Description

Technical Field

[0001] This application relates to the field of mobile communications, and in particular to a method, apparatus, device, and storage medium for reporting tracking reference signal information. Background Technology

[0002] In related technologies, in schemes that use Track Reference Signal (TRS)-assisted paging to save power, the network device configures multiple sets of TRS resources and dynamically instructs the terminal device to detect TRS through Downlink Control Information (DCI).

[0048] First, the relevant technologies involved in the embodiments of this application will be introduced:

[0049] Paging pre-synchronization based on Synchronization Signal Block (SSB):

[0050] In power-saving mode, idle or inactive terminal devices need to synchronize with the radio interface in advance to demodulate paging messages periodically sent by the network equipment; this is called paging pre-synchronization. Considering the long interval between two consecutive paging messages, such as... Figure 1In the illustrated scheme, idle or inactive terminal devices need to be woken up in advance before the paging time and detect multiple SSBs to restore wireless synchronization. The number of SSBs to be detected during paging pre-synchronization depends on the terminal device's signal-to-noise ratio (SNR) status. For example, when the SNR is poor, the terminal device needs to detect at least three SSBs before the paging time. Assuming an SSB period of 20 milliseconds, this means the terminal device needs to be woken up 80 milliseconds in advance, resulting in significant additional power consumption.

[0051] Track Reference Signal (TRS):

[0052] TRS is used to track deviations in the time and frequency domains. It is a collection of resources containing Channel State Information-Reference Signals (CSI-RS) with a special time-frequency structure. For example... Figure 2 As shown, the basic characteristics of the time-frequency structure of TRS include: single-port; three CSI-RS resources within the frequency domain corresponding to a resource block (RB); transmission in two consecutive time slots; and a minimum time interval of four Orthogonal Frequency Division Multiplexing (OFDM) symbols and four subject-carrier symbols between two TRS resources within the same time slot, which can be simply referred to as sparsity. When receiving downlink data, connected terminal devices need to continuously and dynamically track the time-frequency deviation. Demodulating the TRS reference symbols enables the terminal device to track and compensate for the time-frequency deviation in a timely manner, thereby effectively improving downlink transmission performance.

[0053] TRS-assisted paging pre-synchronization:

[0054] To further reduce the power consumption required for pre-synchronization of terminal devices before receiving paging messages, related technologies have introduced dedicated TRS-based configuration and transmission for idle or inactive terminal devices, serving as the pre-synchronization function for these devices. For example... Figure 3 As shown, the TRS-assisted paging pre-synchronization scheme, compared to the SSB-based paging pre-synchronization scheme, reduces the time that idle or inactive terminal devices need to be woken up before the paging time, thereby achieving the effect of saving power consumption.

[0055] TRS resource allocation:

[0056] TRS resource configuration is sent by network devices to terminal devices via System Information Block (SIB) 17. Currently, in related technologies, SIB 17 includes configuration information for up to 64 TRS resource sets. The configuration information for each TRS resource set includes: Power Control Offset, time-domain symbol position, spatially related SSB number, TRS transmission period and offset, number of TRS resources, TRS validity period, and packet number. If the TRS configuration in SIB 17 is effective, it will be used in conjunction with dynamic indications based on DCI.

[0057] For example, the resource configuration of TRS is as follows:

[0058]

[0059] In application scenarios where the terminal device enables TRS as a pre-synchronization auxiliary signal, the network device adds six bits of mapping information to the DCI 1_0 or DCI 2_7 format to explicitly and dynamically notify the terminal device. The network device then sends the packet number corresponding to the TRS. It is important to emphasize that each packet number corresponds to multiple TRS resource sets. After receiving this packet number information, the terminal device demodulates the multiple TRS resource sets corresponding to that number and estimates the time offset and frequency offset parameters to perform pre-synchronization calculations before the paging time. The effective duration of the TRS depends on the configuration time in SIB17 and the system message update cycle.

[0060] In related technologies, the TRS-assisted paging pre-synchronization scheme requires network devices to configure multiple TRS resource sets within system messages and dynamically trigger the terminal device's TRS detection process via DCI. However, this scheme lacks a feedback mechanism from the terminal device regarding TRS, failing to form an effective closed-loop coupling between network device configuration and terminal device functionality. This reduces the efficiency of configuring and utilizing the TRS resource sets transmitted by the network device for paging pre-synchronization, and also increases the power consumption overhead of the terminal device's detection to some extent. Overall, the TRS-assisted paging pre-synchronization scheme in related technologies has the following main drawbacks:

[0061] (1) On the network equipment side, multiple sets of TRS resource sets need to be transmitted to ensure the reliability of terminal equipment paging pre-synchronization;

[0062] • Impact: Increases TRS resource overhead and reduces the number of idle or inactive terminal devices that can be supported in the cell;

[0063] • Causes: In the spatial domain, there is a lack of effective beam management for terminal devices; in the temporal domain, there is a lack of determination of the optimal location information for TRS; and functionally, it is impossible to know how the terminal devices use TRS resources.

[0064] (2) On the terminal device side, the detection of multiple sets of candidate TRS resources brings additional power consumption overhead.

[0065] To address the aforementioned issues, this application provides a method for reporting Tracking Reference Signal Information, which supports terminal devices in reporting the usage or measurement status of TRS resources to network devices. This method helps network devices to configure TRS resources more effectively, avoids resource waste, and saves power consumption.

[0074] Figure 5 This illustration shows a flowchart of a method for reporting tracking reference signal information provided in some exemplary embodiments of this application. The method is described by, for example... Figure 4 Taking the terminal device shown as an example, the method includes at least some of the following steps:

[0075] Step 510: Measure at least one TRS resource set from multiple TRS resource sets;

[0076] Multiple TRS resource sets are used for pre-synchronization before receiving paging messages. These multiple TRS resource sets are configured by the network device to the terminal device.

[0077] The configuration information for each TRS resource set includes at least one of the following: PowerControlOffset, time-domain symbol position, spatially related SSB number, TRS transmission period and offset, number of TRS resources, TRS effective time length, and group number.

[0078] Measuring at least one set of TRS resources can be understood as detecting at least one set of TRS resources in the time domain and / or frequency domain.

[0079] Step 530: Send TRS reporting information corresponding to at least one set of TRS resource sets.

[0080] After measuring at least one set of TRS resources, the terminal device sends the TRS reporting information corresponding to that set of TRS resources to the network device. The TRS reporting information corresponding to at least one set of TRS resources can be understood as the measurement results related to at least one set of TRS resources.

[0082] Figure 6 This illustration shows a flowchart of a method for reporting tracking reference signal information provided in some exemplary embodiments of this application. The method is described by, for example... Figure 4 Taking the terminal device shown as an example, the method includes at least some of the following steps:

[0083] Step 610: Receive TRS resource configuration;

[0084] The terminal device receives the TRS resource configuration sent by the network device. The TRS resource configuration is used to configure multiple sets of TRS resources. These multiple sets of TRS resources are used for pre-synchronization before receiving paging messages.

[0085] The configuration information for each TRS resource set includes at least one of the following: power control offset, time domain symbol position, spatially related SSB number, TRS transmission period and offset, number of TRS resources, TRS effective time length, and group number.

[0086] Step 620: Receive TRS configuration report;

[0087] The terminal device receives the TRS reporting configuration sent by the network device. The TRS reporting configuration is used to configure the TRS reporting parameters corresponding to at least one set of TRS resources.

[0088] In some embodiments, the TRS reporting configuration includes at least one of the following:

[0089] • TRS reports the configuration number;

[0090] • Report the TRS resource set;

[0091] • TRS reporting cycle;

[0092] • TRS reporting content.

[0093] In some embodiments, the TRS reporting content includes at least one of the following:

[0094] • Acknowledgement (ACK) based on TRS measurement results;

[0095] • Negative Acknowledgement (NACK) based on TRS measurement results;

[0096] • ACK based on paging result;

[0097] • NACK based on paging results;

[0098] • Optimal TRS resource set;

[0099] • The number of optimal TRS resource sets;

[0103] • The number of TRS resource sets whose TRS measurement results rank in the top N of at least one TRS resource set, where N is a positive integer;

[0104] • The effective time interval between TRS and SSB.

[0105] The first threshold is either predefined, configured by the network device, or determined autonomously by the terminal device.

[0106] In some embodiments, the TRS resource configuration is carried in the first System Information Block (SIB) information, and the TRS reporting configuration is carried in the second SIB information;

[0107] The first SIB information and the second SIB information may be the same or different.

[0108] In some embodiments, the TRS resource configuration is carried in the SIB information, and the TRS reporting configuration is carried in the Radio Resource Control (RRC) information.

[0109] Step 630: Receive TRS measurement indication;

[0110] TRS measurement indication is used to instruct the terminal device to measure at least one set of TRS resource sets. The TRS measurement indication includes at least one set of TRS resource set numbers and / or TRS reporting configuration numbers.

[0111] The TRS measurement indication is carried in the DCI.

[0112] Step 640: Measure at least one TRS resource set from multiple TRS resource sets;

[0113] Measuring at least one set of TRS resources can be understood as detecting at least one set of TRS resources in the time and / or frequency domains. The measurement results are used to estimate the time offset and / or frequency offset parameters corresponding to the TRS resource set.

[0114] In some embodiments, the terminal device measures at least one set of TRS resources from multiple sets of TRS resource sets based on the TRS measurement indication; or, the terminal device measures at least one set of TRS resource sets and SSB from multiple sets of TRS resource sets based on the TRS measurement indication.

[0120] In summary, the method provided in this application offers a complete mechanism for configuring, measuring, and providing feedback on TRS resource sets. It supports terminal devices in sending corresponding TRS reporting information to network devices after measuring TRS, enabling network devices to obtain the TRS measurement results or usage status of terminal devices. This facilitates the formation of a closed-loop coupling between network device configuration and terminal device feedback, providing support for network devices to configure TRS resources more effectively, reduce resource overhead, and save measurement power consumption of terminal devices.

[0121] Figure 7 This illustration shows a flowchart of a method for reporting tracking reference signal information provided in some exemplary embodiments of this application. The method is described by, for example... Figure 4 Taking the network device and terminal device shown as examples, the method includes at least some of the following steps:

[0122] Step 701: The network device sends the TRS resource configuration;

[0123] TRS resource configuration is used to configure multiple sets of TRS resources. Multiple sets of TRS resources are used for pre-synchronization before receiving paging messages.

[0124] The configuration information for each TRS resource set includes at least one of the following: power control offset, time domain symbol position, spatially related SSB number, TRS transmission period and offset, number of TRS resources, TRS effective time length, and group number.

[0125] TRS resource configuration is carried in the SIB and sent to idle, inactive, or connected terminal devices.

[0126] Step 702: The terminal device determines multiple sets of TRS resources;

[0127] The terminal device interprets the SIB and determines multiple sets of TRS resources based on the received TRS resource configuration.

[0128] Step 703: The network device sends a TRS configuration report;

[0129] The TRS reporting configuration is used to configure the TRS reporting parameters corresponding to at least one set of TRS resources.

[0130] The TRS reporting configuration is carried in the SIB or RRC message and sent to idle terminal devices, inactive terminal devices, or connected terminal devices.

[0131] In some embodiments, the TRS reporting configuration includes at least one of the following:

[0132] • TRS reports the configuration number;

[0133] Used to distinguish the TRS reporting configurations corresponding to different TRS resource sets, and / or used to distinguish the TRS reporting configurations of subsequent DCI dynamic indications.

[0134] • Report the TRS resource set (reportTRSResourceSet);

[0135] This is used to indicate the TRS resource set measured by the terminal device, and / or the TRS resource set that instructs the terminal device to send corresponding TRS reporting information. Optionally, an explicit indication method using bit mapping can be used. For example, if the SIB configures 64 TRS resource sets for paging pre-synchronization, `reportTRSResourceSet` uses 64 bits to indicate a subset of the 64 TRS resource sets. This subset can include a single TRS resource set, multiple TRS resource sets, or all 64 TRS resource sets. For instance, when the network device needs to obtain TRS reporting information from the entire set of 64 TRS resource sets, or when the paging failure rate exceeds a threshold, the TRS resource subset includes all 64 TRS resource sets.

[0136] • TRS reporting period (reportPeriodType);

[0137] The period at which the terminal device sends TRS reporting information includes at least one of the following: periodic sending, non-periodic sending, and semi-persistent sending.

[0138] When the TRS reporting cycle indicates periodic transmission, the terminal device periodically sends TRS reporting information based on an integer multiple of the paging cycle. Optionally, the network device explicitly configures this integer value.

[0139] When the TRS reporting period indicator is sent non-periodically, the terminal device sends TRS reporting information based on the instruction from the network device.

[0140] When the TRS reporting cycle indicates semi-persistent transmission, the terminal device transmits TRS reporting information semi-persistently based on integer multiples of the paging cycle. When a preset condition is met, the transmission of TRS reporting information ends. For example, if the preset condition is successful paging, then during the semi-persistent transmission of TRS reporting information, the terminal device will stop transmitting TRS reporting information after the first successful paging.

[0141] • TRS report content (reportQuantity).

[0142] In some embodiments, the TRS reporting content includes at least one of the following:

[0143] • Acknowledgement (ACK) based on TRS measurement results;

[0144] After measuring at least one set of TRS resources, the terminal device obtains the TRS measurement results of at least one set of TRS resources, estimates the time-frequency deviation based on the TRS measurement results, compares the estimated time-frequency deviation with the SSB measurement results, and if the comparison results show that the estimated time-frequency deviation is valid, then ACK is fed back.

[0145] • Negative Acknowledgement (NACK) based on TRS measurement results;

[0146] After measuring at least one set of TRS resources, the terminal device obtains the TRS measurement results of at least one set of TRS resources. Based on the TRS measurement results, it estimates the time-frequency deviation and compares the estimated time-frequency deviation with the SSB measurement results. If the comparison results show that the estimated time-frequency deviation is invalid, it feeds back NACK.

[0147] In some embodiments, if the network device continuously receives TRS reporting content including NACK during the first time period, the configuration mode of TRS-assisted paging pre-synchronization is temporarily adjusted to cancel, that is, the TRS-assisted paging pre-synchronization scheme is not used during the second time period.

[0148] • ACK based on paging result;

[0149] After measuring at least one set of TRS resources, the terminal device obtains the TRS measurement results of at least one set of TRS resources, estimates the time-frequency deviation based on the TRS measurement results, demodulates the paging message based on the estimated time-frequency deviation, and if the paging message is successfully demodulated, that is, the paging message is successfully received, then an ACK is sent back.

[0150] • NACK based on paging results;

[0151] After measuring at least one set of TRS resources, the terminal device obtains the TRS measurement results of at least one set of TRS resources, estimates the time-frequency deviation based on the TRS measurement results, demodulates the paging message based on the estimated time-frequency deviation, and if the demodulation of the paging message fails, that is, the paging message is not successfully received, then NACK is fed back.

[0152] In some embodiments, if the network device continuously receives TRS reporting content including NACK during the first time period, the configuration mode of TRS-assisted paging pre-synchronization is temporarily adjusted to cancel, that is, the TRS-assisted paging pre-synchronization scheme is not used during the second time period.

[0153] • Optimal TRS resource set;

[0154] After measuring at least one set of TRS resource sets, the terminal device obtains the TRS measurement results of at least one set of TRS resource sets. Based on the TRS measurement results of at least one set of TRS resource sets, the time-frequency deviation of each set of TRS resource sets is estimated. Based on the time-frequency deviation estimation results of at least one set of TRS resource sets, the optimal TRS resource set is determined.

[0155] For example, the time-frequency deviation estimation results of at least one set of TRS resource sets are compared with the SSB measurement results. The at least one set of TRS resource sets whose time-frequency deviation estimation results are closest to the SSB measurement results is determined as the optimal TRS resource set. Alternatively, paging messages are demodulated based on the time-frequency deviation estimation results of at least one set of TRS resource sets. The at least one set of TRS resource sets corresponding to the time-frequency deviation estimation results of successfully demodulated paging messages is the optimal TRS resource set. Or, the optimal TRS resource set can be understood as the TRS resource set with the highest beam overlap between the beam and the terminal device among at least one set of TRS resource sets.

[0156] In some embodiments, the network device adjusts the TRS resource set configured for the terminal device based on the optimal TRS resource set in the reported content. For example, the network device filters and reduces non-optimal TRS resource sets from multiple sets of TRS resource sets, thereby reducing TRS resource overhead.

[0157] • The number of optimal TRS resource sets;

[0158] After measuring at least one set of TRS resource sets, the terminal device obtains the TRS measurement results of at least one set of TRS resource sets. Based on the TRS measurement results of at least one set of TRS resource sets, the time-frequency deviation of each set of TRS resource sets is estimated. Based on the time-frequency deviation estimation results of at least one set of TRS resource sets, the number of optimal TRS resource sets is determined; or, based on the TRS measurement capability of the terminal device, the number of optimal TRS resource sets is determined.

[0159] • A set of TRS resources whose TRS measurement results are better than the first threshold;

[0160] After measuring at least one set of TRS resource sets, the terminal device obtains the TRS measurement results of at least one set of TRS resource sets. Based on the TRS measurement results of at least one set of TRS resource sets, the time-frequency deviation of each set of TRS resource sets is estimated. Based on the time-frequency deviation estimation results of at least one set of TRS resource sets, the TRS resource sets whose TRS measurement results are better than a first threshold are determined.

[0161] The first threshold is predefined, configured by the network device, or determined autonomously by the terminal device.

[0162] • The number of TRS resource sets whose TRS measurement results are better than the first threshold;

[0163] Similar to the number of optimal TRS resource sets, it will not be elaborated further.

[0164] • Among at least one set of TRS resources, the TRS measurement results are ranked in the top N TRS resource sets, where N is a positive integer;

[0165] After measuring at least one set of TRS resource sets, the terminal device obtains the TRS measurement results of at least one set of TRS resource sets. Based on the TRS measurement results of at least one set of TRS resource sets, the time-frequency deviation of each set of TRS resource sets is estimated. Based on the time-frequency deviation estimation results of at least one set of TRS resource sets, the TRS resource sets whose TRS measurement results rank in the top N among the at least one set of TRS resource sets are determined.

[0166] • The number of TRS resource sets whose TRS measurement results rank in the top N of at least one TRS resource set, where N is a positive integer;

[0167] Similar to the number of optimal TRS resource sets, it will not be elaborated further.

[0168] • The effective time interval between TRS and SSB.

[0169] Because there are three period configurations—SSB period, TRS period, and paging period—and these three period configurations may correspond to different time slot offsets, there are multiple combinations of TRS and SSB intervals. Based on this, the terminal device obtains the effective interval between the TRS and SSB time slots based on the time-frequency deviation estimation results, and reports this information to the network device for subsequent TRS resource configuration optimization.

[0170] like Figure 8 As shown, after measuring the TRS resource set and SSB, the terminal device determines the effective time interval of the TRS and SSB to be 7 time slots based on the time-frequency deviation estimation results. In other words, TRS resource sets with an interval of 7 time slots or less from the SSB are valid TRS resource sets for the terminal device. After obtaining this information, the network device can subsequently configure TRS resource sets with an interval of 7 time slots or less from the SSB for the terminal device, reducing TRS resource sets with an interval greater than 7 time slots from the SSB, thus reducing TRS resource waste and improving the effectiveness of TRS resource configuration.

[0171] For example, the TRS reporting configuration corresponding to a set of TRS resources is as follows:

[0172]

[0173] Step 704: The terminal device determines the TRS reporting configuration set;

[0174] The terminal device interprets the SIB or RRC message and determines the TRS reporting configuration set based on the received TRS reporting configuration.

[0175] Step 705: The network device sends a TRS measurement indication;

[0176] The TRS measurement indication is used to instruct the terminal device to measure at least one set of TRS resource sets. The TRS measurement indication includes at least one set of TRS resource set numbers and TRS reporting configuration numbers.

[0177] At least one set of TRS resource set numbers is used to instruct the terminal device to measure at least one set of TRS resource sets corresponding to that number.

[0178] The TRS reporting configuration number is used to instruct the terminal device to send TRS reporting information based on the TRS reporting configuration corresponding to that number.

[0179] TRS measurement indications are carried and transmitted in the DCI. For example, they are carried and transmitted in DCI 1_0 or DCI 2_7.

[0180] In some embodiments, at least one set of TRS resource set numbers and TRS reporting configuration numbers are carried in two DCIs respectively, or at least one set of TRS resource set numbers and TRS reporting configuration numbers are carried in one DCI.

[0181] For example, an explicit indication field for the TRS reporting configuration is added to DCI 1_0 or DCI 2_7. Taking PEI-RNTI scrambled DCI 2_7 as an example, the TRS reporting configuration is as follows:

[0182] The TRS report configuration indicator -X bits, where the number of bits is equal to the TRS-Idle-ReportConfig in the SIB / RRC message, or, if a TRS-Idle-ReportConfig number is configured, the number of bits is equal to log2(TRS-Idle-ReportConfig number). Otherwise, the number of bits is 0.

[0183] TRS report configuration indication–X bits, where the number of bitsis equal to the number of TRS-Idle-ReportConfig in SIB / RRC or log2(TRS-Idle-ReportConfig number)if ​​configured; 0bits otherwise.

[0184] Step 706: The terminal device determines at least one set of TRS resources and TRS reporting configuration indicated by the network device;

[0185] The terminal device interprets the DCI and, based on the received TRS measurement indication, determines at least one set of TRS resources and TRS reporting configuration indicated by the network device. This can also be understood as determining at least one set of TRS resources and TRS reporting configuration selected by the network device.

[0186] After receiving the DCI carrying the TRS reporting configuration number, the terminal device determines the corresponding TRS reporting configuration by querying the higher-level configuration in the SIB / RRC message, and then determines the subsequent TRS measurement behavior.

[0187] Step 707: The terminal device performs paging pre-synchronization;

[0188] In some embodiments, the terminal device measures at least one set of TRS resources based on TRS measurement indications, obtains an estimate of the time-frequency deviation corresponding to at least one set of TRS resources, and restores synchronization of the wireless interface based on the estimate of the time-frequency deviation.

[0189] In some embodiments, the terminal device measures at least one set of TRS resource sets and SSB based on TRS measurement indications, determines an estimate of time-frequency deviation based on the measurement results of at least one set of TRS resource sets and SSB measurement results, and restores synchronization of the wireless interface based on the estimate of time-frequency deviation.

[0190] Step 708: The network device sends a paging message;

[0191] A network device sends a paging message, triggering the paging process. The paging message carries the identifier of the terminal device, indicating that the network device has initiated a paging of the terminal device.

[0192] Step 709: The terminal device sends a paging response message;

[0193] When an idle or inactive terminal device receives a paging message, it sends a paging response message to respond to the paging message from the network device.

[0194] Step 710: At the paging completion time, the terminal device sends TRS reporting information;

[0195] After the paging process is completed, the terminal device re-establishes the RRC connection with the network device. During the RRC connection process, the terminal device sends TRS reporting information.

[0196] The TRS reporting information is carried in the RRC message and sent through the uplink logical channel.

[0197] For example, such as Figure 9As shown, in step 901, the terminal device sends an RRC Setup Request message; in step 902, the network device establishes a radio-side bearer and sends an RRC Setup message, such as an RRC Connection Reconfiguration message, to the terminal device; in step 903, the terminal device sends an RRC Setup Complete message, such as an RRC Connection Reconfiguration Complete message. TRS reporting information is carried in the RRC Setup Request message and / or the RRC Setup Complete message.

[0198] TRS reporting information includes the TRS reporting content indicated in the TRS reporting configuration, such as ACK based on paging results, the optimal TRS resource set, the number of optimal TRS resource sets, and the effective time interval between TRS and SSB.

[0199] Step 711: The network device sends the updated TRS resource configuration;

[0200] The network device updates the TRS resource configuration of the terminal device based on the TRS report information sent by the terminal device.

[0201] For example, such as Figure 10 As shown, based on the TRS reporting information, the network device determines the TRS measurement results or TRS usage of the terminal device, including the validity of TRS, the selection of the optimal TRS beam set, and the optimal TRS time domain allocation scheme. It then selects the optimal TRS resource set for the terminal device, adds the optimal TRS resource set to the TRS resource configuration, reduces the non-optimal TRS resource set, obtains the updated TRS resource configuration, and sends the updated TRS resource configuration to the terminal device.

[0202] The updated TRS resource configuration is carried in the SIB and sent to the terminal device.

[0203] Step 712: The network device sends an updated TRS reporting configuration;

[0204] The network device updates the TRS reporting configuration of the terminal device based on the TRS reporting information sent by the terminal device.

[0205] The updated TRS reporting configuration is used to configure the TRS reporting parameters corresponding to at least one updated set of TRS resources. The content of the TRS reporting configuration is referenced in step 703, and the updated at least one set of TRS resources is the at least one set of TRS resources included in the updated TRS resource configuration in step 711.

[0206] The updated TRS reporting configuration is carried in an SIB or RRC message and sent to the terminal device.

[0207] In summary, the method provided in this application offers a complete mechanism for configuring, measuring, and providing feedback on TRS resource sets. It supports terminal devices sending corresponding TRS reporting information to network devices after measuring TRS, enabling network devices to obtain the TRS measurement results or usage status of terminal devices. This facilitates closed-loop coupling between network device configuration and terminal device feedback. Specifically, it has the following advantages:

[0208] 1. Reduce the resource allocation overhead of TRS reference symbols on the network device side;

[0209] Through effective TRS reporting feedback from the terminal device side, the network device side optimizes resource management and time-domain allocation schemes (TRS / SSB intervals), improving the efficiency of allocating TRS resources and sending TRS reference symbols to terminal devices. With the total TRS resources remaining constant, more terminal devices within the same cell can achieve paging pre-synchronization.

[0210] 2. Improve the beam management performance of TRS;

[0211] Based on the TRS reporting information from the terminal devices, the network devices determine the optimal TRS resource set for the terminal devices and configure the optimal, suboptimal, or subsets of the TRS resource sets for the terminal devices, thereby better and more accurately adapting to the dynamic changes in the downlink channel. With the total TRS resources remaining constant, subsequent TRS resource configurations can also cover more beam directions.

[0212] 3. Further savings in power consumption of terminal devices;

[0213] Network devices send more concise and effective TRS resource sets to terminal devices based on TRS reporting information. This allows terminal devices to further avoid measuring non-optimal TRS resource sets, reduce power consumption waste during TRS resource set measurement, and reduce resource overhead during TRS resource set measurement.

[0214] 4. Improved configuration flexibility and comprehensiveness of reported content.

[0215] Network devices can flexibly combine TRS resource sets and TRS reporting configurations according to measurement needs, and can configure different TRS reporting configuration parameters for terminal devices in different scenarios.
