Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a beam measurement method, a beam measurement device, and a storage medium. Background Art

[0002] In new radio (NR) technology, for example, when the communication frequency band is in frequency range 2 (FR2), beam-based transmission and reception are required to ensure coverage due to the rapid attenuation of high-frequency channels.

[0003] In related technologies, during beam management, a network device configures a reference signal resource set for beam measurement. The terminal then measures the reference signal resources in the reference signal resource set and reports a positive integer number of reference signal resource identifiers (IDs) with relatively strong reference signal received power (RSRP) and / or signal-to-interference noise ratio (SINR) and the corresponding layer 1 RSRP (Layer 1-RSRP, L1-RSRP) and / or layer 1 SINR (Layer 1-SINR, L1-SINR). The reference signals included in the reference signal resource set configured by the network device are typically sent periodically, meaning that the same number of reference signal resources with the same beam direction are sent each time. If the number of reference signal resources in the reference signal resource set is too small, the beam measured by the terminal will be inaccurate. If the number of reference signal resources in the reference signal resource set is too large, the reference signal resource overhead is high, and the terminal measurement complexity and power consumption are also high.

[0114] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0115] The beam indication method provided by the embodiment of the present disclosure can be applied to Figure 1 In the wireless communication system shown in FIG. Figure 1 As shown in FIG, the wireless communication system includes a terminal and a network device. The terminal is connected to the network device via wireless resources and performs data transmission and reception.

[0116] It is understandable that Figure 1 The wireless communication system shown is only for schematic illustration. The wireless communication system may also include other network devices, such as core network devices, wireless relay devices, and wireless backhaul devices. Figure 1 The embodiment of the present disclosure does not limit the number of network devices and terminals included in the wireless communication system.

[0117] It can be further understood that the wireless communication system of the embodiment of the present disclosure is a network that provides wireless communication functions. The wireless communication system can adopt different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), carrier sense multiple access / collision avoidance (Carrier Sense Multiple Access with Collision Avoidance). According to factors such as the capacity, rate, and latency of different networks, the network can be divided into 2G (English: generation) network, 3G network, 4G network or future evolution network, such as 5G network, which can also be called New Radio (NR). For the convenience of description, the present disclosure sometimes refers to the wireless communication network as simply a network.

[0118] Furthermore, the network devices involved in the present disclosure may also be referred to as wireless access network devices. The wireless access network devices may be: base stations, evolved node Bs (eNBs), home base stations, access points (APs) in wireless fidelity (WIFI) systems, wireless relay nodes, wireless backhaul nodes, transmission points (TPs) or transmission and reception points (TRPs), etc. They may also be gNBs in NR systems, or they may be components or a portion of a base station. In the case of a vehicle-to-everything (V2X) communication system, the network devices may also be vehicle-mounted devices. It should be understood that in the embodiments of the present disclosure, there is no limitation on the specific technology and specific device form used by the network devices.

[0119] Furthermore, the terminal involved in the present disclosure may also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., which is a device that provides voice and / or data connectivity to users. For example, the terminal can be a handheld device with wireless connection function, a vehicle-mounted device, etc. At present, some examples of terminals are: smart phones (Mobile Phones), pocket personal computers (PPCs), handheld computers, personal digital assistants (PDAs), laptops, tablet computers, wearable devices, or vehicle-mounted devices, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be a vehicle-mounted device. It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

[0120] In the present disclosure, data transmission between a network device and a terminal is based on a beam. Beam management is required during the beam-based data transmission between the network device and the terminal. In related technologies, during beam management, a base station or other network device configures a reference signal resource set for beam measurement. The terminal measures the reference signal resources in the reference signal resource set and then reports the X reference signal resource IDs and corresponding L1-RSRP and / or L1-SINR that are relatively strong. However, the reference signals contained in the reference signal resource set configured by the network device are generally periodic, that is, the same number of reference signal resources with the same beam direction are sent each time. If the number of reference signal resources is too small, the beam measured by the terminal is not accurate enough. If the number of reference signal resources is too large, the reference signal resource overhead is large, and the complexity and power consumption of the terminal measurement are also high.

[0121] Among them, in the related technology, the reference signal resources configured by the network equipment for the terminal for beam measurement do not take into account the feedback information of the terminal, resulting in a large number of reference signal resources, resulting in high signaling overhead and high terminal measurement complexity, or the number of reference signal resources is too small, resulting in inaccurate measurement results.

[0122] In view of this, embodiments of the present disclosure provide a beam measurement method in which reference signal resources for beam measurement are configured based on beam measurement reference signal resources fed back by a terminal. The terminal uses the actual measurement results of a small number of reference signal resources and the model based on a model to estimate beam measurement results for other reference signal resources. The terminal then feeds back reference signal resource information corresponding to the small number of reference signal resources corresponding to the actual measurement results to a network device, which then configures the reference signal resources corresponding to the beam measurement results of the measured reference signal resources for beam measurement. This method reduces the signaling overhead of beam measurement reference signal resources and reduces the complexity of terminal measurement while ensuring beam measurement accuracy.

[0123] Figure 2 FIG. 1 is a flow chart showing a beam measurement method according to an exemplary embodiment. Figure 2 As shown, the beam measurement method is used in a terminal and includes the following steps.

[0124] In step S11, first configuration information sent by a network device is received.

[0125] The first configuration information is used to configure a first reference signal resource set. Reference signal resources in the first reference signal resource set are used for beam measurement, and the number of reference signal resources in the first reference signal resource set is a first number.

[0126] In step S12, beam measurement is performed on the first number of reference signal resources respectively.

[0127] In step S13, the first number of reference signal resource measurement results obtained by measurement is input into the first model to obtain a second number of reference signal resource measurement results, wherein the second number is greater than or equal to the first number.

[0128] In step S14, a measurement report is sent to the network device, where the measurement report includes the third number of reference signal resource measurement results.

[0129] The third number of reference signal resource measurement results is a subset of the second number of reference signal resource measurement results.

[0130] In the beam measurement method provided in the embodiments of the present disclosure, a terminal receives first configuration information sent by a network device, measures a first number of reference signal resources in a first reference signal resource set in the first configuration information, inputs the measurement results of the measured reference signal resources into a first model, and obtains measurement results of reference signal resources greater than or equal to the first number (a second number). Based on the measurement results of the second number of reference signal resources, the terminal feeds back to the network device the measurement results of the reference signal resources with the strongest signal strength among the second number of reference signal resource measurement results. The number of measurement results of the reference signal resources with the strongest signal strength among the second number of reference signal resource measurement results is a third number.

[0131] In the beam measurement method provided by the embodiment of the present disclosure, the reference signal resources in the first number of reference signal resources may be included in the second number of reference signal resources, or may not be included in the second number of reference signal resources.

[0132] In the beam measurement method provided by the embodiment of the present disclosure, the third number of reference signal resource measurement results is a subset of the second number of reference signal resource measurement results.

[0133] In the beam measurement method provided by the embodiment of the present disclosure, the third number of reference signal resource measurement results fed back by the terminal may be included in a measurement report sent by the terminal to the network device, that is, the measurement report includes the third number of reference signal resource measurement results.

[0134] In the beam measurement method provided in the embodiment of the present disclosure, the measurement report sent by the terminal to the network device may further include information corresponding to the reference signal resource. For example, the information corresponding to the reference signal resource may be identification information corresponding to the reference signal resource.

[0135] In the embodiment of the present disclosure, a first number of reference signal resources are measured, and the measurement results of the first number of reference signal resources are input into the first model to obtain the measurement results of the second number of reference signal resources, so as to estimate the measurement results of the majority of reference signal resources based on the measurement results of the measured minority of reference signal resources. For example, if there are 1 to 8 beams in total, it may be necessary to measure only beams 2 and beam 5, and the measurement results of the other 6 beams can be inferred using the model. Alternatively, two beams are measured: beam 9 and beam 10, and at least one of beams 9 and beam 10 has a different direction from the directions of beams 1 to 8. For example, the beam direction of beam 9 includes the directions that can be covered by two of the beams 1 to 8, and based on the measurement results of beams 9 and beam 10, the measurement results of beams 1 to 8 are inferred using the model.

[0136] Furthermore, the terminal may send a third number of reference signal resource measurement results to the network device. The third number of reference signal resource measurement results is selected from the second number of reference signal resource measurement results in descending order of the signal strength corresponding to the measurement results. For example, if there are 1 to 8 beams in total, it may be necessary to measure only beams 2 and 5, and the measurement results of the other 6 beams can be inferred using the model. The beam measurement results finally reported are beams 3 and 4 with the strongest signal strength in the measurement results.

[0137] The signal strength corresponding to the measurement result may include L1-RSRP, L1-SINR, or layer 1 reference signal received quality (L1-Reference Signal Received Quality, L1-RSRQ), etc.

[0138] In the beam measurement method provided by the embodiment of the present disclosure, the first configuration information sent by the network device can be determined based on the first number of reference signal resources. For example, if there are 1 to 8 beams in total, it may be necessary to measure only beam 2 and beam 5, and the measurement results of the other 6 beams can be inferred using the model. The beam measurement results finally reported are beam 3 and beam 4 with the strongest signal strength in the measurement results. The terminal recommends that the few reference signal resources subsequently sent by the network device are beam 2 and beam 5. That is, the network device can configure the first configuration information based on beam 2 and beam 5, and the network device sends beam 2 and beam 5.

[0139] In the beam measurement method provided by the embodiment of the present disclosure, the terminal may determine the number of reference signal resource measurement results that need to be estimated through the model based on the configuration information sent by the network device.

[0140] Figure 3 FIG. 1 is a flow chart showing a beam measurement method according to an exemplary embodiment. Figure 3As shown, the beam measurement method is used in a terminal and includes the following steps.

[0141] In step S21, second configuration information sent by the network device is received.

[0142] The second configuration information is used to configure a second reference signal resource set, the reference signal resources in the second reference signal resource set are used for beam measurement, and the number of reference signal resources in the second reference signal resource set is a fourth number.

[0143] In the beam measurement method provided in the embodiment of the present disclosure, the terminal may determine the second number based on the fourth number. In one embodiment, the fourth number is the same as the second number, and the second number of reference signal resource measurement results respectively corresponds to each reference signal resource in the second reference signal resource set.

[0144] In the beam measurement method provided in the embodiment of the present disclosure, the terminal may recommend a small number of reference signal resources to be subsequently sent by the network device. The small number of reference signal resources may be used to determine the first reference signal resource set in the first configuration information.

[0145] Figure 4 FIG. 1 is a flow chart showing a beam measurement method according to an exemplary embodiment. Figure 4 As shown, the beam measurement method is used in a terminal and includes the following steps.

[0146] In step S31 , N reference signal resource sets are determined, wherein a reference signal resource set among the N reference signal resource sets includes a fifth number of reference signal resources.

[0147] Wherein, N is a positive integer.

[0148] In step S32, information corresponding to the reference signal resources included in each of the N reference signal resource sets is sent to the network device.

[0149] In one implementation, N reference signal resource sets are used to determine the first reference signal resource set in the first configuration information.

[0150] In one implementation, the first reference signal resource set is a subset of at least one reference signal resource set among the N reference signal resource sets.

[0151] In the embodiments of the present disclosure, the determination of the N reference signal resource sets may be based on configuration information sent by a network device. For example, the terminal determines the N reference signal resource sets based on second configuration information including a second reference signal resource set. In one embodiment, the N reference signal resource sets are subsets of the second reference signal resource set.

[0152] In one example, a terminal measures reference signals in a second set of reference signal resources and trains a first model for beam management. The first model receives beam measurement results for a fifth number of reference signal resources as input, and outputs measurement results for a fourth number of reference signal resources as output. The fifth number is smaller than the fourth number, and the fifth number of reference signal resources is the fifth number of reference signal resources in the second set of reference signal resources.

[0153] In the beam measurement method provided by the embodiment of the present disclosure, the fifth number of reference signal resources included in the N reference signal resource sets can be understood as a small number of reference signal resources recommended by the terminal for subsequent transmission by the network device.

[0154] In the beam measurement method provided by the embodiment of the present disclosure, the fifth number of reference signal resources can be determined based on the first model.

[0155] In one embodiment, the fifth number is the number of reference signal resources included in the reference signal resource set with the smallest number of reference signal resources among the N reference signal resource sets. The accuracy of the second number of reference signal resource measurement results obtained by inputting the fifth number of reference signal resource measurement results into the first model is greater than or equal to a first accuracy threshold.

[0156] In the beam measurement method provided in an embodiment of the present disclosure, a terminal determines a fifth number of reference signal resources using a first model. When the fifth number of reference signal resources is used as input to the first model, the accuracy of the output measurement result of the second number of reference signal resources is greater than a first accuracy threshold.

[0157] In one embodiment, the accuracy of the measurement results of the second number of reference signal resources output by the first model is determined by the difference between the estimated measurement results and the actual measurement results, that is, the difference between the estimated measurement results of the second number of reference signal resources output by the first model and the actual measurement results of the second number of reference signal resources. The calculation method can be optionally as follows: taking the difference between the estimated measurement results of the second number of reference signal resources output by the first model and the actual measurement results of the second number of reference signal resources, then squaring the differences, and then averaging the squares of the differences to obtain an accuracy evaluation value as the accuracy of the measurement results of the second number of reference signal resources. Of course, the embodiment of the present disclosure does not limit the calculation method of the accuracy of the measurement results of the second number of reference signal resources output by the first model, and may include other calculation methods in addition to the above-mentioned calculation methods.

[0158] In the beam measurement method provided in the embodiment of the present disclosure, the fifth number of reference signal resources is determined using at least one of the following methods:

[0159] Method 1: Determine based on the accuracy of the reference signal resource measurement result output by the first model.

[0160] Method 2: Determined based on the configuration information sent by the network device.

[0161] Method three: determined based on the provisions of the agreement.

[0162] It is understood that there are multiple implementations of determining the fifth number of reference signal resources in the embodiments of the present disclosure based on the above-mentioned approach. In one example, the fifth number can be determined based on configuration information or protocol provisions, and further determined based on the first model.

[0163] In one example, for example, the value of the fifth number is specified by a network device configuration or protocol, then the terminal knows the value of the fifth number, and then arbitrarily selects a fifth number of reference signal resources from the second number of reference signal resources, and inputs the measurement results of the arbitrary fifth number of reference signal resources into the first model. If the accuracy of the output measurement results of the second number of reference signal resources is greater than the first accuracy threshold, the identity of the fifth number of reference signal resources is determined.

[0164] In another example, for example, if the value of the fifth number is determined by the terminal, the terminal may first arbitrarily select measurement results of a fifth number of reference signal resources starting with the fifth number = 1, input the results into the first model, and determine whether the accuracy of the output measurement results of the second number of reference signal resources is greater than the first accuracy threshold. If the accuracy of the measurement results of the second number of reference signal resources is greater than the first accuracy threshold, the identifiers of the fifth number of reference signal resources are determined.

[0165] In another example, the fifth number of reference signal resources is provided based on configuration information of the network device, for example, the network device provides identification information of the fifth number of reference signal resources.

[0166] In the beam measurement method provided in the embodiments of the present disclosure, the network device may transmit the second configuration information once and then periodically transmit the reference signal resources in the second reference signal resource set. Alternatively, the network device may periodically or aperiodically transmit the reference signal resources in the second reference signal resource set according to a configured time.

[0167] In one embodiment, in the beam measurement method provided by an embodiment of the present disclosure, the terminal receives reference signal resources in a second reference signal resource set sent by a network device, and determines N reference signal resource sets based on the reference signal resources in the received second reference signal resource set.

[0168] Among them, for the first configuration information, if the reference signal resources in the N reference signal resource sets are changed from the previous ones, the terminal needs to report it, and the network device needs to send the first configuration information to update the first reference signal resource set.

[0169] In one implementation, the terminal may receive reference signal resources in the first reference signal resource set periodically sent by the network device within a sending period of the second reference signal resource set.

[0170] In which, the first reference signal resource set may be different in different periods of the second reference signal resource set.

[0171] The first model involved in the embodiment of the present disclosure may be an artificial intelligence (AI) model. The first model may be used for beam management.

[0172] In one implementation, the first model involved in the embodiments of the present disclosure may be pre-trained.

[0173] In one example, in the beam measurement method provided by an embodiment of the present disclosure, the fourth number of reference signal resources included in the second reference signal resource set can also be used to determine the first model. The first model is pre-trained based on the fourth number of reference signal resources included in the second reference signal resource set.

[0174] Figure 5 is a flow chart of a method for determining a first model according to an exemplary embodiment. Figure 5 As shown, the method for determining the first model includes the following steps.

[0175] In step S41, beam measurement is performed on a fourth number of reference signal resources in the second reference signal resource set.

[0176] In step S42, a first model is obtained based on the measured results of the fourth number of reference signal resources.

[0177] In another embodiment, the terminal may obtain the first model from another device. In one example, the first model is obtained from at least one of the following devices: a network device; a cloud device; and another terminal device different from the terminal device.

[0178] In the beam measurement method provided by the embodiment of the present disclosure, the first reference signal resource set and the second reference signal resource set may include a first stage and a second stage.

[0179] Figure 6 FIG2 shows a schematic diagram of a terminal receiving a first reference signal resource set and a second reference signal resource set in an exemplary embodiment of the present disclosure. Figure 6 As shown, the process of a terminal receiving the first reference signal resource set and the second reference signal resource set includes a first phase and a second phase. The first phase is used for the terminal to train and obtain a first model for beam management. The duration of the first phase can have various possibilities, including being very long, relatively short, or almost zero (for example, the terminal directly downloads the first model from a network device, the cloud, or another terminal).

[0180] Figure 6 In the first stage shown, the network device mainly sends the reference signal resources in the second reference signal resource set, that is, the network device sends more reference signal resources for beam measurement, and the specific sending period is not limited, such as 2 slots, 4 slots, 8 slots or more, but is just a schematic.

[0181] Figure 6 In the second stage shown, the second stage may include K transmission opportunities for transmitting reference signal resources, with only the first transmission opportunity transmitting the reference signal resources in the second reference signal resource set, and the subsequent transmission opportunities transmitting the reference signal resources in the first reference signal resource set. Of course, it is also possible that the first and second transmission opportunities among the K transmission opportunities transmit the reference signal resources in the second reference signal resource set, and the subsequent transmissions transmit the reference signal resources in the first reference signal resource set. The first z transmission opportunities among the K transmission opportunities transmit the reference signal resources in the second reference signal resource set. Wherein, z is an integer greater than or equal to 1. The value of z mainly depends on the terminal's determination of X reference signal resources based on the measurement results of the reference signal resources in the second reference signal resource set in the first transmission opportunity, the feedback of X reference signal resource identifiers, and the total time for the network device to resend the first configuration information. Wherein, the X reference signal resources are used by the network device to configure the first reference signal resource set.

[0182] Figure 7 FIG2 shows a schematic diagram of a terminal receiving a first reference signal resource set and a second reference signal resource set in an exemplary embodiment of the present disclosure. Figure 7 As shown, after the first model is obtained, with K transmission opportunities as a cycle, within a cycle, the first transmission opportunity or the first z transmission times transmit the reference signal resources in the second reference signal resource set, and the subsequent transmissions all transmit the reference signal resources in the first reference signal resource set, so as to reduce signaling overhead and reduce terminal measurement complexity. Figure 7As shown, after periodically receiving the first reference signal resource set for a period of time, the second reference signal resource set can be re-received to facilitate the update of the terminal's first model and / or the update of the first reference signal resource set. That is, in a subsequent period, the terminal can receive the second reference signal resource set again at the z transmission times preceding the K transmission times, and use the reference signal resources in the second reference signal resource set to re-determine X reference signal resources for the network device to update the first reference signal resource set. There are multiple methods for triggering the reporting of the X reference signal resources: triggering the reporting every period, or triggering the reporting only when the determined X reference signal resources are different from the last determined ones. This is not limited here.

[0183] To reduce signaling overhead for reference signal resources used for beam management, the beam measurement method provided in the present disclosure proposes alternating transmission of two differently configured reference signal resource sets. To optimize the configuration of a smaller number of reference signal resources in a first reference signal resource set, a terminal determines which reference signal resources to select as reference signal resources in the first reference signal resource set based on a first beam management model and reports these to a network device. This reduces signaling overhead while ensuring the accuracy of beam measurement results.

[0184] Figure 8 FIG2 shows a flow chart of a beam measurement method in an exemplary embodiment of the present disclosure. Figure 8 As shown, the beam measurement method is applied to a network device and includes the following steps:

[0185] In step S51, first configuration information is sent.

[0186] The first configuration information is used to configure a first reference signal resource set. The reference signal resources in the first reference signal resource set are used for beam measurement. The number of reference signal resources in the first reference signal resource set is a first number.

[0187] In the beam measurement method provided by the embodiment of the present disclosure, the reference signal resources in the first number of reference signal resources may be included in the second number of reference signal resources, or may not be included in the second number of reference signal resources.

[0188] In step S52, a measurement report sent by the terminal is received, where the measurement report includes a third number of reference signal resource measurement results, and the third number of reference signal resource measurement results is a subset of the second number of reference signal resource measurement results.

[0189] The second number of reference signal resource measurement results is obtained by the terminal performing beam measurement on the first number of reference signal resources respectively, and inputting the measured first number of reference signal resource measurement results into the first model, and the second number is greater than or equal to the first number.

[0190] In one implementation, the first model is obtained by the terminal performing beam measurement on a fourth number of reference signal resources in the second reference signal resource set, and based on the measurement results of the fourth number of reference signal resources obtained by measurement.

[0191] In one embodiment, the first model is obtained by the terminal from other devices; the other devices include one or a combination of the following: network devices, cloud devices, and other terminals different from the terminal.

[0192] In one implementation, the third number of reference signal resource measurement results are selected from the second number of reference signal resource measurement results in descending order of signal strength corresponding to the measurement results.

[0193] Figure 9 FIG. 1 is a flow chart showing a beam measurement method according to an exemplary embodiment of the present disclosure. Figure 9 As shown, the beam measurement method is applied to a network device and includes the following steps:

[0194] In step S61, second configuration information is sent, where the second configuration information is used to configure a second reference signal resource set. Reference signal resources in the second reference signal resource set are used for beam measurement, and the number of reference signal resources in the second reference signal resource set is a fourth number.

[0195] Figure 10 FIG2 shows a flow chart of a beam measurement method according to an exemplary embodiment of the present disclosure. Figure 10 As shown, the beam measurement method is applied to a network device and includes the following steps:

[0196] In step S71, information corresponding to reference signal resources included in each of N reference signal resource sets sent by a terminal is received, wherein the reference signal resource set in the N reference signal resource sets includes a fifth number of reference signal resources.

[0197] Wherein, N is a positive integer.

[0198] In one implementation, N reference signal resource sets are used to determine the first reference signal resource set in the first configuration information.

[0199] In one implementation, the first reference signal resource set is a subset of at least one reference signal resource set among the N reference signal resource sets.

[0200] In one embodiment, the fifth number is the number of reference signal resources included in the reference signal resource set with the smallest number of reference signal resources among the N reference signal resource sets. The fifth number satisfies the requirement that the accuracy of the second number of reference signal resource measurement results obtained by inputting the fifth number of reference signal resource measurement results into the first model is greater than or equal to a first accuracy threshold.

[0201] The fifth number of reference signal resources is provided based on configuration information of the network device, for example, the network device provides identification information of the fifth number of reference signal resources.

[0202] In one implementation, the fifth number of reference signal resources is determined using at least one of the following methods:

[0203] determining an accuracy of a reference signal resource measurement result outputted by the first model;

[0204] Determined based on configuration information sent by the network device;

[0205] Determined based on the provisions of the agreement.

[0206] In one implementation, the N reference signal resource sets are subsets of the second reference signal resource set.

[0207] In one implementation, the fourth number is the same as the second number, and the second number of reference signal resource measurement results respectively correspond to each reference signal resource in the second reference signal resource set.

[0208] In one embodiment, in the beam measurement method provided in the embodiments of the present disclosure, the network device may transmit the second configuration information once, and then periodically transmit the second reference signal resource set. That is, the network device periodically transmits the reference signal resources in the second reference signal resource set. Alternatively, the network device may periodically or aperiodically transmit the reference signal resources in the second reference signal resource set according to a configured time.

[0209] Among them, for the first configuration information, if the reference signal resources in the N reference signal resource sets are changed from the previous ones, the terminal needs to report it, and the network device needs to send the first configuration information to update the first reference signal resource set.

[0210] In one implementation, the network device may periodically transmit the reference signal resources in the first reference signal resource set within a transmission period of the second reference signal resource set.

[0211] In which, the first reference signal resource set may be different in different periods of the second reference signal resource set.

[0212] It can be understood that the implementation process of the network device performing beam measurement in the embodiment of the present disclosure can be similar to the implementation process of the terminal performing beam measurement. Therefore, for the parts that are not described in detail in the network device performing beam measurement method, reference can be made to the terminal performing beam measurement method, and no further details will be given here.

[0213] The embodiments of the present disclosure will now illustrate the beam measurement method involved in the above embodiments in combination with practical applications.

[0214] In the following embodiments of the present disclosure, the first quantity is represented by L, the second quantity and the fourth quantity are the same and are represented by M, the third quantity is represented by Y, and the fifth quantity is represented by X.

[0215] The terminal receives second configuration information sent by the network device, where the second configuration information is used to configure a second reference signal resource set, where reference signal resources in the second reference signal resource set are used for beam measurement, and the second reference signal resource set includes M reference signal resources.

[0216] The terminal determines X reference signal resources and feeds back identifiers of the X reference signal resources to the network device.

[0217] The X reference signal resources are used by the network device to send first configuration information, the first configuration information is used to configure a first reference signal resource set, and the reference signal resources in the first reference signal resource set are also used for beam measurement. The first reference signal resource set includes L reference signal resources, where L is less than M.

[0218] Typically, the L reference signal resources in the first reference signal resource set are the same as the X reference signal resources.

[0219] In the embodiment of the present disclosure, the terminal determines X reference signal resources, including the following methods:

[0220] Method 1: The terminal measures reference signals in the second reference signal resource set and trains a beam management model. The beam management model receives as input the beam measurement results of X reference signal resources and outputs the measurement results of M reference signal resources. Where X is less than M, and the X reference signal resources are X reference signal resources in the second reference signal resource set.

[0221] Method 2: The terminal determines X reference signal resources through the AI ​​model, where these X reference signal resources are used as input to the beam management model, and the accuracy of the output beam measurement results of the M reference signal resources is greater than the first accuracy threshold.

[0222] The accuracy may be calculated by subtracting beam measurement results of the M reference signal resources output by the beam management model from actual measurement results of the M reference signal resources, squaring the differences, and averaging the squared differences to obtain an accuracy evaluation value, which is then compared with a first threshold.

[0223] How to determine X reference signal resources:

[0224] The value of X may be determined by a network device configuration, a protocol specification, or by the terminal entirely based on a comparison of accuracy with a first threshold.

[0225] For example, if the value of X is specified by a network device configuration or a protocol, then the terminal knows the value of X. Then, X reference signal resources are randomly selected from the M reference signal resources, and measurement results of the random X reference signal resources are input into the beam management model. If the accuracy of the output measurement results of the M reference signal resources is greater than a first threshold, the identities of the X reference signal resources are determined.

[0226] For example, if the value of X is determined by the terminal, the terminal may start with X=1 and arbitrarily select measurement results of X reference signal resources to input into the beam management model. The terminal then determines whether the accuracy of the output measurement results of the M reference signal resources is greater than a first threshold. If so, the terminal determines the identities of the X reference signal resources.

[0227] The terminal receives first configuration information sent by the network device, measures reference signal resources in a first reference signal resource set in the first configuration information, inputs measurement results of the measured reference signal resources into the model, obtains measurement results of M reference signal resources, and feeds back identifiers and measurement results of the Y strongest reference signal resources.

[0228] Subsequently, the reference signal resources in the second reference signal resource set are further sent periodically for the terminal to update X reference signal resources, that is, for the network device to update the reference signal resources in the first reference signal resource set.

[0229] It is further understood that the beam measurement method provided in the embodiments of the present disclosure is applicable to the interaction between a terminal and a network device to implement beam measurement. During the interaction between the terminal and the network device to implement beam measurement, the terminal has the terminal functions involved in the above embodiments, and the network device has the network device functions involved in the above embodiments.
