[0001] This application claims the benefit of U.S. Nonprovisional Patent Application Serial No. 18 / 506,844, entitled “INSTANTANEOUS UE SI MEASUREMENT AND REPORTING”, filed November 10, 2023, the entire contents of which are expressly incorporated herein by reference. Technical Field

[0002] This disclosure relates generally to communication systems, and more specifically to the measurement and reporting of user equipment (UE) self-interference (SI) in wireless communications. Background Technology

[0003] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple access technologies 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.

[0004] These multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different wireless devices to communicate at the city, national, regional, and even global levels. An example telecommunications standard is 5G New Radio (NR). 5G NR is part of the Continuous Evolution of Mobile Broadband (CEM) program issued by the 3rd Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with the Internet of Things (IoT),) and other requirements. 5G NR includes services associated with enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), and ultra-reliable low-latency communications (URLLC). Some aspects of 5G NR can be based on the 4G Long Term Evolution (LTE) standard. Further improvements to 5G NR technology are needed. Furthermore, these improvements can also be applied to other multiple access technologies and telecommunications standards that adopt these technologies. Summary of the Invention

[0037] In wireless communication, Subband Full-Duplex (SBFD) communication enables a device to transmit and receive simultaneously within the same frequency range. As an example, a base station (e.g., a gNB or other type of base station) can serve one or more User Equipments (UEs) simultaneously in both the downlink (DL) and uplink (UL) within a corresponding subband. However, when a base station with SBFD capability configures a UE to transmit in the UL subband and receive in the DL subband within the same time-frequency resources, self-interference (SI) can degrade system performance. The example aspects presented herein provide methods and apparatus for implementing instantaneous SI measurement and reporting by the UE. This method ensures that the UE can adapt its operating mode in real time, switching between half-duplex (HD) and full-duplex (FD) modes to maintain optimal performance.

[0038] Various aspects are involved in wireless communication as a whole. Some aspects more specifically involve instantaneous UE SI measurement and reporting in wireless communication. Some aspects involve different modes of UE operation for resources allocated as SBFD resources. For example, the UE may communicate in half-duplex mode while the base station transmits and receives in SBFD resources. In other examples, the UE may communicate in full-duplex mode in SBFD resources. In some examples, the UE receives SBFD time and frequency configurations based on the SBFD mode to allocate resources for communication with network entities; obtains a UE operating mode for the resources, wherein the UE operating mode is either UEFD mode or UE HD mode; and, based on the UE operating mode, communicates with network entities in the resources allocated to the UE. In some examples, the UE receives time and frequency configurations based on FD operation to allocate resources for communication with network entities. The UE operates in the resources in either UE HD mode or UE FD mode. The UE further responds to the time and frequency configurations to perform SI measurements for the UE and reports SI indications indicating the SI measurements to the network entities.

[0039] 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, enabling different modes of operation, the described techniques allow the UE to interact flexibly with various cell types and configurations to improve resource utilization efficiency. In some examples, by enabling the UE to measure SI and report the results to the network after an operating mode indication, the described techniques allow for rapid adjustment of operating parameters (such as antenna configuration and transmit power) to optimize its performance based on real-time conditions (such as traffic demand or signal interference), thereby ensuring communication reliability and maintaining optimal performance. In some examples, by incorporating SI information into beam management reports or feedback, the described techniques enable the UE to select the most suitable DL and UL beam pairs, thereby enhancing the reliability of FD operation.

[0040] The detailed descriptions following, illustrated with reference to the accompanying drawings, describe various configurations and do not represent the only configurations in which the concepts described herein can be practiced. To provide a thorough understanding of the various concepts, the detailed descriptions include specific details. However, these concepts can be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid obscuring these concepts.

[0041] Various apparatuses and methods are presented with reference to several aspects of a telecommunications system. These apparatuses and methods are described in detail below and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively, “elements”). These elements may be implemented using electronic hardware, computer software, or any combination thereof. 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.

[0042] As an example, an element, any part of an element, or any combination of elements may be implemented as a "processing system" including one or more processors. When multiple processors are implemented, the multiple processors may perform functions individually or in combination. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, system-on-a-chip (SoCs), baseband processors, field-programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gated logic components, discrete hardware circuitry, and other suitable hardware configured to perform the various functionalities described throughout this disclosure. One or more processors in the processing system can execute software. Whether referred to as software, firmware, middleware, microcode, hardware description language, or other terms, software should be broadly interpreted as instructions, instruction sets, code, code segments, program code, programs, subroutines, software components, applications, software applications, software packages, routines, subroutines, objects, executable files, threads of execution, procedures, functions, or any combination thereof.

[0043] Therefore, in one or more example aspects, specific implementations, and / or use cases, the described functionality may be implemented in hardware, software, or any combination thereof. If implemented in software, the functionality may be stored or encoded as one or more instructions or code on a computer-readable medium. Computer-readable media include computer storage media. Storage media may be any available medium accessible to a computer. By way of example, such computer-readable media may include random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disc storage devices, magnetic disk storage devices, other magnetic storage devices, combinations of these types of computer-readable media, or any other medium that can be used to store computer-executable code in the form of instructions or data structures accessible to a computer.

[0044] While aspects, implementations, and / or use cases are described herein by way of example, additional or different aspects, implementations, and / or use cases may arise in many different arrangements and scenarios. The aspects, implementations, and / or use cases described herein can be implemented across many different platform types, devices, systems, shapes, sizes, and package arrangements. For example, aspects, implementations, and / or use cases may arise via integrated chip implementations and other devices based on non-modular components (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail / purchasing devices, medical devices, AI-enabled devices, etc.). While some examples may or may not be specific to a use case or application, the described examples may exhibit broad applicability. Aspects, implementations, and / or use cases can range from chip-level or modular components to non-modular, non-chip-level implementations, and further to aggregated, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more of the technologies described herein. In some practical settings, devices incorporating the described aspects and features may also include additional components and features for implementing and practicing the claimed and described aspects. For example, the transmission and reception of wireless signals necessarily involve multiple components for analog and digital purposes (e.g., hardware components including antennas, RF chains, power amplifiers, modulators, buffers, processors, interleavers, adders / summers, etc.). The techniques described herein can be practiced in a wide variety of devices, chip-level components, systems, distributed arrangements, aggregated or decomposed components, end-user equipment, etc., of various sizes, shapes, and configurations.

[0045] The deployment of communication systems such as 5G NR systems can be arranged in a variety of ways using various components or parts. In a 5G NR system or network, network nodes, network entities, network mobility elements, radio access network (RAN) nodes, core network nodes, network elements or network equipment (such as base stations (BS)), or one or more units (or components) performing base station functionality can be implemented in aggregated or decomposed architectures. For example, BSs (such as Node B (NB), evolved NB (eNB), NR BS, 5G NB, access point (AP), transmit / receive point (TRP), or cell, etc.) can be implemented as aggregated base stations (also known as standalone BS or monolithic BS) or decomposed base stations.

[0046] Aggregated base stations can be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node. Decentralized base stations can be configured to utilize a protocol stack that is physically or logically distributed across two or more units, such as one or more central or centralized units (CUs), one or more distributed units (DUs), or one or more radio units (RUs). In some respects, the CU may be implemented within a RAN node, and one or more DUs may co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other RAN nodes. DUs may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU may be implemented as a virtual unit, namely a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU).

[0047] Base station operation or network design can take into account the aggregation characteristics of base station functionality. For example, decomposed base stations can be utilized in Integrated Access Backhaul (IAB) networks, Open Radio Access Networks (O-RAN (such as network configurations initiated by the O-RAN Alliance)), or Virtualized Radio Access Networks (vRAN, also known as Cloud Radio Access Networks (C-RAN)). Decomposition can include distributing functionality across two or more units in various physical locations, as well as virtually distributing the functionality of at least one unit, which enables flexibility in network design. The various units of a decomposed base station or decomposed RAN architecture can be configured to communicate wirelessly with at least one other unit.

[0048] Figure 1 Figure 100 illustrates an example of a wireless communication system and access network. The illustrated wireless communication system includes a decomposed base station architecture. The decomposed base station architecture may include one or more CUs 110, which may communicate directly with the core network 120 via a backhaul link, or indirectly with the core network 120 via one or more decomposed base station units, such as a near real-time (near-RT) RAN Intelligent Controller (RIC) 125 via an E2 link, or a non-real-time (non-RT) RIC 115 associated with a Service Management and Orchestration (SMO) framework 105, or both. CUs 110 may communicate with one or more DUs 130 via a corresponding midhaul link (such as an F1 interface). DUs 130 may communicate with one or more RUs 140 via a corresponding fronthaul link. RUs 140 may communicate with a corresponding UE 104 via one or more radio frequency (RF) access links. In some implementations, a UE 104 may be served simultaneously by multiple RUs 140.

[0049] Each of the units (i.e., CU 110, DU 130, RU 140, and near-RT RIC 125, non-RT RIC 115, and SMO frame 105) may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via wired or wireless transmission media. Each unit in the unit, or an associated processor or controller providing instructions to the communication interfaces of these units, may be configured to communicate with one or more other units via transmission media. For example, these units may include wired interfaces configured to receive signals or transmit signals to one or more other units via wired transmission media. Additionally, these units may include wireless interfaces that may include receivers, transmitters, or transceivers (such as RF transceivers) configured to receive signals via wireless transmission media and / or transmit signals to one or more other units.

[0050] In some aspects, the CU 110 can host one or more higher-level control functions. Such control functions may include Radio Resource Control (RRC), Packet Data Convergence Protocol (PDCP), Serving Data Adaptation Protocol (SDAP), etc. Each control function can be implemented using an interface configured to signal to other control functions hosted by the CU 110. The CU 110 can be configured to handle user plane functionality (i.e., Central Unit-User Plane (CU-UP)), control plane functionality (i.e., Central Unit-Control Plane (CU-CP)), or a combination thereof. In some implementations, the CU 110 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 110 can be implemented to communicate with the DU 130 for network control and signaling, as needed.

[0051] DU 130 may correspond to a logic unit that includes one or more base station functions for controlling the operation of one or more RU 140s. In some aspects, DU 130 may at least partially host one or more of the Radio Link Control (RLC) layer, Media Access Control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.) according to functional splits (such as those defined by 3GPP). In some aspects, DU 130 may further host one or more low PHY layers. Each layer (or module) may be implemented using an interface configured to communicate signals with other layers (and modules) hosted by DU 130 or with control functions hosted by CU 110.

[0052] Lower-layer functionality can be implemented by one or more RU 140s. In some deployments, an RU140 controlled by a DU 130 may correspond to a logical node that hosts RF processing functions or low-PHY layer functions (such as performing Fast Fourier Transform (FFT), Inverse FFT (iFFT), digital beamforming, Physical Random Access Channel (PRACH) extraction and filtering, or both, based at least in part on functional decomposition (such as lower-layer functional decomposition). In such architectures, the RU 140 may be implemented to handle over-the-air (OTA) communications with one or more UEs 104. In some specific implementations, the real-time and non-real-time aspects of control plane and user plane communications with the RU 140 may be controlled by the corresponding DU 130. In some scenarios, this configuration allows the DU 130 and CU 110 to be implemented in cloud-based RAN architectures such as vRAN architectures.

[0053] SMO framework 105 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, SMO framework 105 can be configured to support 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, SMO framework 105 can be configured to interact with a cloud computing platform such as Open Cloud (O-Cloud) 190 to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface such as the O2 interface. Such virtualized network elements may include, but are not limited to, CU 110, DU 130, RU 140, and near-RT RIC 125. In some implementations, SMO framework 105 can communicate with hardware aspects of the 4G RAN, such as Open eNB (O-eNB) 111, via the O1 interface. Additionally, in some implementations, SMO framework 105 can communicate directly with one or more RU 140s via the O1 interface. SMO framework 105 may also include a non-RT RIC 115 configured to support the functionality of SMO framework 105.

[0054] The non-RT RIC 115 can be configured to include logical functions enabling non-real-time control and optimization of RAN elements and resources, including artificial intelligence (AI) / machine learning (ML) workflows for model training and updates, or policy-based guidance for applications / features in the near-RT RIC 125. The non-RT RIC 115 can be coupled to or communicate with the near-RT RIC 125, such as via an A1 interface. The near-RT RIC 125 can be configured to include logical functions enabling near real-time control and optimization of RAN elements and resources via data collection and actions through an interface such as an E2 interface, connecting one or more CU 110s, one or more DU 130s, or both, and O-eNBs to the near-RT RIC 125.

[0055] In some implementations, to generate AI / ML models to be deployed in the near-RT RIC 125, the non-RT RIC 115 may receive parameters or external enrichment information from an external server. This information can be utilized by the near-RT RIC 125 and may be received from non-network data sources or network functions at the SMO framework 105 or the non-RT RIC 115. In some examples, the non-RT RIC 115 or the near-RT RIC 125 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 115 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions via the SMO framework 105 (such as reconfiguration via O1) or by creating RAN management policies (such as A1 policies).

[0056] At least one of CU 110, DU 130, and RU 140 may be referred to as base station 102. Therefore, base station 102 may include one or more of CU 110, DU 130, and RU 140 (each component is indicated by a dashed line to indicate that each component may or may not be included in base station 102). Base station 102 provides UE 104 with an access point to core network 120. Base station 102 may include macro cells (high-power cellular base stations) and / or small cells (low-power cellular base stations). Small cells include femtocells, picocells, and microcells. A network that includes both small cells and macro cells may be referred to as a heterogeneous network. A heterogeneous network may also include an evolved home node B (eNB) (HeNB), which can provide service to a restricted group referred to as a closed subscriber group (CSG). The communication link between RU 140 and UE 104 may include uplink (UL) transmission (also known as reverse link) from UE 104 to RU 140 and / or downlink (DL) transmission (also known as forward link) transmission from RU 140 to UE 104. The communication link may utilize multiple-input multiple-output (MIMO) antenna techniques, including spatial multiplexing, beamforming, and / or transmit diversity. The communication link may use one or more carriers. For each carrier allocated in a carrier aggregation of up to Yx MHz (x component carriers) for transmission in each direction, base station 102 / UE 104 may use a spectrum with a bandwidth of up to Y MHz (e.g., 5MHz, 10MHz, 15MHz, 20MHz, 100MHz, 400MHz, etc.). Carriers may be adjacent to each other or may not be adjacent to each other. Carrier allocation may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated to DL compared to UL). Component carriers may include primary component carriers and one or more secondary component carriers. The primary component carrier can be referred to as the primary cell (PCell) and the secondary component carrier can be referred to as the secondary cell (SCell).

[0057] Some UEs 104 can communicate with each other using device-to-device (D2D) communication link 158. D2D communication link 158 can use DL / UL wireless wide area network (WWAN) spectrum. D2D communication link 158 can use one or more sidelink channels, such as Physical Sidelink Broadcast Channel (PSBCH), Physical Sidelink Discovery Channel (PSDCH), Physical Sidelink Shared Channel (PSSCH), and Physical Sidelink Control Channel (PSCCH). D2D communication can be performed through various wireless D2D communication systems, such as Bluetooth. ™ (Bluetooth is a trademark of the Bluetooth Special Interest Group (SIG), and is based on the IEEE 802.11 standard for Wi-Fi.) ™(Wi-Fi is a trademark of the Wi-Fi Alliance), LTE, or NR.

[0058] The wireless communication system may also include a Wi-Fi AP 150, which communicates with the UE 104 (also referred to as a Wi-Fi station (STA)) via a communication link 154, for example, in an unlicensed spectrum such as 5 GHz. When communicating in unlicensed spectrum, the UE 104 / AP 150 may perform a free channel assessment (CCA) to determine whether a channel is available before communication.

[0059] The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc., based on frequency / wavelength. In 5G NR, two initial operating bands have been designated as frequency ranges FR1 (410MHz to 7.125GHz) and FR2 (24.25GHz to 52.6GHz). Although a portion of FR1 is greater than 6GHz, FR1 is generally (interchangeably) referred to as the "sub-6GHz" band in various documents and articles. Similar naming issues sometimes occur with FR2, which is generally (interchangeably) referred to as the "millimeter wave" band in documents and articles, although this is distinct from the Extremely High Frequency (EHF) band (30GHz to 300GHz) designated as "millimeter wave" by the International Telecommunication Union (ITU).

[0060] The frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR studies have designated the operating bands for these mid-band frequencies as the frequency range designation FR3 (7.125 GHz to 24.25 GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, thus effectively extending the features of FR1 and / or FR2 to mid-band frequencies. Additionally, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been designated as the frequency range designations FR2-2 (52.6 GHz to 71 GHz), FR4 (71 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Each of these higher bands falls within the EHF band.

[0061] In view of the above, unless otherwise specified, the term "below 6 GHz" as used herein can broadly refer to frequencies less than 6 GHz, within FR1, or including intermediate frequency band frequencies. Furthermore, unless otherwise specified, the term "millimeter wave" as used herein can broadly refer to frequencies that can include intermediate frequency band frequencies, within FR2, FR4, FR2-2 and / or FR5, or within the EHF band.

[0062] Base station 102 and UE 104 may each include multiple antennas (such as antenna elements, antenna panels, and / or antenna arrays) to facilitate beamforming. Base station 102 may transmit beamformed signals 182 to UE 104 in one or more transmit directions. UE 104 may receive beamformed signals from base station 102 in one or more receive directions. UE 104 may also transmit beamformed signals 184 to base station 102 in one or more transmit directions. Base station 102 may receive beamformed signals from UE 104 in one or more receive directions. Base station 102 / UE 104 may perform beamforming training to determine the optimal receive and transmit directions for each of base station 102 / UE 104. The transmit and receive directions of base station 102 may be the same or different. The transmit and receive directions of UE 104 may be the same or different.

[0063] Base station 102 may include and / or be referred to as gNB, Node B, eNB, access point, transceiver base station, radio base station, radio transceiver, transceiver function, basic service set (BSS), extended service set (ESS), TRP, network node, network entity, network equipment, or some other suitable terminology. Base station 102 may be implemented as an integrated access and backhaul (IAB) node, relay node, sidelink node, aggregated (monolithic) base station with baseband units (BBU) (including CU and DU) and RU, or may be implemented as a decomposed base station including one or more of CU, DU, and / or RU. A collection of base stations that may include decomposed base stations and / or aggregated base stations may be referred to as Next Generation (NG) RAN (NG-RAN).

[0064] The core network 120 may include Access and Mobility Management Function (AMF) 161, Session Management Function (SMF) 162, User Plane Function (UPF) 163, Unified Data Management (UDM) 164, one or more location servers 168, and other functional entities. AMF 161 is the control node that handles signaling between UE 104 and the core network 120. AMF 161 supports registration management, connection management, mobility management, and other functions. SMF 162 supports session management and other functions. UPF 163 supports packet routing, packet forwarding, and other functions. UDM 164 supports authentication and key agreement (AKA) credential generation, user identity processing, access authorization, and subscription management. One or more location servers 168 are exemplified as including a Gateway Mobile Location Center (GMLC) 165 and a Location Management Function (LMF) 166. However, generally, one or more location servers 168 may include one or more location / positioning servers, which may include one or more of GMLC 165, LMF 166, Position Determination Entity (PDE), Serving Mobile Location Center (SMLC), Mobile Location Center (MPC), etc. GMLC 165 and LMF 166 support UE location services. GMLC 165 provides an interface for clients / applications (e.g., emergency services) to access UE location information. LMF 166 receives measurement and auxiliary information from NG-RAN and UE 104 via AMF 161 to calculate the location of UE 104. NG-RAN may use one or more positioning methods to determine the location of UE 104. Positioning UE 104 may involve signal measurement, location estimation, and optional rate calculation based on these measurements. Signal measurement may be performed by UE 104 and / or base station 102 serving UE 104. The measured signals may be based on one or more of the following: Satellite Positioning System (SPS) 170 (e.g., one or more of Global Navigation Satellite System (GNSS), Global Positioning System (GPS), Non-Terrestrial Network (NTN) or other satellite positioning / location systems), LTE signals, Wireless Local Area Network (WLAN) signals, Bluetooth signals, Terrestrial Beacon System (TBS), sensor-based information (e.g., barometric pressure sensor, motion sensor), NR Enhanced Cell ID (NR E-CID) method, NR signals (e.g., multiple round-trip time (multiple RTT), DL departure angle (DL-AoD), DL time difference of arrival (DL-TDOA), UL time difference of arrival (UL-TDOA), and UL angle of arrival (UL-AoA) positioning) and / or other systems / signals / sensors.

[0065] Examples of UE 104 include cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, GPS devices, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablets, smart devices, wearable devices, vehicles, electricity meters, air pumps, large or small kitchen appliances, healthcare devices, implants, sensors / actuators, displays, or any other similarly functional device. Some UEs in UE 104 may be referred to as IoT devices (e.g., parking meters, air pumps, toasters, vehicles, heart monitors, etc.). UE 104 may also be referred to as a station, mobile station, subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, mobile phone, user agent, mobile client, client, or some other suitable terminology. In some scenarios, the term UE may also be applied to one or more companion devices, such as in a device constellation arrangement. One or more of these devices may access the network together and / or individually.

[0066] Refer again Figure 1In some aspects, UE 104 may include an operation mode component 198. In some aspects, operation mode component 198 may be configured to receive an SBFD time and frequency configuration for allocating resources for communication with a network entity based on an SBFD mode; obtain a UE operation mode for the resources, wherein the UE operation mode is either a UE FD mode or a UE HD mode; and, based on the UE operation mode, communicate with the network entity in the resources allocated to the UE. In some aspects, operation mode component 198 may be configured to receive a time and frequency configuration for allocating resources for communication with a network entity based on FD operation, wherein the UE operates in the resources in either a UE HD mode or a UE FD mode; perform an SI measurement for the UE in response to the time and frequency configuration; and report an SI indication indicating the SI measurement to the network entity. In some aspects, base station 102 may include an operation mode component 199. In some aspects, the operation mode component 199 can be configured to transmit SBFD time and frequency configurations for allocating resources for communication with the UE based on SBFD mode; and to communicate with the UE in the allocated resources based on the UE operation mode for the resources, wherein the UE operation mode is either UE FD mode or UE HD mode. In some aspects, the operation mode component 199 can be configured to transmit time and frequency configurations for allocating resources for communication with the UE based on FD operation, wherein the UE operates in the resources in either UE HD mode or UE FD mode; and to receive from the UE an SI indication indicating SI measurements for the UE. While the following description may focus on 5G NR, the concepts described herein may be applicable to other similar domains, such as LTE, LTE-A, CDMA, GSM, and other wireless technologies.

[0067] Figure 2A Figure 200 illustrates an example of the first subframe within a 5G NR frame structure. Figure 2B Figure 230 illustrates an example of a DL channel within a 5G NR subframe. Figure 2C Figure 250 is an example of a second subframe within a 5G NR frame structure. Figure 2D Figure 280 illustrates an example of a UL channel within a 5G NR subframe. The 5G NR frame structure can be Frequency Division Duplex (FDD) (where subframes within a specific set of subcarriers (carrier system bandwidth) are dedicated to either DL or UL) or Time Division Duplex (TDD) (where subframes within a specific set of subcarriers (carrier system bandwidth) are dedicated to both DL and UL). Figure 2A , Figure 2CIn the provided example, the 5G NR frame structure is assumed to be TDD, where subframe 4 is configured with slot format 28 (most of which are DL), where D is DL, U is UL, and F is flexible and can be used between DL / UL, and subframe 3 is configured with slot format 1 (all of which are UL). Although subframes 3 and 4 are shown as having slot formats 1 and 28 respectively, any particular subframe can be configured with any of the various available slot formats 0-61. Slot formats 0 and 1 are both DL and UL, respectively. Other slot formats 2-61 include a mixture of DL, UL, and flexible symbols. The UE is configured using the slot format via the received Slot Format Indicator (SFI) (dynamically configured via DL Control Information (DCI) or semi-statically / statically configured via Radio Resource Control (RRC) signaling). Note that the following description also applies to the 5G NR frame structure as TDD.

[0068] Figures 2A to 2D The frame structure is illustrated, and aspects of this disclosure are applicable to other wireless communication technologies that may have different frame structures and / or different channels. A frame (10 ms) can be divided into 10 equal-sized subframes (1 ms). Each subframe may include one or more time slots. Subframes may also include micro-time slots, which may include 7, 4, or 2 symbols. Each time slot may include 14 or 12 symbols, depending on whether the cyclic prefix (CP) is normal or extended. For normal CP, each time slot may include 14 symbols, and for extended CP, each time slot may include 12 symbols. Symbols on the DL may be CP Orthogonal Frequency Division Multiplexing (OFDM) (CP-OFDM) symbols. Symbols on the UL may be CP-OFDM symbols (for high-throughput scenarios) or Discrete Fourier Transform (DFT) Extended OFDM (DFT-s-OFDM) symbols (for power-constrained scenarios; limited to single-stream transmission). The number of time slots within a subframe is based on the CP and a parameter set. The parameter set defines the subcarrier spacing (SCS) (see Table 1). The symbol length / duration can be scaled by 1 / SCS.

[0069]

[0070] Table 1: Parameter Set, SCS, and CP

[0071] For a normal CP (14 symbols / slot), different parameter sets µ 0 through 4 allow 1, 2, 4, 8, and 16 slots per subframe, respectively. For the extended CP, parameter set 2 allows 4 slots per subframe. Therefore, for a normal CP and parameter set µ, there are 14 symbols per slot and 2 slots per subframe. µ One time slot. The subcarrier spacing can be equal to ,in The parameter sets are 0 to 4. Therefore, the subcarrier spacing is 15 kHz for parameter set µ=0 and 240 kHz for parameter set µ=4. The symbol length / duration is negatively correlated with the subcarrier spacing. Figures 2A to 2D Examples of a normal frequency division multiplexing (CP) with 14 symbols per time slot and a parameter set of µ=2 with 4 time slots per subframe are provided. The time slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs. Within the frame set, there may be one or more distinct bandwidth portions (BWPs) of frequency division multiplexing (see [link to relevant documentation]). Figure 2B Each BWP can have a specific set of parameters and CP (normal or extended).

[0072] A resource grid can be used to represent the frame structure. Each time slot consists of a resource block (RB) extending for 12 consecutive subcarriers (also known as a physical RB (PRB)). The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0073] like Figure 2A As illustrated, some of the REs carry reference (pilot) signals (RS) for the UE. RS may include demodulation RS (DM-RS) (indicated as R for a particular configuration, but other DM-RS configurations are possible) and channel state information reference signals (CSI-RS) for channel estimation at the UE. RS may also include beam measurement RS (BRS), beam refinement RS (BRRS), and phase tracking RS (PT-RS).

[0074] Figure 2BExamples of various DL channels within a subframe of a frame are illustrated. The Physical Downlink Control Channel (PDCCH) carries the DCI within one or more Control Channel Elements (CCEs) (e.g., 1, 2, 4, 8, or 16 CCEs), each CCE comprising six RE Groups (REGs), each REG comprising 12 consecutive REs in the OFDM symbol of the RB. A PDCCH within a BWP can be referred to as a Control Resource Set (CORESET). The UE is configured to monitor PDCCH candidates in the PDCCH search space (e.g., the common search space, the UE-specific search space) during PDCCH monitoring timing on the CORESET, where the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs may be located at higher and / or lower frequencies on the channel bandwidth. The Primary Synchronization Signal (PSS) may be located within symbol 2 of a specific subframe of the frame. The PSS is used by UE 104 to determine subframe / symbol timing and physical layer identification. The Secondary Synchronization Signal (SSS) may be located within symbol 4 of a specific subframe of the frame. The SSS is used by the UE to determine the Physical Layer Cell Identifier Group Number and radio frame timing. Based on the Physical Layer Identifier and the Physical Layer Cell Identifier Group Number, the UE can determine the Physical Cell Identifier (PCI). Based on the PCI, the UE can determine the location of the DM-RS. The Physical Broadcast Channel (PBCH), carrying the Master Information Block (MIB), can be logically grouped with the PSS and SSS to form a Synchronization Signal (SS) / PBCH block (also known as an SS block (SSB)). The MIB provides the number of RBs in the system bandwidth and the System Frame Number (SFN). The Physical Downlink Shared Channel (PDSCH) carries user data, broadcast system information not transmitted via the PBCH (such as System Information Block (SIB)), and paging messages.

[0075] like Figure 2C As illustrated, some REs in the REs carry DM-RS (indicated as R for one particular configuration, but other DM-RS configurations are possible) for channel estimation at the base station. The UE can transmit DM-RS for the Physical Uplink Control Channel (PUCCH) and DM-RS for the Physical Uplink Shared Channel (PUSCH). The PUSCH DM-RS can be transmitted in the first or first two symbols of the PUSCH. Depending on whether a short or long PUCCH is transmitted and depending on the specific PUCCH format used, the PUCCH DM-RS can be transmitted in different configurations. The UE can transmit a Sounding Reference Signal (SRS). The SRS can be transmitted in the last symbol of a subframe. The SRS can have a comb structure, and the UE can transmit the SRS on one of the comb teeth. The SRS can be used by the base station for channel quality estimation to enable frequency-dependent scheduling of the UL.

[0076] Figure 2DExamples of various UL channels within a subframe of a frame are illustrated. The PUCCH may be located as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicators (CQI), pre-decoding matrix indicators (PMI), rank indicators (RI), and hybrid automatic repeat request (HARQ) acknowledgment (ACK) (HARQ-ACK) feedback (i.e., one or more HARQ ACK bits indicating one or more ACKs and / or negative ACKs (NACKs)). The PUCCH carries data and may additionally be used to carry buffer status reports (BSR), power clearance reports (PHR), and / or UCIs.

[0077] Figure 3 This is a block diagram illustrating communication between base station 310 and UE 350 in the access network. In the DL, Internet Protocol (IP) packets can be provided to controller / processor 375. Controller / processor 375 implements Layer 3 and Layer 2 functionality. Layer 3 includes the Radio Resource Control (RRC) layer, and Layer 2 includes the Service Data Adaptation Protocol (SDAP) layer, Packet Data Convergence Protocol (PDCP) layer, Radio Link Control (RLC) layer, and Media Access Control (MAC) layer. The controller / processor 375 provides RRC layer functionality associated with broadcasting system information (e.g., MIB, SIB), RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), inter-Radio Access Technology (RAT) mobility, and measurement configuration for UE measurement reporting; PDCP layer functionality associated with header compression / decompression, security (encryption, decryption, integrity protection, integrity verification), and handover support functions; RLC layer functionality associated with the delivery of upper-layer packet data units (PDUs), error correction via ARQ, concatenation, segmentation, and reassembly of RLC service data units (SDUs), resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction via HARQ, priority handling, and logical channel priority ordering.

[0078] Transmit (TX) processor 316 and receive (RX) processor 370 implement Layer 1 functionality associated with various signal processing functions. Layer 1 (which includes the physical (PHY) layer) may include error detection on the transport channel, forward error correction (FEC) decoding / decoding of the transport channel, interleaving, rate matching, mapping to the physical channel, modulation / demodulation of the physical channel, and MIMO antenna processing. TX processor 316 processes the mapping to the signal constellation based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-order phase shift keying (M-PSK), M-order quadrature amplitude modulation (M-QAM)). The decoded and modulated symbols can then be divided into parallel streams. Each stream can then be mapped to OFDM subcarriers, multiplexed with a reference signal (e.g., a pilot) in the time and / or frequency domains, and then combined using inverse fast Fourier transform (IFFT) to produce a physical channel carrying a stream of time-domain OFDM symbols. The OFDM stream undergoes spatial pre-decoding to generate multiple spatial streams. Channel estimation from channel estimator 374 can be used to determine the decoding and modulation scheme, as well as for spatial processing. The channel estimation can be derived from a reference signal transmitted by UE 350 and / or channel condition feedback. Each spatial stream can then be provided to a different antenna 320 via a separate transmitter 318Tx. Each transmitter 318Tx can utilize the corresponding spatial stream to modulate a radio frequency (RF) carrier for transmission.

[0079] At UE 350, each receiver 354Rx receives signals via its corresponding antenna 352. Each receiver 354Rx recovers the information modulated onto the RF carrier and provides that information to the receive (RX) processor 356. The TX processor 368 and RX processor 356 implement Layer 1 functionality associated with various signal processing functions. The RX processor 356 can perform spatial processing on the information to recover any spatial stream destined for UE 350. If multiple spatial streams are destined for UE 350, the RX processor 356 can combine them into a single OFDM symbol stream. The RX processor 356 then uses a Fast Fourier Transform (FFT) to transform the OFDM symbol stream from the time domain to the frequency domain. The frequency domain signal consists of a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier, along with the reference signal, are recovered and demodulated by determining the most probable signal constellation point transmitted by base station 310. These soft decisions can be based on a channel estimate calculated by channel estimator 358. The soft decision is then decoded and deinterleaved to recover the data and control signals originally transmitted by base station 310 on the physical channel. The data and control signals are then provided to controller / processor 359, which implements layer 3 and layer 2 functionality.

[0080] The controller / processor 359 may be associated with at least one memory 360 storing program code and data. The at least one memory 360 may be referred to as a computer-readable medium. In the UL, the controller / processor 359 provides demultiplexing, packet reassembly, decryption, header decompression, and control signal processing between transport and logical channels to recover IP packets. The controller / processor 359 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0081] Similar to the functionality described in conjunction with DL transmission performed by base station 310, controller / processor 359 provides RRC layer functionality associated with system information (e.g., MIB, SIB) acquisition, RRC connectivity, and measurement reporting; PDCP layer functionality associated with header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functionality associated with upper-layer PDU delivery, error correction via ARQ, concatenation, segmentation, and reassembly of RLC SDUs, resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction via HARQ, priority handling, and logical channel priority ordering.

[0082] The TX processor 368 can use the reference signal transmitted from the base station 310 or the channel estimate derived from feedback by the channel estimator 358 to select an appropriate decoding and modulation scheme and facilitate spatial processing. The spatial stream generated by the TX processor 368 can be provided to different antennas 352 via individual transmitters 354Tx. Each transmitter 354Tx can use the corresponding spatial stream to modulate an RF carrier for transmission.

[0083] UL transmission is processed at base station 310 in a manner similar to that described in conjunction with the receiver function at UE 350. Each receiver 318Rx receives signals via its corresponding antenna 320. Each receiver 318Rx recovers the information modulated onto the RF carrier and provides that information to RX processor 370.

[0084] The controller / processor 375 may be associated with at least one memory 376 storing program code and data. The at least one memory 376 may be referred to as a computer-readable medium. In the UL, the controller / processor 375 provides demultiplexing, packet reassembly, decryption, header decompression, and control signal processing to recover IP packets between transport and logical channels. The controller / processor 375 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0085] At least one of the TX processor 368, RX processor 356, and controller / processor 359 can be configured to perform coupling. Figure 1 The various aspects of the operation mode component 198.

[0086] At least one of the TX processor 316, RX processor 370, and controller / processor 375 can be configured to perform coupled operations. Figure 1 The various aspects of the operation mode component 199.

[0087] The example aspects presented herein provide methods and apparatus for interaction between SBFD network operations and HD UE and SBFD UE operations, including detailed signals for different combinations of UE and network SBFD operations.

[0088] Wireless communication systems can be configured to share available system resources and provide various telecommunications services (e.g., telephone, video, data, messaging, broadcasting, etc.) based on multiple access technologies that support communication with multiple users. Full-duplex operation (where wireless devices exchange time-overlapping uplink and downlink communications) enables more efficient use of the wireless spectrum. Full-duplex operation can include simultaneous transmission and reception within the same frequency range. In some examples, the frequency range can be a mmW frequency range, such as frequency range 2 (FR2). In some examples, the frequency range can be a sub-6 GHz frequency range, such as frequency range 1 (FR1). Full-duplex communication reduces latency. For example, full-duplex operation allows a UE to receive downlink signals in only uplink time slots, which reduces downlink communication latency. Full-duplex communication improves spectrum efficiency, such as per cell or per UE. Full-duplex communication enables more efficient use of wireless resources.

[0089] Figures 4A to 4C Various modes of full-duplex communication are illustrated. Full-duplex communication supports transmitting and receiving information in the same frequency band with overlapping time signatures. In this way, spectral efficiency can be improved compared to half-duplex communication, which supports uplink and downlink communication that transmits or receives information in one direction at a time without overlap. Due to the simultaneous Tx / Rx nature of full-duplex communication, the UE or base station may experience self-interference caused by signal leakage from its local transmitter to its local receiver. Furthermore, the UE or base station may also experience interference from other devices, such as transmissions from a second UE or a second base station. Such interference (e.g., self-interference or interference caused by other devices) can affect communication quality or even lead to data loss.

[0090] Figure 4AA first example 400 of full-duplex communication is shown, wherein a first base station 402a is in full-duplex communication with a first UE 404a and a second UE 406a. The first UE 404a and the second UE 406a can be configured for half-duplex or full-duplex communication. Figure 4A An example is illustrated of a first UE 404a performing downlink reception and a second UE 406a performing uplink transmission. The second UE 406a may transmit a first uplink signal to a first base station 402a and other base stations, such as a second base station 408a adjacent to the second UE 406a. The first base station 402a transmits a downlink signal to the first UE 404a concurrently (e.g., at least partially overlapping in time) with the uplink signal received from the second UE 406a. The base station 402a may experience self-interference at its receiving antenna, which is receiving an uplink signal from the UE 406a, due to receiving at least a portion of the downlink signal transmitted to the UE 404a. The base station 402a may experience additional interference due to signals from the second base station 408a. Interference may also occur at the first UE 404a based on signals from the second base station 408a and uplink signals from the second UE 406a.

[0091] Figure 4B A second example 410 of full-duplex communication is shown, in which a first base station 402b and a first UE 404b are in full-duplex communication. In this example, UE 404b also operates in full-duplex mode. The first base station 402b and UE 404b receive and transmit communications that overlap in time and are in the same frequency band. The base station and UE may each experience self-interference because signals transmitted from the devices leak to a receiver at the same device (e.g., are received by that receiver). The first UE 404b may experience additional interference based on one or more signals transmitted from a second UE 406b and / or a second base station 408b adjacent to the first UE 404b.

[0092] Figure 4C A third example 420 of full-duplex communication is shown, in which a first UE 404c transmits and receives full-duplex communication with a first base station 402c and a second base station 408c. The first base station 402c and the second base station 408c can be used as multiple transmit / receive points (multiple TRPs) for UL and DL communication with the UE 404c. The second base station 408c can also exchange communication with a second UE 406c. Figure 4CIn this configuration, the first UE 404c can transmit an uplink signal to the first base station 402c, which overlaps in time with the reception of a downlink signal from the second base station 408c. As a result of receiving at least part of the first signal while receiving the second signal, the first UE 404c may experience self-interference, for example, when the UE is attempting to receive a signal from another base station 408c, the uplink signal of the UE destined for base station 402c may leak to the UE's receiver (e.g., be received by that receiver). The first UE 404c may experience additional interference from the second UE 406c.

[0093] Figure 4D A fourth example 430 of full-duplex communication is shown, in which a first base station 402d engages in full-duplex communication with a first UE 404d and transmits downlink communication to a second UE 406d. In this example, the first UE 404d is operating in full-duplex mode, and the second UE 406d is operating in half-duplex mode. The first base station 402d and the first UE 404d receive and transmit communications that overlap in time and are in the same frequency band. The base station 402d and the first UE 404d may each experience self-interference because signals transmitted from the corresponding devices leak to a receiver at the same device (e.g., received by that receiver). The base station 402d may further experience cross-link interference due to signals transmitted by the base station 408d. When receiving downlink communication from the base station 402d, the second UE 406d may experience cross-link interference from uplink transmissions from the first UE 404d.

[0094] Full-duplex communication can occur within the same frequency band. Uplink and downlink communication can occur in different frequency subbands, the same frequency subband, or partially overlapping frequency subbands. Figure 5 Examples 500 and 510 illustrate in-band full-duplex (IBFD) resources, and a third example 520 illustrates sub-band full-duplex resources. In IBDF, signals can be transmitted and received in overlapping times and frequencies. As shown in the first example 500, the time and frequency allocation of transmit resource 502 may completely overlap with the time and frequency allocation of receive resource 504. In the second example 510, the time and frequency allocation of transmit resource 512 may partially overlap with the time and frequency allocation of receive resource 514.

[0095] In contrast to sub-band FDD, IBFD allows transmit and receive resources to overlap in time using different frequencies, as illustrated in the third example 520. In the third example 520, the UL (Upper Limit) transmit resource 522 is separated from the receive resource 524 by a guard band 526. The guard band can be a frequency resource provided between the transmit resource 522 and the receive resource 524, or a gap within a frequency resource. Separating transmit and receive frequency resources using a guard band helps reduce self-interference. Transmit and receive resources adjacent to each other can be considered to have a guard bandwidth of 0. Since the output signal from the wireless device can extend beyond the transmit resource, the guard band can reduce interference experienced by the wireless device. Sub-band FDD can also be referred to as "flexible duplex".

[0096] If full-duplex operation is used for the UE or equipment implementing UE functionality, then transmit resources 502, 512, and 522 may correspond to uplink resources, and receive resources 504, 514, and 524 may correspond to downlink resources. Alternatively, if full-duplex operation is used for the base station or equipment implementing base station functionality, then transmit resources 502, 512, and 522 may correspond to downlink resources, and receive resources 504, 514, and 524 may correspond to uplink resources.

[0097] On the network side, SBFD operation allows the network (e.g., a base station) to serve the UE simultaneously on both DL and UL in the corresponding subband. Figure 6 This is a diagram 600 illustrating an example of a network SBFD operation. For example... Figure 6 As shown, a network (e.g., base station 604) can operate in SBFD mode, simultaneously serving one UE (UE1 602) on the DL subband and another UE (UE2 606) on the UL subband. Various subband patterns are available for network SBFD operation. A first example pattern (SBFD pattern 1 610) follows a D+U+D configuration, which includes a DL subband 612, a UL subband 614, and another DL subband 616. A second example pattern (SBFD pattern 2 620) utilizes a D+U configuration, which includes a DL subband 622 and a UL subband 624. To minimize interference between the DL and UL subbands, one or more guard bands (e.g., guard bands 618, 626) can be provided, which include multiple resource blocks (RBs) between the DL and UL subbands.

[0098] SBFD operation allows for the simultaneous transmission and reception of downlink and uplink signals on a subband basis. SBFD operation can increase the UL duty cycle, resulting in reduced latency. For example, SBFD operation allows UL signals to be transmitted in the UL subband within DL time slots or flexible time slots. On the other hand, SBFD operation also allows DL signals to be received in the DL subband within UL time slots. These adaptations contribute to reduced latency. Additionally, SBFD helps improve UL coverage, for example, by enabling UL transmission simultaneously with DL communication. Furthermore, SBFD operation enhances system capacity, resource utilization, and overall spectral efficiency, and optimizes network performance by enabling dynamic and flexible UL / DL resource adaptation based on UL and DL services.

[0099] In some examples, an SBFD network (e.g., an SBFD base station or a network supporting SBFD resources or SBFD operation) can operate with two HD UEs, and symbols used for HD communication and symbols used for SBFD communication can coexist, for example, overlapping in time. For example, some symbols or time slots can be semi-statically set as SBFD symbols on downlink (D) or flexible (F) symbols (e.g., for base station SBFD communication), while the remaining symbols or time slots can continue to be used as HD symbols or time slots.

[0100] In some examples, the UE can operate in SBFD mode, and the SBFD UE can communicate with the SBFD network to further enhance system capacity and UL coverage and further reduce latency. Figure 7A , Figure 7B , Figure 7C , Figure 7D These are illustrations illustrating various modes of UE operation according to various aspects of this disclosure. Figures 7A to 7D One or more of the illustrated modes can be configured and can coexist in different symbols or time slots. Additionally, the UE and / or base station may be able to switch from one mode to another, for example, based on specific timing or conditional triggering. Figure 7A This is a diagram 700 illustrating a pairing pattern between HD cell 704 and HD UE 702. HD cell 704 and HD UE 702 can communicate via DL or UL beam 710. Figure 7B This is illustration 720, showing an SBFD network working with two HD UEs. Figure 7B In this process, SBFD cell 724 can simultaneously communicate with the first HD UE (HD UE1 722) via DL beam 730 and with the second HD UE (HD UE2 726) via UL beam 732. Figure 7C This is illustration 740, showing an SBFD network working with an SBFD UE. Figure 7CIn this process, SBFD cell 724 can simultaneously transmit to SBFD UE 742 via DL beam 750 and receive from SBFD UE 742 via UL beam 752. Figure 7D Figure 760 illustrates an SBFD UE communicating with two low-capability HD cells / TRPs. Figure 7D In this configuration, the SBFD UE 742 can simultaneously communicate with the first HD cell / TRP (HD Cell1 / TRP1 764) via the DL beam 770 and with the second HD cell / TRP (HD Cell2 / TRP2 766) via the UL beam 772. From the perspective of the SBFD UE, communication with an SBFD cell (such as...) Figure 7C (as shown) and two HD cells (as shown) Figure 7D The communication between the two modes (as shown in the figure) may be difficult to distinguish, so the two modes may be transparent to the UE.

[0101] In some respects, if the UE supports SBFD communication, the SBFD network (e.g., an SBFD base station supporting SBFD communication) can configure the UE to simultaneously transmit (Tx) in the UL subband and receive (Rx) in the DL subband within an SBFD symbol or time slot. However, the SBFD network (e.g., an SBFD base station) may not configure the UE for SBFD communication on every symbol or time slot. This configuration can be flexible and based on various conditions. For example, the UE's SBFD operation can vary depending on certain operating conditions, or it can be dynamic. One such operating condition could be self-interference (SI) experienced at the UE. For example, if the SI at the SBFD UE becomes high enough to exceed a threshold level (e.g., due to factors such as clutter), the UE can request the network to restore the UE to HD mode (the network can remain in either SBFD mode or HD mode). Additionally or alternatively, the UE's SBFD configuration or operation may be affected by traffic demands in the DL or UL direction. For example, if the UE configuration grant (CG) has a greater periodicity than the resources scheduled for the UE in semi-persistent scheduling (SPS), there may be times when the UE's SPS can be paired with another UE for SBFD operations by the network, where the UE is communicating in HD mode. At other times or occasions, the UE's SPS can be paired with its own UL CG for UE SBFD operations.

[0102] Figure 8 Figure 800 illustrates an example UE SBFD configuration or operation based on various aspects of this disclosure for UE services. Figure 8Examples of the timing of Configuration Grant (CG) and Semi-Persistent Scheduling (SPS) are illustrated. Configuration grants provide the UE with periodic or semi-persistent resources that the UE can use for uplink transmissions to the network. For example, the network may provide the UE with one or more configuration grants for cyclical resources for uplink transmissions in RRC signaling. For some types of configuration grants, the UE can use the allocated resources based on RRC configuration and without activation or control signaling from the network. In other types of configuration grants, the UE may further receive, for example, an indication in MAC-CE or DCI that the configuration grant is activated or enabled for the UE's use. The UE can then use the cyclical resources of the configuration grant for uplink transmissions, for example, until the UE receives signaling from the network that the configuration grant is deactivated. In some aspects, the UE may receive RRC signaling configuring multiple configuration grants for the UE, and the UE may then receive a MAC-CE that activates one or more of the configuration grants from the RRC signaling. Configuration grants resource allocation to the UE, allowing the UE to use that resource allocation for uplink transmissions without a separate grant for individual uplink transmissions (e.g., in DCI). Similarly, SPS scheduling can allocate periodic or semi-persistent resources to the UE to receive downlink communication. Configuration grants can reduce the overhead of signaling grants to the UE and can reduce the latency of the UE transmitting uplink transmissions.

[0103] exist Figure 8 In this context, the UE's CG (e.g., UE1 CG 802, 804) has a larger periodicity than its SPS (e.g., UE1 SPS 812, 814, 816, 818). Therefore, some SPS opportunities of the UE can be paired with another UE for network-based SBFD operations, while other SPS opportunities can overlap temporally with the CG, allowing the UE to use SBFD operations to send uplink transmissions during the CG opportunity and receive downlink transmissions during the SPS opportunity. For example, UE1 SPS 814 can be paired with UE2 CG 822, and UE1 SPS 818 can be paired with UE2 CG 824 for network SBFD operations, while UE1 SPS 812 overlaps with UE1 CG 802. Therefore, UE1 can switch between SBFD operations (e.g., for 812 and 802) and half-duplex operations (e.g., for 814 or 818).

[0104] This dynamic handover may involve different operating parameters for UE SBFD and UE HD modes. These different operating parameters for different modes may include different DL modulation and decoding schemes (MCS), different UL MCS, DL beams for the UE, different layers for network communication, different pre-decoding matrix indicators (PMI), different UL beams for the UE, different UL power control (PC) parameters, and different UL timing advance (TA). Additionally, if an SBFD UE has dominant traffic in one direction, the network may pair resources for that UE with another UE for network SBFD operation.

[0105] In scenarios where another UE has an urgent UL service to transmit, the network can pair that UE with an SBFD UE for network SBFD operation, thereby adapting to the urgent service or ensuring scheduling fairness. In this case, using Dynamic Grant (DG) services, the scheduling downlink control information (DCI) can indicate whether the UE will operate in HD mode or FD mode, allowing the UE to apply appropriate pre-configured parameters. In some examples, if no mode is indicated (e.g., HD or FD mode), the UE can default to the FD mode configuration (e.g., FD antenna panel configuration and parameters).

[0106] In some respects, the UE can operate in SBFD mode for some SBFD symbols or slots, while in other SBFD symbols or slots, the UE operates in HD mode (where the network operates in SBFD mode). Figure 9 Figure 900 illustrates a UE operating in SBFD mode and HD mode at different symbols according to various aspects of this disclosure. Figure 9In this scenario, UE (UE1) can operate in UE SBFD mode at symbols 910 and 920. For example, at symbol 910, the UE can simultaneously transmit at the UL subband (subband 914) and receive at the DL subband (subbands 912, 916). On the other hand, UE (UE1) can operate in HD mode at symbols 930 and 940. For example, at symbol 930, the UE can receive at the DL subband (subbands 932, 936) and may not transmit (the network can allocate UL subband 934 to another UE (UE2) for UL transmission). In these scenarios, the semi-static time for the SBFD symbols and the DL / UL subband network SBFD configuration may be insufficient to distinguish between the two different UE modes (i.e., distinguishing between UE HD mode with network SBFD mode and UE SBFD mode with network SBFD mode). Therefore, the network can further indicate to the UE whether the UE will operate in UE HD mode (with network SBFD mode) or UE SBFD mode (with network SBFD mode).

[0107] Further network indications can be beneficial because the UE may have different antenna configurations for the two modes. For example, when operating in UE HD mode, the UE may utilize the entire antenna array, while in UE SBFD mode, the UE may split the same antenna array into two separate arrays or panels. Additionally, in UE SBFD mode, the network may use two Transmit Configuration Indicator (TCI) states to configure the UE to accommodate paired DL and UL transmissions, which may differ from the TCI states used in UE HD mode. Operating parameters such as UL transmit power, MCS, and DL / UL beamforming may also vary between the two modes. Additionally, radio frequency (RF) tuning may need to be readjusted, especially when additional filters are used in SBFD mode to mitigate SI. In some examples, UE SBFD mode may require different configurations of subbands, frequency patterns, or guard bands, which may differ from the configurations used in UE HD mode.

[0108] In some respects, to indicate to the UE two different modes (i.e., UE SBFD mode or UE HD mode, where the network operates in SBFD mode), the network may provide a one-bit (or more-bit) indication when signaling to a UE with SBFD capability. One value of this indication may indicate that the UE operates in HD mode in SBFD resources, and another value of the indication may indicate that the UE operates in FD mode in SBFD resources. This indication may be useful where SI (Self-Switching Indicator) is important, and the UE can report the SI to the network and fall back to HD mode for more reliable communication. In some examples, the indication for mode switching may be delivered via one or more of the following: scheduled DCI, unscheduled DCI, group common (GC) DCI (e.g., GC DCI format 2_0), radio resource control (RRC) messages, or media access control (MAC)-control element (MAC-CE), thereby allowing dynamic or semi-persistent (SP) updates. Figure 10 Figure 1000 is an example illustrating indications of UE modes according to various aspects of this disclosure. Figure 10 In this configuration, the UE (UE1) can initially operate in UE SBFD mode. For example, the UE can simultaneously receive (via DL subbands 1012 and DL subband 1016) and transmit (via UL subband 1014) at symbol 1010. If the UE receives a bit indicating that it should operate in UE HD mode, the UE can fall back to UE HD mode (e.g., starting from symbol 1030). For example, at symbol 930, the UE (UE1) can receive via DL subbands (e.g., DL subbands 1032, 1036) and can also avoid transmitting in symbol 1030 (the network can allocate UL subband 1034 to another UE (UE2) for UL transmission).

[0109] In some aspects, the UE can perform instantaneous SI measurements (e.g., SI measurements triggered by an indication for the UE to operate in full-duplex mode in SBFD resources) and report the SI measurement results. In comparison, reporting via Channel State Information (CSI) can have intervals of 40 ms, which may be too long for some applications. Reporting of SI measurement results can be implemented in various ways. In some examples, bits indicating the SI can be added to the end of ACK / NACK feedback, for example, where "1" indicates the SI is above a certain threshold, and "0" indicates the SI is below that threshold. In some examples, if there are configured beam management (BM) reports to be transmitted at a certain interval (e.g., every 20 ms), the UE can add bits to the end of the most recently configured BM report to indicate the SI. In some examples, if configured BM reports are to be transmitted at a certain interval (e.g., every 20 ms), the UE can add BM metrics to the most recently configured BM report or modify existing BM metrics to reflect the level of SI. For example, a UE can report the signal-to-interference-plus-noise ratio (SINR) of Layer 1 (L1) signals with and without SI.

[0110] In some respects, indications of the two different modes of the UE (i.e., UE SBFD mode or UE HD mode, where the network operates in SBFD mode) can be based on semi-static network SBFD time indications. Figure 11 Figure 1100 is an example illustration of a UE mode according to various aspects of this disclosure. Figure 11 As shown, the network (e.g., a base station) may indicate auxiliary signaling 1140 (via indication 1130) on the indicated network SBFD symbol or time slot. This auxiliary signaling 1140 may indicate to the UE whether it should operate in UE HD mode or UE SBFD mode (where the network operates in SBFD mode). An example application of this might involve using predefined patterns, such as SPS combined with CG.

[0111] This indication can be implemented in various ways. In one configuration, it can be done via a bitmap on a per-symbol or per-slot basis. In another configuration, it can be done by defining a window specifying the start slot index and window length, thus indicating the duration of the mode. In yet another configuration, it can be done via a per-slot bitmap pattern that indicates which slots are operating in UE SBFD mode. For example, to indicate which slot has this pattern, it can be assumed that all downlink (D) or flexible (F) slots follow the same UE SBFD pattern, or that the network (e.g., the base station) can configure different patterns for different slots. To reduce overhead, the network (e.g., the base station) can configure a table of various patterns and indicate the index of the relevant pattern for each slot. These indications can be communicated to the UE via different channels, such as RRC messages, MAC-CE, or DCI. Figure 11 In the example, index "1" in 1142 of auxiliary signaling 1140 can instruct the UE to operate in SBFD mode for symbol 1110, meaning the UE can simultaneously transmit (e.g., at UL subband 1114) and receive (e.g., at DL subband 1112 and DL subband 1116) in symbol 1110. On the other hand, index "0" in 1144 of auxiliary signaling 1140 can instruct the UE to operate in HD mode for symbol 1120, meaning the UE can receive (e.g., at DL subband 1122 and DL subband 1126) in symbol 1120, but can choose not to transmit (the network can allocate UL subband 1124 to another UE (UE2) for UL transmission).

[0112] In some respects, in addition to instantaneous SI measurement and reporting, or as an alternative, the UE may perform periodic beam management (BM) taking into account the SI at the UE. For example, the UE may report the SI along with beam management reports. In some respects, the UE may receive a configuration that enables the UE to provide SI measurement and reporting. In some examples, for both UE FD operation and UESBFD operation, group-based beam reporting may be provided to report a pair of DL and UL beams to facilitate FD operation at the UE while minimizing the impact of the SI on the DL beam transmitted from its own UL.

[0113] In some examples, the UE may report the DL signal-to-interference-plus-noise ratio (SINR) in the BM report. SINR treats SI as an additional form of interference, where a new inferred measurement resource (IMR) is configured for SI resources and measurements. In some examples, the UE may report the DL reference signal received power (RSRP) in the BM report, such as when measured using the UE's UL beam (e.g., the network can transmit DL traffic, and the UE can receive it using the UL beam). This measurement reflects the quality of the UL beam, which helps establish a reliable UL link for FD operation. The selection of DL and UL beam pairs may be based on measurements of these combinations and the reporting of DL SINR and DL RSRP, such as when measured using the UE's UL beam.

[0114] In some respects, for beam selection and beam reporting purposes, the UE may report two assumptions in the CSI report. The first assumption may include that the SI is included as a channel quality indicator (CQI) of the measured interference, and the second assumption may include another CQI that has no effect on the SI.

[0115] Figure 12 This is a call flowchart 1200 illustrating a method of wireless communication according to various aspects of this disclosure. Various aspects are described in conjunction with UE 1202 and base station 1204. The aspects may be performed by UE 1202 or base station 1204 in the aggregation and / or by one or more components of base station 1204 (e.g., CU 110, DU 130 and / or RU 140).

[0116] like Figure 12 As shown, at 1206, UE 1202 can receive time and frequency configuration from base station 1204. In some examples, the time and frequency configuration can be an SBFD time and frequency configuration that allocates resources for communication with base station 1204 based on SBFD mode. For example, refer to... Figure 9 The SBFD time and frequency configuration can allocate resources for communicating with the base station (e.g., symbols 910 and 920).

[0117] At 1208, UE 1202 may receive a configuration grant (CG) for allocating uplink resources for uplink transmission. At 1210, UE 1202 may receive an SPS for allocating downlink resources for receiving downlink transmission. For example, refer to Figure 8 The UE can receive CGs (e.g., UE1 CG 802, 804) that allocate uplink resources and SPSs that allocate downlink resources (e.g., UE1 SPS 812, 814, 816, 818).

[0118] At 1212, UE 1202 can obtain a UE operating mode for the resource. This UE operating mode is either UE FD mode or UE HD mode. For example, refer to Figure 9 For symbols 910 and 920, the UE operating mode can be UE FD mode, meaning the UE can simultaneously transmit (e.g., at UL subbands 914 and 924) and receive (e.g., at DL subbands 912, 916, 922, and 926) at these symbols. For symbols 930 and 940, the UE operating mode can be UE HD mode, meaning the UE can perform either transmission or reception at these symbols, but not both. For example, UE1 can receive at symbol 930 (e.g., at DL subbands 932 and 936), but can choose not to transmit.

[0119] The UE operating mode for a resource can be obtained in various ways. In some examples, at 1214, UE 1202 may receive an indication of the UE operating mode from base station 1204. In some examples, UE 1202 may further receive secondary signaling (e.g., secondary signaling 1140) at 1216.

[0120] In some respects, UE 1202 may identify at 1218 a first set of times when the configured granted uplink resources overlap with the downlink resources of the SPS to obtain the UE operating mode. For example, refer to Figure 8 For times when uplink resources (e.g., UE1 CG 802) and downlink resources (e.g., UE1 SPS 812) overlap, the UE operating mode for these times can be UE FD mode.

[0121] In some respects, for example, when no UE operating mode is indicated, UE 1202 may set a default UE operating mode at 1220. In some examples, UE 1202 may set UE FD mode as the default UE operating mode.

[0122] At 1222, UE 1202 can perform SI measurements. In some examples, UE 1202 can perform SI measurements when the UE operating mode is UE FD mode.

[0123] At 1224, UE 1202 may send an SI indication, which may include an SI indication sent to base station 1204. The SI indication may be sent via, for example, a BM report (1226) or an ACK / NACK feedback report (1228).

[0124] At 1230, base station 1204 can send a configuration with group-based beam reports for periodic IMR used for SI measurements.

[0125] At 1232, UE 1202 may send a beam management (BM) report to base station 1204, which includes SI measurements based at least in part on periodic IMR.

[0126] At position 1234, UE 1202 may send a CSI report to base station 1204. In some examples, the CSI report may include two assumptions. The first assumption may be associated with a first CQI that includes SI as an interference source, and the second assumption may be associated with a second CQI that does not include SI as an interference source.

[0127] At 1236, UE 1202 can communicate with base station 1204 based on the UE operating mode and within the resources allocated to the UE.

[0128] Figure 13 This is a flowchart 1300 illustrating a method for wireless communication at a UE according to various aspects of this disclosure. The method can be performed by the UE. The UE can be UE 104, 350, 1202, or... Figure 21 The hardware implementation of device 2104. By enabling different modes of UE operation, these methods allow the UE to flexibly interact with various cell types and configurations to improve resource utilization efficiency. In some examples, by enabling the UE to measure SI and report the results to the network after an operating mode indication, these methods allow for rapid adjustment of operating parameters (such as antenna configuration and transmit power) to optimize its performance based on real-time conditions (such as traffic demand or signal interference), thereby ensuring communication reliability and maintaining optimal performance.

[0129] like Figure 13 As shown, at 1302, the UE can receive SBFD time and frequency configurations based on the SBFD mode to allocate resources for communication with a network entity. This network entity can be... Figure 1 The base station or base station component in the access network, or core network component (e.g., base station 102, 310, 1204; or Figure 21 The network entity 2102 in the specific hardware implementation). Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 Various aspects of the steps combined with flowchart 1300 are illustrated. For example, refer to... Figure 12 UE 1202 may receive at 1206 an SBFD time and frequency configuration based on SBFD mode to allocate resources for communication with network entities (base station 1204). In some respects, 1302 may be performed by operation mode component 198.

[0130] At 1304, the UE can obtain a UE operating mode for the resource. This UE operating mode can be either UE FD mode or UEHD mode. For example, refer to... Figure 12 UE 1202 can obtain the UE operating mode for the resource at 1212. This UE operating mode can be either UE FD mode or UE HD mode. (See reference...) Figure 9 For symbols 910 and 920, the UE operating mode can be UE FD mode, meaning the UE can simultaneously transmit (e.g., at UL subbands 914, 924) and receive (e.g., at DL subbands 912, 916, 922, 926) at these symbols. For symbols 930 and 940, the UE operating mode can be UE HD mode, meaning the UE can perform either transmission or reception at these symbols, but not both. For example, UE1 can receive at symbol 930 (e.g., at DL subbands 932 and 936), but can choose not to transmit. In some aspects, 1304 can be performed by operating mode component 198.

[0131] At point 1306, the UE can communicate with network entities within the resources allocated to the UE, based on its operating mode. For example, refer to... Figure 12 At 1236, UE 1202 can communicate with network entities (base station 1204) in resources allocated to the UE (e.g., symbols 910, 920, 930, 940) based on the UE's operating mode. In some aspects, 1306 can be performed by the operating mode component 198.

[0132] Figure 14 This is a flowchart 1400 illustrating a method for wireless communication at a UE according to various aspects of this disclosure. The method can be performed by the UE. The UE can be UE 104, 350, 1202, or... Figure 21 The hardware implementation of device 2104. By enabling different modes of UE operation, these methods allow the UE to flexibly interact with various cell types and configurations to improve resource utilization efficiency. In some examples, by enabling the UE to measure SI and report the results to the network after an operating mode indication, these methods allow for rapid adjustment of operating parameters (such as antenna configuration and transmit power) to optimize its performance based on real-time conditions (such as traffic demand or signal interference), thereby ensuring communication reliability and maintaining optimal performance.

[0133] like Figure 14 As shown, at 1402, the UE can receive SBFD time and frequency configurations based on the SBFD mode to allocate resources for communication with a network entity. This network entity can be... Figure 1The base station or base station component in the access network, or core network component (e.g., base station 102, 310, 1204; or Figure 21 The network entity 2102 in the specific hardware implementation). Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 Various aspects of the steps combined with flowchart 1400 are illustrated. For example, refer to... Figure 12 UE 1202 may receive at 1206 an SBFD time and frequency configuration based on SBFD mode to allocate resources for communication with network entities (base station 1204). In some respects, 1402 may be performed by operation mode component 198.

[0134] At point 1408, the UE can obtain a UE operating mode for the resource. This UE operating mode can be either UE FD mode or UEHD mode. For example, refer to... Figure 12 UE 1202 can obtain the UE operating mode for the resource at 1212. This UE operating mode can be either UE FD mode or UE HD mode. (See reference...) Figure 9 For symbols 910 and 920, the UE operating mode can be UE FD mode, meaning the UE can simultaneously transmit (e.g., at UL subbands 914, 924) and receive (e.g., at DL subbands 912, 916, 922, 926) at these symbols. For symbols 930 and 940, the UE operating mode can be UE HD mode, meaning the UE can perform either transmission or reception at these symbols, but not both. For example, UE1 can receive at symbol 930 (e.g., at DL subbands 932 and 936), but can choose not to transmit. In some aspects, 1408 can be performed by the operating mode component 198.

[0135] At point 1418, the UE can communicate with network entities within the resources allocated to the UE, based on its operating mode. For example, refer to... Figure 12 UE 1202 can communicate with network entities (base station 1204) at 1236 based on the UE operating mode, within resources allocated to the UE (e.g., symbols 910, 920, 930, 940). In some aspects, 1418 can be performed by operating mode component 198.

[0136] In some aspects, the UE may receive configuration approval at 1404 for allocating uplink resources for uplink transmission, and at 1406 receive an SPS for allocating downlink resources for receiving downlink transmission. To obtain a UE operating mode for the resources, the UE may identify a first set of times when the configured uplink resources overlap with the downlink resources of the SPS. To communicate with network entities, the UE may communicate with network entities based on a first set of one or more operating parameters associated with a first UE operating mode in the first set of times and a second set of one or more operating parameters associated with a second UE operating mode in a second set of one or more times. For example, refer to... Figure 12 UE 1202 may receive configuration approval at 1208 for allocating uplink resources for uplink transmission, and at 1210 receive SPS for allocating downlink resources for receiving downlink transmission. To obtain the UE operating mode for the resources (at 1212), UE 1202 may identify at 1218 a first set of times when the configured uplink resources overlap with the downlink resources of the SPS. For example, refer to... Figure 8 For occasions where uplink resources (e.g., UE1 CG 802) overlap with downlink resources (e.g., UE1 SPS 812), the UE operating mode for these occasions may be UE FD mode. UE 1202 may communicate with the network entity (base station 1204) at 1236 based on a first set of one or more operating parameters associated with a first UE operating mode in a first set of occasions (e.g., occasions with UE1 SPS 812 and UE1 CG 802) and a second set of one or more operating parameters associated with a second UE operating mode in a second set of occasions (e.g., occasions with UE1 SPS 814). In some aspects, 1404 and 1406 may be performed by operating mode component 198.

[0137] In some aspects, one or more operating parameters associated with the UE operating mode may include one or more of the following: DL MCS, UL MCS, DL beam for the UE, layer number for communicating with network entities, PMI, UL beam for the UE, UL PC parameters of the UE, or UL TA. For example, refer to Figure 12 One or more operating parameters associated with the UE operating mode (obtained at 1212) may include one or more of the following: DL MCS, UL MCS, DL beam for the UE, layer number for communicating with network entity (base station 1204), PMI, UL beam for UE 1202, UL PC parameters of UE 1202, or UL TA.

[0138] In some respects, to obtain the UE operating mode (at 1408), the UE may receive an indication of the UE operating mode for resources in the SBFD time and frequency configuration. For example, refer to Figure 11 and Figure 12 UE 1202 may receive an indication of the UE operating mode for resources in the SBFD time and frequency configuration (at 1206) (e.g., SBFD indication 1130).

[0139] In some respects, in order to obtain the UE operating mode (at 1408), the UE may set the default operating mode of the UE operating mode to UE FD mode in response to the SBFD time and frequency configuration not indicating the UE operating mode. For example, refer to Figure 12 UE1202 can set the default operating mode of UE to UE FD mode at 1220 in response to the SBFD time and frequency configuration not indicating the UE operating mode.

[0140] In some aspects, the indication of the UE operating mode may include a one-bit indicator, and this one-bit indicator may be included in one of the following: scheduled DCI, unscheduled DCI, GC DCI, RRC message, or MAC-CE. For example, refer to Figure 12 The indication of the UE operating mode (at 1214 or 1206) may include a one-bit indicator, and the one-bit indicator may be included in one of the following: scheduled DCI, unscheduled DCI, GC DCI, RRC message or MAC-CE.

[0141] In some aspects, in order to communicate with network entities (at 1418), the UE may apply a set of one or more operating parameters associated with the UE's operating mode, and communicate with the network entity based on this set of one or more operating parameters. The one or more operating parameters may include one or more of the following: DL MCS, UL MCS, DL beam for the UE, layer number for communicating with the network entity, PMI, UL beam for the UE, UL PC parameters of the UE, or UL TA. For example, refer to... Figure 12In order to communicate with the network entity (at 1236), UE 1202 may apply a set of one or more operating parameters associated with the UE operating mode (obtained at 1212), and communicate with the network entity (base station 1204) based on this set of one or more operating parameters (at 1236).

[0142] In some respects, the UE may perform an SI measurement at 1410 to obtain an SI indication in response to receiving an indication of the UE's operating mode in UE FD mode, and report the SI indication to the network entity at 1412. For example, refer to Figure 12 UE 1202 may perform SI measurements at 1222 in response to receiving an indication of UE operation mode in UE FD mode to obtain an SI indication, and report the SI indication to the network entity (base station 1204) at 1224. In some aspects, 1410 and 1412 may be performed by operation mode component 198.

[0143] In some respects, the SI indicator can be a one-bit indicator comparing the SI measurement to the SI threshold, and can be included in at least one of: an ACK / NACK feedback report, or a BM report. The SI indicator can be included in a bit at the end of a BM report, in a new BM metric, or in an existing BM metric within a BM report. For example, refer to... Figure 12 The SI indicator (at 1224) may be a one-bit indicator that indicates a comparison between the SI measurement and the SI threshold, and may be included in the ACK / NACK feedback report (1228) or the BM report (1226).

[0144] In some respects, to report the SI indication (at 1412), the UE can report the SI indication in the most recent BM report or the most recent ACK / NACK feedback report. For example, refer to Figure 12 UE 1202 can report the SI indication (at 1224) in the most recent BM report (1226) or the most recent ACK / NACK feedback report (1228).

[0145] In some respects, at 1414, the UE can receive a configuration with group-based beam reports having periodic IMRs for SI measurements; and send BM reports to network entities including SI measurements at least partially based on periodic IMRs. For example, refer to Figure 12UE 1202 can be configured at 1230 to receive a group-based beam report with periodic IMR for SI measurements; and at 1232 to send a BM report including SI measurements at least partially based on periodic IMR to the network entity (base station 1204). In some aspects, 1414 can be performed by the operation mode component 198.

[0146] In some aspects, the BM report may also include: a DL beam and a selected UL beam for selecting the UE FD mode in response to an indication of the UE operating mode indicating the UE FD mode. For example, refer to Figure 12 The BM report (at 1232) may also include: in response to an indication of the UE operating mode indicating the UE FD mode, the DL beam and the selected UL beam for the selection of the UE FD mode.

[0147] In some respects, the BM report may also include one or more of the following: the UE's DL SINR in response to an indication of the UE's operating mode indicating the UE's FD mode, wherein the SINR includes SI as interference; and the DLRSRP measured using the UE's UL beam.

[0149] In some respects, at point 1416, the UE can send a CSI report to the network entity. The CSI report may include two assumptions. The first assumption may be associated with a first CQI that includes SI as a source of interference, and the second assumption may be associated with a second CQI that does not include SI as a source of interference. For example, refer to... Figure 12 UE 1202 may send a CSI report to the network entity (base station 1204) at 1234. The CSI report may include two assumptions. The first assumption may be associated with a first CQI that includes SI as an interference source, and the second assumption may be associated with a second CQI that does not include SI as an interference source. In some aspects, 1416 may be performed by the operating mode component 198.

[0150] In some aspects, SBFD time and frequency configuration may include a semi-static network SBFD time and frequency indication that designates at least a portion of the resources as FD resources. To obtain the UE operating mode (at 1408), the UE can receive secondary signaling from the network entity via the FD resources; and based on the secondary signaling, obtain a UE mode indicator that indicates the UE operating mode corresponding to the FD resources or HD resources. For example, refer to... Figure 11 and Figure 12 The SBFD time and frequency configuration (at 1206) may include a semi-static network SBFD time and frequency indication (SBFD indication 1130) indicating at least a portion of the resource (e.g., symbol 1110) as an FD resource. In order to obtain the UE operating mode (at 1212), the UE 1202 may receive auxiliary signaling (auxiliary signaling 1140) from the network entity (base station 1204) at 1216 via the FD resource (e.g., symbol 1110); and obtain a UE mode indicator based on the auxiliary signaling, which indicates the UE operating mode corresponding to the FD resource or HD resource.

[0151] In some respects, the UE mode indicator may include one of the following: a bitmap indicator per symbol or per slot; a start index indicating the starting slot index and the length of the window to which the UE operating mode applies; or a style index identifying a bitmap style from a variety of bitmap styles in a pre-configuration table for each slot.

By enabling different modes of UE operation, these methods allow the UE to flexibly interact with various cell types and configurations to improve resource utilization efficiency. In some examples, by enabling the UE to measure SI and report the results to the network after an operating mode indication, these methods allow for rapid adjustment of operating parameters (such as antenna configuration and transmit power) to optimize its performance based on real-time conditions (such as traffic demand or signal interference), thereby ensuring communication reliability and maintaining optimal performance.

[0161] In some respects, to report the SI indication (at 1612), the UE can report the SI indication in the most recent BM report or the most recent ACK / NACK feedback report. For example, refer to Figure 12 UE 1202 can report the SI indication (at 1224) in the most recent BM report (1226) or the most recent ACK / NACK feedback report (1228).

[0162] In some respects, the UE can be configured to receive group-based beam reports with periodic IMRs at 1606 and send a BM report to the network entity at 1608 that includes measurements at least partially based on periodic IMRs.

The method can be performed by a network entity. The network entity can be... Figure 1 The base station or base station component in the access network, or core network component (e.g., base station 102, 310, 1204; or Figure 21(Network entity 2102 in the hardware implementation). By enabling different modes of UE operation, these methods allow the UE to interact flexibly with various cell types and configurations to improve resource utilization efficiency. In some examples, by enabling the UE to measure SI and report the results to the network after the operation mode indication, these methods allow for rapid adjustment of operating parameters (such as antenna configuration and transmit power) to optimize its performance based on real-time conditions (such as traffic demand or signal interference), thereby ensuring communication reliability and maintaining optimal performance.

[0168] like Figure 17 As shown, at 1702, the network entity can send an SBFD time and frequency configuration based on the SBFD mode to allocate resources for communication with the UE. The UE can be UE 104, 350, 1202, or... Figure 21 The hardware implementation of the device 2104.

Figure 12 The network entity (base station 1204) can send an SBFD time and frequency configuration at 1206 to allocate resources for communication with UE 1202 based on the SBFD mode. In some respects, 1702 can be performed by the operation mode component 199.

[0169] At 1704, a network entity can communicate with a UE within resources allocated to the UE based on the UE operating mode for those resources, where the UE operating mode is either UE FD mode or UE HD mode. For example, refer to... Figure 12 The network entity (base station 1204) can communicate with UE 1202 at location 1236 based on the resource-specific UE operating mode allocated to UE 1202 within the resources provided. This UE operating mode is either UE FD mode or UE HD mode. (See reference) Figure 9 For symbols 910 and 920, the UE operating mode can be UE FD mode, meaning the UE can simultaneously transmit (e.g., at UL subbands 914, 924) and receive (e.g., at DL subbands 912, 916, 922, 926) at these symbols. For symbols 930 and 940, the UE operating mode can be UE HD mode, meaning the UE can perform either transmission or reception at these symbols, but not both. For example, UE1 can receive at symbol 930 (e.g., at DL subbands 932 and 936), but can choose not to transmit. In some aspects, 1704 can be performed by operating mode component 199.

Figure 12 The network entity (base station 1204) can communicate with UE 1202 at location 1236 within the resources allocated to UE 1202, based on a resource-specific UE operating mode. This UE operating mode is either UE FD mode or UE HD mode. (See reference) Figure 9For symbols 910 and 920, the UE operating mode can be UE FD mode, meaning the UE can simultaneously transmit (e.g., at UL subbands 914, 924) and receive (e.g., at DL subbands 912, 916, 922, 926) at these symbols. For symbols 930 and 940, the UE operating mode can be UE HD mode, meaning the UE can perform either transmission or reception at these symbols, but not both. For example, UE1 can receive at symbol 930 (e.g., at DL subbands 932 and 936), but can choose not to transmit. In some aspects, 1820 can be performed by operating mode component 199.

[0173] In some aspects, a network entity may send a configuration grant at 1804 to allocate uplink resources for uplink transmission, and send an SPS at 1806 to allocate downlink resources for receiving downlink transmission. The UE operating mode for the resources may be based on a first set of times when the configured uplink resources overlap with the downlink resources of the SPS. To communicate with the UE, the network entity may communicate with the UE based on a first set of one or more operating parameters associated with a first UE operating mode in the first set of times and a second set of one or more operating parameters associated with a second UE operating mode in a second set of times.

A network entity (base station 1204) can communicate with UE 1202 at 1236 based on a first set of one or more operating parameters associated with a first UE operating mode in a first set of times (e.g., times with UE1 SPS 812 and UE1 CG 802) and a second set of one or more operating parameters associated with a second UE operating mode in a second set of times (e.g., times with UE1 SPS 814).

[0184] In some respects, at point 1818, the network entity can receive a CSI report from the UE. The CSI report may include two assumptions. The first assumption may be associated with a first CQI that includes SI as a source of interference, and the second assumption may be associated with a second CQI that does not include SI as a source of interference. For example, refer to... Figure 12 The network entity (base station 1204) can receive a CSI report from UE 1202 at 1234. The CSI report may include two assumptions.

For example, refer to Figure 12 The selected DL beam and the selected UL beam (in the BM report at 1232) can be based on DL SINR and DL RSRP measured using the UE UL beam.

[0199] In some respects, at 2008, network entities could receive CSI reports from the UE. The CSI report could include two assumptions. The first assumption could be associated with a first CQI that includes SI as a source of interference, and the second assumption could be associated with a second CQI that does not include SI as a source of interference. For example, refer to... Figure 12 The network entity (base station 1204) can receive a CSI report from UE 1202 at 1234. The CSI report may include two assumptions. A first assumption may be associated with a first CQI that includes SI as an interference source, and a second assumption may be associated with a second CQI that does not include SI as an interference source.
