The reporting method/device/equipment and storage medium provided by the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

Figure 2 is a schematic flowchart of a reporting method provided by an embodiment of the present disclosure. The method is executed by a terminal device. As shown in Figure 2, the reporting method may include the following steps:

Step 201: Report the instruction information to the network device.

The disclosed method can be applied to New Radio unlicensed (NR-U) systems. And, in one embodiment of the present disclosure, the above indication information can be used to indicate whether the payload of MsgA and/or the preamble of MsgA are successfully sent in the 2-step random access process.

Further, in one embodiment of the present disclosure, the above indication information is also used to indicate the reason why the payload of MsgA was not successfully sent, and/or the reason why the preamble of MsgA was not successfully sent; wherein, the indication information may also indicate At least one of the following:

Is the reason why the terminal device fell back from the 2-step random access process to the 4-step random access process because: MsgA's payload failed to be sent due to a listen-before-talk (LBT) failure;

Whether the preamble of MsgA failed to be sent due to LBT failure;

Whether the payload of MsgA failed to be sent due to LBT failure;

The preamble of MsgA is sent successfully, and the payload of MsgA cannot be sent due to LBT failure.

It can be seen from the above content that in the embodiment of the present disclosure, the terminal device will report to the network device "indication information for indicating whether the payload of MsgA and/or the preamble of MsgA are successfully sent, and the reason why the payload of MsgA and/or the preamble of MsgA are not successfully sent", wherein the indication information is reported to the network device after the terminal device successfully accesses the random access. And, the indication information can be used for: when the terminal device falls back from the 2-step random access process to the 4-step random access process, the network device can determine the reason why the 2-step random access process falls back to the 4-step random access process based on the indication information.

Specifically, in one embodiment of the present disclosure, when a terminal device initiates a 2-step random access process, it may fall back to a 4-step random access process due to some reasons. The reason may be at least one of the following:

The number of times MsgA is sent reaches the threshold (such as msgA-TransMax);

The terminal device receives the fallbackRAR (fallback random response) sent by the network device, where the fallbackRAR is sent to the terminal device when the network device does not receive the payload of msgA;

The terminal device sent the preamble of msgA, but the payload of msgA failed to be sent successfully.

Referring to the above reasons, it can be seen that the reason causing the terminal device to fall back from the 2-step random access process to the 4-step random access process is essentially: the preamble of MsgA was not successfully sent and/or the payload of MsgA was not sent successfully. And, further, the reason why the preamble of MsgA is not sent successfully and/or the payload of MsgA is not sent successfully may be that the poor quality of the uplink signal causes the network device to be unable to decode it correctly, resulting in the network device being unable to receive the preamble and/or the payload of MsgA. The payload of MsgA, or it may be that the terminal device fails to send the preamble of MsgA and/or the payload of MsgA due to LBT failure.

Based on this, in this disclosure, by reporting to the network device the indication information "used to indicate whether the payload of MsgA and/or the preamble of MsgA in the 2-step random access process is successfully sent", when a 2-step random access occurs on the terminal device, When the access process falls back to the 4-step random access process, the network device can determine the cause of the 2-step random access process falling back to the 4-step random access process based on the indication information. For example, it can be determined that it is due to MsgA. The 2-step random access process caused by the unsuccessful transmission of the payload falls back to the 4-step random access process, or it is determined that the 2-step random access process is caused by the unsuccessful transmission of MsgA's preamble and falls back to the 4-step random access process. .

Further, when the payload of MsgA and/or the preamble of MsgA are not successfully sent, the indication information in this disclosure will also indicate the reason why the payload of MsgA and/or the preamble of MsgA are not successfully sent (such as whether it is due to LBT failure. causing the payload of MsgA and/or the preamble of MsgA to be unsuccessfully sent), the network device can further determine the reason for the payload of MsgA and/or the preamble of MsgA to be unsuccessfully sent based on the indication information, so as to perform corresponding optimization based on the reason. Adjustment is made to ensure that the payload of MsgA and the preamble of MsgA can be sent successfully in the subsequent 2-step random access process, so as to avoid the fallback from the 2-step random access process to the 4-step random access process when the subsequent terminal device is randomly accessed. situation.

To sum up, in the reporting method provided by the embodiment of the present disclosure, the terminal device will report indication information to the network device. The indication information is used to indicate the payload of MsgA and/or the preamble of MsgA in the 2-step random access process. Whether sent successfully. Among them, the main reasons that cause the 2-step random access process to fall back to the 4-step random access process are: the payload of MsgA is not sent successfully and/or the preamble of MsgA is not sent successfully. Based on this, the terminal device reports the process to the network device. Instruction information, when the terminal equipment falls back to the 4-step random access process from the 2-step random access process, the network device can determine based on the instruction information what caused the 2-step random access process to fall back to the 4-step random access process. Specific reasons, and corresponding optimization adjustments can be made based on the specific reasons to improve the efficiency of subsequent random access.
