Power allocation prioritization at full duplex user equipment

Abstract

Aspects presented herein can enable FD devices to apply FD transmission-specific power backoff and / or power allocation prioritization rules. In one aspect, a UE determines FD-specific power backoffs, the FD-specific power backoffs being associated with each of at least one of a plurality of transmissions in a slot, the slot being configured as an FD slot, each FD-specific power backoff being based on whether the corresponding transmission would cause self-interference with a DL reception in the FD slot, the plurality of transmissions overlapping in time. The UE determines a transmission power for each of the at least one of the transmissions in the FD slot based on the determined FD-specific power backoff for each of the at least one of the transmissions. The UE transmits one or more of the at least one of the transmissions based on the determined transmission power for the corresponding transmission.

Description

[0001] Cross-reference to related applications

[0002] This application claims the benefit of U.S. non-provisional patent application serial number 17 / 392,886, filed August 3, 2021, entitled “POWER ALLOCATION PRIORITIZATIONAT FULL DUPLEX USER EQUIPMENTS”, which is expressly incorporated herein by reference in its entirety. Technical Field

[0003] This disclosure relates generally to communication systems, and more specifically to wireless communication with regard to power distribution. Background Technology

[0004] 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 employ multiple access technologies that enable 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.

[0005] 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, country, region, and even global levels. An example of a telecommunications standard is 5G New Radio (NR). 5G NR is part of the Continuous Mobile Broadband Evolution (CLE) 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 may 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 them. Summary of the Invention

[0006] The following is a simplified overview of one or more aspects to provide a basic understanding of them. This overview is not a comprehensive summary of all anticipated aspects, nor is it intended to identify key or important elements of all aspects, nor to describe the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed descriptions that follow.

[0007] In one aspect of this disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus determines full-duplex (FD) specific power backoff associated with each of at least one of a plurality of transmissions in a time slot configured as an FD time slot, each FD specific power backoff based on whether the corresponding transmission would cause self-interference to downlink (DL) reception in that FD time slot, the plurality of transmissions overlapping in time. Based on the determined FD specific power backoff of each of the at least one transmissions, the apparatus determines the transmission power of each of the at least one transmissions in the FD time slot. Based on the determined transmission power of the corresponding transmission, the apparatus transmits one or more of the at least one transmissions.

[0008] To achieve the foregoing and related objectives, one or more aspects include the features fully described below and specifically pointed out in the claims. The following description and drawings illustrate some exemplary features of one or more aspects in detail. However, these features indicate only some of the various ways in which the principles of these aspects may be employed, and this specification is intended to include all such aspects and their equivalents.

[0038] The detailed description below, taken in conjunction with the accompanying drawings, is intended as a description of various configurations and not as representing the only configuration in which the concepts described herein can be practiced. To provide a thorough understanding of the various concepts, the detailed description includes specific details. However, it will be apparent to those skilled in the art that these concepts can be practiced without these specific details. In some cases, well-known structures and components are shown in block diagram form to avoid obscuring these concepts.

[0039] Several aspects of a telecommunications system will now be described with reference to various apparatuses and methods. These apparatuses and methods will be described in detail below and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively, “elements”). Such elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.

[0040] For example, elements, any part of elements, or any combination of elements can be implemented as a "processing system" that includes one or more processors. 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, gate logic, discrete hardware circuits, and other suitable hardware configured to perform the various functions described throughout this disclosure. One or more processors in a processing system can execute software. Whether referred to as software, firmware, middleware, microcode, hardware description language, or other names, software should be broadly interpreted as meaning 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, etc.

[0041] Accordingly, in one or more exemplary embodiments, the described functionality can be implemented using hardware, software, or any combination thereof. If implemented in software, the functionality can 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 can be any available medium accessible to a computer. By way of example and not limitation, 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 capable of being used to store computer-executable code in the form of instructions or data structures accessible to a computer.

[0042] While aspects and implementations are described herein by way of example, those skilled in the art will understand that additional implementations and use cases may arise in many other arrangements and scenarios. The innovations described herein can be implemented across many different platform types, devices, systems, shapes, sizes, and package arrangements. For example, implementations and / or uses 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, artificial intelligence (AI) enabled devices, etc.). While some examples may or may not specifically point to a use case or application, the applicability of various types of the described innovations can emerge. Implementations 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 aspects of the described innovations. 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 / accumulators, etc.). The innovations described herein are intended to be implemented in a variety of devices, chip-level components, systems, distributed arrangements, aggregated or deaggregated components, end-user equipment, etc., of different sizes, shapes, and constructions.

[0043] Figure 1Figure 100 illustrates an example of a wireless communication system and access network. The wireless communication system (also referred to as a Wireless Wide Area Network (WWAN)) includes a base station 102, a UE 104, an evolved packet core (EPC) 160, and another core network 190 (e.g., a 5G core (5GC)). Base station 102 may include macro cells (high-power cellular base stations) and / or small cells (low-power cellular base stations). Macro cells include base stations. Small cells include femtocells, picocells, and microcells.

[0044] The aspects presented herein can improve wireless communication for FD devices or FD-capable devices (e.g., UEs operating in FD mode) by enabling full-duplex devices to apply power backoff to FD operations. The aspects presented herein can enable FD devices to determine whether to apply an FD-specific MPR (e.g., when uplink and downlink transmissions at least partially overlap in time) and / or whether to apply power allocation priority ordering rules to UL / SL transmissions associated with FD transmissions, etc.

[0045] In some aspects, UE 104 may include a power backoff and priority ordering component 198 configured to apply power backoff and / or power allocation priority ordering to at least one of the multiple transmissions when at least one DL reception at least partially overlaps in time with multiple transmissions. In one configuration, the power backoff and priority ordering component 198 may determine an FD-specific power backoff associated with each of at least one of the multiple transmissions in a time slot configured as an FD time slot, each FD-specific power backoff based on whether the corresponding transmission would cause self-interference with DL reception in that FD time slot, the multiple transmissions overlapping in time. In such a configuration, the power backoff and priority ordering component 198 may determine the transmission power of each of the at least one transmissions in the FD time slot based on the determined FD-specific power backoff for each of the at least one transmissions. In such a configuration, the power backoff and priority ordering component 198 may transmit one or more of the at least one transmissions based on the determined transmission power of the corresponding transmission.

[0046] Base station 102 configured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) can be interface-connected to EPC 160 via a first backhaul link 132 (e.g., S1 interface). Base station 102 configured for 5G NR (collectively referred to as Next Generation RAN (NG-RAN)) can be interface-connected to core network 190 via a second backhaul link 184. Among other functions, base station 102 can perform one or more of the following functions: transmission of user data, radio channel encryption and decryption, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection establishment and release, load balancing, distribution of non-access stratum (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS), subscriber and device tracking, RAN information management (RIM), paging, location, and transmission of alarm messages. Base stations 102 can communicate directly or indirectly with each other via a third backhaul link 134 (e.g., an X2 interface) (e.g., via EPC 160 or core network 190). The first backhaul link 132, the second backhaul link 184, and the third backhaul link 134 can be wired or wireless.

[0047] Base station 102 can wirelessly communicate with UE 104. Each base station in base station 102 can provide communication coverage for a corresponding geographic coverage area 110. Overlapping geographic coverage areas 110 may exist. For example, small cell 102' may have a coverage area 110' that overlaps with the coverage areas 110 of one or more macro base stations 102. A network that includes both small cells and macro cells may be referred to as a heterogeneous network. A heterogeneous network may also include a Home Evolution Node B (eNB) (HeNB), which can provide service to a restricted group referred to as a Closed Subscriber Group (CSG). The communication link 120 between base station 102 and UE 104 may include uplink (UL) (also referred to as reverse link) transmission from UE 104 to base station 102 and / or downlink (DL) (also referred to as forward link) transmission from base station 102 to UE 104. The communication link 120 may use multiple-input multiple-output (MIMO) antenna technologies, including spatial multiplexing, beamforming, and / or transmit diversity. The communication link may be transmitted through one or more operators. For each carrier allocated in a carrier aggregation totaling 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 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 may be referred to as the primary cell (PCell) and the secondary component carrier may be referred to as the secondary cell (SCell).

[0048] Some UEs 104 may communicate with each other using a device-to-device (D2D) communication link 158. The D2D communication link 158 may use DL / UL WWAN spectrum. The D2D communication link 158 may use one or more sideline channels, such as the Physical Sideline Broadcast Channel (PSBCH), Physical Sideline Discovery Channel (PSDCH), Physical Sideline Shared Channel (PSSCH), and Physical Sideline Control Channel (PSCCH). D2D communication can be achieved through a variety of wireless D2D communication systems, such as, for example, WiMedia, Bluetooth, Wi-Fi based on the IEEE 802.11 standard, LTE, or NR.

[0049] The wireless communication system may also include a Wi-Fi access point (AP) 150 that communicates with a Wi-Fi station (STA) 152 via a communication link 154, for example, in unlicensed spectrum at 5 GHz. When communicating in unlicensed spectrum, the STA 152 / AP 150 may perform a free channel assessment (CCA) before communication to determine whether the channel is available.

[0050] Small cell 102' can operate in licensed and / or unlicensed spectrum. When operating in unlicensed spectrum, small cell 102' can employ NR and use the same unlicensed spectrum (e.g., 5 GHz, etc.) as used by Wi-Fi AP 150. Small cell 102' employing NR in unlicensed spectrum can improve the coverage and / or increase the capacity of the access network.

[0051] The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc., based on frequency / wavelength. In 5G NR, the two initial operating bands have been designated as frequency range names FR1 (410MHz-7.125GHz) and FR2 (24.25GHz-52.6GHz). Although a portion of FR1 is greater than 6GHz, in various documents and articles, FR1 is often referred to as the "below 6GHz" band (interchangeably). Similar naming issues sometimes occur with FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although this is distinct from the Extremely High Frequency (EHF) band (30GHz-300GHz) designated as "millimeter wave" by the International Telecommunication Union (ITU).

[0052] The frequencies between FR1 and FR2 are generally referred to as intermediate frequency (IF) bands. Recent 5G NR studies have designated the operating bands used for these IF bands as the frequency range name FR3 (7.125GHz-24.25GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, thus effectively extending the features of FR1 and / or FR2 to IF band frequencies. Furthermore, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6GHz. For example, three higher operating bands have been designated as the frequency range names FR4a or FR4-1 (52.6GHz-71GHz), FR4 (52.6GHz-114.25GHz), and FR5 (114.25GHz-300GHz). Each of these higher frequency bands falls within the EHF band.

[0053] In light of the foregoing, unless otherwise specified, it should be understood that, as used herein, the term "below 6 GHz" and the like can broadly refer to frequencies less than 6 GHz, within FR1, or including intermediate frequency band frequencies. Furthermore, unless otherwise specified, it should be understood that, as used herein, the term "millimeter wave" and the like can broadly refer to frequencies that can include intermediate frequency band frequencies, within FR2, FR4, FR4-a or FR4-1 and / or FR5, or within the EHF band.

[0054] Base station 102 (whether a small cell 102' or a large cell (e.g., a macro base station)) may include and / or be referred to as an eNB, a next-generation node B (gNodeB, gNB), or another type of base station. Some base stations (such as gNB 180) may operate in conventional sub-6 GHz spectrum, in millimeter wave frequencies, and / or near-millimeter wave frequencies to communicate with UE 104. When gNB 180 operates in millimeter wave or near-millimeter wave frequencies, gNB 180 may be referred to as a millimeter wave base station. Millimeter wave base station 180 may utilize beamforming 182 with UE 104 to compensate for path loss and short ranging. Base station 180 and UE 104 may each include multiple antennas (such as antenna elements, antenna panels, and / or antenna arrays) to facilitate beamforming.

[0055] Base station 180 can transmit beamformed signals to UE 104 in one or more transmit directions 182'. UE 104 can receive beamformed signals from base station 180 in one or more receive directions 182'. UE 104 can also transmit beamformed signals to base station 180 in one or more transmit directions. Base station 180 can receive beamformed signals from UE 104 in one or more receive directions. Base station 180 / UE 104 can perform beamforming to determine the optimal receive and transmit directions for each of base station 180 / UE 104. The transmit and receive directions of base station 180 can be the same or different. The transmit and receive directions of UE 104 can be the same or different.

[0056] EPC 160 may include 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 Packet Data Network (PDN) Gateway 172. MME 162 can communicate with Home Subscriber Server (HSS) 174. MME 162 is the control node that handles signaling between UE 104 and EPC 160. Typically, MME 162 provides bearer and connection management. All 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 Service 176. IP Service 176 may include the Internet, intranet, IP Multimedia Subsystem (IMS), PS streaming service, and / or other IP services. The BM-SC 170 can provide functions for MBMS user service provisioning and delivery. The BM-SC 170 can act as an entry point for content provider MBMS transmission, authorize and initiate MBMS bearer services in the Public Land Mobile Network (PLMN), and schedule MBMS transmissions. The MBMS gateway 168 can be used to allocate MBMS services to base station 102 belonging to a Multicast-Broadcast Single Frequency Network (MBSFN) area belonging to a broadcast-specific service, and can be responsible for session management (start / stop) and collecting eMBMS-related billing information.

[0057] The core network 190 may include Access and Mobility Management Functions (AMF) 192, other AMFs 193, Session Management Functions (SMF) 194, and User Plane Functions (UPF) 195. AMF 192 can communicate with Unified Data Management (UDM) 196. AMF 192 is the control node for processing signaling between UE 104 and the core network 190. Generally, AMF 192 provides QoS flow and session management. All user Internet Protocol (IP) packets are transmitted through UPF 195. UPF 195 provides UE IP address allocation and other functions. UPF 195 is connected to IP service 197. IP service 197 may include the Internet, intranet, IP Multimedia Subsystem (IMS), Packet Switched (PS) Streaming (PSS) service, and / or other IP services.

[0058] Base stations may include and / or be referred to as gNB, Node B, eNB, access point, base transceiver, radio base station, radio transceiver, transceiver function, Basic Service Set (BSS), Extended Service Set (ESS), Transmitter Receiver Point (TRP), or some other suitable terminology. Base station 102 provides access to EPC 160 or core network 190 for UE 104. Examples of UE 104 include cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radio units, global positioning systems, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablet devices, 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 devices. 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, radio unit, remote unit, mobile device, radio device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, radio terminal, remote terminal, handheld device, user agent, mobile client, client, or any other suitable term. In some scenarios, the term UE may also be applied to one or more accompanying devices, such as in a device constellation arrangement. One or more of these devices may jointly access the network and / or individually access the network.

[0059] 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 Multiplexing (FDD) (where subframes within a specific set of subcarriers (carrier system bandwidth) are dedicated to either DL or UL) or Time Division Multiplexing (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 with 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 DL and UL, respectively. Other slot formats 2-61 include a mixture of DL symbols, UL symbols, and flexible symbols. The UE is configured with a slot format by receiving a Slot Format Indicator (SFI) (dynamically configured via DL Control Information (DCI) or semi-statically / statically controlled via Radio Resource Control (RRC) signaling). Note that the following description also applies to the 5G NR frame structure as TDD.

[0060] 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 subframes (1 ms) of the same size. 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 can be CP Orthogonal Frequency Division Multiplexing (OFDM) (CP-OFDM) symbols. Symbols on the UL can be CP-OFDM symbols (for high-throughput scenarios) or Discrete Fourier Transform (DFT) Extended OFDM (DFT-s-OFDM) symbols (also known as Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols) (for power-constrained scenarios; limited to single-stream transmission). The number of time slots within a subframe is based on the CP and parameter set. The parameter set defines the subcarrier spacing (SCS) and effectively defines the symbol length / duration, which is equal to 1 / SCS.

[0061]

[0062] For a normal CP (14 symbols / slot), different parameter sets μ0 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. Correspondingly, for the normal CP and parameter set μ, there are 14 symbols / slot and 2... μ One time slot / subframe. The subcarrier spacing can be equal to 2. μ*15kHz, where μ is the parameter set from 0 to 4. Therefore, the subcarrier spacing is 15kHz for parameter set μ = 0 and 240kHz for parameter set μ = 4. The symbol length / duration is inversely correlated with the subcarrier spacing. Figures 2A to 2D Examples are provided for a normal CP with 14 symbols per time slot and a parameter set μ=2 with 4 time slots per subframe. 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 different bandwidth portions (BWPs) of frequency division multiplexing (see [link to example]). Figure 2B Each BWP can have a specific set of parameters and CP (normal or extended).

[0063] 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.

[0064] like Figure 2A As shown, 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).

[0065] 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 within an OFDM symbol of an 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 a PDCCH search space (e.g., a common search space, a UE-specific search space) during PDCCH monitoring on the CORESET, where the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs can 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 the 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.

[0066] like Figure 2C As shown, some REs carry DM-RS (denoted as R for a specific 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 second symbols of the PUSCH. Depending on whether a short or long PUCCH is transmitted and 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 combs. The SRS can be used by the base station for channel quality estimation to enable frequency-dependent scheduling of the UL.

[0067] 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), precoding 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 headroom reports (PHR), and / or UCI.

[0068] Figure 3 This is a block diagram illustrating communication between base station 310 and UE 350 in the access network. In the DL, IP packets from EPC 160 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 upper-layer packet data unit (PDU) transmission, 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 transmit channels, multiplexing of MAC SDUs onto transmit blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction via HARQ, priority handling, and logical channel priority ordering.

[0069] 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 transmit channel, forward error correction (FEC) encoding / decoding of the transmit 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 for the signal constellation diagram based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-ary phase shift keying (M-PSK), M-ary quadrature amplitude modulation (M-QAM)). The encoded 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 subsequently combined using inverse fast Fourier transform (IFFT) to generate a physical channel for carrying the time-domain OFDM symbol stream. The OFDM stream is spatially precoded to generate multiple spatial streams. Channel estimates from channel estimator 374 are used to determine coding and modulation schemes, as well as for spatial processing. Channel estimates can be derived based on reference signals 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 use its respective spatial stream to modulate a radio frequency (RF) carrier for transmission.

[0070] At UE 350, each receiver 354RX receives signals through its respective antenna 352. Each receiver 354RX recovers the information modulated onto the RF carrier and provides this 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, they can be merged into a single OFDM symbol stream by the RX processor 356. 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 includes 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 signal constellation points most likely to be transmitted by base station 310. These soft decisions can be based on the channel estimate calculated by channel estimator 358. Subsequently, the soft decision is 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.

[0071] The controller / processor 359 may be associated with a memory 360 that stores program code and data. The 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 the transmit and logical channels to recover IP packets from the EPC 160. The controller / processor 359 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0072] 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 transmission, 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 transmission channels, multiplexing of MAC SDUs to TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction via HARQ, priority handling, and logical channel priority ordering.

[0073] The TX processor 368 can use the channel estimate derived from the reference signal or feedback transmitted by the channel estimator 358 from the base station 310 to select an appropriate coding 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 modulate an RF carrier with its own spatial stream for transmission.

[0074] 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 respective antenna 320. Each receiver 318RX recovers the information modulated onto the RF carrier and provides that information to RX processor 370.

[0075] The controller / processor 375 may be associated with a memory 376 that stores program code and data. The 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 between the transmit and logical channels to recover IP packets from the UE 350. IP packets from the controller / processor 375 can be provided to the EPC 160. The controller / processor 375 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0076] In one example, at least one of the TX processor 368, RX processor 356, and controller / processor 359 can be configured to combine Figure 1 The power backoff and priority sorting components 198 are used to perform various aspects.

[0077] Communication networks such as 5G NR can support full-duplex (FD) operation, where a wireless device (e.g., a UE) can simultaneously send data to and receive data from another wireless device (e.g., a base station). Therefore, full-duplex operation can increase the capacity of the communication network. In some examples, full-duplex operation may include in-band full-duplex (IBFD) operation and / or sub-band frequency division duplex (FDD) operation (also known as "flexible duplex" operation). Figure 4A Figure 400A illustrates an example of IBFD operation according to various aspects of this disclosure. For IBFD operation, a wireless device may simultaneously transmit data (e.g., uplink data) and receive data (e.g., downlink data) on the same frequency resources (e.g., transmission and reception may at least partially overlap in time and frequency). For example, as shown in Figure 400A, downlink (DL) transmission 402A may completely overlap with uplink (UL) transmission 404A, or DL ​​transmission 402B may partially overlap with UL transmission 404B, and so on.

[0078] Figure 4B Figure 400B illustrates an example of subband FDD operation according to various aspects of this disclosure. For subband FDD operation, a radio device can simultaneously transmit data (e.g., uplink data) and receive data (e.g., downlink data) on different frequency resources (e.g., transmission and reception may at least partially overlap in time, but not in frequency). For example, a UE can simultaneously receive DL transmission 402C and transmit UL transmission 404C using different frequency resources. DL transmission 402C and UL transmission 404C (in frequency) can be separated by a guard band 406. In other words, the guard band 406 provides a frequency gap or frequency spacing between DL resources (e.g., DL transmission 402C) and UP resources (e.g., UL transmission 404C).

[0079] Figure 5 Figure 500 illustrates an example of static time-division duplex (TDD) operation (e.g., non-FD operation) according to various aspects of this disclosure. For static FDD operation, DL transmission and UL transmission can be time-division multiplexed (TDMed) transmissions, such that DL transmission and UL transmission do not overlap in time. In other words, the UE can transmit uplink data to or receive downlink data from the base station / TRP in a single transmission. Furthermore, the UE can use the same frequency bandwidth (e.g., 100 MHz) to transmit uplink data and receive downlink data.

[0080] Figure 6 Figure 600 illustrates an example of subband FD (SBFD) operation according to various aspects of this disclosure. For subband FD operation, DL transmission and UL transmission can occur simultaneously (e.g., within the same time slot). For example, a UE can receive DL transmissions from one set of antenna panels of a base station or TRP, and the UE can simultaneously transmit UL transmissions to another set of antenna panels of the base station or TRP. In some examples, DL transmission and UL transmission can be based on frequency division duplex (FDD), where DL transmission and UL transmission can use different frequency bandwidths. For example, a UE can use a portion of the available bandwidth (e.g., 80 MHz of a 100 MHz available bandwidth) to receive downlink data, and the UE can simultaneously use another portion of the available bandwidth (e.g., the remaining 20 MHz of a 100 MHz available bandwidth) to transmit uplink data. Therefore, full-duplex operation improves the transmission coverage and latency of the radio device because the radio device can transmit and receive data simultaneously.

[0081] Figure 7 Figure 700 illustrates an example of an SBFD timeslot format according to various aspects of this disclosure. For SBFD operation, a timeslot where a frequency band is available for both UL transmission and DL transmission may be referred to as a "D+U timeslot" and / or an "FD timeslot". The D+U timeslot allows DL transmission and UL transmission to occur within overlapping frequency bands (e.g., for in-band full-duplex) or adjacent frequency bands (e.g., for sub-band full-duplex). In a given D+U symbol (e.g., a symbol within a D+U timeslot), a half-duplex UE (e.g., a non-FD UE) may transmit in the UL band or receive in the DL band. Conversely, in a given D+U symbol, an FD UE may transmit in the UL band and / or receive in the DL band within the same timeslot / symbol.

[0082] In some examples, the D+U time slot may include a DL symbol without a UL symbol, or a UL symbol without a DL symbol, or an FD symbol. For example, as shown in Figure 700, D+U time slot 702 may include a DL symbol without a UL symbol, wherein a half-duplex UE (UE2) or an FD UE (UE1) may be scheduled to receive data from a base station / TRP (e.g., from panels #1 and #2 of the base station / TRP) via D+U time slot 702. In another example, D+U time slot 704 may include a D+U symbol, wherein an FD UE (UE1) may transmit data (e.g., Physical Uplink Shared Channel (PUSCH)) in the UL band (e.g., to panel #2 of the base station or TRP) and receive data (e.g., Physical Downlink Shared Channel (PDSCH)) in the DL band (e.g., from panel #1 of the base station), and a half-duplex UE (UE2) may receive data in another DL band (e.g., from panel #1 of the base station). In another example, D+U time slot 706 may include UL symbols without DL symbols, wherein a half-duplex UE (UE2) or FD UE (UE1) may be scheduled to transmit data to a base station / TRP (e.g., to panels #1 and #2 of the base station / TRP) via D+U time slot 706. For D+U time slots that include D+U symbols, the frequency bands for UL transmission and the frequency bands for DL ​​transmission may be separated by guard bands in frequency.

[0083] FD operation can be associated with multiple cells (e.g., CC), where the UE can transmit UL and / or receive DL transmissions via different cells. Figure 8A Figure 800A illustrates an example of an SBFD operation involving multiple cells (e.g., cross-cell FD operation) according to various aspects of this disclosure. The UE can perform FD operation via three cells, whereby the UE can simultaneously transmit UL and receive DL transmissions via a first cell (cell 0), a second cell (cell 1), and a third cell (cell 2). Each cell can occupy a different frequency band. For example, at time slot n, the UE can simultaneously receive DL transmissions (e.g., PDSCH) via cell 0 and cell 2 (e.g., via the first and second frequency bands) and transmit UL transmissions (e.g., PUSCH) via cell 1 (e.g., via the third frequency band); at time slot n+1, the UE can simultaneously transmit one UL transmission via cell 1, one UL transmission via cell 2, and one UL transmission via cell 3; and at time slot n+2, the UE can simultaneously receive DL transmissions via cell 0 and cell 2 and transmit UL transmissions via cell 1, and so on.

[0084] Figure 8BFigure 800B illustrates an example of an IBFD operation involving multiple cells (e.g., cross-cell FD operation) according to various aspects of this disclosure. The UE can perform FD operation via three cells, where the UE can simultaneously communicate via a first cell (cell 0), a second cell (cell 1), and a third cell (cell 2). In one example, the UE can communicate via a cell (e.g., cell 1) based on FD mode, where the UE can transmit UL data (e.g., PUSCH) via the cell and also simultaneously receive DL data (e.g., PDSCH) via that cell (e.g., using D+U time slots).

[0085] Figure 9 Figure 900 illustrates an exemplary scheduling of cross-cell FD. For cross-cell FD operations, a cell (e.g., the scheduling cell) may include scheduling of UL transmissions and / or DL ​​transmissions for other cells (e.g., the scheduled cell). For example, as shown at 902, the scheduling cell may carry a Physical Downlink Control Channel (PDCCH) scheduled to transmit a PDSCH to the UE via the scheduling cell at time slot n+3, and the PDCCH may also schedule a PUSCH to be transmitted from the UE via the scheduled cell at time slot n+3, where time slot n+3 may be an FD time slot.

[0086] The UE can also communicate with the serving cell via multiple Transmit / Receive Points (TRPs) associated with the serving cell. In other words, communication between the UE and the serving cell can be based on multiple TRP operations (from the UE's perspective). Figure 10AFigure 1000A illustrates an example of multi-TRP operation based on a single downlink control information (DCI) according to various aspects of this disclosure. A serving cell may be associated with a first TRP (e.g., TRP A) and a second TRP (e.g., TRP B), wherein the serving cell may be configured with two physical (PHY) layers, and each physical layer may be associated with a quasi-co-location (QCL) assumption (e.g., beam direction). Therefore, the UE may communicate with the serving cell via at least one of these TRPs. For example, the UE may receive a PDSCH from the serving cell via the first TRP, via the second TRP, or via both the first and second TRPs. In one example, as shown in Figure 1000A, multi-TRP operation may be based on a single DCI, wherein a TRP (e.g., the first TRP) may transmit a DCI (e.g., a PDCCH) that schedules corresponding PDSCHs to be transmitted from multiple TRPs (e.g., from both the first and second TRPs). In other words, a TRP may schedule the transmission of PDSCHs from another TRP. PDSCH scheduled by DCI can be multiplexed based on spatial division multiplexing (SDM), frequency division multiplexing (FDM), time division multiplexing (TDM), or a combination thereof. Therefore, the UE can receive PDSCH from the first TRP and the second TRP based on SDM, FDM, TDM, or a combination thereof. In some examples, multi-TRP operation based on a single DCI can be applied to the backhaul network because different PDSCH transmission schemes (e.g., different multiplexing schemes) can provide more robust or flexible communication.

[0087] In another example, multi-TRP operations can be based on multi-DCI, where each TRP can send a PDCCH to the UE that schedules its corresponding PDSCH. Figure 10B Figure 1000B illustrates examples of multi-DCI-based multi-TRP operations according to various aspects of this disclosure. In one example, a first TRP (e.g., TRP A) may send a first DCI (e.g., a first PDCCH (PDCCH 1), etc.) to the UE, which the UE schedules to send a first PDSCH (e.g., PDSCH 1) from the first TRP to the UE. Similarly, a second TRP (e.g., TRP B) may send a second DCI (e.g., a second PDCCH (PDCCH 2), etc.) to the UE, which the UE schedules to send a second PDSCH (e.g., PDSCH 2) from the second TRP to the UE. In some examples, for multi-DCI-based multi-TRP operations, a carrier aggregation (CA) framework may be utilized / used to treat different TRPs as different virtual CCs from the perspective of UE capabilities.

[0088] In some scenarios, for single-cell operation with two uplink carriers or for operation with carrier aggregation, if the total UE transmit power transmitted on the serving cell’s PUSCH, PUCCH, Physical Random Access Channel (PRACH), and / or Sounding Reference Signal (SRS) within the frequency range of the corresponding transmission timing “i” will exceed P_cmax(i) (e.g., maximum UE transmitter power), the UE can be configured to transmit allocated power to the PUSCH, PUCCH, PRACH, and / or SRS based on a defined priority order.

[0089] Figure 11 Figure 1100 illustrates an example of transmit power backoff priority ordering according to various aspects of this disclosure. A UE may be configured with two uplink carriers (e.g., uplink carrier 1 and uplink carrier 2), which the UE may use to transmit PUSCH, PUCCH, PRACH, and / or SRS, etc. As shown at 1102, if the total UE transmit power within the frequency range of a corresponding transmission timing “i” would exceed the configured / defined maximum UE transmitter power (e.g., P_cmax(i)), the UE may apply priority order 1104 to prioritize the transmit power such that the total UE transmit power transmitted on the serving cell within that frequency range is less than or equal to the configured / defined maximum UE transmitter power for that frequency range in that transmission timing. In one example, as shown at 1106, priority order 1104 may indicate the power allocation priority of the following: (i) PRACH transmission on PCell > (ii) PUCCH or PUSCH transmission with a higher priority index > (iii) PUCCH or PUSCH transmission with the same priority index > (iv) PUCCH transmission with HARQ-ACK information and / or SR and / or LRR, or PUSCH transmission with HARQ-ACK information > (v) PUCCH transmission with CSI, or PUSCH transmission with CSI > (vi) PUSCH transmission without HARQ-ACK information or CSI, and for a type 2 random access procedure, PUSCH transmission on PCell > (vii) SRS transmission, where non-periodic SRS has a higher priority than semi-persistent and / or periodic SRS, or PRACH transmission on a serving cell other than PCell, etc., where (i) may have the highest power allocation priority and (vii) may have the lowest power allocation priority.

[0090] For example, if a first uplink carrier (e.g., uplink carrier 1) is scheduled using a PRACH transmission on a PCell during a transmission timing, and a second uplink carrier (e.g., uplink carrier 2) is scheduled using a PUCCH transmission with channel state information (CSI), the UE can prioritize its power allocation for the first uplink carrier (e.g., PRACH transmission) over its power allocation for the second uplink carrier (e.g., PUCCH transmission) based on priority order 1104. For example, a PRACH transmission (e.g., as shown at (i)) can have a higher transmission priority than a PUCCH transmission with CSI (e.g., as shown at (v)). In other words, the UE can back off the power used for transmitting a PUCCH transmission with CSI such that the total UE transmission power does not exceed the maximum UE transmitter power configured / defined for that transmission timing (e.g., P_cmax(i)).

[0091] In another example, if a first uplink carrier (e.g., uplink carrier 1) is scheduled using a PUSCH transmission without CSI and a second uplink carrier (e.g., uplink carrier 2) is scheduled using a PUSCH transmission with CSI, the UE can prioritize power allocation for the second uplink carrier over power allocation for the first uplink carrier based on priority order 1104. For example, a PUSCH transmission with CSI (e.g., as shown at (v)) has a higher transmission priority than a PUSCH transmission without CSI (e.g., as shown at (vi)). In other words, the UE can back off the power used for transmitting PUSCH transmissions without CSI such that the total UE transmission power does not exceed the maximum UE transmitter power configured / defined for that transmission timing (e.g., P_cmax(i)).

[0092] In some examples, if the first uplink carrier and the second uplink carrier have the same transmission priority, the UE can be further configured to prioritize the transmission power of the first uplink carrier and the second uplink carrier based on whether the transmission is on a primary cell or a secondary cell, and / or based on whether the transmission includes a PUCCH or whether the uplink carrier is a non-supplementary UL carrier, etc. In other words, the UE can apply additional power priority ranking rules. For example, in the case of the same priority order, and for operations with carrier aggregation, the UE can be configured to prioritize the power allocation of transmissions on the primary cell (e.g., PCell) in the primary cell group (MCG) or the primary cell (e.g., PSCell) in the secondary cell group (SCG) over the power allocation of transmissions on the secondary cell (SCell). For example, the first uplink carrier can be scheduled to transmit a PUCCH transmission with CSI on the primary cell, and the second uplink carrier can be scheduled to transmit a PUSCH transmission with CSI on the secondary cell. Since PUCCH transmissions with CSI can have the same transmit power priority as PUSCH transmissions with CSI (e.g., based on priority order 1104(v)), the UE can prioritize its transmit power for the first uplink carrier over its transmit power for the second uplink carrier (e.g., prioritizing the transmit power of PUCCH transmissions with CSI), because the first uplink carrier (e.g., PUCCH transmissions with CSI) will be transmitted on the primary cell, while the second uplink carrier (e.g., PUSCH transmissions with CSI) will be transmitted on the secondary cell. In other words, the UE can back off the power used for transmitting PUSCH transmissions with CSI, ensuring that the total UE transmit power does not exceed the maximum UE transmitter power configured / defined for that transmission timing.

[0093] In another example, with the same priority order, and for operation with two UL carriers, the UE can prioritize the power allocation for transmissions on the UL carriers configured to transmit PUCCHs on those UL carriers. However, if no PUCCH is configured for either of the two UL carriers, the UE can prioritize the power allocation for transmissions on non-supplementary UL carriers. For example, if the first UL carrier is scheduled to transmit a PUCCH with CSI, and the second UL carrier is scheduled to transmit a PUSCH with CSI (e.g., both transmissions have the same power allocation priority), the UE can prioritize the power allocation for the first UL carrier since the first UL carrier includes the PUCCH transmission. In other words, the UE can back off the power used for transmitting a PUSCH with CSI so that the total UE transmission power does not exceed the maximum UE transmitter power configured / defined for that transmission timing. In another example, if both UL carriers are used to transmit a PUSCH with CSI, the UE can prioritize the power allocation for non-supplementary UL carriers in the first and second UL carriers.

[0094] When a UE transmits multiple UL carriers based on CA, the UE can set the maximum output power of the serving cell and the total maximum output power. In one example, for uplink carrier aggregation based on in-band consecutive CA (e.g., CC / UL carriers are adjacent to each other in the frequency band), the UE can set its maximum output power P configured for the serving cell c. CMAX,c and its configured total maximum output power P CMAX The maximum output power P configured on the serving cell c. CMAX,c The following settings are available:

[0095] P CMAX_L,c ≤P CMAX,c ≤P CMAX_H,c ,in

[0096] P CMAX_L,c =MIN{P EMAX,c -ΔT C,c ,(P 功率等级 -ΔP 功率等级 )-MAX(MAX(MPR c +ΔMPR c A-MPR c )+ΔT IB,c +ΔT C,c +ΔT RxSRS P-MPR c )},and

[0097] P CMAX_H,c =MIN{PEMAX,c ,P 功率等级 -ΔP 功率等级},

[0098] Where P EMAX,c It can be a value given by the additionalPmax field of the p-Max information element (IE) or the NR-NS-PmaxList IE; P 功率等级 The maximum UE power can be specified by a table or predefined; ΔP 功率等级 Depending on the UE's power level (e.g., when indicating a P-max of 23 dBm or lower, for a UE with power level 2 capability, ΔP), 功率等级 = 3dB, or for a UE with power level 1.5 capability, ΔP 功率等级 =6dB, etc.); ΔT IB,c It can be an additional tolerance for serving cell c; when certain conditions apply to serving cell c, ΔT C,c It can be based on a value between 0dB and 1.5dB; MPR c This could be the maximum power back-off (MPR) of the serving cell C, which can be predefined based on a table; A-MPR c This could be the Additional Maximum Power Backoff (A-MPR) of serving cell C, which can be predefined based on a table or a set of rules; the ΔMPR of serving cell C. c It can be a value specified based on a table or a set of rules; ΔT RxSRS It can be applied based on whether the UE transmits SRS and / or the transmission location of SRS (e.g., first SRS port, second SRS port, DL carrier, etc.); P-MPR c It can be used for power management maximum power backoff to comply with applicable electromagnetic energy absorption specifications and / or to address unwanted transmissions, etc. In some examples, P-MPRc can be used in P... CMAX,c The equation introduces a feature that allows the UE to report the maximum available output transmission power to the base station, which can then use this information for scheduling decisions.

[0099] Similarly, the UE can configure the total maximum output power P CMAX Set in P CMAX_L ≤P CMAX ≤P CMAX_H For example, for UL-band continuous carrier aggregation, if the same time slot pattern is used in all aggregated serving cells:

[0101] P CMAX_H =MIN{10log 10 ∑p EMAX,c ,P EMAX,CA ,P 功率等级,CA},

[0102] Where p EMAX,c It can be P EMAX,c The linear value of P is given by the IE P-Max of the serving cell c; 功率等级,CA It can be the maximum UE power specified based on a table or a set of rules; MPR and A-MPR can be the maximum power backoff and additional maximum power backoff defined based on a table or a set of rules, respectively; ΔT IB,c It can be an additional tolerance of the serving cell; P-MPR can be a power management term for the UE (e.g., there can be a power management term for the UE, denoted as P-MPR, and P-MPR...). c =P-MPR); ΔT C It can be the highest value ΔT among all serving cells c. C,c ;ΔT RxSRS It can be the highest value among all serving cells c; P EMAX,CA It can be a value indicated by p-NR-FR1 or p-UE-FR1, etc. If both fields exist, the smaller value shall prevail.

[0103] In another example, for UL carrier aggregation based on in-band non-contiguous CA (e.g., at least one CC / UL carrier is separated from or not adjacent to another CC / UL carrier within the frequency band), the UE can set its maximum output power P configured for the serving cell c. CMAX,c and its configured total maximum output power P CMAX The maximum output power P configured on the serving cell c. CMAX,c The following settings are available:

[0104] P CMAX_L,c ≤P CMAX,c ≤P CMAX_H,c ,in

[0105] P CMAX_L,c =MIN{P EMAX,c -ΔT C,c ,(P 功率等级 -ΔP 功率等级 )-MAX(MAX(MPR c+ΔMPR c A-MPR c )+ΔT IB,c +ΔT C,c +ΔT RxSRS P-MPR c )},and

[0106] P CMAX_H,c =MIN{P EMAX,c ,P 功率等级 -ΔP 功率等级},

[0107] Where P EMAX,c It can be a value given by the additionalPmax field of p-Max IE or NR-NS-PmaxList IE; P 功率等级 The maximum UE power can be specified by a table or predefined; ΔP 功率等级 Depending on the UE's power level (e.g., when indicating a P-max of 23 dBm or lower, for a UE with power level 2 capability, ΔP), 功率等级 = 3dB, or for a UE with power level 1.5 capability, ΔP 功率等级 =6dB, etc.); ΔT IB,c It can be an additional tolerance for serving cell c; when certain conditions apply to serving cell c, ΔT C,c It can be based on a value between 0dB and 1.5dB; MPR c It can be the MPR of the serving cell c, which can be predefined based on a table or a set of rules; A-MPR c It can be the A-MPR of serving cell c, which can be predefined based on a table; the ΔMPR of serving cell c. c It can be a value specified based on a table or a set of rules; ΔT RxSRS It can be applied based on whether the UE transmits SRS and / or the transmission location of SRS (e.g., first SRS port, second SRS port, DL carrier, etc.); P-MPR c It can be used for power management maximum power backoff to comply with applicable electromagnetic energy absorption specifications and / or to address unwanted transmissions, etc. In some examples, P-MPRc can be used in P... CMAX,c The equation introduces a feature that allows the UE to report the maximum available output transmission power to the base station, which can then use this information for scheduling decisions.

[0108] Similarly, the UE can configure the total maximum output power P CMAX Set in P CMAX_L ≤P CMAX ≤P CMAX_HFor example, for in-band non-contiguous carrier aggregation within the UL band, if the same time slot pattern is used in all aggregated serving cells:

[0109] P CMAX_L =MIN{10log 10 ∑p EMAX,c -ΔT C ,P EMAX,CA ,P 功率等级,CA -MAX(MAX(MPR c A-MPR c )+ΔT IB,c +ΔT C +ΔT RxSRS P-MPR c )},and

[0110] P CMAX_H =MIN{10log 10 ∑p EMAX,c ,P EMAX,CA ,P 功率等级,CA},

[0111] Where p EMAX,c It can be P EMAX,c The linear value of P can be given by the IE P-Max of the serving cell c; 功率等级,CA The maximum UE power can be specified based on a table or a set of defined rules; MPR and A-MPR can be maximum power backoff and additional maximum power backoff, respectively, defined based on a table or a set of rules; ΔT IB,c It can be an additional tolerance for the service cell; MPR c It can be the MPR of the serving cell c, which can be predefined based on a table; A-MPR c It can be the A-MPR of the serving cell c, which can be predefined based on a table or a set of rules; the P-MPR can be a power management item for the UE (for example, there can be a power management item for the UE, denoted as P-MPR, and P-MPR...). c =P-MPR); ΔT C It can be the highest value ΔT among all serving cells c. C,c ;ΔT RxSRS It can be the highest value among all serving cells c; P EMAX,CA It can be a value indicated by p-NR-FR1 or p-UE-FR1, etc. If both fields exist, the smaller value shall prevail.

[0112] In one example, a power management maximum output power backoff (e.g., P-MPR) can be configured for the UE. f,c The UE can apply P-MPR to carrier f of serving cell c. f,cThis is to ensure compliance with applicable electromagnetic power density exposure specifications, thereby handling unwanted transmissions and / or self-sensitivity degradation specifications when transmitting simultaneously on multiple RATs; and / or to ensure compliance with applicable electromagnetic power density exposure specifications when using proximity detection, thereby handling such specifications that specify lower maximum output power. Similarly, P-MPR f,c Available in P CMAX,f,c The equation introduces a feature that allows the UE to report the maximum available output transmit power to the base station. This information can then be used by the base station for scheduling decisions.

[0113] In some examples, the maximum output power back-off of the UE with continuous CA in band (e.g., MPR, MPR) c (etc.) can be based on the length of the contiguous resource block (RB) used for transmission in the cell (LCRB) and / or the lowest RB index of the RBs transmitted in the cell. In other words, the in-band contiguous UL CA MPR can be based on whether the RB allocation of the UL CA is classified as an internal RB allocation or an external RB allocation. Table 1 below shows examples of MPRs allowed for UE power class 3CA and bandwidth classes B and C.

[0114]

[0115] Table 1 - Exemplary Continuous RB Allocation for Power Level 3

[0116] In one example, for CA bandwidth class B and bandwidth class C with consecutive RB allocations, the following parameters can be defined to specify the RB allocation range for internal and external RB allocations (e.g., to determine whether an RB allocation is internal or external). If L CRB1 =0 or L CRB2 =0, or (L CRB1 ≠0 and L CRB2 δ≠0, RB Start1 +L CRB1 =N RB1 And RB Start2 If = 0), then the RB allocation can be continuous, where RB = 0. Start1 L CRB1 and N RB1 It can be used for the first component carrier (CC1), RB Start2 L CRB2 and N RB2 It can be used for the second component carrier (CC2), and CC1 can be a component carrier with a lower frequency. In continuous CA, continuous allocation can be internal allocation, provided that:

[0117] RB Start,Low ≤RB Start_CA ≤RB Start,High And NRB_alloc ≤ceil(N RB,agg / 2),

[0118] in

[0119] RB Start,Low =max(1,floor(N) RB_alloc / 2))

[0120] RB Start,High =N RB,agg -RB Start,Low -N RB,alloc ,

[0121] in

[0122] N RB_alloc =L CRB1 ·2^μ1+L CRB2 ·2^μ2

[0123] N RB_alloc =(N RB1 -RB Start1 )·2^μ1+(RB Start2 +L CRB2 )·2^μ2,

[0124] N RB,agg =N RB1 ·2^μ1+N RB2 ·2^μ2.

[0125] If L CRB1 =0, then RB Start_CA =N RB1 ·2^μ1+RB Start2 ·2^μ2,

[0126] If L CRB1 >0, then RB Start_CA =RB Start1 ·2^μ1.

[0127] A contiguous allocation that is not internally contiguous can be externally contiguous.

[0128] Figure 12Figure 1200 illustrates an example of determining whether a contiguous allocation is an internal or external allocation according to various aspects of this disclosure. As shown at 1202, whether a contiguous RB allocation is an internal or external RB allocation may depend on the length of the contiguous resource block (e.g., LCRB value) and the lowest RB index (e.g., RB start value) of the RBs transmitted associated with the contiguous RB allocation. For example, as shown at 1204, a contiguous RB allocation may be considered an internal RB allocation if it has an LCRB value and an RB start value that fall within the internal RB allocation region defined by the above equation. In another example, as shown at 1206, a contiguous RB allocation may be considered an external RB allocation if it has an LCRB value and an RB start value that fall within the external RB allocation region. Then, based on determining whether a contiguous RB allocation is an internal or external RB allocation, the MPR applicable to the UE may be further determined based on bandwidth level, modulation, and / or UE power level. For example, as shown in Figure 12 As shown at 1208, and based on Table 1 above, if the UE is associated with UE power class 3CA and bandwidth class B, the modulation used for transmission is based on Direct Fourier Transform Extended OFDM (DFT-s-OFDM) 64 Quadrature Amplitude Modulation (QAM), and the RB allocation for this transmission is classified as an external RB allocation, then the MPR that the UE can apply to the current transmission can be 4.0 dB. In another example, as in Figure 12 As shown at 1210, and based on Table 1 above, if the UE is associated with UE power class 3CA and bandwidth class B, the modulation used for transmission is based on cyclic prefix OFDM (CP-OFDM) 256QAM, and the RB allocation for the transmission is classified as internal RB allocation, then the MPR that the UE can apply to the transmission can be 6.5dB.

[0129] In some examples, the MPR value can be independent of the UE declaring a dual amplifier (2PA) architecture (e.g., the UE is capable of transmitting using two power amplifiers). Therefore, as shown in Table 1, bandwidth class C can include a higher MPR value compared to bandwidth class B to allow the UE to declare 2PA and overcome excessive reverse intermodulation distortion (RIMD) effects (e.g., RIMD can occur when a signal from one transmitter couples to the output port of a nearby transmitter, and vice versa). In some examples, the internal MPR (e.g., an MPR value based on internal RB allocation) can be dominated by vector amplitude error (EVM), and the external MPR (e.g., an MPR value based on external RB allocation) can be dominated by spectrum transmission template (SEM) and adjacent channel leakage ratio (ACLR). Furthermore, the RB start and LCRB positions (e.g., as shown at 1204 and 1206) can be functions of the RB start and associated subcarrier spacing (SCS) of the two CCs (e.g., two UL carriers), and μ can be an index as a function of SCS.

[0130] Figure 13 This is a communication flow 1300 illustrating an exemplary overall process by which a UE determines whether to apply a power allocation priority ordering rule to multiple transmissions (e.g., UL transmissions) according to various aspects of this disclosure. The numbers associated with communication flow 1300 do not specify a particular time order and are used only as a reference to communication flow 1300.

[0131] As shown at 1306 and 1308, UE 1302 can receive from base station 1304 a first PDCCH (PDCCH 1) and a second PDCCH (PDCCH 2) that schedule a first UL transmission (UL Tx1) and a second UL transmission (UL Tx 2), respectively. In some examples, UE 1302 can receive different PDCCHs on different cells (such as on a primary cell and on one or more secondary cells). For example, UE 1302 can receive the first PDCCH on the primary cell, and UE 1302 can receive the second PDCCH on a secondary cell, and so on.

[0132] At 1310, UE 1302 can determine P based on MPR, A-MPR, and P-MPR. CMAX,c (For example, the maximum UE output power of serving cell c) and P CMAX The lower limit of P (e.g., maximum UE output power). In other words, the UE can determine P based on the following equation. CMAX_L,c and P CMAX_L :

[0133] P CMAX_L =MIN{10log 10 ∑p EMAX,c -ΔTC ,P EMAX,CA ,P 功率等级,CA -MAX(MAX(MPR,A-MPR)+ΔT IB,c +ΔT C +DT RxSRS P-MPR c )},and

[0134] P CMAX_L,c =MIN{P EMAX,c -ΔT C,c ,(P 功率等级 -ΔP 功率等级 )-MAX(MAX(MPR c A-MPR c )+ΔTIB,c+ΔTC,c+ΔTRxSRS,P-MPR c )}.

[0135] At 1312, UE 1302 may determine P based at least in part on available information regarding the first UL transmission and the second UL transmission and / or on a set of pre-configured rules. CMAX,c and P CMAX The value of . In other words, the UE can set its maximum output power P configured for the serving cell c based on the following equation. CMAX,c and its configured total maximum output power P CMAX :P CMAX_L,c ≤P CMAX,c ≤P CMAX_H,c And P CMAX_L ≤P CMAX ≤P CMAX_H , where P CMAX_H,c =MIN{P EMAX,c ,P 功率等级 -ΔP 功率等级}, and P CMAX_H =MIN{10log 10 ∑p EMAX,c ,P EMAX,CA ,P 功率等级,CA}

[0136] At position 1314, P is determined in UE 1302. CMAX,c and P CMAX After the value, if the total UE transmit power transmitted on the serving cell within the frequency range of the corresponding transmission timing "i" exceeds P, CMAX (i) Then UE 1302 can apply power allocation priority sorting rules to the first UL transmission and the second UL transmission, such as combining Figure 11 As described (e.g., priority order 1104 may be applied to the UE).

[0137] At points 1316 and 1318, if UE 1302 applies a power allocation priority ordering rule, then UE 1302 can transmit a first UL transmission and a second UL transmission based on the power allocation priority ordering rule, such as combining... Figure 11 As described. For example, the transmission power of at least one of the first UL transmission and the second UL transmission can be reverted. On the other hand, if the total UE transmission power transmitted on the serving cell within the frequency range of the corresponding transmission timing "i" will not exceed P. CMAX (i) UE 1302 may transmit the first UL transmission and the second UL transmission without applying power allocation priority ordering rules (e.g., without backing down the transmission power of both the first UL transmission and the second UL transmission). Similarly, although communication flow 1300 shows UE 1302 transmitting the first UL transmission and the second UL transmission to base station 1304, UE 1302 may also transmit different UL transmissions to different TRPs of base station 1304. For example, UE 1302 may transmit the first UL transmission to the first TRP of base station 1304 (e.g., the TRP transmitting the first PDCCH), and UE 1302 may transmit the second UL transmission to the second TRP of base station 1304 (e.g., the TRP transmitting the second PDCCH), and so on. In another example, UE 1302 may transmit different UL transmissions on different cells (such as on a primary cell and on one or more secondary cells). For example, UE 1302 may transmit the first UL transmission on a primary cell, and UE 1302 may transmit the second UL transmission on a secondary cell, and so on.

[0138] The aspects presented herein can improve wireless communication for FD devices or FD-capable devices (e.g., UEs operating in FD mode) by enabling full-duplex devices to apply power backoff to FD operations. The aspects presented herein can enable FD devices to determine whether to apply an FD-specific MPR (e.g., when UL transmissions at least partially overlap with downlink transmissions in time) and / or whether to apply power allocation priority ordering rules to transmissions in FD transmissions (e.g., UL transmissions and / or SL transmissions), etc.

[0139] In one aspect of this disclosure, a UE-specific MPR (e.g., FD-MPR, FD-MPR) can be defined for the UE. c(etc.), wherein the MPR specific to FD mode / operation (hereinafter referred to as "FD-specific MPR") can be a value or a set of values ​​that takes into account the power backoff specified in FD operations in neighboring cells. For example, if a UE (e.g., a UE with FD capability, an FDUE, etc.) is scheduled using multiple UL transmissions and at least one DL reception that overlap at least partially in time, the UE can apply an FD-specific MPR to at least one UL transmission in the UL transmissions to reduce interference or potential interference that the UL transmissions may cause to at least one DL reception.

[0140] Figure 14 Figure 1400 illustrates an example of applying an FD-specific MPR to FD operations according to various aspects of this disclosure. As shown at 1402, the UE can be scheduled to transmit a first UL transmission 1404 on a first secondary cell (SCell 0) and a second UL transmission 1406 on a primary cell (PCell), and the UE can be further scheduled to receive a DL reception 1408 on a second secondary cell (SCell 1), wherein the transmissions in the first UL transmission 1404 and the second UL transmission 1406 and the reception of the DL reception 1408 can be concurrent (e.g., simultaneous) or at least partially overlap in time, such as in combination. Figure 8A and Figure 8B As described. In one example, since the second UL transmission 1406 may be closer to the DL reception 1408 in terms of frequency compared to the first UL transmission 1408, the UE can be configured to apply an FD-specific MPR to the second UL transmission 1406 to avoid or reduce the possibility of the second UL transmission 1406 interfering with the DL reception 1404. In one example, an FD-specific MPR (e.g., FD-MPR) can be defined for each cell. c Furthermore, the FD-specific MPR (e.g., the value of the MPR) can take into account whether the corresponding UL transmission is associated with an internal RB allocation or an external RB allocation, such as combining... Figure 12 As described.

[0141] In one aspect, the UE can be configured to apply FD-specific MPR (e.g., FD-MPR, FD-MPR) in FD mode / operation. c (etc.), regardless of whether a DL grant is received. For example, since a UE in FD mode (e.g., FD configuration is active) may or may not receive a DL grant (e.g., FD slots may include UL scheduling but not DL scheduling), if the UE schedules using one or more UL transmissions but not using at least one DL reception (e.g., no DL grant / scheduling), the UE can still apply an FD-specific MPR to at least one UL transmission. In some scenarios, such as in Figure 14As shown at 1402, the UE may receive UL grants and / or DL ​​grants (e.g., PDCCHs) at different times. Therefore, a UE in FD mode may not know whether a DL grant is currently scheduled to be dispatched with at least one UL grant. For example, as shown at 1402, the UE may receive two PDCCHs, one scheduling a first UL transmission 1404 and the other scheduling a second UL transmission 1406, before receiving a PDCCH that schedules a DL reception 1408. Therefore, the advantage of enabling the UE to apply FD-specific MPR regardless of the presence of a DL grant during FD mode is that the UE can determine whether to apply MPR to at least one UL transmission in the UL transmissions before receiving or confirming the presence of a DL grant. Alternatively, if at least one DL grant exists (e.g., at least one DL reception overlapping with a UL transmission), the UE can be configured to apply FD-specific MPR (e.g., FD-MPR, FD-MPR) in FD mode / operation. c (etc.), otherwise the UE may not apply FD-specific MPR, or may skip applying FD-specific MPR. For example, return to reference Figure 14 If the FD operation includes at least one DL reception (e.g., DL reception 1408), the UE may apply the FD-specific MPR. However, if there is no scheduled DL reception, the UE may not apply the FD-specific MPR.

[0142] Figure 15 This is a communication flow 1500 illustrating an example of a UE in FD mode, under various aspects of this disclosure, determining whether to apply a power allocation priority ordering rule to multiple transmissions (e.g., UL transmissions) considering self-interference. The numbers associated with communication flow 1500 do not specify a particular time order and are used only as a reference to communication flow 1500.

[0143] As shown at 1506, 1508, and 1510, UE 1502 may receive from base station 1504 a first PDCCH (PDCCH 1), a second PDCCH (PDCCH 2), and a third PDCCH (PDCCH 3) for scheduling a first UL transmission 1507 (UL Tx 1), a second UL transmission 1509 (UL Tx 2), and a DL reception 1511, respectively. Although communication flow 1500 shows the receipt of three PDCCHs from base station 1504 for scheduling the first UL transmission 1507, the second UL transmission 1509, and the DL reception 1511, in some examples, the same PDCCH may be used to schedule the first UL transmission 1507, the second UL transmission 1509, and / or the DL reception 1511 (e.g., PDCCH 1, PDCCH 2, and / or PDCCH 3 may be the same PDCCH). In some examples, UE 1502 may receive different PDCCHs on different cells (such as on a primary cell and on one or more secondary cells). For example, UE 1502 may receive a first PDCCH on the primary cell, a second PDCCH on the first secondary cell (e.g., SCell 0), and a third PDCCH on the second secondary cell (e.g., SCell 1), and so on.

[0144] At 1512, UE 1502 can determine P based on MPR, A-MPR, P-MPR, and FD-MPR. CMAX,c (For example, the maximum UE output power of serving cell c) and P CMAX The lower limit of P (e.g., maximum UE output power). In other words, the UE can determine P based on the following equation. CMAX_L,c and P CMAX_L :

[0145] P CMAX_L =MIN{10log 10 ∑p EMAX,c -ΔT C ,P EMAX,CA ,P 功率等级,CA -MAX(MAX(MPR,A-MPR,FD-MPR)+ΔT IB,c +ΔT C +DT RxSRS P-MPR c )},and

[0146] P CMAX_L,c =MIN{P EMAX,c -ΔT C,c ,(P 功率等级 -ΔP 功率等级 )-MAX(MAX(MPR c A-MPR cFD-MPR c )+ΔTIB,c+ΔTC,c+ΔTRxSRS,P-MPR c )}.

[0147] In some examples, such as combination Figure 14 As described, when UE 1502 determines P CMAX,c and P CMAX When the lower limit is reached, should UE1502 include FD-specific MPR (e.g., FD-MPR and / or FD-MPR)? c This may depend on the presence of at least one DL authorization (e.g., DL reception 1511). For example, UE 1502 may be configured to send an application FD-specific MPR to one or more ULs regardless of the presence of at least one DL authorization, or UE 1502 may be configured to send an application FD-specific MPR to one or more ULs if at least one DL authorization is present, and so on.

[0148] At 1513, UE 1502 may determine P based at least in part on available information regarding the first UL transmission 1507, the second UL transmission 1509, and the DL reception 1511 and / or on a set of pre-configured rules. CMAX,c and P CMAX The value of . In other words, the UE can set its maximum output power P configured for the serving cell c based on the following equation. CMAX,c and its configured total maximum output power P CMAX :P CMAX_L,c ≤P CMAX,c ≤P CMAX_H,c And P CMAX_L ≤P CMAX ≤P CMAX_H , where P CMAX_H,c =MIN{P EMAX,c ,P 功率等级 -ΔP 功率等级}, and P CMAX_H =MIN{10log 10 ∑p EMAX,c ,P EMAX,CA ,P 功率等级,CA UE 1502 can also determine the transmit power for each transmission (e.g., each UL transmission in a UL transmission). In some examples, as shown at 1520, after receiving the schedule of the first UL transmission 1507, the second UL transmission 1509, and the DL reception 1511 (e.g., after receiving the first PDCCH, the second PDCCH, and the third PDCCH), UE 1502 can determine the transmit power. CMAX,c and P CMAXThe value of . In other examples, such as at 1522, after receiving the schedule of the first UL transmission 1507 and the second UL transmission 1509 but before receiving the schedule of the DL reception 1511 (e.g., after receiving the first PDCCH and the second PDCCH but before receiving the third PDCCH), UE 1502 can determine P. CMAX,c and P CMAX The value of .

[0149] In some examples, UE 1502 may determine P based at least in part on its ability to eliminate self-interference and / or one or more self-interference threshold specifications, etc. CMAX,c and P CMAX The value of P. For example, UE 1502 may determine P based on the amount of interference that may be caused to DL reception, the ability of UE 1502 to eliminate self-interference, and / or self-interference threshold specifications (e.g., configured or defined for UE 1502). CMAX,c Weights. Then, the UE 1502 can determine the P for each cell based on the determined weights. CMAX,c .

[0150] At position 1514, P is determined in UE 1502. CMAX,c and P CMAX After the value, if the total UE transmit power transmitted on the serving cell within the frequency range of the corresponding transmission timing "i" exceeds P, CMAX (i) Then UE 1502 can apply power allocation priority sorting rules to the first UL transmission 1507 and the second UL transmission 1509, such as combining Figure 11 As described (e.g., the UE may apply priority order 1104). For example, if the transmit power determined on the first cell (e.g., for transmitting the first UL transmit 1507) plus the transmit power determined on the second cell (e.g., for transmitting the second UL transmit 1509) exceeds the determined P CMAXThen the UE may apply a power allocation priority sorting rule, which may indicate the power allocation priority of the following items: (i) PRACH transmission on PCell > (ii) PUCCH or PUSCH transmission with a higher priority index > (iii) PUCCH or PUSCH transmission with the same priority index > (iv) PUCCH transmission with HARQ-ACK information and / or SR and / or LRR, or PUSCH transmission with HARQ-ACK information > (v) PUCCH transmission with CSI, or PUSCH transmission with CSI > (vi) PUSCH transmission without HARQ-ACK information or CSI, and for a type 2 random access procedure, PUSCH transmission on PCell > (vii) SRS transmission, where non-periodic SRS has a higher priority than semi-persistent and / or periodic SRS, or PRACH transmission on the serving cell other than PCell, etc. (e.g., (i) may have the highest power allocation priority, and (vii) may have the lowest power allocation priority).

[0151] At points 1516 and 1518, if UE 1502 applies a power allocation priority ordering rule to the first UL transmission 1507 and the second UL transmission 1509, then UE 1502 can transmit the first UL transmission 1507 and the second UL transmission 1509 based on the power allocation priority ordering rule, such as by combining... Figure 11 As described. For example, the transmission power of at least one of the first UL transmission 1507 and the second UL transmission 1509 can be reverted. On the other hand, if the total UE transmission power transmitted on the serving cell within the frequency range of the corresponding transmission timing "i" will not exceed P. CMAX(i) UE 1502 may transmit the first UL transmission 1507 and the second UL transmission 1509 without applying power allocation priority ordering rules (e.g., without downgrading the transmission power of both the first UL transmission 1507 and the second UL transmission 1509). Similarly, although communication flow 1500 shows UE 1502 transmitting the first UL transmission 1507 and the second UL transmission 1509 to base station 1504, UE 1502 may also transmit different UL transmissions to different TRPs of base station 1504. For example, UE 1502 may transmit the first UL transmission 1507 to the first TRP of base station 1504 (e.g., the TRP transmitting the first PDCCH), and UE 1502 may transmit the second UL transmission 1509 to the second TRP of base station 1504 (e.g., the TRP transmitting the second PDCCH), and so on. In another example, UE 1502 may transmit different UL transmissions on different cells (such as on a primary cell and on one or more secondary cells). For example, UE 1502 can send a first UL transmission 1507 on the primary cell, and UE 1502 can send a second UL transmission 1509 on the secondary cell, and so on.

[0152] At 1524, UE 1502 may receive DL reception 1511 from base station 1504 (or the TRP of that base station), wherein DL reception 1511 may at least partially overlap in time with at least one of first UL transmission 1507 or second UL transmission 1509, as shown at 1526. For example, UE 1502 may transmit first UL transmission 1507 and second UL transmission 1509 and receive DL reception 1511 in the FD time slot.

[0153] In another aspect of this disclosure, for in-band CA, if UE 1502 applies a power allocation priority sorting rule to multiple UL transmissions (e.g., at 1514) and at least two UL transmissions have the same priority order (e.g., the first UL transmission 1507 and the second UL transmission 1509 have the same power allocation priority), UE 1502 may further apply an additional power priority sorting rule to UL transmissions with the same priority.

[0154] Figure 16Figure 1600 illustrates an example of the in-band CA power priority ordering that a UE can apply in FD mode when multiple UL transmissions have the same power allocation priority, according to various aspects of this disclosure. In one example, as shown at 1602, if multiple UL transmissions have the same power allocation priority, the UE can provide a higher power allocation priority to the primary cell. In other words, a higher power allocation priority can be provided to UL transmissions on the primary cell compared to UL transmissions on the secondary cell. For example, as shown at 1604, when a first UL transmission 1507 is transmitted on a secondary cell (e.g., SCell 0) and a second UL transmission 1509 is transmitted on a primary cell (e.g., PCell), UE 1502 can provide a higher power allocation priority to the second UL transmission 1509. In some examples, if UE 1502 calculates P... CMAX and / or P CMAX,c When applying FD-specific MPR (e.g., in UE 1502 to determine P) CMAX and / or P CMAX,c If the value is considered when taking into account FD-specific MPR, then UE 1502 can be configured to apply such configuration (e.g., the rule shown at 1602). If P is calculated in UE 1502 CMAX and / or P CMAX,c If FD-specific MPR is not applied, then UE 1502 may not apply this configuration.

[0155] In another example, as shown at 1606, if multiple UL transmissions have the same power allocation priority, the UE can assign a higher power allocation priority to the primary or secondary cell based on which cell is likely to cause less interference to DL reception. In other words, power priority can be assigned to cells that are further away from DL reception, such as in frequency and / or spatial beam direction. For example, as shown at 1604, since the second UL transmission 1509 is closer to DL reception in terms of frequency than the first UL transmission 1507, UE 1502 can assign a higher power allocation priority to the first UL transmission 1507 (e.g., to SCell0) and can back down the transmission power of the second UL transmission 1509. In other words, even if the UL transmission may not be on the primary cell, UE 1502 can assign a higher power allocation priority to the UL transmission that causes less self-interference compared to other UL transmissions. In some examples, if UE 1502 calculates P... CMAX and / or P CMAX,c At that time, FD-specific MPR was not applied to the primary cell (e.g., when UE 1502 determined the P of the primary cell). CMAX and / or P CMAX,cIf the value is not considered when calculating P (without taking FD-specific MPR into account), then UE 1502 can be configured to apply such a configuration (e.g., the rule shown at 1606). Otherwise, if P is calculated in UE 1502... CMAX and / or P CMAX,c If UE 1502 applies an FD-specific MPR to the primary cell, then UE 1502 can apply this configuration. In other words, if UE 1502 applies an FD-specific MPR to the primary cell, then UE 1502 can apply the rule indicated at 1602; and if UE 1502 does not apply an FD-specific MPR to the primary cell, then UE 1502 can apply the rule indicated at 1606, and so on.

[0156] In another aspect of this disclosure, when a UE simultaneously transmits multiple UL transmissions and receives at least one DL reception in a CC (e.g., UL transmissions and DL receptions at least partially overlap in time), if a UL-DL priority ordering rule (e.g., a transmission or communication priority rule different from a power allocation priority rule) is configured for UL transmissions and DL transmissions, the UE can determine the power allocation priority of the multiple UL transmissions at least partially based on the priority associated with the at least one DL transmission. For example, UL transmissions can be configured to have a higher communication priority than DL receptions, allowing the UE to prioritize UL transmissions over DL receptions.

[0157] Figure 17 Figure 1700 illustrates an example of applying power allocation priority ordering to multiple UL transmissions in a CC based at least in part on UL-DL priorities associated with concurrent DL transmissions in the CC, according to various aspects of this disclosure. UE 1702 (e.g., UE 1502) (which may be an FD UE with multiple antenna panels) can communicate with base station 1704 (e.g., base station 1504) via a first TRP 1706 (TRP A) and a second TRP 1708 (TRP B), such as in combination with... Figure 10A , Figure 10B and Figure 15 As described. In one example, such as in combination Figure 15 As described in 1506, 1508, and / or 1510, UE 1702 may receive one or more PDCCHs from base station 1704, which schedule DL reception 1710 from first TRP 1706, first UL transmission 1712 to first TRP 1706, and second UL transmission 1714 to second TRP 1708. As shown at 1716, UE 1702 may use different frequency bandwidths to transmit the first UL transmission 1712 and the second UL transmission 1714. In other words, UE 1702 may transmit the first UL transmission 1712 and the second UL transmission 1714 based on frequency division multiplexing (FDM).

[0158] In one example, if a UL-DL priority ordering rule is configured or defined for UL and DL transmissions in the CC, and if the DL transmission has a higher priority than the UL transmission, as shown at 1718, then UE 1702 can be configured to give higher power priority to the UL that causes less interference to DL reception (e.g., the UL further away from the DL), such as combining... Figure 16 As described in 1606. In other words, power allocation priority can be given to UL transmissions that are further away from the DL receiver in terms of frequency. For example, as shown at 1726, since the first UL transmission 1712 is closer to the DL receiver 1710 in terms of frequency than the second UL transmission 1714, UE 1702 can give the second UL transmission 1714 (e.g., to the second TRP 1708) a higher power allocation priority. In another example, as shown at 1720, UE 1702 can give the UL transmission a higher power priority based on a UL priority ordering rule (e.g., priority order 1104), and then UE 1702 can introduce or apply power backoff for UL transmissions that cause higher interference (e.g., closer to the DL receiver). For example, after applying the UL priority ordering rule (e.g., priority order 1104) to the first UL transmission 1712 and the second UL transmission 1714, UE 1702 can determine that the first UL transmission 1712 has a higher power allocation priority than the second UL transmission 1714. Therefore, UE 1702 can give higher power priority to the first UL transmit 1712. However, since the first UL transmit 1712 is closer to the DL receive 1710 in terms of frequency, the first UL transmit 1712 is more likely to cause higher interference to the DL receive 1710. Therefore, UE 1702 can apply power backoff to the first UL transmit 1712 (e.g., back off the transmit power of the first UL transmit 1712).

[0159] In another example, if a UL-DL priority ordering rule is configured or defined for UL and DL transmissions in the CC, and if one of the UL transmissions has a higher priority than the DL transmission, as shown at 1722, then UE 1702 can be configured to allocate power first to the UL transmission that has a higher priority than the DL reception. Furthermore, if a UL transmission with a lower priority is closer to the DL reception (e.g., the first UL transmission 1712), power backoff can be applied to that UL transmission. For example, if the second UL transmission 1714 has a higher priority than the DL reception 1710, and the first UL transmission 1712 has a lower priority than the DL reception 1710 (e.g., UL Tx 2 > DL Rx > UL Tx 1), then UE 1702 can provide higher power priority to the second UL transmission 1714. Additionally, since the first UL transmit 1712 has a lower priority than the second UL transmit 1714 and DL receive 1710, and the first UL transmit 1712 is also closer to the DL receive 1710 (e.g., in terms of frequency), the UE 1702 can be configured to apply power backoff to the first UL transmit 1712.

[0160] In another example, if a UL-DL priority ordering rule is configured or defined for UL and DL transmissions in the CC, and if the UL transmission has a higher priority than the DL transmission, as shown at 1724, then UE 1702 can be configured to apply the UL priority ordering rule (e.g., priority order 1104) to the UL transmissions, such as in combination with... Figure 11As described. For example, if both the first UL transmission 1712 and the second UL transmission 1714 have a higher priority than the DL reception 1710, then the UE 1702 may prioritize the power allocation of the first UL transmission 1712 and the second UL transmission 1714 based on the following priorities: (i) PRACH transmission on PCell > (ii) PUCCH or PUSCH transmission with a higher priority index > (iii) PUCCH or PUSCH transmission with the same priority index > (iv) PUCCH transmission with HARQ-ACK information and / or SR and / or LRR, or PUSCH transmission with HARQ-ACK information > (v) PUCCH transmission with CSI, or PUSCH transmission with CSI > (vi) PUSCH transmission without HARQ-ACK information or CSI, and for Type 2 random access procedures, PUSCH transmission on PCell > (vii) SRS transmission, where non-periodic SRS has a higher priority than semi-persistent and / or periodic SRS, or PRACH transmission on serving cells other than PCell, etc., where (i) may have the highest power allocation priority and (vii) may have the lowest power allocation priority.

[0161] Figure 18 Figure 1800 illustrates an example of applying a priority ordering to multiple UL transmissions in a CC based at least in part on UL-DL priorities associated with concurrent DL transmissions in the CC, according to various aspects of this disclosure. UE 1802 (e.g., UE 1502) (which may be an FD UE with multiple antenna panels) may communicate with base station 1804 (e.g., base station 1504) via a first TRP 1806 (TRP A) and a second TRP 1808 (TRP B), such as in combination with... Figure 10A , Figure 10B and Figure 15 As described. In one example, such as in combination Figure 15As described in 1506, 1508, and / or 1510, UE 1802 may receive one or more PDCCHs from base station 1804, which schedule DL reception 1810 from first TRP 1806, first UL transmission 1812 to first TRP 1806, and second UL transmission 1814 to second TRP 1808. As shown at 1816, UE 1802 may transmit the first UL transmission 1812 and the second UL transmission 1814 using the same frequency bandwidth but through different spatial beam directions. In other words, UE 1802 may transmit the first UL transmission 1812 and the second UL transmission 1814 based on spatial division multiplexing (SDM). For example, UE 1802 may transmit the first UL transmission 1812 to first TRP 1806 based on a first spatial beam direction, and UE 1802 may transmit the second UL transmission 1814 to second TRP 1808 based on a second spatial beam direction. In this example, since UE 1802 can receive DL reception 1810 from the first TRP 1806 in the same or similar direction as the first spatial beam direction (e.g., the direction used to transmit the first UL transmission 1812), the first UL transmission 1812 may cause more interference to DL reception 1810 compared to the second UL transmission 1814.

[0162] In one example, if a UL-DL priority ordering rule is configured or defined for UL and DL transmissions in the CC, and if the DL transmission has a higher priority than the UL transmission, as shown at 1818, then UE 1802 can be configured to give higher power priority to the UL, which causes less interference to DL reception, such as in combination with... Figure 16As described in 1606, in other words, power priority can be given to UL transmissions that are further away from the DL receiver in terms of spatial beam direction. For example, as shown at 1826, since the first UL transmission 1812 is closer to the DL receiver 1810 in terms of beam direction than the second UL transmission 1814, UE 1802 can give higher power allocation priority to the second UL transmission 1814 (e.g., to the second TRP 1808). In another example, as shown at 1820, UE 1802 can give higher power priority to UL transmissions based on UL priority ordering rules (e.g., priority order 1104), and then UE 1802 can introduce or apply power backoff for UL transmissions that cause higher interference (e.g., are closer to the DL receiver in terms of beam direction). For example, after applying a UL priority ordering rule (e.g., priority order 1104) to the first UL transmission 1812 and the second UL transmission 1814, the UE 1802 can determine that the first UL transmission 1812 has a higher power allocation priority than the second UL transmission 1814. Therefore, the UE 1802 can provide a higher power priority to the first UL transmission 1812. However, since the first UL transmission 1812 is closer to the DL receiver 1810 in terms of beam direction, the first UL transmission 1812 is more likely to cause higher interference to the DL receiver 1810. Therefore, the UE 1802 can apply power backoff to the first UL transmission 1812 (e.g., beam-specific power backoff, beam-specific FD power backoff, etc.) (e.g., the transmission power of the first UL transmission 1812 can be rolled back).

[0163] In another example, if a UL-DL priority ordering rule is configured or defined for UL transmissions and DL transmissions in the CC, and if one of the UL transmissions has a higher priority than the DL transmission, as shown at 1822, then UE 1802 can be configured to allocate power first to the UL transmission that has a higher priority than the DL reception. Furthermore, if a lower-priority UL transmission is closer to the DL reception in terms of beam direction (e.g., the first UL transmission 1812), power backoff (e.g., beam-specific power backoff, beam-specific FD power backoff, etc.) can be applied to that UL transmission. For example, if the second UL transmission 1814 has a higher priority than the DL reception 1810, and the first UL transmission 1812 has a lower priority than the DL reception 1810 (e.g., UL Tx 2 > DL Rx > UL Tx 1), then UE 1802 can provide higher power allocation priority to the second UL transmission 1814 (e.g., to the second TRP 1808). Additionally, since the first UL transmit 1812 has a lower priority than the second UL transmit 1814 and DL receive 1810, and the first UL transmit 1812 is also closer to the DL receive 1810 (e.g., in terms of spatial beam direction), the UE 1802 can be configured to apply power backoff to the first UL transmit 1812.

[0164] In another example, if a UL-DL priority ordering rule is configured or defined for UL and DL transmissions in the CC, and if the UL transmission has a higher priority than the DL transmission, as shown at 1824, then UE 1802 can be configured to apply the UL priority ordering rule (e.g., priority order 1104) to the UL transmissions, such as in combination with... Figure 11As described. For example, if both the first UL transmission 1812 and the second UL transmission 1814 have a higher priority than the DL reception 1810, then the UE 1802 may prioritize the power allocation of the first UL transmission 1812 and the second UL transmission 1814 based on the following priorities: (i) PRACH transmission on PCell > (ii) PUCCH or PUSCH transmission with a higher priority index > (iii) PUCCH or PUSCH transmission with the same priority index > (iv) PUCCH transmission with HARQ-ACK information and / or SR and / or LRR, or PUSCH transmission with HARQ-ACK information > (v) PUCCH transmission with CSI, or PUSCH transmission with CSI > (vi) PUSCH transmission without HARQ-ACK information or CSI, and for Type 2 random access procedures, PUSCH transmission on PCell > (vii) SRS transmission, where non-periodic SRS has a higher priority than semi-persistent and / or periodic SRS, or PRACH transmission on serving cells other than PCell, etc., where (i) may have the highest power allocation priority and (vii) may have the lowest power allocation priority.

[0165] In some scenarios, if a UE is configured to simultaneously transmit at least one UL transmission and at least one sidelink (SL) transmission (e.g., UL and SL transmissions at least partially overlap in time), then if the total UE transmission power exceeds the configured / defined maximum UE transmitter power (e.g., P_cmax), the UE can apply a power priority ordering rule to the UL and SL transmissions. In one example, if the UE can simultaneously transmit on UL and SL on two corresponding carriers of one serving cell or two corresponding serving cells, and the UL transmission overlaps with the SL transmission for a time period such that the total UE transmission power exceeds the configured / defined maximum UE transmitter power (P_cmax) during that time period, then if the SL transmission has a higher priority than the UL transmission, the UE can back down the UL transmission power before the UL transmission begins. Therefore, the total UE transmission power does not exceed P_cmax. On the other hand, if the UL transmission has a higher priority than the SL transmission, the UE can back down the SL transmission power before the SL transmission begins, ensuring that the total UE transmission power does not exceed P_cmax.

[0166] In some examples, the UE may prioritize power allocation for SL and UL transmissions / receptions based on a set of rules (hereinafter referred to as the "SL-UL power priority ranking rules"). For example, a Physical Side Link Feedback Channel (PSFCH) transmission in a time slot may have the same priority value as a Physical Side Link Shared Channel (PSSCH) reception, which has a corresponding Hybrid Automatic Repeat Request (HARQ)-Acknowledgement (ACK) message provided by the PSFCH transmission in that time slot. Similarly, a PSFCH reception in a time slot may have the same priority value as a PSSCH transmission, which has a corresponding HARQ-ACK message provided by the PSFCH reception in that time slot.

[0167] For priority ordering between SL transmissions or PSFCH / Sidelink Synchronization Signal (S-SS) / Physical Sidelink Broadcast Channel (PSBCH) block receptions and UL transmissions other than the Physical Random Access Channel (PRACH), or PUSCHs and their retransmissions scheduled by UL grants in the Random Access Response (RAR), or PUSCHs and their retransmissions corresponding to Type 2 random access procedures, or PUCCHs with sidelink HARQ-ACK information reports, if the UL transmission is used for a PUSCH or for a PUCCH with priority index 1, and if sl-PriorityThreshold-UL-URLLC is provided, then the SL transmission or reception may have a higher priority than the UL transmission if the priority value of the SL transmission is less than sl-PriorityThreshold-UL-URLLC. Otherwise, the UL transmission may have a higher priority than the SL transmission or reception. If the above conditions do not apply, the UL transmission may have a higher priority than the SL transmission or reception. In addition, or alternatively, if the priority value of SL transmission or reception is less than sl-PriorityThreshold, then SL transmission or reception may have a higher priority than UL transmission; otherwise, UL transmission may have a higher priority than SL transmission or reception.

[0168] In some examples, PRACH transmission, or PUSCH and its retransmission scheduled by UL authorization in RAR, or PUSCH and its retransmission for a type 2 random access procedure, or PUCCH with HARQ-ACK information in response to successRAR, or PUCCH indicated by DCI format 1_0 with CRC scrambled by the corresponding TC-RNTI, may have a higher priority than SL transmission or reception.

[0169] In another example, if the priority value of the PUCCH is less than the priority value of the SL transmission, then the PUCCH transmission with sidelink HARQ-ACK information reporting can have a higher priority than the SL transmission. If the priority value of the PUCCH transmission is greater than the priority value of the SL transmission, then the SL transmission can have a higher priority.

[0170] In another example, if the priority value of the PUCCH is less than the priority value of the SL reception, then the PUCCH transmission with sidelink HARQ-ACK information reporting can have a higher priority compared to the PSFCH / S-SS / PSBCH block reception. If the priority value of the PUCCH transmission is greater than the priority value of the PSFCH / S-SS / PSBCH block reception, then the SL reception has a higher priority.

[0171] In another example, when one or more SL transmissions from the UE overlap in time with multiple non-overlapping UL transmissions from the UE, the UE may perform these SL transmissions if at least one SL transmission takes precedence over all UL transmissions affected by the UE processing timeline (relative to the first SL transmission and the first UL transmission). When one or more UL transmissions from the UE overlap in time with multiple non-overlapping SL transmissions, the UE may perform UL transmissions if at least one UL transmission takes precedence over all SL transmissions affected by the UE processing timeline (relative to the first SL transmission and the first UL transmission). When an SL transmission overlaps in time with one or more overlapping UL transmissions, the UE may perform the SL transmission if the SL transmission takes precedence over all UL transmissions affected by both the UE multiplexing and processing timeline (relative to the first SL transmission and the first UL transmission), where the UE processing timeline (relative to the first SL transmission and the first UL transmission) is the same as in the case where one or more SL transmissions overlap in time with multiple non-overlapping UL transmissions. When an SL transmission overlaps in time with one or more overlapping UL transmissions, the UE may perform an SL transmission if at least one UL transmission takes precedence over the SL transmission affected by both the UE multiplexing and processing timeline (relative to the first SL transmission and the first UL transmission), wherein the UE processing timeline (relative to the first SL transmission and the first UL transmission) is the same as in the case where one or more SL transmissions overlap in time with multiple non-overlapping UL transmissions.

[0172] Figure 19Figure 1900 illustrates an example of an in-band SL / UL power priority ordering applicable to a UE in FD mode, where at least one UL transmission and at least one SL transmission are associated with power allocation priority and are transmitted simultaneously / concurrently, according to various aspects of this disclosure. A UE 1902 (e.g., a UE in FD mode or a UE with FD capability) can communicate with a base station 1904 and an SL device 1906 (e.g., a UE, RSU, vehicle UE, etc.), where the UE 1902 can concurrently transmit UL / SL transmissions and receive DL receptions. For example, the UE 1902 can be scheduled or configured to transmit an SL transmission 1908 to the SL device 1906, transmit a UL transmission 1910 to the base station 1904, and receive a DL reception 1912 from the base station 1904, wherein the transmissions in SL transmission 1908 and / or UL transmission 1910 may at least partially overlap in time with the DL reception 1912. It should be noted that the UE 1902 can also receive DL receptions from the SL device 1906.

[0173] In one example, as shown at 1914, when UL transmission and SL transmission are associated with power allocation priority, the UE can be configured to provide a higher power allocation priority to the primary cell, base station, or UL transmission. Therefore, a higher power allocation priority can be provided to UL transmission on the primary cell or BS compared to SL transmission. For example, UE 1902 can provide a higher power allocation priority to UL transmission 1910 compared to SL transmission 1908. In some examples, if P is calculated in UE 1902... CMAX and / or P CMAX,c When applying FD-specific MPR (e.g., in UE 1902 to determine P) CMAX and / or P CMAX,c If the value is considered when FD-specific MPR is taken into account, then UE 1902 can be configured to apply such a configuration (e.g., the rule shown at 1914). If P is calculated in UE 1902 CMAX and / or P CMAX,c If FD-specific MPR is not applied, then UE 1902 may not apply this configuration.

[0174] In another example, as shown at 1916, when UL transmission and SL transmission are associated with power allocation priority, the UE can provide higher power allocation priority to entities that cause less interference to DL reception (e.g., base station, serving cell, TRP, UE, sidelink device, etc.). In other words, power priority can be provided to entities such as those further away from DL reception 1912 in terms of frequency and / or spatial beam direction. For example, as shown at 1918, since the second UL transmission 1910 is closer to DL reception 1912 in terms of frequency than SL transmission 1908, UE 1902 can provide higher power allocation priority to SL transmission 1908 and can back down the transmission power of UL transmission 1910. In another example, as shown at 1920, UE 1902 can transmit SL transmission 1908 to SL device 1906 based on a first spatial beam direction, and UE 1902 can transmit UL transmission 1910 to base station 1904 based on a second spatial beam direction. In this example, if UE 1902 is scheduled to concurrently / simultaneously receive DL reception 1912 from the base station in the same or near direction as the second spatial beam direction (e.g., the direction used to transmit UL transmission 1910), then UL transmission 1910 will cause more interference to DL reception 1912 compared to SL transmission 1908. Therefore, UE 1902 can give SL transmission 1908 a higher power allocation priority (e.g., can back down the transmission power of UL transmission 1910). In other words, even if the transmission may not be on the primary cell or base station, UE 1902 can give higher power allocation priority to transmissions that cause less self-interference compared to other transmissions. In some examples, if UE 1902 calculates P... CMAX and / or P CMAX,c At that time, FD-specific MPR was not applied to the primary cell or base station (e.g., when UE 1902 determined the P of the primary cell). CMAX and / or P CMAX,c If the value is not considered when calculating P (without taking FD-specific MPR into account), then UE 1902 can be configured to apply such a configuration (e.g., the rule shown at 1916). Otherwise, if P is calculated in UE 1902... CMAX and / or P CMAX,c If UE 1902 applies an FD-specific MPR to the primary cell or base station, then UE 1902 can apply this configuration. In other words, if UE 1902 applies an FD-specific MPR to the primary cell or base station, then UE 1902 can apply the rule indicated at 1914; and if UE 1902 does not apply an FD-specific MPR to the primary cell or base station, then UE 1902 can apply the rule indicated at 1916, and so on.

[0175] In another aspect of this disclosure, when a UE simultaneously transmits at least one UL transmission and at least one SL transmission and receives at least one DL reception in a CC (e.g., UL transmission and / or SL transmission at least partially overlap with DL reception in time), if a priority ordering rule (e.g., a transmission or communication priority rule different from a power allocation priority rule) is configured for UL transmission, DL transmission, and SL transmission, the UE can determine the power allocation priority of at least one UL transmission and at least one SL transmission based at least in part on the priority associated with at least one DL transmission. For example, UL transmission and / or SL transmission can be configured to have a higher communication priority than DL reception, such that the UE can prioritize UL transmission and / or SL transmission over DL reception.

[0176] Figure 20 Figure 2000 illustrates an example of applying priority ordering to at least one UL transmission and at least one SL transmission in a CC, based at least in part on priorities associated with concurrent DL transmissions in the CC, according to various aspects of this disclosure. A UE 2002 (e.g., a UE in FD mode or a UE with FD capability) may communicate with a base station 2004 and an SL device 2006 (e.g., a UE, RSU, vehicle UE, etc.), wherein the UE 2002 may concurrently transmit UL / SL transmissions and receive DL receptions (e.g., from base station 2004 or SL device 2006 or both). For example, the UE 2002 may be scheduled or configured to transmit SL transmission 2008 to SL device 2006, transmit UL transmission 2010 to base station 2004, and receive DL reception 2012 from base station 2004, wherein the transmissions in SL transmission 2008 and / or UL transmission 2010 may at least partially overlap in time with DL reception 2012. Furthermore, as shown at 2016, UE 2002 can use different frequency bandwidths to transmit UL Transmission 2010 and SL Transmission 2008. In other words, UE 2002 can transmit UL Transmission 2010 and SL Transmission 2008 based on FDM. It should be noted that UE 2002 can also receive DL reception from SL device 2006.

[0177] In one example, if a UL-DL-SL priority ordering rule is configured or defined for UL transmissions, DL transmissions, and SL transmissions in the CC, and if DL transmissions have a higher priority than UL and DL transmissions, as shown in 2018, then UE 2002 can be configured to give higher power priority to the UL or SL that causes less interference to DL reception (e.g., UL / SL further away from DL), such as in combination with... Figure 19As described in 1916. In other words, power priority can be given to UL transmissions or SL transmissions that are further away from DL reception in terms of frequency. For example, as shown at 2026, since UL transmission 2010 is closer to DL reception 2012 in terms of frequency than SL transmission 2008, UE 2002 can give SL transmission 2008 (e.g., to SL device 2006) a higher power allocation priority. In another example, as shown at 2020, UE 2002 can give higher power priority to UL transmissions or SL transmissions based on SL-UL power priority ranking rules, and then UE 2002 can introduce or apply power backoff for UL transmissions or SL transmissions that cause more interference to DL reception (e.g., are closer to DL reception). For example, after applying SL-UL power priority ranking rules to UL transmission 2010 and SL transmission 2008, UE 2002 can determine that UL transmission 2010 has a higher power allocation priority than SL transmission 2008. Therefore, UE 2002 can give higher power priority to UL Transmit 2010. However, since UL Transmit 2010 is closer to DL Receive 2012 in terms of frequency, UL Transmit 2010 is more likely to cause greater interference to DL Receive 2012. Therefore, UE 2002 can apply power backoff to UL Transmit 2010 (e.g., back off the transmit power of UL Transmit 2010).

[0178] In another example, if a UL-DL-SL priority ordering rule is configured or defined for UL transmissions, DL transmissions, and SL transmissions in the CC, and if one of the UL transmissions or SL transmissions has a higher priority than the DL transmission, as shown in 2022, then UE 2002 can be configured to allocate power first to the UL transmission or SL transmission that has a higher priority than the DL reception. Furthermore, if a lower-priority UL transmission or SL transmission is closer to the DL reception (e.g., UL transmission 2010), power backoff can be applied to that UL transmission or SL transmission. For example, if SL transmission 2008 has a higher priority than DL reception 2012, and UL transmission 2010 has a lower priority than DL reception 2012 (e.g., SL Tx > DL Rx > UL Tx), then UE 2002 can provide higher power priority to SL transmission 2008. Additionally, since UL Transmit 2010 has a lower priority than SL Transmit 2008 and DL Receive 2012, and UL Transmit 2010 is also closer to DL Receive 2012 (e.g., in terms of frequency), UE 2002 can be configured to apply power backoff to UL Transmit 2010.

[0179] In another example, if a UL-DL-SL priority ordering rule is configured or defined for UL transmission, DL transmission, and SL transmission in CC, and if both UL transmission and SL transmission have a higher priority than DL transmission, as shown in 2024, then UE 2002 can be configured to apply the SL-UL power priority ordering rule to UL transmission and SL transmission.

[0180] Figure 21 Figure 2100 illustrates an example of applying priority ordering to at least one UL transmission and at least one SL transmission in a CC, based at least in part on priorities associated with concurrent DL transmissions in the CC, according to various aspects of this disclosure. A UE 2102 (e.g., a UE in FD mode or a UE with FD capability) can communicate with a base station 2104 and an SL device 2106 (e.g., a UE, RSU, vehicle UE, etc.), wherein the UE 2102 can concurrently transmit UL / SL transmissions and receive DL receptions. For example, the UE 2102 can be scheduled or configured to transmit an SL transmission 2108 to the SL device 2106, transmit a UL transmission 2110 to the base station 2104, and receive a DL reception 2112 from the base station 2104, wherein the transmissions in SL transmission 2108 and / or UL transmission 2110 may at least partially overlap in time with the DL reception 2112. Furthermore, as shown at 2116, UE 2102 can transmit UL transmission 2110 and SL transmission 2108 using the same frequency bandwidth but through different spatial beam directions. In other words, UE 2102 can transmit UL transmission 2110 and SL transmission 2108 based on SDM. For example, UE 2102 can transmit UL transmission 2110 to base station 2104 based on a first spatial beam direction, and UE 2102 can transmit SL transmission 2108 to SL device 2106 based on a second spatial beam direction. In this example, since UE 2102 can receive DL reception 2112 from base station 2104 in the same or similar direction as the first spatial beam direction (e.g., the direction used to transmit UL transmission 2110), UL transmission 2110 will cause more interference to DL reception 2112 compared to SL transmission 2108. It should be noted that UE 2002 can also receive DL reception from SL device 2006.

[0181] In one example, if a UL-DL-SL priority ordering rule is configured or defined for UL transmissions, DL transmissions, and SL transmissions in the CC, and if DL transmissions have a higher priority than UL and DL transmissions, as shown at 2118, then UE 2102 can be configured to give higher power priority to the UL or SL that causes less interference to DL reception (e.g., UL / SL further away from DL), such as combining... Figure 19As described in 1916. In other words, power priority can be given to UL transmissions or SL transmissions that are further away from DL reception in terms of spatial beam direction. For example, as shown at 2126, since UL transmission 2110 is closer to DL reception 2112 in terms of spatial beam direction than SL transmission 2108, UE 2102 can give higher power allocation priority to SL transmission 2108 (e.g., to SL device 2106). In another example, as shown at 2120, UE 2102 can give higher power priority to UL transmissions or SL transmissions based on SL-UL power priority ranking rules, and then UE 2102 can introduce or apply power backoff for UL transmissions or SL transmissions that cause more interference to DL reception (e.g., are closer to DL reception). For example, after applying SL-UL power priority ranking rules to UL transmission 2110 and SL transmission 2108, UE 2102 can determine that UL transmission 2110 has a higher power allocation priority than SL transmission 2108. Therefore, UE2102 can provide higher power priority to UL transmit 2110. However, since UL transmit 2110 is closer to DL receive 2112 in terms of beam direction, UL transmit 2110 is more likely to cause higher interference to DL receive 2112. Therefore, UE22 can apply power backoff to UL transmit 2110 (e.g., back off the transmit power of UL transmit 2110).

[0182] In another example, if a UL-DL-SL priority ordering rule is configured or defined for UL transmission, DL transmission, and SL transmission in the CC, and if one of the UL transmissions or SL transmissions has a higher priority than the DL transmission, as shown at 2122, then UE 2102 can be configured to allocate power first to the UL transmission or SL transmission, which has a higher priority than the DL reception. Furthermore, if a lower-priority UL transmission or SL transmission is closer to the DL reception in terms of spatial beam direction (e.g., UL transmission 2110), power backoff can be applied to that UL transmission or SL transmission. For example, if SL transmission 2108 has a higher priority than the DL reception 2112, and UL transmission 2110 has a lower priority than the DL reception 2112 (e.g., SL Tx > DL Rx > UL Tx), then UE 2102 can provide higher power priority to SL transmission 2108. Additionally, since UL transmit 2110 has a lower priority than SL transmit 2108 and DL receive 2112, and UL transmit 2110 is also closer to DL receive 2112 (e.g., in terms of frequency), UE 2102 can be configured to apply power backoff to UL transmit 2110.

[0183] In another example, if a UL-DL-SL priority ordering rule is configured or defined for UL transmission, DL transmission, and SL transmission in the CC, and if both UL transmission and SL transmission have a higher priority than DL transmission, as shown at 2124, then UE 2102 can be configured to apply the SL-UL power priority ordering rule to UL transmission and SL transmission.

[0184] Figure 22 This is a flowchart 2200 of a wireless communication method. The method can be performed by a UE or a component of a UE (e.g., UE 104, UE 350, UE 1302, UE 1502, UE 1702, UE 1802, UE 1902, UE 2002, UE 2102; device 2402; processing system, which may include memory 360 and may be the entire UE 350 or components of UE 350 (such as TX processor 368, RX processor 356, and / or controller / processor 359)). The method enables the UE to apply power backoff and / or power allocation priority ordering to at least one of the multiple transmissions when at least one DL reception at least partially overlaps with multiple transmissions in time.

[0185] At 2202, the UE can determine FD-specific power backoff, which is associated with each of at least one of a plurality of transmissions in a time slot configured as an FD time slot. Each FD-specific power backoff can be based on whether the corresponding transmission will cause self-interference with DL reception in that FD time slot. The plurality of transmissions may overlap in time, such as in combination. Figures 15 to 21 As described. For example, in Figure 15 At positions 1512 and 1513, UE 1502 can determine P based on available information about the scheduled UL transmission and based on FD-specific MPR. CMAX,c and P CMAX The UL transmission may overlap with the DL reception in time, as shown at 1526. The determination of this FD-specific power backoff can, for example, be determined by... Figure 24 The FD-specific power backoff determination component 2440 of the device 2402 performs this action. The FD-specific power backoff can be one of the following: MPR, cell-specific MPR, intra-cell frequency-specific power backoff, or intra-cell beam-specific power backoff. The multiple transmissions can include multiple UL transmissions, multiple SL transmissions, or at least one UL transmission and at least one SL transmission. For example, the multiple UL transmissions can be for multiple TRPs.

[0186] In one example, the first transmission causes more self-interference to the DL receiver, while the second transmission causes less self-interference. The first transmission may have a larger FD-specific power backoff compared to the second transmission, such as when combined with... Figures 16 to 21 As described.

[0187] In another example, the FD-specific power backoff can be an MPR. This MPR can be a cell-specific MPR, and the cell-specific MPR can be based on at least one of the following: the LCRB used for transmission in the cell; or the lowest RB index of the RBs transmitted in the cell, such as combining... Figure 12 As described. In such an example, when the UE determines power backoff, the UE may determine the cell-specific MPR of each carrier in a set of carriers, and when the UE determines the transmit power, the UE may determine the transmit power of each of at least one transmit based on the determined cell-specific MPR corresponding to the cell used for transmission.

[0188] In another example, such as combination Figure 15 As described, when a DL reception scheduled for a UE at least partially overlaps in time with at least one transmission, power backoff may be applied to at least one transmission in the FD time slot. Alternatively, power backoff may be applied to at least one transmission in the FD time slot, regardless of whether a DL reception scheduled for a UE at least partially overlaps in time with at least one transmission.

[0189] In another example, each FD-specific power backoff can be further determined based on whether the corresponding transmission has a higher priority than the DL reception in the FD slot, such as combining... Figure 17 , Figure 18 , Figure 20 and Figure 21 As described.

[0190] At 2204, the UE can determine the transmission power of each transmission in at least one transmission in the FD time slot based on the determined FD-specific power backoff for each transmission in at least one transmission, such as combining... Figures 15 to 21 As described. For example, at 1513, UE 1502 can determine the transmission power of each of these UL transmissions. This transmission power can be determined, for example, by... Figure 24 The transmission power determination component 2442 of the device 2402 in the middle performs the operation.

[0191] In one example, determining the transmission power of each transmission in at least one transmission within an FD time slot may include: determining the cell-specific maximum output power limit P for that transmission. CMAX _ H,C Based on the determined FD-specific backoff, determine the cell-specific maximum output power lower limit P for this transmission. CMAX _ L,C Based on the determined cell-specific maximum output power lower limit P transmitted. CMAX _ L,Cand the determined maximum output power limit P for the specific cell CMAX _ H,C Determine the cell-specific maximum output power P of the transmitted signal. CMAX,C , where P CMAX _ L,C ≤P CMAX,C ≤P CMAX _ H,C The cell-specific maximum output power P of the transmission can be determined based on at least one of the following: whether the corresponding transmission will cause self-interference to DL reception in the FD time slot, self-interference cancellation capability, or self-interference threshold specification. CMAX,C Within range P CMAX _ L,C ≤P CMAX,C ≤P CMAX _ H,C Internally, such as combining Figure 15 As described in 1512 and 1513.

[0192] At 2206, the UE can determine the initial priority of each transmission in at least one transmission, such as combining Figure 11 As described. For example, the UE may determine the initial priority of multiple transmissions based on priority order 1104. This initial priority may be determined, for example, by... Figure 24 The priority determination component 2444 of the device 2402 in the middle performs the operation.

[0193] At 2208, when each of the at least one transmissions has the same initial priority and the total transmission power exceeds a threshold power, the UE may prioritize each of the at least one transmissions to determine the final priority of each of the at least one transmissions, wherein the transmission power may be based on the determined final priority, such as by combining... Figures 15 to 21 As described. For example, in Figure 16 At locations 1602 and 1606, when the first UL transmission 1507 and the second UL transmission 1509 have the same priority order, the UE 1202 may apply a priority ordering rule to the first UL transmission 1507 and the second UL transmission 1509. The priority ordering of this at least one transmission may, for example, be determined by… Figure 24 The priority sorting of device 2402 is performed by application component 2446.

[0194] In one example, the primary cell in the first transmission of multiple transmissions may take precedence over the secondary cell in the second transmission of multiple transmissions, such as in combination. Figure 16 and Figure 19 As described.

[0195] In another example, a first cell in a first transmission of multiple transmissions may take precedence over a second cell in a second transmission of multiple transmissions, provided that the second transmission satisfies at least one of the following: causes more interference to DL reception in the FD time slot compared to the first transmission; is closer in spatial beam direction to the spatial beam direction of the DL reception in the FD time slot; or is closer in frequency to the frequency of the DL reception in the FD time slot, such as in combination. Figure 16 and Figure 19 As described.

[0196] At 2210, the UE can transmit one or more of at least one transmission based on the determined transmission power of the corresponding transmission, such as combining... Figures 15 to 21 As described. For example, at 1516 and 1518, UE 1502 may transmit a first UL transmission 1507 and a second UL transmission 1509 based on a power allocation priority sorting rule (e.g., priority order 1104), and if multiple transmissions have the same priority, UE 1502 may also apply a combination Figures 16 to 21 The additional priority ordering described. The transmission of the first UL transmission 1507 and the second UL transmission 1509 based on the power allocation periodization rule can be, for example... Figure 24 The transmission power configuration component 2448 and / or transmission component 2434 of the device 2402 are used to perform this.

[0197] Figure 23 This is a flowchart 2300 of a wireless communication method. The method can be performed by a UE or a component of a UE (e.g., UE 104, UE 350, UE 1302, UE 1502, UE 1702, UE 1802, UE 1902, UE 2002, UE 2102; device 2402; processing system, which may include memory 360 and may be the entire UE 350 or components of UE 350 (such as TX processor 368, RX processor 356, and / or controller / processor 359)).

[0210] Figure 24Figure 2400 illustrates an example of a hardware implementation for device 2402. Device 2402 may be a UE, a component of a UE, or implement UE functionality. In some aspects, device 2402 may include a cellular baseband processor 2404 (also referred to as a modem) coupled to a cellular RF transceiver 2422.

This computer-readable media / memory may be non-transitory. Cellular baseband processor 2404 is responsible for general processing, including executing software stored on a computer-readable medium / memory.

The computer-readable medium / memory can also be used to store data manipulated by cellular baseband processor 2404 during software execution. Cellular baseband processor 2404 also includes a receiving component 2430, a communication manager 2432, and a transmitting component 2434. Communication manager 2432 includes one or more of the illustrated components.

[0212] The device may include execution Figure 22 and Figure 23 The flowchart shows the algorithm's additional components in each box of the algorithm's boxes. Therefore, Figure 22 and Figure 23 Each box in the flowchart can be executed by a component, and the apparatus can include one or more of those components. These components can be one or more hardware components specifically configured to execute the process / algorithm, implemented by a processor configured to execute the process / algorithm, stored in a computer-readable medium for implementation by a processor, or some combination thereof.

[0213] As shown in the figure, device 2402 may include various components configured for various functions. In one configuration, device 2402, specifically cellular baseband processor 2404, includes components for determining FD-specific power backoff associated with each of at least one of a plurality of transmissions in a time slot configured as an FD time slot, each FD-specific power backoff based on whether the corresponding transmission would cause self-interference with DL reception in that FD time slot, the plurality of transmissions overlapping in time (e.g., FD power backoff determination component 2440). Device 2402 includes components for determining the transmission power of each of the at least one transmissions in the FD time slot based on the determined FD-specific power backoff of each of the at least one transmissions (e.g., transmission power determination component 2442). Device 2402 includes components for determining an initial priority for each of the at least one transmissions (e.g., priority determination component 2444). Apparatus 2402 includes components for prioritizing each of the at least one transmissions when each of the at least one transmissions has the same initial priority and the total transmission power exceeds a threshold power, to determine the final priority of each of the at least one transmissions, wherein the transmission power is based on the determined final priority (e.g., priority prioritization application component 2446). Apparatus 2402 includes components for transmitting one or more of the at least one transmissions based on the determined transmission power of the corresponding transmission (e.g., transmission power configuration component 2448 and / or transmission component 2434). The FD-specific power backoff can be one of the following: MPR, cell-specific MPR, intra-cell frequency-specific power backoff, or intra-cell beam-specific power backoff. The multiple transmissions can include multiple UL transmissions, multiple SL transmissions, or at least one UL transmission and at least one SL transmission. The multiple UL transmissions can be for multiple TRPs.
