Technical Field

[0003] The following relates to wireless communication, including techniques for indicating the time and frequency location of subband full-duplex (SBFD) subbands. 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] The described technology relates to improved methods, systems, devices, and apparatuses for supporting techniques for indicating the time and frequency positions of subband full-duplex (SBFD) subbands. Generally, the techniques described herein enable SBFD network entities to indicate one or more SBFD modes to one or more half-duplex user equipment (UEs) (which may be referred to as SBFD UEs), the one or more SBFD modes indicating the time position, frequency position, or both of the SBFD subband. For example, the UE may receive first configuration information indicating a transmission direction mode for multiple transmission time intervals (such as multiple time slots or multiple symbols within time slots). The transmission direction mode may define one or more downlink transmission time intervals, one or more flexible transmission time intervals, or any combination thereof for the multiple transmission time intervals. Additionally, the UE may receive second control information indicating one or more SBFD modes (e.g., for network entities). In some cases, the one or more SBFD modes may include one or more SBFD time slot modes, wherein each SBFD time slot mode indicates whether each symbol within a time slot is an SBFD symbol or a non-SBFD symbol. Additionally or alternatively, the one or more SBFD modes may include SBFD window modes, wherein the SBFD window mode indicates the duration of a window that includes SBFD symbols or SBFD time slots. Additionally or alternatively, the one or more SBFD modes may include SBFD frequency modes, wherein the SBFD frequency modes indicate frequency resources associated with SBFD time slots. Although described as SBFD symbols and SBFD time slots, it should be understood that for a half-duplex (HD) UE, an SBFD symbol or SBFD time slot (e.g., from the perspective of a network entity) allocates one or more uplink subbands or one or more downlink subbands to the UE. Therefore, the UE may communicate with a network entity based on applying one of the one or more SBFD modes to at least one subgroup of multiple transmission time intervals.

[0068] In some wireless communication systems, network entities can operate in Subband Full-Duplex (SBFD) mode. In this case, the network entity can communicate via SBFD symbols or SBFD slots, where the network entity can communicate via both one or more uplink subbands (e.g., uplink resources) and one or more downlink subbands (e.g., downlink resources) in each SBFD symbol or SBFD slot. In some cases, a UE (e.g., an SBFD-capable UE) can also operate in SBFD mode, such that the UE communicates with the network entity via both one or more uplink subbands and one or more downlink subbands in each SBFD symbol or SBFD slot. Conversely, a UE (e.g., an SBFD-aware UE) can operate in half-duplex (HD) mode, but is aware that the network entity is operating in SBFD mode. In this case, the network entity can indicate one or more SBFD symbols or SBFD slots to the HD UE; however, the UE can communicate via either uplink or downlink resources in each SBFD symbol or SBFD slot. Therefore, the UE may need to know the time and frequency location of one or more uplink subbands and one or more downlink subbands for each SBFD symbol or SBFD timeslot, so that the UE can adjust its behavior accordingly. However, conventional techniques may have limitations or require significant overhead.

[0069] Therefore, the techniques described herein can support indicating the time and frequency locations of SBFD subbands (e.g., one or more uplink subbands and one or more downlink subbands) of SBFD symbols or SBFD time slots to an SBFD-aware UE. For example, the SBFD-aware UE can receive configuration information indicating transmission directions for multiple transmission time intervals (such as multiple symbols or multiple time slots), where the transmission direction defines one or more downlink transmission time intervals, one or more uplink transmission time intervals, or both. Additionally, an SBFD network entity can send indications of one or more SBFD modes to the SBFD-aware UE (e.g., an HD UE). In some examples, the one or more SBFD modes may include one or more SBFD time slot modes, where each SBFD time slot mode indicates whether each symbol in the time slot is an SBFD symbol or a non-SBFD symbol. Additionally or alternatively, the one or more SBFD modes may include SBFD window modes, where the SBFD window mode indicates a window or duration that includes SBFD symbols or SBFD time slots. Additionally or alternatively, the one or more SBFD modes may include SBFD frequency modes, wherein the SBFD frequency modes indicate one or more uplink time slots, one or more downlink time slots, one or more guard bands, or any combination thereof of SBFD time slots. Thus, the UE may apply one or more SBFD modes to at least one subgroup of multiple transmission time intervals (e.g., symbols or time slots) and communicate with SBFD network entities based on this application.

[0070] The aspects of this disclosure are first described in the context of a wireless communication system. The aspects of this disclosure are then described in the context of SBFD window mode, SBFD frequency mode, and process flow. The aspects of this disclosure are further illustrated by apparatus diagrams, system diagrams, and flowcharts relating to techniques for indicating the time and frequency positions of SBFD sub-bands, and are described with reference to these diagrams.

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.

For example, a node may be UE 115. As another example, a node may be network entity 105. As another example, a first node may be configured to communicate with a second node or a 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.

[0075] 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. The backhaul communication link 120, midhaul communication link 162, or fronthaul communication link 168 may be 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, or may 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 may communicate with the core network 130 via communication link 155.

[0076] 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).

[0077] 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)).

[0078] 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.

[0079] 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.

[0080] In the context of applying the techniques described herein to a decomposed RAN architecture, one or more components of the decomposed RAN architecture may be configured to support techniques as described herein for indicating the time and frequency location of SBFD subbands. 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).

[0081] 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.

[0082] 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.

[0083] 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).

[0084] 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 a 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., over 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.

[0085] 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 resource 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).

[0086] 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.

[0087] 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)).

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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 this 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.

[0092] 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.

[0093] 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).

[0094] 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.

[0095] 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.

[0096] 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).

[0097] In some wireless communication systems, network entities can operate in Subband Full-Duplex (SBFD) mode. In this case, the network entity can communicate via SBFD symbols or SBFD slots, where the network entity can communicate via both one or more uplink subbands (e.g., uplink resources) and one or more downlink subbands (e.g., downlink resources) in each SBFD symbol or SBFD slot. In some cases, a UE (e.g., an SBFD-capable UE) can also operate in SBFD mode, such that the UE communicates with the network entity via both one or more uplink subbands and one or more downlink subbands in each SBFD symbol or SBFD slot. Conversely, a UE (e.g., an SBFD-aware UE) can operate in half-duplex (HD) mode, but is aware that the network entity is operating in SBFD mode. In this case, the network entity can indicate one or more SBFD symbols or SBFD slots to the HD UE; however, the UE can communicate via either uplink or downlink resources in each SBFD symbol or SBFD slot. Therefore, the UE may need to know the time and frequency location of one or more uplink subbands and one or more downlink subbands for each SBFD symbol or SBFD timeslot, so that the UE can adjust its behavior accordingly. However, conventional techniques may have limitations or require significant overhead.

[0098] The wireless communication system 200 may support techniques for indicating the time and frequency locations of SBFD subbands (e.g., one or more uplink subbands and one or more downlink subbands) of SBFD symbols or SBFD time slots to the SBFD-aware UE 115. For example, the SBFD-aware UE 115 may receive configuration information indicating transmission directions for multiple transmission time intervals (such as multiple symbols or multiple time slots), where the transmission direction defines one or more downlink transmission time intervals, one or more uplink transmission time intervals, or both. Additionally, the SBFD network entity 105 may send indications of one or more SBFD modes to the SBFD-aware UE 115 (e.g., HDUE 115). In some examples, the one or more SBFD modes may include one or more SBFD time slot modes, where each SBFD time slot mode indicates whether each symbol in the time slot is an SBFD symbol or a non-SBFD symbol. Additionally or alternatively, the one or more SBFD modes may include SBFD window modes, where the SBFD window mode indicates a window or duration that includes SBFD symbols or SBFD time slots. Additionally or alternatively, the one or more SBFD modes may include SBFD frequency modes, wherein the SBFD frequency modes indicate one or more uplink time slots, one or more downlink time slots, one or more guard bands, or any combination thereof. Therefore, UE 115 may apply one or more SBFD modes to at least one subgroup of multiple transmission time intervals (e.g., symbols or time slots) and communicate with SBFD network entity 105 based on this application.

[0099] Figure 2 Examples of wireless communication systems 200 supporting techniques for indicating the time and frequency location of SBFD sub-bands according to one or more aspects of this disclosure are shown. In some examples, wireless communication system 200 may implement or be implemented by aspects of wireless communication system 100. For example, wireless communication system 200 may include one or more network entities 105 (e.g., network entity 105-a) and one or more UEs 115 (e.g., UEs 115-a and 115-b), which may be referenced herein. Figure 1 Examples of the corresponding devices described.

[0100] In some wireless communication systems (such as wireless communication system 200), network entity 105 (such as network entity 105-a) may be able to operate according to SBFD mode (e.g., subband non-overlapping full-duplex). In such a case, network entity 105-a may configure both uplink resources (e.g., one or more uplink subbands 220) and downlink resources (e.g., one or more downlink subbands 215) for one or more time slots 205 (e.g., symbols 210). In such a case, time slot 205 may be referred to as SBFD time slot 205. For example, network entity 105-a may configure SBFD time slot 205 such that SBFD time slot 205 supports downlink subband 215, uplink subband 220, and downlink subband 215. In such a case, downlink subband 215 and uplink subband 220 may be separated by corresponding guard bands (e.g., no limitation on the frequency range of each subband or guard band). In another example, network entity 105-a may be configured with SBFD slot 205 such that SBFD slot 205 supports downlink subband 215 and uplink subband 220 (e.g., a single configured uplink BWP and downlink BWP pair with aligned center frequencies). In some examples, downlink subband 215 and uplink subband 220 may be separated by guard bands (e.g., no limitation on the frequency range of each subband or guard band). Thus, in each SBFD slot 205, network entity 105-a may communicate with a first UE 115 (such as UE 115-a) via downlink subband 215 and with a second UE 115 (such as UE 115-b) via uplink subband 220.

[0101] In some examples, network entity 105-a may support SBFD in TTD carriers (e.g., CC) or in-band CA (e.g., dynamic or flexible TDD). In such cases, network entity 105-a may support simultaneous transmission and reception of downlink and uplink communications, each according to its subband. In some examples, network entity 105-a operating according to SBFD mode may increase the uplink duty cycle, which may increase uplink coverage and reduce latency (e.g., uplink signals may be transmitted in uplink subband 220 in downlink-only or flexible time slot 205, or downlink signals may be received in downlink subband 215 in conventional uplink time slot 205). Additionally or alternatively, network entity 105-a operating according to SBFD mode may enhance system capacity, improve resource utilization, enhance spectrum efficiency, and provide flexible and dynamic uplink and downlink resource adaptation according to uplink and downlink traffic (e.g., in a robust manner), among other advantages.

[0102] In some (e.g., not depicted) examples, UE 115 may be able to operate according to SBFD mode. In such cases, UE 115 may be referred to as SBFD-capable UE 115. In other words, SBFD-capable UE 115 can simultaneously communicate with one or more network entities 105 (e.g., cells) in the same SBFD time slot 205 via downlink subband 215 and via uplink subband 220. Alternatively (e.g., depicted), UE 115 (such as UE 115-a (e.g., and UE 115-b)) may operate according to HD mode, but may be aware that network entity 105 (such as network entity 105-a) is operating according to SBFD mode. In such cases, UE 115-a may be referred to as SBFD-aware UE 115-a. In other words, SBFD-aware UE 115-a can communicate with network entity 105-a in the same SBFD time slot 205 via downlink subband 215 or via uplink subband 220.

[0103] In such cases, the SBFD-aware UE 115-a (e.g., in the RRC_CONNECTED state) may need to know both the time and frequency positions of the subbands used for SBFD operation in SBFD slot 205, so that the SBFD-aware UE 115-a can modify its behavior based on SBFD slot 205. That is, the SBFD-aware UE 115-a can be associated with different transmission behaviors (e.g., procedures), reception behaviors, measurement behaviors, or any combination thereof for and without SBFD slot 205. Additionally, the time and frequency positions (e.g., time domain positions and frequency domain positions) of one or more downlink subbands 215 and one or more uplink subbands 220 in SBFD slot 205 may not be fixed. Therefore, SBFD-aware UE 115-a may need to know both the time-domain and frequency-domain locations of one or more downlink subbands 215 and one or more uplink subbands 220 in SBFD slot 205 so that SBFD-aware UE 115-a can determine when and how to modify the behavior of SBFD-aware UE 115-a.

[0104] However, conventional techniques used to indicate the time-domain and frequency-domain locations of subbands (e.g., downlink subband 215 and uplink subband 220) of SBFD slot 205 may be flawed or lead to increased signaling overhead. For example, network entity 105-a may send a bitmap indicating whether each slot 205 configured for UE 115-a is an SBFD slot 205. In such cases, the bitmap has the same length and periodicity as the TDD uplink and downlink patterns and periodicity, resulting in increased signaling overhead.

[0105] Therefore, the techniques described herein enable a network entity 105 with SBFD capability (such as network entity 105-a) to indicate to an SBFD-aware UE 115 (such as UE 115-a) one or more SBFD modes associated with multiple transmission time intervals (such as time slots 205 or symbols 210). For example, network entity 105-a may send a control message 225-a to UE 115-a, which indicates configuration information associated with transmission direction modes for multiple time slots 205 (e.g., ...). tdd-UL- DL-configurationcommon or tdd-UL-DL-configurationdedicated That is, the transmission direction mode can indicate (e.g., for a given duration) whether each time slot 205 configured for UE 115-a is an uplink time slot 205, a downlink time slot 205, or a flexible time slot 205. In such cases, one or more downlink time slots 205, one or more flexible time slots 205, or both configured for UE 115-a can be SBFD time slots 205.

[0106] Additionally, UE 115-a can receive control message 225-b, which indicates one or more SBFD slot modes (e.g., higher-layer parameters, such as RRC parameters). TDD-UL-DL-SBFD-slot-pattern In such cases, each SBFD slot pattern may indicate a per-symbol-level time-domain configuration of whether each symbol 210 of SBFD slot 205 is an SBFD symbol 210 or a non-SBFD symbol 210 (e.g., a conventional symbol 210). In some cases, the indication of one or more SBFD slot patterns may be a symbol-level bitmap indication with the same length as SBFD slot 205. That is, each SBFD slot pattern may be associated with a bitmap 230 that indicates whether each symbol 210 of SBFD slot 205 is an SBFD symbol 210 or a non-SBFD symbol 210. For example, as... Figure 2 As depicted, SBFD slot 205 may include 14 symbols. Furthermore, each symbol 210 in SBFD slot 205 may be an SBFD symbol 210 (such as symbol 210-a) or a non-SBFD symbol 210 (such as symbol 210-b). Therefore, control message 225-b may include a bitmap 230 indicating that each non-SBFD symbol 210 is "0" and each SBFD symbol 210 is "1". In other words, for Figure 2 The SBFD slot 205 depicted may include a bitmap 00111111111100, which indicates that the SBFD slot 205 may include two non-SBFD symbols 210 at the beginning, followed by ten SBFD symbols 210, followed by two more non-SBFD symbols 210.

[0107] In some cases, UE 115-a may apply the indicated SBFD slot pattern (e.g., implicitly) to each downlink slot 205, flexible slot 205, or both configured as SBFD slot 205. In other words, each SBFD slot 205 configured for UE 115-a (e.g., all SBFD slots 205) may share the same SBFD slot pattern, where the same SBFD slot pattern is the indicated SBFD slot pattern. In other cases, UE 115-a may apply the indicated SBFD slot pattern to each downlink slot 205, flexible slot 205, or both configured as SBFD slot 205 during a time period (e.g., duration). That is, UE 115-a may (e.g., via SBFD slot mode) receive an indication of a start slot 205 (e.g., a first downlink slot 205 or a first flexible slot 205) and its length (e.g., duration) or a start slot 205 and an end slot 205, wherein the start slot 205 and its length or the start slot 205 and the end slot 205 define the time period. Therefore, UE 115-a may apply the indicated SBFD slot mode to each SBFD slot 205 in that time period (e.g., each downlink slot 205, flexible slot 205, or both configured as SBFD slot 205). In such cases, the start slot 205, the end slot 205, or both may be indicated via a corresponding index. Additionally or alternatively, the start slot 205 may be a first downlink slot 205 configured for UE 115-a (e.g., if the start slot 205 is not indicated or configured for UE 115-a).

[0108] In some cases, control message 225-b may include a bitmap 230 associated with an SBFD slot mode. In other cases, control message 225-b may include an index associated with the indicated SBFD slot mode. That is, network entity 105-a may (e.g., in control message 205) send indications of multiple SBFD slot modes and an index (e.g., bitmap 230) associated with each of the multiple SBFD slot modes. That is, network entity 105-a may configure (e.g., pre-configure) a table for UE 115-a containing different SBFD slot modes and an index associated with each SBFD slot mode. Therefore, control message 225-b may include an index associated with the SBFD slot pattern, such that UE 115-a can identify the indicated SBFD slot pattern based on the index and apply a bitmap 230 associated with the SBFD slot pattern to each SBFD slot 205 (e.g., all SBFD slots 205 in a time period or each SBFD slot 205).

[0109] In some cases, control message 225-b may indicate a corresponding index (e.g., associated with a corresponding SBFD slot mode) for each SBFD slot 205 configured for UE 115-a. That is, for each SBFD slot 205, control message 225-b may indicate an index associated with the SBFD slot mode, allowing UE 115-a to apply a different SBFD slot mode 205 for each SBFD slot 205. For example, control message 225-b may indicate that a first SBFD slot mode will be applied to a first SBFD slot 205, a second SBFD slot mode will be applied to a second SBFD slot 205, a first SBFD slot mode will be applied to a third SBFD slot 205, and a third SBFD slot mode will be applied to a fourth SBFD slot 205.

[0110] Additional or alternative locations, control message 225-b may indicate as referenced Figure 3 The SBFD window mode described, as shown in the reference Figure 4 The described SBFD frequency mode or both. Therefore, UE 115-a can communicate with network entity 105-a based on applying one or more SBFD slot modes, SBFD window modes, SBFD frequency modes, or any combination thereof to at least one subgroup of SBFD slots 205 configured for UE 115-a (e.g., one or more downlink slots 205, one or more flexible slots 205, or both). For example, as referenced... Figure 2 As described, UE 115-a can receive downlink communication from network entity 105-a via the first symbol 210 and the second symbol 210 of SBFD time slot 205, and can send uplink communication to network entity 105-a via the thirteenth symbol 210 (e.g., symbol 210-b) and the fourteenth symbol 210. Additionally, in some cases, network entity 105-a can allocate downlink subband 215 in SBFD symbol 210 (e.g., such as SBFD symbol 210-a) to UE 115-a, such that UE 115-a receives downlink communication from network entity 105-a via each of the third to twelfth symbols 210 of SBFD time slot 205. Alternatively, network entity 105-a may allocate uplink subband 220 in SBFD symbol 210 to UE 115-a, such that UE 115-a sends uplink communication to network entity 105-a via each of the third to twelfth symbols 210 of SBFD slot 205.

[0111] In some cases, each SBFD mode in one or more SBFD modes (e.g., SBFD slot mode, SBFD window mode, SBFD frequency mode) can be cell-common or UE-specific (e.g., UE-dedicated). Additionally or alternatively, one or more SBFD modes can be applied to (e.g., applicable to) a single CC or multiple CCs. Additionally or alternatively, network entity 105-a can broadcast, unicast, or multicast control messages 225-b indicating one or more SBFD modes. Additionally or alternatively, control message 225-b can be an RRC message, a Downlink Control Information (DCI) message, or a Media Access Control (MAC)-Control Element (MAC-CE) message.

[0112] Figure 3 Examples of SBFD window mode 300 supporting techniques for indicating the time and frequency location of SBFD subbands according to one or more aspects of this disclosure are shown. In some examples, SBFD window mode 300 may be implemented by or by aspects of wireless communication system 100, wireless communication system 200, or both. For example, SBFD window mode 300 may be implemented by one or more network entities 105 and one or more UEs 115, which may be referenced herein. Figure 1 Examples of the corresponding devices described.

[0113] As previously described, the techniques described herein enable a network entity 105 with SBFD capability to indicate to an SBFD-aware UE 115 one or more SBFD modes associated with multiple transmission time intervals (such as slot 310 or symbols). For example, network entity 105 may send to the SBFD-aware UE 115 an indication of one or more SBFD slot modes (e.g., higher-layer parameters, such as RRC parameters). TDD-UL-DL-SBFD-window-pattern Control messages for ). In such cases, each SBFD window mode can indicate the time window-level time domain configuration regarding each slot 310 (e.g., or symbol) in window 305 (e.g., time window, duration) as either an SBFD slot 310 (e.g., or SBFD symbol) or a non-SBFD slot 310 (e.g., or non-SBFD symbol). For example, as referenced Figure 3 As described, network entity 105 can send an indication of an SBFD window mode, wherein the SBFD window mode indicates that for window 305, time slots 310-a and 310-b are non-SBFD time slots 310, time slots 310-c to 310-d are SBFD time slots 310, and time slots 310-e and 310-f are non-SBFD time slots 310.

[0114] In some cases, control messages may indicate a bitmap associated with the SBFD window mode, where the bitmap indicates whether each slot 310 in window 305 is an SBFD slot 310 or a non-SBFD slot 310. For example, a control message may indicate a bitmap associated with window 305 where the bitmap indicates that each non-SBFD slot 310 in window 305 is "0" and each SBFD slot 310 in window 305 is "1". That is, in Figure 3 In the context of the control message, each time slot in time slots 310-a and 310-b can be set to "0", each time slot in time slots 310-c to 310-d can be set to "1", and each time slot in time slots 310-e and 310-f can be set to "0".

[0115] Additionally or alternatively, the control message may indicate a portion of window 305 that includes SBFD time slots 310. For example, the control message may indicate a starting time slot 310 and a length (e.g., duration), where the length includes the number of SBFD time slots 310. For example, time slots 310-c to 310-d may include 20 time slots. Thus, the control message may indicate time slot 310-c (e.g., as the starting time slot 310) and a length of 20 time slots. In some other examples, the control message may indicate an offset and a length (e.g., duration), where the length includes the number of SBFD time slots 310. For example, the control message may indicate an offset value of 3 (e.g., 3 time slots 310) and a length of 20 time slots.

[0116] In some cases, network entity 105 may (e.g., in a control message) send indications to SBFD-aware UE 115 for multiple SBFD window modes, where each SBFD window mode indicates a window 305 (e.g., duration) and each time slot 310 within the window 305 as either an SBFD time slot 310 or a non-SBFD time slot 310. Additionally, each SBFD window mode may be associated with a corresponding index. Therefore, network entity 105 may send control messages to SBFD-aware UE 115 indicating one or more indices associated with a corresponding SBFD window mode. For example, a control message may indicate that a first index associated with a first SBFD window mode will be applied by SBFD-aware UE 115. Additionally or alternatively, the control message may indicate periodicity associated with the SBFD window modes. In other words, each SBFD window mode may be periodic or repeatable. For example, a control message may instruct SBFD-aware UE 115 to apply the first SBFD window mode every 20 time slots 310.

[0117] Although described within the context of slot 310 in window 305, this should not be construed as a limitation of this disclosure. In this regard, as previously described, the SBFD window pattern can indicate whether each symbol in window 305 is an SBFD symbol or a non-SBFD symbol, allowing the techniques described herein to be applied at both symbol-level and slot-level granularity. For example, a control message can indicate a bitmap associated with the SBFD window pattern, wherein the bitmap indicates whether each symbol in window 305 is an SBFD symbol or a non-SBFD symbol. Additionally or alternatively, the control message can indicate for window 305 a portion of window 305 that includes SBFD symbols. For example, the control message can indicate a start symbol and length, or an offset value and length, wherein the length includes the number of SBFD symbols.

[0118] Figure 4 Examples of SBFD frequency mode 400, supporting techniques for indicating the time and frequency location of SBFD subbands according to one or more aspects of this disclosure, are shown. In some examples, SBFD frequency mode 400 may be implemented, or implemented by, aspects of, wireless communication system 100, wireless communication system 200, SBFD window mode 300, or any combination thereof. For example, SBFD frequency mode 400 may be implemented by one or more network entities 105 and one or more UEs 115, which may be referenced herein. Figure 1 Examples of the corresponding devices described.

[0119] As previously described, the techniques described herein enable a network entity 105 with SBFD capability to indicate to an SBFD-aware UE 115 one or more SBFD modes associated with multiple transmission time intervals (such as time slot 405 or symbol 410). For example, network entity 105 may send control messages (e.g., higher-layer parameters, such as RRC parameters) indicating the SBFD frequency mode to the SBFD-aware UE 115. TDD-UL-DL-SBFD-frequency-pattern or reuse TDD-UL-DL-SBFD- slot-pattern In such cases, the SBFD frequency pattern may indicate the frequency resources of one or more sub-bands in each SBFD slot 405 (e.g., or SBFD symbol 410). In other words, the SBFD frequency pattern may indicate the location (e.g., frequency location) of one or more downlink sub-bands 415, one or more guard bands 420, one or more sub-bands 425, or any combination thereof in the SBFD slot 405.

[0120] In some cases, the SBFD frequency mode may indicate frequency resources for uplink subband 425 and one or more downlink subbands 415 (such as downlink subband 415-a and downlink subband 415-b) in SBFD time slot 405. In some other cases, the SBFD frequency mode may indicate frequency resources for uplink subband 425 and one or more guard bands 420 (such as guard band 420-a and guard band 420-b) in SBFD time slot 405. In some still cases, the SBFD frequency mode may indicate uplink subband 425 (e.g., uplink subband 425 only) such that remaining resources (e.g., resource blocks) within SBFD time slot 405 are available for one or more guard bands 420 and one or more downlink subbands 415 (e.g., or uplink).

[0121] In such cases, the SBFD frequency mode may indicate the frequency resources of one or more downlink subbands 415, one or more guard bands 420, one or more subbands 425, or any combination thereof in SBFD slot 405. For example, in some cases, the SBFD frequency mode may indicate the starting resource block (e.g., an index associated with the starting resource block) and the number of resource blocks associated with each subband (e.g., each of one or more downlink subbands 415, one or more guard bands 420, one or more subbands 425, or any combination thereof). In some other cases, the SBFD frequency mode may indicate the starting resource block (e.g., an index associated with the starting resource block) and the ending resource block (e.g., an index associated with the ending resource block) associated with each subband.

[0122] Additionally or alternatively, the control message may indicate an index (e.g., a mode index) associated with an SBFD frequency mode. That is, network entity 105 may (e.g., via control messages) send indications of a plurality of SBFD frequency modes and an index associated with each of those SBFD frequency modes. Thus, network entity 105 may send control messages indicating indexes associated with SBFD frequency modes from the plurality of SBFD frequency modes. In some cases, a first index may be associated with a default SBFD frequency mode.

[0123] Figure 5An example of a process flow 500 supporting techniques for indicating the time and frequency location of SBFD subbands according to one or more aspects of this disclosure is shown. In some examples, process flow 500 may implement, or be implemented by, aspects of, wireless communication system 100, wireless communication system 200, SBFD window mode 300, SBFD frequency mode, or any combination thereof. For example, process flow 500 may include one or more network entities 105 (e.g., network entity 105-b) and one or more UEs 115 (e.g., UE 115-c), which may be referenced herein. Figure 1 Examples of the corresponding devices described.

[0124] At 505, network entity 105-b may send first configuration information to UE 115-c indicating a transmission direction mode for multiple transmission time intervals (e.g., multiple time slots, multiple micro-time slots, multiple symbols), wherein the transmission direction mode defines one or more downlink transmission time intervals, one or more flexible transmission time intervals, or a combination thereof for the multiple transmission time intervals.

[0125] In some cases, at 510, network entity 105-b may send an indication to UE 115-c for one or more SBFD mode groups, where each SBFD mode group includes multiple SBFD modes. For example, one or more SBFD mode groups may include an SBFD slot mode group with multiple SBFD slot modes, where each SBFD slot mode is associated with a corresponding index. Additionally or alternatively, one or more SBFD mode groups may include an SBFD window mode group with multiple SBFD window modes, where each SBFD window mode is associated with a corresponding index. Additionally or alternatively, one or more SBFD mode groups may include an SBFD frequency mode group with multiple SBFD frequency modes, where each SBFD frequency mode is associated with a corresponding index.

[0126] At point 515, network entity 105-b may (e.g., via RRC, DCI, or MAC-CE messages) send (e.g., broadcast, unicast, or multicast) to UE 115-c a second control information indicating (e.g., from multiple SBFD modes) one or more SBFD modes, wherein the one or more SBFD modes include: one or more SBFD slot modes, each indicating a symbol-level configuration of SBFD symbols within a slot; an SBFD window mode indicating a window duration including SBFD symbols or SBFD slots; an SBFD frequency mode indicating frequency resources associated with SBFD slots; or any combination thereof. In some cases, the one or more SBFD modes may be cell-common or UE-specific (e.g., UE-dedicated).

[0127] In some cases, the one or more SBFD modes may include one or more SBFD slot modes, wherein each SBFD slot mode indicates whether each symbol within the SBFD slot is an SBFD symbol or a non-SBFD symbol. For example, each SBFD slot mode may include a bitmap indicating that non-SBFD symbols in the SBFD slot are "0" and SBFD symbols in the SBFD slot are "1".

[0128] Additionally or alternatively, the one or more SBFD modes may include an SBFD window mode. In some cases, the SBFD window mode may indicate a bitmap defining the window duration, which indicates whether each symbol or time slot within the window duration is an SBFD symbol or an SBFD time slot. In some other cases, the SBFD window mode may indicate a first index associated with a first symbol or first time slot of the window duration, a second index associated with the last symbol or last time slot of the window duration, the number of symbols or time slots in the window duration, or any combination thereof.

[0129] Additionally or alternatively, the one or more SBFD modes may include SBFD frequency modes, wherein the SBFD frequency modes indicate one or more uplink subbands, one or more downlink subbands, one or more guard bands, or any combination thereof of SBFD time slots. In such cases, the second control information may indicate: one or more first resource block indices indicating the respective start of each downlink subband, uplink subband, or guard band; one or more second resource block indices indicating the respective end of each subband or guard band; the number of resource blocks in each subband or guard band; or any combination thereof. Additionally or alternatively, the second control information may indicate an index associated with an SBFD frequency mode (e.g., from a group of SBFD frequency modes). In some examples, the indicated SBFD frequency mode may be the default SBFD frequency mode.

[0130] In some cases, at 520, UE 115-c may apply one or more indicated SBFD modes to at least one subgroup of multiple transmission time intervals. In some cases, one or more SBFD modes may be applied to (e.g., applicable to) a single CC or multiple CCs. For example, one or more indicated SBFD modes may include SBFD slot modes, such that UE 115-c applies the SBFD slot mode to each of one or more downlink transmission time intervals, one or more flexible transmission time intervals, or combinations thereof. Alternatively, one or more indicated SBFD modes may include SBFD slot modes, such that UE 115-c applies the SBFD slot mode to a subgroup of multiple transmission time intervals. In such cases, the subgroup of transmission time intervals may be defined by a first transmission time interval, a duration (e.g., length), a last transmission time interval, or any combination thereof. Additionally, the first transmission time interval (e.g., a first index associated with the first transmission time interval), the duration, the last transmission time interval (e.g., a second index associated with the second transmission time interval), or any combination thereof may be indicated via second control information. In some cases, the first transmission time interval can be the first downlink transmission time interval among one or more downlink transmission time intervals.

[0131] In some cases, one or more indicated SBFD modes may include a first SBFD slot mode (e.g., a group of SBFD slot modes) and a second SBFD slot mode (e.g., a group of SBFD slot modes). In such cases, UE 115-c may apply the first SBFD slot mode to a first transmission time interval among multiple transmission time intervals based on a first index associated with the first SBFD slot mode indicated by second control information, and may apply the second SBFD slot mode to a second transmission time interval among multiple transmission time intervals based on a second index associated with the second SBFD slot mode indicated by second control information.

[0132] At 525, UE 115-c can communicate with network entity 105-b based on applying one or more SBFD slot patterns to at least one subgroup of multiple transmission time intervals. For example, for each SBFD symbol or SBFD slot, UE 115-c can communicate with network entity 105-b via one or more allocated uplink subbands or one or more allocated downlink subbands.

[0133] Figure 6A block diagram 600 illustrates a device 605 supporting techniques for indicating the time and frequency location of SBFD subbands according to one or more aspects of this disclosure. Device 605 may be an example of aspects of UE 115 as described herein. Device 605 may include a receiver 610, a transmitter 615, and a communication manager 620. Device 605, or one or more components of device 605 (e.g., receiver 610, transmitter 615, and communication manager 620), 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).

[0134] Receiver 610 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 associated with techniques used to indicate the time and frequency positions of SBFD subbands). Information may be passed to other components of device 605. Receiver 610 may utilize a single antenna or a group of multiple antennas.

[0135] Transmitter 615 may provide means for transmitting signals generated by other components of device 605. For example, transmitter 615 may transmit 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 associated with techniques used to indicate the time and frequency positions of SBFD subbands). In some examples, transmitter 615 may be co-located with receiver 610 in a transceiver module. Transmitter 615 may utilize a single antenna or a group of multiple antennas.

[0136] The communication manager 620, receiver 610, transmitter 615, or various combinations thereof, or various components thereof, may be examples of components used to perform various aspects of the techniques described herein for indicating the time and frequency positions of SBFD subbands. For example, the communication manager 620, receiver 610, transmitter 615, or various combinations thereof, or components thereof, may be able to perform one or more of the functions described herein.

[0137] In some examples, the communication manager 620, receiver 610, transmitter 615, 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).

[0138] Additionally or alternatively, the communication manager 620, receiver 610, transmitter 615, 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 620, receiver 610, transmitter 615, 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 components for performing the functions described in this disclosure).

[0139] In some examples, the communication manager 620 may be configured to use a receiver 610, a transmitter 615, or both, or otherwise cooperate with them to perform various operations (e.g., receiving, acquiring, monitoring, outputting, transmitting). For example, the communication manager 620 may receive information from the receiver 610, transmit information to the transmitter 615, or be integrated in combination with the receiver 610, the transmitter 615, or both to acquire information, output information, or perform various other operations as described herein.

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.

[0285] 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.

[0286] 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.

[0287] 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.

[0288] 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".

[0289] 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".

[0290] 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.

[0291] 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 numeral for differentiation between similar components. If only the first reference numeral is used in the specification, 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.

[0292] 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.

[0293] 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.
