Claim 10:
11. A communication apparatus, comprising:
at least one processor; and
one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to perform operations comprising:
allocating, 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, wherein the preset rule includes allocating SRS transmission resources based on cell quantity, wherein transmission resources for transmitting SRSs in different cells do not overlap at all or partially overlap, and wherein the transmission resource comprises a time domain resource, a frequency domain resource, a carrier domain resource, or a code domain resource;
receiving, the SRS transmitted by the terminal device on the allocated transmission resource; and
performing, channel quality estimation based on the received SRS to obtain channel state information (CSI).
