibit an Npcf service-based interface.

The UDM 1458 may handle subscription-related information to support the network entities’ handling of communication sessions, and may store subscription data of UE 1402. For example, subscription data may be communicated via an N8 reference point between the UDM 1458 and the AMF 1444. The UDM 1458 may include two parts, an application front end and a UDR. The UDR may store subscription data and policy data for the UDM 1458 and the PCF 1456, and/or structured data for exposure and application data (including PFDs for application detection, application request information for multiple UEs 1402) for the NEF 1452. The Nudr service-based interface may be exhibited by the UDR 221 to allow the UDM 1458, PCF 1456, and NEF 1452 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 1458 may exhibit the Nudm service-based interface.

The AF 1460 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 1440 may enable edge computing by selecting operator/3 ^rd party services to be geographically close to a point that the UE 1402 is attached to the network. This may reduce latency and load on the network. To provide edge-computing implementations, the 5GC 1440 may select a UPF 1448 close to the UE 1402 and execute traffic steering from the UPF 1448 to data network 1436 via the N6 interface. This may be based on the UE subscription data, UE location, and information provided by the AF 1460. In this way, the AF 1460 may influence UPF (re)selection and traffic routing. Based on operator deployment, when AF 1460 is considered to be a trusted entity, the network operator may permit AF 1460 to interact directly with relevant NFs. Additionally, the AF 1460 may exhibit an Naf service-based interface.

The data network 1436 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 1438.

In some embodiments, the protocol processing circuitry 1514 may include one or more instances of control circuitry (not shown) to provide control functions for the transmit/receive components.
