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.

Abstract: Example wireless communication methods and apparatus are described. In one example method, a relay device receives a first signal sent by a first device, where the first signal carries a plurality of bits. The relay device decodes the first signal to determine first information corresponding to each of a plurality of first bits. The first information corresponding to each first bit is determined based on a probability that the first bit is 1 and a probability that the first bit is 0. The relay device sends the first information in a second signal to a second device, so that the second device can use the first information to decode the first signal.
