Description

A communication method, apparatus and storage medium

[0001] This application claims priority to Chinese Patent Application No. 202510392134.0, filed on March 28, 2025, entitled "A Communication Method, Apparatus and Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of wireless communication technology, and in particular to a communication method, apparatus and storage medium. Background Technology

[0003] Beam management is a systematic technology in 5G and 6G wireless communication systems that optimizes the communication link quality between user equipment (UE) and next-generation node base stations (gNB) by dynamically adjusting beam direction, resource allocation, and link strategies. With the increase in communication frequency bands and antenna size, the coverage area of ​​a beam decreases, and the number of beams that need to be scanned increases significantly, consuming more data transmission resources and reducing the resources available for transmitting service data, thus affecting the communication link quality between the UE and gNB. Currently, to reduce beam scanning overhead, gNBs can utilize artificial intelligence (AI) models on the UE side for beam management. For example, the UE can input signal quality measurement results from a small number of beams into the AI ​​model to predict the signal quality of a larger number of beams.

[0004] However, AI models are trained based on statistical data in specific scenarios. When the scenario changes, the performance of the AI ​​model will decrease. At this time, the terminal device cannot make effective beam signal quality prediction with the help of the AI ​​model and a small number of beam signal quality measurement results, which may lead to inaccurate beam signal quality prediction. Therefore, monitoring the prediction accuracy of the AI ​​model in predicting the signal quality of the reference signal has become an urgent problem to be solved. Summary of the Invention

[0005] This application provides a communication method, apparatus, and storage medium. By determining the relationship between the signal quality measurement result and the signal quality prediction result during the monitoring process of the signal quality prediction result of a reference signal, the terminal device can effectively compare the signal quality prediction result with the signal quality measurement result corresponding to the signal quality prediction result, thereby obtaining the accuracy of the signal quality prediction result of the reference signal.

[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0007] In a first aspect, embodiments of this application provide a communication method that can be applied to a terminal device. As an example, the terminal device may be a communication module, a circuit or chip responsible for communication functions, a chip system, or other components or parts. This communication module, circuit or chip responsible for communication functions, chip system, or other components or parts can be applied in the terminal device. The method includes:

[0008] Receive at least one first reference signal set from a network device, wherein the first reference signal set in the at least one first reference signal set is used to determine a first result, the first result being predicted based on a signal quality measurement result corresponding to a reference signal in the first reference signal set, and the first result being used to indicate a signal quality prediction result of a reference signal in a second reference signal set corresponding to the first reference signal set;

[0009] Receive M sets of third reference signals from network devices. The M sets of third reference signals correspond to different transmission timings. The third reference signal set among the M sets of third reference signals is used to determine the second result. The second result is used to indicate the signal quality measurement result of the reference signal in the third set of third reference signals. The second result is used to monitor the prediction accuracy of the first result.

[0010] Send first information to the network device. The first information includes monitoring results of K first results. The first first result among the K first results is determined based on the time domain position corresponding to the first result among the K first results and the time domain position of the first third reference signal set among the M third reference signal sets. The Kth first result among the K first results is determined based on the time domain position corresponding to the first result and the channel state information reference resource used to carry the first information. The monitoring result of the kth first result among the K first results is determined based on the kth first result and the second result corresponding to the kth first result among the M second results. The second result corresponding to the kth first result is determined based on the time domain position corresponding to the kth first result and the time domain position of the third reference signal set among the M third reference signal sets. k is less than or equal to K, and both k and K are positive integers.

[0011] Based on the communication method provided in the embodiments of this application, the terminal device can associate the signal quality measurement result with the signal quality prediction result during the monitoring process of the signal quality prediction result of the reference signal, so that the signal quality prediction result and the corresponding signal quality measurement result can be effectively compared, thereby obtaining the accuracy of the signal quality prediction result of the reference signal.

[0012] In one possible implementation of the first aspect, the time-domain location corresponding to the first result includes:

[0013] The transmission start time of the channel used to carry the first report, the first report including the first result;

[0014] Alternatively, it can be used as a reference resource for carrying the channel state information of the first report;

[0015] Alternatively, the start time of the first reference signal set closest to the channel state information reference resource used to carry the first report, and the start time of the first reference signal set is not later than the channel state information reference resource used to carry the first report.

[0016] Therefore, the terminal device can clearly know the time-domain location of the signal quality prediction result of the reference signal in the second reference signal set.

[0017] In one possible implementation of the first aspect, the time-domain location of the third reference signal set among the M third reference signal sets includes:

[0018] The start time of the third reference signal set;

[0019] Alternatively, the moment when the second result is obtained can be determined using a third set of reference signals.

[0020] Therefore, the terminal device can clearly know the time domain location of the third reference signal set.

[0021] In one possible implementation of the first aspect, the first result, the time-domain position corresponding to the first result, and the time-domain position of the first third reference signal set satisfy the following relationship:

[0022] The first first result is the first result included in the first report whose time-domain position is closest to the time-domain position of the first third reference signal set among the K first results, and the time-domain position corresponding to the first result is no earlier than the time-domain position of the first third reference signal set.

[0023] Therefore, the terminal device can accurately know the first of the K first results, which is the starting point of the signal quality prediction result monitoring process of the reference signal (in this embodiment, the signal quality prediction result monitoring process of the reference signal can also be called the monitoring window).

[0024] In one possible implementation of the first aspect, the Kth first result, the time-domain location corresponding to the first result, and the channel state information reference resource used to carry the first information satisfy the following relationship:

[0025] The Kth first result is the first result included in the first report whose time-domain location is closest to the channel state information reference resource used to carry the first information, and the transmission start time of the channel used to carry the first report is not later than the channel state information reference resource used to carry the first information.

[0026] Therefore, the terminal device can accurately obtain the Kth first result out of the K first results, which is the endpoint of the signal quality prediction result monitoring process (monitoring window) of the reference signal.

[0027] In one possible implementation of the first aspect, the second result corresponding to the kth first result is the signal quality measurement result of the reference signal in the third set of M third reference signals whose time domain position is closest to the time domain position corresponding to the kth first result.

[0028] Alternatively, the second result corresponding to the kth first result is the signal quality measurement result of the reference signal in the third reference signal set whose time domain position is closest to the time domain position corresponding to the kth first result among the M third reference signal sets, and the time interval between the time domain position of the third reference signal set among the M third reference signal sets and the time domain position corresponding to the kth first result is less than the first time threshold.

[0029] Alternatively, the second result corresponding to the kth first result is the signal quality measurement result of the reference signal in the third reference signal set whose time domain position is closest to the time domain position corresponding to the kth first result among the M third reference signal sets; the time interval between the time domain position of the third reference signal set among the M third reference signal sets and the time domain position corresponding to the kth first result is less than the first time threshold; and the time domain position of the third reference signal set among the M third reference signal sets is no later than the time domain position corresponding to the (k+1)th first result.

[0030] Therefore, the second result corresponding to the kth first result among the K first results can be accurately obtained. Furthermore, by providing multiple methods for determining the second result corresponding to the kth first result among the K first results, the flexibility of the terminal device in determining the second result corresponding to the kth first result among the K first results is improved.

[0031] In one possible implementation of the first aspect, the monitoring results of the K first results include beam prediction parameters, which are used to indicate the prediction accuracy of the first results.

[0032] Therefore, the terminal device can determine the accuracy of the first result based on the magnitude of the beam prediction parameters.

[0033] In one possible implementation of the first aspect, the method further includes, before sending the first information to the network device:

[0034] If there exists a second result corresponding to the first result among the K first results, increment the value of the first counter by one to obtain the first counting parameter;

[0035] If the first result and the second result corresponding to the first result satisfy the first condition, the value of the second counter is incremented by one to obtain the second counting parameter. The first condition includes: at least one of the reference signals in the third reference signal set that are among the top X largest reference signals in the signal quality measurement results exists in the fourth reference signal set. The fourth reference signal set includes the reference signals in the third reference signal set that are among the top P largest reference signals in the signal quality prediction results.

[0036] When the value of the first counting parameter is accumulated to L or when K first results have been traversed, the beam prediction parameters are determined based on the second counting parameter and the first counting parameter.

[0037] Therefore, the terminal device can accurately obtain the beam prediction parameters based on the conditions described above for obtaining the beam prediction parameters, thereby accurately knowing the prediction accuracy of the first result.

[0038] In one possible implementation of the first aspect, when the beam prediction parameter is not the ratio of the second counting parameter to the first counting parameter, the number of bits for both the first and second counting parameters can be [missing information]. bits, This indicates rounding up, where L is a positive integer.

[0039] Secondly, embodiments of this application provide a communication method that can be applied to network devices. As an example, the network device may be a communication module, a circuit or chip responsible for communication functions, a chip system, or other components or parts.

[0040] The network device sends at least one first reference signal set to the terminal device. The first reference signal set in the at least one first reference signal set is used to determine a first result. The first result is predicted based on the signal quality measurement result corresponding to the reference signal in the first reference signal set. The first result is used to indicate the signal quality prediction result of the reference signal in the second reference signal set corresponding to the first reference signal set.

[0041] M sets of third reference signals are sent to the terminal device. Different sets of the M sets of third reference signals correspond to different transmission timings. The sets of third reference signals in the M sets of third reference signals are used to determine the second result. The second result is used to indicate the signal quality measurement result of the reference signals in the sets of third reference signals. The second result is used to monitor the prediction accuracy of the first result.

[0042] The system receives first information from a terminal device. The first information includes monitoring results of K first results. The first first result among the K first results is determined based on the time-domain position corresponding to the first result among the K first results and the time-domain position of the first third reference signal set among the M third reference signal sets. The Kth first result among the K first results is determined based on the time-domain position corresponding to the first result and the channel state information reference resource used to carry the first information. The monitoring result of the kth first result among the K first results is determined based on the kth first result and the second result corresponding to the kth first result among the M second results. The second result corresponding to the kth first result is determined based on the time-domain position corresponding to the kth first result and the time-domain position of the third reference signal set among the M third reference signal sets. k is less than or equal to K, and both k and K are positive integers.

[0043] Based on the communication method provided in the embodiments of this application, the network device can, with the help of the terminal device, determine the relationship between the signal quality measurement result and the signal quality prediction result during the signal quality prediction result monitoring process of the reference signal, effectively compare the signal quality prediction result with the signal quality measurement result corresponding to the signal quality prediction result, thereby realizing the accuracy of the signal quality prediction result of the reference signal.

[0044] Thirdly, embodiments of this application provide a communication method that can be applied to a terminal device. As an example, the terminal device may be a communication module, a circuit or chip responsible for communication functions, a chip system, or other components or parts. This communication module, circuit or chip responsible for communication functions, chip system, or other components or parts can be applied in the terminal device. The method includes:

[0045] M sets of third reference signals are received from a network device. Different sets of the M sets of third reference signals correspond to different transmission timings. The sets of third reference signals in the M sets of third reference signals are used to determine a second result. The second result is used to indicate the signal quality measurement result of the reference signal in the third set of third reference signals. The second result is used to monitor the prediction accuracy of the fourth result in the third result. The third result is predicted based on the signal quality measurement result corresponding to the reference signal in the first set of reference signals. The third result is used to indicate the signal quality prediction result of the reference signal in the second set of reference signals corresponding to the first set of reference signals. The third result includes at least one fourth result. Different fourth results in the at least one fourth result correspond to different time domain positions.

[0046] The second information is sent to the network device. The second information includes the monitoring results of K fourth results. The first fourth result among the K fourth results is determined based on the time domain position corresponding to the fourth result among the K fourth results and the time domain position of the first third reference signal set among the M third reference signal sets. The Kth fourth result among the K fourth results is determined based on the transmission start time of the channel used to carry the second report and the channel state information reference resource used to carry the second information. The monitoring result of the kth fourth result among the K fourth results is determined based on the kth fourth result and the second result corresponding to the kth fourth result among the M second results. The second result corresponding to the kth fourth result is determined based on the time domain position corresponding to the kth fourth result and the time domain position of the third reference signal set among the M third reference signal sets. k is less than or equal to K, and both k and K are positive integers.

[0047] Based on the communication method provided in the embodiments of this application, the terminal device can associate the signal quality measurement result with the signal quality prediction result during the monitoring process of the signal quality prediction result of the reference signal, so that the signal quality prediction result and the corresponding signal quality measurement result can be effectively compared, thereby obtaining the accuracy of the signal quality prediction result of the reference signal.

[0048] In one possible implementation of the third aspect, the time-domain location corresponding to the fourth result includes:

[0049] The fourth result is a symbol corresponding to a time-domain location.

[0050] Therefore, the terminal device can clearly know the time-domain location of the signal quality prediction result of the reference signal in the second reference signal set.

[0051] In one possible implementation of the third aspect, the time-domain location of the third reference signal set among the M third reference signal sets includes:

[0052] The start time of the third reference signal set;

[0053] Alternatively, the moment when the second result is obtained through a third set of reference signals.

[0054] Therefore, the terminal device can clearly know the time domain location of the third reference signal set.

[0055] In one possible implementation of the third aspect, the first fourth result, the time-domain location corresponding to the fourth result, and the time-domain location of the first third reference signal set satisfy the following relationship:

[0056] The first fourth result is the first fourth result included in the second report among the K fourth results whose time-domain location is closest to the time-domain location of the first third reference signal set, and the time-domain location corresponding to the fourth result is no earlier than the time-domain location of the first third reference signal set. The second report includes at least one fourth result.

[0057] Therefore, the terminal device can accurately obtain the first of the K fourth results, which is the starting point of the signal quality prediction result monitoring process of the reference signal (in this embodiment, the signal quality prediction result monitoring process of the reference signal can also be called the monitoring window).

[0058] In one possible implementation of the third aspect, the following relationship is satisfied between the Kth fourth result, the transmission start time of the channel used to carry the second report, and the time-domain location of the channel state information reference resource used to carry the second information:

[0059] The Kth fourth result is the last fourth result included in the second report among the K fourth results whose time-domain location is closest to the channel state information reference resource used to carry the second information, and the transmission start time of the channel used to carry the second report is not later than the channel state information reference resource used to carry the second information. The second report includes at least one fourth result.

[0060] Therefore, the terminal device can accurately obtain the Kth fourth result out of the K fourth results, which is the endpoint of the signal quality prediction result monitoring process (monitoring window) of the reference signal.

[0061] In one possible implementation of the third aspect, the second result corresponding to the kth fourth result is the signal quality measurement result of the reference signal in the set of M third reference signals whose time domain position is closest to the time domain position corresponding to the kth fourth result.

[0062] Alternatively, the second result corresponding to the kth fourth result is the signal quality measurement result of the reference signal in the third reference signal set whose time domain position is closest to the time domain position corresponding to the kth fourth result among the M third reference signal sets, and the time interval between the time domain position of the third reference signal set among the M third reference signal sets and the time domain position corresponding to the kth fourth result is less than the second time threshold.

[0063] Alternatively, the second result corresponding to the kth fourth result is the signal quality measurement result of the reference signal in the third reference signal set whose time domain position is closest to the time domain position corresponding to the kth fourth result among the M third reference signal sets. The time interval between the time domain position of the third reference signal set among the M third reference signal sets and the time domain position corresponding to the kth fourth result is less than the second time threshold, and the time when the second result is determined by the third reference signal set is no later than the channel state information reference resource of the next second report after the second report.

[0064] Therefore, the second result corresponding to the kth fourth result among the K fourth results can be accurately obtained. Furthermore, by providing multiple methods for determining the second result corresponding to the kth fourth result among the K fourth results, the flexibility of the terminal device in determining the second result corresponding to the kth fourth result among the K fourth results is improved.

[0065] In one possible implementation of the third aspect, the monitoring results of the K fourth results include beam prediction parameters, which are used to indicate the prediction accuracy of the fourth results.

[0066] Therefore, the terminal device can determine the accuracy of the fourth result based on the magnitude of the beam prediction parameters.

[0067] In one possible implementation of the third aspect, the method further includes, before sending the second information to the network device:

[0068] If there exists a second result corresponding to the fourth result among the K fourth results, increment the value of the first counter by one to obtain the first counting parameter;

[0069] If the fourth result and the second result corresponding to the fourth result satisfy the first condition, the value of the second counter is incremented by one to obtain the second counting parameter. The first condition includes: at least one of the reference signals in the third reference signal set that are among the X largest reference signals in the signal quality measurement results exists in the fourth reference signal set. The fourth reference signal set includes the reference signals in the third reference signal set that are among the P largest reference signals in the signal quality prediction results.

[0070] When the value of the first counting parameter is accumulated to L or when K fourth results have been traversed, the beam prediction parameter is determined based on the ratio of the second counting parameter to the first counting parameter.

[0071] Therefore, the terminal device can accurately obtain the beam prediction parameters based on the conditions used to obtain the beam prediction parameters, thereby accurately knowing the prediction accuracy of the fourth result.

[0072] In one possible implementation of the third aspect, when the beam prediction parameter is not the ratio of the second counting parameter to the first counting parameter, the number of bits for both the first and second counting parameters can be [missing information]. bits, This indicates rounding up, where L is a positive integer.

[0073] Fourthly, embodiments of this application provide a communication method that can be applied to network devices. As an example, the network device may be a communication module, a circuit or chip responsible for communication functions, a chip system, or other components or parts. This communication module, circuit or chip responsible for communication functions, chip system, or other components or parts can be applied in the network device. The method includes:

[0074] M sets of third reference signals are sent to the terminal device. Different sets of the M sets of third reference signals correspond to different transmission timings. The sets of third reference signals in the M sets of third reference signals are used to determine a second result. The second result is used to indicate the signal quality measurement result of the reference signal in the set of third reference signals. The second result is used to monitor the prediction accuracy of the fourth result in the third result. The third result is predicted based on the signal quality measurement result corresponding to the reference signal in the first set of reference signals.

[0111] This application provides a communication method that can be applied to a communication system, including but not limited to: wireless communication systems, such as narrowband Internet of Things (NB-IoT), Global System for Mobile Communications (GSM), enhanced data rate for GSM evolution (EDGE), wideband code division multiple access (WCDMA), code division multiple access 2000 (CDMA2000), time division-synchronization code division multiple access (TD-SCDMA), long term evolution (LTE) systems, 5G systems, 6G systems, and future wireless communication systems.

[0112] To facilitate understanding of the embodiments of this application, the communication system applicable to the embodiments of this application will be described first below.

[0113] Please refer to Figure 1, which is a schematic diagram of the architecture of a communication system provided in an embodiment of this application. As shown in Figure 1, the communication system provided in this embodiment of the application may include: a terminal device 10 and a network device 20, and the terminal device 10 and the network device 20 can communicate.

[0114] The terminal device 10 can be a wireless terminal or a wired terminal. A wireless terminal can be a device that provides voice and / or other service data connectivity to a user, such as a handheld device with wireless connectivity, or other processing devices connected to a wireless modem. The wireless terminal can communicate with one or more core networks via a radio access network (RAN). The wireless terminal can be a mobile terminal, such as a mobile phone (or "cellular" phone), or a computer with a mobile terminal, for example, a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device. These devices exchange voice and / or data with the radio access network.

[0115] Examples of such devices include Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), drones, wearable devices, and terminals in the Internet of Vehicles (IoV). Wireless terminals can also be referred to as systems, subscriber units, subscriber stations, mobile stations, mobile devices, remote stations, remote terminals, access terminals, user terminals, user agents, user devices or user equipment, UEs, terminal units, terminal stations, remote stations, mobile devices, terminals, wireless communication equipment, terminal agents, or terminal devices, etc., without limitation here.

[0116] Access terminals can be cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices or other processing devices connected to a wireless modem, in-vehicle devices, wearable devices, terminal devices in 5G networks or future 6G networks, or terminal devices in future evolved public land mobile networks (PLMNs), etc.

[0117] As an example, terminal device 10 may be a communication module, a circuit or chip responsible for communication functions, a chip system, or other components or parts. This communication module, circuit or chip responsible for communication functions, chip system, or other components or parts may be used in the terminal device.

[0118] In addition, the terminal device 10 may use a mobile operating system such as Android, Linux, Windows, or iOS, and this application embodiment does not limit this.

[0119] Network device 20 can be a base station, an access point, an access network device, or a device in the access network that communicates with a wireless terminal via one or more sectors on the air interface. Network device 20 can be used to convert received air frames to and from Internet Protocol (IP) packets, acting as a router between the wireless terminal and the rest of the access network, which may include an IP network. Network device 20 can also coordinate the attribute management of the air interface.

[0120] For example, network device 20 can be a base station (BTS) in satellite, drone, Global System for Mobile Communication (GSM) or Code Division Multiple Access (CDMA), or a base station (NodeB, NB) in Wideband Code Division Multiple Access (WCDMA), or an evolved Node B (eNB or eNodeB) in LTE, or a radio controller in a cloud radio access network (CRAN) scenario, or a terminal, relay station or access point that performs base station functions in wearable devices or vehicle-mounted devices, vehicular to everything (V2X), device-to-device (D2D) communication, and machine-to-machine (M2M) communication, or a base station in a 5G network, such as a gNB, or a base station in a future 6G network, or a network device in a future evolved public land mobile network (PLMN) network, and is not limited here.

[0121] Furthermore, as an example, network device 20 may be a communication module, a circuit or chip responsible for communication functions, a chip system, or other components or parts. This communication module, circuit or chip responsible for communication functions, chip system, or other components or parts may be used in a network device.

[0122] The terminal device 10 in this embodiment deploys an AI model, which is trained based on a reference signal (also known as a beam) and the measurement results of the reference signal in a specific scenario. The AI ​​model can be used for beam management. Specifically, the AI ​​model can infer the prediction results of a larger number of beams based on the measurement results of a small number of beams. For example, the AI ​​model can generate beam prediction results based on local reference signal measurement data or historical reference signal measurement data.

[0123] In actual beam management, when the performance of the AI ​​model deployed on the terminal device degrades, the terminal device may be unable to make effective beam signal quality predictions using the AI ​​model and a small number of beam signal quality measurement results, making it difficult to know the accuracy of the beam prediction performed by the terminal device.

[0124] To at least address the aforementioned problems, embodiments of this application provide a communication method.

[0125] In this communication method, the network device can send at least one first reference signal set to the terminal device, and the terminal device receives at least one first reference signal set. The terminal device can measure the signal quality of the reference signal in each of the at least one first reference signal set, and predict the signal quality of the reference signal in the second reference signal set based on the signal quality measurement results, thereby obtaining a signal quality prediction result (also referred to as a first result).

[0126] The network device can also send M sets of third reference signals to the terminal device. Different sets of the M third reference signals correspond to different transmission timings. The terminal device receives the M sets of third reference signals. The terminal device can measure the signal quality of the reference signal in each of the M sets of third reference signals to obtain a signal quality measurement result (also called a second result). The terminal device can use the second result to monitor the prediction accuracy of the first result, and upon obtaining the monitoring result of the accuracy of the first result, it sends first information to the network device.

[0127] By establishing the relationship between signal quality measurement results and signal quality prediction results during the signal quality prediction monitoring process, the terminal device can effectively compare the signal quality prediction results with the corresponding signal quality measurement results, thereby determining the accuracy of the signal quality prediction results for the reference signal.

[0128] The following section will describe the communication methods provided in the embodiments of this application in conjunction with different scenarios and accompanying drawings.

[0129] Scene 1:

[0130] The signal quality measurement results of reference signals in a first set of reference signals can be used to predict the signal quality of reference signals in a second set of reference signals, thus obtaining the signal quality prediction results of reference signals in the second set of reference signals, and each signal quality prediction result corresponds to a channel state information report.

[0131] Please refer to Figure 2, which is a signaling interaction diagram of a communication method provided in an embodiment of this application. This communication method can be applied to the communication system shown in Figure 1. As shown in Figure 2, the communication method includes:

[0132] S201. The network device sends at least one first reference signal set to the terminal device.

[0133] Correspondingly, the terminal device receives at least one first reference signal set from the network device.

[0134] The terminal device can be the terminal device 10 shown in Figure 1 above, and the network device can be the network device 20 shown in Figure 1 above.

[0135] Different sets of first reference signals in at least one set correspond to different transmission timings.

[0136] The first set of reference signals includes one or more reference signals, and the specific number of reference signals included in the first set of reference signals is not limited.

[0137] In this embodiment, each reference signal corresponds to one beam.

[0138] In some examples, reference signals in the first set of reference signals can be used to measure the signal quality of the reference signals.

[0139] For example, reference signals in the first set of reference signals can be used to measure the reference signal received power (RSRP) or the signal to interference plus noise ratio (SINR).

[0140] The reference signals in the first set of reference signals mentioned above are used to measure indicators only. In actual implementation, they may also be used to measure other indicators related to channel quality, which will not be elaborated here.

[0141] In other examples, the signal quality measurements of the reference signals in the first set of reference signals can be used to predict the probability that each reference signal in a second set of reference signals is the best reference signal.

[0142] The best reference signal refers to the reference signal with the highest (or best) signal quality in a set of reference signals.

[0143] The type of reference signal in the first set of reference signals is not limited. For example, the reference signals in the first set of reference signals can be a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS).

[0144] In this embodiment, at least one set of first reference signals in a first set of reference signals can be used to determine a first result, which is predicted based on signal quality measurement results corresponding to reference signals in the first set of reference signals.

[0145] For example, please refer to Figure 3, which is a schematic diagram of a first result provided by an embodiment of this application. As shown in Figure 1, based on the signal quality measurement results corresponding to the reference signals in the first reference signal set, the signal quality of multiple reference signals whose time domain positions are after the first reference signal set can be predicted to obtain the first result.

[0146] As one implementation method, the terminal device can use an AI model to predict the signal quality of multiple reference signals located after the first reference signal set in the time domain based on the signal quality measurement results of the reference signals in the first reference signal set, and obtain the signal quality prediction results of each of the multiple reference signals, which is the first result.

[0147] The first result can be used to indicate the signal quality prediction result of the reference signal in the second reference signal set corresponding to the first reference signal set. In some examples, the first result can be the RSRP or SINR of the reference signal in the second reference signal set corresponding to the first reference signal set.

[0148] The second set of reference signals includes the aforementioned multiple reference signals.

[0149] In one implementation, the number of reference signals in the second set of reference signals can be greater than the number of reference signals in the first set of reference signals.

[0150] In another implementation, the number of reference signals in the second set of reference signals can be less than the number of reference signals in the first set of reference signals. In this case, the density of reference signals in the second set of reference signals can be greater than the density of reference signals in the first set of reference signals.

[0151] Furthermore, in some possible implementations, the type of the reference signals in the second set of reference signals can be the same as the type of the reference signals in the first set of reference signals.

[0152] For example, the reference signals in the first set of reference signals can be of type CSI-RS, and the reference signals in the second set of reference signals can also be of type CSI-RS; or, the reference signals in the first set of reference signals can be of type SSB, and the reference signals in the second set of reference signals can also be of type SSB. In this case, the first set of reference signals can be a subset of the second set of reference signals.

[0153] In some other possible implementations, the types of reference signals in the second set of reference signals may be different from the types of reference signals in the first set of reference signals.

[0154] For example, the reference signal type in the first reference signal set can be SSB, and the reference signal type in the second reference signal set can be CSI-RS; or, the reference signal type in the first reference signal set can be CSI-RS, and the reference signal type in the second reference signal set can be SSB. In this way, the first reference signal set and the second reference signal set are different sets.

[0155] In one implementation, the reference signals in the second set of reference signals may be reference signals for the downlink.

[0156] The reference signals in the first set of reference signals are carried in a downlink channel. This downlink channel can be a physical broadcast channel (PBCH), a physical downlink control channel (PDCCH), or a physical downlink shared channel (PDSCH).

[0157] In some implementations, the reference signals in the first set of reference signals can be transmitted via radio resource control (RRC) signaling.

[0158] In other implementations, the reference signals in the first set of reference signals can be transmitted via downlink control information (DCI).

[0159] In some other implementations, the reference signals in the first set of reference signals can be transmitted via a MAC control element (MAC CE).

[0160] In summary, by using the first set of reference signals, the terminal device can predict the signal quality of the reference signals in the second set of reference signals.

[0161] S202. The network device sends M sets of third reference signals to the terminal device.

[0162] Correspondingly, the terminal device receives M sets of third reference signals from the network device.

[0163] Here, M can represent the number of third reference signal sets. Different third reference signal sets among the M third reference signal sets correspond to different transmission opportunities; that is, each transmission opportunity corresponds to one third reference signal set.

[0164] In some implementations, the transmission timing corresponding to different sets of third reference signals in the M sets of third reference signals refers to consecutive transmission timing.

[0165] The third reference signal set includes multiple reference signals, and the specific number of reference signals included in the third reference signal set is not limited.

[0166] The reference signals in the third set of reference signals can be reference signal measurement data. The reference signals in the third set of reference signals can be used to measure the signal quality of the reference signal; for example, the reference signals in the third set of reference signals can be used to measure the RSRP or SINR of the reference signal.

[0167] In this embodiment, the third reference signal set among the M third reference signal sets can be used to determine the second result. The second result indicates the signal quality measurement result of the reference signals in the third reference signal set.

[0168] Furthermore, the second result can be used to monitor the accuracy of the predictions made by the aforementioned first result.

[0169] In this embodiment, the number of reference signals in the third reference signal set may be less than the number of reference signals in the second reference signal set.

[0170] The reference signals in the third reference signal set are of the same type as those in the second reference signal set. For example, if the reference signals in the second reference signal set are of type CSI-RS, then the reference signals in the third reference signal set are of type CSI-RS; if the reference signals in the second reference signal set are of type SSB, then the reference signals in the third reference signal set are of type SSB.

[0171] Among them, the reference signals in the third set of reference signals are the reference signals for the downlink.

[0172] The reference signals in the third set of reference signals are carried in the downlink channel. This downlink channel can be PBCH, PDCCH, or PDSCH.

[0173] Reference signals in the third set of reference signals can be transmitted via RRC signaling, DCI, or MAC CE.

[0174] In summary, by using the third set of reference signals, the terminal device can monitor the prediction accuracy of the signal quality prediction results of the reference signals in the second set of reference signals based on the actual signal quality measurement results of the reference signals in the third set of reference signals, thereby obtaining the accuracy of the AI ​​model prediction.

[0175] It should be noted that the execution order of steps S201 and S202 is not restricted. For example, step S202 can be executed after step S201, or step S201 can be executed after step S202, or step S202 can be executed simultaneously with step S201. Further details will not be elaborated here.

[0176] S203, The terminal device sends the first information to the network device.

[0177] Correspondingly, the network device receives the first information from the terminal device.

[0178] The first information includes the monitoring results of K first results. It should be understood that the monitoring results can be the monitoring results of the prediction accuracy of all the first results among the K first results, or the monitoring results of the prediction accuracy of some of the first results among the K first results.

[0179] In this embodiment, the first of the K first results is determined based on the time domain position corresponding to the first of the K first results and the time domain position of the first of the M third reference signal sets.

[0180] In one implementation, the time-domain location corresponding to the first result may include the transmission start time of the channel used to carry the first report. The first report includes the first result.

[0181] In some examples, the first report may be a CSI report that includes the first results.

[0182] In some examples, the transmission start time of the channel used to carry the first report can be the starting point of the first orthogonal frequency-division multiplexing symbol (OFDM symbol) of the channel used to carry the first report.

[0183] In another implementation, the time-domain location corresponding to the first result may include a channel state information reference resource for carrying the first report. In some examples, this channel state information reference resource can be understood as the time-domain reference point where the channel state information reference resource for carrying the first report is located.

[0184] In another implementation, the time-domain location corresponding to the first result may include the start time of the first reference signal set closest to the channel state information reference resource used to carry the first report, and the start time of the first reference signal set is not later than the channel state information reference resource used to carry the first report.

[0185] In some examples, the start time of the first reference signal set closest to the channel state information reference resource for carrying the first report can be the start point of the first OFDM symbol of the first reference signal set closest to the channel state information reference resource for carrying the first report.

[0186] For example, please refer to Figure 4, which is a schematic diagram of the time-domain position corresponding to a first result provided in an embodiment of this application. As shown in Figure 4, when the time-domain position corresponding to the first result is the transmission start time of the channel used to carry the first report, the time-domain position corresponding to the first result can be time-domain position 1 shown in Figure 4; when the time-domain position corresponding to the first result is a channel state information reference resource used to carry the first report, the time-domain position corresponding to the first result can be time-domain position 2 shown in Figure 4; when the time-domain position corresponding to the first result is the start time of the first reference signal set closest to the channel state information reference resource used to carry the first report, and the start time of the first reference signal set is not later than the channel state information reference resource used to carry the first report, the time-domain position corresponding to the first result can be time-domain position 3 shown in Figure 4.

[0187] It should be understood that each reference signal in the first set of reference signals is no later than the channel state information reference resource used to carry the first report. For example, the first set of reference signals shown in Figure 4 includes reference signal a, reference signal b, reference signal c, and reference signal d, all of which are no later than the channel state information reference resource used to carry the first report.

[0188] In one implementation, the time-domain position of the third reference signal set among the M third reference signal sets can be the start time of the third reference signal set.

[0189] In some examples, the start time of the third reference signal set can be the start point of the first OFDM symbol of the third reference signal set.

[0190] In another implementation, the time-domain position of the third reference signal set among the M third reference signal sets can be the moment when the second result is obtained through the third reference signal set.

[0191] In some examples, the moment when the second result is obtained through the third reference signal set can be the end moment when the second result is obtained by determining the third reference signal set.

[0192] For example, please refer to Figure 5, which is a schematic diagram of the time-domain position of a third reference signal set provided in an embodiment of this application. As shown in Figure 5, when the time-domain position of the third reference signal set is the start time of the third reference signal set, the time-domain position of the third reference signal set can be time-domain position 4 as shown in Figure 5; when the time-domain position of the third reference signal set is the time when the second result is determined by the third reference signal set, the time-domain position of the third reference signal set can be time-domain position 5 as shown in Figure 5. Wherein, Z' represents the duration for determining the second result through the third reference signal set.

[0193] In one implementation, the first result, the time-domain location corresponding to the first result, and the time-domain location of the first third reference signal set can satisfy the following relationship:

[0194] The first first result is the first result included in the first report whose time-domain position is closest to the time-domain position of the first third reference signal set among the K first results, and the time-domain position corresponding to the first result is no earlier than the time-domain position of the first third reference signal set.

[0195] For example, please refer to Figure 6. Figure 6 is a schematic diagram showing the relationship between the time domain positions of a first result, the time domain position corresponding to the first result, and the time domain position of the first third reference signal set provided in an embodiment of this application. As shown in Figure 6, taking the time domain position corresponding to the first result as time domain position 3 shown in Figure 6 as an example, the time domain position of the first third reference signal set can be time domain position 4 or time domain position 5 shown in Figure 6. The first third reference signal set is the first third reference signal set among M third reference signal sets.

[0196] It can be seen that the first result 1 is the first result included in the first report among the K first results whose time domain position is closest to the time domain position of the first third reference signal set, and the time domain position corresponding to the first result 1 is no earlier than the time domain position of the first third reference signal set. Therefore, the first result 1 is the first first result among the K first results.

[0197] It should be understood that if there is a first result among the K first results, and the time interval between the time domain position of this first result and the time domain position of the first third reference signal set is equal to the time interval between the time domain position of the first first result and the time domain position of the first third reference signal set, but the time domain position of this first result is earlier than the time domain position of the first third reference signal set, then this first result (for example, the first result marked with an "X" as shown in Figure 6) cannot be regarded as the first first result among the K first results.

[0198] Thus, by defining the temporal positional relationship between the first result, the temporal position corresponding to the first result, and the temporal position of the first third reference signal set, it is convenient to determine the monitoring starting point for monitoring the prediction accuracy of the first result at the beginning of the monitoring process.

[0199] In this embodiment, the Kth first result among the K first results is determined based on the time domain position corresponding to the first result and the channel state information reference resource used to carry the first information.

[0200] The time domain location corresponding to the first result can be referred to in the above description, and will not be repeated here.

[0201] The channel state information reference resource used to carry the first information can be understood as the time domain reference point where the channel state information reference resource used to carry the first information is located.

[0202] For example, please refer to FIG7, which is a schematic diagram of the time-domain position of a channel state information reference resource for carrying first information provided in an embodiment of this application. As shown in FIG7, the time-domain position of the channel state information reference resource for carrying first information is after the time-domain position of the Mth third reference signal set, and the time-domain position of the channel state information reference resource for carrying first information is before the time-domain position of the channel for carrying first information.

[0203] The time-domain location of the channel used to carry the first information can be the start time of transmission of the channel used to carry the first information. For example, the time-domain location of the channel used to carry the first information can be time-domain location 6 as shown in Figure 7.

[0204] In one implementation, the Kth first result, the time-domain location corresponding to the first result, and the channel state information reference resource used to carry the first information can satisfy the following relationship:

[0205] The Kth first result is the first result included in the first report whose time-domain location is closest to the channel state information reference resource used to carry the first information, and the transmission start time of the channel used to carry the first report is not later than the channel state information reference resource used to carry the first information.

[0206] In this embodiment, when the Kth first result is determined, the time domain position corresponding to the first result is the transmission start time of the channel used to carry the first report.

[0207] For example, please refer to Figure 8. Figure 8 is a schematic diagram showing the relationship between the Kth first result, the time domain position corresponding to the first result, and the channel state information reference resource for carrying the first information, according to an embodiment of this application. As shown in Figure 8, based on the content shown in Figure 6, taking the time domain position corresponding to the first result as time domain position 1 shown in Figure 8 as an example, it can be seen that the first result 7 is the first result included in the first report whose time domain position is closest to the channel state information reference resource for carrying the first information among the K first results. Furthermore, the transmission start time of the channel used to carry the first report (i.e., time domain position 1 shown in Figure 8) is not later than the channel state information reference resource used to carry the first information. Therefore, the first result 7 is the Kth first result among the K first results.

[0208] It should be understood that, if there is a first result among the K first results, for which the time interval between the time domain position of this first result and the channel state information reference resource carrying the first information is equal to the time interval between the time domain position of the K-th first result and the channel state information reference resource carrying the first information, but the time domain position of this first result is later than the channel state information reference resource carrying the first information, then this first result (for example, the first result marked with "X" as shown in Figure 8) cannot be regarded as the K-th first result among the K first results.

[0209] In this way, by limiting the time domain position relationship among the K-th first result, the time domain position corresponding to the first result and the channel state information reference resource carrying the first information, it is convenient to determine the monitoring end point for monitoring the prediction accuracy of the first result before the end of the monitoring process.

[0210] It should be noted that, in some possible implementation manners, the first first result and the K-th first result may be the same first result.

[0211] In conclusion, by determining the monitoring start point and monitoring end point for monitoring the prediction accuracy of the first result, a time domain range for monitoring the prediction accuracy of the first result can be preliminarily determined, thereby realizing monitoring of the prediction accuracy of the first result within a continuous time domain range, which can ensure the effectiveness of monitoring.

[0212] Further, in order to monitor the prediction accuracy of the first result more accurately, the terminal device can associate the first result within the above time domain range with the second result, so as to targetedly monitor the prediction accuracy of each first result.

[0213] Wherein, as an implementation manner, the second result corresponding to each first result within the above time domain range may be firstly determined from M second results, that is, the second result corresponding to the k-th first result is determined from M second results, and then the second result corresponding to the first result is used to monitor the prediction accuracy of the first result, so as to obtain the monitoring result of the first result.

[0214] In this way, the monitoring result of the k-th first result among the K first results can be determined, and the k-th first result can be any one of the K first results. Wherein, the value range of K is 0 < k ≤ K, and both k and K are positive integers.

[0215] Wherein, the second result corresponding to the k-th first result may be determined according to the time domain position corresponding to the k-th first result and the time domain position of the third reference signal set in the M third reference signal sets.

[0216] In one possible implementation, the second result corresponding to the k-th first result, the time-domain position corresponding to the k-th first result, and the time-domain position of the third reference signal set in the M sets of third reference signals can satisfy the following relationship:

[0217] The second result corresponding to the kth first result is the signal quality measurement result of the reference signal in the third reference signal set whose time domain position is closest to the time domain position corresponding to the kth first result among the M third reference signal sets.

[0218] For example, please refer to Figure 9, which is a schematic diagram showing the relationship between the second result corresponding to the k-th first result, the time-domain position corresponding to the k-th first result, and the time-domain position of the third reference signal set provided in an embodiment of this application. As shown in Figure 9, taking the time-domain position corresponding to the k-th first result as time-domain position 2 shown in Figure 9 as an example, assuming that the second result 2 is the signal quality measurement result corresponding to the reference signal in the third reference signal set whose time-domain position is closest to the time-domain position corresponding to the k-th first result among the M third reference signal sets, then the second result 2 is the second result corresponding to the k-th first result. However, the second result 1 is not the signal quality measurement result corresponding to the reference signal in the third reference signal set whose time-domain position is closest to the time-domain position corresponding to the k-th first result among the M third reference signal sets, therefore the second result 1 is not the second result corresponding to the k-th first result.

[0219] Furthermore, in another possible implementation, the second result corresponding to the k-th first result, the time-domain position corresponding to the k-th first result, and the time-domain position of the third reference signal set in the M sets of third reference signals can satisfy the following relationship:

[0220] The second result corresponding to the k-th first result is the signal quality measurement result of the reference signal in the third reference signal set whose time domain position is closest to the time domain position corresponding to the k-th first result among the M third reference signal sets, and the time interval between the time domain position of the third reference signal set among the M third reference signal sets and the time domain position corresponding to the k-th first result is less than a first time threshold. The specific value of the first time threshold is not limited.

[0221] In this way, since the second result corresponding to the third reference signal set whose time interval between the time domain position corresponding to the kth first result is greater than the first time threshold can be excluded, the accuracy of determining the second result corresponding to the kth first result can be improved.

[0222] In some examples, the initial threshold can be determined by the terminal device and reported to the network device.

[0223] In other examples, the first time threshold can be configured by the network device.

[0224] Furthermore, in another possible implementation, the following relationship can be satisfied between the second result corresponding to the kth first result, the time-domain position corresponding to the kth first result, and the time-domain position of the third reference signal set in the M third reference signal sets:

[0225] The second result corresponding to the kth first result is the signal quality measurement result of the reference signal in the third reference signal set whose time domain position is closest to the time domain position corresponding to the kth first result among the M third reference signal sets; the time interval between the time domain position of the third reference signal set among the M third reference signal sets and the time domain position corresponding to the kth first result is less than the first time threshold; and the time domain position of the third reference signal set among the M third reference signal sets is no later than the time domain position corresponding to the (k+1)th first result.

[0226] In this way, since the second result corresponding to the third reference signal set whose time interval between the time domain position corresponding to the kth first result is greater than the first time threshold can be excluded, and the problem of not being able to match the kth first result with the second result due to the (k+1)th first result covering the kth first result can be avoided, the accuracy of determining the second result corresponding to the kth first result can be further improved.

[0227] Furthermore, in some examples, the second result corresponding to different first results can be the same second result.

[0228] In other examples, there may not be a second result corresponding to the first result within the aforementioned time domain.

[0229] Furthermore, the monitoring results of the K first results may include beam prediction parameters, which can be used to indicate the prediction accuracy of the first results.

[0230] It should be understood that terminal devices can determine beam prediction parameters before sending the first information to network devices.

[0231] As one possible implementation, the terminal device can increment the value of the first counter by one to obtain a first counting parameter when there is a second result corresponding to the first result among the K first results; increment the value of the second counter by one to obtain a second counting parameter when the first result and the second result corresponding to the first result satisfy a first condition; and determine the beam prediction parameter based on the second counting parameter and the first counting parameter when the value of the first counting parameter is accumulated to L or when all K first results have been traversed.

[0232] In one implementation, the first condition may include: at least one of the reference signals from the third set of reference signals whose signal quality measurement results are among the top X largest exists in a fourth set of reference signals, and the fourth set of reference signals includes the reference signals from the third set whose signal quality prediction results are among the top P largest. The signal quality prediction results may include prediction probabilities, such as the probability that a reference signal is the best reference signal.

[0233] In some possible implementations, the terminal device determines the beam prediction parameter based on the second counting parameter and the first counting parameter, which may include: the terminal device determining the ratio of the second counting parameter to the first counting parameter as the beam prediction parameter.

[0234] In some other possible implementations, the terminal device determines the beam prediction parameters based on the second counting parameter and the first counting parameter, which may include: the terminal device determining the second counting parameter and the first counting parameter as beam prediction parameters.

[0235] Where the terminal device determines the second counting parameter and the first counting parameter as beam prediction parameters, the number of bits for both the first counting parameter and the second counting parameter can be [number missing]. bits, of which This indicates rounding up, where L is a positive integer, and the specific value of L is not limited. In some examples, the value of L can be configured by the network device.

[0236] By defining the conditions for determining beam prediction parameters, it is easier to standardize the data block size, thereby reducing signaling interactions and saving communication resources.

[0237] Based on the above, the terminal device can determine the prediction accuracy of the first result through beam prediction parameters, thereby obtaining the accuracy of the signal quality prediction result of the reference signal.

[0238] In summary, the communication method provided in this application embodiment can determine the relationship between the signal quality measurement result and the signal quality prediction result during the signal quality prediction result monitoring process, so that the terminal device can effectively compare the signal quality prediction result with the signal quality measurement result corresponding to the signal quality prediction result, thereby obtaining the accuracy of the signal quality prediction result of the reference signal.

[0239] In addition, to address the above-mentioned problems, this application provides another communication method.

[0240] In this communication method, the network device can send M sets of third reference signals to the terminal device. Different sets of the M third reference signals correspond to different transmission timings. The terminal device receives the M sets of third reference signals. The terminal device can measure the signal quality of the reference signal in each of the M sets of third reference signals to obtain a signal quality measurement result (also known as a second result).

[0241] The terminal device can also predict the signal quality of the reference signals in the second set of reference signals based on the historical signal quality measurement results of the reference signals in at least one first set of reference signals, and obtain the signal quality prediction result (also known as the fourth result).

[0242] Furthermore, the terminal device can use the second result to monitor the accuracy of the prediction of the fourth result, and upon obtaining the monitoring result of the accuracy of the fourth result, send the second information to the network device.

[0243] By establishing the relationship between signal quality measurement results and signal quality prediction results during the signal quality prediction monitoring process, the terminal device can effectively compare the signal quality prediction results with the corresponding signal quality measurement results, thereby determining the accuracy of the signal quality prediction results for the reference signal.

[0244] Scene 2:

[0245] The signal quality measurement results of a reference signal in a first set of reference signals can be used to predict the signal quality of a reference signal in a second set of reference signals, thus obtaining the signal quality prediction results of the reference signals in the second set of reference signals, and multiple signal quality prediction results correspond to a channel state information report.

[0246] Please refer to Figure 10, which is a signaling interaction diagram of another communication method provided in an embodiment of this application. This communication method can be applied to the communication system shown in Figure 1. As shown in Figure 10, the communication method includes:

[0247] S301. The network device sends M sets of third reference signals to the terminal device.

[0248] Correspondingly, the terminal device receives M sets of third reference signals from the network device.

[0249] The terminal device can be the terminal device 10 shown in Figure 1 above, and the network device can be the network device 20 shown in Figure 1 above.

[0250] Here, M can represent the number of third reference signal sets. Different third reference signal sets among the M third reference signal sets correspond to different transmission opportunities; that is, each transmission opportunity corresponds to one third reference signal set.

[0251] In some implementations, the transmission timing corresponding to different sets of third reference signals in the M sets of third reference signals refers to consecutive transmission timing.

[0252] The third reference signal set includes multiple reference signals, and the specific number of reference signals included in the third reference signal set is not limited.

[0253] The reference signals in the third set of reference signals can be reference signal measurement data. The reference signals in the third set of reference signals can be used to measure the signal quality of the reference signal; for example, the reference signals in the third set of reference signals can be used to measure the RSRP or SINR of the reference signal.

[0254] The reference signals in the third set of reference signals mentioned above are used to measure indicators only as examples. In actual implementation, they may also be used to measure other indicators related to channel quality, which will not be elaborated here.

[0255] The reference signal type in the third reference signal set can be either SSB or CSI-RS.

[0256] In this embodiment, the third reference signal set among the M third reference signal sets is used to determine the second result. The second result indicates the signal quality measurement result of the reference signals in the third reference signal set.

[0257] Furthermore, the second result can be used to monitor the accuracy of the prediction of the fourth result in the third result.

[0258] In this embodiment, the third result is predicted based on one or more historical signal quality measurement results corresponding to reference signals in the first reference signal set. The first reference signal set may include one or more reference signals, each corresponding to a beam. The multiple reference signals in the first reference signal set are historical reference signals from the network device; therefore, the third result is predicted based on signal quality measurement results corresponding to one or more historical reference signals in the first reference signal set.

[0259] Furthermore, the specific details of the first reference signal set can be found in the relevant description of S201 in the foregoing embodiments, and will not be repeated here.

[0260] The third result can be used to indicate the signal quality prediction result of the reference signal in the second set of reference signals corresponding to the first set of reference signals. In some examples, the third result can be the RSRP or SINR of the reference signal in the second set of reference signals corresponding to the first set of reference signals.

[0261] The second reference signal set can be a set of reference signals predicted based on the signal quality measurement results of the reference signals in the first reference signal set. The second reference signal set may include multiple reference signals.

[0262] In one implementation, the terminal device can use an AI model to predict the signal quality of multiple reference signals located after the first reference signal set in the time domain, based on the signal quality measurement results of the reference signals in the first reference signal set, to obtain the signal quality prediction results of each of the multiple reference signals, which is the fourth result. The third result includes multiple fourth results.

[0263] The second set of reference signals includes the aforementioned multiple reference signals. It should be understood that the time-domain position following the first set of reference signals can be a future time-domain position relative to the current time-domain position, or a historical time-domain position relative to the current time-domain position.

[0264] Furthermore, the specific details of the second reference signal set can be found in the relevant description of S201 in the foregoing embodiments, and will not be repeated here.

[0265] In this embodiment, the third result may include at least one fourth result, and different fourth results in the at least one fourth result correspond to different time domain locations.

[0266] For example, please refer to Figure 11, which is an example diagram of the positional relationship between the third result and the fourth result provided in the embodiments of this application. As shown in Figure 11, the third result may include the fourth result 1, the fourth result 2, the fourth result 3, and the fourth result 4. The time domain position corresponding to the fourth result 1 is the time domain position "a" shown in Figure 11, the time domain position corresponding to the fourth result 2 is the time domain position "b" shown in Figure 11, the time domain position corresponding to the fourth result 3 is the time domain position "c" shown in Figure 11, and the time domain position corresponding to the fourth result 4 is the time domain position "d" shown in Figure 11.

[0267] It can be seen that, in the time domain, time domain positions a, b, c, and d correspond to different time domain positions, that is, different fourth results in at least one fourth result correspond to different time domain positions.

[0268] The number of reference signals in the third reference signal set can be less than the number of reference signals in the second reference signal set. Similarly, the number of reference signals in the first reference signal set can also be less than the number of reference signals in the second reference signal set.

[0269] The reference signals in the third reference signal set are of the same type as those in the second reference signal set. For example, if the reference signals in the second reference signal set are of type CSI-RS, then the reference signals in the third reference signal set are of type CSI-RS; if the reference signals in the second reference signal set are of type SSB, then the reference signals in the third reference signal set are of type SSB.

[0270] Among them, the reference signals in the third set of reference signals are the reference signals for the downlink.

[0271] The reference signals in the third set of reference signals are carried in the downlink channel. This downlink channel can be PBCH, PDCCH, or PDSCH.

[0272] Reference signals in the third set of reference signals can be transmitted via RRC signaling, DCI, or MAC CE.

[0273] In summary, by using the third set of reference signals, the terminal device can monitor the prediction accuracy of the signal quality prediction results of the reference signals in the second set of reference signals based on the actual signal quality measurement results of the reference signals in the third set of reference signals, thereby obtaining the accuracy of the AI ​​model prediction.

[0274] S302, The terminal device sends the second information to the network device.

[0275] Correspondingly, the network device receives the second information from the terminal device.

[0276] The second piece of information includes the monitoring results of K fourth results.

[0277] It should be understood that the monitoring results can be the monitoring results of the prediction accuracy of all the fourth results among the K fourth results, or the monitoring results of the prediction accuracy of some of the K fourth results.

[0278] In this embodiment, the first of the K fourth results is determined based on the time domain position corresponding to the fourth result and the time domain position of the first of the M third reference signal sets.

[0279] In one possible implementation, the time-domain location corresponding to the fourth result may include a symbol of the time-domain location corresponding to the fourth result.

[0280] For example, continuing with Figure 11, the time-domain location corresponding to the fourth result 1 in Figure 11 can be a symbol of time-domain location "a". Optionally, the time-domain location corresponding to the fourth result 1 can be an OFDM symbol in time-domain location "a". For example, the time-domain location corresponding to the fourth result 1 can be the first OFDM symbol or the last OFDM symbol in time-domain location "a".

[0281] In one implementation, the time-domain position of the first third reference signal set among the M third reference signal sets can be the start time of the third reference signal set.

[0282] In some examples, the start time of the third reference signal set can be the start point of the first OFDM symbol of the third reference signal set.

[0283] In another implementation, the time-domain position of the first third reference signal set among the M third reference signal sets can be the moment when the second result is obtained through the third reference signal set.

[0284] In some examples, the moment when the second result is obtained using the third reference signal set can be the moment when the end of obtaining the second result is determined using the third reference signal set. The time-domain location of the third reference signal set can be referred to the relevant description in Figure 6 above, and will not be repeated here.

[0285] In one implementation, the first fourth result, the time-domain location corresponding to the fourth result, and the time-domain location of the first third reference signal set can satisfy the following relationship:

[0286] The first fourth result is the first fourth result included in the second report among the K fourth results whose time-domain location is closest to the time-domain location of the first third reference signal set, and the time-domain location corresponding to the fourth result is no earlier than the time-domain location of the first third reference signal set. The second report includes at least one fourth result.

[0287] In some examples, the second report may be a CSI report that includes at least one fourth result.

[0288] Please refer to Figure 12. Figure 12 is a schematic diagram showing the relationship between the time domain positions of a first fourth result, the time domain position corresponding to the fourth result, and the time domain position of the first third reference signal set provided in an embodiment of this application. As shown in Figure 12, the time domain position of the first third reference signal set can be time domain position 4 or time domain position 5 shown in Figure 12, and the first third reference signal set is the first third reference signal set among M third reference signal sets.

[0289] It can be seen that the fourth result 1 is the first fourth result included in the second report among the K fourth results whose time domain position is closest to the time domain position of the first third reference signal set, and the time domain position corresponding to the fourth result 1 is no earlier than the time domain position of the first third reference signal set. Therefore, the fourth result 1 is the first fourth result among the K fourth results.

[0290] Thus, by defining the temporal positional relationship between the first fourth result, the temporal position corresponding to the fourth result, and the temporal position of the first third reference signal set, it is convenient to determine the monitoring starting point for monitoring the prediction accuracy of the fourth result at the beginning of the monitoring process.

[0291] In this embodiment, the Kth fourth result among the K fourth results is determined based on the transmission start time of the channel used to carry the second report and the channel state information reference resource used to carry the second information.

[0292] The transmission start time of the channel used to carry the second report can be the starting point of the first OFDM symbol of the channel used to carry the second report.

[0293] The channel state information reference resource used to carry the second information can be understood as the time domain reference point where the channel state information reference resource used to carry the second information is located.

[0294] For example, please refer to Figure 13, which is a schematic diagram of the time-domain position of a channel state information reference resource for carrying second information according to an embodiment of this application. As shown in Figure 13, the time-domain position of the channel state information reference resource for carrying second information is after the time-domain position of the Mth third reference signal set, and before the time-domain position of the channel for carrying second information. The time-domain position of the channel for carrying second information can be the transmission start time of the channel. For example, the time-domain position of the channel for carrying second information can be time-domain position 7 shown in Figure 13.

[0295] In one implementation, the following relationship can be satisfied between the Kth fourth result, the transmission start time of the channel for carrying the second report, and the channel state information reference resource for carrying the second information:

[0296] The Kth fourth result is the last fourth result included in the second report among the K fourth results whose time-domain location is closest to the channel state information reference resource used to carry the second information, and the transmission start time of the channel used to carry the second report is not later than the channel state information reference resource used to carry the second information. The second report includes at least one fourth result.

[0297] For example, please refer to FIG. 14. FIG. 14 is a schematic diagram of a relationship among time-domain positions of a K-th fourth result, a transmission start time of a channel carrying a second report, and a channel state information reference resource carrying second information according to an embodiment of the present application. As shown in FIG. 14, based on the content shown in FIG. 13, it can be seen that the fourth result 8 is the last fourth result included in one second report that is closest to the channel state information reference resource carrying the second information in terms of time-domain position among the K fourth results, and the transmission start time of the channel carrying the second report is no later than the channel state information reference resource carrying the second information, so the fourth result 8 is the K-th fourth result among the K fourth results.

[0298] In this way, by defining the time-domain position relationship among the K-th fourth result, the transmission start time of the channel carrying the second report, and the channel state information reference resource carrying the second information, it is convenient to determine the monitoring end point for monitoring the prediction accuracy of the fourth result before the end of the monitoring process.

[0299] In conclusion, by determining the monitoring start point and the monitoring end point for monitoring the prediction accuracy of the fourth result, a time-domain range for monitoring the prediction accuracy of the fourth result can be preliminarily determined, so that the prediction accuracy of the fourth result can be monitored in a continuous time-domain range, thereby ensuring the effectiveness of monitoring.

[0300] Further, in order to monitor the prediction accuracy of the fourth result more accurately, a terminal device may associate the fourth result in the above time-domain range with a second result, so as to specifically monitor the prediction accuracy of each fourth result.

[0301] Wherein, as an implementation manner, the second result corresponding to each fourth result in the above time-domain range may be first determined from M second results, that is, the second result corresponding to the k-th fourth result is determined from the M second results, and then the prediction accuracy of the fourth result is monitored by using the second result corresponding to the fourth result, so as to obtain a monitoring result of the fourth result.

[0302] Through this method, the monitoring result of the k-th fourth result among the K fourth results can be determined, and the k-th fourth result may be any one of the K fourth results. Wherein, the value range of K may be 0<k≤K, and both k and K are positive integers.

[0303] Wherein, the second result corresponding to the k-th fourth result may be determined according to the time-domain position corresponding to the k-th fourth result and the time-domain positions of third reference signal sets in the M third reference signal sets, k is less than or equal to K, and both k and K are positive integers.

[0304] In one possible implementation, the second result corresponding to the kth fourth result can be the signal quality measurement result of the reference signal in the set of M third reference signals whose time domain position is closest to the time domain position corresponding to the kth fourth result.

[0305] For example, please refer to Figure 15. Figure 15 is a schematic diagram showing the relationship between the time domain positions of the second result corresponding to the kth fourth result, the time domain position corresponding to the kth fourth result, and the time domain positions of the third reference signal set in the M third reference signal sets provided in an embodiment of this application.

[0306] Based on the content shown in Figure 14, as shown in Figure 15, assuming that the kth fourth result is the fourth result 4 shown in Figure 15, it can be seen that the third reference signal set t is the third reference signal set whose time domain position is closest to the time domain position corresponding to the fourth result 4 among the M third reference signal sets. Therefore, the signal quality measurement result corresponding to the reference signal in the third reference signal set t can be taken as the second result corresponding to the fourth result 4.

[0307] Neither the third reference signal set s nor the third reference signal set M is the third reference signal set whose time domain position is closest to the time domain position corresponding to the fourth result 4 among the M third reference signal sets. Therefore, the signal quality measurement result corresponding to the reference signal in the third reference signal set s cannot be used as the second result corresponding to the fourth result 4, and the signal quality measurement result corresponding to the reference signal in the third reference signal set M cannot be used as the second result corresponding to the fourth result 4.

[0308] Furthermore, in another possible implementation, the second result corresponding to the kth fourth result can be the signal quality measurement result of the reference signal in the third reference signal set whose time domain position is closest to the time domain position corresponding to the kth fourth result among the M third reference signal sets, and the time interval between the time domain position of the third reference signal set among the M third reference signal sets and the time domain position corresponding to the kth fourth result is less than the second time threshold.

[0309] The specific value of the second time threshold is not limited.

[0310] In some examples, the second time threshold can be determined by the terminal device and reported to the network device.

[0311] In other examples, the second time threshold can be configured by the network device.

[0312] In some examples, the second time threshold can be the same as the first time threshold mentioned above.

[0313] In other examples, the second time threshold may be different from the aforementioned first time threshold.

[0314] In this way, since the second result corresponding to the third reference signal set whose time interval between the time domain position corresponding to the kth fourth result is greater than the second time threshold can be excluded, the accuracy of determining the second result corresponding to the kth fourth result can be improved.

[0315] Furthermore, in another possible implementation, the second result corresponding to the k-th fourth result can be the signal quality measurement result of the reference signal in the third reference signal set whose time domain position is closest to the time domain position corresponding to the k-th fourth result among the M third reference signal sets. The time interval between the time domain position of the third reference signal set among the M third reference signal sets and the time domain position corresponding to the k-th fourth result is less than the second time threshold, and the time when the second result is determined by the third reference signal set is no later than the channel state information reference resource of the next second report after the second report.

[0316] This avoids the problem that the gap between the kth fourth result and the second result corresponding to the kth fourth result is too large to be effectively compared, thus further improving the accuracy of determining the second result corresponding to the kth fourth result.

[0317] Furthermore, in some examples, the second result corresponding to different fourth results can be the same second result.

[0318] In other examples, there may not be a second result corresponding to the fourth result in the aforementioned time domain range.

[0319] Furthermore, the monitoring results of the K fourth results may include beam prediction parameters, which can be used to indicate the prediction accuracy of the fourth results.

[0320] It should be understood that the terminal device can determine the beam prediction parameters before sending the second information to the network device.

[0321] As one possible implementation, the terminal device can increment the value of the first counter by one to obtain a first counting parameter when there is a second result corresponding to the fourth result among the K fourth results; increment the value of the second counter by one to obtain a second counting parameter when the fourth result and the second result corresponding to the fourth result satisfy a first condition; and determine the beam prediction parameter based on the second counting parameter and the first counting parameter when the value of the first counting parameter is accumulated to L or when all K first results have been traversed.

[0322] In one implementation, the first condition may include: at least one of the reference signals in the third reference signal set whose signal quality measurement results are among the top X largest exists in the fourth reference signal set, and the fourth reference signal set includes the reference signals in the third reference signal set whose signal quality prediction results are among the top P largest.

[0323] The signal quality prediction result may include prediction probabilities, such as the probability that the reference signal is the best reference signal.

[0324] In some possible implementations, the terminal device determines the beam prediction parameter based on the second counting parameter and the first counting parameter, which may include: the terminal device determining the ratio of the second counting parameter to the first counting parameter as the beam prediction parameter.

[0325] In some other possible implementations, the terminal device determines the beam prediction parameters based on the second counting parameter and the first counting parameter, which may include: the terminal device determining the second counting parameter and the first counting parameter as beam prediction parameters.

[0326] Where the terminal device determines the second counting parameter and the first counting parameter as beam prediction parameters, the number of bits for both the first counting parameter and the second counting parameter can be [number missing]. bits, of which This indicates rounding up, where L is a positive integer, and the specific value of L is not limited.

[0327] In some examples, the value of L can be configured by the network device.

[0328] By defining the conditions for determining beam prediction parameters, it is easier to standardize the data block size, thereby reducing signaling interactions and saving communication resources.

[0329] Based on the above, the terminal device can determine the prediction accuracy of the fourth result through beam prediction parameters, thereby obtaining the accuracy of the signal quality prediction result of the reference signal.

[0330] In summary, the communication method provided in this application embodiment can determine the relationship between the signal quality measurement result and the signal quality prediction result during the signal quality prediction result monitoring process, so that the terminal device can effectively compare the signal quality prediction result with the signal quality measurement result corresponding to the signal quality prediction result, thereby obtaining the accuracy of the signal quality prediction result of the reference signal.

[0331] By way of example, embodiments of this application also provide a communication device.

[0332] Please refer to Figure 16, which is a schematic diagram of the structure of a communication device provided in an embodiment of this application.

[0333] As shown in Figure 16, the communication device 700 can exist independently or be integrated into other devices. It can communicate with the network devices mentioned above to implement the operations corresponding to the terminal devices in any of the above method embodiments.

[0334] The communication device 700 may include a transceiver unit 701. The communication device 700 may also include a processing unit. The transceiver unit 701 can implement corresponding communication functions, and the processing unit is used for data processing.

[0335] Optionally, the communication device 700 may further include a storage unit, which can be used to store instructions and / or data. The processing unit can read the instructions and / or data in the storage unit so that the communication device 700 can implement the aforementioned method embodiments.

[0336] The communication device 700 can be used to perform the actions performed by the terminal device in the preceding method embodiments. The communication device 700 can be the terminal device or a component configurable on the terminal device. The transceiver unit 701 is used to perform reception-related operations of the terminal device in the preceding method embodiments, and the processing unit is used to perform processing-related operations of the terminal device in the preceding method embodiments.

[0337] Optionally, the transceiver unit 701 may include a sending unit and a receiving unit. The sending unit is used to perform the sending operation in the above method embodiments. The receiving unit is used to perform the receiving operation in the above method embodiments.

[0338] It should be noted that the communication device 700 may include a transmitting unit but not a receiving unit. Alternatively, the communication device 700 may include a receiving unit but not a transmitting unit. Specifically, it depends on whether the above-described scheme executed by the communication device 700 includes both transmitting and receiving actions.

[0339] As an example, the communication device 700 is used to perform the actions performed by the terminal device in the embodiments shown in FIG2 or FIG10 above.

[0340] The communication device 700 may include a transceiver unit 701.

[0341] The transceiver unit 701 is configured to receive at least one first reference signal set from a network device, wherein the first reference signal set in the at least one first reference signal set is used to determine a first result, the first result being predicted based on a signal quality measurement result corresponding to a reference signal in the first reference signal set, and the first result being used to indicate a signal quality prediction result of a reference signal in a second reference signal set corresponding to the first reference signal set.

[0342] The transceiver unit 701 is also used to receive M sets of third reference signals from the network device. The M sets of third reference signals correspond to different transmission timings. The third reference signal set among the M sets of third reference signals is used to determine the second result. The second result is used to indicate the signal quality measurement result of the reference signal in the third set of third reference signals. The second result is used to monitor the prediction accuracy of the first result.

[0343] The transceiver unit 701 is further configured to send first information to the network device. The first information includes monitoring results of K first results. The first first result among the K first results is determined based on the time-domain position corresponding to the first result among the K first results and the time-domain position of the first third reference signal set among the M third reference signal sets. The Kth first result among the K first results is determined based on the time-domain position corresponding to the first result and the channel state information reference resource used to carry the first information. The monitoring result of the kth first result among the K first results is determined based on the kth first result and the second result corresponding to the kth first result among the M second results. The second result corresponding to the kth first result is determined based on the time-domain position corresponding to the kth first result and the time-domain position of the third reference signal set among the M third reference signal sets. k is less than or equal to K, and both k and K are positive integers.

[0344] It should be understood that the corresponding processes performed by each unit have been described in detail in the above method embodiments, and will not be repeated here for the sake of brevity.

[0345] The processing unit in the preceding embodiments can be implemented by at least one processor or processor-related circuitry. The transceiver unit 701 can be implemented by a transceiver or transceiver-related circuitry. The transceiver unit can also be referred to as a communication unit or communication interface. The storage unit can be implemented by at least one memory.
