[0002] This patent application claims priority to U.S. Patent Application No. 18 / 533,078, filed December 7, 2023, entitled “USER EQUIPMENT CAPABILITY FOR SWITCHING BETWEEN FULL DUPLEX MODE AND HALF DUPLEX MODE”, assigned to the assignee of this application. The disclosure of the earlier application is considered part of this patent application and is incorporated herein by reference. Technical Field

[0003] All aspects of this disclosure relate to wireless communication in general, and more particularly to techniques, apparatus and methods for enabling user equipment to switch between full-duplex and half-duplex modes. Background Technology

[0004] Wireless communication systems are widely deployed to provide a variety of services, including voice, text, messaging, video, data, and / or other services. Services may include unicast, multicast, and / or broadcast services, etc. Typical wireless communication systems employ multiple access radio access technologies (RATs) capable of supporting communication with multiple users by sharing available system resources (e.g., time-domain resources, frequency-domain resources, spatial-domain resources, and / or device transmit power, etc.). Examples of such multiple access RATs include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single-Carrier Frequency Division Multiple Access (SC-FDMA) systems, and Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems.

[0005] The aforementioned Multiple Access RATs have been adopted in various telecommunications standards to provide a common protocol enabling different wireless communication devices to communicate at the city, national, regional, or global level. An example telecommunications standard is New Radio (NR). NR (which can also be referred to as 5G) is part of the continuous evolution of mobile broadband announced by the 3rd Generation Partnership Project (3GPP). NR (and other mobile broadband evolutions besides NR) can be designed to better support the deployment of Internet of Things (IoT) and degraded-capacity devices, industrial connectivity, millimeter-wave (mmWave) expansion, licensed and unlicensed spectrum access, non-terrestrial network (NTN) deployment, sidelinks and other device-to-device direct communication technologies (e.g., cellular vehicle-to-everything (CV2X) communication), massive MIMO, decomposed network architectures and network topology expansion, multi-subscriber implementations, high-precision positioning and / or radio frequency (RF) sensing, and more. As the demand for mobile broadband access continues to grow, further improvements to NR can be implemented, and other radio access technologies (such as 6G) can be introduced to further advance mobile broadband evolution.

[0038] The preceding paragraphs of this section have broadly summarized some aspects of this disclosure. These and additional aspects and their associated advantages will be described below. The disclosed aspects can serve as the basis for modifying or designing other aspects for performing the same or similar purposes of this disclosure. Such equivalent aspects do not depart from the scope of the appended claims. The characteristics of the aspects disclosed herein, their organization and operation, and their associated advantages will be better understood from the following description taken in conjunction with the accompanying drawings. Detailed Implementation

[0039] Various aspects of this disclosure are described below with reference to the accompanying drawings. However, aspects of this disclosure may be embodied in many different forms and should not be construed as limited to any specific aspect illustrated or described with reference to the drawings or otherwise presented in this disclosure. Rather, these aspects are provided so that this disclosure will be comprehensive and complete, and will fully convey the scope of this disclosure to those skilled in the art. Those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, various combinations or numbers of aspects set forth herein may be used to implement an apparatus or a practice. Furthermore, the scope of this disclosure is intended to cover apparatuses having structures and / or functionalities other than those available for practicing the various aspects of this disclosure set forth herein, or methods practiced using these other structures and / or functionalities. Any aspect of this disclosure disclosed herein may be embodied by one or more elements of the claims.

[0040] Various methods, operations, apparatuses, and techniques will now be presented with reference to them. These methods, operations, apparatuses, and techniques will be described in detail below and illustrated in the accompanying drawings by various boxes, modules, components, circuits, steps, processes, or algorithms (collectively, “elements”). These elements may be implemented using hardware, software, or a combination of hardware and software. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.

[0041] Various aspects relate to UE capabilities for switching between half-duplex (HD) and full-duplex (FD) communication modes. UE capabilities may include, for example, UE capability indications related to filter switching capabilities and / or spatial configuration switching capabilities. In some aspects, the network may configure and / or schedule resources based on UE capabilities, which can facilitate support for different communication modes at the UE. In some aspects, UE capabilities associated with switching between HD and FD communication may be indicated based on classification. In some aspects, different UE capabilities may be defined for different types of symbols. For example, a UE may have a first set of capabilities associated with flexible symbols and a second set of capabilities associated with semi-statically configured SBFD symbols and non-SBFD symbols. In some aspects, network nodes may send spatial configuration switching indications based on spatial configuration switching capability indications. In some aspects, spatial configuration switching rules may be indicated by wireless communication standards and thus maintained in one or more memories of the UE.

[0042] Specific aspects of the subject matter described in this disclosure can be implemented to achieve one or more of the following potential advantages. In some examples, the described techniques can be used to enable a UE configured for SBFD communication to communicate efficiently with a network node. Some aspects enable more efficient communication between the network node and the UE by configuring and / or scheduling resources based on UE capabilities (which facilitates support for different communication modes at the UE). Some aspects enable the network node to appropriately configure and / or schedule resources by indicating UE capabilities to the network node. Some aspects enable the network node to more efficiently configure its resources and components for communication based on the UE's HD mode or UE's FD mode by indicating spatial configuration switching capabilities.

[0043] Multiple access radio access technology (RAT) has been adopted in various telecommunications standards to provide a common protocol that enables wireless communication devices to communicate at the city, enterprise, national, regional, or global level. For example, 5G New Radio (NR) is part of the continuous mobile broadband evolution announced by the 3rd Generation Partnership Project (3GPP). 5G NR supports a variety of technologies and use cases, including enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), massive machine-type communication (mMTC), millimeter wave (mmWave) technology, beamforming, network slicing, edge computing, Internet of Things (IoT) connectivity and management, and network function virtualization (NFV).

[0044] With increasing demand for broadband access and the evolution of technologies supported by wireless communication networks, further technological improvements can be adopted in or implemented for 5G NR or future RATs (such as 6G) to further advance the evolution of wireless communication for a variety of existing and new use cases and applications. These technological improvements can be associated with new frequency band extensions, licensed and unlicensed spectrum access, overlapping spectrum use, small cell deployments, non-terrestrial network (NTN) deployments, decomposed network architectures and network topology extensions, device aggregation, advanced duplex communication, sidelinks and other device-to-device direct communication, IoT (including passive or ambient IoT) networks, reduced-capacity (RedCap) UE functionality, industrial connectivity, multi-subscriber implementations, high-precision positioning, radio frequency (RF) sensing and / or artificial intelligence or machine learning (AI / ML), and more. Such technological improvements can support use cases such as wireless backhaul, wireless data centers, extended reality (XR) and metaverse applications, meta-services for supporting vehicle connectivity, holographic and mixed reality communications, autonomous and collaborative robots, vehicle platooning and collaborative manipulation, sensor networks, posture monitoring, brain-computer interfaces, digital twin applications, asset management, and general coverage applications using off-ground and / or aerial platforms, etc. The methods, operations, apparatuses, and techniques described herein can implement one or more of the foregoing technologies and / or support one or more of the foregoing use cases.

[0045] Figure 1This is a diagram illustrating an example of a wireless communication network 100 according to the present disclosure. The wireless communication network 100 may be a 5G (or NR) network or a 6G network, or may include elements of a 5G (or NR) network or a 6G network, etc. The wireless communication network 100 may include a plurality of network nodes 110, shown as network node (NN) 110a, network node 110b, network node 110c, and network node 110d. Network nodes 110 may support communication with a plurality of UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e).

[0046] Network nodes 110 and UEs 120 of wireless communication network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, frequency bands, carriers, and / or channels according to frequency or wavelength. For example, devices of wireless communication network 100 can communicate using one or more operating frequency bands. In some aspects, multiple wireless networks 100 can be deployed in a given geographical area. Each wireless communication network 100 can support a specific radio access technology (RAT) (which may also be referred to as an air interface) and can operate on one or more carrier frequencies in one or more frequency ranges. Examples of RATs include 4G RAT, 5G / NR RAT, and / or 6G RAT, etc. In some examples, when multiple RATs are deployed in a given geographical area, each RAT in that geographical area can operate on a different frequency to avoid interference with each other.

[0047] Various operating frequency bands have been defined as frequency ranges designated FR1 (410 MHz to 7.125 GHz), FR2 (24.25 GHz to 52.6 GHz), FR3 (7.125 GHz to 24.25 GHz), FR4a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Although a portion of FR1 is greater than 6 GHz, in some documents and articles, FR1 is often (interchangeably) referred to as the “sub-6 GHz” band. Similarly, in some documents and articles, FR2 is often (interchangeably) referred to as the “millimeter wave” band, but this is different from the Very High Frequency (EHF) band (30 GHz to 300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU). The frequencies between FR1 and FR2 are often referred to as the mid-band frequencies, including FR3. Frequency bands falling within FR3 can inherit FR1 or FR2 characteristics, thereby effectively extending the characteristics of FR1 or FR2 into mid-band frequencies. Therefore, "below 6 GHz" (if used herein) can broadly refer to frequencies less than 6 GHz, within FR1, and / or included in mid-band frequencies. Similarly, the term "millimeter wave" (if used herein) can broadly refer to frequencies included in mid-band frequencies, within FR2, FR4, FR4-a, FR4-1, or FR5, and / or within the EHF band. Higher frequency bands can extend 5G NR operation, 6G operation, and / or other RATs above 52.6 GHz. For example, each of FR4a, FR4-1, FR4, and FR5 falls within the EHF band. In some examples, the wireless communication network 100 can implement dynamic spectrum sharing (DSS), where multiple RATs (e.g., 4G / LTE and 5G / NR) are implemented within a single frequency band using dynamic bandwidth allocation (e.g., based on user demand). It is conceivable that the frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1 and / or FR5) can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0048] Network node 110 may include one or more devices, components, or systems that enable communication between UE 120 and one or more devices, components, or systems of wireless communication network 100. Network node 110 may be, may include, or may also be referred to as an NR network node, 5G network node, 6G network node, node B, eNB, gNB, access point (AP), transmit / receive point (TRP), mobility element, core, network entity, network element, network equipment, and / or another type of device, component, or system included in a radio access network (RAN).

[0049] Network node 110 may be implemented as a single physical node (e.g., a single physical structure) or as two or more physical nodes (e.g., two or more different physical structures). For example, network node 110 may be a device or system implementing a portion of a radio protocol stack, a device or system implementing a complete radio protocol stack (such as a complete gNB protocol stack), or a collection of devices or systems collectively implementing a complete radio protocol stack. For example, and as shown, network node 110 may be an aggregated network node (with an aggregated architecture), meaning that network node 110 can implement a complete radio protocol stack physically and logically integrated within a single node (e.g., a single physical structure) in the wireless communication network 100. For example, aggregated network node 110 may consist of a single standalone base station or a single TRP that uses the complete radio protocol stack to implement or facilitate communication between UE 120 and the core network of wireless communication network 100.

[0050] Alternatively, and also as shown in the figure, network node 110 can be a decomposed network node (sometimes referred to as a decomposed base station), meaning that network node 110 can realize a radio protocol stack that is physically distributed and / or logically distributed among two or more nodes in the same or different geographic locations. For example, a decomposed network node may have a decomposed architecture. In some deployments, decomposed network node 110 may be used in integrated access and backhaul (IAB) networks, in open radio access networks (O-RAN) (such as network configurations compliant with the O-RAN Alliance), or in virtualized radio access networks (vRAN) (also referred to as cloud radio access networks (C-RAN)) to facilitate scaling by decomposing base station functionality into multiple units that can be deployed independently.

[0051] Network nodes 110 of the wireless communication network 100 may include one or more central units (CUs), one or more distributed units (DUs), and / or one or more radio units (RUs). CUs may host one or more higher-layer control functions, such as Radio Resource Control (RRC) functions, Packet Data Convergence Protocol (PDCP) functions, and / or Service Data Adaptation Protocol (SDAP) functions, etc. DUs may host one or more of the Radio Link Control (RLC) layer, Media Access Control (MAC) layer, and / or one or more higher physical (PHY) layers, at least in part, according to functional splits (such as functional splits defined by 3GPP). In some examples, DUs may also host one or more lower PHY layer functions, such as Fast Fourier Transform (FFT), Inverse FFT (iFFT), beamforming, Physical Random Access Channel (PRACH) extraction and filtering, and / or scheduling of resources for one or more UEs 120, etc. RUs may host RF processing functions or lower PHY layer functions, such as FFT, iFFT, beamforming, or PRACH extraction and filtering, etc., according to functional splits (such as lower-layer functional splits). In this type of architecture, each RU can be operated to handle over-the-air (OTA) communications with one or more UE 120s.

[0052] In some aspects, a single network node 110 may include a combination of one or more CUs, one or more DUs, and / or one or more RUs. Additionally or alternatively, network node 110 may include one or more near real-time (near RT) RAN Intelligent Controllers (RICs) and / or one or more non-real-time (non-RT) RICs. In some examples, CUs, DUs, and / or RUs may be implemented as virtual units, such as Virtual Central Units (VCUs), Virtual Distributed Units (VDUs), or Virtual Radio Units (VRUs), etc. Virtual units may be implemented as virtual network functions, such as those associated with cloud deployments.

[0053] Some network nodes 110 (e.g., base stations, RUs, or TRPs) can provide communication coverage for specific geographic areas. In 3GPP, the term "cell" can refer to the coverage area of ​​network node 110 or to network node 110 itself, depending on the context in which the term is used. Network node 110 can support one or more (e.g., three) cells. In some examples, network node 110 can provide communication coverage for macro cells, pico cells, femto cells, or another type of cell. A macro cell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UE 120 with a service subscription. A pico cell can cover a relatively small geographic area and can allow unrestricted access by UE 120 with a service subscription. A femto cell can cover a relatively small geographic area (e.g., a residential area) and can allow restricted access by UE 120 associated with that femto cell (e.g., UE 120 in a Closed Subscriber Group (CSG)). The network node 110 used for a macro cell may be referred to as a macro network node. Network node 110 used for a picocell may be referred to as a pico network node. Network node 110 used for a femtocell may be referred to as a femto network node or a home network node. In some examples, the cell may not necessarily be stationary. For example, the geographical area of ​​the cell may be mobile based on the location of the associated mobile network node 110 (e.g., a train, satellite base station, unmanned aerial vehicle, or non-terrestrial network (NTN) network node).

[0054] The wireless communication network 100 can be a heterogeneous network, comprising different types of network nodes 110, such as macro network nodes, piconet nodes, femtonet nodes, relay network nodes, aggregation network nodes, and / or decomposition network nodes, etc. Figure 1 In the example shown, network node 110a can be a macro network node for macro cell 130a, network node 110b can be a pico network node for pico cell 130b, and network node 110c can be a femto network node for femto cell 130c. Compared to other types of network nodes 110, the various types of network nodes 110 typically transmit at different power levels, serve different coverage areas, and / or have different effects on interference in the wireless communication network 100. For example, macro network nodes may have high transmit power levels (e.g., 5 watts to 40 watts), while pico network nodes, femto network nodes, and relay network nodes may have lower transmit power levels (e.g., 0.1 watts to 2 watts).

[0055] In some examples, network node 110 may be, may include, or operate as a RU, TRP, or base station communicating with one or more UEs 120 via a radio access link (which may be referred to as a "Uu" link). The radio access link may include a downlink and an uplink. A "downlink" (or "DL") refers to the communication direction from network node 110 to UE 120, and an "uplink" (or "UL") refers to the communication direction from UE 120 to network node 110. Downlink channels may include one or more control channels and one or more data channels. Downlink control channels may be used to transmit downlink control information (DCI) (e.g., scheduling information, reference signals, and / or configuration information) from network node 110 to UE 120. Downlink data channels may be used to transmit downlink data (e.g., user data associated with UE 120) from network node 110 to UE 120. Downlink control channels may include one or more physical downlink control channels (PDCCH), and downlink data channels may include one or more physical downlink shared channels (PDSCH). The uplink channel may similarly include one or more control channels and one or more data channels. The uplink control channel can be used to transmit uplink control information (UCI) from UE 120 to network node 110 (e.g., transmitting corresponding reference signals and / or feedback with one or more downlinks). The uplink data channel can be used to transmit uplink data (e.g., user data associated with UE 120) from UE 120 to network node 110. The uplink control channel may include one or more physical uplink control channels (PUCCH), and the uplink data channel may include one or more physical uplink shared channels (PUSCH). The downlink and uplink may each include a set of resources on which network node 110 and UE 120 can communicate.

[0056] Downlink and uplink resources may include time-domain resources (frames, subframes, time slots, and / or symbols), frequency-domain resources (bands, component carriers, subcarriers, resource blocks, and / or resource elements), and / or spatial-domain resources (specific transmission directions and / or beam parameters). Frequency-domain resources in some bands may be subdivided into bandwidth portions (BWPs). A BWP may be a contiguous block of frequency-domain resources allocated to one or more UEs 120 (e.g., a contiguous block of resource blocks). A UE 120 may be configured with both an uplink BWP and a downlink BWP (where the uplink BWP and downlink BWP may be the same BWP or different BWPs). BWPs may be dynamically configured and / or reconfigured (e.g., by sending DCI configuration to one or more UEs 120 via network node 110), meaning that BWPs may be adjusted in real-time (or near real-time) based on changing network conditions in the wireless communication network 100 and / or based on the specific requirements of one or more UEs 120. This allows for more efficient use of available frequency domain resources in the wireless communication network 100, as fewer frequency domain resources can be allocated to the BWP for UE 120 (which reduces the number of frequency domain resources that UE 120 needs to monitor), thus allowing more frequency domain resources to be distributed across multiple UE 120s. Therefore, the BWP can also assist in the implementation of such UE 120s by facilitating the configuration of smaller bandwidths for communications performed by lower-capacity UE 120s.

[0057] As described above, in some aspects, the wireless communication network 100 may be an IAB network, may include an IAB network, or may be included in an IAB network. In an IAB network, at least one network node 110 is an anchor network node communicating with a core network. The anchor network node 110 may also be referred to as an IAB donor (or "IAB donor"). The anchor network node 110 may be connected to the core network via a wired backhaul link. For example, the Ng interface of the anchor network node 110 may terminate at the core network. Additionally or alternatively, the anchor network node 110 may be connected to one or more devices in the core network that provide core access and mobility management functions (AMF). An IAB network typically also includes multiple non-anchor network nodes 110, which may also be referred to as relay network nodes or simply IAB nodes (or "IAB-nodes"). Each non-anchor network node 110 can directly communicate with the anchor network node 110 via a wireless backhaul link to access the core network, or can indirectly communicate with the anchor network node 110 via one or more other non-anchor network nodes 110 and an associated wireless backhaul link forming a backhaul path to the core network. Some anchor network nodes 110 or other non-anchor network nodes 110 can also directly communicate with one or more UEs 120 via a wireless access link carrying access services. In some examples, network resources used for wireless communication (such as time resources, frequency resources, and / or spatial resources) can be shared between the access link and the backhaul link.

[0058] In some examples, any network node 110 relaying communication may be referred to as a relay network node, a relay station, or simply a repeater. A repeater may receive communications from an upstream station (e.g., another network node 110 or UE 120) and transmit communications to a downstream station (e.g., UE 120 or another network node 110). In this case, the wireless communication network 100 may include or be referred to as a "multi-hop network." Figure 1 In the example shown, network node 110d (e.g., a relay network node) can communicate with network node 110a (e.g., a macro network node) and UE 120d to facilitate communication between network node 110a and UE 120d. Additionally or alternatively, UE 120 can be a relay station capable of relaying transmissions to or from other UE 120s, or can operate as such a relay station. UE 120 relaying communication can be referred to as a UE repeater or relay UE, etc.

[0059] UE 120 may be physically distributed throughout the wireless communication network 100, and each UE 120 may be stationary or mobile. UE 120 may be, may include, an access terminal, another terminal, a mobile station, or a subscriber unit, or may be included in an access terminal, another terminal, a mobile station, or a subscriber unit. UE 120 may be, or may include, a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet device, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smart wristband and / or smart jewelry (such as a smart ring or smart bracelet)), an entertainment device (e.g., a music device, a video device and / or a satellite radio), an extended reality (XR) device, a vehicle component or sensor, a smart meter or sensor, industrial manufacturing equipment, a Global Navigation Satellite System (GNSS) device (such as a Global Positioning System device or another type of positioning device), a UE function of a network node, and / or any other suitable device or function that can communicate via a wireless medium, or may be coupled to them.

[0060] UE 120 and / or network node 110 may include one or more chips, system-on-a-chip (SoC), chipsets, packages, or devices that individually or collectively constitute or include a processing system. The processing system includes processor (or “processing”) circuitry in the form of one or more processors, microprocessors, processing units (such as central processing units (CPUs), graphics processing units (GPUs), neural processing units (NPUs), and / or digital signal processors (DSPs)), processing blocks, application-specific integrated circuits (ASICs), programmable logic devices (PLDs) (such as field-programmable gate arrays (FPGAs)), or other discrete gate or transistor logic components or circuits (all of which are generally referred to herein individually as “processors” or collectively as “processors” or “processor circuitry”). One or more of these processors may be individually or collectively configured to perform the various functions or operations described herein. A group of processors that can be configured or configured to perform a set of functions may include a first processor that can be configured or configured to perform a first function in the set, and a second processor that can be configured or configured to perform a second function in the set, or may include the entire group of processors that are configured or configured to perform the set of functions.

[0061] The processing system may also include memory circuitry in the form of one or more memory devices, memory blocks, memory elements, or other discrete gate or transistor logic components or circuits, each of which may include tangible storage media such as random access memory (RAM) or read-only memory (ROM) or combinations thereof (all of which are generally referred to herein individually as "memory" or collectively as "memory" or "memory circuitry"). One or more of these memories may be coupled to one or more processors in the processor (e.g., operatively coupled, communicatively coupled, electronically coupled, or electrically coupled) and may store processor-executable code (such as software) individually or collectively, which, when executed by one or more processors in the processor, may configure one or more processors in the processor to perform the various functions or operations described herein. Additionally or alternatively, in some examples, one or more processors in the processor may be pre-configured to perform the various functions or operations described herein without being configured by software. The processing system may also include or be coupled to one or more modems (such as Wi-Fi (e.g., IEEE compliant) modems or cellular (e.g., 3GPP 4G LTE, 5G, or 6G compliant) modems). In some embodiments, one or more processors of the processing system include or implement one or more modems among the modems. The processing system may also include, or be coupled to, multiple radio components (collectively, “radio components”), multiple RF chains, or multiple transceivers, each of which may in turn be coupled to one or more antennas among multiple antennas. In some embodiments, one or more processors of the processing system include or implement one or more of the radio components, RF chains, or transceivers. UE 120 may be included or may be contained in a housing that houses components associated with UE 120, including the processing system.

[0062] Some UEs 120 may be considered Machine Type Communication (MTC) UEs, Evolved or Enhanced Machine Type Communication (eMTC) UEs, Further Enhanced eMTC (feMTC) UEs or Enhanced feMTC (efeMTC) UEs, or further evolutions thereof, all of which may be collectively referred to as "MTC UEs". MTC UEs may be, may include, or may be included in or coupled with the following: robots, unmanned aerial vehicles, remote devices, sensors, instruments, monitors, and / or location tags. Some UEs 120 may be considered IoT devices and / or may be implemented as NB-IoT (Narrowband IoT) devices. IoT UEs or NB-IoT devices may be, may include, or may be included in or coupled with the following: industrial machines, appliances, refrigerators, doorbell camera devices, home automation devices, and / or lighting fixtures, etc. Some UEs 120 may be considered customer premises equipment, which may include telecommunications equipment installed at a customer location (such as a home or office) to enable access to a service provider’s network (such as being included in or communicating with the wireless communication network 100).

[0063] Some UEs 120 can be categorized according to different categories associated with varying levels of complexity and / or capabilities. UEs 120 in the first category facilitate large-scale IoT within the wireless communication network 100 and offer lower complexity and / or lower cost compared to UEs 120 in the second category. UEs 120 in the second category may include mission-critical IoT devices, legacy UEs, baseline UEs, high-level UEs, advanced UEs, full-capability UEs, and / or premium UEs capable of ultra-reliable low-latency communication (URLLC), enhanced mobile broadband (eMBB), and / or precise positioning, etc., within the wireless communication network 100. UEs 120 in the third category may have intermediate-level complexity and / or capabilities (e.g., capabilities between UEs 120 in the first category and UEs 120 in the second category). UEs 120 in the third category may be referred to as reduced-capability UEs (“RedCap UEs”), intermediate-level UEs, NR lightweight UEs, and / or NR simplified UEs, etc. RedCap UEs bridge the gap in capabilities and complexity between NB-IoT devices and / or eMTC UEs and mission-critical IoT devices and / or premium UEs. RedCap UEs can include, for example, wearable devices, IoT devices, industrial sensors, and / or cameras associated with limited bandwidth, power capacity, and / or transmission range. RedCap UEs can support healthcare environments, building automation, power distribution, process automation, transportation and logistics, and / or smart city deployments, among others.

[0064] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly with each other using sidelink communication (e.g., without communication through a network node 110 acting as an intermediary). As an example, UE 120a can directly send data, control information, or other signaling to UE 120e as sidelink communication. This contrasts with, for example, UE 120a first sending data to network node 110 in UL communication, and then that network node sending data to UE 120e in DL communication. In various examples, UE 120 can use peer-to-peer (P2P) communication protocols, device-to-device (D2D) communication protocols, vehicle-to-everything (V2X) communication protocols (which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, and / or vehicle-to-pedestrian (V2P) protocols), and / or mesh network communication protocols to send and receive sidelink communication. In some deployments and configurations, network node 110 may schedule and / or allocate resources for sidelink communication between UEs 120 in the wireless communication network 100. In some other deployments and configurations, UE 120 (instead of network node 110) may perform or cooperate with or negotiate with one or more other UEs to perform scheduling operations, resource selection operations, and / or other operations for sidelink communication.

[0065] In various examples, in addition to half-duplex operation, some network nodes and UEs in the wireless communication network 100, including network node 110 and UE 120, can also be configured for full-duplex operation. Network node 110 or UE 120 operating in half-duplex mode can perform only one of transmission or reception during a specific time resource period (such as a specific time slot, symbol, or other time period). Half-duplex operation may involve time division duplex (TDD), where the DL transmission of network node 110 and the UL transmission of UE 120 do not occur in the same time resource (i.e., the transmissions do not overlap in time). In contrast, network node 110 or UE 120 operating in full-duplex mode can transmit and receive communications concurrently (e.g., within the same time resource). By operating in full-duplex mode, network node 110 and / or UE 120 can generally increase the capacity of the network and radio access links. In some examples, full-duplex operation may involve frequency division duplex (FDD), in which network node 110 performs DL transmission in a first frequency band or on a first component carrier, and UE 120 performs transmission in a second frequency band or on a second component carrier, the second frequency band or the second component carrier being different from the first frequency band or the first component carrier, respectively. In some examples, full-duplex operation may be enabled for UE 120 but not for network node 110. For example, UE 120 may simultaneously transmit UL to the first network node 110 and receive DL transmissions from the second network node 110 in the same time resources. In some other examples, full-duplex operation may be enabled for network node 110 but not for UE 120. For example, network node 110 may simultaneously transmit DL to the first UE 120 and receive UL transmissions from the second UE 120 in the same time resources. In some other examples, full-duplex operation may be enabled for both network node 110 and UE 120.

[0066] In some examples, UE 120 and network node 110 can perform MIMO communication. "MIMO" generally refers to the simultaneous transmission or reception of multiple signals (such as multiple layers or multiple data streams) using the same time and frequency resources. MIMO technology typically utilizes multipath propagation. MIMO can be implemented using various spatial processing or spatial multiplexing operations. In some examples, MIMO can support simultaneous transmission to multiple receivers, which is called multi-user MIMO (MU-MIMO). Some radio access technologies (RATs) can employ advanced MIMO techniques such as mTRP operation (including redundant transmission or reception on multiple TRPs), reciprocity in the time or frequency domain, single-frequency network (SFN) transmission, or noncoherent joint transmission (NC-JT).

[0067] In some aspects, the UE (e.g., UE 120) may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may transmit UE capability information associated with a subband full-duplex (SBFD) configuration, in which a set of flexible symbols is configured as SBFD symbols with subbands, wherein the UE capability information includes UE capability indications associated with switching between UE full-duplex mode and UE half-duplex mode; and communication in conjunction with the UE capability indications.

[0068] In some aspects, the communication manager 140 may send a channel state information (CSI) report associated with an SBFD configuration in which a set of flexible symbols is configured as SBFD symbols with uplink subbands, wherein the CSI report includes a first CSI feedback assumption associated with the UE full-duplex mode and a second CSI feedback assumption associated with the UE half-duplex mode; and receive configuration information in conjunction with the CSI report, which indicates a first set of transmission parameters for the first set of symbols associated with the UE full-duplex mode and a second set of transmission parameters for the second set of symbols associated with the UE half-duplex mode. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0069] In some aspects, a network node (e.g., network node 110) may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may receive UE capability information associated with an SBFD configuration, in which a set of flexible symbols is configured as SBFD symbols with subbands, wherein the UE capability information includes UE capability indications associated with handover between UE full-duplex mode and UE half-duplex mode; and communication in conjunction with the UE capability indications.

[0070] In some aspects, the communication manager 150 may receive a CSI report associated with an SBFD configuration, in which a set of flexible symbols is configured as SBFD symbols with uplink subbands, wherein the CSI report includes a first CSI feedback assumption associated with the UE full-duplex mode and a second CSI feedback assumption associated with the UE half-duplex mode; and transmit configuration information in conjunction with the CSI report, the configuration information indicating a first set of transmission parameters for the first set of symbols associated with the UE full-duplex mode and a second set of transmission parameters for the second set of symbols associated with the UE half-duplex mode. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0071] As indicated above, Figure 1 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 1 The examples described are different.

[0072] Figure 2 This is a diagram illustrating an example of communication between a network node 110 and a UE 120 in a wireless network according to the present disclosure.

[0073] like Figure 2 As shown, network node 110 may include a data source 212, a transmit processor 214, a transmit (TX) MIMO processor 216, a set of modems 232 (shown as 232a to 232t, where t≥1), a set of antennas 234 (shown as 234a to 234v, where v≥1), a MIMO detector 236, a receive processor 238, a data sink 239, a controller / processor 240, a memory 242, a communication unit 244, a scheduler 246, and / or a communication manager 150, etc. In some configurations, one or a combination of antennas 234, modems 232, MIMO detectors 236, receive processors 238, transmit processors 214, and / or TX MIMO processors 216 may be included in the transceiver of network node 110. The transceiver may be under the control of and used by one or more processors (such as controller / processor 240), and in some respects, may perform aspects of the methods, procedures and / or operations described herein in conjunction with processor-readable code stored in memory 242. In some respects, network node 110 may include one or more interfaces, communication components and / or other components that facilitate communication with UE 120 or another network node.

[0074] The terms “processor,” “controller,” or “controller / processor” can refer to one or more controllers and / or one or more processors. For example, references to “a / the processor,” “a / the controller / processor,” etc. (in the singular) should be understood as referring to a combination of… Figure 2 The processor described refers to any one or more processors, such as a single processor or a combination of multiple different processors. The reference to "one or more processors" should be understood as a combination of references. Figure 2 Any one or more processors described herein. For example, one or more processors of network node 110 may include transmit processor 214, TX MIMO processor 216, MIMO detector 236, receive processor 238, and / or controller / processor 240. Similarly, one or more processors of UE 120 may include MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, and / or controller / processor 280.

[0075] In some aspects, a single processor can perform all operations described as being performed by one or more processors. In some aspects, a first set of one or more processors can perform a first operation described as being performed by that one or more processors, and a second set of one or more processors can perform a second operation described as being performed by that one or more processors. The processors in the first set and the processors in the second set can be the same set of processors or can be different sets of processors. The reference to "one or more memories" should be understood to refer to any one or more memories of the corresponding device, such as combined... Figure 2 The memory described. For example, an operation described as being performed by one or more memories can be performed by the same subset of the one or more memories or by different subsets of the one or more memories.

[0076] For downlink communication from network node 110 to UE 120, transmitting processor 214 may receive data (“downlink data”) intended for use by UE 120 (or a set of UEs including UE 120) from data source 212 (such as a data pipeline or data queue). In some examples, transmitting processor 214 may select one or more MCSs for UE 120 based on one or more Channel Quality Indicators (CQIs) received from UE 120. Network node 110 may process the data (e.g., including encoding the data) according to the MCS selected for UE 120 for transmission to UE 120 on the downlink, thereby generating data symbols. Transmitting processor 214 may process system information (e.g., semi-static resource partitioning information (SRPI)) and / or control information (e.g., CQI requests, grants, and / or upper-layer signaling) and provide overhead symbols and / or control symbols. The transmitting processor 214 can generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS), demodulation reference signals (DMRS), or CSI reference signals (CSI-RS)) and / or synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)).

[0077] The TX MIMO processor 216 can perform space processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols where applicable, and can output a set of symbol streams (e.g., TA set of output symbol streams is provided to modem 232. For example, each output symbol stream may be provided to a corresponding modulator component (shown as MOD) of modem 232. Each modem 232 may use the corresponding modulator component to process (e.g., modulate) the corresponding output symbol stream (e.g., for orthogonal frequency division multiplexing (OFDM)) to obtain an output sample stream. Each modem 232 may further use the corresponding modulator component to process (e.g., convert to analog, amplify, filter, and / or up-convert) the output sample stream to obtain a time-domain downlink signal. Modems 232a to 232t may transmit the set of downlink signals (e.g., [missing information]) together via a set of corresponding antennas 234. T (One downlink signal).

[0078] Downlink signals may include DCI communication, MAC control element (MAC-CE) communication, RRC communication, downlink reference signals, or another type of downlink communication. Downlink signals may be transmitted on the PDCCH, PDSCH, and / or another downlink channel. Downlink signals may carry one or more transport blocks (TBs) of data. A TB may be a data unit transmitted via the air interface in the wireless communication network 100. A data stream (e.g., from data source 212) may be encoded into multiple TBs for transmission via the air interface. The number of TBs used to carry data associated with a particular data stream may be associated with a TB size shared by multiple TBs. The TB size may be based on the radio channel conditions of the air interface, the MCS used to encode the data, downlink resources allocated for transmitting data, and / or other parameters, or otherwise associated with them. Generally, a larger TB size allows for a larger amount of data to be transmitted in a single transmission, reducing signaling overhead. However, a larger TB size may be more prone to transmission and / or reception errors than a smaller TB size, but such errors can be mitigated through more robust error correction techniques.

[0079] For uplink communication from UE 120 to network node 110, the uplink signal from UE 120 may be received by antenna 234, processed by modem 232 (e.g., demodulator component of modem 232, shown as DEMOD), detected where applicable by MIMO detector 236 (e.g., receive (Rx) MIMO processor), and / or further processed by receive processor 238 to obtain decoded data and / or control information. Receive processor 238 may provide the decoded data to data sink 239 (which may be a data pipeline, data queue, and / or another type of data sink) and provide the decoded control information to processors such as controller / processor 240.

[0080] Network node 110 may use scheduler 246 to schedule one or more UEs 120 for downlink or uplink communication. In some aspects, scheduler 246 may use DCI to dynamically schedule DL transmissions to and / or UL transmissions from UE 120. In some examples, scheduler 246 may allocate repetitive time-domain and / or frequency-domain resources that UE 120 may use for transmitting and / or receiving communication with RRC configuration (e.g., semi-static configuration), for example, to perform semi-persistent scheduling (SPS) or to configure configuration grant (CG) for UE 120.

[0081] One or more of the following may be included in the RF chain of network node 110: transmit processor 214, TX MIMO processor 216, modem 232, antenna 234, MIMO detector 236, receive processor 238, and / or controller / processor 240. The RF chain may include one or more filters, mixers, oscillators, amplifiers, analog-to-digital converters (ADCs), and / or other devices for converting analog signals (such as those used for transmission or reception via an air interface) to digital signals (such as those used for processing by one or more processors of network node 110). In some aspects, the RF chain may be a transceiver of network node 110, or may be included in such a transceiver.

[0082] In some examples, network node 110 may use communication unit 244 to communicate with the core network and / or other network nodes. Communication unit 244 may support wired and / or wireless communication protocols and / or connections, such as Ethernet, fiber optic, Common Public Radio Interface (CPRI), and / or wired or wireless backhaul, etc. Network node 110 may use communication unit 244 to send and / or receive data associated with UE 120, or to execute network control signaling, etc. Communication unit 244 may include transceivers and / or interfaces, such as network interfaces.

[0083] UE 120 may include a collection of antennas 252 (shown as antennas 252a to 252r, where r ≥ 1), a collection of modems 254 (shown as modems 254a to 254u, where u ≥ 1), a MIMO detector 256, a receive processor 258, a data sink 260, a data source 262, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, a memory 282, and / or a communication manager 140, etc. One or more components of UE 120 may be included in housing 284. In some aspects, one or a combination of antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, or TX MIMO processor 266 may be included in a transceiver included in UE 120. The transceiver may be under the control of and used by one or more processors (such as controller / processor 280), and in some respects, may perform aspects of the methods, procedures, or operations described herein in conjunction with processor-readable code stored in memory 282. In some respects, UE 120 may include another interface, another communication component, and / or another component that facilitates communication with network node 110 and / or another UE 120.

[0084] For downlink communication from network node 110 to UE 120, the set of antennas 252 can receive downlink communication or signals from network node 110, and can receive the set of downlink signals (e.g., R Each received signal is provided to a set of modems 254. For example, each received signal may be provided to a corresponding demodulator component (shown as DEMOD) of modem 254. Each modem 254 may use the corresponding demodulator component to condition (e.g., filter, amplify, down-convert, and / or digitize) the received signal to obtain an input sample. Each modem 254 may use the corresponding demodulator component to further demodulate or process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 may obtain the received symbols from the set of modems 254, may perform MIMO detection on the received symbols where applicable, and may provide the detected symbols. Receiver processor 258 may process (e.g., decode) the detected symbols, may provide the decoded data for UE 120 to data sink 260 (which may include data pipelines, data queues, and / or applications executed on UE 120), and may provide the decoded control information and system information to controller / processor 280.

[0085] For uplink communication from UE 120 to network node 110, the transmitting processor 264 may receive and process data (“uplink data”) from data source 262 (such as data pipelines, data queues, and / or applications running on UE 120) and control information from controller / processor 280. The control information may include one or more parameters, feedback, one or more signal measurements, and / or other types of control information. In some aspects, the receiving processor 258 and / or controller / processor 280 may determine one or more parameters related to the transmission of uplink communication for received signals (such as those received from network node 110 or another UE). One or more parameters may include a Reference Signal Received Power (RSRP) parameter, a Received Signal Strength Indicator (RSSI) parameter, a Reference Signal Received Quality (RSRQ) parameter, a Channel Quality Indicator (CQI) parameter, or a Transmit Power Control (TPC) parameter, etc. The control information may include indications of RSRP, RSSI, RSRQ, CQI, TPC, and / or another parameter. Control information can facilitate parameter selection and / or scheduling for UE 120 by network node 110.

[0086] Transmit processor 264 can generate reference symbols for one or more reference signals, such as uplink DMRS, uplink SRS, and / or another type of reference signal. Symbols from transmit processor 264 may be pre-decoded by TX MIMO processor 266 where applicable, and further processed by an assembly of modems 254 (e.g., for DFT-s-OFDM or CP-OFDM). TX MIMO processor 266 can (where applicable) perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, and can provide an output symbol stream set (e.g., ...) to the assembly of modems 254. U Each output symbol stream may be provided to a corresponding modulator component (shown as MOD) of modem 254. Each modem 254 may use the corresponding modulator component to process (e.g., modulate) the corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 254 may further use the corresponding modulator component to process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sample stream to obtain an uplink signal.

[0087] Modems 254a to 254u can transmit uplink signal sets (e.g., via a set of corresponding antennas 252) R One uplink signal or UUplink signals may include UCI communication, MAC-CE communication, RRC communication, or another type of uplink communication. Uplink signals may be transmitted on PUSCH, PUCCH, and / or another type of uplink channel. Uplink signals may carry one or more TBs of data. Sidelink data and control transmission (i.e., transmission directly between two or more UEs 120) may typically use techniques similar to those described for uplink data and control transmission, and may use sidelink-specific channels such as the Physical Sidelink Shared Channel (PSSCH), Physical Sidelink Control Channel (PSCCH), and / or Physical Sidelink Feedback Channel (PSFCH).

[0088] One or more antennas in the set of antennas 252 or the set of antennas 234 may include one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, etc., or may be included in one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, or with one or more transmitting or receiving components (such as...) Figure 2 An antenna module is a combination of one or more antenna elements coupled to one or more components. As used herein, "antenna" can mean one or more antennas, one or more antenna panels, one or more antenna groups, one or more collections of antenna elements, or one or more antenna arrays. "Antenna panel" can mean a group of antennas (such as antenna elements) arranged in an array or panel that can facilitate beamforming by manipulating the parameters of that group of antennas. "Antenna module" can mean a circuit that includes one or more antennas, and may also include one or more other components (such as filters, amplifiers, or processors) associated with integrating the antenna module into a wireless communication device.

[0089] In some examples, each antenna element of antenna 234 or antenna 252 may include one or more sub-elements for radiating or receiving radio frequency signals. For example, a single antenna element may include a first sub-element cross-polarized with a second sub-element that can be used to independently transmit the cross-polarized signal. Antenna elements may include patch antennas, dipole antennas, and / or other types of antennas arranged in a linear pattern, a two-dimensional pattern, or another pattern. The spacing between antenna elements can allow signals with a desired wavelength transmitted individually by the antenna elements to interact or interfere (e.g., to form a desired beam) in various directions. For example, given a desired wavelength or frequency range, the spacing may provide a quarter wavelength, half a wavelength, or another fraction of the wavelength between adjacent antenna elements to allow desired constructive and destructive interference modes of signals transmitted by individual antenna elements within that desired range.

[0090] The amplitude and / or phase of signals transmitted via antenna elements and / or sub-elements can be modulated and (e.g., by manipulating phase shifts, phase offsets, and / or amplitudes) shifted relative to each other to generate one or more beams; this is known as beamforming. The term "beam" can refer to the directional transmission of a wireless signal toward a receiving device or otherwise in a desired direction. "Beam" can also generally refer to the direction associated with such directional signal transmission, the set of directional resources associated with the signal transmission (e.g., angle of arrival, horizontal direction, and / or vertical direction), and / or a set of parameters indicating one or more aspects of the directional signal, the direction associated with the signal, and / or the set of directional resources associated with the signal. In some implementations, antenna elements can be individually selected or deselected for the directional transmission of a signal (or multiple signals) by controlling the amplitude of one or more corresponding amplifiers and / or the phase of the signal to form one or more beams. The shape of the beam (such as amplitude, width, and / or the presence of sidelobes) and / or the direction of the beam (such as the angle of the beam relative to the surface of the antenna array) can be dynamically controlled by modifying the phase shifts, phase offsets, and / or amplitudes of multiple signals relative to each other.

[0091] Different UEs 120 or network nodes 110 may include different numbers of antenna elements. For example, UE 120 may include a single antenna element, two antenna elements, four antenna elements, eight antenna elements, or different numbers of antenna elements. As another example, network node 110 may include eight antenna elements, 24 antenna elements, 64 antenna elements, 128 antenna elements, or different numbers of antenna elements. Generally speaking, a larger number of antenna elements provides increased control over the parameters used for beamforming compared to a smaller number of antenna elements, while a smaller number of antenna elements may be less complex to implement and can use less power. Multiple antenna elements can support multi-layer transmission, in which the same time and frequency resources are used to utilize spatial multiplexing to transmit a first layer of communication (which may include a first data stream) and a second layer of communication (which may include a second data stream).

[0092] Beamforming can be used for communication between a UE and a network node, such as for millimeter-wave communication. In this case, the network node can provide the UE with a Transmit Configuration Indicator (TCI) state configuration, which indicates the beam that the UE can use, for example, to receive the Physical Downlink Shared Channel (PDSCH). The TCI state indicates the spatial parameters used for communication. For example, the TCI state for communication can identify the source signal (such as a synchronization signal block, channel state information reference signal, etc.) and the spatial parameters to be derived from the source signal for the purpose of transmitting or receiving communication. For example, the TCI state can indicate the Quasi-Co-location (QCL) type. The QCL type can indicate one or more spatial parameters to be derived from the source signal. The source signal can be referred to as the QCL source. The network node can indicate the active TCI state to the UE, which the UE can use to select the beam for receiving the PDSCH.

[0093] Beam indication can be or includes TCI status information elements, beam identifier (ID), spatial relationship information, TCI status ID, closed-loop index, panel ID, TRP ID, and / or sounding reference signal (SRS) set ID, etc. TCI status information elements (referred to herein as TCI status) can indicate information associated with the beam, such as a downlink beam. For example, a TCI status information element can indicate a TCI status identifier (e.g., tci-StateID ), QCL type (e.g., qcl-Type1 , qcl-Type2 , qcl-TypeA , qcl-TypeB , qcl-TypeC , qcl-TypeD etc.), community signage (e.g., ServCellIndex ), bandwidth identifier ( bwp-Id), reference signal identifiers (such as CSI-RS (e.g., NZP-CSI-RS-ResourceId , SSB-Index Spatial relationship information can similarly indicate information associated with the uplink beam.

[0094] Beam indication can be a combined or separate downlink (DL) / uplink (UL) beam indication within a unified TCI framework. In some cases, the network may use at least UE-specific (unicast) downlink control information (DCI) to indicate a combined or separate DL / UL beam indication from an active TCI state, thereby supporting Layer 1 (L1) based beam indication. In some cases, existing DCI formats 1_1 and / or 1_2 may be reused for beam indication. The network may include support mechanisms for UE confirmation of successful decoding of the beam indication. For example, acknowledgment / negation acknowledgment (ACK / NACK) of a PDSCH scheduled via a DCI carrying the beam indication may also be used as an ACK for the DCI.

[0095] Beam indication can be provided for carrier aggregation (CA) scenarios. Within a unified TCI framework, the network can support public TCI state ID updates and activations to provide public QCL information and / or one or more public UL transmit spatial filters across a set of configured component carriers (CCs). This type of beam indication can be applied to in-band CA as well as joint DL / UL beam indication and individual DL / UL beam indication. The public TCI state ID can refer to a reference signal (RS) determined based on the TCI state indicated by the public TCI state ID, used to provide QCL type D indication and to determine the UL transmit spatial filters across that set of configured CCs.

[0096] Although Figure 2 The boxes in the diagram are illustrated as different components, but the functions described above with respect to these boxes may be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by or under the control of controller / processor 280.

[0097] Figure 3This is an illustration of an example decomposed base station architecture 300 according to the present disclosure. One or more components of the example decomposed base station architecture 300 may be, may include, or may be included in one or more network nodes (such as one or more network nodes 110). The decomposed base station architecture 300 may include a CU 310, which may communicate directly with the core network 320 via a backhaul link, or may communicate indirectly with the core network 320 via one or more decomposed control units (such as non-RT RIC 350 and / or near-RT RIC 370 associated with a Service Management and Orchestration (SMO) framework 360 (e.g., via an E2 link)). The CU 310 may communicate with one or more DU 330s via a corresponding midhaul link (such as via an F1 interface). Each DU 330 may communicate with one or more RU 340s via a corresponding fronthaul link. Each RU 340 may communicate with one or more UE 120s via a corresponding RF access link. In some deployments, a UE 120 may be served simultaneously by multiple RU 340s.

[0098] Each component in the decomposed base station architecture 300 (including CU 310, DU 330, RU 340, near-RT RIC 370, non-RT RIC 350, and SMO frame 360) may include one or more interfaces or be coupled to one or more interfaces for receiving or transmitting signals, such as data or information, via wired or wireless transmission media.

[0099] In some respects, the CU 310 can be logically divided into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units can communicate bidirectionally with the CU-CP units via an interface such as an E1 interface. The CU 310 can be deployed to communicate with one or more DU 330s for network control and signaling, as needed. Each DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RU 340s. For example, the DU 330 may host various layers, such as the RLC layer, MAC layer, or one or more PHY layers (such as one or more high PHY layers or one or more low PHY layers). Each layer (which may also be referred to as a module) can be implemented using an interface for signaling to other layers (and modules) hosted by the DU 330, or for signaling to control functions hosted by the CU 310. Each RU 340 may implement lower-layer functionality. In some respects, the real-time and non-real-time aspects of communication with the control plane and user plane of the RU 340 can be controlled by the corresponding DU 330.

[0100] The SMO framework 360 supports RAN deployment and provisioning for both non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 360 supports the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via operation and maintenance interfaces such as the O1 interface. For virtualized network elements, the SMO framework 360 can interact with cloud computing platforms such as the Open Cloud (O-Cloud) platform 390 to perform network element lifecycle management (such as instantiating virtualized network elements) via cloud computing platform interfaces such as the O2 interface. Virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 350, and / or near-RT RIC 370. In some aspects, the SMO framework 360 can communicate with hardware aspects of the 4G RAN, 5G NR RAN, and / or 6G RAN (such as the Open eNB (O-eNB) 380) via the O1 interface. Additionally or alternatively, the SMO framework 360 can communicate directly with each of one or more RUs 340 via the corresponding O1 interface. In some deployments, this configuration enables each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

[0101] The non-RT RIC 350 may include or implement logical functions that enable non-real-time control and optimization of RAN elements and resources, including artificial intelligence / machine learning (AI / ML) workflows for model training and updates, and / or policy-based guidance of applications and / or features in the near-RT RIC 370. The non-RT RIC 350 may be coupled to or communicate with the near-RT RIC 370, such as via an A1 interface. The near-RT RIC 370 may include or implement logical functions that enable near real-time control and optimization of RAN elements and resources via an interface, such as an E2 interface, through data collection and actions, connecting one or more CU 310s, one or more DU 330s, and / or O-eNBs to the near-RT RIC 370.

[0102] In some respects, to generate AI / ML models to be deployed in the near-RT RIC 370, the non-RT RIC 350 may receive parameters or external enrichment information from an external server. This information can be utilized by the near-RT RIC 370 and may be received from non-network data sources or network functions at the SMO framework 360 or the non-RT RIC 350. In some examples, the non-RT RIC 350 or near-RT RIC 370 may modulate RAN behavior or performance. For example, the non-RT RIC 350 may monitor long-term trends and patterns in performance and may employ AI / ML models to perform corrective actions via the SMO framework 360 (such as reconfiguration via the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0105] In some aspects, the UE (e.g., UE 120) includes components for transmitting UE capability information associated with an SBFD configuration, in which a set of flexible symbols is configured as SBFD symbols with subbands, wherein the UE capability information includes UE capability indications associated with switching between UE full-duplex mode and UE half-duplex mode; and / or components for communicating in conjunction with the UE capability indications.

[0106] In some aspects, the UE (e.g., UE 120) includes components for transmitting a CSI report associated with an SBFD configuration, in which a set of flexible symbols is configured as SBFD symbols with uplink subbands, wherein the CSI report includes a first CSI feedback assumption associated with the UE's full-duplex mode and a second CSI feedback assumption associated with the UE's half-duplex mode; and / or components for receiving configuration information in conjunction with the CSI report, the configuration information indicating a first set of transmission parameters for the first set of symbols associated with the UE's full-duplex mode and a second set of transmission parameters for the second set of symbols associated with the UE's half-duplex mode. Components for the UE to perform the operations described herein may include, for example, one or more of the following: a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0107] In some aspects, a network node (e.g., network node 110) includes components for receiving UE capability information associated with an SBFD configuration, in which a set of flexible symbols is configured as SBFD symbols with subbands, wherein the UE capability information includes UE capability indications associated with handover between UE full-duplex and UE half-duplex modes; and / or components for communicating in conjunction with the UE capability indications. Components for the network node to perform the operations described herein may include, for example, one or more of the following: a communication manager 150, a transmit processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0108] In some aspects, a network node (e.g., network node 110) includes components for receiving CSI reports associated with an SBFD configuration, in which a set of flexible symbols is configured as SBFD symbols with uplink subbands, wherein the CSI report includes a first CSI feedback hypothesis associated with a UE full-duplex mode and a second CSI feedback hypothesis associated with a UE half-duplex mode; and / or components for combining the CSI report to transmit configuration information indicating a first set of transmission parameters for a first set of symbols associated with a UE full-duplex mode and a second set of transmission parameters for a second set of symbols associated with a UE half-duplex mode. Components for the network node to perform the operations described herein may include, for example, one or more of the following: a communication manager 150, a transmit processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0109] Figures 4A to 4C These are illustrations of examples 400, 410, and 420 of full-duplex (FD) communication according to this disclosure. Figure 4A Example 400 includes UE1 402 and two network nodes (e.g., Transmit / Receive Points (TRPs)) 404-1 and 404-2, where UE1 402 is transmitting UL transmissions to network node 404-1 and receiving DL transmissions from network node 404-2. Figure 4A In Example 400, FD is enabled for UE1 402 but not for network nodes 404-1 and 404-2. Figure 4B Example 410 includes two UEs (shown as UE1 402-1 and UE2 402-2) and a network node 404, where UE1 402-1 is receiving DL transmissions from network node 404, and UE2 402-2 is sending UL transmissions to network node 404. Figure 4B In Example 410, FD is enabled for network node 404 but not for UE1 402-1 and UE2 402-2. Figure 4C Example 420 includes UE1 402 and network node 404, where UE1 402 is receiving DL transmissions from network node 404, and UE1 402 is sending UL transmissions to network node 404. Figure 4C In Example 420, FD is enabled for both UE1 402 and network node 404.

[0110] As indicated above, Figures 4A to 4C This is provided as one or more examples. Other examples may be found with reference to... Figures 4A to 4C The examples described are different.

[0111] Figure 5 These are illustrations of examples 500, 505, and 510 of FD communication in a wireless network according to this disclosure. For example... Figure 5 As shown, Examples 500 and 505 illustrate examples of in-band full-duplex (IBFD) communication (which may also be referred to herein as “full-duplex” (FD) communication). In FD, the UE can send uplink communication to and receive downlink communication from the network node on the same time and frequency resources. As shown in Example 500, in a first example of FD (referred to as “fully overlapping FD”), the time and frequency resources used for uplink communication can fully overlap with those used for downlink communication. As shown in Example 505, in a second example of FD (referred to as “partially overlapping FD”), the time and frequency resources used for uplink communication can partially overlap with those used for downlink communication.

[0112] like Figure 5 As further illustrated, Example 510 shows an example of SBFD communication, which can also be referred to as "Subband Frequency Division Duplex (SBFDD)" or "Flexible Duplex." In SBFD, a UE can send uplink communication to a network node and receive downlink communication from a network node on the same time resources but on different frequency resources. For example, different frequency resources can be subbands of a band such as a Time Division Duplex (TDD) band. In this case, the frequency resources used for downlink communication can be separated from the frequency resources used for uplink communication in the frequency domain by guard bands.

[0113] As indicated above, Figure 5 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 5 The examples described are different.

[0114] Figure 6A and Figure 6B This is a diagram illustrating an example of an SBFD configuration associated with this disclosure.

[0115] Figure 6A This is a diagram illustrating example 600 activated according to the SBFD of this disclosure. For example... Figure 6AAs shown, Example 600 includes a first configuration 602. In some aspects, the first configuration 602 may indicate a first time slot format mode (sometimes referred to as TDD mode) associated with a half-duplex mode or FD mode. Each time slot and / or portions thereof (e.g., symbols) may be scheduled and / or configured for uplink (“UL”) communication, downlink (“DL”) communication, or flexible (“F”). Flexible time slots may be used for either uplink or downlink communication. Resources configured and / or scheduled for uplink communication are described herein as having an uplink (U) format. Resources configured and / or scheduled for downlink communication are described herein as having a downlink (D) format. Resources configured and / or scheduled to include only flexible resources are described herein as having a flexible (F) format. All symbols within each time slot may be similarly assigned (e.g., all “UL”, all “DL”, or all “F”), or the time slot may otherwise include multiple symbol assignment types. The first time slot format pattern may include a number of downlink time slots (e.g., three downlink time slots 604a, 604b, and 604c as shown in the figure), a number of flexible time slots (not shown), and / or a number of uplink time slots (e.g., one uplink time slot 606 as shown in the figure). The first time slot format pattern may repeat over time. In some aspects, network node 110 may use one or more time slot format indicators to indicate the first time slot format pattern to UE 120. The time slot format indicator used for a time slot may indicate whether the time slot is an uplink time slot, a downlink time slot, or a flexible time slot, etc.

[0116] Network node 110 may (e.g., using indications such as RRC messages, MAC control element MAC-CE, or downlink control information (DCI)) instruct UE 120 to switch from first configuration 602 to second configuration 608. Alternatively, UE 120 may indicate to network node 110 that UE 120 is switching from first configuration 602 to second configuration 608. Second configuration 608 may indicate a second time slot format pattern that repeats over time, similar to the first time slot format pattern. In any of the aspects described above, UE 120 may switch from first configuration 602 to second configuration 608 for a period of time (e.g., a certain number of symbols and / or a certain amount of time (e.g., in ms)) based at least in part on an indication received from network node 110 (e.g., before switching back to first configuration 602). During this period, UE 120 may communicate using the second time slot format pattern and may then revert to using the first time slot format pattern after the end of the period. The time period may be indicated by network node 110 (e.g., in an instruction to switch from first configuration 602 to second configuration 608, as described above) and / or at least partially based on programmed and / or otherwise pre-configured rules. For example, the rule may be at least partially based on a table (e.g., defined in a 3GPP specification and / or another wireless communication standard) that associates different subcarrier spacings (SCS) and / or sets of parameters (e.g., represented by µ and associated with corresponding SCS) with corresponding time periods for switching configurations.

[0117] In Example 600, the second timeslot format mode includes a downlink timeslot 610, an uplink timeslot 618, and two SBFD timeslots instead of the downlink timeslot in the first timeslot format mode. In Example 600, each SBFD timeslot includes a portion of the timeslot for the downlink (e.g., a portion or subband of a frequency allocated for use by network node 110 and UE 120) (e.g., portions of timeslots 612a, 612b, 612c, and 612d as shown) and a portion of the timeslot for the uplink (e.g., portions of timeslots 614a and 614b as shown). Therefore, UE 120 can use the second timeslot format mode to operate and transmit uplink communication in an earlier timeslot (e.g., the second timeslot in the sequence, shown as portion of UL timeslot 614a) compared to using the first timeslot format mode (e.g., the fourth timeslot in the sequence). Other examples may include additional or alternative variations. For example, the second configuration 608 may indicate an SBFD slot instead of an uplink slot (e.g., UL slot 606) in the first configuration 602. In another example, the second configuration 608 may indicate either a downlink slot or an uplink slot instead of an SBFD slot in the first configuration 602. Figure 6A(Not shown in the image). In yet another example, the second configuration 608 may indicate a downlink timeslot or an uplink timeslot to replace the uplink timeslot or downlink timeslot in the first configuration 602, respectively. "SBFD timeslot" refers to a timeslot in which the SBFD format is used.

[0118] The SBFD format may include a time slot format that supports FD communication (e.g., for both uplink and downlink communication), wherein one or more frequencies for the uplink portion of the time slot are separated from one or more frequencies for the downlink portion of the time slot by guard bands. In some examples, the SBFD format may include a single uplink portion and a single downlink portion separated by guard bands. In some examples, the SBFD format may include multiple downlink portions and a single uplink portion, which is separated from the multiple downlink portions by corresponding guard bands (e.g., such as...). Figure 6A (As shown). In some examples, the SBFD format may include multiple uplink portions and a single downlink portion, which is separated from the multiple uplink portions by corresponding guard bands. In some examples, the SBFD format may include multiple uplink portions and multiple downlink portions, wherein each uplink portion is separated from the downlink portion by a guard band. In some examples, operating using SBFD mode may include activating or using FD mode in one or more time slots, at least in part, based on one or more time slots having the SBFD format. A time slot may support SBFD mode if uplink bandwidth portions (BWP) and downlink BWPs are permitted to be active or simultaneously in a time slot in an SBFD manner (e.g., using guard band separation).

[0119] By switching from the first configuration 602 to the second configuration 608, network node 110 and UE 120 may experience increased communication quality and / or reliability. For example, network node 110 and UE 120 may experience increased throughput (e.g., using FD mode), reduced latency (e.g., UE 120 may be able to use the second configuration 608 instead of the first configuration 602 to send uplink and / or receive downlink communication faster), and increased network resource utilization (e.g., by using both downlink BWP and uplink BWP simultaneously instead of using only downlink BWP or uplink BWP).

[0120] Figure 6B This is a diagram illustrating example 620 of SBFD operation in flexible notation according to this disclosure.

[0121] As indicated by reference numeral 622 in the attached figure, resources (e.g., time slots and / or symbols) 624 can be configured semi-statically as flexible, and thus can be reconfigured later for uplink or downlink communication. In some aspects, common configuration parameters (e.g., ...) are sent to all UEs in the cell. tdd-UL-DL-ConfigurationCommon (or similar common configuration parameters) define a semi-static slot and / or symbol structure 626, including specifying certain slots or symbols for uplink communication, downlink communication, or specifying them flexibly for uplink or downlink communication. For example, common configuration parameters can semi-statically configure slots and symbols with an initial configuration. Specific configuration parameters (e.g., ...) that can be sent to a specific UE via a slot format indicator (SFI) can also be used. tdd-UL-DL-ConfigurationDedicated This can then be used to reconfigure flexible time slots and symbols as uplink or downlink time slots and symbols to perform SBFD configuration 628. In some cases, for remaining flexible time slots or symbols (e.g., those still configured as flexible time slots or symbols after reconfiguration due to dedicated configuration parameters), the UE can monitor the Physical Downlink Control Channel (PDCCH) information and determine, at least in part, whether the flexible time slot or symbol should be configured as an uplink time slot or symbol or a downlink time slot or symbol based on the uplink and / or downlink resource allocation indicated by the PDCCH information. In some cases, flexible time slots or symbols can be dynamically changed by the network node via DCI messages or similar messages (which may be referred to as UE-specific configurations).

[0122] Resources (e.g., time slots and / or symbols, such as downlink or flexible time slots and / or symbols) can be configured to have an SBFD format. Resources with an SBFD format include one or more SBFD symbols. An SBFD symbol is a symbol having one or more subbands (referred to herein as SBFD subbands) that a network node (such as a gNB) can use or will use to perform SBFD operations. For SBFD operations within a TDD carrier, an SBFD subband may include a single resource block or a set of consecutive resource blocks for the same transmission direction. In some aspects, for SBFD operations within a TDD carrier, an SBFD subband consists of a single resource block or a set of consecutive resource blocks for the same transmission direction. In some aspects, an "SBFD symbol" is defined as a symbol having a subband that a gNB will use for SBFD operations. In some aspects, for SBFD operations within a TDD carrier, an SBFD subband consists of a single resource block (RB) or a set of consecutive RBs for the same transmission direction.

[0123] SBFD resources (i.e., resources with SBFD format) may include one or more symbols and / or one or more time slots. As mentioned above, SBFD resources may include at least one uplink subband (i.e., a subband for uplink communication of the UE) and at least one downlink subband (i.e., a subband for downlink communication of the UE). As indicated by reference numeral 630, SBFD configuration 628 may include two non-contiguous downlink subbands 632 and 634, and one uplink subband 636. The two downlink subbands 632 and 634 may be used by a single UE, or may be used by different UEs (e.g., a first UE uses a first downlink subband 632, and a second UE uses a second downlink subband 634). As mentioned above, a subband may include one or more contiguous resource blocks associated with the transmission direction. Example 620 may exemplify a symbol having SBFD format (e.g., a symbol having a set of resource blocks including at least one downlink subband and a set of resource blocks including at least one uplink subband), a time slot having SBFD format (e.g., a time slot having at least one downlink subband and at least one uplink subband), or another time resource having SBFD format.

[0124] In some respects, for TDD-UL-DL-ConfigCommon The symbol is configured for flexible SBFD operation. For SBFD-aware UEs, uplink transmission within the uplink subband is permitted within this symbol. From the network's perspective, resource blocks (RBs) outside the uplink subband can be used as either uplink or downlink within this symbol (excluding guard bands, if used), and all these RBs can be transmitted in the same direction. In some cases, uplink transmission occurs within the active uplink BWP within this symbol, and downlink reception occurs within the active downlink BWP. For all RBs outside the uplink subband, the UE may not be able to use a single RB for both downlink and uplink simultaneously.

[0125] As indicated above, Figure 6A and Figure 6B This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 6A and Figure 6B The examples described are different.

[0126] In some cases, UEs capable of FD and / or SBFD can be configured to communicate with one or more network nodes, cells, and / or TRPs capable of SBFD to further enhance system capacity, UL coverage, and reduce latency. In other cases, an SBFD UE can communicate with two half-duplex (HD) cells and / or TRPs (e.g., some cells with low capabilities can still be implemented in HD cell mode). In some cases, two or more communication modes can be implemented in different time periods. The ability to switch between communication modes can be useful to promote flexibility and efficiency in resource allocation and power consumption from the perspective of the UE and / or network nodes.

[0127] Figures 7A to 7D This is a diagram illustrating examples of various communication modes according to this disclosure. Figure 7A Example 700 illustrates a first communication mode (“Mode 1”) in which HDUE 702 communicates with network node 704 providing the HD cell. During a period of time, UE 702 may receive communication from or send communication to network node 704. Figure 7B Example 706 illustrates a second communication mode (“Mode 2”) of an SBFD cell in which network node 704 provides communication with two HD UEs 702 and 708. During a time period, UE 702 can simultaneously send communications to network node 704 and receive communications from network node 704 at the same time as UE 708 sends communications to network node 704.

[0128] Figure 7C Example 710 illustrates a third communication mode (“Mode 3”) in which the SBFD UE 702 communicates with the network node 704 providing the SBFD cell. During a period of time, the UE 702 may simultaneously send (e.g., via the UL subband) communication to the network node 704 and receive (e.g., via the DL subband) communication from the network node 704. Figure 7D Example 712 illustrates a fourth communication mode (“Mode 4”) in which the SBFD UE 702 communicates with one or more network nodes 704, 714 via two HD cells and / or HD TRPs, respectively. During a time period, the UE 702 may receive communication from a first TRP 704 (and / or via a first cell) and send communication to a second TRP 714 (and / or via a second cell). In some cases, a fifth communication mode (“Mode 5”) may be implemented, in which the FD UE communicates with one or more TRPs and / or via one or more cells. The FD UE may be configured for partially overlapping FD and / or fully overlapping FD.

[0129] For SBFD symbols configured on flexible symbols, an alternative could be to configure the symbol as F / U / F. In some cases, RBs outside the uplink subband can be scheduled as D (D / U / D) or as U (U / U / U). In this case, even an F symbol configured with an uplink subband as an SBFD symbol can be an SBFD symbol or a U symbol. For SBFD-capable UEs supporting both FD and HD modes, handover between SBFD UEs and HD UEs may be required on F symbols configured with UL subbands (e.g., UL filters switching between FD and HD symbols). For example, as... Figure 6B As shown, potential switching point 638 may exist between F and U symbols outside the subband. Other switching points 640 may exist between symbols within the subband.

[0130] Some aspects of the technologies and apparatus described herein may include defining UE capabilities related to handover between FD and HD symbols. In some aspects, the network may configure and / or schedule resources based on UE capabilities, which facilitates support for different communication modes at the UE. In some aspects, UE capabilities associated with handover between HD and FD communication may be indicated based on classification. In some aspects, different UE capabilities may be defined for different types of symbols. For example, a UE may have a first set of capabilities associated with F symbols and a second set of capabilities associated with semi-statically configured SBFD symbols and non-SBFD symbols. In this way, some aspects facilitate the UE's switching between communication modes over different time periods, thereby enhancing the flexibility of configuring HD and / or FD communication between one or more UEs and one or more network nodes, thus allowing for improved network efficiency in resource allocation and / or improved device efficiency in terms of power consumption.

[0131] In some cases, if an SBFD UE operates in UE SBFD mode in some SBFD symbols / slots and in HD mode in some other SBFD symbols / slots, and the network node is in SBFD mode, the same semi-static time in the SBFD symbols and the same DL / UL subband network node SBFD configuration may not be sufficient to distinguish between the two different UE modes. In some cases, the UE may have different antenna configurations for both modes. For example, in some cases, the UE may use the entire antenna array for HD mode; however, the UE may split the entire antenna array into two separate antenna arrays / panels for UE SBFD mode. For SBFD UE mode, the network node may need to consider system information (SI) conditions to configure the two TCI states for paired DL and UL transmissions for the UE, which may differ from the optimal RSRP TCI state in HD UE mode. For example, in some cases, operating parameters (e.g., UL transmit power, modulation and decoding scheme (MCS), DL beam and / or UL beam, etc.) may differ. The RF components of a network node can be retuned for two different modes (e.g., if an additional UE filter is used for UE SBFD mode (e.g., for SI suppression)). In some cases, UE SBFD may require different subbands, frequency modes, and / or guard bands compared to network node SBF (e.g., handover delay can be used to support this feature). As described above, the UE spatial configuration can differ between UE FD mode and UE HD mode.

[0132] Accordingly, in some aspects, UE capability information may include spatial configuration switching capability indications. In some aspects, based on spatial configuration switching capability indications, network nodes may send spatial configuration switching instructions. In some aspects, spatial configuration switching rules may be indicated by wireless communication standards and thus maintained in one or more memories of the UE. In this way, in some aspects, network nodes can distinguish between UE HD mode and UE FD mode, and thereby reconfigure transmission parameters and / or network node components to communicate with the UE more efficiently and accurately. Therefore, in some aspects, network performance can be positively impacted.

[0133] As indicated above, Figures 7A to 7D This is provided as an example. Other examples are available with reference to [the relevant information]. Figures 7A to 7D The examples described are different.

[0134] Figure 8 This is a diagram illustrating an example 800 associated with a UE capability for switching between FD mode and HD mode according to this disclosure. Figure 8 As shown, UE 802 and network node 804 can communicate with each other. In some aspects, UE 802 may be, resemble, include, or be included in the following: Figures 7A to 7D UE 702 and / or UE 708 as depicted in the text; Figures 4A to 4C UE1 402, UE1 402-1 and / or UE2 402-2 as depicted in the text; and / or Figures 1 to 3 The UE 120 is depicted in the diagram. In some respects, network node 804 may be, resemble, include, or be included in the following: Figures 7A to 7D The TRP 704 and / or TRP 714 depicted in the text; Figures 4A to 4C The TRP 404, TRP 404-1 and / or TRP 404-2 described in the document; Figure 1 and Figure 2 Network node 110 as depicted; and / or Figure 3 One or more components of the decomposed base station architecture 300 described herein.

[0135] As shown by reference numeral 806 in the attached figure, UE 802 can transmit and network node 804 can receive UE capability information. In some aspects, the UE capability information may be associated with an SBFD configuration, in which a set of flexible or downlink symbols is configured as SBFD symbols with uplink (or downlink) subbands. In some aspects, the UE capability information may include a UE capability indication associated with handover between UE full-duplex mode and UE half-duplex mode.

[0136] In some aspects, UE capability information may be associated with two or more communication modes among a plurality of communication modes. The two or more communication modes may include at least one FD mode. This at least one FD mode may include at least one of SBFD mode, partially overlapping FD mode, or fully overlapping FD mode. In some aspects, the two or more communication modes may include a first mode (e.g., mode 1), wherein UE 802 includes an HD UE and network node 804 provides an HD cell. In the first mode, UE 802 may communicate with network node 804 in a communication direction (e.g., uplink or downlink) for a period of time (e.g., a symbol or a time slot). The two or more communication modes may include a second mode (e.g., mode 2), wherein UE 802 may include a first HD UE among a plurality of HD UEs and network node 804 provides an SBFD cell. In the second mode, UE 802 may communicate with network node 804 in a communication direction during that period of time. The two or more communication modes may include a third mode (e.g., mode 3), wherein UE 802 includes an SBFD UE and network node 804 provides an SBFD cell. In the third mode, UE 802 may communicate with network node 804 in two communication directions during the time period. Two or more communication modes may include a fourth mode (e.g., mode 4), where UE 802 may include an SBFDUE and network node 804 may provide a Transmit / Receive Point (TRP) for one or more HD cells. In the fourth mode, UE 802 may communicate in a first communication direction via a cell or TRP during the time period, and in a second communication direction via an additional cell or additional TRP during the time period. Two or more communication modes may include a fifth communication mode (e.g., mode 5), where UE 802 may include a partially overlapping FD UE and / or a fully overlapping FD UE.

[0137] In some aspects, UE capability information may include UE capability indications associated with handover between UE full-duplex mode and UE half-duplex mode. The UE capability indications may include at least one filter switching capability indication indicating a category among a plurality of potential categories associated with UE 802. In some aspects, each of the plurality of potential categories may be associated with a filter capability among a plurality of filter capabilities. A first category among the plurality of potential categories may be associated with a first filter capability among the plurality of filter capabilities, and the first filter capability may indicate that UE 802 supports only fixed wideband filters. Fixed wideband filters may be associated with full-duplex symbols and half-duplex symbols.

[0138] In some aspects, a second category among the multiple potential categories may be associated with a second filter capability among the multiple filter capabilities. The second filter capability may instruct UE 802 to support adaptive uplink filtering only at the boundary between semi-statically configured SBFD time units and non-SBFD time units. The semi-statically configured SBFD time unit may include at least one of a first symbol or a first timeslot, and the non-SBFD time unit may include at least one of a second symbol or a second timeslot. For example, UE 802 may be configured to adapt uplink filtering only between semi-statically configured SBFD and non-SBFD symbol / timeslot boundaries (e.g., between F and U). In this case, for at least one SBFD symbol, additional scheduling offsets may not be required to retune the filter. For example, the UE may communicate without scheduling offsets. In some aspects, additional handover protection periods (which may be provided via scheduling offsets) may be used only between SBFD and non-SBFD symbol types (e.g., between F / D and U).

[0139] In some respects, the third category of the multiple potential categories may be associated with the third filter capability of the multiple filter capabilities, and the third filter capability may include the second filter capability and may indicate that UE 802 supports filter adaptation across flexible or downlink symbols that are semi-statically configured as SBFD symbols. When the uplink bandwidth changes on the SBFD configured on the F symbol (e.g., from U / U / U to D / U / D, or vice versa), UE 802 may require additional scheduling offsets for filter retuning.

[0140] In some aspects, the UE capability indication may include an indication that UE 802 supports dynamic bandwidth switching. In some aspects, the UE may only support the default wideband filter. In some aspects, UE 802 may support uplink filter adaptation. In some aspects, the UE capability indication may indicate that UE 802 cannot support dynamic bandwidth switching. In some aspects, the UE capability indication may indicate that UE 802 supports switching between semi-statically configured SBFD symbols and non-SBFD symbols without a guard period. Filters may include, for example, any type of filter that can be applied to the transmitted or received signals, such as interference filters. Uplink filters can be used for transmissions performed by UE 802. Downlink filters can be used for receptions performed by UE 802. Wideband filters can be applied across the entire frequency band (e.g., SBFD resources), while narrowband filters can be applied to a subset of the frequency band (e.g., a sub-band of SBFD resources, one or more resource blocks).

[0141] In some aspects, the UE capability indication may indicate that UE 802 supports handover between semi-statically configured SBFD symbols and non-SBFD symbols under guard periods. In some aspects, the UE capability indication may include a spatial configuration handover capability indication. In some aspects, UE 802 may receive a spatial configuration handover indication from network node 804 based on the spatial configuration handover capability indication. Receiving the spatial configuration handover indication may include receiving downlink control information (DCI) including the spatial configuration handover indication. In some aspects, the wireless communication standard may indicate spatial configuration handover rules, and therefore the spatial configuration handover rules may be maintained in one or more memories of UE 802 and / or network node 804. Spatial configuration may include, for example, TCI states, QCL parameters, spatial filters, one or more beam parameters, etc.

[0142] In some respects, the spatial configuration handover capability indication may be associated with a protection period used for handover between UE full-duplex mode and UE half-duplex mode. UE capability information may indicate the length of the protection period. The indication of the length of the protection period may be stored in one or more memories of network node 804. In some respects, the length of the protection period may include the maximum of the filter retuning delay value and the spatial configuration handover delay value.

[0143] As shown by reference numeral 808 in the attached figure, UE 802 can send a CSI report, and network node 804 can receive the CLI report. The CSI report can be a periodic CSI report, an aperiodic CSI report, or a semi-persistent CSI report. In some aspects, the CSI report can be associated with an SBFD configuration, in which a set of flexible or downlink symbols is configured as SBFD symbols with uplink subbands. UE full-duplex mode is a mode in which the UE communicates in full-duplex mode (such as SBFD). UE half-duplex mode is a mode in which the UE communicates in half-duplex mode, such as performing only uplink transmission or only downlink reception at a given time.

[0144] In some aspects, a CSI report may include a first CSI feedback assumption associated with the UE's full-duplex mode and a second CSI feedback assumption associated with the UE's half-duplex mode. For example, in a single CSI report, a full-duplex UE may report two assumptions for its CSI feedback: one assumption or set of assumptions for full-duplex mode and one assumption or set of assumptions for half-duplex mode. Assumptions may indicate a set of feedback (e.g., CQI, rank, PMI) corresponding to a specific configuration, mode, or state. In this context, the first assumption may indicate feedback derived assuming the UE is in full-duplex mode, and the second assumption may indicate feedback derived using the UE in half-duplex mode.

[0145] As shown by reference numeral 810 in the attached figure, network node 804 can send configuration information, and UE 802 can receive configuration information. In some aspects, the configuration information can be associated with two or more communication modes. In some aspects, the configuration information can be associated with SBFD configuration, in which a set of flexible or downlink symbols is configured as SBFD symbols within the uplink subband.

[0146] As shown by reference numeral 812, UE 802 and network node 804 can communicate with each other. For example, UE 802 and network node 804 can communicate with each other in conjunction with UE capability indications. In some aspects, communicating in conjunction with UE capability indications may include: communicating based on uplink bandwidth varying between communication direction schemes associated with a set of flexible or downlink symbols configured as SBFD symbols, combined with scheduling offsets associated with filter retuning operations. In some aspects, communicating in conjunction with UE capability indications may include: UE 802 transmitting first communication in the uplink subband of an SBFD symbol in a set of flexible or downlink symbols configured as SBFD symbols, according to a first uplink filter mode. UE 802 may also transmit second communication in full-band uplink symbols according to a second uplink filter mode, and may switch back to the first uplink filter mode based on the completion of transmitting the second communication. For example, UE 802 may autonomously switch to the first uplink filter mode. The first uplink filter mode may include a default filter mode. In some aspects, transitioning to the first uplink filter mode may include sending a default indication to the first uplink filter mode. The default indication may include at least one of the following: an indication stored in one or more memories of the UE 802, an indication included in configuration information received by the UE 802, or an indication included in UE capability information.

[0147] In some aspects, communication in conjunction with UE capability indications may include: transmitting first communication in an uplink subband of an SBFD symbol within a set of flexible or downlink symbols configured as SBFD symbols, according to a first uplink filter mode. UE 802 may transmit second communication in full-band uplink symbols according to a second uplink filter mode, and may maintain the second uplink filter mode based on the completion of transmitting the second communication. For example, the first uplink filter mode may include a latest filter mode. In some aspects, transitioning to the first uplink filter mode may include transitioning to the first uplink filter mode based on a default indication. The default indication may include at least one of the following: an indication stored in one or more memories of UE 802, an indication included in configuration information received by UE 802, or an indication included in UE capability information.

[0148] In some aspects, communicating in conjunction with UE capability indications may include sending uplink transmissions scheduled only within the uplink subband. In other aspects, sending uplink transmissions may include sending uplink transmissions in conjunction with a default narrowband uplink filter.

[0149] As indicated above, Figure 8 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 8 The examples described are different.

[0150] Figure 13 This is a diagram of an example device 1300 for wireless communication according to the present disclosure. Device 1300 may be a UE, or a UE may include device 1300. In some aspects, device 1300 includes a receiving component 1302, a transmitting component 1304, and / or a communication manager 1306 that can communicate with each other (e.g., via one or more buses and / or one or more other components). In some aspects, communication manager 1306 is combined with... Figure 1 The communication manager 140 is described. As shown, the device 1300 can communicate with another device 1308 (such as a UE or a network node (such as a CU, DU, RU or base station)) using the receiving component 1302 and the transmitting component 1304.

[0151] Figure 9 This is a diagram illustrating an example process 900 performed, for example, at a UE or a device of a UE, according to this disclosure.

For example, the UE (e.g., using...) Figure 13 The transmitting component 1304 and / or communication manager 1306 depicted herein can transmit UE capability information associated with an SBFD configuration, in which a set of flexible or downlink symbols is configured as SBFD symbols having at least one uplink subband. The UE capability information may include an indication of UE capability related to at least one of filter switching capability or spatial configuration switching capability, which is associated with switching between UE full-duplex mode and UE half-duplex mode, as described above.
