[0022] This disclosure provides apparatus, methods, processing systems, and computer-readable media for generating power clearance reports for transmission using full-duplex operation. In a wireless network system, a user equipment (UE) may, for example, use a Media Access Control (MAC-CE) element transmitted on the Physical Uplink Shared Channel (PUSCH) to transmit a power clearance report (PHR) to a network entity (e.g., a base station). The network entity may use these reports within its packet scheduler and link adaptation algorithm. The packet scheduler is responsible for identifying the number of resource blocks to allocate to the PUSCH, while link adaptation is responsible for identifying the modulation and decoding scheme (MCS). In some cases, if the UE is reporting low power clearance (PH), it may be necessary to limit the number of allocated resource blocks or the allocated MCS.

[0023] PHR can also be used in other areas of radio resource management. The network can use PHR to calculate path loss to the UE. These path loss results can then be used to enable or disable specific functionalities. For example, when path loss is low, uplink carrier aggregation can be used to configure the UE, and if path loss becomes high, this configuration can then be released. That is, when path loss is high, the UE can benefit from concentrating its uplink transmit power on a single carrier rather than multiple carriers.

[0024] In some aspects, the UE can be configured for half-duplex (HD) operation and / or full-duplex (FD) operation. In half-duplex operation, the UE can transmit at a first power, and for full-duplex operation, the UE can transmit at different power levels. For example, for transmission using full-duplex operation, uplink power control includes additional considerations such as network-side cross-link interference (CLI) and self-interference (SI). Therefore, uplink power control for half-duplex and full-duplex operations can be different. In some transmission instances, the uplink transmission power in full-duplex operation can be increased to address network-side self-interference. In other transmission instances, the uplink transmission power in full-duplex operation can be decreased to reduce CLI. Therefore, full-duplex operation has different considerations and thus a different PHR compared to half-duplex operation.

[0025] In full-duplex networks, both half-duplex and full-duplex operations are permitted. However, the PHR (Passive Message) is calculated and transmitted based on half-duplex operations, resulting in insufficient PHR information for full-duplex operations being calculated and transmitted to the network (e.g., base stations). There are technical issues in determining the PH (Probability of Change) value for different transmission duplex types (e.g., half-duplex and full-duplex). This technical issue can lead to inaccurate PH values ​​provided to the network, resulting in the network incorrectly calculating path loss to the UE, incorrectly allocating resource blocks to the PUSCH, or incorrectly identifying the MCS (Multi-Channel System).

[0026] The technical solutions to the aforementioned problems include: accurately determining and delivering power levels (PHs) for the corresponding duplex and transmission types, and further transmitting corresponding power HRs (PHRs) to the network with indications of the duplex and transmission types. These and other technical benefits include enabling the network to effectively manage resources and allocate appropriate power levels to the UE for full-duplex operation. Additionally, by knowing the power headroom for each UE for full-duplex operation, the network can make informed decisions regarding resource allocation and power control, thereby ensuring efficient and reliable communication for full-duplex operation. Furthermore, the aspects described herein also provide the technical benefits of better UE power management, as the UE can determine and deliver PHs for a specific duplex type, which the network can then utilize to improve the allocation of resource blocks, etc., for communication with the UE.

[0027] An introduction to wireless communication networks

[0028] The techniques and methods described herein can be used in a variety of wireless communication networks. Although aspects herein may be described using terms commonly associated with 3G, 4G, 5G, 6G, and / or other generations of wireless technologies, aspects of this disclosure are equally applicable to other communication systems and standards not explicitly mentioned herein.

[0029] Figure 1 An example of a wireless communication network 100 in which the aspects described herein can be implemented is depicted.

[0030] Generally, wireless communication network 100 includes various network entities (alternatively, network elements or network nodes). Network entities are typically communication devices and / or communication functions performed by communication devices (e.g., user equipment (UE), base station (BS), components of a BS, servers, etc.). Because such communication devices are part of wireless communication network 100 and facilitate wireless communication, they may be referred to as wireless communication devices. For example, various functions of the network and various devices associated with and interacting with the network may be considered network entities. Furthermore, wireless communication network 100 includes terrestrial and non-terrestrial aspects (also referred to herein as non-terrestrial network entities). Terrestrial aspects include terrestrial network entities such as terrestrial network entities (e.g., BS 102), and non-terrestrial aspects include satellite 140 and aircraft. These non-terrestrial aspects may include onboard network entities (e.g., one or more BSs) capable of communicating with other network elements (e.g., terrestrial BSs) and UEs.

[0031] In the depicted example, wireless communication network 100 includes BS 102, UE 104 and one or more core networks (such as Evolved Packet Core (EPC) 160 and 5G Core (5GC) network 190) that interoperate to provide communication services over various communication links, including wired and wireless links.

[0032] Figure 1Various example UE 104s are described, which may more generally 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, cameras, game consoles, tablet computers, smart devices, wearable devices, vehicles, electricity meters, air pumps, large or small kitchen appliances, healthcare devices, implants, sensors / actuators, displays, Internet of Things (IoT) devices, always-on (AON) devices, edge processing devices, data centers, or other similar devices. UE 104 may also be more generally referred to as mobile devices, wireless devices, stations, mobile stations, subscriber stations, mobile subscriber stations, mobile units, subscriber units, wireless units, remote units, remote devices, access terminals, mobile terminals, wireless terminals, remote terminals, mobile phones, and others.

[0033] BS 102 communicates wirelessly with UE 104 via communication link 120 (e.g., sending or receiving signals to or from UE 104). Communication link 120 between BS 102 and UE 104 may include uplink (UL) transmission (also referred to as reverse link) from UE 104 to BS 102 and / or downlink (DL) transmission (also referred to as forward link) transmission from BS 102 to UE 104. In various aspects, communication link 120 may utilize multiple-input multiple-output (MIMO) antenna technologies, including spatial multiplexing, beamforming, and / or transmit diversity.

[0034] BS 102 may typically include: NodeB, enhanced NodeB (eNB), next-generation enhanced NodeB (ng-eNB), next-generation NodeB (gNB or gNodeB), access point, transceiver base station, radio base station, radio transceiver, transceiver functionality, transmit / receive point, and / or others. Each of BS 102 provides communication coverage for a corresponding coverage area 110, which may sometimes be referred to as a cell, and in some cases may overlap (e.g., a small cell 102' may have a coverage area 110' that overlaps with the coverage area 110 of a macro cell). For example, BS may provide communication coverage for macro cells (covering a relatively large geographic area), pico cells (covering a relatively small geographic area, such as a stadium), femtocells (covering a relatively small geographic area (e.g., a home)), and / or other types of cells.

[0035] Generally, a cell can refer to a portion, partition, or segment of wireless communication coverage served by network entities within a wireless communication network. A cell can have geographical characteristics (such as a geographical coverage area) and radio frequency characteristics (such as time and / or frequency resources dedicated to the cell). For example, multiple cells employing different frequency resources (e.g., bandwidth portions) and / or different time resources can cover a specific geographical coverage area. As another example, a single cell can cover a specific geographical coverage area. In some contexts (e.g., carrier aggregation scenarios and / or multi-connectivity scenarios), the terms "cell" or "serving cell" can refer to or correspond to a specific carrier frequency (e.g., component carrier) used for wireless communication, and "cell group" can refer to or correspond to multiple carriers used for wireless communication. As an example, in a carrier aggregation scenario, a UE can communicate on multiple component carriers corresponding to multiple (serving) cells in the same cell group, and in a multi-connectivity (e.g., dual-connectivity) scenario, a UE can communicate on multiple component carriers corresponding to multiple cell groups.

[0036] Although BS 102 is described as a single communication device in various aspects, it can be implemented in a variety of configurations. For example, to give a few examples, one or more components of the base station can be decomposed, including a central unit (CU), one or more distributed units (DU), one or more radio units (RU), a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC. In another example, various aspects of the base station can be virtualized. More generally, a base station (e.g., BS 102) can include components located at a single physical location or components located at various physical locations. In examples where the base station includes components located at various physical locations, the various components can each perform functions, such that the various components collectively achieve functionality similar to a base station located at a single physical location. In some aspects, a base station including components located at various physical locations can be referred to as a decomposed radio access network architecture (such as an open RAN (O-RAN) or virtualized RAN (VRAN) architecture). Figure 2 An example decomposed base station architecture is depicted and described.

[0037] Different BSs 102 within the wireless communication network 100 can also be configured to support different radio access technologies (such as 3G, 4G, and / or 5G). For example, a BS 102 configured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) can interface with EPC 160 via a first backhaul link 132 (e.g., S1 interface). A BS 102 configured for 5G (e.g., 5G NR or Next Generation RAN (NG-RAN)) can interface with 5GC 190 via a second backhaul link 184. BSs 102 can communicate directly or indirectly (e.g., via EPC 160 or 5GC 190) on a third backhaul link 134 (e.g., X2 interface), which can be wired or wireless.

[0038] Wireless communication network 100 can subdivide the electromagnetic spectrum into various categories, bands, channels, or other characteristics. In some aspects, subdivision is provided based on wavelength and frequency, where frequency may also be referred to as carrier, subcarrier, channel, tone, or subband. For example, 3GPP currently defines frequency range 1 (FR1) as including 410MHz to 7125MHz, which is often (interchangeably) referred to as “sub-6GHz”. Similarly, 3GPP currently defines frequency range 2 (FR2) as including 24,250MHz to 71,000MHz, which is sometimes (interchangeably) referred to as “millimeter wave” (“mmW” or “mmWave”). In some cases, FR2 can be further defined according to subranges (such as a first subrange FR2-1 including 24,250MHz to 52,600MHz and a second subrange FR2-2 including 52,600MHz to 71,000MHz). Base stations configured to communicate using mmWave / near-mmWave radio bands (e.g., mmWave base stations such as BS 180) can utilize beamforming (e.g., 182) with UEs (e.g., 104) to improve path loss and range.

[0039] The communication link 120 between BS 102 and, for example, UE 104 can be via one or more carriers, which may have different bandwidths (e.g., 5MHz, 10MHz, 15MHz, 20MHz, 100MHz, 400MHz and / or other MHz) and may be aggregated in various ways. The carriers may be adjacent to each other or may not be adjacent to each other. The allocation of carriers may be asymmetric for DL ​​and UL (e.g., more or fewer carriers may be allocated to DL compared to UL).

[0040] Compared to lower-frequency communication, communication using higher frequency bands may have higher path loss and shorter range. Therefore, some base stations (e.g., Figure 1 The beamforming 182 of the BS 180 (180) with the UE 104 can be used to improve path loss and range. For example, the BS 180 and UE 104 may each include multiple antennas, such as antenna elements, antenna panels, and / or antenna arrays, to facilitate beamforming. In some cases, the BS 180 may transmit beamformed signals to the UE 104 in one or more transmit directions 182''. The UE 104 may receive beamformed signals from the BS 180 in one or more receive directions 182''. The UE 104 may also transmit beamformed signals to the BS 180 in one or more transmit directions 182''. The BS 180 may also receive beamformed signals from the UE 104 in one or more receive directions 182''. The BS 180 and UE 104 may then perform beamforming training to determine the optimal receive and transmit directions for each of the BS 180 and UE 104. It is worth noting that the transmit and receive directions of the BS 180 may be the same or different. Similarly, the sending and receiving directions of UE 104 can be the same or different.

[0041] The wireless communication network 100 also includes a Wi-Fi AP 150 that communicates with a Wi-Fi station (STA) 152 via a communication link 154 in, for example, unlicensed spectrum in 2.4 GHz and / or 5 GHz.

[0042] Some UEs 104 may use device-to-device (D2D) communication link 158 to communicate with each other. The D2D communication link 158 may use one or more sidelink channels, such as physical sidelink broadcast channel (PSBCH), physical sidelink discovery channel (PSDCH), physical sidelink shared channel (PSSCH), physical sidelink control channel (PSCCH), and / or physical sidelink feedback channel (PSFCH).

[0043] EPC 160 may include various functional components, including: Mobility Management Entity (MME) 162, other MMEs 164, Serving Gateway 166, Multimedia Broadcast Multicast Service (MBMS) Gateway 168, Broadcast Multicast Service Center (BM-SC) 170, and / or Packet Data Network (PDN) Gateway 172, as in the illustrated example. MME 162 may communicate with Home Subscriber Server (HSS) 174. MME 162 is the control node that handles signaling between UE 104 and EPC 160. Generally, MME 162 provides bearer and connectivity management.

[0044] Generally, user Internet Protocol (IP) packets are transmitted through Serving Gateway 166, which is itself connected to PDN Gateway 172. PDN Gateway 172 provides UE IP address allocation and other functions. PDN Gateway 172 and BM-SC 170 are connected to IP services 176, which may include, for example, the Internet, intranets, IP Multimedia Subsystem (IMS), packet-switched (PS) streaming services, and / or other IP services.

[0045] The BM-SC 170 provides functionality for MBMS user service dispatch and delivery. The BM-SC 170 can serve as an entry point for content provider MBMS transmissions, authorize and initiate MBMS bearer services within a Public Land Mobile Network (PLMN), and / or schedule MBMS transmissions. The MBMS Gateway 168 can distribute MBMS services to BS 102 within a Broadcast-Specific Service Single Frequency Network (MBSFN) area, and / or be responsible for session management (start / stop) and collecting eMBMS-related billing information.

[0046] 5GC 190 may include various functional components, including: Access and Mobility Management Function (AMF) 192, other AMFs 193, Session Management Function (SMF) 194, and User Plane Function (UPF) 195. AMF 192 may communicate with Unified Data Management (UDM) 196.

[0047] AMF 192 is the control node that handles signaling between UE 104 and 5GC 190. AMF 192 provides services such as Quality of Service (QoS) flow and session management.

[0048] Internet Protocol (IP) packets are transmitted via UPF 195, which connects to IP service 197 and provides UE IP address allocation and other functions for 5GC 190. IP service 197 may include, for example, the Internet, intranet, IMS, PS streaming service, and / or other IP services.

[0049] In various aspects, to give a few examples, network entities or network nodes can be implemented as aggregated base stations, decomposed base stations, components of base stations, integrated access and backhaul (IAB) nodes, relay nodes, and sidelink nodes.

[0050] Figure 2An example decomposed base station 200 architecture is depicted. The decomposed base station 200 architecture may include one or more central units (CUs) 210, which may communicate directly with the core network 220 via a backhaul link, or indirectly with the core network 220 through one or more decomposed base station units, such as a near real-time (near-RT) RAN Intelligent Controller (RIC) 225 via an E2 link, or a non-real-time (non-RT) RIC 215 associated with a Service Management and Orchestration (SMO) framework 205, or both. CUs 210 may communicate with one or more distributed units (DUs) 230 via corresponding midhaul links (such as F1 interfaces). DUs 230 may communicate with one or more radio units (RUs) 240 via corresponding fronthaul links. RUs 240 may communicate with a corresponding UE 104 via one or more radio frequency (RF) access links. In some specific implementations, UE 104 may be served simultaneously by multiple RUs 240.

[0051] Each unit in a cell (e.g., CU 210, DU 230, RU 240, and near-RT RIC 225, non-RT RIC 215, and SMO frame 205) may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the cells, or an associated processor or controller that provides instructions to the cell's communication interface, may be configured to communicate with one or more other cells via the transmission medium. For example, these cells may include a wired interface configured to receive signals or transmit signals to one or more other cells via a wired transmission medium. Additionally or alternatively, a cell may include a wireless interface that may include a receiver, transmitter, or transceiver (such as a radio frequency (RF) transceiver) configured to receive signals on a wireless transmission medium or transmit signals to one or more other cells, or both.

[0052] In some aspects, CU 210 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 communicate signaling with other control functions hosted by CU 210. CU 210 can be configured to handle user plane functions (e.g., Central Unit-User Plane (CU-UP)), control plane functions (e.g., Central Unit-Control Plane (CU-CP)), or combinations thereof. In some implementations, CU 210 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, CU-UP units can communicate bidirectionally with CU-CP units via an interface such as an E1 interface. CU 210 can be implemented to communicate with DU 230 for network control and signaling purposes, as needed.

[0053] DU 230 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RU 240s. In some aspects, DU 230 may at least partially host one or more of the Radio Link Control (RLC) layer, Medium 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 the 3rd Generation Partnership Project (3GPP). In some aspects, DU 230 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 230 or with control functions hosted by CU 210.

[0054] Lower-layer functionality can be implemented by one or more RU 240s. In some deployments, an RU240 controlled by a DU 230 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, or Physical Random Access Channel (PRACH) extraction and filtering, or both, at least in part based on functional decomposition (such as lower-layer functional decomposition). In such architectures, the RU 240 may be implemented to handle over-the-air (OTA) communications with one or more UE 104s. In some specific implementations, the real-time and non-real-time aspects of control plane and user plane communications with the RU 240 may be controlled by the corresponding DU 230. In some scenarios, this configuration enables the implementation of the DU 230 and CU 210 in cloud-based RAN architectures (such as vRAN architectures).

[0055] SMO framework 205 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, SMO framework 205 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 205 can be configured to interact with cloud computing platforms such as Open Cloud (O-Cloud) 290 to perform network element lifecycle management (such as instantiating virtualized network elements) via cloud computing platform interfaces such as the O2 interface. Such virtualized network elements may include, but are not limited to, CU 210, DU 230, RU 240, and near-RT RIC 225. In some specific implementations, SMO framework 205 may communicate with the hardware aspects of the 4G RAN (such as Open eNB (O-eNB) 211) via the O1 interface. Additionally, in some implementations, the SMO framework 205 may communicate directly with one or more DU 230s and / or one or more RU 240s via the O1 interface. The SMO framework 205 may also include a non-RT RIC 215 configured to support the functionality of the SMO framework 205.

[0056] The non-RT RIC 215 can be configured to include logical functions that enable non-real-time control and optimization of RAN elements and resources, including artificial intelligence / machine learning (AI / ML) workflows for model training and updates, or policy-based guidance for applications / features in the near-RT RIC 225. The non-RT RIC 215 can be coupled to or communicate with the near-RT RIC 225, such as via an A1 interface. The near-RT RIC 225 can be configured to include logical functions that enable near real-time control and optimization of RAN elements and resources via an interface, such as via an E2 interface, through data collection and actions, connecting one or more CU 210s, one or more DU 230s, or both, and O-eNBs to the near-RT RIC 225.

[0057] In some implementations, to generate AI / ML models to be deployed in the near-RT RIC 225, the non-RT RIC 215 may receive parameters or external enrichment information from an external server. This information can be utilized by the near-RT RIC 225 and may be received from non-network data sources or network functions at the SMO framework 205 or the non-RT RIC 215. In some examples, the non-RT RIC 215 or the near-RT RIC 225 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 215 may monitor long-term trends and patterns in performance and employ AI / ML models to perform corrective actions via the SMO framework 205 (such as reconfiguration via O1) or by creating RAN management policies (such as A1 policies).

[0058] Figure 3 Various aspects of examples BS 102 and UE 104 are described.

[0059] Generally, BS 102 includes various processors (e.g., 318, 320, 330, 338, and 340), antennas 334a to 334t (collectively referred to as 334), transceivers 332a to 332t (collectively referred to as 332) including modulators and demodulators, and other aspects that enable the wireless transmission of data (e.g., data source 312) and the wireless reception of data (e.g., data sink 314). For example, BS 102 can transmit and receive data between BS 102 and UE 104. BS 102 includes a controller / processor 340 that can be configured to implement the various wireless communication-related functions described herein.

[0060] Generally, UE 104 includes various processors (e.g., 358, 364, 366, 370, and 380), antennas 352a to 352r (collectively referred to as 352), transceivers 354a to 354r (collectively referred to as 354) including modulators and demodulators, and other aspects that enable the wireless transmission of data (e.g., retrieval from data source 362) and the wireless reception of data (e.g., provision to data sink 360). UE 104 includes a controller / processor 380 that can be configured to implement the various wireless communication-related functions described herein.

[0061] Regarding example downlink transmission, BS 102 includes a transmission processor 320 that can receive data from data source 312 and control information from controller / processor 340. This control information may be for a Physical Broadcast Channel (PBCH), Physical Control Format Indicator Channel (PCFICH), Physical Hybrid Automatic Repeat Request (HARQ) Indicator Channel (PHICH), Physical Downlink Control Channel (PDCCH), Group Common PDCCH (GC PDCCH), and / or others. In some examples, this data may be for a Physical Downlink Shared Channel (PDSCH).

[0062] The transmitter processor 320 can process data and control information (e.g., encoding and symbol mapping) to obtain data symbols and control symbols, respectively. The transmitter processor 320 can also generate reference symbols (such as those for the primary synchronization signal (PSS), secondary synchronization signal (SSS), PBCH demodulation reference signal (DMRS), and channel state information reference signal (CSI-RS)).

[0063] The transmit (TX) multiple-input multiple-output (MIMO) processor 330 can perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, and / or reference symbols where applicable, and can provide the output symbol stream to the modulators (MODs) in transceivers 332a to 332t. Each modulator in transceivers 332a to 332t can process the corresponding output symbol stream to obtain an output sample stream. Each modulator can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The downlink signal from the modulators in transceivers 332a to 332t can be transmitted via antennas 334a to 334t, respectively.

[0064] To receive downlink transmissions, UE 104 includes antennas 352a to 352r that receive downlink signals from BS 102 and provide the received signals to demodulators (DEMODs) in transceivers 354a to 354r, respectively. Each demodulator in transceivers 354a to 354r can adjust (e.g., filter, amplify, down-convert, and digitize) the corresponding received signal to obtain an input sample. Each demodulator can further process the input sample to obtain the received symbols.

[0065] The RX MIMO detector 356 acquires received symbols from all demodulators in transceivers 354a to 354r, performs MIMO detection on the received symbols where applicable, and provides the detected symbols. The receive processor 358 processes the detected symbols (e.g., demodulation, deinterleaving, and decoding), provides the decoded data of UE 104 to data sink 360, and provides the decoded control information to controller / processor 380.

[0066] Regarding example uplink transmission, UE 104 also includes a transmit processor 364 that receives and processes data from data source 362 (e.g., for PUSCH) and control information from controller / processor 380 (e.g., for Physical Uplink Control Channel (PUCCH)). Transmit processor 364 may also generate reference symbols for reference signals (e.g., for Sounding Reference Signal (SRS)). Symbols from transmit processor 364 may be pre-decoded by TX MIMO processor 366 where applicable, further processed by modulators in transceivers 354a to 354r (e.g., for SC-FDM), and transmitted to BS 102.

[0067] At BS 102, uplink signals from UE 104 can be received by antennas 334a to 334t, processed by demodulators in transceivers 332a to 332t, detected where applicable by RX MIMO detector 336, and further processed by receiver processor 338 to obtain decoded data and control information transmitted by UE 104. Receiver processor 338 can provide the decoded data to data sink 314 and the decoded control information to controller / processor 340.

[0068] Memory 342 and memory 382 can store data and program code for BS 102 and UE 104, respectively.

[0069] Scheduler 344 can schedule UE to send data on the downlink and / or uplink.

[0070] In various respects, BS 102 can be described as transmitting and receiving various types of data associated with the methods described herein. In these contexts, “transmitting” can refer to various mechanisms that output data, such as from data source 312, scheduler 344, memory 342, transmit processor 320, controller / processor 340, TX MIMO processor 330, transceivers 332a to 332t, antennas 334a to 334t, and / or other aspects described herein. Similarly, “receiving” can refer to various mechanisms that acquire data, such as from antennas 334a to 334t, transceivers 332a to 332t, RX MIMO detector 336, controller / processor 340, receive processor 338, scheduler 344, memory 342, and / or other aspects described herein.

[0071] In various respects, UE 104 can also be described as transmitting and receiving various types of data associated with the methods described herein. In these contexts, “transmitting” can refer to various mechanisms that output data, such as from data source 362, memory 382, ​​transmit processor 364, controller / processor 380, TX MIMO processor 366, transceivers 354a to 354t, antennas 352a to 352t, and / or other aspects described herein. Similarly, “receiving” can refer to various mechanisms that acquire data, such as from antennas 352a to 352t, transceivers 354a to 354t, RX MIMO detector 356, controller / processor 380, receive processor 358, memory 382, ​​and / or other aspects described herein.

[0072] In some respects, the processor can be configured to perform various operations (such as those associated with the methods described herein) and to send (output) data to or receive data from another interface configured to send or receive data, respectively.

[0073] In various aspects, artificial intelligence (AI) processors 318 and 370 may perform AI processing for BS 102 and / or UE 104, respectively. AI processor 318 may include AI accelerator hardware or circuitry, such as one or more neural processing units (NPUs), one or more neural network processors, one or more tensor processors, one or more deep learning processors, etc. AI processor 370 may similarly include AI accelerator hardware or circuitry. As an example, AI processor 370 may perform AI-based beam management, AI-based channel state feedback (CSF), AI-based antenna tuning, and / or AI-based positioning (e.g., Global Navigation Satellite System (GNSS) positioning). In some cases, AI processor 318 may use hardware-accelerated AI inference and / or AI training to process feedback (e.g., CSF) from UE 104. AI processor 318 may, for example, use hardware-accelerated AI inference associated with the CSF to decode compressed CSF from UE 104. In some cases, AI processor 318 may perform certain RAN-based functions, including, for example, network planning, network performance management, energy-efficient network operation, etc.

[0074] Figure 4A , Figure 4B , Figure 4C and Figure 4D Describes the use of wireless communication networks (such as Figure 1 All aspects of the data structure of the wireless communication network 100.

[0075] Specifically, Figure 4A Figure 400 is an example of the first subframe within a 5G (e.g., 5G NR) frame structure. Figure 4B Figure 430 illustrates an example of a DL channel within a 5G subframe. Figure 4C Figure 450 illustrates an example of the second subframe within a 5G frame structure, and Figure 4D Figure 480 illustrates an example of a UL channel within a 5G subframe.

[0076] Wireless communication systems can utilize Orthogonal Frequency Division Multiplexing (OFDM) with a cyclic prefix (CP) on both the uplink and downlink. Such systems can also support half-duplex operation using Time Division Duplex (TDD). OFDM and Single-Carrier Frequency Division Multiplexing (SC-FDM) will (e.g., as...) Figure 4B and Figure 4D The system bandwidth (as depicted in the text) is divided into multiple orthogonal subcarriers. Each subcarrier can be modulated with data. Modulation symbols can be transmitted in the frequency domain using OFDM and / or in the time domain using SC-FDM.

[0077] Wireless communication frame structures can be frequency division duplex (FDD), where for a specific set of subcarriers, subframes within that set are dedicated to either deep (DL) or ultra-low (UL). Wireless communication frame structures can also be time division duplex (TDD), where for a specific set of subcarriers, subframes within that set are dedicated to both DL and UL.

[0078] exist Figure 4A and Figure 4C In this example, the wireless communication frame structure is TDD, where D stands for DL, U for UL, and X is flexibly used between DL and UL. The UE can be configured using a slot format (dynamically configured via DL control information (DCI) or semi-statically / statically configured via Radio Resource Control (RRC) signaling) through the received Slot Format Indicator (SFI). In the depicted example, a 10ms frame is divided into 10 equal-sized 1ms subframes. Each subframe may include one or more slots. In some examples, each slot may include 12 or 14 symbols, depending on the Cyclic Prefix (CP) type (e.g., 12 symbols per slot for extended CP, or 14 symbols per slot for regular CP). Subframes may also include micro-slots, which typically have fewer symbols than the entire slot. Other wireless communication technologies may have different frame structures and / or different channels.

[0079] In some respects, the number of time slots within a subframe (e.g., the time slot duration within a subframe) is based on a parameter set that defines the frequency-domain subcarrier spacing and symbol duration, as further described herein. In some respects, given a parameter set μ, each subframe has 2 μ The number of time slots is 1. Therefore, parameter sets (µ) 0 through 6 allow for 1, 2, 4, 8, 16, 32, and 64 time slots per subframe, respectively. In some cases, extended CP (e.g., 12 symbols per time slot) can be used with specific parameter sets; for example, parameter set 2 allows for 4 time slots per subframe. Subcarrier spacing and symbol length / duration are functions of the parameter set. The subcarrier spacing can be equal to... kHz, where μ is the parameter set from 0 to 6. As an example, the parameter set... Corresponding to a subcarrier spacing of 15 kHz, and the parameter set This corresponds to a subcarrier spacing of 960 kHz. Symbol length / duration is negatively correlated with subcarrier spacing. Figure 4A , Figure 4B , Figure 4C and Figure 4D It provides a slot format with 14 symbols per slot (e.g., regular CP) and a parameter set with 4 slots per subframe. An example. In this case, the slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs.

[0080] like Figure 4A , Figure 4B , Figure 4C and Figure 4D As depicted, the resource grid can be used to represent the frame structure. Each time slot includes a resource block (RB) (also known as a physical RB (PRB)) extending for, for example, 12 consecutive subcarriers. The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme, including, for example, quadrature phase shift keying (QPSK) or quadrature amplitude modulation (QAM).

[0081] like Figure 4A As illustrated in the example, some REs in the RE carry information for the UE (e.g., Figure 1 and Figure 3 The reference (pilot) signal (RS) for the UE (104) may include a demodulation RS (DMRS) and / or a channel state information reference signal (CSI-RS) for channel estimation at the UE. The RS may also include a beam measurement RS (BRS), a beam refinement RS (BRRS), and / or a phase tracking RS (PT-RS).

[0082] Figure 4B Examples 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), each CCE comprising, for example, nine RE groups (REGs), each REG comprising, for example, four consecutive REs in an OFDM symbol.

[0083] The Primary Synchronization Signal (PSS) can be located within symbol 2 of a specific subframe of the frame. The PSS is generated by the UE (e.g., Figure 1 and Figure 3 104) is used to determine subframe / symbol timing and physical layer identifier.

[0084] The Supplemental Synchronization Signal (SSS) can be located in 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.

[0085] Based on the Physical Layer Identifier and 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 aforementioned DMRS. 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. The MIB provides the System Frame Number (SFN) and the number of Restricted Frames (RBs) in the system bandwidth. The Physical Downlink Shared Channel (PDSCH) carries user data, broadcast system information (such as System Information Blocks (SIBs)) not transmitted via the PBCH, and / or paging messages.

[0086] like Figure 4C As illustrated, some REs in the REs carry DMRS for channel estimation at the base station (indicated as R for a particular configuration, but other DMRS configurations are possible). The UE can transmit DMRS for PUCCH and DMRS for PUSCH. PUSCH DMRS can be transmitted, for example, in the first or second symbol before the PUSCH. PUCCH DMRS can be transmitted in different configurations depending on whether a short or long PUCCH is being transmitted and depending on the specific PUCCH format used. UE104 can transmit a Sounding Reference Signal (SRS). SRS can be transmitted, for example, in the last symbol of a subframe. SRS can have a comb structure, and the UE can transmit SRS on one of the comb teeth. SRS can be used by the base station for channel quality estimation to enable frequency-dependent scheduling of the UL.

[0087] Figure 4D Examples of various UL channels within a subframe of a frame are illustrated. The PUCCH can 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 HARQ ACK / NACK feedback. The PUSCH carries data and may additionally be used to carry buffer status reports (BSR), power clearance reports (PHR), and / or UCI.

[0088] Various aspects related to generating power clearance reports for transmissions using full-duplex operation

[0089] Figures 5 to 7 This paper describes various aspects of PHR transmission, configuration, and reporting. A brief background on PHR under current technical standards (e.g., 3GPP TS 38.321) that do not address full-duplex operation is provided below. As discussed above, the UE, for example, uses MAC-CE transmitted on the PUSCH to transmit the PHR to the base station. The PHR is a mechanism used by the UE to report available transmit power to the base station. The PHR is determined for several transmission types. For illustrative purposes, this paper discusses two transmission types, “Type 1” and “Type 3”. The PH for “Type 1” quantifies the difference between the nominal maximum transmit power of the UE and the PUSCH transmit power requirement. The PH for “Type 3” is based on SRS rather than PUSCH. If actual SRS transmission is available but actual PUSCH transmission is unavailable, the PH for “Type 3” is included in the PHR. SRS is the uplink physical signal used by the UE for uplink channel probing (including channel quality estimation and synchronization).

[0090] PHR can be for the actual transmission or a reference format based on higher-layer signaling that is configured with authorization and periodic / semi-persistent PDCCH monitoring timing. Figure 5 An exemplary signaling 500 for a PHR is depicted. For example, signaling 510 depicts an instance of a monitoring event 514 in which the UE receives a DCI that schedules a PUSCH, causing the PHR to be generated and transmitted. The PHR depends on the configuration from the last PHR 512. However, if no monitoring event exists (such as in signaling 520), the PHR depends on a configuration grant (CG-PUSCH) 526, which defines a time period since the last PHR 522 for determining the PHR. Figure 5 The exemplary example of PHR scheduling described herein depends on higher-layer signaling for configuration authorization and periodic / semi-persistent probe reference signal transmission, as well as downlink control information received by the UE in a given period of time, depending on whether the PHR will be reported in a PUSCH scheduled by DCI or in a CG-PUSCH.

[0091] Figure 6 This describes exemplary PHR configuration parameters. The PHR is configured using, for example, PHR-Config 600, as follows: Figure 6 As described in [the document]. A PHR does not trigger a scheduling request. This means that a PHR is only transmitted if the UE has already been allocated PUSCH resources for another reason (e.g., to transmit uplink data). The phr-PeriodicTimer can be used to instruct the UE to transmit periodic PHRs for half-duplex operation instead of full-duplex operation. For example, configuring phr-PeriodicTimer to have an "infinite" value disables periodic reporting. Otherwise, the period is defined in subframes (e.g., in 1 millisecond (ms) units).

[0092] The `phr-Tx-PowerFactorChange` parameter can be used to instruct the UE to transmit a PHR when the path loss has changed beyond the value of this parameter. Configuring an "infinity" value disables path loss-based reporting. Otherwise, a path loss change of 1 dB, 3 dB, or 6 dB can be used to trigger a PHR. A PHR may also be triggered if the UE changes its transmit power back-off requirement (Maximum Power Reduction (MPR)) beyond the value of `phr-Tx-PowerFactorChange`. MPR may increase when the UE uses a higher-order modulation scheme or when using resource blocks close to the edge of the channel bandwidth. MPR may also increase if stricter out-of-band emission or spurious emission requirements are needed.

[0093] The phr-ProhibitTimer is used to prevent the UE from transmitting PHRs too frequently. A prohibition timer is started after a report is transmitted, and subsequent reports triggered by changes in path loss or power backoff will not be transmitted until the timer expires.

[0094] The multiplePHR information element indicates whether the UE uses a "single entry" or "multiple entry" MAC-CE. Figure 7 Illustrative examples of single-entry PHR MAC-CE 710 and multi-entry PHR MAC-CE 720 are depicted. In the single-entry PHR MAC-CE 710, the PHR value occupies a set of 6 bits providing a range from 0 to 63. These 64 signaling values ​​are mapped to PHR results defined in a lookup table.

[0095] "Type 1" PHR is based on the nominal UE maximum transmit power ( The PH is quantified by the difference between the PHR and the uplink transmit power requirement (e.g., the actual or reference transmit power configured for PUSCH or SRS transmission). As illustrated in the exemplary single-entry PHR MAC-CE 710, two additional bits (P and R) are provided for indication. The P field indicates... The value includes whether power backoff due to permitted MPR is included. If the UE has already applied power backoff, the P field is set to "1". The R field is reserved and is filled with "0" by default.

[0096] The single-entry PHR MAC-CE 710 report also includes information for calculating power headroom. This allows the base station to calculate path loss; that is, the base station knows all other variables in the power control equation. The value occupies a set of 6 bits within the report, providing a range from 0 to 63. These 64 signaling values ​​are mapped to values ​​defined in a lookup table.

[0097] The multi-entry PHR MAC-CE 720 begins with a set of seven flags (C1 to C7). These flags indicate which serving cells have PHRs included in the MAC-CE. The V field indicates whether the PHR result is based on a real transmission or a reference format (also known as a virtual transmission). This field also indicates... Whether the value immediately follows the PHR result; for example, whether it is included only if the PHR is based on an actual send. Values.

[0098] like Figure 7 As described in the document, according to current technical standards, the first PHR result within the multi-entry PHR MAC-CE 720 is a "Type 2" PHR and the corresponding "Type 2" PHR value. The second PHR result within the multi-entry PHR MAC-CE 720 is a "Type 1" PHR and the corresponding "Type 1" PHR value. The subsequent PHR results within the multi-entry PHR MAC-CE 720 are the "Type X" PHR and the PHR value corresponding to "Type X". Therefore, "Type X" can be either "Type 1" or "Type 3".

[0099] In full-duplex networks, both half-duplex and full-duplex operations are permitted. However, the power hazard (PH) is calculated based on half-duplex operations, and the power hazard response (PHR) is transmitted based on half-duplex operations. This results in insufficient PHR information for full-duplex operations being calculated and transmitted to the network (e.g., a base station). The aspects described herein provide procedures for determining the type of duplex operation being transmitted (e.g., half-duplex or full-duplex) and calculating the corresponding PH to be transmitted to the network in the PHR. Identifying, calculating, and transmitting the PHR corresponding to the duplex operation being transmitted is a crucial technical feature of power management because different uplink power control considerations exist for half-duplex and full-duplex operations.

[0100] For example, for transmissions using full-duplex operation, uplink power control includes additional considerations such as network-side cross-link interference (CLI) and self-interference (SI). Therefore, uplink power control for half-duplex and full-duplex operations can be different. In some transmission instances, uplink transmission power in full-duplex operation can be increased to address network-side SI. In other transmission instances, uplink transmission power in full-duplex operation can be decreased to reduce CLI. Therefore, full-duplex operation has different considerations and thus a different PHR compared to half-duplex operation.

[0101] The UE transmits a PHR in response to a PHR trigger, the PHR may include information from a reference. Figure 6 The PHR described and illustrated is one of the aforementioned PHRs in the PHR-Config 600 configuration. In some aspects, the PHR-Config may include specific triggers for half-duplex and full-duplex operations, such as phr-PeriodicTimer_HD and phr-PeriodicTimer_FD. phr-PeriodicTimer_FD may be configured to trigger the transmission of a Power Clearance Report (PHR) (FD-PHR) for full-duplex operation when the timer expires. The PHR may be triggered for an actual PUSCH transmission using full-duplex operation or a reference to a full-duplex transmission. Similarly, when phr-PeriodicTimer_HD is enabled and subsequently expires, a PHR may be triggered for an actual PUSCH transmission using half-duplex operation or a reference to a half-duplex operation. In some aspects, a phr-PeriodicTimer may be enabled, and when it expires, two PHRs may be generated, one for each duplex type.

[0102] Other duplex-specific triggers can also be configured in the UE. For example, in addition to the half-duplex disable timer phr-ProhibitTimer_HD and the half-duplex power factor parameter phr-Tx-PowerFactorChange_HD, a disable timer phr-ProhibitTimer_FD corresponding to full-duplex operation and / or a power factor parameter phr-Tx-PowerFactorChange_FD corresponding to full-duplex operation can be implemented to trigger a duplex-specific PHR.

[0103] Regardless of whether the UE uses a duplex-specific trigger or a general trigger to generate a Power Clearance Report (PHR) (duplex-specific or general triggers enable PHR transmission for half-duplex and / or full-duplex operations), the UE needs to determine the duplex type and / or transmission type to correctly calculate the PH value used for reporting. Therefore, in all aspects of generating a power clearance report for transmissions using full-duplex or half-duplex operations, the UE can first determine whether the PHR was triggered for full-duplex or half-duplex operations. This determination can be based on the triggering event. For example, if the PHR trigger is a duplex-specific trigger, such as phr-PeriodicTimer_HD, phr-PeriodicTimer_FD, phr-ProhibitTimer_FD, phr-Tx-PowerFactorChange_FD, phr-ProhibitTimer_HD, or phr-Tx-PowerFactorChange_HD.

[0104] The UE also determines whether the PH calculation corresponds to an actual transmission or a reference transmission. An actual transmission refers to an instance where there is a PUSCH transmission opportunity (e.g., i>0) or an SRS transmission opportunity (e.g., i>0). A reference transmission refers to an instance where there is no actual PUSCH transmission (e.g., i=0) or SRS transmission opportunity (e.g., i=0). Therefore, the UE also determines whether the transmission type is "Type 1" or "Type 3". "Type 3" or SRS transmission occurs when no PUSCH transmission is available. SRS is the uplink physical signal used by the UE for uplink channel probing (including channel quality estimation and synchronization).

[0105] Various aspects related to generating power clearance reports for actual transmissions using full-duplex operation

[0106] When the UE determines that the "Type 1" power clearance report for full-duplex operation for the active serving cell is based on actual PUSCH transmission, then for the PUSCH transmission timing i on the active uplink bandwidth portion (UL BWP) b of carrier f of serving cell c, the UE calculates the "Type 1" power clearance report for full-duplex operation according to Equation 1:

[0107] .

[0108] In equation 1, This refers to the maximum UE transmit power for full-duplex operation. This is the maximum power the UE can transmit. As noted above, the maximum UE transmit power ( This may include power back-off due to permitted MPR.

[0109] In equation 1, This is the nominal transmit power value parameter for full-duplex operation. The nominal transmit power value parameter consists of the sum of the following two: cell-specific nominal components. It is provided by a higher layer, where j=0 and 1; and UE-specific components. This is provided by a higher layer, where j=0 and 1. The nominal transmit power value can be defined in the RRC, which specifies the power the UE should transmit for a particular carrier interval of resource blocks. The nominal transmit power value is part of open-loop power control.

[0110] In equation 1, Also known as the allocated resource block parameter or allocation value, it is the bandwidth assigned to the PUSCH resource, which is expressed in terms of the number of resource blocks and applies to subframe i. Value and Multiply (where μ is the subcarrier spacing index) to scale the transmit power proportionally to the bandwidth allocated to the resource; for example, resource blocks with larger subcarrier spacing occupy a wider bandwidth and are therefore allocated higher transmit power.

[0111] In equation 1, This is the fractional power control multiplier for full-duplex operation. This affects the open-loop power control parameters because it is multiplied by the path loss (PL). Fractional power control reduces the gradient of the UE's transmit power characteristics, which continuously leads to a decrease in receive power density.

[0112] In equation 1, The value in dB is a downlink path loss estimate for full-duplex operation. This downlink path loss estimate is based on the reference signal (RS) index q of the active downlink DL BWP of the serving cell c in the UE. d Calculated.

[0113] In equation 1, This is the modulation and decoding scheme (MCS) offset, which is used to control UE power based on the MCS allocated for full-duplex operation. The requirements for this mechanism depend on the specific implementation of link adaptation at the network (e.g., the base station).

[0114] In equation 1, This is the closed-loop power control component. The closed-loop power control calculation is performed for the active UL BWPb of carrier f of serving cell c in PUSCH transmission timing i, and where l represents the power control adjustment state.

[0115] As shown in Equation 1, the uplink transmit power requirement (which can be the transmit power of the actual PUSCH transmit for full-duplex operation) is based on the full-duplex parameters of the actual PUSCH transmit. The full-duplex parameters of the actual PUSCH transmit include the nominal transmit power value (e.g., ...). ), Assigned values ​​(e.g., ), fractional power control multiplier (e.g., ), actual path loss measurement (e.g., ), modulation and decoding scheme offset (e.g., ) and closed-loop power control components (e.g., ).

[0116] When the UE determines that the "Type 3" power clearance report for full-duplex operation for the active serving cell is based on the actual SRS transmission, then for the SRS transmission timing i on the active UL BWP b of carrier f of serving cell c, the UE calculates the "Type 3" power clearance report for full-duplex operation according to Equation 2:

[0117] .

[0118] It should be noted that Equation 2 shares similar parameters with Equation 1; however, the parameters of Equation 2 correspond to SRS transmission for full-duplex operation, not PUSCH transmission for full-duplex operation. The SRS PH equation (Equation 2) does not include MCS-related terms because SRS does not transmit any information bits. Therefore, only the differences between the equations will be discussed.

[0119] For example, nominal UE transmit power Configure using p0 within the SRS-ResourceSet parameter structure, where each instance of the SRS-ResourceSet can be configured with different nominal UE transmit powers. Variables Referencing a specific instance of SRS-ResourceSet. Additionally, Indicates that the UE uses an index The path loss is measured by the downlink reference signal.

[0120] As shown in Equation 2, the uplink transmit power requirement (which can be the transmit power of the actual SRS transmit for full-duplex operation) is based on the full-duplex parameters of the actual SRS transmit. The full-duplex parameters of the actual SRS transmit include the nominal transmit power value (e.g., ...). ), Assigned values ​​(e.g., ), fractional power control multiplier (e.g., ), actual path loss measurement (e.g., ) and closed-loop power control components (e.g., In some respects, the closed-loop power control component transmitted for SRS (e.g., Equation 2) is set to be equal to the closed-loop power control component transmitted for PUSCH (e.g., Equation 1).

[0121] Various aspects related to generating power clearance reports for reference transmission using full-duplex operation

[0122] When the UE determines that the "Type 1" power clearance report for full-duplex operation for the active serving cell is based on reference PUSCH transmission, for example, when the UE determines that there is no actual PUSCH transmission using full-duplex operation, the UE calculates the "Type 1" power clearance report for full-duplex operation according to Equation 3:

[0123] .

[0124] In equation 3, This refers to the maximum UE transmit power for full-duplex operation. This is the maximum power the UE can transmit. As noted above, the maximum UE transmit power ( This may include power back-off due to permitted MPR.

[0125] In equation 3, It can be calculated based on MPR=xdB, A-MPR=ydB, and P-MPR=zdB, where x, y, and z are fixed in the specification or configured by RRC. Note that if (x,y,z)=(0,0,0), then... This corresponds to half-duplex operation. Additionally, if the configuration for x, y, and z is missing, the UE may assume these values ​​are zero. In some aspects, the maximum transmit power is based on at least one of a Maximum Power Reduction (MPR) value, an Additional Maximum Power Reduction (A-MPR) value, or a Power Management Maximum Power Reduction (P-MPR) value. The MPR value, A-MPR value, or P-MPR value may be stored in one or more memories of the UE. The MPR value, A-MPR value, or P-MPR value is based on specifications, such as 3GPP standards and / or other technical standards that define one or more MPR values. In some aspects, the UE may receive the MPR value, A-MPR value, or P-MPR value via an RRC signal. The received value may be stored in one or more memories of the UE.

[0126] In equation 3, This is the nominal transmit power value parameter for full-duplex operation. The nominal transmit power value parameter consists of the sum of the following two: cell-specific nominal components. It is provided by a higher layer, where j=0 and 1; and UE-specific components. This is provided by a higher layer, where j=0 and 1. The nominal transmit power value can be defined in the RRC, which specifies the power the UE should transmit for a particular carrier interval of resource blocks. The nominal transmit power value is part of open-loop power control.

[0127] In equation 3, This is the fractional power control multiplier for full-duplex operation. This affects the open-loop power control parameters because it is multiplied by the path loss (PL). Fractional power control reduces the gradient of the UE's transmit power characteristics, which continuously leads to a decrease in receive power density.

[0128] In equation 3, The value in dB is a downlink path loss estimate for full-duplex operation. This downlink path loss estimate is based on the reference signal (RS) index q of the active downlink DL BWP of the serving cell c in the UE. d Calculated.

[0129] In equation 3, This is the closed-loop power control component. The closed-loop power control calculation is performed for the active UL BWPb of carrier f of serving cell c in PUSCH transmission timing i, and where l represents the power control adjustment state.

[0130] As shown in Equation 3, the uplink transmit power requirement (which may be the reference power transmitted via the reference PUSCH for full-duplex operation) is based on the full-duplex parameters transmitted via the reference PUSCH. The full-duplex parameters transmitted via the reference PUSCH include the nominal transmit power value (e.g., ...). ), fractional power control multiplier (e.g., ), reference path loss measurement (e.g., ) and closed-loop power control components (e.g., ).

[0131] When the UE determines that the "Type 3" power clearance report for full-duplex operation for the active serving cell is based on a reference SRS transmission, for example, when the UE determines that there is no actual SRS transmission using full-duplex operation, the UE calculates the "Type 1" power clearance report for full-duplex operation according to Equation 4:

[0132] .

[0133] In equation 4, This refers to the maximum UE transmit power for full-duplex operation. This is the maximum power the UE can transmit. As noted above, the maximum UE transmit power ( This may include power back-off due to permitted MPR.

[0134] In equation 4, It can be calculated based on MPR=xdB, A-MPR=ydB, and P-MPR=zdB, where x, y, and z are fixed in the specification or configured by RRC. Note that if (x,y,z)=(0,0,0), then... This corresponds to half-duplex operation. Additionally, if the configuration for x, y, and z is missing, the UE may assume these values ​​are zero. In some aspects, the maximum transmit power is based on at least one of a Maximum Power Reduction (MPR) value, an Additional Maximum Power Reduction (A-MPR) value, or a Power Management Maximum Power Reduction (P-MPR) value. The MPR value, A-MPR value, or P-MPR value may be stored in one or more memories of the UE. The MPR value, A-MPR value, or P-MPR value is based on specifications, such as 3GPP standards and / or other technical standards that define one or more MPR values. In some aspects, the UE may receive the MPR value, A-MPR value, or P-MPR value via an RRC signal. The received value may be stored in one or more memories of the UE.

[0135] In equation 4, The p0 parameter within the SRS-ResourceSet parameter structure can be used for configuration, where each instance of the SRS-ResourceSet can be configured using different nominal UE transmit powers. Variables Referencing a specific instance of SRS-ResourceSet. Additionally, Indicates that the UE uses an index The path loss measured by the downlink reference signal. For example, It is the SRS resource set corresponding to SRS-ResourceSetId=a, where a=2.

[0136] In equation 4, This is the fractional power control multiplier for full-duplex operation. This affects the open-loop power control parameters because it is multiplied by the path loss (PL). Fractional power control reduces the gradient of the UE's transmit power characteristics, which continuously leads to a decrease in receive power density.

[0137] In equation 4, The value in dB is a downlink path loss estimate for full-duplex operation. This downlink path loss estimate is based on the reference signal (RS) index q of the active downlink DL BWP of the serving cell c in the UE.d Calculated.

[0138] In equation 4, This is the closed-loop power control component. The closed-loop power control calculation is performed for the active UL BWPb of carrier f of serving cell c in SRS transmission timing i, where l represents the power control adjustment state.

[0139] As shown in Equation 4, the uplink transmit power requirement (which may be the reference power for full-duplex operation using the reference SRS transmit) is based on the full-duplex parameters of the reference SRS transmit. The full-duplex parameters of the reference SRS transmit include the nominal transmit power value (e.g., ...). ), fractional power control multiplier (e.g., ), reference path loss measurement (e.g., ) and closed-loop power control components (e.g., ).

[0140] The PHR, then generated by the UE based on one of equations 1 to 4 or a similar calculation, is transmitted to the network. The PHR includes the power clearance value for full-duplex operation (FD-PHR). In some respects, the PHR also includes the maximum transmit power for FD operation.

[0141] The UE can be configured to transmit FD-PHR using a single-entry PHR MAC-CE. The single-entry PHR MAC-CE may include an indication that the PHR corresponds to full-duplex operation. For example, a reserved field R, such as... Figure 7 This is as described in the single-entry PHR MAC-CE 710 report. For example, when the R value of the reserved field is set to "1", the indication of "1" tells the network that the PH value in the PHR corresponds to full-duplex operation, while "0" indicates that the PH value in the PHR corresponds to half-duplex operation, and vice versa.

[0142] The UE can be configured to use a sequence of single-entry PHR MAC-CE (e.g., reference). Figure 7 The depicted single-entry PHRMAC-CE 710 is used to transmit PHRs (HD-PHR) and FD-PHRs for half-duplex operation. For example, a first single-entry PHR MAC-CE including an indication that HD-PHR corresponds to half-duplex operation and a subsequent single-entry PHR MAC-CE including an indication that FD-PHR corresponds to full-duplex operation can be used to transmit HD-PHR and FD-PHR. The PHR reported in the first single-entry PHR MAC-CE may correspond to FD-PHR, and the PHR reported in the subsequent single-entry PHR MAC-CE may correspond to HD-PHR.

[0143] A single-entry PHR MAC-CE can include an indication that the PHR corresponds to a full-duplex operation. For example, a reserved field R, such as... Figure 7 This is as described in the single-entry PHR MAC-CE 710 report. For example, when the R value of the reserved field is set to "1", it indicates to the network that the PH value in the PHR corresponds to full-duplex operation, while "0" indicates that the PH value in the PHR corresponds to half-duplex operation, and vice versa.

[0144] The UE can be configured to use, for example Figure 7 The multi-entry PHR MAC-CE 720 depicted herein is used to transmit HD-PHR and FD-PHR. Therefore, the multi-entry PHR MAC-CE 720 is configured to report PHR results for different operating modes (such as half-duplex and / or full-duplex), rather than reporting PHR results for multiple serving cells. In some aspects, the first PHR result within the multi-entry PHR MAC-CE 720 is FD-PHR. In some aspects, the first PHR result reported within the multi-entry PHR MAC-CE 720 is FD-PHR, and subsequent PHR results reported within the multi-entry PHR MAC-CE 720 are HD-PHR. In other aspects, the first PHR result reported within the multi-entry PHR MAC-CE 720 is HD-PHR, and subsequent PHR results reported within the multi-entry PHR MAC-CE 720 are FD-PHR.

[0145] In the multi-entry PHR MAC-CE 720, the order in which PHRs are reported can be pre-configured or RRC-configured.

References to singular elements are not intended to mean “only one” (unless specifically stated as “only one”), but rather “one or more”. Unless otherwise specified, definite articles (e.g., “the” or “described”) subsequently used with an element (e.g., “processor”) are not intended to give that element a singular meaning (e.g., “only one”). For example, unless otherwise specified, references to elements (e.g., “processor”, “controller”, “memory”, “transceiver”, “antenna”, “the processor”, “the controller”, “the memory”, “the transceiver”, “the antenna”, etc.) should be understood to refer to one or more elements (e.g., “one or more processors”, “one or more controllers”, “one or more memories”, “a plurality of transceivers”, etc.). The terms “set” and “group” are intended to include one or more elements and may be used interchangeably with “one or more”. In the case of references to one or more elements performing a function (e.g., steps of a method), one element may perform all the functions, or more than one element may collectively perform those functions. When more than one element performs these functions together, each function does not need to be performed by every single element (e.g., different functions can be performed by different elements), and / or each function does not need to be performed by only one element as a whole (e.g., different elements can perform different sub-functions of a function). Similarly, when referring to one or more elements configured to cause another element (e.g., a device) to perform a function, one element may be configured to cause another element to perform all functions, or more than one element may be jointly configured to cause another element to perform these functions. Unless otherwise specifically stated, the term "some" means one or more. All structural and functional equivalents of the elements of the various aspects described throughout this disclosure that are currently or hereafter known to those skilled in the art are intended to be covered by the claims. Furthermore, nothing disclosed herein is intended to be offered to the public, whether or not such disclosure is explicitly recited in the claims.
