Abstract: A reference signal transmission method and apparatus are provided. The method includes: receiving, by a first terminal, uplink reference signal configuration information from a base station, wherein the uplink reference signal configuration information comprises configuration information of a first-type reference signal and configuration information of a second-type reference signal that the first terminal needs to send; and sending, by the first terminal, a first-type reference signal and a second-type reference signal to the base station based on the uplink reference signal configuration information. The method can be applied for V2X (vehicle to X), and/or, sidelink transmission, and/or, D2D (device to device) communication.

Abstract: Embodiments of this application provide a communication processing method. A time domain location of a time domain resource configuration that is in a first wireless communications system and that is aligned with a time domain resource configuration in a second wireless communications system is determined based on a time offset, and a terminal performs data transmission with the first wireless communications system at the determined time domain location. In this way, interference with the second communications system is avoided.

Abstract: The present invention relates to the field of wireless communications, and in particular, to a transmit power control technology in a wireless communications system. In a transmit power control method, user equipment performs transmit power compensation on subframes in different subframe sets by using different power compensation amounts, and sends data in the subframes by using uplink transmit powers on which the transmit power compensation has been performed. According to the solution provided in this application, smoothness of a signal-to-noise ratio of each uplink subframe can be ensured when a full-duplex technology is applied, and reception performance of the uplink subframe can further be ensured without causing excessively large signaling overheads.
