Problems solved by technology

[0004] Although the open-loop power control in the side-link communication can be realized through the above method, the open-loop power control in the side-link communication cannot guarantee that the information receiving terminal in the side-link communication is always in a good information receiving effect In this way, the accuracy of power control in sidelink communication is poor, and power is wasted, and the overall performance of the communication system is low. Therefore, in 5G and subsequent evolved wireless network communications, it is necessary to provide more optimized or more reliable Power Control Scheme for Link Communication

Abstract

The embodiment of the present application discloses a sidelink power control method and terminal equipment. The method is applied to the terminal equipment, including: sending information to the first terminal equipment in the sidelink communication, so that the first terminal equipment Generate success control indication information according to the reception of the information, and receive the power control indication information from the first terminal device; determine the information transmission power of the terminal device in the side link communication according to the power control indication information. Utilizing the embodiment of this application, the terminal device can use the power control indication information in the side link communication to perform closed-loop power control, and further adjust the transmission power of the information sending terminal in the side link communication, so that the first terminal device It can always ensure that the information or signal sent by the information sending terminal is received with a better reception effect, thereby reducing power waste and improving the overall performance of the communication system.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a sidelink power control method and terminal equipment. Background technique [0002] In 5G and subsequent evolved wireless network communications, sidelink (sidelink) communication usually has a power control mechanism. Through the power control mechanism, the transmission power of the information sending terminal in sidelink communication can be adjusted so that the sidelink The information receiving terminal in communication always maintains a good receiving effect. [0003] Typically, the power control mechanism for sidelink communication is implemented through an open-loop power control mechanism in sidelink communication. Currently, the open-loop power control in sidelink communication can be implemented based on the open-loop power control method in Long Term Evolution (LTE), that is, the path loss (ie, Pathloss) between the terminal device and the ne...
