[0004] The beam management mechanism in related technologies typically detects beam quality through beam measurement and reporting triggered by network-side equipment. The network-side equipment then configures, activates, and indicates beams 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 changes rapidly with movement. To ensure real-time beam tracking, the network-triggered beam management mechanism requires frequent beam reporting triggered by the network. Periodic beam reporting will lead to increased uplink resource overhead, while non-periodic beam reporting will result in high signaling overhead.

[0059] For ease of understanding, some of the contents involved in the embodiments of this application are described below:

[0060] About beam measurement:

[0061] Analog beamforming uses full-bandwidth transmission, and each polarization element on each high-frequency antenna array panel can only transmit analog beams in a time-division multiplexed manner. The shaping weights of the analog beams are achieved by adjusting the parameters of devices such as the RF front-end phase shifter.

[0062] Currently, in academia and industry, polling is commonly used to train simulated beamforming vectors. That is, the array elements in each polarization direction of each antenna panel send training signals (i.e., candidate beamforming vectors) in sequence at agreed times in a time-division multiplexing manner. After measurement, the terminal feeds back a beam report, which the network side uses to implement simulated beam transmission in the next service transmission using the training signal.

[0063] Current technologies only support beam measurement using the Channel State Information-Reference Signal (CSI-RS) or the Synchronization Signal / Physical Broadcast Channel (PBCH) block (SSB). The CSI-RS used for beam measurement only has one or two ports. The SSB is a periodic reference signal, while the CSI-RS used for beam measurement can be periodic, semi-persistent, or aperiodic.

[0064] Beam measurement is divided into Layer 1 (L1) beam measurement and Layer 3 (L3) beam measurement. In Releases 15 and 16, L1 beam measurement is limited to the serving cell. Release 15 only supports L1 Reference Signal Received Power (RSRP) measurement. Release 16 introduces L1 Signal to Interference plus Noise Ratio (SINR), taking inter-cell interference or inter-user interference into account in beam measurement. Release 17, under the Cross-Cell Beam Management and Cross-Cell Multiple Transmitter and Receiver Node projects, supports L1 beam measurement of neighboring cells that are co-frequency and synchronized with the current serving cell. Release 18, under the Mobility Enhancement project, supports L1 beam measurement of asynchronous, heterodyne neighboring cells. Both currently support only SSB-based L1-RSRP measurement. Based on the reporting mechanism triggered by the network-side device, the terminal performs L1 beam measurement according to the measurement resources configured by the network-side device, and selects a beam for reporting based on the measurement results.

[0065] About beam reporting:

[0066] The reported measurement quantities for L1 beam reporting triggered by network-side devices currently supported in the protocol are L1-RSRP / L1 Reference Signal Received Quality (RSRQ) / L1-SINR. Beam reporting methods include group-based and non-group-based. For non-group-based beam reporting, based on the reported measurement quantity, the terminal selects up to four beams from all measurement resources associated with the L1 beam report configured on the network side for reporting. For group-based beam reporting, in Release 15 / 16, the terminal selects a pair of beams that can be simultaneously received by the UE for reporting based on the reported measurement quantity.

[0067] In the relevant protocols, if the report quantity field in the higher-layer parameter 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. Furthermore, when the group-based beam reporting (groupBasedBeamReporting) field is enabled, the UE can only report one pair of beams: two channel measurement resource (CMR) identifiers and their corresponding L1-RSRP / L1-SINR values, where the CMR identifiers include the channel state information-reference signal resource indicator (CSI-RS Resource Indicator, CRI) or the SSB resource indicator (SSBRI). When the groupBasedBeamReporting field is disabled, the UE may report the CMR identifiers and their corresponding L1-RSRP corresponding to four beams. When the number of reported beams is greater than 1, all L1-RSRP / L1-SINR values ​​except the maximum L1-RSRP / L1-SINR are reported by taking the difference from the maximum value. The specific uplink control information (UCI) mapping rules for CSI reporting (L1-RSRP) are shown in Tables 1 and 2, and the L1-SINR is similar. It should be noted that the CRI / SSBRI position corresponds to the RSRP position. CRI / SSBRI#1 corresponds to RSRP#1, and RSRP#1 is the maximum of the four RSRPs.

[0068] Table 1 UCI mapping order reported by Release 15 / 16 L1 beam

[0069] Table 2 UCI bit overhead

[0070] The above-mentioned reference signal RS identifier and the number of UCI bits of L1-RSRP are shown in Table 2, and L1-SINR is similar. is the number of CSI-RS resources configured in a CSI-RS resource set. The number of SSB resources configured in an SSB resource set. The current protocol supports a maximum of 64 RS resources in an RS (CSI-RS / SSB) set.

[0071] In Release 17, the multiple transmission and reception node project enhances group-based beam reporting. From the network-configured measurement resources, the terminal can select up to four pairs of beams that the UE can simultaneously receive for reporting. Within each pair of beams, different beams correspond to different transmission and reception nodes, ensuring that the network can simultaneously transmit these beams. The UCI mapping table is shown in Table 3.

[0072] Table 3 UCI mapping order reported by Release 17 L1 beam

[0073] Release 18's Layer 1 / L2-Triggered Mobility (LTM) project introduced the L1 reporting feature for handover, namely ltm-CSI-ReportConfig. In one L1 report for handover, a terminal can report up to four cells, with each cell reporting four beam measurement results, for a maximum of 16 beams and their corresponding measurement results.

[0074] Regarding the priority of CSI reports:

[0075] In the 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 according to the CSI report priority formula. The lower the priority evaluation value of the CSI report, the higher the priority of the CSI report. Subsequently, the terminal will sort and UCI map according to the priority of the CSI report. When the reporting resource cannot carry the multiple CSI reports, the CSI report with low priority will be discarded. The CSI report priority formula is as follows: CSI (y,k,c,s)=2·N cells ·M s y+Ncells ·M s k+M s c+s

[0076] Wherein, for aperiodic CSI reporting reported on the Physical Uplink Shared Channel (PUSCH), y=0; for semi-persistent CSI reporting reported on the PUSCH, y=1; for semi-persistent CSI reporting reported on the Physical Uplink Control Channel (PUCCH), y=2; for CSI reporting reported on the PUCCH, y=3;

[0077] For CSI reports where the measurement quantity reported is L1-RSRP or L1-SINR, k=0; otherwise, k=1;

[0078] c is the serving cell index associated with the CSI report;

[0079] N cells is the value of the Radio Resource Control (RRC) parameter maximum number of configurable serving cells (maxNrofServingCells);

[0080] s is the CSI report configuration identifier (CSI-ReportConfigId);

[0081] M s The value of the maximum number of CSI report configurations that can be configured by the RRC parameter (maxNrofCSI-ReportConfigurations);

[0082] Release 18 introduces LTM reports (also known as LTM-CSI reports, LTM CSI reports, LTM reports, or LTM-CSI reports). These reports serve as CSI information to determine UCI sequences and resource mapping. LTM reports always take precedence over CSI reports in the event of a resource conflict.

[0083] Regarding beam activation and indication:

[0084] As shown in Figure 2, the TCI state of the Physical Downlink Shared Channel (PDSCH) must first be activated by selecting at least one TCI state from the TCI state list through the Media Access Control Element (MAC CE). According to the annotations, RAN1 stipulates that the TCI state carried in the MAC CE can only be activated 3ms after the PUCCH carrying the ACK corresponding to the MAC CE used to activate the TCI state. However, according to the RAN4 protocol, the activation delay of the TCI state is not only the ACK+3ms specified by RAN1, but also the time to wait for one SSB for synchronization. Therefore, the activation delay of the TCI state is ACK+3ms+first SSB.

[0085] If the MAC CE activates more than one TCI state, the DCI is required to indicate one of the activated TCI states for the terminal to receive data. For DCI-based beam indication, RAN1 specifies a beam application delay of one slot. This means that in the first slot after the PUCCH carrying the ACK for the DCI-scheduled PDSCH, the terminal uses the indicated TCI state for data reception. Therefore, the TCI state application delay is ACK + Y slots.

[0086] Regarding event-triggered measurement and reporting:

[0087] In relevant protocols, event-triggered measurements and reported measurement quantities are L3 measurement results. Their main purpose is to evaluate cell quality to facilitate cell handover. The event definitions are shown in Table 4.

[0088] Table 4 Event Definition

[0089] In Table 4, the parameters are explained as follows:

[0090] Ms: Serving cell measurement result, without considering any offset;

[0091] Mn: Neighboring cell measurement result, without considering any offset;

[0092] Ofn: Neighborhood measurement object specific offset;

[0093] Ocn: Neighboring cell-level specific offset;

[0094] Mp: SpCell (primary serving cell) measurement result, without considering any offset;

[0095] Ofp: SpCell measurement object specific offset;

[0096] Ocp: SpCell cell-level specific offset;

[0097] Hys: hysteresis parameter of the event;

[0098] Off: offset parameter of the event;

[0099] Mi: interference measurement result;

[0100] Thresh: threshold.

[0101] In the relevant beam management mechanism, the terminal detects beam quality through beam measurement and reporting triggered by network-side equipment. The network-side equipment then configures, activates, and indicates beams 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 changes rapidly with movement. Especially in Frequency Range 2 (FR2) scenarios, the beam management mechanism triggered by network-side equipment has the following problems:

[0102] 1) To ensure real-time beam tracking, network-side devices need to trigger frequent beam reporting. Periodic beam reporting increases uplink resource overhead, while aperiodic beam reporting increases signaling overhead. Because it is triggered by network-side devices, the same beam may appear in multiple beam reports reported by the terminal (for example, the terminal repeatedly reports in the same state), resulting in a waste of reporting resources or downlink triggering resources.

[0103] 2) For PDSCH beams, they are often applied through a series of steps such as beam measurement-reporting-activation-indication. Therefore, it is possible that the beam pair used by the terminal is not the current optimal beam pair, thereby affecting data reception performance.

[0104] With the development of large-scale antenna technology and the expansion of high-speed mobile scenarios, the beam width is narrow and changes rapidly with movement. The beam management mechanism based on network triggering has the problem of high resource overhead and further the problem of long beam switching delay.

[0105] Related technologies have supported UE-triggered beam management mechanisms (i.e., event-triggered measurement and reporting). However, event-triggered measurement reporting only supports L3 measurements and is reported at the RRC layer, and cannot flexibly implement the function of UE-triggered beam management based on L1 measurements.

[0106] The beam management method, apparatus, terminal, device and medium provided in the embodiments of the present application are described in detail below with reference to some embodiments and their application scenarios in combination with the accompanying drawings.

[0107] Referring to FIG. 3 , FIG. 3 is a flowchart of a beam management method provided in an embodiment of the present application, which is used for a terminal. As shown in FIG. 3 , the method includes the following steps:

[0108] Step 301: When a first condition is met, the terminal performs a first operation;

[0109] The first condition includes at least one of the following:

[0110] There is at least one first target reference signal;

[0111] There is at least one target object, which is different from the current service object of the terminal;

[0112] The first operation includes at least one of the following:

[0113] performing at least one of beam measurement and channel state information (CSI) measurement on the second target reference signal;

[0114] The first target information is sent 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 related information and beam auxiliary information.

[0115] In an embodiment of the present application, the terminal's satisfaction of the first condition is used as a trigger condition for executing the beam management operation (first operation). That is, the embodiment of the present application is different from the relevant mechanism of the network-side device triggering beam management in the related art. By setting the first condition, the terminal will trigger beam management only when there is a target reference signal (first target reference signal) or a target object. It can be understood as a terminal-triggered beam management method, which can reduce unnecessary beam reporting and effectively reduce the resource overhead of beam management.

[0116] In the embodiment of the present application, the reference signal (RS) can be a CSI-RS, SSB, a tracking reference signal (TRS), a positioning reference signal (PRS), a demodulation reference signal (DMRS), or other reference signals used in the art, and the embodiment of the present application is not limited to this.

[0117] Optionally, the first target reference signal and the target object may be pre-configured by the network or agreed upon by a protocol. The first target reference signal may be of a serving cell or a neighboring cell.

[0118] In this embodiment of the present application, the second target reference signal can be understood as a target reference signal configured by the network side device for the terminal for performing beam measurement or CSI measurement when the first condition is met. The target reference signal can be pre-configured by the network or agreed upon by a protocol. The second target reference signal can be that of the serving cell or a neighboring cell.

[0119] The target object may be an object different from the current terminal service object.

[0120] Optionally, the target object includes at least one of the following:

[0121] Control resource set pool index (CoresetPoolIndex), channel grouping, cell, cell group, distributed unit (Distributed Unit, DU), central unit (Centralized Unit, CU).

[0122] In an embodiment of the present application, the above-mentioned first target information can be understood as the information reported to the network side device by the terminal when the terminal performs beam management when the first condition is met, or in other words, the above-mentioned first target information can be understood as the beam management reporting information of the terminal.

[0123] The above-mentioned first target information may include relevant information of the first target reference signal, that is, when the first target reference signal exists, the terminal reports the relevant information of the above-mentioned first target reference signal to the network side device, for example, it may be at least one of the measurement results and indexes corresponding to the existing first target reference signal.

[0124] The above-mentioned first target information may also include relevant information of the second target reference signal, which may be that when the terminal performs relevant measurement of the second target reference signal (at least one of beam measurement and channel state information CSI measurement) under the condition that the first condition is met, the terminal sends at least part of the measurement results of the second target reference signal (for example, the measurement results that meet the preset threshold, or the best measurement results, or all measurement results) and at least one of the indexes of at least part of the second target reference signal to the network side device.

[0125] The first target information may also include TCI-related information, such as a TCI state identifier (e.g., ID) or a TCI codepoint. Unlike existing related technologies, in which a network device indicates TCI-related information to a terminal, in embodiments of the present application, the terminal may send TCI-related information to the network device. This can be understood as the terminal recommending TCI-related information (e.g., at least one of a TCI state ID and a TCI codepoint) to the network device for signal transmission.

[0126] The above-mentioned first target information may also include beam auxiliary information, for example, a beam change pattern, and the transmitting beam of the network side device predicted by the terminal. The above-mentioned beam change pattern may be the change characteristics of the beam historically used by the terminal or the beam change characteristics obtained by the terminal through beam prediction. The above-mentioned terminal prediction may be performed based on the measurement and observation results of the terminal within a preset time period as a sample.

[0127] In the case where the above-mentioned 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 method, or report the relevant information of N groups of fourth target reference signals in a group-based reporting method. 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 simultaneously by the terminal. Furthermore, the reporting method (group-based or non-group-based) is configured by a network-side device, and the value of N is configured by the network-side device or determined by the UE.

[0128] Optionally, the report configuration corresponding to the first target information is a target report configuration, and the target report configuration adopts at least one of the following:

[0129] a first reporting configuration, where the first reporting configuration adopts at least one of a CSI reporting configuration and an LTM-CSI reporting configuration;

[0130] A second reporting configuration, where the second reporting configuration is a reporting configuration different from the CSI reporting configuration and the LTM-CSI reporting configuration.

[0131] In an embodiment of the present application, when reporting the above-mentioned first target information, the reporting configuration of the above-mentioned first target information may continue to use at least one of the existing CSI reporting configuration and LTM-CSI reporting configuration, or may additionally configure a reporting configuration that is different from the CSI reporting configuration and the LTM-CSI reporting configuration.

[0132] Optionally, when the target report configuration adopts the first report configuration, the terminal performs a first operation when a first condition is met, including: the terminal performs the first operation when the first report configuration includes a first configuration parameter and the first condition is met; or, the terminal includes the first configuration parameter in the first configuration information and performs the first operation when the first condition is met; the first configuration information is configuration information other than the first report configuration.

[0133] When the reporting configuration of the above-mentioned first target information (target reporting configuration) 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. The 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 the cell group configuration CellGroupConfig, the serving cell configuration ServingCellConfig, the CSI measurement configuration CSI-MeasConfig, the bandwidth part (Bandwidth Part BWP), and the BWP downlink dedicated configuration BWP-DownlinkDedicated.

[0134] For example, when the above-mentioned configuration parameters are configured in the above-mentioned target reporting configuration (that is, the above-mentioned configuration parameters are configured as the first configuration parameters), the terminal performs the first operation when the first condition is met; if not configured, reporting is performed according to the reporting characteristics configured in the target reporting configuration, such as periodic, semi-continuous or non-periodic reporting; in another embodiment, the above-mentioned configuration parameters are enabling parameters, and when the target reporting configuration includes the above-mentioned configuration parameters and the above-mentioned configuration parameters are enabled (that is, the above-mentioned configuration parameters are configured as the first configuration parameters), the terminal performs the first operation when the first condition is met; when the above-mentioned configuration parameters are disabled or the above-mentioned configuration parameters are not configured in the target reporting configuration, the terminal does not perform the first operation according to the first condition, and further optionally, reporting is performed according to the reporting characteristics configured in the target reporting configuration, such as periodic, semi-continuous or non-periodic reporting.

[0135] For example, when the above-mentioned configuration parameters are configured in the remaining configuration information other than the target reporting configuration (that is, the above-mentioned configuration parameters are configured as the first configuration parameters), the terminal performs the first operation when the first condition is met; if not configured, reporting is performed according to the reporting characteristics configured in the third reporting configuration, such as periodic, semi-continuous or aperiodic reporting; in another embodiment, the above-mentioned configuration parameters are enabling parameters, and when the above-mentioned configuration parameters are configured in the remaining configuration information other than the target reporting configuration and the above-mentioned configuration parameters are enabled (that is, the above-mentioned configuration parameters are configured as the first configuration parameters), the terminal performs the first operation when the first condition is met. When the above-mentioned configuration parameters are disabled or the above-mentioned configuration parameters are not configured in the remaining configuration information other than the target reporting configuration, the terminal does not perform the first operation according to the first condition, and further optionally, reports according to the reporting characteristics configured in the third reporting configuration, such as periodic, semi-continuous or aperiodic reporting. Wherein, the third reporting configuration includes at least one reporting configuration included in the remaining configuration information other than the target reporting configuration. For example, if 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 reporting configuration included in ServingCellConfig. For example, if CSI report #1 configured in ServingCellConfig is periodic reporting and CSI report #2 is semi-continuous reporting, the terminal performs periodic reporting of CSI report #1 and semi-continuous reporting of CSI report #2.

[0136] 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-mentioned first operation may be performed based on the terminal implementation.

[0137] In addition, a second configuration parameter may be set in the first reporting configuration. The second configuration parameter may instruct the terminal to skip sending a target report on the reporting resource in the first reporting configuration. The target report is a report corresponding to the first reporting configuration. The target report may be a report that satisfies the first condition (first target information) or a report that does not satisfy the first condition. The second configuration parameter may be the same as the first configuration parameter.

[0138] In addition, a third configuration parameter may be set in configuration information other than the first reporting configuration. The third configuration parameter may instruct the terminal to skip sending a target report on a reporting resource in a fourth reporting configuration. The target report is a report corresponding to the fourth reporting configuration. The target report may be a report that satisfies the first condition (first target information) or a report that does not satisfy 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.

[0139] Optionally, when the target report configuration adopts the second report configuration, the terminal performs a first operation when the first condition is met, including: the terminal performs the first operation when obtaining the second report configuration and meeting the first condition; the second report configuration includes at least one of the following: the first condition, measurement resource configuration information, report configuration index and reporting configuration information.

[0140] The second reporting configuration of the above-mentioned first target information is an additional configuration, a reporting configuration different from the CSI reporting configuration and the LTM-CSI reporting configuration. Specifically, the above-mentioned second configuration report may include at least one of the first condition, measurement resource configuration information, reporting configuration index and reporting configuration information.

[0141] In addition, the embodiment of the present application is different from the network-side device triggering reporting mechanism in the existing related technology, and is also different from the event-triggered mechanism in the existing related technology (see Table 4). Instead, it is triggered by the terminal to specifically execute the first condition and the first operation based on step 301, so that the above-mentioned triggering process is not limited to execution at the L3 layer, but can also be executed at the L1 layer, thereby reducing the resource overhead of beam management.

[0142] Optionally, the first target reference signal includes a reference signal whose measurement result meets a preset threshold.

[0143] 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 a preset threshold, and the above preset threshold can be configured by the network or agreed upon by the protocol.

[0144] Optionally, the first target reference signal includes at least one of the following:

[0145] a first reference signal (RS), where a measurement result of the first RS plus a first offset value is less than or equal to a first threshold, or a measurement result of the first RS within a first time period plus a second offset value is less than or equal to a second threshold, or a measurement result of the first RS within a second time period plus a third offset value is less than or equal to a third threshold, and the number of times is greater than or equal to N1. The first RS is a reference signal corresponding to a beam currently used by the terminal, and N1 is a positive integer.

[0146] a second RS, wherein a measurement result of the second RS minus a fourth offset value is greater than or equal to a measurement result of the first RS;

[0147] a third RS, wherein a measurement result of the third RS within the third time minus a fifth offset value is greater than or equal to a measurement result of the first RS;

[0148] a fourth RS, wherein the number of times that the measurement result of the fourth RS within the fourth time minus the sixth offset value is greater than or equal to the measurement result of the first RS is greater than or equal to N2, where N2 is a positive integer;

[0149] a fifth RS, wherein a measurement result of the fifth RS minus a seventh offset value is greater than or equal to a measurement result of the eighth RS;

[0150] a sixth RS, wherein a measurement result of the sixth RS within the fifth time minus an eighth offset value is greater than or equal to a measurement result of the eighth RS;

[0151] The seventh RS, wherein the number of times that the measurement result of the seventh RS within the sixth time minus the ninth offset value is greater than or equal to the measurement result of the eighth RS is greater than or equal to N3, where N3 is a positive integer.

[0152] In the embodiment of the present application, the first condition can be understood as at least one of the following:

[0153] 1) The measurement result of the RS (first RS) corresponding to the beam currently being used by the terminal plus the first offset value is still lower than the first threshold;

[0154] 2) The measurement result of the RS (first RS) corresponding to the beam currently being used by the terminal plus the second offset value is continuously lower than the second threshold within a first period of time;

[0155] 3) The number of times that the measurement result of the RS (first RS) corresponding to the beam currently being used by the terminal plus the third offset value is lower than the third threshold in the second time is not less than N1;

[0156] The RS corresponding to the beam being used by the terminal in the above conditions 1)-3) includes at least one of the following:

[0157] A Quasi Co-Location (QCL) source reference signal (source RS) of the TCI state of at least one control resource set (CORESET), including at least a QCL-Type D source RS;

[0158] At least one activated TCI state(s) for PDSCH QCL source RS, including at least QCL-Type Dsource RS;

[0159] The QCL source RS of the TCI state indicated by the network-side device includes at least the QCL-Type D source RS;

[0160] The above TCI state applies to at least one of the R15 TCI state configuration framework and the R17 unified TCI state configuration framework.

[0161] Regarding the condition 3) above, the number of times a threshold is satisfied within a preset time (second time) may be used as a condition. The terminal may perform a preset number of measurements within the preset time. For example, periodic measurements (i.e., periodically configuring RS resources) may be performed within the preset time, and the number of measurements may be counted. The number conditions in conditions 6) and 9) below are similar.

[0162] 4) There is at least one second RS whose measurement result after subtracting the fourth offset value is still higher than the measurement result of the RS corresponding to the beam currently being used by the terminal (the first RS);

[0163] 5) The measurement result of at least one third RS minus the fifth offset value is continuously greater than the measurement result of the RS (first RS) corresponding to the beam currently being used by the terminal within a third time period;

[0164] 6) The measurement result of at least one fourth RS minus the sixth offset value is greater than the measurement result of the RS corresponding to the beam currently being used by the terminal (the first RS) for a number of times not less than N2 within the fourth time period;

[0165] 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 being used by the terminal to determine whether the first target reference signal exists. Optionally, the second RS, third RS, and fourth RS may be RSs of neighboring cells or RSs configured by a network-side device.

[0166] 7) There is at least one measurement result of the fifth RS whose value after subtracting the seventh offset value is still greater than the measurement result of the eighth RS;

[0167] 8) There exists at least one measurement result of the sixth RS, the value of which after subtracting the eighth offset value, is continuously greater than the measurement result of the eighth RS within the fifth time period;

[0168] 9) There is at least one measurement result of the seventh RS minus the ninth offset value, and the number of times within the sixth time period that the result is greater than the measurement result of the eighth RS is not less than N3;

[0169] The measurement results of the RS measured in the above conditions 7)-9) are compared with the measurement results of a specific RS (eighth RS) to determine whether the first target reference signal exists. The above-mentioned eighth RS can be an RS configured by the network side device, or it can be the 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 results at the second reporting moment. The second reporting moment is earlier than the first reporting moment, that is, it can be understood that when an RS is found in the subsequent reporting moment that is better than the previous reporting moment, it is considered that the first target RS exists, triggering the execution of the first operation.

[0170] Optionally, each of the fifth RS, sixth RS, and seventh RS may be associated with a different reporting configuration with the eighth RS.

[0171] In the embodiment of the present application, the above-mentioned bias value, threshold, time (start time or duration) and the values ​​of N1, N2, and N3 are all configured or indicated by the network, or specified by the protocol by default.

[0172] In the embodiment of the present application, the first RS to the eighth RS, and the second target reference signal, may be associated with different objects or the same object according to network configuration or protocol agreement.

[0173] Optionally, at least one of the timing advance TA, configuration information and frequency-related information of the target object meets a preset condition.

[0174] In the embodiment of the present application, at least one of the object's TA, configuration information, and frequency-related information is used as a screening condition parameter for the target object. If at least one of the above parameters of the object meets the preset condition, the object is the target object, that is, there is a target object that triggers the first operation.

[0175] Optionally, the target object satisfies at least one of the following:

[0184] 2) The target object's TA can be obtained through UE-based TA measurement and calculation;

[0185] The TA value of the target object is obtained based on measurement and calculation by the terminal and must meet at least one of the following conditions:

[0186] The value of the first parameter in the configuration information for layer 1 or layer 2 triggered handover corresponding to the target object is the same as the value of the first parameter in the configuration information corresponding to the current service object; the first parameter is used to indicate whether the terminal can perform TA measurement and calculation;

[0187] The number of the target objects does not exceed the first UE capability, where 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.

[0188] 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;

[0189] 4) The SSB frequency information of the target object is the same as the frequency information in a measurement object (Meas Object) currently configured by the terminal;

[0190] 5) The target object is a known object (known);

[0191] Taking a known cell as an example, a known cell is a neighboring cell or a candidate cell that satisfies at least one of the following conditions:

[0192] The UE performs L3 measurements on this cell over a period of time;

[0193] The SSB of the cell used for L1 measurement is detectable.

[0194] Optionally, the terminal sends first target information to the network side device, including at least one of the following:

[0195] Sending first target information on a first resource; the first resource is configured, instructed, or scheduled by the network side device;

[0196] The first information is sent on the second resource, and the second information is sent on the third resource, wherein 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 the configuration, indication, scheduling, and terminal indication of the network side device.

[0197] In the embodiment of the present application, the terminal sending the first target information to the network side includes the terminal sending the target information on the target uplink resource, including but not limited to at least one of the following:

[0198] a) the terminal sends target information on a first uplink resource configured, instructed, or scheduled by the network side;

[0199] b) The terminal sends the first information on the 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 the configuration, indication, scheduling, and terminal indication of the network side device.

[0200] The terminal can perform reporting of the first target information based on the network side device configuration, or indication, or scheduling, or at least one of the resources indicated by the terminal. The above reporting can be performed using the first uplink resource configured, indicated, or scheduled by the network side, or the first target information can be divided into two categories of information (first information and second information) and reported separately.

[0201] Optionally, the first information includes at least one of the following:

[0202] information indicating whether the second information exists;

[0203] size information of the second information;

[0204] Indication information of the third resource;

[0205] an identifier 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;

[0206] a measurement result 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;

[0207] The number of at least one of the first target reference signal and the second target reference signal carried in the second information.

[0208] In an embodiment of the present application, the first information of the first target information can be reported on the second resource. Optionally, the above-mentioned first information can be understood as the content indication and resource indication of the first target information, and the second information can be understood as the content of the first target information (relevant information of the first target reference signal, relevant information of the second target reference signal, transmission configuration indication TCI related information and at least one of beam auxiliary information) itself.

[0209] The first target information reported on the first resource can be understood to include a content indication of the first target information and the content of the first target information itself. The content of the first target information itself can also be understood to include only the content of the first target information itself.

[0210] The first information includes but is not limited to at least one of the following:

[0211] a) Whether the second information exists; for example, indicated by 1 bit, i.e., 0 indicates no information and 1 indicates yes information;

[0212] b) the size of the second information;

[0213] c) resource indication of the third uplink resource;

[0214] d) an identifier 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;

[0215] e) a measurement result 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;

[0216] f) the number of at least one of the first target reference signal and the second target reference signal carried in the second information.

[0217] The second information includes part or all of the content of the first target information except the first information;

[0218] One possible scenario 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 used. In this case, when the second information does not exist, the second information can be indicated as not existing only through the second resource, so that the network-side device can use the third resource for transmission purposes other than for other purposes. That is, in this embodiment of the application, by dynamically indicating the resource that carries the second information, it is possible to achieve the purpose of rational resource utilization.

[0219] 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 indicating a specific number of bits, or by indicating the order after quantization of a specific number of bits. For example, 0 to 79 bits are indicated by 3 bits, where 0 represents 0 to 9, 1 represents 10 to 19, and so on, 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.

[0220] Optionally, the first target information is carried in at least one of the following ways:

[0221] The first target information is used as at least part of the CSI part 2;

[0222] The first information is used as at least part of the CSI part 0, and the second information is used as at least part of the CSI part 1 or part 2;

[0223] The first information serves as at least part of the CSI part 1, and the second information serves as at least part of the CSI part 2.

[0224] In an embodiment 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:

[0225] 1) The first target information is used as part of CSI part 2;

[0226] 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;

[0227] 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; wherein CSI part 0 is newly added UCI information;

[0228] Optionally, the first part may be CSI part 1, and the second part may be CSI part 2;

[0229] Optionally, when performing resource mapping, the terminal maps the UCI sequence to the resource for transmission in the order of the first part first and the second part later. That is, the content of the first information is read first, from which the existence of the second information or the resource location of the second information can be determined, thereby improving the efficiency of information acquisition.

[0230] Optionally, the method further includes:

[0231] When the transmission resources of the first target information and the transmission resources of the third information overlap in the time domain, the terminal determines the priority order of the first target information and the third information according to a first preset rule.

[0232] In an embodiment of the present application, when there is a conflict between the transmission resources of the first target information reported by the terminal and other information (third information), the transmission priority between the conflicting information can be determined based on a preset rule (first preset rule).

[0233] It can be understood that the above-mentioned overlap in the time domain can be understood as partial or complete overlap of time domain resources.

[0234] When the frequency domain and the spatial domain overlap, other preset rules may be used to determine the priority between conflicting information.

[0235] Optionally, the third information includes any one of the following:

[0236] CSI report, LTM-CSI report, second target information;

[0237] The second target information is target information having at least some characteristics different from those of the first target information.

[0238] In the embodiment of the present application, the conflicting information with the first target information may be at least one of the CSI report, the LTM-CSI report, and the second target information.

[0239] The above-mentioned 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).

[0240] The above LTM-CSI report can also be described as an LTM report.

[0241] The above-mentioned CSI report and LTM-CSI report can be understood as reports triggered by network-side devices.

[0242] In an embodiment of the present application, the first target information is the target information sent by the terminal when the first condition is satisfied, and the second target information can be understood as other target information that is different from the first target information and is sent by the terminal when the first condition is satisfied, wherein the second target information is target information that is different from at least some of the characteristics of the first target information. The sending conditions, content, and transmission method of the second target information are similar to those of the first target information, but at least part of the characteristic information included in the second target information (for example, at least one of the content contained 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.

[0243] Optionally, the first preset rule includes at least one of the following:

[0244] Determining the priority of the first target information and the third information based on the priority of the network configuration;

[0245] Determining the priority of the first target information and the third information according to a preset priority calculation formula;

[0246] The priority of the report carrying the first target information is higher than the priority of the LTM-CSI report;

[0247] The priority of the report carrying the first target information is higher than the priority of the CSI report;

[0248] The priority corresponding to the first information of the second target information is higher than the priority corresponding to the second information of the first target information;

[0249] The priority corresponding to the first information of the first target information is higher than the priority corresponding to the second information of the second target information;

[0250] The priority corresponding to the first information of the first target information is higher than the priority corresponding to the second information of the first target information;

[0251] The priority corresponding to the first information of the second target information is higher than the priority corresponding to the second information of the second target information;

[0252] The priority of the report carrying the third target information is higher than the priority of the report carrying the fourth target information; wherein 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;

[0253] The third target information satisfies at least one of the following conditions:

[0254] At least one measurement resource associated with the target object exists in the measurement resources associated with the report carrying the third target information;

[0255] The third target information is associated with at least one target object;

[0256] The reporting configuration corresponding to the third target information is the LTM-CSI reporting configuration;

[0257] 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;

[0258] The fourth target information satisfies at least one of the following conditions:

[0259] The measurement resources associated with the report carrying the fourth target information are only associated with the current service object of the terminal;

[0260] The fourth target information is associated with the current service object of the terminal;

[0261] The reporting configuration corresponding to the fourth target information is a CSI reporting configuration;

[0262] 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.

[0263] In the embodiment of the present application, the priority rule (first preset rule) may be pre-configured by the network-side device. For example, the first priority value of different reports may be explicitly configured by the network. Further, optionally, the higher the first priority value, the higher the priority, or the lower the first priority value, the higher the priority.

[0264] The above priority rule (first preset rule) may also be calculated based on a preset priority formula, for example, the CSI report priority formula mentioned above may be used.

[0265] The above-mentioned first preset rule can also pre-specify that the priority of the report carrying target information is higher than the priority of the LTM report; or the priority of the report carrying 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.

[0266] The above-mentioned first preset rule can also pre-specify that the priority corresponding to the first information is higher than the priority of the second information. The above-mentioned first information and second information can be information in different target information or information of 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 event of a conflict between the first target information and the second target information, the first information carried by both can be transmitted first.

[0267] In an embodiment of the present application, when the first target information and the second target information conflict, the priority of the related information of the first target information and the second target information can be judged first, so as to determine the third target information with higher priority and the fourth target information with lower priority from the first target information and the second target information, and the priority of the report carrying the third target information is higher than the priority of the report carrying the fourth target information.

[0268] A specific screening rule may be that the report carrying the third target information satisfies at least one of the following conditions:

[0269] There is at least one measurement resource-associated target object in the measurement resources associated with the report;

[0270] The third target information includes at least one piece of information associated with at least one target object, for example, the second target reference signal is a reference signal associated with the target object, or a TCI state associated target object, or a QCL source RS associated target object of the TCI state;

[0271] The report association report configuration is LTM-CSI-ReportConfig (corresponding to the case where the target information adopts the first report configuration and the LTM-CSI report configuration);

[0272] The first condition corresponding to the third target information has a higher priority; optionally, the priority of the first condition is configured or indicated by the network, or specified by a protocol;

[0273] A specific screening rule may be that the report carrying the fourth target information satisfies at least one of the following conditions:

[0274] All measurement resources associated with the report are only associated with the current service object;

[0275] The fourth target information is associated with the current service object, for example, the second target reference signal, TCI state, etc.;

[0276] The report-associated report configuration is CSI-ReportConfig (corresponding to the case where the target information adopts the first report configuration and the CSI report configuration is adopted);

[0277] 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 specified by the protocol.

[0278] Optionally, the method further includes at least one of the following:

[0279] The terminal performs data transmission according to target beam information corresponding to the first target information after receiving a first preset time of a first physical downlink control channel (PDCCH) sent by a network side device, wherein a hybrid automatic repeat request (HARQ) process identifier scheduled by the first PDCCH is the same as a target physical uplink shared channel (PUSCH), a new data indicator (NDI) in the first PDCCH is flipped relative to the NDI in the PDCCH that schedules the target PUSCH, the target PUSCH is a PUSCH that carries the first target information, and the first preset time is greater than or equal to 0;

[0280] After receiving the second preset time of 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.

[0281] 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:

[0282] After the terminal sends the target information on the PUSCH, after a first preset time of receiving a PDCCH with a scheduling HARQ process ID that is the same as the PUSCH but with an NDI flipped, the terminal will use the beam information indicated in the first target information to receive downlink signals and data, and / or send uplink signals and data; the above-mentioned first preset time is greater than or equal to 0. When the first preset time is equal to 0, it can be considered that the target beam takes effect and is used when the first PDCCH is received. When the first preset time is greater than 0, it can be considered that the target beam takes effect and is used after the preset time length after the first PDCCH is received.

[0283] 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, 1 indicates beam switching), and after the second preset time when the switching indication information indicates beam switching (i.e., receiving the second PDCCH), the terminal will use the beam information indicated in the first target information to receive downlink signals and data, and / or send uplink signals and data; the above-mentioned second preset time is greater than or equal to 0. When the second preset time is equal to 0, it can be considered that the target beam takes effect and is used when the second PDCCH is received. When the second preset time is greater than 0, it can be considered that the target beam takes effect and is used after the preset time after the second PDCCH is received.

[0284] The beam switching indication information may be carried by a new DCI format, or indicated by adding a new field or using reserved bits in the existing DCI format.

[0285] It can be understood that the terminal can use the current beam to receive the above-mentioned first PDCCH and second PDCCH, or use the target beam information corresponding to the first target information to receive the above-mentioned first PDCCH and second PDCCH.

[0286] In an embodiment of the present application, the beam and the target beam are generally 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.

[0287] In an embodiment of the present application, the terminal sends first target information (carrying beam-related information) to the network side device. When the network side device feeds back PDCCH, the target beam negotiation can be achieved. This process is significantly different from the beam activation and indication process in the related technology (see Figure 2), that is, the timeline of beam management or beam switching is improved, which can effectively reduce the beam switching delay.

[0293] determining the target beam information according to a measurement result of the second target reference signal;

[0294] The target beam information is determined according to the arrangement order of the multiple TCI related information.

[0295] In this embodiment of the present application, when the number of information related to the first target reference signal, the information related to the second target reference signal, or the TCI related information carried in the first target information is 1, the terminal side directly determines the beam information based on the first target information for receiving downlink signals and data, and / or sending uplink signals and data;

[0296] When the first target information carries relevant information of the first target reference signal, or relevant information of the second target reference signal, or the number of TCI related information greater than 1, the terminal side determines the target beam information according to the second preset rule for receiving downlink signals and data, and / or sending uplink signals and data.

[0297] Exemplarily, the second preset rule includes but is not limited to at least one of the following:

[0298] determining target beam information according to a first target reference signal arranged first;
