DOWNLINK CONTROL INFORMATION (DCI) BASED BEAM INDICATION FOR NEW RADIO (NR)
CROSS REFERENCE TO RELATED APPLICATIONS

FIELD
[0002] Various embodiments generally may relate to the field of wireless communications, and in particular, to the field of communication in a cellular network compliant with one of more Third Generation Partnership Project (3GPP) specifications.
BACKGROUND
[0003] In Release 15 (Rel-15) and Release 16 (Rel-16) NR MIMO, downlink (DL) beam indication for physical downlink shared channel (PDSCH) is performed via transmission configuration indicator (TCI) state indication, wherein radio resource control (RRC) configures a set of TCI states to the user equipment (UE), a medium access control (MAC) control element (CE) (MAC-CE) command is used to activate at most 8 TCI states and when supported, a downlink control information (DCI) can indicate one of the 8 activated TCI states via a 3-bitmap. For physical downlink control channel (PDCCH) the TCI state is activated via MAC-CE only. Further for uplink, physical uplink control channel (PUCCH) spatial relation information is activated via MAC-CE, and for sounding reference signal (SRS,) spatial relation information is configured per resource and indicated by the SRS resource indicator (SRI) field in DCI. For semi-persistent sounding reference signal (SRS), MAC-CE activation of spatial relation information is also supported. In order to unify the beam indication framework, the concept of TCI state for uplink or a joint uplink/downlink TCI has been agreed to be supported for Rel-17 NR. See Chairman's Notes, 3GPP RAN WGl#102-e, August 2020. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0012] 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).
[0013] One goal in Rel-17 is to achieve a unified beam management framework for the UL and DL wireless links. In Rel-15 and Rel-16 provide TCI states for only the DL links. As noted previously, in order to unify the beam indication framework, the concept of TCI state for uplink or a joint uplink/downlink TCI has been agreed to be supported for Rel-17 NR. See Chairman's Notes, 3GPP RAN WGl#102-e, August 2020. In this case, however, if both downlink (DL) and uplink (UL) beam indication is performed via TCI state indication, a more unified TCI state activation framework is needed.
[0014] Embodiments herein may relate to the Rel-17 work related to supporting enhancements on MIMO beam management.
[0015] The UE is to recognize the TCI states from an information element in a radio resource control (RRC) message to the UE, which configures TCI states for the UE, including beam information, source reference signals, target reference signals, etc. In this manner, a UE configured with TCI states by the RRC message would recognize details of a TCI state during activation. The UE may be configured with M number of beams, for example 64, or 128 beams, but, as things stand, can switch between at most N beams, for example 8 beams, corresponding to 8 TCI states.
[0016] Activation of a TCI state at the UE (informing the UE that it should expect to use for communication one of more TCI states from the TCI states configured by the RRC message) may be implemented by a MAC CE command as noted above. The MA CE element may be sent in the form of data in a physical downlink shared channel (PDSCH).
[0017] After activation, where multiple TCI states are indicated to the UE (configured by the RRC message and activated by way of the MAC CE command), a DCI as noted above may be used to tell the UE which channel or channels to apply the one or more activated TCI states to. [0018] In one embodiment, UL TCI states and joint uplink/downlink states are to share the same pool of TCI state IDs with DL TCI states. Thus, according to this embodiment, legacy DL TCI states are to remain and be used, and the same manner of identifying them may be used to identify TCI states for UL TCI states and for joint uplink/downlink TCI states. According to this embodiment, a message to the UE, or information element to the UE, that contains these TCI states would be similar for DL, UL and joint uplink/downlink TCI states, and whether the TCI state applies to DL, UL or join uplink/downlink may be determined through other information, such as by other content to the UE. Thus, other indication mechanisms, such as other signaling (possibly in a same message including the TCI state ID, or in a different message) or such as by way of a rule, may be used to allow the UE to know which one of DL, UL or joint uplink/downlink applies to a specified TCI state ID.
[0019] Thus, when the UE receives the MAC CE (where more than one TCI states are to be activated), the MAC CE may, according to an embodiment, be the same as a legacy MAC CE, and the UE would know which of DL,UL or joint uplink/downlink links the activation of the MAC CE would apply to.
[0020] In one embodiment, the UL TCI state configuration optionally includes parameters for PUCCH, which parameters can be applicable when the TCI state is activated for PUCCH. As an example, the UL TCI state can include information regarding power control, and SRS (such as SRS ID and UL BWP). Thus, power control parameters may be associated with a TCI state according to some embodiments. For example, the UL TCI State may include the following:
UplinkTCI-State ::= SEQUENCE { tci-Stateld TCI-Stateld, pucch-PathlossReferenceRS-ld PUCCH-PathlossReferenceRS-ld, OPTIONAL, pO-PUCCH-ld PO-PUCCH-ld, OPTIONAL, closedLoopIndex ENUMERATED { iO, il } OPTIONAL, qcl-Typel QCL-Info, qcl-Type2 QCL-Info OPTIONAL, - Need R
}
QCL-Info ::= SEQUENCE { cell ServCelllndex OPTIONAL, - Need R bwp-ld BWP-ld OPTIONAL, - Cond CSI-RS-lndicated referencesignal CHOICE { csi-rs NZP-CSI-RS-Resourceld, ssb SSB-lndex, srs SEQUENCE { resourceld SRS-Resourceld, uplinkBWP BWP-ld
} qcl-Type ENUMERATED {typeA, typeB, typeC, typeD},
}
[0021] In one embodiment, the UL TCI state indication or the joint uplink/downlink TCI state indication for TCI state IDs activated by MAC-CE can be performed through DCI signaling. By "indication" or "indicate" in the context of a TCI state, what is meant herein is that a TCI state is activated (such as via MAC CE) and indicated for application by a UE. For this purpose, a new DCI format may, according to an embodiment, be designed. A DCI may contain the following information:
• Channels and reference signals to which the indicated TCI state is applicable;
• TCI State ID of the UL, DL or joint uplink/downlink TCI state indication which is applicable to the channels/reference signals indicated by the bitmap;
• Serving Cell ID and BWP ID where the indicated TCI state is applicable; and/or
• Optionally additional fields related to specific channels and reference signals are also present, as shown in Figure 1.
[0022] Referring now to Fig. 1, a DCI format 100 according to a first embodiment is shown. As seen in Fig. 1, the DCI format 100 is to indicate a TCI state by way of a TCI State ID field 104. Conditionally present fields 106 may include, as noted above, PUCCH related fields 108 including information regarding power control 110, and SRS information 112 (such as SRS ID). The conditionally present fields 106 may also include PDCCH CORESET ID, and other PUCCH related fields 108, such as PUCCH resource ID, and closed loop index. The PUCCH related fields 108 may be present optionally, if not already configured such as by way of a TCI state. Thus, parameters such as power control may be associated with a TCI state even if not included in the DCI that indicates TCI state to the UE. The new DCI format 100 may also include serving cell ID, DL BWP ID, UL BWP ID.
[0023] Referring still to Fig. 1, with N activated TCI states where N is an integer (and recall that N may be activated by way of MAC CE), the DCI, such as DCI 100, may indicate the TCI state to be used. The bitmapl02 indicates the channels will are to use that one TCI state. Thus, a bit in the 6 bit bitmap relating to any of the channels could be turned on (set to 1 for example) to indicate that a corresponding channel for that bit is to use the TCI state indicated by the DCI in the TCI state ID field. The bits may relate to physical downlink control channel (PDCCH), physical downlink shared channel (PDSCH), physical uplink control channel (PUCCH), physical uplink shared channel (PUSCH), SRS and channel state information reference signal (CSI-RS), as shown. When all 6 bits are turned on, the TCI state indicated will apply to all channels to be used by the UE. Thus, in one embodiment, when all fields of the 6-bit bitmap in Fig. 1 are set to l's, it indicates that the signaled TCI state is a common beam indication applicable to all the channels for both transmit (Tx) and receive (Rx) beams. In one example of this embodiment, the TCI state ID can correspond to only a joint uplink/downlink TCI state when common beam indication is used.
[0024] In another embodiment, the bitmap indicating which channels the TCI state applies to can be less than 5 bits, that is, it may be only 3-bits and contain only indications for UL channels and reference signals (RSs) e.g., PUCCH, PUSCH and SRS.
[0025] In a second embodiment, as shown in the example DCI format 200 of Fig. 2, the DCI indication can contain different TCI state IDs 204 which are applicable to the channels indicated by the bitmap 202. This DCI format can therefore indicate more than one TCI state to a UE. Here TCI state IDs can correspond to UL, DL or joint uplink/downlink TCI states, and TCI states are applied, in order, to the channels indicated by the bit map 202. For example, if the channel bitmap 202 indicates 101000, the TCI state ID 1 is applicable to PDCCH at bit 1, and TCI state ID 2 (the next available indicated TCI state) is applicable to PUCCH. Thus, the bitmap decides which TCI state applies to which channel.
[0026] In one embodiment, when the bit map is all Is, the first TCI State ID is applied to all channels as common beam indication.
[0027] In another embodiment, the DCI can also be applicable to a group of UEs. In this example, the indication DCI is transmitted in a group-common PDCCH monitored in a common search space, and has its CRC scrambled by a group common radio network temporary identifier (RNTI) e.g., G-RNTL In this option the indication DCI can be of the form of either single TCI activation as shown in Fig. 1 or multiple TCI state activation as shown in Fig. 2.
[0028] In one option of the above embodiment, the activation DCI may correspond to the DCI 300 of Fig. 3 for group common activation for multiple users appended as shown in Fig. 3. In DCI 300, a format 100 or 200 similar to the one shown in either of Fig. 1 or Fig. 2, respectively, may be used for any of the UE fields UE1-UEN shown in Fig. 3.
[0029] For a group-common DCI as shown in the example of Fig. 3, UEs can be configured by UE-specific RRC signaling or another group common DCI to identify their respective positions in the DCI and select the correct TCI activation. In this option, the activation DCI can also be sent over a PDCCH monitored in a common search space (CSS) and the DCI is scrambled by a group-common RNTI. Alternately, PDCCH can also be monitored in a UE specific search space (USS) with the DCI scrambled by C-RNTL
[0030] In one embodiment, an UL beam indication or TCI state activation, separate from DL beam indication, may be performed using a joint DL/UL TCI state which contains quasi co-located (Q.CL) source reference signals for both DL and UL beams.
[0031] In one example, a common UL beam "indication" (via MAC CE and DCI when more than one TCI state is activated to the UE, and via only MAC CE when a single TCI state is activated to the UE) is a common beam indication in that it applies to all UL channels.
[0032] In one embodiment, the UL beam indication via joint DL/UL TCI states is performed by activating a set of N joint DL/UL TCI states from the list of RRC configured TCI states, and the TCI state to be applied is signaled to the UE via a DL DCI e.g., DCI format 1_1, or 1_2, through the TCI field when tci-PresentlnDCI is enabled. [0033] Additionally, for UL separate beam indication, the UE may be signaled dynamically, through a new field in DCI to only apply the UL QCL source and ignore the configured DL QCL source in the joint TCI state.
[0034] In another example, the configured TCI state will be such that the DL QCL source will be restricted to remain identical to the current DL QCL source e.g., the DL beam is unchanged and only the UL source RS is updated.
[0035] In another embodiment, the UL QCL source RS can be indicated by a joint DL/UL TCI state signaled to the UE via an UL-beam indication DCI e.g., format 0_l, 0_2. The UE in this case updates only the UL beam indicated by the joint TCI state and ignores the DL QCL source.
[0036] In one embodiment, the UL beam indication or TCI state indication, separate from DL beam indication, is performed using a separate UL TCI state which contains QCL source reference signals for only UL. In one example, the beam indication is a common beam indication which applies to PUCCH/PUSCH/SRS. In one embodiment, the separate UL beam indication via UL TCI state activation may be signaled to the UE via the TCI field in a DL DCI format e.g., 1_1, 1_2. [0037] In one example, the UL TCI shares the same pool of TCI states with DL and/or joint DL/UL TCI and the UE can discern that the signaled TCI is applicable to UL beam indication based on the TCI state index of the activated TCI state list, where the TCI states are activated via a MAC- CE. A bitwidth in DCI, for example of 8 bits of codepoints, for example bits 0 to 7, may be used to indicate a TCI index that informs the US that TCI state in the DCI applies to UL beams. By decoding TCI index in the DCI, the UE may thus know which codepoints apply to UL and which to DL.
[0038] In the alternative, the UE may implicitly know from the activation MAC CE whether the TCI state indicated is to be for DL or for UL or for join.
[0039] In one embodiment, when the UE is indicated by a DCI to use a TCI state for DL or UL, or DL and UL, the UE may not apply the indicated TCI state before an acknowledgement for DCI decoding has been transmitted. Thus, in this embodiment, the UE will not apply the TCI state indicated to it by the DCI before it has transmitted an acknowledgement (ACK) for the DCI to the gNB. In one example, the TCI state can be a joint DL/UL TCI state which applies to all DL and UL channels/RSs. In another example, the TCI state can be a DL only or UL only TCI state. In another embodiment, the DCI indicating the TCI state can be a scheduling DCI and the acknowledgement of the DCI decoding can be the acknowledgement of the PDSCH or PUSCH scheduled by the DCI. In one example, the UE can transmit the acknowledgement for decoding of the beam indication and/or scheduling DCI using the beam corresponding to the already activated TCI state, or to the transmit spatial filter without applying the TCI state update indicated in the DCI. In one embodiment, the indicated TCI state can be applied X OFDM symbols after transmission of the acknowledgement of the decoding of the beam indication DCI wherein, where the value of X is a UE capability and can be signaled to the gNB. In one example, the value of X can be 28 OFDM symbols, while in another example, the value of X can 1 OFDM symbol.
[0040] In another embodiment, the DCI can be a scheduling DCI which has additionally a separate acknowledgement transmitted independently of the acknowledgment of the PDSCH or PUSCH scheduled by the DCI. In yet another embodiment, the UE may use the TCI state indicated by the TCI state activation DCI immediately on reception of such DCI. In one example, if the DCI is a scheduling DCI, the UE uses the indicated TCI state for reception of the PDSCH or PUSCH scheduled by the DCI. In another example, the UE also uses the TCI state indicated in the DCI to transmit the acknowledgement for the decoding of the DCI.
[0041] Systems and Implementations
[0042] Figs. 4-6 illustrate various systems, devices, and components that may implement aspects of disclosed embodiments described above and below in relation to Fig. 5.
[0043] Fig. 6 illustrates a network 400 in accordance with various embodiments. The network 400 may operate in a manner consistent with 3GPP technical specifications for LTE or 5G/NR systems. However, the example embodiments are not limited in this regard and the described embodiments may apply to other networks that benefit from the principles described herein, such as future 3GPP systems, or the like.
[0044] The network 400 may include a UE 402, which may include any mobile or non- mobile computing device designed to communicate with a RAN 404 via an over-the-air connection. The UE 402 may be communicatively coupled with the RAN 404 by a Uu interface. The UE 402 may be, but is not limited to, a smartphone, tablet computer, wearable computer device, desktop computer, laptop computer, in-vehicle infotainment, in-car entertainment device, instrument cluster, head-up display device, onboard diagnostic device, dashtop mobile equipment, mobile data terminal, electronic engine management system, electronic/engine control unit, electronic/engine control module, embedded system, sensor, microcontroller, control module, engine management system, networked appliance, machine-type communication device, M2M or D2D device, loT device, etc.
[0045] In some embodiments, the network 400 may include a plurality of UEs coupled directly with one another via a sidelink interface. The UEs may be M2M/D2D devices that communicate using physical sidelink channels such as, but not limited to, PSBCH, PSDCH, PSSCH, PSCCH, PSFCH, etc.
[0046] In some embodiments, the UE 402 may additionally communicate with an AP 406 via an over-the-air connection. The AP 406 may manage a WLAN connection, which may serve to offload some/all network traffic from the RAN 404. The connection between the UE 402 and the AP 406 may be consistent with any IEEE 802.11 protocol, wherein the AP 406 could be a wireless fidelity (Wi-Fi®) router. In some embodiments, the UE 402, RAN 404, and AP 406 may utilize cellular-WLAN aggregation (for example, LWA/LWIP). Cellular-WLAN aggregation may involve the UE 402 being configured by the RAN 404 to utilize both cellular radio resources and WLAN resources.
[0047] The RAN 404 may include one or more access nodes, for example, AN 408. AN 408 may terminate air-interface protocols for the UE 402 by providing access stratum protocols including RRC, PDCP, RLC, MAC, and LI protocols. In this manner, the AN 408 may enable data/voice connectivity between CN 420 and the UE 402. In some embodiments, the AN 408 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 408 be referred to as a BS, gNB, RAN node, eNB, ng-eNB, NodeB, RSU, TRxP, TRP, etc. The AN 408 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.
[0048] In embodiments in which the RAN 404 includes a plurality of ANs, they may be coupled with one another via an X2 interface (if the RAN 404 is an LTE RAN) or an Xn interface (if the RAN 404 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.
[0049] The ANs of the RAN 404 may each manage one or more cells, cell groups, component carriers, etc. to provide the UE 402 with an air interface for network access. The UE 402 may be simultaneously connected with a plurality of cells provided by the same or different ANs of the RAN 404. For example, the UE 402 and RAN 404 may use carrier aggregation to allow the UE 402 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.
[0050] The RAN 404 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 PCel Is/Scel Is. Prior to accessing the unlicensed spectrum, the nodes may perform medium/carrier-sensing operations based on, for example, a listen-before-talk (LBT) protocol.
[0051] In V2X scenarios the UE 402 or AN 408 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.
[0052] In some embodiments, the RAN 404 may be an LTE RAN 410 with eNBs, for example, eNB 412. The LTE RAN 410 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.
[0053] In some embodiments, the RAN 404 may be an NG-RAN 414 with gNBs, for example, gNB 416, or ng-eNBs, for example, ng-eNB 418. The gNB 416 may connect with 5G- enabled UEs using a 5G NR interface. The gNB 416 may connect with a 5G core through an NG interface, which may include an N2 interface or an N3 interface. The ng-eNB 418 may also connect with the 5G core through an NG interface, but may connect with a UE via an LTE air interface. The gNB 416 and the ng-eNB 418 may connect with each other over an Xn interface.
[0054] 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 414 and a UPF 448 (e.g., N3 interface), and an NG control plane (NG-C) interface, which is a signaling interface between the nodes of the NG-RAN414 and an AMF 444 (e.g., N2 interface).
[0055] The NG-RAN 414 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. [0056] 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 402 can be configured with multiple BWPs where each BWP configuration has a different SCS. When a BWP change is indicated to the UE 402, 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 402 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 402 and in some cases at the gNB 416. A BWP containing a larger number of PRBs can be used for scenarios with higher traffic load.
[0057] The RAN 404 is communicatively coupled to CN 420 that includes network elements to provide various functions to support data and telecommunications services to customers/subscribers (for example, users of UE 402). The components of the CN 420 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 420 onto physical compute/storage resources in servers, switches, etc. A logical instantiation of the CN 420 may be referred to as a network slice, and a logical instantiation of a portion of the CN 420 may be referred to as a network sub-slice.
[0058] In some embodiments, the CN 420 may be an LTE CN 422, which may also be referred to as an EPC. The LTE CN 422 may include MME 424, SGW 426, SGSN 428, HSS 430, PGW 432, and PCRF 434 coupled with one another over interfaces (or "reference points") as shown. Functions of the elements of the LTE CN 422 may be briefly introduced as follows.
[0059] The MME 424 may implement mobility management functions to track a current location of the UE 402 to facilitate paging, bearer activation/deactivation, handovers, gateway selection, authentication, etc.
[0060] The SGW 426 may terminate an SI interface toward the RAN and route data packets between the RAN and the LTE CN 422. The SGW 426 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. [0061] The SGSN 428 may track a location of the UE 402 and perform security functions and access control. In addition, the SGSN 428 may perform inter-EPC node signaling for mobility between different RAT networks; PDN and S-GW selection as specified by MME 424; MME selection for handovers; etc. The S3 reference point between the MME 424 and the SGSN 428 may enable user and bearer information exchange for inter-3GPP access network mobility in idle/active states.
[0062] The HSS 430 may include a database for network users, including subscription- related information to support the network entities' handling of communication sessions. The HSS 430 can provide support for routing/roaming, authentication, authorization, naming/addressing resolution, location dependencies, etc. An S6a reference point between the HSS 430 and the MME 424 may enable transfer of subscription and authentication data for authenticating/authorizing user access to the LTE CN 420.
[0063] The PGW 432 may terminate an SGi interface toward a data network (DN) 436 that may include an application/content server 438. The PGW 432 may route data packets between the LTE CN 422 and the data network 436. The PGW 432 may be coupled with the SGW 426 by an S5 reference point to facilitate user plane tunneling and tunnel management. The PGW 432 may further include a node for policy enforcement and charging data collection (for example, PCEF). Additionally, the SGi reference point between the PGW 432 and the data network YX 36 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 432 may be coupled with a PCRF 434 via a Gx reference point. [0064] The PCRF 434 is the policy and charging control element of the LTE CN 422. The PCRF 434 may be communicatively coupled to the app/content server 438 to determine appropriate QoS and charging parameters for service flows. The PCRF 432 may provision associated rules into a PCEF (via Gx reference point) with appropriate TFT and QCL
[0065] In some embodiments, the CN 420 may be a 5GC 440. The 5GC 440 may include an AUSF 442, AMF 444, SMF 446, UPF 448, NSSF 450, NEF 452, NRF 454, PCF 456, UDM 458, and AF 460 coupled with one another over interfaces (or "reference points") as shown. Functions of the elements of the 5GC 440 may be briefly introduced as follows. [0066] The AUSF 442 may store data for authentication of UE 402 and handle authentication-related functionality. The AUSF 442 may facilitate a common authentication framework for various access types. In addition to communicating with other elements of the 5GC 440 over reference points as shown, the AUSF 442 may exhibit an Nausf service-based interface. [0067] The AMF 444 may allow other functions of the 5GC 440 to communicate with the UE 402 and the RAN 404 and to subscribe to notifications about mobility events with respect to the UE 402. The AMF 444 may be responsible for registration management (for example, for registering UE 402), connection management, reachability management, mobility management, lawful interception of AMF-related events, and access authentication and authorization. The AMF 444 may provide transport for SM messages between the UE 402 and the SMF 446, and act as a transparent proxy for routing SM messages. AMF 444 may also provide transport for SMS messages between UE 402 and an SMSF. AMF 444 may interact with the AUSF 442 and the UE 402 to perform various security anchor and context management functions. Furthermore, AMF 444 may be a termination point of a RAN CP interface, which may include or be an N2 reference point between the RAN 404 and the AMF 444; and the AMF 444 may be a termination point of NAS (N 1) signaling, and perform NAS ciphering and integrity protection. AMF 444 may also support NAS signaling with the UE 402 over an N3 IWF interface.
[0068] The SMF 446 may be responsible for SM (for example, session establishment, tunnel management between UPF 448 and AN 408); UE IP address allocation and management (including optional authorization); selection and control of UP function; configuring traffic steering at UPF 448 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 444 over N2 to AN 408; 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 402 and the data network 436.
[0069] The UPF 448 may act as an anchor point for intra-RAT and inter-RAT mobility, an external PDU session point of interconnect to data network 436, and a branching point to support multi-homed PDU session. The UPF 448 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, uplink/downlink 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 448 may include an uplink classifier to support routing traffic flows to a data network.
[0070] The NSSF 450 may select a set of network slice instances serving the UE 402. The NSSF 450 may also determine allowed NSSAI and the mapping to the subscribed S-NSSAIs, if needed. The NSSF 450 may also determine the AMF set to be used to serve the UE 402, or a list of candidate AMFs based on a suitable configuration and possibly by querying the NRF 454. The selection of a set of network slice instances for the UE 402 may be triggered by the AMF 444 with which the UE 402 is registered by interacting with the NSSF 450, which may lead to a change of AMF. The NSSF 450 may interact with the AMF 444 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 450 may exhibit an Nnssf service-based interface.
[0071] The NEF 452 may securely expose services and capabilities provided by 3GPP network functions for third party, internal exposure/re-exposure, AFs (e.g., AF 460), edge computing or fog computing systems, etc. In such embodiments, the NEF 452 may authenticate, authorize, or throttle the AFs. NEF 452 may also translate information exchanged with the AF 460 and information exchanged with internal network functions. For example, the NEF 452 may translate between an AF-Service-ldentifier and an internal 5GC information. NEF 452 may also receive information from other NFs based on exposed capabilities of other NFs. This information may be stored at the NEF 452 as structured data, or at a data storage NF using standardized interfaces. The stored information can then be re-exposed by the NEF 452 to other NFs and AFs, or used for other purposes such as analytics. Additionally, the NEF 452 may exhibit an Nnef servicebased interface.
[0072] The NRF 454 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 454 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 454 may exhibit the Nnrf service-based interface.
[0073] The PCF 456 may provide policy rules to control plane functions to enforce them, and may also support unified policy framework to govern network behavior. The PCF 456 may also implement a front end to access subscription information relevant for policy decisions in a UDR of the UDM 458. In addition to communicating with functions over reference points as shown, the PCF 456 exhibit an Npcf service-based interface.
[0074] The UDM 458 may handle subscription-related information to support the network entities' handling of communication sessions, and may store subscription data of UE 402. For example, subscription data may be communicated via an N8 reference point between the UDM 458 and the AMF 444. The UDM 458 may include two parts, an application front end and a UDR. The UDR may store subscription data and policy data for the UDM 458 and the PCF 456, and/or structured data for exposure and application data (including PFDs for application detection, application request information for multiple UEs 402) for the NEF 452. The Nudr service-based interface may be exhibited by the UDR 421 to allow the UDM 458, PCF 456, and NEF 452 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 458 may exhibit the Nudm service-based interface.
[0075] The AF 460 may provide application influence on traffic routing, provide access to
NEF, and interact with the policy framework for policy control. [0076] In some embodiments, the 5GC 440 may enable edge computing by selecting operator/3rd party services to be geographically close to a point that the UE 402 is attached to the network. This may reduce latency and load on the network. To provide edge-computing implementations, the 5GC 440 may select a UPF 448 close to the UE 402 and execute traffic steering from the UPF 448 to data network 436 via the N6 interface. This may be based on the UE subscription data, UE location, and information provided by the AF 460. In this way, the AF 460 may influence UPF (re)selection and traffic routing. Based on operator deployment, when AF 460 is considered to be a trusted entity, the network operator may permit AF 460 to interact directly with relevant NFs. Additionally, the AF 460 may exhibit an Naf service-based interface.
[0077] The data network 436 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 438.
[0078] Fig. 5 schematically illustrates a wireless network 500 in accordance with various embodiments. The wireless network 500 may include a UE 502 in wireless communication with an AN 504. The UE 502 and AN 504 may be similar to, and substantially interchangeable with, like- named components described elsewhere herein.
[0079] The UE 502 may be communicatively coupled with the AN 504 via connection 506.

[0082] The modem platform 510 may further include digital baseband circuitry 516 that may implement one or more layer operations that are "below" layer operations performed by the protocol processing circuitry 514 in a network protocol stack. These operations may include, for example, PHY operations including one or more of HARQ-ACK functions, scrambling/descrambling, encoding/decoding, layer mapping/de-mapping, modulation symbol mapping, received symbol/bit metric determination, multi-antenna port precoding/decoding, which may include one or more of space-time, space-frequency or spatial coding, reference signal generation/detection, preamble sequence generation and/or decoding, synchronization sequence generation/detection, control channel signal blind decoding, and other related functions.
[0083] The modem platform 510 may further include transmit circuitry 518, receive circuitry 520, RF circuitry 522, and RF front end (RFFE) 524, which may include or connect to one or more antenna panels 526. Briefly, the transmit circuitry 518 may include a digital-to-analog converter, mixer, intermediate frequency (IF) components, etc.; the receive circuitry 520 may include an analog-to-digital converter, mixer, IF components, etc.; the RF circuitry 522 may include a low-noise amplifier, a power amplifier, power tracking components, etc.; RFFE 524 may include filters (for example, surface/bulk acoustic wave filters), switches, antenna tuners, beamforming components (for example, phase-array antenna components), etc. The selection and arrangement of the components of the transmit circuitry 518, receive circuitry 520, RF circuitry 522, RFFE 524, and antenna panels 526 (referred generically as "transmit/receive components") may be specific to details of a specific implementation such as, for example, whether communication is TDM or FDM, in mmWave or sub-6 gHz frequencies, etc. In some embodiments, the transmit/receive components may be arranged in multiple parallel transmit/receive chains, may be disposed in the same or different chips/modules, etc.
[0084] In some embodiments, the protocol processing circuitry 514 may include one or more instances of control circuitry (not shown) to provide control functions for the transmit/receive components. [0085] A UE reception may be established by and via the antenna panels 526, RFFE 524, RF circuitry 522, receive circuitry 520, digital baseband circuitry 516, and protocol processing circuitry 514. In some embodiments, the antenna panels 526 may receive a transmission from the AN 504 by receive-beamforming signals received by a plurality of antennas/antenna elements of the one or more antenna panels 526.
[0086] A UE transmission may be established by and via the protocol processing circuitry 514, digital baseband circuitry 516, transmit circuitry 518, RF circuitry 522, RFFE 524, and antenna panels 526. In some embodiments, the transmit components of the UE 504 may apply a spatial filter to the data to be transmitted to form a transmit beam emitted by the antenna elements of the antenna panels 526.
[0087] Similar to the UE 502, the AN 504 may include a host platform 528 coupled with a modem platform 530. The host platform 528 may include application processing circuitry 532 coupled with protocol processing circuitry 534 of the modem platform 530. The modem platform may further include digital baseband circuitry 536, transmit circuitry 538, receive circuitry 540, RF circuitry 542, RFFE circuitry 544, and antenna panels 546. The components of the AN 504 may be similar to and substantially interchangeable with like-named components of the UE 502. In addition to performing data transmission/reception as described above, the components of the AN 508 may perform various logical functions that include, for example, RNC functions such as radio bearer management, uplink and downlink dynamic radio resource management, and data packet scheduling.

Any characters between the start tag and end tag, if any, are the element's content (referred to herein as "content items" or the like).
[00235] The content of an entity may include one or more content items, each of which has an associated datatype representation. A content item may include, for example, attribute values, character values, URIs, qualified names (qnames), parameters, and the like. A qname is a fully qualified name of an element, attribute, or identifier in an information object. A qname associates a URI of a namespace with a local name of an element, attribute, or identifier in that namespace. To make this association, the qname assigns a prefix to the local name that corresponds to its namespace. The qname comprises a URI of the namespace, the prefix, and the local name. Namespaces are used to provide uniquely named elements and attributes in information objects. Content items may include text content (e.g., "<element>content item</element>"), attributes (e.g., "<element attribute="attributeValue">"), and other elements referred to as "child elements" (e.g., "<elementlxelement2>content item</element2x/elementl>").
