Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a data transmission method, device, and storage medium. Background Art

[0002] Small Data Transmission (SDT) refers to a technology in which a User Equipment (UE) uses pre-configured resources (Configured Grant, CG) or random access resources (Random Access, RA) to transmit small data packets when in the Radio Resource Control (RRC) inactive state (RRC_INACTIVE state).

[0003] When there is a small data packet to be sent, the UE will select the SDT mode or the non-SDT mode according to the RSRP (Reference Signal Receiving Power) threshold and / or data volume threshold configured by the network device. Once the SDT mode is selected, the user equipment in the RRC_INACTIVE state can avoid changing the RRC state and save signaling overhead. After selecting SDT, if there is no specific indication of which carrier to select, the carrier can be selected according to the RSRP threshold broadcast by the network device; further, if the CG criterion is met, the CG resource is selected for SDT transmission; if the CG criterion is not met, the two-step random access process (2-step RA) or the four-step random access process (4-step RA) type is selected for SDT transmission according to the RA criterion.

[0004] In the prior art, which specific transmission mode is adopted in the above small data transmission process depends on the SDT configuration information configured by the network device for selection. However, due to possible changes in the network environment between the terminal device and the network device, it may not be possible to select the SDT mode, and only the non-SDT mode can be selected, thereby increasing the signaling overhead in the small data transmission process.

[0191] In this application, the term "and / or" describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the front and back associated objects.

[0192] In the embodiments of this application, the term "multiple" means two or more, and other quantifiers are similar.

[0193] The UE is in the Radio Resource Control (RRC) inactive state (RRC_INACTIVE). When there are small data packets to be sent, if it enters the RRC_CONNECTED state for sending, the signaling overhead will increase. Therefore, for small data packets, in order to avoid increasing the signaling overhead, the UE can send small data packets without entering the RRC_CONNECTED state, but through pre-configured resources (CG resources) or random access resources (RA resources). That is, small data transmission (SDT) refers to the UE using CG resources or RA resources to transmit small data packets in the RRC_INACTIVE state.

[0194] Specifically, for the data to be transmitted, the UE will select the SDT or non-SDT process according to the RSRP threshold and / or data volume threshold configured by the network device. After selecting the SDT process, if there is no specific indication of which carrier to select, the carrier can be selected according to the RSRP threshold broadcast by the network device. Further, if the CG criterion is met, the CG resource is selected for SDT transmission, where the SSB (Synchronization Signal Block) and / or the TA (Timing Advance) effective TA timer are selected according to the RSRP threshold associated with the CG SSB; if the CG criterion is not met, the 2-step RA or 4-step RA type is selected for SDT transmission according to the RA criterion.

[0195] In the prior art, the specific transmission method adopted in the above small data transmission process needs to rely on the SDT configuration information configured by the network device for selection. However, the network environment between the terminal device and the network device may change. For example, the network signal quality, CG resources, RA resource status, etc. between the terminal device and the network device may change, resulting in the inability to select the SDT method when selecting the target transmission method according to the SDT configuration information configured by the network device, and only the non-SDT method can be selected. In this case, it may be necessary to change the RRC state, increasing the signaling overhead in the small data transmission process; in another case, it may also be possible to select the SDT method when selecting the target transmission method according to the SDT configuration information configured by the network device, but the current network environment such as signal quality, CG resources, and RA resource status may no longer be applicable to the SDT method, resulting in the inability to transmit data smoothly.

[0196] Therefore, due to the SDT configuration information based on the network device, there is a problem that the determined transmission method is unreasonable and cannot reasonably guide the UE to adopt a suitable data transmission method for data transmission, resulting in problems such as energy consumption or low data transmission efficiency.

[0197] In view of the above technical problems, in the embodiments of the present application, for the data to be transmitted, according to the SDT configuration information, the target transmission method of the data to be transmitted is determined, where the SDT configuration information is configured by the network device; the relevant information generated during the process of determining the target transmission method for the data to be transmitted is sent to the network device, and the relevant information is used to optimize the SDT configuration information, so that the network device can dynamically optimize the SDT configuration information according to the relevant information, thereby more reasonably configuring and optimizing the small data transmission process, and enabling the UE to determine a reasonable transmission method based on the optimized SDT configuration information.

[0198] The embodiments of the present application are applied to, such as Figure 1The application scenario shown includes a terminal device 101 and a network device 102. The network device 102 can send small data transmission (SDT) configuration information to the terminal.

[0202] Embodiments of the present application provide a data transmission method, device, storage medium, and program product. Among them, the method, device, storage medium, and program product are based on the same inventive concept. Since the principles for solving problems are similar, their embodiments can be referred to each other, and repeated parts will not be elaborated.

[0203] Embodiment 1

[0204] Figure 2 is a flowchart of the data transmission method provided in this embodiment. As Figure 2 shown, this embodiment provides a data transmission method, and the execution entity is a terminal device UE. The specific steps of this data transmission method are as follows:

[0205] S201. For the data to be transmitted, determine the target transmission mode of the data to be transmitted according to the SDT configuration information, where the SDT configuration information is configured by a network device.

[0206] In this embodiment, the network device may send the SDT configuration information to the terminal device. The SDT configuration information may include configuration parameters for guiding the UE in the data transmission process, including but not limited to various preset thresholds involved in the UE's determination of the target transmission mode, such as preset signal quality thresholds at each stage, the duration threshold of the timing advance timer TAT, the preset number threshold corresponding to the SDT transmission times, an instruction for specifying the target transmission mode, an instruction for converting the transmission mode, and so on, one or more of them.

[0207] In this embodiment, when the UE is currently in the RRC_INACTIVE state, the target transmission mode of the data to be transmitted can be determined according to the SDT configuration information. The target transmission mode may include but is not limited to non-SDT transmission mode and SDT transmission mode. The SDT transmission mode may include but is not limited to SDT transmission mode based on pre-configured resources or SDT transmission mode based on RA resources. The non-SDT transmission mode includes but is not limited to performing an RRC Resume process (RRC recovery process).

[0208] Optionally, when determining the target transmission mode of the data to be transmitted according to the SDT configuration information, it may specifically include the following steps:

[0209] 1) Determine whether to select the SDT transmission mode.

[0210] Optionally, it may be determined whether the data volume of the data to be transmitted is less than a preset data volume threshold, and / or whether the first measurement value of the signal quality of the reference signal is not less than the first preset signal quality threshold X1;

[0211] If the data volume of the data to be transmitted is greater than the preset data volume threshold, and / or the first measured value of the signal quality of the reference signal is less than the first preset signal quality threshold X1, the target transmission mode can be determined to be a non-SDT transmission mode, and then the data to be transmitted is transmitted to the network device in the non-SDT transmission mode;

[0212] If the data volume of the data to be transmitted is not greater than the preset data volume threshold, and / or the first measured value of the signal quality of the reference signal is not less than the corresponding first preset signal quality threshold X1, it can be preliminarily determined that the SDT transmission mode needs to be adopted, and whether to specifically adopt the SDT transmission mode based on preconfigured resources or the SDT transmission mode based on RA resources needs to be determined subsequently.

[0213] 2) If no uplink carrier is specified, the UL (Up Link) carrier is selected according to the second measured value of the signal quality of the reference signal and the corresponding first preset signal quality threshold X2. Optionally, if the second measured value of the signal quality of the reference signal is less than the first preset signal quality threshold X2, the SUL carrier is selected. It should be noted that the first preset signal quality threshold X1 corresponding to the reference signal measured when determining whether to select the SDT transmission mode may be different from the first preset signal quality threshold X2 corresponding to the reference signal measured when selecting the uplink UL carrier, or they may be the same. In addition, for the SDT transmission mode and the non-SDT transmission mode, the first preset signal quality threshold may be different when selecting the uplink UL carrier.

[0214] 3) If it is preliminarily determined that the SDT transmission mode needs to be adopted, it is necessary to determine whether the preconfigured resource usage rule is satisfied. If the preconfigured resource usage rule is satisfied, the target transmission mode is determined to be the SDT transmission mode (CG-SDT) based on preconfigured resources. Among them, optionally, determining whether the preconfigured resource usage rule is satisfied includes: determining whether the second measured value of the signal quality of the synchronization signal block SSB (Synchronization Signal Block) associated with the preconfigured resource exceeds the second preset signal quality threshold, and / or determining whether the preconfigured resource is valid, and / or determining whether the TAT (Timing Advance Timer) has not timed out. If it is determined that the second measured value of the signal quality of the synchronization signal block SSB associated with the preconfigured resource exceeds the second preset signal quality threshold, and / or the preconfigured resource is valid, and / or the TAT has not timed out, it is determined that the preconfigured resource usage rule is satisfied, and the target transmission mode can be determined to be the SDT transmission mode based on preconfigured resources, and then the data to be transmitted is transmitted to the network device in the SDT transmission mode based on preconfigured resources.

[0215] 4) If it is determined that the pre-configured resource usage rules are not satisfied, random access (RA) resources can be selected, and the target transmission mode is determined to be the SDT transmission mode based on RA resources (RA-SDT). Then, the data to be transmitted is transmitted to the network device in the SDT transmission mode based on RA resources.

[0216] 5) If the data to be transmitted fails to be transmitted when SDT is performed using pre-configured resources, or if the data to be transmitted fails to be transmitted when SDT is performed using RA resources, the target transmission mode is determined to be a non-SDT transmission mode. Then, the data to be transmitted is transmitted to the network device in the non-SDT transmission mode.

[0217] Among them, if the cumulative number of SDT transmissions exceeds the preset number threshold, the target transmission mode is also determined to be a non-SDT transmission mode. Then, the data to be transmitted is transmitted to the network device in the non-SDT transmission mode.

[0218] Of course, if the UE is not in the RRC_INACTIVE state, the target transmission mode of the data to be transmitted can also be determined based on the above process according to the SDT configuration information. That is, in this embodiment, it is not necessary to limit the UE to be in the RRC_INACTIVE state.

[0219] Among them, the signal quality in any of the above measured signal quality values or signal quality thresholds includes, but is not limited to, any one of the following: RSRP (Reference Signal Receiving Power), RSRQ (Reference Signal Receiving Quality), or SINR (Signal to Interference plus Noise Ratio).

[0220] S202. Store the relevant information generated during the process of determining the target transmission mode for the data to be transmitted.

[0221] In this embodiment, during the above process of determining the target transmission mode, the relevant information generated during the process of determining the target transmission mode can be stored. This step is an optional step.

[0222] Specifically, storing the relevant information generated during the process of determining the target transmission mode for the data to be transmitted includes at least one of the following:

[0223] Information related to the data volume of the data to be transmitted;

[0224] Information related to the signal quality of the measured reference signal;

[0225] Information related to the determined target transmission mode.

[0226] Among them, optionally, the information related to the data volume of the data to be transmitted includes at least one or more of the following: the data volume of the data to be transmitted, a preset data volume threshold, and the comparison result between the data volume of the data to be transmitted and the preset data volume threshold.

[0227] Optionally, the information related to the signal quality of the measured reference signal includes at least one or more of the following: the measured value of the signal quality of the measured reference signal, a first preset signal quality threshold, and the comparison result between the measured value and the first preset signal quality threshold.

[0228] Furthermore, the signal quality of the reference signal is measured when determining whether to select the SDT transmission mode, or the signal quality of the reference signal is measured when selecting the uplink UL carrier; wherein, the first preset signal quality threshold X1 corresponding to the reference signal measured when determining whether to select the SDT transmission mode may be different from or the same as the first preset signal quality threshold X2 corresponding to the reference signal measured when selecting the uplink UL carrier.

[0229] In an alternative embodiment, if the determined target transmission mode is the SDT transmission mode, the information related to the determined target transmission mode includes at least one or more of the following:

[0230] Timing Advance Timer TAT information;

[0231] Indicator information indicating whether there is an effective preconfigured resource;

[0232] Information related to the signal quality of the Synchronization Signal Block SSB signal associated with the preconfigured resource;

[0233] The transmission type using the SDT transmission mode, where the transmission type includes one of the SDT transmission mode based on the preconfigured resource and the SDT transmission mode based on the Random Access RA resource;

[0234] The cumulative number of SDT transmissions.

[0235] It should be noted that the TAT information includes at least one or more of the TA duration and whether it times out, and may also include other information related to TAT, which is not specifically limited here.

[0236] In another alternative embodiment, if the determined target transmission mode is a non-SDT transmission mode, the information related to the determined target transmission mode includes:

[0237] The reason for using the non-SDT transmission mode.

[0238] Among them, optionally, the reasons for adopting the non-SDT transmission mode include at least one or more of the following:

[0239] The data volume of the data to be transmitted is greater than a preset data volume threshold;

[0240] The measured value of the signal quality of the reference signal is less than a first preset signal quality threshold;

[0241] The measured value of the signal quality of the synchronization signal block SSB associated with the preconfigured resource is less than a second preset signal quality threshold;

[0242] The transmission failure information of the data to be transmitted using the SDT transmission mode;

[0243] The cumulative number of SDT transmissions exceeds a preset transmission number threshold;

[0244] A transmission mode conversion instruction is received, where the transmission mode conversion instruction is used to indicate a conversion to the non-SDT transmission mode.

[0245] It should be noted that the signal quality of the reference signal here can be measured when determining whether to select the SDT transmission mode, or the signal quality of the reference signal can also be measured when selecting the uplink UL carrier; it can also be measured when performing other operations, and no specific limitation is made here.

[0246] Optionally, when storing the relevant information generated during the process of determining the target transmission mode for the data to be transmitted, for the data to be transmitted at different times, the relevant information corresponding to the target transmission mode determined for the data to be transmitted is stored separately, where the relevant information is the relevant information generated during the process of determining the target transmission mode for the data to be transmitted. That is, in this embodiment, if there are multiple data to be transmitted, for different data to be transmitted, the target transmission mode is determined for each data to be transmitted, and the relevant information corresponding to the target transmission mode determined for each data to be transmitted is stored. In the case of obtaining the relevant information corresponding to the target transmission mode determined for each data to be transmitted, a relevant information group is stored, and the relevant information group contains the relevant information corresponding to the target transmission mode determined for each data to be transmitted.

[0247] For example: when determining the target transmission mode for different data to be transmitted, the relevant information corresponding to the target transmission mode determined for the data to be transmitted can be stored separately. For example, the relevant information of one data to be transmitted can be corresponding to the stored data of one entry; the relevant information of multiple data to be transmitted can be corresponding to the stored data of multiple entries respectively, so as to ensure that the subsequent generated storage record data will not overwrite the previously generated storage data.

[0248] Optionally, in this embodiment, the types of signal quality of the first measurement value of the signal quality of the reference signal, the second measurement value of the signal quality of the reference signal, and the measurement value of the signal quality of the synchronization signal block (SSB) associated with the preconfigured resource may be the same or different, and may be any one of RSRP, RSRQ, and SINR.

[0249] S203. Send the relevant information generated during the process of determining the target transmission mode for the data to be transmitted to the network device, where the relevant information is used to optimize the SDT configuration information.

[0250] In this embodiment, after obtaining the relevant information generated during the process of determining the target transmission mode for the data to be transmitted, the UE may send the relevant information to the network device, and the network device may optimize the SDT configuration information based on this relevant information. The specific optimization method is not limited in this embodiment. In addition, the manner in which the UE sends the relevant information to the network device is not limited in this embodiment. For example, the UE may directly send the relevant information to the network device, may send the relevant information to the network device according to the preconfigured reporting information, may send the relevant information to the network device after receiving a request from the network side device, may generate an information report based on the relevant information and then send the information report to the network device, may write the relevant information into reports such as the RA report and the logged MDT measurement report and then send the reports to the network device, or may send the relevant information to the network device through dedicated signaling. Examples are not given one by one here.

[0251] For the data transmission method provided in this embodiment, for the data to be transmitted, determine the target transmission mode of the data to be transmitted according to the SDT configuration information, where the SDT configuration information is configured by the network device; send the relevant information generated during the process of determining the target transmission mode for the data to be transmitted to the network device, where the relevant information is used to optimize the SDT configuration information. This embodiment provides a basis for the network device to optimize the SDT configuration information, which can make the SDT configuration information sent by the network device to the UE more reasonable, thereby guiding and optimizing the next data transmission process of the UE more reasonably.

[0252] Embodiment 2

[0253] Figure 3 is a flowchart of the data transmission method provided in this embodiment. As Figure 3 shown, this embodiment provides a data transmission method, and the execution entity is the UE. The specific steps of this data transmission method are as follows:

[0254] S301. For the data to be transmitted, determine the target transmission mode of the data to be transmitted according to the SDT configuration information, where the SDT configuration information is configured by the network device;

[0255] S302. Send the relevant information generated during the process of determining the target transmission mode for the data to be transmitted to the network device, where the relevant information is used to optimize the SDT configuration information.

[0256] For the data transmission method provided in this embodiment, reference may be made to the above embodiment. In this embodiment, after the UE obtains the relevant information generated during the process of determining the target transmission mode for the data to be transmitted, the relevant information will be sent to the network device, and the relevant information is used to optimize the SDT configuration information.

[0257] Embodiment III

[0258] Figure 4 is a flowchart of the data transmission method provided in this embodiment. As Figure 4 shown, this embodiment provides a data transmission method, and the execution entity is the UE. The specific steps of this data transmission method are as follows:

[0259] S401. For the data to be transmitted, determine the target transmission mode of the data to be transmitted according to the SDT configuration information, where the SDT configuration information is configured by the network device;

[0260] S402. Store the relevant information generated during the process of determining the target transmission mode for the data to be transmitted.

[0261] For the data transmission method provided in this embodiment, reference may be made to the above embodiment. In this embodiment, it is not necessary to pay attention to whether the UE sends the stored relevant information generated during the process of determining the target transmission mode for the data to be transmitted to the network device. For example, in some cases, some network devices do not support optimizing the SDT configuration information according to the relevant information, then the UE may not send the relevant information to these network devices; or, in some cases, the UE may not send all the stored relevant information to the network side device, but send some of the stored relevant information to the network side device. As for whether the terminal sends all or part of the stored relevant information to the network side device, it can be based on the negotiation or protocol regulations between the network side device and the terminal, and the implementation method is not specifically limited here.

[0262] Embodiment IV

[0263] As an optional method, the sending the relevant information to the network device in S203 in the above embodiment may specifically include:

[0264] Generate an information report according to the relevant information generated during the process of determining the target transmission mode for the data to be transmitted, and send the information report to the network device.

[0265] In this embodiment, after obtaining the relevant information generated during the process of determining the target transmission mode for the data to be transmitted, an information report can be generated according to the relevant information. This information report is a report storing the relevant information, such as an SDT report, and then the newly generated information report is sent to the network device.

[0266] Embodiment 5

[0267] As an alternative, the sending of the relevant information to the network device as described in S203 in the above embodiment may specifically include:

[0268] Writing the relevant information into a first report; or, in the case of obtaining the relevant information, generating identification information of the relevant information and writing the identification information into the first report, where the identification information is used to obtain the relevant information corresponding to the identification information;

[0269] Sending the first report to the network device;

[0270] Among them, the first report includes one or more of: RA report, logged MDT measurement report, CEF report, RLF report.

[0271] In this embodiment, the relevant information generated during the process of determining the target transmission mode for the data to be transmitted can be written into the first report. Optionally, the first report includes but is not limited to at least one of the following: RA report, logged MDT measurement report (a report recording MDT measurement values, MDT is Minimization of DriveTests), CEF (Connection Establishment Failure) report, RLF (Radio Link Failure) report. It should be noted that if the first report exists in the UE at the current moment, the relevant information generated during the process of determining the target transmission mode for the data to be transmitted is directly written into the first report; if the first report does not exist in the UE at the current moment, the first report is created and the relevant information generated during the process of determining the target transmission mode for the data to be transmitted is directly written into the first report, and it is not limited whether the first report includes other measurement data that originally needed to be written into the first report.

[0272] In addition, optionally, since relevant information generated during the process of determining the target transmission mode for the data to be transmitted is written into the first report, which causes the first report to change. To enable the network device to extract the relevant information or distinguish the relevant information from the preset content of the first report after receiving the first report, the identification information of the relevant information may be written into the first report. Optionally, the identification information may be 1-bit indication information, where the preset content may be other measurement data. Of course, the other measurement data in the first report may also be empty.

[0273] Embodiment 6

[0274] As Figure 5 shown, as an optional method, the sending of the relevant information to the network device in S203 in the above embodiment may specifically include:

[0275] S501. Send a first dedicated signaling including indication information indicating the availability of the relevant information to the network device;

[0276] S502. Receive a second dedicated signaling sent by the network device requesting the relevant information;

[0277] S503. Send the relevant information to the network device in a third dedicated signaling.

[0278] In this embodiment, considering that some network devices may be currently busy or do not support optimizing the SDT configuration information according to the relevant information generated during the process of determining the target transmission mode for the data to be transmitted, the UE may first send a first dedicated signaling including indication information indicating the availability of the relevant information to the network device. The first dedicated information is used to notify the network device that the relevant information has been stored and is in an available state and can be provided to the network device. After receiving the first dedicated signaling, the network device may determine whether to send a second dedicated signaling requesting the relevant information to the UE according to its own situation. If the UE receives the second dedicated signaling, the UE may send the relevant information to the network device in a third dedicated signaling.

[0279] In another optional embodiment, the network device may pre-configure reporting information for the terminal device, and the terminal device may send the relevant information corresponding to the pre-configured reporting information to the network device.

[0280] In another optional embodiment, the terminal device may receive a request message sent by the network device and send the relevant information to the network device according to the request information.

[0281] To more clearly describe the data transmission method provided in the above embodiment, the following is an exemplary illustration.

[0282] Example 1

[0283] 1) The UE receives the SDT configuration information sent by the network device in the RRC Release message;

[0284] 2) The UE enters the RRC_INACTIVE state. When there are data packets to be transmitted, the UE records the data volume size and the first measurement value (RSRP, RSRQ, or SINR value) of the signal quality of the reference signal at this time, and compares it with the data volume threshold configured by the network device in the SDT configuration information and the first preset signal quality threshold X1 (RSRP, RSRQ, or SINR threshold), and records the relevant information, which may include at least one of the first measurement value of the signal quality of the reference signal, the comparison result between the first measurement value and the first preset signal quality threshold X1, and the first preset signal quality threshold X1; It may also include at least one of the data volume of the data to be transmitted, the preset data volume threshold, and the comparison result between the data volume of the data to be transmitted and the preset data volume threshold;

[0285] 3) When the data volume is less than the data volume threshold, and / or the first measurement value of the signal quality of the reference signal is greater than the first preset signal quality threshold X1, the SDT process is preliminarily determined to be selected;

[0286] 4) The UE selects a UL carrier. The UE records the second measurement value (such as RSRP, RSRQ, or SINR value) of the signal quality of the UL carrier selection process, and compares it with the first preset signal quality threshold X2 (RSRP, RSRQ, or SINR threshold) configured by the network device in the SDT configuration information, and records the relevant information, which may include at least one of the second measurement value of the signal quality of the reference signal, the comparison result between the second measurement value and the first preset signal quality threshold X2, and the first preset signal quality threshold X2;

[0287] 5) After selecting the UL carrier, the UE judges the CG criterion, measures the measurement value (RSRP, RSRQ, or SINR value) of the signal quality of the SSB associated with the CG resource, and judges the duration of the TA timer. At this time, record the measurement value of the signal quality of the SSB, record the duration of the TA timer, and compare it with the second preset signal quality threshold (RSRP, RSRQ, or SINR threshold) configured by the network device in the SDT configuration information, and judge whether the TA timer times out, and record the relevant information, which may include at least one of the following: the duration of the timing advance timer TAT, and / or whether the TAT times out; the measurement value of the signal quality of the synchronization signal block SSB associated with the preconfigured resource, the second preset signal quality threshold, and at least one of the comparison results between the measurement value of the signal quality of the SSB and the second preset signal quality threshold; the indication information of whether there is an effective preconfigured resource;

[0288] 6) When the UE determines that the CG criterion is satisfied, it uses the CG resource to send small data packets and records the number of times of transmitting the SDT.

[0289] 7) Save the above relevant information in an information report, such as an SDT report, and send it to the network device.

[0290] Example 2

[0291] 1) The UE receives the SDT configuration information sent by the network device in the RRC Release message;

[0292] 2) The UE enters the RRC_INACTIVE state. When there is a data packet to be transmitted, the UE records the data volume size and the first measurement value of the signal quality of the reference signal at this time (RSRP, RSRQ, or SINR value), and compares it with the data volume threshold and the first preset signal quality threshold X1 (RSRP, RSRQ, or SINR threshold) configured by the network device in the SDT configuration information, and records the relevant information, which may include at least one of the first measurement value of the signal quality of the reference signal, the comparison result between the first measurement value and the first preset signal quality threshold X1, and the first preset signal quality threshold X1; It may also include at least one of the data volume of the data to be transmitted, the preset data volume threshold, and the comparison result between the data volume of the data to be transmitted and the preset data volume threshold;

[0293] 3) When the data volume is greater than the data volume threshold and the first measurement value is greater than the first preset signal quality threshold X1, the non-SDT process is selected, and the reason for selecting the non-SDT is recorded as the data volume being greater than the data volume threshold;

[0294] 4) Then the above relevant information is saved in an information report, such as an SDT report, and sent to the network device.

[0295] Example 3

[0296] 1) The UE receives the SDT configuration information sent by the network device in the RRC Release message;

[0297] 2) The UE enters the RRC_INACTIVE state. When there are data packets to be transmitted, the UE records the size of the data volume and the first measurement value of the signal quality of the reference signal at this time (RSRP, RSRQ, or SINR value), and compares it with the data volume threshold configured by the network device in the SDT configuration information and the first preset signal quality threshold X1 (RSRP, RSRQ, or SINR threshold), and records the relevant information, which may include at least one of the first measurement value of the signal quality of the reference signal, the comparison result between the first measurement value and the first preset signal quality threshold X1, and the first preset signal quality threshold X1; it may also include at least one of the data volume of the data to be transmitted, the preset data volume threshold, and the comparison result between the data volume of the data to be transmitted and the preset data volume threshold;

[0298] 3) When the data volume is less than the data volume threshold and / or the first measurement value is greater than the first preset signal quality threshold, the SDT process is preliminarily determined to be selected;

[0299] 4) The UE selects a UL carrier. The UE records the second measurement value of the signal quality of the reference signal in the UL carrier selection process (such as RSRP, RSRQ, or SINR value), and compares it with the first preset signal quality threshold X2 (RSRP, RSRQ, or SINR threshold) configured by the network device in the SDT configuration information, and records the relevant information, which may include at least one of the second measurement value of the signal quality of the reference signal, the comparison result between the second measurement value and the first preset signal quality threshold X2, and the first preset signal quality threshold X2;

[0300] 5) The UE judges the CG criterion, measures the measurement value of the signal quality of the SSB associated with CG (RSRP, RSRQ, or SINR value), and judges the duration of the TA timer. At this time, record the measurement value of the signal quality of the SSB, record the duration of the TA timer, and compare it with the second preset signal quality threshold (RSRP, RSRQ, or SINR threshold) configured by the network device in the SDT configuration information, and judge whether the TA timer times out, and record the relevant information, which may include at least one of the following: the duration of the timing advance timer TAT and / or whether TAT times out; the measurement value of the signal quality of the synchronization signal block SSB associated with the preconfigured resource, the second preset signal quality threshold, and at least one of the comparison results between the measurement value of the signal quality of the SSB and the second preset signal quality threshold; the indication information of whether there is an effective preconfigured resource;

[0301] 6) When the UE judges that the CG criterion is not satisfied, it selects RA resources to send small data packets according to the RA criterion and records the number of times of transmitting SDT;

[0302] 7) After the subsequent UE accesses the network through random access, it will record the information related to the RA process and save the RA report. Then, the above-recorded SDT-related information can be saved in the RA report, and identification information is added to the RA report to distinguish the relevant information from the original content of the RA report.

[0303] Example 4

[0304] 1) The UE receives the SDT configuration information and the logged MDT measurement configuration sent by the network device in the RRC Release message.

[0305] 2) The UE enters the RRC_INACTIVE state. When there is a data packet to be transmitted, the UE records the data volume size and the first measurement value of the signal quality of the reference signal at this time (RSRP, RSRQ, or SINR value), and compares it with the data volume threshold and the first preset signal quality threshold X1 (RSRP, RSRQ, or SINR threshold) configured by the network device in the SDT configuration information, and records the relevant information, which may include at least one of the first measurement value of the signal quality of the reference signal, the comparison result between the first measurement value and the first preset signal quality threshold X1, and the first preset signal quality threshold X1; it may also include at least one of the data volume of the data to be transmitted, the preset data volume threshold, and the comparison result between the data volume of the data to be transmitted and the preset data volume threshold.

[0306] 3) When the data volume is less than the data volume threshold and / or the first measurement value is greater than the first preset signal quality threshold X1, it is preliminarily determined to select the SDT process.

[0307] 4) The UE selects the UL carrier. The UE records the second measurement value of the signal quality of the UL carrier selection process (such as RSRP, RSRQ, or SINR value), and compares it with the first preset signal quality threshold X2 (RSRP, RSRQ, or SINR threshold) configured by the network device in the SDT configuration information, and records the indication information, which may include at least one of the second measurement value of the signal quality of the reference signal, the comparison result between the second measurement value and the first preset signal quality threshold X2, and the first preset signal quality threshold X2.

[0308] 5) The UE determines the CG criterion, measures the signal quality of the SSB associated with CG (RSRP, RSRQ, or SINR value), and determines the duration of the TA timer. At this time, the measured value of the signal quality of the SSB is recorded, the duration of the TA timer is recorded, and it is compared with the second preset signal quality threshold (RSRP, RSRQ, or SINR threshold) configured by the network device in the SDT configuration information, and it is determined whether the TA timer times out. The relevant information can be recorded, including at least one of the following: the duration of the timing advance timer TAT, and / or whether the TAT times out; the measured value of the signal quality of the synchronization signal block SSB associated with the preconfigured resource, the second preset signal quality threshold, and at least one of the comparison results between the measured value of the signal quality of the SSB and the second preset signal quality threshold; the indication information of whether there is an effective preconfigured resource;

[0309] 6) When the UE determines that the CG criterion is met, it uses the CG resource to send small data packets;

[0310] 7) The UE simultaneously performs logged MDT measurements and records the logged measurement results;

[0311] 8) After the UE accesses the network subsequently, the relevant information can be reported together with the logged MDT measurement report, and identification information is added to the logged MDT measurement report to distinguish the relevant information from the original content of the logged MDT measurement report.

[0312] Example 5

[0313] 1) The UE receives the SDT configuration information and / or the logged MDT measurement configuration sent by the network device in the RRC Release message;

[0314] 2) The UE enters the RRC_INACTIVE state. When there is a data packet to be transmitted, the UE records the data volume size and the first measured value of the signal quality of the reference signal at this time (RSRP, RSRQ, or SINR value), and compares it with the data volume threshold and the first preset signal quality threshold X1 (RSRP, RSRQ, or SINR threshold) configured by the network device in the SDT configuration information, and records the relevant information, which can include at least one of the first measured value of the signal quality of the reference signal, the comparison result between the first measured value and the first preset signal quality threshold X1, and the first preset signal quality threshold X1; It can also include at least one of the data volume of the data to be transmitted, the preset data volume threshold, and the comparison result between the data volume of the data to be transmitted and the preset data volume threshold;

[0315] 3) When the data volume is less than the data volume threshold, and / or the first measurement value is greater than the first preset signal quality threshold X1, then preliminarily determine to select the SDT process;

[0316] 4) The UE selects a UL carrier, and the UE records the second measurement value of the signal quality of the reference signal in the UL carrier selection process (such as RSRP, RSRQ, or SINR value), and compares it with the first preset signal quality threshold X2 (RSRP, RSRQ, or SINR threshold) configured in the SDT configuration information by the network device, and records the relevant information, which may include at least one of the second measurement value of the signal quality of the reference signal, the comparison result between the second measurement value and the first preset signal quality threshold X2, and the first preset signal quality threshold X2;

[0317] 5) The UE judges the CG criterion, measures the measurement value (RSRP, RSRQ, or SINR value) of the signal quality of the SSB associated with the CG, and judges the duration of the TA timer. At this time, record the measurement value of the signal quality of the SSB, record the duration of the TA timer, and compare it with the second preset signal quality threshold (RSRP, RSRQ, or SINR threshold) configured in the SDT configuration information by the network device, and judge whether the TA timer times out, and record the relevant information, which may include at least one of the following: the duration of the timing advance timer TAT, and / or whether the TAT times out; the measurement value of the signal quality of the synchronization signal block SSB associated with the preconfigured resource, the second preset signal quality threshold, and at least one of the comparison results between the measurement value of the signal quality of the SSB and the second preset signal quality threshold; the indication information of whether there is an effective preconfigured resource.

[0318] 6) If the UE judges that the CG criterion is not satisfied, select the RA process to send small data packets;

[0319] 7) If the UE fails to successfully send small data packets through the RA resource, for example, the cumulative number of SDT transmissions exceeds the configured threshold, then it will send small data packets through a non-SDT process and record the reason for performing the non-SDT process.

[0320] 8) The above relevant information is saved in the SDT report and sent to the network device.

[0321] Example 6

[0322] 1) The UE may report, in a first dedicated signaling (such as RRC Setup Complete / RRC Reconfiguration Complete / RRC Reestablishment Complete / RRC Resume Complete), an indication information indicating that the relevant information generated during the process of determining the target transmission mode for the data to be transmitted is available;

[0323] 2) The network device requests the UE to report, in a second dedicated signaling (such as RRC Reconfiguration / UE Information Request), the relevant information generated during the process of determining the target transmission mode for the data to be transmitted;

[0324] 3) The UE subsequently reports, in a third dedicated signaling (such as UE Information Response), the recorded relevant information generated during the process of determining the target transmission mode for the data to be transmitted.
