Abstract

Disclosed in the present application are a processing method, a communication device, and a storage medium. The processing method comprises: a terminal device sending a first message on the basis of second configuration information. By means of the technical solution of the present application, a transmission mechanism for a CB-Msg3 in an NTN scenario is optimized, so as to reduce or avoid the increase in a coverage level when a terminal device has successive transmission failures due to a conflict.

Description

Processing method, communication device and storage medium Technical Field

The present application relates to the field of communication technology, and in particular to a processing method, a communication device and a storage medium.

Background Art

In the existing RACH (Physical Random Access CHannel) process, when the terminal device fails to send more than a certain number of times, the coverage level will be increased, and attempts will continue according to the increased coverage level parameters (such as higher repetition) to avoid sending failures due to coverage reasons.

In the process of conceiving and implementing this application, the inventor found that there are at least the following problems:

For CB-Msg3 (Contention-Based Msg3) transmission in NTN (Non-Terrestrial Network) scenario, the terminal device selects the coverage level according to RSRP (Reference Signal Receiving Power). Since the RSRP does not change significantly in the NTN scenario and/or the terminal device uses the shared PUSCH (Physical Uplink Shared CHannel) resource to send CB-Msg3, when CB-Msg3 transmission fails, it may be due to a conflict. If the existing transmission mechanism is used, it may cause unnecessary coverage level increase. Therefore, it is necessary to optimize the CB-Msg3 transmission mechanism to reduce or avoid continuous failure of terminal devices due to conflicts and improve the coverage level.

The preceding description is intended to provide general background information and does not necessarily constitute prior art.

Please refer to FIG1, which is a schematic diagram of the hardware structure of a mobile terminal for implementing various embodiments of the present application. The mobile terminal 100 may include: a radio frequency unit 101, a WiFi module 102, an audio output unit 103, an A/V (audio/video) input unit 104, a sensor 105, a display unit 106, a user input unit 107, an interface unit 108, a memory 109, a processor 110, and a power supply 111. Those skilled in the art will appreciate that the mobile terminal structure shown in FIG1 does not constitute a limitation on the mobile terminal, and the mobile terminal may include more or fewer components than shown, or combine certain components, or arrange the components differently.

The following is a detailed introduction to the various components of the mobile terminal in conjunction with Figure 1:

The radio frequency unit 101 can be used for receiving and sending signals during information transmission or communication. Specifically, after receiving the downlink information of the base station, it is sent to the processor 110 for processing; in addition, the uplink data is sent to the base station. Generally, the radio frequency unit 101 includes but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier, a duplexer, etc. And/or, the radio frequency unit 101 can also communicate with the network and other devices through wireless communication. The above-mentioned wireless communications may use any communication standard or protocol, including but not limited to GSM (Global System of Mobile communication), GPRS (General Packet Radio Service), CDMA2000 (Code Division Multiple Access 2000), WCDMA (Wideband Code Division Multiple Access), TD-SCDMA (Time Division Synchronous Code Division Multiple Access), FDD-LTE (Frequency Division Duplexing-Long Term Evolution), TDD-LTE (Time Division Duplexing-Long Term Evolution), 5G and 6G, etc.

WiFi is a short-range wireless transmission technology. The mobile terminal can help users send and receive emails, browse web pages, and access streaming media through the WiFi module 102, which provides users with wireless broadband Internet access. Although FIG1 shows the WiFi module 102, it is understandable that it is not a necessary component of the mobile terminal and can be omitted as needed without changing the essence of the invention.

The audio output unit 103 can convert the audio data received by the RF unit 101 or the WiFi module 102 or stored in the memory 109 into an audio signal and output it as sound when the mobile terminal 100 is in a call signal reception mode, a talk mode, a recording mode, a voice recognition mode, a broadcast reception mode, etc. Moreover, the audio output unit 103 can also provide audio output related to a specific function performed by the mobile terminal 100 (for example, a call signal reception sound, a message reception sound, etc.). The audio output unit 103 may include a speaker, a buzzer, etc.

The A/V input unit 104 is used to receive audio or video signals. The A/V input unit 104 may include a graphics processor (GPU) 1041 and a microphone 1042, and the graphics processor 1041 processes the image data of a static picture or video obtained by an image capture device (such as a camera) in a video capture mode or an image capture mode. The processed image frame can be displayed on the display unit 106. The image frame processed by the graphics processor 1041 can be stored in the memory 109 (or other storage medium) or sent via the radio frequency unit 101 or the WiFi module 102. The microphone 1042 can receive sound (audio data) via the microphone 1042 in operating modes such as a phone call mode, a recording mode, and a voice recognition mode, and can process such sound into audio data. The processed audio (voice) data can be converted into a format output that can be sent to a mobile communication base station via the radio frequency unit 101 in the case of a phone call mode. The microphone 1042 can implement various types of noise elimination (or suppression) algorithms to eliminate (or suppress) noise or interference generated in the process of receiving and sending audio signals.

The mobile terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the display panel 1061 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 1061 and/or the backlight when the mobile terminal 100 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that identify the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can be configured on the mobile phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be repeated here.

Optionally, the user input unit 107 may include a touch panel 1071 and other input devices 1072. The touch panel 1071, also known as a touch screen, can collect the user's touch operation on or near it (such as the user's operation on the touch panel 1071 or near the touch panel 1071 using any suitable object or accessory such as a finger, stylus, etc.), and drive the corresponding connection device according to a pre-set program. The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into the touch point coordinates, and then sends it to the processor 110, and can receive and execute the command sent by the processor 110. And/or, the touch panel 1071 can be implemented in various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may further include other input devices 1072. Optionally, the other input devices 1072 may include, but are not limited to, one or more of a physical keyboard, a function key (such as a volume control key, a switch key, etc.), a trackball, a mouse, a joystick, etc., which are not specifically limited here.

Optionally, the touch panel 1071 may cover the display panel 1061. When the touch panel 1071 detects a touch operation on or near it, it is transmitted to the processor 110 to determine the type of the touch event, and then the processor 110 provides a corresponding visual output on the display panel 1061 according to the type of the touch event. Although in FIG. 1 , the touch panel 1071 and the display panel 1061 are used as two independent components to implement the input and output functions of the mobile terminal, in some embodiments, the touch panel 1071 and the display panel 1061 can be integrated to implement the input and output functions of the mobile terminal, which is not limited to the specifics herein.

The memory 109 can be used to store software programs and various data. The memory 109 can mainly include a program storage area and a data storage area. Optionally, the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area can store data created according to the use of the mobile phone (such as audio data, a phone book, etc.), etc. And/or, the memory 109 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.

The processor 110 is the control center of the mobile terminal. It uses various interfaces and lines to connect various parts of the entire mobile terminal. It executes various functions of the mobile terminal and processes data by running or executing software programs and/or modules stored in the memory 109, and calling data stored in the memory 109, so as to monitor the mobile terminal as a whole. The processor 110 may include one or more processing units; preferably, the processor 110 may integrate an application processor and a modem processor. Optionally, the application processor mainly processes the operating system, user interface, and application programs, and the modem processor mainly processes wireless communications. It is understandable that the above-mentioned modem processor may not be integrated into the processor 110.

The mobile terminal 100 may also include a power supply 111 (such as a battery) for supplying power to various components. Preferably, the power supply 111 may be logically connected to the processor 110 via a power management system, thereby implementing functions such as charging, discharging, and power consumption management through the power management system.

Second embodiment

On the basis of the first embodiment of the present application, a second embodiment of the present application is proposed. This embodiment mainly describes a corresponding processing method executed in combination with a maximum number of sending attempts X at a coverage level after the first message fails to be sent.

In the technical solution of this embodiment, for the transmission of CB-Msg3 in the NTN scenario, the terminal device sends the first message based on the second configuration information, thereby optimizing the transmission mechanism of CB-Msg3 in the NTN scenario to reduce or avoid the improvement of the coverage level when the terminal device fails to send continuously due to conflicts.

Optionally, the terminal device starts the first listening window after sending the first message (copy).

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

Optionally, if the terminal device monitors the physical downlink control channel encrypted by the wireless network temporary identifier within the first listening window, and receives a response message corresponding to the first message, and the response information carries a contention resolution identifier that matches the terminal device, the terminal device stops the first listening window and confirms that the contention resolution is successful. At this time, the first message is considered to have been sent successfully.

Optionally, when the first message is sent successfully, if there are remaining copies that have not been sent, the terminal device stops sending the remaining copies.

Optionally, if the first listening window times out and/or the terminal device does not receive a contention resolution identifier that matches the terminal device, it is confirmed that the contention resolution has failed.

Optionally, when all copies of the first message sent by the terminal device fail to resolve contention, the terminal device confirms that the sending of the first message has failed.

Optionally, the failure of the terminal device to send the first message includes a first reason failure and/or a second reason failure.

Optionally, the reason for failure in sending the first message once by the terminal device is determined based on the distribution of reasons for failure in sending all copies of the first message once.

Optionally, if all copies of the first message sent once fail due to the first reason or the number of first reason failures is greater than or equal to the number of second reason failures, then the failure to send the first message is confirmed as the first reason failure.

Optionally, if all copies of the first message sent once fail due to the second reason or the number of second reason failures is greater than or equal to the number of first reason failures, then the failure to send the first message is confirmed to be the second reason failure.

Optionally, in the scenario where the first message fails to be sent, the logic for analyzing the cause of the failure to send may refer to that shown in FIG. 6 .

Optionally, if the terminal device does not receive the physical downlink control channel encrypted with the wireless network temporary identifier and/or the reference signal receiving power is near the coverage level threshold, the terminal device records it as a first reason failure.

Optionally, when the network device detects that the signal strength indication (RSSI) on the corresponding resource is very low, it can be considered that no terminal device is sending data on the corresponding resource, and therefore the physical downlink control channel encrypted with the wireless network temporary identifier will not be sent. At this time, if the terminal device sends data on the corresponding resource but does not receive the physical downlink control channel encrypted with the wireless network temporary identifier, it can be considered that it is caused by coverage reasons.

Optionally, the network device configures a reference signal received power offset, and when the measured reference signal received power is within the coverage level threshold offset, it can be considered that the reference signal received power is near the coverage level threshold.

Optionally, if the terminal device receives a physical downlink control channel encrypted with a wireless network temporary identifier but contention resolution fails and/or a corresponding response message indicates a conflict, the terminal device records it as a second reason failure.

Optionally, if the terminal device receives a physical downlink control channel encrypted with a wireless network temporary identifier but fails to resolve the contention, it indicates that there are other terminal devices sending data on the corresponding resources, which can be considered to be caused by a conflict with other terminal devices.

Optionally, if the terminal device receives a physical downlink control channel encrypted with a wireless network temporary identifier, but the physical downlink control channel indicates a conflict, the terminal device records it as a second reason failure.

Optionally, the network device can determine whether there is a conflict based on the received signal strength indication (RSSI). For example, if the corresponding physical uplink shared channel resolution fails but the signal strength indication RSSI is high, it can be considered that the terminal device sent a conflict on the resource, so the conflict can be indicated through the physical downlink control channel.

Optionally, after the terminal device confirms that the first message fails to be sent, it performs corresponding processing in combination with the maximum number of transmission attempts X of the coverage level, such as continuing to attempt to send the first message at the current coverage level, or determining the main reason for the failure to send the first message (such as coverage reason or conflict reason), and performing different processing according to different failure reasons. This optimizes the transmission mechanism of CB-Msg3 in the NTN scenario to reduce or avoid the need to improve the coverage level when the terminal device fails to send continuously due to conflict reasons.

Optionally, in the scenario where the first message fails to be sent, the process in which the terminal device performs different processing according to different failure reasons can be shown in FIG. 7 .

Optionally, after the first message fails to be sent, if the terminal device attempts to send the first message less than a maximum number of sending attempts X at the current coverage level, the terminal device continues to attempt to send the first message at the current coverage level.

Optionally, after the first message sending fails, if the number of attempts of the terminal device to send the first message is greater than or equal to the maximum number of attempts X for sending the first message at the current coverage level, the terminal device performs a second process.

Optionally, the terminal device performs a second process, including at least one of the following:

If all (copied) transmissions of the first message fail due to the first reason or the number of failures due to the first reason is greater than or equal to the number of failures due to the second reason, the terminal device increases the current coverage level and continues to try to send the first message; optionally, if the current coverage level is already the highest, the terminal device uses a random access procedure (indicating that the transmission failure is mainly due to coverage reasons).

If all (copied) transmissions of the first message fail due to the second reason 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 transmission failure is mainly caused by conflict).

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

After adjusting the first time window, continue to try to send the first message;

After adjusting the number of times the copy is sent, continue to try to send the first message;

Continue to try to send the first message using the random access procedure.

Optionally, when the number of first message sending attempts reaches the maximum number of sending attempts X and or when all first message sending fails due to the second reason or the number of second reason failures is greater than or equal to the number of first reason failures, the terminal device adjusts the first time window and continues to try to send the first message.

Optionally, the terminal device adjusts the first window length according to the window adjustment step.

Optionally, after adjusting the first window length, the terminal device selects N opportunities within the newly adjusted first time window to send N copies of the first message.

Optionally, when the number of window adjustments of the terminal device at the first time is greater than the maximum window adjustment number Y, the terminal device uses a random access process.

Optionally, when the number of window adjustments of the terminal device at the first time is less than or equal to the maximum window adjustment number Y, the terminal device sends a first message using the adjusted window length.

Optionally, when the number of times the first message is sent reaches the maximum number of sending attempts X and/or when all (copied) sending of the first message fails due to the second reason or the number of second reason failures is greater than or equal to the number of first reason failures, the terminal device reduces the number of copy sending times N and continues to try to send the first message.

Optionally, when the current number of copy transmissions of the terminal device is a first value, the terminal device uses a random access process.

Optionally, when the current number of copy and send times of the terminal device is not the first value, the terminal device sends the first message using the reduced or adjusted number of copy and send times.

Optionally, when the number of first message sending times reaches the maximum number of sending attempts X and/or when all (copied) sending of the first message fails due to the second reason or the number of second reason failures is greater than or equal to the number of first reason failures, the terminal device adjusts the number of copied sending times to the first value.

Optionally, the first value is 1.

Optionally, when the current number of times the first message is copied and sent is 1, the terminal device stops using the first message, that is, uses a random access process.

Optionally, when the current number of times the first message is copied and sent is greater than 1, the terminal device reduces the number of times N that the first message is copied and sent to 1, and continues to try to send the first message.

Optionally, when the number of times the first message is sent reaches the maximum number of sending attempts X and/or when all (copied) sending of the first message fails due to the second reason or the number of second reason failures is greater than or equal to the number of first reason failures, the terminal device stops using the first message and directly uses the random access process.

Therefore, when the number of times the first message is sent reaches the maximum number of sending attempts X and/or when all (copied) sending of the first message fails due to the second reason or the number of second reason failures is greater than or equal to the number of first reason failures, the terminal device adjusts the first time window, adjusts the number of copy sending times, adjusts the number of copy sending times to the first value, stops using the first message and directly uses at least one of the random access procedures to continue trying to send the first message, thereby optimizing the DSA processing mechanism, avoiding or reducing the negative gain caused by using DSA when the network load is high or optimizing DSA-related configurations, and supporting the improvement of system performance.

Through the technical solution of this embodiment, the terminal device sends the first message based on the second configuration information, and optimizes the transmission mechanism of CB-Msg3 in the NTN scenario to reduce or avoid the improvement of coverage level when the terminal device fails to send continuously due to conflicts.

Optionally, when the number of times the terminal device sends the first message reaches the maximum number of sending attempts X and/or when all (copied) sending of the first message fails due to the second reason or the number of failures due to the second reason is greater than or equal to the number of failures due to the first reason, the terminal device adjusts the first time window and continues to try to send the first message.

Optionally, the terminal device adjusts the first window length according to the window adjustment step.

Optionally, when the number of window adjustments of the terminal device at the first time is less than or equal to the maximum window adjustment number Y, the terminal device sends a first message using the adjusted window length.

Optionally, when the number of times the terminal device sends the first message reaches the maximum number of sending attempts X and/or when all (copied) sending of the first message fails due to the second reason or the number of second reason failures is greater than or equal to the number of first reason failures, the terminal device reduces the number of copy sending times N and continues to try to send the first message.

Optionally, if the terminal device monitors the physical downlink control channel encrypted by the wireless network temporary identifier within the first listening window, and receives a response message corresponding to the first message, and the response information carries a contention resolution identifier that matches the terminal device, the terminal device stops the first listening window and confirms that the contention resolution is successful. At this time, the first message is considered to have been sent successfully.

Optionally, when the terminal device sends the first message successfully, if there are remaining copies that have not been sent, the terminal device stops sending the remaining copies.

Optionally, if the first listening window of the terminal device times out and/or the terminal device does not receive a contention resolution identifier that matches the terminal device, it is confirmed that the contention resolution has failed.

Optionally, when all copies of the first message sent by the terminal device fail to resolve contention, the terminal device confirms that the sending of the first message has failed.

Optionally, the failure of the terminal device to send the first message includes a first reason failure and/or a second reason failure.

Optionally, the failure to copy and send the first message of the terminal device includes a first reason failure and/or a second reason failure.

Optionally, if all copies of the first message sent by the terminal device at one time fail due to the second reason or the number of second reason failures is greater than or equal to the number of first reason failures, the terminal device confirms that the failure to send the first message is due to the second reason failure.

Optionally, the first reason failure is a failure caused by a coverage reason.

Optionally, the second reason failure is a failure caused by a conflict reason.

Optionally, in the scenario where the first message fails to be sent, the logic for analyzing the cause of the failure to send may refer to that shown in FIG. 6 .

Optionally, if the terminal device does not receive the physical downlink control channel encrypted with the wireless network temporary identifier and/or the reference signal receiving power is near the coverage level threshold, the terminal device records it as a first reason failure.

Optionally, when the network device detects that the signal strength indication (RSSI) on the corresponding resource is very low, it can be considered that no terminal device is sending data on the corresponding resource, and therefore the physical downlink control channel encrypted with the wireless network temporary identifier will not be sent. At this time, if the terminal device sends data on the corresponding resource but does not receive the physical downlink control channel encrypted with the wireless network temporary identifier, it can be considered that it is caused by coverage reasons.

Optionally, if the terminal device receives a physical downlink control channel encrypted with a wireless network temporary identifier but contention resolution fails and/or a corresponding response message indicates a conflict, the terminal device records it as a second reason failure.

Optionally, if the terminal device receives a physical downlink control channel encrypted with a wireless network temporary identifier but fails to resolve the contention, it indicates that there are other terminal devices sending data on the corresponding resources, which is most likely caused by a conflict with other terminal devices.

Optionally, if the terminal device receives a physical downlink control channel encrypted with a wireless network temporary identifier, but the physical downlink control channel indicates a conflict, the terminal device records it as a second reason failure.

Optionally, the network device can determine whether there is a conflict based on the received signal strength indication (RSSI). For example, if the corresponding physical uplink shared channel resolution fails but the signal strength indication RSSI is high, it can be considered that the terminal device sent a conflict on the resource, so the conflict can be indicated through the physical downlink control channel.

Optionally, after the terminal device confirms that the first message fails to be sent, it performs corresponding processing in combination with the maximum number of transmission attempts X of the coverage level, such as continuing to attempt to send the first message at the current coverage level, or determining the main reason for the failure to send the first message (such as coverage reason or conflict reason), and performing different processing according to different failure reasons. This optimizes the transmission mechanism of CB-Msg3 in the NTN scenario to reduce or avoid the need to improve the coverage level when the terminal device fails to send continuously due to conflict reasons.

Optionally, in the scenario where the first message fails to be sent, the process in which the terminal device performs different processing according to different failure reasons can be shown in FIG. 7 .

Optionally, after the terminal device fails to send the first message, if the number of attempts to send the first message by the terminal device is less than the maximum number of attempts X at the current coverage level, the terminal device continues to attempt to send the first message at the current coverage level.

If all (copies) of the first message sent by the terminal device fail due to the first reason or the number of failures due to the first reason is greater than or equal to the number of failures due to the second reason, the terminal device increases the current coverage level and continues to try to send the first message; optionally, if the current coverage level is already the highest, the terminal device uses a random access procedure (indicating that the sending failure is mainly due to coverage reasons).

If all (copied) transmissions of the first message of the terminal device fail due to the second reason or the number of second reason failures is greater than or equal to the number of first reason failures, the terminal device continues to try to send the first message at the current coverage level (indicating that the transmission failure is mainly caused by conflict).

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

The terminal device continues to try to send the first message after adjusting the first time window;

The terminal device continues to try to send the first message after adjusting the number of copy transmissions;

The terminal device continues to attempt to send the first message using the random access procedure.

Optionally, when the number of times the terminal device sends the first message reaches the maximum number of sending attempts X and/or when all (copied) sending of the first message fails due to the second reason or the number of failures due to the second reason is greater than or equal to the number of failures due to the first reason, the terminal device adjusts the first time window and continues to try to send the first message.

Optionally, the terminal device adjusts the first window length according to the window adjustment step.

Optionally, after adjusting the first window length, the terminal device selects N opportunities within the newly adjusted first time window to send N copies of the first message.

Optionally, when the number of window adjustments of the terminal device at the first time is greater than the maximum window adjustment number Y, the terminal device uses a random access process.

Optionally, when the number of window adjustments of the terminal device at the first time is less than or equal to the maximum window adjustment number Y, the terminal device sends a first message using the adjusted window length.

Optionally, when the number of times the terminal device sends the first message reaches the maximum number of sending attempts X and/or when all (copied) sending of the first message fails due to the second reason or the number of second reason failures is greater than or equal to the number of first reason failures, the terminal device reduces the number of copy sending times N and continues to try to send the first message.

Optionally, when the current number of copy transmissions of the terminal device is a first value, the terminal device uses a random access process.

Optionally, when the current number of copy and send times of the terminal device is not the first value, the terminal device sends the first message using the reduced or adjusted number of copy and send times.

Optionally, when the number of times the terminal device sends the first message reaches the maximum number of sending attempts X and/or when all (copied) sending of the first message fails due to the second reason or the number of second reason failures is greater than or equal to the number of first reason failures, the terminal device adjusts the number of copied sending times to the first value.

Optionally, the first value is 1.

Optionally, when the number of times the terminal device copies and sends the first message is 1, the terminal device stops using the first message, that is, uses a random access process.

Optionally, when the current number of times the terminal device copies and sends the first message is greater than 1, the terminal device reduces the number of times N that the terminal device copies and sends the first message to 1, and continues to try to send the first message.

Optionally, when the number of times the terminal device sends the first message reaches the maximum number of sending attempts X and/or when all (copied) sending of the first message fails due to the second reason or the number of second reason failures is greater than or equal to the number of first reason failures, the terminal device stops using the first message and directly uses the random access process.

Therefore, when the number of times the terminal device sends the first message reaches the maximum number of sending attempts X and/or when all (copied) sending of the first message fails due to the second reason or the number of second reason failures is greater than or equal to the number of first reason failures, the terminal device adjusts the first time window, adjusts the number of copy sending times, adjusts the number of copy sending times to the first value, stops using the first message and directly uses at least one of the random access procedures to continue trying to send the first message, thereby optimizing the DSA processing mechanism, avoiding or reducing the negative gain caused by using DSA when the network load is high or optimizing DSA-related configurations, and supporting improving system performance.

Through the technical solution of this embodiment, the terminal device sends the first message based on the second configuration information, and the network device receives the first message, thereby optimizing the transmission mechanism of CB-Msg3 in the NTN scenario to reduce or avoid improving the coverage level when the terminal device fails to send continuously due to conflicts.
