CLI reporting of MAC-CE activation

Abstract

A UE can receive a configuration of one or more SP resources for CLI and / or SI measurements, and receive a MAC-CE from a base station activating the configured one or more SP resources for CLI and / or SI measurements. The UE can measure CLI and / or SI based on the interfering signals, and report a CLI report including the measured CLI and / or SI to the base station. The UE can estimate an average CL based on an average transmission power of the interfering signals over multiple slots from an aggressor UE, and the base station can determine a CLI of the aggressor UE based on CLI reciprocity using the estimated average CL.

[0002] This application claims the benefit and priority of Greek patent application serial number 20200100547 entitled “METHODS AND APPARATUS FOR MAC-CEACTIVATION OF CLI REPORTING”, filed on September 10, 2020, which is expressly incorporated herein by reference in its entirety. Technical Field

[0003] This disclosure generally relates to communication systems, and more specifically, to a wireless communication method including activation of a Media Access Control (MAC) control element (CE) (MAC-CE) for Cross-Link Interference (CLI) Reporting. Background Technology

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, and Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems.

[0005] These multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different wireless devices to communicate at the municipal, national, regional, and even global levels. An example telecommunications standard is 5G New Radio (NR). 5G NR is part of the Continuous Mobile Broadband Evolution (CMB) initiative released by the 3rd Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with the Internet of Things (IoT)), and other requirements. 5G NR includes services associated with enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), and ultra-reliable low-latency communications (URLLC). Some aspects of 5G NR can be based on the 4G Long Term Evolution (LTE) standard. Further improvements to 5G NR technology are needed. These improvements can also be applied to other multiple access technologies and telecommunications standards that adopt these technologies. Summary of the Invention

[0006] The following is a simplified outline of one or more aspects to provide a basic understanding of these aspects. This outline is not a comprehensive overview of all anticipated aspects, and is neither intended to identify key or critical elements of all aspects, nor to depict the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed descriptions that follow.

[0007] In one aspect of this disclosure, a method, computer-readable medium, and apparatus are provided. A UE can receive from a base station the configuration of one or more semi-persistent (SP) resources for cross-link interference (CLI) or self-interference (SI) measurements, receive a first media access control (MAC) control element (CE) (MAC-CE) activating at least one configured SP resource for CLI or SI measurements, and perform CLI or SI measurement activities in the at least one configured SP resource activated by the MAC-CE. The UE can report a CLI report to the base station, the CLI report including at least one CLI component measured from at least one interference signal received from the MAC-CE activated SP resource. The UE can estimate an average CL based on the average transmission power of the interference signals over multiple time slots, and the base station can use the estimated average CL to determine the CLI of other UEs based on CLI reciprocity.

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

[0031] The detailed description set forth below with reference to the accompanying drawings is intended as a description of various configurations and not as representing the only configuration in which the concepts described herein can be practiced. The detailed description includes specific details used to provide a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts can be practiced without these specific details. In some cases, well-known structures and components are shown in block diagram form to avoid obscuring such concepts.

[0032] Several aspects of a telecommunications system will now be presented with reference to various apparatuses and methods. These apparatuses and methods will be described in detail below and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively, “elements”). These elements can be implemented using electronic hardware, computer software, or any combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the entire system.

[0033] For example, an element, or any part of an element, or any combination of elements, can be implemented as a "processing system" including one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, system-on-a-chip (SoCs), baseband processors, field-programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functions throughout this disclosure. One or more processors in the processing system can execute software. Software should be interpreted broadly as instructions, instruction sets, code, code segments, program code, programs, subroutines, software components, application programs, software applications, software packages, routines, subroutines, objects, executable programs, threads of execution, procedures, functions, etc., whether or not referred to as software, firmware, middleware, microcode, hardware description languages, or others.

[0034] Therefore, in one or more example embodiments, the described functionality can be implemented in hardware, software, or any combination thereof. If implemented in software, the functionality can be stored on or encoded as one or more instructions or code on a computer-readable medium. A computer-readable medium includes a computer storage medium. The storage medium can be any available medium that is accessible to a computer. By way of example, and not limitation, such a computer-readable medium can include random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disc storage, magnetic disk storage, other magnetic storage devices, combinations of computer-readable medium types, or any other medium that can be used to store computer-executable code in the form of computer-accessible instructions or data structures.

[0035] While aspects and implementations are described herein by way of example, those skilled in the art will understand that additional implementations and use cases may arise in many different arrangements and scenarios. The aspects described herein can be implemented across many different platform types, devices, systems, shapes, sizes, and package arrangements. For example, implementations and / or uses may arise via integrated chip implementations and other devices based on non-modular components (e.g., end-user devices, vehicles, communication devices, computing devices, industrial devices, retail / purchasing devices, medical devices, artificial intelligence (AI) enabling devices, etc.). While some examples may or may not be specific to a particular use case or application, broad applicability of the described aspects may emerge. The scope of implementations can range from chip-level or modular components to non-modular, non-chip-level implementations, and also to aggregated, distributed, or original equipment manufacturer (OEM) devices or systems that integrate one or more of the described aspects. In some practical settings, devices incorporating the described aspects and features may also include additional components and features for implementing and practicing the claimed and described aspects. For example, the transmission and reception of wireless signals necessarily involve multiple components for analog and digital purposes (e.g., hardware components including antennas, RF chains, power amplifiers, modulators, buffers, processors(multiple), interleavers, adders / summers, etc.). The aspects described herein are intended to be implemented in a variety of devices, chip-level components, systems, distributed arrangements, aggregated or decomposed components, end-user equipment, etc., of different sizes, shapes, and structures.

[0036] Figure 1This is a schematic diagram illustrating an example of a wireless communication system and access network 100. The wireless communication system (also known as a wireless wide area network (WWAN)) includes a base station 102, a user interface unit (UE) 104, an evolved packet core (EPC) 160, and another core network 190 (e.g., a 5G core (5GC)). Base station 102 may include macro cells (high-power cellular base stations) and / or small cells (low-power cellular base stations). Macro cells include base stations. Small cells include femtocells, picocells, and microcells.

[0037] Base station 102 configured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) can interface with EPC 160 via a first backhaul link 132 (e.g., S1 interface). Base station 102 configured for 5G NR (collectively referred to as Next Generation RAN (NG-RAN)) can interface with core network 190 via a second backhaul link 184. Among other functions, base station 102 can perform one or more of the following functions: user data transmission, radio channel encryption and decryption, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection establishment and release, load balancing, distribution of non-access stratum (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS), subscriber and device tracking, RAN information management (RIM), paging, location, and warning message delivery. Base station 102 can communicate with each other directly or indirectly (e.g., via EPC 160 or core network 190) via third backhaul link 134 (e.g., X2 interface). First backhaul link 132, second backhaul link 184 and third backhaul link 134 can be wired or wireless.

[0038] Base station 102 can wirelessly communicate with UE 104. Each base station 102 can provide communication coverage for a corresponding geographic coverage area 110. Overlapping geographic coverage areas 110 may exist. For example, a small cell 102' may have a coverage area 110' that overlaps with the coverage areas 110 of one or more macro base stations 102. A network that includes small cells and macro cells can be referred to as a heterogeneous network. A heterogeneous network may also include a Home Evolution Node B (eNB) (HeNB), which can provide services to a restricted group called a Closed Subscriber Group (CSG). The communication link 120 between base station 102 and UE 104 may include uplink (UL) (also called reverse link) transmission from UE 104 to base station 102 and / or downlink (DL) (also called forward link) transmission from base station 102 to UE 104. The communication link 120 may use multiple-input multiple-output (MIMO) antenna technologies including spatial multiplexing, beamforming, and / or transmit diversity. The communication link may use one or more carriers. Base station 102 / UE 104 can use spectrum with up to Y MHz (e.g., 5, 10, 15, 20, 100, 400 MHz, etc.) bandwidth allocated to each carrier in carrier aggregation, which has up to a total of Yx MHz (x component carriers) for transmission in each direction. Carriers may be adjacent to each other or not. Carrier allocation may be asymmetrical relative to DL and UL (e.g., more or fewer carriers may be allocated to DL than to UL). Component carriers may include primary component carriers and one or more secondary component carriers. The primary component carrier may be referred to as the primary cell (PCell), and the secondary component carriers may be referred to as secondary cells (SCells).

[0039] Some UEs 104 can communicate with each other using device-to-device (D2D) communication link 158. D2D communication link 158 can use DL / UL WWAN spectrum. D2D communication link 158 can use one or more sidelink channels, such as Physical Sidelink Broadcast Channel (PSBCH), Physical Sidelink Discovery Channel (PSDCH), Physical Sidelink Shared Channel (PSSCH), and Physical Sidelink Control Channel (PSCCH). D2D communication can be conducted through various wireless D2D communication systems, such as, for example, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the IEEE 802.11 standard, LTE, or NR.

[0040] The wireless communication system may also include a Wi-Fi access point (AP) 150 that communicates with a Wi-Fi station (STA) 152 via a communication link 154, for example, in an unlicensed spectrum such as 5 GHz. When communicating in an unlicensed spectrum, the STA 152 / AP 150 may perform a free channel assessment (CCA) before communication to determine whether the channel is available.

[0041] Small cell 102' can operate in licensed and / or unlicensed spectrum. When operating in unlicensed spectrum, small cell 102' can employ NR and use the same unlicensed spectrum (e.g., 5 GHz, etc.) as the Wi-Fi AP 150. Small cell 102' employing NR in unlicensed spectrum can improve the coverage and / or increase the capacity of the access network.

[0042] The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc., based on frequency / wavelength. In 5G NR, two initial operating bands were designated as frequency range names FR1 (410MHz–7.125GHz) and FR2 (24.25GHz–52.6GHz). Although a portion of FR1 is greater than 6GHz, it is often referred to (interchangeably) as the “sub-6GHz” band in various documents and articles. Similar naming issues sometimes arise with FR2; although FR2 differs from the Extremely High Frequency (EHF) band (30GHz–300GHz) recognized as a “millimeter wave” band by the International Telecommunication Union (ITU), it is often referred to (interchangeably) as the “millimeter wave” band in documents and articles.

[0043] The frequencies between FR1 and FR2 are generally referred to as the intermediate frequency band (IF). Recent 5G NR studies have identified the operating band for these IF frequencies as the frequency range FR3 (7.125 GHz – 24.25 GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, and thus can effectively extend the characteristics of FR1 and / or FR2 to the IF frequencies. Furthermore, higher frequency bands are currently being explored to extend 5G NR operation above 52.6 GHz. For example, three higher operating bands have been identified as the frequency range names FR4a or FR4-1 (52.6 GHz – 71 GHz), FR4 (52.6 GHz – 114.25 GHz), and FR5 (114.25 GHz – 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0044] In light of the foregoing, unless otherwise specified, it should be understood that, as used herein, the terms "sub-6GHz," etc., can broadly refer to frequencies that may be less than 6GHz, within FR1, or may include intermediate frequency band frequencies. Furthermore, unless otherwise specified, it should be understood that, as used herein, the terms "millimeter wave," etc., can broadly refer to frequencies that may include intermediate frequency band frequencies, within FR2, FR4, FR4-a, or FR4-1 and / or FR5, or within the EHF band.

[0045] Base station 102, whether a small cell 102' or a large cell (e.g., a macro base station), may include and / or be referred to as an eNB, gNodeB (gNB), or other types of base station. Some base stations (such as gNB 180) may operate in conventional sub-6 GHz spectrum, millimeter wave frequencies, and / or near-millimeter wave frequencies communicating with UE 104. When gNB 180 operates in millimeter wave or near-millimeter wave frequencies, gNB 180 may be referred to as a millimeter wave base station. Millimeter wave base station 180 may utilize beamforming 182 with UE 104 to compensate for path loss and short range. Base station 180 and UE 104 may each include multiple antennas, such as antenna elements, antenna panels, and / or antenna arrays, to facilitate beamforming.

[0046] Base station 180 can transmit beamformed signals to UE 104 in one or more transmit directions 182'. UE 104 can receive beamformed signals from base station 180 in one or more receive directions 182'. UE 104 can also transmit beamformed signals to base station 180 in one or more transmit directions. Base station 180 can receive beamformed signals from UE 104 in one or more receive directions. Base station 180 / UE 104 can perform beamforming to determine the optimal receive and transmit directions for each of base station 180 / UE 104. The transmit and receive directions of base station 180 can be the same or different. The transmit and receive directions of UE 104 can be the same or different.

[0047] EPC 160 may include Mobility Management Entity (MME) 162, other MMEs 164, Serving Gateway 166, Multimedia Broadcast Multicast Service (MBMS) Gateway 168, Broadcast Multicast Service Center (BM-SC) 170, and Packet Data Network (PDN) Gateway 172. MME 162 can communicate with Home Subscriber Server (HSS) 174. MME 162 is the control node that handles signaling between UE 104 and EPC 160. Typically, MME 162 provides bearer and connection management. All user Internet Protocol (IP) packets are transmitted through Serving Gateway 166, which is itself connected to PDN Gateway 172. PDN Gateway 172 provides UE IP address allocation and other functions. PDN Gateway 172 and BM-SC 170 are connected to IP Service 176. IP Service 176 may include the Internet, intranet, IP Multimedia Subsystem (IMS), PS streaming service, and / or other IP services. The BM-SC 170 provides functionality for MBMS user service provisioning and delivery. It can serve as an entry point for content provider MBMS transmissions, authorize and initiate MBMS bearer services within a Public Land Mobile Network (PLMN), and schedule MBMS transmissions. The MBMS gateway 168 can distribute MBMS services to base stations 102 belonging to Multicast-Broadcast Single Frequency Network (MBSFN) areas belonging to broadcast-specific services, and can be responsible for session management (start / stop) and collecting billing information related to eMBMS.

[0048] The core network 190 may include Access and Mobility Management Functions (AMF) 192, other AMFs 193, Session Management Functions (SMF) 194, and User Plane Functions (UPF) 195. AMF 192 may communicate with Unified Data Management (UDM) 196. AMF 192 is the control node that handles signaling between UE 104 and the core network 190. Typically, AMF 192 provides QoS flow and session management. All user Internet Protocol (IP) packets are transmitted through UPF 195. UPF 195 provides UE IP address allocation and other functions. UPF 195 connects to IP service 197. IP service 197 may include the Internet, intranet, IP Multimedia Subsystem (IMS), Packet Switched (PS) Streaming (PSS) service, and / or other IP services.

[0049] Base stations may include and / or be referred to as gNB, Node B, eNB, access point, base transceiver, radio base station, radio transceiver, transceiver function, Basic Services Set (BSS), Extended Services Set (ESS), Transmitter Receiver Point (TRP), or some other suitable terminology. Base station 102 provides UE 104 with access to EPC 160 or core network 190. Examples of UE 104 include cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, GPS devices, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablets, smart devices, wearable devices, vehicles, electricity meters, air pumps, large or small kitchen appliances, medical devices, implants, sensors / actuators, displays, or any other similarly functional devices. Some of UE 104 may be referred to as IoT devices (e.g., parking meters, air pumps, toasters, vehicles, heart monitors, etc.). UE 104 may also be referred to as a station, mobile station, subscriber station, mobile unit, subscriber unit, radio unit, remote unit, mobile device, radio device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, radio terminal, remote terminal, handheld device, user agent, mobile client, client, or some other suitable terminology. In some scenarios, the term UE may also be applied to one or more accompanying devices in a device constellation arrangement. One or more of these devices may jointly access the network and / or individually access the network.

[0050] Refer again Figure 1In some aspects, UE 104 may include an SP CLI / SI resource activation component 198 configured to receive from a base station a configuration for at least one SP resource for CLI or SI measurement, receive from the base station a first MAC-CE activating the SP resource for at least one configuration for CLI or SI measurement, perform CLI or SI measurement activities in the at least one configuration of the SP resource activated by the MAC-CE, and report a CLI report to the base station, the CLI report including at least one CLI component measured from at least one interference signal received from the SP resource activated by the MAC-CE. In some aspects, base station 180 may include an SP CLI / SI resource activation component 199 configured to configure at least one SP resource for CLI or SI measurement for a first UE, send to the first UE a first MAC-CE CLI report activating the at least one configuration of the SP resource for CLI or SI measurement, the CLI report including at least one CLI component measured from at least one interference signal received from the SP resource activated by the MAC-CE. Although the following description may focus on 5G NR, the concepts described herein can be applied to other similar fields, such as LTE, LTE-A, CDMA, GSM and other wireless technologies.

[0051] Figure 2A This is a schematic diagram 200 illustrating an example of the first subframe within the 5G NR frame structure. Figure 2B This is a schematic diagram 230 illustrating an example of a DL channel within a 5G NR subframe. Figure 2C This is a schematic diagram 250 illustrating an example of the second subframe within the 5G NR frame structure. Figure 2D This is a schematic diagram 280 illustrating an example of a UL channel within a 5G NR subframe. The 5G NR frame structure can be Frequency Division Duplex (FDD), where for a specific set of subcarriers (carrier system bandwidth), subframes within that set are dedicated to either DL or UL; or it can be Time Division Duplex (TDD), where for a specific set of subcarriers (carrier system bandwidth), subframes within that set are dedicated to both DL and UL. Figure 2A , 2CIn the provided example, the 5G NR frame structure is assumed to be TDD, where subframe 4 is configured with slot format 28 (primarily DL), where D is DL, U is UL, and F is flexibly used between DL / UL, and subframe 3 is configured with slot format 1 (all UL). Although subframes 3 and 4 are shown with slot formats 1 and 28 respectively, any particular subframe can be configured with any of the various available slot formats 0-61. Slot formats 0 and 1 are all DL and UL, respectively. Other slot formats 2-61 include a mixture of DL, UL, and flexible symbols. The UE is configured with a slot format (dynamically via DL control information (DCI) or semi-statically / statically via Radio Resource Control (RRC) signaling) via the received Slot Format Indicator (SFI). Note that the following description also applies to the TDD 5G NR frame structure.

[0052] Figure 2A-2D The frame structure is illustrated, and aspects of this disclosure are applicable to other wireless communication technologies that may have different frame structures and / or different channels. A frame (10 ms) can be divided into 10 equal-sized subframes (1 ms). Each subframe may include one or more time slots. Subframes may also include micro-time slots, which may include 7, 4, or 2 symbols. Each time slot may include 14 or 12 symbols, depending on whether the cyclic prefix (CP) is normal or extended. For normal CP, each time slot may include 14 symbols, while for extended CP, each time slot may include 12 symbols. Symbols on the DL may be CP Orthogonal Frequency Division Multiplexing (OFDM) (CP-OFDM) symbols. Symbols on the UL may be CP-OFDM symbols (for high-throughput scenarios) or Discrete Fourier Transform (DFT) Extended OFDM (DFT-s-OFDM) symbols (also known as Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols) (for power-constrained scenarios; limited to single-stream transmission). The number of time slots within a subframe is based on the CP and the digital scheme. The digital scheme defines the subcarrier spacing (SCS), and in practice, the symbol length / duration, which is equal to 1 / SCS.

[0053] 0 15 Normal 1 30 Normal 2 60 Normal, extended 3 120 Normal 4 240 Normal

[0054] For a normal CP (14 symbols / slot), different digital schemes μ0 to 4 allow 1, 2, 4, 8, and 16 slots per subframe, respectively. For the extended CP, digital scheme 2 allows 4 slots per subframe. Therefore, for the normal CP and digital scheme μ, there are 14 symbols per slot and 2 slots per subframe. μ One time slot. The subcarrier spacing can be equal to 2. μ*15kHz, where μ is the digital scheme from 0 to 4. Therefore, the subcarrier spacing is 15kHz for digital scheme μ=0 and 240kHz for digital scheme μ=4. The symbol length / duration is inversely proportional to the subcarrier spacing. Figure 2A-2D Examples are provided for a normal CP with 14 symbols per slot and a digital scheme μ=2 with 4 slots per subframe. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs. Within a set of frames, there can be one or more different bandwidth portions (BWPs) of frequency division multiplexing (see...). Figure 2B Each BWP may have a specific digital scheme and CP (normal or extended).

[0055] A resource grid can be used to represent the frame structure. Each time slot consists of a resource block (RB) that extends 12 consecutive subcarriers (also known as a physical RB (PRB)). The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0056] like Figure 2A As shown, some REs carry reference (pilot) signals (RS) for the UE. RSs may include demodulation RS (DM-RS) (indicated as R for a particular configuration, but other DM-RS configurations are possible) and channel state information reference signals (CSI-RS) for channel estimation at the UE. RSs may also include beam measurement RS (BRS), beam refinement RS (BRRS), and phase tracking RS (PT-RS).

[0057] Figure 2BExamples of various DL channels within a subframe of a frame are illustrated. The Physical Downlink Control Channel (PDCCH) carries the DCI within one or more Control Channel Elements (CCEs) (e.g., 1, 2, 4, 8, or 16 CCEs), each CCE comprising six RE Groups (REGs), each REG comprising 12 consecutive REs in the OFDM symbols of the RB. A PDCCH within a BWP can be referred to as a Control Resource Set (CORESET). The UE is configured to monitor PDCCH candidates in the PDCCH search space (e.g., the common search space, the UE-specific search space) during PDCCH monitoring on the CORESET, where the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs can be located at higher and / or lower frequencies across the channel bandwidth. The Primary Synchronization Signal (PSS) can be within symbol 2 of a specific subframe of the frame. UE 104 uses the PSS to determine subframe / symbol timing and physical layer identification. The Secondary Synchronization Signal (SSS) can be within symbol 4 of a specific subframe of the frame. The UE uses the SSS to determine the Physical Layer Cell Identity Group Number and radio frame timing. Based on the Physical Layer Identifier and Physical Layer Cell Identity Group Number, the UE can determine the Physical Cell Identifier (PCI). Based on the PCI, the UE can determine the location of the DM-RS. The Physical Broadcast Channel (PBCH), carrying the Master Information Block (MIB), can be logically grouped with the PSS and SSS to form a Synchronization Signal (SS) / PBCH block (also known as an SS block (SSB)). The MIB provides multiple RBs and System Frame Numbers (SFNs) in the system bandwidth. The Physical Downlink Shared Channel (PDSCH) carries user data, broadcast system information such as System Information Blocks (SIBs) not transmitted via the PBCH, and paging messages.

[0058] like Figure 2C As shown, some REs carry DM-RS (indicated as R for a specific configuration, but other DM-RS configurations are possible) for channel estimation at the base station. The UE can transmit DM-RS for the Physical Uplink Control Channel (PUCCH) and DM-RS for the Physical Uplink Shared Channel (PUSCH). The PUSCH DM-RS can be transmitted in the first one or two symbols of the PUSCH. The PUCCH DM-RS can be transmitted in different configurations depending on whether a short or long PUCCH is transmitted and the specific PUCCH format used. The UE can transmit a Sounding Reference Signal (SRS). The SRS can be transmitted in the last symbol of a subframe. The SRS can have a comb structure, and the UE can transmit the SRS on one of the comb structures. The SRS can be used by the base station for channel quality estimation to enable frequency-dependent scheduling on the UL.

[0059] Figure 2DThe illustration shows examples of various UL channels within a subframe of a frame. The PUCCH can be positioned as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicators (CQI), precoding matrix indicators (PMI), rank indicators (RI), and hybrid automatic repeat request (HARQ) acknowledgment (ACK) feedback (i.e., one or more HARQ ACK bits indicating one or more ACKs and / or negative ACKs (NACKs)). The PUCCH carries data and can also be used to carry buffer status reports (BSR), power headroom reports (PHR), and / or UCIs.

[0060] Figure 3 This is a block diagram of base station 310 communicating with UE 350 in the access network. In the DL, IP packets from EPC 160 can be provided to controller / processor 375. Controller / processor 375 implements Layer 3 and Layer 2 functions. Layer 3 includes the Radio Resource Control (RRC) layer, and Layer 2 includes the Service Data Adaptation Protocol (SDAP) layer, Packet Data Convergence Protocol (PDCP) layer, Radio Link Control (RLC) layer, and Media Access Control (MAC) layer. The controller / processor 375 provides RRC layer functions associated with broadcasting system information (e.g., MIB, SIB), RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), measurement configuration for inter-Radio Access Technology (RAT) mobility and UE measurement reports; PDCP layer functions associated with header compression / decompression, security (encryption, decryption, integrity protection, integrity verification), and handover support functions; RLC layer functions associated with transmission of upper-layer packet data units (PDUs), error correction via ARQ, concatenation, segmentation, and reassembly of RLC service data units (SDUs), resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functions associated with mapping between logical channels and transport channels, multiplexing MAC SDUs onto transport blocks (TBs), demultiplexing MAC SDUs from TBs, scheduling information reporting, error correction via HARQ, priority handling, and logical channel priority.

[0061] Transmit (TX) processor 316 and receive (RX) processor 370 implement Layer 1 functions associated with various signal processing functions. Layer 1, including the physical (PHY) layer, may include error detection on the transport channel, forward error correction (FEC) encoding / decoding of the transport channel, interleaving, rate matching, mapping to the physical channel, modulation / demodulation of the physical channel, and MIMO antenna processing. TX processor 316 processes the mapping to the signal constellation based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The encoded and modulated symbols can then be segmented into parallel streams. Each stream can then be mapped to OFDM subcarriers, multiplexed with a reference signal (e.g., a pilot) in the time and / or frequency domains, and then combined using an inverse fast Fourier transform (IFFT) to produce a physical channel carrying a time-domain OFDM symbol stream. The OFDM streams are spatially precoded to produce multiple spatial streams. The channel estimate from channel estimator 374 can be used to determine coding and modulation schemes and for spatial processing. The channel estimate can be derived from a reference signal transmitted by UE 350 and / or channel condition feedback. Each spatial stream can then be provided to a different antenna 320 via a separate transmitter 318TX. Each transmitter 318TX can modulate a radio frequency (RF) carrier with the corresponding spatial stream for transmission.

[0062] At UE 350, each receiver 354RX receives signals through its corresponding antenna 352. Each receiver 354RX recovers the information modulated onto the RF carrier and provides this information to the receive (RX) processor 356. The TX processor 368 and RX processor 356 implement Layer 1 functions associated with various signal processing functions. The RX processor 356 can perform spatial processing on this information to recover any spatial stream destined for UE 350. If multiple spatial streams are destined for UE 350, they can be combined by the RX processor 356 into a single OFDM symbol stream. The RX processor 356 then uses a Fast Fourier Transform (FFT) to transform the OFDM symbol stream from the time domain to the frequency domain. The frequency domain signal consists of a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols and reference signals on each subcarrier are recovered and demodulated by determining the most probable signal constellation points transmitted by base station 310. These soft decisions can be based on channel estimates calculated by channel estimator 358. The soft decision is then decoded and deinterleaved to recover the data and control signals originally transmitted by base station 310 on the physical channel. The data and control signals are then provided to controller / processor 359, which implements Layer 3 and Layer 2 functions.

[0063] The controller / processor 359 may be associated with a memory 360 that stores program code and data. The memory 360 may be referred to as a computer-readable medium. In the UL, the controller / processor 359 provides demultiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover IP packets from the EPC 160. The controller / processor 359 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0064] Similar to the functions described in the DL transmission combined with base station 310, controller / processor 359 provides RRC layer functions associated with system information (e.g., MIB, SIB) acquisition, RRC connection, and measurement reporting; PDCP layer functions associated with header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functions associated with upper-layer PDU transmission, error correction via ARQ, concatenation, segmentation, and reassembly of RLC SDUs, resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functions associated with mapping between logical channels and transport channels, multiplexing MAC SDUs to TBs, demultiplexing MAC SDUs from TBs, scheduling information reporting, error correction via HARQ, priority processing, and logical channel priority.

[0065] The channel estimate derived by the channel estimator 358 from the reference signal or feedback transmitted from the base station 310 can be used by the TX processor 368 to select an appropriate coding and modulation scheme and facilitate spatial processing. The spatial stream generated by the TX processor 368 can be provided to different antennas 352 via individual transmitters 354TX. Each transmitter 354TX can modulate an RF carrier with the corresponding spatial stream for transmission.

[0066] UL transmission is processed at base station 310 in a manner similar to that described in conjunction with the receiver function at UE 350. Each receiver 318RX receives signals through its corresponding antenna 320. Each receiver 318RX recovers the information modulated onto the RF carrier and provides this information to the RX processor 370.

[0067] The controller / processor 375 may be associated with a memory 376 that stores program code and data. The memory 376 may be referred to as a computer-readable medium. In the UL, the controller / processor 375 provides demultiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover IP packets from the UE 350. IP packets from the controller / processor 375 may be provided to the EPC 160. The controller / processor 375 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0068] At least one of the TX processor 368, RX processor 356, and controller / processor 359 can be configured to perform operations related to... Figure 1 The relevant aspects of 198. At least one of the TX processor 316, RX processor 370, and controller / processor 375 can be configured to perform actions related to... Figure 1 The 199 related aspects.

[0069] Figures 4A-4C The diagram illustrates various modes of full-duplex communication. Full-duplex communication supports the transmission and reception of information in the same frequency band with time overlap. This improves spectral efficiency compared to half-duplex communication, which transmits or receives information in one direction at a time without overlapping uplink and downlink communication. Due to the simultaneous Tx / Rx characteristics of full-duplex communication, the UE or base station may experience self-interference caused by signal leakage from its local transmitter to its local receiver. Furthermore, the UE or base station may also experience interference from other devices, such as transmissions from a second UE or a second base station. Such interference (e.g., self-interference or interference caused by other devices) can affect communication quality and even lead to data loss.

[0070] Figure 4A A first example of full-duplex communication 400 is shown, in which a first base station 402a communicates in full-duplex with a first UE 404a and a second UE 406a. The first base station 402a is a full-duplex base station, while the first UE 404a and the second UE 406a can be configured as half-duplex or full-duplex UEs. The second UE 406a can transmit a first uplink signal to the first base station 402a and to other base stations such as a second base station 408a near the second UE 406a. The first base station 402a transmits a downlink signal to the first UE 404a while receiving uplink signals from the second UE 406a. Base station 402a may experience self-interference from receiving some downlink signals being transmitted to UE 404a from its receiving antenna, which is receiving uplink signals from UE 406a. Base station 402a may experience additional interference due to signals from the second base station 408a. Interference may also occur at the first UE 404a based on signals from the second base station 408a and uplink signals from the second UE 406a.

[0071] Figure 4BA second example of full-duplex communication 410 is shown, in which a first base station 402b communicates with a first UE 404b in full-duplex mode. In this example, the first base station 402b is a full-duplex base station, and the first UE 404b is a full-duplex UE. The first base station 402b and the UE 404b can simultaneously receive and transmit communications that overlap temporally in the same frequency band. The base station and the UE may each experience self-interference, where transmitted signals from the device leak to a receiver at the same device. The first UE 404b may experience additional interference based on one or more signals transmitted from the second UE 406b and / or the second base station 408b adjacent to the first UE 404b.

[0072] Figure 4C A third example of full-duplex communication 420 is shown, wherein a first UE 404c is a full-duplex UE communicating with a first base station 402c and a second base station 408c. The first base station 402c and the second base station 408c can be used as multiple transmit and receive points (multiple TRPs) for UL and DL communication with UE 404c. The second base station 408c can communicate with a second UE 406c. Figure 4C In this configuration, the first UE 404c can simultaneously transmit uplink signals to the first base station 402c and receive downlink signals from the second base station 408c. Because the first and second signals are transmitted simultaneously, the first UE 404c may experience self-interference; for example, the uplink signal may leak to the UE's receiver, and may be received by the UE's receiver. The first UE 404c may also experience additional interference from the second UE 406c.

[0073] Figures 5A-5B The illustrations show a first example 500 and a second example 510 of in-band full-duplex (IBFD) resources. Figure 5C Example 520 of subband full-duplex resources is illustrated. In IBDF, signals can be transmitted and received on overlapping times and frequencies. As shown in the first example 500, the time and frequency allocation of UL resource 502 can completely overlap with the time and frequency allocation of DL resource 504. In the second example 510, the time and frequency allocation of UL resource 512 can partially overlap with the time and frequency allocation of DL resource 514.

[0074] IBFD is the opposite of Subband FD (SBFD), where uplink and downlink resources can overlap in time using different frequencies, such as... Figure 5C As shown. Figure 5CAs shown, UL resource 522 is separated from DL resource 524 by guard band 526. The guard band can be a frequency resource or a gap between UL resource 522 and DL resource 524. Separating UL and DL frequency resources with a guard band can help reduce self-interference. UL and DL resources adjacent to each other correspond to a guard bandwidth of 0. Since, for example, output signals from the UE transmitter can extend beyond the UL resource, the guard band can reduce interference experienced by the UE. Sub-band FD can also be referred to as "flexible duplex".

[0075] The aspects presented in this article can help provide self-interference mitigation. These aspects may contribute to improved isolation, such as exceeding 50 dB. Figure 6 An example of device 602 is illustrated, which includes a separate panel, such as an antenna panel, for simultaneous transmission and reception in full-duplex operation. For example, device 602 is shown as including panel #1 and panel #2. In some examples, panel #1 may be used for downlink transmission. Downlink transmission can occur at both edges of a frequency band, as shown in 600 and 610. Panel #2 may be used for uplink reception, such as using frequency resources within the band, such as in the middle of the band. Such as combining... Figure 5C The described subband full-duplex operation can be associated with isolation greater than 40 dB. For example... Figure 5C As shown, downlink and uplink resources can be in different parts of the frequency band, with a guard band between the uplink and downlink parts of the frequency band. Figure 6 The illustration shows an example set of time and frequency resources 600 including half-duplex and full-duplex cycles. For example, time period 620 includes half-duplex resources for downlink data, such that both panel #1 and panel #2 can receive downlink data during time period 620. Time period 620 includes sub-band full-duplex resources for uplink transmission (e.g., PUSCH) and downlink reception (e.g., downlink data), such that during time period 630, panel #1 can receive downlink data and panel #2 can transmit PUSCH. Time period 640 includes half-duplex resources for uplink data, such that both panel #1 and panel #2 can transmit PUSCH during time period 640. Figure 6 It also includes a graph 610 showing the signal power at frequencies, which shows the leakage of uplink and downlink signals outside the frequency range provided in the subband full-duplex resources of time period 630.

[0076] When a time slot has frequency bands for both uplink and downlink transmission, the time slot format can be called a "D+U" time slot. Downlink and uplink transmissions can occur in overlapping frequency resources, such as... Figure 5A and 5BAs shown (e.g., in-band full-duplex resources), or frequency resources that can occur in adjacent or slightly separated areas (e.g., Figure 5C (As shown) (e.g., sub-band full-duplex resources). In a particular D+U symbol, a half-duplex device can transmit in the uplink band or receive in the downlink band. In a particular D+U symbol, a full-duplex device can transmit in the uplink band and receive in the downlink band, for example, in the same symbol or in the same time slot. D+U time slots can include downlink-only symbols, uplink-only symbols, and full-duplex symbols. For example, in Figure 6 In the time period 620, one or more symbols may be extended (e.g., downlink symbols only), one or more symbols may be extended in time period 640 (e.g., uplink symbols only), and one or more symbols may be extended in time period 630 (e.g., full-duplex symbols or D+U symbols).

[0077] In some examples, the receiver can perform windowed overlap and summation (WOLA) to reduce adjacent channel leakage ratio (ACLR) for uplink signal leakage. An analog low-pass filter (LPF) can improve the dynamic range of the analog-to-digital converter (ADC). The receiver's automatic gain control (AGC) state can be improved to enhance the noise figure (NF). Digital interference cancellation, e.g., greater than 20 dB, can be used to reduce ACLR leakage. In some examples, a nonlinear model can be employed for each Tx-Rx pair.

[0078] In some examples, uplink power control can be used to mitigate self-interference. For instance, a full-duplex UE can reduce its uplink transmission power, which will reduce interference to downlink reception in full-duplex time slots through uplink power control. Similarly, a full-duplex base station can reduce downlink transmission power through downlink power control to reduce interference to uplink reception in full-duplex time slots. In some examples, different uplink power control parameters can be applied to full-duplex time slots than to half-duplex time slots. In some examples, subband power control parameters, such as uplink power control offset or scaling, can be applied to full-duplex operation and can be different from the parameters applied to half-duplex operation.

[0079] This paper presents different power control parameters, such as uplink power control parameters for each subband. These uplink power control parameters for each subband provide more control and increased flexibility to reduce self-interference, while also protecting uplink transmission.

[0080] Figure 7AAn example communication system 700 with a full-duplex base station 702 is illustrated, which includes intra-cell cross-link interference (CLI) caused by UE 706 located within the same cell coverage 710 to UE 704, and inter-cell interference from base station 708 outside the cell coverage 710. Figure 7B The illustration shows an example communication system 750, illustrating inter-cell cross-link interference from UE 716 affecting the downlink reception of UE 714. UE 714 is located in cell coverage 720 of base station 712, and UE 716 is located in cell coverage 722 of base station 718. Although not shown, full-duplex UEs may cause self-interference in their own downlink reception.

[0081] In Subband Full-Duplex (SBFD), a base station can configure downlink transmission to a UE in frequency domain resources adjacent to those used for uplink transmission to another UE. For example, in Figure 7A In this context, frequency resources used for downlink transmission to UE 704 can be adjacent to frequency sources used for uplink transmission from UE 706.

[0082] Figure 8 An example of CSI-IM resource 800 relative to full-duplex resources for wireless communication is illustrated. Intra-cell CLI can limit UE performance, for example, CLI leakage from UL transmissions from nearby users in IBFD or CLI leakage from DL transmissions from UL transmissions in SBFD mode. In SBFD and / or IBFD modes, the base station can configure CSI-IM in both UL and DL (the entire DL BWP) within a full-duplex time slot to enable FD-aware and / or FD UEs to measure different interference components. That is, the base station can configure CSI-IM throughout the entire DL BWP within a full-duplex time slot and instruct the UE to configure CSI-IM in the UL channel to measure different interference components.

[0083] In SBFD example 810, CSI-IM resource 815 includes portions 817 and 818 that may be affected by inter-cell interference and CLI leakage, and portion 816 that may primarily involve CLI interference. IBFD example 820 includes CSI-IM resource 825, which has a portion 826 affected by CLI and a portion 827 affected by inter-cell interference and CLI leakage. Intra-cell CLI may limit the performance of some UEs. (The last sentence appears to be incomplete and possibly refers to a combination of two parts.) Figure 4A , 4BAs described in 4C and 7A, CLI can originate from uplink transmissions from nearby users in IBFD mode, or from CLI leakage received in downlink transmissions in SBFD mode. For full-duplex communication, the base station can configure CSI-IM resources to extend the uplink and downlink portions of the DL BWP in full-duplex time slots. CSI-IM resources enable full-duplex-aware UE2, or a UE2 with full-duplex capability, to measure different interference components. UE2 can measure the interference level in the configured CSI-IM resources, such as 815 or 825. UE2 can calculate the contribution of CLI, for example, based on wideband or subband received signal strength indication (RSSI). For example, graph 830 showing CLI leakage at frequencies measured by UE2 shows that the signal power of the CLI leakage is strongest near the uplink channel transmitted by UE1.

[0084] Here, UE2 can be the victim UE, and UE2 can be configured to measure CLI based on uplink reference signals of nearby aggressor UEs including UE1, such as SRS transmissions. That is, the base station can configure aggressor UE1 with SRS transmissions in the UL portion and victim UE2 with CSI-IM resources. In other words, victim UE2 can detect SRS overlapping with CSI-IM resources in the CSI-IM. Therefore, the base station can configure CSI-IM to match the SRS allocation in the UL of aggressor UE1. Thus, the victim UE can measure CLI in the configured CSI-IM resources (e.g., RSSI) in portions 816, 817, 818, 826, and 827, and measure the Reference Signal Received Power (RSRP) and / or Reference Signal Received Quality (RSRQ) in the subband corresponding to the SRS transmission in portions 816 and 826.

[0085] Figure 9 An example of CSI-IM resource 900 relative to full-duplex resources for wireless communication is illustrated. In-UE CLI or self-interference can limit the performance of a full-duplex UE. In SBFD and / or IBFD modes, the base station can configure the FD-UE for self-interference measurement using CSI-IM resources. The UE measures the interference power in the configured CSI-IM resources and calculates wideband / subband self-interference, such as RSSI. The base station can also configure the FD-UE using SRS in the UL portion and CSI-IM resources matched to the SRS allocation in the SRS BW. The UE calculates self-interference based on SRS, such as RSSI, RSRP, and RSRQ.

[0086] In SBFD example 910, CSI-IM resource 915 includes portions 917 and 918 that may be subject to self-interference from CLI leakage, and portion 916 that may primarily consist of self-interference in the CLI. IBFD example 920 includes CSI-IM resource 925, which has a portion 926 of the CLI subject to self-interference and a portion 927 subject to self-interference from CLI leakage. Self-interference can limit the performance of FDUE1. (As in...) Figure 4A , 4B As described in 4C and 7A, self-interference may originate from uplink transmissions of UE1 in IBFD mode, or from CLI leakage of downlink reception from uplink transmissions of UE1 in IBFD mode. For full-duplex communication, the base station can configure CSI-IM resources to extend the uplink and downlink portions of the DL BWP in full-duplex time slots. CSI-IM resources enable full-duplex UE1 to measure different interference components. UE1 can measure the interference level in the configured CSI-IM resources, such as 915 or 925. UE1 can calculate the contribution of self-interference, for example, based on wideband or subband received signal strength indication (RSSI).

[0087] Here, UE1 can be configured to measure self-interference based on UE1's uplink reference signal (e.g., such as SRS transmission). That is, the base station can configure FD UE1 using SRS transmissions in the UL portion and CSI-IM resources. Specifically, FD UE1 can detect SRS in CSI-IMs that overlap with CSI-IM resources. The base station can configure CSI-IMs to match the SRS allocation in the UL of FD UE1. Therefore, FD UE1 can measure CLI in the configured CSI-IM resources (e.g., RSSI) in portions 916, 917, 918, 926, and 927, and measure RSRP and / or RSRQ in the subband corresponding to the SRS transmissions in portions 916 and 926.

[0088] CLI / SI reports can be based on short-term L1 reports to help base stations make scheduling decisions based on measured interference. For dynamic or time-varying systems, L1-based CLI / SI reports can improve the accuracy of base station scheduling decisions. However, L1-based CLI / SI reports may also have increased reporting overhead.

[0089] In some respects, a base station can configure a UE to report CLI / SI semi-periodically or as an average of CLI / SI. For example, a UL service model can have a periodic pattern, and conversely, a victim UE can have a periodic CLI / SI pattern. For another example, CLI / SI may be nearly constant or change slowly over N time slots. The base station may be interested in the average interference characteristics. In such cases, the base station can determine whether to configure the UE to report semi-static CLI / SI or average CLI / SI to reduce reporting overhead and obtain accurate semi-static interference measurements. For example, the base station can configure a victim UE to report CLI via UL MAC-CE (L2 reporting) and can measure the reported CLI / SI based on semi-persistent or periodic CSI-IM resources.

[0090] Figure 10A and 10B These are MAC CE 1000 and 1010 used to activate SP CSI-IM and SP SRS resources. First, Figure 10A The diagram illustrates a MAC-CE 1000 used to activate SP CSI-IM resources. The MAC-CE 1000 can be a MAC-CE for SP CSI-IM activation / deactivation, transmitted from the base station to the UE on the PDSCH. That is, the base station can send SP CSI-IM to activate / deactivate CSI-IM resources in downlink transmissions to measure CLI and / or SI. For example, the same MAC-CE can activate / deactivate SP CSI-RS for channel measurements and CSI-IM for interference measurements. Activation / deactivation can be at the resource set level. The MAC-CE 1000 can have a variable-size bitmap including an SP CSI-IM resource set ID, an IM field, and a TCI status list. The SP CSI-IM resource set ID field can contain an index (e.g., CSI-IM-ResourceSet) of the resource set containing the SP CSI-IM resources, indicating the SP CSI-IM resource set that can activate / deactivate the corresponding SP CSI-IM resources for interference measurements. The field length can be 6 bits. The IM field can indicate whether the SP CSI-IM field exists, and the TCI status list can indicate information related to receive beam management of resources in the SP CSI-RS resource set associated with reception.

[0091] Figure 10BThe diagram illustrates a MAC-CE 1010 used to activate SP SRS. MAC-CE 1010 can be used to activate / deactivate SP SRS. MAC-CE 1010 can be a MAC-CE for SP CSI-IM activation / deactivation, which is sent from the base station to the UE and / or aggressor UE on the PDSCH. That is, the base station can send a MAC-CE to the UE and / or aggressor UE to activate / deactivate the configured SP SRS in uplink transmission. Activation / deactivation can be at the resource set level. MAC-CE 1000 can have a variable-size bitmap including an SP SRS resource set ID and a list of resource IDs. The SP SRS resource set ID can indicate the SP SRS resource set ID identified by a corresponding field (e.g., SRS-ResourceSetId) that will be activated or deactivated. The field length can be 4 bits. The list of resource IDs can indicate information related to the transmission beam management of resources in the associated SP SRS resource set used for transmission and how the beam is configured.

[0092] In some aspects, the base station can configure an aggressor UE using the SP / P (SP / P) SRS resource set. The SP / P SRS can be activated / deactivated via MAC-CE. The base station can define a new field in the MAC-CE to indicate that the SRS is used for CLI measurements, and that the SRS should be transmitted at a predefined Tx power (e.g., maximum power P_cmax). Since interference depends on the channel between the UE and the aggressor UE and the uplink transmission power from the aggressor UE, CLI measurements can represent interference based on the channel between the UE and the aggressor UE. The base station can configure a victim UE using the SP CSI-IM resource set. The SP CSI-IM resource set can be activated / deactivated via MAC-CE. On one hand, the base station can use the same MAC-CE for both the CSI framework and the CLI framework. That is, the same MAC-CE can activate / deactivate both the SP CSI-RS and SP CSI-IM resources. On the other hand, the base station can configure a new MAC-CE to trigger SP CSI-IM instead of SP CSI-RS. The MAC-CE can also include a TCI status list for the associated CSI-IM resource set. That is, the TCI status list can include TCI status for multiple SP CSI-IM resources separately. On the one hand, if the UE is both the victim and the aggressor of SI measurements, the base station can define a new MAC-CE to trigger both SP SRS and SP CSI-IM for CLI / SI measurements.

[0093] In some aspects, the base station can configure a victim UE to measure CLI and / or SI using SP / P CSI-IM resource sets. The victim UE can report one or more CLI values ​​or measurements via uplink MAC-CE based on trigger events. When the UE is configured with P / SP CSI-IM resources, the base station can define trigger events for CLI reporting. Trigger events may include, but are not limited to, measured interference exceeding a certain threshold, changes in CLI due to a factor upon timer expiration, periodic timers, and / or deactivation of the SP CSI-IM resource set used for CLI measurements. That is, if measured interference exceeds a certain threshold, if a timer has expired and the CLI is changed by a factor, based on a periodic timer, and / or when the SP CSI-IM set used for CLI measurements is deactivated, the UE can report CLI. The uplink MAC-CE for CLI reporting may include one or more CLI value fields (6 bits) and one or more associated CSI-IM-ResourceSetIDs (6 bits) for CLI measurements. For each CSI-IM resource in the resource set, the UE can report one or more subband CLI values.

[0094] In some aspects, the base station can provide a joint MAC-CE for triggering SP CSI-IM resources and CLI reports. The MAC-CE that triggers SP CSI-IM resources can also trigger the victim UE to send a CLI / SI report associated with the resource set of the CSI-IM to the base station. For example, a MAC-CE that activates SP CSI-IM resources can trigger an SPCLI report based on the activated SP CSI-IM resource. The CLI report can be sent via PUCCH (L1 report) or via UL MAC-CE (L2 report). As another example, a MAC-CE that deactivates SP CSI-IM can trigger a CLI report using a UL MAC-CE. In this case, the UE can report an average CLI.

[0095] In some aspects, the base station can instruct the UE to report the most recent CLI measurement or the average of CLI measurements. That is, when RRC is configured, the base station can define a field in the CLI report (e.g., `timeRestrictionForInterferenceMeasurements`) to indicate whether the UE can report the most recent CLI measurement or the average (filtered) CLI over multiple measurement times when SP / PCSI-IM resources are configured. For example, if the defined field is configured (e.g., `timeRestrictionForInterferenceMeasurements = configured`), the UE can report the most recent CLI measurement. As another example, if the defined field is not configured (e.g., `timeRestrictionForInterferenceMeasurements = notconfigured`), the UE can report the average CLI.

[0096] In some aspects, the UE can indicate to the base station whether it has capabilities related to the activation of SP CLI reporting and SP CLI reporting. UE capabilities related to SP CLI reporting may include the ability to support a new MAC-CE (e.g., MAC-CE 1010) for configuring SRS at maximum power, the ability to support a new MAC-CE solely for triggering SP CSI-IM, the ability to use different QCL-Ds for SP CSI-IM measurement timing, the ability to support a new MAC-CE for triggering SP SRS and SP CSI-IM, the ability to support L2 CLI reporting, the ability to support a joint MAC-CE for triggering SP CSI-IM and CLI reporting, and the ability to support CLI reciprocity methods. The UE can indicate these UE capabilities related to SP CLI reporting when configuring RRC.

[0097] Figure 11The illustration shows CLI reciprocity between two UEs. The CLI measured by the victim UE can be a function of transmission power and coupling loss (CL). If the CL is known, the UE and the base station can estimate the CLI for different Tx powers. 1110 shows that base station 1102 can configure UE 111104 to have SRS or PUSCH transmissions on multiple time slots to base station 1102. Base station 1102 can configure UE 21106 with SP / PCSI-IM resources to measure CLI 1108 based on SRS or PUSCH transmissions on these time slots. Base station 1102 can inform victim UE 21106 of the average transmission power of UE 111104 at the CLI measurement time. Victim UE 21106 can estimate the average CL from the measurement of CLI 1108 and the average transmission power of aggressor UE 11104. Victim UE 21106 can report the average CL and / or CLI measurement to base station 1102. Base station 1102 can use the estimated average CL reported from UE1104 to estimate the CLI in the opposite direction from UE21106 to UE11104. 1110 illustrates that base station 1102 can check CLI reciprocity by configuring UE11104 to estimate and report CL based on the CLI 1112 with UE21106. Base station 1102 can check CLI reciprocity by comparing the estimated CL reported from UE21106 and the estimated CL reported from UE11104.

[0098] Figure 12 A wireless communication call flowchart 1200 is illustrated. Call flowchart 120 may include UE 1202 (e.g., UE 21106), base station 1204 (e.g., base station 1102), and intruder UE 1206 (e.g., UE 11104). Base station 1204 may configure SP resources for UE 1202 to perform CLI measurements, and UE 1202 may report a CLI report including CLI values ​​or measured CLI components indicating interference signals received from the SP resources.

[0099] At 1208, base station 1204 may send an RRC message including a CLI report configuration indicating that when the first MAC-CE configures UE 1202 with P or SP CSI-IM resources, UE 1202 reports the most recent CLI measurement or one of the filtered CLI values ​​across all CLI measurements in the CLI report. That is, base station 1204 may instruct UE 1202 to report the most recent CLI measurement or the average of the CLI measurements. At 1209, UE 1202 may indicate whether it has the capability associated with the activation of SP CLI reporting. The indications at 1208 and 1209 may be RRC messages transmitted during the configuration of the RRC connection between UE 1202 and base station 1204.

[0100] At 1210, base station 1204 can use SP CSI-IM resources to configure UE 1202 for CLI and / or SI measurements. UE 1202 can receive configurations for at least one SP CLI or SI measurement from base station 1204. In one aspect, the configuration from base station 1204 may include a set of configurations for at least one SP CLI or SI measurement. Base station 1204 can activate (or select) at least one configuration from the set of configurations for at least one SP CLI or SI measurement. Base station 1204 can transmit this configuration via an RRC message sent from base station 1204 to UE 1202.

[0101] At 1210', base station 1204 can also configure the aggressor UE 1206 using SP SRS resources. In one aspect, the configuration from base station 1204 may include a configuration set measured by at least one SP CLI or SI. Base station 1204 can activate (or select) at least one configuration from the configuration set measured by at least one SP CLI or SI. Base station 1204 can transmit this configuration via an RRC message sent from base station 1204 to the aggressor UE 1206.

[0102] At 1212, base station 1204 can send a MAC-CE to UE 1202 to activate the SP resources configured at 1210 for CLI and / or SI measurements. UE 1202 can receive the MAC-CE from base station 1204 activating the SP resources configured at 1210 for CLI and / or SI measurements. That is, base station 1204 can configure at least one set of configurations for SP CLI or SI measurements at 1210, and activate (or select) at least one configuration from at least one set of settings for SP CLI or SI measurements. Base station 1204 can send a MAC-CE activating SP CSI-IM resources to also trigger a CLI report. For example, the MAC-CE activating SP CSI-IM resources can also trigger an SP CLI report based on the triggered SP CSI-IM resources.

[0103] At 1212', base station 1204 can also send a MAC-CE to the aggressor UE 1206 to activate the SP SRS resource configured at 1210'. The aggressor UE 1206 can receive a MAC-CE from base station 1204 activating the SP resource configured at 1210 for CLI and / or SI measurements. That is, base station 1204 can configure at least one set of configurations for SP CLI or SI measurements at 1210, and activate (or select) at least one configuration from at least one set of configurations for SP CLI or SI measurements. Base station 1204 can send a MAC-CE activating the SP CSI-IM resource to also trigger a CLI report. For example, the MAC-CE activating the SP CSI-IM resource can also trigger an SP CLI report based on the triggered SP CSI-IM resource.

[0104] At 1214, UE 1202 can perform CLI and / or SI measurement activities in the configured SP resources activated by MAC-CE. That is, UE 1202 can measure the CLI and SI components reported by CLI through interference (e.g., CLI components) from uplink transmissions from intruder UE 1206 or interference (e.g., SI components) from uplink transmissions from UE 1202.

[0105] At 1216, base station 1204 can send a MAC-CE to deactivate the configured SP resource activated at 1212. UE 1202 can receive the MAC-CE to deactivate the SP resource, where the second MAC-CE triggers a CLI report. UE 1202 can receive the MAC-CE to deactivate the configured SP resource, stop performing CLI and / or SI measurements in the SP SRS resource, and report a CLI report.

[0106] At 1218, base station 1204 can configure the aggressor UE 1206 to have SRS or PUSCH transmissions on multiple timeslots to base station 1204. At 1220, base station 1204 can notify UE 1202 of the average transmission power of the aggressor UE 1206 during CLI measurement. UE 1202 receives the average transmission power of at least one interference signal from the aggressor UE 1206 from base station 1204. That is, base station 1204 can notify UE 1202 of the average transmission power of the aggressor UE 1206 during CLI measurement.

[0107] At 1222, UE 1202 can estimate the average CL with aggressor UE 1206 based on at least one CLI component measured in the SP resource and the average transmission power received. That is, UE 1202 can estimate the average CL from the CLI measured at 1214 and / or the average transmission power of aggressor UE 1206 received at 1220.

[0108] At 1226, UE 1202 can report a CLI report or an SI report, which includes a CLI component indicating a CLI value or measurement, or an SI component indicating a CLI value or measurement, from interference signals received in SP resources activated by MAC-CE. Base station 1204 can receive a CLI report or an SI report, which includes a CLI component indicating a CLI value or measurement, or an SI component indicating a CLI value or measurement, from interference signals received in SP resources activated by MAC-CE. The CLI report or SI report can be sent to base station 1204 via uplink MAC-CE. The CLI report or SI report can be sent in response to triggering events, including interference measured at 1214 exceeding a certain threshold, a change in CLI measured at 1214 due to a certain factor when a timer configured at 1208 expires, a periodic timer configured at 1208, and / or the deactivation of the SP CSI-IM resource set used for CLI measurements at 1216. In addition, the CLI report may include the average CL based on CLI measurements and the average transmission power estimate of the aggressor UE 1206 received at 1220. The CLI report and the estimated average CL may be sent at the same MAC-CE timing or at different MAC-CE timings.

[0109] At 1228, base station 1204 can estimate the CLI at the aggressor UE 1206 from UE 1202 based on the average CL estimated at 1214 and received from UE 1202 at 1226. That is, base station 1204 can use the estimated average CL reported from the aggressor UE 1206 to estimate the CLI in the opposite direction from UE 1202 to the aggressor UE 1206.

[0110] At 1230, base station 1204 can receive CLI reports, including an estimated CL based on interference with UE 1202. At 1232, base station 1204 can check CLI reciprocity between UE 1202 and aggressor UE 1206 based on the estimated CL reported from UE 1202 and aggressor UE 1206. That is, base station 1204 can check CLI reciprocity by comparing the estimated CL reported from UE 1202 at 1226 and the estimated CL reported from aggressor UE 1206 at 1230.

[0111] Figure 13 This is a flowchart 1300 of a wireless communication method. This method can be performed by a UE (e.g., UE 104; device 1402). A base station can configure SP resources for the UE to perform CLI measurements, and the UE can report a CLI report including CLI values ​​or measured CLI components indicating interference signals received from the SP resources.

[0112] At 1302, the UE can receive an indication from the base station to report the most recent CLI measurement or the average (or filtered) of CLI measurements during RRC configuration (e.g., as at 1208). This indication can be an RRC message transmitted during the configuration of the RRC connection between the UE and the base station. For example, at 1208, the UE 1202 can receive an indication from the base station 1204 regarding whether to report the most recent CLI measurement or the average of CLI measurements. Furthermore, 1302 can be performed by the CLI reporting component 1444.

[0113] At 1303, the UE may indicate whether it has the capability related to the activation of SP CLI and / or SI reports and SP CLI and / or SI reports (e.g., as at 1209). The UE may indicate whether it supports one or more of the following: MAC-CE for activating SRS for CLI or SI measurements with maximum transmission power; MAC-CE for activating SPCSI-IM for CLI and / or SI measurements; using different QCL D for SP SI-IM measurement timing; MAC-CE for activating SPCSI-IM and / or SP SRS resources for CLI and / or SI measurements; Layer 2 (L2) CLI reporting; a combined MAC-CE for triggering SP CSI-IM and CLI reports; or CLI reciprocity. This indication may be an RRC message transmitted during the configuration of the RRC connection between the UE and the base station. For example, at 1209, UE 1202 may send an indication to base station 1204 regarding whether UE 1202 has the capability related to the activation of SP CLI and SPCLI reports. In addition, 1316 can be executed by CLI reporting component 1444.

[0114] At 1304, the UE can receive configurations for one or more SP CSI-IM resources for CLI and / or SI measurements from the base station (e.g., as at 1210). In one aspect, the configuration from base station 1204 may include a configuration set for at least one SP CLI or SI measurement. Base station 1204 can activate (or select) at least one configuration from the configuration set for at least one SP CLI or SI measurement. Base station 1204 can transmit this configuration via an RRC message sent from base station 1204 to UE 1202. For example, at 1210, UE 1202 can receive configurations for at least one SP CLI or SI measurement from base station 1204. Furthermore, 1304 can be performed by CSI-IM resource management component 1440.

[0115] At 1306, the UE can receive from the base station a MAC-CE activating one or more SP resources (e.g., as at 1212) for CLI and / or SI measurements configured at 1304. That is, the base station can configure at least one set of configurations for SP CLI or SI measurements and activate (or select) at least one configuration from the configuration set for at least one SP CLI or SI measurement. The base station can send a MAC-CE activating an SP CSI-IM resource to also trigger a CLI report. For example, a MAC-CE activating an SP CSI-IM resource can also trigger an SP CLI report based on the triggered SP CSI-IM resource. Activating a MAC-CE can also indicate the transmission power of the SP SRS resource used for SP SI measurements. MAC-CE activating a CSI-IM resource can be separate from the activation / deactivation of the CSI-RS resource. Activating a MAC-CE can also activate CLI and / or SI reports. CLI and / or SI reports activated by a MAC-CE can be sent via PUCCH or an uplink MAC-CE. For example, at 1212, UE 1202 can receive a MAC-CE from base station 1204, which activates SP resources as configured for CLI and / or SI measurements. Furthermore, 1306 can be performed by CSI-IM resource management component 1440.

[0116] At 1308, the UE can perform CLI and / or SI measurement activities in one or more SP resources configured and activated by MAC-CE (e.g., as at 1214). That is, the UE can measure the CLI and SI components reported by CLI through interference from uplink transmissions from an aggressor UE (e.g., CLI components) or interference from uplink transmissions from the UE itself (e.g., SI components). For example, at 1214, UE 1202 can perform CLI and / or SI measurement activities in SP resources configured and activated by MAC-CE. Furthermore, 1308 can be performed by the CLI reporting component 1444.

[0117] At 1310, the UE may receive a MAC-CE that deactivates one or more SP resources configured at 1306 (e.g., as at 1216). The UE may receive the MAC-CE to deactivate the configured SP resources, stop performing CLI and / or SI measurements in the SP SRS resources, and report a CLI report. The deactivation MAC-CE may also activate CLI and / or SI reports. CLI and / or SI reports activated by the deactivation MAC-CE may be transmitted via an uplink MAC-CE, and the CLI and / or SI reports may include an average CLI. For example, at 1216, UE 1202 may receive a MAC-CE to deactivate SP resources, where a second MAC-CE triggers a CLI report. Furthermore, 1310 may be performed by the CSI-IM resource management component 1440.

[0118] At 1312, the UE can receive the average transmission power of at least one interference signal from the aggressor UE from base station 1204. That is, the UE can receive the average transmission power of the aggressor UE at a CLI measurement time (e.g., at 1220). For example, at 1220, UE 1202 can receive the average transmission power of at least one interference signal from the aggressor UE 1206 from base station 1204. Furthermore, 1312 can be performed by CLI reporting component 1444.

[0119] At 1314, the UE can estimate the average CL with the aggressor UE 1206 based on at least one CLI component measured in the SP resource and the average received transmission power. That is, the UE can estimate the average CL from the CLI measured at 1308 and the average transmission power of the aggressor UE received at 1312 (e.g., as at 1222). For example, at 1222, UE 1202 can estimate the average CL with the aggressor UE 1206 based on at least one CLI component measured in the SP resource and the average received transmission power. Furthermore, 1314 can be performed by the interference measurement component 1442.

[0120] At 1318, the UE can report a CLI report, which includes CLI values ​​or measured CLI components indicating interference signals received from SP resources activated by MAC-CE (e.g., as at 1226). CLI reports can be sent via uplink MAC-CE. CLI reports can be sent in response to triggering events, including interference measured at 1308 exceeding a certain threshold, a change in CLI measured at 1308 due to a factor when a timer configured at 1302 expires, a periodic timer configured at 1302, and / or deactivation of the SP CSI-IM resource set received at 1310 for CLI measurements. Furthermore, the CLI report can include the average CL based on CLI measurements and an estimate of the average transmission power of the aggressor UE received at 1312. CLI reports and the estimated average CL can be sent at different MAC-CE times. For example, at 1226, UE 1202 can report a CLI report, which includes CLI values ​​or measured CLI components indicating interference signals received in SP resources activated by MAC-CE. Furthermore, 1318 can be performed by CLI reporting component 1444.

[0121] Figure 14 This is a flowchart 1400 of a wireless communication method. This method can be performed by a UE (e.g., UE 104; device 1502). A base station can configure SP resources for the UE to perform CLI measurements, and the UE can report a CLI report including CLI values ​​or measured CLI components indicating interference signals received from the SP resources.

[0122] At 1404, the UE can receive configurations for one or more SP CSI-IM resources for CLI and / or SI measurements from the base station (e.g., as at 1210). In one aspect, the configuration from base station 1204 may include a configuration set for at least one SP CLI or SI measurement. Base station 1204 can activate (or select) at least one configuration from the configuration set for at least one SP CLI or SI measurement. Base station 1204 can transmit this configuration via an RRC message sent from base station 1204 to UE 1202. For example, at 1210, UE 1202 can receive configurations for at least one SP CLI or SI measurement from base station 1204. Furthermore, 1404 can be performed by CSI-IM resource management component 1440.

[0123] At 1406, the UE can receive a MAC-CE from the base station that activates one or more SP resources (e.g., as at 1212) for CLI and / or SI measurements configured at 1404. That is, the base station can configure at least one set of configurations for SPCLI or SI measurements and activate (or select) at least one configuration in at least one set of configurations for SP CLI or SI measurements. The base station can send a MAC-CE activating SP CSI-IM resources to also trigger a CLI report. For example, a MAC-CE activating SPCSI-IM resources can also trigger an SP CLI report based on the triggered SP CSI-IM resources. Activating the MAC-CE can also indicate the transmission power of SP SRS resources used for SP SI measurements. Activating the MAC-CE for CSI-IM resources can be separate from the activation / deactivation of CSI-RS resources. Activating the MAC-CE can also activate CLI and / or SI reports. CLI and / or SI reports activated by the MAC-CE can be sent via PUCCH or uplink MAC-CE. For example, at 1212, UE 1202 can receive a MAC-CE from base station 1204, which activates SP resources as configured for CLI and / or SI measurements. Furthermore, 1406 can be performed by CSI-IM resource management component 1440.

[0124] At 1408, the UE can perform CLI and / or SI measurement activities in one or more SP resources configured and activated by MAC-CE (e.g., as at 1214). That is, the UE can measure the CLI and SI components reported by CLI through interference from uplink transmissions from an aggressor UE (e.g., CLI components) or interference from uplink transmissions from the UE itself (e.g., SI components). For example, at 1214, UE 1202 can perform CLI and / or SI measurement activities in SP resources configured and activated by MAC-CE. Furthermore, 1408 can be performed by the CLI reporting component 1444.

[0125] At 1418, the UE can report a CLI report, which includes CLI values ​​or measured CLI components indicating interference signals received in SP resources activated by MAC-CE (e.g., as at 1226). CLI reports can be sent via uplink MAC-CE. CLI reports can be sent in response to triggering events, including interference measured at 1408 exceeding a certain threshold, a change in CLI measured at 1408 due to a factor when a timer configured at 1402 expires, a periodic timer configured at 1402, and / or deactivation of the SP CSI-IM resource set received at 1410 for CLI measurements. Furthermore, the CLI report can include the average CL based on CLI measurements and an estimate of the average transmission power of the aggressor UE received at 1412. CLI reports and the estimated average CL can be sent at different MAC-CE times. For example, at 1226, UE 1202 can report a CLI report, which includes CLI values ​​or measured CLI components indicating interference signals received in SP resources activated by MAC-CE. Furthermore, 1418 can be performed by CLI reporting component 1444.

[0126] Figure 15This is a schematic diagram 1500 illustrating an example of a hardware implementation of device 1502. Device 1502 may be a UE, a component of a UE, or may implement UE functionality. In some aspects, device 1502 may include a cellular baseband processor 1504 (also referred to as a modem) coupled to a cellular RF transceiver 1522. In some aspects, device 1502 may also include one or more Subscriber Identity Module (SIM) cards 1520, an application processor 1506 coupled to a Secure Digital Card (SD) card 1508 and a screen 1510, a Bluetooth module 1512, a Wireless Local Area Network (WLAN) module 1514, a Global Positioning System (GPS) module 1516, or a power supply 1518. Cellular baseband processor 1504 communicates with UE 104 and / or base station 102 / 180 via cellular RF transceiver 1522. Cellular baseband processor 1504 may include computer-readable media / memory. The computer-readable media / memory may be non-transitory. Cellular baseband processor 1504 is responsible for general processing, including executing software stored on a computer-readable medium / memory. When the software is executed by cellular baseband processor 1504, it causes cellular baseband processor 1504 to perform the various functions described above. The computer-readable medium / memory can also be used to store data manipulated by cellular baseband processor 1504 during software execution. Cellular baseband processor 1504 also includes receiving component 1530, communication manager 1532, and transmission component 1534. Communication manager 1532 includes one or more of the components shown. Components within communication manager 1532 can be stored in computer-readable medium / memory and / or configured as hardware within cellular baseband processor 1504. Cellular baseband processor 1504 can be a component of UE 350 and can include memory 360 and / or at least one of TX processor 368, RX processor 356, and controller / processor 359. In one configuration, device 1502 can be a modem chip and only includes baseband processor 1504, while in another configuration, device 1502 can be the entire UE (e.g., see...). Figure 3 (350) and includes an additional module of device 1502.

[0127] Communication manager 1532 includes a CSI-IM resource management component 1540, which is configured to receive configurations for one or more SP CSI-IM resources for SP CLI and / or SI measurements, receive from a base station a MAC-CE activating one or more SP resources for CLI and / or SI measurements, and receive a MAC-CE deactivating one or more SP resources, for example, as described in conjunction with 1304, 1306, 1310, 1404, and 1406. Communication manager 1532 also includes an interference measurement component 1542, which is configured to estimate the average CL from the measured CLI and the average transmission power of the aggressor UE, for example, as described in conjunction with 1314. The communication manager 1532 also includes a CLI reporting component 1544 configured to receive an indication from the base station to report the most recent CLI measurement or the average (or filtered) of CLI measurements during RRC configuration, to indicate whether the UE has the capability associated with the activation of SPCLI and / or SI reports and SP CLI and / or SI reports, to perform CLI and / or SI measurement activities in one or more SP resources configured by MAC-CE, to receive the average transmission power of the aggressor UE at the CLI measurement time, and to report a CLI report including CLI values ​​or measured CLI components indicating interference signals received from MAC-CE activated SP resources, for example, as described in conjunction with 1302, 1303, 1308, 1312, 1318, 1408, and 1418.

[0128] The device may include execution Figure 12 , 13 And additional components for each block of the algorithm in flowchart 14. Thus, Figure 12 , 13 Each block in the flowchart of section 14 can be executed by a component, and the apparatus can include one or more of these components. These components can be one or more hardware components specifically configured to execute the process / algorithm, implemented by a processor configured to execute the process or algorithm, stored in a computer-readable medium for processor implementation, or some combination thereof.

[0129] As shown in the figure, apparatus 1502 may include various components configured for various functions. In one configuration, apparatus 1502, particularly cellular baseband processor 1504, includes components for receiving configurations of at least one SP resource for CLI or SI measurements from a base station, components for receiving from the base station a first MAC-CE activating the SP resource configured for CLI or SI measurements, and components for performing CLI or SI measurement activities in the at least one configured SP resource activated by the MAC-CE. Apparatus 1502 includes components for receiving an RRC message including a CLI reporting configuration instructing the UE to report a recent CLI measurement or one of filtered CLI values ​​on all CLI measurements in the CLI report when the first MAC-CE configures the UE with P or SP CSI-IM resources, and components for reporting a CLI report to the base station, the CLI report including at least one CLI component measured from at least one interference signal received from the SP resource activated by the MAC-CE. Apparatus 1502 includes components for receiving a second MAC-CE to deactivate SP resources, wherein the second MAC-CE triggers a CLI report, and components for sending a CLI report to a base station, the CLI report including the average CLI in the uplink MAC-CE. Apparatus 1502 includes components for receiving the average transmission power of at least one interference signal from an aggressor UE from a base station, and components for estimating the average CLI with respect to the aggressor UE based on at least one CLI component measured in the SP resources and the received average transmission power. Apparatus 1502 includes components for instructing a base station during RRC configuration whether a UE supports at least one of the following: activating a MAC-CE for SRS used for CLI or SI measurements with pre-configured transmission power; activating a MAC-CE for SPCSI-IM used for CLI and SI measurements; using different QCL D for SP CSI-IM measurement timing; activating a MAC-CE for SPSRS and SP CSI-IM resources used for CLI or SI measurements; L2 CLI reporting; a combined MAC-CE triggering SP CSI-IM and CLI reporting; or calculating and reporting a CL with an aggressor UE based on the average transmission power of the interfering signal. The components may be one or more components of apparatus 1502 configured to perform the functions described herein. As described above, apparatus 1502 may include a TX processor 368, an RX processor 356, and a controller / processor 359. Thus, in one configuration, the components may be a TX processor 368, an RX processor 356, and a controller / processor 359 configured to perform the functions described herein.

[0130] Figure 16This is a flowchart 1600 of a wireless communication method. This method can be performed by a base station (e.g., base station 102 / 180; device 1802). The base station can configure SP resources for the UE to perform CLI measurements, and the base station can receive CLI reports from the UE, which include CLI values ​​or measured CLI components indicating interference signals received from the SP resources.

[0131] At 1602, when the first MAC-CE configures the UE with P or SP CSI-IM resources, the base station can send an RRC message including CLI reporting configuration, which instructs the UE to report a recent CLI measurement or one of a filtered CLI value across all CLI measurements in the CLI report. That is, the base station can instruct the UE to report a recent CLI measurement or an average (or filtered) CLI measurement during RRC configuration (e.g., as at 1208). This instruction can be sent to the UE as an RRC message. For example, at 1208, base station 1204 can send an RRC message including CLI reporting configuration, which instructs UE 1202 to report a recent CLI measurement or one of a filtered CLI value across all CLI measurements in the CLI report when the first MAC-CE configures the UE 1202 with P or SP CSI-IM resources. Furthermore, 1602 can be performed by CLI component 1842.

[0132] At 1603, the base station can receive from the UE an indication of whether the UE has the capability related to the activation of SP CLI reports and SP CLI reports. That is, the base station can receive from the UE an indication of whether the UE has the capability related to the activation of SP CLI and / or SI reports and SP CLI and / or SI reports (e.g., as at 1209). The UE can indicate whether it supports one or more of the following: activating MAC-CE for SRS for CLI or SI measurements with maximum transmission power; activating MAC-CE for SP CSI-IM for CLI and / or SI measurements; using different QCL D for SP SI-IM measurement timing; activating MAC-CE for SP CSI-IM and / or SP SRS resources for CLI and / or SI measurements; L2 CLI reporting; triggering a joint MAC-CE or CLI reciprocity for SP CSI-IM and CLI reports. This indication can be received from the UE as an RRC message. For example, at 1209, base station 1204 can receive from UE 1202 an indication of whether UE 1202 has the capability related to the activation of SP CLI reports and SP CLI reports. In addition, 1614 can be executed by CLI component 1842.

[0133] At 1604, the base station can configure one or more SP CSI-IM resources for CLI and / or SI measurements for the UE (e.g., as at 1210). The base station can also configure an aggressor UE with SP SRS resources (e.g., as at 1210'). The base station can activate (or select) at least one configuration from at least one configuration set for SP CLI or SI measurements. The base station can transmit this configuration via an RRC message sent from the base station to the UE. For example, at 1210, base station 1204 can configure SP CSI-IM resources for CLI and / or SI measurements for UE 1202. Furthermore, 1604 can be performed by CSI-IM resource management component 1840.

That is, the base station can configure at least one set of configurations for SPCLI or SI measurements and activate (or select) at least one configuration in at least one set of configurations for SP CLI or SI measurements. The base station can send a MAC-CE to activate the SP CSI-IM resource to also trigger a CLI report. For example, a MAC-CE to activate the SPCSI-IM resource can also trigger an SP CLI report based on the triggered SP CSI-IM resource. Furthermore, the base station can configure at least one set of configurations for SP CLI or SI measurements and activate (or select) at least one configuration in at least one set of configurations for SP CLI or SI measurements. The base station can send a MAC-CE to activate the SP CSI-IM resource to also trigger a CLI report.

CLI and / or SI reports activated by the deactivation MAC-CE can be received via an uplink MAC-CE, and the CLI and / or SI reports can include averaged CLI. The UE can receive the MAC-CE to deactivate the configured SP resources, stop performing CLI and / or SI measurements in the SP SRS resources, and report a CLI report. For example, at 1216, base station 1204 can send a MAC-CE to deactivate the configured SP resources activated at 1212.

Furthermore, the CLI report can include the average CL based on CLI measurements and the average transmission power estimate of the aggressor UE received at 1612. The CLI report and the estimated average CL can be received at different MAC-CE times. For example, at 1226, base station 1204 can receive a CLI report, which includes CLI values ​​or measured CLI components indicating interference signals received from SP resources activated by MAC-CE, 1616 of which can be performed by CLI component 1842.

[0139] At 1618, the base station can estimate the CLI at the aggressor UE from the UE based on the average CL estimated and received from the UE. That is, the base station can estimate the CLI at the aggressor UE from the UE based on the average CL estimated at 1616 and received from the UE (e.g., as at 1228). For example, at 1228, base station 1204 can estimate the CLI at the aggressor UE 1206 from UE 1202 based on the average CL estimated at 1214 and received from UE 1202 at 1226.

For example, at 1230, base station 1204 may receive a CLI report including an estimated CL based on interference with UE 1202. Furthermore, 1620 may be performed by CLI component 1842.

[0141] At 1622, the base station can check CLI reciprocity between the UE and the aggressor UE based on the estimated CL reported from the UE and the aggressor UE (e.g., as at 1232). That is, the base station can check CLI reciprocity by comparing the estimated CL reported from the UE at 1616 with the estimated CL reported from the aggressor UE 1206 at 1620. For example, at 1232, base station 1204 can check CLI reciprocity between UE 1202 and the aggressor UE 1204 based on the estimated CL reported from UE 1202 and the aggressor UE 1206. Furthermore, 1622 can be performed by CLI component 1842.

That is, the base station can receive a CLI report from the UE, which includes a CLI value or measured CLI component indicating interference signals received from SP resources activated by MAC-CE (e.g., as at 1226). The CLI report can be received via uplink MAC-CE.
