User equipment initiated beam managment

Abstract

Methods and apparatus are provided for UE-initiated beam management in a wireless network. The UE receives, from a base station, one or more configuration parameters including an indicated unified TCI state. The UE determines a current beam as a selected QCL source associated with the indicated unified TCI state, and determines a measurement reference resource for each of one or more new beams. The UE performs beam measurements of the current beam and the one or more new beams. Based on the beam measurements, the UE generates a UE-initiated beam report when a first quality of at least one of the one or more new beams becomes a threshold value better than a second quality of the current beam. The UE transmits the UE-initiated beam report to the base station.

Description

USER EQUIPMENT INITIATED BEAM MANAGMENTTECHNICAL FIELD

[0001] This application relates generally to wireless communication systems, including wireless communication systems with beam management.BACKGROUND

[0002] Wireless mobile communication technology uses various standards and protocols to transmit data between a base station and a wireless communication device. Wireless communication system standards and protocols can include, for example, 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) (e.g., 4G), 3GPP New Radio (NR) (e.g., 5G), and Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard for Wireless Local Area Networks (WLAN) (commonly known to industry groups as Wi-Fi®).

[0003] As contemplated by the 3GPP, different wireless communication systems' standards and protocols can use various radio access networks (RANs) for communicating between a base station of the RAN (which may also sometimes be referred to generally as a RAN node, a network node, or simply a node) and a wireless communication device known as a user equipment (UE). 3GPP RANs can include, for example, Global System for Mobile communications (GSM), Enhanced Data Rates for GSM Evolution (EDGE) RAN (GERAN), Universal Terrestrial Radio Access Network (UTRAN), Evolved Universal Terrestrial Radio Access Network (E-UTRAN), and / or Next- Generation Radio Access Network (NG-RAN).

[0004] Each RAN may use one or more radio access technologies (RATs) to perform communication between the base station and the UE. For example, the GERAN implements GSM and / or EDGE RAT. the UTRAN implements Universal Mobile Telecommunication System (UMTS) RAT or other 3GPP RAT, the E-UTRAN implements LTE RAT (sometimes simply referred to as LTE), and NG-RAN implements NR RAT (sometimes referred to herein as 5G RAT, 5G NR RAT, or simply NR). In certain deployments, the E- UTRAN may also implement NR RAT. In certain deployments, NG-RAN may also implement LTE RAT.

[0005] A base station used by a RAN may correspond to that RAN. One example of an E- UTRAN base station is an Evolved Universal Terrestrial Radio Access Network (E- UTRAN) Node B (also commonly denoted as evolved Node B, enhanced Node B, eNodeB, or eNB). One example of an NG-RAN base station is a next generation Node B (also sometimes referred to as a g Node B or gNB).14861-9813-4229'1 P68913WO1

[0006] A RAN provides its communication services with external entities through its connection to a core network (CN). For example, E-UTRAN may utilize an Evolved Packet Core (EPC) while NG-RAN may utilize a 5G Core Network (5GC).

[0007] Frequency bands for 5G NR may be separated into two or more different frequency ranges. For example. Frequency Range 1 (FR1) may include frequency bands operating in sub-6 gigahertz (GHz) frequencies, some of which are bands that may be used by previous standards, and may potentially be extended to cover new spectrum offerings from 410 megahertz (MHz) to 7125 MHz. Frequency Range 2 (FR2) may include frequency bands from 24.25 GHz to 52.6 GHz. Note that in some systems, FR2 may also include frequency bands from 52.6 GHz to 71 GHz (or beyond). Bands in the millimeter wave (mmWave) range of FR2 may have smaller coverage but potentially higher available bandwidth than bands in FR1. Skilled persons will recognize these frequency ranges, which are provided by way of example, may change from time to time or from region to region.BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

[0016] Various embodiments are described with regard to a UE. However, reference to a UE is merely provided for illustrative purposes. The example embodiments may be utilized with any electronic component that may establish a connection to a network and is configured with the hardware, software, and / or firmware to exchange information and data with the network. Therefore, the UE as described herein is used to represent any appropriate electronic component.

[0017] Beam management focuses on optimization and control of radio beams for enhancing transmissions between a base station and a UE. Appropriate beam management enhances transmission and signal quality by managing interference, focusing signal energy, and allowing more UEs to be served through efficient use of resources.

[0018] NR beam management can be divided into components such as beam measurement and reporting (from the UE), beam indication, and beam failure recovery. For example, beam management can include actively scanning beams to find the strongest beam signal, beam refinement to narrow and optimize a beam direction, and beam measurement and reporting where UEs measure signal quality and report back to the base station. Adjustments can then be made at the base station based on real-time conditions.

[0019] In terms of beam indication, 3GPP Release 15 and 16 support a legacy Transmission Configuration Indicator (TCI) framework where different physical (PHY) channels / signals have different beam indication mechanisms, including Radio Resource Control (RRC)-based. Medium Access Control (MAC)-Control Element (CE)-based. and Downlink Control Information (DCI)-based. Downlink (DL) channels / signals use TCI states, while uplink (UL) channels / signals use spatial relations. 3GPP Release 17 and 18 introduce a unified TCI (uTCI) framework, where a single set of TCI states indicates the beams for multiple channels / signals for both DL and UL. There are two modes in this framework. The first mode. "Joint TCI," applies one joint TCI to both UL and DL channels / signals. The second mode, "Separate TCI," uses separate TCI states for DL and UL beam indications, with DL TCI for DL beam indication and UL TCI for UL beam indication.

[0020] Two schemes of TCI State indication are supported. Scheme 1 involves common TCI indication for multiple channels and signals, where the common TCI is applied to dedicated Physical Downlink Control Channel (PDCCH), Physical Downlink Shared Channel (PDSCH), Physical Uplink Control Channel (PUCCH), and Physical Uplink Shared Channel (PUSCH). Additionally, the common TCI can be optionally applied to aperiodic34861-9813-4229'1 P68913WO1channel state information (CSI)-reference signal (RS) for beam management (BM) and CSI. as well as Sounding Reference Signal (SRS) for codebook-based (CB), non-codebook-based (NCB), angle-based (AS), and BM purposes. Whether this common TCI is applied to the channels and signals is configured by RRC signaling. Scheme 2 involves dedicated TCI indication for one channel or signal, applied to signals where the common TCI indication (Scheme 1) is not used. This scheme reuses 3GPP Release 16 signaling to provide the TCI indication for such channels and signals.

[0021] For the 3GPP Release 17 unified TCI framework, in the "Joint TCI" mode, up to 128 TCI states can be configured in the dl-OrJointTCI-StateList-rl7 per PDSCH-Config. In the "Separate TCI" mode, for DL unified TCI, up to 128 TCI states can be configured in the dl-OrJointTCI-StateList-r!7 per PDSCH-Config, and for UL unified TCI, up to 64 TCI-UL states can be configured in the ul-TCI-StateList-r!7 per BWP-UplinkDedicated.

[0022] Beam management presents several challenges during execution, such as handling UE mobility, managing transmissions, and the complexity of implementation. To mitigate certain such challenges. UE-initiated / event-driven beam management can be implemented for reducing overhead and / or latency. For instance, within a unified TCI schema including legacy CSI measurement and reporting configuration frameworks (and targeting FR2 and Single-Transmission Reception Point (sTRP) with intra-cell and inter-cell beam management), two aspects may be considered: (a) UL signaling content and procedures required for UE-initiated / event-driven beam reporting to facilitate fast beam switching, and (b) UL signaling medium / container considering the UE-initiated / event-driven nature of the UL transmission (e.g., designed for the purpose of beam reporting).

[0023] Aspects and implementations of the present disclosure addresses the above and other challenges by providing solutions to support UE initiated beam management. In some embodiments, a method is provided for facilitating measurement resource configuration and content reporting at the UE. For example, in one embodiment, a method is provided in which a UE receives, from a base station in a wireless network, one or more configuration parameters including an indicated unified TCI state. The UE then determines a current beam as a selected quasi co-located (QCL) source associated with the indicated unified TCI state, and determines a measurement reference resource for each of one or more new beams. The UE then performs beam measurements of the current beam and the one or more new beams. Based on the beam measurements, the UE generates a UE-initiated beam report when a first quality of at least one of the one or more new beams becomes a threshold value better than a44861-9813-4229'1 P68913WO1second quality of the current beam. The UE then transmits the UE-initiated beam report to the base station.

[0024] Example embodiments for measurement resource configuration of a current beam

[0025] To enhance UE-initiated / ev ent-driven beam reporting, trigger event detection for beam reporting may at least support an event (referred to as “Event-2”) that is triggered when the quality of at least one new beam, such as Layer 1 reference signal received power (RSRP), becomes a threshold value better than the current beam.

[0026] In some embodiments, to support UE-initiated beam management for the measurement resource configuration to configure the current beam, when the indicated unified TCI state is configured with two QCL sources, the current beam is determined as the QCL source with QCL-TypeD. For example, the QCL source can be one of the following: CSLRS for Tracking Reference Signal (TRS), where CSI-RS for TRS is a CSI-RS resource in a Non-Zero Power (NZP) CSI-RS Resource Set (NZP-CSI-RS-ResourceSet) configured with a higher layer parameter (e.g., trs-Info); or CSI-RS for beam management, where CSI- RS for beam management is configured as a CSI-RS resource in an NZP-CSI-RS- ResourceSet configured with higher layer parameter (e.g., repetition).

[0027] For example, within a method for a UE to perform UE-initiated beam management in a wireless network, an indicated unified TCI state can be configured with two QCL sources. The method can include selecting one of the two QCL sources comprising a QCL- TypeD for the selected QCL source as the current beam. The selected QCL source may be one of a first CSI-RS for TRS or a second CSI-RS for beam management.

[0028] In other embodiments, to support UE-initiated beam management for the measurement resource configuration to configure the current beam, when the indicated unified TCI state is configured with one QCL source, the current beam is determined as the QCL source associated with the indicated unified TCI state, which may be a CSI-RS for TRS. For example, within a method for a UE to perform UE-initiated beam management in a wireless network, an indicated unified TCI state can be configured with a single QCL source, such as a CSI-RS for TRS. The method can include selecting the CSI-RS for TRS for the selected QCL source as the current beam.

[0029] In other embodiments, to support UE-initiated beam management for the measurement resource configuration to configure the current beam, when the indicated unified TCI state is configured with either one or two QCL sources, and one QCL source is selected (e g., with QCL-TypeD being selected as described above in the case of two QCL sources), the QCL source of the selected QCL source can be used as the current beam. In54861-9813-4229'1 P68913WO1this case, the current beam may be one of a CSI-RS for beam management, a CSI-RS for TRS, or a synchronization signal block (SSB).

[0030] For example, within a method for a UE to perform UE-initiated beam management in a wireless network, an indicated unified TCI state can be configured with a single QCL source or two QCL sources. The method can include selecting a first QCL source from among the single QCL source or two QCL sources, and selecting a second QCL source of the first QCL source for the selected QCL source as the current beam.

[0031] Example embodiments for measurement resource configuration of new beams

[0032] In certain embodiments, to support UE-initiated beam management for the measurement resource configuration when configuring one or more new beams, the measurement reference resources can be explicitly or implicitly configured. For example, in one embodiment, the network explicitly configures a set of measurement reference resources. The network may configure the set of measurement reference resources in a corresponding CSI report setting (CSI-ReportConfig) or outside the CSI report setting (i.e., the same set of measurement reference resources is used for all UE-initiated beam management, at least in the same component carrier (CC)). In another embodiment, the UE implicitly derives the measurement reference resource as being an RRC-configured list of unified TCI states or as being a MAC-CE activated list of unified TCI states.

[0033] Within a method for a UE to perform UE-initiated beam management in a wireless network, determining the measurement reference resource for each of one or more new beams can include receiving, from the base station, an explicitly configured set of measurement reference resources. Alternatively, as mentioned, determining the measurement reference resource for each of the one or more new beams can include implicitly deriving the measurement reference resource for each of the one or more new beams from an RRC configured list of unified TCI states or a MAC-CE activated list of unified TCI states.

[0034] In some embodiments, to support UE-initiated beam management for the measurement resource configuration to configure one or more new beams when the network explicitly configures a set of measurement reference resources, a subset of the measurement reference resources can be further selected. For example, a MAC-CE can be used to select a subset of the measurement reference resources. As another example, a subset of the measurement reference resources can be selected based on the unified TCI states, where only the reference resource in the RRC-configured list of unified TCI states is selected or only the reference resource in the MAC-CE activated list of unified TCI states is selected.64861-9813-4229'1 P68913WO1

[0035] Accordingly, within a method for a UE to perform UE-initiated beam management in a wireless network, determining the measurement reference resource for each of one or more new beams can include receiving, from the base station, an explicitly configured set of measurement reference resources and selecting a subset of the set of measurement reference resources.

[0036] In certain embodiments, to support UE-initiated beam management for the measurement resource configuration when configuring both new beam(s) and a current beam, the new beam(s) and the current beam are configured to have the same type (e.g., either all SSBs or all CSI-RSs). For example, it is not allowed to have a mix of SSBs and CSI-RSs as the new beam(s) and the current beam. Accordingly, within a method for a UE to perform UE-initiated beam management in a wireless network, when making a comparison to determine when the first quality of the at least one of the one or more new beams becomes the threshold value better than the second quality of the current beam, the one or more new beams can be the same type as the current beam.

[0037] In other embodiments, to support UE-initiated beam management for the measurement resource configuration when configuring new beam(s) and a current beam, the new beam(s) and the current beam can have different types. For example, some reference resources for the new7beam(s) and / or the current beam can be SSBs, while others can be CSI-RSs. To compare the measurement results (i.e., RSRP between SSB and CSI-RS), the RSRP measurement performed on CSI-RS is scaled by a power control offset value (e.g., powerControlOffsetSS). The powerControlOffsetSS, which is the assumed ratio of NZP CSI-RS Energy Per Resource Element (EPRE) to Synchronization Signal (SS)ZPhysical Broadcast Channel (PBCH) block EPRE, is configured in NZP-CSI-RS-Resource (e.g., as specified in 3GPP TS38.214). Therefore, in some embodiments, RSRPSSB can be compared with RSRPCSI-RS - powerControlOffsetSS, where RSRPSSB is the RSRP measurement of the corresponding SSB, and where RSRPCSI-RS the RSRP measurement of the corresponding CSI-RS.

[0038] Accordingly, within a method for a UE to perform UE-initiated beam management in a wireless network, when the current beam is a different type than at least one of the one or more new beams, and when making the comparison to determine when the first quality of the at least one of the one or more new beams becomes the threshold value better than the second quality of the current beam, the method can include scaling a RSRP measurement of the current beam or the new beam by a power control offset value.74861-9813-4229'1 P68913WO1

[0039] Example embodiments for report content

[0040] In some cases, for UE-initiated beam management, N > 1 beams can be reported (e.g., by the UE to the base station). The network can also configure the UE to report the current beam together with new (N > 1) beams. In alternate embodiments, the network can configure the UE to not report the current beam with the new beams.

[0041] In some cases, to support UE-initiated / event-driven beam reporting, regarding UL signaling contents of Ll-RSRP report depending on Event-2, in a report instance, at least one option is supported wherein N > 1 beams are reported in the report instance. At least one of the N-reported beam(s) satisfy the condition of Event-2. A value of N (e.g., up to a threshold limit), can be configured by the base station (e.g.., gNB).

[0042] In some cases, regarding the Ll-RSRP report format for UE-initiated / event-driven beam reporting, depending on Event-2, for a report instance where N > 1 beams are reported, the RRC can enable or disable whether the current beam is always reported. For example, when enabled by RRC signaling, the current beam plus N beams from the measurement reference signals for new beams are reported. Note that in this example the reported current beam is not counted in the N reported beams. When disabled by RRC signaling, only N beams can be reported.

[0043] FIG. 1 A illustrates an example CSI format for a first example report 102 from a UE to a base station, in accordance with embodiments described herein. In the illustrated example, the first example report 102 includes resource indicator 104A (shown as Resource Indicator #1), resource indicator 104B (shown as Resource Indicator #2),..., resource indicator 104N (shown as Resource Indicator #N), RSRP value 106 (shown as RSRP #1), and differential RSRP value 108 A (shown as Differential RSRP #2) through differential RSRP value 108N (shown as Differential RSRP #N).

[0044] In some embodiments, to support UE-initiated beam management and report N > 1 beams when the network does not configure the UE to report the current beam, the illustrated CSI format can be used, where resource indicator #i (where i = 1, 2, ... , N) is the indicator of the reported resource. The bit- width of the resource indicator is [log2(KRs)], where KRS is the total number of new beams configured for the UE. Thus, the UE may report N > 1 new beams of the KRS total new beams, among which at least one beam satisfies the event trigger.

[0045] In some embodiments, for either the CS1-RS or SSB, the ordering or mapping of each CSI-RS / SSB to the resource indicator is based on the corresponding CSI-RS or SSB index. For example, for the SSB the resource indicator (e.g., #1, #2, #3, etc.) is ordered84861-9813-4229'1 P68913WO1based on the SSB index, and for CSI-RS the resource indicator (e.g., #1, #2, #3, etc.) is the NZP-CSI-RS-Resourceld. Alternatively, the ordering can be based on the order in which the resource is configured in the list of the measurement resource. In embodiments when both the CSI-RS and SSB are configured for the same UE-initiated beam reporting, the CSI-RS resource can be ordered before the SSB. Alternatively, in other embodiments the SSB can be ordered before the CSI-RS.

[0046] In some embodiments, an RSRP #i, i = 1, and / or a set of differential RSRP #i, i = 2 ,... , N corresponds to the resource indicator #i. For example, the RSRP value 106 (RSRP #1) corresponds to the resource indicator 104A (Resource Indicator #1), The differential RSRP value 108A (Differential RSRP #2) corresponds to the resource indicator 104B (Resource Indicator #2),..., and differential RSRP value 108N (Differential Indicator #N) corresponds to the resource indicator 104N (Resource Indicator #N).

[0047] Differential encoding can be used to encode RSRP. In some embodiments, resource indicator 104A (Resource Indicator #1) is assumed to have the largest RSRP, and its RSRP value 106 (RSRP #1) is encoded with more bits (e.g.. 7 bits). Resource indicator #i, i = 2 . ... , N have RSRPs lesser than (e.g., not larger than) the RSRP of resource indicator #1. Thus, RSRPs of resource indicators #i, i = 2 , ... , N are reported as differential RSRPs #i, i = 2 , ... , N that are encoded as the difference between RSRP #1 and measured RSRPs #i, i = 2 , ... , N. Differential RSRPs #i, i = 2 , ... . N can be encoded with fewer bits (e.g., 4 bits each), which reduces overhead.

[0048] Accordingly, within a method for a UE to perform UE-initiated beam management in a wireless network, generating the UE-initiated beam report can include including, in the UE-initiated beam report, a first list of resource indicators for N number of reported resources, where N is a value greater than or equal to one configured by the wireless network, and where a first resource indicator in the first list corresponds to a first of the one or more new beams with a largest RSRP measurement of the beam measurements. The method can further include, in the UE-initiated beam report, a second list of RSRP values ordered according to the first list, where a first RSRP value in the second list corresponds to the largest RSRP measurement and subsequent RSRP values in the second list comprise differential RSRP values compared to the largest RSRP measurement.

[0049] FIG. IB illustrates an example CSI format for a second example report 110 from a UE to a base station, in accordance with other embodiments described herein. As illustrated, the second example report 110 adds a resource indicator 104N+1 (shown as Resource Indicator #N+1) and a differential RSRP value 108N+1 (shown as Differential RSRP #N+1)94861-9813-4229'1 P68913WO1to the first example report 102 shown in FIG. 1A so as to report N+l (N > 1) beams when the network configures the UE to report the current beam. The resource indicator 104N+1 includes the resource indicator for the current beam, and the differential RSRP value 108N+1 is the differential RSRP value of the current beam as compared to the RSRP value 106 (i.e.. the largest measured RSRP value).

[0050] As discussed above, when the current beam is not reported, or when the current beam is included in the KRS number of configured new beams, then the bit-width of the resource indicator is [log2(KRs)]. However, when the second example report 110 includes the current beam and the current beam is not included in the KRS number of configured new beams, then the bit-width of the resource indicator is [log2(KRs+l)]. Further, when the current beam is not included in the KRS number of configured new beams, the first or last index can be assigned to the current beam (i.e., index 0 or index KRS). In certain embodiments, however, the resource indicator 104A cannot correspond to the current beam (because it is for the largest RSRP that triggered the event). Rather, the current beam is reported as one of the resource indicators #i, where i = 2, 3, ... , N+l.

[0051] FIG. 1C illustrates an example CSI format for a third example report 112 from a UE to a base station, in accordance with other embodiments described herein. As illustrated, the third example report 112 adds the differential RSRP value 108N+1 (shown as Differential RSRP #N+1) to the first example report 102 shown in FIG. 1 A so as to report N+l (N > 1) beams when the network configures the UE to report the current beam. In this example, the differential RSRP value 108N+1 is appended at the end of the N > 1 beam report when the network does not configure the UE to report a resource indicator for the current beam (e.g., the network already knows which is the current beam and that the differential RSRP value 108N+1 corresponds to the current beam). In certain embodiments, when the current beam is included in the KRS number of configured new beams, then the UE is not expected to report the current beam as one of the resource indicators #i, where i = 1, 2. 3, ... , N+1.

[0052] In some embodiments, to support UE-initiated beam management on multiple component carriers (CCs), the network can configure new beams and the current beam for each CC. For example, a UE-initiated beam report may include two parts. A first part (Part 1) can include a list of CCs on which the event is triggered. In one embodiment for Part 1. reporting can be accomplished as a C-bit bitmap, where C is the total number of CCs on which the network configures the UE-initiated beam management. In such a bitmap, a bit can be set to T when the UE reports the beam measurement for the corresponding CC in a104861-9813-4229'1 P68913WO1second part (Part 2). In another embodiment for Part 1. the UE can first report the total number of CCs that have the event triggered, and then the index of each CC that has the event triggered. In Part 2, the UE sequentially reports the beam measurement for each CC in the list of CCs on which the event is triggered. The content of the beam measurement for each CC may follow embodiments for reports as disclosed herein. Note that the size of Part 2 may depend on the content of Part 1. For uplink control information (UCI) size reservation, a hypothesis of the number of CCs can be assumed to determine the size of Part 2. Such a number can be either hardcoded in the specification or configured by the network via RRC.

[0056] In certain embodiments of the method 200. the indicated unified TCI state is configured with a single QCL source comprising a channel state information (CSI)- reference signal (RS) for tracking reference signal (TRS), and the method further includes selecting the CSI-RS for TRS for the selected QCL source as the current beam.114861-9813-4229'1 P68913WO1

[0057] In certain embodiments of the method 200. the indicated unified TCI state is configured with a single QCL source or two QCL sources, and the method further comprises: selecting a first QCL source from among the single QCL source or the two QCL sources; and selecting a second QCL source of the first QCL source for the selected QCL source as the current beam.

[0058] In certain embodiments of the method 200, determining the measurement reference resource for each of the one or more new beams comprises receiving, from the base station, an explicitly configured set of measurement reference resources.

[0084] Example architectures and devices

[0085] FIG. 4 illustrates an example architecture of a wireless communication system 400, according to embodiments disclosed herein. The following description is provided for an example wireless communication system 400 that operates in conjunction with the LTE system standards and / or 5G or NR system standards as provided by 3GPP technical specifications.

[0086] As shown by FIG. 4. the wireless communication system 400 includes UE 402 and UE 404 (although any number of UEs may be used). In this example, the UE 402 and the UE 404 are illustrated as smartphones (e.g., handheld touchscreen mobile computing devices connectable to one or more cellular networks), but may also comprise any mobile or non-mobile computing device configured for wireless communication.

[0087] The UE 402 and UE 404 may be configured to communicatively couple with a RAN 406. In embodiments, the RAN 406 may be NG-RAN, E-UTRAN, etc. The UE 402 and UE 404 utilize connections (or channels) (shown as connection 408 and connection 410, respectively) with the RAN 406, each of which comprises a physical communications interface. The RAN 406 can include one or more base stations (such as base station 412 and base station 414) that enable the connection 408 and connection 410.

[0088] In this example, the connection 408 and connection 410 are air interfaces to enable such communicative coupling, and may be consistent with RAT(s) used by the RAN 406, such as, for example, an LTE and / or NR.

[0089] In some embodiments, the UE 402 and UE 404 may also directly exchange communication data via a sidelink interface 416. The UE 404 is shown to be configured to access an access point (shown as AP 418) via connection 420. By way of example, the connection 420 can comprise a local wireless connection, such as a connection consistent with any IEEE 802. 11 protocol, wherein the AP 418 may comprise a Wi-Fi® router. In this example, the AP 41 may be connected to another network (for example, the Internet) without going through a CN 424.174861-9813-4229'1 P68913WO1

[0090] In embodiments, the UE 402 and UE 404 can be configured to communicate using orthogonal frequency division multiplexing (OFDM) communication signals with each other or with the base station 412 and / or the base station 414 over a multicarrier communication channel in accordance with various communication techniques, such as. but not limited to, an orthogonal frequency division multiple access (OFDMA) communication technique (e.g., for downlink communications) or a single carrier frequency division multiple access (SC- FDMA) communication technique (e.g., for uplink and ProSe or sidelink communications), although the scope of the embodiments is not limited in this respect. The OFDM signals can comprise a plurality of orthogonal subcarriers.

[0091] In some embodiments, all or parts of the base station 412 or base station 414 may be implemented as one or more software entities running on server computers as part of a virtual network. In addition, or in other embodiments, the base station 412 or base station 414 may be configured to communicate with one another via interface 422. In embodiments where the wireless communication system 400 is an LTE system (e.g., when the CN 424 is an EPC), the interface 422 may be an X2 interface. The X2 interface may be defined between two or more base stations (e.g., two or more eNBs and the like) that connect to an EPC. and / or between two eNBs connecting to the EPC. In embodiments where the wireless communication system 400 is an NR system (e g., when CN 424 is a 5GC), the interface 422 may be an Xn interface. The Xn interface is defined between two or more base stations (e.g., two or more gNBs and the like) that connect to 5GC, between a base station 412 (e.g., a gNB) connecting to 5GC and an eNB, and / or between two eNBs connecting to 5GC (e.g., CN 424).

[0092] The RAN 406 is shown to be communicatively coupled to the CN 424. The CN 424 may comprise one or more network elements 426, which are configured to offer various data and telecommunications services to customers / subscribers (e.g., users of UE 402 and UE 404) who are connected to the CN 424 via the RAN 406. The components of the CN 424 may be implemented in one physical device or separate physical devices including components to read and execute instructions from a machine-readable or computer-readable medium (e.g., a non-transitory machine-readable storage medium).

[0093] In embodiments, the CN 424 may be an EPC, and the RAN 406 may be connected with the CN 424 via an SI interface 428. In embodiments, the SI interface 428 may be split into two parts, an SI user plane (Sl-U) interface, which carries traffic data between the base station 412 or base station 414 and a serving gateway (S-GW), and the SI -MME interface.184861-9813-4229'1 P68913WO1which is a signaling interface between the base station 412 or base station 414 and mobility management entities (MMEs).

[0094] In embodiments, the CN 424 may be a 5GC, and the RAN 406 may be connected with the CN 424 via an NG interface 428. In embodiments, the NG interface 428 may be split into two parts, an NG user plane (NG-U) interface, which carries traffic data between the base station 412 or base station 414 and a user plane function (UPF), and the SI control plane (NG-C) interface, which is a signaling interface between the base station 412 or base station 414 and access and mobility management functions (AMFs).

[0095] Generally, an application server 430 may be an element offering applications that use internet protocol (IP) bearer resources with the CN 424 (e.g., packet switched data services). The application server 430 can also be configured to support one or more communication services (e.g., VoIP sessions, group communication sessions, etc.) for the UE 402 and UE 404 via the CN 424. The application server 430 may communicate with the CN 424 through an IP communications interface 432.

[0096] FIG. 5 illustrates a system 500 for performing signaling 534 between a wireless device 502 and a network device 518, according to embodiments disclosed herein. The system 500 may be a portion of a wireless communications system as herein described. The wireless device 502 may be, for example, a UE of a wireless communication system.
