[0029] The embodiments of the present disclosure provide a communication method, a terminal, a network device and a storage medium.
[0030] In a first aspect, the embodiments of the present disclosure provide a communication method, which includes: a terminal satisfying a trigger condition, sending a first report to a network device, the first report including information of a first beam in the trigger condition and / or information of a second beam in the trigger condition.
[0031] In the above embodiments, the terminal sends the first report to the network device when the condition is satisfied, and the first report can include the information of the first beam in the trigger condition and / or the information of the second beam, so as to improve the communication efficiency by designing the first report to include the information of the first beam and / or the information of the second beam.
[0032] In some optional embodiments of the first aspect, the information of the first beam includes at least one of: an ID corresponding to the first beam; and / or a measurement result of a reference signal resource corresponding to the first beam, and / or the information of the second beam includes at least one of: an ID corresponding to the second beam; and / or a measurement result of a reference signal resource corresponding to the second beam.
[0033] In the above embodiments, the information of the first beam can include an ID corresponding to the first beam and a measurement result of a reference signal resource, and the information of the second beam can include an ID corresponding to the second beam and a measurement result of a reference signal resource, so as to improve communication efficiency.
[0034] In some optional embodiments of the first aspect, the ID corresponding to the first beam includes at least one of the following: an ID of a reference signal resource corresponding to the first beam; and / or an ID of a transmission configuration indication state (TCI state) corresponding to the first beam, and / or the ID corresponding to the second beam includes at least one of the following: an ID of a reference signal resource corresponding to the second beam; and / or an ID of a transmission configuration indication state (TCI state) corresponding to the second beam.
[0035] In the above embodiments, the ID can be an ID of a reference signal resource or an ID of a TCI state. For example, if the network device configures an ID of a reference signal resource, the terminal can report the ID of the reference signal resource, so as to be associated with the measurement result of the reference signal resource, so that the network device knows the quality of the corresponding beam. If the network device does not configure the ID of the reference signal resource and indicates a TCI state, the ID of the TCI state can be reported, and the ID of the TCI state and the measurement result of the reference signal can also have a corresponding relationship, so that the network device knows the quality of the corresponding beam.
[0036] In some optional embodiments of the first aspect, the first report includes N IDs and measurement results of N reference signal resources, where N is a positive integer greater than 1.
[0037] In the above embodiments, the first report can include N IDs and measurement results of N reference signal resources, that is, the number of IDs and the number of measurement results can be consistent, so that the network device knows each ID and its corresponding measurement result, and improves efficiency.
[0038] In some optional embodiments of the first aspect, the N IDs include the ID corresponding to the second beam, or the N IDs include the ID corresponding to the second beam and the ID corresponding to the first beam.
[0039] In the above embodiment, the N IDs can only include the ID of the second beam, i.e., the terminal can only report the ID of the second beam in the first report. For example, when the trigger condition is that the measurement result of the second beam is greater than a certain threshold, in this case, the terminal can only report the ID and the measurement result of the second beam, and does not report the measurement result of the first beam, so as to save resources. Or the N IDs can include the ID of the second beam and the ID of the first beam, i.e., the terminal can report the IDs of the first beam and the second beam in the first report. For example, the trigger condition is that the difference between the measurement result of the second beam and the first beam is greater than a certain threshold, in this case, the terminal can report the ID and the measurement result of the first beam, and the ID and the measurement result of the second beam, so as to facilitate the network device to know the quality of the first beam and the second beam in the trigger condition.

[0043] In the above embodiment, the terminal can report the ID of the second beam, the network device knows the ID of the first beam, and therefore does not report the ID of the first beam, so as to save resources.

[0045] In the above embodiment, whether the first report includes the information of the first beam can be indicated by the first indication field, if it is indicated to include, the ID of the first beam does not need to be reported, and only the measurement result needs to be reported, so as to save resources.
[0046] In some optional embodiments of the first aspect, the first report is preconfigured with a specified position field, and the specified position field is used to report the information of the first beam.
[0047] In the above embodiments, information about the first beam can be reported through a domain at a specified location.

[0051] In the above embodiments, the measurement results in the first report can be reported in the form of absolute value and relative value. That is, the measurement result with the largest value is reported in absolute value, and the remaining measurement results are reported in relative value. The relative value occupies fewer bits than the absolute value, so as to save resources.

[0098] In some embodiments, the apparatus and device can be interpreted as physical or virtual, and its name is not limited to the name described in the embodiments, and in some cases can also be understood as "equipment", "device", "circuit", "network element", "node", "function", "unit", "section", "system", "network", "chip", "chip system", "entity", "subject" and the like.
[0099] In some embodiments, "network" can be interpreted as an apparatus included in the network, such as an access network device, a core network device, and the like.
[0100] In some embodiments, an “access network device (AN device)” can also be referred to as a “radio access network device (RAN device),” a “base station (BS),” a “radio base station,” a “fixed station,” and in some embodiments can also be understood as a “node,” an “access point,” a “transmission point (TP),” a “reception point (RP),” a “transmission / reception point (TRP),” a “panel,” an “antenna panel,” an “antenna array,” a “cell,” a “macro cell,” a “small cell,” a “femto cell,” a “pico cell,” a “sector,” a “cell group,” a “serving cell,” a “carrier,” a “component carrier,” a “bandwidth part (BWP),” and the like.
[0101] In some embodiments, a "terminal" or "terminal device" can be referred to as a "user equipment" (UE), a "user terminal," a "mobile station" (MS), a "mobile terminal" (MT), a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communication device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client, and / or the like.
[0102] In some embodiments, data, information and / or the like can be obtained in compliance with laws and regulations of the country in which the data, information and / or the like is obtained.
[0103] In some embodiments, data, information and / or the like can be obtained after consent is given by a user.
[0104] Further, each element, each row, or each column in a table of embodiments of the present disclosure can be implemented as an independent embodiment, and a combination of any element, any row, or any column can be implemented as an independent embodiment.
[0105] In NR, especially when the communication frequency band is in FR2 (above 7 GHz), due to fast attenuation of high frequency channels, in order to ensure coverage, beam-based transmission and reception need to be used. Currently, the cases considered are all base station configurations of periodic, semi-persistent or aperiodic beam measurement reports.
[0106] But in fact, the terminal can learn the beam quality change in time, and the period length of the periodic reporting configured by the base station, or the timing of the non-periodic reporting configured by the base station, is not necessarily the most appropriate. If the period is too short, the best K beams reported twice may be the same, without change, wasting signaling. If the period is too long, the beam may have changed, but it is not time to report, affecting communication quality. And the same for non-periodic reporting, the timing of the terminal reporting triggered by the base station may be too early or too late, not the most appropriate timing.
[0107] Therefore, how to design the format of the beam report is a problem to be solved.
[0108] In some embodiments, the beam report includes at most 4 reference signal identities (RS IDs) and the corresponding layer 1 reference signal received power (L1-RSRP) or layer 1 signal to interference and noise ratio (L1-SINR) of each RS ID, where the strongest L1-RSRP / L1-SINR is placed at the front, using 7 bits to feed back the absolute value; the other L1-RSRP / L1-SINR feeds back the relative difference with the strongest L1-RSRP / L1-SINR, and each difference corresponds to 4 bits.
[0109] There can be many cases for event triggered beam reporting, the first is only new beam, which can also be called candidate beam or adjacent beam.

[0121] FIG. 2 is an interaction diagram illustrating a communication method according to an embodiment of the present disclosure. As shown in FIG. 2, the embodiment of the present disclosure relates to a communication method for the communication system 100, and the above method comprises:
[0122] In step S2101, the network device 102 sends first information to the terminal 101.
[0123] In some embodiments, the terminal 101 receives first information sent by the network device. The first information is used to instruct the terminal to report information of the first beam in a first report. The first report can also be referred to as a beam report. The terminal can send the first report to the network device when a triggering condition is met.
[0124] In some embodiments, the first information can be configured by Radio Resource Control (RRC).
[0125] In some embodiments, the first report includes information of the first beam in the triggering condition and / or information of the second beam in the triggering condition. That is, the first report can not include information of the first beam. When the terminal receives the first information sent by the network device, the information of the first beam is reported according to the first information, that is, in this case, the first report includes the information of the first beam. It can be understood that if the network device 102 does not send the first information to the terminal 101, or the terminal 101 does not receive the first information, the terminal can determine whether the first report includes the information of the first beam by itself. Or, even if the terminal receives the first information, it can also determine whether to report the information of the first beam according to the actual situation. If the terminal receives the first information but does not report the information of the first beam, it can inform the network device that the first report does not include the information of the first beam, and can also inform the network device the reason why the first report does not include the information of the first beam.
[0126] In some embodiments, the first beam includes a current beam, which can also be referred to as a serving beam, or a first beam set, but is not limited thereto. The first beam may, for example, be a beam being used. For another example, the first beam can be a beam indicated by the network device last time (indicated TCI state), or a best beam in the last beam report, or all beams in the last beam report, or a worst beam in the last beam report, without limitation of the present disclosure. The second beam includes a new beam, which can also be referred to as a candidate beam or a target beam or a neighboring beam, but is not limited thereto. The second beam may, for example, be a beam other than the first beam, such as a non-best beam in the last beam report, a beam other than the beam included in the last beam report, or a beam other than the beam indicated by the network device last time.
[0127] In some embodiments, the beam can also be referred to as a spatial reception parameter, a quasi co-location (QCL) type D, a spatial setting, a spatial reception filter, a spatial transmission filter, a spatial domain filter, a transmission configuration indicator (TCI) state, a joint TCI state, a downlink TCI state (DL TCI state), an uplink TCI state (DL TCI state), a unified TCI state, a common TCI state, and spatial relation information, etc. The beam can be replaced by any of the above.
[0128] In some embodiments, the name of the first information is not limited, which can be, for example, “configuration information”, “indication information”, etc.
[0129] It can be understood that step S2101 is optional.
[0130] In step S2102, the network device 102 sends second information to the terminal 101.
[0131] In some embodiments, the terminal 101 receives the second information sent by the network device 102, and the second information is used to configure the reference signal resource corresponding to the second beam.
[0132] In some embodiments, the first report includes information of the second beam in the triggering condition. The terminal can receive the reference signal resource corresponding to the second beam sent by the network device. The terminal measures the measurement result of the reference signal resource corresponding to the second beam based on the reference signal resource of the second beam, i.e., obtains the information of the second beam.
[0133] In some embodiments, the name of the second information is not limited, which can be, for example, “configuration information”.
[0134] It can be understood that step S2102 is optional.
[0135] At step S2103, the terminal 101 satisfies the triggering condition, and sends the first report to the network device 102.
[0136] In some embodiments, the terminal 101 can send the first report to the network device 102 when the triggering condition is satisfied. In this case, the first report includes the information about the first beam in the triggering condition and / or the information about the second beam in the triggering condition.
[0137] In some embodiments, the triggering condition can also be referred to as a triggering event, or an event (event) or a condition (condition).
[0138] In some embodiments, the triggering condition includes at least one of the following: the quality of the first beam is less than or equal to a first threshold value; the quality of the second beam is greater than or equal to a second threshold value; the difference between the quality of the first beam and the quality of the second beam is greater than or equal to a third threshold value. In the case that the difference between the quality of the first beam and the quality of the second beam is greater than or equal to the third threshold value, the quality of the second beam is greater than the quality of the first beam, i.e., the quality of the second beam is higher than the quality of the first beam by the third threshold value.
[0139] In some embodiments, the quality of the beam can be the L1-RSRP of the reference signal resource corresponding to the beam, or can be the layer 1 signal to interference plus noise ratio (L1-SINR) of the reference signal resource corresponding to the beam, or can be the uplink transmission power. It can be understood that the greater the L1-RSRP value of the reference signal resource corresponding to the beam, the higher the quality of the beam. Correspondingly, the greater the L1-SINR value, the higher the quality of the beam. The greater the uplink transmission power, the higher the quality of the beam.
[0140] In some embodiments, when the monitored first beam is a joint or uplink (UL) TCI state, and / or the monitored second beam will be used for a joint or UL TCI state, the quality of the beam can be the uplink transmission power.
[0141] In some embodiments, even if the trigger condition satisfied by the terminal only includes the first beam, the terminal can report the information of the second beam in the first report. Correspondingly, even if the trigger condition satisfied by the terminal only includes the second beam, the terminal can report the information of the first beam in the first report. For example, the terminal can send the first report to the network device when the quality of the first beam is less than or equal to the first threshold value, and the first report can include the information of the first beam, the information of the second beam, or both the information of the first beam and the information of the second beam. For another example, the terminal can send the first report to the network device when the quality of the second beam is greater than or equal to the second threshold value, and the first report can include the information of the second beam, the information of the first beam, or both the information of the first beam and the information of the second beam.
[0142] In some embodiments, the information of the first beam includes at least one of: an ID corresponding to the first beam; a measurement result of a reference signal resource corresponding to the first beam. The ID corresponding to the first beam includes at least one of: an ID of the reference signal resource corresponding to the first beam; an ID of a Transmission Configuration Indicator state (TCI state) corresponding to the first beam.
[0143] In some embodiments, the information of the second beam includes at least one of: an ID corresponding to the second beam; a measurement result of a reference signal resource corresponding to the second beam. The ID corresponding to the second beam includes at least one of: an ID of the reference signal resource corresponding to the second beam; an ID of a TCI state corresponding to the second beam.
[0144] In some embodiments, the measurement result of the reference signal resource includes at least one of: L1-RSRP; L1-SINR.
[0145] In some embodiments, the first report includes N IDs and measurement results of N reference signal resources, N being a positive integer greater than 1.
[0146] Optionally, the N IDs include an ID corresponding to the second beam. For example, the N IDs can be N IDs of reference signal resources corresponding to the second beam, or can be N IDs of TCI states corresponding to the second beam. Correspondingly, the measurement results of the N reference signal resources can be measurement results of N reference signal resources corresponding to the second beam. That is, the first report can include the information of the second beam.
[0147] Optionally, the N IDs include an ID corresponding to the first beam and an ID corresponding to the second beam. For example, the N IDs can be the IDs of the M first beams and the IDs of the N-M second beams. Correspondingly, the measurement results of the N reference signal resources can be the measurement results of the reference signal resources corresponding to the M first beams and the measurement results of the reference signal resources corresponding to the N-M second beams. Wherein, M is a positive integer greater than 0. That is, the first report can include the information of the first beam and the information of the second beam.
[0148] In some embodiments, among the plurality of reference signal measurement results in the first report, the measurement result with the largest value can be at the front of all measurement results. And the ID corresponding to the measurement result with the largest value is also at the front of all IDs in the first report.
[0149] In some embodiments, among the plurality of reference signal measurement results in the first report, the measurement result with the largest value can report an absolute value, and the remaining measurement results can report relative values. The relative value refers to the difference between the measurement result with the largest value. The measurement result with the largest value is represented by a first number of bits, and the relative values corresponding to the remaining measurement results are represented by a second number of bits. For example, the absolute value corresponding to the measurement result with the largest value can be represented by a first number of bits. For example, the first number can be 7, and the second number can be 4, but is not limited thereto.
[0150] In some embodiments, one ID in the N IDs has a corresponding relationship with one measurement result in the measurement results of the N reference signal resources.
[0151] In some embodiments, the reference signal resource can be a channel state information-reference signal (CSI-RS) resource, a synchronization signal block (SSB) resource, or a CSI-RS resource configured with tracking reference signal (trs) information.
[0152] In some embodiments, taking the ID of a CSI-RS resource (referred to as CRI) or the ID of an SSB resource (referred to as SSBRI) as an example, and taking the measurement result of a reference signal resource as an example of L1-RSRP, the mapping order of the ID and the measurement result of the reference signal resource in the first report is exemplarily introduced, as shown in Table 1.
[0153] Table 1
[0154] CRI or SSBRI#1 represents a CRI or SSBRI numbered #1. Correspondingly, CRI or SSBRI#2 represents a CRI or SSBRI numbered #2, which is not described in detail in the present disclosure. RSRP#1 represents a RSRP numbered #1, which corresponds to CRI or SSBRI#1. RSRP differential (Differential RSRP)#2 represents the difference between the second RSRP (RSRP#2) and the first RSRP (RSRP#1). That is, the first RSRP exists in the first report in the form of an absolute value (RSRP#1), and the second RSRP exists in the first report in the form of a relative value (Differential RSRP#2), which corresponds to CRI or SSBRI#2. Correspondingly, the third RSRP also exists in the first report in the form of a relative value (Differential RSRP#3). Differential RSRP#3 corresponds to CRI or SSBRI#3. Among them, the strongest L1-RSRP (RSRP#1) represents the L1-RSRP with the largest value, and the field corresponding thereto can be at the front of the fields corresponding to all RSRPs. Correspondingly, the ID corresponding to the strongest L1-RSRP (RSRP#1), that is, CRI or SSBRI#1, can be at the front of the fields corresponding to all IDs.
[0155] In some embodiments, the mapping order of the IDs and the measurement results of the reference signal resources in the first report is exemplarily introduced by taking the TCI state ID as an example and taking the L1-RSRP as an example of the measurement result of the reference signal resource, as shown in Table 2.
[0156] Table 2
[0157] Among them, TCI state#1 represents a TCI state ID numbered #1, and the parameters in Table 2 can refer to the introduction part of Table 1, which is not described in detail herein.
[0158] In some embodiments, the first report includes N-M IDs and N measurement results of reference signal resources. N is a positive integer greater than 1, and M is a positive integer greater than 0.
[0159] In some embodiments, the N-M IDs include IDs corresponding to the second beams, and the measurement results of the N reference signal resources include measurement results of reference signal resources corresponding to the M first beams and measurement results of reference signal resources corresponding to the N-M second beams. For example, the network device knows the IDs of the first beams, and thus for the M first beams, the first report only includes the measurement results of the reference signal resources corresponding to the first beams, and does not include the IDs corresponding to the first beams.
[0160] In some embodiments, one of the N-M IDs has a corresponding relationship with one of the measurement results of the reference signal resources corresponding to the N-M second beams.
[0161] In some embodiments, the information of the first beams can be reported in a specified position domain, and the specified position domain includes a domain for reporting measurement results at a specified position. The terminal reports the measurement results of the first beams in the specified position domain. The network device can determine the IDs of the first beams corresponding to the measurement results reported in the specified position domain by itself. For example, when the terminal reports N measurement results, M specified position domains report the measurement results, but there are no corresponding IDs. The M measurement results correspond to the IDs of the first beams.
[0162] In some embodiments, if the trigger condition is that the difference between the quality of the first beam and the quality of the second beam is greater than or equal to a third threshold value, the L1-RSRP with the largest value does not correspond to the first beam, and the specified position domain corresponding to the measurement result (Differential RSRP#4) of the first beam can be at the end of all RSRP corresponding domains or after the domain corresponding to the second strongest L1-RSRP.
[0163] In some embodiments, taking the ID of a CSI-RS resource (CRI) or the ID of an SSB resource (SSBRI) as an example, and taking the measurement result of a reference signal resource as an example, the L1-RSRP, the mapping order of the ID and the measurement result of the reference signal resource in the first report when the trigger condition is that the difference between the quality of the first beam and the quality of the second beam is greater than or equal to a third threshold value is exemplarily introduced, as shown in Table 3 (order 1) and Table 4 (order 2). Taking M equal to 1 as an example, the number of the first beams is 1, and the ID corresponding to the first beam does not need to be indicated, i.e., there is no corresponding indication domain in the first report. The specified position domain corresponding to the measurement result (Differential RSRP#4) of the first beam can be at the end of all RSRP corresponding domains, as shown in Table 3. The specified position domain corresponding to Differential RSRP#4 can also be after the domain corresponding to the second strongest L1-RSRP, as shown in Table 4.
[0164] Table 3
[0165] Table 4
[0166] In some embodiments, the ID in the first report takes TCI state ID as an example, and the measurement result of the reference signal resource takes L1-RSRP as an example. The mapping order of the ID and the measurement result of the reference signal resource in the first report is exemplarily introduced as follows: when the difference between the quality of the first beam and the quality of the second beam is greater than or equal to a third threshold value, the mapping order of the ID and the measurement result of the reference signal resource in the first report is as shown in Tables 5 and 6.
[0167] Table 5
[0168] Table 6
[0169] In some embodiments, the first report includes a first indication field, the first indication field is used to indicate that the first report includes information of the first beam, and the information of the first beam includes measurement results of reference signal resources corresponding to the M first beams; or, the first report includes a first indication field, and the first indication field is used to indicate that the first report does not include information of the first beam. For example, when the first indication field is 1, it indicates that the first report includes information of the first beam, and the first report can be reported in the manner of any one of Tables 3-6, that is, the ID information of the first beam is not required. For another example, when the first indication field is 0, it indicates that the first report does not include information of the first beam, and the first report can be reported in the manner of any one of Tables 1-2, that is, the ID of each beam needs to be included.
[0170] In some embodiments, the ID in the first report takes TCI state ID as an example, and the measurement result of the reference signal resource takes L1-RSRP as an example. The mapping order of the ID and the measurement result of the reference signal resource in the first report is exemplarily introduced as follows: when the first report includes a first indication field, the mapping order of the ID and the measurement result of the reference signal resource in the first report is as shown in Table 7.
[0171] Table 7
[0172] The first indication field in Table 7 is a 1-bit indication field, but this example is only exemplary and is not limited thereto. The first indication field can be at the front of the first report or at any specified position before the RSRP indication field of the first report, and is not limited thereto. If the first indication field indicates that the information of the first beam exists, the first report only needs to include N-M IDs, M being the number of the first beams, and at this time the terminal reports the measurement result of the reference signal resource corresponding to the first beam, and the ID corresponding to the first beam is determined by the network device. If the first indication field indicates that the information of the first beam does not exist, the first report includes N IDs, for example, the IDs corresponding to the N second beams. It can be understood that if the first indication field in the first report indicates that the information of the first beam exists, the ID of the first beam does not need to be reported in the first report, and only the measurement result of the reference signal resource corresponding to the first beam needs to be reported, so as to save bits and resources. If the first indication field in the first report indicates that the information of the first beam does not exist, the network device knows that the first report includes the IDs of the second beams and the measurement results of the reference signal resources corresponding to the second beams, and the IDs of the N second beams and the measurement results of the reference signal resources corresponding to the N second beams are one-to-one corresponding.
[0173] In some embodiments, the first report further includes at least one of the following: a capability index; a power margin; a maximum permissible exposure MPE; an uplink transmission power; an ID of a triggering condition, but is not limited thereto.
[0174] The communication method related to the embodiments of the present disclosure can include at least one of steps S2101-S2103. Steps S2101-S2103 can be implemented as separate embodiments, and under non-contradictory conditions, each embodiment can be arbitrarily combined and adjusted in order. For example, step S2103 can be implemented as a separate embodiment, but is not limited thereto.
[0175] In some embodiments, steps S2101 and S2102 are optional, and one or more of these steps can be omitted or replaced in different embodiments.
[0176] In some embodiments, other optional implementations described before or after the corresponding description of FIG. 2 can be referred to.

[0235] The present disclosure provides a communication method, which is as follows:
[0236] In some embodiments, the terminal determines a first reference signal resource, the first reference signal resource is used to determine a first beam or a new beam in an event (may also be referred to as a triggering condition), and the terminal sends a first report when the event triggering condition is met based on the first reference signal resource and the event.
[0237] In some embodiments, the beam can be referred to as beam, spatial Rx parameter, QCL (quasi-co location) Type D, spatial setting, spatial reception filter, spatial transmission filter, spatial domain filter, TCI state, indicated TCI state, joint TCI state, DL TCI state, UL TCI state, unified TCI state, common TCI state, spatialrelationinfo, etc.
[0238] In some embodiments, the first report is also referred to as a beam report.
[0239] In some embodiments, the first report includes at least one of the following: current beam related information; new beam related information.
[0240] In some embodiments, the current beam related information; the current beam related information includes at least one of the following: RS ID, L1-RSRP, or TCI state ID corresponding to the current beam. The RS includes SSB, CSI-RS or CSI-RS configured with (tracking RS, trs) information. The new beam related information includes at least one of the following: RS ID, L1-RSRP (or L1-SINR), or TCI state ID corresponding to the new beam.
[0241] In some embodiments, the first report format includes at least one of the following:
[0242] 1), N RS IDs + N L1-RSRPs:
[0243] The strongest L1-RSRP is reported in absolute value, and the other L1-RSRPs are reported in relative value to the strongest L1-RSRP. For example, the strongest L1-RSRP is indicated by 7 bits, and the other L1-RSRPs are indicated by 4 bits. In this case, one of the N RSs can be associated with the current beam, or none of the N RSs can be associated with the current beam. For example, the RRC configuration can include the RS ID associated with the current beam.
[0244] In some embodiments, the mapping order is as shown in Table 1 in the above embodiment.
[0245] 2), N TCI state IDs + N L1-RSRPs:
[0246] The strongest L1-RSRP is reported in absolute value, and the other L1-RSRPs are reported in relative value to the strongest L1-RSRP. For example, the strongest L1-RSRP is indicated by 7 bits, and the other L1-RSRPs are indicated by 4 bits. In this case, one of the N TCI states can be associated with the current beam, or none of the N TCI states can be associated with the current beam. For example, the RRC configuration can include the RS ID associated with the current beam.
[0247] In some embodiments, the mapping order is as shown in Table 2 in the above embodiment.
[0248] 3), N-1 RS IDs + N L1-RSRPs (N can be different in each method).
[0249] Here, one RS ID is missing because the RS ID corresponds to the RS ID of the current beam.
[0250] The strongest L1-RSRP is reported in absolute value, and the other L1-RSRPs are reported in relative value to the strongest L1-RSRP. For example, the strongest L1-RSRP is indicated by 7 bits, and the other L1-RSRPs are indicated by 4 bits. In this case, for the beam report triggered by the event (for example, the trigger condition in the above embodiment) that the new beam is higher than the current beam by a threshold value, the strongest L1-RSRP does not correspond to the current beam, so the reporting order can be Table 3 (order 1) or Table 4 (order 2) in the above embodiment.
[0251] 4), N-1 TCI state IDs + N L1-RSRPs:
[0252] Here is one less TCI state ID, because this TCI state ID corresponds to the TCI state ID of the current beam.
[0253] Among them, the strongest L1-RSRP is reported in absolute value, and the other L1-RSRP is reported in relative value to the strongest L1-RSRP, such as the largest L1-RSRP is indicated by 7-bit, and the other relative value is indicated by 4-bit. In this case, there may be one of the N TCI states associated with the current beam, or there may be no TCI state associated with the current beam. In this case, for the beam report triggered by the event: the new beam is higher than the current beam by a threshold, the largest L1-RSRP does not correspond to the current beam, so the reporting order can be Table 5 (order 1) or Table 6 (order 2).
[0254] In some embodiments, 1) and 3) can be dynamically switched, so a 1-bit can be introduced to specifically indicate whether the current beam is included. If the current beam is included, the mode of 3) is adopted, and if the current beam is not included, the mode of 1) is adopted.
[0255] In some embodiments, the mapping order of 1) or 3) is as shown in Table 7 of the above embodiment, which is only one example, and other examples are the same.
[0256] In some embodiments, one L1-RSRP, the L1-RSRP corresponding to the current beam, is reported in absolute value.
[0257] In some embodiments, the first report further includes at least one of the following:
[0258] Capability index (Capability index): the maximum number of supported sounding reference signal ports (the maximum number of supported SRS port);
[0259] Power headroom (Power headroom);

[0261] Uplink transmission power: e.g. power headroom - power backoff
[0262] Trigger condition ID (i.e. Event ID).
[0263] In some embodiments, the first beam, current beam, can also be referred to as serving beam, or simply as first beam or first beam set.
[0264] In some embodiments, the event includes at least one of:
[0265] The first beam quality is lower than a threshold, where the quality can be L1-RSRP, L1-SINR, or the quality can also be uplink transmission power (when the monitored first beam is joint or UL TCI state, and / or the monitored second beam is intended to be used for joint or UL TCI state);
[0266] The second beam quality is higher than a threshold (the second beam can also be referred to as new beam, target beam, etc.);
