Abstract
Description
Technical Field
[0001] This application relates to the field of wireless communication technologies, and more specifically, to methods and devices for receiving and sending information. Background Art
[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 referred to as "super 4G networks" or "post-LTE systems".
[0003] The 5G communication system is implemented in a higher frequency (millimeter wave, mmWave) band, such as the 60 GHz band, to achieve higher data rates. In order to reduce the propagation loss of radio waves and increase the transmission distance, beamforming, massive multiple-input multiple-output (MIMO), full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and massive antenna technologies are discussed in the 5G communication system.
[0004] In addition, in the 5G communication system, development of system network improvements is underway based on advanced small cells, cloud radio access network (RAN), ultra-dense networks, device-to-device (D2D) communication, wireless backhaul, mobile networks, cooperative communication, coordinated multipoint (CoMP), receiver interference cancellation, etc.
[0005] In the 5G system, hybrid FSK and QAM modulation (FQAM) and sliding window superimposed coding (SWSC) as advanced coding modulation (ACM), as well as filter bank multicarrier (FBMC), non-orthogonal multiple access (NOMA), and sparse code multiple access (SCMA) as advanced access technologies, have been developed.
[0006] Transmission from a base station to a user equipment (UE) is called downlink, and transmission from the UE to the base station is called uplink. Summary of the Invention
[0007] In order to enhance the scheduling efficiency of 5G wireless communication systems, the base station needs to obtain channel state information (CSI) and schedule accordingly based on the CSI feedback from the terminal device. However, how to further enhance the performance related to CSI reporting is an issue that needs to be solved urgently.
[0008] One aspect of the present disclosure provides a method performed by a user equipment (UE) in a wireless communication system. The method includes: receiving a channel state information (CSI) reporting configuration; and reporting CSI based on the CSI reporting configuration, where the CSI reporting configuration includes at least one of a reporting amount parameter, second information related to a function indicating artificial intelligence (AI) enabling, third information related to a model for the function indicating AI enabling, spatial information related to a predicted beam identification ID, temporal information related to a predicted beam identification ID, and first information for indicating enabling or disabling layer 1-reference signal received power (L1-RSRP) reporting, and where the CSI includes at least one of a predicted beam identification ID and / or a predicted L1-RSRP.
[0009] In one example, when the CSI reporting configuration includes spatial information, the CSI is for downlink beam prediction in the spatial domain; and / or when the CSI reporting configuration includes temporal information, the CSI is for downlink beam prediction in the temporal domain; and / or when the CSI reporting configuration includes a reporting amount parameter which is set to 'cri-RSRP' or'ssb-Index-RSRP' and the CSI reporting configuration includes temporal information, the CSI is for downlink beam prediction in the temporal domain.
[0010] 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.
[0011] In one example, when the second information indicates that the AI-enabled function is downlink beam prediction and the second information indicates that the CSI reporting configuration is to report CSI based on model inference, report the predicted beam ID; or when the second information indicates that the AI-enabled function is downlink beam prediction and L1-RSRP prediction and the second information indicates that the CSI reporting configuration is to report CSI based on model inference, report the predicted beam ID and the predicted L1-RSRP corresponding to the predicted beam ID; or when the second information indicates that the CSI reporting configuration is to report CSI based on model inference, and / or the third information indicates that the output of the model includes a beam ID, report the predicted beam ID; or when the second information indicates that the CSI reporting configuration is to report CSI based on model inference, and / or the third information indicates that the output of the model includes a beam ID and L1-RSRP, report the predicted beam ID and the predicted L1-RSRP associated with the predicted beam ID.
[0012] In one example, when the second information indicates downlink beam prediction and / or the CSI reporting configuration is to report CSI based on model inference and the first information indicates that the predicted L1-RSRP is disabled, report the predicted beam ID; or, when the second information indicates downlink beam prediction and / or the CSI reporting configuration is to report CSI based on model inference and the first information is not included, report the predicted beam ID; or, when the second information indicates downlink beam prediction and / or the CSI reporting configuration is to report CSI based on model inference and the first information indicates that the predicted L1-RSRP is enabled, report the predicted beam ID and the predicted L1-RSRP associated with the predicted beam ID.
[0013] 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). The reported CSI includes: when the reporting quantity parameter is set to 'cri-RSRP', the first information indicates that the predicted L1-RSRP is enabled and the CSI reporting configuration includes time information, report the predicted CRI and the predicted L1-RSRP associated with the predicted CRI; or, when the reporting quantity parameter is set to 'cri-RSRP', the first information indicates that the predicted L1-RSRP is disabled and the CSI reporting configuration includes time information, report the predicted CRI; or, when the reporting quantity parameter is set to 'cri-RSRP', the CSI reporting configuration does not include the first information but includes time information, report the predicted CRI; or, when the reporting 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 time information, report the predicted SSBRI and the predicted L1-RSRP associated with the predicted SSBRI; or, when the reporting 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 time information, report the predicted SSBRI; or, when the reporting quantity parameter is set to'ssb-Index-RSRP', the CSI reporting configuration does not include the first information but includes time information, report the predicted SSBRI.
[0014] In one example, the predicted beam ID is associated with one or more time periods determined based on the time information; or, the predicted CRI is associated with one or more time periods determined based on the time information; or, the predicted SSBRI is associated with one or more time periods determined based on the time information; or, the predicted L1-RSRP is associated with one or more time periods determined based on the time information.
[0015] In one example, the number of occupied channel state information processing units (CPUs) associated with the CSI reporting configuration is determined based on at least one of the following: the reporting amount parameter; the first information; the second information; the third information; the spatial information; the temporal information; the resource type of the resource set associated with the CSI reporting configuration; 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; UE capabilities.
[0016] In one example, when the CSI reporting configuration includes the second information and / or the third information, the number of 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 capabilities.
[0017] In one example, when the CSI reporting configuration includes spatial information, the number of occupied CPUs associated with the CSI reporting configuration is determined based on at least one of the beam ID set determined by the spatial information, the resource set associated with the CSI reporting configuration, and the UE capabilities, where the beam ID predicted based on the CSI reporting configuration is from the beam ID set.
[0018] In one example, when the CSI reporting configuration includes temporal information, the number of occupied CPUs associated with the CSI reporting configuration is determined based on at least one of the number of one or more time periods determined by the temporal information, the number of one or more measurement opportunities determined by the temporal information, the number of resources in the resource set associated with the CSI reporting configuration, and the UE capabilities, where the beam ID predicted based on the CSI reporting configuration is associated with one or more time periods determined by the temporal information.
[0019] In one example, the number of occupied CPUs associated with the CSI reporting configuration is determined based on whether the CSI includes predicted L1-RSRP.
[0020] In one example, when the CSI is periodic or semi-persistent, the CPU symbols occupied by the CSI reporting configuration include: from the first symbol of the nearest consecutive Y1 CSI-RS opportunities that are not later than the CSI reference resource, until 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 nearest consecutive Y1 SSB opportunities that are not later than the CSI reference resource, until the last symbol of the PUSCH or PUCCH carrying the CSI reporting.
[0021] In one example, Y1 is determined based on the UE capabilities, or Y1 is indicated by the time information.
[0022] In one example, the time for CSI calculation associated with the CSI reporting configuration is determined based on at least one of the following: 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; the time domain interval between resources in the resource set associated with the CSI reporting configuration; the period 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 type of the resources in the resource set associated with the CSI reporting configuration; UE capabilities.
[0023] 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 domain interval between resources in the resource set associated with the CSI reporting configuration, and the number of resources in the resource set associated with the CSI reporting configuration.
[0024] 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 capabilities.
[0025] In one example, when the resource type of the resources in the resource set associated with the CSI reporting configuration is periodic or semi-persistent, the resource and / or the CSI-RS ports in the resource are counted Y2 times, where Y2 ≥ 0, and where the value of Y2 is predefined or the value of Y2 is indicated by the UE capabilities.
[0026] Another aspect of the present disclosure provides a method performed by a base station in a wireless communication system, the method including: sending a channel state information CSI reporting configuration; receiving CSI reported based on the CSI reporting configuration, where the CSI reporting configuration includes at least one of a reporting quantity parameter, second information related to a function indicating artificial intelligence AI enabling, third information related to a model for the AI enabling function, spatial information, time information, and first information for indicating enabling or disabling layer 1-reference signal received power L1-RSRP reporting, and where the CSI includes at least one of a predicted beam identification ID and / or a predicted L1-RSRP.

[0041] Advantages and features of the present disclosure and ways to implement them will become clear by referring to the embodiments described in detail below in conjunction with the drawings. However, the present disclosure is not limited to the embodiments set forth below, but can be implemented in various different forms. The following embodiments are provided only to fully disclose the present disclosure and to inform those skilled in the art of the scope of the present disclosure, and the present disclosure is limited only by the scope of the appended claims. Throughout the specification, the same or similar reference numerals denote the same or similar elements.
[0042] Figure 1 An exemplary wireless communication network 100 according to various embodiments of the present disclosure is shown. Figure 1 The embodiments of the wireless communication network 100 shown are for illustrative purposes only. Other embodiments of the wireless communication network 100 can be used without departing from the scope of the present disclosure.
[0043] The wireless communication network 100 includes gNodeB (gNB) 101, gNB 102, and 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 proprietary IP network, or other data networks).
[0044] Depending on the type of network, other well-known terms such as "base station (BS)" or "access point (AP)" can be used in place of "gNodeB" or "gNB". For convenience, the terms "gNodeB" and "gNB" are used in the present disclosure to refer to network infrastructure components that provide wireless access to remote terminals. In addition, depending on the type of network, other well-known terms such as "mobile station", "subscriber station", "remote terminal", "wireless terminal", or "user device" can be used in place of "user equipment" or "UE". For convenience, the terms "user equipment" and "UE" are used in the present disclosure to refer to remote wireless devices that wirelessly access the gNB, whether the UE is a mobile device (such as a mobile phone or a smart phone) or a device that is generally considered fixed (such as a desktop computer or a vending machine).
[0045] gNB 102 provides wireless broadband access to network 130 for a first plurality of user equipment (UEs) within coverage area 120 of gNB 102. The first plurality of UEs includes UE 111 that may be located in a small business (SB), UE 112 that may be located in an enterprise (E), UE 113 that may be located in a WiFi hotspot (HS), UE 114 that may be located in a first residence (R), UE 115 that may be located in a second residence (R), and UE 116 that 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 coverage area 125 of gNB 103. The second plurality of UEs includes UE 115 and UE 116. In some embodiments, one or more of gNBs 101-103 are capable of communicating with each other and with UEs 111-116 using 5G, Long Term Evolution (LTE), LTE-A, WiMAX, or other advanced wireless communication technologies.
[0046] The dashed lines illustrate the approximate extent of coverage areas 120 and 125, which are shown as approximately circular merely for purposes of illustration and explanation. It should be clearly understood that the coverage areas associated with a gNB, such as coverage areas 120 and 125, can have other shapes, including irregular shapes, depending on the configuration of the gNB and changes in the radio environment associated with natural and man-made obstacles.
[0047] As 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 design and structure for systems with 2D antenna arrays.
[0048] Although Figure 1 an example of a wireless communication network 100 is shown, various changes can be made to Figure 1 it. For example, wireless communication network 100 can include any number of gNBs and any number of UEs arranged in any suitable manner. And, gNB 101 can communicate directly with any number of UEs and provide wireless broadband access to network 130 for those UEs. Similarly, each of gNBs 102-103 can communicate directly with network 130 and provide direct wireless broadband access to network 130 for UEs. Additionally, gNB 101, gNB 102, and / or gNB 103 can provide access to other or additional external networks, such as an external telephone network or other types of data networks.
[0049] Figure 2A andFigure 2B Transmission path 200 and reception path 250 in a wireless communication network according to various embodiments of the present disclosure are respectively shown. In the following description, transmission path 200 can be described as being implemented in a gNB (such as gNB 102), while reception path 250 can be described as being implemented in a UE (such as UE 116). However, it should be understood that reception path 250 can be implemented in a gNB, and transmission path 200 can be implemented in a UE. In some embodiments, reception path 250 is configured to support codebook design and structure for a system with a 2D antenna array as described in the embodiments of the present disclosure.
[0050] Transmission path 200 includes a channel coding and modulation block 205, a serial-to-parallel (S-to-P) block 210, an N-point inverse fast Fourier transform (IFFT) block 215, a parallel-to-serial (P-to-S) block 220, a cyclic prefix addition block 225, and an upconverter (UC) 230. Reception path 250 includes a downconverter (DC) 255, a cyclic prefix removal block 260, a serial-to-parallel (S-to-P) block 265, an N-point fast Fourier transform (FFT) block 270, a parallel-to-serial (P-to-S) block 275, and a channel decoding and demodulation block 280.
[0051] In transmission path 200, 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 modulation symbols. Serial-to-parallel (S-to-P) block 210 converts (such as demultiplexes) the serial modulation symbols into parallel data to generate N parallel symbol streams, where N is the number of IFFT / FFT points used in gNB 102 and UE 116. N-point IFFT block 215 performs an IFFT operation on the N parallel symbol streams to generate a time-domain output signal. Parallel-to-serial block 220 converts (such as multiplexes) the parallel time-domain output symbols from N-point IFFT block 215 to generate a serial time-domain signal. Cyclic prefix addition block 225 inserts a cyclic prefix into the time-domain signal. Upconverter 230 modulates (such as upconverts) the output of cyclic prefix addition block 225 to an RF frequency for transmission via the wireless channel. The signal can also be filtered at baseband before being converted to the RF frequency.
[0052] The RF signal transmitted from gNB 102 reaches UE 116 after passing through the wireless channel, and operations opposite to those at gNB 102 are performed at UE 116. The downconverter 255 downconverts the received signal to baseband frequency, and the cyclic prefix 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 to a parallel time-domain signal. The N-point FFT block 270 performs the FFT algorithm to generate N parallel frequency-domain signals. The parallel-to-serial block 275 converts the parallel frequency-domain signals to 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.
[0053] Each of gNBs 101-103 may implement a transmit path 200 similar to that for transmitting to UEs 111-116 in the downlink, and may implement a receive path 250 similar to that for receiving from UEs 111-116 in the uplink. Similarly, each of UEs 111-116 may implement a transmit path 200 for transmitting to gNBs 101-103 in the uplink, and may implement a receive path 250 for receiving from gNBs 101-103 in the downlink.
[0054] Figure 2A and Figure 2B each of the components in can be implemented using only hardware, or using a combination of hardware and software / firmware. As a specific example, Figure 2A and Figure 2B at least some of the components in can be implemented in software, while other components can be implemented by configurable hardware or a combination of software and configurable hardware. For example, the FFT block 270 and the IFFT block 215 can be implemented as configurable software algorithms, where the value of the number of points N can be modified according to the implementation.
[0055] Furthermore, although described as using FFT and IFFT, this is merely illustrative and should not be construed as limiting the scope of the present disclosure. Other types of transforms, such as the discrete Fourier transform (DFT) and the inverse discrete Fourier transform (IDFT) functions, can be used. It should be understood that for the DFT and IDFT functions, the value of the variable N can be any integer (such as 1, 2, 3, 4, etc.), while for the FFT and IFFT functions, the value of the variable N can be any integer that is a power of 2 (such as 1, 2, 4, 8, 16, etc.).
[0056] Although Figure 2A and Figure 2B show examples of wireless transmit and receive paths, various changes can be made to Figure 2A and Figure 2B For example,Figure 2A and Figure 2B The various components in can be combined, further subdivided, or omitted, and additional components can be added according to specific needs. Additionally, Figure 2A and Figure 2B are intended to show examples of types of transmit and receive paths that can be used in a wireless network. Any other suitable architecture can be used to support wireless communication in a wireless network.
[0057] Figure 3A An example UE 116 according to various embodiments of the present disclosure is shown. Figure 3A The embodiments of UE 116 shown in are for illustrative purposes only, and Figure 1 UEs 111 - 115 can have the same or similar configurations. However, UEs have a wide variety of configurations, and Figure 3A the scope of the present disclosure is not limited to any particular implementation of the UE.
[0058] UE 116 includes antenna 305, radio frequency (RF) transceiver 310, transmit (TX) processing circuitry 315, microphone 320, and receive (RX) processing circuitry 325. UE 116 also includes speaker 330, processor / controller 340, input / output (I / O) interface 345, (one or more) input devices 350, display 355, and memory 360. Memory 360 includes operating system (OS) 361 and one or more applications 362.
[0059] RF transceiver 310 receives incoming RF signals transmitted by the gNB of wireless network 100 from antenna 305. RF transceiver 310 downconverts the incoming RF signals to generate intermediate frequency (IF) or baseband signals. The IF or baseband signals are sent to RX processing circuitry 325, where RX processing circuitry 325 generates processed baseband signals by filtering, decoding, and / or digitizing the baseband or IF signals. RX processing circuitry 325 sends the processed baseband signals to speaker 330 (such as for voice data) or to processor / controller 340 (such as for web browsing data) for further processing.
[0060] TX processing circuitry 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. TX processing circuitry 315 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate processed baseband or IF signals. RF transceiver 310 receives the outgoing processed baseband or IF signals from TX processing circuitry 315 and upconverts the baseband or IF signals to RF signals transmitted via antenna 305.
[0061] The processor / controller 340 can include one or more processors or other processing devices and execute the OS 361 stored in the memory 360 to control the overall operation of the UE 116. For example, the processor / controller 340 can control the reception of forward channel signals and the transmission of reverse 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.
[0062] The processor / controller 340 can also execute other processes and programs residing in the memory 360, such as operations for channel quality measurement and reporting for a system having a 2D antenna array as described in embodiments of the present disclosure. The processor / controller 340 can move data into or out of the memory 360 as needed for the execution of processes. 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 the I / O interface 345, where the I / O interface 345 provides the UE 116 with the ability to connect to other devices such as laptop computers and handheld computers. The I / O interface 345 is a communication path between these accessories and the processor / controller 340.
[0063] The processor / controller 340 is also coupled to the (multiple) input devices 350 and the display 355. The operator of the UE 116 can use the (multiple) input devices 350 to input data into the UE 116. The display 355 can 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 portion of the memory 360 can include random access memory (RAM), while another portion of the memory 360 can include flash memory or other read-only memory (ROM).
[0064] Although Figure 3A an example of the UE 116 is shown, various changes can be made to Figure 3A it. For example, Figure 3A the various components in Figure 3A can be combined, further subdivided, or omitted, and additional components can be added according to specific needs. As a specific example, the processor / controller 340 can be divided into multiple processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). Additionally, although
[0065] Figure 3BShows an example gNB 102 according to various embodiments of the present disclosure. Figure 3B The embodiment of gNB 102 shown in Figure 1 is for illustration only, and Figure 3B other gNBs can have the same or similar configurations. However, gNBs have a wide variety of configurations, and
[0066] As Figure 3B shown, gNB 102 includes a plurality of antennas 370a - 370n, a plurality of RF transceivers 372a - 372n, transmit (TX) processing circuitry 374, and receive (RX) processing circuitry 376. In some 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.
[0067] The RF transceivers 372a - 372n receive incoming RF signals from the antennas 370a - 370n, such as signals transmitted by a UE or other gNBs. The RF transceivers 372a - 372n down-convert the incoming RF signals to generate IF or baseband signals. The IF or baseband signals are sent to the RX processing circuitry 376, where the RX processing circuitry 376 generates a processed baseband signal by filtering, decoding, and / or digitizing the baseband or IF signal. The RX processing circuitry 376 sends the processed baseband signal to the controller / processor 378 for further processing.
[0068] The TX processing circuitry 374 receives analog or digital data (such as voice data, network data, email, or interactive video game data) from the controller / processor 378. The TX processing circuitry 374 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. The RF transceivers 372a - 372n receive the outgoing processed baseband or IF signal from the TX processing circuitry 374 and up-convert the baseband or IF signal to an RF signal transmitted via the antennas 370a - 370n.
[0069] The controller / processor 378 can include one or more processors or other processing devices that control the overall operation of the gNB 102. For example, the controller / processor 378 can control the reception of forward channel signals and the transmission of reverse channel signals via the RF transceivers 372a - 372n, the RX processing circuitry 376, and the TX processing circuitry 374 according to well-known principles. The controller / processor 378 can also support additional functions, such as more advanced wireless communication functions. For example, the controller / processor 378 can perform BIS processes, such as those performed by the blind interference sensing (BIS) algorithm, and decode received signals from which interference signals have been subtracted. The controller / processor 378 can support any one of a variety of other functions in the gNB 102. In some embodiments, the controller / processor 378 includes at least one microprocessor or microcontroller.
[0070] The controller / processor 378 can also execute programs and other processes resident in the memory 380, such as the 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 RTC. The controller / processor 378 can move data into or out of the memory 380 as needed for the execution of processes.
[0071] The controller / processor 378 is also coupled to the backhaul or network interface 382. The backhaul or network interface 382 allows the gNB 102 to communicate with other devices or systems via a backhaul connection or via a network. The backhaul or network interface 382 can support communication via any suitable wired or wireless connection. For example, when the gNB 102 is implemented as part of a cellular communication system (such as a cellular communication system that supports 5G or new radio access technology or NR, LTE, or LTE-A), the backhaul or network interface 382 can allow the gNB 102 to communicate with other gNBs via a wired or wireless backhaul connection. When the gNB 102 is implemented as an access point, the backhaul or network interface 382 can allow the gNB 102 to communicate with a larger network (such as the Internet) via a wired or wireless local area network or via a wired or wireless connection. The backhaul or network interface 382 includes any suitable structure that supports communication via a wired or wireless connection, such as Ethernet or an RF transceiver.
[0072] Memory 380 is coupled to controller / processor 378. A portion of memory 380 can include RAM, while another portion of memory 380 can include flash memory or other ROM. In some embodiments, a plurality of instructions, such as BIS algorithms, are stored in the memory. The plurality of instructions are configured to cause controller / processor 378 to perform a BIS process and decode a received signal after subtracting at least one interference signal determined by the BIS algorithm.
[0073] As described in more detail below, the transmit and receive paths of gNB 102 (implemented using RF transceivers 372a - 372n, TX processing circuitry 374, and / or RX processing circuitry 376) support communication aggregated with FDD cells and TDD cells.
[0074] Although Figure 3B an example of gNB 102 is shown, various changes can be made to Figure 3B it. For example, gNB 102 can include any number of Figure 3B each component shown in. As a specific example, the access point can include a plurality of backhaul or network interfaces 382, and 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 TX processing circuitry 374 and a single instance of RX processing circuitry 376, gNB 102 can include multiple instances of each (such as one for each RF transceiver).
[0075] To enhance the scheduling efficiency of a 5G wireless communication system, the base station needs to obtain channel state information (CSI) in order to perform scheduling accordingly based on the CSI fed back by the terminal device. However, how to further enhance the performance related to CSI reporting is an issue to be solved.
[0076] Various embodiments of the present application will be described in detail below with reference to the accompanying drawings.

At 402, optionally, the UE determines and / or reports CSI based on the first CSI reporting configuration, where the CSI includes a predicted beam ID and / or a predicted L1-RSRP, and the CSI reporting configuration includes at least one of a reporting quantity parameter, information related to an AI-enabled function (which may also be referred to as function information or second information, etc., and the present application does not limit its naming), information related to a model for the AI-enabled function (which may also be referred to as model information or third information, etc., and the present application does not limit its naming), spatial information, temporal information, and first information for indicating enabling or disabling L1-RSRP reporting. Optionally, the UE reports the CSI corresponding to the first CSI reporting configuration. Optionally, the UE determines and / or reports CSI based on at least one of the reporting quantity parameter included in the first CSI reporting configuration, the function 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 temporal information included in the first CSI reporting configuration, and the first information for enabling or disabling L1-RSRP reporting included in the first CSI reporting configuration. Here, the CSI may be a predicted CSI. Optionally, the CSI includes: a predicted beam identifier (ID) and / or a predicted layer 1 reference signal received power (L1-RSRP). In the present application, the term "beam ID" may be interchangeable with "beam information" or "channel state information reference signal (CSI-RS) resource indicator (CSI-RS Resource Indicator, CRI)" or "SSB resource indicator (SS / PBCH Block Resourceindicator, SSBRI)" or "CRI and / or SSBRI" or "beam resource ID" or "downlink beam resource ID" or "downlink beam information", etc. In the present application, the CSI reported by the UE may be, in one report, or, in one report instance, the CSI reported by the UE's CSI report. 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 the one or more L1-RSRPs are in one-to-one correspondence. Optionally, the L1-RSRP may be a predicted L1-RSRP. Optionally, the L1-RSRP may be a predicted L1-RSRP and a measured L1-RSRP. The following description is made with a predicted L1-RSRP as an example.
[0078] The first CSI reporting configuration may be associated with / correspond to a resource set. Optionally, the resource set may be a measurement resource set. Optionally, the resource set (or, the measurement resource set) may be for channel measurement and / or interference measurement. Optionally, the resource set for channel measurement may be referred to as the second set. Optionally, the first CSI reporting configuration may be associated with / configured / 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 set or a CSI-RS resource set. Optionally, the resource set may be the (one or more) resource sets indicated by the CSI resource configuration parameter CSI-ResourceConfig. Optionally, the resource set may include a CSI-RS resource set (e.g., the resource set indicated by the parameter NZP-CSI-RS-ResourceSet). Optionally, the resource set may include an SSB resource set (e.g., the resource set indicated by the parameter CSI-SSB-ResourceSet). The UE may measure the reference signals in the resource set (or, perform channel measurement).
[0079] The UE receives the first CSI reporting configuration. The UE determines and / or reports CSI based on at least one of the reporting quantity parameter corresponding to / included in the first CSI reporting configuration, the function 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 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 L1-RSRP reporting included in the first CSI reporting configuration, where the CSI includes at least one of a predicted beam ID and / or a predicted L1-RSRP (corresponding to the predicted beam ID).
[0080] For beam prediction on the UE side, the UE needs to perform spatial and / or temporal beam prediction on the downlink beam based on the measurement of the resources in the resource set. To enable the UE to obtain the corresponding information for performing spatial and / or temporal beam prediction, the first CSI reporting configuration configured by the base station may include at least one of a reporting quantity parameter, function information, model information, spatial information, time information, and first information. After obtaining this information, the UE may report the predicted beam ID and / or the predicted L1-RSRP based on this information. Thus, the base station may use the predicted beam ID and / or the predicted L1-RSRP reported by the UE for subsequent scheduling, improving the efficiency of the communication system.
[0081] The reporting quantity parameter (which may also be referred to as the reporting quantity) is further described below.
[0082] The first CSI reporting configuration may include / be configured to indicate a first parameter for the reporting quantity (or, the CSI related quantities to report that need to be reported). For example, the first parameter may be a reporting quantity parameter (e.g., reportQuantity). The first parameter may be set to different values, and each value may correspond to a different reporting quantity. For example, if the reporting quantity parameter included in the first CSI reporting configuration configured for the UE is set to "none", then the UE shall not report any quantity for the first CSI reporting configuration (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 reporting quantity parameter included in the first CSI reporting configuration configured for the UE is not set to "none", then the UE shall report the quantity corresponding to the first CSI reporting configuration (If the UE is configured with a CSI-ReportConfig with the higher layer parameter reportQuantity not set to 'none', then the UE shall report any quantity for the CSI-ReportConfig). The first parameter included in / configured for the first CSI reporting configuration, or, the reporting quantity parameter included in / configured for the first CSI reporting configuration, may be referred to as "the reporting quantity corresponding to the first CSI reporting configuration", or, may be referred to as "the reporting quantity parameter included in the first CSI reporting configuration".
[0083] The functional information and / or model information will be further described below.
[0084] For the artificial intelligence (AI) / machine learning (ML) model on the UE side, the UE and the network device need to align the model / function (e.g., the model / function related to AI / ML) used for CSI reporting (e.g., the CSI reporting corresponding to the first CSI reporting configuration). The following method can be used to clarify the function or model used for CSI reporting. Optionally, the first CSI reporting configuration, or the reference signal resource (or, reference signal resource group) corresponding to the first CSI reporting configuration, is for (or, corresponds to) the model / function related to AI / ML. Optionally, the configuration information of the first CSI reporting configuration, or the reference signal resource (or, reference signal resource group) corresponding to the first CSI reporting configuration, includes functionality information and / or model information. Optionally, the functionality information and / or model information is related to AI / ML. Optionally, the functionality information and / or model information included in the first CSI reporting configuration is based on the AI-enabled model / function supported by the UE reporting. Here, "model" can be interchanged with "AI / ML model". Optionally, the model / function related to AI / ML can be / can be defined as an AI-enabled model / function. Optionally, an AI-enabled model / function refers to a function / model (feature / model where AI / ML may be used) that can use AI / ML. Optionally, the UE can report the AI-enabled functions supported by the UE. For example, the UE can report the AI-enabled functions supported by the UE through UE capability signaling. In this application, "UE capability signaling" can be interchanged with "UE capability". For example, the base station indicates the AI-enabled function used by the UE according to the AI-enabled function supported by the UE reporting. Optionally, the AI-enabled functions include at least one of the following:
[0085] ● Downlink transmission beam prediction;
[0086] ● CSI prediction;
[0087] ● CSI compression.
[0088] In this application, the term "downlink transmission beam prediction" can be interchanged 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".
[0089] It should be noted that whether the UE supports downlink transmission beam prediction is based on the UE capability. For example, the UE can report / indicate whether the UE supports downlink transmission beam prediction through UE capability signaling. For example, the UE can support or not support downlink transmission beam prediction in a predefined manner.
[0090] It should be noted that whether the UE supports the prediction of the L1-RSRP corresponding to the downlink transmission beam prediction is based on the UE's capabilities. For example, the UE can report / indicate whether it supports the prediction of the L1-RSRP corresponding to the downlink transmission beam through UE capability signaling. For example, the UE can support or not support the prediction of the L1-RSRP corresponding to the downlink transmission beam in a predefined manner.
[0091] 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 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 and time domain downlink transmission beam prediction and L1-RSRP prediction.
[0092] Optionally, the first CSI reporting configuration may include model information. Optionally, the model information may be for the function indicated by the function information (or, for the information of the AI / ML enabled function). For example, for the AI / ML enabled function indicated by the function information, the corresponding model information may indicate the ID of the model corresponding to / used by the function. Thus, the UE can know that the first CSI reporting configuration is based on (or, uses) the corresponding function and / or model for model inference through the function information / model information included in the first CSI reporting configuration. Optionally, the association relationship between the function and the corresponding model may be predefined or reported by the UE. For example, the association relationship between the function and the corresponding model may be indicated through UE capability signaling. Thus, the base station and the UE can have a unified understanding of the function / model corresponding to the CSI reporting, so as to better perform function management / model management, improve the performance of AI / ML in the communication system, and further improve the efficiency of the communication system.
[0093] For an AI / ML model (e.g., the UE-side AI / ML model), the UE can use model inference for CSI reporting and / or CSI prediction. The UE and the network device need to have a common understanding of the CSI reporting function for corresponding operations. The following method can clarify the function (or the included function information) corresponding to the first CSI reporting configuration. Optionally, the function information (e.g., the function information included in the first CSI reporting configuration) can be related to AI / ML. Optionally, the first CSI reporting configuration includes function information for indicating that the first CSI reporting configuration is for model inference (or determining / reporting CSI based on model inference). For example, when the first CSI reporting configuration includes function information, the CSI reporting corresponding to the first CSI reporting configuration is determined based on model inference. For example, 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, the UE determines that the CSI reporting (or the reported CSI) corresponding to the first CSI reporting configuration is determined based on model inference. Optionally, the reported CSI can be determined based on the model output.
[0094] The following further describes the spatial information.
[0095] The UE receives a first CSI reporting configuration (e.g., CSI-ReportConfig). The first CSI reporting configuration may include spatial information. The UE may determine a set of beam IDs based on the spatial information. Optionally, the first CSI reporting configuration may include / associate / configure / indicate the set of beam IDs (or, the first set). Optionally, the set of beam IDs may be referred to as the first set. Optionally, the first set may be for prediction. Optionally, the first set may be used for prediction. Optionally, the size of the first set may be K1. Optionally, K1 is indicated by the spatial information. Optionally, the first set includes integers between 0 and K1-1. Optionally, each integer between 0 and K1-1 corresponds to a beam. Optionally, the UE determines the reported predicted CSI based on channel measurements for a second set. Optionally, the value of the predicted CSI may be one of the integers between 0 and K1-1. Optionally, the predicted beam IDs reported (by the UE) corresponding to the first CSI reporting configuration are from the set of beam IDs. For example, the spatial information may include a bitmap for indicating one or more beam IDs (and the one or more beam IDs form a set of beam IDs). For example, the spatial information may explicitly indicate one or more beam IDs (and the one or more beam IDs form a set of beam IDs). Optionally, the spatial information may include / indicate the mapping relationship and / or association relationship between the measurement resource set corresponding to the first CSI reporting configuration and the set of beam IDs. Optionally, the mapping relationship and / or association relationship includes: the quasi-co-location (QCL) relationship between the resources in the measurement resource set and the beams / reference signals / reference signal resources corresponding to the set of beam IDs. Optionally, the mapping relationship and / or association relationship includes: the angular relationship / position relationship between the resources in the measurement resource set and the beams / reference signals / reference signal resources corresponding to the set of beam IDs. Optionally, the set of beam IDs may be a CSI-RS / SSB resource set. Optionally, when the set of beam IDs is a CSI-RS / SSB resource set, the reported beam ID is the predicted SSBRI or the predicted CRI. Optionally, when the set of beam IDs is a CSI-RS / SSB resource set, the UE does not perform measurements on the CSI-RS / SSB resource set. Optionally, when the set of beam IDs is a CSI-RS / SSB resource set, the UE determines whether to perform measurements on the CSI-RS / SSB resource set based on the UE capability or the indication of the base station (e.g., the indication of the first CSI reporting configuration). For example, when the base station configures enable information, the UE performs measurements on the CSI-RS / SSB resource set. For example, when the base station configures disable information (or, does not configure enable information), the UE does not perform measurements on the CSI-RS / SSB resource set.The method for the UE to determine whether the resources in the first set are measured or not is provided above, so that the UE does not measure the first set in some cases to save power consumption, or, in some cases, measures the first set so that the UE can select an AI model according to the measurement results of the first set.
[0096] Optionally, the UE may be instructed / configured to determine information for associating a first set and a second set. Optionally, a first CSI reporting configuration may configure / associate / 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 to as: the association information between the first set and the second set. Optionally, for the first CSI reporting configuration, the UE may be configured with the association information between the first set and the second set. Optionally, the spatial information includes the association information between the first set and the second set. For example, the UE may be configured with the association information between the first set and the second set through the spatial information included in the first CSI reporting configuration. Optionally, the association information between the first set and the second set may include the (one or more) mapping relationships between the elements of the first set and the elements of the second set. For example, for one 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 one mapping relationship, the association information includes parameter k1 and 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 between one element in the first set and one element in the second set may be that one element in the first set and one element in the second set are associated in the spatial domain (e.g., one element in the first set and one element in the second set are quasi-co-located or type D quasi-co-located). Optionally, the association between one element in the first set and one element in the second set may be that one element in the first set and one element in the second set correspond to the same beam (or, correspond to the same spatial domain filter). Optionally, the k1-th element in the first set refers to the k1-th resource in the first set (e.g., the resource with the k1-th largest / smallest resource ID in the first set, or the resource corresponding to / associated with the k1-th item 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 (e.g., 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 item in the configuration information associated with the first set). Optionally, the k1-th element in the first set refers to the integer with a value of k1 - 1 among K1 integers. Optionally, the k1-th element in the first set refers to the predicted value (or, predicted ID, or, 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 (e.g., the resource with the k2-th largest / smallest resource ID in the second set, or the resource corresponding to / associated with the k2-th item in the configuration information associated with the second set).The UE obtaining the association information of the first set and the second set provided by the base station enables the UE to perform inference using the AI / ML model for the association information conforming to the first set and the second set, improving the reliability of the AI / ML model inference, and thus improving the performance of the communication system. The spatial information provides the UE with the necessary information for airspace beam prediction so that the UE can correctly perform airspace prediction, thereby improving the accuracy of airspace beam prediction.
[0097] The time information is further described below. Here, the description of the beam ID can be equivalently applied to the description of "CRI" and / or "SSBRI".
[0098] The UE receives a first CSI reporting configuration (e.g., CSI-ReportConfig). The first CSI reporting configuration may include time information. The UE may determine the time period corresponding to the predicted beam ID corresponding to the first CSI reporting configuration based on this time information. Optionally, when the first CSI reporting configuration includes time information, the predicted beam ID corresponding to the first CSI reporting configuration is associated with one or more time periods (or, F time periods) determined based on this time information. Optionally, the UE may determine the F time periods corresponding to the predicted beam ID corresponding to the first CSI reporting configuration based on this time information. Optionally, F may be one of 1, 2, 3, 4, 5, 6, 7, 8. The method for determining the F time periods through time information may be at least one of the following:
[0099] Method 1: The time information includes the number of time periods (F) and the time offset of the earliest time period among the F time periods. The time unit where the earliest time period among the F time periods is located, or the start position / end position (e.g., start time slot or start symbol or end time slot or end symbol) of the earliest time period among the F time periods, is determined with reference to the time unit (e.g., time slot or symbol) and / or time offset where the CSI report carrying the beam ID is located. The time offset (K) may be an uplink time offset (e.g., uplink time slot offset or uplink symbol offset) or a downlink time offset (e.g., downlink time slot offset or downlink symbol offset). For example, when the time offset is an uplink time slot offset, the start time slot (or the time slot where it is located) of the earliest time period among the F time periods is Or For example, when the time offset is a downlink time slot offset, the start time slot (or the time slot where it is located) of the earliest time period among the F time periods is Or Here, n’ refers to the uplink time slot where the CSI report (carrying the beam ID) is located, and, μ DL and μ ULThey are the downlink subcarrier spacing configuration and the uplink subcarrier spacing configuration respectively. After determining the time position (e.g., start position / end position) of the earliest time period among the F time periods, it is necessary to further determine the time positions (e.g., start position / end position) of the other F-1 time periods. If the time slot where the earliest time period among the F time periods is located or the start time slot / end time is time slot X, then the time slot where the f-th earliest time period among the F time periods is located or the start time slot / end time slot is X+(f-1)*S (e.g., 1≤f≤F). Here, S refers to the interval between two adjacent time periods among the F time periods. Optionally, S can be provided / configured through time information. Optionally, S can be predefined (e.g., S is 1 time slot). Optionally, S is determined based on the period of the measurement resources in the measurement resource set corresponding to the CSI report or the separation between the measurement resources. For example, when the resources in the measurement resource set corresponding to the CSI report are periodic or semi-persistent, this S is determined based on the period of the measurement resources in the measurement resource set corresponding to the CSI report (e.g., a positive integer multiple of the period of the measurement resources). For example, when the resources in the measurement resource set corresponding to the CSI report are aperiodic, this S is determined based on the time interval between the measurement resources in the measurement resource set corresponding to the CSI report (e.g., S is based on the time interval between adjacent measurement resources in the measurement resource set). For example, if the time slot where the earliest time period among the F time periods is located or the start time slot is time slot #1, and the time slot interval is 2, then the time slot where the next time period among the F time periods is located or the start time slot is time slot #3, and the next one is time slot #5, and so on. Optionally, each of the F time periods can have the same length L (L time slots or L symbols). Optionally, L can be predefined. For example, 1 time slot, 2 time slots, 3 time slots, or 4 time slots. For example, 1 symbol, 2 symbols, 3 symbols, or 4 symbols. Optionally, L can be determined based on time information. For example, the value of L is included in the time information.
[0100] Method 2: Method 2 is similar to Method 1, except that the start time unit / end time unit of the earliest time period among the F time periods is determined with reference to the time unit (e.g., time slot or symbol) where the CSI reference resource corresponding to the CSI report carrying the beam ID is located and / or the time offset. For example, when the time offset is an uplink time slot offset, the start time slot (or the time slot where it is located) of the earliest time period among the F time periods is or n CSI_ref is a parameter used to determine the time slot where the CSI reference resource (corresponding to one CSI report) is located. For example, when the time offset is a downlink time slot offset, the start time slot (or the time slot where it is located) of the earliest time period among the F time periods is or Here, n’ refers to the uplink time slot where the CSI report (carrying the beam ID) is located, and μ DL and μ UL are the downlink subcarrier spacing configuration and the uplink subcarrier spacing configuration respectively.
[0101] Method 3: The time information includes F time offsets, where each time offset corresponds to a time period respectively (for example, used to determine the corresponding time period). For example, the f-th time offset (for example, 1 ≤ f ≤ F) is used to determine the start position / end position of the f-th time period. The time unit in which a time period (for example, the f-th time period) is located or the start position / end position of a time period (for example, start time slot or start symbol or end time slot or end symbol) is determined with reference to the time unit (for example, time slot or symbol) where the CSI report carrying the beam ID is located and / or the time offset. The time offset (K) corresponding to the time period can be an uplink time offset (for example, uplink time slot offset or uplink symbol offset) or a downlink time offset (for example, downlink time slot offset or downlink symbol offset). For example, when the time offset (for example, the f-th time offset) is an uplink time slot offset, the start time slot (or the time slot where it is located) of the corresponding time period (for example, the f-th time period) is or For example, when the time offset is a downlink time slot offset, the start time slot (or the time slot where it is located) of the earliest time period among the F time periods is or Here, n’ refers to the uplink time slot where the CSI report (carrying the beam ID) is located, and μ DL and μ UL are the downlink subcarrier spacing configuration and the uplink subcarrier spacing configuration respectively. Optionally, each of the F time periods can have the same length L (L time slots or L symbols). Optionally, L can be predefined. For example, 1 time slot, 2 time slots, 3 time slots, or 4 time slots. For example, 1 symbol, 2 symbols, 3 symbols, or 4 symbols. Optionally, L can be determined based on the time information. For example, the value of L is included in the time information.
[0102] Method 4: The time information includes F time offsets, where each time offset corresponds to a time period respectively (for example, used to determine the corresponding time period). For example, the f-th time offset (for example, 1 ≤ f ≤ F) is used to determine the start position / end position of the f-th time period. The time unit in which a time period (for example, the f-th time period) is located or the start position / end position of a time period (for example, start time slot or start symbol or end time slot or end symbol) is determined with reference to the time unit (for example, time slot or symbol) of the CSI reference resource corresponding to the CSI report carrying the beam ID and / or the time offset. The time offset (K) corresponding to the time period can be an uplink time offset (for example, uplink time slot offset or uplink symbol offset) or a downlink time offset (for example, downlink time slot offset or downlink symbol offset). For example, when the time offset (for example, the f-th time offset) is an uplink time slot offset, the start time slot (or the time slot where it is located) of the corresponding time period (for example, the f-th time period) is Or For example, when the time offset is a downlink time slot offset, the start time slot (or the time slot where it is located) of the earliest time period among the F time periods is Or Here, n’ refers to the uplink time slot where the CSI report (carrying the beam ID) is located, and μ DL And μ UL are the downlink subcarrier spacing configuration and the uplink subcarrier spacing configuration respectively. Optionally, each of the F time periods can have the same length L (L time slots or L symbols). Optionally, L can be predefined. For example, 1 time slot, 2 time slots, 3 time slots, or 4 time slots. For example, 1 symbol, 2 symbols, 3 symbols, or 4 symbols. Optionally, L can be determined based on the time information. For example, the value of L is included in the time information.
[0103] Optionally, when the first CSI report configuration includes time information, the predicted L1-RSRP corresponding to the first CSI report configuration is associated with one or more time periods (or F time periods) determined based on the time information. Optionally, the UE can determine the F time periods corresponding to the predicted L1-RSRP corresponding to the first CSI report configuration based on the time information. Optionally, the predicted L1-RSRP is associated with the predicted beam ID (for example, one-to-one, or one-to-many mapping, or many-to-one mapping).
[0104] The parameter(s) (e.g., the parameter(s) included in the time information) for determining one or more time periods corresponding to / associated with the predicted L1-RSRP and the parameter(s) for determining one or more time periods corresponding to / associated with the predicted L1-RSRP can be the same parameter or different parameters (e.g., the time information respectively includes the parameter(s) for determining one or more time periods corresponding to / associated with the predicted beam ID and the parameter(s) for determining one or more time periods corresponding to / associated with the predicted L1-RSRP). For the method of determining one or more time periods associated with the predicted L1-RSRP based on the parameter, refer to the method of determining one or more time periods associated with the predicted beam ID based on the parameter above.
[0105] A predicted beam ID is associated with a time period. It can be understood that the UE prefers / recommends the predicted beam ID for the corresponding / associated time period, or the UE prefers / recommends the predicted beam ID for base station scheduling for the corresponding / associated time period. A predicted L1-RSRP is associated with a time period. It can be understood that the UE prefers / recommends the L1-RSRP for the corresponding / associated time period, or the UE prefers / recommends the L1-RSRP for base station scheduling for the corresponding / associated time period. In this application, the term "time interval" can be interchanged with terms such as "slot interval", "symbol interval", "time instance", etc.
[0106] Optionally, each of the F time periods can be associated with N F beam IDs. For example, each of the F time periods has N F predicted beam IDs for the corresponding time period. Optionally, the value of N F can be predefined (e.g., one of 1, 2, 3, 4), or the value of N F can be indicated by RRC parameter / MAC-CE signaling / DCI, or the value of N can be indicated by UE capability signaling.
[0107] Optionally, the time information can include measurement window information. The measurement window information can include / indicate the number of measurement windows, the start point / end point of each measurement window, and the width of the measurement window. The UE can determine the measurement window of the measurement resources in the measurement resource set corresponding to the first CSI reporting configuration through the measurement window information. For example, the UE determines the N F beam IDs corresponding to each of the F time periods based on the measurements in X measurement windows, where X and the X measurement windows are determined based on the measurement window information.
[0108] Optionally, the time information may include measurement occasion information. For example, the time information may include the number of measurement occasions, which is used to indicate the number of measurement occasions based on which the CSI report is made. For example, the time information may include the number of measurement occasions (Y1), which is used to indicate that the CSI report is determined based on the (most recent) Y1 measurement occasions. For example, the time information may include the number of measurement occasions (Y1), which is used to indicate that the CSI report is determined based on the most recent consecutive Y1 measurement occasions not later than the CSI reference resource. Here, it is exemplary that the information of the measurement occasion is indicated in the time information, and the measurement occasion information may also be indicated by UE capability signaling.
[0109] The time information provides the UE with the necessary information for time-domain beam prediction, so that the UE can correctly perform time-domain prediction, thereby improving the accuracy of time-domain beam prediction.
[0110] The first information is further described below.
[0111] The UE receives a 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 reporting of predicted L1-RSRP. 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 does not configure 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.
[0112] The first information can facilitate the base station to flexibly select whether to report (predicted) L1-RSRP, improving the flexibility of the communication system.
[0113] The use of the CSI corresponding to the first CSI reporting configuration determined by the time information and / or spatial information included in the first CSI reporting configuration is described below.
[0114] When the first CSI reporting configuration includes spatial information, the CSI corresponding to the first CSI reporting configuration (e.g., predicted beam ID and / or predicted L1-RSRP) is used for spatial-domain downlink beam prediction.
[0115] When the first CSI reporting configuration includes time information, the CSI corresponding to the first CSI reporting configuration (e.g., predicted beam ID and / or predicted L1-RSRP) is used for time-domain downlink beam prediction.
[0116] When the first CSI reporting configuration includes spatial information and the first CSI reporting configuration includes time information, the CSI corresponding to the first CSI reporting configuration (e.g., predicted beam ID and / or predicted L1-RSRP) is used for spatial and time-domain downlink beam prediction.
[0117] When the reported quantity corresponding to the first CSI reporting configuration is set to 'cri-RSRP' or'ssb-Index-RSRP' and the first CSI reporting configuration includes time information, the CSI corresponding to the first CSI reporting configuration (e.g., predicted beam ID and / or predicted L1-RSRP) is used for time-domain downlink beam prediction.
[0118] When the reported quantity corresponding to the first CSI reporting configuration is set to 'cri-RSRP' or'ssb-Index-RSRP', the first CSI reporting configuration does not include spatial information, and the first CSI reporting configuration includes time information, the CSI corresponding to the first CSI reporting configuration (e.g., predicted beam ID and / or predicted L1-RSRP) is used for time-domain downlink beam prediction.
[0119] The above different parameter combinations can enable the UE and the base station to have the same understanding of the purpose of the corresponding CSI, thereby improving the reliability of the communication system.
[0120] The method for the UE to determine and / or report CSI by setting the reported quantity parameter is described below.
[0121] The UE receives the first CSI reporting configuration (e.g., CSI-ReportConfig). Optionally, the UE determines and / or reports CSI based on the reported quantity parameter included (corresponding) in the first CSI reporting configuration, where the CSI includes at least one of: predicted beam ID and / or predicted L1-RSRP (corresponding to the predicted beam ID). For example, under the condition of meeting the first condition (or when the first CSI reporting configuration meets the first condition), the UE determines and / or reports the predicted beam ID and / or predicted L1-RSRP (corresponding to the predicted beam ID).
[0122] An implementation method of the first condition is given below.
[0123] The first condition (or the first condition satisfied by CSI reporting) may include at least one of the following:
[0124] ● The reporting 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'.
[0125] ● The reporting 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'.
[0126] Optionally, when the reporting quantity corresponding to the first CSI reporting configuration is set to the first value, the UE reports the predicted beam ID. Optionally, when the reporting 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, the number of the one or more (different) predicted beam IDs is N (N≥1). Optionally, the number of one or more predicted beam IDs reported by the UE can be predefined (for example, 1 or 2), or indicated by radio resource control (RRC) parameters / media access control control element (MAC-CE) signaling / downlink control information (DCI), or indicated by UE capability signaling.
[0127] Optionally, when the reporting amount corresponding to the first CSI reporting configuration is set to a second value, the UE reports the predicted beam ID and the predicted L1-RSRP. Optionally, when the reporting amount corresponding to the first CSI reporting configuration is set to a second value, the UE reports the predicted N (N≥1) beam IDs and the predicted L1-RSRP corresponding to each beam ID (e.g., N L1-RSRPs). Optionally, the value of N can be predefined (e.g., 1 or 2), or the value of N can be indicated by RRC parameters / MAC-CE signaling / DCI, or the value of N can be indicated by UE capability signaling. The above methods can (explicitly) determine the content included in the reported CSI through the reporting amount parameter included in the first CSI reporting configuration, thereby avoiding using additional information to indicate the content in the reported CSI, reducing the indicated information bits, and improving the efficiency of the communication system.
[0128] The method for the UE to determine and / or report CSI by using the reporting amount parameter and the information for enabling or disabling the L1-RSRP reporting is described below.
[0129] The UE receives the first CSI reporting configuration (e.g., CSI-ReportConfig). Optionally, the UE determines and / or reports CSI based on the reporting amount parameter included in the first CSI reporting configuration and the first information, where 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 can be used to enable or disable the predicted L1-RSRP.
[0130] Optionally, when the reporting amount corresponding to the first CSI reporting configuration is set to a first value (e.g., 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 reporting amount 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 one or more predicted beam IDs reported by the UE can be predefined (e.g., 1 or 2), or indicated by radio resource control (RRC) parameters / media access control control element (MAC-CE) signaling / downlink control information (DCI), or indicated by UE capability signaling.
[0131] Optionally, when the reporting amount 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 is not configured, the UE reports the predicted beam ID. Optionally, when the reporting amount 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 one or more predicted beam IDs reported by the UE can be predefined (for example, 1 or 2), or indicated by radio resource control (RRC) parameters / media access control control element (MAC-CE) signaling / downlink control information (DCI), or indicated by UE capability signaling.
[0132] Optionally, when the reporting amount 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 (predicted) L1-RSRP is enabled, the UE reports the predicted beam ID. Optionally, when the reporting amount corresponding to the first CSI reporting configuration is set to the first value and the first information indicates that (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). Optionally, the number of one or more predicted beam IDs reported by the UE can be predefined (for example, 1 or 2), or indicated by radio resource control (RRC) parameters / media access control control element (MAC-CE) signaling / downlink control information (DCI), or indicated by UE capability signaling.
[0133] The above methods can determine the content included in the reported CSI through the reporting amount parameter corresponding to the first CSI reporting configuration and / or the information for enabling or disabling L1-RSRP reporting, thereby flexibly determining the content in the reported CSI and improving the flexibility of the communication system.
[0134] The method for the UE to determine the CSI reporting content based on the function information and / or model information included in the first CSI reporting configuration is described below.
[0135] The UE receives the first CSI reporting configuration (for example, CSI-ReportConfig). The first CSI reporting configuration includes / corresponds to function information and / or model information.
[0136] Optionally, when the function information included in the first CSI reporting configuration indicates that the function enabled by AI is downlink beam prediction and / or the function information indicates that the first CSI reporting configuration reports CSI based on model inference, the UE determines and / or reports the predicted beam ID.
[0137] Optionally, when the function information included in the first CSI reporting configuration indicates that the function enabled by AI is downlink beam prediction and L1-RSRP prediction and / or the function information indicates that the first CSI reporting configuration reports CSI based on model inference, the UE determines and / or reports the predicted beam ID and the predicted L1-RSRP corresponding to the predicted beam ID.
[0138] Optionally, when the function information included in the first CSI reporting configuration indicates that the first CSI reporting configuration reports CSI based on model inference, and / or the function information model 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.
[0139] Optionally, when the function information included in the first CSI reporting configuration indicates that the first CSI reporting configuration reports CSI based on model inference, and / or the model information indicates that the output of the model includes the beam ID and L1-RSRP, the predicted beam ID and the predicted L1-RSRP corresponding to the predicted beam ID are reported.
[0140] The above methods can (implicitly) determine the content included in the corresponding reported CSI through the function information and / or model information included in the first CSI reporting configuration, thereby avoiding using additional information to indicate the content in the reported CSI, reducing the indicated information bits, and improving the efficiency of the communication system.
[0141] The method for the UE to determine the CSI reporting content based on the function information and / or model information included in the first CSI reporting configuration and the first information for enabling or disabling L1-RSRP reporting is described below.
[0142] The UE receives the first CSI reporting configuration (e.g., CSI-ReportConfig). The first CSI reporting configuration includes / corresponds to function information and / or model information and / or the first information. For example, the first information can be used to enable or disable the predicted L1-RSRP.
[0143] Optionally, when the function 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.
[0144] Optionally, when the function 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.
[0145] Optionally, when the function information included in the first CSI reporting configuration indicates downlink beam prediction and / or model inference and the first information indicates that (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.
[0146] The above methods can determine the content included in the corresponding reported CSI through the function information and / or 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.
[0147] The method for the UE to determine the CSI reporting content based on the reporting quantity parameter included in the first CSI reporting configuration and the first information for enabling or disabling L1-RSRP reporting is described below.
[0148] The UE receives the first CSI reporting configuration (e.g., CSI-ReportConfig). The first CSI reporting configuration includes a reporting quantity parameter (e.g., reportQuantity) and / or the first information and / or time information. For example, the first information is for enabling or disabling L1-RSRP. For example, the first information can be for enabling or disabling predicted L1-RSRP. See the description later for time information.
[0149] The UE reports the predicted beam ID, or reports the predicted beam ID and the predicted L1-RSRP corresponding to the predicted beam ID, based on the reporting quantity parameter included in and / or corresponding to the first CSI reporting configuration and / or the first information and / or time information.
[0150] When the reporting quantity parameter included in the first CSI reporting configuration is set to 'cri-RSRP' and the first information indicates that (predicted) L1-RSRP is enabled (and the first CSI reporting configuration includes time information), the UE determines and / or reports the CSI corresponding to the first CSI reporting configuration, where the CSI includes: the predicted CRI and the predicted L1-RSRP corresponding to the predicted CRI. In this application, the terms "the reporting quantity parameter includes CRI" and "the reporting quantity parameter is set to 'cri-RSRP'" can be used interchangeably. Optionally, when the reporting quantity parameter includes CRI, the beam ID in the reported CSI corresponding to the first CSI reporting configuration is CRI.
[0151] When the reporting 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 time information), or the first information included in the first CSI reporting configuration indicates that (predicted) L1-RSRP is disabled (and the first CSI reporting configuration includes time information), the UE determines and / or reports the CSI corresponding to the first CSI reporting configuration, where the CSI includes: predicted CRI.
[0152] When the reporting quantity parameter included in the first CSI reporting configuration is set to'ssb-Index-RSRP' and the first information indicates that (predicted) L1-RSRP is enabled (and the first CSI reporting configuration includes time information), the UE determines and / or reports the CSI corresponding to the first CSI reporting configuration, where the CSI includes: predicted CRI and (predicted) L1-RSRP corresponding to the predicted beam ID. In this application, the terms "the reporting quantity parameter includes SSBRI" and "the reporting quantity parameter is set to'ssb-Index-RSRP'" can be used interchangeably. Optionally, when the reporting quantity parameter includes SSBRI, the beam ID in the reported CSI corresponding to the first CSI reporting configuration is SSBRI.
[0153] When the reporting quantity parameter includes CRI, the beam ID is CRI (CSI-RS resource indicator).
[0154] When the first CSI reporting configuration includes the reporting quantity parameter set to'ssb-Index-RSRP' and the first CSI reporting configuration does not include the first information, or the first information included in the first CSI reporting configuration indicates that (predicted) L1-RSRP is disabled (and the first CSI reporting configuration includes time information), the UE determines and / or reports the CSI corresponding to the first CSI reporting configuration, where the CSI includes: predicted SSBRI.
[0155] When the first CSI reporting configuration includes the reporting 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 time information), the UE can be considered to support downlink transmission beam prediction.
[0156] When the first CSI reporting configuration includes a reporting quantity parameter set to'ssb-Index-RSRP' or set to 'cri-RSRP' and the first CSI reporting configuration includes first information (and the first CSI reporting configuration includes time information), the UE determines / considers that the first CSI reporting configuration can perform downlink transmission beam prediction.
[0157] When the first CSI reporting configuration includes a reporting quantity parameter set to'ssb-Index-RSRP' or set to 'cri-RSRP' and the first CSI reporting configuration includes first information (and the first CSI reporting configuration includes time information), the UE determines / considers that the first CSI reporting configuration can perform time-domain downlink transmission beam prediction, or the UE determines / considers that the first CSI reporting configuration is for time-domain downlink transmission beam prediction, or the UE determines / considers that the first CSI reporting configuration includes time information. For example, a predicted beam ID (e.g., CRI or SSBRI) and / or the corresponding predicted L1-RSRP are associated with one or more time periods. Here, the one or more time periods can be determined based on the time information. Further descriptions of the time periods and time information are provided below.
[0158] The above methods can determine the content included in the reported CSI and / or the prediction type corresponding to the reported CSI (e.g., time-domain downlink transmission beam prediction) through the reporting quantity and / or the first information included in the first CSI reporting configuration, thereby avoiding using additional information to indicate the content in the reported CSI, reducing the indicated information bits, and improving the efficiency of the communication system.
[0159] In the above method, it is introduced how a UE determines and / or reports CSI (predicted beam ID and / or predicted L1-RSRP) based on at least one of the reporting quantity parameter included in the first CSI reporting configuration, the function information and / or 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 included in the first CSI reporting configuration for enabling or disabling L1-RSRP reporting. For the model inference of the UE-side AI / ML model, since the total computing resources of the UE are limited, it is necessary to specify / determine the computing resources required by the UE during model inference so that the base station can reasonably allocate the computing resources of the UE. In this application, "computing resources" can be equivalently replaced by at least one of "computing power", "computing ability", "occupied computing resources", "consumed computing resources", "CSI computing resources", "resources for AI / ML", "parallel computing resources for AI / ML", "computing resources and / or storage resources for AI / ML", "CSI processing unit (CPU)", or "number of occupied CPUs". The following takes the CPU as an example to describe the method for determining the number of occupied CPUs corresponding to the above first CSI reporting configuration (e.g., O CPU )). The following briefly explains the relevant definitions of O CPU .
[0160] The UE indicates the number of supported parallel CSI calculations N CPU in a component carrier through the single component carrier (CC) parallel CSI parameter (e.g., simultaneousCSI-ReportsPerCC), and indicates the number of supported parallel CSI calculations N CPU across all component carriers through the all-CC parallel CSI parameter (e.g., simultaneousCSI-ReportsAllCC). (The UE indicates the number of supported simultaneous CSI calculations N CPU with parameter simultaneousCSI-ReportsPerCC in a component carrier, and simultaneousCSI-ReportsAllCC across all component carriers.)
[0161] The UE supporting N CPU parallel CSI calculations means that the UE has N CPUA CSI processing unit (CPU) for processing CSI reports. On an OFDM symbol, if L CPUs are occupied, the UE has N CPU – L unoccupied CPUs. (If a UE supports N CPU simultaneous CSI calculations it is said to have N CPU 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 N CPU – L unoccupied CPUs.)
[0162] If N CSI reports start occupying their respective CPUs at the same OFDM symbol and N CPU – L CPUs are not occupied, for each CSI report n = 0, …, N - 1 corresponding to O CPU (n), the UE is not required to update the N – M CSI reports with the lowest priority (required). Here, M refers to the maximum value that satisfies 0 ≤ M ≤ N of. (If N CSI reports start occupying their respective CPUs on the same OFDM symbol on which N CPU – L CPUs are unoccupied, where each CSI report n = 0, …, N - 1 corresponds to O CPU (n), the UE is not required to update the N - M requested CSI reports with the lowest priority, where 0 ≤ M ≤ N is the largest value such that holds.) The processing of a CSI report (e.g., the CSI report corresponding to the first CSI report configuration described above) occupies a number of CPUs for a number of symbols.
[0163] The number of CPUs occupied corresponding to / associated with the above first CSI report configuration (O CPU ) is determined based on at least one of the following:
[0164] ● The reporting volume corresponding to the first CSI report configuration;
[0165] ● The function information and / or model information included in the first CSI report configuration;
[0166] ● The spatial information included in the first CSI report configuration;
[0167] ● The time information included in the first CSI report configuration;
[0168] ● The first information included in the first CSI report configuration;
[0169] ● The resource type of the resource set associated with the first CSI report configuration; The resource type is, for example, one of periodic, semi-persistent, and aperiodic;
[0170] ● UE capability signaling;
[0171] ● The number of resource sets associated with the first CSI report configuration;
[0172] ● The number of resources in the resource set associated with the first CSI report configuration;
[0173] ● The number of predicted beam IDs;
[0174] ● The number of predicted L1-RSRP.
[0175] Optionally, when the first CSI reporting configuration includes function information and / or model information, the number of CPUs occupied associated with the first CSI reporting configuration is determined based on the function information and / or model information and / or UE capability signaling. For example, when the first CSI reporting configuration includes function information and / or model information, the number of CPUs occupied associated with the first CSI reporting configuration is indicated by the function information and / or model information. For example, when the first CSI reporting configuration includes function information and / or model information, the number of CPUs occupied associated with the first CSI reporting configuration is determined based on the number of CPUs occupied corresponding to the function information and / or model information. The mapping relationship between the function information and / or model information and the number of CPUs occupied is predefined or indicated by UE capability signaling.
[0176] Optionally, when the first CSI reporting configuration includes spatial information, the number of CPUs occupied associated with the first CSI reporting configuration is determined based on the spatial information. For example, when the first CSI reporting configuration includes spatial information, the number of CPUs occupied associated with the first CSI reporting configuration is determined based on the set of beam IDs determined by the spatial information and / or the set of measurement resources associated with the first CSI reporting configuration and / or UE capability signaling. Here, the method for determining the set of beam IDs by the spatial information can be referred to the above explanation. For example, when the first CSI reporting configuration includes spatial information, the number of CPUs occupied associated with the first CSI reporting configuration is determined based on the number of beam IDs in the set of beam IDs determined by the spatial information and / or the number of measurement resources in the set of measurement resources associated with the first CSI reporting configuration and / or UE capability signaling. For example, when the first CSI reporting configuration includes spatial information, the number of CPUs occupied associated with the first CSI reporting configuration is determined based on the product / sum of the number of beam IDs in the set of beam IDs determined by the spatial information and / or the number of measurement resources in the set of measurement resources associated with the first CSI reporting configuration and / or the parameters indicated by UE capability signaling. The set of beam IDs can correspond to the output of an AI / ML model, and the set of measurement resources can correspond to the input of an AI / ML model. The number of beam IDs in the set of beam IDs can correspond to the number of outputs of the AI / ML model, and the number of measurement resources in the set of measurement resources can correspond to the number of inputs of the AI / ML model. If the input and / or output of the model changes, it is possible that the architecture of the model itself changes. Therefore, the resources occupied by model inference (i.e., CPU ) may also change. Therefore, the number of CPUs occupied is determined based on the set of beam IDs (the number of beam IDs in it) determined by the spatial information and / or the set of measurement resources (the number of measurement resources in it) associated with the first CSI reporting configuration, which can more accurately reflect the above relationship, avoid the unclear number of CPUs occupied, and improve the reliability of the communication system.
[0177] Optionally, when the first CSI reporting configuration includes time information, the number of occupied CPUs associated with the first CSI reporting configuration is determined based on the time information and / or UE capability signaling. Optionally, when the first CSI reporting configuration includes time information, the number of occupied CPUs associated with the first CSI reporting configuration is determined based on the number of one or more time periods determined by the time information and / or the number of one or more measurement windows determined by the time information and / or UE capability signaling. Optionally, when the first CSI reporting configuration includes time information and the measurement resources in the associated measurement resource set corresponding to the first CSI reporting configuration are periodic or semi-persistent, the number of occupied CPUs associated with the first CSI reporting configuration is determined based on the number of one or more time periods determined by the time information and / or the number of one or more measurement windows determined by the time information and / or UE capability signaling. As the number of measurement windows or the number of time periods increases, the corresponding AI / ML model may become more complex. Therefore, the number of occupied CPUs determined based on the number of one or more time periods determined by the time information and / or the number of one or more measurement windows determined by the time information can more accurately reflect the above relationship, avoid the unclear number of occupied CPUs, and improve the reliability of the communication system.
[0178] Optionally, when the first CSI reporting configuration includes time information, the number of occupied CPUs associated with the first CSI reporting configuration is determined based on the time information and / or UE capability signaling. Optionally, when the first CSI reporting configuration includes time information, the number of occupied CPUs associated with the first CSI reporting configuration is determined based on the number of one or more measurement opportunities determined by the time information and / or UE capability signaling. Optionally, when the first CSI reporting configuration includes time information and the measurement resources in the associated measurement resource set corresponding to the first CSI reporting configuration are periodic or semi-persistent, the number of occupied CPUs associated with the first CSI reporting configuration is determined based on the number of one or more measurement opportunities determined by the time information and / or UE capability signaling. As the number of measurement opportunities for determining CSI reporting increases, the corresponding AI / ML model may become more complex. Therefore, the number of occupied CPUs determined based on the number of one or more time periods determined by the time information and / or the number of one or more measurement windows determined by the time information can more accurately reflect the above relationship, avoid the unclear number of occupied CPUs, and improve the reliability of the communication system.
[0179] Optionally, when the first CSI reporting configuration includes time information, the number of occupied CPUs associated with the first CSI reporting configuration is determined based on the measurement resource set associated with the first CSI reporting configuration and / or UE capability signaling. Optionally, when the first CSI reporting configuration includes time information, the number of occupied CPUs associated with the first CSI reporting configuration is determined based on the number of resources in the resource set associated with the first CSI reporting configuration and / or UE capability signaling. For example, when the first CSI reporting configuration includes time information, the number of occupied CPUs associated with the first CSI reporting configuration is determined based on the product of the number of the measurement resource set associated with the first CSI reporting configuration and the parameters indicated by the UE capability signaling. For example, when the first CSI reporting configuration includes time information and the measurement resources in the measurement resource set associated with the first CSI reporting configuration are aperiodic, the number of occupied CPUs associated with the first CSI reporting configuration may be determined based on the number of the measurement resource set associated with the first CSI reporting configuration and / or UE capability signaling. For example, when the first CSI reporting configuration includes time information and the measurement resources in the measurement resource set associated with the first CSI reporting configuration are aperiodic, the number of occupied CPUs associated with the first CSI reporting configuration may be determined based on the product / sum of the number of the measurement resource set associated with the first CSI reporting configuration and the parameters indicated by the UE capability signaling. Optionally, for an aperiodic measurement resource set, the larger the number of measurement resources in the measurement resource set, the larger the input of the AI / ML model, resulting in a more complex corresponding AI / ML model and thus occupying more CPUs. Therefore, the number of occupied CPUs can be determined based on the number of the measurement resource set associated with the first CSI reporting configuration, which can well reflect this feature, avoid the unclear number of occupied CPUs, and improve the reliability of the communication system.
[0180] Optionally, the number of CPUs occupied associated with the first CSI reporting configuration is determined based on whether the CSI associated with / corresponding to the first CSI reporting configuration includes predicted L1-RSRP. For example, when the CSI associated with / corresponding to the first CSI reporting configuration does not include predicted L1-RSRP, the number of CPUs occupied associated with the first CSI reporting configuration is X1. For example, when the CSI associated with / corresponding to the first CSI reporting configuration includes predicted L1-RSRP, the number of CPUs occupied 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 predicted beam IDs and the case where the CSI associated with / corresponding to the first CSI reporting configuration includes predicted beam IDs and predicted L1-RSRP may correspond to different models, and different models occupy different CPUs. Thus, the fact that the number of CPUs occupied associated with the first CSI reporting configuration is determined based on whether the CSI associated with / corresponding to the first CSI reporting configuration includes predicted L1-RSRP can reflect the above characteristics, thereby avoiding the unclear number of CPUs occupied and improving the reliability of the communication system.
[0181] For the UE-side AI / ML model, the reference signals associated with it can be measured through the first CSI reporting configuration for data collection (e.g., data collection for AI / ML). For example, these reference signals are measured and data collection is performed on the corresponding measurement results. Since data collection only occurs on the UE side, the UE does not need to feedback to the network device. The following method clarifies that CSI reporting does not need to feedback to the base station by specifying configuration parameters. Optionally, a second condition satisfied by the first CSI reporting configuration. Optionally, the second condition may include at least one of the following:
[0182] ● The first CSI reporting configuration is configured not to report CSI (e.g., not to report CSI quantity). For example, the reporting quantity parameter (e.g., reportQuantity) of this CSI reporting configuration is set to "none" (CSI-ReportConfig with higherlayer parameter reportQuantity setto 'none');
[0183] ● The first CSI reporting configuration is configured for data collection. For example, a parameter is configured for the first CSI reporting configuration, and this parameter is used to indicate that this CSI reporting configuration is for data collection. Optionally, when the first CSI reporting configuration is configured with this parameter (or, is configured for data collection, or, is configured for UE-side data collection), the first CSI reporting does not report CSI.
[0184] For the UE-side AI / ML model, CSI reporting (e.g., the first CSI reporting configuration) can be used for data collection for beam management functions. Therefore, the reference signal resources corresponding to CSI reporting are for beam management. The following method specifies the corresponding reference signal resources for beam management by defining configuration parameters. Optionally, a third condition that the first CSI reporting configuration satisfies. Optionally, the third condition may include at least one of the following:
[0185] ● The CSI-RS resources corresponding to the first CSI reporting configuration are not TRS. For example, the CSI-RS resource set parameters (e.g., CSI-RS-ResourceSet or NZP-CSI-RS-ResourceSet) corresponding to the first CSI reporting configuration are not configured with TRS information parameters (with higher layer parameter trs-Info not configured);
[0186] ● The CSI-RS resources corresponding to the first CSI reporting configuration are for beam management. For example, the CSI-RS resource set parameters (e.g., CSI-RS-ResourceSet or NZP-CSI-RS-ResourceSet) corresponding to the first CSI reporting configuration are configured with repetition parameters (with higher layer parameter repetition configured);
[0187] ● The CSI-RS resource group corresponding to the first CSI reporting configuration is configured with repetition parameters, and the repetition parameter is configured to "on". For example, the repetition parameter of the CSI-RS resource set parameters (e.g., CSI-RS-ResourceSet or NZP-CSI-RS-ResourceSet) corresponding to the first CSI reporting is set to "off" (with higher layer parameter repetition set to 'off');
[0188] ● The CSI-RS resource group corresponding to the first CSI reporting configuration is configured with repetition parameters, and the repetition parameter is configured to "on". For example, the repetition parameter of the CSI-RS resource set parameters (e.g., CSI-RS-ResourceSet or NZP-CSI-RS-ResourceSet) corresponding to this CSI reporting is set to "on" (with higher layer parameter repetition set to 'on');
[0189] ● The first CSI reporting configuration is configured with an SSB resource set; for example, the first CSI reporting configuration is configured with an SSB resource set parameter (e.g., CSI-SSB-ResourceSet).
[0190] ● The first CSI report is configured to report L1-RSRP. For example, the reporting quantity parameter (e.g., reportQuantity) of the CSI reporting configuration parameter (e.g., CSI-ReportConfig) of this 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').
[0191] For the UE-side AI / ML model, CSI reporting (e.g., CSI reporting configuration) can be further utilized for data collection for the CSI acquisition function, so the reference signal resources corresponding to the CSI reporting are for CSI acquisition. The following method clarifies that the corresponding reference signal resources are for CSI acquisition by specifying the configuration parameters. Optionally, a fourth condition satisfied by the first CSI reporting configuration. Optionally, the fourth condition may include at least one of the following:
[0192] ● The CSI-RS resource corresponding to the first CSI reporting configuration is not a TRS. For example, the CSI-RS resource set parameter (e.g., CSI-RS-ResourceSet or NZP-CSI-RS-ResourceSet) corresponding to this CSI reporting configuration is not configured with a TRS information parameter (with higher layer parameter trs-Info not configured);
[0193] ● The CSI-RS resource corresponding to the first CSI reporting configuration is for CSI acquisition. For example, the CSI-RS resource set parameter (e.g., CSI-RS-ResourceSet or NZP-CSI-RS-ResourceSet) corresponding to this CSI reporting configuration is not configured with a repetition parameter (with higher layer parameter repetition not configured), and / or the CSI-RS resource set parameter corresponding to this CSI reporting configuration is not configured with a TRS information parameter.
[0194] For the UE-side AI / ML model, CSI reporting (e.g., the first CSI reporting configuration) can be used for data collection. The UE and the network device need to have a common understanding of the purpose of CSI reporting in order to perform corresponding operations. The following method clarifies the purpose of CSI reporting (e.g., applicable to data collection related to beam management). Optionally, a fifth condition satisfied by the first CSI reporting configuration. Optionally, the fifth condition may include at least one of the following:
[0195] ● 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 a CSI-RS resource set, and the second reference signal resource set is an SSB resource set;
[0196] ● The purpose of the first CSI reporting configuration is indicated as data collection. For example, the base station indicates the purpose of the first CSI reporting as data collection through at least one of DCI, MAC-CE, and RRC signaling. Optionally, the data collection can be UE-side data collection.
[0197] Optionally, the first CSI reporting configuration is for data collection. For example, the base station indicates through at least one of DCI, MAC-CE, and RRC signaling that the first CSI reporting is for data collection. Optionally, the data collection can be UE-side data collection.
[0198] Optionally, when the first CSI reporting configuration satisfies the second condition, the third condition, the fourth condition, and the fifth condition, the determination method of O corresponding to the first CSI reporting configuration is at least one of the following methods: CPU The determination method is at least one of the following methods:
[0199] ● Method 1: O corresponding to the first CSI reporting configuration is predefined. For example, O is equal to one of 0, 1, 0.5, 2 / 3, 2, 3, 4, 5, 6, 7, 8. CPU is predefined. For example, O CPU is equal to one of 0, 1, 0.5, 2 / 3, 2, 3, 4, 5, 6, 7, 8.
[0200] ● Method 2: O corresponding to the first CSI reporting configuration is determined based on UE capability signaling. For example, O CPU is indicated by 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, 8. CPU is indicated by 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, 8.
[0201] ● Method 3: O corresponding to the first CSI reporting configuration is determined based on the mapping / association relationship between the resource sets corresponding to / associated with the first CSI reporting configuration, including a first set and a second set. CPU is determined based on the mapping / association relationship between the resource sets corresponding to / associated with the first CSI reporting configuration, including a first set and a second set.
[0202] ■ For example, if the resource set corresponding to / associated with the first CSI reporting configuration includes a first resource set and / or a second resource set, and the second resource set corresponding to / associated with the first CSI reporting configuration is a subset of the first resource set, the O corresponding to the first CSI reporting configuration CPU is a specific value (for example, one of 0, 1, 2, 3, or 0).
[0203] ■ For example, if the resource set corresponding to / associated with the first CSI reporting configuration includes a first resource set and a second resource set, and the second resource set corresponding to / associated with the first CSI reporting configuration is not a subset of the first resource set, the O corresponding to the first CSI reporting configuration CPU is a specific value (for example, one of 0, 1, 2, 3, or 1);
[0204] ■ For example, if the resource set corresponding to / associated with the first CSI reporting configuration includes a first resource set and a second resource set, and the first resource set corresponding to / associated with the first CSI reporting configuration is a CSI-RS resource set, and the second resource set corresponding to / associated with the first CSI reporting configuration is an SSB resource set, the O corresponding to the first CSI reporting configuration CPU is a specific value (for example, one of 0, 1, 2, 3, or 1).
[0205] ● Method Four: The O corresponding to the first CSI reporting CPU is determined based on an indication from the base station. For example, the base station explicitly indicates the O corresponding to the first CSI reporting through at least one of DCI, MAC-CE, and RRC signaling CPU .
[0206] ● Method Five: The O corresponding to the first CSI reporting CPU is determined based on the function information and / or model information included in the first CSI reporting configuration. For example, when the function information included in the first CSI reporting configuration corresponds to spatial domain downlink transmission beam prediction, then O CPU is a specific value X ABC . X ABC can be predefined (for example, one of 0, 1, 2, 3, 4) or determined based on UE capability indication. For example, when the function information included in the first CSI reporting configuration corresponds to spatial domain downlink transmission beam prediction, then O CPU is a specific value. For example, the specific value is one of 0, 1, 2, 3, 4, N ABC *X ABC one of them. X ABCIt can be predefined (e.g., one of 0, 1, 2, 3, 4), or determined based on UE capability indication. N ABC It can be predefined (e.g., one of 0, 1, 2, 3, 4), or determined based on UE capability signaling indication.
[0207] Optionally, when the first CSI reporting configuration satisfies the second condition and / or the third condition, the value of O corresponding to the first CSI reporting configuration CPU is 0 (e.g., O CPU = 0). When the first CSI reporting configuration satisfies the second condition and / or the third condition, it can be considered that the first CSI reporting configuration is for data collection. Since data collection may not require CSI calculation, setting the value of O to 0 can avoid the first CSI reporting configuration from occupying CPU computing resources, save the use of computing resources, and improve the efficiency of the communication system. CPU The above provides a method for the CPU occupancy corresponding to the first CSI reporting configuration. This method enables the base station and the UE to have a unified understanding of the CPU occupancy corresponding to the first CSI reporting configuration (e.g., the first CSI reporting configuration for data collection on the UE side), and avoids the UE from incorrectly discarding CSI reports due to incorrectly determining the CPU occupancy, thereby improving the stability of the communication system.
[0208] The symbol of the CPU occupancy corresponding to the above first CSI reporting configuration is determined based on at least one of the following:
[0209] ● The last symbol of the physical uplink shared channel (PUSCH) / physical uplink control channel (PUCCH) carrying the corresponding CSI report;
[0210] ● No later than Y1 (Y1 ≥ 1) consecutive periodic / semi-persistent reference signal opportunities of the CSI reference resource; the reference signal is, for example, CSI-RS and / or SSB;
[0211] ● The type of the corresponding CSI report.
[0212] Here, the type of CSI report can be periodic CSI report, semi-persistent CSI report, or aperiodic CSI report.
[0213]
[0214] When the higher layer parameter (e.g., report quantity parameter) included in the first CSI report configuration corresponding to a CSI report is not set to "none", the symbols occupied by the CPU are described as follows. If the report corresponding to the first CSI report configuration is a periodic CSI report or a semi-persistent CSI report, then the CSI report occupies the CPU no later than the first symbol of the Y1-th latest consecutive CSI-RS occasions of the CSI reference resource, or no later than the first symbol of the Y1-th latest consecutive SSB occasions of the CSI reference resource, until the last symbol of the PUSCH / PUCCH carrying the CSI 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 report configuration. Optionally, Y1 is predefined, for example, one of 1, 2, 3, 4. Optionally, Y1 is based on UE capabilities. For example, Y1 is indicated by UE capability signaling.
[0215] In the above method, it is introduced how a UE determines and / or reports CSI (predicted beam ID and / or predicted L1-RSRP) based on at least one of the reporting quantity parameter included in the first CSI reporting configuration, the function information and / or 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 information for enabling or disabling L1-RSRP reporting included in the first CSI reporting configuration. When the measurement resource set associated with / corresponding to the first CSI reporting configuration is aperiodic and the CSI reporting corresponding to the first CSI reporting configuration is also aperiodic, the DCI format for triggering CSI reporting, the triggered measurement resources, and the PUSCH carrying the CSI reporting need to meet the CSI calculation delay requirement. The method for determining the CSI calculation time associated with the first CSI reporting configuration is described below. In this application, the term "CSI calculation time" can be interchanged with terms such as "CSI computation delay requirement" or "Z timeline". A brief description of the definition of CSI calculation time is given below.
[0216] The UE may receive a downlink control information (DCI). Optionally, the DCI triggers an aperiodic report. Optionally, the DCI (or the CSI request field included in the DCI) may trigger one or more CSI reports (on the 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) a first CSI report.
[0217] Optionally, the one or more CSI reports include / correspond to a first CSI report. For example, the first CSI report represents the nth (triggered) report among one or more reports.
[0218] Optionally, the UE determines / feeds back / reports the first CSI report (or the UE provides a (valid) CSI report for the first CSI report). Optionally, when at least one of the following conditions is met, the UE determines / feeds back / reports the first CSI report (or the UE provides a (valid) CSI report for the first CSI report):
[0219] ● The time unit (starting) carrying one or more CSI reports is not earlier than the first time unit. For example, the unit of this time unit can be a time slot or a symbol. For example, the time unit carrying one or more CSI reports can be the first uplink symbol carrying one or more CSI reports. Optionally, the uplink symbol includes (or, the effect of the timing advance needs to be considered). The description of the first time unit (e.g., Z ref ) is described below;
[0220] ● The time unit (starting) carrying the first CSI report is not earlier than the second time unit. For example, the unit of this time unit can be a time slot or a symbol. For example, the time unit carrying the first CSI report can be the first uplink symbol carrying the first CSI report. Optionally, the uplink symbol includes (or, the effect of the timing advance needs to be considered). The description of the second time unit is described below.
[0221] Optionally, the first time unit (e.g., Z ref ) is determined based on the time unit where the physical downlink control channel (PDCCH) corresponding to the DCI (e.g., the DCI triggering one or more CSI reports) is located and the CSI calculation delay parameter corresponding to one (or, each) of the one or more CSI reports. Optionally, the first time unit can be an uplink symbol (e.g., the next uplink symbol) after the last symbol (the first specific time) of the PDCCH corresponding to the DCI (e.g., the DCI triggering one or more CSI reports). Optionally, the first specific time is determined based on the CSI calculation delay parameter corresponding to one (or, each) of the one or more CSI reports. For example, Z ref is defined as the next uplink symbol, and the start of the next uplink symbol (including its cyclic prefix (CP)) is at T proc,CSI =(Z)(2048 + 144)·κ2 -μ ·T C +T switch after the end of the physical downlink control channel (PDCCH) triggering (multiple) CSI reports (the next uplink symbol with its CP startingT proc,CSI =(Z)(2048 + 144)·k2 -μ ·T C +T switcafter the end of the last symbol of the PDCCH triggering the CSI report(s)). Here, the description of parameter μ can be found in the description of Table 1 below. T C represents the basic time unit for New Radio (NR). κ represents T S and T C the ratio between T S and T C ). T S represents the basic time unit for Long-Term Evolution (LTE). T switch is a parameter used to indicate the uplink handover time gap. For example, T switch is equal to the switching gap duration or is 0. Z represents / is equal to the maximum value of the CSI calculation delay parameter corresponding to each CSI report in the updated CSI report(s) (in one or more CSI reports). Optionally, the updated CSI report(s) (one or more) in one or more CSI reports are determined according to the CSI processing criteria (e.g., rules related to the CSI processing unit (CPU)). For example, the terminal device can determine which CSI reports need to be updated and which CSI reports are not required to be updated based on the total number of CPUs (CSI processing units) and the number of occupied CPUs. Optionally, the updated reports are represented as report #0, report 1,..., report M - 1, where the number of updated reports is M. Optionally, each report can correspond to a CSI calculation delay parameter. For example, the CSI calculation delay parameter corresponding to report m is Z(m), m = 0, 1,..., M - 1.
[0222]
[0223] Optionally, the second time unit (e.g., Z r ′ ef) 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 resource includes resources for channel measurement and / or resources for interference measurement. Optionally, the measurement resource may be an aperiodic resource. Optionally, the measurement resource corresponding to the first CSI report may be the most recent resource among the measurement resources. For example, in the case where there are multiple measurement resources corresponding to the first CSI report, the measurement resource corresponding to the first CSI report refers to the most recent resource (in the time domain) among 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 most recent resource (in the time domain) among the measurement resources used for the first CSI report. Optionally, the second time unit may be an uplink symbol after the last symbol (of the second specific time) of the most recent resource (in the time domain) among the measurement resources used 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 among one or more CSI reports. For example, taking the first CSI report as an example, Z r ′ ef is defined as the next uplink symbol when the aperiodic CSI-RS for channel measurement is used for the first CSI report, and the start of the next uplink symbol (including its CP) is at the end of the last symbol of the one that is the most recent in time among the aperiodic CSI-RS resource for channel measurement, the aperiodic CSI-IM for interference measurement, and the aperiodic NZP CSI-RS resource for interference measurement, T′ proc,CSI =(Z′)(2048 + 144)·k2 -μ ·T C and then (the next uplink symbol with its CP starting T′ proc,CSI =(Z′)(2048 + 144)·κ2 -μ ·T Cafter the end of the last symbol in time of the latest of: an aperiodic CSI-RS resource for channel measurements, an aperiodic CSI-IM used for interference measurements, and an aperiodic NZP CSI-RS for interference measurement, when an aperiodic CSI-RS is used for channel measurement for the first CSI report). Here, the description of parameter μ can be found in the description of Table 1. T C represents the basic time unit for NR. κ represents T S and T C the ratio between T S and T C ). T S represents the basic time unit for LTE. Z′ represents the maximum value of the CSI calculation delay parameter corresponding to each CSI report in the updated CSI reports (in one or more CSI reports). Optionally, the updated (one or more) CSI reports in one or more CSI reports are determined according to CSI processing criteria (e.g., rules related to the CPU). For example, the terminal device can determine which CSI reports need to be updated and which CSI reports are not required to be updated based on the total number of CPUs (CSI processing units) and the number of occupied CPUs. Optionally, the updated reports are denoted as report #0, report 1,..., report M - 1, where the number of updated reports is M. Optionally, each report can correspond to a CSI calculation delay parameter. For example, the CSI calculation delay parameter corresponding to report m is Z′(m), m = 0, 1,..., M - 1.
[0224] Optionally, the UE can receive a DCI. Optionally, the DCI triggers an aperiodic report. Optionally, the DCI (or the CSI request field included in the DCI) can trigger one or more CSI reports (on the PUSCH).
[0225] Optionally, when the time unit (starting) carrying one or more CSI reports is earlier than the first time unit, the UE ignores the DCI (or, the scheduling DCI). For example, the DCI is the DCI that triggers the one or more CSI reports. Optionally, the time unit carrying one or more CSI reports includes (or, takes into account) the effect of the timing advance. Here, the first time unit refers to the description above.
[0226] Optionally, when the time unit (starting) carrying the first CSI report is earlier than the second time unit, the UE performs at least one of the following operations:
[0227] ● If there is no hybrid automatic repeat request - acknowledgement (HARQ - ACK) or transport block multiplexed on the PUSCH and the number of one or more CSI reports reported is 1, the UE ignores the DCI (or, the scheduling DCI);
[0228] ● Otherwise, the UE is not required to update the first CSI report.
[0229] Optionally, the time unit carrying the first CSI report includes (or, takes into account) the effect of the timing advance. Here, the second time unit refers to the description above.
[0230] For example, Z 1 , Z 2 , Z 3 , Z 1 ′ , Z 2 ′ , Z 3 ′ can be represented by Table 1 below. Here, μ in Table 1 corresponds to μ PDCCH , μ CSI-RS , μ UL 's minimum value min(μ PDCCH , μ CSI- , μ UL ). Here, μ PDCCH corresponds to the sub - carrier spacing of the physical downlink control channel (PDCCH), where the above DCI (e.g., the DCI that triggers the CSI report) is carried / sent through the PDCCH. μ UL corresponds to the sub - carrier spacing of the PUSCH, where the PUSCH is used to carry / send the CSI report.CSI- The minimum / maximum subcarrier spacing in the aperiodic CSI-RS triggered by the corresponding DCI. Optionally, the aperiodic CSI-RS triggered by the DCI refers to the (one or more) resources (e.g., CSI-RS resources) indicated by the (all) sub-configurations triggered by the DCI. Additionally, X μ is determined based on the UE-reported capability parameter (e.g., beamReportTiming). KB l is determined based on the UE-reported capability parameter (e.g., beamSwitchTiming).
[0231] Table 1
[0232]
[0233] Taking the reporting m corresponding to the above-mentioned first CSI reporting configuration as an example, the method for determining the CSI calculation time (e.g., Z(m) and Z′(m)) corresponding to the first CSI reporting configuration is described below.
[0234] In this application, Z(m) can be interchanged with the term "first CSI calculation time" or "first CSI calculation delay parameter" or "first CSI calculation time corresponding to reporting m" or "CSI calculation delay parameter associated with the first time unit corresponding to reporting m" or "CSI calculation delay parameter associated with the first time unit".
[0235] In this application, Z′(m) can be interchanged with the term "second CSI calculation time" or "second CSI calculation delay parameter" or "second CSI calculation time corresponding to reporting m" or "CSI calculation delay parameter associated with the second time unit corresponding to reporting m" or "CSI calculation delay parameter associated with the second time unit".
[0236] When the first CSI reporting configuration corresponding to reporting m is the first CSI reporting configuration, the CSI calculation delay parameter corresponding to reporting m, or, the CSI calculation delay parameter Z(m) associated with the first time unit corresponding to reporting m, or, the first CSI calculation time corresponding to reporting m is determined based on at least one of the following:
[0237] ●Z 3 ;
[0238] ●Z′ 3 ;
[0239] ● The function information and / or model information included in the first CSI reporting configuration;
[0240] ● The number of resource sets associated with the first CSI reporting configuration;
[0241] ● The number of resources in the resource set associated with the first CSI reporting configuration;
[0242] ● The time separation between resources in the resource set associated with the first CSI reporting configuration;
[0243] ● The period corresponding to the resources in the resource set associated with the first CSI reporting configuration;
[0244] ● The 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;
[0245] ● UE capability signaling.
[0246] For beam prediction, since one or more reference signals (one or more transmission opportunities thereof) need to be measured, the CSI calculation time needs to consider reserving the time for the measurement window. Additionally, since the computational complexity required for beam prediction increases, the processing time for CSI reporting may also increase, so additional processing time may be required. Optionally, the first CSI calculation time corresponding to the first CSI reporting configuration (e.g., Z(m)) can be based on Z 3 +W, or based on Z 3 +W+P proc and / or W and / or P 3 determined. Optionally, the first CSI calculation time corresponding to the first CSI reporting configuration (e.g., Z(m)) can be based on Z proc or based on A*Z 3 or determined based on the function information and / or model information included in the first CSI reporting configuration. Optionally, A can be predefined, or A can be indicated by UE capability signaling, or A is indicated by function information and / or model information. Optionally, A can be a positive integer. Optionally, A≥1. Optionally, the value of A can be one of 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 32. Optionally, A = B. Optionally, A and B can be indicated by the same UE capability parameter. Optionally, A and B can be indicated by different UE capability parameters respectively. For the related description of B, see below. When the resource set for channel measurement corresponding to the first CSI reporting configuration is aperiodic, the first CSI calculation time corresponding to the first CSI reporting configuration (e.g., Z(m)) can be based on Z 3 +W, or based on Z 3 +W+P 3 or based on Z proc and / or W and / or P 3 proc Determined. Optionally, W is determined based on at least one of the time domain interval 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 domain interval between the first resource and the last resource in the resource set. The unit of W is symbols. For example, when the first resource in the measurement set is in time slot #x and the last resource is in time slot #y, W = (x – y) * 14. For example, the aperiodic resource sets corresponding to the first CSI reporting configuration respectively correspond to K groups of resources, each group of resources corresponds to resources in P identical time slots, and the K groups are equally spaced in the time domain with a spacing of m. When the unit of m is, for example, time slots, W = (K – 1) * m * 14. Here, K can be indicated by the base station, predefined (e.g., K is 1 or 2), or indicated by UE capability signaling. Here, m can be indicated by the base station, predefined, or indicated by UE capability signaling. Optionally, the first CSI calculation time (e.g., Z(n)) corresponding to the first CSI reporting configuration can be based on Z 3 +W, or based on Z 3 +W+P proc or based on Z 3 and / or W and / or Y1 and / or P proc Determined. 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 period of the resource set or the period (T) of the resources in the resource set and / or Y1. The unit of W is symbols. For example, the resources in the resource set can be SSB or CSI-RS. When the resources in the resource set are CSI-RS, the unit of the period of T is time slots, and W = Y1 * T * 14. When the resources in the resource set are SSB, the unit of the period of T is milliseconds, and W = Y1 * T * 14 * 2 μ . Here, μ represents the subcarrier spacing used for / corresponding to the SSB resources in the receiving resource set. Here, T can be indicated by the base station, predefined, or indicated by UE capability signaling. The definition of Y1 is as described above.
[0247] P proc can represent the CSI reporting processing time. Optionally, P proc can be determined based on Z′ 3 . For example, P proc can be an integer multiple of Z′ 3 . For example, P proc = Z′ 3 , or P proc = 2Z′ 3 . For example, P proc = A * Z′ 3, where A is indicated by UE capability signaling.
[0248] When the first CSI reporting configuration corresponding to m is the first CSI reporting configuration, the CSI calculation delay parameter corresponding to m is reported, or the CSI calculation delay parameter Z′(n) associated with the second time unit corresponding to m is determined based on at least one of the following:
[0249] ● Z′ 3 ;
[0250] ● The function information and / or model information included in the first CSI reporting configuration;
[0251] ● UE capability signaling.
[0252] Since Z′(m) is mainly related to the processing time of CSI reporting, and due to the increased computational complexity required for beam prediction, the processing time of CSI reporting may also increase, so additional processing time may be required.
[0253] Optionally, the second CSI calculation time (e.g., Z′(n)) corresponding to the first CSI reporting configuration may be based on Z′ 3 , or based on B*Z′ 3 , or determined based on the function information and / or model information included in the first CSI reporting configuration. Optionally, B may be predefined (e.g., one of 1, 2, 3, 4), or B may be indicated by UE capability signaling, or B is indicated by function information or model information. Optionally, B may be a positive integer. Optionally, B≥1. Optionally, the value of B may be one of 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 32.
[0254] For periodic or semi-persistent CSI-RS, one transmission opportunity corresponding to a CSI-RS resource may be used for one or more time-domain beam predictions (or, spatial and time-domain beam predictions). Thus, the counting times or the number of times a CSI-RS resource is referenced will increase accordingly. To accurately reflect the counting times of CSI-RS resources and CSI-RS ports in a CSI-RS resource in this case, the determination method / counting method of the active CSI-RS resources and active CSI-RS ports corresponding to / associated with the first CSI reporting configuration is described below, so that the base station and the UE can have a unified understanding of the counting times of CSI-RS resources and CSI-RS ports in a CSI-RS resource, improving the reliability of the communication system.
[0255] When the resources in the resource set associated with the first CSI reporting configuration (for channel measurement) are periodic or semi-persistent CSI-RS resources, the CSI-RS resources and / or the CSI-RS ports in the CSI-RS resources are counted / referred Y2 times (where Y2 ≥ 0, and the value of Y2 is indicated by UE capability signaling).
[0256] Optionally, the UE determines and / or reports CSI based on the first CSI reporting configuration. Optionally, the UE determines and / or reports CSI based on the second set. Optionally, for the UE-side model (or, for UE-side model inference), the UE determines and / or reports CSI based on the second set. Optionally, the UE determines and / or reports CSI based on the second set and / or the first indicator. Optionally, the UE determines and / or reports CSI associated with the first set based on the second set. Optionally, the CSI may include at least one of SSBRI, CRI, L1-RSRP. See the above for the descriptions of the first set and the second set. Optionally, being based on the second set may be: being based on the resources in the second set (e.g., based on the order of the resources in the second set), being based on the channel measurement of the second set (e.g., based on the channel measurement of the resources in the second set). Optionally, the order of the resources in the second set may be at least one of the following:

Optionally, the resource ID may be indicated by NZP-CSI-RS-ResourceId. Optionally, the resource ID may be an SSB ID. Optionally, the resource ID may be an SSB resource ID. Optionally, the resource ID may be indicated by SSB-Index. For example, if the second set includes CSI-RS resource #1, CSI-RS resource #3, CSI-RS resource #2, the ascending order based on the CSI-RS resource ID means: CSI-RS resource #1 → CSI-RS resource #2 → CSI-RS resource #3.
[0258] ● The order of the positions of resources in the configuration information of the second set (e.g., ascending / descending). The order of the positions of resource information in the configuration information of the second set (e.g., ascending / descending). Optionally, when the second set is a CSI-RS resource set, the configuration information of the second set is, for example, NZP-CSI-RS-ResourceSet. Optionally, when the second set is a CSI-RS resource set, the resource information is, for example, (configured) NZP-CSI-RS-Resources. Optionally, when the second set is an SSB resource set, the configuration information of the second set is, for example, CSI-SSB-ResourceSet. Optionally, when the second set is an SSB resource set, the resource information is, for example, (configured) SSB ID (e.g., SSB-Index). For example, in the configuration information of the second set: the first CSI-RS resource information is CSI-RS resource #1; the second CSI-RS resource information is CSI-RS resource #3; the third CSI-RS resource information is CSI-RS resource #2. Then, the ascending order of the positions of the resources (or resource information) in the configuration information of the second set means: CSI-RS resource #1 → CSI-RS resource #3 → CSI-RS resource #2.

Optionally, the order of the precoding vectors associated with resources in the corresponding configuration information. Optionally, the ID order of the precoding vectors associated with resources. Optionally, refer to the above for the method of associating resources with precoding vectors in the second set.

For example, the ascending order based on the (resource-associated) precoding vector ID means: precoding vector #1 → precoding vector #2 → precoding vector #3. For example, the ascending order based on the (resource-associated) precoding vector ID means: CSI-RS resource #1 → CSI-RS resource #2 → CSI-RS resource #3.
[0260] ● The order of the positions of the resources in the second set in the configuration information of the first set (e.g., ascending / descending order). Optionally, the first set includes the resources in the second set (including all the resources in the second set). Optionally, the order of the positions of the resources in the second set in the configuration information of the first set (e.g., ascending / descending order). Optionally, when the first set is a CSI-RS resource set, the configuration information of the first set is, for example, NZP-CSI-RS-ResourceSet. Optionally, when the first set / second set is a CSI-RS resource set, the resource information is, for example, (configured) NZP-CSI-RS-Resources. Optionally, when the first set / second set is an SSB resource set, the configuration information of the first set / second set is, for example, CSI-SSB-ResourceSet. Optionally, when the first set / second set is an SSB resource set, the resource information is, for example, (configured) SSB ID (e.g., SSB-Index). For example, the second set includes CSI-RS resource #2 and CSI-RS resource #3, and in the configuration information of the first set: the first CSI-RS resource information is CSI-RS resource #1; the second CSI-RS resource information is CSI-RS resource #3; the third CSI-RS resource information is CSI-RS resource #2, then the ascending order of the positions of the resources (or resource information) in the second set in the configuration information of the first set means: CSI-RS resource #3 → CSI-RS resource #2.
[0261] The resources in the second set are used for measurement, and the corresponding measurement results are used as the input of the AI / ML model. The UE obtains the corresponding output of the AI / ML model through the input of the AI / ML model to determine and / or report the corresponding predicted CSI. For the input of the AI / ML model, the order of the measurement results for each resource in the second set as the AI / ML input will affect the corresponding output result. Therefore, the above method specifies the order based on which the UE uses the measurement results for the resources in the second set, thus ensuring the reliability of the model output result and further ensuring the reliability of the communication system.
[0262] In some cases, the UE may report UE capabilities (e.g., UE capability signaling), where the information associated with the UE capabilities indicates the maximum number of resources (e.g., total number) supported by the UE. Optionally, the information associated with the UE capabilities indicates the maximum number of resources (e.g., total number) supported in a time slot.

Optionally, the resource refers to a resource for beam prediction. Optionally, the reference signal resource refers to a reference signal resource for CRI / SSBRI / PVI prediction. Optionally, for the UE capabilities (e.g., UE capability signaling), the resources are counted based on the first set and / or the second set. Descriptions of the first set and the second set are as described above. Optionally, for the number of resources (e.g., total number) indicated by the UE capability signaling, the counting of the resource number is based on the first set and / or the second set. For example, the number of times a resource is counted is determined based on whether the resource is in the first set and / or the second set. Optionally, for the first CSI reporting configuration, if a resource is in the second set, the resource is counted once or Z times, where Z is determined based on the UE capabilities. Optionally, for the first CSI reporting configuration, if a resource is in the first set and the UE measures the first set, the resource is counted once. Optionally, for the first CSI reporting configuration, if a resource is in the first set and the UE does not measure the first set, the resource is not counted. Optionally, for the first CSI reporting configuration, if a resource is in the first set, and the resource is in the second set, and the UE measures the first set, the resource is counted twice or Z + 1 times, where Z is determined based on the UE capabilities. Optionally, for the first CSI reporting configuration, if a resource is in the first set, and the resource is in the second set, and the UE does not measure the first set, the resource is counted once or Z times, where Z is determined based on the UE capabilities. Optionally, when the second set is a set of periodic CSI-RS resources / a set of semi-persistent CSI-RS resources / a set of SSB resources, and the first CSI reporting configuration includes time domain information, the number of times the resource is counted is determined based on Z. For example, for the first CSI reporting configuration, if a resource is in the second set, and the second set is a set of periodic CSI-RS resources / a set of semi-persistent CSI-RS resources / a set of SSB resources, and the first CSI reporting configuration includes time domain information, then the resource is counted Z times, where Z is determined based on the UE capabilities.For example, for the first CSI reporting configuration, if a resource is in the second set, and the second set is a periodic CSI-RS resource set / semi-persistent CSI-RS resource set / SSB resource set, and the first CSI reporting configuration includes time domain information, and the resource is in the first set, and the UE measures the first set, then the resource is counted Z + 1 times, where Z is determined based on the UE capability. For example, for the first CSI reporting configuration, if a resource is in the second set, and the second set is a periodic CSI-RS resource set / semi-persistent CSI-RS resource set / SSB resource set, and the first CSI reporting configuration includes time domain information, and the resource is in the first set, and the UE does not measure the first set, then the resource is counted Z times, where Z is determined based on the UE capability. For example, for the first CSI reporting configuration, if a resource is in the second set, and the second set is a periodic CSI-RS resource set / semi-persistent CSI-RS resource set / SSB resource set, and the first CSI reporting configuration includes time domain information, and the resource is not in the first set, then the resource is counted Z times, where Z is determined based on the UE capability. For example, for the first CSI reporting configuration, if a resource is in the second set, and the first CSI reporting configuration does not include time domain information, then the resource is counted 1 time. For example, for the first CSI reporting configuration, if a resource is in the second set, and the first CSI reporting configuration does not include time domain information, and the resource is in the first set, and the UE measures the first set, then the resource is counted 2 times. For example, for the first CSI reporting configuration, if a resource is in the second set, and the first CSI reporting configuration does not include time domain information, and the resource is in the first set, and the UE does not measure the first set, then the resource is counted 1 time. For example, for the first CSI reporting configuration, if a resource is in the second set, and the first CSI reporting configuration does not include time domain information, and the resource is not in the first set, then the resource is counted 1 time. Optionally, the value of Z can be 1, 2, 4, 8. Optionally, the value of Z can be an integer between 1 and 8.

When there is a large gap between the L1-RSRP of the beam predicted by the UE and the L1-RSRP of the beam measured by the UE, it indicates that the prediction result of the AI / ML model is relatively unreliable. The UE can measure the accuracy of the predicted L1-RSRP based on Condition / Event #2 in order to perform corresponding operations (e.g., reporting 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 can be combined with Condition / Event #1. For example, when Condition / Event #1 is not triggered / not satisfied, and Condition / Event #2 is triggered / not satisfied, the UE reports / sends the first uplink channel and / or the second uplink channel. In this case, although the M resources are the same as the N resources, the difference in the L1-RSRP corresponding to the M resources and the N resources is too large, indicating that the prediction result of the AI / ML model is relatively unreliable.
[0320] ● Condition / Event #3: The (predicted) probabilities corresponding to N resources (based on prediction) are less than (or equal to) a second threshold. Optionally, the (predicted) probabilities corresponding to N resources being less than (or equal to) the second threshold means that the (predicted) probability corresponding to the strongest resource among the N resources is less than (or equal to) the second threshold. Optionally, the (predicted) probabilities corresponding to N resources being less than (or equal to) the second threshold means that the (predicted) probability corresponding to the n-th strongest resource among the N resources is less than (or equal to) the second threshold. Optionally, n can be one of the integers between 1 and N. Optionally, n can be any one of the integers between 1 and N.

Optionally, the second threshold can be predefined, or based on the indication of the base station (e.g., indicated by the base station through at least one of RRC, MAC-CE, 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, restricting the value range of the threshold to between 0 and 1 can match the value range of the predicted probability, improving the efficiency of the communication system. Condition / Event #3 can be used to measure the accuracy of the prediction. When the probability of the beam predicted by the UE is low, it indicates that the prediction result of the AI / ML model is relatively unreliable.

Optionally, Condition / Event #3 can be combined with Condition / Event #1. For example, if Condition / Event #1 is not triggered / not satisfied and Condition / Event #3 is triggered / satisfied, the UE reports / sends the first uplink channel and / or the second uplink channel. In this case, although the M resources are the same as the N resources, the probabilities corresponding to the N resources are low, indicating that the prediction result of the AI / ML model is relatively unreliable.

Optionally, when at least one of the following conditions / events is satisfied / triggered, the UE reports / sends the first uplink channel and / or the second uplink channel. Optionally, when at least one of the following conditions / events is satisfied / triggered at a time instance (or, in F time instances, or, in F consecutive time instances, or, in at least one of the F time instances), the UE reports / sends 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 are triggered by at least one of the following events. Optionally, the first uplink channel can be used to notify the base station that the corresponding condition is satisfied / time is triggered. Optionally, the first uplink channel and / or the second uplink channel can include / report information related to prediction. When at least one of the following conditions / events is satisfied / triggered, the result of model inference on the UE side is relatively accurate. Therefore, by transmitting the first uplink channel and / or the second uplink channel, the base station can be notified that the corresponding result of model inference can be used to facilitate subsequent base station management of the model. Additionally, since the result of model inference is relatively accurate, information related to resource prediction can be reported so that the base station can perform beam / resource selection.

Optionally, m can be one of the integers between 1 and M. Optionally, m can be any one of the integers between 1 and M. Optionally, M resources being the same as N resources means that the resources with the same ranking (at least one or all) among M resources and N resources are the same. For example, the strongest resource among M resources is the same as the strongest resource among N resources, and / or the second strongest resource among M resources is the same as the second strongest resource among N resources, and so on. Condition / Event #4 can be used to measure the accuracy rate of beam prediction. When the better beam predicted by the UE is the same as the better beam measured by the UE, it indicates that the prediction result of the AI / ML model is relatively reliable. The UE can measure the accuracy rate of beam prediction based on Condition / Event #4 to perform corresponding operations (such as reporting to the base station), facilitating the management of the AI / ML model and improving the performance of the communication system.
[0323] ● 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) the first threshold. Optionally, the difference between the L1-RSRP corresponding to M resources and the L1-RSRP corresponding to N resources being less than (or equal to) the first threshold means that: the difference between the L1-RSRP corresponding to the m-th strongest resource among the M resources and the (predicted) L1-RSRP corresponding to the m-th strongest resource among the N resources is less than (or equal to) the first threshold. Optionally, m can be one of the integers between 1 and M. Optionally, m can be any one of the integers between 1 and M. Optionally, the difference between the L1-RSRP corresponding to M resources and the L1-RSRP corresponding to N resources being less than (or equal to) the first threshold means that: the difference between the L1-RSRP corresponding to the resources with the same ranking (at least one or all) among the M resources and the N resources is less than (or equal to) the first threshold. For example, the difference between the L1-RSRP corresponding to the strongest resource among the M resources and the L1-RSRP corresponding to the strongest resource among the 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 among the M resources and the L1-RSRP corresponding to the second strongest resource among the N resources is less than (or equal to) the first threshold, and so on.

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 small, it indicates that the prediction result of the AI / ML model is relatively reliable. The UE can measure the accuracy of the predicted L1-RSRP based on Condition / Event #5 to perform corresponding operations (e.g., 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 can be combined with Condition / Event #4. For example, when Condition / Event #4 is triggered / not satisfied, and Condition / Event #5 is triggered / satisfied, the UE reports / sends the first uplink channel and / or the second uplink channel. In this case, not only are the M resources and the N resources the same, but also the difference between the L1-RSRP corresponding to the M resources and the N resources is small, indicating that the prediction result of the AI / ML model is relatively reliable.
[0324] ● Condition / Event #6: The (predicted) probabilities corresponding to N resources (based on prediction) are greater than (or equal to) a second threshold. Optionally, the (predicted) probabilities corresponding to N resources being greater than (or equal to) the second threshold means that: the (predicted) probability corresponding to the strongest resource among the N resources is greater than (or equal to) the second threshold.

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, restricting the value range of the threshold to between 0 and 1 can match the value range of the predicted probability, improving the efficiency of the communication system. Condition / Event #6 can be used to measure the accuracy of the prediction. When the probability of the beam predicted by the UE is high, it indicates that the prediction result of the AI / ML model is relatively reliable.
