Description

[Technical field]

[0001]

[0002] The present application relates to the field of communications technology, and in particular to communication methods and devices. [Background technology]

[0003] As mobile communication technology develops in terms of aspects such as high speed and large amount of data services, the demand for spectrum during communication transmission is increasing. Spectrum in high frequency bands, including centimeter wave and millimeter wave, has a large amount of available bandwidth, and therefore will be an important resource to meet the demand for large capacity and high bandwidth in future communications.

[0004] The remarkable development of mobile communication technology is accompanied by increasing user demands. As users demand greater capacity, transmitting and receiving data with higher quality and multi-antenna technology gains greater interest, and thus beamforming emerges.

[0005] There is currently an urgent need for a solution to meet the requirement for timely measurement reports when the coverage area of ​​the beam is small and the terminal is moving. Summary of the Invention

[0006] The embodiments of the present application provide a communication method and related devices, in which a terminal may report information about a beam that satisfies a condition to a base station in a timely manner, so that the terminal can be handed over to the beam that satisfies the condition in a timely manner, and the service interruption of the terminal can be avoided.

[0007] According to a first aspect, the present application provides a communication method, comprising the steps of: a terminal determining that information about a first beam group of a first cell, which satisfies a condition for reporting a measurement report, is different from information about beams of the first cell included in a previous measurement report.

[0008] The terminal sends a first measurement report to the network device, where the first measurement report includes identification information of beams in the first beam group and signal quality of the beams in the first beam group, or the first measurement report includes a quantity of beams in the first beam group, or the first measurement report includes identification information of beams in the first beam group.

[0009] In a possible design, the terminal determining that information about the first beam group of the first cell that satisfies the condition for reporting a measurement report is different from information about the beams of the first cell included in a previous measurement report may mean that the terminal determines that identification information of the beams of the first beam group of the first cell that satisfies the condition for reporting a measurement report is different from identification information of the beams of the first cell included in the previous measurement report, and / or may mean that the terminal determines that a quantity of beams of the first beam group of the first cell that satisfies the condition for reporting a measurement report is different from a quantity of beams of the first cell included in the previous measurement report.

[0010] The beam identification information includes at least one of a beam identifier, an antenna port identifier for the beam, a reference signal for the beam, and a beam index.

[0011] The conditions for reporting the measurement report include reporting parameters related to a quantity of beams used to determine the signal quality of the first cell, and the reporting parameters include at least one of a signal quality threshold, a hysteresis, a trigger time, and an offset for reporting.

[0012] By implementing this embodiment of the present application, when a terminal acquires through measurement that information about a beam that satisfies a condition for reporting a measurement report is different from information about the beam in a previous measurement report, the terminal may report the measured information about the beam to a network device, so that the terminal is handed over to a beam that satisfies the condition in a timely manner to avoid service interruption for the terminal.

[0013] In a possible design, the first measurement report sent by the terminal may further include a signal quality of a first cell to which the first beam group belongs. Specifically, the manner of determining the signal quality of the first cell may include the terminal determining the signal quality of the first cell based on the signal quality of up to M beams having the highest signal quality in the first cell, or the terminal determining the signal quality of the first cell based on the signal quality of a beam in the first cell whose signal quality is higher than a first preset threshold.

[0014] When the signal quality of each beam of the first cell falls below a first preset threshold, in the prior art, the terminal sets the signal quality of the first cell to a minimum value. However, this method cannot faithfully reflect the signal quality of the first cell, and will result in a relatively large error when the network device compares the signal qualities of the cells. As a result, the network device will perform inaccurate mobility control, which will cause the terminal to interrupt service.

[0015] In a possible design, when the signal quality of each beam of the first cell falls below a first preset threshold, in an optional implementation example, the terminal may determine the signal quality of the first cell based on the signal quality of X beams having the signal quality with the smallest difference from the first preset threshold, thereby accurately reflecting the signal quality of the first cell, helping the network device to perform accurate mobility control, and avoiding service interruption of the terminal. X may be set by the network device or may be predefined. In addition, the value of X is an integer greater than 0.

[0016] Alternatively, when the signal quality of each beam of the first cell falls below the first preset threshold, in another optional implementation example, the terminal may determine the signal quality of the first cell based on the signal qualities of the Y beams whose signal quality differs from the signal quality of the target beam by less than a second preset threshold, where the target beam is the beam whose signal quality differs least from the first preset threshold.

[0017] In one possible design, the terminal may determine a signal quality of the first cell based on an offset, where the offset is determined based on the first quantity.

[0018] In a possible design, the terminal receives first indication information sent by the network device, and the terminal sends a first measurement report, where the first measurement report includes identification information and signal quality of a beam in a first beam group, or the first measurement report includes a quantity of beams in the first beam group, or the first measurement report includes identification information of a beam in the first beam group.

[0019] In this embodiment of the present application, the terminal reports beam measurement information based on the network configuration, so that the network device can make handover decisions more accurately.

[0020] According to a second aspect, the present application provides another communication method, comprising: acquiring signal quality of each beam of a first cell; and when the signal quality of each beam of the first cell is below a first preset threshold, determining the signal quality of the first cell based on signal quality of X beams having a signal quality with the smallest difference from the first preset threshold, where X beams belong to the first cell and X is an integer greater than 0, or determining the signal quality of the first cell based on signal quality of Y beams having a signal quality with a difference with a target beam less than a second preset threshold, where the target beam belongs to the first cell and is the beam having a signal quality with the smallest difference from the first preset threshold, where Y beams belong to the first cell and Y is an integer greater than 0.

[0021] In the present application, the terminal may determine the signal quality of the first cell based on the signal qualities of the X beams having signal qualities that have the smallest difference from a first preset threshold, thereby accurately reflecting the signal quality of the first cell, assisting the network device to perform accurate mobility control, and avoiding service interruption of the terminal.

[0022] According to a third aspect, the present application provides another communication method, comprising: a step of receiving, by a network device, a first measurement report transmitted by a terminal, the first measurement report being transmitted by the terminal when the terminal determines that information about a first beam group of a first cell, which satisfies a condition for reporting the measurement report, is different from information about beams of the first cell included in a previous measurement report, the first measurement report including identities of beams of the first beam group and signal qualities of beams of the first beam group, or the first measurement report including a quantity of beams of the first beam group, or the first measurement report including identities of beams of the first beam group.

[0023] In another possible design, the network device receives an initial signal quality of a first cell and a first quantity of beams used to determine the signal quality of the first cell.

[0024] The network device determines a signal quality of the first cell by referring to an initial signal quality of the first cell and an offset, where the offset is determined based on the first quantity.

[0025] In another possible design, the network device sends first indication information to the terminal, where the first indication information is used to indicate that a first measurement report to be reported by the terminal includes identification information and signal quality of beams of the first beam group, or the first indication information is used to indicate that the first measurement report includes a quantity of beams of the first beam group, or the first indication information is used to indicate that the first measurement report includes identification information of beams of the first beam group.

[0026] In another possible design, the network device sends second indication information to the terminal, where the second indication information is used to indicate a maximum number of identities to be included in a first measurement report to be reported by the terminal and / or a maximum number of signal quality values ​​of beams to be included in the first measurement report.

[0027] According to a fourth aspect, the present application provides a terminal, the terminal comprising a module or unit configured to perform a communication method according to the first or second aspect.

[0028] According to a fifth aspect, the present application provides another terminal, the terminal comprising a processor, a communication module and a memory, the memory configured to store instructions, the processor configured to read the instructions in the memory to perform the communication method according to the first or second aspect.

[0029] According to a sixth aspect, the present application provides a network device, the network device comprising a module or unit configured to perform a communication method according to the third aspect.

[0030] According to a seventh aspect, the present application provides another network device, the network device comprising a processor, a communication module and a memory, the memory configured to store instructions, the processor configured to read the instructions in the memory to perform the communication method according to the third aspect.

[0031] According to an eighth aspect, the present application provides a communication system, the communication system comprising a terminal and a network device, where the terminal is the terminal as described in the fourth or fifth aspect, and the network device is the network device as described in the third aspect.

[0050]

[0051] 1, which is a schematic architecture diagram of a communication system in one embodiment of the present application. The communication system 100 includes a network device 101 and a terminal 102.

[0052] The network device 101 may be a network device using a New Radio (NR) technology, and may be a Node B (NB) of a 3G (e.g., Universal Mobile Telecommunications System (UMTS), Wideband Code Division Multiple Access (WCDMA), and Time Division-Synchronous Code Division Multiple Access (TD-SCDMA)) system, or may be an evolved Node B (eNB) of a Long Term Evolution (LTE) system. In addition, in this embodiment of the present application, the network device 101 may further control the gain value of the direction (or channel) of each transmitting antenna configured as an array antenna to form multiple beams. The network device 101 communicates with the terminal 102 by using the beams. In addition, the network device 101 may have other names, including, but not limited to, a base station (BS) and an evolved base station, in the NR system.

[0053] Any device that may perform data communication with the network device 101 may be considered as the terminal 102. The terminal 102 may be referred to as a mobile station, an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, a user equipment, or other user equipment.

Thereby, the network device 101 configures the beam or cell with the highest signal quality for the terminal 102.

[0055] EMBODIMENT 1

[0056] 2, this embodiment of the present application provides a schematic flowchart of a communication method, which includes but is not limited to the following steps:

[0057] S201: A terminal determines that information about a first beam group of a first cell, which satisfies a condition for reporting a measurement report, is different from information about the beams of the first cell included in a previous measurement report.

[0058] It will be understood that the measurement report may include information about multiple beam groups, each beam group corresponding to one cell. In this specification, the first beam group belongs to a cell, for example, the first cell. The terminal then compares the information about the first beam group of the first cell with the information about the beams of the first cell in the previous measurement report.

[0059] In this embodiment of the present application, the first beam group may have at least one beam, and the information about the first beam group may include identification information of the beams in the first beam group and / or a quantity of the beams in the first beam group.

[0060] Step S201 may be a step in which the terminal determines that the condition for reporting a measurement report is satisfied and the beam identification information of the first beam group of the first cell is different from the beam identification information of the first cell included in the previous measurement report, or a step in which the terminal determines that the condition for reporting a measurement report is satisfied and the number of beams of the first beam group of the first cell is different from the number of beams of the first cell included in the previous measurement report, or a step in which the terminal determines that the condition for reporting a measurement report is satisfied and the beam identification information of the first beam group of the first cell is different from the beam identification information of the first cell included in the previous measurement report and the number of beams of the first beam group is different from the number of beams of the first cell included in the previous measurement report. In this specification, "different" includes "not matching" or "completely different".

[0061] For example, the identification information of the beam of the first beam group is different from the identification information of the beam included in the previous measurement report means that the identification information of the beam of the first beam group does not match the identification information of the beam included in the previous measurement report. For example, it is assumed that the identification information of the beam included in the previous measurement report is beam1-1, beam1-2, and beam1-3, and the terminal determines that the identification information of the beam of the first beam group that satisfies the condition for reporting the measurement report is beam1-1, beam1-2, and beam1-4. The identification information of the beam of the first beam group, beam1-4, does not have the same corresponding identification information in the previous measurement report. In this case, the terminal determines that the identification information of the beam of the first beam group that satisfies the condition for reporting the measurement report is different from the identification information of the beam included in the previous measurement report. Alternatively, the terminal determines that the identification information of the beam included in the previous measurement report is beam1-1, beam1-2, and beam1-3, and the identification information of the beam of the first beam group that satisfies the condition for reporting the measurement report is beam1-1 and beam1-2. The beam identification information beam1-3 in the previous measurement report does not have the same corresponding identification information as the beam identification information of the first beam group. In this case, the terminal determines that the beam identification information of the first beam group that satisfies the condition for reporting the measurement report is different from the beam identification information included in the previous measurement report. Alternatively, the terminal determines that the beam identification information included in the previous measurement report is beam1-1, beam1-2, and beam1-3, and the beam identification information of the first beam group that satisfies the condition for reporting the measurement report is beam1-4, beam1-5, and beam1-6. None of the beam identification information of the first beam group has the same corresponding identification information in the previous measurement report. In this case, the terminal determines that the beam identification information of the first beam group that satisfies the condition for reporting the measurement report is different from the beam identification information included in the previous measurement report.

[0062] The beam identification information may include a beam identifier, a beam antenna port identifier, a beam reference signal, or a beam index, etc., and is used to uniquely identify the beam. In this embodiment of the present application, the beams may be designated by multiple combinations of letters, numbers, or symbols, for example, beam1-1, beam1-2, or beam1-3.

[0063] Referring to FIG. 3, FIG. 3 is a schematic architecture diagram of another communication system according to this embodiment of the present application. As shown in FIG. 3, the measurement report that the terminal plans to report at time T1 includes information on a total of three beams, beam1-1, beam1-2, and beam1-3. As the terminal moves, the terminal obtains through measurement that the beams that meet the condition for reporting the measurement report at time T2 are a total of three beams, beam1-4, beam1-5, and beam1-6. The terminal may determine that the identification information of the beams measured at time T2 that meet the condition for reporting the measurement report is different from the identification information of the beams included in the measurement report at time T1. It should be noted that the beams beam1-1, beam1-2, beam1-3, beam1-4, beam1-5, and beam1-6 belong to the same cell, and the two base stations in FIG. 3 are the same base station, and are just examples of positions at different times.

[0064] It will be understood that the conditions for reporting a measurement report herein may be set by the network device. The conditions for reporting a measurement report may include a quality threshold and a hysteresis, such as, for example, the signal quality of the beam is higher than the quality threshold.

[0065] S202: The terminal sends a first measurement report to the network device, where the first measurement report includes identification information of beams in a first beam group and signal quality of the beams in the first beam group, or the first measurement report includes a quantity of beams in the first beam group, or the first measurement report includes identification information of beams in the first beam group.

[0066] By implementing this embodiment of the present application, when the terminal obtains through measurement that the information on the beam that satisfies the condition for reporting the measurement report is different from the information on the beam in the previous measurement report, the terminal may report the measured information on the beam to the network device, so that the terminal is handed over to the beam that satisfies the condition in a timely manner to avoid the service interruption of the terminal. Referring to Figure 3, when the terminal obtains through measurement that the information on the beam that satisfies the condition at time T2 is different from the information on the beam included in the measurement report at time T1, the terminal may send the information on the beams measured at time T2, beam1-4, beam1-5, and beam1-6, to the network device to assist the network device in making a handover decision, thereby preventing the network device from still selecting a beam from among the beams in the beam information reported at time T1, beam1-1, beam1-2, and beam1-3, and configuring a beam for the terminal, and avoiding the service interruption of the terminal.

[0067] It should be understood that the first measurement report sent by the terminal may further include the signal quality of the first cell to which the first beam group belongs. For a specific manner of determining the signal quality of the first cell, please refer to the description of the following embodiment 2.

[0068] It should be noted that when the first measurement report only includes the identifier or quantity of the beams of the first beam group, the handover decision may be made by further referring to the previously reported signal quality of the first cell or the currently reported signal quality of the first cell. A specific handover decision may be made by referring to the relevant description in the following embodiment or in another manner. This is not limited in this embodiment of the present application.

[0069] EMBODIMENT 2

[0070] This embodiment provides a method for determining the signal quality of a cell, which is applicable to any scenario where the signal quality of a cell needs to be determined.

[0071] Optionally, the method of embodiment 2 may be independent of other embodiments, or may be combined with embodiment 1, embodiment 3, or embodiment 4.

[0072] As shown in FIG. 4, the method for determining the signal quality of a cell may include the following steps.

[0073] S401: A terminal obtains the signal quality of each beam of a first cell.

[0074] S402a: Determine a signal quality of a first cell based on signal qualities of up to M beams having the highest signal quality in the first cell.

[0075] M is a positive integer greater than or equal to 1, and M may be set or predefined.

[0076] Optionally, the terminal may calculate an average value of the signal qualities of up to M beams in order from the one with the highest signal quality to the other, and use the calculated average value as the signal quality of the cell.

[0077] For example, the signal qualities of the beams of a cell, beam1-4, beam1-5, and beam1-6, are 2 dB, 12 dB, and 9 dB, respectively, and M is equal to 2. In this case, the terminal calculates the average value of the signal qualities of the two beams, beam1-5 and beam1-6, in descending order of signal quality, as follows: (12+9) / 2=10.5 dB, and uses the average value 10.5 dB as the signal quality of the cell.

[0078] Optionally, the terminal may alternatively determine the signal quality of the first cell in the following manner.

[0079] S402b: Determine the signal quality of the first cell based on the signal quality of a beam in the first cell whose signal quality is higher than a first preset threshold. Optionally, the terminal may use the average value of the signal quality of the beam whose signal quality is higher than the first preset threshold as the signal quality of the cell. It should be understood that the first preset threshold in this specification may be set by the network device or may be predefined. This is not limited in this embodiment of the present application.

[0080] For example, the signal qualities of beams, beam1-4, beam1-5, and beam1-6, of the first cell are 2 dB, 12 dB, and 9 dB, respectively, and the first preset threshold is 5 dB. In this case, the terminal calculates the average value of the signal qualities of beams, beam1-5 and beam1-6, whose signal qualities are higher than the first preset threshold of 5 dB, as follows: (12+9) / 2=10.5 dB, and uses the average value 10.5 dB as the signal quality of the first cell.

[0081] When the signal quality of each beam of the first cell falls below a first preset threshold, in the prior art, the terminal sets the signal quality of the first cell to a minimum value. However, this method cannot faithfully reflect the signal quality of the first cell, and will result in a relatively large error when the network device compares the signal qualities of the cells. As a result, the network device will perform inaccurate mobility control, which will cause the terminal to interrupt service.

[0082] S402c: When the signal quality of each beam of the first cell falls below a first preset threshold, the terminal may determine the signal quality of the first cell based on the signal quality of X beams having the smallest signal quality difference from the first preset threshold, thereby accurately reflecting the signal quality of the first cell, helping the network device to perform accurate mobility control, and avoiding the service interruption of the terminal. X may be set by the network device or may be predefined. And the value of X is an integer greater than 0.

[0083] For example, the signal qualities of beams, beam1-4, beam1-5, and beam1-6, of the first cell are 2 dB, 12 dB, and 9 dB, respectively, the first preset threshold is 15 dB, and the signal quality of each beam of the first cell is below 15 dB. When X is equal to 1, the terminal may use the signal quality of the beam, 12 dB, which is the smallest difference from the first preset threshold of 15 dB, as the signal quality of the first cell.

[0084] S402d: When the signal quality of each beam of the first cell falls below a first preset threshold, the terminal may determine the signal quality of the first cell based on the signal quality of Y beams whose difference with the signal quality of the target beam is less than a second preset threshold. Here, the target beam is the beam whose signal quality has the smallest difference with the first preset threshold. Y may be set by the network device or may be predefined. And, the value of Y is an integer greater than 0. The target beam may be determined based on a certain condition. For example, the beam with the highest signal quality may be used as the target beam.

[0085] For example, the signal qualities of beams, beam1-4, beam1-5, and beam1-6, of the first cell are 2 dB, 12 dB, and 9 dB, respectively, the first preset threshold is 15 dB, and the second preset threshold is 4 dB. It can be seen that the signal quality of each beam of the first cell is below 15 dB. The beam, beam1-5, having the highest signal quality in the first cell may be set as the target beam. In this case, the terminal may determine the signal quality of the cell based on the signal qualities of the beams, 12 dB and 9 dB, whose difference from the signal quality of the target beam, beam1-5, is less than the second preset threshold of 4 dB.

[0086] Optionally, the terminal may obtain an average value of the signal qualities of beams whose difference from the signal quality of the target beam is less than a second preset threshold, and use the average value as the signal quality of the cell.

[0087] Continuing with the above example, the terminal determines that the signal qualities of the beams whose difference with the signal quality of the target beam, beam1-5, is less than the second preset threshold of 4 dB are 12 dB and 9 dB. In this case, the terminal may obtain the average value of the signal qualities of 12 dB and 9 dB, i.e., (12+9) / 2=10.5 dB, and use the average value of 10.5 dB as the signal quality of the cell.

[0088] In this embodiment of the present application, a rollback mechanism is used to reflect the cell's signal quality as accurately as possible, preventing network devices from making inaccurate mobility decisions.

[0089] S403: The terminal sends the determined signal quality of the first cell to the network device.

[0090] EMBODIMENT 3

[0091] To improve the robustness of handover decisions, yet another embodiment of the present application provides a communication method, which is applicable to any scenario requiring a handover decision.

[0092] Optionally, the method of embodiment 3 may be independent of other embodiments, or may be combined with embodiment 1, embodiment 2, or embodiment 4.

[0093] As shown in FIG. 5, the communication method may include the following steps.

[0094] S501: A terminal obtains a first quantity of beams used to determine a signal quality of a first cell.

[0095] S502: A terminal determines a signal quality of a first cell based on an offset, where the offset is determined based on a first quantity.

[0096] There is a specific correspondence between the first quantity and the offset, which may be set by the network device for the terminal, negotiated between the network device and the terminal, or predefined in a communication protocol.

[0097] Optionally, the correspondence may be explicit or implicit.

[0098] Specifically, an explicit relationship means that there is a direct correspondence between the offset and the first quantity, for example, when the first quantity is less than 5, the offset is 1, and when the first quantity is 5 or more, the offset is 2.

[0099] The implicit relationship means determining a coefficient of a basic measurement offset, delta, based on the first quantity to obtain a further offset. The basic measurement offset, delta, may be configured by the network device for the terminal, negotiated between the network device and the terminal, or predefined in a communication protocol.

[0100] Optionally, the coefficient of delta may be a first quantity. For example, the base measurement offset, delta, is set by the network device, and the first quantity is 4. In this case, the coefficient of delta is 4, and the offset is 4×delta.

[0101] After the offset is obtained in the above manner, the signal quality of the first cell directly obtained based on the beam may be adjusted.

[0102] For example, the signal quality of the first cell directly obtained based on the beam is 10.5 dB, the first quantity is 2, and the offset corresponding to the first quantity being less than 5 is 2. In this case, the terminal determines that the final signal quality of the cell is Q=10.5+2. Alternatively, the first quantity is 4, the basic measurement offset delta is 0.6, and the offset is 4×0.6. In this case, the terminal determines that the final signal quality of the cell is Q=10.5+2.4.

[0103] S503: The terminal reports the signal quality of the first cell to the network device.

[0104] It should be noted that in this embodiment of the present application, the terminal transmits the finally determined signal quality of the cell to the network device. Optionally, alternatively, the adjustment of the signal quality of the cell may be implemented by the network device.

[0105] For example, S502 may not be performed, but when reporting the signal quality of the first cell to the network device in S503, the terminal may further report a first quantity to the network device, so that the network device may adjust the reported signal quality of the first cell according to a method similar to that described in S502.

[0106] Optionally, some other parameters may also be adjusted in the terminal or network device according to a similar method to that described in S502 and S503. The above-mentioned parameters may include at least one of a signal quality threshold, a hysteresis, a trigger time, and an offset for reporting. It should be understood that different parameters may have different base offsets or different corresponding relationships between offsets and the first quantity. In this embodiment of the present application, no examples are given one by one.

[0107] In this embodiment of the present application, by adjusting the above-mentioned parameters with reference to the first quantity, the robustness of the handover decision can be improved.

[0108] In each of the above-described embodiments, the terminal may report the signal quality of the beam and / or the signal quality of the cell to the network device by using measurement reports.

[0115] The measurement information of the beams includes, but is not limited to, beam identity and beam signal quality, or beam quantity, or beam identity.

The first instruction information indicates that the measurement report should hold the identification information of the beams and the signal qualities of the beams. In this case, the terminal transmits the four identification information, beam1-4, beam1-5, beam1-6, and beam1-7, and the corresponding four signal quality values, 2 dB, 12 dB, 9 dB, and 10 dB, to the network device by the measurement report. Alternatively, the first instruction information indicates that the measurement report should hold the quantity of beams. In this case, the terminal transmits the quantity 4 of the beams that satisfy the condition for reporting a measurement report to the network device by the measurement report. Alternatively, the first instruction information indicates that the measurement report should hold the identification information of the beams. In this case, the terminal transmits four pieces of identification information, beam1-4, beam1-5, beam1-6, and beam1-7, to the network device.

[0117] Optionally, the terminal receives second indication information sent by the network device. The second indication information is used to indicate the maximum quantity Z of the beams of the first beam group. For the meaning and determination manner of the first beam group, please refer to the relevant description in the above embodiment. Details are not described again here.

[0118] Optionally, the second indication information may be sent together with another reporting condition parameter and / or the first indication information, or may be sent separately. The terminal may use the second indication information in combination with the other reporting condition parameter and / or the first indication information.

[0119] The maximum number of beam identifiers held by the terminal in the measurement report may be limited by using the second indication information. Z may be different from or the same as the number of beams used during the measurement.

[0120] S602: The terminal sends a first measurement report, where the first measurement report includes identification information and signal quality of a beam in a first beam group, or the first measurement report includes a quantity of beams in the first beam group, or the first measurement report includes identification information of a beam in the first beam group.

[0121] In this embodiment of the present application, the terminal reports beam measurement information based on the network configuration, so that the network device can make handover decisions more accurately.

[0122] It should be understood that the communication method described in embodiment 4 is applicable to any scenario requiring a handover decision. Optionally, the method of embodiment 4 may be independent of or combined with other embodiments.

[0123] It should be understood that the terminal may perform some or all of the steps of the embodiment. These steps or operations are merely examples. In this embodiment of the present application, other operations or variations of operations may also be performed.
