[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).

[0062] Some wireless communication systems may include network entities and user equipment (UEs). In some examples, the network entity may operate in full-duplex (FD) or half-duplex (HD) mode, and the UE may operate in either FD or HD mode. When both the network entity and the UE are operating in FD mode, the network entity may configure the UE to simultaneously transmit in the uplink subband and receive in the downlink subband within an FD symbol or time slot. In some cases, the network entity may operate in FD or HD mode based on different conditions or use cases. Additionally, the network entity may configure the UE to be in FD or HD mode within a symbol or time slot based on different conditions or use cases. For example, if self-interference is high at a UE in FD mode, the UE may request the network entity to switch the UE from FD mode to HD mode. The network entity may also configure FD or HD mode based on downlink and service requirements. When a UE transitions from one mode to another, or a network entity transitions from one mode to another, the UE may need to modify its antenna configuration, RF tuning, and other operating parameters. Currently, there is no process for indicating a transition from one mode to another.

[0063] The technology used for transitioning from FD mode to HD mode can improve the operation of communication systems. In some examples, the UE can send control signaling to a network entity indicating its ability to operate in FD mode. The network entity can send control signaling to the UE indicating the network entity mode and UE mode for the delivery of one or more messages. The network entity mode can be FD mode or HD mode, and the UE mode can be FD mode or HD mode. The UE can deliver one or more messages based on the indicated network entity mode and the indicated UE mode. In some cases, the UE can receive from the network entity control signaling indicating the duration associated with the network entity mode, UE mode, or both. In some examples, the UE can send control signaling to the network entity indicating its ability to switch from wideband filter operation to narrowband filter operation, from narrowband filter operation to wideband filter operation, or both. Wideband filter operation can be associated with a bandwidth wider than that associated with narrowband filter operation. The UE can receive from the network entity control signaling to switch from FD symbols to HD symbols or from HD symbols to FD symbols. The UE can deliver messages in HD symbols or FD symbols by applying narrowband filter operation or wideband filter operation. The first bandwidth filter operation can be a wideband filter operation, and the second bandwidth filter operation can be a narrowband filter operation or a subband filter operation.

[0064] The aspects of this disclosure are first described in the context of wireless communication systems. The aspects of this disclosure are also described in the context of SBFD diagrams, HD and SBFD diagrams, and process flows. The aspects of this disclosure are further illustrated by apparatus diagrams, system diagrams, and flowcharts relating to techniques for transitioning from SBFD operation to HD operation, and are described with reference to these diagrams.

[0065] Figure 1 An example of a wireless communication system 100 supporting technologies for transitioning from FD operation to HD operation according to one or more aspects of this disclosure is shown. The wireless communication system 100 may include one or more devices, such as one or more network devices (e.g., network entity 105), one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating under other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.

[0066] 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 communication link 125 (e.g., a radio frequency (RF) access link). 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 communication link 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).

[0067] 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 Examples of UE 115 are illustrated herein. The UE 115 described herein may be able to support communication with various types of devices in the wireless communication system 100 (e.g., other wireless communication devices, including UE 115 or network entity 105), such as... Figure 1 As shown.

[0068] As described herein, a node in the wireless communication system 100 (which may be referred to as a network node or wireless node) may be a network entity 105 (e.g., any network entity described herein), a UE 115 (e.g., any UE described herein), a 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. 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.

[0069] 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 backhaul communication link 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 link 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) or 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) or 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.

[0070] One or more network entities or network equipment described herein as network entity 105 or network equipment 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 physically or logically integrated within a single network entity (e.g., network entity 105 or a single RAN node, such as base station 140).

[0071] 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 multiple network entities (e.g., network entity 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) such as CU 160, a Distributed Unit (DU) such as DU 165, a Radio Unit (RU) such as RU 170, a RAN Intelligent Controller (RIC) such as RIC 175 (e.g., a near real-time RIC (near RT RIC), a non-real-time RIC (non-RT RIC)), a Service Management and Orchestration (SMO) system such as SMO system 180, or any combination thereof. RU 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 in network entity 105 of a decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0072] 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, or 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 (e.g., one or more CUs) may connect to DU 165 (e.g., one or more DUs) or RU 170 (e.g., one or more RUs) or a combination thereof, and DU 165, RU 170, or both may 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 may each be at least partially controlled by CU 160. Additionally or alternatively, a protocol stack functional split may be employed between DU 165 and RU 170, such that DU 165 may support one or more layers of the protocol stack, and RU 170 may support one or more different layers of the protocol stack. DU 165 may (e.g., via one or more different RUs, such as RU 170) support one or more different cells. 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 a different one 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 DU 165 via midhaul communication link 162 (e.g., F1, F1-c, F1-u), and DU 165 can be connected to 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 corresponding network entities (e.g., one or more network entities in network entity 105) that communicate via such communication links.

[0073] In some wireless communication systems (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 of network entity 105 (e.g., network entity 105 or IAB node 104) may be partially controlled by each other. IAB node 104 may be referred to as a donor entity or IAB donor. DU 165 or RU 170 may be partially controlled by CU 160 associated with network entity 105 or base station 140 (such as a donor network entity or donor base station). One or more donor entities (e.g., IAB donors) may communicate with one or more additional devices (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 one or more DUs (e.g., DU 165) of a coupled IAB donor. The IAB-MT may be equipped with 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 one or more DUs (e.g., DU 165) that support 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., IAB node 104, or components of IAB node 104) may be configured to operate according to the techniques described herein.

[0074] When the techniques described herein are applied in the context of a decomposed RAN architecture, one or more components of the decomposed RAN architecture can be configured to support the tests 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., components such as IAB node, DU 165, CU 160, RU 170, RIC 175, SMO system 180).

[0075] 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, vehicles, or meters.

[0076] The UE 115 described herein may be able to communicate with various types of devices, such as other UEs 115 that may sometimes operate as repeaters, as well as network entities 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 As shown.

[0077] UE 115 and network entity 105 can wirelessly communicate with each other via communication link 125 (e.g., one or more 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 PHY 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 PHY layer channels for a given RAT (e.g., LTE, LTE-A, LTE-A Pro, NR). Each PHY layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating operation for the carrier, 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 can be configured using multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers. Communication between network entity 105 and other devices can refer to communication between these devices and any part of network entity 105 (e.g., entity, sub-entity). For example, the terms “send,” “receive,” or “communicate” when referring to network entity 105 can refer to any part of the RAN’s network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) communicating with another device (e.g., directly or via one or more other network entities, such as one or more network entities in network entity 105).

[0078] 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, where 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.

[0079] 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, in response This can represent the supported subcarrier spacing, and This can represent the supported Discrete Fourier Transform (DFT) size. The time interval for organizing communication resources can be based on 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).

[0080] 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, such as wireless communication system 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.

[0081] A subframe, time slot, micro-time slot, or symbol may be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and may 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) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0082] 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 UE 115 (e.g., one or more UEs), or it may include a UE-specific search space set configured to transmit control information to UE 115 (e.g., a particular UE).

[0083] 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 (such as coverage area 110). In some examples, coverage areas 110 associated with different technologies (e.g., different coverage areas) may overlap, but coverage areas 110 (e.g., different coverage areas) may be supported by the same network entity (e.g., network entity 105). In some other examples, overlapping coverage areas (such as coverage area 110) associated with different technologies may be supported by different network entities (e.g., network entity 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 RATs to support communication to coverage areas 110 (e.g., different coverage areas).

[0084] 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.

[0085] In some examples, UE 115 may be configured to support direct communication with other UEs (e.g., one or more UEs in UE 115) via a device-to-device (D2D) communication link (such as D2D communication link 135) (e.g., according to a peer-to-peer (P2P), D2D, or sidelink protocol). In some examples, one or more UEs 115 in a group performing D2D communication 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 UEs 115 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, a group of UEs 115 communicating via D2D communication can support a one-to-many (1:M) system, in which each UE 115 transmits to one or more UEs in the group. In some examples, network entity 105 can facilitate the scheduling of resources used for D2D communication. In some other examples, D2D communication can be performed between UEs 115 without involving network entity 105.

[0086] 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.

[0087] 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 one hundred kilometers).

[0088] Wireless communication system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, wireless communication system 100 may employ licensed assisted access (LAA), LTE-Unlicensed (LTE-U) RAT, or NR technology using unlicensed frequency bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). 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 frequency bands may be based on carrier aggregation configurations combined with component carriers operating with licensed frequency bands (e.g., LAA). Operation using unlicensed spectrum may include downlink transmission, uplink transmission, P2P transmission, or D2D transmission, etc.

[0089] 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.

[0090] 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).

[0091] Some wireless communication systems may include network entity 105 and UE 115. In some examples, the network entity may operate in either FD mode or HD mode, and the UE 115 may operate in either FD mode or HD mode. When both network entity 105 and UE 115 are operating in FD mode, network entity 105 may configure UE 115 to simultaneously transmit in the uplink subband and receive in the downlink subband within an FD symbol or time slot. In some cases, network entity 105 may operate in either FD mode or HD mode based on different conditions or use cases. Additionally, network entity 105 may configure UE 115 to be in either FD mode or HD mode within a symbol or time slot based on different conditions or use cases. For example, if self-interference is high at UE 115 in FD mode, UE 115 may request network entity 105 to switch the UE from FD mode to HD mode. Network entity 105 may also configure FD mode or HD mode based on downlink and service requirements. When UE 115 switches from one mode to another, or when network entity 105 switches from one mode to another, UE 115 may need to modify its antenna configuration, RF tuning, and other operating parameters. Currently, there is no process to indicate the transition from one mode to another.

[0092] The technology used for transitioning from FD mode to HD mode can improve the operation of a communication system. In some examples, UE 115 may send control signaling to network entity 105 indicating the ability to operate in FD mode. Network entity 105 may send control signaling to UE 115 indicating a network entity mode and UE mode for the delivery of one or more messages. The network entity mode can be FD mode or HD mode, and the UE mode can be FD mode or HD mode. UE 115 may deliver one or more messages based on the indicated network entity mode and the indicated UE mode. In some cases, UE 115 may receive from network entity 105 control signaling indicating the duration associated with the network entity mode, UE mode, or both. In some examples, UE 115 may send control signaling to network entity 105 indicating the ability to switch from wideband filter operation to narrowband filter operation, from narrowband filter operation to wideband filter operation, or both. Wideband filter operation may be associated with a bandwidth wider than that associated with narrowband filter operation. UE 115 can receive control signaling from network entity 105 to switch from FD symbols to HD symbols or from HD symbols to FD symbols. UE 115 can transmit messages in HD symbols or FD symbols by applying narrowband filter operations or wideband filter operations. The first wideband filter operation can be a wideband filter operation, and the second wideband filter operation can be a narrowband filter operation or a subband filter operation.

[0093] Figure 2 An example of a wireless communication system 200 supporting techniques for transitioning from FD operation to HD operation according to one or more aspects of this disclosure is shown. The wireless communication system 200 may implement, or be implemented by, aspects of the wireless communication system 100. For example, the wireless communication system 200 includes UE 115-a and UE 115-b, which may be examples of UE 115 as described herein. The wireless communication system 200 may also include network entity 105-a, which may be an example of network entity 105 as described herein.

[0094] UE 115-a can communicate with network entity 105-a using communication link 125-a. Communication link 125-a can be an example of an NR or LTE link (etc.) between UE 115-a and network entity 105-a. Communication link 125-a can include a bidirectional link that enables both uplink and downlink communication. For example, network entity 105-a can use communication link 125-a to send downlink signals (e.g., downlink transmissions) to UE 115-a, such as downlink control signaling 205-a and downlink data signaling 210-a, and UE 115-a can use communication link 125-a to send uplink signals (e.g., uplink transmissions) to network entity 105-a, such as uplink control signaling 215-a and uplink data signaling 220-a.

[0095] UE 115-b can communicate with network entity 105-a using communication link 125-b. Communication link 125-b can be an example of an NR or LTE link (etc.) between UE 115-b and network entity 105-a. Communication link 125-b can include a bidirectional link that enables both uplink and downlink communication. For example, network entity 105-b can use communication link 125-b to send downlink signals (e.g., downlink transmissions) to UE 115-b, such as downlink control signaling 205-b and downlink data signaling 210-b, and UE 115-b can use communication link 125-b to send uplink signals (e.g., uplink transmissions) to network entity 105-a, such as uplink control signaling 215-b and uplink data signaling 220-b.

[0096] Figure 3 An example of a subband full-duplex (SBFD) pattern 300 supporting a technique for transitioning from FD operation to HD operation is shown according to one or more aspects of this disclosure. Aspects of the SBFD pattern 300 may implement aspects of wireless communication system 100 and wireless communication system 200 or any combination thereof, or be implemented by these aspects.

[0097] In some examples, SBFD pattern 300 can be a downlink subband + uplink subband + downlink subband (D+U+D) pattern 305 or a downlink subband + uplink (D+U) pattern 310. D+U+D pattern 305 may include downlink subband 315-a, uplink subband 320-a, and downlink subband 315-b. A guard band 325-a may be introduced between downlink subband 315-a and uplink subband 320-a, and a guard band 325-b may be introduced between uplink subband 320-a and downlink subband 315-b. D+U pattern 310 may include downlink subband 315-c and uplink subband 320-b. A guard band 325-c may be introduced between downlink subband 315-c and uplink subband 320-b. Guard bands (e.g., guard band 325-a, guard band 325-b, guard band 325-c) may include a number of resource blocks. D+U+D pattern 305 and D+U pattern 310 may occupy time resources such as symbols, time slots, or other time resources; D+U+D pattern 305 and D+U pattern 310 may occupy frequency resources such as component carriers, bandwidth, or other frequency resources.

[0098] In some examples, network entity 105-a can operate in FD mode (such as SBFD mode) to simultaneously serve a downlink UE (e.g., UE 115-a) and an uplink UE (e.g., UE 115-b) on corresponding subbands. For example, network entity 105-a can serve UE 115-a on corresponding downlink subbands (e.g., downlink subbands 315-a and 315-b of D+U+D pattern 305 and downlink subband 315-c of D+U pattern 310), and network entity 105-a can serve UE 115-b on corresponding uplink subbands (e.g., uplink subbands 320-a and 320-b of D+U+D pattern 305 and D+U pattern 310). The SBFD mode in a TDD carrier or for network entity 105-a used for in-band carrier aggregation (CA) allows simultaneous transmission and reception of downlink and uplink signals on a subband basis. The increased uplink duty cycle can lead to reduced latency. For example, latency savings can be achieved by transmitting uplink signals in a traditional downlink or uplink subband in a flexible time slot, or receiving downlink signals in a downlink subband in a traditional uplink time slot. In some cases, SBFD mode can improve uplink coverage, enhancing system capacity, resource utilization, and spectral efficiency. In some examples, SBFD mode can robustly implement flexible and dynamic uplink or downlink resource adaptation based on uplink or downlink traffic. Full-duplex (FD) mode allows simultaneous transmission and reception of downlink and uplink signals in the same time slot.

[0099] In some examples, network entity 105-a may operate in either SBFD or HD network entity mode, and UEs (e.g., UE 115-a and UE 115-b) may operate in either SBFD or HD mode. SBFD mode operation can be extended to partially or fully overlapping FD mode operation. For the purposes of this discussion, SBFD mode will be used in the provided examples, and FD mode can also be applied to the examples discussed herein. In some examples, network entity 105-a may operate in HD mode, and UE 115-a may operate in HD mode (e.g., mode 1), and UE 115-a may communicate with the HD cell of network entity 105-a via uplink or downlink beams. In some examples, network entity 105-a can operate in SBFD mode, and UE 115-a and UE 115-b can operate in HD mode (e.g., mode 2). UE 115-a can communicate with the SBFD cell of network entity 105-a via a downlink beam, and UE 115-b can communicate with the SBFD cell using an uplink beam. In some examples, network entity 105-a can operate in SBFD mode, and UE 115-a can operate in SBFD mode (e.g., mode 3). UE 115-a can communicate with the SBFD cell of network entity 105-a via both uplink and downlink beams. In some examples, network entity 105-a can operate in FD mode, and UE 115-a can operate in SBFD mode (e.g., mode 4). UE 115-a can communicate with the first HD TRP (or low-capacity HD cell) of network entity 105-a via uplink beams and with the second HD TRP (or low-capacity HD cell) of the network entity via downlink beams. From the UE's perspective, modes 3 and 4 can be considered the same, and if the two TRPs or cells are in the same cell or DU, these two modes can be transparent to UEs with SBFD capability (e.g., UE 115-a, UE 115-b). UE (e.g., UE 115-a, UE 115-b) SBFD operation can be extended to partially or fully overlapping UE FD operations.

[0100] In some cases, HD mode and SBFD mode for UEs (e.g., UE 115-a and UE 115-b) can coexist with some symbols or time slots that are semi-statically configured as SBFD symbols or time slots on traditional downlink or traditional flexible symbols, and other symbols or time slots can be configured as traditional HD symbols or time slots. For example, one or more modes (e.g., mode 1, mode 2, mode 3, and mode 4) can be configured in different symbols or time slots, or one or more modes can switch from one mode to another at a time or under certain conditions.

[0101] Figure 4 Examples of HD and SBFD patterns 400 supporting techniques for transitioning from FD operation to HD operation according to one or more aspects of this disclosure are shown. Aspects of the HD and SBFD patterns 400 may implement aspects of wireless communication system 100 and wireless communication system 200 or any combination thereof, or be implemented by such aspects.

[0102] In some examples, HD and SBFD patterns 400 may include HD pattern 405 and SBFD pattern 410. HD pattern 405 may include downlink symbol 415-a, downlink symbol 415-b, downlink symbol 415-c, downlink symbol 415-d, and uplink symbol 420. SBFD patterns may include downlink subband 425-a, uplink subband 430-a, downlink subband 425-b, downlink subband 425-c, uplink subband 430-b, downlink subband 425-d, downlink subband 425-e, uplink subband 430-c, downlink subband 425-f, downlink subband 425-g, uplink subband 430-d, and downlink subband 425-h. In some examples, SBFD symbols may be configured on downlink symbols, or SBFD symbols may be configured on flexible symbols. HD pattern 405 and SBFD pattern 410 can occupy frequency resources such as component carriers, bandwidth, or other frequency resources.

[0103] In some examples, for SBFD-aware UEs (e.g., UE 115-a and UE 115-b) that are semi-statically configured with uplink subbands in an SBFD symbol configured as downlink in TDD-UL-DL-ConfigCommon, uplink transmission within the uplink subband may be permitted in that symbol, and uplink transmission outside the uplink subband may be disallowed. In some cases, the frequency location of the downlink subband may be known to the SBFD-aware UE, and the frequency location of the downlink subband may be explicitly indicated or implicitly derived. Downlink reception within the downlink subband may be permitted in that symbol. In that symbol, uplink transmission may be within the active uplink BWP, and downlink reception may be within the active downlink BWP.

[0104] In some examples, for SBFD operation in a symbol configured as a flexible symbol in TDD-UL-DL-ConfigCommon, SBFD-aware UEs (e.g., UE 115-a and UE 115-b) may be allowed to transmit uplink signals within the uplink subband of that symbol, and may not be allowed to transmit uplink signals outside the uplink subband of that symbol. In some cases, the frequency location of the downlink subband may be known to the SBFD-aware UE. Downlink reception within the downlink subband is allowed in that symbol. In that symbol, uplink transmission can be within the active uplink BWP, and downlink reception can be within the active downlink BWP.

[0105] In some examples, for SBFD operation in a symbol configured as a flexible symbol in TDD-UL-DL-ConfigCommon, SBFD-aware UEs (e.g., UE 115-a and UE 115-b) may be allowed to transmit uplink transmissions within the uplink subband of that symbol. From the perspective of network entity 105-a, resource blocks outside the uplink subband can be used as uplink or downlink in the exclusion guard band of that symbol, and the transmission direction of the resource blocks can be the same. In some cases, the frequency location of the downlink subband may be known to the SBFD-aware UE. Downlink reception within the downlink subband is allowed in that symbol. In that symbol, uplink transmission can be within the active uplink BWP, and downlink reception can be within the active downlink BWP. For all resource blocks outside the uplink subband, the UE (e.g., UE 115-a and UE 115-b) may not use a single resource block for both downlink and uplink simultaneously.

[0106] In some cases, UEs with SBFD capability (e.g., UE 115-a and UE 115-b) may be configured to transmit in the uplink subband and receive in the downlink subband simultaneously in SBFD symbols or time slots. In some examples, the SBFD network entity may not configure UEs with SBFD capability on all symbols or time slots at all times. Scheduling decisions may depend on different conditions. In some examples, the SBFD capability of a UE may be conditional or dynamic. For example, if self-interference at the UE becomes very high (e.g., due to clutter), a UE operating in SBFD mode (e.g., UE 115-a and UE 115-b) may request and instruct network entity 105-a to switch to UE HD mode (e.g., network entity 105-a may remain in SBFD mode). In another example, the network entity may configure SBFD mode or HD mode based on per-downlink or per-uplink traffic demand. For example, UE 115-a may have configuration permission that has a greater periodicity than semi-persistent scheduling traffic. Partial timings of the semi-persistent scheduling service of UE 115-a can be paired with the configuration permission of UE 115-a for SBFD operation, and other partial timings of the semi-persistent scheduling service of UE 115-a can be paired with the configuration permission of UE 115-b in SBFD mode, while UE 115-a can operate in HD mode. In some cases, UE 115-a may have a dominant service in one direction, and network entity 105-a may pair UE 115-a and UE 115-b for SBFD operation. In some examples, UE 115-a may have an urgent service to be transmitted, and network entity 105-a may pair UE 115-b with UE 115-a for SBFD operation performed by the network entity while UE 115-a and UE 115-b are in HD mode.

[0107] In some examples, network entity 105-a may indicate network entity mode and UE mode to UE 115-a. For example, network entity 105-a may indicate network entity mode as SBFD mode (or FD mode) and UE mode as HD mode, or network entity mode as SBFD mode (or FD mode) and UE mode as SBFD mode (or FD mode). When UE 115-a transitions from SBFD mode to HD mode, the UE may need to modify its antenna configuration. For example, UE 115 may use a full antenna array for HD mode, and UE 115-a may split the full antenna array into two separate arrays or panels for SBFD mode. When UE 115-a transitions from HD mode to SBFD mode, network entity 105 may configure two Transmit Configuration Indication (TCI) states for paired DL and UL transmissions, taking into account self-interference conditions. These two Transmit Configuration Indication (TCI) states may differ from the Best Reference Signal Received Quality (RSRP) TCI state for HD mode. In some cases, the uplink transmit power, modulation and decoding scheme (MCS), and operating parameters of the downlink or uplink beam configuration may differ for SBFD mode and HD mode. In some situations, the RF can be retuned for transitions from one mode to another (e.g., additional UE filters can be used in SBFD mode for self-interference mitigation). In some cases, UE 115-a in SBFD mode may have different subbands, frequency patterns, guard bands, and handover delays compared to network entity 105-a in SBFD mode.

[0108] In some examples, network entity 105-a may indicate to UE 115-a and UE 115-b the network entity mode and UE mode for the delivery of one or more messages. In some cases, UE 115-a may send control signaling 225-a to network entity 105-a indicating the ability to operate in SBFD mode (or FD mode). In some cases, UE 115-b may send control signaling 225-b to network entity 105-a indicating the ability to operate in SBFD mode (or FD mode).

[0109] In some examples, network entity 105-a may send control signaling 230-a to UE 115-a indicating the network entity mode and UE mode for the delivery of one or more messages (e.g., message 235-a or message 240-a). In some cases, network entity 105-a may send control signaling 230-b to UE 115-b indicating the network entity mode and UE mode for the delivery of one or more messages (e.g., message 235-b or message 240-b). In some examples, control signaling 230-a and control signaling 230-b may indicate to a UE with SBFD capability whether it is operating in UE HD mode or UE FD mode. In some examples, control signaling 230-a and control signaling 230-b may be one or two bits of downlink control information (DCI) or group common DCI, RRC signaling with a “duplex mode” field, or one or two bits of MAC control element (CE). In some examples, control signaling 230-a and 230-b can provide a semi-static indication of the baseline network entity mode and UE mode via RRC signaling. In some examples, control signaling 230-a and 230-b can provide dynamic backoff SBFD signaling, where whether it is based on duration, period, window, or time slot is yet to be determined. For example, UE 115-a can receive control signaling from network entity 105-a indicating the duration associated with the network entity mode, UE mode, or both. In some cases, the FD mode can be an SBFD mode, a partially overlapping FD mode, or a fully overlapping FD mode.

[0110] In some examples, UE 115-a may receive dynamic indications of network entity mode and UE mode as UE SBFD mode and network entity SBFD mode or UE HD mode and network entity SBFD mode. These dynamic indications may be provided to a single UE (e.g., UE 115-a or UE 115-b) or a group of UEs (e.g., UE 115-a and UE 115-b). In some cases, UE 115-a and UE 115-b may share the same beam pair with high self-interference.

[0111] In some cases, when UE 115-a is configured with a downlink channel, uplink channel, or reference signal at a higher layer, UE 115-a (or UE 115-b) may transition from FD mode to HD mode based on an indicated change from UE SBFD mode to UE HD mode (e.g., a fallback operation from FD mode to HD mode). For example, when control signaling 230-a indicates a change in UE mode from SBFD mode to HD mode and the network entity mode is SBFD mode, UE 115-a may transmit messages on the uplink channel or downlink channel based on a prioritized transmission direction (e.g., message 235-a or message 240-a), which may be based on canonical rules such as prioritizing the uplink channel (e.g., prioritizing one direction).

[0112] In some examples, when control signaling 230-a indicates a change in UE mode from SBFD mode to HD mode and the network entity mode is SBFD mode, UE 115-a may communicate messages based on channel type or reference signal type (e.g., message 235-a or message 240-a). For example, at least some channel types may be prioritized, and at least some reference signal types may be prioritized, such as RO if UE 115-a is configured with semi-persistent scheduling and random access (RO).

[0113] In some examples, when control signaling 230-a indicates a change in UE mode from SBFD mode to HD mode and the network entity mode is SBFD mode, UE 115-a may receive an indication of priority associated with a channel, channel type, or reference signal type from network entity 105-a, and UE 115-a may deliver messages (e.g., message 235-a or message 240-a) based on the indicated priority. For example, network entity 105-a may send control signaling to UE 115-a indicating a priority associated with a channel, and UE 115-a may deliver messages on the channel based on that priority. In some cases, the priority indication may be an RRC configuration, the priority indication may be included in fallback signaling (e.g., control signaling indicating a change in UE mode), or the priority indication may be included in separate control signaling.

[0114] In some examples, when control signaling 230-a indicates a change in UE mode from SBFD mode to HD mode and the network entity mode is SBFD mode, UE 115-a may avoid delivering messages (e.g., message 235-a or message 240-a). For example, UE 115-a may discard an uplink message, a downlink message, or both. In some examples, when control signaling 230-a indicates a change in UE mode from SBFD mode to HD mode and the network entity mode is SBFD mode, UE 115-a may prioritize one message or discard both messages based on UE 115-a's parameter adaptation capabilities. For example, UE 115-a may decide to discard an uplink message, a downlink message, or both based on UE capabilities.

[0115] In some examples, a UE with SBFD capability can receive instructions to operate in UE HD mode or UE FD mode. In some cases, network entity 105-a can send control signaling to UE 115-a to indicate UE SBFD mode and network entity SBFD mode or UE HD mode and network entity HD mode. The instructions can be provided to a single UE (e.g., UE 115-a or UE 115-b) or a group of UEs. In some cases, the instructions can be provided to a group of UEs or cell-shared UEs via RRC signaling, such as when a network entity suffers high self-interference due to clutter on the omnidirectional beam.

[0116] In some cases, UE 115-a (or UE 115-b) can transition from UE SBFD mode to UE HD mode, and network entity 105-a can transition from network entity SBFD mode to network entity HD mode (e.g., a fallback operation from SBFD mode to HD mode). In some examples, if the fallback is to a legacy uplink symbol, the downlink can be discarded. For example, control signaling can indicate a change in network entity mode from SBFD mode to HD mode, a change in UE mode from SBFD mode to HD mode, a change in FD time slot to uplink time slot, and the messages are both uplink and downlink messages. UE 115-a can transmit uplink messages in the uplink time slot and can avoid transmitting downlink messages in the uplink time slot.

[0117] In some examples, if the fallback is to a traditional downlink symbol, the uplink can be discarded. For example, control signaling can indicate a change in network entity mode from SBFD mode to HD mode, a change in UE mode from SBFD mode to HD mode, a change in FD time slot to downlink time slot, and the message is both an uplink message and a downlink message. UE 115-a can transmit downlink messages in the downlink time slot and can avoid transmitting uplink messages in the downlink time slot.

[0118] In some examples, if the fallback is to a traditional flexible symbol, both downlink and uplink messages configured at a higher layer can be discarded. For instance, control signaling may indicate a change in network entity mode from SBFD to HD mode, a change in UE mode from SBFD to HD mode, or a change in FD time slot to flexible time slot, and the messages are both uplink and downlink messages. UE 115-a can deliver either a downlink message or an uplink message in a flexible time slot, and can avoid delivering the other of the uplink or downlink message in a flexible time slot. In some cases, UE 115-a may avoid delivering both downlink and uplink messages in a flexible time slot.

[0119] In some examples, control signaling indicating network entity mode and UE mode (e.g., control signaling 230-a and control signaling 230-b) may include two or more bits, and these two or more bits may indicate network entity mode and UE mode. For example, two bits may be used to indicate UE mode and network entity mode, wherein a value of "00" indicates that network entity 105-a and UE 115-a switch from any other network entity mode and UE mode to UE SBFD mode and network entity SBFD mode, a value of "01" indicates that network entity 105-a and UE 115-a switch from any other network entity mode and UE mode to UE HD mode and network entity SBFD mode, and a value of "10" indicates that network entity 105-a and UE 115-a switch from any other network entity mode and UE mode to UE HD mode and network entity HD mode.

[0120] Figure 5 Examples of HD and SBFD patterns 500 supporting techniques for transitioning from FD operation to HD operation according to one or more aspects of this disclosure are shown. Aspects of the HD and SBFD patterns 500 may implement aspects of wireless communication system 100 and wireless communication system 200 or any combination thereof, or be implemented by these aspects.

[0121] In some examples, HD pattern and SBFD pattern 500 may include HD pattern 505, SBFD pattern 510, and SBFD pattern 515. HD pattern 505 may include flexible symbols 520-a, 520-b, 520-c, 520-d, and uplink symbol 525. SBFD pattern 510 may include flexible subband 530-a, uplink subband 535-a, flexible subband 530-b, flexible subband 530-c, uplink subband 535-b, flexible subband 530-d, flexible subband 530-e, uplink subband 535-c, flexible subband 530-f, flexible subband 530-g, uplink subband 535-d, and flexible subband 530-h. In some examples, the SBFD symbol of SBFD pattern 510 may be configured on the flexible symbol of HD pattern 505. SBFD pattern 515 may include downlink subband 540-a, uplink subband 545-a, downlink subband 540-b, downlink subband 540-c, uplink subband 545-b, downlink subband 540-d, uplink subband 545-c, uplink subband 545-d, uplink subband 545-e, downlink subband 540-e, uplink subband 545-f, and downlink subband 540-f. In some examples, the SBFD symbol of SBFD pattern 515 may be configured on the symbol of SBFD pattern 510 or the symbol of HD pattern 505. HD pattern 505, SBFD pattern 510, and SBFD pattern 515 may occupy frequency resources such as component carriers, bandwidth, or other frequency resources.

[0122] For a UE in SBFD or FD mode, UE 115-a can operate in narrowband in an uplink subband of an SBFD symbol (e.g., uplink subband 535-a), or in wideband in a conventional uplink symbol (e.g., uplink symbol 525). In some cases, UE 115-a can operate in narrowband in an downlink subband of an SBFD symbol with a D+U configuration, or in wideband in a conventional downlink symbol. When UE 115-a transitions from SBFD mode to HD mode or from HD mode to SBFD mode, UE 115-a can switch from narrowband filter operation or subband filter operation to wideband filter operation or vice versa. For example, UE 115-a can switch from narrowband filter operation for uplink subbands of SBFD symbols to wideband filter operation for traditional uplink symbols, and UE 115-a can switch from wideband filter operation for traditional uplink symbols to narrowband filter operation for uplink subbands of SBFD symbols.

[0123] In some examples, as a general UE capability, UE 115-a (e.g., an SBFD UE, an FD UE, or an SBFD-aware UE) may indicate to network entity 105-a that UE 115-a supports wideband to subband or narrowband filter switching capability and supports subband or narrowband to wideband filter switching capability. For example, UE 115-a may send control signaling to network entity 105-a indicating the capability to switch from a first bandwidth filter operation to a second bandwidth filter operation, from a second bandwidth filter operation to a first bandwidth filter operation, or both. The first bandwidth filter operation may be associated with a first bandwidth, which is wider than the second bandwidth associated with the second bandwidth filter operation. In some cases, the first bandwidth filter operation is a wideband filter operation, and the second bandwidth filter operation is a narrowband filter operation or a subband filter operation.

[0124] In some cases, UE 115-a may indicate, based on UE capabilities, whether a handover from wideband to narrowband or subband, or from narrowband or subband to wideband, can have a time slot or not. In some cases, the handover may be semi-static or a dynamic handover via scheduling for SBFD symbols configured on legacy downlink symbols or flexible symbols. In some examples, network entity 105-a may instruct UE 115-a to apply a wideband filter (e.g., one with less self-interference impact, or one that dynamically switches to a wideband or subband filter with greater self-interference impact at the cost of additional time slots). In some cases, network entity 105-a may instruct UE 115-a to apply a narrowband filter.

[0125] For a UE operating in SBFD or FD mode, UE 115-a can operate in narrowband (e.g., in the uplink subband of an SBFD symbol) or in wideband (e.g., in a traditional uplink symbol). In another example, UE 115-a can operate in narrowband (e.g., in the downlink subband of an SBFD symbol with a D+U configuration) or in wideband (e.g., in a traditional D symbol). As a general capability, an SBFD UE or FD UE can indicate to network entity 105-a that UE 115-a supports wideband-to-subband or narrowband handover capability and subband or narrowband-to-wideband handover capability. For SBFD symbols configured on flexible symbols, if there is no filter switching within the flexible symbol, UE 115-a guarantees subband or narrow filter operation in the SBFD symbol (e.g., a flexible symbol with a D+U+D configuration).

[0126] In some examples, for SBFD symbols configured on flexible symbols, the slot type can change at the boundary between SBFD and non-SBFD symbols if there is no filter switching within the flexible symbol. For SBFD symbols, the slot type may not switch from D+U+D to uplink because the narrowband filter is set to fixed within the SBFD symbol. In some cases, network entity 105-a may indicate to UE 115-a whether a wideband filter or a narrowband filter is applied within the SBFD symbol. For example, network entity 105-a may send control signaling, such as RRC signaling or MAC-CE, indicating whether a wideband or narrowband filter is applied within the SBFD symbol based on traffic or the UE's self-interference cancellation capability (e.g., a narrowband transmission uplink filter may or may not be used for self-interference mitigation).

[0127] In some examples, narrowband or subband filtering and wideband filtering can be extended to uplink filter switching in SBFD operation. For example, one downlink subband and one uplink subband, or one uplink subband and two downlink subbands, can be switched to the entire uplink symbol configuration for non-SBFD operation. In some examples, narrowband or subband filtering and wideband filtering can be extended to downlink filter switching in SBFD operation. For example, one downlink subband and one uplink subband can be switched to the entire downlink configuration for non-SBFD operation. UE 115-a can indicate a filter capability for both uplink and downlink filters, or indicate separate uplink and downlink filter capabilities.

[0128] In some examples, UE 115-a may receive control signaling from network entity 105-a to switch from an FD symbol to an HD symbol or vice versa. UE 115-a may communicate messages in HD symbols or FD symbols by applying wideband filter operations or narrowband or subband filter operations. For example, control signaling may indicate a change from an FD symbol to an HD symbol, and UE 115-a may communicate messages in HD symbols by applying wideband filter operations.

[0129] In some examples, control signaling can schedule a flexible symbol as an SBFD symbol, and the UE can receive control signaling indicating whether to apply a wideband filter operation or a narrowband filter operation within the SBFD symbol. In some cases, control signaling can schedule a flexible symbol as an SBFD symbol, and for a flexible symbol, the UE can avoid switching from a wideband filter operation to a narrowband filter operation or vice versa. In some cases, control signaling can schedule a flexible symbol as an SBFD symbol, and the UE can convey messages within the SBFD symbol by applying either a narrowband filter operation or a subband filter operation.

[0130] In some examples, control signaling can change a semi-static SBFD symbol configured on a flexible symbol to a conventional uplink symbol, or a semi-static SBFD symbol configured on a downlink symbol with uplink subbands to a conventional uplink symbol, and the UE can receive control signaling indicating which of the following operations—wideband filter operation or narrowband filter operation—is applied within the uplink symbol. In some cases, for uplink symbols, UE 115-a can avoid switching from wideband filter operation to narrowband filter operation or vice versa. In some cases, UE 115-a can convey messages within the uplink symbol by applying either narrowband filter operation or subband filter operation.

[0131] In some examples, control signaling can change an SBFD symbol configured on a flexible symbol (e.g., with a downlink subband) to a conventional downlink symbol, or a semi-static SBFD symbol configured on a downlink symbol (e.g., with a downlink subband) to a conventional downlink symbol, and the UE can receive control signaling indicating which of the following operations—wideband filter operation or narrowband filter operation—is applied within the symbol. In some cases, for uplink symbols, the UE can avoid switching from wideband filter operation to narrowband filter operation or vice versa. In some cases, UE 115-a can communicate messages in uplink symbols by applying either narrowband filter operation or subband filter operation.

[0132] Figure 6 An example of a process flow 600 supporting a technique for transitioning from FD operation to HD operation, according to one or more aspects of this disclosure, is shown. In some examples, process flow 600 may implement as described in reference respectively. Figure 1 and Figure 2 The described aspects of the wireless communication systems 100 and 200, or aspects implemented by these aspects. For example, process flow 600 may be implemented by network entity 105-b, which may be as described in the reference. Figure 1 and Figure 2 An example of network entity 105 as described. Process flow 600 can be implemented by UE 115-b, which can be as described in the reference. Figure 1 and Figure 2 An example of a UE as described.

[0133] In some examples, the operations illustrated in process flow 600 may be performed by hardware (e.g., including circuits, processing blocks, logic components, and other components), code such as processor-executable code (e.g., software executed by a processor), or any combination thereof. Alternative examples are possible, 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.

[0134] At 605, UE 115-c may send a first control signaling to network entity 105-b indicating the ability to operate in FD mode.

[0135] At 610, UE 115-c may receive, at least in part, second control signaling from network entity 105-b, indicating a network entity mode and UE mode for the delivery of one or more messages, based on a first control signaling. The network entity mode may be FD mode or HD mode, and the UE mode may be FD mode or HD mode. In some examples, the FD mode may be SBFD mode, partially overlapping FD mode, or fully overlapping FD mode. In some examples, the second control signaling may be DCI, group common DCI, RRC signaling, or MAC CE. In some examples, the second control signaling may be two or more bits, and these two or more bits may indicate the network entity mode and UE mode.

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.

[0296] 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 portions distributed such that the functions are implemented in different physical locations.

[0297] 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.

[0298] 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".

[0299] 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".

[0300] The term "determine" encompasses a variety of actions, and therefore, "determine" can include calculation, computation, processing, derivation, investigation, searching (such as by searching in a table, database, or other data structure), ascertainment, etc. 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.

[0301] 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 applies to any of the similar components having the same first reference numeral, regardless of the second reference numeral or other subsequent reference numerals.

[0302] 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 of the drawings, known structures and devices are shown in block diagram form to avoid obscuring the concept of the described examples.

[0303] 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.
