Description

Technical Field

[0001] 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

[0002] In the existing protocol, the transmission power of PSFCH (Physical Sidelink Feedback Channel) of the terminal device at the same time is the same, which is limited by the maximum transmission power of the terminal device. If too many PSFCHs need to be sent at the same time and exceed the maximum transmission power of the terminal device, the terminal device can only select some PSFCHs with smaller priority values ​​for transmission to ensure that the maximum transmission power of the terminal device is not exceeded.

[0003] During the process of conceiving and implementing the present application, the inventors discovered that in unlicensed spectrum, especially on multiple RB sets (Resource Block sets), the transmission of multiple PSFCHs also depends on the execution result of LBT. Therefore, it cannot be guaranteed that PSFCHs with smaller priority values ​​can be sent, resulting in the terminal device being unable to send as many PSFCHs as possible and / or fully utilize the transmission power resources.

These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of this article, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein can be interpreted as "at the time of" or "when" or "in response to determination". Furthermore, as used in this article, the singular forms "one", "one" and "the" are intended to also include plural forms, unless there is an opposite indication in the context.

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.
