Description

Processing method, communication device and storage medium TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, in particular to a processing method, a communication device and a storage medium. BACKGROUND

[0002] In the existing RACH (Physical Random Access CHannel, random access channel) process, when the terminal device fails to send more than a certain number of times, the coverage level is raised, and the attempt is continued according to the raised coverage level parameter (such as higher repetition) to avoid sending failure due to coverage.

[0003] In the process of conceiving and implementing the present application, the inventors have found at least the following problems:

[0004] For CB-Msg3 (Contention-Based Msg3, contention-based message 3) transmission in the NTN (Non-Terrestrial Network, non-terrestrial network) scenario, the terminal device selects the coverage level according to the RSRP (Reference Signal Receiving Power, reference signal receiving power). Since the RSRP does not change significantly in the NTN scenario and / or the terminal device uses shared PUSCH (Physical Uplink Shared CHannel, physical uplink shared channel) resources to send CB-Msg3, when CB-Msg3 fails to send, it may be due to conflict. If the existing transmission mechanism is used, it may cause unnecessary coverage level to be raised, therefore, it is necessary to optimize the transmission mechanism of CB-Msg3 to reduce or avoid the terminal device from raising the coverage level due to continuous failure caused by conflict.

[0005] The foregoing narrative is intended to provide general background information and does not necessarily constitute prior art. TECHNICAL SOLUTION

[0207] Optionally, the terminal device starts a first monitoring window after transmitting the first message (copy).

[0208] Optionally, the terminal device monitors a physical downlink control channel (PDCCH) scrambled by a radio network temporary identifier (RNTI) within the first monitoring window.

[0209] Optionally, if the terminal device monitors the PDCCH scrambled by the RNTI within the first monitoring window and receives a response message corresponding to the first message, and the response message carries a contention resolution identifier matching the terminal device, the terminal device stops the first monitoring window, confirms that the contention resolution is successful, and considers that the first message is successfully transmitted.

[0210] Optionally, when the first message is successfully transmitted, if there are remaining copies to be transmitted, the terminal device stops transmitting the remaining copies.

[0214] Optionally, the copy transmission failure of the first message of the terminal device includes a first reason failure and / or a second reason failure.

[0215] Optionally, the reason for the one-time transmission failure of the first message of the terminal device is determined based on the distribution of all copy transmission failure reasons in the one-time transmission of the first message.

[0216] Optionally, if all copies in the one-time transmission of the first message are first reason failures or the number of first reason failures is greater than or equal to the number of second reason failures, the one-time transmission of the first message is confirmed to fail due to the first reason.

[0220] Optionally, in the first message sending failure scenario, the sending failure reason analysis logic can refer to FIG. 6.

[0221] Optionally, if the terminal device does not receive the physical downlink control channel scrambled by the wireless network temporary identifier and / or the reference signal received power is near the coverage level threshold, the terminal device is recorded as a first reason failure.

[0222] Optionally, when the network device detects that the signal strength indicator (RSSI) is very low on the corresponding resource, it can be considered that no terminal device sends data on the corresponding resource, so the physical downlink control channel scrambled by the wireless network temporary identifier is not sent.

[0227] Optionally, the network device can judge whether there is a conflict according to the received signal strength indicator (RSSI), such as the corresponding physical uplink shared channel fails to be parsed but the signal strength indicator RSSI is high, which can be considered as a conflict caused by the terminal device sending on the resource, so the conflict can be indicated by the physical downlink control channel.

[0228] Optionally, after the terminal device confirms the first message sending failure, the corresponding processing is performed in combination with the maximum sending attempt number X of the coverage level, such as continuing to attempt to send the first message at the current coverage level, or judging the main reason (such as a coverage reason or a conflict reason) for the failure of this time of sending the first message, and performing different processing according to different failure reasons. Thus, the transmission mechanism of CB-Msg3 in the NTN scenario is optimized to reduce or avoid the terminal device from continuously sending failures due to a conflict reason when the coverage level is increased.

[0229] Optionally, the terminal device performs different processing according to different failure reasons in the first message sending failure scenario, and the flow can refer to FIG. 7.

[0230] Optionally, after the first message sending failure, if the first message sending attempt number of the terminal device is less than the maximum sending attempt number X of the current coverage level, the terminal device continues to attempt to send the first message at the current coverage level.

[0232] Optionally, the terminal device performs the second processing, including at least one of the following:

[0233] If all (replicated) sending of the first message is a first reason failure or the number of first reason failures is greater than or equal to the number of second reason failures, the terminal device increases the current coverage level to continue to attempt to send the first message; optionally, if the current coverage level is the highest, the terminal device uses a random access process (indicating that the main reason for the sending failure is a coverage reason).

[0234] If all (replicated) sending of the first message is a second reason failure or the number of second reason failures is greater than or equal to the number of first reason failures, the terminal device continues to attempt to send the first message at the current coverage level (indicating that the main reason for the sending failure is a conflict reason).

[0235] Optionally, the terminal device continues to attempt to send the first message at the current coverage level, including at least one of the following:

[0236] Continue to attempt to send the first message after adjusting the first time window;

[0237] Continue to attempt to send the first message after adjusting the number of replicated sending;

[0238] Continue to attempt to send the first message using a random access process.

[0239] Optionally, when the number of sending the first message reaches the maximum sending attempt number X and / or when all sending of the first message is second reason failure or the number of second reason failure is greater than or equal to the number of first reason failure, the terminal device continues to attempt to send the first message after adjusting the first time window.

[0240] Optionally, the terminal device adjusts the first window length according to a window adjustment step.

[0241] Optionally, after the terminal device adjusts the first window length, the terminal device selects N copies of the first message to be sent at N occasions within the newly adjusted first time window.

[0242] Optionally, when the number of times of adjusting the first time window by the terminal device is greater than the maximum number of window adjustments Y, the terminal device uses a random access procedure.

[0243] Optionally, when the number of times of adjusting the first time window by the terminal device is less than or equal to the maximum number of window adjustments Y, the terminal device sends the first message using the adjusted window length.

[0244] Optionally, when the number of sending the first message reaches the maximum sending attempt number X and / or when all sending (copies) of the first message is second reason failure or the number of second reason failure is greater than or equal to the number of first reason failure, the terminal device continues to attempt to send the first message after reducing the number of sending copies N.

[0245] Optionally, when the current number of sending copies by the terminal device is a first value, the terminal device uses a random access procedure.

[0246] Optionally, when the current number of sending copies by the terminal device is not the first value, the terminal device sends the first message using a reduced or adjusted number of sending copies.

[0247] Optionally, when the number of sending the first message reaches the maximum sending attempt number X and / or when all sending (copies) of the first message is second reason failure or the number of second reason failure is greater than or equal to the number of first reason failure, the terminal device adjusts the number of sending copies to be the first value.

[0248] Optionally, the first value is 1.

[0249] Optionally, when the current number of sending copies of the first message is 1, the terminal device stops using the first message, i.e., uses a random access procedure.

[0250] Optionally, when the current number of sending copies of the first message is greater than 1, the terminal device reduces the number of sending copies N of the first message to 1 and continues to attempt to send the first message.

[0251] Optionally, when the first message sending number reaches the maximum sending attempt number X and / or when all (replicated) sending of the first message is second reason failure or the second reason failure number is greater than or equal to the first reason failure number, the terminal device stops using the first message and directly uses the random access procedure.

[0252] Therefore, when the first message sending number reaches the maximum sending attempt number X and / or when all (replicated) sending of the first message is second reason failure or the second reason failure number is greater than or equal to the first reason failure number, the terminal device at least one of adjusts the first time window, adjusts the replicated sending number, adjusts the replicated sending number to the first value, and stops using the first message and directly uses the random access procedure to continue attempting to send the first message, thereby optimizing the processing mechanism of DSA, avoiding or reducing the negative gain caused by using DSA when the network load is high, or optimizing the DSA related configuration, and supporting improving system performance.

[0253] Through the technical solutions of the embodiment, the terminal device sends the first message based on the second configuration information, which optimizes the transmission mechanism of CB-Msg3 in the NTN scenario to reduce or avoid improving the coverage level when the terminal device continuously fails to send due to collision reasons.
