Abstract
The present disclosure relates to methods for obtaining channel state information (CSI), apparatus, and computer storage medium. One example method includes allocating, by a network device to a terminal device according to a preset rule, a transmission resource for transmitting a sounding reference signal (SRS) in a cell to which the terminal device belongs. Transmission resources for transmitting SRSs in different cells do not overlap at all or partially overlap. The network device receives the SRS transmitted by the terminal device on the allocated transmission resource, and performs channel quality estimation based on the received SRS to obtain CSI.
