First, a description is given of a related art related to an embodiment of the present application:

paging pre-synchronization based on synchronization signal blocks (Synchronization Signal Block, SSB):

idle (Idle) or Inactive (Inactive) terminal devices in the power saving mode need to be synchronized with a wireless interface in advance, and Paging pre-synchronization for short, in order to demodulate Paging (Paging) information periodically transmitted by a network device. Considering the long period interval between two consecutive paging messages, as in the scheme shown in fig. 1, an idle or inactive terminal device needs to wake up in advance of the paging occasion and detect multiple SSBs to resume wireless synchronization. In the paging pre-synchronization process, the number of SSBs to be detected depends on the Signal-to-Noise Ratio (SNR) state of the terminal device. For example, when the signal-to-noise ratio state is poor, the terminal device needs to detect at least three SSBs before the paging occasion, and assuming that the SSB period is 20 ms, this means that the terminal device needs to wake up 80 ms in advance, which causes a large overhead of additional power consumption to the terminal device.

Tracking reference signal (TrackReferenceSignal, TRS):

the TRS is used to track the bias in the time and frequency domains, and is a set of resources that contain a channel state information Reference Signal (CSI-RS) with a special time-frequency structure. As shown in fig. 2, the basic features of the time-frequency structure of the TRS include: a single port; three CSI-RS resources are included in a frequency domain range corresponding to one resource block (ResourceBlock, RB); transmitting in two consecutive time slots (Slot); the minimum interval of two TRS resources in the same slot in the time domain is four orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbols, and the minimum interval in the frequency domain is four subcarriers (sub-carriers), which may be simply referred to as sparse characteristics. When receiving downlink data, the connected terminal equipment needs to continuously and dynamically track time-frequency deviation, and demodulate TRS reference symbols to enable the terminal equipment to track and timely compensate the time-frequency deviation, so that the transmission performance of the downlink direction is effectively improved.

TRS assisted based paging pre-synchronization:

in order to further reduce the power consumption required by the terminal device to perform pre-synchronization before receiving the paging message, in the related art, dedicated TRS-based configuration and transmission are introduced for idle or inactive terminal devices, for the pre-synchronization function of the terminal device. As shown in fig. 3, compared with the paging pre-synchronization scheme based on SSB, the paging pre-synchronization scheme based on TRS assistance enables idle or inactive terminal devices to reduce the time required to wake up in advance before the paging occasion, thereby achieving the effect of saving power consumption.

Resource configuration of TRS:

the TRS resource configuration is that the network device sends to the terminal device through a system message block (SystemInformationBlock, SIB) 17, and the SIB17 in the related art includes configuration information of 64 sets of TRS resource sets at most. Configuration information for each TRS resource set, including: power control offset (powercontrol offset), time domain symbol position, spatially related SSB number, TRS transmission period and offset, TRS resource number, TRS effective time length, packet number. If the TRS configuration of SIB17 is in effect, a DCI-based dynamic indication is used with SIB 17.

Illustratively, the resource configuration of the TRS is as follows:

in an application scenario in which the terminal device enables the TRS as a pre-synchronization auxiliary signal, the network device may add six bits (Bit) of mapping information in the DCI 1_0 or DCI 2_7 format to explicitly and dynamically notify the terminal device, and the network device sends a packet number corresponding to the TRS. It should be emphasized that each packet number would correspond to multiple sets of TRS resource sets. After receiving the packet number information, the terminal device correspondingly demodulates a plurality of TRS resource sets corresponding to the number, estimates the parameters of time offset and frequency offset, and performs pre-synchronization calculation before paging time. The effective time length of the TRS depends on the configuration time in SIB17 and the period of the system message update.

In the related art, in a paging pre-synchronization scheme based on TRS assistance, a network device needs to configure multiple sets of TRS resource sets in a system message, and dynamically trigger and instruct a terminal device to detect TRS through DCI. However, due to the fact that the scheme lacks a feedback mechanism of the terminal equipment about the TRS, effective closed loop coupling of network equipment configuration-terminal equipment functions cannot be formed, configuration utilization efficiency of the network equipment for transmitting TRS resource sets for paging presynchronization can be reduced, and meanwhile detection power consumption overhead of the terminal equipment is increased to a certain extent. Overall, the TRS-assisted based paging pre-synchronization scheme in the related art has mainly the following drawbacks:

(1) The network equipment side needs to transmit a plurality of groups of TRS resource sets to ensure the reliability of paging pre-synchronization of the terminal equipment;

influence: increasing TRS resource overhead and reducing the number of idle or inactive terminal devices supportable in a cell;

reason for: the lack of effective beam management for the terminal equipment in the space domain, the lack of optimal position information judgment for the TRS in the time domain, and the use condition of the TRS resource by the terminal equipment cannot be known functionally.

(2) At the terminal device side, the detection of multiple sets of candidate TRS resource sets brings additional power consumption overhead.

Based on the above problems, the present application provides a reporting method for tracking reference signal information, which supports a terminal device to report usage or measurement conditions of TRS resources to a network device, is beneficial to the network device to more effectively configure the TRS resources, and avoids resource waste and saves power consumption overhead.

Fig. 7 is a flowchart illustrating a method for reporting tracking reference signal information according to some exemplary embodiments of the present application. Taking this method as an example, which is performed by the network device and the terminal device as shown in fig. 4, the method comprises at least part of the steps of:

step 701: the network equipment sends TRS resource configuration;

the TRS resource configuration is used to configure multiple sets of TRS resource sets. Multiple sets of TRS resource sets are used for pre-synchronization prior to receiving paging messages.

The TRS resource configuration is carried in SIB and sent to an Idle (Idle) terminal device or an Inactive (active) terminal device or a connection state terminal device.

Step 702: the terminal equipment determines a plurality of groups of TRS resource sets;

the terminal equipment interprets the SIB and determines a plurality of groups of TRS resource sets based on the received TRS resource configuration.

Step 703: the network equipment sends TRS report configuration;

the TRS reporting configuration is used for configuring TRS reporting parameters corresponding to at least one group of TRS resource sets.

The TRS reporting configuration is carried in SIB or RRC message and sent to an idle terminal device or an inactive terminal device or a connection state terminal device.

In some embodiments, the TRS reporting configuration includes at least one of:

reporting the configuration number by the TRS;

and the TRS reporting configuration is used for distinguishing the TRS reporting configuration corresponding to different TRS resource sets and/or distinguishing the TRS reporting configuration of the subsequent DCI dynamic indication.

Reporting TRS resource set (reporttrsresaroucoset);

and the TRS resource set is used for indicating the TRS resource set measured by the terminal equipment and/or indicating the terminal equipment to send corresponding TRS reporting information. Alternatively, an explicit indication mode of bit mapping is adopted. For example, the SIB configures a 64-group TRS resource set for paging pre-synchronization, and reportTRSResourceSet uses 64 bits to indicate a subset of TRS resources of the 64-group TRS resource set. Wherein the subset of TRS resources may comprise a single set of TRS resources, or a plurality of sets of TRS resources, or a 64-group set of TRS resources. For example, when the network device needs to acquire TRS reporting information of the 64-group TRS resource set complete set, or if the paging failure rate is higher than the threshold, the TRS resource subset includes 64-group TRS resource sets.

TRS reporting period (reportPeriodTYPE);

the period for indicating the terminal device to send the TRS report information comprises the following steps: at least one of periodic transmission, aperiodic transmission, and semi-persistent transmission.

When the TRS reporting period indicates periodic transmission, the terminal device periodically transmits TRS reporting information based on an integer multiple of the paging period. Optionally, the network device explicitly configures the integer value.

When the TRS report period indicates aperiodic transmission, the terminal device transmits TRS report information based on the indication of the network device.

When the TRS report period indicates semi-persistent transmission, the terminal device semi-persistently transmits TRS report information based on integer times of the paging period, and when a preset condition is met, the terminal device finishes transmitting the TRS report information. For example, if the preset condition is that the paging is successful, the terminal device finishes semi-continuously transmitting the TRS report information after the first paging is successful in the process of semi-continuously transmitting the TRS report information.

TRS reports content (reportQuantity).

In some embodiments, the TRS report includes at least one of:

acknowledgement (ACK) based on TRS measurements;

after the terminal equipment measures at least one group of TRS resource sets, TRS measurement results of the at least one group of TRS resource sets are obtained, time-frequency deviation is estimated based on the TRS measurement results, the estimated time-frequency deviation is compared with the SSB measurement results, and if the comparison results indicate that the estimated time-frequency deviation is effective, ACK is fed back.

after the terminal equipment measures at least one group of TRS resource sets, TRS measurement results of the at least one group of TRS resource sets are obtained, time-frequency deviation is estimated based on the TRS measurement results, the estimated time-frequency deviation is compared with SSB measurement results, and NACK is fed back if the comparison results indicate that the estimated time-frequency deviation is invalid.

In some embodiments, if the network device continues to receive TRS report content including NACK for a first period of time, the periodic adjustment cancels the configuration mode of TRS-assisted-based paging pre-synchronization, i.e., does not employ the TRS-assisted-based paging pre-synchronization scheme for a second period of time.

ACK based on paging result;

after measuring at least one group of TRS resource sets, the terminal equipment obtains TRS measurement results of the at least one group of TRS resource sets, estimates time-frequency deviation based on the TRS measurement results, demodulates the paging message based on the estimation results of the time-frequency deviation, and feeds back ACK if the paging message is successfully demodulated, namely the paging message is successfully received.

NACK based on paging result;

after the terminal equipment measures at least one group of TRS resource sets, TRS measurement results of the at least one group of TRS resource sets are obtained, time-frequency deviation is estimated based on the TRS measurement results, paging messages are demodulated based on the estimation results of the time-frequency deviation, and NACK is fed back if the paging messages are failed to demodulate, namely the paging messages are not successfully received.

Optimal TRS resource set;

after the terminal equipment measures at least one group of TRS resource sets, TRS measurement results of the at least one group of TRS resource sets are obtained, time-frequency deviation of each group of TRS resource sets is estimated respectively based on the TRS measurement results of the at least one group of TRS resource sets, and an optimal TRS resource set is determined based on the time-frequency deviation estimation results of the at least one group of TRS resource sets.

For example, comparing the time-frequency offset estimation result of at least one TRS resource set with the SSB measurement result, and determining the at least one TRS resource set with the time-frequency offset estimation result closest to the SSB measurement result as the optimal TRS resource set. Or demodulating the paging message based on the time-frequency deviation estimation result of at least one TRS resource set, and obtaining the optimal TRS resource set by at least one TRS resource set corresponding to the time-frequency deviation estimation result of successful demodulation of the paging message. Or, the optimal TRS resource set is understood as a TRS resource set with the highest beam overlapping degree between the beam and the terminal device in at least one group of TRS resource sets.

In some embodiments, the network device adjusts the TRS resource set configured for the terminal device according to the optimal TRS resource set in the reported content. For example, the network device screens and reduces non-optimal TRS resource sets among multiple sets of TRS resource sets, thereby reducing TRS resource overhead.

The number of optimal TRS resource sets;

after measuring at least one group of TRS resource sets, the terminal equipment obtains TRS measurement results of the at least one group of TRS resource sets, respectively estimates the time-frequency deviation of each group of TRS resource sets based on the TRS measurement results of the at least one group of TRS resource sets, and determines the quantity of the optimal TRS resource sets based on the time-frequency deviation estimation results of the at least one group of TRS resource sets; or, determining the number of the optimal TRS resource sets based on the TRS measurement capability of the terminal device.

after the terminal equipment measures at least one group of TRS resource sets, TRS measurement results of the at least one group of TRS resource sets are obtained, time-frequency deviation of each group of TRS resource sets is estimated based on the TRS measurement results of the at least one group of TRS resource sets, and TRS resource sets with the TRS measurement results superior to the first threshold value are determined based on the time-frequency deviation estimation results of the at least one group of TRS resource sets.

The first threshold is predefined, or configured by the network device, or autonomously decided by the terminal device.

similar to the number of the optimal TRS resource sets, a detailed description is omitted.

after the terminal equipment measures at least one group of TRS resource sets, TRS measurement results of the at least one group of TRS resource sets are obtained, time-frequency deviation of each group of TRS resource sets is estimated based on the TRS measurement results of the at least one group of TRS resource sets, and TRS resource sets with ranking of the TRS measurement results being positioned in the top N in the at least one group of TRS resource sets are determined based on the time-frequency deviation estimation results of the at least one group of TRS resource sets.

The effective time interval of TRS and SSB.

Since there are three period configurations of SSB period, TRS period, paging period, and at the same time, the three period configurations may correspond to different slot offsets, so that there are multiple combinations of intervals of TRS and SSB. Based on the time-frequency deviation estimation result, the terminal equipment obtains the effective interval of the TRS time slot and the SSB time slot interval, and reports the information to the network equipment for the subsequent TRS resource configuration optimization of the network equipment.

As shown in fig. 8, after the terminal device measures the TRS resource set and SSB, it is determined that the effective time interval of the TRS and SSB is 7 slots based on the time-frequency offset estimation result. That is, a TRS resource set spaced less than or equal to 7 slots from the SSB is an efficient TRS resource set for the terminal device. After the network device obtains the information, the TRS resource set with the interval of less than or equal to 7 time slots with the SSB can be configured for the terminal device, the TRS resource set with the interval of more than 7 time slots with the SSB is reduced, the waste of the TRS resources is reduced, and the effectiveness of the TRS resource configuration is improved.

Illustratively, the TRS reporting configuration corresponding to a set of TRS resource sets is as follows:

step 704: the terminal equipment determines a TRS reporting configuration set;

the terminal equipment interprets the SIB or RRC message, and determines a TRS reporting configuration set based on the received TRS reporting configuration.

Step 705: the network equipment sends a TRS measurement instruction;

the TRS measurement indication is used for indicating the terminal equipment to measure at least one group of TRS resource sets, and comprises at least one group of TRS resource set numbers and TRS reporting configuration numbers.

The at least one set of TRS resource set numbers is used to instruct the terminal device to measure the at least one set of TRS resource sets corresponding to the numbers.

The TRS report configuration number is used for indicating the terminal equipment to send TRS report information based on the TRS report configuration corresponding to the number.

The TRS measurement indication is sent carried in DCI. For example, the carrier is transmitted in DCI 1_0 or DCI 2_7.

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

Illustratively, an explicit indication field of the TRS reporting configuration is added to DCI 1_0 or DCI 2_7. Taking DCI 2_7 scrambled by PEI-RNTI as an example, TRS reporting configuration is as follows:

the TRS report configuration indicates-X bits, where the number of bits is equal to the TRS-Idle-ReportConfig in the SIB/RRC message, or log if the TRS-Idle-ReportConfig number has been configured ₂ (TRS-Idle-ReportConfig number). Otherwise the number of bits is 0.

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

Step 706: the terminal equipment determines at least one TRS resource set and TRS reporting configuration of the indication of the network equipment;

the terminal device interprets the DCI, determines at least one set of TRS resource sets and TRS reporting configurations indicated by the network device based on the received TRS measurement indication, and may also be understood as determining at least one set of TRS resource sets and TRS reporting configurations selected by the network device.

After receiving the DCI carrying the TRS report configuration number indication, the terminal equipment determines the corresponding TRS report configuration according to the higher-layer configuration inquiry in the SIB/RRC message, and further determines the subsequent TRS measurement behavior.

Step 707: the terminal equipment executes paging presynchronization;

in some embodiments, the terminal device measures at least one set of TRS resource sets based on the TRS measurement indication, obtains an estimation result of a time-frequency offset corresponding to the at least one set of TRS resource sets, and resumes synchronization with the wireless interface based on the estimation result of the time-frequency offset.

In some embodiments, the terminal device measures at least one set of TRS resources and SSB based on the TRS measurement indication, determines an estimate of time-frequency offset based on the measurement results of the at least one set of TRS resources and SSB measurements, and resumes synchronization with the wireless interface based on the estimate of time-frequency offset.

Step 708: the network equipment sends a paging message;

the network device sends a paging message to trigger a paging procedure. The paging message carries an identifier of the terminal device, which indicates that the network device initiates paging to the terminal device.

Step 709: the terminal equipment sends a paging response message;

and after receiving the paging message, the idle or inactive terminal equipment sends a paging response message for responding to the paging message from the network equipment.

Step 710: at the paging completion time, the terminal device sends TRS report information;

after the paging process is completed, the terminal device reestablishes RRC connection with the network device, and in the RRC connection process, the terminal device sends TRS report information.

The TRS report information is carried in an RRC message and sent through an uplink logical channel.

Illustratively, as shown in fig. 9, in step 901, the terminal device transmits an RRC establishment request (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 (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 (RRC Connection ReconfigurationComplete) message. The TRS report information is carried in the RRC setup request message and/or the RRC setup complete message and sent.

The TRS report information includes TRS report contents indicated in the TRS report configuration, such as ACK based on the paging result, optimal TRS resource set, the number of optimal TRS resource sets, and valid time intervals of TRSs and SSBs.

Step 711: the network equipment sends updated TRS resource configuration;

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

Exemplary, as shown in fig. 10, the network device determines a TRS measurement result or a TRS usage situation of the terminal device based on the TRS report information, including validity of the TRS, selection of an optimal TRS beam set, an optimal TRS time domain allocation scheme, and the like, screens out an optimal TRS resource set for the terminal device, adds the optimal TRS resource set in the TRS resource configuration, reduces a non-optimal TRS resource set, obtains an updated TRS resource configuration, and sends the updated TRS resource configuration to the terminal device.

The updated TRS resource configuration is sent to the terminal device in the SIB.

Step 712: the network equipment sends updated TRS report configuration;

the network device updates the TRS reporting configuration of the terminal device based on the TRS reporting information sent by the terminal device.

The updated TRS reporting configuration is configured to configure TRS reporting parameters corresponding to the updated at least one set of TRS resource sets. The content of the TRS reporting configuration refers to step 703, and the updated at least one set of TRS resource sets is the at least one set of TRS resource sets included in the TRS resource configuration updated in step 711.

The updated TRS reporting configuration is sent to the terminal device carried in SIB or RRC message.

In summary, the method provided by the present application provides a complete mechanism for configuring, measuring and feeding back a TRS resource set, and supports a terminal device to send corresponding TRS reporting information to a network device after TRS measurement, so that the network device can obtain a TRS measurement result or a service condition of the terminal device, which is favorable for forming closed loop coupling between network device configuration and feedback of the terminal device, and specifically has the following advantages:

2. The beam management performance of TRS is improved;

based on the TRS reporting information of the terminal device, the network device determines an optimal TRS resource set for the terminal device, and configures the optimal, sub-optimal TRS resource set or a subset thereof for the terminal device, thereby better and more accurately adapting to the dynamic change of the downlink channel. In the case where the TRS total resources are unchanged, the subsequent TRS resource configurations may also cover more beam directions.

3. Further saving of power consumption of the terminal equipment;

based on the TRS report information, the network device sends the TRS resource set to the terminal device more simply and more effectively, so that the terminal device can further avoid the measurement of the non-optimal TRS resource set, reduce the power consumption waste of the measurement TRS resource set and reduce the resource overhead of the measurement TRS resource set.

4. The flexibility of configuration and the comprehensiveness of the reported content are improved.

The network device can flexibly combine the TRS resource set and the TRS reporting configuration according to the measurement requirement, and can configure different TRS reporting configuration parameters for the terminal device under different scenes.
