[0020] DETAILED DESCRIPTION
[0021] 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).
[0022] Time Division Duplex (TDD) may be used in commercial new radio (NR) deployments. As used herein, TDD may refer to a duplexing scheme wherein one or more time domain resource(s) is / are split between downlink (DL) and uplink (UL) symbols. Allocation of a limited time duration for the UL in TDD may result in reduced coverage and increased latency for a given target data rate. To improve the performance for UL transmission in TDD system, simultaneous transmission and reception of DL symbols and UL symbols, respectively, may be considered. This simultaneous transmission / reception may also be referred to herein as “full duplex communication.’’ In this regard, subband non-overlapping full duplex (SBFD) operation may be considered.
[0023] For SBFD, within a carrier bandwidth, some bandwidth can be allocated as UL, while some bandwidth can be allocated as DL within the same symbol. However, when the UL and DL is allocated within the same symbol (i.e., within the same time domain), the UL and DL resources are non-overlapping in frequency domain. Under this operational mode, at a given symbol a base station such as a gNodeB (gNB) may simultaneously transmit DL signals and receive UL signals. In some embodiments, however, the UE may only be configured to transmit or receive in a given symbol, and may not be configured to perform both functions simultaneously.
[0024] Figure 1 illustrates one example of subband non-overlapping full duplex (SBFD) for a NR system. In the figure, in the SBFD symbols, part of the carrier bandwidth may be allocated for DL while another part of the carrier bandwidth may be allocated for UL.
[0025] In order to improve the uplink coverage, repetitions of UL transmission including physical uplink control channel (PUCCH) and physical random access channel (PRACH) may be employed. For SBFD operation, separate configuration of uplink transmissions on SBFD symbols and non-SBFD symbols may be configured in some embodiments. In this case, it may be desirable to enable the repetitions of uplink transmission including PUCCH and PRACH in case of SBFD operations. Embodiments herein may relate to PRACH and / or PUCCH repetitions for subband non-overlapping full duplex (SBFD) operation.
[0026] PUCCH repetitions for SBFD operation
[0027] Example embodiments related to PUCCH repetitions for SBFD operation may include one or more of the following:
[0028] In one embodiment, separate PUCCH resource configuration may be configured for a UE for PUCCH transmission in SBFD symbols and non-SBFD symbols.
[0029] In one option, if a UE does not have dedicated PUCCH resource configuration, a UE can be provided with separate PUCCH resource sets which are indicated by separate pucch- ResourceCommon radio resource control (RRC) information element. In this case, a first pucch- ResourceCommon is configured for a first PUCCH resource set for non-SBFD symbols while a second pucch-ResourceCommon is configured for a second PUCCH resource set for SBFD symbols.
[0030] Further, if the second pucch-ResourceCommon is not configured, same PUCCH resource set indicated by the first pucch-ResourceCommon is used for both SBFD and non-SBFD symbols.
[0031] In some aspects, a physical resource block (PRB) location of the PUCCH transmission in non-SBFD symbols and SBFD symbols can be determined in accordance with the active UL bandwidth part (BWP) that is associated with non-SBFD symbols and in accordance with the UL subband (SB) that is associated with SBFD symbols, respectively.
[0032] In another embodiment, for PUCCH with repetitions, the PUCCH repetitions are transmitted on the PUCCH resources which are configured for both non-SBFD and SBFD symbols. For this option, the PUCCH resource configuration for the PUCCH repetitions is determined in accordance with the PUCCH resource configuration from the first PUCCH repetition.
[0033] In some aspects, the number of repetitions for the PUCCH transmission is determined in accordance with the PUCCH resource in the first PUCCH repetition.
[0034] In one option, for PUCCH carrying hybrid automatic repeat request (HARQ)- acknowledgement (ACK) feedback in response to Msg4 transmission, if only one value is configured for the PUCCH repetition via numberOfPUCCHforMsg4HARQACK-RepetitionsList, the number of repetitions for the PUCCH transmission on both non-SBFD and SBFD symbols is determined in accordance with the one value.
[0035] In another option, for PUCCH carrying HARQ-ACK feedback in response to Msg4 transmission, if more than one values are configured for the PUCCH repetitions via mimberOfPUCCHforMsg4HARQACK-RepetitionsList, the number of repetition for the PUCCH transmission on both non-SBFD and SBFD symbols is determined based on the value that is indicated by Downlink assignment index field in the DCI format l_0 with CRC scrambled by a temporary cell (TC) radio network temporary identifier (RNTI).
[0036] In one option, for PUCCH carrying HARQ-ACK feedback in response to Msg4 transmission, a UE can be provided with separate list of possible values for number of the PUCCH repetitions by separate numberOfPUCCHforMsg4HARQACK-RepetitionsList wherein a first numberOfRUCCHforMsg4HARQACK-RepetitionsList is configured for non-SBFD symbols while a second mimberOJPUCCHforMsg4HARQACK-RepetitionsList is configured for SBFD symbols.
[0037] In some aspects, UE applies the number of PUCCH repetitions corresponding to the first numberOfPUCCHforMsg4HARQACK-RepetitionsList if the first symbol of the PUCCH transmission is non-SBFD symbol, while UE applies the number of PUCCH repetitions corresponding to the second numberOfPUCCHforMsg4HARQACK-RepetitionsList if the first symbol of the PUCCH transmission is SBFD symbol.
[0038] In another option, a single value of number of repetitions of PUCCH may be provided that indicates the total number of repetitions of PUCCH spanning PUCCH transmissions in non-SBFD and SBFD symbols.
[0039] In some aspects, the above options can also apply for the PUCCH other than the PUCCH carrying HARQ-ACK feedback in response to Msg4 transmission, if a UE does not have dedicated PUCCH resource configuration.
[0040] In addition, the PUCCH resource index that is determined for the first PUCCH repetition is applied for the subsequent PUCCH repetitions in non-SBFD and / or SBFD symbols.
[0041] Further, in case of single-transmit / receive point (TRP) operation, the spatial relation or beam of PUCCH transmission for the subsequent PUCCH repetitions after the first PUCCH repetition is determined based on the spatial relation or beam of the first PUCCH transmissions. In one example, same spatial relation or beam as determined for the first PUCCH repetition is applied for that of the subsequent PUCCH repetitions.
[0042] Figure 2 illustrates one example of PUCCH repetitions in SBFD and non-SBFD symbols when a UE does not have dedicated PUCCH resource configuration. In the figure, two PUCCH repetitions are configured, and are transmitted in both non-SBFD and SBFD symbols. Further, the PUCCH resource index that is determined in the first slot is applied for the PUCCH repetition in the second slot. The PRB location of the PUCCH repetition in non-SBFD symbols and SBFD symbols is determined in accordance with the active UL bandwidth part (B WP) or the UL subband (SB) that is associated with non-SBFD symbols and SBFD symbols, respectively.
[0043] In another embodiment, for PUCCH with repetitions, the PUCCH repetitions are transmitted on the PUCCH resources which are configured for either non-SBFD or SBFD symbols. In this case, if the first PUCCH repetition is determined to be transmitted on the non- SBFD symbols, the subsequent PUCCH repetitions are also transmitted on the non-SBFD symbols. If the first PUCCH repetition is determined to be transmitted on the SBFD symbols, the subsequent PUCCH repetitions are also transmitted on the SBFD symbols.
[0044] Figure 3 illustrates one example of PUCCH repetitions in only non-SBFD symbols. In the example, 2 PUCCH repetitions are configured. Further, the first PUCCH repetition is determined to be transmitted on the non-SBFD symbol in the first slot. In this case, the second PUCCH repetition is also transmitted in the non-SBFD symbol in the third slot.
[0045] In another embodiment, when PUCCH is a sub-slot PUCCH, e.g., when subslotLengthForPUCCH is provided in PUCCH-Config, and sub-slot repetitions are enabled or disabled, the PUCCH resource determination for initial transmission and repetitions may apply the embodiments provided above for PUCCH transmissions / repetitions in both SBFD and non- SBFD symbols, or in either SBFD or non-SBFD symbols, with number of symbols in a slot for PUCCH equal to a sub-slot length provided by subslotLengthForPUCCH.
[0046] PRACH repetitions for SBFD operation
[0047] Example embodiments of PRACH repetitions for SBFD operation are provided as follows: In one embodiment, separate PRACH configurations may be configured for a UE in SBFD symbols and non-SBFD symbols.
[0048] In some aspects, UE may be provided with separate RACH-ConfigGeneric for SBFD symbols and non-SBFD symbols, respectively. In this case, a first RACH-ConfigGeneric may be configured for non-SBFD symbols, while a second RACH-ConfigGeneric may be configured for SBFD symbols.
[0049] In some aspects, the second PRACH configuration may be provided to a UE for PRACH transmissions in SBFD symbols or in both SBFD and non-SBFD symbols when in RRC_CONNECTED mode. Alternatively, the second PRACH configuration may be provided to a UE for PRACH transmission in SBFD or across both SBFD and non-SBFD symbols in each of RRC_CONNECTED and RRC_IDLE and RRC_INACTIVE states. Further, for the latter option, the second PRACH configuration may be provided to the UE as part of the RRCRelease message.
[0050] Further, if the second RACH-ConfigGeneric is not configured, same PRACH configuration indicated by the first RACH-ConfigGeneric is used for both SBFD and non-SBFD symbols. In this case, PRACH occasions that are within the UL subband and SBFD symbols can be considered as valid PRACH occasions and can be used for PRACH transmission. In addition, PRACH occasions that collide with DL subband in SBFD symbols can be considered as invalid PRACH occasions and cannot be used for PRACH transmissions.
[0051] For this option, UE may continue to use the configurations for random access which are based on the initial PRACH transmission on either SBFD or non-SBFD symbols. In particular, when a UE transmits the PRACH preamble using the PRACH configuration in non-SBFD symbols, UE continues to use the configurations during random access based on the PRACH configurations on non-SBFD symbols or vice versa.
[0052] In one example, when a UE transmits the PRACH preamble using the PRACH configuration in SBFD symbols, a UE attempts to detect a DCI format l_0 with CRC scrambled by a corresponding RA-RNTI during a window which is configured by ra-ResponseWindow in accordance with the PRACH configurations in SBFD symbols.
[0053] In another example, when a UE transmits the PRACH preamble using the PRACH configuration in SBFD symbols, UE may apply the power ramping step size in accordance with the PRACH configuration on SBFD symbols that may be different from that configured for PRACH transmissions in non-SBFD symbols.
[0054] Further, UE may only switch to the PRACH configurations for PRACH retransmission if the number of PRACH retransmission reaches to a maximum value, which may be configured by higher layers. In this case, if K PRACH retransmissions in accordance with the PRACH configuration on SBFD symbols are not successful, UE may switch to PRACH configuration on non-SBFD symbols for PRACH transmissions.
[0055] In another embodiment, for PRACH with repetitions, the PRACH repetitions may be transmitted on the valid PRACH occasions (which may also be referred to as “RACH occasions” or “ROs”) that are configured for both SBFD and non-SBFD symbols.
[0056] In one option, if each RO is associated with one synchronization signal block (SSB) for PRACH configuration in both SBFD and non-SBFD symbols, all ROs in both SBFD and non- SBFD symbols that are associated with the same synchronization signal block (SSB) index and have same starting resource block (RB) as the starting RO can form a RO group. As an example of this case, an RO may correspond to symbols - some of which are SBFD symbols and others are non-SBFD symbols. Further, for this example, the RO is mapped to the same PRBs in the frequency dimension in both SBFD and non-SBFD symbols.
[0057] In another option, if each RO is associated with multiple SSB for PRACH configuration in both SBFD and non-SBFD symbols, all ROs in both SBFD and non-SBFD symbols that are associated with the same SSB indexes and each same SSB index of the SSB indexes is associated with the same preambles, and have same starting RB as the starting RO can form a RO group.
[0058] Further, the first valid PRACH occasion of the first set is the first valid PRACH occasion and the first valid PRACH occasion of subsequent sets, if any, is determined according to an ordering of valid PRACH occasions in both SBFD and non-SBFD symbols
[0059] • first, in increasing order of frequency resource indexes for frequency multiplexed PRACH occasions in both SBFD and non-SBFD symbols
[0060] • second, in increasing order of time resource indexes for time multiplexed PRACH occasions in both SBFD and non-SBFD symbols
[0061] In some aspects, for PRACH repetitions in both SBFD and non-SBFD symbols, a time period, starting from frame 0, is the smallest integer number of association pattern periods such that at least one set of valid PRACH occasions for both SBFD and non-SBFD symbols for each of the / VyfBSS / PBCH block indexes can be determined within the time period for all configured number of preamble repetitions. The set(s) of valid PRACH occasions for both SBFD and non- SBFD symbols for each configured number of preamble repetitions repeats every time period.
[0062] As a further extension, to enable PRACH repetitions in both SBFD and non-SBFD symbols, UE may expect a same PRACH configuration for one or more parameters, which may include a number of frequency division multiplexed (FDM’ed) PRACH occasions and / or a SSB to RO mapping ratio.
[0063] Figure 4 illustrates one example of PRACH repetitions in both non-SBFD and SBFD symbols. In the figure, 2 PRACH repetitions are configured and determined. 2 SSBs are configured and 1 SSB is associated with 1 PRACH occasion. In this case, UE may transmit two PRACH repetitions on RO#0 on non-SBFD symbols and RO#0 in SBFD symbols which are associated with SSB#0.
[0064] In another option, if each RO is associated with one SSB for PRACH configuration in both SBFD and non-SBFD symbols, all ROs in both SBFD and non-SBFD symbols that are associated with the same SSB index and have same frequency resource index as the starting RO can form a RO group.
[0065] In yet another option, if each RO is associated with multiple SSB for PRACH configuration in both SBFD and non-SBFD symbols, all ROs in both SBFD and non-SBFD symbols that are associated with the same SSB indexes and each same SSB index of the SSB indexes is associated with the same preambles, and have same frequency resource index as the starting RO can form a RO group.
[0066] Further, the first valid PRACH occasion of the first set is the first valid PRACH occasion and the first valid PRACH occasion of subsequent sets, if any, is determined according to an ordering of valid PRACH occasions in both SBFD and non-SBFD symbols
[0067] • first, in increasing order of frequency resource indexes for frequency multiplexed PRACH occasions in both SBFD and non-SBFD symbols
[0068] • second, in increasing order of time resource indexes for time multiplexed PRACH occasions in both SBFD and non-SBFD symbols
[0069] In another embodiment, for PRACH with repetitions, the PRACH repetitions are transmitted on the valid PRACH occasions which are configured for either non-SBFD or SBFD symbols. In this case, if the first PRACH repetition is transmitted on the non-SBFD symbols, the subsequent PRACH repetitions are also transmitted on the non-SBFD symbols. If the first PRACH repetition is transmitted on the SBFD symbols, the subsequent PRACH repetitions are also transmitted on the SBFD symbols.
[0070] In this case, the existing SSB to RO group association rule and the mapping of PRACH repetition on valid RO group can be applied for PRACH repetitions on SBFD symbols and non- SBFD symbols, respectively.
[0071] In some aspects, for PRACH repetitions in either non-SBFD or SBFD symbols, a time period, starting from frame 0, is the smallest integer number of association pattern periods such that at least one set of valid PRACH occasions for either non-SBFD or SBFD symbols for each of theSBSS / PBCH block indexes can be determined within the time period for all configured number of preamble repetitions, respectively. The set(s) of valid PRACH occasions for either SBFD or non-SBFD symbols for each configured number of preamble repetitions repeats every time period, respectively.
[0072] Figure 5 illustrates one example of PRACH repetitions in only non-SBFD symbols. In the figure, 2 PRACH repetitions are configured and determined. 2 SSBs are configured and 1 SSB is associated with 1 PRACH occasion. In this case, UE may transmit two PRACH repetitions on RO#0 and RO#2 on non-SBFD symbols which are associated with SSB#0.
[0073] SYSTEMS AND IMPLEMENTATIONS
[0074] Figures 6-9 illustrate various systems, devices, and components that may implement aspects of disclosed embodiments.
[0075] Figure 6 illustrates a network 600 in accordance with various embodiments. The network 600 may operate in a manner consistent with 3GPP technical specifications for LTE or 5G / NR systems. However, the example embodiments are not limited in this regard and the described embodiments may apply to other networks that benefit from the principles described herein, such as future 3 GPP systems, or the like.
[0076] The network 600 may include a UE 602, which may include any mobile or non-mobile computing device designed to communicate with a RAN 604 via an over-the-air connection. The UE 602 may be communicatively coupled with the RAN 604 by a Uu interface. The UE 602 may be, but is not limited to, a smartphone, tablet computer, wearable computer device, desktop computer, laptop computer, in-vehicle infotainment, in-car entertainment device, instrument cluster, head-up display device, onboard diagnostic device, dashtop mobile equipment, mobile data terminal, electronic engine management system, electronic / engine control unit, electronic / engine control module, embedded system, sensor, microcontroller, control module, engine management system, networked appliance, machine-type communication device, M2M or D2D device, loT device, etc.
[0077] In some embodiments, the network 600 may include a plurality of UEs coupled directly with one another via a sidelink interface. The UEs may be M2M / D2D devices that communicate using physical sidelink channels such as, but not limited to, PSBCH, PSDCH, PSSCH, PSCCH, PSFCH, etc.
[0078] In some embodiments, the UE 602 may additionally communicate with an AP 606 via an over-the-air connection. The AP 606 may manage a WLAN connection, which may serve to offload some / all network traffic from the RAN 604. The connection between the UE 602 and the AP 606 may be consistent with any IEEE 802.11 protocol, wherein the AP 606 could be a wireless fidelity (Wi-Fi®) router. In some embodiments, the UE 602, RAN 604, and AP 606 may utilize cellular- WLAN aggregation (for example, LWA / LWIP). Cellular- WLAN aggregation may involve the UE 602 being configured by the RAN 604 to utilize both cellular radio resources and WLAN resources.
[0079] The RAN 604 may include one or more access nodes, for example, AN 608. AN 608 may terminate air-interface protocols for the UE 602 by providing access stratum protocols including RRC, PDCP, RLC, MAC, and LI protocols. In this manner, the AN 608 may enable data / voice connectivity between CN 620 and the UE 602. In some embodiments, the AN 608 may be implemented in a discrete device or as one or more software entities running on server computers as part of, for example, a virtual network, which may be referred to as a CRAN or virtual baseband unit pool. The AN 608 be referred to as a BS, gNB, RAN node, eNB, ng-eNB, NodeB, RSU, TRxP, TRP, etc. The AN 608 may be a macrocell base station or a low power base station for providing femtocells, picocells or other like cells having smaller coverage areas, smaller user capacity, or higher bandwidth compared to macrocells.
[0080] In embodiments in which the RAN 604 includes a plurality of ANs, they may be coupled with one another via an X2 interface (if the RAN 604 is an LTE RAN) or an Xn interface (if the RAN 604 is a 5G RAN). The X2 / Xn interfaces, which may be separated into control / user plane interfaces in some embodiments, may allow the ANs to communicate information related to handovers, data / context transfers, mobility, load management, interference coordination, etc.
[0081] The ANs of the RAN 604 may each manage one or more cells, cell groups, component carriers, etc. to provide the UE 602 with an air interface for network access. The UE 602 may be simultaneously connected with a plurality of cells provided by the same or different ANs of the RAN 604. For example, the UE 602 and RAN 604 may use carrier aggregation to allow the UE 602 to connect with a plurality of component carriers, each corresponding to a Pcell or Scell. In dual connectivity scenarios, a first AN may be a master node that provides an MCG and a second AN may be secondary node that provides an SCG. The first / second ANs may be any combination of eNB, gNB, ng-eNB, etc.
[0082] The RAN 604 may provide the air interface over a licensed spectrum or an unlicensed spectrum. To operate in the unlicensed spectrum, the nodes may use LAA, eLAA, and / or feLAA mechanisms based on CA technology with PCells / Scells. Prior to accessing the unlicensed spectrum, the nodes may perform medium / carrier-sensing operations based on, for example, a listen-before-talk (LBT) protocol.
[0083] In V2X scenarios the UE 602 or AN 608 may be or act as a RSU, which may refer to any transportation infrastructure entity used for V2X communications. An RSU may be implemented in or by a suitable AN or a stationary (or relatively stationary) UE. An RSU implemented in or by: a UE may be referred to as a “UE-type RSU”; an eNB may be referred to as an “eNB-type RSU”; a gNB may be referred to as a “gNB-type RSU”; and the like. In one example, an RSU is a computing device coupled with radio frequency circuitry located on a roadside that provides connectivity support to passing vehicle UEs. The RSU may also include internal data storage circuitry to store intersection map geometry, traffic statistics, media, as well as applications / software to sense and control ongoing vehicular and pedestrian traffic. The RSU may provide very low latency communications required for high speed events, such as crash avoidance, traffic warnings, and the like. Additionally or alternatively, the RSU may provide other cellular / WLAN communications services. The components of the RSU may be packaged in a weatherproof enclosure suitable for outdoor installation, and may include a network interface controller to provide a wired connection (e.g., Ethernet) to a traffic signal controller or a backhaul network.
[0084] In some embodiments, the RAN 604 may be an LTE RAN 610 with eNBs, for example, eNB 612. The LTE RAN 610 may provide an LTE air interface with the following characteristics: SCS of 15 kHz; CP-OFDM waveform for DL and SC-FDMA waveform for UL; turbo codes for data and TBCC for control; etc. The LTE air interface may rely on CSI-RS for CSI acquisition and beam management; PDSCH / PDCCH DMRS for PDSCH / PDCCH demodulation; and CRS for cell search and initial acquisition, channel quality measurements, and channel estimation for coherent demodulation / detection at the UE. The LTE air interface may operating on sub-6 GHz bands.
[0085] In some embodiments, the RAN 604 may be an NG-RAN 614 with gNBs, for example, gNB 616, or ng-eNBs, for example, ng-eNB 618. The gNB 616 may connect with 5G-enabled UEs using a 5G NR interface. The gNB 616 may connect with a 5G core through an NG interface, which may include an N2 interface or an N3 interface. The ng-eNB 618 may also connect with the 5G core through an NG interface, but may connect with a UE via an LTE air interface. The gNB 616 and the ng-eNB 618 may connect with each other over an Xn interface.
[0086] In some embodiments, the NG interface may be split into two parts, an NG user plane (NG-U) interface, which carries traffic data between the nodes of the NG-RAN 614 and a UPF 648 (e.g., N3 interface), and an NG control plane (NG-C) interface, which is a signaling interface between the nodes of the NG-RAN614 and an AMF 644 (e.g., N2 interface).
[0087] The NG-RAN 614 may provide a 5G-NR air interface with the following characteristics: variable SCS; CP-OFDM for DL, CP-OFDM and DFT-s-OFDM for UL; polar, repetition, simplex, and Reed-Muller codes for control and LDPC for data. The 5G-NR air interface may rely on CSLRS, 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.
[0088] In some embodiments, the 5G-NR air interface may utilize BWPs for various purposes. For example, BWP can be used for dynamic adaptation of the SCS. For example, the UE 602 can be configured with multiple BWPs where each BWP configuration has a different SCS. When a BWP change is indicated to the UE 602, the SCS of the transmission is changed as well. Another use case example of BWP is related to power saving. In particular, multiple BWPs can be configured for the UE 602 with different 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 602 and in some cases at the gNB 616. A BWP containing a larger number of PRBs can be used for scenarios with higher traffic load.
[0089] The RAN 604 is communicatively coupled to CN 620 that includes network elements to provide various functions to support data and telecommunications services to customers / subscribers (for example, users of UE 602). The components of the CN 620 may be implemented in one physical node or separate physical nodes. In some embodiments, NFV may be utilized to virtualize any or all of the functions provided by the network elements of the CN 620 onto physical compute / storage resources in servers, switches, etc. A logical instantiation of the CN 620 may be referred to as a network slice, and a logical instantiation of a portion of the CN 620 may be referred to as a network sub-slice.
[0090] In some embodiments, the CN 620 may be an LTE CN 622, which may also be referred to as an EPC. The LTE CN 622 may include MME 624, SGW 626, SGSN 628, HSS 630, PGW 632, and PCRF 634 coupled with one another over interfaces (or “reference points”) as shown. Functions of the elements of the LTE CN 622 may be briefly introduced as follows.
[0091] The MME 624 may implement mobility management functions to track a current location of the UE 602 to facilitate paging, bearer activation / deactivation, handovers, gateway selection, authentication, etc.
[0092] The SGW 626 may terminate an S 1 interface toward the RAN and route data packets between the RAN and the LTE CN 622. The SGW 626 may be a local mobility anchor point for inter-RAN node handovers and also may provide an anchor for inter-3GPP mobility. Other responsibilities may include lawful intercept, charging, and some policy enforcement.
[0093] The SGSN 628 may track a location of the UE 602 and perform security functions and access control. In addition, the SGSN 628 may perform inter-EPC node signaling for mobility between different RAT networks; PDN and S-GW selection as specified by MME 624; MME selection for handovers; etc. The S3 reference point between the MME 624 and the SGSN 628 may enable user and bearer information exchange for inter-3GPP access network mobility in idle / active states.
[0094] The HSS 630 may include a database for network users, including subscription-related information to support the network entities’ handling of communication sessions. The HSS 630 can provide support for routing / roaming, authentication, authorization, naming / addressing resolution, location dependencies, etc. An S6a reference point between the HSS 630 and the MME 624 may enable transfer of subscription and authentication data for authenticating / authorizing user access to the LTE CN 620.
[0095] The PGW 632 may terminate an SGi interface toward a data network (DN) 636 that may include an application / content server 638. The PGW 632 may route data packets between the LTE CN 622 and the data network 636. The PGW 632 may be coupled with the SGW 626 by an S5 reference point to facilitate user plane tunneling and tunnel management. The PGW 632 may further include a node for policy enforcement and charging data collection (for example, PCEF). Additionally, the SGi reference point between the PGW 632 and the data network 6 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 632 may be coupled with a PCRF 634 via a Gx reference point.
[0096] The PCRF 634 is the policy and charging control element of the LTE CN 622. The PCRF 634 may be communicatively coupled to the app / content server 638 to determine appropriate QoS and charging parameters for service flows. The PCRF 632 may provision associated rules into a PCEF (via Gx reference point) with appropriate TFT and QCI.
[0097] In some embodiments, the CN 620 may be a 5GC 640. The 5GC 640 may include an AUSF 642, AMF 644, SMF 646, UPF 648, NSSF 650, NEF 652, NRF 654, PCF 656, UDM 658, and AF 660 coupled with one another over interfaces (or “reference points”) as shown. Functions of the elements of the 5GC 640 may be briefly introduced as follows.
[0098] The AUSF 642 may store data for authentication of UE 602 and handle authentication- related functionality. The AUSF 642 may facilitate a common authentication framework for various access types. In addition to communicating with other elements of the 5GC 640 over reference points as shown, the AUSF 642 may exhibit an Nausf service-based interface.
[0099] The AMF 644 may allow other functions of the 5GC 640 to communicate with the UE 602 and the RAN 604 and to subscribe to notifications about mobility events with respect to the UE 602. The AMF 644 may be responsible for registration management (for example, for registering UE 602), connection management, reachability management, mobility management, lawful interception of AMF-related events, and access authentication and authorization. The AMF 644 may provide transport for SM messages between the UE 602 and the SMF 646, and act as a transparent proxy for routing SM messages. AMF 644 may also provide transport for SMS messages between UE 602 and an SMSF. AMF 644 may interact with the AUSF 642 and the UE 602 to perform various security anchor and context management functions. Furthermore, AMF 644 may be a termination point of a RAN CP interface, which may include or be an N2 reference point between the RAN 604 and the AMF 644; and the AMF 644 may be a termination point of NAS (Nl) signaling, and perform NAS ciphering and integrity protection. AMF 644 may also support NAS signaling with the UE 602 over an N3 IWF interface.
[0100] The SMF 646 may be responsible for SM (for example, session establishment, tunnel management between UPF 648 and AN 608); UE IP address allocation and management (including optional authorization); selection and control of UP function; configuring traffic steering at UPF 648 to route traffic to proper destination; termination of interfaces toward policy control functions; controlling part of policy enforcement, charging, and QoS; lawful intercept (for SM events and interface to LI system); termination of SM parts of NAS messages; downlink data notification; initiating AN specific SM information, sent via AMF 644 over N2 to AN 608; and determining SSC mode of a session. SM may refer to management of a PDU session, and a PDU session or “session” may refer to a PDU connectivity service that provides or enables the exchange of PDUs between the UE 602 and the data network 636.
[0101] The UPF 648 may act as an anchor point for intra-RAT and inter-RAT mobility, an external PDU session point of interconnect to data network 636, and a branching point to support multi-homed PDU session. The UPF 648 may also perform packet routing and forwarding, perform packet inspection, enforce the user plane part of policy rules, lawfully intercept packets (UP collection), perform traffic usage reporting, perform QoS handling for a user plane (e.g., packet filtering, gating, UL / DL rate enforcement), perform uplink traffic verification (e.g., SDF- to-QoS flow mapping), transport level packet marking in the uplink and downlink, and perform downlink packet buffering and downlink data notification triggering. UPF 648 may include an uplink classifier to support routing traffic flows to a data network.
[0102] The NSSF 650 may select a set of network slice instances serving the UE 602. The NSSF 650 may also determine allowed NSSAI and the mapping to the subscribed S-NSSAIs, if needed. The NSSF 650 may also determine the AMF set to be used to serve the UE 602, or a list of candidate AMFs based on a suitable configuration and possibly by querying the NRF 654. The selection of a set of network slice instances for the UE 602 may be triggered by the AMF 644 with which the UE 602 is registered by interacting with the NSSF 650, which may lead to a change of AMF. The NSSF 650 may interact with the AMF 644 via an N22 reference point; and may communicate with another NSSF in a visited network via an N31 reference point (not shown). Additionally, the NSSF 650 may exhibit an Nnssf service-based interface.
[0103] The NEF 652 may securely expose services and capabilities provided by 3GPP network functions for third party, internal exposure / re-exposure, AFs (e.g., AF 660), edge computing or fog computing systems, etc. In such embodiments, the NEF 652 may authenticate, authorize, or throttle the AFs. NEF 652 may also translate information exchanged with the AF 660 and information exchanged with internal network functions. For example, the NEF 652 may translate between an AF-Service-Identifier and an internal 5GC information. NEF 652 may also receive information from other NFs based on exposed capabilities of other NFs. This information may be stored at the NEF 652 as structured data, or at a data storage NF using standardized interfaces. The stored information can then be re-exposed by the NEF 652 to other NFs and AFs, or used for other purposes such as analytics. Additionally, the NEF 652 may exhibit an Nnef service-based interface.
[0104] The NRF 654 may support service discovery functions, receive NF discovery requests from NF instances, and provide the information of the discovered NF instances to the NF instances. NRF 654 also maintains information of available NF instances and their supported services. As used herein, the terms “instantiate,” “instantiation,” and the like may refer to the creation of an instance, and an “instance” may refer to a concrete occurrence of an object, which may occur, for example, during execution of program code. Additionally, the NRF 654 may exhibit the Nnrf service-based interface.
[0105] The PCF 656 may provide policy rules to control plane functions to enforce them, and may also support unified policy framework to govern network behavior. The PCF 656 may also implement a front end to access subscription information relevant for policy decisions in a UDR of the UDM 658. In addition to communicating with functions over reference points as shown, the PCF 656 exhibit an Npcf service-based interface.
[0106] The UDM 658 may handle subscription-related information to support the network entities’ handling of communication sessions, and may store subscription data of UE 602. For example, subscription data may be communicated via an N8 reference point between the UDM 658 and the AMF 644. The UDM 658 may include two parts, an application front end and a UDR. The UDR may store subscription data and policy data for the UDM 658 and the PCF 656, and / or structured data for exposure and application data (including PFDs for application detection, application request information for multiple UEs 602) for the NEF 652. The Nudr service-based interface may be exhibited by the UDR 221 to allow the UDM 658, PCF 656, and NEF 652 to access a particular set of the stored data, as well as to read, update (e.g., add, modify), delete, and subscribe to notification of relevant data changes in the UDR. The UDM may include a UDM- FE, which is in charge of processing credentials, location management, subscription management and so on. Several different front ends may serve the same user in different transactions. The UDM-FE accesses subscription information stored in the UDR and performs authentication credential processing, user identification handling, access authorization, registration / mobility management, and subscription management. In addition to communicating with other NFs over reference points as shown, the UDM 658 may exhibit the Nudm service-based interface.
[0107] The AF 660 may provide application influence on traffic routing, provide access to NEF, and interact with the policy framework for policy control.
[0108] In some embodiments, the 5GC 640 may enable edge computing by selecting operator / 3rdparty services to be geographically close to a point that the UE 602 is attached to the network. This may reduce latency and load on the network. To provide edge-computing implementations, the 5GC 640 may select a UPF 648 close to the UE 602 and execute traffic steering from the UPF 648 to data network 636 via the N6 interface. This may be based on the UE subscription data, UE location, and information provided by the AF 660. In this way, the AF 660 may influence UPF (re)selection and traffic routing. Based on operator deployment, when AF 660 is considered to be a trusted entity, the network operator may permit AF 660 to interact directly with relevant NFs. Additionally, the AF 660 may exhibit an Naf service-based interface.
[0109] The data network 636 may represent various network operator services, Internet access, or third party services that may be provided by one or more servers including, for example, application / content server 638.

[0118] A UE transmission may be established by and via the protocol processing circuitry 714, digital baseband circuitry 716, transmit circuitry 718, RF circuitry 722, RFFE 724, and antenna panels 726. In some embodiments, the transmit components of the UE 704 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 726.
[0119] Similar to the UE 702, the AN 704 may include a host platform 728 coupled with a modem platform 730.

[0125] Figure 9 illustrates a network 900 in accordance with various embodiments. The network 900 may operate in a matter consistent with 3GPP technical specifications or technical reports for 6G systems. In some embodiments, the network 900 may operate concurrently with network 600. For example, in some embodiments, the network 900 may share one or more frequency or bandwidth resources with network 600. As one specific example, a UE (e.g., UE 902) may be configured to operate in both network 900 and network 600. Such configuration may be based on a UE including circuitry configured for communication with frequency and bandwidth resources of both networks 600 and 900. In general, several elements of network 900 may share one or more characteristics with elements of network 600. For the sake of brevity and clarity, such elements may not be repeated in the description of network 900.
[0126] The network 900 may include a UE 902, which may include any mobile or non-mobile computing device designed to communicate with a RAN 908 via an over-the-air connection. The UE 902 may be similar to, for example, UE 602.

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. Similarly, although not specifically shown in Figure 9, the UE 902 may be communicatively coupled with an AP such as AP 606 as described with respect to Figure 6. Additionally, although not specifically shown in Figure 9, in some embodiments the RAN 908 may include one or more ANss such as AN 608 as described with respect to Figure 6. The RAN 908 and / or the AN of the RAN 908 may be referred to as a base station (BS), a RAN node, or using some other term or name.
[0128] The UE 902 and the RAN 908 may be configured to communicate via an air interface that may be referred to as a sixth generation (6G) air interface. The 6G air interface may include one or more features such as communication in a terahertz (THz) or sub-THz bandwidth, or joint communication and sensing. As used herein, the term “joint communication and sensing” may refer to a system that allows for wireless communication as well as radar-based sensing via various types of multiplexing. As used herein, THz or sub-THz bandwidths may refer to communication in the 80 GHz and above frequency ranges. Such frequency ranges may additionally or alternatively be referred to as “millimeter wave” or “mmWave” frequency ranges.
[0129] The RAN 908 may allow for communication between the UE 902 and a 6G core network (CN) 910. Specifically, the RAN 908 may facilitate the transmission and reception of data between the UE 902 and the 6G CN 910. The 6G CN 910 may include various functions such as NSSF 650, NEF 652, NRF 654, PCF 656, UDM 658, AF 660, SMF 646, and AUSF 642. The 6G CN 910 may additional include UPF 648 and DN 636 as shown in Figure 9.
[0130] Additionally, the RAN 908 may include various additional functions that are in addition to, or alternative to, functions of a legacy cellular network such as a 4G or 5G network. Two such functions may include a Compute Control Function (Comp CF) 924 and a Compute Service Function (Comp SF) 936. The Comp CF 924 and the Comp SF 936 may be parts or functions of the Computing Service Plane. Comp CF 924 may be a control plane function that provides functionalities such as management of the Comp SF 936, computing task context generation and management (e.g., create, read, modify, delete), interaction with the underlying computing infrastructure for computing resource management, etc.. Comp SF 936 may be a user plane function that serves as the gateway to interface computing service users (such as UE 902) and computing nodes behind a Comp SF instance. Some functionalities of the Comp SF 936 may include: parse computing service data received from users to compute tasks executable by computing nodes; hold service mesh ingress gateway or service API gateway; service and charging policies enforcement; performance monitoring and telemetry collection, etc. In some embodiments, a Comp SF 936 instance may serve as the user plane gateway for a cluster of computing nodes. A Comp CF 924 instance may control one or more Comp SF 936 instances.
[0131] Two other such functions may include a Communication Control Function (Comm CF) 928 and a Communication Service Function (Comm SF) 938, which may be parts of the Communication Service Plane. The Comm CF 928 may be the control plane function for managing the Comm SF 938, communication sessions creation / configuration / releasing, and managing communication session context. The Comm SF 938 may be a user plane function for data transport. Comm CF 928 and Comm SF 938 may be considered as upgrades of SMF 646 and UPF 648, which were described with respect to a 5G system in Figure 6. The upgrades provided by the Comm CF 928 and the Comm SF 938 may enable service-aware transport. For legacy (e.g., 4G or 5G) data transport, SMF 646 and UPF 648 may still be used.
[0132] Two other such functions may include a Data Control Function (Data CF) 922 and Data Service Function (Data SF) 932 may be parts of the Data Service Plane. Data CF 922 may be a control plane function and provides functionalities such as Data SF 932 management, Data service creation / configuration / releasing, Data service context management, etc. Data SF 932 may be a user plane function and serve as the gateway between data service users (such as UE 902 and the various functions of the 6G CN 910) and data service endpoints behind the gateway. Specific functionalities may include include: parse data service user data and forward to corresponding data service endpoints, generate charging data, report data service status.
[0133] Another such function may be the Service Orchestration and Chaining Function (SOCF) 920, which may discover, orchestrate and chain up communication / computing / data services provided by functions in the network. Upon receiving service requests from users, SOCF 920 may interact with one or more of Comp CF 924, Comm CF 928, and Data CF 922 to identify Comp SF 936, Comm SF 938, and Data SF 932 instances, configure service resources, and generate the service chain, which could contain multiple Comp SF 936, Comm SF 938, and Data SF 932 instances and their associated computing endpoints. Workload processing and data movement may then be conducted within the generated service chain. The SOCF 920 may also responsible for maintaining, updating, and releasing a created service chain.
[0134] Another such function may be the service registration function (SRF) 914, which may act as a registry for system services provided in the user plane such as services provided by service endpoints behind Comp SF 936 and Data SF 932 gateways and services provided by the UE 902. The SRF 914 may be considered a counterpart of NRF 654, which may act as the registry for network functions.
[0135] Other such functions may include an evolved service communication proxy (eSCP) and service infrastructure control function (SICF) 926, which may provide service communication infrastructure for control plane services and user plane services. The eSCP may be related to the service communication proxy (SCP) of 5G with user plane service communication proxy capabilities being added. The eSCP is therefore expressed in two parts: eCSP-C 912 and eSCP-U 934, for control plane service communication proxy and user plane service communication proxy, respectively. The SICF 926 may control and configure eCSP instances in terms of service traffic routing policies, access rules, load balancing configurations, performance monitoring, etc.
[0136] Another such function is the AMF 944. The AMF 944 may be similar to 644, but with additional functionality. Specifically, the AMF 944 may include potential functional repartition, such as move the message forwarding functionality from the AMF 944 to the RAN 908.
[0137] Another such function is the service orchestration exposure function (SOEF) 918. The SOEF may be configured to expose service orchestration and chaining services to external users such as applications. The UE 902 may include an additional function that is referred to as a computing client service function (comp CSF) 904. The comp CSF 904 may have both the control plane functionalities and user plane functionalities, and may interact with corresponding network side functions such as SOCF 920, Comp CF 924, Comp SF 936, Data CF 922, and / or Data SF 932 for service discovery, request / response, compute task workload exchange, etc. The Comp CSF 904 may also work with network side functions to decide on whether a computing task should be run on the UE 902, the RAN 908, and / or an element of the 6G CN 910.
[0138] The UE 902 and / or the Comp CSF 904 may include a service mesh proxy 906. The service mesh proxy 906 may act as a proxy for service-to-service communication in the user plane. Capabilities of the service mesh proxy 906 may include one or more of addressing, security, load balancing, etc.
