Description

Beam measurement method, device and storage medium Technical Field

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

[0002] Millimeter-wave and terahertz communications have become potential key technologies for 6G. High-frequency electromagnetic waves experience significant propagation losses, necessitating the use of massive multiple-in-multiple-out (MIMO) beamforming to address coverage issues. To mitigate the severe path losses associated with high-frequency millimeter-wave and terahertz communications, narrow beams are required for data transmission. These narrow beams place high demands on beam scanning speed and beam tracking timeliness.

[0003] In Massive MIMO and Reconfigurable Intelligent Surface (RIS) array scenarios, the far-field assumption no longer applies. Electromagnetic wave propagation can no longer be modeled as a far-field plane wave that depends solely on angle, but rather as a near-field spherical wave that depends on "angle-distance." To complete beam scanning of the coverage area from both the "distance" and "angle" dimensions, a larger number of beams is required, increasing the complexity of beam measurement and reporting by the terminal. Reducing the complexity of terminal measurement and reporting is a challenge that needs to be addressed.

[0045] Exemplary embodiments are described in detail herein, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numerals in different drawings represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure.

[0046] The beam measurement method of the embodiment of the present disclosure can be applied to the wireless communication system shown in Figure 1. Referring to Figure 1, the wireless communication system includes a network device and a terminal. The terminal is connected to the network device via wireless resources and performs data transmission.

[0047] It should be understood that the wireless communication system shown in Figure 1 is for illustrative purposes only, and the wireless communication system may also include other network devices, such as core network devices, wireless relay devices, and wireless backhaul devices, which are not shown in Figure 1. The embodiments of the present disclosure do not limit the number of network devices and terminals included in the wireless communication system.

[0048] 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), and 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. 5G network 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.

[0049] Furthermore, the network devices involved in the present disclosure may also be referred to as wireless access network devices. The wireless access network device may be: a base station, an evolved node B (base station), a home base station, an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP) or a transmission and reception point (TRP), etc. It may also be a gNB in ​​an NR system, or it may also be a component or part of a base station. It should be understood that in the embodiments of the present disclosure, the specific technology and specific device form adopted by the network device are not limited. In the present disclosure, the network device can provide communication coverage for a specific geographical area and can communicate with terminals located in the coverage area (cell). In addition, when it is a vehicle-to-everything (V2X) communication system, the network device may also be a vehicle-mounted device.

[0050] 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), customer premises equipment (Customer Premise Equipment, CPE), pocket computers (Pocket Personal Computers, PPCs), handheld computers, personal digital assistants (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.

[0051] Among related technologies, millimeter wave communication has become a key technology for 5G NR. As low-frequency wireless spectrum resources are exhausted, the development and utilization of high-frequency millimeter wave and even terahertz communication technologies have become an inevitable trend.

[0052] Regarding spectrum allocation for terahertz wireless communications, the International Telecommunication Union (ITU) has completed frequency allocations for various services within the 100-275 GHz frequency range. This includes 97.2 GHz of globally designated spectrum for land mobile and fixed services. At the 2019 World Radiocommunication Conference (WRC-19), based on WRC-15 Resolution 767 and the findings of WRC-19 Agenda 1.15, the conference added four globally designated mobile service bands within the 275-450 GHz frequency range: 275-296 GHz, 306-313 GHz, 318-333 GHz, and 356-450 GHz. This adds a total of 137 GHz of spectrum bandwidth.

[0053] In 2019, China's International Mobile Telecom System (IMT) IMT-2030 (6G) Promotion Group's Wireless Technology Working Group established a terahertz communication task force, identifying terahertz communication as an important candidate technology for future 6G communications. The task force will study and discuss key technologies, application visions, and standardization of terahertz communications, laying the foundation for research and industry consensus on the inclusion of terahertz communications in IMT communication technology standards.

[0054] Millimeter-wave and terahertz communications have become potential key technologies for 6G. High-frequency electromagnetic waves experience significant propagation losses, necessitating the use of Massive MIMO beamforming to address coverage issues. To mitigate the severe path losses associated with high-frequency millimeter-wave and terahertz communications, narrow beams are required for data transmission. These narrow beams place high demands on beam scanning speed and beam tracking timeliness.

[0055] In Massive MIMO and RIS array scenarios, the far-field assumption no longer applies. Electromagnetic wave propagation can no longer be modeled as a far-field plane wave that depends solely on angle. Instead, it should be modeled as a near-field spherical wave that depends on the "angle-distance" relationship. To complete beam scanning of the coverage area from both the "distance" and "angle" dimensions, a large number of beams are required, which increases the complexity of beam measurement and reporting by the terminal. Reducing the complexity of UE measurement and reporting is a challenge that needs to be addressed.

[0056] In view of this, an embodiment of the present disclosure provides a beam measurement method, in which the terminal performs beam measurement based on a configured beam group for beam measurement, or a candidate beam group corresponding to the beam group. This can reduce the complexity of the terminal performing beam measurement and improve the efficiency of beam measurement when the beam needs to be used to complete beam scanning of the coverage area.

[0057] The beam measurement method provided by the embodiment of the present disclosure groups the beams supported by the network device through the network device, and configures a candidate beam group for each beam group. The terminal receives the beam group and candidate beam group information. When the terminal needs to use the beam to complete the beam scanning of the coverage area, or when the terminal measures and reports the beam sent by the network device to assist the network device in beam scanning, the reference signal corresponding to the beam in the beam group is measured. Or when the beam group to be measured does not meet the conditions, the reference signal corresponding to the beam in the candidate beam group corresponding to the beam group to be measured is measured, and there is no need for the terminal to select the beam for measurement by itself, thereby reducing the complexity of the beam measurement performed by the terminal and improving the efficiency of the beam measurement.

[0058] In one embodiment, in the beam measurement method provided by the embodiment of the present disclosure, for the convenience of description, the beam group configured by the network device for beam measurement is called the first beam group, and the candidate beam group corresponding to the first beam group is called the second beam group.

[0059] In a beam measurement method provided by an embodiment of the present disclosure, a network device configures a first beam group for beam measurement and a second beam group corresponding to the first beam group. The second beam group is a candidate beam group for the first beam group. The first beam group and the second beam group have a corresponding relationship.

[0060] In the embodiment of the present disclosure, the number of the first beam groups may be one or more, and the number of the second beam groups may also be one or more. There is a corresponding relationship between each first beam group and each second beam group.

[0061] It will be understood that in the embodiments of the present disclosure, the first beam group and the second beam group are beam groups configured by the network device for beam measurement. For ease of description, in the embodiments of the present disclosure, the beams used for beam measurement, including the first beam group and the second beam group, are referred to as a beam measurement set.

[0062] It should be noted that the beam in the embodiments of the present disclosure may represent a beam or a reference signal corresponding to a beam, and sometimes no distinction is made.

[0063] FIG2 is a flowchart showing a beam measurement method according to an exemplary embodiment. The beam measurement method is used in a terminal. As shown in FIG2 , the method includes the following steps.

[0064] In step S21, beam measurement information configured by a network device is received, where the beam measurement information is used to configure a beam measurement set.

[0065] In the embodiment of the present disclosure, the beam measurement set includes a first beam group for performing beam measurement and a second beam group corresponding to the first beam group, wherein the second beam group is a candidate beam group of the first beam group.

[0066] In step S22 , beam measurement is performed based on the beam measurement set.

[0067] In an embodiment of the present disclosure, a terminal may receive beam measurement information configured by a network device. The beam measurement information may be used to indicate a first beam group for the terminal to perform beam measurement, and a second beam group corresponding to the first beam group. In one example, the beam measurement information may indicate that the terminal performs beam measurement on beam group A1, beam group A2, and so on. N The first beam group, and the beam group B1, beam group B2... beam group B NThe second beam group is a candidate beam group of the first beam group, and N is a positive integer. The second beam group is a candidate beam group of the first beam group, and the second beam group corresponds to the first beam group.

[0068] Furthermore, in an embodiment of the present disclosure, the beam measurement information can be used to configure a beam measurement set. The beam measurement set includes the beams indicated by the beam measurement information, and the beams in the beam measurement set include a first beam group and a second beam group corresponding to the first beam group. In one example, the beam measurement set may include a first beam group set, which includes beam group A1, beam group A2, ..., beam group A. N , and the beam measurement set may further include a second beam group set, the second beam group set including beam group B1, beam group B2... beam group B N The second beam group is a candidate beam group of the first beam group. It can also be understood that the first beam group set is the measurement set and the second beam group set is the extended measurement set.

[0069] In embodiments of the present disclosure, beam measurement can be performed based on a beam measurement set. As previously described, the beam measurement set includes a first beam group configured by a network device and a second beam group corresponding to the first beam group, where the second beam group is a candidate beam group for the first beam group. Beam measurement can be performed based on either the first beam group or the second beam group in the beam measurement set.

[0070] By adopting the technical solution of the embodiment of the present disclosure, the terminal performs beam measurement based on the configured beam group for beam measurement, or the candidate beam group corresponding to the beam group. When the beam needs to be used to complete the beam scanning of the coverage area, the complexity of the terminal performing beam measurement can be reduced and the efficiency of the beam measurement can be improved.

[0071] In the embodiments of the present disclosure, beam measurement information may include beam index information or reference signal information corresponding to the beams included in the first beam group and the second beam group. In one example, the beam measurement information may include group index information for the first beam group and the second beam group, as well as beam index information for the beams included in the first beam group and the second beam group. In another example, the beam measurement information may include reference signal information corresponding to the beams included in the first beam group and the second beam group.

[0072] In the embodiment of the present disclosure, the beam measurement set may include one or more first beam groups and one or more second beam groups, wherein each first beam group in the one or more first beam groups has a corresponding relationship with each second beam group in the one or more second beam groups. Still assuming that the beam measurement set includes the first beam group set, the first beam group set includes beam group A1, beam group A2, ..., beam group A N, and the beam measurement set may further include a second beam group set, the second beam group set including beam group B1, beam group B2... beam group B N For example, beam group A1 and beam group B1 may have a corresponding relationship, that is, beam group B1 is a candidate beam group of beam group A1; beam group A2 and beam group B2 may have a corresponding relationship, that is, beam group B2 is a candidate beam group of beam group A2, and so on.

[0073] In embodiments of the present disclosure, the second beam group can be used for beam measurement when the first beam group does not meet measurement requirements. In one example, when the first beam group does not meet the measurement requirements, the terminal directly performs beam measurement on the reference signal corresponding to the beam in the second beam group corresponding to the first beam group, without having to re-acquire beam measurement change information from the network device and re-determine the beam group for beam measurement based on the beam measurement change information. This improves beam measurement efficiency and reduces beam measurement complexity.

[0074] In the disclosed embodiments, to ensure that, when the first beam group fails to meet measurement requirements, the measurement results based on the reference signals corresponding to the beams in the second beam group can also provide a reference for the network device to determine beam indication information, the second beam group and the first beam group can be spatially adjacent. In other words, a beam group spatially adjacent to the first beam group can be selected as a candidate second beam group.

[0075] Spatially adjacent may mean that the coverage areas of different beams, as determined by the distances between the beams and the Transmission and Receiving Point (TRP) and the beam angles, are spatially adjacent. In one example, the coverage area of ​​a second beam group, as determined by the distance between the second beam group and the TRP and the beam angle of the second beam group, may be spatially adjacent to the coverage area of ​​a first beam group, as determined by the distance between the first beam group and the TRP and the beam angle of the first beam group.

[0076] In the disclosed embodiments, a first beam group may include one or more beams, and different first beam groups may include the same beam. In other words, the beams included in different first beam groups may overlap, meaning that the same beam may appear in two or more first beam groups.

[0077] In the disclosed embodiments, a second beam group may include one or more beams, and different second beam groups may include the same beam. In other words, the beams included in different second beam groups may overlap, meaning that the same beam may appear in two or more second beam groups.

[0078] By adopting the technical solution of the embodiment of the present disclosure, the terminal performs beam measurement based on the configured beam group for beam measurement, or the candidate beam group corresponding to the beam group. When the beam group to be measured does not meet the conditions, the reference signal corresponding to the beam in the candidate beam group corresponding to the beam group to be measured is measured. The terminal does not need to select the beam for measurement by itself, thereby reducing the complexity of the terminal's beam measurement and improving the efficiency of the beam measurement.

[0079] FIG3 is a flow chart showing a beam measurement method according to an exemplary embodiment. As shown in FIG3 , the method includes the following steps.

[0080] In step S31, beam measurement information configured by a network device is received, where the beam measurement information is used to configure a beam measurement set. The beam measurement set includes a first beam group for performing beam measurement and a second beam group corresponding to the first beam group.

[0081] The second beam group is a candidate beam group of the first beam group.

[0082] In step S32, a beam quality threshold sent by a network device is received.

[0083] In step S33, the beam-corresponding reference signals in the first beam group are measured.

[0084] In step S34, in response to determining that the beam quality measured based on the reference signals corresponding to the beams in the first beam group is less than the beam quality threshold, the reference signals corresponding to the beams in the second beam group are measured to obtain a measurement result.

[0085] In an embodiment of the present disclosure, a terminal may receive beam measurement information configured by a network device. The beam measurement information may be used to indicate a first beam group for the terminal to perform beam measurement, and a second beam group corresponding to the first beam group. In one example, the beam measurement information may indicate that the terminal performs beam measurement on beam group A1, beam group A2, and so on. N The first beam group, and the beam group B1, beam group B2... beam group B N The second beam group is a candidate beam group of the first beam group, and N is a positive integer. The second beam group is a candidate beam group of the first beam group, and the second beam group corresponds to the first beam group.

[0086] Furthermore, in an embodiment of the present disclosure, the beam measurement information can be used to configure a beam measurement set. The beam measurement set includes the beams indicated by the beam measurement information, and the beams in the beam measurement set include a first beam group and a second beam group corresponding to the first beam group. In one example, the beam measurement set may include a first beam group set, which includes beam group A1, beam group A2, ..., beam group A. N, and the beam measurement set may further include a second beam group set, the second beam group set including beam group B1, beam group B2... beam group B N The second beam group is a candidate beam group of the first beam group. It can also be understood that the first beam group set is the measurement set and the second beam group set is the extended measurement set.

[0087] Furthermore, in an embodiment of the present disclosure, the terminal may also receive a beam quality threshold sent by a network device and measure reference signals corresponding to beams in a first beam group. In response to determining that the beam quality measured based on the reference signals corresponding to beams in the first beam group is less than the beam quality threshold, the terminal may measure the reference signals corresponding to beams in a second beam group to obtain a measurement result. In one example, the terminal may perform beam quality assessment on the beams in the first beam group by measuring based on the reference signals corresponding to beams in the first beam group. If the beam quality assessment result for the beams in the first beam group does not meet the beam quality threshold, that is, if the beam quality measured based on the reference signals corresponding to beams in the first beam group is less than the beam quality threshold, the terminal determines that the beam does not meet the quality requirement. In this case, the terminal may continue to perform beam quality assessment on the beams in the second beam group by measuring based on the reference signals corresponding to beams in the second beam group corresponding to the first beam group. When the result of the quality evaluation of the beam in the second beam group meets the beam quality threshold, that is, when the beam quality measured based on the reference signal corresponding to the beam in the second beam group is greater than or equal to the beam quality threshold, the measurement result of the reference signal corresponding to the beam in the second beam group will be reported to the network device.

[0088] In the disclosed embodiments, a beam quality assessment result may be determined using at least one of the following methods: whether a measured value of a smoothed beam-corresponding reference signal within a period of time is above or below a first preset threshold, the number of times the measured value of the smoothed beam-corresponding reference signal within a period of time is above or below a second preset threshold, or the proportion of times the measured value of the smoothed beam-corresponding reference signal within a period of time is above or below a third preset threshold. The values ​​of the first, second, and third preset thresholds may be determined based on actual needs, and the first, second, and third preset thresholds may be the same or different.

[0089] FIG4 is a flow chart of a beam measurement method according to an exemplary embodiment, wherein steps S41-S43 are the same as steps S31-S33 in the embodiment shown in FIG3 and are not described in detail here. As shown in FIG4 , the method further includes the following steps.

[0090] In step S44, in response to determining that the beam quality measured based on the reference signal corresponding to the beam in the first beam group is greater than or equal to the beam quality threshold, a measurement result of measuring the reference signal corresponding to the beam in the first beam group is obtained.

[0091] In an embodiment of the present disclosure, a terminal may receive a beam quality threshold sent by a network device and measure reference signals corresponding to beams in a first beam group. In response to determining that the beam quality measured based on the reference signals corresponding to the beams in the first beam group is greater than or equal to the beam quality threshold, a measurement result of the reference signals corresponding to the beams in the first beam group is obtained. In one example, the terminal may perform beam quality assessment on the beams in the first beam group by measuring the reference signals corresponding to the beams in the first beam group. If the beam quality assessment result of the beams in the first beam group meets the beam quality threshold, that is, if the beam quality measured based on the reference signals corresponding to the beams in the first beam group is greater than or equal to the beam quality threshold, the beams in the first beam group are determined to meet the quality requirement. In this case, there is no need to further perform beam quality assessment on the beams in the candidate beam group of the first beam group, that is, the beams in the second beam group corresponding to the first beam group. The measurement result of the reference signals corresponding to the beams in the first beam group may be directly reported to the network device.

[0092] Furthermore, in an embodiment of the present disclosure, in response to determining that beam qualities measured based on reference signals corresponding to beams in a first beam group and a corresponding second beam group in a beam measurement set are both less than a beam quality threshold, reference signals corresponding to beams in other first beam groups in the beam measurement set that are different from the first beam group are received and measured. The other first beam groups are determined based on beam measurement change information sent by a network device, or based on measurement results of beam measurements performed by a terminal on the other first beam groups.

[0093] It is understandable that when the beam qualities measured based on the beam-corresponding reference signals in the first beam group and the corresponding second beam group in the beam measurement set are both less than the beam quality threshold, it can be considered that the beams in the first beam group and the corresponding second beam group in the beam measurement set do not meet the quality requirements. In this case, the terminal needs to re-determine a new first beam group and measure the beam-corresponding reference signals included in the new first beam group. The re-determined new first beam group can be another first beam group in the beam measurement set that is different from the above-mentioned first beam group.

[0094] In an embodiment of the present disclosure, on the one hand, the terminal can receive beam measurement change information from the network device, and the beam measurement change information can be used to indicate a new first beam group. The terminal measures the beam corresponding reference signal included in the new first beam group or its corresponding second beam group, and reports the measurement result to the network device for reference by the network device. The network device determines the beam used for signal reception or transmission based on the measurement result reported by the terminal and other reference factors, and indicates the determined beam through the beam indication information. In an embodiment of the present disclosure, the terminal can also determine other first beam groups based on the measurement result of the terminal performing beam measurement on other first beam groups.

[0095] In one example, the beam measurement information may indicate that the terminal performs beam measurement on multiple first beam groups including beam group A1, beam group A2, beam group A3, etc., and multiple second beam groups including beam group B1, beam group B2, beam group B3, etc., wherein the second beam group is a candidate beam group of the first beam group, and the second beam group corresponds to the first beam group. When the terminal performs beam measurement on the first beam group A1, beam group A2, beam group A3, etc., i and the first beam group A i The corresponding second beam group B i When the beam quality measured by the reference signal of the medium beam is less than the beam quality threshold, the terminal can j The beam corresponding reference signal included in is measured. j Determined by the beam measurement change information received by the terminal from the network device.

[0096] Furthermore, in the embodiment of the present disclosure, the terminal sends a signal to the first beam group A. j The beam corresponding reference signal included in is measured, and the first beam group A j When the beam quality measured by the reference signal corresponding to the medium beam is less than the beam quality threshold, the second beam group B is further j The beam corresponding reference signal included in is measured.

[0097] On the other hand, the terminal can also remove the first beam group A based on the terminal pair i With the second beam group B i The measurement results of other beam groups other than the first beam group A are used to determine the first beam group A. j , for the first beam group A j The beam corresponding reference signal included in is measured, and the first beam group A j When the beam quality measured by the reference signal corresponding to the medium beam is less than the beam quality threshold, the second beam group B is further j The beam corresponding reference signal included in is measured.

[0098] Wherein, i and j are different positive integers.

[0099] FIG5 is a flow chart of a beam measurement method according to an exemplary embodiment, wherein steps S51-S52 are the same as steps S21-S22 in the embodiment shown in FIG2 and are not described in detail here. As shown in FIG5 , the method further includes the following steps.

[0100] In step S53, the measurement result is reported to the network device.

[0101] The measurement result includes beam index information corresponding to the measured beam and beam quality information corresponding to the measured beam. Furthermore, the beam index information includes the beam index, or the index of the reference signal corresponding to the beam.

[0102] In the disclosed embodiment, after determining the measurement result, the terminal may report the measurement result to the network device. It is understood that the measurement result may be a measurement result of the reference signal corresponding to the beam in the first beam group, or a measurement result of the reference signal corresponding to the beam in the second beam group.

[0103] Furthermore, in an embodiment of the present disclosure, the measurement result may include beam index information corresponding to the measured beam and beam quality information corresponding to the measured beam.

[0104] FIG6 is a flow chart of a beam measurement method according to an exemplary embodiment, wherein steps S61-S63 are the same as steps S51-S53 in the embodiment shown in FIG5 and are not described in detail here. As shown in FIG6 , the method further includes the following steps.

[0105] In step S64, beam indication information is received.

[0106] The beam indication information is used to indicate the beam determined by the network device for signal reception or transmission.

[0107] In an embodiment of the present disclosure, the terminal may also receive beam indication information from a network device, where the beam indication information is used to indicate the beam determined by the network device for signal reception or transmission. The beam indication information may include at least one of the following: a beam group index, a beam index within a beam group. Furthermore, since the Transmission Configuration Index (TCI) state is associated with a specific reference signal, when the terminal receives a TCI indication, corresponding to downlink reception, during a specific time period, the terminal may consider that the network device uses the beam used by the reference signal associated with the TCI state for transmission; corresponding to uplink transmission, during a specific time period, the terminal uses the receive spatial filter corresponding to the reference signal associated with the TCI state for transmission. Therefore, the beam of the reference signal associated with the TCI state may also be represented by a TCI state identifier (Identity Document, ID). At this time, the beam indication information may include at least one of the following: a beam group index, a beam index within a beam group, and a TCI state ID within the group.

[0108] According to the technical solution of the embodiment of the present disclosure, the terminal performs beam measurement based on the configured beam group for beam measurement, or the candidate beam group corresponding to the beam group, reports the measurement results to the network device, and receives beam indication information determined by the network device based on the measurement results and other reference factors. This enables the auxiliary network device to quickly determine the beam indication information when a beam is required to complete a beam scan of the coverage area, thereby improving the efficiency of beam indication.

[0109] FIG7 is a flowchart showing a beam measurement method according to an exemplary embodiment. The beam measurement method is used in a network device. As shown in FIG7 , the method includes the following steps.

[0110] In step S71, beam measurement information is sent to the terminal.

[0111] The beam measurement information is used to configure the beam measurement set of the terminal, and the beam measurement set includes a first beam group for performing beam measurement, and a second beam group corresponding to the first beam group, and the second beam group is a candidate beam group of the first beam group.

[0112] In an embodiment of the present disclosure, a network device may send beam measurement information to a terminal. The beam measurement information may be used to indicate a first beam group for the terminal to perform beam measurement, and a second beam group corresponding to the first beam group. In one example, the beam measurement information may indicate that the terminal performs beam measurement on beam group A1, beam group A2, and so on. N The first beam group, and the beam group B1, beam group B2... beam group B NThe second beam group is a candidate beam group of the first beam group, and N is a positive integer. The second beam group is a candidate beam group of the first beam group, and the second beam group corresponds to the first beam group. The terminal can perform beam measurement based on the first beam group or the second beam group.

[0113] Furthermore, in an embodiment of the present disclosure, the beam measurement information can be used to configure a beam measurement set. The beam measurement set includes the beams indicated by the beam measurement information, and the beams in the beam measurement set include a first beam group and a second beam group corresponding to the first beam group. In one example, the beam measurement set may include a first beam group set, which includes beam group A1, beam group A2, ..., beam group A. N , and the beam measurement set may further include a second beam group set, the second beam group set including beam group B1, beam group B2... beam group B N The second beam group is a candidate beam group of the first beam group. It can also be understood that the first beam group set is a measurement set, and the second beam group set is an extended measurement set. The terminal can perform beam measurement based on the beam measurement set.

[0114] By adopting the technical solution of the embodiment of the present disclosure, the network device sends beam measurement information including the configured beam group and the candidate beam group corresponding to the beam group to the terminal, so that the terminal can perform beam measurement based on the beam group or the candidate beam group. When the beam needs to be used to complete the beam scanning of the coverage area, the complexity of the terminal performing beam measurement can be reduced and the efficiency of the beam measurement can be improved.

[0115] In the embodiments of the present disclosure, beam measurement information may include beam index information or reference signal information corresponding to the beams included in the first beam group and the second beam group. In one example, the beam measurement information may include group index information for the first beam group and the second beam group, as well as beam index information for the beams included in the first beam group and the second beam group. In another example, the beam measurement information may include reference signal information corresponding to the beams included in the first beam group and the second beam group.

[0116] In the embodiment of the present disclosure, the beam measurement set may include one or more first beam groups and one or more second beam groups, wherein each first beam group in the one or more first beam groups corresponds to each second beam group in the one or more second beam groups. Still assuming that the beam measurement set includes the first beam group set, the first beam group set includes beam group A1, beam group A2, ..., beam group A. N , and the beam measurement set may further include a second beam group set, the second beam group set including beam group B1, beam group B2... beam group B NFor example, beam group A1 and beam group B1 may have a corresponding relationship, that is, beam group B1 is a candidate beam group of beam group A1; beam group A2 and beam group B2 may have a corresponding relationship, that is, beam group B2 is a candidate beam group of beam group A2, and so on.

[0117] In embodiments of the present disclosure, the second beam group can be used for beam measurement when the first beam group does not meet measurement requirements. In one example, when the first beam group does not meet the measurement requirements, the terminal directly performs beam measurement on the reference signal corresponding to the beam in the second beam group corresponding to the first beam group, without having to re-acquire beam measurement change information from the network device and re-determine the beam group for beam measurement based on the beam measurement change information. This improves beam measurement efficiency and reduces beam measurement complexity.

[0118] In the disclosed embodiments, to ensure that, when the first beam group fails to meet measurement requirements, the measurement results based on the reference signals corresponding to the beams in the second beam group can also provide a reference for the network device to determine beam indication information, the second beam group and the first beam group can be spatially adjacent. In other words, a beam group spatially adjacent to the first beam group can be selected as a candidate second beam group.

[0119] Spatially adjacent may mean that the coverage areas of different beams, determined by the distances between the beams and the transmit / receive points (TRPs) and the beam angles, are spatially adjacent. In one example, the coverage area of ​​a second beam group, determined by the distance between the second beam group and the transmit / receive point (TRP) and the beam angle of the second beam group, may be spatially adjacent to the coverage area of ​​a first beam group, determined by the distance between the first beam group and the transmit / receive point (TRP) and the beam angle of the first beam group.

[0120] In the disclosed embodiments, a first beam group may include one or more beams, and different first beam groups may include the same beam. In other words, the beams included in different first beam groups may overlap, meaning that the same beam may appear in two or more first beam groups.

[0121] In the disclosed embodiments, a second beam group may include one or more beams, and different second beam groups may include the same beam. In other words, the beams included in different second beam groups may overlap, meaning that the same beam may appear in two or more second beam groups.

[0122] By adopting the technical solution of the embodiment of the present disclosure, the network device sends beam measurement information including the configured beam group and the candidate beam group corresponding to the beam group to the terminal, so that the terminal can perform beam measurement based on the beam group or the candidate beam group, and when the beam group does not meet the measurement requirements, the reference signal corresponding to the beam in the candidate beam group corresponding to the beam group is measured. The network device sends beam measurement change information so that the terminal re-determines the beam group for beam measurement according to the indication of the beam measurement change information, thereby further improving the efficiency of beam measurement and reducing the complexity of beam measurement.

[0123] FIG8 is a flow chart of a beam measurement method according to an exemplary embodiment, wherein step S81 is the same as step S71 in the embodiment corresponding to FIG7 , and is not described again herein. As shown in FIG8 , the method further includes the following steps.

[0124] In step S82, the beam quality threshold is sent to the terminal, and the measurement result reported by the terminal is received.

[0125] In an embodiment of the present disclosure, a network device may send a beam quality threshold to a terminal and receive measurement results reported by the terminal. In one example, the measurement results may include measurement results obtained by the terminal from measuring beam-corresponding reference signals in a second beam group when the terminal determines that the beam quality measured based on the beam-corresponding reference signals in the first beam group is less than the beam quality threshold. In another example, the measurement results may include measurement results obtained by the terminal from measuring beam-corresponding reference signals in the first beam group when the terminal determines that the beam quality measured based on the beam-corresponding reference signals in the first beam group is greater than or equal to the beam quality threshold.

[0126] In an embodiment of the present disclosure, the measurement result may include beam index information corresponding to the measured beam and beam quality information corresponding to the measured beam. The beam index information corresponding to the measured beam may include a beam index or an index of a reference signal corresponding to the beam. The beam quality information corresponding to the measured beam may include at least one of the following: RSRP, RSRQ, SINR, and RSSI.

[0127] Fig. 9 is a flow chart showing a beam measurement method according to an exemplary embodiment. As shown in Fig. 9 , the method further includes the following steps.

The beam measurement set includes a first beam group for performing beam measurement and a second beam group corresponding to the first beam group.

[0129] The second beam group is a candidate beam group of the first beam group.

[0130] In step S92, the beam quality threshold is sent to the terminal, and the measurement result reported by the terminal is received.

[0131] In step S93, in response to determining that the beam qualities measured based on the beam corresponding reference signals in the first beam group and the corresponding second beam group in the beam measurement set are both less than the beam quality threshold, beam measurement change information is sent.

[0132] The beam measurement change information is used to instruct the terminal to receive and measure reference signals corresponding to beams in other first beam groups different from the first beam group in the beam measurement set.

[0133] In an embodiment of the present disclosure, in response to the terminal determining that the beam qualities measured based on the reference signals corresponding to the beams in the first beam group and the corresponding second beam group in the beam measurement set are both less than the beam quality threshold, the network device may send beam measurement change information to the terminal to instruct the terminal to receive and measure the reference signals corresponding to the beams in other first beam groups in the beam measurement set that are different from the first beam group.

[0134] It is understandable that when the beam qualities measured based on the beam-corresponding reference signals in the first beam group and the corresponding second beam group in the beam measurement set are both less than the beam quality threshold, it can be considered that the beams in the first beam group and the corresponding second beam group in the beam measurement set do not meet the quality requirements. In this case, the network device needs to instruct the terminal to re-determine a new first beam group and measure the beam-corresponding reference signals included in the new first beam group. The re-determined new first beam group may be another first beam group in the beam measurement set that is different from the above-mentioned first beam group.

[0135] In one example, the beam measurement information may indicate that the terminal performs beam measurement on multiple first beam groups including beam group A1, beam group A2, beam group A3, etc., and multiple second beam groups including beam group B1, beam group B2, beam group B3, etc., wherein the second beam group is a candidate beam group of the first beam group, and the second beam group corresponds to the first beam group. When the terminal performs beam measurement on the first beam group A1, beam group A2, beam group A3, etc., i and the first beam group A i The corresponding second beam group B i When the beam quality measured by the reference signal of the medium beam is less than the beam quality threshold, the terminal can j The beam corresponding reference signal included in is measured. j Determined by the beam measurement change information sent by the network device.

[0136] Wherein, i and j are different positive integers.

[0138] In step S103, beam indication information is sent.

[0139] The beam indication information is used to indicate the beam determined by the network device for signal reception or transmission.

[0140] In an embodiment of the present disclosure, the network device may further transmit receive beam indication information to the terminal. The beam indication information is used to indicate the beam determined by the network device for signal reception or transmission. The beam indication information may include at least one of the following: a beam group index, a beam index within a beam group, and a TCI state ID within the group.

[0141] According to the technical solution of the embodiment of the present disclosure, the network device sends beam measurement information including the configured beam group and the candidate beam group corresponding to the beam group to the terminal, so that the terminal can perform beam measurement based on the beam group or the candidate beam group, receives the measurement results reported by the terminal, and concurrently sends beam indication information determined based on the measurement results and other reference factors to the terminal. When the beam needs to be used to complete the beam scanning of the coverage area, the network device can quickly determine the beam indication information, thereby improving the efficiency of beam indication.
