[0002] This patent application claims priority to U.S. Patent Application No. 18 / 447,830, filed August 10, 2023, entitled “WIRELESS COMMUNICATION IN SUBBAND FULL DUPLEX SYMBOLS”, which is assigned to the assignee of this application and is expressly incorporated herein by reference. Technical Field
[0003] The following content pertains to wireless communication, including wireless communication in subband full-duplex (SBFD) symbols. 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). Summary of the Invention
[0005] This disclosure relates to improved methods, systems, apparatuses, and devices for managing one or more symbols for wireless communication, at least in part, based on a Slot Format Indicator (SFI). The SFI may indicate (e.g., allocate, assign, identify) whether a symbol is configured as uplink, downlink, or flexible. For example, a User Equipment (UE) may determine one or more symbols for full-duplex wireless communication, at least in part, based on the SFI, and particularly for Subband Full-Duplex (SBFD) symbols. An SBFD symbol may be referred to as a symbol that simultaneously supports both transmission and reception (e.g., uplink communication, downlink communication) on a subband. This disclosure further relates to the behavior of a UE when receiving an SFI for an SBFD symbol associated with an uplink subband and a flexible subband. In some examples, the UE may expect the SFI to update a flexible symbol to downlink or flexible; update a flexible symbol to downlink, flexible, or uplink; or the UE may not expect to receive the SFI. In some other examples, the SFI may indicate that an SBFD symbol is configured as downlink, and the UE may convert a flexible resource to downlink or convert the entire SBFD symbol to downlink. In other examples, the SFI may designate an SBFD symbol as uplink, and the UE may convert the frequency resources associated with that symbol to uplink. In some other examples, the SFI may designate an SBFD symbol as flexible, and the UE may update the flexible resources in that symbol to flexible or update the frequency resources associated with that symbol to flexible.

[0049] The UE can be configured to support full-duplex operation. For example, the UE can be configured to support full-duplex wireless communication in which the UE can simultaneously receive wireless communication (e.g., downlink communication) and transmit wireless communication (e.g., uplink communication). The UE can also support full-duplex wireless communication over a sub-band (also called a radio frequency spectrum sub-band) that spans a portion of a frequency band (also called a radio frequency spectrum band). The UE can be configured to support full-duplex wireless communication over a sub-band in one or more time and frequency resources (e.g., symbols, time slots, subcarriers). For example, the UE can be configured to allocate and define one or more symbols within a time slot for downlink, uplink, or flexible configuration. The UE can perform uplink communication, downlink communication, or a combination thereof on one or more symbols configured as downlink, uplink, or flexible.
[0050] The UE may receive a configuration including a set of symbols, which may include one or more downlink symbols, one or more flexible symbols, one or more uplink symbols, one or more subband full-duplex (SBFD) symbols, or any combination thereof. An SBFD symbol may be referred to as a symbol that simultaneously supports both transmission and reception (e.g., uplink communication and downlink communication) on a separate subband. The subbands within an SBFD symbol may be downlink subbands, flexible subbands, uplink subbands, guard bands, or any combination thereof. The UE may also support slot format indicators (SFIs), which may be received via downlink control information (DCI) to assign resources within a flexible symbol as downlink resources, uplink resources, or flexible resources. However, for a UE supporting SBFD symbols, there may be uncertainties regarding the SFI assignment for different subbands within an SBFD symbol. For example, the UE may receive a configuration including SBFD symbols comprising one or more uplink subbands, one or more guard bands, and one or more flexible subbands. After receiving an SFI (Symbol Filtering Function) assigned to a symbol for downlink, the UE may not know whether to convert resources in a subband (e.g., including one or more uplink subbands) to downlink or only convert flexible subbands within the SBFD symbol to downlink.
[0051] This disclosure relates to improved methods, systems, apparatuses, and devices that enable a UE to manage one or more symbols for wireless communication based at least in part on a Single Component Information (SFI) received via a DCI (e.g., DCI format 2_0). The SFI may indicate (e.g., allocate, assign, identify) whether a symbol is configured as uplink, downlink, or flexible. Specifically, the UE may determine one or more symbols for full-duplex wireless communication based at least in part on the SFI, and particularly for SBFD symbols. This disclosure further relates to the behavior of the UE when receiving an SFI for SBFD symbols associated with uplink subbands and flexible subbands. In some examples, the UE may expect the SFI to update a flexible symbol to downlink or flexible; the UE may expect the SFI to update a flexible symbol to downlink, flexible, or uplink; or the UE may not expect to receive the SFI. In some other examples, the SFI may indicate that an SBFD symbol is configured as downlink, and the UE may convert flexible resources (e.g., excluding one or more uplink subbands) to downlink or convert the entire SBFD symbol to downlink. In other examples, the SFI may designate an SBFD symbol as uplink, and the UE may convert the frequency resources associated with that symbol (e.g., including one or more uplink subbands) to uplink. In some other examples, the SFI may designate an SBFD symbol as flexible, and the UE may update the flexible resources in that symbol to flexible or update the frequency resources associated with that symbol to flexible (e.g., the UE may update the uplink subband associated with that symbol to flexible).
[0052] First, aspects of this disclosure are described in the context of a wireless communication system. Then, aspects of this disclosure are described in the context of resource diagrams and process flows. Aspects of this disclosure are further illustrated and described with reference to apparatus diagrams, system diagrams, and flowcharts related to wireless communication in SBFD symbols.
[0053] Figure 1 An example of a wireless communication system 100 supporting wireless communication in an SBFD symbol 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 an LTE network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, an NR network, or a network operating according to other systems and radio technologies, including future systems and radio technologies not expressly mentioned herein.
[0054] 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).
[0055] 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 1 Some example UE 115s are illustrated herein. The UE 115 described herein can be able to support various types of devices (such as, e.g., ...). Figure 1 It communicates with other UEs (115 or network entity 105) as shown.
[0056] 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.
[0057] In some examples, network entity 105 may communicate with core network 130, 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.
[0058] 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).
[0059] 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)).
[0060] 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.
[0061] 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.
[0062] When the techniques described herein are applied in the context of a decomposed RAN architecture, one or more components of the decomposed RAN architecture may be configured to support wireless communication in SBFD symbols as described herein. 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).
[0063] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or any 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.
[0064] The UE 115 described herein can communicate with various types of devices, such as other UEs 115 that sometimes act as relays, 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.
[0065] 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 can support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 may be configured with 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, CU160, DU 165, RU 170) communicating with another device (e.g., directly or via one or more other network entities 105).
[0066] 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 made 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.
[0067] 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).
[0068] 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.
[0069] 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 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.
[0070] 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).
[0071] 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.
[0072] 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)).
[0073] 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.
[0074] 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.
[0075] 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.
[0076] 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.
[0077] In some systems, the D2D communication link 135 may be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, vehicles may communicate using vehicle-to-vehicle (V2X) communication, vehicle-to-vehicle (V2V) communication, or a combination of these. Vehicles may signal information related to traffic conditions, signal control, weather, safety, emergencies, or any other information relevant to the V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure (such as roadside units), or communicate with the network via one or more network nodes (e.g., network entity 105, base station 140, RU 170) using vehicle-to-network (V2N) communication, or both.
[0078] 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.
[0079] 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 wavelengths in the lower 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).
[0080] 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.
[0081] 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.
[0082] Network entity 105 or UE 115 can use MIMO communication to leverage multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. This technique is known as spatial multiplexing. The multiple signals can be transmitted, for example, by a transmitting device via different antennas or different combinations of antennas. Similarly, the multiple signals can be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include: single-user MIMO (SU-MIMO), where multiple spatial layers are transmitted to the same receiving device; and multi-user MIMO (MU-MIMO), where multiple spatial layers are transmitted to multiple devices.
[0083] 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 orientation (e.g., relative to the antenna array of the transmitting or receiving device or relative to some other orientation).
[0084] Network entity 105 or UE 115 may use beam scanning technology as part of beamforming operations. For example, network entity 105 (e.g., base station 140, RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by network entity 105 along different directions. For example, network entity 105 may transmit signals according to different beamforming weight sets associated with different transmission directions. Transmission along different beam directions may be used to identify (e.g., by a transmitting device (such as network entity 105) or by a receiving device (such as UE 115)) the beam direction for later transmission or reception by network entity 105.
[0085] Some signals (such as data signals associated with a specific receiving device) may be transmitted by a transmitting device (e.g., transmitting network entity 105, transmitting UE 115) along a single beam direction (e.g., the direction associated with the receiving device (such as receiving network entity 105 or receiving UE 115). In some examples, the beam direction associated with transmission along a single beam direction may be determined based on the signals transmitted along one or more beam directions. For example, UE 115 may receive one or more signals transmitted by network entity 105 along different directions and may report to network entity 105 an indication of signals received by UE 115 with the highest signal quality or other acceptable signal quality.
[0086] In some examples, transmissions performed by a device (e.g., network entity 105 or UE 115) may be performed using multiple beam directions, and the device may use a combination of digital pre-decoding or beamforming to generate a combined beam for transmission (e.g., from network entity 105 to UE 115). UE 115 may report feedback indicating pre-decoding weights for one or more beam directions, and this feedback may correspond to a set of beams configured across the system bandwidth or one or more sub-bands. Network entity 105 may transmit reference signals (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)) that may or may not be pre-decoded. UE 115 may provide feedback for beam selection, which may be a pre-decoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel codebook, linear combination codebook, port selection codebook). Although these techniques are described with reference to signals transmitted by network entity 105 (e.g., base station 140, RU 170) along one or more directions, UE 115 may use similar techniques to transmit signals multiple times along different directions (e.g., to identify the beam direction used by UE 115 for subsequent transmission or reception), or to transmit signals along a single direction (e.g., to transmit data to a receiving device).
[0087] A receiving device (e.g., UE 115) may perform reception operations according to multiple reception configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from a transmitting device (e.g., network entity 105). For example, the receiving device may perform reception according to multiple reception directions by: receiving via different antenna subarrays; processing the received signal according to different antenna subarrays; receiving according to different sets of reception beamforming weights (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of the antenna array; or processing the received signal according to different sets of reception beamforming weights applied to signals received at multiple antenna elements of the antenna array. Any of these operations may be referred to as “listening” according to different reception configurations or reception directions. In some examples, the receiving device may use a single reception configuration to receive along a single beam direction (e.g., when a data signal is received). A single receiver configuration can be aligned along a beam direction determined based on listening according to different receiver configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or other acceptable signal quality based on listening according to multiple beam directions).
[0088] 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 use error detection, error correction, or both to support retransmissions to 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.
[0089] 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 can 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.
[0090] For SBFD operation configured as a flexible symbol in TDD-UL-DL-ConfigCommon, the SBFD-aware UE may have at least two options. In one option, uplink transmission may be allowed within the uplink subband of the SBFD symbol, and uplink transmission may not be allowed outside the uplink subband of the SBFD symbol. Downlink reception may be allowed within the downlink subband of the SBFD symbol, and downlink reception may be allowed outside the downlink subband of the SBFD symbol. In a second option, uplink transmission may be allowed within the uplink subband of the SBFD symbol, while resource blocks outside the uplink subband may be used as uplink or downlink (excluding any guard band). The transmission direction (e.g., uplink or downlink) for resource blocks within the SBFD symbol can be the same. For example, if the SBFD symbol is indicated as uplink, the flexible subband within the SBFD symbol may be converted to uplink. Downlink reception may be allowed within the downlink subband of the SBFD symbol, and the SBFD symbol may be converted to a downlink-only symbol. For both options, uplink transmission can be within the active uplink bandwidth portion (BWP), and downlink reception can be within the active downlink BWP in the SBFD symbol. For resource blocks outside the uplink subband, the UE may not allocate a single resource block for both downlink and uplink simultaneously.
[0091] In some examples, an SBFD-aware UE may receive a DCI (e.g., DCI format 2_0) including an SFI to update one or more flexible slots or symbols for downlink, uplink, or flexible. In some examples, the SFI may point to an entry in a table that includes a specific configuration of uplink resources, downlink resources, and flexible resources (e.g., slotFormatCombinationId=3). The UE can then manage the resources accordingly.
[0092] Semi-flexible symbols can be pointed to by tdd-UL-DL-ConfigurationCommon or tdd-ULDL- ConfigurationDedicated The symbol is indicated as flexible. In some examples, an SBFD-aware UE that supports receiving SFIs via DCI format 2_0 may experience ambiguity regarding UE behavior in response to an SFI that updates a subset of flexible symbols. For example, an SBFD-aware UE may be unsure how to respond to an SFI indicating a semi-flexible symbol, on which the uplink subband is configured as a downlink symbol, an uplink symbol, or an SFI flexible symbol.
[0093] Wireless communication system 100 may support the management of one or more symbols used for wireless communication based at least in part on a Single Component Information (SFI) received from network entity 105. The SFI may indicate (e.g., allocate, assign, identify) whether a symbol is configured as uplink, downlink, or flexible. For example, UE 115 may determine one or more symbols used for full-duplex wireless communication based at least in part on the SFI, and particularly for SBFD symbols. This disclosure further relates to the behavior of UE 115 when receiving an SFI for SBFD symbols associated with uplink and flexible subbands. In some examples, UE 115 may expect the SFI to update a flexible symbol to downlink or flexible; update a flexible symbol to downlink, flexible, or uplink; or UE 115 may not expect to receive an SFI from network entity 105. In some other examples, the SFI may indicate that an SBFD symbol is configured as downlink, and UE 115 may convert a flexible resource to downlink or convert an entire SBFD symbol to downlink. In other examples, the SFI may designate an SBFD symbol as uplink, and the UE 115 may convert the frequency resources associated with that symbol to uplink. In some other examples, the SFI may designate an SBFD symbol as flexible, and the UE 115 may update the flexible resources in that symbol (e.g., excluding one or more uplink subbands) to flexible, or update the frequency resources associated with that symbol (e.g., including one or more uplink subbands) to flexible.
[0094] Figure 2 An example of a wireless communication system 200 supporting wireless communication in SBFD symbols according to one or more aspects of this disclosure is shown. Wireless communication system 200 may implement, or be implemented by, wireless communication system 100. For example, wireless communication system 200 may include network entity 105-a and UE 115-a, which may represent references... Figure 1 Examples of network entity 105 and UE 115 described.
[0095] In the wireless communication system 200, network entity 105-a can support full-duplex operation, in which network entity 105-a can simultaneously transmit downlink communication to UE 115-a and receive uplink communication from UE 115-a. Alternatively or additionally, UE 115-a can support full-duplex operation, in which UE 115-a can simultaneously transmit uplink communication to network entity 105-a and receive downlink communication from network entity 105-a.
[0096] exist Figure 2In the example, network entity 105-a and UE 115-a may support full-duplex operation on one or more SBFD symbols. For example, network entity 105-a may send a first control signaling 205 to UE 115-a. The first control signaling 205 may indicate a first configuration including a set of symbols (e.g., SBFD symbols) associated with SBFD operation. The SBFD symbol set may include a first subset of downlink symbols, a second subset of flexible symbols, a third subset of uplink symbols, or a combination thereof. In some examples, the second subset of flexible symbols may be associated with an uplink subband. That is, based on the first configuration indicated in the first control signaling 205, a subset of frequency resources within one or more flexible SBFD symbols may be configured for uplink transmission.
[0097] Network entity 105-a may send a second control signaling 210 to UE 115-a indicating a second configuration. The second configuration may be associated with monitoring the Physical Downlink Control Channel (PDCCH). That is, UE 115-a may be configured to monitor the PDCCH (e.g., to obtain a DCI) based on the second configuration indicated in the second control signaling 210. Network entity 105-a may send a DCI 215 (e.g., DCI format 2_0) including an SFI to UE 115-a. The SFI may indicate one or more flexible symbols in a second subset of flexible symbols as uplink, downlink, or a combination thereof.
[0098] For example, UE 115-a may expect the SFI to update the flexible symbol to downlink or flexible; update the flexible symbol to downlink, flexible, or uplink; or UE 115 may not expect to receive the SFI from network entity 105-a, as referenced. Figure 3 A more detailed description follows. In some other examples, the SFI may indicate that the SBFD symbol is configured as downlink, and the UE 115-a may convert flexible resources to downlink or convert the entire SBFD symbol to downlink, as referenced in [reference missing]. Figure 4 A more detailed description follows. In other examples, the SFI can designate an SBFD symbol as uplink, and the UE 115-a can convert the frequency resources associated with that symbol to uplink, as referenced in [reference missing]. Figure 5 A more detailed description follows. In some other examples, the SFI may indicate an SBFD symbol as flexible, and UE 115-a may update the flexible resources in that symbol to flexible or update the frequency resources associated with that symbol (e.g., including one or more uplink subbands) to flexible, as referenced. Figure 6 To describe in more detail.
[0099] Network entity 105-a and UE 115-a may perform wireless communication 220 based on first control signaling 205, second control signaling 210, DCI 215 or a combination thereof.
[0100] Figure 3 An example of resource diagram 300 supporting wireless communication in SBFD symbols according to one or more aspects of this disclosure is shown. Resource diagram 300 can be implemented with reference to, respectively Figure 1 and Figure 2 The described wireless communication system 100 and wireless communication system 200 may refer to one or more aspects, or be implemented therein. For example, resource diagram 300 may be derived from reference to... Figure 1 and Figure 2 The network entity 105 and UE 115 described are implemented to support full-duplex wireless communication.
[0101] UE 115 may receive a first control signaling indicating a first configuration including a set of SBFD symbols (such as SBFD symbol set 305-a). In some examples, SBFD symbol set 305-a may include one or more downlink resources 315 (e.g., downlink symbols or downlink subbands), one or more flexible resources 320 (e.g., flexible symbols 310-a or flexible subbands), and one or more uplink resources 325 (e.g., uplink symbols or uplink subbands). Flexible symbols 310-a may include one or more uplink resources 325 (e.g., uplink subbands) and one or more flexible resources (e.g., flexible subbands) associated with one or more guard bands 330. UE 115 may receive a second control signaling indicating a second configuration associated with a monitoring PDCCH. UE 115 may receive a DCI (e.g., DCI format 2_0) based on the monitoring PDCCH, where the DCI includes an SFI. The SFI may indicate flexible symbols 310-a in SBFD symbol set 305-a as uplink or downlink or a combination thereof. Figure 3 In the example, resource diagram 300 depicts three exemplary UE responses to receiving SFI.
[0102] In some examples, UE 115 may receive an SFI indicating a flexible symbol 310-a in SBFD symbol set 305-a as a downlink or flexible symbol. That is, UE 115 may not expect to receive an SFI indicating a flexible symbol 310-a as an uplink symbol. SBFD symbol set 305-b depicts the SBFD symbols after UE 115 receives an SFI indicating a flexible symbol 310-b as a downlink symbol, and includes the uplink subband and guard band unchanged compared to SBFD symbol set 305-a, and two downlink subbands instead of flexible subbands. UE 115 may perform wireless communication with network entity 105 based on SBFD symbol set 305-b. (See reference...) Figure 4 In more detail, UE 115 may determine (e.g., read, decode, interpret) the SFI to indicate the entire flexible symbol 310-b as a downlink, or only the flexible resource 320 within the flexible symbol 310-b as a downlink.
[0103] In some examples, UE 115 may not receive DCI including SFIs for SBFD symbols and slots. In such examples, UE 115 may not expect to receive SFIs in SBFD symbols or SBFD slots. Therefore, UE 115 may suppress updates to the SBFD symbol set 305-c, thereby keeping the flexible resource 320 associated with the flexible symbol 310-c flexible. UE 115 may perform wireless communications with network entity 105 based on the SBFD symbol set 305-c.
[0104] In some examples, UE 115 may receive an SFI indicating a flexible symbol 310-a in SBFD symbol set 305-a as downlink, flexible, uplink, or any combination thereof. SBFD symbol set 305-d depicts SBFD symbols after UE 115 receives an SFI indicating a flexible symbol 310-b as uplink, and wherein flexible symbol 310-d does not include guard band 330, downlink resource 315, or flexible resource 320. UE 115 may perform wireless communications with network entity 105 based on SBFD symbol set 305-d.
[0105] Figure 4 An example of resource diagram 400 supporting wireless communication in SBFD symbols according to one or more aspects of this disclosure is shown. Resource diagram 400 can be implemented with reference to, respectively Figure 1 and Figure 2 The described wireless communication system 100 and wireless communication system 200 may refer to one or more aspects, or be implemented therein. For example, resource diagram 400 may be derived from reference to... Figure 1 and Figure 2The described network entity 105 and UE 115 are implemented to support full-duplex wireless communication. Resource Figure 400 shows SBFD symbol sets 405-a, 405-b, and 405-c, which can be used as references. Figure 3 Examples of the described SBFD symbol sets 305-a and 305-b.
[0106] UE 115 may receive a first control signaling indicating a first configuration including a set of SBFD symbols (such as SBFD symbol set 405-a). In one example, the initial SBFD symbol set 405-a may include one or more downlink resources 415 (e.g., downlink symbols or downlink subbands), one or more flexible resources 420 (e.g., flexible symbols 410-a or flexible subbands), and one or more uplink resources 425 (e.g., uplink symbols or uplink subbands). Flexible symbols 410-a may include one or more uplink resources 425 (e.g., uplink subbands) surrounded by one or more guard bands 430, and one or more flexible resources 420 (e.g., flexible subbands). UE 115 may receive a second control signaling indicating a second configuration associated with the monitored PDCCH. UE 115 may receive DCI based on the monitored PDCCH, where the DCI includes SFI. For example, the DCI may include DCI format 2_0 with slot format values other than a specific value (e.g., 255). The SFI can indicate the flexible symbol 410-a associated with the SBFD symbol set 405-a as an uplink, a downlink, or a combination thereof. Resource Figure 400 depicts two exemplary UE responses (e.g., interpretation) to receiving an SFI that indicates the flexible symbol 410-a as a downlink.
[0107] In some examples, UE 115 may interpret (e.g., read, decode) an SFI to indicate flexible symbol 410-a in SBFD symbol set 405-a as downlink, so that it applies only to flexible resource 420 (e.g., flexible subband) within flexible symbol 410-a. For example, SBFD symbol set 405-b depicts SBFD symbols after UE 115 receives an SFI with this interpretation indicating flexible symbol 410-b as downlink. Note that SBFD symbol set 405-b includes uplink resource 425 and guard band 430 unchanged from SBFD symbol set 405-a, and downlink resource 415 replacing flexible resource 420. UE 115 may perform wireless communication with network entity 105 based on SBFD symbol set 405-b.
[0108] In some examples, UE 115 may interpret (e.g., read, decode) the SFI to indicate the flexible symbol 410-a in the SBFD symbol set 405-a as downlink and apply it to frequency resources within the flexible symbol 410-a, including the uplink subband and guard band 430. That is, the SFI may cover the uplink resource 425 within the flexible symbol 410-a. For example, the SBFD symbol set 405-c depicts the SBFD symbol after UE 115 receives the interpreted SFI indicating the flexible symbol 410-c as downlink. This signaling switches the SBFD symbol to a non-SBFD symbol (e.g., in this example, to a downlink symbol). Note that the SBFD symbol set 405-c only includes the downlink resource 415 and does not include the uplink resource 425 or guard band 430 from the SBFD symbol set 405-a. UE 115 may perform wireless communication with network entity 105 based on the SBFD symbol set 405-c.
[0109] Figure 5 An example of resource diagram 500 supporting wireless communication in SBFD symbols according to one or more aspects of this disclosure is shown. Resource diagram 500 can be implemented with reference to, respectively Figure 1 and Figure 2 The described wireless communication system 100 and wireless communication system 200 may refer to one or more aspects, or be implemented therein. For example, resource diagram 500 may be derived from reference to... Figure 1 and Figure 2 The described network entity 105 and UE 115 are implemented to support full-duplex wireless communication. Resource Figure 500 shows SBFD symbol sets 505-a and 505-b, which can be respectively as referenced. Figure 3 Examples of the described SBFD symbol sets 305-a and 305-d.
[0110] UE 115 may receive a first control signaling indicating a first configuration including a set of SBFD symbols (such as SBFD symbol set 505-a). In one example, SBFD symbol set 505-a may include one or more downlink resources 515 (e.g., downlink symbols or downlink subbands), one or more flexible resources 520 (e.g., flexible symbols 510-a or flexible subbands), and one or more uplink resources 525 (e.g., uplink symbols or uplink subbands). Flexible symbols 510-a may include one or more uplink resources 525 (e.g., uplink subbands) surrounded by one or more guard bands 530, and one or more flexible resources 420 (e.g., flexible subbands). UE 115 may receive a second control signaling indicating a second configuration associated with the monitored PDCCH. UE 115 may receive DCI based on the monitored PDCCH, where the DCI includes SFI. For example, the DCI may include DCI format 2_0 with slot format values other than a specific value (e.g., 255). The SFI can indicate the flexible symbol 510-a in the SBFD symbol set 505-a as an uplink or downlink or a combination thereof. Resource Figure 500 depicts an exemplary UE response (e.g., interpretation) to receiving an SFI that indicates the flexible symbol 510-a as an uplink.
[0111] In some examples, UE 115 may interpret the SFI indicating flexible symbol 510-a in SBFD symbol set 505-a as uplink for application to frequency resources within flexible symbol 510-a, including guard band 530. For example, SBFD symbol set 505-b depicts SBFD symbols after UE 115 receives an SFI indicating flexible symbol 510-b as uplink with this interpretation. Note that SBFD symbol set 505-b includes only uplink resource 525 and does not include guard band 530 from SBFD symbol set 505-a. UE 115 may cancel downlink transmissions of any RRC configuration in flexible symbol 510-b. UE 115 may perform wireless communication with network entity 105 based on SBFD symbol set 505-b.
[0112] Figure 6 An example of resource diagram 600 supporting wireless communication in SBFD symbols according to one or more aspects of this disclosure is shown. Resource diagram 600 can be implemented with reference to, respectively Figure 1 and Figure 2 The described wireless communication system 100 and wireless communication system 200 may refer to one or more aspects, or be implemented therein. For example, resource diagram 600 may be derived from reference to... Figure 1 and Figure 2The described network entity 105 and UE 115 are implemented to support full-duplex wireless communication. Resource Figure 600 shows SBFD symbol set 605-a, which can be a reference. Figure 3 An example of the SBFD symbol set 305-a described.
[0113] UE 115 may receive a first control signaling indicating a first configuration including a set of SBFD symbols (such as SBFD symbol set 605-a). In one example, the initial SBFD symbol set 605-a may include one or more downlink resources 615 (e.g., downlink symbols or downlink subbands), one or more flexible resources 620 (e.g., flexible symbols 610-a or flexible subbands), and one or more uplink resources 625 (e.g., uplink symbols or uplink subbands). Flexible symbols 610-a may include one or more uplink resources 625 (e.g., uplink subbands) surrounded by one or more guard bands 630, and one or more flexible resources 620 (e.g., flexible subbands). UE 115 may receive a second control signaling indicating a second configuration associated with the monitored PDCCH. UE 115 may receive DCI based on the monitored PDCCH, where the DCI includes SFI. For example, the DCI may include DCI format 2_0 with slot format values other than a specific value (e.g., 255). The SFI can indicate the flexible symbol 610-a in the SBFD symbol set 605-a as uplink, downlink, or a combination thereof. Resource Figure 600 depicts two exemplary UE responses (e.g., interpretation) to receiving a flexible symbol 610-a indicating a flexible SFI. In such examples, UE 115 discards or cancels transmissions and receptions configured at higher layers (e.g., CSI-RS, Sounding Reference Signal (SRS), Physical Uplink Control Channel (PUCCH), Physical Uplink Shared Channel (PUSCH), or any combination thereof).
[0114] In some examples, UE 115 may interpret a flexible symbol 610-a in SBFD symbol set 605-a as a flexible SFI, so that it applies only to the flexible resource 620 (e.g., flexible subband) within flexible symbol 610-a. For example, SBFD symbol set 605-b depicts SBFD symbols after UE 115 receives an SBFD symbol that indicates flexible symbol 610-b as a flexible SFI with that interpretation. Note that SBFD symbol set 605-b includes uplink resource 625 and guard band 630 unchanged from SBFD symbol set 605-a, as well as flexible resource 620. UE 115 may perform wireless communications with network entity 105 based on SBFD symbol set 605-b.
[0115] In some examples, UE 115 can interpret a flexible symbol 610-a in SBFD symbol set 605-a as a flexible SFI to be applied to frequency resources within flexible symbol 610-a, including uplink subband and guard band 630. That is, the SFI can cover uplink resource 625 within flexible symbol 610-a. For example, SBFD symbol set 605-c depicts an SBFD symbol after UE 115 receives a flexible symbol 610-c with this interpreted SFI. Note that SBFD symbol set 605-c only includes flexible resource 620 and does not include uplink resource 625 or guard band 630 from SBFD symbol set 605-a. That is, flexible symbol 610-a becomes SFI flexible symbol 610-c. UE 115 can perform wireless communication with network entity 105 based on SBFD symbol set 605-c.
[0116] Figure 7 An example of a process flow 700 supporting wireless communication in an SBFD symbol according to one or more aspects of this disclosure is shown. In some examples, process flow 700 may implement, or be implemented by, aspects of, wireless communication system 100, wireless communication system 200, resource map 300, resource map 400, resource map 500, resource map 600, or any combination thereof. For example, process flow 700 may include UE 115-b and network entity 105-b, which may be as described herein with respect to Figure 1 Examples of the corresponding devices described. After process flow 700, network entity 105-b may configure UE 115-b to perform wireless communication via an SBFD flexible symbol indicated as downlink, flexible, uplink, or any combination thereof. The following alternative examples may be implemented, some of which may be performed in a different order than described or not at all. In some cases, steps may include additional features not mentioned below, or additional steps may be added. Although UE 115-b and network entity 105-b are shown performing the operations of process flow 700, some aspects of some operations may also be performed by one or more other wireless devices.
[0117] At 705, network entity 105-b may send a first control signaling indicating a first configuration to UE 115-b. The first configuration may include a set of symbols (e.g., SBFD symbols) associated with SBFD operation. The SBFD symbol set may include one or more of the following: a first subset of downlink symbols, a second subset of flexible symbols, a third subset of uplink symbols, or a combination thereof. The second subset of flexible symbols may be associated with uplink subbands. That is, the second subset of flexible symbols may include at least one flexible symbol that includes at least one uplink subband. A flexible symbol including at least one uplink subband may also include one or more flexible subbands and one or more guard bands separating the frequency resources of the at least one uplink subband from the frequency resources of the one or more flexible subbands. In some examples, the first control signaling may be an RRC message, such that the first configuration is included in the RRC message. In some examples, the control signaling may be another type of control signaling.
[0118] At 710, network entity 105-b may send a second control signaling to UE 115-b indicating a second configuration associated with monitoring the PDCCH. For example, the second configuration may configure UE 115-b to monitor the DCI.
[0119] At 715, network entity 105-b may send DCI to UE 115-b based on DCI monitored by UE 115-b. The DCI may include an SFI that indicates one or more flexible symbols in a second subset of flexible symbols as uplink or downlink or a combination thereof. In some examples, the DCI may include a DCI format (e.g., DCI format 2_0).
[0120] UE 115-b can determine that the SFI indicates one or more flexible symbols in a second subset of flexible symbols as downlink, flexible, or uplink, and can accordingly switch one or more flexible symbols at 720. For example, UE 115-b can determine, based on the SFI, that one or more flexible symbols in a second subset of flexible symbols are indicated as downlink or flexible. Wireless communication at 725 can be performed based on this determination. For example, UE 115-b can receive downlink communication at 725 in one or more flexible symbols in a second subset of flexible symbols that UE 115-b has determined, based on the SFI, to be indicated as downlink. In some examples, UE 115-b can determine whether the DCI includes the SFI, and can perform wireless communication at 725 based on this determination. In some examples, UE 115-b can determine that the SFI indicates one or more flexible symbols in a second subset of flexible symbols as flexible, uplink, downlink, or a combination thereof, and can perform wireless communication at 725 based on this determination.
[0121] In some examples, UE 115-b may determine that the SFI includes slot format values other than a specific value (e.g., 255), and may perform wireless communication at 725 based on this determination. For example, UE 115-b may determine that the SFI indicates one or more flexible symbols in a second subset of flexible symbols as downlink based on the SFI including slot format values other than the specific value, and may perform wireless communication at 725 based on this determination (e.g., UE 115-b may receive downlink communication in one or more flexible symbols in the second subset of flexible symbols that UE 115-b has determined to be indicated as downlink based on the SFI). UE 115-b may interpret the SFI in one of several ways. In a first interpretation, UE 115-b may determine that the SFI updates one or more frequency resources associated with one or more flexible symbols in the second subset of flexible symbols to downlink and may maintain the uplink subband and one or more guard bands associated with the one or more flexible symbols. In the second example, UE 115-b can determine that SFI will update one or more frequency resources, including uplink subbands and one or more guard bands, associated with one or more flexible symbols in a second subset of flexible symbols to downlink.
[0122] In some examples, UE 115-b can determine, based on a slot format value in the SFI (Indicating Slots) that the SFI indicates one or more flexible symbols in a second subset of flexible symbols as uplinks. Wireless communication at 725 can be performed based on this determination. For example, UE 115-b can transmit one or more uplink communications in one or more flexible symbols indicated as uplinks by the SFI.
[0123] In some examples, UE 115-b may determine that the SFI indicates one or more flexible symbols in a second subset of flexible symbols to be flexible based on a slot format value that includes, but is not limited to, a specific value. Wireless communication at 725 may be performed based on this determination. UE 115-b may interpret the SFI in one of several ways. In a first interpretation, UE 115-b may determine that the SFI updates one or more frequency resources associated with one or more flexible symbols in the second subset of flexible symbols to be flexible and may maintain the uplink subband and one or more guard bands associated with the one or more flexible symbols. In a second interpretation, UE 115-b may determine that the SFI updates the frequency resources associated with one or more flexible symbols in the second subset of flexible symbols to be flexible, including the uplink subband and one or more guard bands associated with the one or more flexible symbols.
[0124] At 725, UE 115-b and network entity 105-b may perform wireless communication based on a first configuration, a second configuration, DCI, or any combination thereof. For example, UE 115-b and network entity 105-b may perform wireless communication based on any determination made by UE 115-b as discussed at 720.
[0125] Figure 8 A block diagram 800 of a device 805 supporting wireless communication in an SBFD symbol according to one or more aspects of this disclosure is shown. Device 805 may be an example of various aspects of UE 115 as described herein. Device 805 may include a receiver 810, a transmitter 815, and a communication manager 820. Device 805, or one or more components of device 805 (e.g., receiver 810, transmitter 815, and communication manager 820), may include at least one processor that may be coupled to at least one memory to individually or jointly support or implement the described techniques. Each of these components may communicate with each other (e.g., via one or more buses).
[0126] Receiver 810 may provide components for receiving information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels related to wireless communication in SBFD symbols). The information may be passed to other components of device 805. Receiver 810 may utilize a single antenna or a collection of antennas.
[0127] Transmitter 815 may provide components for transmitting signals generated by other components of device 805. For example, transmitter 815 may transmit information associated with various information channels (e.g., control channels, data channels, information channels related to wireless communication in SBFD symbols), such as packets, user data, control information, or any combination thereof. In some examples, transmitter 815 may be co-located with receiver 810 in a transceiver module. Transmitter 815 may utilize a single antenna or a collection of multiple antennas.
[0128] The communication manager 820, receiver 810, transmitter 815, or various combinations thereof, or various components thereof, may be examples of parts for performing various aspects of wireless communication as described herein in the SBFD symbols. For example, the communication manager 820, receiver 810, transmitter 815, or various combinations thereof, or components thereof, may be able to perform one or more of the functions described herein.
[0129] In some examples, the communication manager 820, receiver 810, transmitter 815, or various combinations or components thereof may be implemented in hardware (e.g., in communication management circuitry). The hardware may include at least one of the following: a processor, digital signal processor (DSP), central processing unit (CPU), application-specific integrated circuit (ASIC), field-programmable gate array (FPGA) or other programmable logic device, microcontroller, discrete gate or transistor logic component, discrete hardware component, or any combination thereof, configured as or otherwise individually or collectively to support components for performing the functions described herein. In some examples, at least one processor and at least one memory coupled to said at least one processor may be configured to perform one or more of the functions described herein (e.g., instructions stored in at least one memory are executed individually or collectively by one or more processors).
[0130] Additionally or alternatively, the communication manager 820, receiver 810, transmitter 815, or various combinations or components thereof may be implemented in code (e.g., as communication management software or firmware) executed by at least one processor. If implemented in code executed by at least one processor, the functionality of the communication manager 820, receiver 810, transmitter 815, or various combinations or components thereof may be performed by (e.g., a general-purpose processor, DSP, CPU, ASIC, FPGA, microcontroller, or any combination of these or other programmable logic devices configured, either individually or collectively, as a component for performing the functions described in this disclosure).
[0131] In some examples, the communication manager 820 may be configured to use or otherwise cooperate with the receiver 810, transmitter 815, or both to perform various operations (e.g., receiving, acquiring, monitoring, outputting, transmitting). For example, the communication manager 820 may receive information from the receiver 810, transmit information to the transmitter 815, or be integrated with the receiver 810, transmitter 815, or both to acquire information, output information, or perform various other operations as described herein.
[0132] Communication manager 820 may support wireless communication according to examples disclosed herein. For example, communication manager 820 may be capable of, configured to, or operable to support components for receiving first control signaling indicating a first configuration including a set of symbols associated with SBFD operation, wherein the set of symbols includes one or more of the following: a first subset of downlink symbols, a second subset of flexible symbols, a third subset of uplink symbols, or a combination thereof, and wherein the second subset of flexible symbols is associated with an uplink subband.

For example, data, instructions, commands, information, signals, bits, symbols, and chips mentioned throughout the description can be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, light fields or optical particles, or any combination thereof.
[0250] The various exemplary blocks and components described herein can be implemented or performed using a general-purpose processor, DSP, ASIC, CPU, FPGA or other programmable logic device, discrete gate or transistor logic unit, discrete hardware component, or any combination thereof, designed to perform the functions described herein. A general-purpose processor may be a microprocessor, but in alternative embodiments, a processor may be any processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors combined with a DSP core, or any other such configuration). Any function or operation described herein that can be performed by a processor may be performed by multiple processors capable of performing the described functions or operations individually or jointly.
[0251] The functions described herein can be implemented using hardware, software executed by a processor, firmware, or any combination thereof. When implemented using software executed by a processor, the functions can be stored as one or more instructions or code on a computer-readable medium or transmitted using one or more instructions or code on a computer-readable medium. Other examples and specific implementations are within the scope of this disclosure and the appended claims. For example, due to the nature of software, the functions described herein can be implemented using software executed by a processor, hardware, firmware, hardwiring, or any combination of these. Features implementing the functions can also be physically located in various locations, including various portions distributed such that the functions are implemented in different physical locations.
[0252] Computer-readable media includes both non-transitory computer storage media and communication media, encompassing any medium that facilitates the transfer of a computer program from one location to another. Non-transitory storage media can be any available medium accessible by a general-purpose or special-purpose computer. By way of example, and not limitation, non-transitory computer-readable media may include RAM, ROM, electrically erasable programmable ROM (EEPROM), flash memory, compressed optical disc (CD) ROM or other optical disc storage devices, magnetic disk storage devices or other magnetic storage devices, or any other non-transitory medium that can be used to carry or store desired program code components in the form of instructions or data structures, and accessible by a general-purpose or special-purpose computer or a general-purpose or special-purpose processor. Furthermore, any connection is appropriately referred to as computer-readable media. For example, if software is transmitted from a website, server, or other remote source using coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwave, then coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included within the definition of computer-readable media. As used herein, disks and optical discs include CDs, laser discs, optical discs, digital multifunction discs (DVDs), floppy disks, and Blu-ray discs. Disks can magnetically reproduce data, and optical discs can optically reproduce data using lasers. Combinations of the above are also included within the scope of computer-readable media. Any function or operation described herein that can be performed by memory can be performed by multiple memories capable of performing the described function or operation individually or jointly.
[0253] 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".
[0254] 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".
[0255] 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, acquiring, selecting, choosing, creating, and other similar actions.
[0256] 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 between similar components. 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 reference numeral or other subsequent reference numerals.
[0257] 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 cases, known structures and devices are shown in block diagram form to avoid obscuring the concept of the described examples.
[0258] The description herein is provided to enable those skilled in the art to implement or use this disclosure. Various modifications to this disclosure will be apparent to those skilled in the art, and the general principles defined herein may be applied to other variations without departing from the scope of this disclosure. Therefore, this disclosure is not limited to the examples and designs described herein, but should be granted the widest scope consistent with the principles and novel features disclosed herein.
