The embodiment of the application is particularly applied to a scenario that the UE in a non-connection state (for example, idle/inactive mode) performs measurement. In 5G NR, a UE in a non-connected state performs measurement based on SSB (Synchronization Signal Block ) of a cell, and since SSB is dispersed over multiple OFDM symbols and beams, in order to meet requirements of measurement accuracy and the like, the UE in the non-connected state needs to maintain a long-time awake state in a measurement period, or needs to perform multiple wakeups, which increases power consumption of the UE.

The data transmission method provided by the application aims at based on the above scene, by configuring the CSI-RS resource for the UE in the non-connected state, the UE in the non-connected state can use the effective CSI-RS resource to measure according to the CSI-RS resource configuration, so that the wake-up time required by the UE to meet the measurement requirement can be effectively shortened, and the power consumption of the UE can be reduced.

The following describes in detail, with specific embodiments, a technical solution of an embodiment of the present application and how the technical solution of the present application solves the foregoing technical problems. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 2 is a flowchart of a data processing method according to an embodiment of the present application. As shown in fig. 2, the method specifically comprises the following steps:

step S101, when the wireless link is released, the network equipment sends CSI-RS resource allocation.

In this embodiment, when the radio link is released, the network device sends CSI-RS resource configuration to the UE, and configures a CSI-RS resource set for the UE, where the CSI-RS resource set is used for relevant measurement of the UE in a non-connected state.

Wherein, the CSI-RS resource configuration comprises configuration information of the CSI-RS resource configured for the UE.

Illustratively, the CSI-RS resource configuration includes at least one of: periodic, time-frequency location, power offset, QCL (Quasi co-located) relationship with SSB.

Step S102, the network equipment sends the CSI-RS resource.

The network equipment configures CSI-RS resources for the UE in the non-connection state, and sends corresponding CSI-RS signals to provide the CSI-RS resources for relevant strategies for the UE in the non-connection state.

Step S103, the UE in the non-connection state receives the CSI-RS resource allocation.

In this embodiment, the UE in the non-connected state may obtain CSI-RS resource configuration by receiving system parameters.

Step S104, the UE uses the effective CSI-RS resources to measure according to the CSI-RS resource allocation.

After the CSI-RS resource configuration is obtained, the UE in the non-connection state can also use the effective CSI-RS resource to measure according to the CSI-RS resource configuration, the UE does not need to wake up, the wake-up state for a long time is not required to be maintained, the wake-up time of the UE is reduced, and the power consumption of the UE is reduced.

According to the embodiment of the invention, when the wireless link is released, the network equipment transmits the CSI-RS resource configuration to configure the CSI-RS resource for the UE and transmits the CSI-RS resource, so that the UE in the non-connection state can also use the effective CSI-RS resource for measurement according to the CSI-RS resource configuration, the UE does not need to wake up frequently, the wake-up state for a long time is not required to be maintained, and the power consumption of the UE is reduced.

FIG. 3 is a schematic diagram of a transmission pattern of an SSB according to a second embodiment of the present application; fig. 4 is a flowchart of a data processing method according to a second embodiment of the present application.

In practical applications, the UE in the disconnected state may also perform measurement based on SBB.

Specifically, the network device sends SSBs according to a certain rule, and a complete SSB burst (unit) includes several SSBs in 5ms as a basic unit. The period of SSB burst may be configured to be 5ms,10ms,20ms,40ms,80ms,160ms, etc.

The SSB emission patterns in SSB burst have five classes of ABCDE, and can be divided into 8 types according to specific frequency band configuration, so as to support different numbers of maximum beam numbers.

As shown in fig. 3, the SSB emission pattern is exemplarily illustrated in fig. 3 by taking the SSB burst period as 20ms, that is, there is one SSB burst within the 20ms period. Fig. 3 shows SCS (Sub-carrier spacing), frequency band, etc. information corresponding to different transmission patterns.

A maximum number of 4 or 8 or 64 beams can be transmitted every 5ms in different scenarios. Each SSB occupies 4 consecutive OFDM symbols. The UE in the non-connected state may perform measurement of SS-RSRP (Synchronization Signal Reference Signal Received Power ) and SS-RSRQ (Synchronization Signal Reference Signal Received Quality, synchronization signal reference signal received quality) according to SSS (Secondary Synchronization Signal ) signals in the SSB. Wherein the measurement time is determined by SMTC (SSB-based RRM Measurement Timing Configuration, SSB based RRM measurement timing configuration) parameters.

The specific measurement details can be autonomously implemented by the UE, and only the accuracy in the test scenario meeting the protocol requirements is needed, which is not specifically limited here.

According to 38.101 the UE needs to select the result corresponding to the optimal beam of the multiple measurements according to EIS (Effective Isotropic Sensitivity, effective radiation reception sensitivity) criteria, i.e. when there are multiple downlink and uplink beams.

Since the transmission symbol positions of SSBs are fixed, the UE needs to make multiple measurements over a large number of slots within the SMTC window when making measurements, especially when the number of transmit and receive beams is large.

Illustratively, SMTC parameters include the following 3 parameters: period, offset within period, and duration. For example, the configuration of SMTC may be as follows:

periodicity::{SF5,SF10,SF20,SF40,SF80,SF160}

Offset::{0-periodicity-1}

Duration:{sf1,sf2,sf3,sf4,sf5}

in order to reduce power consumption and wake-up time of the UE, it is necessary to reduce measurement time (duration) of the UE as much as possible and increase period (periodicity), but this may lead to an increase in measurement error, for example, the UE position has a larger movement in this period, so that mobility process cannot be timely perceived and performed, thereby affecting system performance.

Because the SSB signal is fixed and is not suitable for increasing the density for UE measurement, in this embodiment, measurement of CSI-RS by the UE in a non-connected state is introduced, and in addition, measurement of CSI-RS in the measurement result can be equivalent to SS-related measurement quantity by using QCL relationship, so as to support measurement of measurement quantity meeting the accuracy requirement in a short time by the UE.

As shown in fig. 4, the specific steps of the data processing method in this embodiment are as follows:

step S201, when the radio link is released, the network device sends a radio link release message containing CSI-RS resource configuration.

The CSI-RS resource set is configured for the UE and comprises one or more groups of CSI-RS resources, and the CSI-RS resource configuration comprises configuration information of the CSI-RS resources configured for the UE. The CSI-RS resource configuration includes at least one of the following configuration information for each CSI-RS resource: the period, time-frequency position, power offset, QCL relationship with SSB.

For example, the configuration of CSI-RS resources may be implemented as shown in fig. 5.

Optionally, the configuration information of the CSI-RS resource may further include: scrambling code information of CSI-RS resources.

In addition, the CSI-RS resource configuration includes at least one of:

the CSI-RS measurement resource allocation of the cell and the CSI-RS measurement resource allocation of the neighbor cell.

The present cell refers to a current serving cell of the UE.

Optionally, the network device may configure CSI-RS measurement resources of the cell configured for the UE, and the UE performs related measurement of the cell based on the CSI-RS measurement resources of the cell.

Optionally, the network device may further configure CSI-RS measurement resources of the neighboring cell configured for the UE, where the UE performs related measurement of the neighboring cell based on the CSI-RS measurement resources of the neighboring cell.

Optionally, the network device may also configure the CSI-RS measurement resource configuration of the own cell and the CSI-RS measurement resource configuration of the neighboring cell for the UE at the same time, where the UE performs related measurements of the own cell and the neighboring cell based on the CSI-RS measurement resource configuration of the own cell and the CSI-RS measurement resource configuration of the neighboring cell, respectively.

In addition, when the network equipment configures the CSI-RS resource for the UE, the dislocation of the configured CSI-RS and SSB symbols can be considered, so that efficient measurement is realized.

For example, for SSB configuration with a transmit pattern D as shown in fig. 6, a maximum of 64 beams are contained within 5 ms. Where the first 2 SSBs may be represented by the specific symbols in fig. 7, the top row of numbers (0-27) in fig. 7 represents the number of OFDM symbols, and for 120 scs, each 1ms contains 14×8=112 symbols. Wherein the 4 boxes from the beginning of the OFDM symbols numbered 4,8, 16 and 20 in the second row above represent the 4 symbols occupied by one SSB. The 4 SSBs in fig. 7 correspond to beam index 0/1/2/3, respectively. The CSI-RS may support a variety of symbol position configurations, such as the network device may configure the UE with 4 sets of CSI-RS (e.g., may be TRS (tracking reference signal, tracking reference signal)) 3/4/5/6, etc. The base station uses a different beam than beam index 0/1/2/3 on symbol 0/1/2/3, such as index32/32/33/33, and symbol 14/15 uses beam index34. Thus, only 4-beam measurements were originally measured in 1ms, 3-beam measurements can be additionally provided based on CSI-RS, and SSBs with the same beam number on the following symbol are not measured. Similarly, the latter 1ms also uses a similar method to make measurements of other beams. The UE can measure all beams of the base station in a shorter time, so that the total wake-up time is shortened, and the power consumption of the terminal is effectively reduced.

Step S202, the network equipment sends the CSI-RS resources according to the CSI-RS resource configuration.

In this embodiment, the network device configures CSI-RS resources for the UE, and sends CSI-RS resources according to the CSI-RS resource configuration, for the UE to measure.

For example, the network device may periodically transmit CSI-RS resources according to the CSI-RS resource configuration.

After the network device sends the CSI-RS resource configuration, the CSI-RS resource may be periodically sent according to the CSI-RS resource configuration. That is, this step is performed after step S201, which is performed in parallel with steps S203 to S204.

Step S203, the UE in the non-connected state receives a radio link release message containing CSI-RS resource configuration.

The UE in the non-connected state receives the radio link release message containing the CSI-RS resource configuration, and may acquire the CSI-RS resource configuration in the radio link release message.

Step S204, the UE uses the effective CSI-RS resources to measure according to the CSI-RS resource allocation.

In one possible implementation manner of this embodiment, it is considered that the network device configures CSI-RS resources for the UE in a connected state, and transmits CSI-RS signals for measurement by the UE in the connected state. Therefore, the network equipment can configure the UE in the non-connection state to measure the CSI-RS resources sent to the UE in other connection states in the cell, so that the measurement of the UE in the non-connection state based on the CSI-RS is realized, the total wake-up time of the UE is reduced, and the energy consumption of the UE is reduced.

Since the CSI-RS is configured by the network device according to other connected UEs, once the connected UE releases, it is possible that the corresponding CSI-RS resources are also released.

In one possible implementation, the effective CSI-RS resources may be determined according to the following manner:

the network equipment transmits DCI (Downlink Control Information ) containing the validity information of the CSI-RS resource; and the UE receives the DCI and determines effective CSI-RS resources according to the DCI.

The validity information of the CSI-RS resource may be a validity period of the CSI-RS resource.

For example, the UE in the non-connected state may periodically receive paging (paging) information, and the network device may transmit DCI in a paging cycle to enable the UE in the non-connected state to receive the DCI. The DCI includes validity of CSI-RS resources for UE measurement in a non-connected state in a current paging cycle.

Optionally, the DCI including the validity information of the CSI-RS resource may be scrambled using a specific scrambling code, so that only the UE having a descrambling sequence corresponding to the specific scrambling code may decode using the corresponding descrambling sequence to obtain the validity information of the CSI-RS resource in the DCI, and other UEs cannot obtain the validity information of the CSI-RS resource in the DCI.

Alternatively, the DCI may indicate the validity of the relevant CSI-RS resource or CSI-RS resource set using a bit stream.

For example, if 32 CSI-RS resources are configured for a UE in a non-connected state, then 32 bits (bits) may be used in the DCI to identify the validity of these resources in the current period, where each bit corresponds to a resource index, bit 1 indicates that the UE may use the resource for measurement, and bit 0 indicates that the resource is not available in the current period.

In addition, when the network device indicates the validity of the CSI-RS resource through the DCI, and when the corresponding wireless link is released to cause the invalid CSI-RS, the network device needs to continuously send the CSI-RS according to the valid period range, so that the valid CSI-RS exists in the valid period range of the DCI.

the UE uses the configured CSI-RS resources to measure according to the configuration of the CSI-RS resources; and determining effective CSI-RS resources according to the measurement result.

Further, the UE determines an effective CSI-RS resource according to the measurement result, including:

the UE compares the measurement result of the CSI-RS resource with the measurement result on the SSB resource to obtain the difference between the measurement result and the measurement result, and preferably, the SSB resource and the CSI-RS resource have the same QCL; if the difference is smaller than or equal to the preset threshold, the CSI-RS resource is an effective resource, and the measurement result of the CSI-RS resource is an effective measurement result of using the effective CSI-RS resource for measurement.

The preset threshold may be configured according to an actual application scenario, which is not specifically limited herein.

In this embodiment, the UE may autonomously detect the validity of CSI-RS resources. The UE compares the correlation measured value based on the CSI-RS with the correlation measured value based on the SSB, and if the deviation of the correlation measured value based on the CSI-RS and the correlation measured value based on the SSB is within a preset threshold, the UE considers that the CSI-RS resource is effective and the measurement result based on the CSI-RS is effective; and if the deviation of the two is larger than a preset threshold, the CSI-RS resource is considered invalid, and the measurement result based on the CSI-RS is considered invalid.

detecting period configuration by the network equipment; and the UE receives the detection period configuration, and determines the CSI-RS resource in the detection period as an effective resource according to the detection period configuration.

The detection period configuration may be carried in a radio link release message, for example.

In this embodiment, the network device may also configure a separate detection period, according to which the UE performs relevant measurements based on CSI-RS resources.

Step S205, the UE reports the measurement result.

Step S206, the network equipment receives the measurement result.

Step S207, the network equipment performs mobility processing according to the measurement result.

Wherein the measurement comprises at least one of:

SS-RSRP (Synchronization Signal Reference Signal Received Power ), SS-RSRQ (Synchronization Signal Reference Signal Received Quality, synchronization signal reference signal received quality), CSI-RSRP (Channel State Information Reference Signal Received Power ), CSI-RSRQ (Channel State Information Reference Signal Received Quality, channel state information reference signal received quality).

In one possible implementation, after the UE performs measurement, the UE may directly report the CSI-RS measurement result obtained based on the CSI-RS measurement. And the network equipment performs mobility processing according to the CSI-RS measurement result.

In another possible embodiment, after obtaining the CSI-RS measurement result obtained based on the CSI-RS measurement, the UE may convert the CSI-RS measurement result into an equivalent SS measurement result, and report the converted equivalent SS measurement result. And the network equipment performs mobility processing according to the equivalent SS measurement result.

For example, the power offset of the CSI-RS is configured in the CSI-RS resource, that is, the difference between the power of the CSI-RS signal transmitted by the network device and the SS signal. Assuming that the power offset of the CSI-RS is-3 db, the power of the CSI-RS signal transmitted by the network equipment is 3db lower than that of the SS signal, and then the equivalent SS-RSRP value is the measured CSI-RSRP+3db. In addition, other parameter values may be configured to perform similar conversion on other measured values, which is not listed here.

The power offset for configuring the CSI-RS in the CSI-RS resource may be any one of the following: 3db,0db,3db,6db, the present embodiment is not particularly limited here.

In another possible embodiment, after the UE performs measurement, the UE may directly report the CSI-RS measurement result obtained based on the CSI-RS measurement. The network equipment converts the received CSI-RS measurement result into an equivalent SS measurement result, and performs mobility processing according to the converted equivalent SS measurement result.

In another possible embodiment, after the UE performs measurement, the UE may directly convert the CSI-RS measurement result obtained based on the CSI-RS measurement into an equivalent SS measurement result; and carrying out differentiated reporting on the equivalent SS measurement result and the SS measurement result obtained based on the SSB measurement. And the network equipment performs mobility processing according to the equivalent SS measurement result or the SS measurement result obtained based on the SSB measurement.

In another possible embodiment, after the UE performs measurement, the UE may report the CSI-RS measurement result and the SS measurement result obtained based on SSB measurement directly after the UE performs the CSI-RS measurement; the network equipment converts the received CSI-RS measurement result into an equivalent SS measurement result, and respectively carries out mobility processing according to the equivalent SS measurement result or the SS measurement result obtained based on SSB measurement.

In this embodiment, the network device may further perform mobility processing according to at least one of CSI-RS measurement results obtained based on CSI-RS measurement, equivalent SS measurement results converted from CSI-RS measurement results, and SS measurement results obtained based on SSB measurement, which is not specifically limited herein.

The mobility processing performed by the network device may include a cell selection, a cell reselection, and the like, which is not specifically limited herein.

In addition, in this embodiment, taking measurement of a serving cell by a UE in a non-connected state as an example, an exemplary description is made, and a method for performing measurement of a neighboring cell (non-serving cell) is similar, and a measurement object may be extended to the neighboring cell, which is not described herein.

According to the embodiment of the invention, the network equipment configures the CSI-RS resource for the UE, periodically transmits the CSI-RS resource according to the CSI-RS resource configuration, and uses the effective CSI-RS resource to measure according to the CSI-RS resource configuration, and can convert the CSI-RS measurement result obtained based on the CSI-RS measurement into the equivalent SS measurement result, and the network equipment can perform mobility processing according to one or more of the CSI-RS measurement result, the equivalent SS measurement result and the SS measurement result obtained based on the SSB measurement, so that the UE does not need to keep a long-time awakening state, the awakening time of the UE is reduced, and the power consumption of the UE is reduced.
