Abstract: Embodiments of this application provide a signal transmission method and apparatus. The method includes: receiving, by a terminal device, configuration information sent by a network device, where the configuration information is used to instruct the terminal device to send a reference signal, and a resource used to transmit the reference signal is determined based on a public cell identity of a cell to which the terminal device belongs; and sending, by the terminal device, the reference signal based on the configuration information by using the resource. According to the signal transmission method and apparatus in the embodiments of this application, an existing reference signal can be used to perform interference/channel measurement between terminal devices, so that a terminal device on a receiving side can distinguish between interference cells while reference signal utilization is improved.

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.
