Power control for physical sidelink feedback channel

Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) can receive configuration information indicating a per-resource block power offset between one or more first resource blocks for carrying acknowledgement / negative-acknowledgement feedback and one or more second resource blocks in a common interlace. The UE can transmit a physical sidelink feedback channel transmission in the one or more first resource blocks and the one or more second resource blocks using the power offset and using a transmit power that depends on whether a downlink path loss value is indicated in the configuration information. Numerous other aspects are described.

[0002] This patent application claims priority to U.S. Provisional Patent Application No. 63 / 595,528, filed November 2, 2023, entitled “POWER CONTROL FOR APHYSICAL SIDELINK FEEDBACK CHANNEL,” and U.S. Non-Provisional Patent Application No. 18 / 888,848, filed September 18, 2023, entitled “POWER CONTROL FOR APHYSICAL SIDELINK FEEDBACK CHANNEL,” which are hereby expressly incorporated herein by reference. Technical Field

[0003] All aspects of this disclosure relate to wireless communication in general, and more particularly to techniques, apparatus and methods for power control of the Physical Side Link Feedback Channel (PSFCH). Background Technology

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

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

[0006] Some aspects described herein relate to an apparatus for wireless communication at a user equipment (UE). The apparatus may include one or more memories and one or more processors coupled to the one or more memories. The one or more processors may be configured to cause the UE to receive configuration information indicating a power offset for each resource block between one or more first resource blocks used to carry acknowledgment (ACK) / negative acknowledgment (NACK) feedback and one or more second resource blocks in a common interleaving. The one or more processors may be configured to cause the UE to use this power offset and transmit a Physical Side Link Feedback Channel (PSFCH) in the one or more first resource blocks and the one or more second resource blocks using a transmit power depending on whether a downlink path loss value is indicated in the configuration information.

[0007] Some aspects described herein relate to an apparatus for wireless communication at a network node. The apparatus may include one or more memories and one or more processors coupled to the one or more memories. The one or more processors may be configured to cause the network node to generate configuration information for PSFCH, the configuration information indicating a power offset per resource block between one or more first resource blocks used to carry ACK / NACK feedback and one or more second resource blocks in a common interleaving. The one or more processors may be configured to cause the network node to transmit the configuration information.

[0008] Some aspects described herein relate to a method of wireless communication performed by a device of a UE. The method may include receiving configuration information indicating a power offset for each resource block between one or more first resource blocks used to carry ACK / NACK feedback and one or more second resource blocks in common interleaving.

[0011] Some aspects described herein relate to a non-transitory computer-readable medium storing a set of instructions for wireless communication by a network node. When executed by one or more processors of the network node, the set of instructions causes the network node to generate configuration information for a PSFCH (Power over Connection Function), indicating a power offset for each resource block between one or more first resource blocks used to carry ACK / NACK feedback and one or more second resource blocks in a common interleaving. When executed by one or more processors of the network node, the set of instructions causes the network node to transmit the configuration information.

[0012] Some aspects described herein relate to an apparatus for wireless communication.

[0028] Various aspects of this disclosure are described below with reference to the accompanying drawings. However, aspects of this disclosure may be embodied in many different forms and should not be construed as limited to any specific aspect illustrated or described with reference to the drawings or otherwise presented in this disclosure. Rather, these aspects are provided so that this disclosure will be comprehensive and complete, and will fully convey the scope of protection of this disclosure to those skilled in the art. Those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, various combinations or numbers of aspects set forth herein may be used to implement an apparatus or a practice. Furthermore, the scope of this disclosure is intended to cover apparatuses having structures and / or functionalities other than those available for practicing the various aspects of this disclosure set forth herein, or methods practiced using these other structures and / or functionalities. Any aspect of this disclosure disclosed herein may be embodied by one or more elements of the claims.

[0029] Various methods, operations, apparatuses, and techniques will now be presented with reference to them. These methods, operations, apparatuses, and techniques will be described in detail below and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, or algorithms (collectively, “elements”). These elements may be implemented using hardware, software, or a combination of hardware and software. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.

[0030] User equipment (UE) can send Hybrid Automatic Repeat Request (HARQ) feedback to indicate whether the UE has received communication from another device. HARQ feedback may include an acknowledgment (ACK) indicating that the UE has successfully received communication from the other device, or a negative acknowledgment (NACK) indicating that the UE has not successfully received communication from the other device. In sidelink communication, the other device can be another UE, and HARQ feedback can be sent by the UE to the other UE via the Physical Sidelink Feedback Channel (PSFCH).

[0031] Interleaving is the basic unit of resource allocation (such as air interface resource allocation), characterized by any combination of frequency spans (e.g., which can be divided into subbands and / or subcarriers), time spans (e.g., which can be divided into subtime spans, such as slots and / or symbols), and / or one or more physical resource blocks (PRBs). Interleaving can be, for example, common interleaving or dedicated interleaving. In some examples, the resources of a common interleaving may be accessible to any UE and / or shared by multiple UEs, while the resources of a dedicated interleaving may only be accessible to a single UE at a given time. In some examples, each PSFCH transmission may occupy a single common interleaving and a certain number (labeled K3) of dedicated PRBs. The number of dedicated PRBs can be, for example, one PRB, two PRBs, five PRBs, etc.

[0032] In common interleaving, PSFCH transmission may include a dummy signal, and in a dedicated PRB, PSFCH transmission may indicate ACK / NACK feedback. Since the number of dedicated PRBs used for PSFCH transmission can be multiple, power control methods designed for PSFCH transmission occupying only one RB may result in inefficient transmission power usage. Furthermore, the transmission power used in common interleaving carrying a dummy signal may be less than the transmission power used in a dedicated PRB carrying ACK / NACK feedback. However, the UE may not be able to determine how to efficiently allocate transmission power between common interleaving PRBs and dedicated PRBs. Therefore, the UE may use excessive power for PSFCH transmission in common interleaving PRBs, thus excessively depleting the UE's battery. Additionally, the UE may use insufficient power for PSFCH transmission in PRBs carrying ACK / NACK feedback, which may degrade the performance of ACK / NACK feedback arriving at the receiving device and / or lead to retransmissions of ACK / NACK feedback that consume additional computing and / or network resources.

[0033] The various aspects involve sidelink communication and power control for the PSFCH as a whole. Some aspects are more specifically related to power control for PSFCH waveforms using common interleaving in unlicensed spectrum. In some aspects, the per-resource block (RB) power offset of the PSFCH can be signaled to the UE by the network node. The per-RB power offset can occur between the RB carrying ACK / NACK feedback and the RBs in the common interleaving. Therefore, the per-RB power offset can be used to indicate the per-RB transmit power for the RBs carrying ACK / NACK feedback and the RBs in the common interleaving for the PSFCH transmission.

[0034] Specific aspects of the subject matter described in this disclosure can be implemented to achieve one or more of the following potential advantages. In some examples, by signaling the power offset per RB to the UE, the described techniques can be used to enable the UE to efficiently allocate transmit power to PSFCH transmission between the RB carrying ACK / NACK feedback and the RB in the common interleaving, thereby saving power and improving the performance of the ACK / NACK feedback upon arrival at the receiving device. In addition to indicating the power offset between the RB carrying ACK / NACK feedback and the RB in the common interleaving, the power offset parameter in the signaling can also be used to indicate the absence of a power offset, thereby reducing the signaling overhead associated with the use of individual parameters.

[0035] Multiple access radio access technology (RAT) has been adopted in various telecommunications standards to provide a common protocol that enables different wireless communication devices to communicate at the city, enterprise, national, regional, or global levels. For example, 5G New Radio (NR) is part of the ongoing evolution of mobile broadband, promulgated by the 3rd Generation Partnership Project (3GPP). 5G NR supports a variety of technologies and use cases, including enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), massive machine-type communication (mMTC), millimeter wave (mmWave) technology, beamforming, network slicing, edge computing, Internet of Things (IoT) connectivity and management, and network function virtualization (NFV).

[0036] As the demand for broadband access increases and as the technologies supported by wireless communication networks evolve, further technological improvements can be adopted or implemented in 5G NR or future RATs (such as 6G) to further drive the evolution of wireless communication for a wide range of existing and new use cases and applications. Such technological improvements can be associated with: new frequency band expansion, licensed and unlicensed spectrum access, overlapping spectrum use, small cell deployments, non-terrestrial network (NTN) deployments, distributed network architectures and network topology expansions, device aggregation, advanced duplex communication, sidelinks and other device-to-device direct communication, IoT (including passive or ambient IoT) networks, reduced-capacity (RedCap) UE functionality, industrial connectivity, multi-subscriber implementations, high-precision positioning, radio frequency (RF) sensing and / or artificial intelligence or machine learning (AI / ML), and more. These technological improvements can support use cases such as: wireless backhaul, wireless data centers, extended reality (XR) and metaverse applications, meta-services for supporting vehicle connectivity, holographic and mixed reality communications, autonomous and collaborative robots, vehicle platooning and cooperative maneuvering, sensor networks, gesture monitoring, brain-computer interfaces, digital twin applications, asset management, and comprehensive coverage applications using off-ground and / or aerial platforms, etc. The methods, operations, apparatuses, and techniques described herein can implement one or more of the foregoing technologies and / or support one or more of the foregoing use cases.

[0037] Figure 1 This is a diagram illustrating an example of a wireless communication network 100 according to the present disclosure. The wireless communication network 100 may be a 5G (or NR) network or a 6G network, or may include elements of a 5G (or NR) network or a 6G network, etc. The wireless communication network 100 may include a plurality of network nodes 110, shown as network node (NN) 110a, network node 110b, network node 110c, and network node 110d. Network nodes 110 may support communication with a plurality of UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e).

[0038] Network nodes 110 and UEs 120 of wireless communication network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, frequency bands, carriers, and / or channels according to frequency or wavelength. For example, devices of wireless communication network 100 can communicate using one or more operating frequency bands. In some aspects, multiple wireless networks 100 can be deployed in a given geographical area. Each wireless communication network 100 can support a specific RAT (which may also be referred to as an air interface) and can operate on one or more carrier frequencies in one or more frequency ranges. Examples of RATs include 4G RATs, 5G / NRRATs, and / or 6G RATs, etc. In some examples, when multiple RATs are deployed in a given geographical area, each RAT in that geographical area can operate on a different frequency to avoid interference with each other.

[0039] Various operating frequency bands have been defined as frequency ranges designated FR1 (410 MHz to 7.125 GHz), FR2 (24.25 GHz to 52.6 GHz), FR3 (7.125 GHz to 24.25 GHz), FR4a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Although a portion of FR1 is greater than 6 GHz, in some documents and articles, FR1 is often (interchangeably) referred to as the “sub-6 GHz” band. Similarly, in some documents and articles, FR2 is often (interchangeably) referred to as the “millimeter wave” band, but this is different from the Very High Frequency (EHF) band (30 GHz to 300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU). The frequencies between FR1 and FR2 are often referred to as the mid-band frequencies, including FR3. Frequency bands falling within FR3 can inherit FR1 or FR2 characteristics, thereby effectively extending the characteristics of FR1 or FR2 into mid-band frequencies. Therefore, "below 6 GHz" (if used herein) can broadly refer to frequencies less than 6 GHz, within FR1, and / or included in mid-band frequencies. Similarly, the term "millimeter wave" (if used herein) can broadly refer to frequencies included in mid-band frequencies, within FR2, FR4, FR4-a, FR4-1, or FR5, and / or within the EHF band. Higher frequency bands can extend 5G NR operation, 6G operation, and / or other RATs above 52.6 GHz. For example, each of FR4a, FR4-1, FR4, and FR5 falls within the EHF band. In some examples, the wireless communication network 100 can implement dynamic spectrum sharing (DSS), where multiple RATs (e.g., 4G / LTE and 5G / NR) are implemented within a single frequency band using dynamic bandwidth allocation (e.g., based on user demand). It is conceivable that the frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1 and / or FR5) can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0040] Network node 110 may include one or more devices, components, or systems that enable communication between UE 120 and one or more devices, components, or systems of wireless communication network 100. Network node 110 may be, may include, or may be referred to as an NR network node, 5G network node, 6G network node, node B, eNB, gNB, access point (AP), transmit / receive point (TRP), mobility element, core, network entity, network element, network equipment, and / or another type of device, component, or system included in a radio access network (RAN).

[0041] Network node 110 may be implemented as a single physical node (e.g., a single physical structure) or as two or more physical nodes (e.g., two or more different physical structures). For example, network node 110 may be a device or system implementing a portion of a radio protocol stack, a device or system implementing a complete radio protocol stack (such as a complete gNB protocol stack), or a collection of devices or systems collectively implementing a complete radio protocol stack. For example, as shown, network node 110 may be an aggregated network node (with an aggregated architecture), meaning that network node 110 can implement a complete radio protocol stack physically and logically integrated within a single node (e.g., a single physical structure) in the wireless communication network 100. For example, aggregated network node 110 may consist of a single standalone base station or a single TRP that uses the complete radio protocol stack to implement or facilitate communication between UE 120 and the core network of wireless communication network 100.

[0042] Alternatively, and also as shown in the figure, network node 110 can be a distributed network node (sometimes referred to as a distributed base station), meaning that network node 110 can implement a radio protocol stack that is physically and / or logically distributed across two or more nodes in the same geographical location or in different geographical locations. For example, distributed network nodes can have a distributed architecture. In some deployments, distributed network node 110 base stations can be used in integrated access and backhaul (IAB) networks, in open radio access networks (O-RAN) (such as network configurations compliant with the O-RAN Alliance), or in virtualized radio access networks (vRAN) (also referred to as cloud radio access networks (C-RAN)) to facilitate scaling by separating base station functionality into multiple units that can be deployed individually.

[0043] Network nodes 110 of the wireless communication network 100 may include one or more central units (CUs), one or more distributed units (DUs), and / or one or more radio units (RUs). CUs may host one or more higher-layer control functions, such as Radio Resource Control (RRC) functions, Packet Data Convergence Protocol (PDCP) functions, and / or Service Data Adaptation Protocol (SDAP) functions, etc. DUs may host one or more of the Radio Link Control (RLC) layer, Media Access Control (MAC) layer, and / or one or more higher physical (PHY) layers, depending at least in part on a functional split (such as functional splits defined by 3GPP). In some examples, DUs may also host one or more lower PHY layer functions, such as Fast Fourier Transform (FFT), Inverse FFT (iFFT), beamforming, Physical Random Access Channel (PRACH) extraction and filtering, and / or scheduling of resources for one or more UEs 120, etc. RUs may host RF processing functions or lower PHY layer functions, such as FFT, iFFT, beamforming, or PRACH extraction and filtering, etc., depending on a functional split (such as lower-layer functional splits). In this type of architecture, each RU can be operated to handle over-the-air (OTA) communications with one or more UE 120s.

[0044] In some aspects, a single network node 110 may include a combination of one or more CUs, one or more DUs, and / or one or more RUs. Additionally or alternatively, network node 110 may include one or more near real-time (near RT) RAN Intelligent Controllers (RICs) and / or one or more non-real-time (non-RT) RICs. In some examples, CUs, DUs, and / or RUs may be implemented as virtual units, such as Virtual Central Units (VCUs), Virtual Distributed Units (VDUs), or Virtual Radio Units (VRUs), etc. Virtual units may be implemented as virtual network functions, such as those associated with cloud deployments.

[0045] Some network nodes 110 (e.g., base stations, RUs, or TRPs) can provide communication coverage for specific geographic areas. In 3GPP, the term "cell" can refer to the coverage area of ​​network node 110 or to network node 110 itself, depending on the context in which the term is used. Network node 110 can support one or more (e.g., three) cells. In some examples, network node 110 can provide communication coverage for macro cells, pico cells, femto cells, or another type of cell. A macro cell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UE 120 with a service subscription. A pico cell can cover a relatively small geographic area and can allow unrestricted access by UE 120 with a service subscription. A femto cell can cover a relatively small geographic area (e.g., a residential area) and can allow restricted access by UE 120 associated with that femto cell (e.g., UE 120 in a Closed Subscriber Group (CSG)). The network node 110 used for a macro cell may be referred to as a macro network node. Network node 110 used for a pico cell may be referred to as a pico network node. Network node 110 used for a femtocell may be referred to as a femto network node or a home network node. In some examples, the cell may not necessarily be stationary. For example, the geographical area of ​​the cell may be mobile based on the location of the associated mobile network node 110 (e.g., a train, satellite base station, unmanned aerial vehicle, or non-terrestrial network (NTN) network node).

[0046] The wireless communication network 100 can be a heterogeneous network, comprising different types of network nodes 110, such as macro network nodes, piconet nodes, femtonet nodes, relay network nodes, aggregation network nodes, and / or decomposition network nodes, etc. Figure 1 In the example shown, network node 110a can be a macro network node for macro cell 130a, network node 110b can be a pico network node for pico cell 130b, and network node 110c can be a femto network node for femto cell 130c. Compared to other types of network nodes 110, the various types of network nodes 110 can typically transmit at different power levels, serve different coverage areas, and / or have different effects on interference in the wireless communication network 100. For example, macro network nodes can have high transmit power levels (e.g., 5 watts to 40 watts), while pico network nodes, femto network nodes, and relay network nodes can have lower transmit power levels (e.g., 0.1 watts to 2 watts).

[0047] In some examples, network node 110 may be, may include, or operate as a RU, TRP, or base station communicating with one or more UEs 120 via a radio access link (which may be referred to as a "Uu" link). The radio access link may include a downlink and an uplink. A "downlink" (or "DL") refers to the communication direction from network node 110 to UE 120, and an "uplink" (or "UL") refers to the communication direction from UE 120 to network node 110. Downlink channels may include one or more control channels and one or more data channels. Downlink control channels may be used to transmit downlink control information (DCI) (e.g., scheduling information, reference signals, and / or configuration information) from network node 110 to UE 120. Downlink data channels may be used to transmit downlink data (e.g., user data associated with UE 120) from network node 110 to UE 120. Downlink control channels may include one or more physical downlink control channels (PDCCH), and downlink data channels may include one or more physical downlink shared channels (PDSCH). The uplink channel may similarly include one or more control channels and one or more data channels. The uplink control channel can be used to transmit uplink control information (UCI) (e.g., reference signals and / or feedback corresponding to one or more downlink transmissions) from UE 120 to network node 110. The uplink data channel can be used to transmit uplink data (e.g., user data associated with UE 120) from UE 120 to network node 110. The uplink control channel may include one or more physical uplink control channels (PUCCH), and the uplink data channel may include one or more physical uplink shared channels (PUSCH). The downlink and uplink may each include a set of resources on which network node 110 and UE 120 can communicate.

[0048] Downlink and uplink resources may include time-domain resources (frames, subframes, time slots, and / or symbols), frequency-domain resources (bands, component carriers, subcarriers, resource blocks, and / or resource elements), and / or spatial-domain resources (specific transmission directions and / or beam parameters). Frequency-domain resources in some bands may be subdivided into bandwidth portions (BWPs). A BWP may be a contiguous block of frequency-domain resources allocated to one or more UEs 120 (e.g., a contiguous block of resource blocks). A UE 120 may be configured with both an uplink BWP and a downlink BWP (where the uplink BWP and downlink BWP may be the same BWP or different BWPs). BWPs may be dynamically configured and / or reconfigured (e.g., by sending DCI configuration to one or more UEs 120 via network node 110), meaning that BWPs may be adjusted in real-time (or near real-time) based on changing network conditions in the wireless communication network 100 and / or based on the specific requirements of one or more UEs 120. This allows for more efficient use of available frequency domain resources in the wireless communication network 100, as fewer frequency domain resources can be allocated to the BWP for UE 120 (which reduces the number of frequency domain resources that UE 120 needs to monitor), thus allowing more frequency domain resources to be distributed across multiple UE 120s. Therefore, the BWP can also assist in the implementation of such UE 120s by facilitating the configuration of smaller bandwidths for communications performed by lower-capacity UE 120s.

[0049] As described above, in some aspects, the wireless communication network 100 may be an IAB network, may include an IAB network, or may be included in an IAB network. In an IAB network, at least one network node 110 is an anchor network node communicating with a core network. The anchor network node 110 may also be referred to as an IAB donor (or "IAB donor"). The anchor network node 110 may be connected to the core network via a wired backhaul link. For example, the Ng interface of the anchor network node 110 may be terminated at the core network. Additionally or alternatively, the anchor network node 110 may be connected to one or more devices in the core network that provide core access and mobility management functions (AMF). An IAB network typically also includes multiple non-anchor network nodes 110, which may also be referred to as relay network nodes or simply IAB nodes (or "IAB-nodes"). Each non-anchor network node 110 can directly communicate with the anchor network node 110 via a wireless backhaul link to access the core network, or can indirectly communicate with the anchor network node 110 via one or more other non-anchor network nodes 110 and an associated wireless backhaul link forming a backhaul path to the core network. Some anchor network nodes 110 or other non-anchor network nodes 110 can also directly communicate with one or more UEs 120 via a wireless access link carrying access services. For example, network resources used for wireless communication (such as time resources, frequency resources, and / or spatial resources) can be shared between the access link and the backhaul link.

[0050] In some examples, any network node 110 relaying communication may be referred to as a relay network node, a relay station, or simply a repeater. A repeater may receive communications from an upstream station (e.g., another network node 110 or UE 120) and transmit communications to a downstream station (e.g., UE 120 or another network node 110). In this case, the wireless communication network 100 may include or be referred to as a "multi-hop network." Figure 1 In the example shown, network node 110d (e.g., a relay network node) can communicate with network node 110a (e.g., a macro network node) and UE 120d to facilitate communication between network node 110a and UE 120d. Additionally or alternatively, UE 120 can be a relay station capable of relaying transmissions to or from other UE 120s, or can operate as such a relay station. UE 120 relaying communication can be referred to as a UE repeater or relay UE, etc.

[0051] UE 120 may be physically distributed throughout the wireless communication network 100, and each UE 120 may be stationary or mobile. UE 120 may be, may include, an access terminal, another terminal, a mobile station, or a subscriber unit, or may be included in an access terminal, another terminal, a mobile station, or a subscriber unit. UE 120 may be, or may include, a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smart wristband and / or smart jewelry (such as a smart ring or smart bracelet)), an entertainment device (e.g., a music device, a video device and / or a satellite radio), an extended reality (XR) device, a vehicle component or sensor, a smart meter or sensor, industrial manufacturing equipment, a Global Navigation Satellite System (GNSS) device (such as a Global Positioning System device or another type of positioning device), a UE function of a network node, and / or any other suitable device or function that can communicate via a wireless medium, or may be coupled to them.

[0052] UE 120 and / or network node 110 may include one or more chips, system-on-a-chip (SoC), chipsets, packages, or devices that individually or collectively constitute or include a processing system. The processing system includes processor (or “processing”) circuitry in the form of one or more processors, microprocessors, processing units (such as central processing units (CPUs), graphics processing units (GPUs), neural processing units (NPUs), and / or digital signal processors (DSPs)), processing blocks, application-specific integrated circuits (ASICs), programmable logic devices (PLDs) (such as field-programmable gate arrays (FPGAs)), or other discrete gate or transistor logic components or circuits (all of which are generally referred to herein individually as “processors” or collectively as “processors” or “processor circuitry”). One or more of these processors may be individually or collectively configured to perform the various functions or operations described herein. A group of processors that can be configured or configured to perform a set of functions may include a first processor that can be configured or configured to perform a first function in the set, and a second processor that can be configured or configured to perform a second function in the set, or may include the entire group of processors that are configured or configured to perform the set of functions.

[0053] The processing system may also include memory circuitry in the form of one or more memory devices, memory blocks, memory elements, or other discrete gate or transistor logic components or circuits, each of which may include tangible storage media such as random access memory (RAM) or read-only memory (ROM) or combinations thereof (all of which are generally referred to herein individually as "memory" or collectively as "memory" or "memory circuitry"). One or more of these memories may be coupled to one or more processors in the processor (e.g., operatively coupled, communicatively coupled, electronically coupled, or electrically coupled) and may store processor-executable code (such as software) individually or collectively, which, when executed by one or more processors in the processor, may configure one or more processors in the processor to perform the various functions or operations described herein. Additionally or alternatively, in some examples, one or more processors in the processor may be pre-configured to perform the various functions or operations described herein without being configured by software. The processing system may also include or be coupled to one or more modems (such as Wi-Fi (e.g., IEEE compliant) modems or cellular (e.g., 3GPP 4G LTE, 5G, or 6G compliant) modems). In some embodiments, one or more processors of the processing system include or implement one or more modems among the modems. The processing system may also include, or be coupled to, multiple radio components (collectively, “radio components”), multiple RF chains, or multiple transceivers, each of which may in turn be coupled to one or more antennas among multiple antennas. In some embodiments, one or more processors of the processing system include or implement one or more of the radio components, RF chains, or transceivers. UE 120 may be included or may be contained in a housing that houses components associated with UE 120, including the processing system.

[0054] Some UEs 120 can be considered as Machine Type Communication (MTC) UEs, Evolved or Enhanced Machine Type Communication (eMTC) UEs, Further Enhanced eMTC (feMTC) UEs, or Enhanced feMTC (efeMTC) UEs, or further evolutions thereof, all of which may be referred to simply as "MTC UEs". MTC UEs can be, may include, robots, unmanned aerial vehicles or drones, remote devices, sensors, instruments, monitors and / or location tags, or may be included in or coupled to them. Some UEs 120 can be considered as IoT devices and / or may be implemented as NB-IoT (Narrowband IoT) devices. IoT UEs or NB-IoT devices can be, may include, or may be included in or coupled to the following: industrial machines, appliances, refrigerators, doorbell camera devices, home automation devices and / or lighting fixtures, etc. Some UEs 120 may be considered customer premises equipment, which may include telecommunications equipment installed at a customer location (such as a home or office) to enable access to a service provider’s network (such as being included in or communicating with the wireless communication network 100).

[0055] Some UEs 120 can be categorized according to different categories associated with varying levels of complexity and / or capabilities. Category 1 UEs 120 facilitate large-scale IoT within the wireless communication network 100 and offer lower complexity and / or cost compared to Category 2 UEs 120. Category 2 UEs 120 may include mission-critical IoT devices capable of URLLC, eMBB, and / or precise positioning within the wireless communication network 100, legacy UEs, baseline UEs, high-level UEs, advanced UEs, full-capability UEs, and / or premium UEs. Category 3 UEs 120 may possess intermediate-level complexity and / or capabilities (e.g., capabilities between Category 1 and Category 2 UEs 120). Category 3 UEs 120 may be referred to as reduced-capability UEs (“RedCap UEs”), intermediate-level UEs, NR lightweight UEs, and / or NR simplified UEs, etc. RedCap UEs reduce the gap in functionality and complexity between NB-IoT devices and / or eMTC UEs and mission-critical IoT devices and / or premium UEs. RedCap UEs can include, for example, wearable devices, IoT devices, industrial sensors, and / or cameras associated with limited bandwidth, power capacity, and / or transmission range. RedCap UEs can support healthcare environments, building automation, power distribution, process automation, transportation and logistics, and / or smart city deployments, among others.

[0056] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly with each other using sidelink communication (e.g., without communicating through a network node 110 acting as an intermediary). As an example, UE 120a can send data, control information, or other signaling directly to UE 120e as sidelink communication. This contrasts with, for example, UE 120a first sending data to network node 110 in UL communication, and then that network node sending data to UE 120e in DL communication. In various examples, UE 120 can use peer-to-peer (P2P) communication protocols, device-to-device (D2D) communication protocols, vehicle-to-everything (V2X) communication protocols (which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, and / or vehicle-to-pedestrian (V2P) protocols), and / or mesh network communication protocols to send and receive sidelink communication. In some deployments and configurations, network node 110 may schedule and / or allocate resources for sidelink communication between UEs 120 in the wireless communication network 100. In some other deployments and configurations, UE 120 (instead of network node 110) may perform or cooperate with or negotiate with one or more other UEs to perform scheduling operations, resource selection operations, and / or other operations for sidelink communication.

[0057] In various examples, in addition to half-duplex operation, some network nodes and UEs in the wireless communication network 100, including network node 110 and UE 120, can also be configured for full-duplex operation. Network node 110 or UE 120 operating in half-duplex mode can perform only one of transmission or reception during a specific time resource period (such as a specific time slot, symbol, or other time period). Half-duplex operation may involve time division duplex (TDD), where the DL transmission of network node 110 and the UL transmission of UE 120 do not occur in the same time resource (i.e., the transmissions do not overlap in time). In contrast, network node 110 or UE 120 operating in full-duplex mode can transmit and receive communications concurrently (e.g., within the same time resource). By operating in full-duplex mode, network node 110 and / or UE 120 can generally increase the capacity of the network and radio access links. In some examples, full-duplex operation may involve frequency division duplex (FDD), in which network node 110 performs DL transmission in a first frequency band or on a first component carrier, and UE 120 performs transmission in a second frequency band or on a second component carrier, the second frequency band or the second component carrier being different from the first frequency band or the first component carrier, respectively. In some examples, full-duplex operation may be enabled for UE 120 but not for network node 110. For example, UE 120 may simultaneously transmit UL to the first network node 110 and receive DL transmissions from the second network node 110 in the same time resources. In some other examples, full-duplex operation may be enabled for network node 110 but not for UE 120. For example, network node 110 may simultaneously transmit DL to the first UE 120 and receive UL transmissions from the second UE 120 in the same time resources. In some other examples, full-duplex operation may be enabled for both network node 110 and UE 120.

[0058] In some examples, UE 120 and network node 110 can perform MIMO communication. "MIMO" generally refers to the simultaneous transmission or reception of multiple signals (such as multiple layers or multiple data streams) using the same time and frequency resources. MIMO techniques typically utilize multipath propagation. MIMO can be implemented using various spatial processing or spatial multiplexing operations. In some examples, MIMO can support simultaneous transmission to multiple receivers, which is called multi-user MIMO (MU-MIMO). Some RATs can employ advanced MIMO techniques such as mTRP operations (including redundant transmission or reception on multiple TRPs), reciprocity in the time or frequency domain, single-frequency network (SFN) transmission, or noncoherent joint transmission (NC-JT).

[0059] In some aspects, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may: receive configuration information indicating a power offset for each resource block between one or more first resource blocks used to carry ACK / NACK feedback and one or more second resource blocks in common interleaving; and use that power offset and a transmit power depending on whether a downlink path loss value is indicated in the configuration information to transmit PSFCH transmission in the one or more first resource blocks and the one or more second resource blocks. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0060] In some respects, network node 110 may include communication manager 150. As described in more detail elsewhere herein, communication manager 150 may: generate configuration information for PSFCH indicating the power offset per resource block between one or more first resource blocks used to carry ACK / NACK feedback and one or more second resource blocks in common interleaving; and transmit the configuration information. Additionally or alternatively, communication manager 150 may perform one or more other operations described herein.

[0061] As indicated above, Figure 1 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 1 The examples described are different.

[0062] Figure 2 This is an illustration of an example network node 110 communicating with an example UE 120 in a wireless network according to this disclosure.

[0063] like Figure 2As shown, network node 110 may include a data source 212, a transmit processor 214, a transmit (TX) MIMO processor 216, a set of modems 232 (shown as 232a to 232t, where t ≥ 1), a set of antennas 234 (shown as 234a to 234v, where v ≥ 1), a MIMO detector 236, a receive processor 238, a data sink 239, a controller / processor 240, a memory 242, a communication unit 244, a scheduler 246, and / or a communication manager 150, etc. In some configurations, one or a combination of antennas 234, modems 232, MIMO detectors 236, receive processors 238, transmit processors 214, and / or TX MIMO processors 216 may be included in a transceiver of network node 110. This transceiver may be under the control of and used by one or more processors (such as controller / processor 240), and in some respects, in conjunction with processor-readable code stored in memory 242, perform aspects of the methods, processes, and / or operations described herein. In some respects, network node 110 may include one or more interfaces, communication components and / or other components that facilitate communication with UE 120 or another network node.

[0064] The terms “processor,” “controller,” or “controller / processor” can refer to one or more controllers and / or one or more processors. For example, references to “a / the processor,” “a / the controller / processor,” etc. (in the singular) should be understood as referring to a combination of… Figure 2 The processor described refers to any one or more processors, such as a single processor or a combination of multiple different processors. The reference to "one or more processors" should be understood as a combination of references. Figure 2 Any one or more processors described herein. For example, one or more processors of network node 110 may include transmit processor 214, TX MIMO processor 216, MIMO detector 236, receive processor 238, and / or controller / processor 240. Similarly, one or more processors of UE 120 may include MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, and / or controller / processor 280.

[0065] In some aspects, a single processor can perform all operations described as being performed by one or more processors. In some aspects, a first set of one or more processors can perform a first operation described as being performed by that one or more processors, and a second set of one or more processors can perform a second operation described as being performed by that one or more processors. The first set of processors and the second set of processors can be the same set of processors or can be different sets of processors. The reference to "one or more memories" should be understood to refer to any one or more memories of the corresponding device, such as those in combination. Figure 2 The memory described. For example, an operation described as being performed by one or more memories can be performed by the same subset of the one or more memories or by different subsets of the one or more memories.

[0066] For downlink communication from network node 110 to UE 120, transmitting processor 214 may receive data (“downlink data”) intended for use by UE 120 (or a group of UEs including UE 120) from data source 212 (such as a data pipeline or data queue). In some examples, transmitting processor 214 may select one or more modulation and decoding schemes (MCS) for UE 120 based on one or more channel quality indicators (CQIs) received from UE 120. Network node 110 may process the data (e.g., including encoding the data) according to the MCS selected for UE 120 for transmission to UE 120 on the downlink, thereby generating data symbols. Transmitting processor 214 may process system information (e.g., semi-static resource partitioning information (SRPI)) and / or control information (e.g., CQI requests, grants, and / or upper-layer signaling) and provide overhead symbols and / or control symbols. The transmitting processor 214 can generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS), demodulation reference signals (DMRS), or channel state information (CSI) reference signals (CSI-RS)) and / or synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)).

[0067] The TX MIMO processor 216 can perform space processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols where applicable, and can output a set of symbol streams (e.g., TA set of output symbol streams is provided to modem 232. For example, each output symbol stream may be provided to a corresponding modulator component (shown as MOD) of modem 232. Each modem 232 may use the corresponding modulator component to process (e.g., modulate) the corresponding output symbol stream (e.g., for orthogonal frequency division multiplexing (OFDM)) to obtain an output sample stream. Each modem 232 may further use the corresponding modulator component to process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sample stream to obtain a time-domain downlink signal. Modems 232a to 232t may transmit the set of downlink signals (e.g., via a set of corresponding antennas 234) together. T (One downlink signal).

[0068] Downlink signaling may include DCI communication, MAC control element (MAC-CE) communication, RRC communication, downlink reference signaling, or another type of downlink communication. Downlink signaling may be transmitted on the PDCCH, PDSCH, and / or another downlink channel. Downlink signaling may carry one or more transport blocks (TBs) of data. A TB may be a data unit transmitted via the air interface in the wireless communication network 100. A data stream (e.g., from data source 212) may be encoded into multiple TBs for transmission via the air interface. The number of TBs used to carry data associated with a particular data stream may be associated with a TB size shared by multiple TBs. The TB size may be based on the radio channel conditions of the air interface, the MCS used to encode the data, downlink resources allocated for transmitting data, and / or other parameters, or otherwise associated with them. Generally, a larger TB size allows for a larger amount of data to be transmitted in a single transmission, reducing signaling overhead. However, a larger TB size may be more prone to transmission and / or reception errors than a smaller TB size, but such errors can be mitigated through more robust error correction techniques.

[0069] For uplink communication from UE 120 to network node 110, the uplink signal from UE 120 may be received by antenna 234, processed by modem 232 (e.g., demodulator component of modem 232, shown as DEMOD), detected where applicable by MIMO detector 236 (e.g., receive (Rx) MIMO processor), and / or further processed by receive processor 238 to obtain decoded data and / or control information. Receive processor 238 may provide the decoded data to data sink 239 (which may be a data pipeline, data queue, and / or another type of data sink) and provide the decoded control information to processors such as controller / processor 240.

[0070] Network node 110 may use scheduler 246 to schedule one or more UEs 120 for downlink or uplink communication. In some aspects, scheduler 246 may use DCI to dynamically schedule DL transmissions to and / or UL transmissions from UE 120. In some examples, scheduler 246 may allocate repetitive time-domain and / or frequency-domain resources for UE 120 to transmit and / or receive communication using RRC configuration (e.g., semi-static configuration), for example, to perform semi-persistent scheduling (SPS) or to configure configuration grant (CG) for UE 120.

[0071] One or more of the following may be included in the RF chain of network node 110: transmit processor 214, TX MIMO processor 216, modem 232, antenna 234, MIMO detector 236, receive processor 238, and / or controller / processor 240. The RF chain may include one or more filters, mixers, oscillators, amplifiers, analog-to-digital converters (ADCs), and / or other devices for converting analog signals (such as those used for transmission or reception via an air interface) to digital signals (such as those used for processing by one or more processors of network node 110). In some aspects, the RF chain may be a transceiver of network node 110, or may be included in such a transceiver.

[0072] In some examples, network node 110 may use communication unit 244 to communicate with the core network and / or other network nodes. Communication unit 244 may support wired and / or wireless communication protocols and / or connections, such as Ethernet, fiber optic, Common Public Radio Interface (CPRI), and / or wired or wireless backhaul, etc. Network node 110 may use communication unit 244 to send and / or receive data associated with UE 120, or to perform network control signaling, etc. Communication unit 244 may include transceivers and / or interfaces, such as network interfaces.

[0073] UE 120 may include a set of antennas 252 (shown as antennas 252a to 252r, where r ≥ 1), a set of modems 254 (shown as modems 254a to 254u, where u ≥ 1), a MIMO detector 256, a receive processor 258, a data sink 260, a data source 262, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, a memory 282, and / or a communication manager 140, etc. One or more components of UE 120 may be included in housing 284. In some aspects, one or a combination of antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, or TX MIMO processor 266 may be included in a transceiver included in UE 120. The transceiver may be under the control of and used by one or more processors (such as controller / processor 280), and in some respects, may perform aspects of the methods, procedures, or operations described herein in conjunction with processor-readable code stored in memory 282. In some respects, UE 120 may include another interface, another communication component, and / or another component that facilitates communication with network node 110 and / or another UE 120.

[0074] For downlink communication from network node 110 to UE 120, a set of antennas 252 can receive downlink communication or signals from network node 110, and can transmit a set of received downlink signals (e.g., R Each received signal is provided to a set of modems 254. For example, each received signal may be provided to a corresponding demodulator component (shown as DEMOD) of modem 254. Each modem 254 may use the corresponding demodulator component to condition (e.g., filter, amplify, down-convert, and / or digitize) the received signal to obtain an input sample. Each modem 254 may use the corresponding demodulator component to further demodulate or process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 may obtain the received symbols from the set of modems 254, may perform MIMO detection on the received symbols where applicable, and may provide the detected symbols. Receiver processor 258 may process (e.g., decode) the detected symbols, may provide the decoded data of UE 120 to data sink 260 (which may include data pipelines, data queues, and / or applications executed on UE 120), and may provide decoding control information and system information to controller / processor 280.

[0075] For uplink communication from UE 120 to network node 110, the transmitting processor 264 may receive and process data (“uplink data”) from data source 262 (such as data pipelines, data queues, and / or applications running on UE 120) and control information from controller / processor 280. The control information may include one or more parameters, feedback, one or more signal measurements, and / or other types of control information. In some aspects, the receiving processor 258 and / or controller / processor 280 may determine one or more parameters related to the transmission of uplink communication for received signals (such as those received from network node 110 or another UE). These one or more parameters may include a Reference Signal Received Power (RSRP) parameter, a Received Signal Strength Indicator (RSSI) parameter, a Reference Signal Received Quality (RSRQ) parameter, a Channel Quality Indicator (CQI) parameter, or a Transmit Power Control (TPC) parameter, etc. The control information may include indications of the RSRP parameter, RSSI parameter, RSRQ parameter, CQI parameter, TPC parameter, and / or another parameter. Control information can facilitate parameter selection and / or scheduling for UE 120 by network node 110.

[0076] Transmit processor 264 can generate reference symbols for one or more reference signals, such as uplink DMRS, uplink sounding reference signal (SRS), and / or another type of reference signal. Symbols from transmit processor 264 can be pre-decoded by TX MIMO processor 266 where applicable, and further processed by a set of modems 254 (e.g., for DFT-s-OFDM or CP-OFDM). TX MIMO processor 266 can perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols where applicable, and can provide a set of output symbol streams (e.g., ...) to a set of modems 254. U Each output symbol stream may be provided to a corresponding modulator component (shown as MOD) of modem 254. Each modem 254 may use the corresponding modulator component to process (e.g., modulate) the corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 254 may further use the corresponding modulator component to process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sample stream to obtain an uplink signal.

[0077] Modems 254a to 254u can transmit a set of uplink signals via a corresponding set of antennas 252 (e.g., R One uplink signal or UUplink signals may include UCI communication, MAC-CE communication, RRC communication, or another type of uplink communication. Uplink signals may be transmitted on PUSCH, PUCCH, and / or another type of uplink channel. Uplink signals may carry one or more TBs of data. Sidelink data and control transmission (i.e., transmission directly between two or more UEs 120) may typically use techniques similar to those described for uplink data and control transmission, and may use sidelink-specific channels such as the Physical Sidelink Shared Channel (PSSCH), Physical Sidelink Control Channel (PSCCH), and / or PSFCH.

[0078] One or more antennas in the set of antennas 252 or the set of antennas 234 may include one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, etc., or may be included in one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, or with one or more transmitting or receiving components (such as...) Figure 2 An antenna module is a combination of one or more antenna elements coupled to one or more components. As used herein, "antenna" can mean one or more antennas, one or more antenna panels, one or more antenna groups, one or more collections of antenna elements, or one or more antenna arrays. "Antenna panel" can mean a group of antennas (such as antenna elements) arranged in an array or panel that can facilitate beamforming by manipulating the parameters of that group of antennas. "Antenna module" can mean a circuit that includes one or more antennas, and may also include one or more other components (such as filters, amplifiers, or processors) associated with integrating the antenna module into a wireless communication device.

[0079] In some examples, each antenna element of antenna 234 or antenna 252 may include one or more sub-elements for radiating or receiving radio frequency signals. For example, a single antenna element may include a first sub-element cross-polarized with a second sub-element, which can be used to independently transmit cross-polarized signals. Antenna elements may include patch antennas, dipole antennas, and / or other types of antennas arranged in a linear pattern, a two-dimensional pattern, or another pattern. The spacing between antenna elements can allow signals with a desired wavelength transmitted individually by the antenna elements to interact or interfere (e.g., to form a desired beam) in various directions. For example, given a desired wavelength or frequency range, the spacing may provide a quarter wavelength, half a wavelength, or another fraction of the wavelength between adjacent antenna elements to allow desired constructive and destructive interference modes of signals transmitted by individual antenna elements within that desired range.

[0080] The amplitude and / or phase of signals transmitted via antenna elements and / or sub-elements can be modulated and (e.g., by manipulating phase shifts, phase offsets, and / or amplitudes) shifted relative to each other to generate one or more beams; this is known as beamforming. The term "beam" can refer to the directional transmission of a wireless signal toward a receiving device or otherwise in a desired direction. "Beam" can also generally refer to the direction associated with such directional signal transmission, the set of directional resources associated with the signal transmission (e.g., angle of arrival, horizontal direction, and / or vertical direction), and / or a set of parameters indicating one or more aspects of the directional signal, the direction associated with the signal, and / or the set of directional resources associated with the signal. In some implementations, antenna elements can be individually selected or deselected for the directional transmission of a signal (or multiple signals) by controlling the amplitude of one or more corresponding amplifiers and / or the phase of the signal to form one or more beams. The shape of the beam (such as amplitude, width, and / or the presence of sidelobes) and / or the direction of the beam (such as the angle of the beam relative to the surface of the antenna array) can be dynamically controlled by modifying the phase shifts, phase offsets, and / or amplitudes of multiple signals relative to each other.

[0081] Different UEs 120 or network nodes 110 may include different numbers of antenna elements. For example, UE 120 may include a single antenna element, two antenna elements, four antenna elements, eight antenna elements, or different numbers of antenna elements. Similarly, network node 110 may include eight antenna elements, 24 antenna elements, 64 antenna elements, 128 antenna elements, or different numbers of antenna elements. Generally speaking, a larger number of antenna elements provides increased control over the parameters used for beamforming compared to a smaller number of antenna elements, while a smaller number of antenna elements may be less complex to implement and can use less power. Multiple antenna elements can support multi-layer transmission, in which the same time and frequency resources are used to spatially multiplex a first layer of communication (which may include a first data stream) and a second layer of communication (which may include a second data stream).

[0082] Although Figure 2 The boxes in the diagram are illustrated as different components, but the functions described above with respect to these boxes may be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by or under the control of controller / processor 280.

[0083] Figure 3 This is an illustration of an example distributed base station architecture 300 according to this disclosure. One or more components of the example distributed base station architecture 300 may be, may include, or may be included in one or more network nodes (such as one or more network nodes 110). The distributed base station architecture 300 may include a CU 310, which may communicate directly with the core network 320 via a backhaul link, or may communicate indirectly with the core network 320 via one or more distributed control units (such as non-RT RIC 350 and / or near-RT RIC 370 associated with a Service Management and Orchestration (SMO) framework 360 (e.g., via an E2 link)). The CU 310 may communicate with one or more DU 330 via a corresponding midhaul link (such as via an F1 interface). Each DU 330 may communicate with one or more RU 340 via a corresponding fronthaul link. Each RU 340 may communicate with one or more UE 120 via a corresponding RF access link. In some deployments, a UE 120 may be served simultaneously by multiple RU 340s.

[0084] Each component of the disassembled base station architecture 300 (including CU 310, DU 330, RU 340, near-RT RIC 370, non-RT RIC 350, and SMO frame 360) may include one or more interfaces or be coupled to such interfaces for receiving or transmitting signals, such as data or information, via wired or wireless transmission media.

[0085] In some respects, the CU 310 can be logically divided into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units can communicate bidirectionally with the CU-CP units via an interface such as an E1 interface. The CU 310 can be deployed to communicate with one or more DU 330s for network control and signaling, as needed. Each DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RU 340s. For example, the DU 330 may host various layers, such as the RLC layer, MAC layer, or one or more PHY layers (such as one or more high PHY layers or one or more low PHY layers). Each layer (which may also be referred to as a module) can be implemented using an interface for signaling to other layers (and modules) hosted by the DU 330, or for signaling to control functions hosted by the CU 310. Each RU 340 may implement lower-layer functionality. In some respects, the real-time and non-real-time aspects of communication with the control plane and user plane of the RU 340 can be controlled by the corresponding DU 330.

[0086] The SMO framework 360 supports RAN deployment and provisioning for both non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 360 supports the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via operation and maintenance interfaces such as the O1 interface. For virtualized network elements, the SMO framework 360 can interact with cloud computing platforms such as the Open Cloud (O-Cloud) platform 390 to perform network element lifecycle management (such as instantiating virtualized network elements) via cloud computing platform interfaces such as the O2 interface. Virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 350, and / or near-RT RIC 370. In some aspects, the SMO framework 360 can communicate with hardware aspects of the 4G RAN, 5G NR RAN, and / or 6G RAN (such as the Open eNB (O-eNB) 380) via the O1 interface. Additionally or alternatively, the SMO framework 360 can communicate directly with each of one or more RUs 340 via the corresponding O1 interface. In some deployments, this configuration enables each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

[0087] The non-RT RIC 350 may include or implement logical functions that enable non-real-time control and optimization of RAN elements and resources, including artificial intelligence / machine learning (AI / ML) workflows for model training and updates, and / or policy-based guidance of applications and / or features in the near-RT RIC 370. The non-RT RIC 350 may be coupled to or communicate with the near-RT RIC 370, such as via an A1 interface. The near-RT RIC 370 may include or implement logical functions that enable near real-time control and optimization of RAN elements and resources via an interface, such as an E2 interface, through data collection and actions, connecting one or more CU 310s, one or more DU 330s, and / or O-eNBs to the near-RT RIC 370.

[0088] In some respects, to generate AI / ML models to be deployed in the near-RT RIC 370, the non-RT RIC 350 may receive parameters or external enrichment information from an external server. This information can be utilized by the near-RT RIC 370 and may be received from non-network data sources or network functions at the SMO framework 360 or the non-RT RIC 350. In some examples, the non-RT RIC 350 or near-RT RIC 370 may tune RAN behavior or performance. For example, the non-RT RIC 350 may monitor long-term trends and patterns in performance and may employ AI / ML models to perform corrective actions via the SMO framework 360 (such as reconfiguration via the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0089] As indicated above, Figure 3 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 3 The examples described are different.

[0090] Network node 110, network node 110's controller / processor 240, UE 120, UE 120's controller / processor 280, CU 310, DU 330, RU 340 or Figure 1 , Figure 2 or Figure 3 Any other component may implement one or more techniques associated with power control for the PSFCH or perform one or more operations associated with such power control, as described in more detail elsewhere herein. For example, the controller / processor 240 of network node 110, the controller / processor 280 of UE 120, Figure 2 Any other component, CU 310, DU 330, or RU 340, may (alone or in combination with one or more other processors) execute or boot, for example...

Memory 282 may store data and program code for UE 120. In some examples, memory 242 or memory 282 may include a non-transitory computer-readable medium storing instruction sets (e.g., code or program code) for wireless communication. Memory 242 may include one or more memories, such as a single memory or multiple different memories (of the same or different types). Memory 282 may include one or more memories, such as a single memory or multiple different memories (of the same or different types). For example, the instruction set may be made to be executed by one or more processors of network node 110, UE 120, CU 310, DU 330, or RU 340 (e.g., directly, or after compilation, transformation, or interpretation). Figure 8 The process 800 Figure 9 The process 900 or other processes as described herein. In some examples, the execution instructions may include run instructions, transform instructions, compile instructions, and / or interpret instructions, etc.

[0091] In some aspects, UE 120 includes: components for receiving configuration information indicating a power offset for each resource block between one or more first resource blocks used to carry ACK / NACK feedback and one or more second resource blocks in common interleaving; and / or components for: using the power offset and transmitting PSFCH transmissions in the one or more first resource blocks and the one or more second resource blocks using a transmit power depending on whether a downlink path loss value is indicated in the configuration information. Components for the UE to perform the operations described herein may include, for example, one or more of the following: a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0092] In some aspects, network node 110 includes: components for generating configuration information for PSFCH, the configuration information indicating the power offset of each resource block between one or more first resource blocks used to carry ACK / NACK feedback and one or more second resource blocks in common interleaving; and / or components for transmitting the configuration information. Components for the network node to perform the operations described herein may include, for example, one or more of the following: communication manager 150, transmit processor 214, TX MIMO processor 216, modem 232, antenna 234, MIMO detector 236, receive processor 238, controller / processor 240, memory 242, or scheduler 246.

[0093] Figure 4 This is a diagram illustrating example 400 of sidelink communication according to this disclosure.

[0094] like Figure 4 As shown, the first UE 405-1 can communicate with the second UE 405-2 (and one or more other UEs 405) via one or more sidelink channels 410. UEs 405-1 and 405-2 can communicate using one or more sidelink channels 410 for P2P communication, D2D communication, V2X communication (e.g., which may include V2V communication, V2I communication, and / or V2P communication), and / or mesh networking. In some aspects, UEs 405 (e.g., UEs 405-1 and / or UEs 405-2) can correspond to one or more other UEs (such as UE 120) described elsewhere herein. In some aspects, one or more sidelink channels 410 can use a PC5 interface and / or can operate in a high-frequency band (e.g., the 5.9 GHz band). Additionally or alternatively, UEs 405 can use Global Navigation Satellite System (GNSS) timing to synchronize the timing of transmission time intervals (TTIs) (e.g., frames, subframes, time slots, or symbols).

[0095] like Figure 4As further shown, one or more sidelink channels 410 may include a Physical Sidelink Control Channel (PSCCH) 415, a PSSCH 420, and / or a PSFCH 425. The PSCCH 415 may be used to convey control information, similar to the PDCCH and / or PUCCH used for cellular communication with network node 110 via an access link or access channel. The PSSCH 420 may be used to convey data, similar to the PDSCH and / or PUSCH used for cellular communication with network node 110 via an access link or access channel. For example, the PSCCH 415 may carry sidelink control information (SCI) 430, which may indicate various control information for sidelink communication, such as one or more resources (e.g., time resources, frequency resources, and / or spatial resources), on which transport blocks (TBs) 435 may be carried on the PSSCH 420. TBs 435 may include data. PSFCH 425 can be used to communicate sidelink feedback 440, such as HARQ feedback (e.g., acknowledgment or negative acknowledgment (ACK / NACK) information), transmit power control (TPC), and / or scheduling request (SR).

[0096] Although shown on PSCCH 415, SCI 430 may include multiple communications at different levels, such as Level 1 SCI (SCI-1) and Level 2 SCI (SCI-2) in some respects. SCI-1 may be transmitted on PSCCH 415. SCI-2 may be transmitted on PSSCH 420. SCI-1 may include indications of one or more resources (e.g., time resources, frequency resources, and / or spatial resources) on, for example, PSSCH 420; information for decoding sidelink communications on the PSSCH; Quality of Service (QoS) priority values; resource reservation periods; PSSCH Demodulation Reference Signal (DMRS) mode; SCI format for SCI-2; β offset for SCI-2; number of PSSCH DMRS ports; and / or MCS. SCI-2 may include information associated with data transmission on PSSCH 420, such as HARQ procedure ID, New Data Indicator (NDI), source identifier, destination identifier, and / or Channel State Information (CSI) report triggering.

[0097] In some aspects, one or more sidelink channels 410 may use resource pools. For example, scheduling assignments (e.g., included in SCI 430) may be transmitted across time using specific resource blocks (RBs) in a subchannel. In some aspects, data transmissions associated with scheduling assignments (e.g., on PSSCH 420) may (e.g., using frequency division multiplexing) occupy adjacent RBs in the same subframe as the scheduling assignment. In some aspects, scheduling assignments and associated data transmissions are not transmitted on adjacent RBs.

[0098] In some aspects, UE 405 may operate using a sidelink transmission mode (e.g., mode 1), in which resource selection and / or scheduling is performed by network node 110 (e.g., a base station, CU, or DU). For example, UE 405 may receive permission for sidelink channel access and / or scheduling from network node 110 (e.g., directly or via one or more network nodes) (e.g., permission for configuration in a DCI or in an RRC message). In some aspects, UE 405 may operate using a transmission mode (e.g., mode 2), in which resource selection and / or scheduling is performed by UE 405 (e.g., not by network node 110). In some aspects, UE 405 may perform resource selection and / or scheduling by sensing the availability of channels for transmission. For example, UE 405 can measure RSSI parameters (e.g., sidelink-RSSI (S-RSSI) parameters) associated with various sidelink channels, RSRP parameters (e.g., PSSCH-RSRP parameters) associated with various sidelink channels, and / or RSRQ parameters (e.g., PSSCH-RSRQ parameters) associated with various sidelink channels, and can select the channel for transmitting sidelink communication based at least in part on the measurements.

[0099] Alternatively or additionally, UE 405 may use the SCI 430 received in PSCCH 415 to perform resource selection and / or scheduling, which may indicate the occupied resources and / or channel parameters. Alternatively or additionally, UE 405 may perform resource selection and / or scheduling by determining the Channel Busy Ratio (CBR) associated with various sidelink channels, which may be used for rate control (e.g., by indicating the maximum number of resource blocks that UE 405 may use for a specific set of subframes).

[0100] In a transmission mode where resource selection and / or scheduling is performed by UE 405, UE 405 may generate sidelink grants and transmit the grants in SCI 430. Sidelink grants may indicate one or more parameters (e.g., transmission parameters) to be used for an upcoming sidelink transmission, such as one or more resource blocks (e.g., for TB 435) to be used for an upcoming sidelink transmission on PSSCH 420, one or more subframes to be used for an upcoming sidelink transmission, and / or the MCS to be used for an upcoming sidelink transmission. In some aspects, UE 405 may generate sidelink grants indicating one or more parameters for semi-persistent scheduling (SPS), such as the periodicity of sidelink transmissions. Additionally or alternatively, UE 405 may generate sidelink grants for event-driven scheduling (such as for on-demand sidelink messages).

[0101] As indicated above, Figure 4 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 4 The examples described are different.

[0102] Figure 5 This is a diagram illustrating example 500 of sidelink communication and access link communication according to this disclosure.

[0103] like Figure 5 As shown, the transmitter (Tx) / receiver (Rx) UE 505 and the Rx / Tx UE 510 can communicate with each other via a side link, as described above. Figure 4 As described herein. As further shown, in some sidelink modes, network node 110 may communicate with Tx / Rx UE 505, such as via a first access link (e.g., directly or via one or more network nodes). Additionally or alternatively, in some sidelink modes, network node 110 may communicate with Rx / Tx UE 510, such as via a first access link (e.g., directly or via one or more network nodes). Tx / Rx UE 505 and / or Rx / Tx UE 510 may correspond to one or more UEs, such as UE 120, as described elsewhere herein. Thus, a direct link between UEs 120 (e.g., via a PC5 interface) may be referred to as a sidelink, and a direct link between network 110 and UE 120 (e.g., via a Uu interface) may be referred to as an access link. Sidelink communication may be transmitted via a sidelink, and access link communication may be transmitted via an access link. Access link communication can be downlink communication (from network node 110 to UE 120) or uplink communication (from UE 120 to network node 110).

[0104] As indicated above, Figure 5 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 5 The descriptions are different.

[0105] Figure 6 This is a diagram illustrating example 600 of an interleaving configuration associated with a PSFCH waveform according to this disclosure. In some aspects, the PSFCH waveform can be combined with... Figure 4 The described PSFCH 425 is associated with this.

[0106] Access to unlicensed spectrum may be based at least in part on interleaving. Interleaving may refer to the basic unit of air interface resource allocation, such as air interface resource allocation characterized at least in part by frequency spans (e.g., which may be divided into subbands and / or subcarriers), time spans (e.g., which may be divided into subtime spans, such as time slots and / or symbols), and / or any combination of one or more physical resource blocks (PRBs). Access to interleaving may be based at least in part on interleaving configurations, such as the interleaving configuration associated with the PSFCH waveform described with respect to Example 600. The horizontal axis of the interleaving configuration represents the interleaved RBs, and the vertical axis of the interleaving configuration represents the cyclic shift (CS) pairs of resources.

[0107] Interweaving may include N Interleaved Resource Blocks (IRBs), of which N It is an integer. For example, as shown by reference numeral 602 in the attached figure, the first group of IRBs (e.g., N One IRB (individual IRBs) may be included in the common interweaving shown in solid lines, and as indicated by reference numeral 604 in the figure, a second group of IRBs (e.g., N One or a different number of IRBs may be included in the configuration interleaving (e.g., dedicated interleaving) shown in dashed lines. In some respects, configuration interleaving N An IRB may be partitioned as described below. A common interleaving may be interleaved with a configuration interleaving at least in part based on one or more IRBs of the common interleaving being adjacent to one or more IRBs of the configuration interleaving. Example 600 exemplifies a common interleaving as having 10 partitions and a configuration interleaving as having two partitions (where the partitions correspond to rows in Example 600), but other examples may include configuration interleavings having the same number of partitions as the common interleaving and / or more partitions than the common interleaving. In at least one example, the common interleaving and the configuration interleaving include an equal number of partitions. Alternatively or additionally, the common interleaving and the configuration interleaving may include an equal number of IRBs and / or different numbers of IRBs from each other.

[0108] The resources of the common interleaving can be available to any device (e.g., any UE 120), and the resources of the configuration interleaving can be assigned and / or directed to one or more specific UEs. That is, any UE can transmit PSFCH based at least in part on all the resources of the common interleaving and / or one or more resources of the configuration interleaving. Thus, any UE can use one or more PRBs and / or IRBs included in the common interleaving shown by reference numeral 602, and / or a specific UE can use one or more PRBs and / or IRBs included in the configuration interleaving shown by reference numeral 604. For example, a UE can use resources in the common interleaving and / or configuration interleaving to transmit any combination of ACK / NACK feedback indications and / or dummy signals to satisfy power spectral density (PSD) conditions. A “dummy signal” can refer to a signal without an expected receiver. In some examples, a dummy signal can be based at least in part on a pattern and / or copy of information not intended for recovery. That is, a dummy signal can be a signal intended (e.g., at a specific transmit power level) to occupy a specific portion of the spectrum without intending to transmit information.

[0109] The PSFCH waveform in Example 600 may be based at least in part on a first number of consecutive PRBs for the corresponding ACK / NACK feedback indication on the configuration interleaving shown by reference numeral 604 and / or a second number of PSFCH IRBs assigned to dummy signals on the common interleaving (e.g., the common interleaving shown by reference numeral 602). The first number of consecutive PRBs for the corresponding ACK / NACK feedback indication may be an integer denoted as K3, and in some respects, may be a configurable integer. For illustration, the K3 value and / or mode used by UE 120 to transmit the ACK / NACK feedback indication may be RRC configured. Alternatively or additionally, the second number of PSFCH IRBs may be calculated as follows: N –K3, where N This refers to the number of IRBs in an interleaving as described above. In at least one example, the PSFCH waveform can be at least partially based on K3 equal to... N The fully interleaved PSFCH waveform.

[0110] like Figure 6As shown, UE 120 can transmit a PSFCH waveform comprising one or more dummy signals (shown diagonally as dummy signal 606-1, dummy signal 606-2, dummy signal 606-3 and dummy signal 606-m, where m is an integer) in one or more IRBs of common interleaving as indicated by reference numeral 602, and K3 ACK / NACK feedback indications (shown in dashed mode as ACK / NACK feedback indication 608-1 and ACK / NACK feedback indication 608-2) in one or more IRBs of configuration interleaving as indicated by reference numeral 604. In some aspects, the PSFCH waveform can be configured using more than one IRB, which is assigned to the ACK / NACK feedback indications to mitigate low transmit power at least in part based on PSD conditions (e.g., meeting a threshold of dBm / MHz). Alternatively or additionally, and at least in part based on the reduced peak-to-average power ratio (PAPR) of side-link transmissions, the UE may identify a cyclic shift ramp configuration (e.g., a cyclic shift ramp across the interleaving) for transmissions at least in part based on common interleaving as indicated by reference numeral 602 and / or at least in part based on configuration interleaving as indicated by reference numeral 604.

[0111] The UE can utilize the downlink path loss value of the PSFCH (e.g., a value indicating the loss of signal power on the PSFCH) (labeled as...). dl-P0-PSFCH Configure it using ) . When the active-side link bandwidth portion is in the serving cell c When (e.g., as specified by 3GPP Technical Specification (TS) 38.213, Clause 7.1.1), except when the UE is configured to detect the serving cell. c When using DCI format 0_0 to monitor PDCCH, the reference signal resource is used by the UE to determine the serving cell. c The reference signal resource for the power of PUSCH transmission in DCI format 0_0 scheduling, and when the UE is not configured to detect the serving cell. c When using DCI format 0_0 to monitor PDCCH, the reference signal resource corresponds to the reference signal resource of the synchronization signal (SS) / physical broadcast channel (PBCH) block used by the UE to obtain the main information block (MIB). If... dl-P0-PSFCH Provided to the UE, the transmit power required by the PSFCH can be obtained through [dBm] is calculated, where yes dl-P0-PSFCH The value, It is the configured scaling factor ( dl-Alpha-PSFCH The value of ) (if provided, otherwise ),and (Indicates the bandwidth portion) b carrierf Service Community c The associated path loss estimate, where This represents the reference signal used to estimate path loss.

[0112] When the UE supports up to a maximum of [number] PSFCH transmission times Simultaneous PSFCH transmission, and the UE has the option to transmit within a given PSFCH transmission time. When there are multiple PSFCH transmissions, the UE can select the PSFCH transmission timings in ascending order of priority for actual transmission. One PSFCH. In the first case, when Less than or equal to )and dl-P0- PSFCH When configuring the UE (e.g., pre-configured), if The total transmit power of each PSFCH is equal to or less than the UE's maximum transmit power (marked as...). (Right now )),but and Otherwise (if the total transmit power is greater than the UE's maximum transmit power), the UE may first use the ascending order of the corresponding priority field values ​​on the PSFCH transmission with HARQ-ACK information (if any), and then autonomously determine the order using the ascending order of the priority values ​​on the PSFCH transmission with conflict information (e.g., information indicating that the PSFCH transmission is conflicted or scheduled to conflict in sidelink resources). Send one PSFCH, making , in (for () is a priority value for PSFCH with HARQ-ACK information. The number of PSFCHs, and (for ) is a priority value for PSFCH with conflict information.

It can be defined as satisfying The maximum value, where (for example, specified by [8-1,3GPP TS 38.101-1]) For All PSFCH transmissions (if any), otherwise K It could be zero. As described above, can be [dBm] is given, where Indicates the allowed transmission power and This indicates the required transmission power.

[0113] In the second case, when and dl-P0-PSFCH When configuring the UE (e.g., pre-configuring), the UE can first select the corresponding priority field value on the PSFCH transmission with HARQ-ACK information in ascending order (if any), and then select the priority field value on the PSFCH transmission with conflict information in ascending order. One PSFCH. If The total transmit power of each PSFCH is equal to or less than (Right now, ),but and [dBm]. Otherwise (total transmit power greater than the UE's maximum transmit power), the UE can autonomously select the order of priority field values ​​on the PSFCH transmission with HARQ-ACK information (if any), followed by the order of priority field values ​​on the PSFCH transmission with conflict information (if any). Send one PSFCH, making ,in () is a priority value for PSFCH with HARQ-ACK information. The number of PSFCHs ) is a priority value for PSFCH with conflict information. The number of PSFCHs, and It is defined as described above. It can also be defined as described above.

[0114] In sidelink communication using unlicensed spectrum (SL-U), PSFCH transmission can utilize a 15kHz or 30kHz subcarrier spacing (SCS). In such examples, the UE can be configured (e.g., pre-configured) by the network node to use one or more interleavings for PSFCH transmission. In one example, the UE configuration may indicate that each PSFCH transmission will occupy one dedicated interleaving. In another example, the UE configuration may indicate that each PSFCH transmission will occupy one common interleaving and K3 dedicated PRBs. The value of K3 can be configured (e.g., pre-configured) by the network node for the UE. The value range of K3 may include at least {1, 2, 5}. Furthermore, the K3 dedicated PRBs can be on the same interleaving.

[0115] The guard band PRB can be between a common PRB and a dedicated PRB. In some examples, the UE can determine the number of guard band PRBs. Additionally or alternatively, configured (e.g., pre-configured) gaps (e.g., including zero gaps) can be between common PRBs and dedicated PRBs. In some examples, the guard band PRBs and / or gaps can be indicated by configuration for the UE (e.g., by setting bit values ​​in a bitmap used for PSFCH PRB allocation).

[0116] Multiple CS pairs can be used on K3 dedicated PRBs (e.g., as in legacy NR sidelink PSFCH transmission). In some examples, when the common-interleaved PRB and the dedicated PRB are located within the same 1MHz bandwidth, the UE can transmit only on the dedicated PRB, provided that the Occupied Channel Bandwidth (OCB) requirement is met. In some examples, PSFCH transmission on the common PRB can use reduced power.

[0117] PSSCH transmissions on non-overlapping resources can be mapped to orthogonal dedicated PRBs used for PSFCH transmissions. In some examples, PRB-level cyclic shift transitions can be used to reduce PAPR. In some examples, public PRBs can be discarded if the dedicated PRB meets OCB requirements.

[0118] For SL-U PSFCH waveforms with common interleaving (e.g., each PSFCH transmission occupies one common interleaving and K3 dedicated PRBs), the final transmit power on a common PRB can be denoted as: The final transmit power on a dedicated PRB can be labeled as ,and Can be less than or equal to As described in this article, the UE can utilize... and Configured by offset between them.

[0119] As described above, in older sidelinks, PSFCH transmission can occupy one RB. If dl-P0-PSFCH is provided to the UE, the transmit power required for PSFCH transmission can be reduced by... [dBm] is given. However, for PSFCH waveforms with common interleaving, the PSFCH transmission can occupy K3 RBs carrying ACK / NACK feedback and have (For example, a common interleaving of 10–K3) interleaved RBs. Therefore, the transmit power required for PSFCH transmission occupying K3 RBs and a common interleaving can be greater than that required for PSFCH transmission occupying one RB. K3 RBs and common interleaving ( The transmit power of each RB can be equal. = Alternatively, the transmit power per RB of the common interleaved RB may be less than the transmit power per RB of the K3 RBs.

[0120] The UE may not be able to determine how to efficiently allocate transmit power between the RB carrying ACK / NACK feedback and the common interleaved RB. Therefore, the UE may allocate too much power to transmit PSFCH in the common interleaved RB, potentially depleting the UE's battery. Furthermore, the UE may allocate insufficient power to transmit PSFCH in the RB carrying ACK / NACK feedback, which may degrade the performance of ACK / NACK feedback upon arrival at the receiving device and / or lead to retransmissions of ACK / NACK feedback that consume additional computing and / or network resources.

[0121] Some of the techniques and apparatus described herein relate to power control for the PSFCH. Some aspects more specifically relate to power control for PSFCH waveforms using common interleaving in unlicensed spectrum. In some aspects, per-RB power offsets of the PSFCH can be signaled to the UE by the network node. Per-RB power offsets can occur between RBs carrying ACK / NACK feedback and RBs in the common interleaving. Per-RB power offsets can be indicated for PSFCH transmission by the per-RB transmit power of the RBs carrying ACK / NACK feedback and the RBs in the common interleaving.

[0122] By signaling the power offset per RB to the UE, the described technique enables the UE to efficiently allocate transmit power to PSFCH transmission between the RB carrying ACK / NACK feedback and the RB in the common interleaving, thereby saving power and improving the performance of ACK / NACK feedback upon arrival at the receiving device. In addition to indicating the power offset between the RB carrying ACK / NACK feedback and the RB in the common interleaving, the power offset parameter in the signaling can also be used to indicate the absence of a power offset, thereby reducing the signaling overhead associated with the use of individual parameters.

[0123] As indicated above, Figure 6 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 6 The examples described are different.

[0124] Figure 7 This is a diagram of example 700 related to power control for the PSFCH according to this disclosure. Figure 7 As shown, network nodes (e.g., network nodes 110, CU, DU, and / or RU) can communicate with the first UE (e.g., UE 120). Figure 7As further illustrated, the first UE can communicate with a second UE (e.g., UE 120), which in turn can communicate with a network node. In some aspects, the network node, the first UE, and the second UE can be part of a wireless network (e.g., wireless network 100). The first UE and the network node, as well as the first UE and the second UE, can... Figure 7 The operation shown has been performed with a wireless connection already established.

[0125] As shown by reference numeral 705 in the attached figure, a network node may send configuration information, and a first UE may receive such configuration information. In some aspects, the first UE may receive the configuration information via one or more of the following: system information (e.g., MIB and / or System Information Block (SIB), etc.), RRC signaling, one or more MAC-CE and / or DCI, etc.

[0126] In some aspects, configuration information may indicate one or more candidate configuration and / or communication parameters. In some aspects, one or more candidate configuration and / or communication parameters may be selected, activated, and / or deactivated via subsequent indications. For example, a subsequent indication may select a candidate configuration and / or communication parameter from the one or more candidate configuration and / or communication parameters. In some aspects, subsequent indications (e.g., the indications described herein) may include dynamic indications, such as one or more MAC CEs and / or one or more DCI messages.

[0127] In some respects, configuration information may indicate that one or more first RBs (e.g., K3 RBs) carrying ACK / NACK feedback are interleaved with one or more second RBs (e.g., ...) in the common interleaving. The power offset per RB between the common interleaved RBs. As described herein, the power offset can be determined by the transmission power of the first UE for PSFCH (e.g., SL-U PSFCH waveform). For example, the power offset can be related to the transmission power of the UE for one or more PSFCH transmissions in the first RB and the second RB. The power offset can indicate the difference in transmission power between the RB used to carry ACK / NACK feedback and the RBs in the common interleaved RBs.

[0128] The power offset indicated by the configuration information can be a power offset value indicating a decibel offset. For example, the power per RB of common interleaving can be expressed as ,in It is the power per RB of the first RB, and This is the power per RB of the second RB, as described herein. Additionally or alternatively, the power offset indicated by configuration information may be a power scaling value (α). For example, the power per RB of the common interleaving may be expressed as... In some respects, the decibel offset and scaling values ​​may have a relationship with the first UE configuration and / or specified in the information allocated to the first UE. For example, this relationship may be expressed as... Therefore, if either the decibel offset or the power scaling value is indicated in the configuration information, the first UE can identify the other decibel offset or power scaling value based on this relationship.

[0129] In some respects, the decibel offset can be 0 and / or the power scaling value can be 1 to indicate the power per RB of the second RB. ) equals the power per RB of the first RB ( Alternatively, the decibel offset may be a positive value (e.g., greater than 0) and / or the power scaling value may be less than 1 (e.g., between 0 and 1, excluding 0 and 1) to indicate the power per RB of the second RB. The power per RB is less than that of the first RB. ).

[0130] In some aspects, configuration information may indicate the configuration of the PSFCH (e.g., it may indicate the PSFCH resources used for the first UE). For example, configuration information may indicate common interleaving (e.g., the time resources for common interleaving, the frequency resources for common interleaving, or the number of RBs in common interleaving). (e.g., etc.). For example, configuration information may indicate the dedicated RBs used for the first UE (e.g., time resources of the dedicated RBs, frequency resources of the dedicated RBs, interleaving involving the dedicated RBs, or the number of dedicated RBs (K3), etc.). In some aspects, configuration information may indicate downlink path loss values ​​(d1-P0-PSFCH). In other aspects, downlink path loss values ​​may not be present in the configuration information.

[0131] In some aspects, the network node may generate configuration information for the PSFCH (e.g., in unlicensed spectrum) for the first UE. In some aspects, the network node may select the configuration information for the first UE based on a capability report provided by the first UE (as described below) and / or a measurement report provided by the first UE. In some aspects, the network node may select decibel offset and / or power scaling values ​​to meet OCB requirements. For example, the network node may select decibel offset and / or power scaling values ​​such that 99% of the energy consumed (e.g., PSFCH transmission) exceeds the minimum OCB. The OCB can be calculated by measuring the minimum bandwidth containing 99% of the transmission power.

[0132] The first UE may configure itself at least in part based on configuration information. In some aspects, the first UE may be configured to perform one or more operations described herein, at least in part based on configuration information.

[0133] As shown by reference numeral 710 in the attached figure, a first UE may transmit a capability report, and a network node may receive the capability report. The capability report may indicate that the first UE supports a feature and / or one or more parameters associated with that feature. For example, capability information may indicate the capability and / or parameters for using a common-interleaved SL-U PSFCH waveform. As another example, the capability report may indicate the capability and / or parameters for transmitting PSFCH using per-RB power or transmitting PSFCH using a power offset between an RB carrying ACK / NACK feedback and an RB in the common interleaving. One or more operations described herein may be based on the capability information in the capability report. For example, the first UE may perform communication based on the capability information, or may receive configuration information based on the capability information. In some aspects, the capability report may indicate that the UE supports transmitting PSFCH waveforms using common interleaving.

[0134] In some aspects, the configuration information and / or capability report described in conjunction with reference to reference numeral 705 may include information transmitted via multiple communications. Additionally or alternatively, the network node may transmit the configuration information or communications including at least a portion of the configuration information before and / or after the first UE transmits the capability report. For example, the network node may transmit a first portion of the configuration information before the capability report, the first UE may transmit at least a portion of the capability report, and the network node may transmit a second portion of the configuration information after receiving the capability report.

[0135] As shown by reference numeral 715 in the attached figure, the second UE may transmit sidelink communication, and the first UE may receive such sidelink communication (e.g., PSSCH communication). For example, the second UE may send sidelink communication to the first UE, and the first UE may attempt to decode the sidelink communication. The first UE may generate an ACK / NACK feedback (also referred to as HARQ-ACK feedback or HARQ feedback) associated with the sidelink communication. The ACK / NACK feedback may include an ACK indicating that the first UE successfully received and decoded (e.g., transmitted on the PSSCH) the sidelink communication, or a NACK indicating that the first UE failed to receive or decode the sidelink communication.

[0136] In some aspects, sidelink communication can be communicated during a PSSCH timing event, which may be associated with a PSFCH resource used to carry ACK / NACK feedback for the PSSCH. In some aspects, the first UE may (e.g., from a sidelink resource pool not dedicated to PSFCH) select the PSFCH resource to carry the ACK / NACK feedback for the PSSCH. For example, the first UE may select the PSFCH resource based on one or more parameters configured for the first UE and / or based on a specific PSFCH resource configured for the first UE.

[0137] As shown by reference numeral 720 in the attached figure, a first UE can transmit a PSFCH transmission (e.g., a PSFCH waveform), and a second UE can receive the PSFCH transmission. The first UE can transmit the PSFCH transmission through one or more first RBs (e.g., K3 RBs) and one or more second RBs in a common interleaving (e.g., ...). PSFCH transmissions can be performed in a common interleaved RB (RB). For example, a PSFCH transmission can indicate ACK / NACK feedback in a first RB and can provide a dummy signal in a second RB in the common interleaving. The first UE can transmit PSFCH transmissions in PSFCH resources as described herein. PSFCH transmissions can use unlicensed spectrum.

[0138] The first UE may transmit the PSFCH based on a power offset. For example, the first UE may transmit the PSFCH using a per-RB transmit power at least partially based on the power offset (e.g., the per-RB transmit power may be derived using the power offset). In some aspects, the transmit power of the PSFCH transmission may be based on (e.g., depending on) whether the downlink path loss value (d1-P0-PSFCH) is provided to the first UE in the configuration information.

[0139] In some aspects, the downlink path loss value (dl-P0-PSFCH) may not exist in the configuration information (e.g., the downlink path loss value may not be provided to the first UE), and therefore, the transmit power of the PSFCH (the maximum transmit power per PSFCH) may be independent of the downlink path loss value. For example, if the downlink path loss value does not exist in the configuration information (e.g., the downlink path loss value is not provided to the first UE), the maximum transmit power per PSFCH... i can be Given, where It is the maximum transmit power of the first UE and This refers to the number of PSFCH transmissions. Therefore, the maximum transmission power can be evenly distributed across the number of PSFCH transmissions.

[0140] In some aspects (e.g., when the downlink path loss value is not present in the configuration information), the transmit power can be based on the power offset, the first number of the first RB, and the second number of the second RB. This is relative to the first RB (e.g., K3 RBs carrying ACK / NACK feedback) and the second RB (e.g., ...). The data is divided into K3 common interleaved RBs. For example, the maximum transmit power per PSFCH can be allocated among the K3 ACK / NACK bearer RBs with different weights determined by the power offset and the actual number of RBs. K3 RBs are intertwined with each other. Divide into (RBs). For example, = Therefore, the power per RB of the first RB ( ) and the power per RB of the second RB ( It can be given by the following formula:

[0141] In some aspects, the configuration information may indicate a downlink path loss value (dl-P0-PSFCH), and therefore, the transmit power of PSFCH transmissions (e.g., the transmit power required per PSFCH transmission) can be derived using the downlink path loss value. Several alternative schemes may exist for deriving the transmit power using the downlink path loss value. In a first alternative scheme, the transmit power may be independent of (e.g., independent of) a first number of first RBs and a second number of second RBs. For example, the transmit power required per PSFCH transmission may be calculated as follows: dBm (e.g., an old formula for the transmit power required per PSFCH), where µ represents the parameter set (e.g., 15kHz SCS or 30kHz SCS).

[0142] In the second alternative scheme, the transmit power can be derived using, for example, based on the number of first RBs (e.g., based on the number of ACK / NACK bearer RBs). For example, the transmit power required per PSFCH transmission can be calculated as follows: dBm. In a third alternative scheme, the transmit power can be derived using (e.g., based on) a first number of the first RBs and a second number of the second RBs scaled by the power offset (e.g., based on the number of ACK / NACK bearer RBs and the number of common interleaved RBs discounted by the power offset). For example, the transmit power required per PSFCH transmission can be calculated as follows: dBm.

[0143] In some aspects (e.g., when the downlink path loss value is provided to the first UE), the first UE can use one of a first alternative scheme, a second alternative scheme, or a third alternative scheme to calculate the transmission power (e.g., the transmission power required per PSFCH transmission), and the transmission power can be calculated based on the power offset, the first number of first RBs, and the second number of second RBs. The first RB (e.g., K3 RBs carrying ACK / NACK feedback) and the second RB (e.g., ... The power required for each PSFCH transmission can be divided into K3 ACK / NACK bearer RBs with different weights determined by the power offset and the actual number of RBs. K3 RBs are intertwined with each other. Divide into (RBs). For example, the power per RB of the first RB ( ) and the power per RB of the second RB ( It can be given by the following formula:

[0144] By signaling the power offset of each RB to the first UE, the described technique can be used to enable the first UE to efficiently allocate transmission power to PSFCH transmission between the RB carrying ACK / NACK feedback and the RB in common interleaving, thereby saving power and improving the performance of ACK / NACK feedback when it reaches the receiving device.

[0145] As indicated above, Figure 7 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 7 The examples described are different.

[0146] Figure 8 This is a diagram illustrating an example process 800 performed, for example, at a UE or a device of a UE, according to this disclosure. Example process 800 is an example of a device or UE (e.g., UE 120) performing operations associated with power control for the PSFCH.

[0147] like Figure 8 As shown, in some aspects, process 800 may include receiving configuration information indicating the power offset per resource block between one or more first resource blocks used to carry ACK / NACK feedback and one or more second resource blocks in common interleaving (box 810). For example, the UE (e.g., using...) Figure 10 The depicted receiving component 1002 and / or communication manager 1006 may receive configuration information indicating the power offset of each resource block between one or more first resource blocks carrying ACK / NACK feedback and one or more second resource blocks in common interleaving, as described above.

[0148] like Figure 8 Further, in some aspects, process 800 may include transmitting PSFCH in one or more first resource blocks and one or more second resource blocks using a power offset and a transmit power that depends on whether the downlink path loss value is indicated in the configuration information (box 820). For example, the UE (e.g., using...) Figure 10 The described transmitting component 1004 and / or communication manager 1006 can transmit PSFCH in one or more first resource blocks and one or more second resource blocks according to the power offset, as described above.

[0150] In the first aspect, the downlink path loss value is not present in the configuration information, and the transmission power used for PSFCH transmission is independent of the downlink path loss value.

[0155] In the sixth aspect, either alone or in combination with one or more of the first to fifth aspects, the transmission power is derived based on a first number of the one or more first resource blocks and a second number of the one or more second resource blocks scaled by the power offset.

[0157] In the eighth aspect, the configuration information is in the RRC signaling, either alone or in combination with one or more of the first to seventh aspects.

[0158] In the ninth aspect, the PSFCH transmission uses unlicensed spectrum, either alone or in combination with one or more of the first to eighth aspects.

Example process 900 is an example in which a device or network node (e.g., network node 110) performs operations associated with power control for the PSFCH.

For example, network nodes (e.g., using...)
