Abstract
Description
Technical Field
[0001] This application relates to the field of wireless communication technology, and more specifically, to methods and apparatus for receiving and transmitting information. Background Technology
[0002] To meet the increased demand for wireless data communication services since the deployment of 4G communication systems, efforts have been made to develop improved 5G or near-5G communication systems. Therefore, 5G or near-5G communication systems are also referred to as "super 4G networks" or "post-LTE systems".
[0003] 5G communication systems are implemented in higher frequency (millimeter wave, mmWave) bands, such as the 60GHz band, to achieve higher data rates. To reduce radio wave propagation loss and increase transmission distance, beamforming, massive MIMO, full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and massive MIMO technologies are discussed in 5G communication systems.
[0004] In addition, in 5G communication systems, development is underway to improve system networks based on advanced small cells, cloud radio access networks (RAN), ultra-dense networks, device-to-device (D2D) communication, wireless backhaul, mobile networks, cooperative communication, cooperative multipoint (CoMP), and receiver interference cancellation.
[0005] In 5G systems, hybrid FSK and QAM modulation (FQAM) and sliding window superposition coding (SWSC) have been developed as advanced coding and modulation (ACM), while filter bank multicarrier (FBMC), non-orthogonal multiple access (NOMA) and sparse code multiple access (SCMA) have been developed as advanced access technologies.
[0006] The transmission from the base station to the user equipment (UE) is called the downlink, and the transmission from the UE to the base station is called the uplink. Summary of the Invention
[0007] To enhance the scheduling efficiency of 5G wireless communication systems, base stations need to acquire Channel State Information (CSI) to perform scheduling based on the CSI feedback from terminal devices. However, how to further improve the performance of CSI reporting is an urgent problem to be solved.
[0008] One aspect of this disclosure provides a method performed by a user equipment (UE) in a wireless communication system, the method comprising: receiving a channel state information (CSI) reporting configuration, wherein the CSI reporting configuration is associated with a resource set for channel measurement; reporting X first CSI reports, wherein the CSI in each of the X first CSI reports is for reporting inference and / or prediction and is associated with F time instances, F≥1; and reporting a second CSI report, wherein the CSI in the second CSI report is determined based on a comparison between resources associated with resource indicators included in the CSIs associated with each time instance of each of the X first CSI reports and resources determined based on measurements of the resource set for channel measurement.
[0009] In the example, the CSI reporting configuration indicates the number of resources reported, N1. Each of the X first CSI reports includes N1 resource indicators. The CSI in the second CSI report is determined by comparing the resources associated with the N1 resource indicators in the CSI associated with the f-th time instance of the x-th CSI report among the X first CSI reports with the resources determined by the measurement of the resource set used for channel measurement. Here, x is any integer value between 1 and X, and f is any integer value between 1 and F.

This description includes various specific details to aid understanding but should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of this disclosure. Furthermore, for clarity and brevity, descriptions of well-known functions and structures may be omitted.
[0060] The terms and wording used in the following description and claims are not limited to their dictionary meanings, but are merely used by the inventors to enable a clear and consistent understanding of this disclosure. Therefore, it will be apparent to those skilled in the art that the following description of various embodiments of this disclosure is for illustrative purposes only and not for limiting the purpose of this disclosure as defined in the appended claims and their equivalents.
[0061] It should be understood that the singular forms of “one,” “an,” and “the” include plural references unless the context clearly indicates otherwise. Thus, for example, the reference to “component surface” includes one or more such surfaces.
[0062] The terms “comprising” or “may include” refer to the presence of a corresponding disclosed function, operation, or component that may be used in the various embodiments of this disclosure, rather than limiting the presence of one or more additional functions, operations, or features. Furthermore, the terms “comprising” or “having” may be interpreted as indicating certain characteristics, numbers, steps, operations, constituent elements, components, or combinations thereof, but should not be construed as excluding the possibility of the presence of one or more other characteristics, numbers, steps, operations, constituent elements, components, or combinations thereof.

[0064] Unless otherwise defined, all terms used in this disclosure (including technical or scientific terms) have the same meaning as understood by one of those skilled in the art as described herein. Common terms as defined in dictionaries are to be interpreted as having a meaning consistent with the context in the relevant technical field and should not be interpreted ideally or overly formally unless expressly defined in this disclosure.
[0065] The various embodiments of this disclosure can be applied to various communication systems, such as: Global System for Mobile Communications (GSM) systems, Code Division Multiple Access (CDMA) systems, Wideband Code Division Multiple Access (WCDMA) systems, General Packet Radio Service (GPRS), Long Term Evolution (LTE) systems, Frequency Division Duplex (FDD) systems, Time Division Duplex (TDD) systems, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication systems, 5th Generation (5G) systems, or New Radio (NR), etc. Furthermore, the various embodiments of this disclosure can be applied to future-oriented communication technologies.
[0066] Figure 1 An example wireless network 100 according to various embodiments of the present disclosure is shown. Figure 1 The embodiment of the wireless network 100 shown is for illustrative purposes only. Other embodiments of the wireless network 100 can be used without departing from the scope of this disclosure.
[0067] Wireless 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 network).
[0068] Depending on the network type, other well-known terms such as "base station" or "access point" can be used instead of "gNodeB" or "gNB". For convenience, the terms "gNodeB" and "gNB" are used in this patent document to refer to network infrastructure components that provide wireless access for remote terminals. Furthermore, depending on the network type, other well-known terms such as "mobile station", "user station", "remote terminal", "wireless terminal", or "user device" can be used instead of "user equipment" or "UE". For convenience, the terms "user equipment" and "UE" are used in this patent document to refer to remote wireless devices that wirelessly access the gNB, whether the UE is a mobile device (such as a mobile phone or smartphone) or a fixed device as commonly understood (such as a desktop computer or vending machine).
[0069] gNB 102 provides wireless broadband access to network 130 to multiple first user equipments (UEs) within its coverage area 120. The multiple first UEs include: UE 111, which may be located in a small business (SB); UE 112, which may be located in an enterprise (E); UE 113, which may be located in a WiFi hotspot (HS); UE 114, which may be located in a first residence (R); UE 115, which may be located in a second residence (R); and UE 116, which may be a mobile device (M), such as a cellular phone, wireless laptop computer, wireless PDA, etc. gNB 103 provides wireless broadband access to network 130 to multiple second UEs within its coverage area 125. The multiple second UEs include 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, LTE, LTE-A, WiMAX, or other advanced wireless communication technologies.
[0070] The dashed lines indicate the approximate extent of coverage areas 120 and 125, which are shown as approximately circular for illustrative and explanatory purposes only. It should be clearly understood that coverage areas associated with the gNB, such as coverage areas 120 and 125, can have other shapes, including irregular shapes, depending on the configuration of the gNB and variations in the radio environment associated with natural and man-made obstacles.
[0071] 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 this disclosure. In some embodiments, one or more of gNB 101, gNB 102, and gNB 103 support codebook design and architecture for systems having 2D antenna arrays.
[0072] although Figure 1 An example of a wireless network 100 is shown, but it is possible to... Figure 1 Various modifications can be made. For example, wireless network 100 can include any number of gNBs and any number of UEs in any suitable arrangement. Furthermore, gNB 101 can communicate directly with any number of UEs and provide those UEs with wireless broadband access to network 130. Similarly, each gNB 102-103 can communicate directly with network 130 and provide UEs with direct wireless broadband access to network 130. In addition, gNBs 101, 102, and / or 103 can provide access to other or additional external networks (such as external telephone networks or other types of data networks).
[0073] Figure 2A and Figure 2B Example wireless transmit and receive paths according to this disclosure are shown. In the following description, transmit path 200 can be described as being implemented in a gNB (such as gNB 102), while receive path 250 can be described as being implemented in a UE (such as UE 116). However, it should be understood that receive path 250 can be implemented in a gNB, and transmit path 200 can be implemented in a UE. In some embodiments, receive path 250 is configured to support codebook design and structure for a system having a 2D antenna array as described in embodiments of this disclosure.
[0074] The transmit 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 up-converter (UC) 230. The receive path 250 includes a down-converter (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.
[0075] In transmit 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 modulated symbols. Serial-to-parallel (S-to-P) block 210 converts (e.g., demultiplexes) the serial modulated 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 IFFT operations on the N parallel symbol streams to generate a time-domain output signal. Parallel-to-serial block 220 converts (e.g., 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 (e.g., upconverts) the output of the added cyclic prefix block 225 to an RF frequency for transmission via a wireless channel. The signal can also be filtered at the baseband before being converted to the RF frequency.
[0076] The RF signal transmitted from gNB 102 reaches UE 116 after passing through the wireless channel, and UE 116 performs the opposite operation to that at gNB 102. Downconverter 255 downconverts the received signal to the baseband frequency, and cyclic prefix removal block 260 removes the cyclic prefix to generate a serial time-domain baseband signal. Serial-to-parallel block 265 converts the time-domain baseband signal into a parallel time-domain signal. N-point FFT block 270 performs an FFT algorithm to generate N parallel frequency-domain signals. Parallel-to-serial block 275 converts the parallel frequency-domain signals into a sequence of modulated data symbols. Channel decoding and demodulation block 280 demodulates and decodes the modulated symbols to recover the original input data stream.
[0077] Each of gNBs 101-103 can implement a transmission path 200 similar to that used for transmission to UEs 111-116 in the downlink, and a reception path 250 similar to that used for reception from UEs 111-116 in the uplink. Similarly, each of UEs 111-116 can implement a transmission path 200 for transmission to gNBs 101-103 in the uplink, and a reception path 250 for reception from gNBs 101-103 in the downlink.
[0078] Figure 2A and Figure 2B Each of the components can be implemented using only hardware, or using a combination of hardware and software / firmware. As a specific example, Figure 2A and Figure 2BAt least some of the components can be implemented in software, while others can be implemented in configurable hardware or a combination of software and configurable hardware. For example, FFT block 270 and IFFT block 215 can be implemented as configurable software algorithms, wherein the value of the number of points N can be modified according to the implementation method.
[0079] Furthermore, although the description uses FFT and IFFT, this is merely illustrative and should not be construed as limiting the scope of this disclosure. Other types of transforms, such as the Discrete Fourier Transform (DFT) and Inverse Discrete Fourier Transform (IDFT) functions, can be used. It should be understood that for DFT and IDFT functions, the value of variable N can be any integer (such as 1, 2, 3, 4, etc.), while for FFT and IFFT functions, the value of variable N can be any integer that is a power of 2 (such as 1, 2, 4, 8, 16, etc.).
[0080] although Figure 2A and Figure 2B An example of a wireless transmit and receive path is shown, but it is possible to modify it further. Figure 2A and Figure 2B Make various changes. For example, Figure 2A and Figure 2B The various components can be combined, further subdivided, or omitted, and additional components can be added as needed.

[0083] RF transceiver 302 receives incoming RF signals transmitted by a gNB of wireless network 100 from antenna 301. RF transceiver 302 down-converts the incoming RF signals to generate an intermediate frequency (IF) or baseband signal. The IF or baseband signal is sent to RX processing circuitry 305, which generates a processed baseband signal by filtering, decoding, and / or digitizing the baseband or IF signal. RX processing circuitry 305 sends the processed baseband signal to speaker 306 (e.g., for voice data) or to controller / processor 307 (e.g., for web browsing data) for further processing.
[0084] TX processing circuitry 303 receives analog or digital voice data from microphone 304, or other outgoing baseband data (such as network data, email, or interactive video game data) from controller / processor 307. TX processing circuitry 303 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate processed baseband or IF signals.

Figure 3B The embodiment of gNB 102 shown is for illustrative purposes only, and Figure 1 Other gNBs can have the same or similar configurations. However, gNBs have a wide variety of configurations, and Figure 3B The scope of this disclosure is not limited to any particular implementation of the gNB. It should be noted that gNB 101 and gNB 103 can include the same or similar structures as gNB 102.
[0090] like Figure 3B As shown, gNB 102 includes multiple antennas 370a-370n, multiple RF transceivers 372a-372n, transmit (TX) processing circuitry 374, and receive (RX) processing circuitry 376.

[0091] RF transceivers 372a-372n receive incoming RF signals, such as signals transmitted by the UE or other gNBs, from antennas 370a-370n. RF transceivers 372a-372n down-convert the incoming RF signals to generate IF or baseband signals. The IF or baseband signals are sent to RX processing circuitry 376, which generates processed baseband signals by filtering, decoding, and / or digitizing the baseband or IF signals. RX processing circuitry 376 sends the processed baseband signals to controller / processor 378 for further processing.
[0092] The TX processing circuit 374 receives analog or digital data (such as voice data, network data, email, or interactive video game data) from the controller / processor 378. The TX processing circuit 374 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. RF transceivers 372a-372n receive the outgoing processed baseband or IF signal from the TX processing circuit 374 and up-convert the baseband or IF signal into an RF signal transmitted via antennas 370a-370n.
[0093] The controller / processor 378 may include one or more processors or other processing devices that control the overall operation of the gNB 102. For example, the controller / processor 378 may control the reception of forward channel signals and the transmission of reverse channel signals via RF transceivers 372a-372n, RX processing circuitry 376, and TX processing circuitry 374, according to known principles. The controller / processor 378 may also support additional functions, such as more advanced wireless communication functions. For example, the controller / processor 378 may perform a BIS process, such as by a blind interference sensing (BIS) algorithm, and decode the received signal after subtracting interference. The controller / processor 378 may support any of a wide variety of other functions in the gNB 102.

In some embodiments, the controller / processor 378 supports communication between entities such as web RTCs. The controller / processor 378 is capable of moving data into or out of the memory 380 as needed for the execution of processes.
[0095] The controller / processor 378 is also coupled to a 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 over a network. The backhaul or network interface 382 is capable of supporting communication via any suitable wired or wireless connection(s). For example, when the gNB 102 is implemented as part of a cellular communication system (such as a cellular communication system supporting 5G or new radio access technologies or NR, LTE, or LTE-A), the backhaul or network interface 382 allows 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 allows 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 architecture supporting communication via a wired or wireless connection, such as an Ethernet or RF transceiver.
[0096] Memory 380 is coupled to controller / processor 378. A portion of memory 380 may include RAM, while another portion may include flash memory or other ROM. In some embodiments, multiple instructions, such as a BIS algorithm, are stored in memory. The multiple instructions are configured to cause controller / processor 378 to perform the BIS process and decode the received signal after subtracting at least one interference signal determined by the BIS algorithm.
[0097] As described in more detail below, the transmit and receive paths of the gNB 102 (implemented using RF transceivers 372a-372n, TX processing circuitry 374, and / or RX processing circuitry 376) support aggregated communication with FDD and TDD cells.
[0098] although Figure 3B An example of gNB 102 is shown, but it is possible to compare it with other models. Figure 3B Various modifications can be made. For example, gNB102 can include any number of... Figure 3A Each component shown. As a specific example, an access point can include multiple backhaul or network interfaces 382, and a controller / processor 378 can support routing functions to route data between different network addresses. As another specific example, although shown as a single instance including TX processing circuitry 374 and a single instance including RX processing circuitry 376, the gNB 102 can include multiple instances of each (such as one for each RF transceiver).

[0196] The method described above for generating CSI for performance monitoring allows the UE to compare the results of one or more CSI predictions with the measurement results of the resource set used for monitoring, and reflects the comparison results in the CSI reporting, enabling the UE to report the CSI for performance monitoring. The CSI for performance monitoring facilitates the base station's acquisition of performance metrics from the UE-side model, enabling appropriate model management and improving the reliability of the UE-side AI model.
[0197] Optionally, the CSI associated with the second CSI report configuration (or the CSIs included in the second CSI report) can be determined by comparing the resources associated with the resource indicators included in each of the X first CSI reports with one or more resources (e.g., resources in the third resource set) determined based on measurements of the third resource set. Optionally, the measurement of the third resource set can be a measurement of the resources in the third resource set. Optionally, the measurement of the third resource set can be a measurement of all resources in the third resource set.
[0198] Optionally, the comparison described above can be: a comparison of the resource associated with at least one resource indicator in the xth (1≤x≤X)th (N1)th (1≤x≤X)th)th (N1)th)th)th)th)th)th)th)th)th)th)th)) with one or more)"))))""""""))))""""""!"") is a comparison of the resource associated with at least one)))"'s comparison of the resource associated with at least one ...'s comparison of the resource associated with at least one))"'''''''''''"'th)'''''
[0199] Optionally, the above comparison can be: (determining) whether the resource associated with the N1 resource indicators in the xth CSI report out of X first CSI reports is among the N2 resources with the highest (measured) L1-RSRP in the third resource set determined based on measurements of the third resource set. For example, each resource indicator in the N1 resource indicators is associated with one resource. The UE compares whether the N1 resources associated with the N1 resource indicators in the xth CSI report out of X first CSI reports are among the N2 resources with the highest (measured) L1-RSRP in the third resource set. This comparison method can be referred to as method #1A. Here, N1 resources in N2 resources can be considered as: all N1 resources are in N2 resources, or, every resource in N1 resources is in N2 resources. Here, N1 resources in N2 resources can be considered as: N1 resources in N2 resources are the same as the N1 resources. Optionally, N1 ≤ N2. See below for a description of N2. For example, if the predicted resources are CSI-RS#1 and CSI-RS#2, and the three resources with the highest measured L1-RSRP in the third resource set are CSI-RS#1, CSI-RS#2, and CSI-RS#3, then the predicted resource is among the three resources with the highest measured L1-RSRP in the third resource set. Conversely, if the predicted resources are CSI-RS#1 and CSI-RS#2, and the three resources with the highest measured L1-RSRP in the third resource set are CSI-RS#2, CSI-RS#3, and CSI-RS#4, then the predicted resource is not among the three resources with the highest measured L1-RSRP in the third resource set. This method allows the UE to compare whether the optimal beam in the set for monitoring is within the UE's predicted beam. This helps the base station determine whether the beam prediction matches the actual measured beam, allowing the base station to make adjustments when the prediction deviates from the monitoring results, thus improving the reliability of the communication system.
[0200] Optionally, the above comparison can be: (determining) whether the resource with the highest (measured) L1-RSRP in the third resource set, determined based on measurements of the third resource set, is one of the resources associated with the N1 resource indicators in the xth CSI report out of X first CSI reports. For example, each of the N1 resource indicators is associated with one resource. The UE compares whether the resource with the highest (measured) L1-RSRP in the third resource set is one of the N1 resources associated with the N1 resource indicators in the xth CSI report out of X first CSI reports. This comparison method can be referred to as Method #1. Optionally, the resource associated with the N1 resource indicators can be: the resource associated with one of the N1 resource indicators. For example, one of the N1 resource indicators is associated with one resource. The UE compares whether the resource with the highest (measured) L1-RSRP in the third resource set is associated with the resource associated with one of the N1 resource indicators in the xth CSI report out of X first CSI reports. This comparison method can be referred to as Method #2. This method allows the UE to compare whether the optimal beam in the set for monitoring is in the beam predicted by the UE. This helps the base station determine whether the beam prediction matches the actual measured beam. The base station can then make corresponding adjustments if the prediction deviates from the monitoring results, thereby improving the reliability of the communication system.
[0201] Optionally, the above comparison can be: (determining) whether the resource associated with one of the N1 resource indicators in the xth CSI report among the X first CSI reports is one of the N2 (N2≥1) resources in the third resource set determined based on measurements of the third resource set. Optionally, the N2 resource indicators can indicate / correspond to the best N2 resources in the third resource set. Optionally, the N2 resource indicators can indicate the strongest N1 resources in the third resource set. Optionally, the N2 resource indicators can indicate the N2 resources with the highest (measured) L1-RSRP in the third resource set. Optionally, N2 can be indicated by the base station. For example, N2 is indicated by at least one of RRC, MAC-CE, and DCI. For example, N2 can be indicated by the second CSI report configuration. N2 can be predefined. This comparison method can be referred to as Method #3. This method allows the UE to compare whether the UE's predicted beam is in the optimal set of beams used for monitoring. This helps the base station determine whether the beam prediction matches the actual measured beam. In this way, the base station can make corresponding adjustments when the prediction deviates from the monitoring results, thereby improving the reliability of the communication system.
[0202] Optionally, the above comparison can be: (determining) whether the difference between the (measured) L1-RSRP of the resource associated with one of the resource indicators in the xth CSI report out of the X first CSI reports and the highest (measured) L1-RSRP determined based on measurements of a third resource set is less than a threshold (or, less than / equal to the threshold, or, greater than the threshold, or, greater than / equal to the threshold). Optionally, the threshold can be predefined, or indicated by the base station, or determined based on UE capabilities. Here, the threshold can be T dB. Optionally, T ≥ 0. Optionally, T can be predefined. Optionally, the value of T can be one of 0, 1, 2, 3, 4, 5, 6, 7, 8. Optionally, the value of T can be indicated by the base station, for example, by the configuration of the second CSI report. The value of T can be indicated by at least one of RRC, MAC-CE, DCI. Optionally, the value of T can be determined based on UE capabilities. For example, the value of T is determined based on the indication of the reported UE capability signaling. This comparison method can be called Method #4. This method allows the UE to compare the measured L1-RSRP of the UE's predicted optimal beam with the measured L1-RSRP of the optimal beam in the monitoring set to see if they are within a certain range. This helps the base station determine whether the beam prediction matches the actual measured beam of the monitored beam, so that the base station can make corresponding adjustments when the prediction results deviate from the monitoring results, thereby improving the reliability of the communication system.
[0203] Optionally, the UE may make a comparison using one of the following methods: method #1A, method #1, method #2, method #3, or method #4, based on the base station's indication or a predefined method.

Optionally, when none of the N1 resource indicators have a corresponding L1-RSRP, one of the N1 resource indicators can be the first (or last) resource indicator among the N1 resource indicators. Optionally, the first (or last) resource indicator can be determined based on the order of the CSI information bits associated with / corresponding to the N1 resource indicators.
[0209] In this document, "resource corresponding to L1-RSRP" can mean that the resource has a corresponding L1-RSRP. "Resource not corresponding to L1-RSRP" can mean that the resource does not have a corresponding L1-RSRP. In this document, "resource corresponding to L1-RSRP" can be understood as: the first CSI report includes both CRI / SSBRI and the corresponding L1-RSRP, or the first CSI report is configured to report both CRI / SSBRI and L1-RSRP. In this document, "resource not corresponding to L1-RSRP" can be understood as: the first CSI report includes only CRI / SSBRI, or the first CSI report is configured to report only CRI / SSBRI.
[0210] The following describes the method for determining CSI (e.g., BAI).
[0211] Optionally, the value of BAI is indicated by the BAI field. Optionally, the value k of BAI refers to: k CSI reports out of X first CSI reports have a comparison result of true. Optionally, the value k of BAI refers to: the number of CSI reports out of X first CSI reports with a comparison result of true. Optionally, the value k of BAI refers to: the number of comparisons with true results associated with X first CSI reports. Optionally, the value k of BAI refers to: the number of CSIs associated with X first CSI reports with a comparison result of true. Optionally, the value k of BAI refers to: the number of comparisons with true results associated with X first CSI reports. Here, CSI report can refer to the CSIs included in the CSI report (or, the inference results included in the CSI report). In this document, the term "CSI report" can be used interchangeably with the terms "CSIs included in the CSI report" or "inference results included in the CSI report". For example, the number of CSI reports can be considered as the number of inference results included in the CSI reports. Alternatively, k ≥ 0. Alternatively, k ≤ X.
[0212] The following describes the method for determining the comparison result. Optionally, if A and B are the same, the comparison result of A and B can be considered true. If A and B are different, the comparison result of A and B can be considered false. For example, when at least one resource indicator in the xth CSI report out of X first CSI reports is associated with a resource that is the same as / mapped to a resource determined based on a measurement of a third resource set, the comparison result can be considered true. For example, when at least one resource indicator in the xth CSI report out of X first CSI reports is associated with a resource that is different from (or not mapped to) a resource determined based on a measurement of a third resource set, the comparison result can be considered false. Optionally, if A and B are less than (or less than / equal to) a specific threshold, the comparison result for whether A and B are less than (or less than / equal to) the specific threshold can be considered true; otherwise, the comparison result can be considered false.
[0213] In this paper, a comparison result being true can also be described as: the metric (or performance metric) related to the comparison being satisfied. For example, if comparing whether A and B are the same, then "A and B are the same" can be understood as a metric related to the comparison. The comparison result is true when the metric related to the comparison is satisfied (e.g., "A and B are the same" is satisfied).
[0214] In this paper, a false comparison result can also be described as: the metric (or performance metric) related to the comparison is not satisfied. For example, if comparing whether A and B are the same, "A and B are the same" can be understood as a metric related to the comparison. When the metric related to the comparison is not satisfied (e.g., "A and B are not the same"), the comparison result is false.
[0215] In this document, X first CSI reports can correspond to X CSI reporting opportunities. Optionally, the X first CSI reports can be: the first CSI report in X CSI reporting opportunities. If a CSI report is not sent in a CSI reporting opportunity, the UE can assume that the comparison result corresponding to that CSI report is predefined. For example, the comparison result is true. For example, the comparison result is false. For example, for the calculation / determination of BAI, if a CSI report is not sent in a CSI reporting opportunity, the UE can assume that the comparison result corresponding to that CSI report is true. For example, for the calculation / determination of BAI, if a CSI report is not sent in a CSI reporting opportunity, the UE can assume that the comparison result corresponding to that CSI report is false. This method allows the UE and the base station to have a common understanding of the comparison results corresponding to the possible CSI report when the UE does not send a CSI report at the corresponding CSI reporting opportunity. This avoids the base station and the UE interpreting the corresponding beam accuracy based on different comparison results corresponding to the CSI report, thereby improving the reliability of the communication system.
[0216] Optionally, the accuracy rate corresponding to BAI is Optionally, the accuracy corresponding to BAI can be the accuracy of inference / prediction. Optionally, the accuracy can be the accuracy of the first CSI report. Optionally, the accuracy can be the accuracy of the inference / prediction results associated with the first CSI report.

Optionally, the value k of BAI can refer to the number of CSI reports with a comparison result of true among X first CSI reports.
[0217] Optionally, the value k of BAI can refer to: the number of CSI reports with a comparison result of false out of X first CSI reports. Alternatively, the value k of BAI can refer to the number of CSI reports with a comparison result of false out of X first CSI reports. In this case, the accuracy corresponding to BAI is... or,
[0218] Optionally, the size of the BAI field (or the field corresponding to BAI) is Or, log2X. Here, This refers to the rounding up operation. Optionally, the size of the BAI field (or the field corresponding to BAI) is determined based on X+1. For example, the size of the BAI field (or the field corresponding to BAI) is equal to... Or, log2(X+1), or, or, Here, A can be an integer greater than or equal to 1. For example, A can be one of 1, 2, 3, 4, 5, 6, 7, or 8. Optionally, A can be predefined or A can be indicated / configured by the base station. Since the value range of BAI can be from 0 to X, that is, BAI can indicate X+1 values, determining the size of the BAI field based on X+1 can avoid some values from 0 to X not being indicated, thus improving the reliability of UE CSI reporting and consequently improving the reliability of the communication system.
[0219] Optionally, X refers to the total number of CSI reports being compared. Optionally, X refers to the total number of CSI reports being compared in a reporting instance. Optionally, X refers to the total number of CSI reports used to determine the BAI in a reporting instance. Optionally, X can be the number of CSIs in the CSI reports. Optionally, X can be the number of CSIs in X first CSI reports. For example, each CSI report in X CSI reports includes one CSI. For example, X CSI reports include X CSIs. In this document, the CSIs in the first CSI reports can be referred to as: prediction results, or inference results. Optionally, X (or the value of X) can be indicated by the base station, or predefined, or determined based on UE capabilities. For example, the value of X can be one of 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 32. For example, X can be indicated by at least one of RRC, MAC-CE, and DCI. For example, X can be indicated by the second CSI reporting configuration.
[0220] The above method enables the UE to obtain the value of X (i.e., the total number of CSI reports being compared), so that the UE can obtain the corresponding beam accuracy by the number (k) of CSI reports with true / false results, thereby saving the overhead of CSI reporting.
[0221] The following describes another method for determining CSI (e.g., BAI). Optionally, the accuracy corresponding to BAI is... Optionally, the accuracy corresponding to BAI can be the accuracy of inference / prediction. Optionally, the accuracy can be the accuracy reported by the first CSI.

Optionally, the accuracy can be the accuracy of the inference / prediction (reported) associated with the configuration reported by the first CSI. Optionally, the accuracy can be the accuracy of the inference / prediction results (reported) associated with the configuration reported by the first CSI. Optionally, the value of BAI can be m. Optionally, the value m of BAI can refer to: there are m measurements associated with the third resource set whose comparison results are true. Optionally, the value m of BAI can refer to the number of measurements among one or more measurements associated with the third resource set whose comparison results are true. For example, one or more measurements associated with the third resource set can be M measurements associated with the third resource set. Optionally, M ≥ 1. Optionally, m measurements associated with the third resource set are derived from M measurements associated with the third resource set. Optionally, 0 ≤ m ≤ M.
[0222] Optionally, the value m of BAI can refer to the number of comparison results that are false for m measurements associated with the third resource set. Alternatively, the value m of BAI can refer to the number of measurements among one or more measurements associated with the third resource set whose corresponding comparison results are false. In this case, the accuracy corresponding to BAI is... or,
[0223] Optionally, the size of the BAI field (or the field corresponding to BAI) is Or, log2M. Here, This refers to the floor operation. Optionally, the size of the BAI field (or the field corresponding to BAI) is determined based on M+1. For example, the size of the BAI field (or the field corresponding to BAI) is equal to... Or, log2(M+1), or, or, Here, B can be an integer greater than or equal to 1. For example, B can be one of 1, 2, 3, 4, 5, 6, 7, or 8. Optionally, B can be predefined or indicated / configured by the base station. Since the value range of BAI can be from 0 to M, that is, BAI can indicate M+1 values, determining the size of the BAI field based on M+1 can avoid some values from 0 to M not being indicated, thus improving the reliability of UE CSI reporting and consequently improving the reliability of the communication system.
[0224] Optionally, M refers to the total number of one or more measurements associated with the third resource set being compared. Optionally, M refers to the total number of measurements being compared in a reporting instance (e.g., a reporting instance related to a second CSI reporting). Optionally, M refers to the total number of measurements used to determine the BAI in a reporting instance. Optionally, M (or the value of M) can be indicated by the base station, or predefined, or determined based on UE capabilities. For example, the value of M can be one of 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 32. For example, M can be indicated by at least one of RRC, MAC-CE, and DCI. For example, M can be indicated by the second CSI reporting configuration.
[0225] The above method enables the UE to obtain the value of M, so that the UE can obtain the corresponding beam accuracy by reporting the number (m) of measurements with true / false results, thereby saving the overhead of CSI reporting.
[0226] The following describes another method for determining CSI (e.g., BAI). Optionally, the value of BAI is determined by quantization of at least one of the following: Here, the descriptions of X, k, M, and m are as above. Here, the value of BAI is called p. Optionally, p is an integer. Optionally, p ≥ 0. The following uses... Let's take an example to describe it. For example... The description also applies to or, or,

[0231] The following describes another method for determining the CSI (e.g., BAI). Optionally, the BAI may include X bits. For example, the BAI includes a bit sequence: b1, b2, ..., b X Optionally, b1 can be the least significant bit (LSB). X It can be the Most Significant Bit (LSB). Optionally, b x This corresponds to the comparison result reported by the first CSI for the x-th time. Optionally, 1 ≤ x ≤ X. For example, b x The first value (e.g., 1) indicates that the comparison result of the xth first CSI report (out of X first CSI reports) is true. For example, b x The second value (e.g., 0) indicates that the comparison result of the xth first CSI report (out of X first CSI reports) is false. See above for the comparison method associated with the first CSI reports.
[0232] The above method enables the UE to indicate the comparison result of each of the X first CSI reports, so that the base station can perform model management accordingly, thereby improving the performance of the communication system.
[0233] The resource corresponding to the resource indicator is a resource in the first resource set, and the resource determined by measuring all resources in the third resource set is also a resource in the third resource set. To facilitate the comparison between the resource corresponding to the resource indicator and the resources in the third resource set (and to determine the comparison result), it is necessary to provide the mapping relationship between the resources in the first and third resource sets, and to clarify the comparison operation used to determine the CSI, in order to ensure the reliability of the communication system.

[0236] ● The position of a resource in the first resource set is the same as the position of a resource in the third resource set. For example, the k-th resource in the first resource set is the same as the k-th resource in the third resource set. For example, if the first and third resource sets contain the same number of resources, then the k-th resource in the first resource set is the same as the k-th resource in the third resource set.
[0237] ● The positions of resources in the first resource set and the positions of resources in the third resource set satisfy a specific relationship. For example, the i-th resource in the first resource set and the i-th resource in the third resource set satisfy a specific relationship. The resources are the same. For example, if the first resource set and the third resource set contain different numbers of resources, then the i-th resource in the first resource set is the same as the i-th resource in the third resource set. The resources are identical. See below for a description of D.

[0243] ● The position of a resource in the first resource set within the first resource set is different from the position of a resource in the third resource set within the third resource set. For example, if a resource in the first resource set is the k-th resource in the first resource set and a resource in the third resource set is the j-th resource in the third resource set, and k ≠ j, then these two resources can be considered different. For example, the k-th resource in the first resource set is different from the j-th resource in the third resource set, where k ≠ j. For example, if the first and third resource sets contain the same number of resources, then the k-th resource in the first resource set is not different from the j-th resource in the third resource set, where k ≠ j.
[0244] ● The position of a resource in the first resource set within the first resource set does not satisfy a specific relationship with the position of a resource in the third resource set within the third resource set. For example, the i-th resource in the first resource set is different from the j-th resource in the third resource set. For example, if the first resource set and the third resource set contain different numbers of resources, and the i-th resource in the first resource set is different from the j-th resource in the third resource set, then...

Optionally, different reference signals can be: different reference signal IDs. Optionally, different reference signal types.
[0247] ● Resources in the first resource set are not mapped to resources in the third resource set.

For example, the first resource set includes {resource #1, resource #2, resource #3}, and the third resource set includes {resource #4, resource #5}, wherein the base station indicates that resource #4 is mapped to resources #1 and resource #2, and resource #5 is mapped to resource #3.
[0256] Optionally, the N1 resources in the third resource set can be mapped to resources in the first resource set corresponding to the N1 resource indicators in the (predicted) first CSI report. Optionally, for a single measurement associated with the third resource set, the N1 resources in the third resource set can be mapped to resources in the first resource set corresponding to the N1 resource indicators in the (predicted) first CSI report. Optionally, N1 ≤ K M Optionally, the N1 resources in the third resource set can be the first N1 (or last N1) resources in the third resource set. Here, the first N1 (or last N1) resources are determined based on the order of resource IDs (e.g., ascending / descending). Alternatively, the first N1 (or last N1) resources are determined based on the order (e.g., ascending / descending) of one or more resource configuration information corresponding to the third resource set. Optionally, the nth resource of the N1 resources in the third resource set is mapped to the resource corresponding to the nth resource indicator in the N1 resource indicators of the first CSI report. Optionally, the measurement of the third resource set is performed after the first CSI report (e.g., the time-domain resource where the first CSI report is located). Optionally, the time-domain offset between the measurement of the third resource set and the first CSI report (e.g., the time-domain resource where the first CSI report is located) is greater than or equal to a specific threshold. Optionally, the N1 resources in the third resource set are determined based on the most recent first CSI report preceding the corresponding measurement of the third resource set. Optionally, the N1 resources in the third resource set are determined based on the most recent first CSI report prior to a specific threshold for the corresponding measurement of the third resource set. Optionally, this specific threshold can be predefined or configured by the base station. Optionally, this specific threshold can be indicated by at least one of RRC, MAC-CE, and DCI. In this method, the beam corresponding to the measured resource in the third resource set is determined based on the first CSI report; therefore, the base station needs to process it after receiving the relevant CSI report. Thus, the corresponding measurement occurs either after the first CSI report or after the specific threshold of the first CSI report.
[0257] The following discussion outlines the method for determining the X first CSI reports. This method enables the base station to correctly understand which first CSI reports are being monitored in the second CSI reports, allowing the base station to adjust its UE-side model based on the reported monitoring results, thereby improving the reliability of the communication system.
[0258] Optionally, the X first CSI reports can be X first CSI reports that are no later than the second CSI report. Optionally, X first CSI reports that are no later than the second CSI report means that the time domain unit in which the X first CSI reports are located is no later than the time domain unit in which the second CSI report is located. In this document, the term "no later than" can be used interchangeably with the term "earlier than". Optionally, the X first CSI reports can be X first CSI reports that are earlier than the second CSI report. Optionally, X first CSI reports that are earlier than the second CSI report means that the time domain unit in which the X first CSI reports are located is earlier than the time domain unit in which the second CSI report is located. Optionally, the X first CSI reports can be the X first CSI reports closest to the second CSI report. Optionally, the X first CSI reports can be the X most recent first CSI reports preceding the second CSI report. Optionally, the X first CSI reports can be the X most recent first CSI reports that are no later than the second CSI report. Optionally, the X first CSI reports can be the X most recent first CSI reports prior to the second CSI report (relative to the second CSI report, or, relative to the time domain unit where the second CSI report is located). Optionally, the X first CSI reports can be the X most recent first CSI reports that are no later than the second CSI report (relative to the second CSI report, or, relative to the time domain unit where the second CSI report is located). Optionally, the X first CSI reports can be the X most recent first CSI reports relative to the time domain unit where the second CSI report is located.
[0259] Optionally, when the second CSI report is an aperiodic CSI report, the second CSI report can be triggered / scheduled / indicated by the DCI. Optionally, X first CSI reports refer to: X first CSI reports prior to the DCI, or X first CSI reports no later than the DCI.

[0262] ●The second CSI report is triggered / scheduled by DCI.
[0263] Optionally, X first CSI reports refer to X first CSI reports that are no later than or earlier than the second CSI report. Optionally, when the second condition is met, X first CSI reports refer to X first CSI reports that are no later than or earlier than the second CSI report. Optionally, when the second condition is met, X first CSI reports refer to the X most recent first CSI reports that are no later than or earlier than the second CSI report. Optionally, when the second condition is met, X first CSI reports refer to X first CSI reports that are no later than or earlier than the most recent X first CSI reports that are earlier than the second CSI report. Optionally, when the second condition is met, X first CSI reports refer to X first CSI reports that are no later than or earlier than the CSI reference resource corresponding to the second CSI report. Optionally, when the second condition is met, the X first CSI reports refer to: either the X most recent first CSI reports of the CSI reference resource corresponding to the second CSI report, or the X most recent first CSI reports of the CSI reference resource corresponding to the second CSI report. Optionally, the second condition includes at least one of the following:

[0266] Optionally, X first CSI reports refer to X first CSI reports within a window. Optionally, the temporal location of a window can be determined by the length of the window and / or the start point (e.g., the starting temporal resource) and / or the end point (e.g., the ending temporal resource).
[0267] Optionally, the window length can be indicated by the base station, or the window length can be predefined. For example, the base station can indicate the number of time-domain units associated with / corresponding to the window length through at least one of RRC signaling, MAC-CE, and DCI. Optionally, the window length can be determined based on the CSI reporting period associated with the first CSI reporting configuration and / or the period associated with the third resource set. Optionally, when the first CSI reporting is periodic CSI reporting, and / or the resources included in the third resource set are SSB or semi-persistent / periodic CSI-RS, the window length is determined based on the CSI reporting period associated with the first CSI reporting configuration and / or the period associated with the third resource set. Optionally, the window length is determined based on the longer / shorter period of the CSI reporting period associated with the first CSI reporting configuration and the period associated with the third resource set. Optionally, the window length is determined based on the maximum / minimum value of the CSI reporting period associated with the first CSI reporting configuration and the period associated with the third resource set.
[0268] Optionally, the start time domain resource / end time domain resource of the window is determined based on at least one of the following:
[0269] ● Indications from the base station. For example, indications regarding the configuration reported by the second CSI;
[0270] ●The time domain resource where the second CSI is reported, or the time domain resource where the corresponding CSI reference resource of the second CSI is reported;
[0271] ● Window length. See above for how to determine the window length;
[0272] ●The CSI reporting cycle associated with the first CSI reporting configuration;
[0273] ●The period associated with the third resource set is determined.
[0274] Optionally, the starting / ending time-domain resources of the window are determined based on the time-domain resources where the second CSI report is located and / or the indication from the base station. For example, the distance between the starting / ending time-domain resources of the window and the time-domain resources where the second CSI report is located is predefined or indicated by the base station. For example, the distance between the starting / ending time-domain resources of the window and the time-domain resources of the channel carrying the second CSI report (e.g., the first time-domain resource, or the last time-domain resource) is predefined or indicated by the base station. For example, the time-domain resource offset between the starting / ending time-domain resources of the window and the time-domain resources where the second CSI report is located is Y, where Y can be predefined or indicated by the base station. For example, the value of Y can be one of 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 32. For example, Y can be indicated by at least one of RRC, MAC-CE, and DCI. For example, when the time domain resource where the second CSI report is located is time slot n, the time domain resource where the start time domain resource / end time domain resource of this window is located is time slot nY or n+Y.
[0275] Optionally, the starting / ending time-domain resources of the window are determined based on the time-domain resources of the CSI reference resource corresponding to the second CSI report and / or the indication from the base station. For example, the distance between the starting / ending time-domain resources of the window and the time-domain resources of the CSI reference resource corresponding to the second CSI report is predefined or indicated by the base station. For example, the distance between the starting / ending time-domain resources of the window and the time-domain resources of the CSI reference resource corresponding to the second CSI report (e.g., the first time-domain resource, or the last time-domain resource) is predefined or indicated by the base station. For example, the time-domain resource offset between the starting / ending time-domain resources of the window and the time-domain resources of the CSI reference resource corresponding to the second CSI report is Z, where Z can be predefined or indicated by the base station. For example, the value of Z can be one of 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 32. For example, Z can be indicated by at least one of RRC, MAC-CE, and DCI. For example, when the time domain resource corresponding to the CSI reference resource of the second CSI report is time slot n, the time domain resource of the starting / ending time domain resource of the window associated with the second CSI report is time slot nZ or n+Z. Optionally, the starting / ending time domain resource of the window is determined based on the time domain resource of the second CSI report and / or the CSI reporting period associated with the first CSI report configuration and / or the period associated with the third resource set. The CSI reporting period associated with the first CSI report configuration and / or the period associated with the third resource set can be the maximum / minimum value of the CSI reporting period associated with the first CSI report configuration and the period associated with the third resource set. Optionally, the time slot number of the starting / ending time domain resource of the window is n*P, where P is determined based on the CSI reporting period associated with the first CSI report configuration and / or the period associated with the third resource set. For example, P is the number of time slots corresponding to the CSI reporting period associated with the first CSI report configuration. Here, n is an integer. The slot number associated with the start time domain resource / end time domain resource of the window is n*P, where n is the slot that minimizes the offset between the slot corresponding to n*P and the slot where the second CSI report is located.
[0276] Optionally, the N1 resources associated with the first CSI report (e.g., resources corresponding to the N resource indicators) are mapped to resources in the third resource set. Optionally, one (or each) of the X CSI reports is mapped to the N1 resources associated with the first CSI report and to resources in the third resource set. Optionally, the X CSI reports satisfy the following condition: at least one (or each) of the X CSI reports is mapped to the N1 resources associated with the first CSI report and to resources in the third resource set. Optionally, the mapping of the N1 resources associated with the first CSI report and to resources in the third resource set means that at least one resource among the N1 resources associated with the first CSI report (e.g., at least one resource among the resources corresponding to the N1 resource indicators) is mapped to resources in the third resource set. Optionally, the mapping of the resources in the first CSI report and to resources in the third resource set means that each resource among the N1 resources reported in the first CSI report (e.g., each resource among the resources corresponding to the N1 resource indicators) is mapped to resources in the third resource set. See other sections of this document for a description of the resource mapping method. For example, X first CSI reports refer to the most recent X first CSI reports that map each of the N1 reported resources (e.g., each of the resources corresponding to the N1 resource indicators) to the resources in the third resource set no later than the CSI reference resource corresponding to the second CSI report.
[0277] Optionally, if one (or each) of the X CSI reports is not mapped to a resource in the third resource set, then the second CSI report is not sent (or the second CSI report is discarded). Optionally, "the first CSI report is not mapped to a resource in the third resource set" means that at least one of the N1 resources reported in the first CSI report (e.g., at least one resource corresponding to one of the N1 resource indicators) is not mapped to a resource in the third resource set. Optionally, "the first CSI report is not mapped to a resource in the third resource set" means that each of the N1 resources reported in the first CSI report (e.g., each resource corresponding to one of the N1 resource indicators) is not mapped to a resource in the third resource set. This method allows the UE to avoid reporting when the predicted beam associated with the X CSI reports is not mapped to a resource in the resource set used for monitoring, since the comparison result is already known to the base station, thus saving UE energy consumption and improving the efficiency of the communication system.
[0278] The following discussion focuses on the method for determining the measurement of the third resource set. This method enables the UE to compare the measurement results of the first CSI report with those of a monitoring set more closely related to the reporting time domain, thereby improving the timeliness and accuracy of performance monitoring.
[0279] Optionally, the measurement of the third resource set can refer to: the measurement result of the third resource set. Optionally, the measurement of the third resource set can refer to: the measurement of the transmission opportunity of resources in the third resource set, and / or, the measurement of resources in the third resource set, and / or, the measurement of all resources in the third resource set. Here, each CSI report in the X first CSI reports can be compared with the measurement of the third resource set. Each CSI report in the X first CSI reports can be compared with the associated / corresponding measurement of the third resource set. Here, transmission opportunity can be considered as measurement opportunity. In this document, the term "resource opportunity" can be used interchangeably with the terms "resource transmission opportunity" or "resource measurement" or "resource measurement opportunity". Optionally, the transmission opportunity associated with the xth (1≤x≤X)th CSI report in the X first CSI reports can be at least one of the following:
[0280] ● The transmission opportunity for resources in the third resource set reported by the second CSI no later than (or earlier than) the most recent transmission opportunity for resources in the third resource set reported by the second CSI. For example, the transmission opportunity for resources in the x-th most recent third resource set reported by the second CSI.
[0281] ● A transmission opportunity no later than (or earlier than) the resource in the third resource set corresponding to the CSI reference resource reported by the second CSI; for example, the most recent transmission opportunity of the resource in the third resource set corresponding to the CSI reference resource reported by the second CSI. For example, the transmission opportunity of the resource in the x-th nearest third resource set corresponding to the CSI reference resource reported by the second CSI;
[0282] ● The nearest transmission opportunity for a resource in the third resource set. For example, the transmission opportunity for a resource in the third resource set closest to the x-th CSI report. Optionally, the distance between the x-th CSI report and the transmission opportunity for the resource can be: the distance between the time-domain resource where the x-th CSI report is located and the time-domain resource where the transmission opportunity for the resource is located. Optionally, the distance between the x-th CSI report and the transmission opportunity for the resource can be: the distance between the time-domain unit of the channel carrying the CSI report and the time-domain unit of the transmission opportunity for the resource. Optionally, the distance between the x-th CSI report and the transmission opportunity for the resource can be: the distance between the first (or last) time-domain unit of the channel carrying the CSI report and the first (or last) time-domain unit of the transmission opportunity for the resource. Optionally, the distance between the x-th CSI report and the transmission opportunity for the resource can be: the distance between the first (or last) time-domain unit of the channel carrying the CSI report and the first (or last) time-domain unit of the transmission opportunity for the resource. For example, if the CSI report precedes the resource transmission opportunity, the distance is the distance between the last time-domain unit of the channel carrying the CSI report and the first time-domain unit of the resource transmission opportunity. If the CSI report follows the resource transmission opportunity, the distance is the distance between the first time-domain unit of the channel carrying the CSI report and the last time-domain unit of the resource transmission opportunity. Here, the distance can be an offset of the time-domain resource. Optionally, if two transmission opportunities have the same distance as a CSI report, the later transmission opportunity is used for comparison. Here, the unit of time-domain resource can be a timeslot or a symbol.
[0283] ● The nearest transmission opportunity for a resource in the third resource set. For example, the transmission opportunity for a resource in the third resource set that is closest to the CSI reference resource corresponding to the x-th CSI report. Optionally, the distance between the CSI reference resource corresponding to the x-th CSI report and the transmission opportunity of the resource can be: the distance between the time domain resource where the CSI reference resource corresponding to the x-th CSI report is located and the time domain resource where the transmission opportunity of the resource is located. Optionally, the distance between the CSI reference resource corresponding to the x-th CSI report and the transmission opportunity of the resource can be: the distance between the time domain unit of the CSI reference resource corresponding to the x-th CSI report and the time domain unit of the transmission opportunity of the resource. Optionally, the distance between the CSI reference resource corresponding to the x-th CSI report and the transmission opportunity of the resource can be: the distance between the first time domain unit (or, the last time domain unit) where the CSI reference resource corresponding to the x-th CSI report is located and the first time domain unit (or, the last time domain unit) where the transmission opportunity of the resource is located. Optionally, the distance between the CSI reference resource corresponding to the x-th CSI report and the transmission opportunity of the resource can be: the distance between the first time domain unit (or, the last time domain unit) of the CSI reference resource corresponding to the x-th CSI report and the first time domain unit (or, the last time domain unit) of the transmission opportunity of the resource. For example, if the CSI reference resource corresponding to the CSI report is before the transmission opportunity of the resource, then the distance is the distance between the last time domain unit of the CSI reference resource corresponding to the CSI report and the first time domain unit of the transmission opportunity of the resource. If the CSI reference resource corresponding to the CSI report is after the transmission opportunity of the resource, then the distance is the distance between the first time domain unit of the channel carrying the CSI report and the last time domain unit of the transmission opportunity of the resource. Here, the distance can be an offset of the time domain resource. Optionally, if the distances between two transmission opportunities and the CSI reference resource corresponding to a CSI report are equal, the later transmission opportunity is used for comparison. Optionally, if the distances between two transmission opportunities and a CSI report are equal, the earlier transmission opportunity is used for comparison. Here, the unit of time-domain resources can be a time slot or a symbol.
[0284] Optionally, the measurement of the third resource set may refer to: a measurement of the third resource set within a window associated with a first CSI report. Optionally, the measurement of the third resource set may refer to: a measurement of the transmission opportunity of resources in the third resource set, and / or, a measurement of resources in the third resource set. Here, each CSI report in the X first CSI reports can be compared with a measurement of the third resource set within the window. Each CSI report in the X first CSI reports can be compared with a measurement of the third resource set within the associated / corresponding window. Here, a transmission opportunity can be considered a measurement opportunity. The temporal position of a window can be determined by the length of the window and the window's start point (e.g., the starting temporal resource) and / or end point (e.g., the ending temporal resource). The window associated with the first CSI report is described below.
[0285] Optionally, the length of the window associated with the x-th (1≤x≤X) CSI report in the X first CSI reports is indicated by the base station. For example, the base station indicates the number of time-domain units associated with / corresponding to the length of the window through at least one of RRC signaling, MAC-CE, and DCI. Optionally, the length of the window associated with the x-th (1≤x≤X) CSI report in the X first CSI reports is determined based on the CSI reporting period associated with the first CSI reporting configuration and / or the period associated with the third resource set. Optionally, when the first CSI report is a periodic CSI report, and / or the resources included in the third resource set are SSB or semi-persistent / periodic CSI-RS, the length of the window associated with the x-th (1≤x≤X) CSI report in the X first CSI reports is determined based on the CSI reporting period associated with the first CSI reporting configuration and / or the period associated with the third resource set. Optionally, the length of the window associated with the x-th (1≤x≤X) CSI report among the X first CSI reports is determined based on the longer / shorter period between the CSI reporting period associated with the first CSI reporting configuration and the period associated with the third resource set. Optionally, the length of the window associated with the x-th (1≤x≤X) CSI report among the X first CSI reports is determined based on the maximum / minimum value between the CSI reporting period associated with the first CSI reporting configuration and the period associated with the third resource set. For example, the length of the window associated with the x-th (1≤x≤X) CSI report among the X first CSI reports is a*P. Optionally, P can correspond to the period associated with the third resource set, or the CSI reporting period associated with the first CSI reporting configuration, or the maximum / minimum period between the period associated with the third resource set and the CSI reporting period associated with the first CSI reporting configuration. Here, a can be a scaling factor. The value of 'a' can be one of 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, or 32. Optionally, 'a' can be predefined. Optionally, 'a' can be indicated by the base station. For example, 'a' can be indicated by at least one of RRC signaling, MAC-CE, or DCI. Here, the CSI reporting period associated with the CSI reporting configuration refers to the CSI reporting period corresponding to the CSI reporting configuration. For example, if the CSI reporting corresponding to the CSI reporting configuration is periodic or semi-persistent, then the CSI reporting configuration includes the reporting slot configuration parameter 'reportSlotConfig', which can indicate the CSI reporting period. Here, the period associated with the third resource set refers to the period of the resources in the third resource set. For example, when the third resource set includes semi-persistent / periodic CSI-RS, the period associated with the third resource set refers to the period of the CSI-RS. For example, when the third resource set includes SSB, the period associated with the third resource set refers to the period of the SSB.
[0286] Optionally, the start-time domain resource / end-time domain resource of the window associated with the xth (1≤x≤X) CSI report in the X first CSI reports is determined based on at least one of the following:
[0287] ● Indications from the base station. For example, indications regarding the configuration reported by the second CSI;
[0288] ●The time domain resource where the xth CSI report is located, or the time domain resource where the CSI reference resource corresponding to the xth CSI report is located;
[0289] ● Window length. See above for how to determine the window length;
[0290] ●The CSI reporting cycle associated with the first CSI reporting configuration;
[0291] ●The period associated with the third resource set is determined.
[0292] Optionally, the starting / ending time-domain resource of the window associated with the xth (1≤x≤X)th CSI report in the X first CSI reports is determined based on the time-domain resource where the xth CSI report is located and / or the indication from the base station. For example, the distance between the starting / ending time-domain resource of the window associated with the xth (1≤x≤X)th CSI report in the X first CSI reports and the time-domain resource where the CSI report is located is predefined or indicated by the base station. For example, the distance between the starting / ending time-domain resource of the window associated with the xth (1≤x≤X)th CSI report in the X first CSI reports and the time-domain resource of the channel carrying the CSI report (e.g., the first time-domain resource, or the last time-domain resource) is predefined or indicated by the base station. For example, the time-domain resource offset between the starting / ending time-domain resource of the window associated with the xth CSI report and the time-domain resource where the CSI report is located is Y, where Y can be predefined or indicated by the base station. For example, the value of Y can be one of 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, or 32. For example, Y can be indicated by at least one of RRC, MAC-CE, or DCI. For example, when the time domain resource where the x-th CSI report is located is time slot n, the time domain resource where the start / end time domain resource of the window associated with the x-th CSI report is located is time slot nY or n+Y.
[0293] Optionally, the starting / ending time-domain resource of the window associated with the xth (1≤x≤X)th CSI report in the X first CSI reports is determined based on the time-domain resource of the CSI reference resource corresponding to the xth CSI report and / or the indication from the base station. For example, the distance between the starting / ending time-domain resource of the window associated with the xth (1≤x≤X)th CSI report in the X first CSI reports and the time-domain resource of the CSI reference resource corresponding to the xth CSI report is predefined or indicated by the base station. For example, the distance between the starting / ending time-domain resource of the window associated with the xth (1≤x≤X)th CSI report in the X first CSI reports and the time-domain resource of the CSI reference resource corresponding to the xth CSI report (e.g., the first time-domain resource, or the last time-domain resource) is predefined or indicated by the base station. For example, the time domain resource offset between the start / end time domain resource of the window associated with the xth CSI report and the time domain resource of the CSI reference resource corresponding to the xth CSI report is Z, where Z can be predefined or indicated by the base station. For example, the value of Z can be one of 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 32. For example, Z can be indicated by at least one of RRC, MAC-CE, and DCI. For example, when the time domain resource of the CSI reference resource corresponding to the xth CSI report is time slot n, the time domain resource of the start / end time domain resource of the window associated with the xth CSI report is time slot nZ or n+Z. Optionally, the start / end time domain resource of the window associated with the xth (1≤x≤X) of the X first CSI reports is determined based on the time domain resource of the xth CSI report and / or the CSI reporting period associated with the first CSI report configuration and / or the period associated with the third resource set. The CSI reporting period associated with the first CSI reporting configuration and / or the period associated with the third resource set can be the maximum / minimum value of the CSI reporting period associated with the first CSI reporting configuration and the period associated with the third resource set. Optionally, the slot number of the starting time domain resource / ending time domain resource of the x-th CSI reporting associated window is n*P, where P is determined based on the CSI reporting period associated with the first CSI reporting configuration and / or the period associated with the third resource set. For example, P is the number of slots corresponding to the CSI reporting period associated with the first CSI reporting configuration. Here, n is an integer. The slot number of the starting time domain resource / ending time domain resource associated with the x-th (1≤x≤X)-th CSI reporting associated window is n*P, where n is the n that minimizes the offset between the slot corresponding to n*P and the slot where the first CSI reporting is located. Optionally, if there is more than one n that minimizes the offset between the slot corresponding to n*P and the slot where the first CSI reporting is located, the window corresponding to the smaller / larger n value is used for comparison.
[0294] The following discussion outlines the method for determining the M measurements associated with the third resource set. This method enables the base station to correctly understand which measurements associated with the third resource set correspond to the CSI reported in the second CSI report. This allows the base station to adjust the UE-side model based on the reported monitoring results, improving the reliability of the communication system. Furthermore, the M measurements associated with the third resource set can be used to determine the BAI (Balance of Artificial Intelligence), as described above.
[0295] Optionally, the measurement of the third resource set can refer to: the measurement result of the third resource set. Optionally, the measurement of the third resource set can refer to: the measurement of the transmission opportunity of resources in the third resource set, and / or, the measurement of resources in the third resource set, and / or, the measurement of all resources in the third resource set. Here, transmission opportunity can be considered as measurement opportunity. In this document, the term "resource opportunity" can be used interchangeably with the terms "resource transmission opportunity," "resource measurement," or "resource measurement opportunity."
[0296] Optionally, the M measurements associated with the third resource set refer to the M most recent measurements associated with the third resource set. Alternatively, the M measurements associated with the third resource set refer to the M most recent measurements associated with the third resource set. Alternatively, the M measurements associated with the third resource set refer to the M most recent measurements associated with the third resource set no later than those reported by the second CSI to the corresponding CSI reference resource. Alternatively, the M measurements associated with the third resource set refer to the M most recent measurements associated with the third resource set no later than those reported by the second CSI. Optionally, M can be equal to X. For example, M = X.
[0297] Optionally, the M measurements associated with the third resource set refer to: measurements in a window associated with the M third resource sets.
[0298] Optionally, the M measurements associated with the third resource set refer to the measurements associated with the third resource set within the M windows.

Optionally, the latest window among the M windows is no later than the second CSI report. Optionally, the latest window among the M windows is no later than the CSI reference resource corresponding to the second CSI report. Optionally, at least one of the M windows includes the first CSI report. Optionally, each of the M windows includes the first CSI report. Optionally, the M windows satisfy the following condition: at least one (or each) of the M windows includes the first CSI report.

Optionally, the method for determining the window associated with the measurement associated with the third resource set can be found above. Optionally, the length of the window associated with the m1th measurement among the M measurements associated with the third resource set is indicated by the base station. For example, the base station indicates the number of time-domain units associated / corresponding to the length of the window through at least one of RRC signaling, MAC-CE, and DCI. Optionally, the length of the window is determined based on the CSI reporting period associated with the first CSI reporting configuration and / or the period associated with the third resource set. Optionally, when the first CSI reporting is a periodic CSI reporting, and / or the resources included in the third resource set are SSBs or semi-persistent / periodic CSI-RS, the length of the window is determined based on the CSI reporting period associated with the first CSI reporting configuration and / or the period associated with the third resource set.

Optionally, the window length is determined based on the maximum / minimum value of the CSI reporting period associated with the first CSI reporting configuration and the period associated with the third resource set. For example, the window length is a*P. Optionally, P can correspond to the period associated with the third resource set, or the CSI reporting period associated with the first CSI reporting configuration, or the maximum / minimum period among the period associated with the third resource set and the CSI reporting period associated with the first CSI reporting configuration.

For example, a can be indicated by at least one of RRC signaling, MAC-CE, or DCI. Here, the CSI reporting period associated with the CSI reporting configuration refers to the CSI reporting period corresponding to the CSI reporting configuration.

Here, the period associated with the third resource set refers to the period of the resources in the third resource set. For example, when the third resource set includes semi-persistent / periodic CSI-RS, the period associated with the third resource set refers to the period of the CSI-RS. For example, when the third resource set includes SSB, the period associated with the third resource set refers to the period of the SSB.

[0321] Optionally, the starting / ending time-domain resource of the window associated with the m1th measurement among the M measurements associated with the third resource set is determined based on the time-domain resource associated with the m1th measurement and / or the indication from the base station. For example, the distance between the starting / ending time-domain resource of the window associated with the m1th measurement and the time-domain resource where the transmission opportunity of the m1th measurement is located is predefined or indicated by the base station. For example, the distance between the starting / ending time-domain resource of the window associated with the m1th measurement and the time-domain resource associated with / located to the transmission opportunity of the m1th measurement (e.g., the first time-domain resource, or the last time-domain resource) is predefined or indicated by the base station. For example, the time-domain resource offset between the starting / ending time-domain resource of the window associated with the m1th measurement and the time-domain resource where the transmission opportunity of the m1th measurement is located is Y, where Y can be predefined or indicated by the base station. For example, the value of Y can be one of 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 32. For example, Y can be indicated by at least one of RRC, MAC-CE, and DCI.

The L1-RSRPs are determined based on the mapped / corresponding CRIs / SSBRIs.When the first resource set is configured, CRI / SSBRI corresponds to the resources in the first resource set. See above for details on the correspondence. When the first resource set is not configured, CRI / SSBRI corresponds to the resources in the second resource set. Optionally, the relationship between CRI / SSBRI and the resources in the second resource set is as follows:

[0325] ●In this article, the second resource set can also be a second set, where the second set includes K. B A set of elements. The description of "resources" can be equivalently applied to the description of "elements" in the second set.
[0326] The following further explains time instances. Optionally, a time instance can be a point in time or a time period. Optionally, a time period can include one or more time domain units.

Optionally, a point in time can be defined by a time domain unit. For example, a point in time can be the beginning or the end of a time domain unit. The time domain unit associated with a time period or point in time (e.g., the start time domain unit, or the end time domain unit, or the time domain unit used to define the point in time) can be referred to as the time domain unit associated with the time instance. Optionally, a time domain unit can be one of a symbol, a time slot, a sub-time slot, a subframe, a millisecond, or a second. Optionally, the F time instances can be determined based on time domain information. Optionally, CSI reporting configuration associates / includes / configures parameters used to indicate time domain information. Optionally, the time domain information is used for prediction.

Optionally, the time domain unit associated with the reference time domain resource can be the first (or last) time domain unit where the reference time domain resource is located. Optionally, the time domain unit where the f-th / f-earliest time instance among the F time instances is located is time domain unit n + F_D + (f-1) * F_offset. Optionally, 1 ≤ f ≤ F. Optionally, the f-th time instance among the F time instances is determined based on the temporal order of the time domain units associated with the time instances (e.g., from front to back, or from back to front). For example, time instance #1 is associated with time slot #3, time instance #2 is associated with time slot #2, and time instance #3 is associated with time slot #5, where the second time instance is time instance #2. F_D can be the offset between the reference time domain resource and the time instance. j This can be the offset between the reference time-domain resource and the j-th time instance. Optionally, F_D can be indicated by the base station, or it can be predefined, or it can be determined based on UE capabilities. For example, the value of F_D can be indicated by at least one of RRC, MAC-CE, and DCI. Optionally, F_D j It can be indicated by the base station, or it can be predefined, or it can be determined based on the UE's capabilities. For example, F_D j The value of F_offset can be indicated by at least one of RRC, MAC-CE, and DCI. Optionally, F_offset can be indicated by the base station, or it can be predefined, or it can be determined based on the UE's capabilities.

The length of the time instance can be: the number of time domain elements occupied by the time instance, or the number of time domain elements included in the time instance.
[0330] Optionally, the UE may report X (X≥1) first CSI reports associated with the first CSI reporting configuration. Optionally, the UE may report X (X≥1) first CSI reports for inference / prediction. Optionally, the UE may report X (X≥1) first CSI reports for reporting inference / prediction CSIs.

Here, the resource indicators can be SSBRIs and / or CRIs. Optionally, the resource indicator corresponds to a resource in a first resource set, or the resource indicator corresponds to a resource in a second resource set. See above for the corresponding method. Optionally, the N1 resource indicators may indicate / correspond to the best N1 resources (top / best N1resource(s)) in the first resource set / second resource set. Optionally, the N1 resource indicators can indicate the strongest N1 resources(s) in the first resource set / second resource set.

Optionally, X can be related to UE capabilities. For example, the value of X is less than or equal to the maximum value indicated by UE capability signaling.
[0331] Optionally, the period of the CSI reporting corresponding to the first CSI reporting configuration associated with the second CSI reporting configuration can be the same as the period of the resources in the third resource set associated with the second CSI reporting configuration. Optionally, this method is applicable when the CSI reporting corresponding to the first CSI reporting configuration is periodic CSI reporting and / or semi-persistent CSI reporting. Optionally, this method is applicable when the resources associated with the third resource set of the second CSI reporting configuration are periodic resources (e.g., periodic CSI-RS resources and / or SSB resources) or semi-persistent resources (e.g., semi-persistent CSI-RS resources). This method allows for a one-to-one correspondence between the CSI reporting opportunities used for model inference and the transmission opportunities of the resources used for model monitoring, facilitating comparison by the UE, reducing the complexity of CSI calculation by the UE, and thus reducing the hardware cost of the UE.
[0332] Optionally, the UE may determine and / or report CSIs based on the second CSI reporting configuration. Optionally, the UE may report CSIs associated with the second CSI reporting configuration. Optionally, a report carrying a CSI associated with the second CSI reporting configuration may be referred to as a second CSI report. Optionally, the UE may report a second CSI report for monitoring. Optionally, the UE may report a second CSI report for reporting monitored CSIs. Optionally, the UE may determine and / or report CSI reports based on the second CSI reporting configuration. Optionally, the CSI associated with the second CSI reporting configuration may be a BAI. Optionally, the CSI associated with the second CSI reporting configuration (or, the CSIs included in the second CSI report) may be determined based on the following (or, a comparison of the following two):
[0333] ●Resources associated with resource indicators included in the CSIs associated with each of the X first CSI reports and each of the F time instances in the time instances;
[0334] ● Resources determined based on measurements of a third resource set. Optionally, resources determined based on measurements of a third resource set may be resources within a third resource set determined based on measurements of all resources within that third resource set. Optionally, resources determined based on measurements of a third resource set may be one or more resources within a third resource set determined based on measurements of all resources within that third resource set. Optionally, resources determined based on measurements of a third resource set may be one or more resources within a third resource set determined based on measurements of all resources within that third resource set.
[0335] The method described above for generating CSI for performance monitoring allows the UE to compare the CSI prediction results associated with time instances with the measurement results of the resource set used for monitoring. The comparison results are reflected in the CSI reporting, enabling the UE to report the CSI for performance monitoring. The CSI for performance monitoring facilitates the base station's acquisition of performance metrics from the UE-side model, enabling appropriate model management and improving the reliability of the UE-side AI model.
[0336] Optionally, the CSI associated with the second CSI report configuration (or the CSIs included in the second CSI report) can be determined by comparing the resources associated with the resource indicators in the CSIs associated with each of the F time instances included in each of the X first CSI reports with resources determined based on measurements of a third resource set (e.g., resources in the third resource set). Optionally, the measurement of the third resource set can be a measurement of resources in the third resource set. Optionally, the measurement of the third resource set can be a measurement of all resources in the third resource set.
[0337] Optionally, the above comparison can be: a comparison of the resource associated with at least one of the N1 resource indicators in the CSI associated with the f-th time instance of the x-th (1≤x≤X)-th CSI report among the X first CSI reports, and the resource determined based on measurements of a third resource set. Optionally, the f-th time instance refers to the f-th time instance among F time instances. Optionally, 1≤f≤F.
[0338] Optionally, the above comparison can be: (determining) whether the resources associated with the N1 resource indicators of the f-th time instance in the x-th CSI report among the X first CSI reports are among the N2 resources with the highest (measured) L1-RSRP in the third resource set determined based on measurements of the third resource set. For example, each resource indicator in the N1 resource indicators is associated with one resource. The UE compares whether the N1 resources associated with the N1 resource indicators of the f-th time instance in the x-th CSI report among the X first CSI reports are among the N2 resources with the highest (measured) L1-RSRP in the third resource set. This comparison method can be referred to as method #5A. Here, N1 resources in N2 resources can be considered as: all N1 resources are in N2 resources, or, every resource in N1 resources is in N2 resources. Here, N1 resources in N2 resources can be considered as: N1 resources in N2 resources are the same as the N1 resources. Optionally, N1 ≤ N2. The relevant description of N2 is provided below. For example, if the predicted resources are CSI-RS#1 and CSI-RS#2, and the three resources with the highest measured L1-RSRP in the third resource set are CSI-RS#1, CSI-RS#2, and CSI-RS#3, then the predicted resource is among the three resources with the highest measured L1-RSRP in the third resource set. Conversely, if the predicted resources are CSI-RS#1 and CSI-RS#2, and the three resources with the highest measured L1-RSRP in the third resource set are CSI-RS#2, CSI-RS#3, and CSI-RS#4, then the predicted resource is not among the three resources with the highest measured L1-RSRP in the third resource set. This method allows the UE to compare whether the optimal beam in the set for monitoring is within the UE's predicted beam. This helps the base station determine whether the beam prediction matches the actual measured beam, allowing the base station to make adjustments when the prediction deviates from the monitoring results, thus improving the reliability of the communication system.
[0339] Optionally, the above comparison can be: (determining) whether the resource with the highest (measured) L1-RSRP in the third resource set, determined based on measurements of the third resource set, is one of the resources associated with N1 resource indicators in the CSI associated with the f-th time instance of the x-th CSI report in the x-th first CSI reports. For example, each of the N1 resource indicators is associated with one resource. The UE compares whether the resource with the highest (measured) L1-RSRP in the third resource set is one of the N1 resources associated with the N1 resource indicators in the CSI associated with the f-th time instance of the x-th CSI report in the X-th first CSI reports. This comparison method can be referred to as method #5. Optionally, the resource associated with the N1 resource indicators can be: the resource associated with one of the N1 resource indicators. For example, one of the N1 resource indicators is associated with one resource. The UE compares whether the resource with the highest (measured) L1-RSRP in the third resource set is associated with one of the resource indicators in the N1 resource indicators of the CSI associated with the f-th time instance in the x-th CSI report of the first CSI report. This comparison method can be called Method #6. This method allows the UE to compare whether the optimal beam in the set for monitoring is in the beam predicted by the UE. This helps the base station determine whether the beam prediction matches the actual measured beam of the monitored beam, so that the base station can make corresponding adjustments when the prediction deviates from the monitoring results, thereby improving the reliability of the communication system.
[0340] Optionally, the above comparison can be: (determining) whether the resource associated with one of the N1 resource indicators in the CSI associated with the f-th time instance of the x-th CSI report in the X first CSI reports is one of the N2 (N2≥1) resources in the third resource set determined based on the measurement of the third resource set. Optionally, the N2 resource indicators can indicate / correspond to the best N2 resources in the third resource set. Optionally, the N2 resource indicators can indicate the strongest N1 resources in the third resource set. Optionally, the N2 resource indicators can indicate the N2 resources with the highest (measured) L1-RSRP in the third resource set. Optionally, N2 can be indicated by the base station. For example, N2 is indicated by at least one of RRC, MAC-CE, and DCI. N2 can be predefined. This comparison method can be referred to as method #7. This method allows the UE to compare whether the beam predicted by the UE is in the optimal set of beams in the monitoring set. This helps the base station determine whether the beam prediction matches the actual measured beam. In this way, the base station can make corresponding adjustments when the prediction deviates from the monitoring results, thereby improving the reliability of the communication system.
[0341] Optionally, the above comparison can be: (determining) whether the difference between the (measured) L1-RSRP of the resource associated with one of the resource indicators in the CSI associated with the f-th time instance of the x-th CSI report in the x-th first CSI report and the highest (measured) L1-RSRP determined based on measurements of the third resource set is less than a threshold. Here, the threshold can be expressed as T dB. Optionally, T ≥ 0. Optionally, T can be predefined. Optionally, the value of T can be one of 0, 1, 2, 3, 4, 5, 6, 7, 8. Optionally, the value of T can be indicated by the base station. For example, indicated by the configuration of the second CSI report. Optionally, the value of T can be determined based on UE capabilities. For example, the value of T can be determined based on the indication of the reported UE capability signaling. This comparison method can be referred to as method #8. This method allows the UE to compare the L1-RSRP of the predicted optimal beam with the L1-RSRP of the optimal beam in the monitoring set to see if they are within a certain range. This helps the base station determine whether the beam prediction matches the actual measured beam, so that the base station can make corresponding adjustments when the prediction deviates from the monitoring results, thereby improving the reliability of the communication system.
[0342] Optionally, the UE may make a comparison using one of the following methods: method #5A, method #5, method #6, method #7, or method #8, based on the base station's indication or a predefined method.
[0343] In the method described above, the description of one of the N1 resource indicators is as above. The description of one of the N1 resource indicators associated with the first resource set also applies to the second resource set.
[0344] The method for determining the CSI (e.g., BAI) is described below. Optionally, the value of BAI is indicated by the BAI field. BAI can be associated with one of the following methods:
[0345] ●Method #A: Optionally, the value k of BAI refers to: k CSI reports out of X first CSI reports have a comparison result that is true. Optionally, the value k of BAI refers to: the number of CSI reports out of X first CSI reports with a comparison result that is true. Optionally, k ≥ 0. Optionally, k ≤ X. Optionally, the value k of BAI refers to: the number of comparisons with true results associated with X first CSI reports. Optionally, the value k of BAI refers to: the number of CSIs with true results associated with X first CSI reports. Optionally, the value k of BAI refers to: the number of comparisons with true results associated with X first CSI reports. Here, CSI report can refer to the CSIs included in the CSI report (or, the inference results included in the CSI report). In this document, the term "CSI report" can be used interchangeably with the terms "CSIs included in the CSI report" or "inference results included in the CSI report". For example, the number of CSI reports can be considered as the number of inference results included in the CSI reports.
[0346] ●Method #B: Optionally, the value k of BAI refers to the number of time instances whose comparison result is true out of the X time instances associated with the first CSI reports (e.g., X*F time instances). Optionally, the value k of BAI refers to the number of time instances whose comparison result is true out of the X time instances associated with the first CSI reports (e.g., X*F time instances). Optionally, k ≥ 0. Optionally, k ≤ X*F.
[0347] ●Method #C: Optionally, the value k of BAI refers to: k time instances among the X first CSI reports associated with the f-th time instance (e.g., X time instances) whose comparison result is true. Optionally, the value k of BAI refers to: the number of time instances among the X first CSI reports associated with the time instances (e.g., X*F time instances) whose comparison result is true. Optionally, k≥0. Optionally, k≤X. Optionally, the second CSI report may include F BAIs. Optionally, the f-th BAI among the F BAIs is determined based on the comparison associated with the f-th time instance. Optionally, the f-th BAI among the F BAIs is determined based on the comparison associated with the f-th time instance of each CSI report in the X first CSI reports.
[0348] The following describes the method for determining the comparison result. Optionally, if A and B are the same, the comparison result of A and B can be considered true. If A and B are different, the comparison result of A and B can be considered false. For example, when at least one resource indicator in the CSI associated with the f-th time instance of the x-th CSI report in X first CSI reports is associated with a resource that is the same as / mapped to a resource determined based on a measurement of a third resource set, the comparison result can be considered true. For example, when at least one resource indicator in the CSI associated with the f-th time instance of the x-th CSI report in X first CSI reports is associated with a resource that is different from (or not mapped to) a resource determined based on a measurement of a third resource set, the comparison result can be considered false.
[0349] In this document, X first CSI reports can correspond to X CSI reporting opportunities. Optionally, the X first CSI reports can be the first CSI report among X CSI reporting opportunities. If a CSI report is not sent in a CSI reporting opportunity, the UE can assume that the comparison result corresponding to that CSI report is predefined. For example, the comparison result is true. For example, the comparison result is false. For example, for the calculation / determination of BAI, if a CSI report is not sent in a CSI reporting opportunity, the UE can assume that the comparison result corresponding to that CSI report is true. For example, for the calculation / determination of BAI, if a CSI report is not sent in a CSI reporting opportunity, the UE can assume that the comparison result corresponding to that CSI report is false. In this document, X first CSI reports can correspond to X CSI reporting opportunities. Optionally, the X first CSI reports can be the first CSI report among X CSI reporting opportunities. If a CSI report is not sent during a CSI reporting opportunity, the UE can assume that the comparison results for the F time instances associated with that CSI report are predefined. For example, the comparison result is true. Or, the comparison result is false. For example, for BAI calculation / determination, if a CSI report is not sent during a CSI reporting opportunity, the UE can assume that the comparison results for all time instances associated with that CSI report are true. For example, for BAI calculation / determination, if a CSI report is not sent during a CSI reporting opportunity, the UE can assume that the comparison results for all time instances associated with that CSI report are false. This method allows the UE and base station to have a shared understanding of the comparison results for a possible CSI report when the UE does not send a CSI report during a corresponding CSI reporting opportunity. This avoids the base station and UE interpreting the corresponding beam accuracy based on different comparison results for the CSI report, thus improving the reliability of the communication system.
[0350] When method #A or method #C is used, the accuracy of BAI is [percentage missing]. Optionally, the accuracy rate can be the accuracy rate reported by the first CSI. Optionally, the accuracy rate can be the accuracy rate of the inference results reported by the first CSI.

Optionally, when method #C is used, a comparison result of true for a first CSI report means: the comparison result of the f-th time instance associated with the first CSI report is true.
[0352] ● Optionally, the value k of BAI can refer to: the number of CSI reports with a false comparison result out of x first CSI reports. Alternatively, the value k of BAI can refer to the number of CSI reports with a false comparison result out of x first CSI reports. In this case, the accuracy corresponding to BAI is... Optionally, a false comparison result reported by the first CSI means that the comparison result of all associated time instances (e.g., F time instances) reported by the first CSI is false, or that the comparison result of at least one associated time instance reported by the first CSI is false.
[0353] ●Optionally, the size of the field of BAI (or the field corresponding to BAI) is Or log2X. Optionally, the size of the BAI field (or the field corresponding to BAI) is determined based on X+1. For example, the size of the BAI field (or the field corresponding to BAI) is equal to... Or, log2(X+1), or, or, Here, A can be an integer greater than or equal to 1. For example, A can be one of 1, 2, 3, 4, 5, 6, 7, or 8. Optionally, A can be predefined or A can be indicated / configured by the base station. Since the value range of BAI can be from 0 to X, that is, BAI can indicate X+1 values, determining the size of the BAI field based on X+1 can avoid some values from 0 to X not being indicated, thus improving the reliability of UE CSI reporting and consequently improving the reliability of the communication system.
[0354] When method #B is used, the accuracy of BAI is [percentage missing]. Optionally, the accuracy can be the accuracy of the CSI associated with the time instance in the first CSI report. Optionally, the accuracy can be the accuracy of the inference results associated with each time instance in the first CSI report.

Optionally, the accuracy can be the accuracy of the CSI associated with each time instance in the report of the configuration reported by the first CSI report. Optionally, the accuracy can be the accuracy of the (reported) inference associated with the configuration reported by the first CSI report. Optionally, the accuracy can be the accuracy of the (reported) inference results associated with the configuration reported by the first CSI report.
[0355] ● Optionally, the value k of BAI can refer to: k time instances among the X time instances associated with the first CSI reports (e.g., X*F time instances) have a comparison result of true. Optionally, the value k of BAI can refer to the number of time instances among the X time instances associated with the first CSI reports whose corresponding comparison result is true.
[0356] ● Optionally, the value k of BAI can refer to: among the X time instances associated with the first CSI reports (e.g., X*F time instances), k time instances have a comparison result of false. Alternatively, the value k of BAI can refer to the number of time instances with a comparison result of false among the X time instances associated with the first CSI reports. In this case, the accuracy corresponding to BAI is...
[0357] ●Optionally, the size of the field of BAI (or the field corresponding to BAI) is Alternatively, log2(F·X). Optionally, the size of the BAI field (or the field corresponding to BAI) is determined based on F·X+1. For example, the size of the BAI field (or the field corresponding to BAI) is equal to... Or, log2(F·X+1), or, or, Here, A can be an integer greater than or equal to 1. For example, A can be one of 1, 2, 3, 4, 5, 6, 7, or 8. Optionally, A can be predefined or A can be indicated / configured by the base station. Since the value range of BAI can be from 0 to F·X, that is, BAI can indicate F·X+1 values, determining the size of the BAI field based on F·X+1 can avoid some values from 0 to F·X not being indicated, thus improving the reliability of UE CSI reporting and consequently improving the reliability of the communication system.
[0358] Here, the relevant description of X is given above. The above method allows the UE to obtain the corresponding beam accuracy by the number (k) of time instances where the reported result is true / false, thereby saving the overhead of CSI reporting.
[0359] The following describes another method for determining CSI (e.g., BAI). Optionally, the accuracy corresponding to BAI is... Optionally, the accuracy corresponding to BAI can be the accuracy of inference / prediction. Optionally, the accuracy can be the accuracy reported by the first CSI. Optionally, the accuracy can be the accuracy of the inference / prediction results associated with the first CSI report. Optionally, the accuracy can be the accuracy of the inference / prediction associated with the configuration reported by the first CSI. Optionally, the accuracy can be the reported accuracy of the configuration associated by the first CSI. Optionally, the accuracy can be the accuracy of the inference / prediction (reported) associated with the configuration reported by the first CSI. Optionally, the accuracy can be the accuracy of the inference / prediction results (reported) associated with the configuration reported by the first CSI. Optionally, the value of BAI can be m. Optionally, the value m of BAI can refer to: there are m measurements associated with the third resource set whose comparison results are true. Optionally, the value m of BAI can refer to the number of measurements among one or more measurements associated with the third resource set whose comparison results are true. For example, one or more measurements associated with the third resource set can be M measurements associated with the third resource set. Optionally, M ≥ 1. Optionally, m measurements associated with the third resource set are derived from M measurements associated with the third resource set. Optionally, 0 ≤ m ≤ M.
[0360] Optionally, the value m of BAI can refer to the number of comparison results that are false for m measurements associated with the third resource set. Alternatively, the value m of BAI can refer to the number of measurements among one or more measurements associated with the third resource set whose corresponding comparison results are false. In this case, the accuracy corresponding to BAI is... or,
[0361] Optionally, the size of the BAI field (or the field corresponding to BAI) is Or, log2M. Here, This refers to the floor operation. Optionally, the size of the BAI field (or the field corresponding to BAI) is determined based on M+1. For example, the size of the BAI field (or the field corresponding to BAI) is equal to... Or, log2(M+1), or, or, Here, B can be an integer greater than or equal to 1. For example, B can be one of 1, 2, 3, 4, 5, 6, 7, or 8. Optionally, B can be predefined or indicated / configured by the base station. Since the value range of BAI can be from 0 to M, that is, BAI can indicate M+1 values, determining the size of the BAI field based on M+1 can avoid some values from 0 to M not being indicated, thus improving the reliability of UE CSI reporting and consequently improving the reliability of the communication system.
[0362] Optionally, M refers to the total number of one or more measurements associated with the third resource set being compared. Optionally, M refers to the total number of measurements being compared in a reporting instance (e.g., a reporting instance related to a second CSI reporting). Optionally, M refers to the total number of measurements used to determine the BAI in a reporting instance. Optionally, M (or the value of M) can be indicated by the base station, or predefined, or determined based on UE capabilities. For example, the value of M can be one of 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 32. For example, M can be indicated by at least one of RRC, MAC-CE, and DCI. For example, M can be indicated by the second CSI reporting configuration.
[0363] The above method enables the UE to obtain the value of M, so that the UE can obtain the corresponding beam accuracy by reporting the number (m) of measurements with true / false results, thereby saving the overhead of CSI reporting.
[0364] The following describes another method for determining CSI (e.g., BAI). Optionally, the value of BAI is determined by quantization of at least one of the following: Here, the descriptions of F, X, k, M, and m are as above. Here, the value of BAI is called p. Optionally, p is an integer. Optionally, p ≥ 0. The following uses... Let's take an example to describe it. For example... The description also applies to or, or, or, or,

Optionally, Optionally, Optionally, The value can be predefined or indicated by the base station. Optionally, The value can be one of 1, 0.75, 0.5, 0.25, or 0.125. Optionally, This indicates "out-of-range". Optionally, i = 0, 1, ..., M q -1. Optionally, M q =2 C Where C represents the number of bits in the CSI field corresponding to BAI. Optionally, the value p of BAI indicates the value of the CSI field corresponding to BAI. The value of δ p and δ p+1 Between.

Optionally, i = 1, ..., M q Optionally, M q =2 C Where C represents the number of bits in the CSI field corresponding to BAI.

[0369] Another method for determining CSI (e.g., BAI) is described below.
[0370] Optionally, BAI may include X bits. For example, BAI may include a bit sequence: b1, b2, ..., b X Optionally, b1 can be the least significant bit (LSB). X It can be the Most Significant Bit (LSB). Optionally, b xThis corresponds to the comparison result reported by the first CSI for the x-th time. Optionally, 1 ≤ x ≤ X. For example, b x The first value (e.g., 1) indicates that the comparison result of the xth first CSI report (out of X first CSI reports) is true. For example, b x The second value (e.g., 0) indicates that the comparison result of the xth first CSI report (out of X first CSI reports) is false. See above for the comparison method associated with the first CSI reports.
[0371] The above method enables the UE to indicate the comparison result of each of the X first CSI reports, so that the base station can perform model management accordingly, thereby improving the performance of the communication system.
[0372] Optionally, BAI may include F*X bits. For example, BAI may include a bit sequence: b1, b2, ..., b F*X Optionally, b1 can be the least significant bit (LSB). F*X It can be the Most Significant Bit (LSB). Optionally, b m This corresponds to a comparison result of a time instance associated with a first CSI report. Optionally, 1 ≤ m ≤ F*X. For example, b m The first value (e.g., 1) indicates that the comparison result of the corresponding time instance (in the X first CSI reports) is true. For example, b m The second value (e.g., 0) indicates that the comparison result of the corresponding time instance is false. Here, the correspondence between m and the time instance associated in the first CSI report can be determined in the following way.
[0373] ●Optionally, m = F*(x-1) + f. For example, the f-th time instance associated with the x-th first CSI report in X first CSI reports corresponds to b. m , where m=F*(x-1)+f.
[0374] ●Optional, b m Corresponding to the first CSI report of X The first CSI report related to the A time instance.
[0375] The above method enables the UE to indicate the comparison results of each time instance associated with each of the X first CSI reports, so that the base station can perform model management accordingly, thereby improving the performance of the communication system.
[0376] Optionally, the CSI report associated with / corresponding to the second CSI reporting configuration may include V BAIs. Optionally, V ≥ 1. Optionally, V ≤ F. Optionally, each of the V BAIs corresponds to / is associated with one time instance. For example, there is a one-to-one correspondence between the V BAIs and the V time instances. For example, the V time instances may come from F time instances. For example, the V time instances may be a subset of the F time instances. Optionally, one BAI corresponding to one time instance means that the BAI is determined based on the comparison of the time instance associated in the CSI report (e.g., the CSI report corresponding to the first CSI reporting configuration). For example, a BAI is associated with the f-th time instance among F time instances, and this BAI is determined based on the CSI associated with the f-th time instance in the CSI report.
[0377] Optionally, the V time instances can be predefined. For example, the V time instances can be the first time instance out of F time instances. For example, the V time instances can be the last time instance out of F time instances. For example, the V time instances can refer to F time instances.
[0378] Optionally, the V time instances can be indicated by the base station. For example, the second CSI reporting configuration includes a parameter that indicates the V time instances. For example, the V time instances are the first V time instances out of F time instances. Optionally, the value of V can be indicated by the base station. For example, the second CSI reporting configuration includes a parameter that indicates the value of V. For example, the V time instances are indicated by a bitmap. The bitmap includes F bits, where the f-th bit corresponds to the f-th time instance out of the F time instances. When a bit in the bitmap is a first value (e.g., 1), the corresponding time instance is indicated. When a bit in the bitmap is a second value (e.g., 0), the corresponding time instance is not indicated.
[0379] Optionally, the mapping order of the V CSI fields corresponding to the V BAIs can be determined based on the temporal order (e.g., the chronological order) of the V time instances corresponding to the V BAIs. Optionally, the mapping order of the V CSI fields can be the order of the V CSI fields in the UCI. Optionally, the mapping order of the V CSI fields can be the order of the V CSI fields in the CSI reporting. Optionally, the mapping order of the V CSI fields can be the order of the information bits corresponding to the V CSI fields in the information bits carried in the CSI reporting. For example, the V BAIs correspond to BAI#1, BAI#2, ..., BAI#V. In the CSI reporting, the V BAIs are arranged from BAI#1 to BAI#V. Optionally, BAI#1, BAI#2, ..., BAI#V correspond to time instances #1, #2, ..., #V among the V time instances. Optionally, time instance #v is the v-th time instance among the V time instances. Optionally, time instance #v is the v-th earliest time instance among the V time instances. Optionally, time instance #v is the v-th latest time instance among the V time instances. Optionally, v ≤ V. Optionally, v ≥ 1. The above method clarifies the order of the CSI fields corresponding to the V BAIs in CSI reporting, avoiding the UE from using an incorrect method to map the CSI fields corresponding to the V BAIs in CSI reporting, thus improving the reliability of the communication system.
[0380] The resource corresponding to the resource indicator is a resource in the first resource set, and the resource determined by measuring all resources in the third resource set is also a resource in the third resource set. To facilitate the comparison between the resource corresponding to the resource indicator and the resources in the third resource set (and to determine the comparison result), it is necessary to provide a mapping relationship between the resources in the first and third resource sets, and to clarify the comparison operation used to determine the CSI, in order to ensure the reliability of the communication system. The method for determining the resource associated with the resource indicator is described above. If the resource indicator corresponds to a resource in the second resource set, the description of the "first resource set" in the method for determining the resource associated with the resource indicator can be replaced with a description of the "second resource set".
[0381] The following discussion outlines the method for determining the X first CSI reports. This method enables the base station to correctly understand which first CSI reports are being monitored in the second CSI reports, allowing the base station to adjust its UE-side model based on the reported monitoring results, thereby improving the reliability of the communication system.
[0382] Optionally, the X first CSI reports can be X CSI reports that are no later than the second CSI report. Optionally, X first CSI reports that are no later than the second CSI report mean that the time domain unit in which the X first CSI reports are located is no later than the time domain unit in which the second CSI report is located. Optionally, the X first CSI reports can be X CSI reports that are earlier than the second CSI report. Optionally, X first CSI reports that are earlier than the second CSI report mean that the time domain unit in which the X first CSI reports are located is earlier than the time domain unit in which the second CSI report is located. Optionally, the X first CSI reports can be the X CSI reports closest to the second CSI report. Optionally, the X first CSI reports can be the X most recent CSI reports preceding the second CSI report. Optionally, the X first CSI reports can be the X most recent CSI reports that are no later than the second CSI report. Optionally, the X first CSI reports can be the X CSI reports that precede the second CSI report (the closest to the second CSI report, or the closest to the time domain unit where the second CSI report is located). Alternatively, the X first CSI reports can be the X CSI reports that are no later than the second CSI report (the closest to the second CSI report, or the closest to the time domain unit where the second CSI report is located). Alternatively, the X first CSI reports can be the X CSI reports that are closest to the time domain unit where the second CSI report is located.
[0383] Optionally, at least one time instance associated with each of the X first CSI reports is no later than the second CSI report. Optionally, all time instances associated with each of the X first CSI reports (e.g., F time instances) are no later than the second CSI report. Optionally, all time instances associated with the X first CSI reports (e.g., F*X time instances) are no later than the second CSI report. In this document, the term "no later than" may be used interchangeably with the terms "earlier than" or "before". Optionally, "no later than the second CSI report" can be: no later than the time domain unit associated with the second CSI report. Optionally, the time domain unit associated with the second CSI report can be the time domain unit where the second CSI report (is sent). Optionally, the time domain unit associated with the second CSI report can be the first time domain unit (or, the starting time domain unit) or the last time domain unit (or, the ending time domain unit) of the resource carrying the second CSI report. Optionally, the X first CSI reports are (all) associated time instances that are no later than the most recent X first CSI reports of the second CSI report. Optionally, the X first CSI reports are associated time instances that are no later than the most recent X first CSI reports of the second CSI report that are closest to the second CSI report (or, the time domain unit associated with the second CSI report).
[0384] Optionally, when the second CSI report is an aperiodic CSI report, the second CSI report can be triggered / scheduled / indicated by the DCI.

For example, the base station can indicate the number of time-domain units associated with / corresponding to the window length through at least one of RRC signaling, MAC-CE, and DCI. Optionally, the window length can be determined based on the CSI reporting period associated with the first CSI reporting configuration and / or the period associated with the third resource set. Optionally, when the first CSI reporting is periodic CSI reporting, and / or the resources included in the third resource set are SSB or semi-persistent / periodic CSI-RS, the window length is determined based on the CSI reporting period associated with the first CSI reporting configuration and / or the period associated with the third resource set. Optionally, the window length is determined based on the longer / shorter period of the CSI reporting period associated with the first CSI reporting configuration and the period associated with the third resource set. Optionally, the window length is determined based on the maximum / minimum value of the CSI reporting period associated with the first CSI reporting configuration and the period associated with the third resource set.

[0394] Optionally, the starting / ending time-domain resources of the window are determined based on the time-domain resources where the second CSI report is located and / or the indication from the base station. For example, the distance between the starting / ending time-domain resources of the window and the time-domain resources where the second CSI report is located is predefined or indicated by the base station. For example, the distance between the starting / ending time-domain resources of the window and the time-domain resources of the channel carrying the second CSI report (e.g., the first time-domain resource, or the last time-domain resource) is predefined or indicated by the base station. For example, the time-domain resource offset between the starting / ending time-domain resources of the window and the time-domain resources where the second CSI report is located is Y, where Y can be predefined or indicated by the base station. For example, the value of Y can be one of 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 32. For example, Y can be indicated by at least one of RRC, MAC-CE, and DCI. For example, when the time domain resource where the second CSI report is located is time slot n, the time domain resource where the start time domain resource / end time domain resource of this window is located is time slot nY or n+Y.
[0395] Optionally, the starting / ending time-domain resources of the window are determined based on the time-domain resources of the CSI reference resource corresponding to the second CSI report and / or the indication from the base station. For example, the distance between the starting / ending time-domain resources of the window and the time-domain resources of the CSI reference resource corresponding to the second CSI report is predefined or indicated by the base station. For example, the distance between the starting / ending time-domain resources of the window and the time-domain resources of the CSI reference resource corresponding to the second CSI report (e.g., the first time-domain resource, or the last time-domain resource) is predefined or indicated by the base station. For example, the time-domain resource offset between the starting / ending time-domain resources of the window and the time-domain resources of the CSI reference resource corresponding to the second CSI report is Z, where Z can be predefined or indicated by the base station. For example, the value of Z can be one of 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 32. For example, Z can be indicated by at least one of RRC, MAC-CE, and DCI. For example, when the time domain resource corresponding to the CSI reference resource of the second CSI report is time slot n, the time domain resource of the starting / ending time domain resource of the window associated with the second CSI report is time slot nZ or n+Z. Optionally, the starting / ending time domain resource of the window is determined based on the time domain resource of the second CSI report and / or the CSI reporting period associated with the first CSI report configuration and / or the period associated with the third resource set. The CSI reporting period associated with the first CSI report configuration and / or the period associated with the third resource set can be the maximum / minimum value of the CSI reporting period associated with the first CSI report configuration and the period associated with the third resource set. Optionally, the time slot number of the starting / ending time domain resource of the window is n*P, where P is determined based on the CSI reporting period associated with the first CSI report configuration and / or the period associated with the third resource set. For example, P is the number of time slots corresponding to the CSI reporting period associated with the first CSI report configuration. Here, n is an integer. The slot number associated with the start time domain resource / end time domain resource of the window is n*P, where n is the slot that minimizes the offset between the slot corresponding to n*P and the slot where the second CSI report is located.
[0396] Optionally, the N1 resources associated with one (or each) time instance in the first CSI report (e.g., resources corresponding to the N resource indicators) are mapped to resources in the third resource set. Optionally, the N1 resources associated with one (or each) time instance in one of the X CSI reports are mapped to resources in the third resource set. Optionally, the X CSI reports satisfy the following condition: at least one (or each) time instance associated with the first CSI report in the X CSI reports is mapped to resources in the third resource set. Optionally, the mapping of the N1 resources associated with one time instance in the first CSI report to resources in the third resource set refers to: at least one resource among the N1 resources associated with one time instance in the first CSI report (e.g., at least one resource among the N1 resource indicators) is mapped to resources in the third resource set. Optionally, the mapping between the N1 resources associated with a time instance of the first CSI report and the resources in the third resource set refers to the mapping between each resource in the N1 resources associated with a time instance of the first CSI report (e.g., each resource corresponding to the N1 resource indicators) and the resources in the third resource set. See other sections of this document for a description of the resource mapping method.
[0397] Optionally, if one (or each) of the X CSI reports is not mapped to a resource in the third resource set, then the second CSI report is not sent (or the second CSI report is discarded). Optionally, "the first CSI report is not mapped to a resource in the third resource set" means that at least one resource among the N1 resources associated with each time instance of the first CSI report (e.g., at least one resource among the resources corresponding to the N1 resource indicators) is not mapped to a resource in the third resource set. Optionally, "the first CSI report is not mapped to a resource in the third resource set" means that each resource among the N1 resources associated with each time instance of the first CSI report (e.g., each resource among the resources corresponding to the N1 resource indicators) is not mapped to a resource in the third resource set. This method allows the UE to avoid reporting when the predicted beam associated with the X CSI reports is not mapped to a resource in the resource set used for monitoring, since the comparison result is already known to the base station, thus saving UE energy consumption and improving the efficiency of the communication system.
[0398] The following discussion focuses on the method for determining the measurement of the third resource set. This method enables the UE to compare the measurement results of the first CSI report with those of a monitoring set that is closer in time domain to the time domain instance associated with that report, thereby improving the timeliness and accuracy of performance monitoring.
[0399] Optionally, the measurement of the third resource set can refer to: the measurement result of the third resource set. Optionally, the measurement of the third resource set can refer to: the measurement of the transmission opportunity of resources in the third resource set, and / or, the measurement of resources in the third resource set, and / or, the measurement of all resources in the third resource set. Optionally, the resource associated with the resource indicator included in the CSI associated with each time instance in each of the X first CSI reports can be compared with the resources determined based on the measurement of the third resource set. Here, the measurement opportunity (or transmission opportunity) used for comparison with the corresponding time instance can be referred to as the transmission opportunity associated with the time instance. Optionally, the transmission opportunity associated with the f-th time instance associated with the x-th CSI report in the X first CSI reports can be at least one of the following:
[0400] ● A transmission opportunity no later than (or earlier than) the resource in the third resource set reported by the second CSI. For example, the most recent transmission opportunity of a resource in the third resource set reported by the second CSI. For example, the x-th most recent transmission opportunity of a resource in the third resource set reported by the second CSI;
[0401] ● A transmission opportunity no later than (or earlier than) the resource in the third resource set corresponding to the CSI reference resource reported by the second CSI; for example, the most recent transmission opportunity of the resource in the third resource set corresponding to the CSI reference resource reported by the second CSI. For example, the x-th most recent transmission opportunity of the resource in the third resource set corresponding to the CSI reference resource reported by the second CSI;
[0402] ● The nearest transmission opportunity for a resource in the third resource set. For example, the transmission opportunity for a resource in the third resource set closest to the f-th time instance associated with the x-th CSI report. Optionally, the distance between the f-th time instance associated with the x-th CSI report and the transmission opportunity for the resource can be: the distance between the time domain unit associated with the f-th time instance and the time domain resource where the transmission opportunity for the resource is located. Here, the distance can be an offset of the time domain resource. Optionally, if two transmission opportunities are equidistant from the f-th time instance, the later transmission opportunity is used for comparison. Optionally, if two transmission opportunities are equidistant from the f-th time instance, the earlier transmission opportunity is used for comparison. Here, the unit of time domain resource can be a time slot or a symbol.
[0403] Optionally, the measurement of the third resource set can refer to: a measurement of the third resource set within a window associated with a time instance. Optionally, the measurement of the third resource set can refer to: a measurement of the transmission opportunity of resources in the third resource set, and / or, a measurement of resources in the third resource set. Optionally, each time instance associated with each CSI report in X first CSI reports can be based on a relevant comparison of the measurement of the third resource set within the window. The temporal position of a window associated with a time instance can be determined by the length of the window and the start point (e.g., the starting temporal resource) and / or the end point (e.g., the ending temporal resource). The method for determining a window associated with a time instance is described below.
[0404] Optionally, the length of the window associated with the f-th time instance among the x-th (1≤x≤X) CSI reports in the X first CSI reports is indicated by the base station. For example, the base station indicates the number of time-domain units associated with / corresponding to the length of the window through at least one of RRC signaling, MAC-CE, and DCI. Optionally, the length of the window associated with the x-th (1≤x≤X) CSI report in the X first CSI reports is determined based on the CSI reporting period associated with the first CSI reporting configuration and / or the period associated with the third resource set and / or F_offset. See above for a description of F_offset. Optionally, when the first CSI report is a periodic CSI report, and / or, the resources included in the third resource set are SSBs or semi-persistent / periodic CSI-RS, and / or, F>1, the length of the window associated with the x-th (1≤x≤X) CSI report among the X first CSI reports is determined based on the CSI reporting period associated with the first CSI report configuration and / or the period associated with the third resource set and / or F_offset. Optionally, the length of the window associated with the f-th time instance among the x-th (1≤x≤X) CSI report among the X first CSI reports is determined based on the longer / shorter length of the CSI reporting period associated with the first CSI report configuration and / or the period associated with the third resource set and / or F_offset. Optionally, the length of the window associated with the x-th (1≤x≤X) CSI report among the X first CSI reports is determined based on the maximum / minimum value among the CSI reporting period associated with the first CSI reporting configuration and / or the period associated with the third resource set and / or F_offset. For example, the length of the window associated with the x-th (1≤x≤X) CSI report among the X first CSI reports is a*P. Optionally, P can correspond to the period associated with the third resource set, or the CSI reporting period associated with the first CSI reporting configuration, or F_offset, or the maximum / minimum value among the period associated with the third resource set and / or the CSI reporting period associated with the first CSI reporting configuration and / or F_offset. Here, a can be a scaling factor. The value of a can be one of 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 32. Optionally, a can be predefined. Optionally, a can be indicated by the base station. For example, 'a' can be indicated by at least one of RRC signaling, MAC-CE, or DCI. Here, the relevant descriptions of the CSI reporting cycle associated with the CSI reporting configuration and the cycle associated with the third resource set are provided above.
[0405] Optionally, the start time domain resource / end time domain resource of the window associated with the x-th (1≤x≤X)-th CSI report in the X first CSI reports is determined based on at least one of the following:

[0410] ●The cycle of the third resource set association.
[0411] Optionally, the start / end time domain resources of the window associated with the x-th (1≤x≤X)th CSI report in the X first CSI reports are determined based on the indication of the f-th time instance and / or the base station. For example, the distance between the start / end time domain resources of the window associated with the f-th time instance and the f-th time instance (or, the time domain unit associated with the f-th time instance) is predefined or indicated by the base station. For example, the time domain unit offset between the start / end time domain resources of the window associated with the x-th CSI report and the time domain unit associated with the f-th time instance is Y, where Y can be predefined or indicated by the base station. For example, the value of Y can be one of 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 32. For example, Y can be indicated by at least one of RRC, MAC-CE, and DCI. For example, the time domain resource where the start time domain resource / end time domain resource of the window associated with the f-th time instance is located is time slot nY or n+Y, where n refers to the number of the time domain unit associated with the f-th time instance.
[0412] Optionally, the starting time domain resource / ending time domain resource of the window associated with the f-th time instance of the x-th (1≤x≤X) CSI report in the X first CSI reports is determined based on the f-th time instance (or, the time domain unit associated with the f-th time instance) and / or the CSI reporting period associated with the first CSI report configuration and / or the period associated with the third resource set. The CSI reporting period associated with the first CSI report configuration and / or the period associated with the third resource set can be the maximum / minimum value of the CSI reporting period associated with the first CSI report configuration and the period associated with the third resource set. Optionally, the time slot where the starting time domain resource / ending time domain resource of the window associated with the x-th CSI report is located is numbered n*P, where P is determined based on the CSI reporting period associated with the first CSI report configuration and / or the period associated with the third resource set. For example, P is the number of time slots corresponding to the CSI reporting period associated with the first CSI report configuration. Here, n is an integer. The slot number associated with the start time domain resource / end time domain resource of the window associated with the f-th time instance is n*P, where n is the n that minimizes the offset between the slot corresponding to n*P and the slot where the f-th time instance is located. Optionally, if there is more than one n that minimizes the offset between the slot corresponding to n*P and the slot where the f-th time instance is located, the window corresponding to the smaller / larger n value is used for comparison.
[0413] The following discussion outlines the method for determining the M measurements associated with the third resource set. This method enables the base station to correctly understand which measurements associated with the third resource set correspond to the CSI reported in the second CSI report.

Optionally, the above method can be applied to the case of semi-continuous CSI reporting and / or periodic CSI reporting corresponding to a first CSI reporting configuration (e.g., a first CSI reporting configuration associated with a second CSI reporting configuration).
