[0120] In some embodiments, obtaining data, information, etc. may comply with the laws and regulations of the country where the data is obtained.

[0121] In some embodiments, data, information, etc. may be obtained with the user's consent.

[0122] In addition, each element, each row, or each column in the table of the embodiment of the present disclosure can be implemented as an independent embodiment, and the combination of any elements, any rows, and any columns can also be implemented as an independent embodiment.

[0123] Due to the rapid attenuation of high-frequency channels, beam-based transmission and reception are required to ensure coverage. For example, in NR, especially when the communication frequency band is in frequency range (FR) 2, beam-based transmission and reception can be used to ensure coverage. FR2 refers to communication frequency bands above 7 gigahertz (GHz). Currently, base stations often configure periodic, semi-persistent, or aperiodic beam reporting. However, in reality, changes in beam quality are the most timely information for terminals. The length of the reporting period configured by the base station, or the timing of aperiodic reporting, may not be optimal. For example, if the base station configures periodic beam reporting, if the period is too short, the best K beams reported twice may be the same, wasting signaling. If the period is too long, the beam may change before the reporting time arrives, affecting communication quality. Similarly, with aperiodic reporting, the base station may trigger the terminal to report too early or too late, making it inappropriate.

[0124] Therefore, the present disclosure provides a communication method, in which the terminal determines the trigger condition and reports the beam report when the trigger condition is met, which can avoid the situation where the base station triggers the terminal to report, resulting in the reporting being too early or too late.

[0125] FIG1 is a schematic diagram showing a communication system architecture according to an embodiment of the present disclosure.

[0126] As shown in FIG1 , a communication system 100 includes a terminal 101 and a network device 102 .

[0136] FIG2 is a schematic diagram illustrating an interaction of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the present disclosure embodiment relates to a communication method for use in a communication system 100, the method comprising:

[0137] Step S2101 , the network device 102 sends first information to the terminal 101 .

[0138] In some embodiments, the terminal 101 receives first information sent by the network device 102. The first information is used to indicate a trigger condition and / or a parameter corresponding to the trigger condition.

[0139] In some embodiments, the network device may indicate the trigger condition to the terminal through the first information, so that the terminal can subsequently report a beam report to the network device when the trigger condition is met.

[0140] Optionally, the first information may indicate a trigger condition, and the parameters corresponding to the trigger condition may be determined by the terminal in other ways. For example, the terminal may determine the parameters corresponding to the trigger condition based on fixed values ​​specified in a protocol. For another example, the terminal may determine the parameters corresponding to the trigger condition on its own.

[0141] Optionally, the first information may indicate a parameter corresponding to the trigger condition. For example, the terminal may determine the trigger condition in other ways, and the network device may indicate the parameter corresponding to the trigger condition.

[0142] Optionally, the first information may indicate a trigger condition and a parameter corresponding to the trigger condition.

[0143] In some embodiments, the trigger condition includes at least one of the following: the beam measurement results meet the same event N1 times in a row; within a first time period, all beam measurement results meet the same event; within the first time period, the number of times the beam measurement results meet the same event is greater than N2; within the first time period, the number of times the beam measurement results do not meet the same event is less than N3; within the first time period, the ratio of the number of times the beam measurement results meet the same event to the number of beam measurements is greater than or equal to a first threshold; within the first time period, the ratio of the number of times the beam measurement results do not meet the same event to the number of beam measurements is less than or equal to a second threshold; and the filtered value of the beam measurement result meets the event, where the filtered value is a filtered value within the second time period. The number of beam measurements can represent the total number of beam measurements performed within the first time period, i.e., the number of beam measurements measured within the first time period. Alternatively, the number of beam measurements can represent the total number of successful beam measurements performed within the first time period, i.e., the number of successful beam measurements performed within the first time period. For example, if the beam measurement result is not noise, the beam measurement is considered successful.

[0144] Optionally, the trigger condition may include the beam measurement results meeting the same event N1 times in a row. N1 is a positive integer. That is, if the beam measurement results meet the same event N1 times in a row, the trigger condition is considered met, and the terminal can send a beam report to the network device. For example, N1 can be a positive integer greater than 1. That is, if a beam report is reported only after an event is met once, it may not reflect the channel characteristics over a period of time, which may be a sudden condition. Reporting a beam report may cause a ping-pong effect. The ping-pong effect refers to the switching back and forth between two different states. In this embodiment, the beam report is reported only after the same event is met N1 times in a row. This better reflects the channel characteristics over a period of time and effectively avoids the ping-pong effect. For example, a counter can be defined. The first time a beam measurement result is found to meet a certain event, the counter is incremented by 1. If the same event is met N1 times in a row, it is determined that the trigger event has been met. That is, if the initial value of the counter is 0, the transmission of the beam report is triggered when the counter is incremented to N.

[0145] Optionally, the trigger condition may include: within a first time period, all beam measurement results satisfy the same event. That is, if the beam is measured multiple times within the first time period and the measurement results all satisfy the same event, the trigger condition may be considered to be satisfied. For example, a timer may be defined. When the beam measurement result is first found to satisfy a certain event, the timer begins counting down. If, at the end of the timer, no beam measurement result fails to satisfy the event, the trigger condition is determined to be satisfied, triggering the sending of the beam report.

[0146] Optionally, the trigger condition may include: within the first duration, the beam measurement results satisfy the same event a number of times greater than N2. That is, if the beam is measured multiple times within the first duration and more than N2 of the multiple measurement results satisfy the same event, the trigger condition may be considered to be satisfied. N2 is a positive integer. For example, N2 may be a positive integer greater than 1. That is, if a beam report is submitted after only one event is satisfied, the characteristics of the channel over a period of time may not be reflected. If a beam report is submitted, a ping-pong effect may result. In this embodiment, the beam measurement results satisfy the same event a number of times greater than N2 within the first duration, which better reflects the characteristics of the channel over a period of time and effectively avoids the ping-pong effect.

[0147] Optionally, the trigger condition may include: within the first duration, the number of times that the beam measurement results do not satisfy the same event is less than N3. That is, if within the first duration, the beam is measured multiple times and fewer than N3 of the multiple measurement results do not satisfy the same event, the trigger condition is considered satisfied. N3 is a positive integer.

[0148] Optionally, the trigger condition may include: within the first duration, a ratio of the number of times the beam measurement results satisfy the same event to the number of beam measurements is greater than or equal to a first threshold. That is, if the beam is measured multiple times within the first duration and the ratio of the number of measurement results satisfying the same event is greater than or equal to the first threshold, the trigger condition is considered to be met.

[0149] Optionally, the trigger condition may include: within the first duration, the ratio of the number of times the beam measurement results do not meet the same event to the number of beam measurements is less than or equal to a second threshold. In other words, if the beam is measured multiple times within the first duration, and the ratio of the number of measurement results that do not meet the same event is less than or equal to the second threshold, the trigger condition is considered to be met.

[0150] Optionally, the trigger condition may include: a filtered value of a measurement result of the beam satisfies an event, where the filtered value is a filtered value within a second time period. That is, the measurement results within the second time period may be filtered to obtain a filtered value. If the filtered value satisfies the event corresponding to the trigger condition, the trigger condition may be considered satisfied.

[0151] In some embodiments, the first duration and the second duration may be the same or different. The second duration may correspond to a filtering operation. That is, each filtering operation may correspond to a second duration.

[0152] In some embodiments, filtering may include, but is not limited to, layer 1 filtering (L1 filtering) and layer 3 filtering (L3 filtering). L1 filtering may employ a linear averaging filtering approach. For example, L1 filtering may be performed on the measurement results within the second time period, i.e., a linear average of the measurement results within the second time period may be calculated. Alternatively, L1 filtering may be implemented on a terminal basis. L3 filtering may be implemented using the following formula: (1-a)P1+a*P2. P1 represents the measurement results after multiple previous filtering attempts. For example, P1 may represent the result after L3 filtering. P2 represents the result of the most recent L1 filtering attempt. a is a parameter less than 1 and greater than 0. Specifically, the results P1 of the multiple previous L3 filtering attempts and the result of the most recent L1 filtering attempt may be substituted into the formula (1-a)P1+a*P2 to obtain the value that represents the most recent L3 filtering result.

[0153] In some embodiments, the sizes of N1, N2, N3, the first threshold, and the second threshold are not limited in this disclosure. It is understandable that if the trigger condition is that the measurement result of the beam meets the same event N1 times in a row. Then the parameter corresponding to the trigger condition may include N1. If the trigger condition is that within the first time period, the ratio of the number of times the measurement result of the beam meets the same event to the number of beam measurements is greater than or equal to the first threshold. Then the parameter corresponding to the trigger condition may include the first threshold. This disclosure does not give examples one by one. For the parameters corresponding to the trigger condition, such as N1, it can be indicated by the network device through the first information, or it can be determined by the terminal through other means. For example, it can be determined by the terminal according to the fixed value specified in the protocol, or it can be determined by the terminal itself, and this disclosure does not limit it.

[0154] In some embodiments, the event includes at least one of the following: the measurement result of at least one first beam is less than a third threshold; the measurement result of at least one second beam is greater than a fourth threshold; the measurement result of at least one second beam is greater than the measurement result of at least one first beam, and the difference is greater than a fifth threshold.

[0155] In some embodiments, the event may be that the measurement result of the first beam is less than a third threshold. That is, when the measurement result of the first beam is less than the third threshold, the event is determined to be met. For example, a trigger condition may be: the measurement results of the beams meet the same event N1 times in a row. If the same event is that the measurement result of at least one first beam is less than the third threshold, then the trigger condition is that the measurement result of at least one first beam is less than the third threshold N1 times in a row. That is, when the measurement result of the first beam is less than the third threshold N1 times in a row, the trigger condition may be determined to be met, triggering the reporting of a beam report. Another example may be: within a first time period, the measurement results of the beams meet the same event more than N2 times. If the same event is that the measurement result of at least one first beam is less than the third threshold, then the trigger condition is that the measurement result of at least one first beam is less than the third threshold more than N2 times in the first time period. That is, if at least N2 measurement results are less than the third threshold within the first time period, the trigger condition may be determined to be met, triggering the reporting of a beam report. This disclosure does not provide examples of various trigger conditions, but is not limited to these.

[0156] It is understood that if the measurement result of at least one first beam is less than the third threshold, the quality of the first beam can be considered poor, and a beam report can be submitted to facilitate network equipment to perform beam measurement, beam management, beam switching, and other scheduling. For example, a reference signal resource for second beam measurement or switching from the first beam to the second beam can be configured.

[0157] In some embodiments, the event may be that the measurement result of the second beam is greater than a fourth threshold. That is, when the measurement result of the second beam is greater than the fourth threshold, the event is determined to be met. For example, a trigger condition may be: the measurement results of a beam meet the same event N1 times in a row. If the same event is that the measurement result of the second beam is greater than the fourth threshold, then the trigger condition is that the measurement result of the second beam is greater than the fourth threshold N1 times in a row. That is, when the measurement result of the second beam is greater than the fourth threshold N1 times in a row, the trigger condition may be determined to be met, triggering the reporting of a beam report. Another example may be: within a first duration, the measurement results of a beam meet the same event more than N2 times. If the same event is that the measurement result of the second beam is greater than the fourth threshold, then the trigger condition is that within the first duration, the number of measurement results of the second beam that are greater than the fourth threshold is greater than N2. That is, if at least N2 measurement results are greater than the fourth threshold within the first duration, then the trigger condition may be determined to be met, triggering the reporting of a beam report. This disclosure does not provide examples of various trigger conditions, but is not limited to these.

[0158] It is understood that if the measurement result of the second beam is greater than the fourth threshold, the quality of the second beam can be considered to be high, and a beam report can be reported to facilitate the network device to perform beam management, beam switching, and other scheduling. For example, switching from the first beam to the second beam.

[0159] In some embodiments, an event can be that the measurement result of at least one second beam is greater than the measurement result of at least one first beam, and the difference is greater than a fifth threshold. That is, if the measurement result of at least one second beam is greater than the measurement result of at least one first beam, and the difference between the two is greater than the fifth threshold, the event can be determined to have been met. For example, if the measurement result of second beam A is greater than the measurement result of first beam B, and the difference between the measurement results of A and B is greater than the fifth threshold, the event can be determined to have been met. The difference in this embodiment can be understood as the absolute value of the difference. For example, consider a trigger condition: the measurement results of a beam meet the same event N1 times in a row. If the same event is that the measurement result of the second beam is greater than the measurement result of the first beam, and the difference between the measurement results of the second beam and the measurement results of the first beam is greater than the fifth threshold, then the trigger condition is that the measurement result of the second beam is greater than the measurement result of the first beam N1 times in a row, and the difference between the measurement results of the second beam and the measurement results of the first beam is greater than the fifth threshold each time during these N1 times. This disclosure does not provide examples of various trigger conditions, but is not limited to these.

[0160] In some embodiments, the values ​​of the third threshold, the fourth threshold, and the fifth threshold are not limited. The third threshold, the fourth threshold, and the fifth threshold can be indicated to the terminal by the network device in the first message as parameters corresponding to the trigger condition. Alternatively, the terminal can determine the values ​​in other ways.

[0161] In some embodiments, "greater than" in each embodiment of the present disclosure may also mean "greater than or equal to," and "less than" may also mean "less than or equal to," and the present disclosure does not limit this.

[0162] In some embodiments, the first beam includes at least one of the following: the beam most recently indicated by the network device; the best beam in the most recently sent beam report; all beams in the most recently sent beam report; and the beam with the worst quality in the most recently sent beam report.

[0163] Optionally, the first beam may be the beam most recently indicated by the network device. The beam most recently indicated by the network device includes at least one of the following: the transmission configuration indication (TCI) status corresponding to the channel; the TCI status corresponding to the reference signal. The channel may, for example, include at least one of the following: physical downlink control channel (PDCCH), physical downlink shared channel (PDSCH), physical uplink control channel (PUCCH), physical uplink shared channel (PUSCH). The reference signal may, for example, include at least one of the following: channel state information reference signal identity (CSI-RS), sounding reference signal (SRS). The beam most recently indicated by the network device may be the TCI status indicated by the medium access control control element (MAC CE); or the beam most recently indicated by the network device may be the TCI status corresponding to the codepoint indicated by the downlink control information (DCI). That is, after the MAC CE activates the TCI states corresponding to multiple codepoints, the DCI indicates one of the codepoints, so that the beam most recently indicated by the network device is the TCI state corresponding to the codepoint indicated by the DCI. The beam most recently indicated by the network device can be an indicated TCI state or a unified TCI state applicable to at least two channels / reference signals, or a TCI state independently indicated for one channel / reference signal. The TCI state includes at least one of a joint TCI state, a downlink (DL) TCI state, and an uplink (UL) TCI state.

[0164] Optionally, the first beam may be the best beam in the most recently sent beam report. The best beam is the beam with the best quality. There may be one or more best beams in the beam report.

[0165] Optionally, the first beam may be all beams in the most recently transmitted beam report. For example, if the most recently transmitted beam report contains multiple beams, the first beam may be all beams in the most recently transmitted beam report.

[0166] Optionally, the first beam may be the beam with the worst quality in the most recently sent beam report. For example, if the most recently sent beam report contains multiple beams, the first beam may be the beam with the worst quality in the most recently sent beam report.

[0167] In some embodiments, the second beam is a beam other than the first beam. For example, the first beam is the beam most recently indicated by the network device, and the second beam may be a beam other than the beam most recently indicated by the network device. The beam most recently indicated by the network device may refer to the introduction in the above embodiments, and the present disclosure will not elaborate on it here. For another example, the first beam is the best beam in the most recently sent beam report, and the second beam may be a beam other than the best beam in the most recently sent beam report. Or the second beam may be a beam other than the beam in the most recently sent beam report. For another example, the first beam is all beams in the most recently sent beam report, and the second beam may be a beam other than the beam in the most recently sent beam report. For another example, the first beam is the beam with the worst quality in the most recently sent beam report, and the second beam may be a beam other than the beam with the worst quality in the most recently sent beam report. Or the second beam may be a beam other than the beam in the most recently sent beam report.

[0168] In some embodiments, the parameters corresponding to the trigger condition include at least one of the following: the value of N1; the value of N2; the value of N3; the first threshold; the second threshold; the third threshold; the fourth threshold; and the fifth threshold.

[0169] Optionally, the parameter corresponding to the trigger condition may include the value of N1. For example, if the trigger condition is that the beam measurement results meet the same event N1 times in a row, the parameter corresponding to the trigger condition may include the value of N1. The value of N1 can be used to determine the trigger condition. For example, assuming the value of N1 is A, the terminal can determine, based on A, that the trigger condition is that the beam measurement results meet the same event A times in a row.

[0170] Optionally, the parameter corresponding to the trigger condition may include the value of N2. For example, when the trigger condition is that the number of times the beam measurement results meet the same event within the first duration is greater than N2, the parameter corresponding to the trigger condition may include the value of N2. The value of N2 may be used to determine the trigger condition.

[0171] Optionally, the parameter corresponding to the trigger condition may include the value of N3. For example, when the trigger condition is that the number of times the beam measurement results do not meet the same event within the first duration is less than N3, the parameter corresponding to the trigger condition may include the value of N3. The value of N3 may be used to determine the trigger condition.

[0172] Optionally, the parameters corresponding to the trigger condition may include a first threshold. For example, when the trigger condition is that the ratio of the number of times the beam measurement results meet the same event within the first duration to the number of beam measurements is greater than or equal to the first threshold, the parameters corresponding to the trigger condition may include the first threshold. The first threshold may be used to determine the trigger condition.

[0173] Optionally, the parameters corresponding to the trigger condition may include a second threshold. For example, when the trigger condition is that the ratio of the number of times the beam measurement results do not meet the same event within the first duration to the number of beam measurements is less than or equal to the second threshold, the parameters corresponding to the trigger condition may include the second threshold. The second threshold may be used to determine the trigger condition.

[0174] Optionally, the parameters corresponding to the trigger condition may include a third threshold. For example, when the event is: the measurement result of at least one first beam is less than the third threshold, the parameters corresponding to the trigger condition of the event may include the third threshold. The third threshold is used to determine the event.

[0175] Optionally, the parameters corresponding to the trigger condition may include a fourth threshold. For example, when the event is: the measurement result of the second beam is greater than the fourth threshold, the parameters corresponding to the trigger condition of the event may include the fourth threshold. The fourth threshold is used to determine the event.

[0176] Optionally, the parameters corresponding to the trigger condition may include a fifth threshold. For example, when the event occurs: the measurement result of the second beam is greater than the measurement result of the first beam, and the difference between the measurement result of the second beam and the measurement result of the first beam is greater than the fifth threshold, the parameters corresponding to the trigger condition for this event may include the fifth threshold. The fifth threshold is used to determine this event.

[0177] In some embodiments, the first information is also used to indicate at least one first identifier and at least one of the following items corresponding to the first identifier: event; trigger condition; parameter corresponding to the trigger condition; reference signal resource; reference signal resource set; reported amount.

[0178] In some embodiments, the network device may indicate the first identifier and the event corresponding to the first identifier to the terminal based on the first information. After receiving the first identifier and the event corresponding to the first identifier, the terminal may determine the trigger condition. For example, assuming that the event corresponding to the first identifier is X, and event X is that the measurement result of at least one first beam is less than the third threshold, the trigger condition may be determined to be that the measurement result of the beam meets event X for N1 consecutive times, that is, the trigger condition may be determined to be that the measurement result of the first beam is less than the third threshold for N1 consecutive times. For another example, the trigger condition may be determined to be that the measurement result of the beam meets X for more than N2 times within the first time length, that is, the trigger condition may be determined to be that the measurement result of at least one first beam is less than the third threshold for more than N2 times within the first time length. This disclosure does not give examples one by one. After the network device indicates the first identifier, it may directly indicate the first identifier in the second information when subsequently sending the second information, so as to activate the trigger condition determined by the event corresponding to the first identifier.

[0179] In some embodiments, the network device may indicate the first identifier and the trigger condition corresponding to the first identifier to the terminal based on the first information. For example, the trigger condition corresponding to the first identifier is that the measurement result of the beam meets the same event N1 times in a row. For another example, the trigger condition corresponding to the first identifier is that within the first time period, the number of times the measurement result of the beam meets the same event is greater than N2. This disclosure does not give examples one by one. After the network device indicates the first identifier, it can directly indicate the first identifier in the second information when sending the second information subsequently, so as to activate the trigger condition corresponding to the first identifier.

[0180] In some embodiments, the network device may indicate the first identifier and the parameter corresponding to the trigger condition corresponding to the first identifier to the terminal based on the first information. After receiving the first identifier and the parameter corresponding to the trigger condition corresponding to the first identifier, the terminal may determine the trigger condition. For example, assuming that the parameter corresponding to the trigger condition corresponding to the first identifier is N1, the terminal may determine that the trigger condition is that the measurement result of the beam meets the same event N1 times in a row. For another example, assuming that the parameter corresponding to the trigger condition corresponding to the first identifier is N2, the terminal may determine that the trigger condition is that the measurement result of the beam meets the same event for more than N2 times within the first time length. This disclosure does not give examples one by one. After the network device indicates the first identifier, it may directly indicate the first identifier in the second information when subsequently sending the second information, so as to activate the trigger condition corresponding to the parameter corresponding to the first identifier.

[0181] In some embodiments, the network device may indicate a first identifier and a reference signal resource corresponding to the first identifier to the terminal based on the first information. The reference signal resource may be a reference signal resource transmitted periodically, a reference signal resource transmitted semi-persistently, a reference signal resource transmitted aperiodically, etc., which is not limited in this disclosure. For example, after receiving the first identifier and the reference signal resource corresponding to the first identifier, the terminal may perform measurements based on the reference signal resource to obtain beam measurement results. The beam measurement results may then be used to determine whether a trigger condition is met.

[0182] In some embodiments, the network device may indicate a first identifier and a reference signal resource set corresponding to the first identifier to the terminal based on the first information. The reference signal resource set may include, for example, a channel measurement resource (CMR) and / or an interference measurement resource (IMR). For example, after receiving the first identifier and the reference signal resource set corresponding to the first identifier, the terminal may perform measurements based on the reference signal resources in the reference signal resource set to obtain beam measurement results. The beam measurement results may then be used to determine whether a trigger condition is met.

[0183] In some embodiments, the network device may indicate a first identifier and a reporting amount corresponding to the first identifier to the terminal based on the first information. For example, the reporting amount may include layer 1 reference signal receiving power (layer 1-reference signal receiving power / reference signal received power, L1-RSRP) or layer 1 signal to interference plus noise ratio (layer 1signal to interference plus noise ratio, L1-SINR). The terminal may measure the reference signal resource corresponding to the beam based on the reporting amount indicated by the first information to obtain L1-RSRP or L1-SINR. L1-RSRP or L1-SINR, that is, the measurement result of the beam, can be used to determine whether to report the beam report.

[0184] In some embodiments, the network device may indicate a first identifier and a reporting type corresponding to the first identifier to the terminal based on the first information. The reporting type is the manner in which the beam report is reported. For example, the reporting type may include semi-persistent beam reporting or aperiodic beam reporting.

[0185] It is understood that in the various embodiments of the present disclosure, reporting a beam report and sending a beam report to a network device can be used interchangeably. Of course, in the present disclosure, the terminal can also report a beam report to other entities, which is not limited in the present disclosure.

[0186] In some embodiments, after receiving the first information, the terminal may independently report a beam report in response to the trigger condition indicated by the first information being met. Alternatively, after receiving the second information sent by the network device, the terminal may report a beam report in response to the trigger condition indicated by the first information being met. The second information is used to activate the trigger condition indicated by the first information, or the second information is used to instruct the terminal to report a beam report in response to the trigger condition indicated by the first information being met.

[0187] In some embodiments, the first information may be radio resource control inactive (RRC).

[0188] In some embodiments, the name of the first information is not limited, and it can be, for example, "instruction information", "configuration information", etc.

[0189] The names of the first beam and the second beam involved in each embodiment of the present disclosure are not limited. For example, the first beam can also be called the current beam, and the second beam can also be called the candidate beam.

[0190] Step S2102: Terminal 101 determines a trigger condition.

[0191] In some embodiments, the terminal 101 may determine the trigger condition based on the first information sent by the network device 102. The first information is used to indicate the trigger condition and / or a parameter corresponding to the trigger condition.

[0192] In some embodiments, the terminal 101 may also determine the trigger condition in other ways. For example, the terminal may determine the trigger condition based on an event configured by a network device. For another example, the terminal may determine the trigger condition on its own.

[0193] Step S2103 , the network device 102 sends second information to the terminal 101 .

[0194] In some embodiments, terminal 101 receives second information sent by network device 102. The second information is used to activate a trigger condition, or to instruct the terminal to send a beam report to the network device in response to a measurement result corresponding to the beam meeting the trigger condition.

[0195] In some embodiments, after receiving the first information, the terminal may determine a trigger condition based on the first information. However, it may not temporarily report a beam report in response to the trigger condition being met. Instead, it may report a beam report in response to the trigger condition being met after receiving the second information sent by the network device.

[0196] In some embodiments, the second information may be a MAC CE. The network device activates the trigger condition indicated by the first information via the MAC CE. After the trigger condition is activated, the terminal sends a beam report to the network device when the trigger condition is met.

[0197] In some embodiments, the second information may be a DCI. The network device may instruct the terminal, via the DCI, to send a beam report to the network device when a trigger condition is met. After receiving the DCI, the terminal sends the beam report to the network device when the trigger condition is met.

[0198] In some embodiments, the name of the second information is not limited, and it can be, for example, "activation information", "instruction information", etc.

[0199] It can be understood that the various embodiments of the present disclosure can be implemented in any combination, and step S2103 is optional, that is, after determining the trigger condition, the terminal can directly respond to the satisfaction of the trigger condition and send a beam report to the network device without receiving the second information and then responding to the satisfaction of the trigger condition and sending a beam report to the network device, thereby omitting step S2103.

[0200] Step S2104 , the network device 102 sends third information to the terminal 101 .

[0201] In some embodiments, the terminal 101 receives third information sent by the network device 102 .

[0202] In some embodiments, the third information is used to indicate the number of beams in the beam report. That is, the network device can indicate to the terminal through the third information how many beams are included in the reported beam report.

[0203] In some embodiments, after receiving the third information, the terminal may report a corresponding number of beams in the beam report based on the indication of the third information.

[0204] In some embodiments, the name of the third information is not limited, and it can be, for example, "instruction information", "configuration information", etc.

[0205] It can be understood that the various embodiments of the present disclosure can be implemented in any combination, and step S2104 is optional, that is, the terminal can determine the number of beams in the beam report based on the indication of the third information, or determine the number of beams in the beam report by other means, thereby omitting step S2104.

[0206] Step S2105: When the trigger condition is met, the terminal 101 sends a beam report to the network device 102.

[0207] In some embodiments, the network device 102 receives a beam report sent by the terminal 101, where the beam report is sent when a trigger condition is met.

[0208] In some embodiments, the beam report may be sent based on at least one of: PUCCH; configured grant physical uplink shared channel (CG PUSCH); dynamic grant physical uplink shared channel (DG PUSCH); uplink control information (UCI); and MAC CE.

[0209] Optionally, the terminal may send a beam report via PUCCH.

[0210] Optionally, the terminal may send a beam report via a PUSCH, where the PUSCH may be, for example, a CG PUSCH or a DG PUSCH.

[0211] Optionally, the terminal may send a beam report via UCI.

[0212] Optionally, the terminal may send a beam report via MAC CE.

[0213] In some embodiments, the beam report includes at least one of the following: a reference signal resource identifier; L1-RSRP; L1-SINR; an event identifier; an indication of the maximum number of SRS ports supported; and maximum permissible exposure (MPE) information.

[0214] Optionally, the beam report may include a reference signal resource identifier to inform the network device of the reference signal resource or reference signal resource set used when measuring the beam. The reference signal resource identifier may include at least one of the following: synchronization signal and PBCH block (SSB) indication information; and channel state information reference signal identity (CSI-RS ID).

[0215] Optionally, the beam report may include L1-RSRP. That is, the beam report may include a measurement result of the beam. The measurement result is L1-RSRP.

[0216] Optionally, the beam report may include L1-SINR. That is, the beam report may include a measurement result of the beam. The measurement result is L1-SINR.

[0217] Optionally, the beam report may include an event identifier. The event identifier is used to identify an event. Specifically, the beam report may include the identifier of the event in the triggering condition that triggered the sending of the beam report. For example, if the triggering condition for sending the beam report is that the beam measurement results meet the same event X N1 times in a row, the identifier of this same event X may be included in the beam report.

[0218] Optionally, the beam report may include indication information corresponding to the maximum number of supported SRS ports. The maximum number of supported SRS ports may determine beamforming, and thus the beam report may include indication information corresponding to the maximum number of supported SRS ports.

[0219] Optionally, the beam report can include the MPE. The MPE is the maximum exposure level of radio frequency electromagnetic fields to which humans or animals may be exposed within a specific frequency range. The MPE is typically used to assess the potential health impacts of radio equipment or communication systems. Including the MPE in the beam report allows network equipment to assess the potential health impacts of radio equipment or communication systems.

[0220] In some embodiments, the MPE information includes at least one of the following: a power headroom value corresponding to the reference signal resource; a power backoff value corresponding to the reference signal resource, the power backoff being used to satisfy the MPE; and a difference between the power headroom value and the power backoff value.

[0221] Optionally, the MPE information may include a power headroom value corresponding to the reference signal resource. The power headroom refers to the difference from the maximum transmit power, that is, how much the terminal can increase its transmit power.

[0222] Optionally, the MPE information may include a power backoff value corresponding to the reference signal resource. The power backoff value is used to meet the MPE. That is, through power backoff, the transmit power value is reduced to meet the MPE, that is, to reach a radiation level that does not affect human health.

[0223] Optionally, the MPE information may include a difference between a power headroom value and a power backoff value corresponding to the reference signal.

[0224] In some embodiments, the number of beams in the beam report can be determined in the following ways: the terminal determines based on a fixed value specified in the protocol; the terminal determines based on third information sent by the network device, where the third information is used to indicate the number; the terminal determines by itself.

[0225] Optionally, the number of beams in the beam report may be determined by the terminal based on a fixed value specified in the protocol.

[0226] Optionally, the number of beams in the beam report may be determined by third information sent by the network device. The network device may send third information to the terminal to indicate the number of beams in the beam report.

[0227] Optionally, the number of beams in the beam report may be determined by the terminal itself. For example, the number of beams reported in the beam report may be determined based on the quality and quantity of the beams in actual situations.

[0228] In some embodiments, if the number of beams in the beam report is determined by the terminal itself, the terminal may include the number in the beam report so as to inform the network device of the number.

[0308] a) Define a counter. When the conditions defined by an event are met for the first time, the counter is incremented by 1. If the conditions defined by the same event are met N times in a row, the trigger event is determined to have been met. That is, when the counter is incremented to N1, the beam report is triggered.

[0309] b) Define a timer. When the conditions of an event definition are met for the first time, the timer starts counting down. When the timer ends, if there is no unsatisfied condition of the event definition, it is determined that the trigger event is met and the beam report is sent.

[0310] c) A counter and timer are combined. When the conditions defined by an event are first met, the timer begins counting down. At the end of the timer, if the conditions defined by the event are met N2 times or the number of times the conditions defined by the event are not met is less than N3, or the proportion is less than N%, then the trigger event is determined to have been met, triggering the transmission of the beam report. N% can be a second threshold.

[0311] d) The measurement results, L1-RSRP or L1-SINR, are filtered, including L1 filtering and / or L3 filtering. The filtered results are used for event detection. The filtering can define a window value, that is, multiple measurement results within the window are filtered.

[0312] i. L1 filtering can be linear averaging or terminal-based implementation;

[0313] ii. L3 filtering is (1-a)P1+a*P2, where P1 is the result of multiple filtering passes, P2 is the result of the most recent L1 filtering pass, and a is a parameter less than 1 and greater than 0. P1 can be the result of L3 filtering.

[0314] In some embodiments, the window may be a second duration.

[0315] In some embodiments, the triggering event includes at least one of the following:

[0316] a) The first beam is below a threshold; where the first beam is defined as: the best beam in the last report, the beam most recently indicated by the base station, all beams in the last report, or the worst beam in the last report. For example, the threshold may be a third threshold.

[0317] b) The second beam is above a threshold; wherein the second beam is defined as: a non-optimal beam in the last report, a beam other than the beam included in the last report, or a beam other than the beam most recently indicated by the base station. For example, the threshold may be a fourth threshold.

[0318] c) The second beam is higher than the first beam by an offset; wherein the first beam and the second beam are defined as above. For example, the offset may be a fifth threshold.

[0319] In some embodiments, the indication information includes at least one of the following:

[0320] a) RRC signaling configures the trigger event, as well as the threshold value, offset, etc. related to the trigger event. The terminal then reports when the trigger event is met;

[0321] b) or RRC signaling configuration trigger event, as well as related thresholds, offsets, etc., and further use MAC CE activation or DCI indication, the terminal will report when the trigger event is met.

[0322] In some embodiments, an association relationship may also be configured during RRC configuration, such as a trigger event and a related threshold or offset with a reference signal resource or resource set, including CMR and / or IMR. The reference signal resource may be a reference signal resource that is sent periodically, semi-persistently, or aperiodically, and associated with the reported measurement quantity L1-RSRP or L1-SINR. The reporting type, semi-persistent, or aperiodic transmission report, is used for simultaneous uplink transmission and / or simultaneous downlink reception. This may be a base station configuration, or the terminal may report which type itself, as well as an associated identity (ID), and then the MAC CE or DCI may directly activate or indicate the ID. If indicated by DCI, the channel state information request (CSI request) field may be directly reused or extended.

[0323] In some embodiments, the reporting resources of the beam report include:

[0324] a) PUCCH, or CG / DG PUSCH

[0325] b) Based on UCI or MAC CE reporting

[0326] c) The number of reported beams is fixed or configured by the base station or determined by the terminal and indicated in the beam report.
