Description

Processing method, communication device and storage medium Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a processing method, communication equipment and storage medium. Background Art

[0002] In the existing scenario where PSFCHs (Physical Sidelink Feedback Channels) are simultaneously received and / or transmitted, which PSFCHs can be transmitted or received is determined based on the priority ranking of the PSFCHs.

[0003] However, during the process of conceiving and implementing this application, the inventors discovered that in unlicensed spectrum, especially on multiple RB sets (resource sets), the transmission and reception of multiple PSFCHs also depends on the results of LBT, so there is no guarantee that PSFCHs with high priority can be sent or received.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Technical Solutions

[0005] The main purpose of this application is to provide a processing method, a communication device and a storage medium, which can send or receive PSFCH by using the priority value of PSFCH and / or the LBT execution result, so that the terminal device can send PSFCH as much as possible.

[0006] This application proposes a processing method that can be applied to a terminal device (such as a mobile phone), comprising the steps of:

[0007] S10: Send or receive PSFCH according to the priority value of PSFCH and / or the LBT execution result.

[0008] Optionally, the step S10 includes:

[0009] The PSFCH is sent or received according to the target PSFCH corresponding to the minimum priority value among at least two PSFCH priority values, and / or the LBT execution result.

[0010] Optionally, step S10 includes at least one of the following:

[0011] If at least one of the target PSFCHs is a receive PSFCH, the target PSFCH is received;

[0013] Optionally, the sending or receiving of the PSFCH according to the LBT execution result includes at least one of the following:

[0014] If at least one PSFCH in the target PSFCH LBT is successfully executed, the PSFCH in which the LBT is successfully executed is sent;

[0015] If the LBT execution of all target PSFCHs fails, a second smallest priority value among the priority values ​​of the at least two PSFCHs is selected, and step S10 is repeated until the PSFCH that needs to be sent or received is determined.

[0016] Optionally, the method further comprises at least one of the following:

[0017] The at least two PSFCHs are a receive PSFCH and / or a first transmit PSFCH;

[0018] Determine, according to an LBT execution result of at least one subband distributed by at least two PSFCHs, a first transmit PSFCH distributed on a subband on which LBT execution is successful;

[0019] At least one PSFCH is determined according to the minimum priority value in the received PSFCH and / or the first transmitted PSFCH, and the at least one PSFCH is transmitted or received.

[0020] Optionally, the method further includes:

[0021] If the terminal device is to transmit the PSFCH in a PSFCH transmission opportunity, the terminal device will transmit the first transmitted PSFCH corresponding to the minimum priority value indicated in all SCI formats 1-A related to the PSFCH transmission.

[0022] Optionally, the method further comprises at least one of the following:

[0027] The terminal device receives the first group of SCI format 1-A and the PSSCH scheduled by it, and the sending PSFCH carries feedback information related to the PSSCH;

[0028] The terminal device sends the second group of SCI format 1-A and the PSSCH scheduled therefor, and the received PSFCH carries PSSCH-related feedback information.

[0029] Optionally, the method further comprises at least one of the following:

[0030] For PSFCH transmission or reception with HARQ-ACK information, the priority value of the PSFCH is equal to the priority value indicated by SCI format 1-A associated with the PSFCH;

[0031] The priority value indicated by the SCI format 1-A associated with the PSFCH is the priority value of the PSSCH scheduled by the SCI format 1-A;

[0032] For PSFCH transmissions with contention information, the priority value of the PSFCH is equal to the minimum priority value determined for the contention resource by the corresponding SCI format 1-A;

It will be understood by those skilled in the art that, in addition to components specifically used for mobile purposes, the configuration according to the embodiments of the present application can also be applied to fixed-type terminals.

[0061] Please refer to Figure 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 components such as 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 understand that the mobile terminal structure shown in Figure 1 does not limit the mobile terminal. The mobile terminal may include more or fewer components than shown, or may combine certain components, or arrange the components differently.

[0062] The following is a detailed introduction to the various components of the mobile terminal in conjunction with Figure 1:

[0063] The RF unit 101 can be used to send and receive information or receive signals during calls. Specifically, it receives downlink information from the base station and transmits it to the processor 110 for processing. It also transmits uplink data to the base station. Typically, the RF unit 101 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, and more. Furthermore, the RF unit 101 can communicate with the network and other devices via wireless communication. The above-mentioned wireless communications can 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) and 5G, etc.

[0064] WiFi is a short-range wireless transmission technology. A mobile terminal, through WiFi module 102, enables users to send and receive emails, browse web pages, and access streaming media, providing wireless broadband Internet access. Although FIG1 illustrates WiFi module 102, it is understood that it is not a required component of the mobile terminal and can be omitted as needed without altering the essence of the invention.

[0065] The audio output unit 103 can convert 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, or the like. Furthermore, the audio output unit 103 can also provide audio output related to a specific function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output unit 103 may include a speaker, a buzzer, or the like.

[0066] The A / V input unit 104 is used to receive audio or video signals. The A / V input unit 104 may include a graphics processing unit (GPU) 1041 and a microphone 1042. The GPU 1041 processes image data of still images or videos captured by an image capture device (e.g., a camera) in video capture mode or image capture mode. The processed image frames may be displayed on the display unit 106. The image frames processed by the GPU 1041 may be stored in the memory 109 (or other storage medium) or transmitted via the RF unit 101 or the WiFi module 102. The microphone 1042 may receive sound (audio data) in operating modes such as a phone call mode, a recording mode, and a voice recognition mode, and may process such sound into audio data. In the phone call mode, the processed audio (voice) data may be converted into a format that can be transmitted to a mobile communication base station via the RF unit 101. The microphone 1042 may implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.

[0067] 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 recognize 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 in the mobile phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be described here.

[0068] The display unit 106 is used to display information input by the user or information provided to the user. The display unit 106 may include a display panel 1061, which may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like.

[0069] The user input unit 107 can be used to receive input digital or character information, and to generate key signal input related to the user settings and function control of the mobile terminal. 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 user touch operations on or near it (such as operations performed by the user using a finger, stylus, or any other suitable object or accessory on or near the touch panel 1071) 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 direction and detects the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device and converts it into touch point coordinates, which are then sent to the processor 110. It can also receive commands sent by the processor 110 and execute them. In addition, the touch panel 1071 can be implemented using 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, function keys (such as volume control keys, power keys, etc.), a trackball, a mouse, a joystick, etc., and the specifics are not limited here.

[0070] Optionally, the touch panel 1071 may overlay the display panel 1061. When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of touch event. The processor 110 then provides a corresponding visual output on the display panel 1061 based on the type of touch event. Although in FIG1 , the touch panel 1071 and the display panel 1061 are shown as two separate components to implement the input and output functions of the mobile terminal, in some embodiments, the touch panel 1071 and the display panel 1061 may be integrated to implement the input and output functions of the mobile terminal, which is not limited to this specific embodiment.

[0071] The interface unit 108 serves as an interface through which at least one external device can be connected to the mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device with an identification module, an audio input / output (I / O) port, a video I / O port, a headphone port, etc. The interface unit 108 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal 100 and an external device.

[0072] Memory 109 can be used to store software programs and various data. Memory 109 may primarily include a program storage area and a data storage area. Optionally, the program storage area may store an operating system and at least one application required for a function (such as a sound playback function or an image playback function); the data storage area may store data generated based on the use of the mobile phone (such as audio data, a phone book, etc.). Furthermore, memory 109 may include high-speed random access memory and non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0073] Processor 110 is the control center of the mobile terminal, connecting all components of the mobile terminal using various interfaces and circuits. By running or executing software programs and / or modules stored in memory 109 and accessing data stored in memory 109, it executes various functions of the mobile terminal and processes data, thereby providing overall monitoring of the mobile terminal. Processor 110 may include one or more processing units; preferably, processor 110 may integrate an application processor and a modem processor. Optionally, the application processor primarily handles the operating system, user interface, and application programs, while the modem processor primarily handles wireless communications. It is understood that the modem processor may not be integrated into processor 110.

[0074] 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 through a power management system, thereby enabling the power management system to manage functions such as charging, discharging, and power consumption.
