[0002] This patent application claims the benefit of U.S. Patent Application No. 18 / 493,648, filed October 24, 2023, entitled “TECHNIQUES FORUSER EQUIPMENT FULL-DUPLEX OPERATION”, which has been assigned to the assignee of this application and is expressly incorporated herein by reference. Technical Field
[0003] The following text relates to wireless communication, including technologies for full-duplex operation of user equipment. Background Technology
[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, message sending and receiving, and broadcasting. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems (such as Long Term Evolution (LTE) systems, LTE-A Advanced (LTE-A) systems, or LTE-A Pro systems) and fifth-generation (5G) systems (which may be referred to as New Radio (NR) systems). These systems may employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal FDMA (OFDMA), or Discrete Fourier Transform Extended Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations, each supporting wireless communication for communication devices, which may be referred to as User Equipment (UE).
[0005] In some systems, certain devices (e.g., base stations, transceiver points, radio heads, or other network entities) can operate in full-duplex mode, where they use the same set of radio resources (e.g., the same or overlapping sets of time and frequency resources) to transmit and receive signals. Effective techniques for reliable communication when devices operate in full-duplex mode can help improve network efficiency, increase network throughput, and create an enhanced user experience. Summary of the Invention
[0006] The described technology relates to improved methods, systems, devices, and apparatuses for supporting full-duplex operation of user equipment (UE). For example, the described technology provides full-duplex communication at both the UE and a serving network entity, wherein the UE, the network entity, or both can dynamically change from full-duplex communication to half-duplex communication. In some aspects, UE full-duplex operation is achieved by providing a network entity full-duplex configuration of a set of symbols (or time slots) and a UE full-duplex configuration indicating some or all of the symbols in that set. For example, the UE full-duplex configuration may provide a corresponding full-duplex configuration to the network entity full-duplex configuration (e.g., a network entity configuration for downlink-uplink-downlink (D / U / D) communication for subband full-duplex (SBFD) communication corresponds to a UE configuration for D / U / D). In cases where the UE would benefit from a switch to half-duplex communication (e.g., due to self-interference at the UE), the network entity may send an indication to switch one or more symbols to a half-duplex configuration. In some respects, a half-duplex configuration may correspond to the indicated half-duplex configuration, in which both the network entity and the UE operate in a half-duplex configuration. In other respects, a half-duplex configuration may correspond to a full-duplex configuration of the network entity, in which the UE operates in half-duplex and the network operates in full-duplex (e.g., sending downlink communication to a first UE and receiving uplink communication from a second UE).
[0007] In some aspects, dynamic full-duplex signaling indicating the updated configuration of one or more symbols can be provided via downlink control information (DCI) (such as scheduled or unscheduled DCI). Additionally or alternatively, dynamic full-duplex signaling indicating the updated configuration of one or more symbols can be provided via a media access control (MAC) control element (CE). The indication of an update to one or more symbols can be provided via a bitmap, a predefined pattern ID, an offset / length identifying the updated symbol, or any combination thereof. In some aspects, the update of a full-duplex symbol can be initiated based on the time of receipt of the indication, based on the time of acknowledgment of the indication, based on the configuration time (e.g., configured in radio resource control signaling), based on the time indicated by a UE capability message, or any combination thereof. In some aspects, the update of the full-duplex configuration of one or more symbols can be applied to one or more component carriers.

[0054] In some systems, one or more devices (such as network entities or user equipment (UEs)) can operate in full-duplex mode, in which they use the same set of radio resources (e.g., the same set of time and frequency resources) to transmit and receive signals. When devices operate in full-duplex mode, concurrent transmission and reception can lead to self-interference of the transmitted signals with the signals to be received concurrently, cross-link interference (CLI) from other transmitters, or both. This interference can reduce the likelihood of successful reception and decoding of communications, and various techniques can be implemented to mitigate this interference in order to enhance the reliability of communications (e.g., higher transmit power during full-duplex operation periods, reduced decoding rates or modulation orders, beam selection to avoid interfering beams, or any combination thereof).
[0055] In some deployments, full-duplex communication technology can provide full-duplex communication at the network entity and half-duplex communication at the UE. Therefore, the network entity can send downlink communication to a first UE while simultaneously receiving uplink communication from a second UE. In other deployments, one or more UEs, or both the UE and the network entity, can operate using full-duplex communication. Furthermore, some deployments can use Subband Full-Duplex (SBFD), where a portion of the bandwidth can be configured for full-duplex communication. In SBFD, the bandwidth portion can be divided into downlink frequency resources and uplink frequency resources. For example, one or more frequency subbands can be used for uplink communication, and one or more other frequency subbands can be used for downlink communication. In some cases, the uplink and downlink frequency subbands can be non-overlapping, although techniques as discussed herein can be used where the downlink and uplink frequency subbands can partially or completely overlap.
[0056] As discussed, interference that can affect communication reliability may exist in full-duplex communication in some cases. For example, clutter near a full-duplex device may cause reflections of transmitted signals, which may interfere with the reception of concurrent signals to be received at the full-duplex device, potentially leading to self-interference that could affect communication reliability. Furthermore, where a UE can concurrently transmit and receive signals in the same frequency band using full-duplex communication, UE mobility may cause variations in interference that are more observable at network entities (e.g., at the radio head end) that remain stationary. Therefore, in cases where a UE operates in full-duplex mode, switching to half-duplex operation may be beneficial, such as if self-interference or cross-link interference exists at the UE due to mobility or environmental changes that cause variations in interference at the UE.
[0057] Based on the various aspects discussed herein, effective techniques are provided for implementing UE full-duplex operation and fallback to half-duplex operation, thereby enhancing communication efficiency and reliability. In some aspects, both the UE and the network entity can be configured for full-duplex communication, where communication is transmitted and received concurrently using the same frequency band. In some aspects, dynamic UE full-duplex operation is achieved by providing a network entity full-duplex configuration of a set of symbols (or time slots, where the description associated with the symbols also applies to the time slots), and a UE full-duplex configuration indicating some or all of the symbols of the network entity full-duplex configuration. In some aspects, the UE full-duplex configuration can provide a corresponding full-duplex configuration to the network entity full-duplex configuration (e.g., a network entity sub-band full-duplex (SBFD) configuration for downlink / uplink / downlink (D / U / D) can correspond to a UE SBFD configuration for D / U / D). In cases where the UE would benefit from a handover to half-duplex communication (e.g., due to self-interference at the UE), the network entity can send an indication to switch one or more symbols to a half-duplex configuration. Depending on various aspects, different alternatives are provided for UE behavior when switching to half-duplex operation. For example, if the half-duplex symbol configuration (e.g., the half-duplex configuration provided in the Time Division Duplex (TDD) slot format indication of which symbols in the defined slots are uplink, downlink, or flexible symbols) indicates that the symbol is a downlink (D) symbol, then the UE can switch from a full-duplex configuration to a half-duplex downlink configuration for that symbol, and if the half-duplex configuration is a flexible symbol, then the UE can switch to a flexible or downlink half-duplex configuration depending on the network entity's full-duplex configuration. In some aspects, dynamic signaling can be provided to the UE to indicate an updated configuration of one or more symbols, such as through downlink control information (DCI) (e.g., scheduled or unscheduled DCI), media access control (MAC) control elements (CE), or any combination thereof. The indication of an updated UE full-duplex symbol can be provided through a bitmap, a predefined mode ID, an offset / length identifying the updated symbol, or any combination thereof. Additionally or alternatively, updates to the UE full-duplex symbol configuration may be initiated based on the time of receipt of the indication, the time of acknowledgment of the indication, the Radio Resource Control (RRC) configuration, the time indicated by the UE capability message, or any combination thereof. In some aspects, the UE may be configured with two or more component carriers (CCs) configured for UE full-duplex communication, and updates to the UE full-duplex configuration may apply to one or more CCs.
[0058] Therefore, the techniques discussed herein can provide enhanced resource utilization and communication efficiency associated with full-duplex communication at the UE. Such techniques can help improve the reliability of transmissions in full-duplex communication (e.g., to allow the UE to switch to half-duplex communication in the event of increased interference). Thus, such techniques enhance network efficiency, reliability, throughput, and power consumption (e.g., by reducing retransmissions) by reducing overhead, and provide an enhanced user experience.
[0059] The aspects of this disclosure are first described in the context of a wireless communication system. These aspects are further illustrated and described with reference to full-duplex and half-duplex operation modes and configurations, process flows, apparatus diagrams, system diagrams, and flowcharts relating to the technology used for full-duplex operation of the UE.
[0060] Figure 1 An example of a wireless communication system 100 supporting technologies for full-duplex operation of a UE according to one or more aspects of this disclosure is shown. The wireless communication system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating under other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.
[0061] Network entity 105 may be distributed across a geographical area to form wireless communication system 100, and may include devices employing different forms or having different capabilities. In various examples, network entity 105 may be referred to as a network element, mobility element, radio access network (RAN) node, or network equipment, etc. In some examples, network entity 105 and UE 115 may wirelessly communicate via one or more communication links 125 (e.g., radio frequency (RF) access links). For example, network entity 105 may support coverage area 110 (e.g., a geographical coverage area) within which UE 115 and network entity 105 may establish one or more communication links 125. Coverage area 110 may be an example of a geographical area within which network entity 105 and UE 115 may support the transmission of signals according to one or more radio access technologies (RATs).
[0062] UE 115 can be distributed throughout the coverage area 110 of wireless communication system 100, and each UE 115 can be stationary or mobile, or stationary and mobile at different times. UE 115 can be devices in different forms or with different capabilities. Figure 1Some example UE 115s are illustrated herein. The UE 115 described herein can be able to support various types of devices, such as... Figure 1 The other UE 115 or network entity 105 shown communicates.
[0063] As described herein, nodes of the wireless communication system 100 (which may be referred to as network nodes or wireless nodes) may be network entity 105 (e.g., any network entity described herein), UE 115 (e.g., any UE described herein), network controller, apparatus, device, computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, a node may be UE 115. Alternatively, a node may be network entity 105. Furthermore, a first node may be configured to communicate with a second or third node. In one aspect of this example, the first node may be UE 115, the second node may be network entity 105, and the third node may be UE 115. In another aspect of this example, the first node may be UE 115, the second node may be network entity 105, and the third node may be network entity 105. In other aspects of this example, the first node, the second node, and the third node may be different from these examples. Similarly, references to UE 115, network entity 105, device, equipment, computing system, etc., may include disclosures of UE 115, network entity 105, device, equipment, computing system, etc., as nodes. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that a first node is configured to receive information from a second node.
[0064] In some examples, network entity 105 may communicate with core network 130, or communicate with each other, or both. For example, network entity 105 may communicate with core network 130 via one or more backhaul communication links 120 (e.g., according to S1, N2, N3, or other interface protocols). In some examples, network entities 105 may communicate with each other directly (e.g., directly between network entities 105) or indirectly (e.g., via core network 130) via backhaul communication links 120 (e.g., according to X2, Xn, or other interface protocols). In some examples, network entities 105 may communicate with each other via midhaul communication link 162 (e.g., according to midhaul interface protocol) or fronthaul communication link 168 (e.g., according to fronthaul interface protocol) or any combination thereof. Backhaul communication link 120, midhaul communication link 162, or fronthaul communication link 168 may be or include one or more wired links (e.g., electrical links, fiber optic links), one or more wireless links (e.g., radio links, wireless optical links), etc., or various combinations thereof. UE 115 can communicate with core network 130 via communication link 155.
[0065] One or more network entities in network entity 105 described herein may include or be referred to as base station 140 (e.g., transceiver base station, radio base station, NR base station, access point, radio transceiver, node B, eNodeB (eNB), next-generation node B or gigabit node B (any of which may be referred to as gNB), 5G NB, next-generation eNB (ng-eNB), home node B, home evolution node B, or other suitable terms). In some examples, network entity 105 (e.g., base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture that may be configured to utilize a protocol stack that is physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as base station 140).
[0066] In some examples, network entity 105 may be implemented in a decomposed architecture (e.g., a decomposed base station architecture, a decomposed RAN architecture) that can be configured to utilize protocol stacks physically or logically distributed across two or more network entities 105, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN)). For example, network entity 105 may include one or more of the following: a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN intelligent controller (RIC) 175 (e.g., a near real-time RIC, a non-real-time RIC), a service management and orchestration (SMO) 180 system, or any combination thereof. 170 may also be referred to as a radio headend, intelligent radio headend, remote radio headend (RRH), remote radio unit (RRU), or transmit / receive point (TRP). One or more components of network entity 105 in a decomposed RAN architecture may be co-located, or one or more components of network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities 105 in a decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).
[0067] The functional splitting among CU 160, DU 165, and RU 170 is flexible and can support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at CU 160, DU 165, or RU 170. For example, a protocol stack functional splitting can be used between CU 160 and DU 165, allowing CU 160 to support one or more layers of the protocol stack, and DU 165 to support one or more different layers of the protocol stack. In some examples, CU 160 can host higher protocol layer (e.g., Layer 3 (L3), Layer 2 (L2)) functionalities and signaling (e.g., Radio Resource Control (RRC), Serving Data Adaptation Protocol (SDAP), Packet Data Convergence Protocol (PDCP)). CU 160 can connect to one or more DU 165 or RU 170, and one or more DU 165 or RU 170 can host lower protocol layers, such as Layer 1 (L1) (e.g., Physical (PHY) layer) or L2 (e.g., Radio Link Control (RLC) layer, Medium Access Control (MAC) layer) functionality and signaling, and each can be at least partially controlled by CU 160. Additionally or alternatively, a protocol stack functional split can be employed between DU 165 and RU 170, such that DU 165 can support one or more layers of the protocol stack, and RU 170 can support one or more different layers of the protocol stack. DU 165 can support one or more different cells (e.g., via one or more RU 170). In some cases, functional decomposition between CU 160 and DU 165, or between DU 165 and RU 170, can be performed within the protocol layer (e.g., some functions of the protocol layer can be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer can be performed by different of CU 160, DU 165, or RU 170). CU 160 can be further functionally decomposed into CU control plane (CU-CP) functions and CU user plane (CU-UP) functions. CU 160 can be connected to one or more DU 165 via midhaul communication link 162 (e.g., F1, F1-c, F1-u), and DU 165 can be connected to one or more RU 170 via fronthaul communication link 168 (e.g., open fronthaul (FH) interface). In some examples, the midhaul communication link 162 or the fronthaul communication link 168 may be implemented based on the interfaces (e.g., channels) between the layers of the protocol stack, which are supported by the corresponding network entities 105 communicating via such communication links.
[0068] In a wireless communication system (e.g., wireless communication system 100), the infrastructure and spectrum resources for radio access can support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB node 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as donor entities or IAB donors. One or more DU 165s or one or more RU 170s may be partially controlled by one or more CU 160s associated with donor network entity 105 (e.g., donor base station 140). One or more donor network entities 105 (e.g., IAB donors) may communicate with one or more additional network entities 105 (e.g., IAB node 104) via supported access and backhaul links (e.g., backhaul communication link 120). IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by a DU 165 of a coupled IAB donor. The IAB-MT may include a separate set of antennas for relaying communication with UE 115, or may share the same antennas (e.g., those of RU 170) for access to IAB node 104 via DU 165 of IAB node 104. (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, IAB node 104 may include a DU 165 that supports communication links with additional entities (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of the access network. In such cases, one or more components of the decomposed RAN architecture (e.g., one or more IAB nodes 104 or components of IAB node 104) may be configured to operate according to the techniques described herein.
[0069] In the context of applying the techniques described herein to a decomposed RAN architecture, one or more components of the decomposed RAN architecture can be configured to support the techniques described herein for UE full-duplex operation. For example, some operations described as being performed by UE 115 or network entity 105 (e.g., base station 140) may additionally or alternatively be performed by one or more components of the decomposed RAN architecture (e.g., IAB node 104, DU 165, CU 160, RU 170, RIC 175, SMO 180).
[0070] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, wherein "device" may also be referred to as a cell, station, terminal, or client, etc. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, etc., which may be implemented in various objects such as appliances or vehicles, meters, etc.
[0071] The UE 115 described herein can communicate with various types of devices, such as other UEs 115 that may sometimes act as relays, as well as network entities 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 As shown.
[0072] UE 115 and network entity 105 can wirelessly communicate with each other via one or more communication links 125 (e.g., access links) using resources associated with one or more carriers. The term "carrier" can refer to a set of RF spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of the RF spectrum band (e.g., a bandwidth portion (BWP)) operating according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating carrier operation, user data, or other signaling. Wireless communication system 100 may support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 may be configured to utilize multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers. Communication between network entity 105 and other devices can refer to communication between these devices and any part of network entity 105 (e.g., entity, sub-entity). For example, the terms “send,” “receive,” or “communicate” when referring to network entity 105 can refer to any part of the RAN’s network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) communicating with another device (e.g., directly or via one or more other network entities 105).
[0073] In some examples, such as in carrier aggregation configurations, a carrier may also have acquisition signaling or control signaling to coordinate the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute RF Channel Number (EARFCN)) and may be identified according to a channel grating used for discovery by UE 115. A carrier may operate in standalone mode, in which case initial acquisition and connection can be performed by UE 115 via that carrier, or the carrier may operate in non-standalone mode, in which case different carriers (e.g., the same or different radio access technologies) are used to anchor the connection.
[0074] The communication link 125 shown in the wireless communication system 100 may include downlink transmission (e.g., forward link transmission) from network entity 105 to UE 115, uplink transmission (e.g., return link transmission) from UE 115 to network entity 105, or both, as well as other transmission configurations. A carrier may carry downlink communication or uplink communication (e.g., in FDD mode), or may be configured to carry both downlink and uplink communication (e.g., in TDD mode).
[0075] A carrier may be associated with a specific bandwidth of the RF spectrum, and in some examples, the carrier bandwidth may be referred to as the carrier or the “system bandwidth” of the wireless communication system 100. For example, the carrier bandwidth may be one bandwidth in a set of bandwidths for a particular radio access technology (e.g., 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, 40 MHz, or 80 MHz). Devices of the wireless communication system 100 (e.g., network entity 105, UE 115, or both) may have hardware configurations that support communication using a specific carrier bandwidth, or may be configured to support communication using one carrier bandwidth in a set of carrier bandwidths. In some examples, the wireless communication system 100 may include network entity 105 or UE 115 that supports concurrent communication using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate using a portion (e.g., subband, BWP) or all of the carrier bandwidth.
[0076] The signal waveform transmitted via a carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform extended OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element may refer to a resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, in which case the symbol period and subcarrier spacing may be inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the decoding rate of the modulation scheme, or both), such that a relatively high number of resource elements (e.g., in the transmission duration) and a relatively high modulation scheme order may correspond to a relatively high communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communication with UE 115.
[0077] It can support one or more sets of parameters for a carrier, and the set of parameters may include subcarrier spacing ( (and cyclic prefix). A carrier can be divided into one or more BWPs with the same or different sets of parameters. In some examples, multiple BWPs can be used to configure UE 115. In some examples, a single BWP of a carrier can be active at a given time, and the communication of UE 115 can be constrained to one or more active BWPs.
[0078] The time interval for network entity 105 or UE 115 can be expressed as a multiple of a basic time unit, such as the sampling period. seconds, of which It can represent the supported subcarrier spacing, and This can represent the supported Discrete Fourier Transform (DFT) size. The time interval of the communication resources can be organized according to radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).
[0079] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may (e.g., in the time domain) be divided into subframes, and each subframe may be further divided into a number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of symbol periods (e.g., depending on the length of the cyclic prefix appended to each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple micro-time slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., The duration of a symbol period is associated with a (number) sampling period. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.
[0080] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).
[0081] Depending on the technology, carriers can be used to multiplex physical channels for communication. One or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used, for example, to multiplex physical control channels and physical data channels for signaling via a downlink carrier. The control region (e.g., control resource set (CORESET)) of the physical control channel can be defined by a set of symbol periods and can extend across the system bandwidth of the carrier or a subset of that bandwidth. One or more control regions (e.g., CORESET) can be configured for a set of UEs 115. For example, one or more UEs in UE 115 can monitor or search for control regions to obtain control information based on one or more search space sets, and each search space set can include one or more control channel candidates in one or more aggregation levels arranged in a concatenated manner. The aggregation level of control channel candidates can refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space set may include: a common search space set configured to transmit control information to multiple UEs 115, and a UE-specific search space set used to transmit control information to a specific UE 115.
[0082] In some examples, network entity 105 (e.g., base station 140, RU 170) may be mobile, and thus provide communication coverage to mobile coverage areas 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of network entities 105 use the same or different radio access technologies to provide coverage for various coverage areas 110.
[0083] Wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC). UE 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communication may include private or group communication and may be supported by one or more services, such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritizing services, and such services may be used for public safety or general business applications. The terms “ultra-reliable,” “low-latency,” and “ultra-reliable low-latency” are used interchangeably herein.
[0084] In some examples, UE 115 may be configured to support direct communication with other UE 115s via device-to-device (D2D) communication link 135 (e.g., according to peer-to-peer (P2P), D2D, or sidelink protocols). In some examples, one or more UE 115s performing D2D communication in a group may be within the coverage area 110 of network entity 105 (e.g., base station 140, RU 170), which may support aspects of such D2D communication configured (e.g., scheduled by network entity 105). In some examples, one or more UE 115s in such a group may be outside the coverage area 110 of network entity 105, or may otherwise be unable or not configured to receive transmissions from network entity 105. In some examples, the group of UE 115s communicating via D2D communication may support a one-to-many (1:M) system, where each UE 115 transmits to each of the other UE 115s in the group. In some examples, network entity 105 may facilitate the scheduling of resources used for D2D communication. In other examples, D2D communication may be performed between UEs 115 without involving network entity 105.
[0085] Core network 130 provides user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), access and mobility management function (AMF)) for managing access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), packet data network (PDN) gateway (P-GW), or user plane function (UPF)) for routing packets or interconnecting to external networks. The control plane entity manages non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by network entity 105 (e.g., base station 140) associated with core network 130. User IP packets can be transferred through user plane entities, which provide IP address allocation and other functions. User plane entities can connect to one or more network operator IP services 150. IP services 150 may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.
[0086] Wireless communication system 100 can operate using one or more frequency bands in the range of 300 MHz to 300 GHz. Generally, the area from 300 MHz to 3 GHz is referred to as the Ultra High Frequency (UHF) band or decimeter band because the wavelength range is approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clusters), but these waves are sufficient to penetrate structures so that macrocells can provide service to UE 115 located indoors. Compared to communication using smaller frequencies and longer waves in the High Frequency (HF) or Very High Frequency (VHF) portions of the spectrum below 300 MHz, communication using UHF waves can be associated with smaller antennas and shorter ranges (e.g., less than 100 km).
[0087] Wireless communication system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, wireless communication system 100 may use unlicensed bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band) to employ Licensed Assisted Access (LAA), LTE Unlicensed (LTE-U) radio access technology, or NR technology. When operating with unlicensed RF spectrum, devices such as network entity 105 and UE 115 may employ carrier sensing for collision detection and avoidance. In some examples, operation using unlicensed bands may be combined with component carriers operating with licensed bands based on carrier aggregation configurations (e.g., LAA). Operation using unlicensed spectrum may include downlink transmission, uplink transmission, P2P transmission, or D2D transmission, etc.
[0088] Network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of network entity 105 or UE 115 may be located within one or more antenna arrays or antenna panels, which can support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly (such as an antenna tower). In some examples, the antennas or antenna arrays associated with network entity 105 may be located at different geographical locations. Network entity 105 may include an antenna array having a collection of multiple rows and columns of antenna ports that network entity 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may include one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals transmitted via the antenna ports.
[0089] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., network entity 105, UE 115) to shape or guide an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating along a specific orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to the signals transmitted via the antenna elements may include applying amplitude shifts, phase shifts, or both to the signals carried via the antenna elements associated with the device. The adjustments associated with each of these antenna elements may be defined by a beamforming weight set associated with a specific direction (e.g., relative to the antenna array of the transmitting or receiving device or relative to some other direction).
[0090] The wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or PDCP layer can be IP-based. The RLC layer performs packet segmentation and reassembly for transmission via logical channels. The MAC layer performs priority handling and multiplexing of logical channels to transport channels. The MAC layer can also implement error detection, error correction, or both to support retransmission and improve link efficiency. In the control plane, the RRC layer provides the establishment, configuration, and maintenance of RRC connections between the UE 115 and network entity 105 or core network 130 that support user plane data radio bearers. The PHY layer maps transport channels to physical channels.
[0091] UE 115 and network entity 105 can support data retransmission to increase the likelihood of successful data reception. Hybrid Automatic Repeat Request (HARQ) feedback is a technique used to increase the likelihood of correctly receiving data via communication links (e.g., communication link 125, D2D communication link 135). HARQ may include a combination of error detection (e.g., using Cyclic Redundancy Check (CRC)), forward error correction (FEC), and retransmission (e.g., Automatic Repeat Request (ARQ)). HARQ can improve throughput at the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, the device may support same-slot HARQ feedback, in which case the device may provide HARQ feedback in a specific time slot for data received via a previous symbol in that time slot. In some other examples, the device may provide HARQ feedback in subsequent time slots or according to a different time interval.
[0092] In some cases, full-duplex communication can be configured at both UE 115 and the serving network entity 105, where UE 115, network entity 105, or both can dynamically change from full-duplex communication to half-duplex communication. In some aspects, UE full-duplex operation is achieved by providing a network entity full-duplex configuration for a set of symbols (or time slots) and a UE full-duplex configuration indicating some or all of the symbols in that set. For example, the UE full-duplex configuration can provide a corresponding full-duplex configuration to the network entity full-duplex configuration (e.g., the network entity configuration for D / U / D used for SBFD communication corresponds to the UE configuration for D / U / D). In cases where UE 115 would benefit from a switch to half-duplex communication (e.g., due to self-interference at UE 115), network entity 105 can send an indication to switch one or more symbols to a half-duplex configuration. In some aspects, the half-duplex configuration can correspond to the indicated half-duplex configuration, where both network entity 105 and UE 115 operate in half-duplex configuration. In other respects, the half-duplex configuration can correspond to the full-duplex configuration of network entity 105, wherein UE 115 operates in half-duplex and network entity 105 operates in full-duplex configuration.
[0093] Figure 2 An example of a wireless communication system 200 supporting techniques for full-duplex operation of a UE according to one or more aspects of this disclosure is shown. The wireless communication system 200 may include a network entity 105-a and a UE 115-a, which may be represented as shown in reference... Figure 1 Examples of network entity 105 and UE 115 described.
[0094] In this example, UE 115-a can communicate with network entity 105-a via downlink transmissions on one or more downlink subbands 205-a and uplink transmissions on one or more uplink subbands 205-b. These downlink and uplink transmissions can use the same component carriers utilizing TDD, or they can use different carriers (e.g., using FDD). Figure 2 In the example, for at least some communications, network entity 105-a and UE 115-a can operate in full-duplex mode, in which a first resource set can be used for both uplink and downlink communications. For example, downlink transmission to UE 115-a can be transmitted simultaneously with uplink transmission received from UE 115-a (e.g., simultaneous communication using the same frequency band).
[0095] As discussed herein, full-duplex communication (e.g., SBFD or in-band full-duplex (IBFD)) can be performed at network entity 105-a and UE 115-a, wherein the full-duplex configuration of one or more symbols can be switched to a half-duplex configuration at UE 115-a, network entity 105-a, or both. In some aspects, network entity 105-a can provide configuration information 210 to UE 115-a. Configuration information 210 provides both network full-duplex configuration and UE full-duplex configuration. In some aspects, configuration information 210 can provide a fallback to half-duplex operation at UE 115-a, network entity 105-a, or both based on dynamic signaling that can update the configuration of one or more symbols. In some aspects, the UE full-duplex configuration information and the associated fallback behavior can be based on capability indication 215 provided by UE 115-a. In some respects, UE 115-a and network entity 105-a can communicate according to their respective full-duplex configurations, wherein downlink transmission 225 can transmit concurrently with uplink transmission 230 according to a full-duplex configuration (such as an SBFD configuration where CC 235 can have two downlink subbands 205-b and one uplink subband 205-a). According to the various aspects discussed herein, an update indication 220 indicating a change in configuration of one or more symbols can be sent from network entity 105-a to UE 115-a, and the associated downlink transmission 225 and uplink transmission 230 can be communicated according to the changed configuration. Figures 3 to 6 Examples of full-duplex configuration and operation based on update instruction 220 are provided for various aspects.
[0096] Figure 3Examples of half-duplex and full-duplex operation modes 300 supporting technologies for full-duplex operation of a UE according to one or more aspects of this disclosure are shown. The half-duplex and full-duplex operation modes 300 can provide communication between network entities 105-b, 105-c, and 105-d and UEs 115-b, 115-c, 115-d, and 115-e, which can represent as shown in reference... Figure 1 and Figure 2 Examples of network entity 105 and UE 115 described.
[0097] In the first example 305, a half-duplex mode is illustrated, in which both network entity 105-b and UE 115-b use downlink or uplink beam 330 to perform half-duplex communication. In the first example 305, network entity 105-b may use a first antenna panel 320 (or a subset of antenna elements of the antenna panel), and UE 115-b may use a UE antenna panel 325 to transmit or receive using downlink or uplink beam 330. This type of half-duplex mode can use an entire bandwidth portion for communication (e.g., the entire frequency bandwidth of CC).
[0098] In the second example 310, network entity 105-c can operate in full-duplex mode to concurrently communicate with the first UE 115-c using downlink beam 345 and with the second UE 115-d using uplink beam 355. Depending on the full-duplex configuration of network entity 105-c, each of the first UE 115-c and the second UE 115-d can operate in half-duplex mode using a portion of the BWP, which is configured for uplink or downlink communication. For example, network entity 105-c can operate in SBFD mode, where the BWP has three subbands in a downlink / uplink / downlink (D / U / D) or flexible / uplink / flexible (F / U / F) configuration (e.g., this could be referred to as mode 1). In other examples, SBFD mode can have a BWP configured with two subbands in a downlink / uplink (D / U) or flexible / uplink (F / U) configuration (e.g., this could be referred to as mode 2). In some cases, a guard band with a specific number of resource blocks (RBs) may exist between the downlink subband and the uplink subband. While the various examples discussed herein use SBFD, the techniques provided herein are also applicable to IBFD, where the downlink and uplink bandwidths partially or completely overlap. In the second example 310, network entity 105-c may use a first antenna panel 335-a (or a first subset of antenna elements from one or more antenna panels) for downlink communication to a first UE 115-c, and may use a second antenna panel 335-b (or a second subset of antenna elements from one or more antenna panels) for uplink communication from a second UE 115-d. In this example, each of the first UE 115-c and the second UE 115-d operates in half-duplex mode, where the first UE 115-c uses the first UE antenna panel 340, and the second UE 115-d uses the second UE antenna panel 350.
[0099] In the third example 315, network entity 105-d can operate in full-duplex mode to concurrently transmit uplink and downlink communications with full-duplex UE 115-e using downlink beam 370 and uplink beam 375. In this third example 315, both full-duplex UE 115-e and network entity 105-d can operate in SBFD mode, where network entity 105-c can use a first antenna panel 360-a (or a first subset of antenna elements from one or more antenna panels) for downlink communication to full-duplex UE 115-e, and can use a second antenna panel 360-b (or a second subset of antenna elements from one or more antenna panels) for uplink communication from full-duplex UE 115-e. In this example, full-duplex UE 115-e can use the first subset 365-a of antenna elements for downlink communication and the second subset 365-b of antenna elements for uplink communication. In some cases, at the full-duplex UE 115-e, different subsets of antenna elements 365-a and 365-b can be on the same antenna panel or on different antenna panels.
[0100] Such full-duplex technology can be implemented in TDD carriers or based on in-band carrier aggregation (CA) and can increase the uplink duty cycle. This increased uplink duty cycle can lead to, for example, reduced latency (e.g., the possibility of transmitting uplink signals in uplink subbands that would otherwise be downlink-only or flexible symbols, or receiving downlink signals in downlink subbands in symbols that would otherwise be uplink-only, thus reducing latency), improved uplink coverage, enhanced system capacity, enhanced resource utilization, enhanced spectral efficiency, flexible and dynamic uplink / downlink resource adaptation based on real-time uplink / downlink traffic, or any combination thereof. Based on the various aspects discussed herein, the full-duplex communication technology between UE 115 and network entity 105 can be dynamically changed based on the current conditions at UE 115, network entity 105, or both, which can further enhance the reliability and efficiency of communication when configuring full-duplex communication.
[0101] Figure 4 An example of a network and UE configuration 400 supporting technologies for full-duplex operation of a UE according to one or more aspects of this disclosure is shown. Figure 4 The example can be used for full-duplex communication between one or more UEs and network entities, which can be as shown in the reference. Figures 1 to 3 Examples of UE 115 and network entity 105 are described. In some examples, the network entity may send configuration information to one or more UEs instructing them to use full-duplex communication technology.
[0102] exist Figure 4 In the example, the network entity can provide a half-duplex configuration 405 indicating the half-duplex format used for the symbol set. The half-duplex configuration 405 can provide a slot format index, for example, that is mapped to the D / U / F format used for the symbol set (e.g., a slot format indication as described in section 11.1.1 of 3GPP TS 38.213). The half-duplex configuration 405 may be referred to herein as a legacy half-duplex configuration. Figure 4 The example illustrates a five-symbol half-duplex configuration 405, where the first four symbols are configured as downlink symbols and the fifth symbol is configured as an uplink symbol. It should be understood that... Figure 4 and Figure 5 The examples discussed herein are provided for discussion and illustration purposes, and the techniques discussed herein can be used for many different combinations of uplink and downlink symbols, and many different combinations of SBFD in the IBFD symbol format. In some aspects, a network entity can provide a network full-duplex configuration (e.g., an SBFD configuration indicating the uplink and downlink subbands configured for full-duplex communication at the network entity). The network entity can activate the network full-duplex configuration in network full-duplex configuration activation 410, which can indicate the set of symbols on which the network SBFD configuration is activated. Figure 4 In the example, the network SBFD configuration is activated on the first four symbols.
[0103] Depending on some aspects, a network entity may provide a network-UE full-duplex configuration 415 to a served UE (e.g., a first UE), which may activate a first UE SBFD configuration 420 for one or more symbols in a set of symbols configured for network SBFD. Figure 4 In the example, the first two symbols can be activated by the network and UE full-duplex configuration 415 for UE SBFD communication. In this example, the first UE SBFD configuration 420 can enable the first UE to perform full-duplex communication according to the D / U / DSBFD configuration, wherein the first UE can concurrently transmit uplink communication using the uplink subband while receiving downlink communication using the downlink subband. In some cases, the UE SBFD configuration can be matched with the network SBFD configuration, allowing the serving network entity to concurrently transmit and receive uplink and downlink communication with the first UE.
[0104] Depending on various factors, a network entity may send a dynamic UE SBFD indication 425, indicating that a first UE will switch away from the UE SBFD configuration and switch to a different configuration for one or more symbols. In some cases, the dynamic UE SBFD indication 425 may be sent by the network entity in response to a measurement report from the UE indicating the presence of interference. In other cases, the network entity may send the dynamic UE SBFD indication 425 based on a NACK pattern, which may be associated with certain symbols that are receiving interference (e.g., due to the presence of periodic CLI). Figure 4 In the example, the dynamic UE SBFD indication 425 can instruct the UE to fall back to half-duplex operation for the first two symbols, where the UE will otherwise use full-duplex according to the network and UE full-duplex configuration 415. In some cases, both the UE and the network entity can fall back to half-duplex communication, as illustrated at 430, where the configuration of the legacy half-duplex configuration 405 is used for the associated symbols. In other cases, the network entity can continue to operate according to the network full-duplex configuration, and the first UE can fall back to half-duplex communication to receive downlink communication on the downlink subband of the network full-duplex configuration, as indicated at 435, where the second UE can operate in half-duplex and use the uplink subband of the network full-duplex configuration, as indicated at 440.
[0105] Therefore, techniques such as those described herein can support dynamic UE SBFD operation, allowing the UE to update its UE SBFD configuration to a legacy half-duplex configuration. Such techniques can, for example, provide a fallback to half-duplex mode if, in the case of conditional SBFD UE capability, the UE may wish to revert to half-duplex mode if its leaked self-interference or clutter increases due to environmental changes or mobility. This dynamic SBFD can also provide more efficient adaptation to uplink and downlink resource requirements based on traffic load.
[0106] In some respects, UE behavior can differ based on symbol (or time slot) configuration. For example, if the UE SBFD symbol is configured on a legacy half-duplex downlink symbol, the UE SBFD symbol can (1) fall back to the legacy D symbol, where both the network entity and the UE operate in half-duplex mode for that symbol, or (2) fall back to the network entity SBFD symbol format, where the UE can operate in half-duplex mode and the network entity operates in SBFD mode. In some cases, the UE can send capability signaling indicating whether the UE supports full-duplex operation and which fallback behavior the UE supports.
[0107] Figure 5 Another example of a network and UE configuration 500 supporting technologies for full-duplex operation of a UE, according to one or more aspects of this disclosure, is shown. Figure 5 The example can be used for full-duplex communication between one or more UEs and network entities, which can be as shown in the reference. Figures 1 to 3 Examples of UE 115 and network entity 105 are described. In some examples, the network entity may send configuration information to one or more UEs instructing them to use full-duplex communication technology.
[0108] exist Figure 5 In the example, the network entity can provide a half-duplex configuration 505 indicating the half-duplex format used for the symbol set. The half-duplex configuration 505 can provide a slot format index, for example, that is mapped to a D / U / F format used for the symbol set, similar to a reference. Figure 4 The subject of discussion. Figure 5 The example illustrates a five-symbol half-duplex configuration 505, where the first four symbols are configured as flexible symbols, and the fifth symbol is configured as an uplink symbol. In some aspects, network entities can provide a network full-duplex configuration (e.g., an SBFD configuration indicating the uplink and downlink subbands configured for full-duplex communication at the network entity). A network entity can activate a network full-duplex configuration in network full-duplex configuration activation 510, which can indicate the set of symbols on which the network SBFD configuration is activated. Figure 5 In the example, the network SBFD configuration is activated on the first four symbols.
[0109] Depending on some aspects, a network entity may provide a network-UE full-duplex configuration 515 to a served UE (e.g., a first UE), which may activate a first UE SBFD configuration 520 for one or more symbols in a set of symbols configured for network SBFD. Figure 5 In the example, the first two symbols can be activated by the network and UE full-duplex configuration 515 for UE SBFD communication. In this example, the first UE SBFD configuration 520 can enable the first UE to perform full-duplex communication according to the F / U / FSBFD configuration or the D / U / D SBFD configuration, wherein the first UE can concurrently send uplink communication using the uplink subband while communicating using the downlink or flexible subband according to the downlink or flexible format. In some cases, the UE SBFD configuration can be matched with the network SBFD configuration, allowing the serving network entity to concurrently send and receive uplink and downlink communication with the first UE.
[0110] Similarly, as referenced Figure 4 The network entity discussed can send a dynamic UE SBFD indication 525, which indicates that a first UE will switch out of the UE SBFD configuration and switch to a different configuration of one or more symbols. Figure 5 In the example, the dynamic UE SBFD indication 525 can instruct the UE to fall back to half-duplex operation for the first two symbols, where the UE will otherwise use full-duplex according to the network and UE full-duplex configuration 515. In some cases, both the UE and the network entity can fall back to half-duplex communication, as illustrated at 530, where the downlink or flexible configuration of the legacy half-duplex configuration 505 is used for the associated symbol. In other cases, the network entity can continue to operate according to the network full-duplex configuration (e.g., D / U / D), and the first UE can fall back to half-duplex communication for the indicated symbol, as indicated at 535, where the second UE can operate in half-duplex and use the uplink subband of the network full-duplex configuration, as indicated at 540.
[0111] For example, if the UE SBFD symbol is configured on a legacy half-duplex flexible symbol, and D / U / D or D / U is configured for network entity SBFD operation and UE SBFD operation on the flexible symbol, then the UE SBFD symbol can (1) fall back to the legacy D symbol, where both the network entity and the UE operate in half-duplex mode for that symbol; (2) fall back to the legacy F symbol, where both the network entity and the UE operate in half-duplex mode for that symbol; or (3) fall back to the network entity SBFD symbol format, where the UE can operate in half-duplex mode and the network entity operates in SBFD mode. Figure 5 Table 545 illustrates these options. In some cases, the UE can send capability signaling indicating whether the UE supports full-duplex operation and which fallback behavior the UE supports when legacy half-duplex symbols have flexible configuration.
[0112] In another example, if the UE SBFD symbol is configured on a legacy half-duplex flexible symbol, and F / U / F or F / U is configured for network entity SBFD operation on the flexible symbol, the UE SBFD symbol can (1) fall back to the legacy F symbol, where both the network entity and the UE operate in half-duplex mode for that symbol; (2) fall back to the network entity SBFD symbol format (e.g., F / U / F), where the UE can operate in half-duplex mode and the network entity operates in SBFD mode; (3) fall back to the network entity SBFD symbol format D / U / D, where the UE can operate in half-duplex mode and the network entity operates in SBFD mode; (4) update to the legacy U symbol, where both the network entity and the UE operate in half-duplex mode for that symbol; or (5) update to the legacy D symbol, where both the network entity and the UE operate in half-duplex mode for that symbol. Figure 5Table 545 illustrates these options. In some cases, the UE can send capability signaling indicating whether the UE supports full-duplex operation and which fallback behavior the UE supports when the legacy half-duplex symbol has a flexible configuration and the network SBFD configuration is F / U / F or F / U.
[0113] In some respects, dynamic UE SBFD indication can be provided via signaling from network entities. In some cases, dynamic UE SBFD indication can be provided by a scheduling DCI used to schedule downlink reception outside the semi-statically configured SBFD downlink subband and / or uplink transmission outside the semi-statically configured SBFD uplink subband. In some cases, dynamic UE SBFD indication can be provided by a non-scheduled DCI indicating whether a symbol is an SBFD symbol. Such a non-scheduled DCI may include a DCI that does not schedule data or a group common DCI (e.g., a slot format indicator (SFI)). In some cases, dynamic UE SBFD indication can be provided by a MAC-CE indicating whether a symbol is an SBFD symbol.
[0114] In some respects, signaling from network entities can provide an explicit indication of the symbols being updated. This indication can be provided, for example, via a group common DCI (e.g., SFI). In other cases, the indication can be provided via a DCI that does not schedule data (e.g., which may have more bits available for the indication), a DCI that schedules data, or a DCI provided to indicate a full-duplex update, or a newly defined DCI. Such a DCI indication can provide an update for one or more time slots, or it can provide an update that is valid before subsequent updates, which may be referred to as a sticky update. In other cases, additionally or alternatively, the indication can be provided via MAC-CE. In some cases, MAC-CE can provide a sticky update that is valid before a subsequent MAC-CE provides a further update, or it can provide an update to be applied within an indicated time period, after which the SBFD configuration or default or pre-configured format is restored.
[0115] In some respects, signaling from network entities can provide implicit indications of the symbols to be updated. In some cases, the updated symbols can be implied by the scheduled channel or reference signal (e.g., a dynamically scheduled PDSCH with an indication that the scheduled symbols are to be updated). For example, the DCI of the scheduling data can include a one-bit indication of the common mode indication (e.g., back to half-duplex D) regarding the updating of symbols for the scheduled channel or reference signal. In some cases, if a single DCI schedules multiple PDSCH / PUSCH transmissions, such indications may apply only to the scheduled time slot or multiple scheduled time slots.
[0116] In some respects, update indicators can change periodic, semi-persistent, or sticky symbol patterns. In some cases, the indicator can provide a bitmap carrying a detailed bit pattern. For example, such a bitmap can change the original configuration of a semi-static UE SBFD pattern, where the bits in the bitmap correspond to semi-static UE SBFD symbols configured by the network entity, which can reduce overhead (e.g., each bit corresponds to a UE SBFD symbol, where 0 indicates no change and 1 indicates fallback to D). In another example, such a bitmap can redefine the periodic pattern to, for example, add more UE SBFD symbols. In this case, the bits in the bitmap can correspond to all symbols, not just the semi-static UE SBFD symbols configured by the network entity. In some cases, the indicator can provide a predefined periodic pattern ID, where different pattern IDs are mapped to different symbol patterns, as discussed for bitmap indicators.
[0117] In another example, for each cycle, the indication may indicate the offset and length of the updated symbol (e.g., the offset may be relative to the received symbol of the indication, relative to a subset of the updated symbols, or may be an absolute offset). In some aspects, the indication may change one or more timings (e.g., the timing of the update may be aperiodic). For example, the indication may indicate a time window for the updated symbol (e.g., the indication will be applied x ms after the indicated DCI and the last y slots), where a bitmap may be used in the window to indicate the updated symbol (e.g., as discussed above), or where all slots in the window are updated to a specific configuration. Additionally or alternatively, the indication may provide the offset and length of the updated symbol within the window. In some other aspects, the indication may be provided for a single timing location. For example, the indicated DCI may be transmitted on slot n and indicate an offset value of 5 slots / symbols, meaning that on slot / symbol n+5, the UE SBFD falls back to a half-duplex slot / symbol.
[0118] In some respects, the UE full-duplex symbol update application time can be determined based on when the indicated update will be applied to communication between the UE and network entities. In some cases, the application time can be a specified fixed time from the receipt of the indication (e.g., N symbols or K ms from the receipt of the indication in the DCI or MAC-CE). In other cases, the application time can be specified and fixed from the acknowledgment (ACK) of the indication (e.g., N symbols or K ms from the receipt of the acknowledgment to the DCI or MAC-CE). In some cases, for N symbols, the subcarrier spacing (SCS) of the symbols can depend on the SCS of the DCI or MAC-CE, the SCS of the ACK, or the applied downlink / uplink bandwidth portion of the SCS. In further cases, the application time can be indicated by the RRC or the scheduling DCI. In still other cases, the application time can be based on UE capability indications (e.g., filter retuning time indications).
[0119] In some respects, the UE full-duplex symbol initial semi-static indication or dynamic update indication can be applied to one or more CCs. For example, the indicated mode can be applied to one CC, or it can be applied to multiple CCs with a CC list (e.g., each CC has the same UE SBFD configuration). In some cases, the CC list can include all active CCs and deactivated CCs, where the UE only applies the mode to the active CCs, or the CC list can include only active CCs. In other cases, the CCs on the CC list can be explicitly indicated by network entities. Furthermore, network entities can signal the indication via a primary or reference CC, but this indication can be directed to one or more secondary CCs.
[0120] Figure 6 An example of a process flow 600 supporting a technology for full-duplex operation of a UE, according to one or more aspects of this disclosure, is shown. Process flow 600 may include references to... Figures 1 to 5 Various aspects of this disclosure are described. For example, process flow 600 may exemplify techniques for full-duplex communication between UE 115-f and network entity 105-e, which may be references. Figures 1 to 5 Examples of the corresponding devices described. The following alternative examples may be implemented, some of which involve steps performed in a different order than those described, or not performed at all. In some cases, steps may include additional features not mentioned below, or further steps may be added.
[0121] At point 605, UE 115-f can send a capability indication, and network entity 105-e can receive the capability indication, which indicates the capabilities of one or more UE 115-f. For example, the capability indication can provide UE capabilities for performing full-duplex communication, as well as the UE's associated fallback capabilities. Furthermore, the capability indication can provide the UE's timing capabilities, such as the amount of time required to implement a change to the full-duplex configuration at the UE.
[0122] At 610, network entity 105-e can send network full-duplex configuration information, and UE 115-f can receive network full-duplex configuration information. In some cases, the network full-duplex configuration information can update the half-duplex configuration provided by the timeslot format indication to provide a symbol set configured for network full-duplex operation (e.g., for network entity SBFD communication, where the network entity sends downlink communication on one or more downlink subbands while receiving uplink communication on one or more uplink subbands).
[0123] At point 615, network entity 105-e can send UE full-duplex configuration information, and UE 115-f can receive UE full-duplex configuration information. In some cases, the UE full-duplex configuration information can update the network full-duplex configuration to provide a subset of the symbol set configured for UE full-duplex communication (e.g., for UE SBFD communication, where the UE receives downlink communication on one or more downlink subbands while simultaneously sending uplink communication on one or more uplink subbands).
[0124] Optionally, at 620, UE 115-f may send a measurement or interference report, and network entity 105-e may receive the measurement or interference report. The measurement or interference report may, for example, indicate the conditions at UE 115-f, which can be used to determine whether full-duplex communication at the UE can be reliably performed. In some cases, UE 115-f may request one or more symbols or symbol patterns to be configured for half-duplex or full-duplex communication at the UE. At 625, network entity 105-e may determine to update the UE's full-duplex configuration. In some cases, the determination to update the UE's full-duplex configuration may be based on channel conditions associated with the UE (e.g., as measured at the network entity, as reported by the UE, or both), on traffic load (e.g., the amount of downlink or uplink data to be communicated to the UE or with one or more other UEs), on traffic type (e.g., higher priority traffic may benefit from the reduced latency of full-duplex communication), or any combination thereof.
[0125] At 630, network entity 105-e can send a dynamic full-duplex update indication, and UE 115-f can receive the dynamic full-duplex update indication. Such a full-duplex update indication can update one or more UE full-duplex symbols to a half-duplex configuration, depending on various aspects discussed herein. At 635, UE 115-f can determine the UE full-duplex configuration to be updated for one or more symbols based on the full-duplex update indication. Optionally, at 640, based on the updated full-duplex configuration, UE 115-f can send one or more uplink transmissions, and network entity 105-e can receive one or more uplink transmissions. Optionally, at 645, based on the updated full-duplex configuration, network entity 105-e can send one or more downlink transmissions, and UE 115-f can receive one or more downlink transmissions.

[0361] As used herein, the word "or" in a list of items (e.g., a list of items accompanied by phrases such as "at least one of" or "one or more of") in the claims indicates an inclusive list, such that a list of at least one of, for example, A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Furthermore, as used herein, the phrase "based on" should not be construed as a reference to a closed set of conditions. For example, an example step described as "based on condition A" could be based on both condition A and condition B without departing from the scope of this disclosure. In other words, as used herein, the phrase "based on" should be interpreted in the same manner as the phrase "at least partially based on".
[0362] As used herein, including in claims, the article “a” preceding a noun is open-ended and is understood to refer to “at least one” or “one or more” of those nouns. Therefore, the terms “a,” “at least one,” “one or more,” and “at least one of one or more” are interchangeable. For example, where a claim enumerates “components” performing one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Thus, the term “component” having a characteristic or performing a function may refer to “at least one of one or more components” having a particular characteristic or performing a particular function. Subsequent references to a component introduced with the article “a” using the terms “the” or “the” can refer to any or all of the one or more components. For example, a component introduced with the article “a” can be understood to mean “one or more components,” and subsequent reference to “the component” in a claim can be understood as equivalent to referring to “at least one of the one or more components.” Similarly, subsequent references to a component introduced with the terms “the” or “the” as “one or more components” can refer to any or all of the one or more components. For example, reference to "the one or more components" in the subsequent claims can be understood as equivalent to reference to "at least one of the one or more components".
[0363] The term "determine" encompasses a variety of actions, and therefore, "determine" can include calculation, computation, processing, derivation, investigation, lookup (such as by searching in a table, database, or other data structure), identification, and similar actions. Furthermore, "determine" can include receiving (e.g., receiving information), accessing (e.g., accessing data stored in memory), etc. Moreover, "determine" can include parsing, obtaining, selecting, choosing, building, and other similar actions.
[0364] In the accompanying drawings, similar components or features may have the same reference numerals. Furthermore, various components of the same type can be distinguished by adding a dash after the reference numeral and a second reference numeral to differentiate them. If only the first reference numeral is used in the description, the description can be applied to any of the similar components having the same first reference numeral, regardless of the second or other subsequent reference numerals.
[0365] The description herein, illustrated with reference to the accompanying drawings, describes an example configuration and does not represent all achievable examples or those within the scope of the claims. The term "example" as used herein means "serving as an example, instance, or illustration," not "preferred" or "advantageous over other examples." The detailed description includes specific details used to provide an understanding of the described techniques. However, these techniques can be practiced without these specific details. In some instances, known structures and devices are shown in block diagram form to avoid obscuring the concept of the described examples.
