[0051] For ease of understanding, the following describes some aspects of the embodiments of this application:
[0052] For CSI measurements, the higher layer configures report settings and resource settings for the terminal, as well as one or two trigger state lists. CSI resources are used for CSI measurements. A CSI resource setting can include configuration information for RS (Reference Signal) resources used for channel measurements, reference signals (RS) used for interference measurements, and / or CSI-interference measurement (CSI-IM) resources. Zhang Hongduan performs CSI calculations based on these RS and / or CSI-IM resources. The terminal then reports according to the report settings, such as periodic CSI reporting, semi-persistent CSI reporting, and aperiodic CSI reporting.
[0053] Currently, when non-periodic CSI reporting is triggered, if it is transmitted along with business data, the latency of business data transmission will be limited by the CSI processing time, resulting in increased data transmission latency (usually the CSI processing time is longer than the data preparation time), which in turn leads to a decrease in the latency performance of business data transmission.
[0054] On the other hand, CSI reporting is transmitted on pre-configured resources. Therefore, in the event of a conflict or collision, resources need to be adjusted to ensure proper information transmission. This may result in the resources required for CSI reporting not matching the resources actually used for transmission, leading to poor CSI report transmission performance. Furthermore, the number of information bits transmitted on PUCCH resources is relatively small. When multiple UCIs are transmitted together, different UCI types require different encoding methods, which may increase processing complexity. Therefore, the information transmission method proposed in this application is presented.
[0055] The information transmission method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.
[0056] Reference Figure 2 This application provides an information transmission method, such as... Figure 2 As shown, the information transmission method includes:
[0057] Step 201: The terminal triggers one or more CSI measurements based on first information or a preset event, where the first information is indication information sent by the network-side device;
[0058] Step 202: The terminal sends at least one CSI report of the CSI measurement according to the second information and / or the first rule;
[0059] The second information is used to indicate at least one of the following: whether to transmit a CSI report; the information corresponding to the CSI report; whether to transmit uplink service data;
[0060] The first rule includes: sending the CSI report via the first uplink resource after the first moment.
[0061] In this embodiment, a first message can trigger one or more CSI measurements. For example, the first message can be used to trigger periodic measurements, or the network-side device can trigger multiple CSI measurements by sending multiple first messages. A preset event can trigger one or more CSI measurements. For example, a CSI measurement can be triggered when a certain preset event is met. A new CSI measurement can be triggered when the preset event is met again, wherein the triggering events for the two CSI measurements can be the same or different. It should be understood that triggering a CSI measurement with the first message requires the fulfillment of corresponding conditions, such as the signal quality of the serving cell being lower than a preset threshold.
[0062] Optionally, the aforementioned preset events may be trigger events configured by the network-side devices or trigger events agreed upon by the protocol, without further limitations.
[0063] Optionally, at least one CSI report from the aforementioned CSI measurements can be understood as a CSI report corresponding to at least a portion of the CSI measurements. Specifically, when the second information indicates the transmission of CSI reports, the terminal can transmit at least one CSI report from the CSI measurements. In this case, the CSI reports can be transmitted together with uplink service data, meaning the transmission of uplink service data is not affected by the second information indication. When the second information indicates information corresponding to the CSI reports, this information can be used to determine which CSI reports to report, and the terminal can send at least one CSI report based on the indicated information. When the second information indicates the transmission of uplink service data, the terminal can multiplex the CSI reports and uplink service data together for transmission. When the second information indicates no transmission of uplink service data, the terminal can send only at least one CSI report. Thus, by controlling the transmission of CSI reports according to the second information, appropriate resources can be selected for transmitting CSI reports, improving the performance of CSI report transmission.
[0064] Optionally, the aforementioned first rule can be determined by the network-side device or by a protocol. The terminal sends at least one CSI report according to the first rule, thus clarifying the determination of CSI reporting resources and simplifying the process of determining CSI reporting resources.
[0065] Optionally, the information included in the aforementioned CSI report may include, but is not limited to, at least one of the following: channel measurements, interference measurements, cross-link interference (CLI) measurements, beam management reports, beam measurements, Layer 1 (L1) signal-to-noise and interference-plus-noise ratio (SINR) measurements, L1 reference signal received power (L1-RSRP) measurements, L3 measurements, CSI, precoding matrix indicator (PMI), location, Doppler frequency offset, timing advance (TA), channel quality indicator (CQI), precoding matrix indicator (PMI), channel state information reference signal resource indicator (CSI-RS Resource Indicator (CRI), and synchronization signal and PBCH block resource indicator. Indicator (SSBRI), Layer Indication (LI), and Rank Indication (RI).
[0066] Optionally, the CSI report transmission may be triggered along with other specific messages. For example, in some embodiments, the specific message may include, but is not limited to, any of the following:
[0067] Buffer Status Report (BSR);
[0068] Delay Status Report;
[0069] Hybrid automatic repeat request acknowledgement (HARQ-ACK).
[0070] Optionally, CSI measurements include at least one of channel measurements and interference measurements. Interference measurements include intra-cell interference measurements, inter-cell interference measurements, and CLI measurements; CLI measurements include at least one of CLI Received Signal Strength Indication (CLI-RSSI) and Sounding Reference Signal RSRP (SRS-RSRP).
[0071] This application embodiment triggers one or more CSI measurements via a terminal based on first information or a preset event. The first information is an indication sent by a network-side device. The terminal sends at least one CSI report of the CSI measurement according to second information and / or a first rule. The second information indicates at least one of the following: whether to transmit the CSI report; information corresponding to the CSI report; whether to transmit uplink service data. The first rule includes: transmitting the CSI report using a first uplink resource after a first time interval. This control over the transmission of CSI reports improves the performance of CSI report transmission.

That is, the first moment is separated from the first time position by a first time offset. For example, the first moment is the moment obtained by adding the CSI processing time to the time domain position where the first information is received.
[0101] Optionally, the completion of the CSI report can be understood as completing the CSI measurement, processing the CSI calculation, and preparing the content of the CSI report. At this time, since there are no available uplink resources, the CSI report is stored.

[0137] Optionally, in some embodiments, the first uplink resource satisfies at least one of the following:
[0138] The first uplink resource is the most recently available uplink resource after the CSI measurement;
[0139] The first uplink resource is the most recently available uplink resource after the first moment.
[0140] In this embodiment, the aforementioned available uplink resources can be understood as valid uplink resources, specifically referring to uplink resources that meet specific requirements, such as uplink resources that meet CSI processing time requirements or uplink resources that meet CSI report preparation time requirements. Uplink resources that meet CSI processing time requirements can be understood as those that can complete CSI processing before the start time of uplink resource transmission.
[0141] It should be noted that, in the embodiments of this application, the aforementioned first rule can be understood to include at least one of the following:
[0142] Send the CSI report on the nearest available uplink resource after the CSI measurement;
[0143] Send the CSI report on the nearest available uplink resource after the first moment.
[0144] Optionally, in some embodiments, the one or more CSI measurements include at least one of the following:

[0146] CSI measurements triggered by the preset event;
[0147] Periodic CSI measurements triggered by high-level configuration information;
[0148] The first information includes the dynamic signaling or the higher-level configuration information.
[0149] Optionally, the aforementioned dynamic signaling may include DL grant or UL grant. For example, a DL grant that schedules downlink data, but not a DL grant that schedules uplink data; a UL grant that schedules uplink data, but not a UL grant that schedules uplink data.
[0150] Optionally, in some embodiments, the first information is carried by at least one of the following: Terminal Dedicated Downlink Control Information (DCI), Group Common Control Information (DCI), Media Access Control Unit (MAC CE), and Radio Resource Control (RRC) Configuration Information.

[0152] In this embodiment of the application, the first uplink resource may include PUSCH resources or Physical Uplink Control Channel (PUCCH) resources.
[0153] For example, in some embodiments, CSI reports can be carried on PUSCH resources. Since PUSCH resources can carry more information bits, more information can be transmitted, thereby improving the reliability of CSI report transmission. Furthermore, CSI reports can use the same encoding method as business data, simplifying processing and reducing transmission complexity.

[0159] Reference Figure 3 This application also provides an information transmission method, such as... Figure 3 As shown, the information transmission method includes:
[0160] Step 301: The network-side device sends first information to the terminal, the first information being used to trigger CSI measurement;
[0161] Step 302: The network-side device receives at least one CSI report of the CSI measurement from the terminal, and the CSI report is reported based on a first rule and / or second information;
[0162] The second information is used to indicate at least one of the following: whether to transmit a CSI report; the information corresponding to the CSI report; whether to transmit uplink service data;

[0175] The information measured by the CSI;
[0176] The frequency domain unit information corresponding to the CSI report;
[0177] The spatial characteristics corresponding to the CSI report.
[0178] Optionally, the CSI report is carried on the first uplink resource via uplink control information (UCI), media access control (MAC) message, or radio resource control (RRC) message.
[0179] Optionally, the time interval between the time domain location of the first uplink resource and the first time point is less than or equal to a second preset duration.
[0180] Optionally, the time interval between the first moment and the time domain position at which the terminal receives the second information is less than or equal to a first preset duration.
[0181] Optionally, the first moment is determined based on a first time location, wherein the first time location includes any one of the following:
[0182] The time-domain location of receiving the first information;
[0183] The CSI measurement corresponds to the time-domain location of the reference signal;
[0184] The time-domain location is measured based on the reference signal measured by the CSI.

[0187] The temporal location of CSI reference resources;
[0188] The time domain location at which the CSI report was completed;
[0189] The CSI report is in the ready-to-go time domain.
[0190] Optionally, the first time point is determined based on a first time position and a first time offset, wherein the first time offset includes at least one of the following:
[0191] CSI processing time;
[0192] The CSI report preparation time;
[0193] Time offset indicated by network-side devices;
[0194] Uplink channel preparation time.
[0195] In this embodiment of the application, the performance of CSI report transmission is improved by restricting the transmission of CSI reports through second information and first rules, while at the same time simplifying the process of determining CSI reporting resources.
[0196] To better understand this application, some examples are provided below.
[0197] In some embodiments, the CSI report and the triggered CSI measurement satisfy the second rule, that is, the CSI measurement triggered by the terminal and the CSI report corresponding to the CSI measurement transmitted by the terminal must satisfy the second rule, thereby ensuring the validity of the CSI measurement and CSI report.
[0198] For example, the terminal triggers M CSI measurements based on first information or a preset event, and the terminal transmits N CSI reports based on second information or a first rule. These N CSI reports are some or all of the CSI reports corresponding to the M CSI measurements triggered above, and N and M are greater than or equal to 1.
[0199] The above-mentioned fulfillment of the second rule may include at least one of the following:
[0200] The time interval between the first moment and the time domain location of receiving the second information is less than or equal to the first preset duration T1;
[0201] The time interval between the first moment and the time domain location of the uplink resource transmitting the CSI report is less than or equal to the second preset duration T2; wherein, the time domain location of the uplink resource transmitting the CSI report is indicated by the second information or determined based on the first rule;
[0202] The time interval between the first moment and the time domain position of receiving the second information is greater than or equal to the third preset duration T3;
[0203] The time interval between the first moment and the time domain location of the uplink resource transmitting the CSI report is greater than or equal to the fourth preset duration T4;
[0204] Optionally, if the second rule above is satisfied, the terminal transmits N CSI reports based on the second information.
[0205] The definition of the first moment mentioned above is the same as that in the above embodiments, and will not be repeated here.
[0206] Optionally, T1 and T2 can be predefined or configured by the network-side device. T1 or T2 may include one or more of the following: CSI processing time, CSI measurement preparation time, CSI reporting preparation time, CSI reporting validity time, uplink resource preparation time, etc. T1 or T2 is used to ensure the timeliness and validity of CSI reports.
[0207] Optionally, T3 and T4 can be predefined or configured by the network-side device. T3 or T4 may include one or more of the following: CSI processing time, CSI measurement preparation time, CSI reporting preparation time, etc. T3 or T4 is used to ensure sufficient CSI measurement time and CSI processing time.
[0208] Optionally, when the second rule is not satisfied, the terminal's behavior includes at least one of the following:
[0209] When the time interval between the time domain location of receiving the second information and the first time is greater than or equal to T1, the terminal abandons the transmission of the CSI report, or reports placeholder information, or reports invalid CSI indication information.
[0210] When the time domain location of the uplink resource (i.e., the first uplink resource) transmitting the CSI report is greater than or equal to the time interval of the first moment, the terminal abandons the transmission of the CSI report, or reports placeholder information, or reports an indication of invalid CSI.
[0211] When the time interval between the receiving time domain location of the second information and the first time is less than T3, the terminal abandons the transmission of the CSI report, or reports placeholder information, or reports an indication of invalid CSI, or reports an indication of delaying the transmission of the CSI report.
[0212] When the time interval between the uplink resource for transmitting the CSI report and the first moment is less than T4, the terminal abandons the transmission of the CSI report, or reports placeholder information, or reports an indication of invalid CSI, or reports an indication of delaying the transmission of the CSI report.
[0213] Optionally, the terminal may abandon the transmission of CSI reports, or report placeholder information, or report indication information of invalid CSI, or report indication information of delaying the transmission of CSI reports, which may correspond to partial or complete CSI reports corresponding to M CSI measurements.
[0214] like Figure 4 As shown, assuming the first DCI-1 (i.e., the first information) triggers the transmission and CSI measurement of CSI-RS1, the first DCI-2 (i.e., the first information) triggers the transmission and CSI measurement of CSI-RS1, and the second DCI (i.e., the second information) is used to trigger the transmission of CSI reports, when the terminal sends a CSI report based on the second DCI, it only sends the CSI report 2 corresponding to the CSI measurement triggered by the first DCI-2. The CSI report 1 corresponding to the CSI measurement triggered by the first DCI-1 does not meet the time requirement corresponding to the second rule, that is, the time interval between the reception time of the first DCI-1 that triggers the measurement of CSI-RS1 and the time domain position of receiving the second DCI is greater than the first preset duration T1. Here, TX represents the time interval between the time domain position of receiving the first DCI-1 (i.e., the first information) and the time domain position of receiving the second DCI (i.e., the second information), and this TX is greater than T1.
[0215] Optionally, in some embodiments, the time domain position at which the terminal receives the second information is less than or equal to T1 compared to the time domain position at which the terminal receives the first information, and the terminal transmits one or more CSI reports based on the second information.
[0216] Optionally, the terminal does not expect the time domain location for receiving the second information to be greater than T1 compared to the time domain location for receiving the first information. That is, based on at least one CSI report of the CSI measurement transmitted by the terminal according to the second information, the network device will ensure that the time domain location for the terminal to receive the second information is greater than T1 compared to the time domain location for receiving the first information.
[0217] T1 is used to determine the validity period of CSI measurements and CSI reports triggered by the first information. That is, CSI measurements and CSI reports triggered by the first information are valid within the T1 time period. After the T1 time period, the validity of CSI measurements and CSI reports triggered by the first information is not guaranteed; that is, the information in the CSI reports may be outdated.
[0218] Optionally, the terminal does not expect the time interval between the first moment and the time domain location of the uplink resource transmitting the CSI report to be greater than T2.
[0219] Optionally, the terminal does not expect the time interval between the first moment and the time domain location of receiving the second information to be less than T3.
[0220] Optionally, the terminal does not expect the time interval between the first moment and the time domain location of the uplink resource transmitting the CSI report to be less than T4.
[0221] Optionally, in some embodiments, the terminal triggers N CSI measurement reports based on the first information. The time domain position of the terminal receiving the second information is less than or equal to T1 of the time domain position of receiving the first information. The terminal then transmits the N CSI measurement reports based on the second information.
[0222] If the time domain position at which the terminal receives the second information is greater than the time domain position at which it receives the first information, then the terminal will abandon the transmission of the N CSI measurement reports, or report placeholder information, or report indication information of invalid CSI.
[0223] Alternatively, if the time domain position at which the terminal receives the second information is greater than the time domain position at which it receives the first information, the terminal continues to transmit the N CSI measurement reports.
[0224] Where N is greater than or equal to 1.
[0225] Optionally, in some embodiments, if the terminal receives first information at M different time-domain locations, a CSI measurement reporting is triggered. The terminal receives second information, indicating the transmission of the M CSI measurement reports. The time-domain location at which the terminal receives the second information is less than or equal to T1 compared to the time-domain location at which it receives M1 pieces of first information, and greater than T1 compared to the time-domain location at which it receives M2 pieces of second information. Based on the second information, the terminal transmits the M1 CSI measurement reports and abandons the transmission of the M2 CSI measurement reports (or reports indication information for invalid CSI).
[0226] Optionally, in some embodiments, when a terminal triggers a CSI measurement, after the terminal receives the time of the triggered CSI-RS, the time of the CSI measurement, or the time after receiving the time domain location of the first information plus the CSI processing time, or the time of the CSI reference resource, or the time of the CSI measurement trigger, or the time of the CSI report generation, or the time when the CSI report is in a ready state, and after a preset time (T1 or T2) has elapsed, the terminal discards the CSI report corresponding to the CSI measurement.
[0227] Furthermore, the terminal does not expect the network-side device to trigger the transmission of the CSI report corresponding to the CSI measurement.
[0228] Optionally, the time-domain location for receiving the second information can also be the transmission time of the CSI report indicated by the second information. For example, if the transmission time of the CSI report indicated by the second information and the time-domain location for receiving the first information are less than or equal to T2, the terminal transmits one or more CSI reports based on the second information.
[0229] The aforementioned time-domain location for receiving the first information can also be the time when the CSI-RS is triggered, the time when the CSI is measured, the time when the time-domain location for receiving the first information is plus the CSI processing time, the time of the CSI reference resource, the time when the CSI measurement is triggered, the time when the CSI report is generated, or the time when the CSI report is in a ready state.
[0230] In this embodiment of the application, determining the above-mentioned time relationship based on the first rule can ensure the validity and timeliness of CSI reports, thereby improving the performance of CSI report transmission.
[0231] Optionally, in some embodiments, the network-side device triggers CSI measurement with first information and then triggers the transmission of CSI report with second information.
[0232] For example, the first information indicates at least one of the following:
[0233] CSI-RS transmission;
[0234] CSI measurement-related information, such as at least one of the following: measurement type, measurement configuration, and measurement resources;
[0235] Uplink transmission resources, such as first time domain resources;
[0236] Whether to submit a CSI report.
[0237] For example, the second information indicates at least one of the following:
[0238] Whether to submit CSI reports, for example, whether to carry CSI reports for UCI or MAC CE;
[0239] Information related to CSI reports includes, but is not limited to, at least one of the following: such as CSI report configuration information, CSI report type, and the carrier / BWP corresponding to the CSI report;
[0240] Whether to transmit upstream business data.
[0241] Optionally, in some embodiments, the first rule described above may include at least one of the following rules 1 to 3.
[0242] Rule 1: Send a CSI report on the most recent valid uplink resource after the CSI measurement; the CSI measurement may be triggered periodically or by aperiodic dynamic signaling.
[0243] Optionally, the time interval between the time domain location of the measured reference signal resources (one or more) and the time domain location of the uplink resources used to transmit the CSI report must be greater than or equal to a first preset time (i.e., a first time relationship). The triggering of the reference signal resources can be periodic or aperiodic triggered by dynamic signaling; the reference signal resources used for the measurements corresponding to the CSI reports included in the uplink resources must all satisfy the first time relationship. For example, if the uplink resources include K CSI reports, the reference signal resources corresponding to the measurements of these K CSI reports must all satisfy the first time relationship.
[0244] Optionally, the time when a CSI measurement is triggered and the uplink resources used to transmit the CSI report must be greater than or equal to a second preset time (i.e., a second time relationship). Specifically, the CSI measurement trigger times corresponding to the CSI reports included in the uplink resources must all satisfy this second time relationship. For example, if the uplink resources include K CSI reports, the CSI measurement trigger times corresponding to these K CSI reports must all satisfy the second time relationship.
[0245] Optionally, the time when the CSI report is generated and the uplink resources used to transmit the CSI report must be greater than or equal to a third preset time (i.e., a third time relationship). The time when the CSI report is generated can be periodically determined or indicated non-periodically by dynamic signaling. The time when the CSI report is generated can also be expressed as the time when the CSI report is in a ready state.
[0246] Rule 2: Send the CSI report on the most recent valid uplink resource after the second time point. The second time point is the time position determined based on the time domain position of receiving the first information and a fourth preset time. For example, the second time point is the time position of receiving the first information plus the CSI processing time.
[0247] Rule 3: A CSI report is sent on the most recent valid uplink resource after the CSI measurement, and the priority of the transmitted CSI report is higher than or equal to a preset priority. The priority of the CSI report must satisfy at least one of the following:
[0248] The priority of the CSI report is predefined or network-configured; the priority of this CSI report is either physical layer priority or MAC layer priority, which can be understood as the priority of the data carried.
[0249] Optionally, in some embodiments, the time interval between the uplink resource transmitting the CSI report and the first moment is determined to be less than T2 according to rule 1, rule 2 or rule 3 above.
[0250] Optionally, the aforementioned uplink resources can be represented as PUSCH resources, PUCCH resources, semi-statically configured PUSCH resources, semi-statically configured PUCCH resources, dynamically scheduled PUSCH resources, dynamically scheduled PUCCH resources, etc.
[0251] Optionally, the method for determining the validity of uplink resources may further include at least one of the following:
[0252] There is no overlap with the time-domain resources of common reference signals (synchronization signals, SSB, etc.) or the semi-statically configured DL time-domain resources;
[0253] Given a HARQ process;
[0254] Uplink resources that are only scheduled for new data transmission, i.e., uplink resources that do not include retransmission data.
[0255] Optionally, in some embodiments, multiple triggered partial CSI reports may be transmitted based on the second information.
[0256] For example, the terminal triggers M CSI measurements based on one or more first pieces of information or preset events, generates a CSI report, or obtains / determines the information carried in the CSI report; the terminal transmits N CSI reports based on second information, and the N CSI reports are partial CSI reports corresponding to the M CSI measurements triggered above.
[0257] Optionally, the aforementioned CSI report may be a CSI measurement triggered by a first piece of information, or a CSI report corresponding to one of a plurality of CSI measurements triggered by a first piece of information.
[0258] Optionally, the information indicated by the second information can be referred to the above embodiments and will not be repeated here. It should be noted that each piece of information indicated by the second information can be configured with a corresponding candidate list value through RRC, and the second information indicates one of the candidate values or indices.
[0259] For example, such as Figure 5 As shown, the first DCI (i.e., the first message) triggers the transmission of CSI-RS1 and CSI-RS2 and CSI measurements. The second DCI (i.e., the second message) triggers the transmission of the CSI measurement report corresponding to CSI-RS1.
[0260] Optionally, in some embodiments, multiple triggered partial CSI reports may be transmitted based on the second information.
[0261] For example, the terminal triggers M CSI measurements based on one or more first information or preset events, generates a CSI report, or obtains / determines the information carried in the CSI report; the terminal transmits N CSI reports based on second information, which may be CSI measurements triggered by multiple first information, or CSI reports of multiple CSI measurements triggered by a period or preset event.
[0262] Optionally, the terminal may receive the second information and transmit a CSI report corresponding to some or all of the triggered CSI measurements.
[0263] For example, such as Figure 6 As shown, the first DCI (i.e., the first message) triggers the transmission of CSI-RS1 and CSI-RS2 and CSI measurements. The second DCI (i.e., the second message) triggers the transmission of the CSI measurement report corresponding to CSI-RS1 and the CSI measurement report corresponding to CSI-RS2.
[0264] Optionally, the information indicated by the second information includes at least one of the following:

[0272] CSI measurement configuration number;
[0273] The trigger state number;
[0274] Types of CSI measurement reports, such as RSRP, L1-SINR, CSI, CQI, PMI, RI, CLI, etc.
[0275] First time information, based on the reception time of second information and the first time information, determines a first time region, which is a period of time prior to the reception time of the second information. CSI measurement reports triggered within this time region are all transmitted based on the second information. The first time information may indicate at least one of the following: time offset, time region length, etc.
[0276] The transmission information of the CSI report may include at least one of the following: whether the transmission of the CSI report is enabled; the first transmission resource; the maximum payload size of the CSI; the Beta offset; and the modulation and coding scheme (MCS). If the CSI report is transmitted with MAC information, the network-side device may indicate the MCS or modulation scheme corresponding to the transmission of the CSI report.

[0280] Community information, such as the community number served;
[0281] TRP information, such as TRP number and TRP spatial characteristics.
[0282] Optionally, the specific implementation method may differ depending on the content indicated by the second information. For example, it may include the following implementation methods:
[0283] Method 1: The second information can indicate the activation of CSI report transmission. Based on the second information, the terminal transmits the corresponding CSI reports for all triggered CSI measurements.
[0284] Method 2: The second information may indicate the enablement of CSI report transmission, as well as the number of one or more corresponding CSI reporting configurations. Based on the second information, the terminal transmits the CSI reports corresponding to the CSI measurement reports triggered by these CSI reporting configurations. The network-side device indicating one or more CSI reporting configurations that need to transmit CSI reports typically refers to CSI reporting configurations that have already triggered CSI measurements.
[0285] Method 3: The second information may indicate the enablement of CSI report transmission, as well as one or more CSI measurement reporting types. Based on the second information, the terminal transmits the CSI reports corresponding to these triggered CSI measurement reporting types.
[0286] Method 4: One or more first messages trigger the transmission of one or more CSI-RS and CSI measurements. The second message can indicate the CSI-RS number. Based on the second message, the terminal transmits the CSI report obtained from the corresponding CSI-RS measurement.
[0287] Method 5: The second information can indicate the transmission of the trigger state. Based on the second information, the terminal transmits the CSI report of the CSI measurement corresponding to the indicated trigger state.
[0288] Optionally, the terminal may perform the following actions based on the content indicated by the second information:
[0289] The CSI reporting configuration, which is the second information indication expected by the terminal, has already triggered CSI measurements;
[0290] or,
[0291] The terminal only reports the corresponding CSI report for CSI reporting configurations that have triggered CSI measurements in the CSI reporting configuration indicated by the second information; optionally, for CSI reporting configurations that have not triggered CSI measurements in the CSI reporting configuration indicated by the second information, the terminal reports the CSI report of previously triggered CSI measurements, i.e., the old CSI report.
[0292] Optionally, in some embodiments, the transmission resources (i.e., the first uplink resources) reported by CSI can be semi-statically configured PUSCH resources or dynamically scheduled PUSCH resources.
[0293] Optionally, for semi-statically configured PUSCH resources, the network-side device can configure at least one of the following:

[0313] Optionally, in some embodiments, the second information may include the dynamic signaling indication.
[0314] Optionally, in some embodiments, the mapping method for multiple CSI reports transmitted in uplink resources is as follows:
[0315] If multiple triggered CSI measurement reports are transmitted based on information indicated by the second information or the first rule, the mapping of these multiple CSI reports on transmission resources includes:
[0316] Reports of CSI measurements triggered earlier are listed in the order of their triggering time, for example, reports of CSI measurements triggered later are listed first.
[0317] Arranged according to the CSI measurement report numbering order, such as ascending (or descending) order of CSI measurement report numbers;
[0318] According to the CSI reporting configuration number order corresponding to the CSI measurement, such as sorted in ascending order of CSI reporting configuration number;
[0319] CSI reports are arranged according to their priority, from highest to lowest. The priority of a CSI report can be determined based on at least one of the following: CSI type, cell index, and CSI reporting configuration ID. Specifically, for type: Application-specific CSI (A-CSI) > SP-CSI transmitted via PUSCH resources > SP-CSI transmitted via PUSCH resources > Periodic CSI (P-CSI). ">" indicates higher priority. For cell index: the smaller the cell index, the higher the priority; for CSI reporting configuration ID: the smaller the ID, the higher the priority.
[0320] Map according to the parts contained in the CSI report, such as part 1, part 2, or in the order of part 1 first and then part 2.

[0338] Community information, such as the community number served;
[0339] TRP information, such as TRP number and spatial characteristics.
[0340] Optionally, the above one or more CSI measurements correspond to one or more CSI reports.
[0341] Optionally, the information indicated by the first information may also include at least one of the following:
[0342] Instructions on whether to transmit CSI measurement reports. For example, if the first message indicates that CSI measurement reports should not be transmitted, the terminal will only perform CSI measurements and transmit the CSI measurements based on the subsequently received second message.
[0343] The first information indicates a delay in CSI measurement reporting. At this time, the terminal can select uplink resources that meet the conditions to transmit the CSI report after the CSI measurement is completed, based on preset rules; or the terminal can transmit the delayed CSI report based on subsequently scheduled uplink resources.
[0344] For example, the first message is sent by the network, indicating the triggering of one or more CSI measurements; at the same time, it indicates the transmission of one or more CSI-RS (reference signals).
[0345] The terminal receives the first information, and the triggered CSI-RS transmission satisfies the first time, that is, it is greater than or equal to the first time.
[0346] The terminal receives the first information, which satisfies the second time with the triggered CSI measurement, i.e., is greater than or equal to the second time.
[0347] Optionally, the first information indicates a time offset (i.e., a first time offset) or a time position. This time position is the earliest time point at which the network wants to obtain the CSI report. The terminal transmits the CSI report at a time point no earlier than the earliest time point, according to the first rule or the instruction of the network-side device. In this way, the terminal can ensure that the CSI reports are ready when they are transmitted.
[0348] The time offset or time position can be explicitly indicated by the indication field in the first information; or determined based on the information indicated by the indication field in the first information, such as the HARQ-ACK feedback time position indicated when the first information is a DL grant, or the PUSCH transmission time position indicated when the first information is a UL grant, etc.
[0349] Alternatively, the first information may not include indication of the time offset or time position; that is, the earliest time point at which the network expects to obtain the CSI report is not explicitly indicated. The time offset or time position is determined based on the time point of the CSI measurement resource triggered by the first information and a preset (predefined or preconfigured) timeline.
[0350] Optionally, in some embodiments, the terminal performs CSI measurements in a periodic or semi-persistent manner. For example, the terminal triggers one or more CSI measurements (and generates a CSI report) based on first information, where the first information is an RRC configuration or a MAC message, and the CSI measurements are periodic or semi-persistent.
[0351] Scenario 1: The first information indicates the CSI measurement period and the trigger time for each CSI measurement; based on the second information or the first rule, the terminal transmits one or more CSI reports using PUSCH resources after the trigger time of the aforementioned CSI measurement; these one or more CSI reports correspond to one or more CSI measurements in one or more periods. In this case, the transmission of CSI measurements and CSI reports is as follows: Figure 7 As shown.
[0352] Optionally, the time interval between the CSI measurement trigger time and the time domain location of the PUSCH resource used to transmit the CSI report must be greater than or equal to the second preset duration.
[0353] Scenario 2: The first information indicates the period of CSI measurement and the time of reference resource transmission for each period; based on the second information or the first rule, the terminal transmits one or more CSI reports via PUSCH resources after the aforementioned reference resource transmission time; these one or more CSI reports correspond to CSI measurements for one or more periods of reference resources. In this case, the transmission of CSI measurements and CSI reports is as follows: Figure 8 As shown.
[0354] Case 3: The information indicated by the first information includes the period of CSI measurement and the time when the CSI report is generated in each period (which can also be expressed as the CSI report information being ready); the terminal transmits one or more CSI reports using PUSCH resources after the time when the aforementioned CSI report is generated, based on the second information or the first rule; the one or more CSI reports correspond to the CSI reports generated in one or more periods.
[0355] Optionally, the interval between the time when the CSI report is generated and the time-domain location of the PUSCH resource used to transmit the CSI report must be greater than or equal to the third preset duration.
[0356] Optionally, the CSI measurement corresponding to the CSI report is based on CSI-RS resources prior to the first time point, specifically no later than the first time point. The first time point includes: the time position of the CSI reference resource or the time when the CSI report is generated, and the time position determined by the time offset from the network configuration (or predefined). In this case, the transmission of CSI measurements and CSI reports is as follows: Figure 9 As shown.
[0357] Optionally, in some embodiments, the terminal may trigger CSI measurements based on preset events.
[0358] Optionally, the terminal sends indication information to the network, which indicates at least one of the following: a preset event, the type of reference signal, the number of the reference signal, the number of the reference signal set, the number of the CSI reporting configuration, the number of the CSI measurement configuration, etc.
[0359] The terminal receives the second information sent by the network-side device and transmits the CSI report corresponding to the aforementioned CSI measurement based on the second information.
[0360] Preset events include at least one of the following:
[0361] Beam management related events, such as beam measurement quality being greater than, equal to, or less than a preset threshold;
[0362] Wireless link monitoring related events;
[0363] Channel measurement related events, such as Layer 1 RSRP or Layer 1 SINR being greater than or equal to a preset threshold, or Layer 1 RSRP or Layer 1 SINR being less than or equal to a preset threshold;
[0364] Mobility-related events, such as Layer 3 measurement results meeting predefined conditions, neighboring cell measurement signal quality being greater than or equal to a preset threshold, and serving cell signal quality being less than a preset threshold.
[0365] Optionally, in some embodiments, the network-side device may configure multiple reference resource configuration information, and the terminal performs CSI measurements based on the reference resource information indicated by the first indication information. The reference resource information indicated by the first indication information corresponds to one or more reference signal resources in the reference resource configuration.
[0366] Optionally, in some embodiments, the network configures multiple CSI reporting configurations, and performs CSI measurements based on the first information indicating the CSI reporting configuration.
