Abstract: A method includes: receiving, by a first network control device, CoMP pre-scheduling requests respectively corresponding to at least one edge cell and a first edge cell that is adjacent to the at least one edge cell and that belongs to another CoMP cluster; when determining, based on the CoMP pre-scheduling requests, that the at least one edge cell has a second edge cell meeting a preset condition with the first edge cell, sending an inter-cluster pre-scheduling request to a second network control device; and instructing the second network control device to assign a first coordination cell set including the first edge cell and the second edge cell.

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.
