Figure I Illustrates a network environment 100 in accordance with some embodiments. The network environment 100 may include a HE 104 and a plurality of access nodes (ANs), for example, AN 108, AN 112, and AN 1 16, [0031] Each AN may provide one more serving ceils to provide cellular service to connected UEs For example, AN 108 may provide serving cell 110, AN 112 may provide serving cell 114, and AN 116 may provide serving cell 1 18, While one serving cell is shown per AN, in various embodiments each AN may provide a plurality of serving cells including a primary cell (PCeSl) and one or more secondary cells (SCelis), In some embodiments, the serving cells may have carrier frequencies located in an unlicensed portion of the spectrum and the network environment may operate, at least partially, in an NR-U system.

[0032] The UE 104 may include a radio resource control (RRC) state machine that performs operations related to a variety of ERC procedures including, for example, paging, RRC connection establishment, RRC connection reconfiguration, and RRC connection release. The ERC state machine may be implemented by protocol processing circuitry, see, for example, baseband circuitry 710 and 810 of Figures 7 and 8.

[0033] The .RRC slate machine may transition the UE into one of a number of RRC states

(or“modes*’} including, for example, a connected state (RRC connected), an inactive state (RRC inactive), and an idle state (RRC idle). The UE 104 may start in RRC idle when it first camps on a 5G cell, for example, cell 110. This may be after the HE 104 has been switched on or after an inter-system cell reselection from a Long Term Evolution (LTE) cell.

[0034] To engage in active communications, the RRC state machine may transition the UE 104 from RRC idle to RRC connected by performing an RRC setup procedure to establish a logical connection 120, for example, an RRC connection 120, with the AN 108. In RRC connected, the UE 108 may be configured with at least one signaling radio hearer (SRB) for signaling (for example, control messages) with the AN 108; and one or more data radio bearers (DRBs) for data transmission.

[0035] When the UE is less actively engaged in network communications, the RRC state machine may transition the UE 104 from RRC connected to RRC inactive using an RRC release procedure. The RRC inactive state may allow the UE 104 to reduce power consumption as compared to RRC connected, but wifi still allow the UE 104 to quickly transition back to RRC connected to transfer application data or signaling messages.

[0036] While in RRC idle or RR.C inactive, the RRC state machine may manage mobility by performing a cell reselection in the event signal metrics from the serving cell 1 10 fell below predetermined thresholds. I» general, the U E 104 may measure signal metrics from a plurality of neighbor cells and select one or more of the neighbor cells as candidates for the reselection. Candidates of equal priority may be ranked based on signal metrics such as, tor example, reference signal receive power (RSP) reference signal received quality (RSRQ), signal-to-iBierforence plus noise ratio (S1NR), etc. The UE 104 may select one of the candidate cells, for example, cell 1 14 or 116, as a target eel! for cell reselection. If one or more signal metrics from the target cell are over a predetermined threshold for a predetermined; period of time, the UE 104 may complete the cell reselcetion,

[0037] For MR-th when the FCell Is operating In an unlicensed band, the cell reseleetsuo from RRC idle or ERG inactive may he applied by the UE 104 in the unlicensed band. In some instances, the neighbor cells operating in the unlicensed hand may he ffexu different operatorsbelonging to different public land mobile networks (PLMNs), This may present a challenge for the UE 104 to have robust cell reselection iu unlicensed bands. For example, if the UE 104 rcselccts to a cel! that belongs to a different PLMN in which the HE 104 is not registered, fee cell reselcetion would fell. Accordingly, various embodiments describe techniques to improve success rates fot cell reselection in NR--U.

[0038] In some embodiments, the UE 104 may engage in a two-step (or '‘stage' } ceil reselcetion procedure for NR-U. As will be described in more detail below, the second stage, which is optional in some embodiments, may invol ve checking the PEMN associated willy target cell before performing a resdeetion to the target cell These embodiments may improve a success rate far Ulfeai.de cell re-seiection in an unlicensed band, even in the presence of uncoordinated neighboring cells belonging to different PLMHs being in within that baud.

[0039] Aspects of the embodi ments deseri bed herein may be implemented through devices or components performing openftion ffewsMgoriihmie structures. Figures 2 - 6 illustrate some operation flows/algorithmic structures in accordance with some embodiments. Some or all of the details pf Figures 2 - 6 may be performed by a UE, for example, UE 104 of Figure 1 or UEs 701 a or 701 h of Figure ?; components, for example, baseband circuitry 810/910 of Figures 8/9, or radio front end modules 815/915 of Figures 8/9; or processors 1012/1014 and roemory/storage devices 1050 of Figure 10.

[0040] Figure 2 illustrates an operation flow/algorithrnic structure 200 for a two-stage cell reselection to improve cell resefeetion performance In accordance some embodiments. [0041] The operation ffow/a!ftorithmle structure 200 includes a fast stage 204 and a secant! stage 208, Generally, the first stage 204 involves selection of a target cell while the second stage 2Q8 involves a pro- check of the PLMN information of the target cell,

[0042] in the first stage 204, at 208, the Operation ilowfolgorithmic structure 200 may include detecting and measuring a set of neighboring cell candidates. in various embodiments, the tiE may rhea sore or otherwise obtain measurament quality metrics for assessing neighbor ceils for cdi reselection, These measurement quality metrics may include any combination of, ibr example, RSRP, RSRQ, Si NR, etc,

[0043] in some embodiments, tire RRC layer may direst lower layers to . perform the detecting and measuring of tire neighbor eel! candidates. For example, a Layer 1 (LI ) of the UE 104 may perform Li measurements on synchtouixaiion signal/phy steal broadcast channel (SS/PBCH) blocks of neighbor cells Because reselection is to change a serving ceil, the Li measurements may he cell-level measurements, rather than beam-level measurements.

[0044] The cell-level measurements may he, derived Ifom one or more beam level measurements based on parameters hmadcast within a system information block (SIB) 2 or SIB 4 of source ceil for purposes of cdi reselection. These parameters may include a number of $$- blocks to average, ttm0$~8locksToAvemge, which may range ftom 2 ~ I d, for example, and absolute threshold SS-blqeks consolidation, absIhreshSS-BtoehC^moHdatum, which may be a value range from O - 127 snapped onto an RSRP or RSRQ value. The cell level measurement may , he defined as a linear average of up xm/SS-BfoeksToAventge beams that have the strongest measurement results that exceed ihf -absTkfeahSS-B!oekiCQnsolidaUon threshold. If less than nr0fi$S~&l(wksToAvemgeb®&iXi$ exceed the absThreshSS ' BhcksCms&Maikm threshold, only the beams that exceed the threshold utay be averaged. If no beams exceed the threshold, the cell level result may be set equal fo She strongest beam level result,

[0045] In some embodiments. If the UE 104 is not configured with nmfSS-

SlackslhAverage and ahsThreshSS-BlocbCmsoBdaibn parameters, the !J E 104 may use tho measurement from the strongest beam as the ceil level measurement

[0046] The first stage 204 may also include, at 216, preselecting foe target ceil based on the measurement metrics. In various embodiments, the preselection of the target cell may include a preliminary deeisfon of determining that reselection from the etmohfsemng ceil is to occur and further deterommg which of a number of candidate neighbor cells will be die target of the cell rese!ection process {hereinafter "target cel ),

[0047] in some embodiments, the eelHevei LI measurements collected in 212 may be filtered at Layer 3 {1,3} to detect one or moi'e events related: to comparing serving or target cell measurements to various thresholds. These events may include an A2 event, which may fee triggered when the serving ceil becomes worse than a threshold * an A3 event, which may fee triggered when a neighboring cell becomes better titan a special cell (for example, the FCell of a master cell group or a secondary cell group) by an offset; or an,A4 event, which may bo triggered when a neighboring cell becomes better than a threshold,

[0048] The second stage 208 may Include, at 220, decoding a master information block (MIB) and a system information block (SIB) 1 of the target cell and extracting Pi, Mbs information of the target cell. The target cell may broadcast system information using the MIB and a series of SlBs. Minimum system information (MSI) may be transmitted in the MIB and the SIB 1 , with the SIB I. specifically carrying remaining minimum system information (RMSi), The remaining SIB s, for example SIBs 2 - 9, may carry other system information (OSI)

[0049] The MIB may he transmitied using the BCCB logical channel, BCM transport ehatme!, and PBCH physical channel. The SIB 1 may he transmitted using the BCCH logical ehanne, the DL-SCH transport chasm e!, and the FDSCH physical channel,

[0050] The BE 104 may acquire the MIB based on information provided by current serving cell (in, for example, a S!B4 transmission) regarding global synchronization ehanne! numbers (GSCN) of neighbor cells. In embodiments in which the UE 104 does not have a current serving cell !he MIB may be acquired by scanning a set of GSCNs and discovering an SS/PBCB block. The MIB may be found directly on the PBCH without relying on any resource allocations on the PDCCH, The UE 194 may decode foe MIB to discover information regarding a control resource set (CORBSET) and search space used by the PDCCH when making: a resource allocation for the SIB ! in the FDSCH, In this manner, the UE 104 may determine the signaling parameters (for example, time offset, frequency (for example, component earner), transmission mode, etc,) for receiving the SIB I,

[0051] Upon receiving and decoding the SIB I , the UE 104 may extract the PLMN information from the decoded SIB ! bits. The PLMN information may be included in a eel! access related mfbrm&llon, ceiMccessliehfedlnfb^ information element (IE) in the SIB 1 , The ceilAccessRiilaiedinfb IE may Include FLMN identities associated with the broadcasting cell. Each FLMN identity may he defined by its mobile coosty code (MCC) and mobile network code (MNC). individual FLMN identities may be associated wh!h a tracking arw code (TAC). RAN area code (RANAC), eel! identity. and: dag to indicate whether or not the cell is reserved for operator use.

[0052] The UE 1.04 may compare die FLMN information from the SIB ! of the target cell to PLAIN information associated with the serving cell. In some embodiments, the FLMN associated with the serving cell may have been previously acquired from a S1B.1 transmitted by The serving gNB.

[0053] ifithe UB 104 determines, at 228, that a FLMN identity from thoPLMN information of the target eel! matches, for example, is identical to, & FLMN identity from the FLMN information of the source cell, the operation fiow/algonthmic structure 2:00 may advance to applying a ceil reseieetiPrrto the target cell at 232. hi sonie embodlnienift, this may include, among oilier things, the HE transmitting a random access channel to the: gNB of the target cell to access the target cell and establish an RRC connection,

[0054] lfthe UE 104 determines, at 228, that a FLMN identity from the FLMN information of the target cell does not match, for example, is not identical to, a FLMN identity from the FLMN information of the soured cell, The operation f!ow/aigoriilnntc structure 200 may revert to the first stage 204, for example, detecting: and measuring a set of neighboring cell candidates at 212, In seme embodiments, if the measurement metrics obtained at 212 have not expired, the operation flow/aigotiihmle structure 200 may revert back to preselecting another target cell at 216 based on the previously obtained information.

[0055] Figure 3 illustrates an operation i!ovNalgoriihmic structure 300 for a one- or twestage cell reselection to improve cell reselection m accordance with some embodiments.

[0056] The operation fiow/algorithmk structure 3QQ may include a first stage 304 and a second stage 308, The second stage 308 may be an option that will be performed In some scenarios.

[0057] Similar to like-named operations of the first stage 204, the first stage 304 may

Include detecting and measuring a set of neighboring cell candidates at 312 and preselecting the target cel! based on the measurement metrics at 316. [0058] Following the first stage 304, the operation flow/aigorithmic structure 300 may include, at 31 $, decoding the M1B of the target cell and extracting SJB1 configuration. As discussed above, the MIB may include information related to the SIB I configuration including, tor example, timing and other location information of the SIB! transmissions.

[0059] At 322, the operation flow/aigorithmic structure 322 may include determining whether the SlB l is co-locafed with a DRS of the target cell. The DRS may correspond to the SS/PBCH blocks that the UB 104 processes for the purposes oh tor example, acquiring the ,M IB, performing cell measurements and discovery, etc. If the SlB l is colocated with the DRS, for example, m the DRS block: or within a predefined time interval front the DRS block, the UE 104 may also proceed with SIB 1 decoding quickly slier having received the DRS from the associated candidate cell. Thus, if it is determined af 322, that the SIB! is codocated wills the DRS of the target ceil, the operation Row/atgoriihmk structure 300 may proceed to the second stags 308,

[0060] The second stage 308 may include decoding the SlBl of the target eel! and extracting FLMN mlrirmaiion of the target cell, at 320, and comparing: the extracted FLMN information of the target cell with the FLMN information of the source: cell at 324, Following extraction ofthe PLMN information, the UE may determine whether a FLMN ID associated with target ceil Is the same as: FLMN ID associated with the source cell at 328 and either advance to applying the cell reseiectfon at 332 or loop back to operations of the first stage 304. The operations at 320, 324, and 328 may be similar to respective operations described in 220, 224, and 228 of Figure 2,

[0061] If the SIB! is not co-loeared with the DRS of the target cell, for example, if the

SlBl allocation is further than a predefined timing threshold from the DF$ block, if may be that the added assurance of She pre-selection FLMN cheek may not be worth the extra time: needed to also decode the SSBL Thus, in some embodiments, if it is determined, at 322, that the SlBl Is not eo-loeated with the DRS of the target cell, the operation flow/aigorithmic structure 300 may skip the second stage 308 to bypass the extm time needed to decode the S!B l and proceed directly to applying the reseiection at 332. In the event that the target cell Is not associated with a compatible FLMN, the resdection may fail after the target cell does not respond to the UB ' s random access channel transmission. After which, the UE may attempt reseleefion with another candidate ceil,

[0062] Figure 4 illustrates an operation flow/aigorithmic structure 400 lor a two-stage cell reseiection in accordance with some embodiments, [0063] The operation fiow/aigomkmic struclure 400 may include, at 404, measuring oneø* more qualify metrics for a set of candidate cells that are candidates for eel! re-selection in oae or more unlicensed bands of an NR-U network. The one or more qualify metrics, as discussed above, may include, for example, one or more of an RSRP, an R8RQ, or an SiNR.

[0064] The operation ftow/aigorithone structure 400 may further include, at 408, selecting a first candidate ceil of the set of candidate cells based on foe measured one or mom quality metrics. For example, the candidate cell with the quality metrics that indicate the highest quality among the set of candidate cells may be selected,

[0065] The operation fiow/a!gonforok structure 400 may further include, at 412:, determining a first PLMN associated with the first candidate cell. The first PLMN may be determined by decoding SIR ! of the first candidate cell to extract PLMN Information in some embodiments, the !JB may decode an MΪB of the first candidate cell, and may decode: the SIR bused ort information in the MIR as discussed above,

[0066] The operation ffow/aigoriihrnie structure 400 may forther include, at 416, comparing the first PLMN a current PLMN of a source ceil in some embodiments, the target or source cell may be associated with more than one PLMN, For example, a cell may be associated with a plurality of PLIvINs and the cell may broadcast a list of the IDs of the PLMNs in Us S IS I transmissions. In these embodiments, foe comparing at 416 may include determining whether any PLMNs associated with foe first candidate cell is also associated with the source cell

[0067] The operation fiow/algoritbmie structure 400 may further include, at 420, determining whether to perform eel! re-selection from the source ceil to the first candidate cell based on the comparison at 4 lb. For example, cell re-selection may be perfonned If the first PLMN is foe same as the current FLMN (or if a PtMN associated with the first candidate cell is also associated with the source cell), if the first PtMN k different .from foe current PLMN for if a PtMN associated with the first candidate ceil is not also associated with the source cell), the cell re-selection to the first candidate cell may not be perforated, instead, the UB may select a second candidate ceil from foe set of candidate cells (lor example, based on the measured one or more quality metrics and/or updated measurements of the one or mom quality metrics). The UE 104 may then repeat the operations of 412, 416, and 420 for the second candidate ceil.

[0068] Figure 5 illustrates an operation fiow/algontemie structure 500 in accordance wi th some embodmients.

[0069] lift some embodiments, the operation flow/ algorithmic structure $#0 may be initiated upon an Initial determination Awarding the stains: of a current serving cell For example, if a quality of the current serving cell as measured by one or more quality metrics, fails below a predetermined threshold for a predetermined period of time, some or ail die operation flow/algon&mlc structure may be implemented by a UE.

[0070] Once initiated, die operation ilow/algornhmk structure 50b may Include, at 504. selecting a target eel! front one or more candidate cells based on a measured quality metric. As discussed above, the UE may measure signals, for example, SS/PBCiH signals, from various neighbor ceils to determine qual ity metrics related to, or otherwise based on, R.SE.P, RSRP, SINR, etc. Eased ou these metrics, the UE may select one target cell from one or more candidate cells for cell reseleetion.

[0071] The operation ilow/slgoritboue structure 500 may further include, at $08, decoding a MJB to extract SIB I information related to die target cell, The MIB, which may be transmitted in the FBCH of the target cell, may provide information related to configuration of the SIB (1st example, the time/ffequeocy resources on which the SIB I is transmitted),

[0072] The operation dow/aigorifbroie structure 500 may further include, at 512, determining whether to perform a cell reseleetion from (he source cell to the target call based on the SIB I information.

[0073] In some embodiments, the SIB I information may simply be location information

(for example, time allocation information) of die SIBl . This location information may allow the UE to determine whether or not the B!Bl is co~ioeated with a DBS (or SS/P8CM) of the target coll. To sletermiue whether the SIBl is co-Ioeated with the DBS, the UE may compare Che SIB 1 time allocation information with the DBS time allocation information, if a difference between the two time allocations is below a predefined threshold, the SIB! may be considered to be oo-locafed with the 1>R.S. The UE may either pre-check PLMN information or proceed directly to eel! reselection based on the determination of whether the SIB! is co-located with the DBS, This may be similar to That described above with respect to operation 322 of Figure 3,

[0074] In other embodiments, the SIB ? information upon which the UE bases determination at 512 may include additional/altersstive ίhίohhMίoh snob as, but not limited to, FLMN information extracted from the $181. transmission itself. This may he the ease if fee UE performs a two-stage cell reselection procedure (as shown in Figure 2, for example) or determines that tire SIB] is eo-loeaied wife the DBS (or SS/PBCH) in the optional two-stage cell reselection procefenc (as shown in Figure 3, for example).

[0075] Thus, in some embodiments, if the LIB detects a first condition (tor example, SIBI not co-Ioeated wife DBS or both fee target and source cells are associated wife common PLMN) it may proceed to apply preselection to fee target cell. If the first condition relates to the co-ioeation of fee SIBI /DBS and is not 1st some cases, if fee first condition is not presenfeased on system information, feat a first condition is (for example, th. The first conditio» may be t and may apply a reselection to a target cell

I n some embodiments, the procedure may be initiated, ifafe an RRC idle or RRC inactive state, when the UB detects that one or more quality metrics associated wife a serving cell are below a predetermined threshold, in some embodiments, fee metrics may also need to be below the threshold for a predetermined period of lime for the LB to initiate fee ceil reseleetion procedure·.

[0078] The operation flow/algofitftmic strtseture 600 may further include, at 600, selecting a target cell for reseiection. The selection of the target cell may be done in a manner similar to the operations described above with respect to 216 of Figure 2, for example.

The network condition detected at 616 may be the son-codocafiowof the SIBI and a DRS of fee target cell. In other embodiments, the network condition detected at 616 may be that both the source cell and fee target cell are associated wife a common FLMN. This may be detected by comparing target cell FLMN information (acquired from the SIB 1) wife source ceil PLMN information.

As used herein, the terms“access node,”“access point,” or the like may describe equipment that provides the radio baseband functions lor data and/or voice eanueoiivrty between a network and one or more users. These access nodes can he referred to as BS, gNBs, RAN nodes, oNBs, NodeBs, RSUs, TfixFs or TRPs, and so forth, and can comprise ground stations (e,g,, terrestrial access points) or satellite stations providing coverage within a geographic area (e,g„ a ceil ) . As used herein, the term“NG RAN node” or the tike may refer to a RAH node 71 1 that Operates in ad NR or 5G system 700 (for example a gNB), and the term“E-UTRAN node” or the like may refer to a

Aecordmg to various embodiments, tbe RAN nodes 71 1 may be implemented as one or swore of a dedicated physical device sueh as a macroedl base stahon, and/or a low power (LP) base station for providing ferntoee!Is, picocelis ©f other like cells .having smaller coverage areas, smaller user capacity, or higher bandwidth compared t© macrocells,

In vehicle-to-everything (Y2X) scenarios one or more of the RAN nodes 71 1 may he or set as a road-side unit (RSU l An RSU may refer t© arty transportation infrastructure entity used for V23£ communications, An RSU may be implemented in or by a suitable RAN node or a stationary (or relatively stationary) UB, where an RSU implemented in or by a UE may be referred to as a“UE-type RSUT an RSU implemented in orby as eNB may be referred to as an "WB-type RSUT an RSU implemented in or by 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 70S (vU.Es), The RSU may also include internal data storage ehcuitry to store intersection map geometry, traffic statistics, media, as well as applications/software to sense and control ongoing vehicular and pedestrian Raffle. The RSU may operate on the 5,9 GHz Direct Short Range Communications (DSRC) band to provide very low latency communications required lor high speed events, such as crash avoidance, traffic warnings, and the like. Additionally or alternatively, the ESU may operate on the cellular V2X band to provide the aforementioned low latency communications, as well as other cellular communications services, Additionally or alternatively, the RSU may operate as a Wi-Fi hotspot (2.4 GHz band) and/or provide connectivity to one or more cellular networks to provide uplink and downlink communications. The computing deviee(s .) and some or all of the radioffequency eircoitty of the RSU may he packaged in a weatherproof enc losure sui table for outdoor installation, and may include a network interface controller to provide a wired connection :{c,g. » Ethernet) to a: traffic signal controller and/or a backhaul network

[0090] Any of fee RAN nodes ?! 1 can terminate: the air interface protocol and can be fee first point of contact for the UEs ?0!. in some embodiments, any of the RAN nodes 71 I can fulfill various logical functions fer the RAN 710 including, but not limited: to, radio network controller CRNC) functions such as radio bearer management, uplink and downlink dynamic radio resource management: and data packet scheduling, and mobility management.

[0091] In embodiments, the UEs 701 can be configured to communicate using OFDM communication signals with each other or wife any of the RAN nodes 71 1 over a mnlticarrier communication channel in accordance with various communication techniques, such as, but not limited to, an OFDMA communication technique (c.g., for downlink communications) or a SC- FDMA communication technique (e,g,, for uplink and FroSe of sideiink comnumiciitfons), although foe: scope of the embodiment is not limited in this respect. The OFDM; signals can comprise a plurality of orthogonal subcamers.

[0092] In some embodiments, a downlink resource grid ears be used for downlink transmissions from any of the RAN nodes 73 1 to foe IJEs 701 , while uplink transmissions can utilize similar techniques. The grid can he a iime-lrequency grid, called a resource grid or iime- frequeney resource grid, which is the physical resource in the downlink in each slot Such a time- frequency plane representation is a common practice for orthogonal frequency division mtdfrpfox {OFDM} systems, which makes it intuitive for radio resource allocation, Each column and each row of the resource grid corresponds to one OFDM symbol and one OFDM subcarrier, respectively. The duration of the resource grid in the time domain corresponds to one slot in a radio frame. The smallest hme~freque«cy unit in a resource grid is denoted as a resource element. Each resource grid comprises a number of resource blocks, which describe the mapping of certain physical channels to resource elements. Each resource block comprises a collection of resource elements; in the frequency domain, this may represent the smallest quantity of resources that currently can he allocated. There are several different physical downlink channels that are conveyed using such resource blocks,

[0094] To operate in the unlicensed spectrum, for example, in NR-IJ systems, the UEs 701 and foe RAN nodes 711 may operate using LAA, eLAA, and/or leLAA mechanisms, lu these implementations, the UEs 701 and the RAN nodes 711 may perform, one or mom known medium- sensing operations and/or carrier-sensing operations in order to determine whether one or more channels in the unlicensed spectrum is unavailable or otherwise occupied prfor to transmitting in the unlicensed spectrum. The medium/oamer sensing operations may be performed according to a listsn-before-ialk (LSI ' ) protocol,

[0095] As discussed above, LBT is a mechanism whereby equipment (for example, UEs 7(11 RAN nodes: 71 1 , etc.) senses a medium (for example, a channel of earner frequency) and transmits when ihe medium is sensed to be idle (dr when a specific channel, in the medium is sensed to be Unoceupied), The medium sesteing operation may include clear channel assessment (CCA), which uuitees at least energy detection (ED) to determine the presence or absence of other signals OH a channel in order to determine if a channel is occupied or clear, This LET mechanism allows cellnlar/LAA networks to coexist with incumbent systems in the unlicensed spectrum and with other LAA networks. ED may include sensing RF energy across an intended transmission band for a period of time and comparing the sensed RF energy to a predefined or configurer! threshold.

[0096] The RAM nodes 71 1 may be configured to communicate with one another via interface 712, The interface 712 may be an Xn interface 712 The Xn interface is defined between two or more RAN nodes 7 P (e,g., two or more, gNBs and the like) that connect to 5GC 720, between a RAN node ? !

The Xn-C may provide management and error handling functionality, functionality to manage the Xn-C interface; mobility support lor UE 701 in a connected mode (e.g,, CM- CQNXECTED} including functional! iy to manage the UE mobility for connected mode between one or more RAN nodes 71 1 , The mobility support may include context transfer from an old (source) serving RAM node 71 i to new (target) serving RAN node 71 1; and control of user plane tunnels between old (source) serving RAN node 71 1 to new (target) serving RAN node 70, A protocol stack of the Xn-li may include a transport network layer built on internet Protocol (IF) transport layer, and a OTP-U layer os top of a UDF and/or IF layer(s) to carry user plane PDUs. The Xn-C protocol stack stay include as application layer signaling protocol (referred io as X» Application Protocol (Xn-AP)} and -a transport network layer that is built on SCTF. The SCTP may be os top of an IF layer, and may provide the guaranteed delivery of application layer messages. hi the transport IF layer, point- io-polnt transmission Is used to deliver foe signaling FBlls. to other implementations, the Xn-U protocol stack and/or the Xn-C protocol stack may be same or similar to the user plane atid/or control plane protocol staek(s) shown and described herein,

In some embodiments, network function virtualization (NPV) may pc utilised to virtualize any or all of the above-described network node functions via executable mstnsetkms stored in one or more computer-readable storage mediums (described in further detail below). A logical instantiation of the CM 720 may be referred to as a network slice, and a logical instantiation of a portion of the CN 720 may be referred· to as a network suh-sllee, NFV architectures and inirastrnetnffis may be used to virtualise one or «tore network functions, alternatively performed by proprietary hardware, onto physical resources comprising a combination of industry-standard server hardware, storage hardware, or switches. In other words, NFV systems can be used to execute virtual or .^configurable implementations of one or more EPC eompanems/furseiions.
