Abstract
Description
Technical Field

[0002] In the beam management mechanism in related technologies, beam quality is usually detected through beam measurement and reporting triggered by a network-side device, and the network-side device then performs beam configuration, activation, and indication based on the beam measurement results reported by the terminal.

[0056] For ease of understanding, some content related to the embodiments of this application is described below:
[0057] Regarding beam measurement
[0058] The analog beamforming is transmitted over the full bandwidth, and each element in each polarization direction on the panel of each high-frequency antenna array can only transmit the analog beam in a time-division multiplexing manner. The beamforming weights of the analog beam are achieved by adjusting the parameters of devices such as the radio frequency front-end phase shifters.
[0059] Currently in the academic and industrial communities, the polling method is usually used for training the analog beamforming vectors, that is, the elements in each polarization direction of each antenna panel sequentially transmit training signals (i.e., candidate beamforming vectors) at the agreed time in a time-division multiplexing manner. After measurement, the terminal feeds back a beam report for the network side to use this training signal to implement analog beam transmission during the next service transmission.
[0060] In the current related technologies, only beam measurements are supported through the Channel State Information-Reference Signal (CSI-RS) or the Synchronization Signal and PBCH block (or Synchronization Signal Block) (SSB). Among them, there are only 1 to 2 ports for the CSI-RS used for beam measurement. Among them, the SSB is a periodic reference signal, while the CSI-RS used for beam measurement can be periodic, semi-persistent or aperiodic.
[0061] The beam measurement is divided into layer 1 (L1) beam measurement and layer 3 (L3) beam measurement. Among them, the L1 beam measurement in protocol versions Release 15 and 16 is limited to the serving cell. Among them, Release 15 only supports the L1 Reference Signal Received Power (RSRP) measurement, and Release 16 introduces the L1 Signal to Interference plus Noise Ratio (SINR), taking into account the inter-cell interference or the interference between users in the beam measurement. Under the cross-cell beam management and cross-cell multi-transmit receive point project in protocol version Release 17, the L1 beam measurement of the neighboring cell that is co-frequency and synchronized with the current serving cell is supported. Under the mobile enhancement project in protocol version Release 18, the L1 beam measurement of the asynchronous and different-frequency neighboring cell is supported. Currently, both only support the L1-RSRP measurement based on the SSB. Based on the reporting mechanism triggered by the network-side device, after the terminal performs the L1 beam measurement according to the measurement resources configured by the network-side device, it selects the beam to report according to the measurement results.
[0062] Regarding beam reporting
[0063] The reported measurement quantities for L1 beam reporting triggered by network-side devices supported in the current protocol are L1-RSRP / L1 reference signal received quality (RSRQ) / L1-SINR. The beam reporting methods include two types: group-based and non-group-based. For non-group-based beam reporting, according to the reported measurement quantities, the terminal selects up to 4 beams for reporting from all the measurement resources configured by the network side and associated with the L1 beam report. For group-based beam reporting, in Release 15 / 16, the terminal selects a pair of beams that can be received by the UE simultaneously for reporting according to the reported measurement quantities.
[0064] In the existing protocol, if the report quantity field in the high-layer parameter CSI report configuration (CSI Report Config) is configured as "cri-RSRP" or "cri-SINR" or "ssb-Index-SINR" or "ssb-Index-RSRP", it indicates that the current CSI report is a beam report. And when the group-based beam reporting field is enabled ("enabled"), the UE can only report a pair of beams: including two channel measurement resource (CMR) identifiers and their corresponding L1-RSRP / L1-SINR values, where the above CMR identifiers include channel state information-reference signal resource indicator (CSI-RS ResourceIndicator, CRI) or SSB resource indicator (SSB resource indicator, SSBRI). When the group-based beam reporting field is disabled ("disabled"), the UE may report the CMR identifiers corresponding to 4 beams and their corresponding L1-RSRP. When the number of reported beams is greater than 1, for the L1-RSRP / L1-SINR values other than the maximum value of L1-RSRP / L1-SINR, they are reported in a differential manner with the maximum value. The specific uplink control information (UCI) mapping rules (L1-RSRP) for CSI reporting are shown in Tables 1 and 2, and L1-SINR is similar. It should be noted that the positions of CRI / SSBRI correspond to the positions of RSRP, CRI / SSBRI#1 corresponds to RSRP#1, and RSRP#1 is the maximum value among the 4 RSRPs.
[0065] Table 1 UCI mapping order for L1 beam reporting in Release 15 / 16
[0066]
[0067] Table 2 UCI Bit Overhead
[0068]
[0069] The UCI bit numbers of the above reference signal RS identification and L1-RSRP are shown in Table 2, and L1-SINR is similar. Among them, is the number of CSI-RS resources configured in a CSI-RS resource set, is the number of SSB resources configured in an SSB resource set. The current protocol supports a maximum of 64 RS resources configured in one RS (CSI-RS / SSB) set.
[0070] In the Release 17 multi-transmission and reception node project, the group-based beam reporting method is enhanced. The terminal can select up to 4 pairs of beams that can be received simultaneously from the measurement resources configured by the network for reporting, and different beams in each pair of received beams correspond to different transmission and reception nodes, so as to ensure that the network can send this pair of beams simultaneously. Its UCI mapping table is shown in Table 3.
[0071] Table 3 UCI Mapping Order of L1 Beam Reporting in Release 17
[0072]
[0073] In the Release 18 layer 1 or layer 2 triggered mobility (LTM) project, L1 reporting for handover is introduced, that is, ltm-CSI-ReportConfig. In an L1 report for handover, the terminal can report up to 4 cells at most, and each cell reports 4 beam measurement results, that is, up to 16 beams and their corresponding measurement results.
[0074] Regarding the Priority of CSI Reports
[0075] In a CSI report, when the reporting resources corresponding to multiple CSI reports overlap in the time domain, the terminal will calculate the priority evaluation values of the multiple CSI reports respectively according to the CSI report priority formula. When the priority evaluation value of a CSI report is lower, the priority of the CSI report is higher. Subsequently, the terminal sorts and performs UCI mapping according to the priority of the CSI report. When the reporting resources cannot carry the multiple CSI reports, the CSI report with a lower priority will be discarded. The CSI report priority formula is as follows:
[0076] Pri CSI (y, k, c, s) = 2·N cells ·M s ·y + N cells ·M s ·k + M s ·c + s
[0077] Wherein, for the aperiodic CSI report reported on the Physical Uplink Shared Channel (PUSCH), y = 0; for the semi-persistent CSI report reported on the PUSCH, y = 1; for the semi-persistent CSI report reported on the Physical Uplink Control Channel (PUCCH), y = 2; for the CSI report reported on the PUCCH, y = 3;
[0078] For the CSI report reporting the measurement quantity as L1-RSRP or L1-SINR, k = 0; otherwise, k = 1;
[0079] c is the serving cell index associated with the CSI report;
[0080] N cells is the value of the maximum configurable serving cell number (maxNrofServingCells), a Radio Resource Control (RRC) parameter;
[0081] s is the CSI report configuration identifier (CSI-ReportConfigId);
[0082] M s is the value of the maximum configurable number of CSI report configurations (maxNrofCSI-ReportConfigurations), an RRC parameter;
[0083] The LTM report (or LTM-CSI report, or LTM CSI report, or LTM report, or LTM-CSI report) introduced in the Release 18 LTM project is used to determine the UCI sequence and resource mapping as CSI information. When resource conflicts occur, the priority of the LTM report is always higher than that of the CSI report.
[0084] Regarding the activation and indication of beams
[0085] Such as Figure 2As shown in the figure, the Transmission Configuration Indicator (TCI) state of the Physical Downlink Shared Channel (PDSCH) needs to first select at least one TCI state from the TCI state list through the Media Access Control Control Element (MAC CE) for activation. According to the annotation description, RAN1 stipulates that the TCI state carried in the MAC CE can be in the active state only 3 ms after the Physical Uplink Control Channel (PUCCH) carrying the ACK corresponding to the MAC CE for activating the TCI state. According to the RAN4 protocol, in addition to the ACK + 3 ms stipulated by RAN1, the activation delay of the TCI state also needs to add the time for waiting for an SSB for synchronization. Therefore, the activation delay of the TCI state is ACK + 3 ms + first SSB.
[0086] If the MAC CE activates more than one TCI state, the Downlink Control Information (DCI) needs to indicate one from the activated TCI states for the terminal to receive data. For DCI-based beam indication, RAN1 stipulates a beam application delay, that is, in the first slot after Y slots after the PUCCH carrying the ACK of the PDSCH scheduled by the DCI, the terminal uses the indicated TCI state to receive data. Therefore, the application delay of the TCI state is ACK + Y slots.
[0087] Regarding event-triggered measurement and reporting
[0088] In the current protocol, the measurement quantity for event-triggered measurement and reporting is the L3 measurement result, and the main purpose is to evaluate the cell quality for cell handover. The event definitions are shown in Table 4.
[0089] Table 4 Event definitions
[0090]
[0091] In Table 4, the interpretations of each parameter are as follows:
[0092] Ms: Measurement result of the serving cell, without considering any offset;
[0093] Mn: Measurement result of the neighboring cell, without considering any offset;
[0094] Ofn: Neighboring cell measurement object specific offset;
[0095] Ocn: Neighboring cell specific offset at the cell level;
[0096] Mp: Measurement result of the SpCell (primary serving cell), without considering any offset;
[0097] Ofp: Specific offset of the SpCell measurement object;
[0098] Ocp: Specific offset at the SpCell cell level;
[0099] Hys: Hysteresis parameter of the event;
[0100] Off: Offset parameter of the event;
[0101] Mi: Interference measurement result;
[0102] Thresh: Threshold.
[0103] In the existing beam management mechanism, the terminal detects the beam quality through beam measurements and reports triggered by the network-side device, and the network-side device then performs beam configuration, activation, and indication based on the beam measurement results reported by the terminal. With the development of large-scale antenna technology and the expansion of high-speed mobile scenarios, the beam width is narrow and the beam changes rapidly with movement. Especially in the FR2 (Frequency range 2) scenario, the beam management mechanism triggered by the network-side device has the following problems:
[0104] 1) If beam real-time tracking is to be ensured, frequent beam reports need to be triggered by the network-side device. Periodic beam reports will increase the overhead of uplink resources, and aperiodic beam reports will result in a large signaling overhead; since it is triggered by the network-side device, it is possible that the beams in multiple beam reports reported by the terminal are the same (for example, the terminal repeats reporting in the same state), resulting in waste of reporting resources or downlink trigger resources;
[0105] 2) For the beam of PDSCH, it often needs to go through a series of steps such as beam measurement - reporting - activation - indication to be applied. Therefore, it is possible that the beam pair used by the terminal is not the current best beam pair, thus affecting the data reception performance.
[0106] With the development of large-scale antenna technology and the expansion of high-speed mobile scenarios, the beam width is narrow and the beam changes rapidly with movement. The beam management mechanism triggered by the network has the problem of large resource overhead, and further has the problem of large beam switching delay.
[0107] The related technology already supports the beam management mechanism triggered by the UE (i.e., measurement and reporting triggered by events). However, the measurement reporting triggered by events only supports L3 measurement and is reported at the RRC layer, and cannot flexibly implement the function of UE-triggered beam management based on L1 measurement.
[0108] The following will describe in detail the beam management method, apparatus, terminal, device, and medium provided by the embodiments of the present application with reference to the accompanying drawings and through some embodiments and their application scenarios.
[0109] Refer to Figure 3 , Figure 3 which is a flowchart of a beam management method provided by an embodiment of the present application for a terminal, such as Figure 3 shown, and the method includes the following steps:
[0110] Step 301: When the terminal meets the first condition, perform a first operation;
[0111] Among them, the first condition includes at least one of the following:
[0112] There is at least one first target reference signal;
[0113] There is at least one target object, and the target object is different from the current serving object of the terminal;
[0114] The first operation includes at least one of the following:
[0115] Perform at least one of beam measurement and channel state information (CSI) measurement on a second target reference signal;
[0116] Send first target information to the network-side device, where the first target information includes at least one of relevant information of the first target reference signal, relevant information of the second target reference signal, transmission configuration indication (TCI) relevant information, and beam assistance information.
[0117] In the embodiments of the present application, the terminal meeting the first condition is used as the trigger condition for performing the beam management operation (the first operation). That is to say, the embodiments of the present application are different from the relevant mechanisms for triggering beam management in the related art. By setting the first condition, that is, the beam management is triggered only when there is a target reference signal (the first target reference signal) or a target object at the terminal, it can be understood as a terminal-triggered beam management method, which can reduce unnecessary beam reporting and thus effectively reduce the resource overhead of beam management.
[0118] In the embodiments of the present application, the reference signal (RS) can be a CSI-RS, SSB, tracking reference signal (TRS), positioning reference signal (PRS), demodulation reference signal (DMRS), etc. adopted in the art, and the embodiments of the present application do not limit this.
[0119] Optionally, the above first target reference signal and target object may be pre-configured by the network or agreed upon by a protocol. The above first target reference signal may be of the serving cell or a neighboring cell.
[0120] In the embodiments of the present application, the above second target reference signal may be understood as a target reference signal configured by the network-side device for the above terminal to perform beam measurement or CSI measurement under the condition of satisfying the first condition, which may be pre-configured by the network or agreed upon by a protocol. The above second target reference signal may be of the serving cell or a neighboring cell.
[0121] The above target object may be an object different from the current terminal service object.
[0122] Optionally, the target object includes at least one of the following:
[0123] Control Resource Set Pool Index (CoresetPoolIndex), channel group, cell, cell group, Distributed Unit (DU), Centralized Unit (CU).
[0124] In the embodiments of the present application, the above first target information may be understood as the information reported by the terminal to the network-side device when the terminal performs beam management under the condition of satisfying the first condition. Or rather, the above first target information may be understood as the beam management report information of the terminal.
[0125] The above first target information may include the relevant information of the first target reference signal, that is, when there is a first target reference signal, the terminal reports the relevant information of the above first target reference signal to the network-side device. For example, it may be at least one of the measurement result and index corresponding to the reported first target reference signal.
[0126] The above first target information may also include the relevant information of the second target reference signal. It may be that when the terminal performs relevant measurements (at least one of beam measurement and Channel State Information CSI measurement) of the second target reference signal under the condition of satisfying the first condition, the terminal sends at least one of at least part of the measurement results (for example, the measurement results that meet the preset threshold, or the best measurement results, or all the measurement results) of the second target reference signal and at least part of the indexes of the second target reference signal to the network-side device.
[0127] The above first target information may also include TCI-related information. For example, the TCI state identifier (e.g., ID), or the TCI code point. Different from the related art where the network-side device indicates the TCI-related information to the terminal, in the embodiments of the present application, the terminal may send the TCI-related information to the network-side device. It can be understood that the terminal recommends the TCI-related information (e.g., at least one of the TCI state id and the TCI codepoint) to the network-side device for signal transmission.
[0128] The above first target information may also include beam assistance information. For example, the beam change pattern, the transmit beam of the network-side device predicted by the terminal. The above beam change pattern may be the change characteristics of the beam used by the terminal in the past or the beam change characteristics obtained by the terminal through beam prediction. The above prediction by the terminal may be performed based on the measurement and observation results of the terminal within a preset time period as samples.
[0129] When the above first target information includes at least one of the relevant information of the first target reference signal and the relevant information of the second target reference signal, the terminal may report the relevant information of N third target reference signals in a non-group-based reporting manner, or report the relevant information of N groups of fourth target reference signals in a group-based reporting manner. The third target reference signal is at least one of the first target reference signal and the second target reference signal, and the fourth target reference signal is at least one of the first target reference signal and the second target reference signal. Each group of fourth target reference signals in the N groups of fourth target reference signals can be received by the terminal simultaneously. Further, the reporting manner (group-based or non-group-based) is configured by the network-side device, and the value of N is configured by the network-side device or determined by the UE.
[0130] Optionally, the reporting configuration corresponding to the first target information is a target reporting configuration, and the target reporting configuration adopts at least one of the following:
[0131] The first reporting configuration, which adopts at least one of the CSI reporting configuration and the LTM-CSI reporting configuration;
[0132] The second reporting configuration, which is a reporting configuration different from the CSI reporting configuration and the LTM-CSI reporting configuration.
[0133] In the embodiments of the present application, when reporting the above first target information, the reporting configuration of the above first target information may follow at least one of the existing CSI reporting configuration and the LTM-CSI reporting configuration, or may additionally configure a reporting configuration different from the CSI reporting configuration and the LTM-CSI reporting configuration.
[0134] Optionally, when the target reporting configuration adopts the first reporting configuration, the terminal performs a first operation when the first condition is met, including: the terminal performs the first operation when the first reporting configuration includes a first configuration parameter and the first condition is met; or, the terminal performs the first operation when the first configuration parameter is included in the first configuration information and the first condition is met; the first configuration information is configuration information other than the first reporting configuration.
[0135] When the reporting configuration (target reporting configuration) of the above first target information follows at least one of the existing CSI reporting configuration and LTM-CSI reporting configuration, optionally, a configuration parameter is specifically set in the target reporting configuration or in the remaining configuration information other than the target reporting configuration, and this configuration parameter can be used to indicate whether the terminal performs the first operation based on the first condition. Optionally, the remaining configuration information other than the target reporting configuration includes at least one of CellGroupConfig, ServingCellConfig, CSI-MeasConfig, Bandwidth Part (BWP), and BWP-DownlinkDedicated.
[0136] For example, when the above configuration parameter is configured in the target reporting configuration (i.e., the above configuration parameter is configured as the first configuration parameter), the terminal performs the first operation when the first condition is met; if not configured, the terminal reports according to the reporting characteristics configured in the target reporting configuration, such as periodic, semi-persistent, or aperiodic reporting; in another embodiment, the above configuration parameter is an enabling parameter. When the above configuration parameter is included in the target reporting configuration and the above configuration parameter is enabled (i.e., the above configuration parameter is configured as the first configuration parameter), the terminal performs the first operation when the first condition is met. When the above configuration parameter is disabled or the above configuration parameter is not configured in the target reporting configuration, the terminal does not perform the first operation based on the first condition. Further optionally, the terminal reports according to the reporting characteristics configured in the target reporting configuration, such as periodic, semi-persistent, or aperiodic reporting.
[0137] For example, when the above configuration parameter is configured in the remaining configuration information except the target report configuration (i.e., the above configuration parameter is configured as the first configuration parameter), the terminal performs a first operation when the first condition is met; if not configured, the terminal reports according to the reporting characteristics configured in the third report configuration, such as periodic, semi-persistent, or aperiodic reporting; in another embodiment, the above configuration parameter is an enabling parameter. When the above configuration parameter is configured and enabled in the remaining configuration information except the target report configuration (i.e., the above configuration parameter is configured as the first configuration parameter), the terminal performs a first operation when the first condition is met. When the above configuration parameter is disabled or the above configuration parameter is not configured in the remaining configuration information except the target report configuration, the terminal does not perform the first operation based on the first condition. Further optionally, the terminal reports according to the reporting characteristics configured in the third report configuration, such as periodic, semi-persistent, or aperiodic reporting. The third report configuration includes at least one report configuration included in the remaining configuration information except the target report configuration. For example, when the first configuration parameter is configured in ServingCellConfig and the first condition is met, the terminal performs the first operation; if the first configuration parameter is not configured in ServingCellConfig, the terminal reports according to the reporting characteristics corresponding to the report configuration included in ServingCellConfig. For example, if CSI report #1 configured in ServingCellConfig is periodic reporting and CSI report #2 is semi-persistent reporting, the terminal performs periodic reporting of CSI report #1 and semi-persistent reporting of CSI report #2.
[0138] It can be understood that the embodiments of the present application are not limited to the terminal performing the first operation when the first condition is met, and the first condition may not be set, and the above first operation is implemented based on the terminal.
[0139] In addition, a second configuration parameter may be set in the first report configuration. The second configuration parameter may instruct the terminal to skip sending the target report on the reporting resource in the first report configuration. The target report is the report corresponding to the first report configuration, and the target report may be a report (first target information) that meets the first condition or a report that does not meet the first condition. The second configuration parameter may be the same as the first configuration parameter.
[0140] In addition, a third configuration parameter may be set in the configuration information other than the first reporting configuration. The third configuration parameter may instruct the terminal to skip sending a target report on the reporting resource in the fourth reporting configuration. The target report is the report corresponding to the fourth reporting configuration. The target report may be a report (first target information) that meets the first condition or a report that does not meet the first condition. The fourth reporting configuration is at least one reporting configuration included in the configuration information other than the first reporting configuration. The third configuration parameter may be the same as the first configuration parameter.
[0141] Optionally, when the target reporting configuration adopts the second reporting configuration, the terminal performs a first operation when meeting the first condition, including: the terminal performs the first operation when obtaining the second reporting configuration and meeting the first condition; the second reporting configuration includes at least one of the following: the first condition, measurement resource configuration information, a reporting configuration index, and reporting configuration information.
[0142] The second reporting configuration of the above first target information is an additional configuration and is different from the CSI reporting configuration and the LTM-CSI reporting configuration. Specifically, the second configuration report may include at least one of the first condition, measurement resource configuration information, a reporting configuration index, and reporting configuration information.
[0143] In addition, the embodiment of the present application is neither the mechanism for triggering reporting by the network-side device in the existing related technology nor the mechanism based on event triggering in the existing related technology (see Table 4), but is triggered by the terminal. Specifically, the first condition and the first operation based on which step 301 is executed enable the above triggering process not to be limited to execution at the L3 layer and can also be executed at the L1 layer, thereby reducing the resource overhead of beam management.
[0144] Optionally, the first target reference signal includes a reference signal whose measurement result meets a preset threshold.
[0145] In the embodiment of the present application, the existence of the first target reference signal can be understood as the existence of a reference signal that meets the preset threshold. The preset threshold may be network-configured or agreed upon by the protocol.
[0146] Optionally, the first target reference signal includes at least one of the following:
[0147] The first reference signal RS, where the measurement result of the first RS plus a first bias value is less than or equal to a first threshold, or the measurement result of the first RS within a first time period plus a second bias value is less than or equal to a second threshold, or the number of times that the measurement result of the first RS within a second time period plus a third bias value is less than or equal to a third threshold is greater than or equal to N1, where the first RS is the reference signal corresponding to the beam currently used by the terminal, and N1 is a positive integer;
[0148] The second RS, where the measurement result of the second RS minus a fourth bias value is greater than or equal to the measurement result of the first RS;
[0149] The third RS, where the measurement result of the third RS within a third time period minus a fifth bias value is greater than or equal to the measurement result of the first RS;
[0150] The fourth RS, where the number of times that the measurement result of the fourth RS within a fourth time period minus a sixth bias value is greater than or equal to the measurement result of the first RS is greater than or equal to N2, and N2 is a positive integer;
[0151] The fifth RS, where the measurement result of the fifth RS minus a seventh bias value is greater than or equal to the measurement result of the eighth RS;
[0152] The sixth RS, where the measurement result of the sixth RS within a fifth time period minus an eighth bias value is greater than or equal to the measurement result of the eighth RS;
[0153] The seventh RS, where the number of times that the measurement result of the seventh RS within a sixth time period minus a ninth bias value is greater than or equal to the measurement result of the eighth RS is greater than or equal to N3, and N3 is a positive integer.
[0154] In the embodiments of the present application, the above first condition can be understood as at least one of the following:
[0155] 1) The measurement result of the RS (the first RS) corresponding to the beam currently used by the current terminal plus a first bias value is still lower than the first threshold;
[0156] 2) The measurement result of the RS (the first RS) corresponding to the beam currently used by the current terminal plus a second bias value is always lower than the second threshold within a first time period;
[0157] 3) The number of times that the measurement result of the RS (the first RS) corresponding to the beam currently used by the current terminal plus a third bias value is lower than the third threshold within a second time period is not less than N1;
[0158] The RS corresponding to the beam currently used by the terminal in the above conditions 1)-3) includes at least one of the following:
[0159] The Quasi Co-Location (QCL) source reference signal (source RS) of the TCI state of at least one control resource set (CORESET) includes at least the QCL-Type D source RS;
[0160] The QCL source RS of at least one activated TCI state(s) for PDSCH includes at least the QCL-Type D source RS;
[0161] The QCL source RS of the TCI state indicated by the network side device includes at least the QCL-Type D source RS;
[0162] The above TCI state is applicable to at least one of the R15 TCI state configuration framework and the R17 unified TCI state configuration framework.
[0163] Regarding the condition in the above item 3) that uses the number of times of meeting the threshold within a preset time (the second time) as a condition, it can be that the terminal performs a preset number of measurements within the preset time. For example, it performs periodic measurements within the preset time (i.e., periodically configures RS resources), and then the number of times can be counted. The number conditions in conditions 6) and 9) in the following text are similar to this.
[0164] 4) At least one measurement result of the second RS minus the fourth offset value is still higher than the measurement result of the RS (the first RS) corresponding to the beam currently used by the terminal;
[0165] 5) At least one measurement result of the third RS minus the fifth offset value is always greater than the measurement result of the RS (the first RS) corresponding to the beam currently used by the terminal within the third time;
[0166] 6) The number of times that at least one measurement result of the fourth RS minus the sixth offset value is greater than the measurement result of the RS (the first RS) corresponding to the beam currently used by the terminal within the fourth time is not less than N2;
[0167] In the above conditions 4)-6), the measurement results of the measured RS are compared with the measurement results of the RS corresponding to the beam currently used by the terminal to determine whether there is a first target reference signal. Optionally, the above second RS, third RS, and fourth RS can be the RS of the neighboring cell or the RS configured by the network side device.
[0168] 7) At least one measurement result of the fifth RS minus the seventh offset value is still greater than the measurement result of the eighth RS;
[0169] 8) The measurement result of at least one sixth RS minus the eighth offset value is always greater than the measurement result of the eighth RS within the fifth time period;
[0170] 9) The number of times that the measurement result of at least one seventh RS minus the ninth offset value is greater than the measurement result of the eighth RS within the sixth time period is not less than N3;
[0171] In the above conditions 7)-9), the measurement results of the measured RSs are compared with the measurement result of a specific RS (the eighth RS) to determine whether there is a first target reference signal. The above eighth RS can be an RS configured by the network device or an RS of the current serving cell. Alternatively, the fifth RS, the sixth RS, and the seventh RS are the RSs with the best measurement results at the first reporting moment, and the eighth RS is the RS with the best measurement result at the second reporting moment, and the second reporting moment is earlier than the first reporting moment. That is, it can be understood that when an RS better than the RS at the previous reporting moment is found at a subsequent reporting moment, it is considered that there is a first target RS, and the first operation is triggered to be executed.
[0172] Optionally, each of the above fifth RS, sixth RS, and seventh RS can be associated with a different reporting configuration from the above eighth RS.
[0173] In the embodiments of the present application, the above offset value, threshold, time (start time or duration), and the values of N1, N2, and N3 are all configured or indicated by the network, or are default specified by the protocol.
[0174] In the embodiments of the present application, the above first RS to eighth RS, and the above second target reference signal are configured by the network or agreed upon by the protocol, and they can all be associated with different objects or the same object.
[0175] Optionally, at least one of the timing advance TA, configuration information, and frequency point related information of the target object satisfies a preset condition.
[0176] In the embodiments of the present application, at least one of the TA, configuration information, and frequency point related information of the object is used as a screening condition parameter for the target object. When at least one of the above parameters of the above object satisfies a preset condition, the object is the target object, that is, there is a target object that triggers the first operation.
[0177] Optionally, the target object satisfies at least one of the following:
[0178] The TA value of the target object is 0;

[0182] The frequency point information of the synchronization signal block (SSB) of the target object is the same as the frequency point information of the measurement object currently configured by the terminal;
[0183] The target object is a known object.
[0184] In the embodiments of the present application, the first condition includes: there is at least one target object, and the target object satisfies at least one of the following:
[0185] 1) The timing advance (TA) value of the target object is 0 or the TA of the target object is the same as that of the current serving object of the terminal;
[0186] 2) The TA of the target object can be obtained through the TA measurement and calculation of the terminal (UE-based TA measurement);
[0187] Wherein, the TA value of the target object is obtained based on the measurement and calculation of the terminal, and needs to satisfy at least one of the following conditions:
[0188] The value of the first parameter in the configuration information for triggering handover of layer 1 or layer 2 corresponding to the target object is the same as the value of the first parameter in the configuration information corresponding to the current serving object; the first parameter is used to indicate whether the terminal can perform TA measurement and calculation;
[0189] The number of target objects does not exceed the first UE capability, and the first UE capability is the maximum number of target objects supported by the terminal that can obtain TA through UE TA measurement and calculation.
[0190] 3) The target configuration information corresponding to the target object includes the configuration information of the random access channel (RACH), and the target configuration information is used for LTM;
[0191] 4) The frequency point information of the SSB of the target object is the same as the frequency point information in a measurement object (Meas Object) currently configured by the terminal;
[0192] 5) The target object is a known object (known);
[0193] Among them, taking a known cell as an example, a known cell for a neighboring cell or a candidate cell satisfies at least one of the following conditions:
[0194] The UE has performed L3 measurements on this cell for a period of time;
[0195] The SSB for L1 measurement of the cell is detectable.
[0196] Optionally, the terminal sends first target information to the network-side device, including at least one of the following:
[0197] Send the first target information on a first resource; the first resource is configured, indicated, or scheduled by the network-side device;
[0198] Send the first information on a second resource and send the second information on a third resource, where the first target information includes at least one of the first information and the second information; the second resource is configured, indicated, or scheduled by the network-side device; the third resource is determined by at least one of configuration, indication, scheduling, and terminal indication by the network-side device.
[0199] In the embodiments of the present application, when the terminal sends first target information to the network side, it includes that the terminal sends the target information on a target uplink resource, including but not limited to at least one of the following:
[0200] a) The terminal sends the target information on a first uplink resource configured, indicated, or scheduled by the network side;
[0201] b) The terminal sends the first information on a second uplink resource configured, indicated, or scheduled by the network side and sends the second information on the third uplink resource, where the third uplink resource is determined by at least one of configuration, indication, scheduling, and terminal indication by the network-side device.
[0202] The terminal can report the first target information based on at least one of the resources configured, indicated, or scheduled by the network-side device or indicated by the terminal. The above reporting can be performed on a first uplink resource configured, indicated, or scheduled by the network side, or the first target information can be divided into two types of information (the first information and the second information) and reported separately.
[0203] Optionally, the first information includes at least one of the following:
[0204] Indication information on whether the second information exists;
[0205] Size information of the second information;
[0206] Indication information of the third resource;
[0207] The identifier of the reference signal of at least one of the first target reference signal with the best measurement result and the second target reference signal with the best measurement result;
[0208] The measurement result of the reference signal of at least one of the first target reference signal with the best measurement result and the second target reference signal with the best measurement result;
[0209] The quantity of at least one of the first target reference signal and the second target reference signal carried in the second information.
[0210] In the embodiments of the present application, the first information for reporting the first target information on the second resource may be, optionally, the above first information may be understood as the content indication and resource indication of the first target information, and the second information may be understood as the content of the first target information itself (at least one of the relevant information of the first target reference signal, the relevant information of the second target reference signal, the transmission configuration indication (TCI) relevant information, and the beam assistance information).
[0211] The first target information reported on the first resource may be understood to include the content indication of the first target information, as well as the content of the first target information itself, and the content of the first target information itself may also be understood to only include the content of the first target information itself.
[0212] The first information includes but is not limited to at least one of the following:
[0213] a) Whether the second information exists; for example, indicated by 1 bit, that is, 0 means none, and 1 means yes;
[0214] b) The size of the second information;
[0215] c) The resource indication of the third uplink resource;
[0216] d) The identifier of the reference signal of at least one of the first target reference signal with the best measurement result and the second target reference signal with the best measurement result;
[0217] e) The measurement result of the reference signal of at least one of the first target reference signal with the best measurement result and the second target reference signal with the best measurement result;
[0218] f) The quantity of at least one of the first target reference signal and the second target reference signal carried in the second information.
[0219] The second information contains part or all of the content of the first target information other than the first information in the first target information;
[0220] A possible situation is that the first target information only reports the first information and does not include the second information, that is, the first information indicates that the second information does not exist, the first information indicates that the size of the second information is 0, and at least one of the third resources is not in use. In this case, when the second information does not exist, it is possible to indicate the non-existence of the second information only through the second resource, so that the network-side device can use the third resource for other-purpose transmissions. That is, in the embodiments of the present application, by dynamically indicating the resource carrying the second information, the purpose of rationalizing resource utilization can be achieved.
[0221] It should be noted that when the first information indicates that the second information does not exist, optionally, the first information does not include the resource indication of the third uplink resource and the size of the first information. The size of the second information can be indicated by specifying the number of bits, or by indicating the order of the specific number of bits after quantization. For example, 3 bits are used to indicate 0 to 79 bits, where 0 represents 0 to 9, 1 represents 10 to 19, and so on, and 7 represents 70 to 79; when the actual number of bits of the second information is 50, the size of the second information can be indicated by directly indicating 50 or 5.
[0222] Optionally, the carrying manner of the first target information adopts at least one of the following:
[0223] The first target information is at least part of the information of CSI part 2;
[0224] The first information is at least part of the information of CSI part 0, and the second information is at least part of the information of CSI part 1 or part 2;
[0225] The first information is at least part of the information of CSI part 1, and the second information is at least part of the information of CSI part 2.
[0226] In the embodiments of the present application, the terminal determines the UCI sequence corresponding to the first target information according to at least one of the following methods:
[0227] 1) The first target information is part of the information of CSI part 2;
[0228] 2) The first target information is divided into two parts to determine the UCI sequence, where the first part is composed of the first information and the second part is composed of the second information;
[0229] Optionally, the UCI sequence is a new UCI sequence; further optionally, the first part is CSI part 0, and the second part is CSI part 1 or CSI part 2; where CSI part 0 is the newly added UCI information;
[0230] Optionally, the first part may be CSI part 1, and the second part may be CSI part 2;
[0231] Optionally, when the terminal performs resource mapping, it maps the UCI sequence to the resources for transmission in the order of the first part first and the second part second. That is, it preferentially reads the content of the first information to determine whether the second information exists or the resource location of the second information, thereby improving the efficiency of information acquisition.
[0232] Optionally, the method further includes:
[0233] When the transmission resources of the first target information and the third information overlap in the time domain at the terminal, the terminal determines the priority order of the first target information and the third information according to a first preset rule.
[0234] In the embodiments of the present application, when there is a conflict in the transmission resources between the first target information reported by the terminal and other information (the third information), the transmission priority between the conflicting information can be determined based on a preset rule (the first preset rule).
[0235] It can be understood that the above overlap in the time domain can be understood as partial or complete overlap of time domain resources.
[0236] When there is an overlap in the frequency domain and the spatial domain, other preset rules can be used to determine the priority between the conflicting information.
[0237] Optionally, the third information includes any one of the following:
[0238] CSI report, LTM-CSI report, second target information;
[0239] Wherein, the second target information is a target information with at least some features different from those of the first target information.
[0240] In the embodiments of the present application, the information conflicting with the first target information may be at least one of a CSI report, an LTM-CSI report, and a second target information.
[0241] The above CSI report includes at least one of a beam report (the report content is at least one of L1-RSRP and L1-SINR) and a CSI report (the report content is at least one of a precoding indication PMI, a channel quality indication CQI, a rank indication, and a layer indication).
[0242] The above LTM-CSI report may also be described as an LTM report.
[0243] The above CSI report and LTM-CSI report can be understood as reports triggered by network-side devices.
[0244] In the embodiments of the present application, the first target information is the target information sent by the terminal when the first condition is met. The second target information can be understood as other target information sent by the terminal when the first condition is met and different from the first target information. Among them, the second target information is the target information with at least some features different from those of the first target information. The sending conditions, content, and transmission methods of the second target information are similar to those of the first target information. However, at least some of the feature information included in the second target information (for example, at least one of the content included in the second target information, the corresponding report configuration, the corresponding first condition, and the corresponding measurement configuration information) is different from the first target information.
[0245] Optionally, the first preset rule includes at least one of the following:
[0246] Determine the priorities of the first target information and the third information based on the priorities configured by the network;
[0247] Determine the priorities of the first target information and the third information according to a preset priority calculation formula;
[0248] The priority of the report carrying the first target information is higher than the priority of the LTM-CSI report;
[0249] The priority of the report carrying the first target information is higher than the priority of the CSI report;
[0250] The priority of the first information corresponding to the second target information is higher than the priority of the second information corresponding to the first target information;
[0251] The priority of the first information corresponding to the first target information is higher than the priority of the second information corresponding to the second target information;
[0252] The priority of the first information corresponding to the first target information is higher than the priority of the second information corresponding to the first target information;
[0253] The priority of the first information corresponding to the second target information is higher than the priority of the second information corresponding to the second target information;
[0254] The priority of the report carrying the third target information is higher than the priority of the report carrying the fourth target information; where the third target information is one of the first target information and the second target information, and the fourth target information is the other of the first target information and the second target information;
[0255] The third target information satisfies at least one of the following conditions:
[0256] There is at least one measurement resource associated with the target object in the measurement resources associated with the report carrying the third target information;
[0257] The third target information is associated with at least one target object;
[0258] The report corresponding to the third target information is configured as an LTM-CSI report configuration;
[0259] The priority of the first condition corresponding to the third target information is higher than the priority of the first condition corresponding to the fourth target information;
[0260] The fourth target information satisfies at least one of the following conditions:
[0261] The measurement resources associated with the report carrying the fourth target information are only associated with the current serving object of the terminal;
[0262] The fourth target information is associated with the current serving object of the terminal;
[0263] The report corresponding to the fourth target information is configured as a CSI report configuration;
[0264] The priority of the first condition corresponding to the fourth target information is lower than the priority of the first condition corresponding to the third target information.
[0265] In the embodiments of the present application, the above priority rule (the first preset rule) may be pre-configured by the network-side device. For example, the network may explicitly configure the first priority value of different reports; further optionally, the higher the first priority value, the higher the priority, or the lower the first priority value, the higher the priority;
[0266] The above priority rule (the first preset rule) may also be calculated based on a preset priority formula. For example, the CSI report priority formula in the foregoing may be adopted.
[0267] The above first preset rule may also be pre-specified that the priority of the report carrying the target information is higher than the priority of the LTM report; or the priority of the report carrying the target information is higher than the priority of the CSI report. It can be understood that the priority of the report triggered by the terminal is higher than the priority of the report triggered by the network side.
[0268] The above first preset rule may also be pre-specified that the priority corresponding to the first information is higher than the priority of the second information. The first information and the second information may be information in different target information or information in the same target information. Specifically, the priority corresponding to the first information of the second target information is higher than the priority of the second information of the first target information; the priority corresponding to the first information of the first target information is higher than the priority of the second information of the second target information; the priority corresponding to the first information of the first target information is higher than the priority of the second information of the first target information; the priority corresponding to the first information of the second target information is higher than the priority of the second information of the second target information; that is, in the case of conflict between the first target information and the second target information, the first information carried by both can be preferentially transmitted.
[0269] In the embodiments of the present application, in the case of conflict between the first target information and the second target information, the priorities of the relevant information of the first target information and the second target information can be first judged, so as to determine the third target information with a higher priority and the fourth target information with a lower priority from the first target information and the second target information. The priority of the report carrying the third target information is higher than the priority of the report carrying the fourth target information.
[0270] Specific screening rules may be that the report carrying the third target information satisfies at least one of the following conditions:
[0271] There is at least one measurement resource associated with the target object among the measurement resources associated with the report;
[0272] There is at least one piece of information in the third target information that is associated with at least one target object. For example, the second target reference signal is a reference signal associated with the target object, or the TCI state is associated with the target object, or the QCL source RS of the TCI state is associated with the target object;
[0273] The report associated with the report configuration is LTM-CSI-ReportConfig (when the corresponding target information adopts the first report configuration and the LTM-CSI report configuration is adopted);
[0274] The priority of the first condition corresponding to the third target information is high; optionally, the priority of the first condition is configured or indicated by the network or specified by the protocol;
[0275] Specific screening rules may be that the report carrying the fourth target information satisfies at least one of the following conditions:
[0276] All the measurement resources associated with the report are only associated with the current serving object;
[0277] The fourth target information is all associated with the current service object. For example, the second target reference signal, TCI state, etc.;
[0278] The report association report is configured as CSI-ReportConfig (in the case of using the first report configuration for the corresponding target information and using the CSI report configuration);
[0279] The priority of the first condition corresponding to the fourth target information is low. Further optionally, the priority of the first condition is configured or indicated by the network, or stipulated by the protocol.
[0280] Optionally, the method further includes at least one of the following:
[0281] After a first preset time after the terminal receives the first physical downlink control channel PDCCH sent by the network side device, the terminal performs data transmission according to the target beam information corresponding to the first target information. Wherein, the hybrid automatic repeat request HARQ process identifier scheduled by the first PDCCH is the same as that of the target physical uplink shared channel PUSCH, the new data indicator NDI in the first PDCCH is inverted relative to the NDI in the PDCCH scheduling the target PUSCH, the target PUSCH is the PUSCH carrying the first target information, and the first preset time is greater than or equal to 0;
[0282] After a second preset time after the terminal receives the second PDCCH sent by the network side device, the terminal performs data transmission according to the target beam information corresponding to the first target information. The second PDCCH carries beam switching indication information, and the second preset time is greater than or equal to 0.
[0283] In the embodiment of the present application, after the terminal sends the first target information, a second operation is performed. The second operation includes but is not limited to at least one of the following:
[0284] After the terminal sends the target information on the PUSCH, after a first preset time after receiving a PDCCH with a scheduling HARQ process ID the same as that of the PUSCH but with an inverted NDI, the terminal will receive downlink signals and data and / or send uplink signals and data using the beam information indicated in the first target information; the above first preset time is greater than or equal to 0. When the first preset time is equal to 0, it can be considered that when the first PDCCH is received, the target beam becomes effective and is used. When the first preset time is greater than 0, it can be considered that after a preset duration after receiving the first PDCCH, the target beam becomes effective and is used.
[0285] After the terminal sends the target information on the PUCCH, when it receives a PDCCH carrying beam switching indication information (optionally, the beam switching indication information is indicated by 1 bit, 0 indicates no beam change, and 1 indicates beam switching), and after a second preset duration when the switching indication information indicates beam switching (i.e., when the second PDCCH is received), the terminal will receive downlink signals and data, and / or send uplink signals and data using the beam information indicated in the first target information; the above second preset time is greater than or equal to 0. When the second preset time is equal to 0, it can be considered that when the second PDCCH is received, the target beam becomes effective and is used. When the second preset time is greater than 0, it can be considered that after the preset duration after the second PDCCH is received, the target beam becomes effective and is used.
[0286] The beam switching indication information can be carried by a new DCI format, or in an existing DCI format by adding a new field or indicating with reserved bits.
[0287] It can be understood that the terminal can receive the above first PDCCH and second PDCCH using the current beam, or can also receive the above first PDCCH and second PDCCH using the target beam information corresponding to the first target information.
[0288] In the embodiments of this application, the beam and the target beam are usually indicated or determined by at least one of TCI state, TCI-UL-state, spatial relation, QCL assumption, QCL-type D source reference signal, and RS.
[0289] In the embodiments of this application, when the terminal sends the first target information (carrying beam-related information) to the network-side device and the network-side device feeds back the PDCCH, the negotiation of the target beam can be achieved. This process is significantly different from the beam activation and indication process in the related art (see Figure 2 ), that is, the timeline of beam management or beam switching is improved, and the beam switching delay can be effectively reduced.
[0290] Optionally, when the first target information includes the relevant information of multiple first target reference signals, or the relevant information of multiple second target reference signals, or the relevant information of multiple TCI, the performing data transmission according to the target beam information corresponding to the first target information includes:
[0291] Determining the target beam information corresponding to the first target information according to a second preset rule;
[0292] Performing data transmission using the target beam information;
[0293] Among them, the second preset rule includes any one of the following:
[0294] Determine the target beam information according to the measurement result of the first target reference signal;
[0295] Determine the target beam information according to the measurement result of the second target reference signal;
[0296] Determine the target beam information according to the arrangement order of the multiple TCI-related information.
[0297] In the embodiment of the present application, when the number of the related information of the first target reference signal, or the related information of the second target reference signal, or the TCI-related information carried in the first target information is 1, the terminal directly determines the beam information according to the first target information for receiving downlink signals and data, and / or sending uplink signals and data;
[0298] When the number of the related information of the first target reference signal, or the related information of the second target reference signal, or the TCI-related information carried in the first target information is greater than 1, the terminal determines the target beam information according to the second preset rule for receiving downlink signals and data, and / or sending uplink signals and data.
[0299] Exemplarily, the second preset rule includes but is not limited to at least one of the following:
[0300] Determine the target beam information according to the first target reference signal arranged first;
[0301] Determine the target beam information according to the second target reference signal arranged first;
[0302] Determine the target beam information according to the first target reference signal with the largest measurement value result;
[0303] Determine the target beam information according to the second target reference signal with the largest measurement value result;
[0304] Determine the target beam information according to the TCI state and / or TCI-UL-State corresponding to the TCI codepoint with the smallest TCI codepoint index in the first target information;
[0305] Determine the target beam information according to the TCI state and / or TCI-UL-State with the smallest TCI state id in the first target information, etc.
[0306] It can be understood that the above second preset rule is only an example, and the above second preset rule can be determined by including at least one of the relevant information of the first target reference signal, the relevant information of the second target reference signal, the transmission configuration indication (TCI) relevant information, and the beam assistance information in the first target information.

[0319] The corresponding priorities are: LTM CSI report triggered by the terminal > CSI report triggered by the terminal > LTM CSI report > CSI report
[0320] If there are multiple reporting resources corresponding to the LTM-CSI reports triggered by the terminal that overlap in the time domain, when the second condition is met, the terminal can calculate the priority value according to a preset priority calculation formula (for example, the CSI priority formula), and multiplex and transmit the multiple LTM-CSI reports triggered by the terminal in ascending order of the priority value, or discard the LTM CSI report triggered by the terminal with a high priority value; Optionally, the second condition is agreed upon by the protocol;
