Abstract: In various embodiments, a first carrier and a second carrier occupying different frequencies can be determined by a terminal device. A working state on the first carrier and a working state on the second carrier can be determined by the terminal device as a first working state, and a second working state, respectively. The first working state indicates the terminal device is capable of sending a first signal including at least one of an uplink data signal and an uplink control signal, and the second working state indicates the terminal device is incapable of sending the first signal. First indication information can be received by the terminal device from a network device. Based on the first indication information, the terminal device can determine that the working state on the first carrier is the second working state, and the working state on the second carrier is the first working state.

Abstract: In a channel state information receiving method, a base station sends first signaling to a terminal device. The first signaling includes sounding reference signal (SRS) information of each of a plurality of subbands. The SRS information of each subband comprises at least one of: a period of an SRS in the subband, a starting position of the SRS in the subband, an offset position of the SRS in the subband, and a port number of the SRS in the subband. The base station receives an SRS in at least one of the plurality of subbands. The base station measures the SRS to obtain channel state information, where the channel state information is obtained by measuring the CSI-RS sent in the at least one subband.
