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.

Method for obtaining channel state information, apparatus, and computer storage medium

The present disclosure relates to example methods and communication apparatus. In one example method a base station divides a coverage area of a first antenna into at least two cells and performs weighted processing on data carried on time-frequency resources of the at least two cells to map the data carried on the time-frequency resources of the at least two cells to a channel of the first antenna. The base station combines the data carried on the time-frequency resources of the at least two cells, and either transmits at least two directional beams by using the first antenna, where the at least two directional beams have different directions, and wherein the at least two directional beams are in a one-to-one correspondence with the at least two cells, or the base station transmits one directional beam by using the first antenna.
