Abstract

The invention relates to a communication method and device, which can be applied to the Internet of Vehicles, such as V2X, LTEV and V2V, or can be applied to the fields of intelligent driving, intelligent network connection vehicles and the like. A terminal device determines an initial transmission power of each of the at least two sidewalk signals. The sum of the initial sending powers of the atleast two sidewalk signals is greater than the maximum sending power of the terminal device, the terminal device determines the first sending power of the ith sidewalk signal in the at least two sidewalk signals according to the priorities of the at least two sidewalk signals, i is an integer from 1 to N, and N is the number of the at least two sidewalk signals. The terminal device transmits the i-th sidelink signal on the i-th sidelink of the at least two sidelinks in accordance with the first transmission power of the i-th sidelink signal.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and device. Background technique [0002] Uplink power control in a wireless communication system is very important. Through the uplink power control, the terminal equipment can not only ensure the quality of uplink data, but also reduce the interference to the system and other users as much as possible, and prolong the service time of the battery of the terminal equipment. Through uplink power control, the base station can make uplink transmission adapt to different wireless transmission environments, including path loss, shadow, fast fading, and interference from other terminal equipment in and between cells. [0003] For example, for an uplink control channel or an uplink data channel, there are currently corresponding formulas for calculating uplink transmission power, so as to realize uplink power control. [0004] However, at pre...
