Abstract: Embodiments of the present invention disclose a base station, user equipment (UE), and a carrier scheduling indication method to resolve a problem that signaling overheads are relatively large. An embodiment method includes generating, by a processing unit, a carrier assignment indication (CAI) field of a current scheduled carrier according to scheduling statuses of all configured carriers, where the CAI field is used to indicate a total quantity of scheduled carriers in all the configured carriers and an accumulative index value M of the current scheduled carrier, and M represents that the current scheduled carrier is the Mth scheduled carrier from the 1st configured carrier to the current scheduled carrier; and sending, by a sending unit, downlink control information digital control information (DCI), by carrying the CAI field generated by the processing unit to the DCI, to UE by using the current scheduled carrier.

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: This application provides a data communication method, a terminal, and a base station. In one embodiment, the terminal receives a first demodulation reference signal based on a first physical resource block index. The first physical resource block index is determined based on a first location in frequency domain, and the first demodulation reference signal is used to demodulate a data channel on which system information is located. The terminal sends and/or receives a second demodulation reference signal based on a second physical resource block index. The second physical resource block index is determined based on a second location in frequency domain, and the second demodulation reference signal is used to demodulate a data channel other than the data channel on which the system information is located.
