Description

Technical Field

[0001] This application belongs to the field of communication technology, and specifically relates to a method, apparatus, terminal and network-side equipment for determining a measurement reporting mode. Background Technology

[0002] Beam management mechanisms in related technologies typically detect beam quality through beam measurements and reporting triggered by network-side devices. These devices then configure, activate, and indicate beams based on the measurement results reported by the terminal. With the development of massive MIMO technology and the expansion of high-speed mobile scenarios, beamwidths are narrower and change rapidly with movement. To ensure real-time beam tracking, network-triggered beam management mechanisms require frequent beam reporting. Periodic beam reporting increases uplink resource overhead, while aperiodic beam reporting based on aperiodic CSI-RS requires activating the aperiodic CSI-RS before measurement and reporting, resulting in significant overall latency.

[0003] Related technologies have supported UE-triggered mobility management (i.e., event-triggered measurement and reporting), but they only support L3 measurement and report it at the RRC layer. For L1 measurement and reporting, they currently only support periodic, semi-persistent, or non-periodic network triggering, while the terminal triggering mechanism is not yet clear, meaning that the beam management flexibility of L1 measurement is poor.

[0069] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0070] Regarding event triggering measurement and reporting

[0071] In the current protocol, event-triggered measurements and reported measurements are L3 measurement results, primarily used to assess cell quality for handover purposes. The UE will only perform L3 measurements on neighboring cells when the quality of the serving cell falls below a certain threshold (i.e., event A2 in Table 1); and the UE will only perform L3 reporting when the measurement results of a neighboring cell meet a certain event (i.e., one of those in Table 1). For the event definitions in Table 1, L3 reporting currently associates a measurement configuration (MeasConfig) with a reporting configuration (ReportConfig) and a measurement object (MeasObject). The ReportConfig is associated with an event configuration. In L3 reporting, to enable the network to determine the event corresponding to the reported content, in addition to the L3 measurement results, the terminal also reports the measurement configuration identifier (MeasConfig id). Specific event definitions are shown in Table 1.

[0072] Table 1 Event Definitions

[0073]

[0074]

[0075] The parameters in Table 1 are explained as follows:

[0076] Ms: Serving cell measurement results, without considering any offset;

[0077] Mn: Neighbor cell measurement results, without considering any offset;

[0078] Ofn: Specific offset of the neighboring cell measurement object;

[0079] Ocn: Neighboring cell-level specific offset;

[0080] Mp: SpCell (primary serving cell) measurement result, without considering any offset;

[0081] Ofp: SpCell measures a specific offset of an object;

[0082] Ocp: SpCell cell-level specific offset;

[0083] Hys: The hysteresis parameter of the event;

[0084] Off: The offset parameter of the event;

[0085] Mi: Interference measurement result;

[0086] Thresh: Threshold.

[0087] Regarding beam measurement

[0088] Analog beamforming is transmitted across the full bandwidth, and each polarization element on the panel of each high-frequency antenna array can only transmit an analog beam in a time-division multiplexed manner. The beamforming weights of the analog beam are achieved by adjusting the parameters of devices such as the RF front-end phase shifter.

[0089] Currently, in academia and industry, the training of simulated beamforming vectors is usually carried out using a polling method. That is, each element of each antenna panel in each polarization direction sends training signals (i.e., candidate beamforming vectors) sequentially at a predetermined time in a time-division multiplexing manner. After measurement, the terminal feeds back a beam report, which is used by the network side to implement simulated beam transmission in the next transmission service.

[0090] Currently, related technologies only support beam measurement using Channel State Information-Reference Signal (CSI-RS) or Synchronization Signal and PBCH block (SSB). The CSI-RS used for beam measurement typically has only 1-2 ports. The SSB is a periodic reference signal, while the CSI-RS used for beam measurement can be periodic, semi-continuous, or aperiodic.

[0091] Beam measurement is divided into Layer 1 (L1) beam measurement and Layer 3 (L3) beam measurement. L1 beam measurement in Releases 15 and 16 was limited to the serving cell. Release 15 only supported L1 Reference Signal Received Power (RSRP) measurement, while Release 16 introduced L1 Signal to Interference plus Noise Ratio (SINR) to incorporate inter-cell or inter-user interference into the beam measurement. Release 17, under the Cross-Cell Beam Management and Cross-Cell Multitransmitter / Receiver Nodes (MCN) project, supported L1 beam measurement of neighboring cells that are on the same frequency and synchronized with the current serving cell. Release 18, under the Mobility Enhancement project, supported L1 beam measurement of neighboring cells that are asynchronous and on different frequencies. Both currently only support 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 then selects a beam to report based on the measurement results.

[0092] Regarding beam reporting

[0093] Currently, the protocol supports L1-RSRP / L1-SINR as the reported measurement quantities for L1 beam reports triggered by network-side devices. Beam reporting can be done in two ways: group-based and non-group-based. For non-group-based beam reporting, the terminal selects up to four beams from all measurement resources associated with the L1 beam report configured on the network side, based on the reported measurement quantities. 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 quantities.

[0094] In the existing protocol, if the report quantity field in the CSI Report Config parameter is configured as "cri-RSRP", "cri-SINR", "ssb-Index-SINR", or "ssb-Index-RSRP", it indicates that the current CSI report is a beam report. Furthermore, when the groupBasedBeamReporting field is enabled, the UE can only report one beam: containing two Channel Measurement Resource (CMR) identifiers and their corresponding L1-RSRP / L1-SINR values. The CMR identifiers include Channel State Information - Reference Signal Resource Indicator (CRI) or SSB Resource Indicator (SSBRI). When the groupBasedBeamReporting field is disabled, the UE may report the CMR identifiers and their corresponding L1-RSRPs for four beams. When the number of reported beams is greater than 1, all L1-RSRP / L1-SINR values ​​other than the maximum value are reported using a differential method compared to the maximum value. The specific mapping rules (L1-RSRP) for CSI-reported Uplink Control Information (UCI) are shown in Tables 2 and 3, and L1-SINR follows a similar pattern. It is important to note that the CRI / SSBRI positions correspond to the RSRP positions; CRI / SSBRI#1 corresponds to RSRP#1, and RSRP#1 is the maximum value among the four RSRP values.

[0095] Table 2. UCI mapping order reported by Release 15 / 16 L1 beam

[0096]

[0097] Table 3 UCI Bit Overhead

[0098]

[0099] The reference signal RS identifier and the number of UCI bits for L1-RSRP are shown in Table 3. L1-SINR is similar. 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.

[0100] In the Release 17 multi-transmitter-receiver node project, the group-based beam reporting method has been enhanced. The terminal can select up to 4 pairs of beams that the UE can receive simultaneously from the measurement resources configured by the network for reporting. Different beams in each pair of beams correspond to different transmit-receiver nodes, thereby ensuring that the network can send the pair of beams simultaneously.

[0101] In the Release 18 Layer 1 or Layer 2 Triggered Mobility (L1 / L2-Triggered Mobility, LTM) project, L1 reporting for handover, namely ltm-CSI-ReportConfig, was introduced. In a single L1 report for handover, a terminal can report up to 4 cells, with each cell reporting 4 beam measurement results, for a maximum of 16 beams and their corresponding measurement results.

[0102] In the current standard, the content of L1 beam reports is placed in CSI part I, and the UCI bit length is fixed.

[0103] Regarding the Unified Transport Configuration Instruction Framework (TCI framework)

[0104] The Transmission Configuration Indicator (TCI) framework supports two modes: joint and separate. In joint mode, the uplink and downlink channels and the reference signal have the same beam, while in separate mode, the downlink channel and the downlink reference signal have the same beam, and the uplink channel and the uplink reference signal have the same beam, but the uplink and downlink beams are different.

[0105] For joint mode, the network side only needs to configure one TCI state list, and then determine the UE's beam through activation by the Media Access Control Control Element (MAC CE) and indication by Downlink Control Information (DCI). For separate mode, the network side needs one TCI state list for downlink channels and downlink reference signals, and one TCI-UL-State list for uplink channels and uplink reference signals. In separate mode, TCI state activation and indication are performed by MAC CE in the form of beam pairs (i.e., one TCI state + one TCI-UL-State), and then the DCI determines a beam pair from the activated beam pairs.

[0106] Considering that some channels and signals have high robustness requirements but not high peak transmission requirements, the Unified TCI framework divides channels and signals into two parts. For the first part, the QCL assumptions (for downlink) or spatial relationships (for uplink) are determined based on the network-indicated unified TCI state. For the second part, whether the QCL assumptions (for downlink) or spatial relationships (for uplink) are determined based on the network-indicated unified TCI state depends on the RRC configuration and whether the network-indicated unified TCI state is associated with neighboring cells. The specific rules are as follows:

[0107] 1. If the RRC configuration information "followUnifiedTCI-State" corresponding to the second part of the signal and channel is enabled, and the unified TCI state indicated by the network is associated with the serving cell, then the QCL assumption (for downlink) or spatial relationship (for uplink) of the second part of the signal and channel is determined according to the unified TCI state indicated by the network.

[0108] 2. If the RRC configuration information "followUnifiedTCI-State" corresponding to the second part of the signal and channel is enabled, and the unified TCI state indicated by the network is associated with neighboring cells, then the QCL assumption (for downlink) or spatial relationship (for uplink) of the second part of the signal and channel is determined by the TCI state / TCI-UL-State indicated by the network separately for the second part of the signal and channel.

[0109] 3. If the RRC configuration information corresponding to the second part of the signal and channel does not include the higher layer configuration parameter "followUnifiedTCI-State", then the QCL assumption (for downlink) or spatial relationship (for uplink) of the second part of the signal and channel is determined according to the TCI state / TCI-UL-State indicated by the network separately for the second part of the signal and channel;

[0110] With the development of massive MIMO technology and the expansion of high-speed mobile scenarios, the narrow beamwidth and rapid beam changes with movement have led to problems with network-triggered beam management mechanisms, which suffer from high resource overhead and large beam switching delays.

[0111] Related technologies already support UE-triggered beam management mechanisms (i.e., event-triggered measurement and reporting). However, event-triggered measurement and reporting only supports L3 measurements, which are reported at the RRC layer. For L1 measurements and reporting, currently only periodic, semi-persistent, or aperiodic network-triggered forms are supported; terminal-triggered mechanisms are not yet supported. This means that UE-triggered beam management based on L1 measurements cannot be flexibly implemented. Therefore, the process and signaling design for terminal-triggered L1 reporting need further definition.

[0112] The following description, in conjunction with the accompanying drawings, details the method, apparatus, terminal, and network-side equipment for determining the measurement reporting mode provided in this application, through some embodiments and application scenarios.

[0113] See Figure 2 , Figure 2 This is a flowchart of a method for determining a measurement reporting mode according to an embodiment of this application, used in a terminal, such as... Figure 2 As shown, the method includes the following steps:

[0114] Step 201: The terminal obtains the target information.

[0115] Step 202: The terminal determines the target mode based on the target information. The target mode is the reporting mode of the layer 1 beam report triggered by the terminal.

[0116] The target information includes at least one of the following:

[0117] The first high-layer parameter configured for network-side devices;

[0118] The first parameter determined by the terminal;

[0119] Whether the terminal receives the first downlink control signaling (DCI).

[0120] In related technologies, the mechanism for L1 beam reporting mode triggered by the terminal has not yet been determined, which means that beam management of L1 measurement can only be triggered by network-side devices. On the one hand, this results in poor flexibility of beam management, and on the other hand, it also results in large latency of beam management and high overhead of reporting resources.

[0121] In this embodiment, the beam reporting mode of L1 triggered by the terminal is determined based on specific target information, thereby improving the flexibility of beam management. Replacing or assisting network-side equipment in triggering beam reporting with terminal triggering can also improve the rationality of beam management, thereby reducing beam management latency and saving reporting resource overhead.

[0122] Specifically, in this embodiment of the application, the specific beam report reporting mode is determined based on the first higher-layer parameters configured by the network-side device, the first parameters determined by the terminal, and whether the terminal receives the first downlink control signaling (DCI). Determining the reporting mode based on the above target information can be understood as the terminal judging the specific reporting mode based on the information provided by the network side and / or the information determined by itself.

[0123] In this embodiment of the application, the above-mentioned target mode can also be described as a target reporting mode.

[0124] Optionally, when the target information includes first higher-layer parameters configured by the network-side device, the terminal determines the target mode based on the target information, including at least one of the following:

[0125] The target mode is determined based on the target mode indication information of the first high-level parameter;

[0126] The target mode is determined based on whether the second uplink resource is configured according to the first high-layer parameter;

[0127] The target mode is determined based on the second uplink resource configured according to the first high-layer parameter;

[0128] The target mode is determined based on the distance between the first uplink resource configured by the first high-level parameter and the second uplink resource configured by the first high-level parameter.

[0129] In this embodiment, the network-side device directly displays the target mode through a first higher-layer parameter (e.g., RRC parameter), and the terminal performs reporting according to the target mode. Alternatively, the target mode can be implicitly indicated by other parameters in the first higher-layer parameter, for example, by whether a second uplink resource is configured, where the second uplink resource is used to send the first report (the first report is a beam report). This means that the first report can be sent using the second uplink resource if it is configured, and otherwise sent using other methods if it is not configured. If the second uplink resource is already configured, the decision to use it to send the first report (i.e., determine the target mode) can also be determined based on the specific parameters of the second uplink resource; or by the correlation between parameters, for example, by the distance between the first and second uplink resources.

[0130] Optionally, if the target information includes the first parameter determined by the terminal, the terminal determines the target mode based on the target information, including at least one of the following:

[0131] The target mode is determined based on the latency information determined by the terminal;

[0132] The target mode is determined based on the latency requirements determined by the terminal.

[0133] In this embodiment of the application, the terminal can determine the target mode based on the parameters it can obtain. For example, it can determine the signal processing latency based on its own capabilities, or determine the latency requirement based on the service type, and select a suitable target mode. For example, if the latency requirement is low, the target mode with relatively low latency can be selected.

[0134] The above latency parameters are only examples of the first parameters. In this embodiment, the terminal can also determine the target mode based on other parameters that it can obtain (e.g., the reliability of data transmission, the size of the first report, and the size of available uplink resources).

[0135] Optionally, if the target information includes whether the terminal receives the first DCI, the terminal determines the target mode based on the target information, including:

[0136] After the terminal sends the first information on the first uplink resource, it determines the target mode based on whether the terminal receives the first DCI.

[0137] The second uplink resource is used to carry the first report; the first uplink resource is earlier than the second uplink resource.

[0138] In this embodiment of the application, after sending the first information (related information of the first report), the terminal can determine the target mode based on whether it receives the first DCI, that is, determine the target mode based on the specific DCI instruction of the network-side device.

[0139] Optionally, the method further includes at least one of the following:

[0140] The terminal periodically sends the first information on the first uplink resource;

[0141] When the conditions corresponding to the first event are met, the terminal sends the first information on the first uplink resource.

[0142] Wherein, the first information is related to the first report, the first report is a beam report that meets the conditions corresponding to the first event, and the first event is the triggering event of the first report.

[0143] In this embodiment of the application, the first report may be a layer 1 beam report triggered by the terminal. The layer 1 (L1) beam report triggered by the terminal may be triggered based on a preset event (which may be described as a first event). For example, it may be determined whether the conditions corresponding to the event are met based on the measurement results of the RS corresponding to the beam currently being used by the terminal and / or the measurement results of the RS corresponding to the candidate beam, thereby determining whether the L1 beam report is triggered by the terminal.

[0144] The terminal sends relevant information about the first report on the first uplink resource. This information can be understood as parameters related to the first report, or it can be an indication of whether a first report exists. It is understandable that even if the conditions corresponding to the event are not met, and no beam report needs to be reported, the first information can still be reported (e.g., indicating in the first information that no first report exists).

[0145] The aforementioned first information can be reported when the conditions corresponding to the event are met, or it can be reported periodically based on the first uplink resource cycle.

[0146] In other words, optionally, both the first message and the first report exist and are sent only when the event is satisfied; optionally, the first message is independent of whether the event is satisfied and is sent periodically, and the first message provides information on whether the event is satisfied or whether the first report exists; the first report is sent only when the event is satisfied.

[0147] Optionally, the first uplink resource is the uplink resource configured by the network-side device.

[0148] In this embodiment of the application, the aforementioned first uplink resource can be further determined based on the first higher-layer parameters configured by the network-side device.

[0149] Optionally, the terminal periodically transmits first information on the first uplink resource, including:

[0150] If the first condition is met, the terminal does not send the first information in the first uplink time slot;

[0151] The first condition includes at least one of the following:

[0152] There are no valid downlink slots prior to the first downlink slot;

[0153] The first downlink time slot is not a valid downlink time slot;

[0154] The first uplink time slot is the time slot where the first uplink resource is located, and the first downlink time slot is the downlink time slot closest to the time point of a first preset duration before the downlink time slot corresponding to the first uplink time slot.

[0155] In this embodiment of the application, the terminal periodically sends first information on the first uplink resource. When a specific condition (the first condition) is met, the terminal may not send the first information in the current period when the condition is met, thereby avoiding invalid reporting and reducing terminal power consumption.

[0156] Without considering the first condition, the terminal periodically sends the first information on the first uplink resource. This can be understood as periodically sending the first information on the first uplink resource. One resource opportunity of the first uplink resource is in the first uplink time slot, and the first uplink time slot has a corresponding downlink time slot (described as the second downlink time slot). The downlink time slot closest to the time point of the first preset duration before the second downlink time slot is described as the first downlink time slot. In this application embodiment, the validity of the first downlink time slot or whether there is a valid downlink time slot before the first downlink time slot is determined. When there is no valid downlink time slot before the first downlink time slot and / or the first downlink time slot is not a valid downlink time slot, it can be understood that there will be no valid measurement information in the current period. Therefore, the reporting of the first information is not performed, thereby improving the effectiveness of the first information reporting and saving uplink resources.

[0157] In this embodiment of the application, the terminal may send the first information on the first uplink slot when there is a valid downlink slot before the first downlink slot and / or the first downlink slot is a valid downlink slot.

[0158] For ease of understanding, the following is an example of the periodic reporting of first information based on the first condition:

[0159] The terminal periodically sends first information on the first uplink resource;

[0160] The terminal expects the first downlink slot to be a valid time slot.

[0161] When the first condition is met, the terminal does not send the first information on the first uplink slot;

[0162] The first condition includes at least one of the following:

[0163] If there is no valid downlink slot before the first downlink slot;

[0164] The first downlink slot is not a valid downlink slot;

[0165] The first uplink slot is the slot where the first uplink resource is located.

[0166] The correspondence between the first uplink time slot and the second downlink time slot can be determined in the following way:

[0167]

[0168] Where n' is the first uplink slot, n is the second downlink slot, and μ DL and μ UL The SCS coefficients for the downlink and uplink are respectively. μ offset,UL μ offset,DL This refers to the time slot conversion factor for CA scenarios, and its value can be determined by higher-level configuration parameters. This indicates rounding down to the nearest integer.

[0169] The first preset duration can be X ms or X time slots. The first downlink slot is the downlink slot X ms / slot closest to the second downlink slot corresponding to the first uplink slot. The value of X is specified by the protocol or configured by the network.

[0170] The value of X can include at least one of the following:

[0171] 1) Reference resource;

[0172] The value of Reference resource includes at least one of the following:

[0173]

[0174]

[0175] Z′ represents the time required for terminal CSI processing. The number of symbols in each slot;

[0176] 2) Among them, K offset and These are configuration parameters for higher-level systems.

[0177] In this embodiment of the application, a valid downlink time slot can be understood as:

[0178] This time slot includes at least one downlink symbol or flexible symbol configured by a higher layer;

[0179] This time slot was not included in the measurement interval configured in the network.

[0180] In this embodiment of the application, for the periodic reporting of first information (e.g., used to inform the network whether an event has been satisfied and the corresponding report payload size), a mechanism based on the validity of the first downlink time slot is used to avoid invalid reporting of the first information if there is no valid measurement of SSB or CSI-RS before the first information is reported; thus improving the effectiveness of information reporting.

[0181] Optionally, the terminal determines the target pattern based on the target information, including:

[0182] The terminal determines at least one of the first mode and the second mode as the target mode based on the target information;

[0183] Both the first mode and the second mode are reporting modes for the beam report.

[0184] In this embodiment of the application, several reporting modes can be preset (taking the first mode and the second mode as examples). The determination of the target mode can be understood as selecting the target mode from the preset modes.

[0185] To facilitate understanding, and in conjunction with the aforementioned description of target information, the process for determining the target pattern is illustrated below:

[0186] Method 1: Explicitly determine through the high-layer parameters configured on the network-side devices;

[0187] Specifically, a high-level parameter indicates the target mode as the first mode and / or the second mode; or,

[0188] The first and second modes are indicated by two high-level parameters respectively, but the two high-level parameters are not configured at the same time, or are allowed to be configured at the same time but cannot both be configured as enabled.

[0189] Method 2: Implicitly determined through higher-layer parameters configured on the network-side device; specifically, the target mode is determined by whether the network-side device is configured with a second uplink resource, where the second uplink resource is the uplink resource used to carry the first report, and the first report is a beam report triggered by the terminal after meeting certain conditions. If the network side is configured with the second uplink resource, the terminal determines the target mode as the second mode; otherwise, the target mode is the first mode.

[0190] The target mode is determined by the second uplink resource parameters configured on the network side. For example, if the second uplink resource period is greater than a preset threshold, the first mode is determined as the target mode; otherwise, the second mode is determined as the target mode.

[0191] Method 3: The terminal determines the target mode itself. Specifically, the terminal can determine the target mode based on the network configuration of the second uplink resource and from the perspective of latency. For example, if the terminal finds that the period of the second uplink resource is relatively large (greater than or equal to the first preset threshold) and / or the distance from the first uplink resource is relatively far (greater than or equal to the second preset threshold), then the first mode is determined as the target mode; otherwise, the second mode is determined as the target mode.

[0192] Furthermore, when the target mode is determined by the terminal, the terminal reports or indicates the target mode to the network side on the first uplink resource. Here, the first uplink resource is a resource configured or indicated by the network, and the first uplink resource is earlier than the second uplink resource. Specifically, the target mode can be explicitly indicated by 1 bit, or implicitly indicated by other fields.

[0193] Method 4: After the terminal sends the first information on the first uplink resource, if the first DCI is detected within a certain period of time, the terminal determines the target mode as the first mode; otherwise, it determines the target mode as the second mode.

[0194] Optionally, the first DCI is used to indicate or schedule a third uplink resource, which is an uplink resource used to carry the first report, and the first report is a beam report triggered by the terminal after meeting the conditions.

[0195] The length of the time period is specified by network configuration or protocol.

[0196] Optionally, the first information includes at least one of the following:

[0197] Is there at least one instruction that is satisfied immediately?

[0198] An indication message that at least one first event has been met;

[0199] The payload size of the first report;

[0200] The configuration identifier of the first report;

[0201] Component carrier identifier;

[0202] Reporting condition identifier;

[0203] Target pattern indication information;

[0204] Target RS type;

[0205] The resource identifier of the second uplink resource, which is used to carry the first report.

[0206] In this embodiment of the application, the first information includes at least one of the following: whether there is an indication that at least one first time is satisfied, an indication that at least one event is satisfied, the reported payload size, the report configuration identifier, the component carrier (CC) identifier, the condition identifier, the target mode indication information, the target RS type, and the resource identifier of the second uplink resource.

[0207] Optionally, in this embodiment of the application, the payload size of the first report may be the beam report payload size determined according to the target RS type.

[0208] Optionally, in this embodiment of the application, the payload size of the report can be indicated in the following ways:

[0209] The network configuration or protocol specifies a quantization table, in which A0 represents a payload size of 0, A1 represents a payload size of 1 to x1 bits, A2 represents a payload size of x1 to x2 bits, and so on, Ai represents a payload size of xi-1 to xi bits, where xi is the maximum value of the payload size.

[0210] Optionally, if the target mode includes the first mode, the method further includes: the terminal sending the first report according to the third uplink resource indicated by the first downlink control signaling (DCI);

[0211] And / or, if the target mode includes a second mode, the method further includes: the terminal sending the first report according to a second uplink resource, wherein the second uplink resource is an uplink resource configured by a network-side device.

[0212] In this embodiment of the application, the first mode may be the reporting mode of the reported resources determined according to the first DCI instruction or scheduling, and the second mode may be the reporting mode of the reported resources determined according to the network side configuration.

[0213] Optionally, the terminal sends the first report based on the third uplink resource indicated by the first downlink control signaling (DCI), including:

[0214] The terminal determines the third uplink resource from the fourth uplink resource configured by the network-side device based on the first indication information in the first DCI.

[0215] The terminal sends the first report based on the third uplink resource.

[0216] In this embodiment of the application, the terminal determines the uplink resource (third uplink resource) carrying the first report based on the first indication information in the first DCI. Optionally, at least a portion of the fourth uplink resources pre-configured by the network-side device can be selected as the third uplink resource.

[0217] Optionally, the first indication information is indicated by at least one of the following fields in the first DCI:

[0218] Third uplink resource indication field;

[0219] Physical Uplink Control Channel (PUCCH) Resource Indication Field;

[0220] Physical Downlink Shared Channel Hybrid Automatic Repeat Request (PDSCH-to-HARQ) Feedback Time Indication Field;

[0221] Channel State Information (CSI) Request Field;

[0222] Time-Domain Resource Allocation (TDRA) domain;

[0223] Modulation and coding scheme (MCS) domain.

[0224] The above-mentioned indication method can either add an indication field to the first DCI or use the existing indication field in the first DCI.

[0225] For example, the first indication information is indicated by a newly added field in the first DCI; specifically, such as Figure 3 As shown, the first indication information can be a Physical Uplink Control Channel (PUCCH) resource identifier or a Configured Grant (CG) configuration identifier, or a bitmap, that is, the network side configures 4 uplink resources. If the bitmap is 1000, it indicates the first resource among the 4 uplink resources indicated.

[0226] For example, the first indication information is indicated by a domain already present in the first DCI;

[0227] Specifically, it can be at least one of the PUCCH resource indicator field and the PDSCH-to-HARQ_feedback timing indicator field in DCI format 1_0 / 1_1 / 1_2;

[0228] Furthermore, at least one of the Time Domain Resource Assignment (TDRA) field and Modulation and Coding Scheme (MCS) field in DCI format 1_0 / 1_1 / 1_2 is redefined as second indication information. This second indication information is used to determine the first information corresponding to the first DCI. The terminal determines the content carried on the third uplink resource based on the first information. The second indication information includes at least one of the following:

[0229] The event identifier that triggers the reporting; that is, the reporting content corresponding to the event is carried on the third uplink resource;

[0230] Report configuration identifier; that is, the reporting content corresponding to the report configuration is carried on the third uplink resource;

[0231] The first uplink resource identifier, such as Figure 4 As shown, the third uplink resource carries the report content corresponding to the first information reported on the first uplink resource;

[0232] The time slot offset between the first uplink resource and the first DCI, such as Figure 4 As shown; that is, the third uplink resource carries the report content corresponding to the first information reported on the first uplink resource.

[0233] Optionally, the first uplink resource and the first DCI are on the same CC or bandwidth part (BWP), or their subcarrier space (SCS) is the same.

[0234] Optionally, when the first uplink resource and the BWP where the first DCI is located correspond to different SCSs, the terminal determines the first uplink resource based on the minimum value of the SCS.

[0235] Optionally, the first DCI may further include second indication information, which is used to indicate the first information corresponding to the first DCI.

[0236] Optionally, the second indication information includes at least one of the following:

[0237] The event identifier that triggers the beam report;

[0238] Beam report configuration identifier;

[0239] First uplink resource identifier;

[0240] The time slot offset between the first uplink resource and the first DCI.

[0241] Optionally, the first indication information is indicated via the CSI request field in DCI format 0_1.

[0242] In an optional embodiment, the fourth uplink resource is associated with the first report configuration, and the terminal determines the target first report configuration based on the CSIrequest domain, thereby determining that the fourth uplink resource associated with the first target report configuration is the third uplink resource.

[0243] Optionally, the report configuration corresponding to the trigger state of the CSI request field can only be either the first target report configuration or the second target report configuration; the first target report configuration is a report configuration used for terminal-triggered beam reporting or beam management; the second target report configuration is a periodic, semi-persistent, or non-periodic CSI report configuration.

[0244] In this embodiment of the application, at least one of the TDRA field or MCS field in DCI format 1_0 / 1_1 / 1_2 can be redefined as third indication information. This third indication information is used to determine the third uplink resource, such as... Figure 3 As shown; the third indication information is at least one of the following:

[0245] a) PUCCH resource identifier or CG configuration identifier; wherein, the PUCCH resource identifier and the PUCCH resource indicator used to carry HARQ-ACK are different fields;

[0246] b) CSI request.

[0247] Optionally, when the fourth or third uplink resource is a PUCCH resource, the PUCCH resource must be at least one of PUCCH format 2 / 3 / 4.

[0248] Optionally, the third uplink resource is at least one of PUCCH resource and Physical Uplink Shared Channel (PUSCH) resource.

[0249] For example, the first mode (or mode A) in the embodiments of this application may be:

[0250] The terminal sends first information on the first uplink resource;

[0251] The terminal detects the first DCI, and the first DCI indicates or schedules the third uplink resource;

[0252] The terminal sends a first report on the third uplink resource;

[0253] For example, the first mode (or mode A) in the embodiments of this application may be:

[0254] The terminal sends first information on the first uplink resource;

[0255] The terminal sends a first report on the second uplink resource.

[0256] Optionally, the method further includes:

[0257] The terminal receives first configuration information sent by the network-side device. The first configuration information includes configuration information for multiple first uplink messages. The first uplink message is used to send the first information, and at least some of the configuration information of different first uplink messages is different.

[0258] In this embodiment of the application, the network device may pre-configure multiple first uplink messages (e.g., uplink control information UCI) as candidate messages carrying first information. The configurations of different first uplink messages are at least partially different, which may be due to different configuration items or different values ​​of the configuration items.

[0259] Optionally, the payload size or payload size range of the first report corresponding to different first uplink messages may be different; the method further includes:

[0260] When the first event is satisfied, the terminal determines the target uplink message based on the payload size of the first report corresponding to the first event, wherein the target uplink message is at least one of the plurality of first uplink messages;

[0261] The terminal sends the first information according to the configuration information corresponding to the target uplink information.

[0262] Different first uplink messages correspond to different payload sizes or payload ranges for the first report. Based on this attribute, after determining the payload size of the first report, the terminal can select the matching first uplink message to carry the first message. After receiving the first uplink message, the network-side device can anticipate the payload size of the first report, thereby improving the rationality of resource scheduling.

[0263] For example, in this embodiment of the application, the terminal receives first configuration information from the network side. The configuration of the first configuration information can be configured simultaneously with the first higher-layer parameters (RRC configuration) configured by the network-side device, or they can be configured separately. The first configuration information includes configuration information related to multiple first UCIs, and the multiple first UCIs correspond to different payload sizes or payload size ranges; the first UCI configuration information includes at least one of the following:

[0264] Configure identifiers;

[0265] UCI sequence;

[0266] UCI type;

[0267] Target uplink resources;

[0268] The configuration information of the multiple first UCIs is different, that is, at least one target information is different, and the target information is at least one of the configuration information of the first UCIs.

[0269] When the conditions of the first event are met, the terminal determines the target first UCI from the plurality of first UCIs according to the payload size of the first report, and sends the target first UCI according to the configuration information of the target first UCI;

[0270] The first event is defined by network configuration or protocol and is used to determine whether the terminal triggers the reporting of the first report.

[0271] In another example, in this embodiment of the application, the network-side device configures multiple scheduling request configurations (SR configurations) (i.e., the first configuration information). Each SR configuration includes an SR config ID, a PUCCH resource identifier, sequence-related configuration information, etc. Different SRs correspond to different payload sizes or payload size ranges. See the table below for details. Assume the network is configured with 8 SR configurations.

[0272]

[0273] Once the network determines that the conditions for the first event are met and the payload size of the corresponding first report content is determined, it can select the corresponding SR configuration according to the table above and send the corresponding SR based on the configuration information. For example, when the payload size is between X6 and X7, the corresponding SR sequence (first uplink message) is sent on the corresponding PUCCH resource based on SR configuration #6.

[0274] By configuring multiple SR configurations, with different SRs corresponding to different report payload sizes, the network can be informed of the report size by sending different SRs, which facilitates network resource allocation and scheduling.

[0275] Optionally, when the uplink resources corresponding to the target uplink message and the uplink resources corresponding to the second uplink message at least partially overlap, the method further includes:

[0276] The terminal performs a first operation, which includes at least one of the following:

[0277] If the priority of the target uplink message is higher than the priority of the second uplink message, the target uplink message is sent on the uplink resource corresponding to the target uplink message;

[0278] If the priority of the target uplink message is lower than the priority of the second uplink message, the second uplink message is sent on the uplink resource corresponding to the second uplink message;

[0279] If the second uplink message includes a scheduling request triggered by beam failure recovery, the second uplink message is sent on the uplink resource corresponding to the second uplink message;

[0280] If the second uplink message does not include a scheduling request triggered by beam failure recovery, the target uplink message is sent on the uplink resource corresponding to the target uplink message.

[0281] The identified target uplink message may conflict with other uplink messages (partial overlap of transmission resources). In this embodiment, a conflict resolution solution is provided to ensure the stability of data transmission.

[0282] For example, when the target uplink resource corresponding to the first UCI overlaps with the uplink resource corresponding to the second UCI, the terminal performs a first operation; the first operation includes any one of the following:

[0283] 1) Only the target uplink resource corresponding to the target first UCI is valid, and the terminal sends the first UCI on the target uplink resource corresponding to the target first UCI; the conditions corresponding to this method include at least one of the following:

[0284] The first UCI has a higher priority than the second UCI;

[0285] The second UCI includes SRs other than beam failure recovery triggered SRs, or in other words, the second uplink message does not include a beam failure recovery triggered scheduling request;

[0286] 2) Only the uplink resource corresponding to the second UCI is valid, and the terminal transmits the second UCI on the target uplink resource corresponding to the second UCI; the conditions corresponding to this method include at least one of the following:

[0287] The first UCI has a lower priority than the second UCI;

[0288] The second UCI is a beam failure recovery triggered SR;

[0289] The beam failure recovery includes at least one of SCell beam failure recovery and beam failure recovery triggered by at least one BFD-RS set beam failure.

[0290] Optionally, the method further includes:

[0292] The fourth piece of information includes at least one of the following:

[0293] The second higher-layer parameters configured for network-side devices;

[0294] The second parameter determined by the terminal.

[0295] The beam measurement and reporting in this application embodiment can be performed on the reference signal RS (i.e. target RS type) of the target type. The target RS type can be determined based on the fourth information, that is, the target RS type can be determined by at least one of the second parameters determined by the higher-layer parameters configured by the network-side device and the terminal's own relevant information.

[0296] Optionally, the second high-level parameter includes at least one of the following:

[0297] The content of the beamforming report;

[0298] A third high-level parameter, which indicates the method for determining the target RS type;

[0299] A fourth high-level parameter, which indicates the target RS type;

[0300] The fifth high-level parameter is used to determine the configuration information of the candidate RS.

[0301] In this embodiment, the terminal can determine the corresponding target RS type based on the beam report content in the higher-layer parameters configured on the network side, or it can determine the target RS type based on the method of determining the target RS type indicated by the higher-layer parameters, or the higher-layer parameters can directly indicate the target RS type. Determining the target RS type using the configuration information of candidate RSs can be based on determining the RS type of the current beam based on the RS type of the candidate beam.

[0302] Optionally, if the second higher-layer parameters include a third higher-layer parameter, the terminal determines the target RS type corresponding to the beam report based on the third higher-layer parameter, including at least one of the following:

[0303] The target RS type is determined based on the quasi-co-located QCL resource RS in the second TCI state;

[0304] The target RS type is determined based on the quasi-co-located QCL root resource RS of the second TCI state.

[0305] Optionally, the terminal determines the second TCI state based on a sixth higher-layer parameter, wherein the second TCI state includes at least one of the following:

[0306] The TCI status indicated by the network-side device;

[0307] The first control resource set CORESET corresponds to the TCI state, where the first CORESET is a CORESET that does not follow the TCI state indicated by the network.

[0308] Taking RS types including a first RS type and a second RS type as an example, the terminal determines the target RS type based on at least one of the following methods, and performs measurement and reporting based on the target RS:

[0309] (1) Determined by high-level parameters; wherein, the high-level configuration parameters include at least one of the following:

[0311] 2) Third higher-layer parameters, which indicate the method for determining the target RS type; the definition of the current beam (i.e., the corresponding channel type) and the RS type corresponding to the current beam can be determined based on the higher-layer configuration parameters. Specifically, the determination method includes at least one of the following:

[0315] The TCI state indicated by the network-side device;

[0316] The first CORESET corresponds to the TCI state, and the first CORESET is a CORESET that does not follow the indicated TCI state;

[0317] In this embodiment of the application, the second TCI state can be determined by a sixth high-level parameter; the target RS type can be determined by two levels of high-level parameters. The first level parameter is to determine the target TCI state, that is, to select one or both of the RS type determined from the TCI state of the first CORESET and the indicated TCI state; the second level parameter is to determine the target RS type based on the QCL source RS and / or QCL root source RS of the TCI state.

[0318] Optionally, both the third high-level parameter and the sixth high-level parameter are newly added high-level parameters.

[0319] Optionally, the third higher-layer parameter is associated with the beam reporting configuration; and / or, the sixth higher-layer parameter is associated with the beam reporting configuration.

[0320] A third high-level parameter is used to indicate the target RS type. Specifically, when the third high-level parameter is configured as a first RS, the target RS is a first RS; when the third high-level parameter is configured as a second RS, the target RS is a second RS.

[0321] Furthermore, the third high-level parameter is a newly added high-level parameter;

[0322] Furthermore, the third high-level parameter is associated with the report configuration;

[0323] 3) RS configuration information: When the RS is used for candidate beam measurement and selection; specifically, when all the RSs are of the first RS type, the terminal determines the target RS type as the first RS type; when all the RSs are of the second RS type, the terminal determines the target RS type as the second RS type.

[0324] (2) Terminal itself determines

[0325] The terminal can determine the target RS type based on its own capabilities, status, and other information.

[0326] Optionally, if the fourth information includes the second parameter determined by the terminal, the beam report may also include target RS type indication information.

[0330] The beam report includes an index of a first RS, which is an RS selected by the terminal for reporting. The first RS is of the same type as the target RS. The index of the first RS is determined according to the order of the first RS in the RS set relative to all RSs, or according to the order of the first RS in the RS set relative to RSs of the same type as the first RS, or according to the index of the first RS itself.

[0331] Optionally, the beam report includes RS groups, where RS types are the same within the same RS group, and / or RS types are different within different RS groups.

[0332] When the target RS type is determined by higher-layer parameters, the terminal reports according to at least one of the following methods:

[0333] 1) The terminal determines the index of the first RS based on the total number and order of RSs in the RS set to which the first RS is located and reports it; the first RS is an RS of the same type as the target RS that is selected for reporting, and the RS set includes at least one of the first RS type and the second RS type;

[0334] For example, if the RS set includes {CSI-RS#1, SSB#2, SSB#6, CSI-RS#3, CSI-RS#9, SSB#8}, and the network is configured with CSI-RS as the target RS type and CSI-RS#9 meets the conditions, then the RS index reported in the report will be 4.

[0335] 2) The terminal determines and reports the index of the first RS based on the number and order of RSs of the same RS type as the first RS in the RS set where the first RS is located; the first RS is the RS selected for reporting that is of the same type as the target RS, and the RS set includes at least one of the first RS type and the second RS type;

[0336] For example, if the RS set includes {CSI-RS#1, SSB#2, SSB#6, CSI-RS#3, CSI-RS#9, SSB#8}, and the network is configured with CSI-RS as the target RS type and CSI-RS#9 meets the conditions, then the RS index reported in the report will be 2.

[0337] When the target RS type is determined by the terminal itself, the terminal reports according to at least one of the following methods:

[0338] 1) The first information indicates at least one of the target RS type and the payload size of the report determined based on the target RS type;

[0339] 2) Add indication information to each reported RS in the first report to indicate the type of the reported RS;

[0340] For example, if the RS set includes {CSI-RS#1, SSB#2, SSB#6, CSI-RS#3, CSI-RS#9, SSB#8}, and SSB#6 and CSI-RS#9 meet the conditions, then the report will indicate SSB#6 with (0, 6) or (0, 1), and CSI-RS#9 with (1, 9) or (1, 2); where 0 indicates that the corresponding RS type is SSB, and 1 indicates that the corresponding RS type is CSI-RS; 6 represents the SSB index, and 1 indicates which SSB in the RS set SSB#6 belongs to; similarly, 9 represents the CSI-RS index, and 2 indicates which CSI-RS in the RS set CSI-RS#9 belongs to;

[0341] 3) Report N groups of RS in the report. RS within the same group have the same type, while RS in different groups have different types. Add indication information to each group of RS to indicate the type of RS.

[0342] Furthermore, the number of RSs in each group of RSs is determined by the RRC configuration, or indicated by the terminal in the first report;

[0343] Specifically, the RS set includes {CSI-RS#1, SSB#2, SSB#6, CSI-RS#3, CSI-RS#9, SSB#8}. If SSB#6, SSB#8, CSI-RS#1, and CSI-RS#9 meet the conditions, then the report will indicate SSB#6 and SSB#8 with (0, 6, 8) or (0, 1, 2), and CSI-RS#1 and CSI-RS#9 with (1, 1, 9) or (1, 0, 2). Here, 0 indicates that the RS type corresponding to the RS group is SSB, and 1 indicates that the RS type corresponding to the RS group is CSI-RS. 6 and 8 represent SSB indexes, and 1 and 2 indicate which SSB in the RS set SSB#6 and SSB#8 belong to. Similarly, 1 and 9 represent CSI-RS indexes, and 0 and 2 indicate which CSI-RS in the RS set CSI-RS#1 and CSI-RS#9 belong to.

[0344] 4) Report N groups of RS according to preset rules, wherein RS within the same group are of the same type, and RS in different groups are of different types;

[0345] Furthermore, the number of RSs in each group of RSs is determined by the RRC configuration, or indicated by the terminal in the first report;

[0346] For example, if the RS set includes {CSI-RS#1, SSB#2, SSB#6, CSI-RS#3, CSI-RS#9, SSB#8}, and SSB#6, SSB#8, CSI-RS#1, and CSI-RS#9 meet the conditions, the terminal will report the SSB first, and then report the CSI-RS according to the preset rules. That is, the UCI sequence is (6, 8, 1, 9) or (1, 2, 0, 2) indicating SSB#6, SSB#8, CSI-RS#1, and CSI-RS#9. Here, 6 and 8 represent the SSB index, and 1 and 2 respectively indicate which SSB in the RS set SSB#6 and SSB#8 belong to. Similarly, 1 and 9 represent the CSI-RS index, and 0 and 2 respectively indicate which CSI-RS in the RS set CSI-RS#1 and CSI-RS#9 belong to.

[0347] 5) The terminal determines the index of the first RS based on the total number and order of RSs in the RS set to which the first RS is located and reports it; the first RS is the RS selected for reporting, and the RS set includes at least one of the first RS type and the second RS type;

[0348] For example, if the RS set includes {CSI-RS#1, SSB#2, SSB#6, CSI-RS#3, CSI-RS#9, SSB#8}, and CSI-RS#9 meets the condition, then the RS index reported in the report is 4.

[0349] 6) The terminal determines and reports the index of the first RS based on the number and order of RSs of the same RS type as the first RS in the RS set where the first RS is located; the first RS is the RS selected for reporting, the first RS is any one of the first RS type and the second RS type, and the RS set includes at least one of the first RS type and the second RS type;

[0350] For example, if the RS set includes {CSI-RS#1, SSB#2, SSB#6, CSI-RS#3, CSI-RS#9, SSB#8}, and the terminal determines that CSI-RS is the target RS type and CSI-RS#9 meets the conditions, then the RS index reported in the report is 2.

[0351] In this embodiment of the application, when the mixed configuration of SSB and CSI-RS or the measurement RS cannot be determined as CSI-RS or SSB based on the indicated TCI state, it is proposed to determine the RS type of measurement and reporting through higher-layer signaling (e.g., RRC configuration) and the UE itself; wherein when mixed reporting or the UE itself determines it, the RS type indication information is introduced in the uplink message (e.g., UCI).

[0352] Optionally, the target RS type includes at least one of a first RS type and a second RS type, and the method further includes:

[0353] If the eighth condition is met, at least one of the second RS and the third RS shall be reported; the eighth condition includes at least one of the following:

[0354] The difference between the measurement result of the second RS and the measurement result of the third RS is greater than or equal to the first threshold value;

[0355] The measurement result of the third RS is less than or equal to the second threshold value;

[0356] Wherein, the second RS and the third RS are both of the first RS type, the second RS is the RS corresponding to the candidate beam, and the third RS is the RS corresponding to the currently used beam;

[0357] And / or, if the ninth condition is met, report at least one of the fourth RS and the fifth RS; the ninth condition includes at least one of the following:

[0358] The difference between the measurement result of the fourth RS and the measurement result of the fifth RS is greater than or equal to the third threshold value;

[0359] The measurement result of the fifth RS is less than or equal to the fourth threshold value;

[0360] The fourth RS and the fifth RS are both of the second RS type. The fourth RS is the RS corresponding to the candidate beam, and the fifth RS is the RS corresponding to the currently used beam.

[0361] In this embodiment of the application, it can be understood that different types of RS perform reporting based on different judgment conditions, thereby improving the reliability of beam management.

[0362] For example, when the target RS type includes a first RS type and a second RS type, the terminal needs to select at least one of the second RS and the third RS whose measurement results meet the first condition for reporting during the process of selecting the RS to report, and / or at least one of the fourth RS and the fifth RS whose measurement results meet the second condition for reporting.

[0363] The second RS and the third RS are RS of the same type as the first RS, where the second RS is the RS corresponding to the candidate beam and the third RS is the RS corresponding to the currently used beam; the fourth RS and the fifth RS are RS of the same type as the second RS, where the fourth RS is the RS corresponding to the candidate beam and the fifth RS is the RS corresponding to the currently used beam.

[0364] The reporting conditions for the second and third RSs include at least one of the following:

[0365] The measurement results of the second RS are better than the measurement results of the third RS than the first threshold value;

[0366] The measurement result of the third RS is lower than the second threshold value;

[0367] The reporting conditions for the fourth and fifth RS include at least one of the following:

[0368] The measurement results of the fourth RS are better than those of the fifth RS than the third threshold value;

[0369] The measurement result of the fifth RS is lower than the fourth threshold;

[0370] The first threshold value is different from the third threshold value, and both need to be configured in the report configuration or event configuration information; the second threshold value is different from the fourth threshold value, and both need to be configured in the report configuration or event configuration information.

[0371] Optionally, if the RS corresponding to the currently used beam is the same as the sixth RS, the method further includes:

[0372] The sixth RS is not measured;

[0373] Alternatively, measure the sixth RS without comparing the measurement result of the sixth RS with the measurement result of the RS corresponding to the currently used beam.

[0374] Wherein, the sixth RS is the RS corresponding to the candidate beam.

[0375] In this embodiment of the application, if the current beam is included in the new beamlist, the UE does not measure the current beam, or measures it but does not compare it.

[0376] Optionally, the first RS type is SSB, and the second RS type is CSI-RS;

[0377] The method described above for determining the target RS type is applicable to the RS determination of at least one of the current beam and the candidate beam.

[0378] Optionally, if the target mode includes the first mode, the method further includes at least one of the following:

[0379] After the terminal sends the first information on the first uplink resource, it sends the first information on the fifth uplink resource if the second condition is met; wherein the second condition includes at least one of the following: the terminal does not detect the first DCI within a second preset time period after the first uplink resource; the condition corresponding to the first event is still met; the payload size corresponding to the first report has not changed;

[0380] After the terminal sends the first information on the first uplink resource, before the first time interval, if the conditions corresponding to the second event are met, the terminal does not send the second information on the sixth uplink resource; wherein, the second event is an event that triggers the second report, the sixth uplink resource is an uplink resource associated with the second event or the second report configuration, the second information is related to the second report, the second report is a beam report that meets the conditions corresponding to the second event, and the second report configuration is higher-layer configuration information associated with the second report; the first time interval includes at least one of the following: a second preset duration after the first uplink resource, the last symbol of the physical downlink control channel (PDCCH) carrying the first DCI.

[0381] In this embodiment of the application, for the first mode, after sending the first information, the first information can be retransmitted if the second condition is met.

[0382] In this embodiment of the application, for the first mode, after sending the first information, even if other event conditions are met within a certain period of time and the second information needs to be reported, the terminal will avoid reporting the second information in order to avoid communication chaos.

[0383] If the second condition is met after the first information is sent, the terminal will send the first information again on the fifth uplink resource.

[0384] The second condition includes at least one of the following:

[0385] If the terminal does not detect the first DCI within X time periods after the first uplink resource;

[0386] The conditions corresponding to the first event are still met;

[0387] The payload size corresponding to the first report did not change;

[0388] The fifth uplink resource is the most recent uplink resource after the first uplink resource by time X. The fifth uplink resource is configured by the network side. Optionally, the network side may configure uplink resources dedicated to carrying the first information.

[0389] The unit of time X can be symbol / slot / subframe / ms / s, etc., and the value of X is determined by network configuration or protocol agreement; further optionally, when the SCS of the first uplink resource and the first DCI are different, the value of time X is determined based on the minimum value of their SCS.

[0390] After sending the first information, if the terminal detects the first DCI within X time after the first uplink resource, it shall report the first report on the third uplink resource indicated or scheduled in the first DCI.

[0391] The unit of time X is symbol / slot / subframe / ms / s, etc., and the value of X is determined by network configuration or protocol agreement; further optionally, when the SCS of the first uplink resource and the first DCI are different, the value of time X is determined based on the minimum value of their SCS.

[0392] Before the first time period, if the condition corresponding to the second event is met, the terminal will not report the second information on the sixth uplink resource; the sixth uplink resource is a reporting resource configured by the network and associated with the second event, the second event is configured by RRC and may be the same as or different from the first event; the first time period is any one of the following:

[0393] a) Time X after the first uplink resource;

[0394] b) The last symbol of the PDCCH carrying the first DCI can be understood as allowing the reporting of the second information when the conditions corresponding to the second event are met after the first DCI has been sent.

[0395] Optionally, the fifth uplink resource is the uplink resource among the first uplink resources that is closest to the time point of the second preset duration after the first uplink sub-resource, wherein the first uplink sub-resource is the resource among the first uplink resources that carries the first information.

[0396] In this embodiment, when the first uplink resource is a periodic resource configured by the network side to carry the first information, there are multiple resource occasions for the first uplink resource. When an event is met, the UE will send the first information on the most recent resource occasion of the first uplink resource. At this time, the fifth uplink resource should be understood as the most recent uplink resource after a second preset time period following the resource occasion of the first uplink resource carrying the first information (for example, it could be the resource occasion of the first uplink resource).

[0397] Optionally, the method further includes at least one of the following:

[0398] Within a third preset time period after the terminal sends the first report on the third uplink resource, if a second DCI is detected, the terminal retransmits the first report according to the uplink resource indicated by the second DCI.

[0399] If the terminal does not detect the second DCI within a third preset time period after sending the first report on the third uplink resource, and if the third condition is met within a fourth preset time period after the third preset time period, the terminal will not report the first information.

[0400] The third condition includes at least one of the following:

[0401] The conditions corresponding to the first event are met;

[0402] The reference signal RS corresponding to the currently used beam is the same as the RS corresponding to the currently used beam reported in the first report;

[0403] The difference between the measurement result of the RS corresponding to the currently used beam and the measurement result of the RS corresponding to the current beam reported in the first report is within a first preset range;

[0404] The terminal determines that the RS corresponding to the candidate beam reported is the same as the RS corresponding to the candidate beam reported in the first report;

[0405] The difference between the measurement result of the RS corresponding to the candidate beam reported by the terminal and the measurement result of the RS corresponding to the candidate beam reported by the first report is within a second preset range.

[0406] In this embodiment, the first report can be retransmitted upon receiving a retransmission resource indication after sending the first report. If the terminal detects a second DCI within a Y-time period after reporting the first report on the third uplink resource, the terminal retransmits the first report on the uplink resource indicated by the second DCI or scheduled; otherwise, the terminal considers the first report to have been successfully received by the network side.

[0407] For example, such as Figure 5 and Figure 6 As shown, after the transmission of the first report is completed, the terminal opens a detection window (window length Y). If the second DCI is detected within the detection window, the retransmitted first report and the corresponding uplink resource are determined according to the indication information in the second DCI. Specifically, the first report to be retransmitted is determined according to the slot offset indicated in the second DCI, and the PUCCH resource corresponding to the retransmission is determined according to the K1 value indicated in the second DCI. When the uplink resource carrying the first report is PUSCH, the difference from PUCCH is that the PUSCH resource corresponding to the retransmission is determined according to K2 indicated in the second DCI.

[0408] The unit of time Y is symbol / slot / subframe / ms / s, etc., and the value of Y is determined by network configuration or protocol agreement; further optionally, when the SCS of the third uplink resource and the second DCI are different, the value of time Y is determined based on the minimum value of the SCS of the two.

[0409] In this embodiment of the application, if no retransmission resource indication is received after sending the first report, the first information will not be reported again according to the third condition. The third condition can be understood as follows: if the first event is met, but the beam to be reported is not much different from the beam previously reported, the first information will not be reported again, thereby avoiding invalid reporting, improving resource utilization and reducing terminal power consumption. This can be understood as the mechanism to avoid repeated reporting in the first mode.

[0410] If the terminal does not detect the second DCI within a time period Y after reporting the first report on the third uplink resource, and if the third condition is met within a time period T after time Y, the terminal will not report the first information.

[0411] The third condition includes at least one of the following:

[0412] i. The condition corresponding to the first event is met;

[0413] ii. The first RS and the second RS are the same as the first RS and the second RS corresponding to the first report;

[0414] iii. The difference between the measurement result of the first RS and the measurement result of the first RS reported in the first report is less than the first threshold;

[0415] iv. The difference between the measurement result of the second RS and the measurement result of the second RS reported in the first report is less than the second threshold;

[0416] Wherein, the first RS is the RS corresponding to the beam currently being used by the terminal, and the second RS is the RS corresponding to the candidate beam determined and reported by the terminal; wherein the RS corresponding to the beam currently being used by the terminal is the QCL source RS of the indicated TCI state, and the RS corresponding to the candidate beam is configured by RRC. The first threshold and the second threshold are configured by RRC, and their values ​​can be the same or different.

[0417] The unit of time T is symbol / slot / subframe / ms / s, etc., and the value of T is determined by network configuration or protocol agreement; further optionally, the value of T can be infinite, that is, there is no time window.

[0418] Optionally, in this embodiment, whether the terminal does not report the first information based on the third condition needs to be enabled based on preset information. The preset information includes at least one of the following:

[0419] a) As stipulated in the agreement;

[0420] b) RRC configuration;

[0421] c) MAC CE or DCI indication; further optionally, the DCI may be a group common DCI.

[0422] Optionally, if the target mode includes a second mode, the method further includes:

[0423] After the terminal sends the first report on the second uplink resource, if the fourth condition is met, the terminal sends the first report again on the seventh uplink resource;

[0424] The fourth condition includes at least one of the following:

[0425] The terminal did not detect feedback information indicating successful reception of the first report within a fifth preset time period after the second uplink resource;

[0426] The conditions corresponding to the first event are met;

[0427] The load size corresponding to the first report did not change.

[0428] In this embodiment of the application, in the second mode, after sending the first report, the first report can be retransmitted based on the fourth condition, thereby improving the reliability of data transmission.

[0429] If the fourth condition is met after the first report is sent, the terminal will send the first report again on the seventh uplink resource.

[0430] The fourth condition includes at least one of the following:

[0431] i. If the terminal does not detect the information of successfully receiving the first report from the network side within X time after the second uplink resource; Optionally, the feedback information can be carried by any one of MAC CE, UE-specific DCI or groupcommon DCI;

[0432] ii. The conditions corresponding to the first event are still met;

[0433] iii. The payload size corresponding to the first report has not changed;

[0434] Optionally, the seventh uplink resource is the most recent uplink resource after X time after the second uplink resource. The seventh uplink resource is configured by the network side. Further, optionally, the network side can configure uplink resources dedicated to carrying the first report.

[0435] The unit of time X is symbol / slot / subframe / ms / s, etc., and the value of X is determined by network configuration or protocol agreement; further optionally, when the SCS corresponding to the second uplink resource and the channel carrying feedback information are different, the value of time X is determined based on the minimum value of the two SCS.

[0436] Optionally, the seventh uplink resource is the uplink resource among the second uplink resources that is closest to the time point of the fifth preset time after the second uplink sub-resource, and the second uplink sub-resource is the resource among the second uplink resources that carries the first report.

[0437] In this embodiment, for the second mode, the second uplink resource can be a periodic resource configured by the network side to carry the first report. The second uplink resource has multiple resource occasions. When an event is met, the UE will send the first report on the most recent resource occasion of the second uplink resource. Therefore, the seventh uplink resource should be understood as the most recent uplink resource after a fifth preset time period following the resource occasion of the second uplink resource carrying the first report (for example, it could be a resource occasion of the second uplink resource).

[0438] Optionally, the method further includes:

[0439] After the terminal sends the first report on the second uplink resource, the terminal detects feedback information that the first report has been successfully received within a fifth preset time period after the second uplink resource. If the fifth condition is met within a sixth preset time period after the fifth preset time period, the terminal does not report the first information.

[0440] The fifth condition includes at least one of the following:

[0445] The terminal determines that the difference between the measurement result of the RS corresponding to the candidate beam reported and the measurement result of the RS corresponding to the candidate beam reported in the first report is within the fourth preset range.

[0446] In this embodiment of the application, after sending the first report, if it is determined that the first report has been successfully received, the first information will not be reported again according to the fifth condition. The fifth condition can be understood as follows: if the first event is met, but the beam to be reported is not much different from the beam previously reported, the first information will not be reported again, thereby saving and avoiding invalid reporting. This can be understood as the mechanism to avoid repeated reporting in the second mode.

[0447] After sending the first report, if the terminal successfully detects the information of successful reception of the first report from the network side within X time after the second uplink resource, and if the fifth condition is met within T time after X time, the terminal will not report the first information.

[0448] The fifth condition includes at least one of the following:

[0449] The condition corresponding to the first event is met;

[0450] The first RS and the second RS are the same as the first RS and the second RS corresponding to the first report;

[0451] The difference between the measurement result of the first RS and the measurement result of the first RS reported in the first report is less than the first threshold.

[0452] The difference between the measurement result of the second RS and the measurement result of the second RS reported in the first report is less than the second threshold;

The first threshold and the second threshold are configured by RRC, and their values ​​can be the same or different.

[0454] The unit of time T is symbol / slot / subframe / ms / s, etc., and the value of T is determined by network configuration or protocol agreement; further optionally, the value of T can be infinite, that is, there is no time window.

[0455] Optionally, in this embodiment, whether the terminal does not report the first information based on the fifth condition needs to be enabled based on preset information. The preset information includes at least one of the following:
