Abstract

In the technical solution of the present application, a transmission terminal determines transmission beams on the basis of priorities of first channels, and uses the transmission beams to transmit the first channels, thus solving the problem that when a terminal device needs to synchronously transmit a plurality of PSFCHs, PSFCH transmission beam conflicts are caused due to the plurality of PSFCHs using different beams.

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 protocol, in NR (New Radio) sidelink communication, multiple PSFCHs (Physical Sidelink Feedback Channel) can be sent simultaneously.

In the process of conceiving and implementing this application, the inventors found that there are at least the following problems: In R16/17/18NR sidelink communications, these transmissions all use omnidirectional beams. When sidelink communications occur at high frequencies, PSFCH transmissions use directional beams, and directional beams are trained separately for each sidelink unicast session. If a terminal device supports multiple sidelink unicast sessions, the PSFCH training beams of a pair of terminal devices in different sidelink unicast sessions may be different, and the capabilities of the terminal device may be limited. Therefore, the terminal device can only support synchronous transmission based on a single beam, and cannot support synchronous transmission of multiple beams. As described above, the current technical problem that needs to be solved is: when a terminal device needs to send multiple PSFCHs synchronously, the use of different beams by multiple PSFCHs will result in a conflict in the PSFCH transmission beams.

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

Please refer to FIG. 1, 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: an RF (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 FIG. 1 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.

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 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 a telephone call mode, a recording mode, a voice recognition mode, and other operating modes, 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 telephone 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.

In R16/17/18NR sidelink communications, the transmitting terminal uses an omnidirectional beam to send multiple PSFCHs. When sidelink communications occur at high frequencies, PSFCH transmission uses a directional beam, which is trained separately for each sidelink unicast session. If a terminal device supports multiple sidelink unicast sessions, the PSFCH training beams for a pair of terminal devices in different sidelink unicast sessions may be different, and the capabilities of the terminal device may be limited. Therefore, the terminal device can only support synchronous transmission based on a single beam, and cannot support synchronous transmission of multiple beams. When a terminal device needs to send multiple PSFCHs synchronously, the use of different beams by multiple PSFCHs will cause conflicts in the PSFCH transmission beams, as shown in Figure 5.

Based on this, an embodiment of the present application proposes a solution, whereby the transmitting terminal determines the transmitting beam according to the priority of the first channel, and uses the transmitting beam to send the first channel. This can solve the problem that when the terminal device needs to send multiple PSFCHs synchronously, multiple PSFCHs use different beams, which will cause PSFCH transmission beam conflicts.
