In other words, SDT technology can complete the purpose of small data transmission through a very simple signaling process.

[0065] The technical solutions provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0066] like Figure 2 The diagram shown illustrates a flowchart of an information reporting method 200 provided in an exemplary embodiment of this application. This method 200 can be executed by, but is not limited to, a terminal, specifically by hardware and / or software installed in the terminal. In this embodiment, the method 200 may include at least the following steps.

[0067] S210, the terminal reports the first information to the network-side device.

[0068] The first information refers to information received by the terminal during the Configuration Grant (CG) SDT process. For example, it may include information on whether a configuration or process meets the evaluation criteria when the terminal evaluates the initial SDT, information related to the successful execution of the SDT by the terminal, and information related to the failure of the SDT execution (such as the reason for failure and relevant configuration information at the time of failure). This embodiment does not impose any limitations on this.

[0069] Accordingly, after receiving the first information, the network-side device can forward the first information to other network nodes. These other network nodes can be the target network node corresponding to the serving cell where the terminal is located during the CG SDT process. This allows the target network node to adaptively adjust and modify the configured SDT parameters based on the first information, ensuring the successful execution of subsequent CG SDT processes and improving the stability and reliability of wireless communication. The serving cell corresponding to the target network node can be determined based on the serving cell identifier included in the first information, or it can be determined by protocol agreement or configured by the network-side device; no restrictions are imposed here.

[0070] In this embodiment, the terminal reports first information to the network-side device, thereby assisting the network-side device in adaptively adjusting and modifying the configured SDT parameters to ensure the successful execution of the CG SDT process and improve the stability and reliability of wireless communication.

[0071] For example, if the network-side device configures the terminal with CG SDT, but the terminal encounters a problem during the execution of CG SDT, or fails to execute CG SDT successfully due to unreasonable CG SDT parameter configuration, then the terminal can report the relevant information (i.e., the first information) to the network-side device, thereby assisting the network-side device in correcting the SDT parameter configuration to ensure the smooth execution of subsequent CG SDT processes.

[0072] like Figure 3 The diagram shown illustrates a flowchart of an information reporting method 300 provided in an exemplary embodiment of this application. This method 300 can be executed by, but is not limited to, a terminal, specifically by hardware and / or software installed in the terminal. In this embodiment, the method 300 may include at least the following steps.

[0073] S310, the terminal determines the first information based on the target configuration information.

[0074] The target configuration information can be implemented by protocol agreement, higher-level configuration, or network-side configuration. In one implementation, the target configuration information may include at least one of the following (001)-(003).

[0075] (001) Whether the terminal enables the recording of the first information.

[0076] That is, whether or not the terminal is allowed to start recording CG SDT information.

[0077] (002) Allow the terminal to record the area information of the first information.

[0078] That is, in which areas can the terminal record the first information?

[0079] (003) Allow the number of CG procedure entries included in the first information, such as M entries, wherein the CG procedure entries record relevant information about the CG SDT process.

[0080] It is understood that, in this embodiment, when the terminal reports the first information, the first information may include up to M CG procedure entries, and each CG procedure may contain relevant information recorded in this CG SDT. Optionally, M is an integer greater than or equal to 0, and M can be implemented through protocol agreement, protocol predefinition, network configuration, higher-layer configuration, etc., and is not limited here.

[0081] Furthermore, the aforementioned "determining the first information" can be understood as recording the first information, storing the first information, etc., and is not limited here.

[0082] S320, the terminal sends a fifth instruction message to the network-side device.

[0083] The fifth indication information is used to indicate to the network-side device that the terminal stores the first information, so that the network-side device can determine whether the terminal needs to report the first information according to communication requirements.

[0084] Optionally, the fifth indication information and / or the subsequent sixth indication information can be transmitted via RRC signaling.

[0085] S330: The terminal reports the first information to the network-side device.

[0086] The first information is information obtained when the terminal executes the CG SDT process.

[0087] It is understood that, in addition to referring to the relevant description in method embodiment 200, the implementation process of S330 can also be referred to again as a possible implementation method. Figure 3 As shown, the implementation process of S330 may also include S331, the contents of which are as follows.

[0088] S331, upon receiving the sixth instruction information sent by the network-side device, the terminal reports the first information to the network-side device.

[0089] The sixth indication information is used to instruct the terminal to report the first received information.

[0090] As one possible implementation, the first information may include at least one of the following (101)-(116).

[0091] (101) The identifier (ID) of the serving cell in which the terminal executes the CG SDT.

[0092] The serving cell ID includes at least one of the following (101a)-(101b).

[0093] (101a) NR Cell Global Identifier (CGI).

[0094] (101b) The ID of the physical cell. Optionally, if the serving cell ID includes the physical cell ID, the first information may further include the frequency information corresponding to the physical cell.

[0095] (102) A first timer is used to indicate the length of time the terminal takes to execute the CG SDT process.

[0096] The first timer can be determined by the terminal itself, configured by the network-side device, agreed by the protocol, or configured by a higher layer, and there are no restrictions on this.

[0097] In one implementation, the timing length of the first timer can be determined according to at least one of (102a)-(102c) below.

[0098] (102a) The timing length of the first timer, which is used to determine whether the CG SDT has failed, that is, the first timer may be an SDT failure detection timer.

[0099] In this embodiment, the operation of the first timer can be as follows: when the terminal transmits an RRC recovery request (Resume Request, or Resume Request 1), the first timer is started; and when the first timer times out (or expires), the execution of the CG SDT is determined to have failed.

[0100] (102b) The timing length of the second timer, the start time of the second timer is determined according to the transmission time of the RRC recovery request, and the end time of the second timer is determined according to the reception time of the second information or the cell reselection time. The second information includes at least one of the following: RRC Resume message, RRC Setup message, RRC Release message, RRC Release with suspend Configure message, RRC Reject message, and Non-Access Stratum (NAS) layer connection establishment interruption indication.

[0101] (102c) The difference between the timing length of the first timer and the timing length of the second timer.

[0102] It should be noted that, similar to the first timer mentioned above, the first timer, the second timer, and the subsequent second, third, fourth, fifth, and sixth timers described in this embodiment can all be determined by the terminal itself, configured by the network-side device, agreed upon by the protocol, or configured by higher layers, etc., and will not be elaborated further hereafter.

[0103] (103) The second timer (also known as the Time alignment timer) is used to indicate the length of time for the terminal to determine whether the target Time Alignment Group (TAG) is valid. The target TAG is associated with the serving cell where the terminal is located when it performs the CG SDT process.

[0104] In one implementation, the timing length of the second timer can be determined according to at least one of (103a)-(103c) below.

[0105] (103a) The timing length of the third timer, which is used to determine whether the target TAG is in a valid time period.

[0106] In other words, the function of the third timer (i.e., TAT-SDT) is for the terminal to determine whether the target TAG associated with the current serving cell is within the valid time period.

For example, the end time of the fourth timer can be determined based on the transmission time of the CG SDT triggered by the CG or the dynamic grant (DG) issued by the network side.

[0110] (104) A third timer is used to indicate the time window during which the terminal waits for the network-side device to respond after completing the SDT using CG resources, i.e., pur-Response Window Timer.

[0125] (106c) The difference between the third value and the fourth value.

[0126] (107) The third threshold value is used to indicate the SS-RSRP threshold value when the terminal performs the CG SDT process.

[0133] For example, when the terminal selects NUL, that is, when the current RSRP is higher than the fourth threshold, the CG resource indicated by the first indication information is a resource located on NUL; otherwise, it is a resource located on SUL.

[0134] (109) First indication information, used to indicate whether the CG resources of the terminal are on NUL or SUL when performing CG SDT.

[0146] The TAT did not time out. It can be understood that the function of the TAT is for the terminal to determine whether the target TAG associated with the currently serving cell is within its valid time frame.

[0147] The RSRP fluctuation value of the terminal is within the pre-configured RSRP fluctuation range of network layer devices, etc.

[0157] In addition, when transmitting the third indication information, the terminal can indicate the multiple second events that occur one by one through multiple fields, or it can indicate the second event that occurs during the execution of CG SDT through a single field, without indicating which specific event it is.

[0158] (112) First mapping relationship, the first mapping relationship is the mapping relationship between the SSB index and CG index selected by the terminal.
