[0046] The embodiments of the present application are specifically applied to the scenario of measuring UE in a non-connected state (e.g., idle / inactive mode). In 5G NR, a UE in a non-connected state performs measurements based on the SSB of the cell. Since the SSB is scattered over multiple OFDM symbols and beams, in order to meet the requirements of measurement accuracy, the UE in a non-connected state needs to remain awake for a long time during the measurement period, or needs to be awakened multiple times, which increases the power consumption of the UE.

[0047] The data transmission method provided in the present application aims to configure CSI-RS resources for UE in a non-connected state based on the above scenario. The UE in a non-connected state can use effective CSI-RS resources for measurement according to the CSI-RS resource configuration, which can effectively shorten the wake-up time required for the UE to meet the measurement requirements and reduce the power consumption of the UE.

[0048] The following specific embodiments are used to describe in detail the technical solutions of the embodiments of the present application and how the technical solutions of the present application solve the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0049] Figure 2 This is a flow chart of a data processing method provided in Example 1 of this application. Figure 2 As shown, the specific steps of this method are as follows:

[0050] Step S101: When the wireless link is released, the network device sends a CSI-RS resource configuration.

[0051] In this embodiment, when the radio link is released, the network device sends a CSI-RS resource configuration to the UE, and configures a CSI-RS resource set for the UE. The CSI-RS resource set is used for related measurements of the UE in a non-connected state.

[0052] The CSI-RS resource configuration includes configuration information of the CSI-RS resources configured for the UE.

[0053] Exemplarily, the CSI-RS resource configuration includes at least one of the following: period, time-frequency position, power offset, and QCL (Quasi co-located) relationship with SSB.

[0054] Step S102: The network device sends CSI-RS resources.

[0055] The network device configures CSI-RS resources for the UE in the non-connected state and sends a corresponding CSI-RS signal to provide the UE in the non-connected state with CSI-RS resources for implementing relevant strategies.

[0056] Step S103: The UE in the non-connected state receives CSI-RS resource configuration.

[0057] In this embodiment, the UE in the non-connected state can obtain the CSI-RS resource configuration by receiving system parameters.

[0058] Step S104: The UE uses valid CSI-RS resources for measurement according to the CSI-RS resource configuration.

[0059] After obtaining the CSI-RS resource configuration, a UE in a non-connected state can also use valid CSI-RS resources for measurement according to the CSI-RS resource configuration. The UE does not need to wake up or stay awake for a long time, which reduces the UE's wake-up time and the UE's power consumption.

[0060] In the embodiment of the present application, when the wireless link is released, the network device sends a CSI-RS resource configuration to configure the CSI-RS resource for the UE, and sends the CSI-RS resource, so that the UE in a non-connected state can also use the effective CSI-RS resource for measurement according to the CSI-RS resource configuration. The UE does not need to be frequently awakened or stay awake for a long time, thereby reducing the power consumption of the UE.

[0061] Figure 3 A schematic diagram of the SSB transmission pattern provided in Embodiment 2 of the present application; Figure 4 A flow chart of a data processing method provided in Example 2 of the present application.

[0062] In practical applications, a UE in a non-connected state may also perform measurements based on the SBB.

[0063] Specifically, network devices send SSB according to certain rules. A complete SSB burst (unit) is based on 5ms as the basic unit and contains several SSBs. The period of SSB burst can be configured to 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, etc.

[0064] There are five categories of SSB transmission patterns in SSB burst: A, B, C, and D. According to the specific frequency band configuration, they can be divided into 8 types, supporting different maximum numbers of beams.

[0065] like Figure 3 As shown, Figure 3 In the figure, the transmission pattern of SSB is exemplarily described by taking the period of SSB burst as 20ms, that is, there is one SSBburst in a 20ms period as an example. Figure 3 The information including SCS (Sub-carrier spacing) and frequency band corresponding to different transmission patterns is shown.

[0066] In different scenarios, a maximum of 4, 8 or 64 beams can be sent every 5ms. Each SSB occupies 4 consecutive OFDM symbols. A UE in a non-connected state can measure SS-RSRP (Synchronization Signal Reference Signal Received Power) and SS-RSRQ (Synchronization Signal Reference Signal Received Quality) based on the SSS (Secondary Synchronization Signal) signal in the SSB. Among them, the measurement time is determined by the SMTC (SSB-based RRM Measurement Timing Configuration) parameter.

[0067] The specific measurement details can be implemented by the UE independently, and only need to meet the accuracy in the test scenario required by the protocol, and this embodiment is not specifically limited here.

[0068] According to 38.101, the measurement is based on the EIS (Effective Isotropic Sensitivity) criterion, that is, when there are multiple downlink beams and uplink beams, the UE needs to select the result corresponding to the optimal beam from multiple measurement results.

[0069] Since the transmission symbol position of SSB is fixed, the UE needs to perform multiple measurements on more slots within the SMTC window when performing measurements, especially when there are a large number of transmit and receive beams.

[0070] Exemplarily, the SMTC parameters include the following three parameters: period, offset within period and duration. For example, the configuration of SMTC can be as follows:

[0071] periodicity::{SF5,SF10,SF20,SF40,SF80,SF160}

[0072] Offset::{0-periodicity-1}

[0073] Duration:{sf1,sf2,sf3,sf4,sf5}

[0074] In order to reduce power consumption and shorten the UE wake-up time, it is necessary to minimize the UE measurement time (duration) and increase the period (periodicity). However, this will lead to an increase in measurement errors. For example, if the UE position moves significantly during this period, it will not be able to perceive and perform the mobility process in time, thus affecting system performance.

[0075] Since the SSB signal is fixed and is not suitable for increasing the density for UE measurement, in this embodiment, the measurement of CSI-RS by the UE in a non-connected state is introduced. In addition, the CSI-RS measurement in the measurement result can be equivalent to the SS-related measurement quantity using the QCL relationship, thereby supporting the UE to obtain the measurement quantity that meets the accuracy requirements in a shorter time.

[0076] like Figure 4 As shown, the specific steps of the data processing method in this embodiment are as follows:

[0077] Step S201: When a radio link is released, the network device sends a radio link release message including CSI-RS resource configuration.

[0078] In this embodiment, when the radio link is released, the network device sends a CSI-RS resource configuration to the UE, and configures a CSI-RS resource set for the UE. The CSI-RS resource set is used for related measurements of the UE in a non-connected state.

[0079] The CSI-RS resource set configured for the UE includes one or more groups of CSI-RS resources, and the CSI-RS resource configuration includes 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: period, time-frequency position, power offset, and QCL relationship with SSB.

[0080] For example, the configuration of CSI-RS resources can be as follows: Figure 5 The method shown is implemented.

[0081] Optionally, the configuration information of the CSI-RS resource may further include: scrambling code information of the CSI-RS resource.

[0082] In addition, the CSI-RS resource configuration includes at least one of the following:

[0083] The CSI-RS measurement resource configuration of this cell and the CSI-RS measurement resource configuration of the neighboring cell.

[0084] The current cell refers to the current serving cell of the UE.

[0085] Optionally, the network device may configure a CSI-RS measurement resource configuration of the cell for the UE, and the UE performs relevant measurements of the cell based on the CSI-RS measurement resource configuration of the cell.

[0086] Optionally, the network device may further configure a CSI-RS measurement resource configuration of a neighboring cell for the UE, and the UE performs related measurements of the neighboring cell based on the CSI-RS measurement resource configuration of the neighboring cell.

[0087] Optionally, the network device may also simultaneously configure the CSI-RS measurement resource configuration of the current cell and the CSI-RS measurement resource configuration of the neighboring cell for the UE, and the UE performs relevant measurements of the current cell and the neighboring cell based on the CSI-RS measurement resource configuration of the current cell and the CSI-RS measurement resource configuration of the neighboring cell, respectively.

[0088] In addition, when the network device configures CSI-RS resources for the UE, it can consider configuring the misalignment of CSI-RS and SSB symbols to achieve efficient measurement.

[0089] For example, Figure 6 The transmission pattern shown is the SSB configuration of D, which contains a maximum of 64 beams within 5ms. The specific symbols of the first two SSBs can be as follows Figure 7 As shown, Figure 7 The top row of numbers (0-27) indicates the number of OFDM symbols. For 120k SCS, each 1ms contains 14*8=112 symbols. The 4 grids starting from the OFDM symbols numbered 4, 8, 16 and 20 in the second row from the top indicate the 4 symbols occupied by one SSB. Figure 7 The 4 SSBs correspond to beam index 0 / 1 / 2 / 3 respectively. CSI-RS can support multiple symbol position configurations. For example, the network equipment can configure 4 groups of CSI-RS such as 3 / 4 / 5 / 6 for the UE (for example, it can be TRS (tracking reference signal)). The base station uses a beam different from beam index 0 / 1 / 2 / 3 on symbols 0 / 1 / 2 / 3, such as index 32 / 32 / 33 / 33, and symbol 14 / 15 uses beam index 34. In this way, the measurement of 4 beams that could originally be measured within 1ms can now be provided based on CSI-RS. The SSBs with the same beam number on the subsequent symbols do not need to be measured. Similarly, similar methods are used to measure other beams in the following 1ms. The UE can measure all beams of the base station in a shorter time, thereby shortening the total wake-up time and effectively reducing terminal power consumption.

[0090] Step S202: The network device sends CSI-RS resources according to the CSI-RS resource configuration.

[0091] In this embodiment, the network device configures CSI-RS resources for the UE, and sends the CSI-RS resources according to the CSI-RS resource configuration for the UE to perform measurement.

[0092] Exemplarily, the network device may periodically send CSI-RS resources according to the CSI-RS resource configuration.

[0093] After the network device sends the CSI-RS resource configuration, it can periodically send the CSI-RS resource according to the CSI-RS resource configuration. That is, this step is performed after step S201, and this step is performed in parallel with steps S203-S204.

[0094] Step S203: The UE in the non-connected state receives a radio link release message including CSI-RS resource configuration.

[0095] The UE in the non-connected state receives the radio link release message including the CSI-RS resource configuration, and can obtain the CSI-RS resource configuration in the radio link release message.

[0096] Step S204: The UE uses valid CSI-RS resources for measurement according to the CSI-RS resource configuration.

[0097] In a possible implementation of this embodiment, considering that the network device configures CSI-RS resources for the connected UE and transmits CSI-RS signals for the connected UE to measure, the network device can configure the non-connected UE to measure the CSI-RS resources sent to other connected UEs in the cell, thereby implementing CSI-RS-based measurement for the non-connected UE, thereby reducing the total wake-up time of the UE and reducing the energy consumption of the UE.

[0098] Since CSI-RS is configured by the network device according to other connected UEs, once the connected UE is released, the corresponding CSI-RS resources may also be released. In this embodiment, when measuring, the UE in the non-connected state needs to first detect the validity of the CSI-RS resources in the resource pool, and then use the valid CSI-RS resources for measurement.

[0099] In a possible implementation manner, the effective CSI-RS resource may be determined in the following manner:

[0100] The network device sends DCI (Downlink Control Information) containing validity information of the CSI-RS resources; the UE receives the DCI and determines the valid CSI-RS resources according to the DCI.

[0101] The validity information of the CSI-RS resource may be a valid period of the CSI-RS resource.

[0102] For example, a UE in a non-connected state may receive paging information periodically, and a network device may send DCI in a paging cycle so that the UE in a non-connected state can receive the DCI. The DCI includes the validity of CSI-RS resources measured by the UE in a non-connected state in the current paging cycle.

[0103] Optionally, the DCI containing the validity information of the CSI-RS resources can be scrambled using a specific scrambling code, so that only the UE that has the descrambling sequence corresponding to the specific scrambling code can use the corresponding descrambling sequence for decoding to obtain the validity information of the CSI-RS resources in the DCI, while other UEs cannot obtain the validity information of the CSI-RS resources in the DCI.

[0104] Optionally, the DCI may indicate the validity of a related CSI-RS resource or a CSI-RS resource set in a bit stream manner.

[0105] For example, if 32 CSI-RS resources are configured for a UE in a non-connected state, 32 bits may be used in the DCI to identify the validity of these resources in the current cycle, where each bit corresponds to a resource index, and bit 1 indicates that the UE can use the resource for measurement, and bit 0 indicates that the resource is not available in the current cycle.

[0106] In addition, when the network device indicates the validity of CSI-RS resources through DCI, when the corresponding wireless link is released and the CSI-RS becomes invalid, the network device needs to continue to send CSI-RS according to the valid period range so that there is a valid CSI-RS within the valid period range of DCI.

[0107] In a possible implementation manner, the effective CSI-RS resource may be determined in the following manner:

[0108] The UE performs measurement using the configured CSI-RS resources according to the CSI-RS resource configuration and determines the effective CSI-RS resources according to the measurement result.

[0109] Furthermore, the UE determines a valid CSI-RS resource according to the measurement result, including:

[0110] 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 two. Preferably, the SSB resource and the CSI-RS resource have the same QCL; if the difference is less than or equal to the preset threshold, the CSI-RS resource is a valid resource, and the measurement result of the CSI-RS resource is a valid measurement result measured using the valid CSI-RS resource.

[0111] The preset threshold may be configured according to actual application scenarios, and is not specifically limited in this embodiment.

[0112] In this implementation, the UE can autonomously detect the validity of the CSI-RS resource. The UE compares the size of the relevant measurement value based on the CSI-RS with the relevant measurement value based on the SSB. If the deviation between the two is within the preset threshold, the CSI-RS resource is considered to be valid and the measurement result based on the CSI-RS is valid; if the deviation between the two is greater than the preset threshold, the CSI-RS resource is considered to be invalid and the measurement result based on the CSI-RS is invalid.

[0113] In a possible implementation manner, the effective CSI-RS resource may be determined in the following manner:

[0114] The network device detects the period configuration; the UE receives the detection period configuration, and determines that the CSI-RS resources within the detection period are valid resources according to the detection period configuration.

[0115] Exemplarily, the detection period configuration may be carried in a radio link release message.

[0116] In this implementation, the network device may also be configured with a separate detection period, and the UE performs relevant measurements based on CSI-RS resources according to the detection period.

[0117] Step S205: The UE reports the measurement result.

[0118] Step S206: The network device receives the measurement result.

[0119] Step S207: The network device performs mobility processing according to the measurement result.

[0120] The measurement result includes at least one of the following:

[0121] SS-RSRP (Synchronization Signal Reference Signal Received Power), SS-RSRQ (Synchronization Signal Reference Signal ReceivedQuality), CSI-RSRP (Channel State InformationReference Signal Received Power), CSI-RSRQ (Channel State Information Reference Signal Received Quality).

[0122] In a possible implementation, after the UE performs measurement, the UE may directly report the CSI-RS measurement result obtained based on the CSI-RS measurement. The network device performs mobility processing according to the CSI-RS measurement result.

[0123] In another possible implementation, after obtaining the CSI-RS measurement result 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. The network device performs mobility processing according to the equivalent SS measurement result.

[0124] For example, the power bias of CSI-RS is configured in the CSI-RS resource, that is, the difference in power of the CSI-RS signal transmitted by the network device relative to the SS signal. Assuming that the power bias of CSI-RS is -3db, the power of the CSI-RS signal transmitted by the network device is 3db lower than that of the SS signal, then the equivalent SS-RSRP value is the measured CSI-RSRP+3db. In addition, other measured values ​​can be converted similarly by configuring other parameter values, which are not listed one by one in this embodiment.

[0125] The power offset of the CSI-RS configured in the CSI-RS resource may be any one of the following: -3db, 0db, 3db, 6db, which is not specifically limited in this embodiment.

[0126] In another possible implementation, after the UE performs the measurement, the UE may directly report the CSI-RS measurement result obtained based on the CSI-RS measurement. The network device 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.

[0127] In another possible implementation, after the UE performs measurement, the UE may directly convert the CSI-RS measurement result obtained based on the CSI-RS measurement, and the UE may convert the CSI-RS measurement result into an equivalent SS measurement result; the equivalent SS measurement result and the SS measurement result obtained based on the SSB measurement are reported separately. The network device performs mobility processing according to the equivalent SS measurement result or the SS measurement result obtained based on the SSB measurement.

[0128] In another 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 SS measurement result obtained based on the SSB measurement; the network device converts the received CSI-RS measurement result into an equivalent SS measurement result, and performs mobility processing according to the equivalent SS measurement result or the SS measurement result obtained based on the SSB measurement.

[0129] In this embodiment, the network device may also perform mobility processing based on at least one of the CSI-RS measurement results obtained based on the CSI-RS measurement, the equivalent SS measurement results converted from the CSI-RS measurement results, and the SS measurement results obtained based on the SSB measurement. This embodiment is not specifically limited here.

[0130] The mobility processing performed by the network device may include processes such as cell selection and cell reselection, which are not specifically limited in this embodiment.

[0131] In addition, this embodiment takes the measurement of the serving cell by a UE in a non-connected state as an example for exemplary description.
