Abstract: Embodiments of the present invention provide a network listening method and device, where the method includes: determining, by a first device according to a type of a network listening resource, a time-frequency pattern that is of a first sequence and is corresponding to the network listening resource of this type; and then transmitting the first sequence to a second device by using the time-frequency pattern of the first sequence, so that the second device performs network listening according to the first sequence. The time-frequency pattern of the first sequence determined in this process is a time-frequency pattern obtained by transforming a time-frequency pattern of a base sequence, and a network listening signal obtained therefrom, that is, the time-frequency pattern of the first sequence, is simple, which can achieve a purpose of reducing complexity of generating a network listening signal and computational complexity of parsing a network listening signal.

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.
