Description

METHOD AND DEVICE FOR RECEIVING AND TRANSMITTING INFORMATION

[0001] The application relates to the technical field of wireless communication, and more specifically, relates to a method and device for receiving and transmitting information.

[0002] In order to meet the increasing demand for wireless data communication services since the deployment of 4G communication systems, efforts have been made to develop improved 5G or pre-5G communication systems. Therefore, 5G or pre-5G communication systems are also called “Beyond 4G networks” or “Post-LTE systems”.

[0003] In order to achieve a higher data rate, 5G communication systems are implemented in higher frequency (millimeter, mmWave) bands, e.g., 60 GHz bands. In order to reduce propagation loss of radio waves and increase a transmission distance, technologies such as beamforming, massive multiple-input multiple-output (MIMO), full-dimensional MIMO (FD-MIMO), array antenna, analog beamforming and large-scale antenna are discussed in 5G communication systems.

[0004] In addition, in 5G communication systems, developments of system network improvement are underway based on advanced small cell, cloud radio access network (RAN), ultra-dense network, device-to-device (D2D) communication, wireless backhaul, mobile network, cooperative communication, coordinated multi-points (CoMP), reception-end interference cancellation, etc.

[0005] In 5G systems, hybrid FSK and QAM modulation (FQAM) and sliding window superposition coding (SWSC) as advanced coding modulation (ACM), and filter bank multicarrier (FBMC), non-orthogonal multiple access (NOMA) and sparse code multiple access (SCMA) as advanced access technologies have been developed.

[0006] The transmission from a base station to a user equipment (UE) is called downlink, and the transmission from the UE to the base station is called uplink.

[0007] 5th generation (5G) mobile communication technologies define broad frequency bands such that high transmission rates and new services are possible, and can be implemented not only in “Sub 6GHz” bands such as 3.5GHz, but also in “Above 6GHz” bands referred to as mmWave including 28GHz and 39GHz. In addition, it has been considered to implement 6G mobile communication technologies (referred to as Beyond 5G systems) in terahertz bands (for example, 95GHz to 3THz bands) in order to accomplish transmission rates fifty times faster than 5G mobile communication technologies and ultra-low latencies one-tenth of 5G mobile communication technologies.

[0008] At the beginning of the development of 5G mobile communication technologies, in order to support services and to satisfy performance requirements in connection with enhanced Mobile BroadBand (eMBB), Ultra Reliable Low Latency Communications (URLLC), and massive Machine-Type Communications (mMTC), there has been ongoing standardization regarding beamforming and massive MIMO for mitigating radio-wave path loss and increasing radio-wave transmission distances in mmWave, supporting numerologies (for example, operating multiple subcarrier spacings) for efficiently utilizing mmWave resources and dynamic operation of slot formats, initial access technologies for supporting multi-beam transmission and broadbands, definition and operation of BWP (BandWidth Part), new channel coding methods such as a LDPC (Low Density Parity Check) code for large amount of data transmission and a polar code for highly reliable transmission of control information, L2 pre-processing, and network slicing for providing a dedicated network specialized to a specific service.

[0009] Currently, there are ongoing discussions regarding improvement and performance enhancement of initial 5G mobile communication technologies in view of services to be supported by 5G mobile communication technologies, and there has been physical layer standardization regarding technologies such as V2X (Vehicle-to-everything) for aiding driving determination by autonomous vehicles based on information regarding positions and states of vehicles transmitted by the vehicles and for enhancing user convenience, NR-U (New Radio Unlicensed) aimed at system operations conforming to various regulation-related requirements in unlicensed bands, NR UE Power Saving, Non-Terrestrial Network (NTN) which is UE-satellite direct communication for providing coverage in an area in which communication with terrestrial networks is unavailable, and positioning.

[0010] Moreover, there has been ongoing standardization in air interface architecture / protocol regarding technologies such as Industrial Internet of Things (IIoT) for supporting new services through interworking and convergence with other industries, IAB (Integrated Access and Backhaul) for providing a node for network service area expansion by supporting a wireless backhaul link and an access link in an integrated manner, mobility enhancement including conditional handover and DAPS (Dual Active Protocol Stack) handover, and two-step random access for simplifying random access procedures (2-step RACH for NR). There also has been ongoing standardization in system architecture / service regarding a 5G baseline architecture (for example, service based architecture or service based interface) for combining Network Functions Virtualization (NFV) and Software-Defined Networking (SDN) technologies, and Mobile Edge Computing (MEC) for receiving services based on UE positions.

[0011] As 5G mobile communication systems are commercialized, connected devices that have been exponentially increasing will be connected to communication networks, and it is accordingly expected that enhanced functions and performances of 5G mobile communication systems and integrated operations of connected devices will be necessary. To this end, new research is scheduled in connection with eXtended Reality (XR) for efficiently supporting AR (Augmented Reality), VR (Virtual Reality), MR (Mixed Reality) and the like, 5G performance improvement and complexity reduction by utilizing Artificial Intelligence (AI) and Machine Learning (ML), AI service support, metaverse service support, and drone communication.

[0012] Furthermore, such development of 5G mobile communication systems will serve as a basis for developing not only new waveforms for providing coverage in terahertz bands of 6G mobile communication technologies, multi-antenna transmission technologies such as Full Dimensional MIMO (FD-MIMO), array antennas and large-scale antennas, metamaterial-based lenses and antennas for improving coverage of terahertz band signals, high-dimensional space multiplexing technology using OAM (Orbital Angular Momentum), and RIS (Reconfigurable Intelligent Surface), but also full-duplex technology for increasing frequency efficiency of 6G mobile communication technologies and improving system networks, AI-based communication technology for implementing system optimization by utilizing satellites and AI (Artificial Intelligence) from the design stage and internalizing end-to-end AI support functions, and next-generation distributed computing technology for implementing services at levels of complexity exceeding the limit of UE operation capability by utilizing ultra-high-performance communication and computing resources.

[0013] The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

[0014] The present disclosure may provide a method and device for receiving and transmitting information.

[0015] The technical objects to be achieved by various embodiments of the disclosure are not limited to the technical objects mentioned above, and other technical objects not mentioned may be considered by those skilled in the art from various embodiments of the disclosure to be described below.

[0016] In order to enhance the scheduling efficiency of the 5G wireless communication system, the base station needs to obtain channel state information (CSI) to schedule according to the CSI fed back by the terminal equipment. However, how to further enhance the performance of CSI reporting is a problem to be solved.

[0017] An aspect of the present disclosure provides a method performed by a user equipment (UE) in a wireless communication system, which includes receiving a channel state information (CSI) reporting configuration; reporting CSI based on the CSI reporting configuration, wherein the CSI reporting configuration includes at least one of a report quantity parameter, second information for indicating an Artificial Intelligence (AI)-enabled feature, third information for an AI-enabled feature related model, predicted beam identification (ID) related spatial information, predicted beam identification (ID) related time information, and first information for indicating the enabling or disabling of Layer 1-Reference Signal Received Power (L1-RSRP) reporting, and wherein the CSI includes at least one of a predicted beam identification (ID) and / or a predicted L1-RSRP.

[0018] In one example, when the CSI reporting configuration includes the spatial information, the CSI is for spatial domain downlink beam prediction; and / or when the CSI reporting configuration includes the time information, the CSI is for time domain downlink beam prediction; and / or when the CSI reporting configuration includes the report quantity parameter which is set to ‘cri-RSRP’ or ‘ssb-Index-RSRP’ and the CSI reporting configuration includes the time information, the CSI is for the time domain downlink beam prediction.

[0019] In one example, when the CSI reporting configuration includes the first information and the first information indicates that the predicted L1-RSRP is disabled, the CSI includes the predicted beam ID; or when the CSI reporting configuration does not include the first information, the CSI includes the predicted beam ID; or when the CSI reporting configuration includes the first information and the first information indicates that the predicted L1-RSRP is enabled, the CSI includes the predicted beam ID and the predicted L1-RSRP associated with the predicted beam ID.

[0020] In one example, reporting the predicted beam ID when the second information indicates that the AI-enabled feature is downlink beam prediction and the second information indicates that the CSI reporting configuration is CSI reporting based on model inference; or reporting the predicted beam ID and the predicted L1-RSRP corresponding to the predicted beam ID when the second information indicates that the AI-enabled feature is downlink beam prediction and L1-RSRP prediction and the second information indicates that the CSI reporting configuration is the CSI reporting based on model inference; or reporting the predicted beam ID when the second information indicates that the CSI reporting configuration is the CSI reporting based on model inference, and / or the third information indicates that an output of a model includes a beam ID; or reporting the predicted beam ID and the predicted L1-RSRP associated with the predicted beam ID when the second information indicates that the CSI reporting configuration is the CSI reporting based on model inference, and / or the third information indicates that the output of the model includes the beam ID and a L1-RSRP.

[0021] In one example, reporting the predicted beam ID when the second information indicates downlink beam prediction and / or the CSI reporting configuration is the CSI reporting based on model inference and the first information indicates that the predicted L1-RSRP is disabled; or reporting the predicted beam ID when the second information indicates downlink beam prediction and / or the CSI reporting configuration is the CSI reporting based on model inference and the first information is not included; or reporting the predicted beam ID and the predicted L1-RSRP associated with the predicted beam ID when the second information indicates downlink beam prediction and / or the CSI reporting configuration is the CSI reporting based on model inference and the first information indicates that the predicted L1-RSRP is enabled.

[0022] In one example, the predicted beam ID includes a predicted CSI reference signal (CSI-RS) resource indicator (CRI) or a synchronization signal / physical broadcast signal (SS / PBCH) block (SSB) resource indicator (SSBRI), and the CSI report includes: reporting the predicted CRI and the predicted L1-RSRP associated with the predicted CRI when the report quantity parameter is set to ‘cri-RSRP’, the first information indicates that the predicted L1-RSRP is enabled and the CSI reporting configuration includes the time information; or reporting the predicted CRI when the report quantity parameter is set to ‘cri-RSRP’, the first information indicates that the predicted L1-RSRP is disabled and the CSI reporting configuration includes the time information; or reporting the predicted CRI when the report quantity parameter is set to ‘cri-RSRP’ and the CSI reporting configuration does not include the first information but includes the time information; or reporting the predicted SSBRI and the predicted L1-RSRP associated with the predicted SSBRI when the report quantity parameter is set to ‘ssb-Index-RSRP’, the first information indicates that the predicted L1-RSRP is enabled and the CSI reporting configuration includes the time information; or reporting the predicted SSBRI when the report quantity parameter is set to ‘ssb-Index-RSRP’, the first information indicates that the predicted L1-RSRP is disabled and the CSI reporting configuration includes the time information; or reporting the predicted SSBRI when the report quantity parameter is set to ‘ssb-Index-RSRP’ and the CSI reporting configuration does not include the first information but includes the time information.

[0023] In one example, the predicted beam ID is associated with one or more time intervals determined based on the time information; or the predicted CRI is associated with one or more time intervals determined based on the time information; or the predicted SSBRI is associated with one or more time intervals determined based on the time information; or the predicted L1-RSRP is associated with one or more time intervals determined based on the time information.

[0024] In one example, a number of occupied channel state information processing units (CPUs) associated with the CSI reporting configuration is determined based on at least one of the followings: the report quantity parameter; the first information; the second information; the third information; the spatial information; the time information; a resource type of a resource set associated with the CSI reporting configuration; a number of resource set(s) associated with the CSI reporting configuration; a number of resources in the resource set associated with the CSI reporting configuration; UE capability.

[0025] In an example, the number of the occupied CPUs associated with the CSI reporting configuration is determined based on at least one of the second information, the third information and the UE capability when the CSI reporting configuration includes the second information and / or the third information.

[0026] In one example, the number of the occupied CPUs associated with the CSI reporting configuration is determined based on at least one of a beam ID set determined by the spatial information, the resource set associated with the CSI reporting configuration, and the UE capability when the CSI reporting configuration includes the spatial information, wherein the beam ID predicted based on the CSI reporting configuration is from the beam ID set.

[0027] In one example, the number of the occupied CPUs associated with the CSI reporting configuration is determined based on at least one of a number of the one or more time intervals determined by the time information, a number of the one or more measurement occasions determined by the time information, the number of resources in the resource set associated with the CSI reporting configuration, and the UE capability when the CSI reporting configuration includes the time information, wherein the beam ID predicted based on the CSI reporting configuration is associated with one or more time intervals determined by the time information.

[0028] In one example, the number of the occupied CPUs associated with the CSI reporting configuration is determined based on whether the predicted L1-RSRP is included in the CSI.

[0029] In one example, when the CSI is periodic or semi-persistent, symbols of the occupied CPUs associated with the CSI reporting configuration include: from the first symbol of the latest consecutive Y1 CSI-RS occasions no later than the CSI reference resources to the last symbol of the physical uplink shared channel (PUSCH) or the physical uplink control channel (PUCCH) carrying the CSI, where Y1≥ 1; or from the first symbol of the latest consecutive Y1 SSB occasions no later than the CSI reference resources to the last symbol of the PUSCH or PUCCH carrying the CSI report.

[0030] In one example, Y1 is determined based on the UE capability, or Y1 is indicated by the time information.

[0031] In one example, time for CSI calculation associated with the CSI reporting configuration is determined based on at least one of the followings: a preset value; the second information; the third information; the number of resource sets associated with the CSI reporting configuration; the number of resources in the resource set associated with the CSI reporting configuration; time separation between resources in the resource set associated with the CSI reporting configuration; the periodicity corresponding to the resources in the resource set associated with the CSI reporting configuration; the resource type of the resource set associated with the CSI reporting configuration; the resource types of the resources in the resource set associated with the CSI reporting configuration; the UE capability.

[0032] In one example, when the resource type of the resource set for channel measurement associated with the CSI reporting configuration is aperiodic, the time for CSI calculation associated with the CSI reporting configuration is determined based on at least one of the preset value, the time separation between the resources in the resource set associated with the CSI reporting configuration, and the number of the resources in the resource set associated with the CSI reporting configuration.

[0033] In one example, the time for CSI calculation associated with the CSI reporting configuration is determined based on at least one of the preset value, the second information, the third information and the UE capability.

[0034] In one example, when the resource type of the resource in the resource set associated with the CSI reporting configuration is periodic or semi-persistent, the resource and / or the CSI-RS port in the resource are counted Y2 times, where Y2≥0, and where the value of Y2 is predefined or indicated by the UE capability.

[0035] Another aspect of the present disclosure provides a method performed by a base station in a wireless communication system, which includes: transmitting a channel state information (CSI) reporting configuration; receiving CSI reported based on the CSI reporting configuration, wherein the CSI reporting configuration includes at least one of a report quantity parameter, second information for indicating an Artificial Intelligence (AI)-enabled feature, third information for an AI-enabled feature related model, spatial information, time information, and first information for indicating enabling or disabling of Layer 1- Reference Signal Received Power (L1-RSRP) reporting, and wherein the CSI includes at least one of a predicted beam identification (ID) and / or a predicted L1-RSRP.

[0054] Advantages and features of the present disclosure and ways to achieve them will become clear with reference to the embodiments described in detail below in conjunction with the accompanying drawings. However, the present disclosure is not limited to the embodiments set forth below, but can be realized in various forms. The following examples are provided only to fully disclose this disclosure and to inform those skilled in the art of its scope, and this disclosure is only limited by the scope of the appended claims. Throughout this specification, the same or similar reference numerals indicate the same or similar elements.

[0055] FIG. 1 illustrates an example wireless network 100 according to various embodiments of the present disclosure. The embodiment of the wireless network 100 shown in FIG. 1 is for illustration only. Other embodiments of the wireless network 100 can be used without departing from the scope of the present disclosure.

[0056] The wireless network 100 includes a gNodeB (gNB) 101, a gNB 102, and a gNB 103. gNB 101 communicates with gNB 102 and gNB 103. gNB 101 also communicates with at least one Internet Protocol (IP) network 130, such as the Internet, a private IP network, or other data networks.

[0057] Depending on a type of the network, other well-known terms such as “base station” or “access point” can be used instead of “gNodeB” or “gNB”. For convenience, the terms “gNodeB” and “gNB” are used in this patent document to refer to network infrastructure components that provide wireless access for remote terminals. And, depending on the type of the network, other well-known terms such as “mobile station”, “user station”, “remote terminal”, “wireless terminal” or “user apparatus” can be used instead of “user equipment” or “UE”. For convenience, the terms “user equipment” and “UE” are used in this patent document to refer to remote wireless devices that wirelessly access the gNB, no matter whether the UE is a mobile device (such as a mobile phone or a smart phone) or a fixed device (such as a desktop computer or a vending machine).

[0058] gNB 102 provides wireless broadband access to the network 130 for a first plurality of User Equipments (UEs) within a coverage area 120 of gNB 102. The first plurality of UEs include a UE 111, which may be located in a Small Business (SB); a UE 112, which may be located in an enterprise (E); a UE 113, which may be located in a WiFi Hotspot (HS); a UE 114, which may be located in a first residence (R); a UE 115, which may be located in a second residence (R); a UE 116, which may be a mobile device (M), such as a cellular phone, a wireless laptop computer, a wireless PDA, etc. GNB 103 provides wireless broadband access to network 130 for a second plurality of UEs within a coverage area 125 of gNB 103. The second plurality of UEs include a UE 115 and a UE 116. In some embodiments, one or more of gNBs 101-103 can communicate with each other and with UEs 111-116 using 5G, Long Term Evolution (LTE), LTE-A, WiMAX or other advanced wireless communication technologies.

[0059] The dashed lines show approximate ranges of the coverage areas 120 and 125, and the ranges are shown as approximate circles merely for illustration and explanation purposes. It should be clearly understood that the coverage areas associated with the gNBs, such as the coverage areas 120 and 125, may have other shapes, including irregular shapes, depending on Configurations of the gNBs and changes in the radio environment associated with natural obstacles and man-made obstacles.

[0060] As will be described in more detail below, one or more of gNB 101, gNB 102, and gNB 103 include a 2D antenna array as described in embodiments of the present disclosure. In some embodiments, one or more of gNB 101, gNB 102, and gNB 103 support codebook designs and structures for systems with 2D antenna arrays.

[0061] Although FIG. 1 illustrates an example of the wireless network 100, various changes can be made to FIG. 1. The wireless network 100 can include any number of gNBs and any number of UEs in any suitable arrangement, for example. Furthermore, gNB 101 can directly communicate with any number of UEs and provide wireless broadband access to the network 130 for those UEs. Similarly, each gNB 102-103 can directly communicate with the network 130 and provide direct wireless broadband access to the network 130 for the UEs. In addition, gNB 101, 102 and / or 103 can provide access to other or additional external networks, such as external telephone networks or other types of data networks.

[0062] FIGs. 2a and 2b illustrate example wireless transmission and reception paths according to the present disclosure. In the following description, the transmission path 200 can be described as being implemented in a gNB, such as gNB 102, and the reception path 250 can be described as being implemented in a UE, such as UE 116. However, it should be understood that the reception path 250 can be implemented in a gNB and the transmission path 200 can be implemented in a UE. In some embodiments, the reception path 250 is configured to support codebook designs and structures for systems with 2D antenna arrays as described in embodiments of the present disclosure.

[0063] The transmission path 200 includes a channel coding and modulation block 205, a Serial-to-Parallel (S-to-P) block 210, a size N Inverse Fast Fourier Transform (IFFT) block 215, a Parallel-to-Serial (P-to-S) block 220, a cyclic prefix addition block 225, and an up-converter (UC) 230. The reception path 250 includes a down-converter (DC) 255, a cyclic prefix removal block 260, a Serial-to-Parallel (S-to-P) block 265, a size N Fast Fourier Transform (FFT) block 270, a Parallel-to-Serial (P-to-S) block 275, and a channel decoding and demodulation block 280.

[0064] In the transmission path 200, the channel coding and modulation block 205 receives a set of information bits, applies coding (such as Low Density Parity Check (LDPC) coding), and modulates the input bits (such as using Quadrature Phase Shift Keying (QPSK) or Quadrature Amplitude Modulation (QAM)) to generate a sequence of frequency-domain modulated symbols. The Serial-to-Parallel (S-to-P) block 210 converts (such as demultiplexes) serial modulated symbols into parallel data to generate N parallel symbol streams, where N is a size of the IFFT / FFT used in gNB 102 and UE 116. The size N IFFT block 215 performs IFFT operations on the N parallel symbol streams to generate a time domain output signal. The Parallel-to-Serial block 220 converts (such as multiplexes) parallel time domain output symbols from the Size N IFFT block 215 to generate a serial time domain signal. The cyclic prefix addition block 225 inserts a cyclic prefix into the time domain signal. The up-converter 230 modulates (such as up-converts) the output of the cyclic prefix addition block 225 to an RF frequency for transmission via a wireless channel. The signal can also be filtered at a baseband before switching to the RF frequency.

[0065] The RF signal transmitted from gNB 102 arrives at UE 116 after passing through the wireless channel, and operations in reverse to those at gNB 102 are performed at UE 116. The down-converter 255 down-converts the received signal to a baseband frequency, and the cyclic prefix removal block 260 removes the cyclic prefix to generate a serial time domain baseband signal. The Serial-to-Parallel block 265 converts the time domain baseband signal into a parallel time domain signal. The Size N FFT block 270 performs an FFT algorithm to generate N parallel frequency-domain signals. The Parallel-to-Serial block 275 converts the parallel frequency-domain signal into a sequence of modulated data symbols. The channel decoding and demodulation block 280 demodulates and decodes the modulated symbols to recover the original input data stream.

[0066] Each of gNBs 101-103 may implement a transmission path 200 similar to that for transmitting to UEs 111-116 in the downlink, and may implement a reception path 250 similar to that for receiving from UEs 111-116 in the uplink. Similarly, each of UEs 111-116 may implement a transmission path 200 for transmitting to gNBs 101-103 in the uplink, and may implement a reception path 250 for receiving from gNBs 101-103 in the downlink.

[0067] Each of the components in FIGs. 2a and 2b can be implemented using only hardware, or using a combination of hardware and software / firmware. As a specific example, at least some of the components in FIGs. 2a and 2b may be implemented in software, while other components may be implemented in Configurable hardware or a combination of software and Configurable hardware. For example, the FFT block 270 and IFFT block 215 may be implemented as Configurable software algorithms, in which the value of the size N may be modified according to the implementation.

[0068] Furthermore, although described as using FFT and IFFT, this is only illustrative and should not be interpreted as limiting the scope of the present disclosure. Other types of transforms can be used, such as Discrete Fourier transform (DFT) and Inverse Discrete Fourier Transform (IDFT) functions. It should be understood that for DFT and IDFT functions, the value of variable N may be any integer (such as 1, 2, 3, 4, etc.), while for FFT and IFFT functions, the value of variable N may be any integer which is a power of 2 (such as 1, 2, 4, 8, 16, etc.).

[0069] Although FIGs. 2a and 2b illustrate examples of wireless transmission and reception paths, various changes may be made to FIGs. 2a and 2b. For example, various components in FIGs. 2a and 2b can be combined, further subdivided or omitted, and additional components can be added according to specific requirements. Furthermore, FIGs. 2a and 2b are intended to illustrate examples of types of transmission and reception paths that can be used in a wireless network. Any other suitable architecture can be used to support wireless communication in a wireless network.

[0070] FIG. 3a illustrates an example UE 116 according to the present disclosure. The embodiment of UE 116 shown in FIG. 3a is for illustration only, and UEs 111-115 of FIG. 1 can have the same or similar Configuration. However, a UE has various Configurations, and FIG. 3a does not limit the scope of the present disclosure to any specific implementation of the UE.

[0071] UE 116 includes an antenna 305, a radio frequency (RF) transceiver 310, a transmission (TX) processing circuit 315, a microphone 320, and a reception (RX) processing circuit 325. UE 116 also includes a speaker 330, a processor / controller 340, an input / output (I / O) interface 345, an input device(s) 350, a display 355, and a memory 360. The memory 360 includes an operating system (OS) 361 and one or more applications 362.

[0072] The RF transceiver 310 receives an incoming RF signal transmitted by a gNB of the wireless network 100 from the antenna 305. The RF transceiver 310 down-converts the incoming RF signal to generate an intermediate frequency (IF) or baseband signal. The IF or baseband signal is transmitted to the RX processing circuit 325, where the RX processing circuit 325 generates a processed baseband signal by filtering, decoding and / or digitizing the baseband or IF signal. The RX processing circuit 325 transmits the processed baseband signal to speaker 330 (such as for voice data) or to processor / controller 340 for further processing (such as for web browsing data).

[0073] The TX processing circuit 315 receives analog or digital voice data from microphone 320 or other outgoing baseband data (such as network data, email or interactive video game data) from processor / controller 340. The TX processing circuit 315 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. The RF transceiver 310 receives the outgoing processed baseband or IF signal from the TX processing circuit 315 and up-converts the baseband or IF signal into an RF signal transmitted via the antenna 305.

[0074] The processor / controller 340 can include one or more processors or other processing devices and execute an OS 361 stored in the memory 360 in order to control the overall operation of UE 116. For example, the processor / controller 340 can control the reception of forward channel signals and the transmission of backward channel signals through the RF transceiver 310, the RX processing circuit 325 and the TX processing circuit 315 according to well-known principles. In some embodiments, the processor / controller 340 includes at least one microprocessor or microcontroller.

[0075] The processor / controller 340 is also capable of executing other processes and programs residing in the memory 360, such as operations for channel quality measurement and reporting for systems with 2D antenna arrays as described in embodiments of the present disclosure. The processor / controller 340 can move data into or out of the memory 360 as required by an execution process. In some embodiments, the processor / controller 340 is configured to execute the application 362 based on the OS 361 or in response to signals received from the gNB or the operator. The processor / controller 340 is also coupled to an I / O interface 345, where the I / O interface 345 provides UE 116 with the ability to connect to other devices such as laptop computers and handheld computers. I / O interface 345 is a communication path between these accessories and the processor / controller 340.

[0076] The processor / controller 340 is also coupled to the input device(s) 350 and the display 355. An operator of UE 116 can input data into UE 116 using the input device(s) 350. The display 355 may be a liquid crystal display or other display capable of presenting text and / or at least limited graphics (such as from a website). The memory 360 is coupled to the processor / controller 340. A part of the memory 360 can include a random access memory (RAM), while another part of the memory 360 can include a flash memory or other read-only memory (ROM).

[0077] Although FIG. 3a illustrates an example of UE 116, various changes can be made to FIG. 3a. For example, various components in FIG. 3a can be combined, further subdivided or omitted, and additional components can be added according to specific requirements. As a specific example, the processor / controller 340 can be divided into a plurality of processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). Furthermore, although FIG. 3a illustrates that the UE 116 is configured as a mobile phone or a smart phone, UEs can be Configured to operate as other types of mobile or fixed devices.

[0078] FIG. 3b illustrates an example gNB 102 according to the present disclosure. The embodiment of gNB 102 shown in FIG. 3b is for illustration only, and other gNBs of FIG. 1 can have the same or similar Configuration. However, a gNB has various Configurations, and FIG. 3b does not limit the scope of the present disclosure to any specific implementation of a gNB. It should be noted that gNB 101 and gNB 103 can include the same or similar structures as gNB 102.

[0079] As shown in FIG. 3b, gNB 102 includes a plurality of antennas 370a-370n, a plurality of RF transceivers 372a-372n, a transmission (TX) processing circuit 374, and a reception (RX) processing circuit 376. In certain embodiments, one or more of the plurality of antennas 370a-370n include a 2D antenna array. gNB 102 also includes a controller / processor 378, a memory 380, and a backhaul or network interface 382.

[0080] RF transceivers 372a-372n receive an incoming RF signal from antennas 370a-370n, such as a signal transmitted by the UEs or other gNBs. RF transceivers 372a-372n down-convert the incoming RF signal to generate an IF or baseband signal. The IF or baseband signal is transmitted to the RX processing circuit 376, where the RX processing circuit 376 generates a processed baseband signal by filtering, decoding and / or digitizing the baseband or IF signal. RX processing circuit 376 transmits the processed baseband signal to controller / processor 378 for further processing.

[0081] The TX processing circuit 374 receives analog or digital data (such as voice data, network data, email or interactive video game data) from the controller / processor 378. TX processing circuit 374 encodes, multiplexes and / or digitizes outgoing baseband data to generate a processed baseband or IF signal. RF transceivers 372a-372n receive the outgoing processed baseband or IF signal from TX processing circuit 374 and up-convert the baseband or IF signal into an RF signal transmitted via antennas 370a-370n.

[0082] The controller / processor 378 can include one or more processors or other processing devices that control the overall operation of gNB 102. For example, the controller / processor 378 can control the reception of forward channel signals and the transmission of backward channel signals through the RF transceivers 372a-372n, the RX processing circuit 376 and the TX processing circuit 374 according to well-known principles. The controller / processor 378 can also support additional functions, such as higher-level wireless communication functions. For example, the controller / processor 378 can perform a Blind Interference Sensing (BIS) process such as that performed through a BIS algorithm, and decode a received signal from which an interference signal is subtracted. A controller / processor 378 may support any of a variety of other functions in gNB 102. In some embodiments, the controller / processor 378 includes at least one microprocessor or microcontroller.

[0083] The controller / processor 378 is also capable of executing programs and other processes residing in the memory 380, such as a basic OS. The controller / processor 378 can also support channel quality measurement and reporting for systems with 2D antenna arrays as described in embodiments of the present disclosure. In some embodiments, the controller / processor 378 supports communication between entities such as web RTCs. The controller / processor 378 can move data into or out of the memory 380 as required by an execution process.

[0084] The controller / processor 378 is also coupled to the backhaul or network interface 382. The backhaul or network interface 382 allows gNB 102 to communicate with other devices or systems through a backhaul connection or through a network. The backhaul or network interface 382 can support communication over any suitable wired or wireless connection(s). For example, when gNB 102 is implemented as a part of a cellular communication system, such as a cellular communication system supporting 5G or new radio access technology or NR, LTE or LTE-A, the backhaul or network interface 382 can allow gNB 102 to communicate with other gNBs through wired or wireless backhaul connections. When gNB 102 is implemented as an access point, the backhaul or network interface 382 can allow gNB 102 to communicate with a larger network, such as the Internet, through a wired or wireless local area network or through a wired or wireless connection. The backhaul or network interface 382 includes any suitable structure that supports communication through a wired or wireless connection, such as an Ethernet or an RF transceiver.

[0085] The memory 380 is coupled to the controller / processor 378. A part of the memory 380 can include an RAM, while another part of the memory 380 can include a flash memory or other ROMs. In certain embodiments, a plurality of instructions, such as the BIS algorithm, are stored in the memory. The plurality of instructions are Configured to cause the controller / processor 378 to execute the BIS process and decode the received signal after subtracting at least one interference signal determined by the BIS algorithm.

[0086] As will be described in more detail below, the transmission and reception paths of gNB 102 (implemented using RF transceivers 372a-372n, TX processing circuit 374 and / or RX processing circuit 376) support aggregated communication with FDD cells and TDD cells.

[0087] Although FIG. 3b illustrates an example of gNB 102, various changes may be made to FIG. 3b. For example, gNB 102 can include any number of each component shown in FIG. 3a. As a specific example, the access point can include many backhaul or network interfaces 382, and the controller / processor 378 can support routing functions to route data between different network addresses. As another specific example, although shown as including a single instance of the TX processing circuit 374 and a single instance of the RX processing circuit 376, gNB 102 can include multiple instances of each (such as one for each RF transceiver).

[0088] In order to enhance the scheduling efficiency of the 5G wireless communication system, the base station needs to obtain channel state information (CSI) to schedule according to the CSI fed back by the terminal equipment. However, how to further enhance the performance of CSI reporting is a problem to be solved.

[0089] Hereinafter, various embodiments of the present application will be described in detail with reference to the drawings.

[0090] FIG. 4 illustrates a method 400 performed by a user equipment (UE) according to various embodiments of the present disclosure. The method 400 includes: at 401, the UE receives a first CSI reporting configuration (e.g., CSI-ReportConfig). At 402, optionally, the UE determines and / or reports the CSI based on the first CSI reporting configuration, wherein the CSI includes a predicted beam ID and / or a predicted L1-RSRP, and the CSI reporting configuration includes a report quantity parameter, information for indicating an artificial intelligence (AI)-enabled function (also called functionality information or second information, etc., and its name is not limited in this application), information for a model related to the AI-enabled feature (also called model information or third information, etc., and its name is not limited in this application), spatial information, time information, and first information for indicating enabling or disabling of L1-RSRP reporting. Optionally, the UE reports the CSI corresponding to the first CSI reporting configuration. Optionally, the UE determines and / or reports the CSI based on at least one of the report quantity parameter included in the first CSI reporting configuration, the functionality information included in the first CSI reporting configuration, the model information included in the first CSI reporting configuration, the spatial information included in the first CSI reporting configuration, the time information included in the first CSI reporting configuration, and the first information for enabling or disabling the L1-RSRP reporting. Here, the CSI may be predicted CSI. Optionally, the CSI includes the predicted beam identification (ID) and / or the predicted Layer 1-Reference Signal Received Power (L1-RSRP). In this application, the term “beam ID” can be replaced by “beam information” or “CSI-RS resource indicator (CRI)” or “SS / PBCH Block Resource indicator (SSBRI)” or “CRI and / or SSBRI” or “beam resource ID” or “downlink beam resource ID” or “downlink beam information”. In this application, the CSI reported by the UE may be the CSI reported by the UE in a report or in a report instance. For example, the reported CSI may include one or more predicted beam IDs and one or more L1-RSRPs. Optionally, the one or more predicted beam IDs and one or more L1-RSRPs are one-to-one mapped. Optionally, the L1-RSRP may be the predicted L1-RSRP. Optionally, the L1-RSRP may be the predicted L1-RSRP and a measured L1-RSRP. The predicted L1-RSRP is described below as an example.

[0091] The first CSI reporting configuration may be associated with / correspond to a resource set. Optionally, the resource set may be a resource set for measurement. Optionally, the resource set (or resource set for measurement) may be used for channel measurement and / or interference measurement. Optionally, the resource set for channel measurement may be called a second set. Optionally, the first CSI reporting configuration may be associated with / configured with / correspond to the second set. Optionally, the second set may include SSB resources or CSI-RS resources. Optionally, the second set may be an SSB resource set or a CSI-RS resource set. Optionally, the resource set may be resource set(s) indicated by a CSI resource Configuration parameter CSI-ResourceConfig. Optionally, the resource set may include the CSI-RS resource set (for example, the resource set indicated by a parameter NZP-CSI-RS-ResourceSet). Optionally, the resource set may include the SSB resource set (for example, the resource set indicated by a parameter CSI-SSB-ResourceSet). The UE may perform measurement (or perform channel measurement) on reference signals in the resource set.

[0092] The UE receives the first CSI reporting configuration. The UE determines and / or reports the CSI based on at least one of the report quantity parameter corresponding to / included in the first CSI reporting configuration, the functionality information corresponding to / included in the first CSI reporting configuration, the model information corresponding to / included in the first CSI reporting configuration, the spatial information corresponding to / included in the first CSI reporting configuration, the time information corresponding to / included in the first CSI reporting configuration, the first information for enabling or disenabling the L1-RSRP corresponding to / included in the first CSI reporting configuration, wherein the CSI includes at least one of the predicted beam ID and / or the predicted L1-RSRP (corresponding to the predicted beam ID).

[0093] For beam prediction at UE-side, the UE needs to perform spatial domain and / or time domain beam prediction on the downlink beam based on the measurement of resources in the resource set. In order to obtain respective information for spatial domain and / or time domain beam prediction for the UE, the first CSI reporting configuration configured by the base station may include at least one of the report quantity parameter, the functionality information, the model information, the spatial information, the time information and the first information. After obtaining the information, the UE may report the predicted beam ID and / or the predicted L1-RSRP based on the information. Therefore, the base station may use the predicted beam ID and / or the predicted L1-RSRP reported by the UE for subsequent scheduling, thus improving the efficiency of the communication system.

[0094] The report quantity parameter (also called the report quantity) is further explained below.

[0095] The first CSI reporting configuration may include / be configured with a first parameter for indicating the report quantity (or the CSI related quantities to report). For example, the first parameter may be a report quantity parameter (e.g., reportQuantity). The first parameter may be set to different values, and each value may correspond to a different report quantity. For example, if the UE is configured with a CSI-ReportConfig with the higher layer parameter reportQuantity set to 'none', then the UE shall not report any quantity for the CSI-ReportConfig. For example, if the UE is configured with a CSI-ReportConfig with the higher layer parameter reportQuantity not set to 'none', then the UE shall report quantity for the CSI-ReportConfig. The first parameter included in the first CSI reporting configuration / the first CSI reporting configuration is configured with, or the report quantity parameter included in the first CSI reporting configuration / the first CSI reporting configuration is configured with, may be called “report quantity corresponding to the first CSI reporting configuration” or “report quantity parameter included in the first CSI reporting configuration”.

[0096] The functionality information and / or the model information are further explained below.

[0097] For an artificial intelligence (AI) / neural network (ML) model at UE-side, the UE and the network equipment need to align the model / feature (for example, the AI / ML related model / feature) used for CSI report (for example, the CSI report corresponding to the first CSI reporting configuration). The following method may be used to clarify the feature or model used for the CSI report. Optionally, the first CSI reporting configuration, or reference signal resources (or a reference signal resource set) corresponding to the first CSI reporting configuration, is for (or corresponds to) the AI / ML related model / feature. Optionally, the first CSI reporting configuration, or configuration information for the reference signal resources (or the reference signal resource set) corresponding to the first CSI reporting configuration, includes the functionality information and / or the model information. Optionally, the functionality information and / or the model information are related to the AI / ML. Optionally, the functionality information and / or the model information included in the first CSI reporting configuration is based on the supported AI-enabled model / feature reported by the UE. Here, “model” may be used interchangeably with “AI / ML model”. Optionally, the AI / ML related model / feature may be / may be defined as the AI-enabled model / feature. Optionally, the AI-enabled model / feature refers to a feature / model where AI / ML may be used. Optionally, the UE may report the AI-enabled feature supported by the UE. For example, the UE may report the AI-enabled feature supported by the UE through UE capability signaling. In this application, “UE capability signaling” may be used interchangeably with “UE capability”. For example, the base station indicates the AI-enabled feature used by the UE according to the supported AI-enabled feature reported by the UE. Optionally, the AI-enabled feature includes at least one of the followings:

[0098] ● downlink transmission beam prediction;

[0099] ● CSI prediction;

[0100] ● CSI compression.

[0101] In this application, the term “downlink transmission beam prediction” may be used interchangeably with “beam prediction” or “downlink beam prediction” or “UE-side beam prediction” or “UE-side downlink beam prediction” or “UE-side downlink transmission beam prediction”.

[0102] It should be noted that whether the UE supports downlink transmission beam prediction is based on the UE capability. For example, the UE may report / indicate whether the UE supports downlink transmission beam prediction through the UE capability signaling. For example, the UE may or may not support downlink transmission beam prediction in a predefined manner.

[0103] It should be noted that whether the UE supports the L1-RSRP prediction corresponding to the downlink transmission beam prediction is based on the UE capability. For example, the UE may report / indicate whether the UE supports the L1-RSRP prediction corresponding to the downlink transmission beam through the UE capability signaling. For example, the UE may support or not support the L1-RSRP prediction corresponding to the downlink transmission beam in a predefined way.

[0104] Optionally, the downlink transmission beam prediction may include at least one of spatial domain downlink transmission beam prediction, time domain downlink transmission beam prediction, and spatial domain and time domain downlink transmission beam prediction. Optionally, the downlink transmission beam prediction may include at least one of spatial domain downlink transmission beam prediction and L1-RSRP prediction, time domain downlink transmission beam prediction and L1-RSRP prediction, and spatial domain and time domain downlink transmission beam prediction and L1-RSRP prediction.

[0105] Optionally, the first CSI reporting configuration may include the model information. Optionally, the model information may be for the feature indicated by the functionality information (or information for the AI / ML-enabled feature). For example, for the AI / ML-enabled feature indicated by the functionality information, the corresponding model information may indicate the ID of the model corresponding to / used by the feature. Thus, the UE may know that the first CSI reporting configuration is based on (or applies) the corresponding feature and / or model for model inference based on the functionality information / model information included in the first CSI reporting configuration. Optionally, association between the feature and the corresponding model may be predefined or reported by the UE. For example, the association between the feature and the corresponding model may be indicated by the UE capability signaling. Therefore, the base station and UE may have common understanding of the feature / model corresponding to the CSI report, so as to better manage the feature / model, improve the performance of the AI / ML in the communication system, and further improve the efficiency of the communication system.

[0106] For the AI / ML model (for example, UE-side AI / ML model), UE may perform CSI reporting and / or CSI prediction based on model inference. The UE and the network equipment need to have common understanding of the feature of the CSI reporting in order to perform corresponding operations. The following method may clarify the feature (or the functionality information included in) corresponding to the first CSI reporting configuration. Optionally, the functionality information (for example, the functionality information included in the first CSI reporting configuration) may be related to the AI / ML. Optionally, the first CSI reporting configuration includes the functionality information, which is used to indicate that the first CSI reporting configuration is for model inference (or is to determine / report the CSI based on model inference). For example, when the first CSI reporting configuration includes the functionality information, the CSI report corresponding to the first CSI reporting configuration is determined based on model inference. For example, the UE determines that the CSI report corresponding to the first CSI reporting configuration (or reported CSI) is determined based on model inference by receiving at least one of downlink control information (DCI), media access control control element (MAC-CE) and radio resource control (RRC) signaling from the base station. Optionally, the reported CSI may be determined based on the model output.

[0107] The Spatial information is further explained below.

[0108] The UE receives the first CSI reporting configuration (e.g., CSI-ReportConfig). The first CSI reporting configuration may include the spatial information. The UE may determine a beam ID set based on the spatial information. Optionally, the first CSI reporting configuration may include / be associated with / be configured with / indicate the beam ID set (or, a first set). Optionally, the beam ID set may be referred as the first set. Optionally, the first set may be for prediction. Optionally, the first set may be used for prediction. Optionally, a size of the first set may be K1. Optionally, K1 is indicated by the spatial information. Optionally, the first set includes integers ranged from 0 to K1-1. Optionally, each integer ranged from 0 to K1-1 corresponds to a beam. Optionally, the UE determines the reported predicted CSI based on channel measurement for the second set. Optionally, a value of the predicted CSI may be an integer ranged from 0 to K1-1. Optionally, the predicted beam ID reported (by the UE) corresponding to the first CSI reporting configuration is from the beam ID set. For example, the spatial information may include a bitmap for indicating one or more beam IDs (and the one or more beam IDs constitute a beam ID set). For example, the spatial information may explicitly indicate one or more beam IDs (and the one or more beam IDs constitute a beam ID set). Optionally, the spatial information may include / indicate a mapping relationship and / or association between the resource set for measurement corresponding to the first CSI reporting configuration and the beam ID set. Optionally, the mapping relationship and / or association includes a quasi-co-location (QCL) relationship between the resources in the resource set for measurement and beams / reference signals / reference signal resources corresponding to the beam ID set. Optionally, the mapping relationship and / or association includes an angular relationship / position relationship between the resources in the resource set for measurement and beams / reference signals / reference signal resources corresponding to the beam ID set. Optionally, the beam ID set may be a CSI-RS / SSB resource set. Optionally, when the beam ID set is the CSI-RS / SSB resource set, the reported beam ID is the predicted SSBRI or the predicted CRI. Optionally, when the beam ID set is the CSI-RS / SSB resource set, the UE does not perform measurement for the CSI-RS / SSB resource set. Optionally, when the beam ID set is the CSI-RS / SSB resource set, the UE determines whether to perform measurement for the CSI-RS / SSB resource set based on the UE capability or the indication by the base station (for example, the indication of the first CSI reporting configuration). For example, when the base station configures enabling information, the UE performs measurement for the CSI-RS / SSB resource set. For example, when the base station configures disabling information (or does not configure the enabling information), the UE does not perform measurement for the CSI-RS / SSB resource set. The above provides a method for the UE to determine whether the resources in the first set are measured or not, so that the UE does not measure the first set in some cases to reduce power consumption, or measures the first set in some cases so that the UE may select the AI model according to a measurement result for the first set.

[0109] Optionally, the UE may be indicated / configured with information for determining the association between the first set and the second set. Optionally, the first CSI reporting configuration may be configured with / be associated with / correspond to information for determining the association between the first set and the second set. Optionally, the information for determining the association between the first set and the second set may be referred as association information for the first set and the second set. Optionally, for the first CSI reporting configuration, the UE may be configured with the association information for the first set and the second set. Optionally, the spatial information includes the association information for the first set and the second set. For example, the UE may be configured with the associated information for the first set and the second set through the spatial information included in the first CSI reporting configuration. Optionally, the association information for the first set and the second set may include the mapping relationship(s) between elements of the first set and elements of the second set. For example, for a mapping relationship, the association information indicates that the k1-th element (1 ≤ k1 ≤ K1) in the first set is associated with the k2-th element (1 ≤ k2 ≤ K2) in the second set, where K1 is the size of the first set and K2 is the size of the second set. For example, for a mapping relationship, the association information includes a parameter k1 and a parameter k2. Parameter k1 and parameter k2 indicate that the k1-th element (1 ≤ k1 ≤ K1) in the first set is associated with the k2-th element (1 ≤ k2 ≤ K2) in the second set, where K1 is the size of the first set and K2 is the size of the second set. Optionally, the association of an element in the first set with an element in the second set may be that the element in the first set is associated with the element in the second set in spatial domain (for example, the element in the first set is quasi-co-located with the element in the second set or the element in the first set and the element in the second set is quasi-co-located of type D). Optionally, the association between an element in the first set and an element in the second set may be that the element in the first set and the element in the second set correspond to a same beam (or correspond to a same spatial filter). Optionally, the k1-th element in the first set refers to the k1-th resource in the first set (for example, the resource with the k1-th largest / smallest resource ID in the first set, or the resource corresponding to / associated with the k1-th entry in the configuration information associated with the first set). Optionally, the k1-th element in the first set refers to the k1-th precoding vector in the first set (for example, the precoding vector with the k1-th largest / smallest resource ID in the first set, or the precoding vector corresponding to / associated with the k1-th entry in the configuration information associated with the first set). Optionally, the k1-th element in the first set refers to an integer with a value of k1-1 in K1 integers. Optionally, the k1-th element in the first set refers to a predicted value (or a predicted ID or a predicted indicator) with a value of k1-1. Optionally, the k2-th element in the second set refers to the k2-th resource in the second set (for example, the resource with the k2-th largest / smallest resource ID in the second set, or the resource corresponding to / associated with the k2-th entry in the configuration information associated with the second set). The obtaining by the UE of the association information for the first set and the second set provided by the base station can make the UE perform inference using the AI / ML model complying with the association information for the first set and the second set, improves the reliability of the AI / ML model inference, thus improves the performance of the communication system. The spatial information provides the UE with necessary information for spatial domain beam prediction, so that the UE may correctly perform spatial domain prediction, thus improves the precision of the spatial domain beam prediction.

[0110] The time information is further explained below.

[0111] Here, the description of the beam ID may be equivalently applied to the description of “CRI” and / or “SSBRI”.

[0112] The UE receives the first CSI reporting configuration (e.g., CSI-ReportConfig). The first CSI reporting configuration may include the time information. The UE may determine a time interval corresponding to the predicted beam ID corresponding to the first CSI reporting configuration based on the time information. Optionally, when the first CSI reporting configuration includes the time information, the predicted beam ID corresponding to the first CSI reporting configuration is associated with one or more time intervals (or, F time intervals) determined based on the time information. Optionally, the UE may determine F time intervals corresponding to the predicted beam ID corresponding to the first CSI reporting configuration based on the time information. Optionally, F may be one of 1, 2, 3, 4, 5, 6, 7 and 8. Methods for determining F time intervals through the time information may be at least one of the followings:

[0113] Method 1: the time information includes a number (F) of time intervals and a time offset of an earliest time interval in F time intervals. A time unit where the earliest time interval in F time intervals is located, or a starting position / an ending position (e.g., a starting slot or a starting symbol or an ending slot or an ending symbol) of the earliest time interval in F time intervals, is determined with reference to the time unit (e.g., slot or symbol) where the CSI report carrying the beam ID is located and / or the time offset. The time offset (K) may be an uplink time offset (for example, an uplink slot offset or an uplink symbol offset) or a downlink time offset (for example, a downlink slot offset or a downlink symbol offset). For example, when the time offset is the uplink slot offset, the starting slot of the earliest time interval in F time intervals (or the slot where the earliest interval in F time intervals is located) is or . For example, when the time offset is the downlink slot offset, the starting slot of the earliest time interval in F time intervals (or the slot where the earliest interval in F time intervals is located) is or . Here, n’ refers to the uplink slot where the CSI report (carrying the beam ID) is located, and and are downlink subcarrier spacing configuration and uplink subcarrier spacing configuration, respectively. After the time position (e.g., starting position / ending position) of the earliest time interval in F time intervals is determined, time positions (e.g., starting positions / ending positions) of other F-1 time intervals need to be further determined. If the slot where the earliest interval in F time intervals is located or the starting slot / ending slot of the earliest time interval in F time intervals is slot X, then the slot where the earliest interval in F time intervals is located or the starting slot / ending slot of the earliest time interval in F time intervals is X+(f-1)*S (for example, 1 ≤ f ≤ F). Here, S refers to separation between two neighboring time intervals in F time intervals. Optionally, S may be provided / configured by the time information. Optionally, S may be predefined (e.g., S is 1 slot). Optionally, S is determined based on periodicity of the measurement resources in the resource set for measurement corresponding to the CSI report or separation between measurement resources. For example, when the resources in the resource set for measurement corresponding to the CSI report are periodic or semi-persistent, S is determined based on the periodicity of the measurement resources in the resource set for measurement corresponding to the CSI report (for example, a positive integer multiple of the periodicity of the measurement resources). For example, when the resources in the resource set for measurement corresponding to the CSI report are aperiodic, S is determined based on time separation of the measurement resources in the resource set for measurement corresponding to the CSI report (for example, S is based on the time separation between neighboring measurement resources in the resource set for measurement). For example, if the slot where the earliest time interval in F time intervals is located or the starting slot of the earliest time interval in F time intervals is slot #1, and the slot separation is 2, then the slot where the next time interval in F time intervals is located or the starting slot of the next slot in F time intervals is slot #3, the next slot is slot #5, and so on. Optionally, each of F time intervals may have the same length L (L slots or L symbols). Optionally, L may be predefined, for example, 1 slot, 2 slots, 3 slots, or 4 slots, or for example, 1 symbol, 2 symbols, 3 symbols, or 4 symbols. Optionally, L may be determined based on the time information. For example, the time information includes a value of L.

[0114] Method 2: Method 2 is similar to Method 1, except that the starting time unit / ending time unit of the earliest time interval in F time intervals is determined with reference to the time unit (e.g., slot or symbol) of the CSI reference resource corresponding to the CSI report carrying the beam ID and / or the time offset. For example, when the time offset is the uplink slot offset, the starting slot of the earliest time interval in F time intervals (or the slot where the earliest time interval in F time intervals is located) is or . is a parameter for determining the slot where the CSI reference resource (corresponding to the CSI report) is located. For example, when the time offset is the downlink slot offset, the starting slot of the earliest time interval in F time intervals (or the slot where the earliest time interval in F time intervals is located) is or . Here, n’ refers to the uplink slot where the CSI report (carrying the beam ID) is located, and and are downlink subcarrier spacing configuration and uplink subcarrier spacing configuration, respectively.

[0115] Method 3: the time information includes F time offsets, wherein each time offset corresponds to a time interval (for example, is for determining the corresponding time interval). For example, the f-th time offset (e.g., 1 ≤ f ≤ F) is used to determine the starting position / ending position of the f-th time interval. The time unit where a time interval (for example, the f-th time interval) is located or the starting position / ending position of a time interval (for example, the starting slot or the starting symbol or the ending slot or the ending symbol) is determined with reference to the time unit (for example, the slot or the symbol) where the CSI report carrying the beam ID is located and / or the time offset. The time offset (K) corresponding to the time interval may be an uplink time offset (for example, an uplink slot offset or an uplink symbol offset) or a downlink time offset (for example, a downlink slot offset or a downlink symbol offset). For example, when the time offset (for example, the f-th time offset) is the uplink slot offset, the starting slot of the corresponding time interval (for example, the f-th time interval) (or the slot where the corresponding time interval is located) is or . For example, when the time offset is the downlink slot offset, the starting slot of the earliest time interval in F time intervals (or the slot where the earliest time interval in F time intervals is located) is or .

[0116] Here, n’ refers to the uplink slot where the CSI report (carrying the beam ID) is located, and and are downlink subcarrier spacing configuration and uplink subcarrier spacing configuration, respectively. Optionally, each of F time intervals may have the same length L (L slots or L symbols). Optionally, L may be predefined, for example, 1 slot, 2 slots, 3 slots, or 4 slots, or for example, 1 symbol, 2 symbols, 3 symbols, or 4 symbols. Optionally, L may be determined based on the time information. For example, the time information includes the value of L.

[0117] Method 4: the time information includes F time offsets, wherein each time offset corresponds to a time interval (for example, is for determining the corresponding time interval). For example, the f-th time offset (e.g., 1 ≤ f ≤ F) is used to determine the starting position / ending position of the f-th time interval. The time unit where a time interval (for example, the f-th time interval) is located or the starting position / ending position of a time interval (for example, the starting slot or the starting symbol or the ending slot or the ending symbol) is determined with reference to the time unit (for example, the slot or the symbol) where the CSI reference resource corresponding to the CSI report carrying the beam ID is located and / or the time offset. The time offset (K) corresponding to the time interval may be an uplink time offset (for example, an uplink slot offset or an uplink symbol offset) or a downlink time offset (for example, a downlink slot offset or a downlink symbol offset). For example, when the time offset (for example, the f-th time offset) is the uplink slot offset, the starting slot of the corresponding time interval (for example, the f-th time interval) (or the slot where the corresponding time interval is located) is or . For example, when the time offset is the downlink slot offset, the starting slot of the earliest time interval in F time intervals (or the slot where the earliest time interval in F time intervals is located) is or . Here, n’ refers to the uplink slot where the CSI report (carrying the beam ID) is located, and and are downlink subcarrier spacing configuration and uplink subcarrier spacing configuration, respectively. Optionally, each of F time intervals may have the same length L (L slots or L symbols). Optionally, L may be predefined, for example, 1 slot, 2 slots, 3 slots, or 4 slots, or for example, 1 symbol, 2 symbols, 3 symbols, or 4 symbols. Optionally, L may be determined based on the time information. For example, the time information includes the value of L.

[0118] Optionally, when the first CSI reporting configuration includes the time information, the predicted L1-RSRP corresponding to the first CSI reporting configuration is associated with one or more time intervals (or, F time intervals) determined based on the time information. Optionally, the UE may determine F time intervals corresponding to the predicted L1-RSRP corresponding to the first CSI reporting configuration based on the time information. Optionally, the predicted L1-RSRP is associated with the predicted beam ID (for example, in one-to-one correspondence, or in one-to-many mapping, or in many-to-one mapping).

[0119] The parameter (for example, the parameter included in the time information) for determining one or more time intervals corresponding to / associated with the predicted L1-RSRP and the parameter for determining one or more time intervals corresponding to the predicted L1-RSRP may be the same parameter or different parameters (for example, the time information includes the parameter for determining one or more time intervals corresponding to the predicted beam ID and the parameter for determining the predicted L1-RSRP, respectively). Refer to the method of determining one or more time intervals associated with the predicted beam ID based on the parameter above for the method of determining one or more time intervals associated with the predicted L1-RSRP based on the parameter.

[0120] A predicted beam ID is associated with a time interval, which may be understood as that the UE prefers / recommends the beam ID predicted for the corresponding / associated time interval, or the UE prefers / recommends the predicted beam ID for scheduling by the base station for the corresponding / associated time interval. A predicted L1-RSRP is associated with a time interval, which may be understood as that the UE prefers / recommends the L1-RSRP for the corresponding / associated time interval, or the UE prefers / recommends the L1-RSRP for scheduling by the base station for the corresponding / associated time interval. In this application, the term “time interval” may be used interchangeably with the terms “slot interval”, “symbol interval” and “time instance”.

[0121] Optionally, each of F time intervals may be associated with NF beam IDs. For example, each of F time intervals has NF beam IDs predicted for the corresponding time interval. Optionally, the value of NF may be predefined (for example, one of 1, 2, 3 and 4), or the value of NF may be indicated by a RRC parameter / MAC-CE signaling / DCI, or the value of N may be indicated by the UE capability signaling.

[0122] Optionally, the time information may include measurement window information. The measurement window information may include / indicate a number of measurement windows, the starting point / ending point of each measurement window, and the width of the measurement window. The UE may determine the measurement window of the measurement resources in the resource set for measurement corresponding to the first CSI reporting configuration through the measurement window information. For example, the UE determines NF beam IDs corresponding to each of F time intervals according to the measurement in X measurement windows, wherein X and the X measurement windows are determined based on the measurement window information.

[0123] Optionally, the time information may include measurement occasion information. For example, the time information may include a number of measurement occasions to indicate a number of measurement occasions on which the CSI report is based. For example, the time information may include the number (Y1) of measurement occasions to indicate that the CSI report is determined based on the (latest) Y1 measurement occasions. For example, the time information may include the number (Y1) of measurement occasions to indicate that the CSI report is determined based on the latest consecutive Y1 measurement occasions no later than the CSI reference resources. Here, the indication of the measurement occasion information in the time information is exemplary, and the measurement occasion information may also be indicated by the UE capability signaling.

[0124] The time information provides the UE with necessary information for time domain beam prediction, so that the UE may correctly perform time domain prediction, thereby improving the accuracy of the time domain beam prediction.

[0125] The first information is further explained below.

[0126] The UE receives the first CSI reporting configuration (e.g., CSI-ReportConfig). The first CSI reporting configuration may or may not include the first information. The first information is used to enable or disable the L1-RSRP report. For example, when the first CSI reporting configuration includes the first information and the first information indicates that the predicted L1-RSRP is disabled, the UE does not report the predicted L1-RSRP, and / or the UE reports the predicted beam ID. For example, when the first CSI reporting configuration is not configured with the first information, the UE does not report the predicted L1-RSRP, and / or the UE reports the predicted beam ID. For example, when the first CSI reporting configuration includes the first information and the first information indicates that the predicted L1-RSRP is enabled, the UE reports the predicted L1-RSRP, and / or the UE reports the predicted beam ID.

[0127] The first information may facilitate the base station to flexibly choose whether to report (predict) the L1-RSRP, which improves the flexibility of the communication system.

[0128] The usage of determining the CSI corresponding to the first CSI reporting configuration through the time information and / or the spatial information included in the first CSI reporting configuration will be described below.

[0129] When the first CSI reporting configuration includes the spatial information, the CSI (for example, the predicted beam ID and / or the predicted L1-RSRP) corresponding to the first CSI reporting configuration is used for spatial domain downlink beam prediction.

[0130] When the first CSI reporting configuration includes the time information, the CSI (for example, the predicted beam ID and / or the predicted L1-RSRP) corresponding to the first CSI reporting configuration is used for time domain downlink beam prediction.

[0131] When the first CSI reporting configuration includes the spatial information and the first CSI reporting configuration includes the time information, the CSI (for example, predicted beam ID and / or predicted L1-RSRP) corresponding to the first CSI reporting configuration is used for spatial domain and time domain downlink beam prediction.

[0132] When the report quantity corresponding to the first CSI reporting configuration is set to ‘cri-RSRP’ or ‘ssb-Index-RSRP’ and the first CSI reporting configuration includes the time information, the CSI (for example, the predicted beam ID and / or the predicted L1-RSRP) corresponding to the first CSI reporting configuration is used for time domain downlink beam prediction.

[0133] When the report quantity corresponding to the first CSI reporting configuration is set to ‘cri-RSRP’ or ‘ssb-Index-RSRP’ and the first CSI reporting configuration does not include the spatial information and the first CSI reporting configuration includes the time information, the CSI (for example, the predicted beam ID and / or the predicted L1-RSRP) corresponding to the first CSI reporting configuration is used for time domain downlink beam prediction.

[0134] Through different parameter combinations, the UE and the base station may have the same understanding of the corresponding CSI usage, thus improving the reliability of the communication system.

[0135] Methods for the UE to determine and / or report the CSI by setting the report quantity parameter will be explained below.

[0136] The UE receives the first CSI reporting configuration (e.g., CSI-ReportConfig). Optionally, the UE determines and / or reports the CSI based on the report quantity parameter included in (corresponding to) the first CSI reporting configuration, wherein the CSI includes at least one of the predicted beam ID and / or the predicted L1-RSRP (corresponding to the predicted beam ID). For example, when a first condition is satisfied (or when the first CSI reporting configuration satisfies the first condition), the UE determines and / or reports the predicted beam ID and / or the predicted L1-RSRP (corresponding to the predicted beam ID).

[0137] An implementation method of the first condition is given below.

[0138] The first condition (or the first condition satisfied by the CSI report) may include at least one of the followings:

[0139] ● the report quantity corresponding to the first CSI reporting configuration is set to a first value; for example, the first value is ‘Predicted-cri’ or ‘Predicted-ssb-Index’ or ‘Predicted-beam-index’; for example, the first value is ‘Spatial-Predicted-cri’ or ‘Spatial-Predicted-ssb-Index’ or ‘Spatial-Predicted-beam-index’;

[0140] ● the report quantity corresponding to the first CSI reporting configuration is set to a second value; for example, the second value is ‘Predicted-cri-RSRP’ or ‘Predicted-ssb-Index-RSRP’ or ‘Predicted-beam-index-RSRP’; for example, the second value is ‘Spatial-Predicted-cri-RSRP’ or ‘Spatial-Predicted-ssb-Index-RSRP’ or ‘Spatial-Predicted-beam-index-RSRP’ or ‘cri-RSRP’ or ‘ssb-Index-RSRP’.

[0141] Optionally, when the report quantity corresponding to the first CSI reporting configuration is set to the first value, the UE reports the predicted beam ID. Optionally, when the report quantity corresponding to the first CSI reporting configuration is set to the first value, the UE reports one or more (different) predicted beam IDs. Optionally, a number of the one or more (different) predicted beam IDs is N (N≥1). Optionally, the number of the one or more predicted beam IDs reported by the UE may be predefined (for example, 1 or 2), or indicated by a radio resource control (RRC) parameter / media access control control element (MAC-CE) signaling / downlink control information (DCI), or indicated by the UE capability signaling.

[0142] Optionally, when the report quantity corresponding to the first CSI reporting configuration is set to the second value, the UE reports the predicted beam ID and the predicted L1-RSRP.

Optionally, the value of N may be predefined (e.g., 1 or 2), or the value of N may be indicated by a RRC parameter / MAC-CE signaling / DCI, or the value of N may be indicated by the UE capability signaling. The above methods may (explicitly) determine the content included in the corresponding reported CSI according to the report quantity parameter included in the first CSI reporting configuration, avoiding using additional information to indicate the content in the reported CSI, thereby reducing information bits of the indication and improving the efficiency of the communication system.

[0143] Methods for the UE to determine and / or report the CSI through the report quantity parameter and the information for enabling or disabling the L1-RSRP reporting will be explained below.

[0144] The UE receives the first CSI reporting configuration (e.g., CSI-ReportConfig). Optionally, the UE determines and / or reports the CSI based on the report quantity parameter and the first information included in the first CSI reporting configuration, wherein the CSI includes at least one of the predicted beam ID and / or the predicted L1-RSRP (corresponding to the predicted beam ID). For example, the first information may be used to enable or disable the predicted L1-RSRP.

[0145] Optionally, when the report quantity corresponding to the first CSI reporting configuration is set to a first value (for example, the first value is ‘Predicted-cri’ or ‘’Predicted-ssb-Index’ or ‘Predicted-beam-index’) and the first information indicates that the (predicted) L1-RSRP is disabled, the UE reports the predicted beam ID. Optionally, when the report quantity corresponding to the first CSI reporting configuration is set to the first value and the first information indicates that the (predicted) L1-RSRP is disabled, the UE reports one or more (different) predicted beam IDs. Optionally, the number of the one or more (different) predicted beam IDs is N (N≥1). Optionally, the number of the one or more predicted beam IDs reported by the UE may be predefined (for example, 1 or 2), or indicated by a radio resource control (RRC) parameter / media access control control element (MAC-CE) signaling / downlink control information (DCI), or indicated by the UE capability signaling.

[0146] Optionally, when the report quantity corresponding to the first CSI reporting configuration is set to the first value (for example, the first value is ‘Predicted-cri’ or ‘’Predicted-ssb-Index’ or ‘Predicted-beam-index’) and the first information is not configured, the UE reports the predicted beam ID. Optionally, when the report quantity corresponding to the first CSI reporting configuration is set to the first value and the first information is not configured, the UE reports one or more (different) predicted beam IDs. Optionally, the number of the one or more (different) predicted beam IDs is N (N≥1). Optionally, the number of the one or more predicted beam IDs reported by the UE may be predefined (for example, 1 or 2), or indicated by a radio resource control (RRC) parameter / media access control control element (MAC-CE) signaling / downlink control information (DCI), or indicated by the UE capability signaling.

Optionally, when the report quantity corresponding to the first CSI reporting configuration is set to the first value and the first information indicates that the (predicted) L1-RSRP is enabled, the UE reports one or more (different) predicted beam IDs. Optionally, the number of the one or more (different) predicted beam IDs is N (N≥1).

[0148] The above methods may determine the content included in the corresponding reported CSI through the report quantity parameter and / or the information for enabling or disabling the L1-RSRP reporting corresponding to the first CSI report, thereby flexibly determining the content in the reported CSI and improving the flexibility of the communication system.

[0149] Methods for the UE to determine the CSI report based on the functionality information and / or the model information included in the first CSI reporting configuration will be explained below.

[0150] The UE receives the first CSI reporting configuration (e.g., CSI-ReportConfig). The first CSI reporting configuration includes / corresponds to the functionality information and / or the model information.

[0151] Optionally, when the functionality information included in the first CSI reporting configuration indicates (the AI-enabled feature is) downlink beam prediction and / or the functionality information indicates that the first CSI reporting configuration is CSI reporting based on model inference, the UE determines and / or reports the predicted beam ID.

[0152] Optionally, when the functionality information included in the first CSI reporting configuration indicates (the AI-enabled feature is) downlink beam prediction and L1-RSRP prediction and / or the functionality information indicates that the first CSI reporting configuration is CSI reporting based on model inference, the UE determines and / or reports the predicted beam ID and predicted L1-RSRP corresponding to the predicted beam ID.

[0153] Optionally, when the functionality information included in the first CSI reporting configuration indicates that the first CSI reporting configuration is CSI reporting based on model inference, and / or the functionality information included in the first CSI reporting configuration indicates that the output of the model includes the beam ID, the UE determines and / or reports the predicted beam ID.

[0154] Optionally, when the functionality information included in the first CSI reporting configuration indicates that the first CSI reporting configuration is CSI reporting based on model inference, and / or the model information indicates that the output of the model includes the beam ID and the L1-RSRP, the predicted beam ID and the predicted L1-RSRP corresponding to the predicted beam ID are reported.

[0155] The above methods may (implicitly) determine the content included in the corresponding reported CSI through the functionality information and / or the model information included in the first CSI reporting configuration, avoiding using additional information to indicate the content in the reported CSI, thus reducing information bits of the indication and improving the efficiency of the communication system.

[0156] Methods for the UE to determine the CSI report based on the functionality information and / or the model information included in the first CSI reporting configuration and the first information for enabling or disabling the L1-RSRP reporting will be explained below.

[0157] The UE receives the first CSI reporting configuration (e.g., CSI-ReportConfig). The first CSI reporting configuration includes / corresponds to the functionality information and / or the model information and / or the first information. For example, the first information may be used to enable or disable the predicted L1-RSRP.

[0158] Optionally, when the functionality information included in the first CSI reporting configuration indicates downlink beam prediction and / or model inference and the first information indicates that the (predicted) L1-RSRP is disabled, the UE determines and / or reports the predicted beam ID.

[0159] Optionally, when the functionality information included in the first CSI reporting configuration indicates downlink beam prediction and / or model inference and the first information is not configured, the UE determines and / or reports the predicted beam ID.

[0160] Optionally, when the functionality information included in the first CSI reporting configuration indicates downlink beam prediction and / or model inference and the first information indicates that the (predicted) L1-RSRP is enabled, the UE determines and / or reports the predicted beam ID and the predicted L1-RSRP (corresponding to the predicted beam ID).

[0161] The above methods may determine the content included in the corresponding reported CSI according to the functionality information and / or the model information and the first information included in the first CSI reporting configuration, thereby flexibly indicating the content in the reported CSI and improving the flexibility of the communication system.

[0162] Methods for the UE to determine the CSI report based on the report quantity parameter and the first information for enabling or disabling the L1-RSRP reporting included in the first CSI reporting configuration will be explained below.

[0163] The UE receives the first CSI reporting configuration (e.g., CSI-ReportConfig). The first CSI reporting configuration includes the report quantity parameter (for example, reportQuantity) and / or the first information and / or the time information. For example, the first information is used to enable or disable the L1-RSRP. For example, the first information may be used to enable or disable the predicted L1-RSRP. The time information is described later.

[0164] The UE reports the predicted beam ID or the predicted L1-RSRP corresponding to the predicted beam ID based on the report quantity parameter and / or the first information and / or the time information included in / corresponding to the first CSI reporting configuration.

[0165] When the report quantity parameter included in the first CSI reporting configuration is set to ‘cri-RSRP’ and the first information indicates that the (predicted) L1-RSRP is enabled (and the first CSI reporting configuration includes the time information), the UE determines and / or reports the CSI corresponding to the first CSI reporting configuration, wherein the CSI includes the predicted CRI and the predicted L1-RSRP (corresponding to the predicted CRI). In this application, the term “the report quantity parameter includes CRI” may be replaced by “the report quantity parameter is set to ‘cri-RSRP’”. Optionally, when the report quantity parameter includes CRI, the beam ID in the reported CSI corresponding to the first CSI reporting configuration is CRI.

[0166] When the report quantity parameter included in the first CSI reporting configuration is set to ‘cri-RSRP’ and the first CSI reporting configuration does not include the first information (and the first CSI reporting configuration includes the time information), or the first information included in the first CSI reporting configuration indicates that the (predicted) L1-RSRP is disabled (and the first CSI reporting configuration includes the time information), the UE determines and / or reports the CSI corresponding to the first CSI reporting configuration.

[0167] When the report quantity parameter included in the first CSI reporting configuration is set to ‘ssb-Index-RSRP’ and the first information indicates that the (predicted) L1-RSRP is enabled (and the first CSI reporting configuration includes the time information), the UE determines and / or reports the CSI corresponding to the first CSI reporting configuration, wherein the CSI includes the predicted CRI and the predicted L1-RSRP (corresponding to the predicted beam ID). In this application, the term ‘the report quantity parameter includes SSBRI’ may be replaced by ‘the report quantity parameter is set to ‘ssb-Index-RSRP’”. Optionally, when the report quantity parameter includes SSBRI, the beam ID in the reported CSI corresponding to the first CSI reporting configuration is SSBRI.

[0168] When the report quantity parameter includes CRI, the beam ID is CRI (CSI-RS resource indicator).

[0169] When the first CSI reporting configuration includes the report quantity parameter set to ‘ssb-Index-RSRP’ and does not include the first information, or the first information included in the first CSI reporting configuration indicates that the (predicted) L1-RSRP is disabled (and the first CSI reporting configuration includes the time information), the UE determines and / or reports the CSI corresponding to the first CSI reporting configuration, wherein the CSI includes the predicted SSBRI.

[0170] When the first CSI reporting configuration includes the report quantity parameter set to ‘ssb-Index-RSRP’ or set to ‘cri-RSRP’ and the first CSI reporting configuration includes the first information (and the first CSI reporting configuration includes the time information), the UE may be assumed to support downlink transmission beam prediction.

[0171] When the first CSI reporting configuration includes the report quantity parameter set to ‘ssb-Index-RSRP’ or ‘cri-RSRP’ and the first CSI reporting configuration includes the first information (and the first CSI reporting configuration includes the time information), the UE determines / assumes that the first CSI reporting configuration is for downlink transmission beam prediction.

[0172] When the first CSI reporting configuration includes the report quantity parameter set to ‘ssb-Index-RSRP’ or ‘cri-RSRP’ and the first CSI reporting configuration includes the first information (and the first CSI reporting configuration includes the time information), the UE determines / assumes that the first CSI reporting configuration may be for time domain downlink transmission beam prediction, or the UE determines / assumes that the first CSI reporting configuration is for time domain downlink transmission beam prediction, or the UE determines / assumes that the first CSI reporting configuration includes the time information. For example, a predicted beam ID (e.g., CRI or SSBRI) and / or a corresponding predicted L1-RSRP are associated with one or more time intervals. Here, the one or more time intervals may be determined based on the time information. Refer below for further explanation of the time interval and the time information.

[0173] The above methods may determine the content included in the corresponding reported CSI and / or the prediction type (for example, time domain downlink transmission beam prediction) corresponding to the reported CSI according to the report quantity and / or the first information included in the first CSI reporting configuration, avoiding using additional information to indicate the content in the reported CSI, thereby reducing information bits of the indication and improving the efficiency of the communication system.

[0174] In the above methods, it is introduced how the UE determines and / or reports the CSI (the predicted beam ID and / or the predicted L1-RSRP) based on at least one of the report quantity parameter, the functionality information and / or the model information, the spatial information, the time information and the first information for enabling or disabling the L1-RSRP reporting included in the first CSI reporting configuration. For model inference of the UE-side AI / ML model, since total calculating resources of the UE are limited, it is necessary to specify / determine the calculating resources required by the UE during the model inference, so that the base station may reasonably allocate the calculating resources of the UE. In this application, “calculating resources” may be replaced by at least one of “computing power”, “computing capacity”, “occupied calculating resources”, “consumed calculating resources”, “CSI calculating resources”, “resources for the AI / ML”, “parallel calculating resources for the AI / ML”, “calculating resources and / or storage resources for the AI / ML”, “CSI processing unit (CPU)” and “a number of occupied CPUs”. The method for determining the number (for example, ) of the occupied CPUs corresponding to the first CSI reporting configuration described above will be described below taking CPU as an example. The following briefly describes relevant definition of .

[0175] The UE indicates the number of supported simultaneous CSI calculationsNCPUwith parameter simultaneousCSI-ReportsPerCC in a component carrier, and simultaneousCSI-ReportsAllCC across all component carriers.

[0176] The UE supporting parallel CSI calculations means that the UE has CSI processing units (CPUs) for processing CSI reports. If a UE supports imultaneous CSI calculations it is said to have CSI processing units for processing CSI reports. If L CPUs are occupied for calculation of CSI reports in a given OFDM symbol, the UE has unoccupied CPUs.

[0177] If N CSI reports start occupying their respective CPUs on the same OFDM symbol on which CPUs are unoccupied, where each CSI report corresponds to , the UE is not required to update the requested CSI reports with lowest priority, where is the largest value such that holds. Processing of a CSI report (e.g., the CSI report corresponding to the first CSI reporting configuration described above) occupies a number of CPUs for a number of symbols.

[0178] The number ( ) of the occupied CPU corresponding to / associated with the first CSI reporting configuration described above is determined based on at least one of the followings:

[0179] ● the report quantity corresponding to the first CSI reporting configuration;

[0180] ● the functionality information and / or the model information included in the first CSI reporting configuration;

[0181] ● the spatial information included in the first CSI reporting configuration;

[0182] ● the time information included in the first CSI reporting configuration;

[0183] ● the first information included in the first CSI reporting configuration;

[0184] ● a resource type of the resource set associated with the first CSI reporting configuration; the resource type is, for example, one of periodic, semi-persistent and aperiodic;

[0185] ● the UE capability signaling;

[0186] ● the number of resource sets associated with the first CSI reporting configuration;

[0187] ● the number of resources in the resource set associated with the first CSI reporting configuration;

[0188] ● the number of the predicted beam IDs;

[0189] ● the number of the predicted L1-RSRPs.

[0190] Optionally, when the first CSI reporting configuration includes the functionality information and / or the model information, the number of the occupied CPUs associated with the first CSI reporting configuration is determined based on the functionality information and / or the model information and / or the UE capability signaling. For example, when the first CSI reporting configuration includes the functionality information and / or the model information, the number of the occupied CPUs associated with the first CSI reporting configuration is indicated by the functionality information and / or the model information. For example, when the first CSI reporting configuration includes the functionality information and / or the model information, the number of the occupied CPUs associated with the first CSI reporting configuration is determined by the number of the occupied CPUs corresponding to the functionality information and / or the model information. The mapping relationship between the functionality information and / or the model information and the number of the occupied CPUs is predefined or indicated by the UE capability signaling.

[0191] Optionally, when the first CSI reporting configuration includes the spatial information, the number of the occupied CPUs associated with the first CSI reporting configuration is determined based on the spatial information. For example, when the first CSI reporting configuration includes the spatial information, the number of the occupied CPUs associated with the first CSI reporting configuration is determined based on the beam ID set determined by the spatial information and / or the resource set for measurement associated with the first CSI reporting configuration and / or the UE capability signaling. Here, the method for determining the beam ID set through the spatial information is explained above. For example, when the first CSI reporting configuration includes the spatial information, the number of the occupied CPUs associated with the first CSI reporting configuration is determined based on the number of the beam IDs in the beam ID set determined by the spatial information and / or the number of the measurement resources in the resource set for measurement associated with the first CSI reporting configuration and / or the UE capability signaling. For example, when the first CSI reporting configuration includes the spatial information, the number of the occupied CPUs associated with the first CSI reporting configuration is determined based on the product / sum of the number of the beam IDs in the beam ID set determined by the spatial information and / or the number of the measurement resources in the resource set for measurement associated with the first CSI reporting configuration and / or a parameter indicated by the UE capability signaling. The beam ID set may correspond to the output of the AI / ML model, and the resource set for measurement may correspond to the input of the AI / ML model. The number of the beam IDs in the beam ID set may correspond to the number of outputs of the AI / ML model, and the number of the measurement resources in the resource set for measurement may correspond to the number of inputs of the AI / ML model. If the inputs and / or outputs of the model change, the architecture of the model itself may change, so the resources occupied by model inference (that is, ) may also change. Therefore, the number of the occupied CPUs is determined based on (the number of the beam IDs in) the beam ID set determined by the spatial information and / or (the number of the measurement resources in) the resource set for measurement associated with the first CSI reporting configuration, which may reflect the above relationship more precisely, avoid unclarity of the number of the occupied CPUs and improve the reliability of the communication system.

[0192] Optionally, when the first CSI reporting configuration includes the time information, the number of the occupied CPUs associated with the first CSI reporting configuration is determined based on the time information and / or the UE capability signaling. Optionally, when the first CSI reporting configuration includes the time information, the number of the occupied CPUs associated with the first CSI reporting configuration is determined based on the number of the one or more time intervals determined by the time information and / or the number of the one or more measurement windows determined by the time information and / or the UE capability signaling. Optionally, when the first CSI reporting configuration includes the time information and the associated resource set for measurement corresponding to the first CSI reporting configuration is periodic or semi-persistent, the number of the occupied CPUs associated with the first CSI reporting configuration is determined based on the number of the one or more time intervals determined by the time information and / or the number of the one or more measurement windows determined by the time information and / or the UE capability signaling. With the increasing number of the measurement windows or time intervals, the corresponding AI / ML model may become more complicated, therefore, the number of the occupied CPU is determined based on the number of the one or more time intervals and / or the number of the one or more measurement windows determined by the time information, which may reflect the above relationship more precisely, avoid unclarity of the number of the occupied CPUs and improve the reliability of the communication system.

[0193] Optionally, when the first CSI reporting configuration includes the time information, the number of the occupied CPUs associated with the first CSI reporting configuration is determined based on the time information and / or the UE capability signaling. Optionally, when the first CSI reporting configuration includes the time information, the number of the occupied CPUs associated with the first CSI reporting configuration is determined based on the number of the one or more measurement occasions determined by the time information and / or the UE capability signaling. Optionally, when the first CSI reporting configuration includes the time information and the associated resource set for measurement corresponding to the first CSI reporting configuration is periodic or semi-persistent, the number of the occupied CPUs associated with the first CSI reporting configuration is determined based on the number of the one or more measurement occasions determined by the time information and / or the UE capability signaling. With the increasing number of the measurement occasions for determining the CSI report, the corresponding AI / ML model may be more complicated, therefore, the number of the occupied CPU is determined based on the number of the one or more time intervals and / or the number of the one or more measurement windows determined by the time information, which may reflect the above relationship more precisely, avoid unclarity of the number of the occupied CPUs and improve the reliability of the communication system.

[0194] Optionally, when the first CSI reporting configuration includes the time information, the number of the occupied CPUs associated with the first CSI reporting configuration is determined based on the resource set for measurement associated with the first CSI reporting configuration and / or the UE capability signaling. Optionally, when the first CSI reporting configuration includes the time information, the number of the occupied CPUs associated with the first CSI reporting configuration is determined based on the number of the resources in the resource set associated with the first CSI reporting configuration and / or the UE capability signaling. For example, when the first CSI reporting configuration includes the time information, the number of the occupied CPUs associated with the first CSI reporting configuration is determined based on the product of the number of the resource set for measurements associated with the first CSI reporting configuration and the parameter indicated by the UE capability signaling. For example, when the first CSI reporting configuration includes the time information and the resource set for measurement associated with the first CSI reporting configuration is aperiodic, the number of the occupied CPUs associated with the first CSI reporting configuration may be determined based on the number of the resource set for measurements associated with the first CSI reporting configuration and / or the UE capability signaling. For example, when the first CSI reporting configuration includes the time information and the resource set for measurement associated with the first CSI reporting configuration is aperiodic, the number of the occupied CPUs associated with the first CSI reporting configuration may be determined based on the product / sum of the number of the resource set for measurements associated with the first CSI reporting configuration and the parameter indicated by the UE capability signaling. Optionally, for the aperiodic resource set for measurement, the more the measurement resources in the resource set for measurement, the greater the input of the AI / ML model, which makes the corresponding AI / ML model more complex and thus occupies more CPUs. Therefore, the number of the occupied CPUs may be determined based on the number of the resource set for measurements associated with the first CSI reporting configuration, which may well reflect this characteristic, avoid unclarity of the number of the occupied CPUs and improve the reliability of the communication system.

[0195] Optionally, the number of the occupied CPUs associated with the first CSI reporting configuration is determined based on whether the predicted L1-RSRP is included in the CSI associated with / corresponding to the first CSI reporting configuration. For example, when the CSI associated with / corresponding to the first CSI reporting configuration does not include the predicted L1-RSRP, the number of the occupied CPUs associated with the first CSI reporting configuration is X1. For example, when the CSI associated with / corresponding to the first CSI reporting configuration includes the predicted L1-RSRP, the number of the occupied CPUs associated with the first CSI reporting configuration is X2 (X2 ≥ X1). The case where the CSI associated with / corresponding to the first CSI reporting configuration only includes the predicted beam ID and the case where the CSI associated with / corresponding to the first CSI reporting configuration includes the predicted beam ID and the predicted L1-RSRP may correspond to different models, and different models will occupy different CPUs, thus the number of the occupied CPUs associated with the first CSI reporting configuration is determined based on whether the CSI associated with / corresponding to the first CSI reporting configuration includes the predicted L1-RSRP, which may reflect the above characteristics, thus avoiding the unclarity of the number of the occupied CPUs and improving the reliability of the communication system.

[0196] For the UE-side AI / ML model, its associated reference signals may be measured through the first CSI reporting configuration for data collection (for example, data collection for the AI / ML). For example, these reference signals are measured and corresponding measurement results are data collected. Since data collection only occurs at UE-side, the UE does not need to give feedback to the network equipment. The following method clarifies that the CSI report does not need to be fed back to the base station by specifying configuration parameters. Optionally, the first CSI reporting configuration satisfies a second condition. Optionally, the second condition may include at least one of the followings:

[0197] ● The first CSI reporting configuration is configured not to report the CSI (e.g., not to report CSI quantity), for example, CSI-ReportConfig with higher layer parameter reportQuantity set to ‘none’;

[0198] ● The first CSI reporting configuration is configured for data collection, for example, the first CSI reporting configuration is configured with a parameter indicating that the CSI reporting configuration is used for data collection. Optionally, when the first CSI reporting configuration is configured with the parameter (either configured for data collection or configured for UE-side data collection), the first CSI reporting does not report the CSI.

[0199] For the UE-side AI / ML model, the CSI report (for example, the first CSI reporting configuration) can be used for data collection for beam management, so the reference signal resources corresponding to the CSI report are used for beam management. The following method clarifies that the corresponding reference signal resources are used for beam management by specifying the configuration parameters. Optionally, the first CSI reporting configuration satisfies a third condition. Optionally, the third condition may include at least one of the followings:

[0200] ● The CSI-RS resources corresponding to the first CSI reporting configuration are not TRS. For example, the CSI-RS resource set parameter (for example, CSI-RS-ResourceSet or NZP-CSI-RS-ResourceSet) corresponding to the first CSI reporting configuration is not configured with TRS information parameter (with higher layer parameter trs-info not configured);

[0201] ● The CSI-RS resources corresponding to the first CSI reporting configuration are used for beam management. For example, the CSI-RS resource set parameter (e.g., CSI-RS-ResourceSet or NZP-CSI-RS-ResourceSet) corresponding to the first CSI reporting configuration is configured with a repetition parameter (with higher layer parameter repetition configured);

[0202] ● The CSI-RS resource set corresponding to the first CSI reporting configuration is configured with the repetition parameter, and the repetition parameter is configured as ‘on’. For example, the repetition parameter of the CSI-RS resource set parameter (e.g., CSI-RS-ResourceSet or NZP-CSI-RS-ResourceSet) corresponding to the first CSI reporting configuration is set to ‘off’' (with higher layer parameter repetition set to ‘off’);

[0203] ● The CSI-RS resource set corresponding to the first CSI reporting configuration is configured with the repetition parameter, and the repetition parameter is configured as ‘on’. For example, the repetition parameter of the CSI-RS resource set parameter (for example, CSI-RS-ResourceSet or NZP-CSI-RS-ResourceSet) corresponding to the CSI report is set to ‘on’ (with higher layer parameter repetition set to ‘on’);

[0204] ● The first CSI reporting configuration is configured with the SSB resource set; for example, the first CSI reporting configuration is configured with a SSB resource set parameter (for example, CSI-SSB-resourceset);

[0205] ● The first CSI reporting configuration is configured to report the L1-RSRP. For example, the report quantity parameter (for example, reportQuantity) of the CSI reporting configuration parameter (for example, CSI-ReportConfig) of the CSI report is set to ‘cri-RSRP’ or ‘SSB-index-RSRP’ (CSI-ReportConfig with higher layer parameter reportQuantity set to ‘cri-RSRP’ or ‘ssb-Index-RSRP’).

[0206] For the UE-side AI / ML model, the CSI report (for example, the CSI reporting configuration) may be further used for data collection for CSI acquisition, so the reference signal resources corresponding to the CSI report are used for CSI acquisition. The following method clarifies that the corresponding reference signal resources are used for CSI acquisition by specifying the configuration parameters. Optionally, the first CSI reporting configuration satisfies a fourth condition. Optionally, the fourth condition may include at least one of the followings:

[0207] ● The CSI-RS resources corresponding to the first CSI reporting configuration are not TRS. For example, the CSI-RS resource set parameter (for example, CSI-RS-ResourceSet or NZP-CSI-RS-ResourceSet) corresponding to the CSI reporting configuration is not configured with the TRS information parameter (with higher layer parameter trs-Info not configured);

[0208] ● The CSI-RS resources corresponding to the first CSI reporting configuration are used for CSI acquisition. For example, the CSI-RS resource set parameter (e.g., CSI-RS-ResourceSet or NZP-CSI-RS-ResourceSet) corresponding to the CSI reporting configuration is not configured with the repetition parameter (with higher layer parameter repetition not configured), and / or the CSI-RS resource set parameter corresponding to the CSI reporting configuration is not configured with the TRS information parameter.

[0209] For the UE-side AI / ML model, the CSI report (for example, the first CSI reporting configuration) may be used for data collection. The UE and the network equipment need to have common understanding of the usage of the CSI report in order to perform corresponding operations. The following method clarifies the usage of the CSI report (for example, suitable for data collection related to beam management). Optionally, the first CSI reporting configuration satisfies a fifth condition. Optionally, the fifth condition may include at least one of the followings:

[0210] ● The first CSI reporting configuration is configured with a first reference signal resource set (for channel measurement) and / or a second reference signal resource set (for channel measurement); wherein the first reference signal resource set is the CSI-RS resource set, and the second reference signal resource set is the SSB resource set;

[0211] ● The usage of the first CSI reporting configuration is indicated as data collection. For example, the base station indicates that the usage of the first CSI reporting configuration is data collection through at least one of DCI, MAC-CE and RRC signaling. Optionally, the data collection may be UE-side data collection.

[0212] Optionally, the first CSI reporting configuration is used for data collection. For example, the base station indicates that the first CSI reporting configuration is for data collection through at least one of DCI, MAC-CE and RRC signaling. Optionally, the data collection may be UE-side data collection.

[0213] Optionally, when the first CSI reporting configuration satisfies at least one of the second condition, the third condition, the fourth condition and the fifth condition, the determination method for corresponding to the first CSI reporting configuration is at least one of the following methods:

[0214] ● Method 1: corresponding to the first CSI reporting configuration is predefined. For example, is equal to one of 0, 1, 0.5, 2 / 3, 2, 3, 4, 5, 6, 7 and 8.

[0215] ● Method 2: corresponding to the first CSI reporting configuration is determined based on the UE capability signaling. For example, is indicated by the UE capability signaling. Optionally, the value of the UE capability signaling is one of 0, 1, 0.5, 2 / 3, 2, 3, 4, 5, 6, 7 and 8.

[0216] ● Method 3: corresponding to the first CSI reporting configuration is determined based on the resource set corresponding to / associated with the first CSI reporting configuration including the mapping relationship / association between the first set and the second set.

[0217] ■ For example, if the resource set corresponding to the first CSI reporting configuration includes the first resource set and / or the second resource set, and the second resource set corresponding to the first CSI reporting configuration is a subset of the first resource set, corresponding to the first CSI reporting configuration is a specific value (for example, one of 0, 1, 2 and 3, or 0).

[0218] ■ For example, if the resource set corresponding to / associated with the first CSI reporting configuration includes the first resource set and the second resource set, and the second resource set corresponding to the first CSI reporting configuration is not a subset of the first resource set, corresponding to the first CSI reporting configuration is a specific value (for example, one of 0, 1, 2 and 3, or 1);

[0219] ■ For example, if the resource set corresponding to / associated with the first CSI reporting configuration includes the first resource set and the second resource set, and the first resource set corresponding to / associated with the first CSI reporting configuration is the CSI-RS resource set, and the second resource set corresponding to / associated with the first CSI reporting configuration is the SSB resource set, corresponding to the first CSI reporting configuration is a specific value (for example, one of 0, 1, 2 and 3, or 1).

[0220] ■ Method 4: corresponding to the first CSI reporting configuration is determined based on the indication of the base station. For example, the base station explicitly indicates corresponding to the first CSI reporting configuration through at least one of DCI, MAC-CE and RRC signaling.

[0221] ■ Method 5: corresponding to the first CSI reporting configuration is determined based on the functionality information and / or the model information included in the first CSI reporting configuration. For example, when the first CSI reporting configuration includes the functionality information and the functionality information corresponds to the spatial domain downlink transmission beam prediction, is a specific value . may be predefined (for example, one of 0, 1, 2, 3, 4) or determined based on the UE capability indication. For example, when the first CSI reporting configuration includes the functionality information and the functionality information corresponds to the spatial domain downlink transmission beam prediction, is a specific value. For example, the specific value is one of 0, 1, 2, 3, 4, . may be predefined (for example, one of 0, 1, 2, 3, 4) or determined based on the UE capability indication. NABC may be predefined (for example, one of 0, 1, 2, 3 and 4) or determined based on the UE capability signaling indication.

[0222] Optionally, when the first CSI reporting configuration satisfies the second condition and / or the third condition, the value of corresponding to the first CSI reporting configuration is 0 (for example, = 0). When the first CSI reporting configuration satisfies the second condition and / or the third condition, it may be assumed that the first CSI reporting configuration is used for data collection. Since CSI calculation is unnecessary for data collection, the value being 0 may prevent the first CSI reporting configuration from occupying CPU calculating resources, reduce the use of calculating resources and improve the efficiency of the communication system.

[0223] The above provides the method for the occupied CPUs corresponding to the first CSI reporting configuration. The method enables the base station and the UE to have common understanding of the number of the occupied CPUs corresponding to the first CSI reporting configuration (for example, the first CSI reporting configuration for data collection at UE-side), so as to prevent the UE from mistakenly discarding CSI reports due to incorrect determination of the number of the occupied CPUs, and improve the stability of the communication system.

[0224] A symbol of the occupied CPUs corresponding to / associated with the first CSI reporting configuration described above is determined based on at least one of the followings:

[0225] ● the last symbol of the PUSCH / PUCCH carrying the report;

[0226] ● no later than Y1 (Y1≥1) latest consecutive periodic / semi-persistent reference signal occasions of the CSI reference resources; the reference signals are CSI-RS and / or SSB;

[0227] ● the type of the corresponding CSI report.

[0228] Here, the type of the CSI report may be periodic CSI report, semi-persistent CSI report and aperiodic CSI report.

[0229] For a CSI report with CSI-ReportConfig with higher layer parameter reportQuantity not set to ‘none’, the CPU(s) are occupied for a number of OFDM symbols as follows. If the report corresponding to the first CSI reporting configuration is a periodic CSI report or a semi-persistent CSI report, the CPU(s) occupied by the CSI report is from the first symbol of Y1-th latest consecutive CSI-RS occasions or from the first symbol of Y1-th latest consecutive SSB occasion no later than CSI reference resource, until the last symbol of the PUSCH / PUCCH carrying the report. Optionally, the CSI-RS occasion is periodic or semi-persistent. Optionally, Y1 ≥ 1. Optionally, Y1 is configured by the base station. For example, Y1 is configured in the first CSI reporting configuration. Optionally, Y1 is predefined, for example, one of 1, 2, 3 and 4. Optionally, Y1 is based on the UE capability. For example, Y1 is indicated by the UE capability signaling.

[0230] In the above methods, it is introduced how the UE determines and / or reports the CSI (the predicted beam ID and / or the predicted L1-RSRP) based on at least one of the report quantity parameter, the functionality information and / or the model information, the spatial information, the time information and the information for enabling or disabling the L1-RSRP reporting included in the first CSI reporting configuration. When the resource set for measurement associated with / corresponding to the first CSI reporting configuration is aperiodic, and the CSI report corresponding to the first CSI reporting configuration is aperiodic, the DCI format triggering the CSI report, the triggered measurement resources, and the PUSCH carrying the CSI report need to satisfy CSI calculation delay requirements. The following describes a method for determining CSI computation time associated with the first CSI reporting configuration. In this application, the term “CSI computation time” may be used interchangeably with the term “CSI calculation delay requirement” or “Z timeline”. The definition of the CSI computation time is briefly explained below.

[0231] The UE may receive downlink control information (DCI). Optionally, the DCI triggers the aperiodic report. Optionally, the DCI (or the CSI request field contained in the DCI) may trigger one or more CSI reports (on physical uplink shared channel (PUSCH)). For example, the one or more CSI reports are carried by the PUSCH. Optionally, the one or more CSI reports include (a) first CSI report.

[0232] Optionally, the one or more CSI reports include / correspond to a first CSI report. For example, the first CSI report represents the n-th (triggered) report in the one or more reports.

[0233] Optionally, the UE determines / feedbacks / reports the first CSI report (or the UE provides a (valid) CSI report for the first CSI report). Optionally, the UE determines / feedbacks / reports the first CSI report (or the UE provides a (valid) CSI report for the first CSI report) when at least one of the following conditions is satisfied:

[0234] ● The time unit carrying the one or more CSI reports is no earlier than a first time unit. For example, the unit of the time unit may be a slot or a symbol. For example, the time unit carrying the one or more CSI reports may be the first uplink symbol carrying the one or more CSI reports. Optionally, the uplink symbol includes (or needs to consider) the effect of the timing advance. Refer below for description of the first time unit (e.g., );

[0235] ● The time unit carrying the first CSI report is no earlier than a second time unit. For example, the unit of the time unit may be a slot or a symbol. For example, the time unit carrying the first CSI report may be the first uplink symbol carrying the first CSI report. Optionally, the uplink symbol includes (or needs to consider) the effect of the timing advance. Refer below for description of the second time unit.

[0236] Optionally, the first time unit (e.g., ) is determined based on the time unit where the physical downlink control channel (PDCCH) corresponding to the DCI (e.g., the DCI triggering the one or more CSI reports) is located and the CSI calculation delay parameter corresponding to one (or each) CSI report of the one or more CSI reports. Optionally, the first time unit may be an uplink symbol (for example, the next uplink symbol) (after a first specific time) after the last symbol where the PDCCH corresponding to the DCI (for example, the DCI triggering the one or more CSI reports) is located. Optionally, the first specific time is determined based on the CSI calculation delay parameter corresponding to one (or each) CSI report of the one or more CSI reports. For example, is defined as the next uplink symbol with its CP starting after the end of the last symbol of the PDCCH triggering the CSI report(s). Here, Refer to description of Table 1 below for description of the parameter μ. represents the basic time unit for NR. represents the ratio between and . represents the basic time unit for LTE. is a parameter used to indicate the uplink switching time gap. For example, is equal to the switching gap duration or 0. Z represents / equals to the maximum value of the CSI calculation delay parameter corresponding to each CSI report in the updated CSI reports (in the one or more CSI reports). Optionally, the updated CSI report(s) in the one or more CSI reports are determined according to CSI processing criteria (e.g., rules related to the CSI processing unit (CPU)). For example, the terminal device may determine which CSI reports need to be updated and which CSI reports are not required to be updated based on the total number of CSI processing units (CPUs) and the number of the occupied CPUs. Optionally, the updated reports are represented as report 0, report 1, …, report M-1, where the number of the updated reports is M. Optionally, each report may correspond to a CSI calculation delay parameter. For example, the CSI calculation delay parameter corresponding to report m is , .

[0237] Optionally, the second time unit (for example, ) is determined based on the time unit of the measurement resource corresponding to the first CSI report and the CSI calculation delay parameter corresponding to the first CSI report. Optionally, the measurement resources include resources for channel measurement and / or resources for interference measurement. Optionally, the measurement resources may be aperiodic resources. Optionally, the measurement resource corresponding to the first CSI report may be the latest resource in the measurement resources. For example, in the case that there are a plurality of measurement resources corresponding to the first CSI report, the measurement resource corresponding to the first CSI report refers to the latest resource (in time domain) in the measurement resources used for the first CSI report. For example, the time unit of the measurement resource corresponding to the first CSI report refers to the last symbol of the latest resource (in time domain) in the measurement resources used for the first CSI report. Optionally, the second time unit may be an uplink symbol (after a second specific time) after the last symbol of the latest resource in the measurement resources for the first CSI report. Optionally, the second specific time is determined based on the CSI calculation delay parameter corresponding to one (or each) CSI report of the one or more CSI reports. For example, taking the first CSI report as an example, is defined as the next uplink symbol with its CP starting after the end of the last symbol in time of the latest of: aperiodic CSI-RS resource for channel measurements, aperiodic CSI-IM used for interference measurements, and aperiodic NZP CSI-RS for interference measurement, when aperiodic CSI-RS is used for channel measurement for the first CSI report. Here, Refer to description of Table 1 below for description of the parameter μ. represents the basic time unit for NR. represents the ratio between and . represents the basic time unit for LTE. represents the maximum value of the CSI calculation delay parameter corresponding to each CSI report in the updated CSI reports (in the one or more CSI reports). Optionally, the updated CSI report(s) in the one or more CSI reports are determined according to CSI processing criteria (e.g., rules related to the CSI processing unit (CPU)). For example, the terminal device may determine which CSI reports need to be updated and which CSI reports are not required to be updated based on the total number of CSI processing units (CPUs) and the number of the occupied CPUs. Optionally, the updated reports are represented as report 0, report 1, …, report M-1, where the number of the updated reports is M. Optionally, each report may correspond to a CSI calculation delay parameter. For example, the CSI calculation delay parameter corresponding to report m is , .

[0238] Optionally, the UE may receive DCI. Optionally, the DCI triggers aperiodic report. Optionally, the DCI (or the CSI request field contained in the DCI) may trigger the one or more CSI reports (on the PUSCH).

[0239] Optionally, when the time unit carrying the one or more CSI reports is earlier than the first time unit, the UE ignores the DCI (or scheduling DCI). For example, the DCI is the DCI triggering the one or more CSI reports. Optionally, the time unit carrying the one or more CSI reports includes (or needs to consider) the effect of the timing advance. Here, refer to above description for the first time unit.

[0240] Optionally, when (the starting of) the time unit carrying the first CSI report is earlier than the second time unit, the UE performs at least one of the following operations:

[0241] ● if there is no hybrid automatic repeat request-acknowledgement (HARQ-ACK) or a transport block is multiplexed on the PUSCH and the number of the reported CSI report(s) is 1, the UE ignores the DCI (or scheduling the DCI);

[0242] ● otherwise, the UE is not required to update the first CSI report.

[0243] Optionally, the time unit carrying the first CSI report includes (or needs to consider) the effect of the timing advance. Here, refer to above description for the second time unit.

[0244] For example, may be represented by the following Table 1. Here, μ in Table 1 corresponds to the minimum value of and . Here, corresponds to the subcarrier spacing of the physical downlink control channel (PDCCH) where the DCI (for example, the DCI triggering the CSI report) is carried / transmitted. corresponds to the subcarrier spacing of the PUSCH where the CSI report is carried / transmitted. corresponds to the smallest / largest subcarrier spacing in aperiodic CSI-RS triggered by the DCI. Optionally, the aperiodic CSI-RS triggered by the DCI refers to the resource(s) (e.g., CSI-RS resource(s)) indicated by (all) the sub-configuration(s) triggered by the DCI. In addition, is determined based on the capability parameter (for example, beamReportTiming) reported by the UE. KBl is determined based on the capability parameter (for example, beamSwitchTiming) reported by the UE.

[0245] Table 1

[0246]

[0247] Methods for determining the CSI computation time (for example, ) corresponding to the first CSI reporting configuration is described below, taking the first CSI reporting configuration corresponding to report m as an example.

[0248] In this application, may be used interchangeably with terms “first CSI computation time” or “first CSI calculation delay parameter” or “first CSI computation time corresponding to report m” or “CSI calculation delay parameter associated with the first time unit corresponding to report m” or “CSI calculation delay parameter associated with the first time unit”.

[0249] In this application, may be used interchangeably with terms “second CSI computation time” or “second CSI calculation delay parameter” or “second CSI computation time corresponding to report m” or “CSI calculation delay parameter associated with the second time unit corresponding to report m” or “CSI calculation delay parameter associated with the second time unit”.

[0250] When the first CSI reporting configuration corresponding to report m is the first CSI reporting configuration, the CSI calculation delay parameter corresponding to report m, or the CSI calculation delay parameter associated with the first time unit corresponding to report m, or the first CSI computation time corresponding to report m is determined based on at least one of the followings:

[0251] ● ;

[0252] ● ;

[0253] ● the functionality information and / or the model information included in the first CSI reporting configuration;

[0254] ● the number of resource sets associated with first CSI reporting configuration;

[0255] ● the number of resources in the resource set associated with first CSI reporting configuration;

[0256] ● the time separation between resources in the resource set associated with first CSI reporting configuration;

[0257] ● the periodicity corresponding to the resources in the resource set associated with first CSI reporting configuration;

[0258] ● the resource type of the resource set associated with first CSI reporting configuration; the resource type is, for example, one of periodic, semi-persistent and aperiodic;

[0259] ● the UE capability signaling.

[0260] For beam prediction, because (one or more transmission occasions of) one or more reference signals need to be measured, the CSI computation time needs to consider the time reserved for the measurement window. In addition, due to the increased calculational complexity of beam prediction, the processing time of the CSI report may also increase, so additional processing time may be required. Optionally, the first CSI computation time (for example, ) corresponding to the first CSI reporting configuration may be determined based on or based on and / or W and / or . Optionally, the first CSI computation time (for example, ) orresponding to the first CSI reporting configuration may be determined based on , or based on , or based on the functionality information and / or model information included in the first CSI reporting configuration. Optionally, A may be predefined, or A may be indicated by the UE capability signaling, or A may be indicated by the functionality information and / or model information. Optionally, A may be a positive integer. Optionally, . Optionally, the value of A may be one of 1, 2, 3, 4, 5, 6, 7, 8, 12, 16 and 32. Optionally, A=B. Optionally, A and B may be indicated by the same UE capability parameter. Optionally, A and B may be indicated by different UE capability parameters, respectively. Refer below for description of B. When the resource set for channel measurement corresponding to the first CSI reporting configuration is aperiodic, the first CSI computation time (for example, ) corresponding to the first CSI reporting configuration may be determined based on or based on and / or W and / or . Optionally, W is determined based on at least one of the time separation between resources in the resource set associated with the first CSI reporting configuration and the number of resources in the resource set associated with the first CSI reporting configuration. Optionally, W is the length of the measurement window. Optionally, W refers to the time separation between the first resource and the last resource in the resource set. The unit of W is a symbol. For example, when the first resource in the measurement set is in slot #x and the last resource is in slot #y, W = (x-y) * 14. For example, the aperiodic resource set corresponding to the first CSI reporting configuration corresponds to K groups of resources, respectively, and each group of resources corresponds to resources in P same slots, and K groups are equally spaced in time domain, and the spacing is m. When the unit of m is a slot, for example, W = (K-1) * m * 14. Here, K may be indicated by the base station, predefined (for example, K is 1 or 2), or indicated by the UE capability signaling. Here, m may be indicated by the base station, predefined, or indicated by the UE capability signaling. Optionally, the first CSI computation time (for example, ) corresponding to the first CSI reporting configuration may be determined based on or based on and / or W and / or Y1 and / or . Here, W is the length of the measurement window. When the resource set for channel measurement corresponding to the first CSI reporting configuration is periodic or semi-persistent, W is determined based on the periodicity of the resource set or the periodicity (T) and / or Y1 of the resources in the resource set.

Therefore, the transmission of the first uplink channel and / or the transmission of the second uplink channel may inform the base station that there is a problem with the performance of model inference, so as to facilitate the base station to manage the model later. In addition, because the result of model inference is not accurate, information related to resource measurement may be reported, in order for the base station for beam / resource selection. Optionally, the measurement related information includes information of M resources (for example, CRI / SSBRI corresponding to M resources) and / or L1-RSRPs corresponding to M resources. Optionally, the measurement related information includes information of one or more resources in the third set (for example, CRI / SSBRI corresponding to one or more resources) and / or the (measured) L1-RSRP corresponding to each resource of one or more resources.

Refer to the description of Condition / Event #3 for the description of the difference between the (predicted) probability corresponding to N resources and the second threshold.

[0332] ● Condition / Event #1: M resources (based on measurement) are different from N resources (based on prediction). Optionally, M resources being different from N resources means that the m-th strongest resource in M resources is different from the m-th strongest resource in N resources. Optionally, m may be one of integers ranged from 1 to M. Optionally, m may be any integer ranged from 1 to M. Optionally, M resources being different from N resources means that resources in M resources and (at least one or all of) resources with the same ranking in N resources are different. For example, the first strongest resource in M resources is different from the first strongest resource in N resources, and / or the second strongest resource in M resources is different from the second strongest resource in N resources, and so on. Condition / Event #1 may be used to measure the accuracy of beam prediction. When the better beam predicted by the UE is different from the better beam measured by the UE, the prediction result of the AI / ML model is relatively unreliable. The UE may measure the accuracy of beam prediction based on Condition / Event #1, so as to perform corresponding operations (for example, report to the base station), which facilitates the management of the AI / ML model and improves the performance of the communication system.

[0333] ● Condition / Event #2: the difference between the (measured) L1-RSRP corresponding to M resources (based on measurement) and the (predicted) L1-RSRP corresponding to N resources (based on prediction) is greater than (or equal to) a first threshold. Optionally, the difference between the L1-RSRP corresponding to M resources and the L1-RSRP corresponding to N resources is greater than (or equal to) the first threshold, which means that the difference between the L1-RSRP corresponding to the m-th strongest resource in M resources and the (predicted) L1-RSRP corresponding to the m-th strongest resource in N resources is greater than (or equal to) the first threshold. Optionally, m may be one of integers ranged from 1 to M. Optionally, m may be any integer ranged from 1 to M. Optionally, the difference between the L1-RSRP corresponding to M resources and the L1-RSRP corresponding to N resources is greater than (or equal to) the first threshold, which means that the difference between the L1-RSRP corresponding to resources in M resources and the L1-RSRP corresponding to (at least one or all of) resources with the same ranking in N resources is greater than (or equal to) the first threshold. For example, the difference between the L1-RSRP corresponding to the first strongest resource in M resources and the L1-RSRP corresponding to the first strongest resource in N resources is greater than (or equal to) the first threshold, and / or the difference between the L1-RSRP corresponding to the second strongest resource in M resources and the L1-RSRP corresponding to the second strongest resource in N resources is greater than (or equal to) the first threshold, and so on. Optionally, the first threshold may be predefined, or indicated by the base station (for example, indicated by the base station through at least one of RRC, MAC-CE and DCI), or based on the UE capability. Optionally, the unit corresponding to the first threshold is dB. Condition / Event #2 may be used to measure the accuracy of the predicted L1-RSRP. When the difference between the L1-RSRP of the beam predicted by the UE and the L1-RSRP of the beam measured by the UE is large, it indicates that the prediction result of the AI / ML model is relatively unreliable. The UE may measure the accuracy of the predicted L1-RSRP based on the Condition / Event #2, so as to perform corresponding operations (for example, report to the base station), which facilitates the management of the AI / ML model and improves the performance of the communication system. Optionally, Condition / Event #2 may be combined with Condition / Event #1. For example, Condition / Event #1 is not triggered / not satisfied, and Condition / Event #2 is triggered / satisfied, and the UE reports / transmits the first uplink channel and / or the second uplink channel. In this case, although M resources are the same as N resources, the difference of the L1-RSRPs corresponding to M resources and N resources is too large, which indicates that the prediction result of the AI / ML model is relatively unreliable.

[0334] ● Condition / Event #3: the (predicted) probability corresponding to N resources (based on prediction) is less than (or equal to) the second threshold. Optionally, the (predicted) probability corresponding to N resources is less than (or equal to) the second threshold, which means that the (predicted) probability corresponding to the strongest resource in N resources is less than (or equal to) the second threshold. Optionally, the (predicted) probability corresponding to N resources is less than (or equal to) the second threshold, which means that the (predicted) probability corresponding to the n-th strongest resource in N resources is less than (or equal to) the second threshold. Optionally, n may be one of integers ranged from 1 to N. Optionally, n may be any integer ranged from 1 to N. Optionally, the (predicted) probability corresponding to N resources is less than (or equal to) the second threshold, which means that the (predicted) probability corresponding to each of N resources is less than (or equal to) the second threshold. Optionally, the second threshold may be predefined, or indicated by the base station (for example, indicated by the base station through at least one of RRC, MAC-CE and DCI), or based on the UE capability. Optionally, the value of the second threshold is greater than or equal to 0. Optionally, the value of the second threshold is less than or equal to 1. Since the value of the probability is generally between 0 and 1, limiting the value range of threshold between 0 and 1 may match the value range of the predicted probability and improve the efficiency of the communication system. Condition / Event #3 may be used to measure the accuracy of prediction. When the probability of the beam predicted by the UE is low, the prediction result of the AI / ML model is relatively unreliable. The UE may measure the accuracy of beam prediction based on Condition / Event #3, so as to perform corresponding operations (for example, report to the base station), which facilitates the management of the AI / ML model and improves the performance of communication system. Optionally, Condition / Event #3 may be combined with Condition / Event #1. For example, Condition / Event #1 is not triggered / not satisfied, and Condition / Event #3 is triggered / satisfied, and the UE reports / transmits the first uplink channel and / or the second uplink channel. In this case, although M resources are the same as N resources, the corresponding probability of N resources is low, which indicates that the prediction result of the AI / ML model is relatively unreliable.

[0335] Optionally, the UE reports / transmits the first uplink channel and / or the second uplink channel. Optionally, the UE reports / transmits the first uplink channel and / or the second uplink channel based on at least one of the following conditions / events (for example, Condition / Event #4, Condition / Event #5 and Condition / Event #6).

Optionally, when at least one of the following conditions / events is satisfied / triggered in a time instance (or, in F time instances, or in F consecutive time instances, or in at least a time instance of F time instances), the UE reports / transmits the first uplink channel and / or the second uplink channel. Optionally, the transmission of the first uplink channel and / or the transmission of the second uplink channel is triggered by at least one of the following events. Optionally, the first uplink channel may be used to inform the base station that the corresponding condition is satisfied / corresponding event is triggered. Optionally, the first uplink channel and / or the second uplink channel may include / report information related to prediction. When at least one of the following conditions / events is satisfied / triggered, the result of the UE-side model inference is relatively accurate, so the transmission of the first uplink channel and / or the transmission of the second uplink channel may inform the base station that the corresponding model inference result may be used, so as to facilitate the base station to manage the model later. In addition, because the result of model inference is relatively accurate, information related to resource prediction may be reported, in order for the base station for beam / resource selection. Optionally, the prediction related information includes information of N resources (for example, CRI / SSBRI corresponding to N resources) and / or the L1-RSRP corresponding to N resources. Optionally, the first uplink channel and / or the second uplink channel may include / report measurement related information. Optionally, the measurement related information includes information of M resources (for example, CRI / SSBRI corresponding to M resources) and / or the L1-RSRP corresponding to M resources. Optionally, the measurement related information includes information of one or more resources in the third set (for example, CRI / SSBRI corresponding to one or more resources) and / or the (measured) L1-RSRP corresponding to each resource of one or more resources. Optionally, the first uplink channel and / or the second uplink channel may indicate / report whether M resources (based on measurement) are the same as N resources (based on prediction). Refer to the description of Condition / Event #4 for the description of whether M resources are the same as N resources. Optionally, the first uplink channel and / or the second uplink channel may indicate / report / include the difference between the L1-RSRP corresponding to M resources (based on measurement) and the L1-RSRP corresponding to N resources (based on prediction). Refer to the description of Condition / Event #5 for the description of the difference between the L1-RSRP corresponding to M resources and L1-RSRP corresponding to N resources. Optionally, the first uplink channel and / or the second uplink channel may indicate / report / include the (predicted) probability corresponding to N resources. Optionally, the first uplink channel and / or the second uplink channel may indicate / report / include the difference between the (predicted) probability corresponding to N resources and the second threshold. Refer to the description of Condition / Event #6 for the description of the difference between the (predicted) probability corresponding to N resources and the second threshold.

[0336] ● Condition / Event #4: M resources (based on measurement) are same as N resources (based on prediction). Optionally, M resources being same as N resources means that the m-th strongest resource in M resources is same as the m-th strongest resource in N resources. Optionally, m may be one of integers ranged from 1 to M. Optionally, m may be any integer ranged from 1 to M. Optionally, M resources being same as N resources means that resources in M resources and (at least one or all of) resources with the same ranking in N resources are different. For example, the first strongest resource in M resources is same as the first strongest resource in N resources, and / or the second strongest resource in M resources is same as the second strongest resource in N resources, and so on. Condition / Event #4 may be used to measure the accuracy of beam prediction. When the better beam predicted by the UE is same as the better beam measured by the UE, the prediction result of the AI / ML model is relatively reliable. The UE may measure the accuracy of beam prediction based on Condition / Event #4, so as to perform corresponding operations (for example, report to the base station), which facilitates the management of the AI / ML model and improves the performance of the communication system.

[0337] ● Condition / Event #5: the difference between the (measured) L1-RSRP corresponding to M resources (based on measurement) and the (predicted) L1-RSRP corresponding to N resources (based on prediction) is less than (or equal to) a first threshold. Optionally, the difference between the L1-RSRP corresponding to M resources and the L1-RSRP corresponding to N resources is less than (or equal to) the first threshold, which means that the difference between the L1-RSRP corresponding to the m-th strongest resource in M resources and the (predicted) L1-RSRP corresponding to the m-th strongest resource in N resources is less than (or equal to) the first threshold. Optionally, m may be one of integers ranged from 1 to M. Optionally, m may be any integer ranged from 1 to M. Optionally, the difference between the L1-RSRP corresponding to M resources and the L1-RSRP corresponding to N resources is less than (or equal to) the first threshold, which means that the difference between the L1-RSRP corresponding to resources in M resources and the L1-RSRP corresponding to (at least one or all of) resources with the same ranking in N resources is less than (or equal to) the first threshold. For example, the difference between the L1-RSRP corresponding to the first strongest resource in M resources and the L1-RSRP corresponding to the first strongest resource in N resources is less than (or equal to) the first threshold, and / or the difference between the L1-RSRP corresponding to the second strongest resource in M resources and the L1-RSRP corresponding to the second strongest resource in N resources is less than (or equal to) the first threshold, and so on. Optionally, the first threshold may be predefined, or indicated by the base station (for example, indicated by the base station through at least one of RRC, MAC-CE and DCI), or based on the UE capability. Optionally, the unit corresponding to the first threshold is dB. Condition / Event #5 may be used to measure the accuracy of the predicted L1-RSRP. When the difference between the L1-RSRP of the beam predicted by the UE and the L1-RSRP of the beam measured by the UE is samll, it indicates that the prediction result of the AI / ML model is relatively reliable. The UE may measure the accuracy of the predicted L1-RSRP based on the Condition / Event #5, so as to perform corresponding operations (for example, report to the base station), which facilitates the management of the AI / ML model and improves the performance of the communication system. Optionally, Condition / Event #5 may be combined with Condition / Event #4. For example, Condition / Event #4 is not triggered / not satisfied, and Condition / Event #5 is triggered / satisfied, and the UE reports / transmits the first uplink channel and / or the second uplink channel. In this case, not only M resources are the same as N resources, but the difference of the L1-RSRPs corresponding to M resources and N resources is also small, which indicates that the prediction result of the AI / ML model is relatively reliable.

[0338] ● Condition / Event #6: the (predicted) probability corresponding to N resources (based on prediction) is larger than (or equal to) the second threshold. Optionally, the (predicted) probability corresponding to N resources is larger than (or equal to) the second threshold, which means that the (predicted) probability corresponding to the strongest resource in N resources is larger than (or equal to) the second threshold. Optionally, the (predicted) probability corresponding to N resources is larger than (or equal to) the second threshold, which means that the (predicted) probability corresponding to the n-th strongest resource in N resources is larger than (or equal to) the second threshold. Optionally, n may be one of integers ranged from 1 to N. Optionally, n may be any integer ranged from 1 to N. Optionally, the (predicted) probability corresponding to N resources is larger than (or equal to) the second threshold, which means that the (predicted) probability corresponding to each of N resources is larger than (or equal to) the second threshold. Optionally, the second threshold may be predefined, or indicated by the base station (for example, indicated by the base station through at least one of RRC, MAC-CE and DCI), or based on the UE capability. Optionally, the value of the second threshold is greater than or equal to 0. Optionally, the value of the second threshold is less than or equal to 1. Since the value of the probability is generally between 0 and 1, limiting the value range of threshold between 0 and 1 may match the value range of the predicted probability and improve the efficiency of the communication system. Condition / Event #6 may be used to measure the accuracy of prediction. When the probability of the beam predicted by the UE is high, the prediction result of the AI / ML model is relatively reliable. The UE may measure the accuracy of beam prediction based on Condition / Event #6, so as to perform corresponding operations (for example, report to the base station), which facilitates the management of the AI / ML model and improves the performance of communication system. Optionally, Condition / Event #6 may be combined with Condition / Event #4. For example, Condition / Event #4 is not triggered / not satisfied, and Condition / Event #6 is triggered / satisfied, and the UE reports / transmits the first uplink channel and / or the second uplink channel. In this case, not only M resources are the same as N resources, but the corresponding probability of N resources is also high, which indicates that the prediction result of the AI / ML model is relatively reliable.

[0339] The above provides methods related to the monitoring / performance detection of the (UE-side) AI / ML model, so that the base station may manage the UE-side AI / ML model and improve the reliability of the communication system.
