Title:
COEFFICIENT INDICATION METHOD AND APPARATUS, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/020812
Kind Code:
A1
Abstract:
The present application relates to the field of mobile communications. Disclosed are a coefficient indication method and apparatus, and a storage medium. The method comprises: a terminal receiving configuration information sent by a network device, wherein the configuration information is used for configuring codebook parameters of a plurality of transmission reception point (TRP) groups, and each TRP group comprises at least one TRP; determining first indication information according to the configuration information, wherein the first indication information is used for indicating the position of a non-zero coefficient in a combination coefficient, the combination coefficient is a coefficient determined by the terminal according to the codebook parameters of the plurality of TRP groups, and the combination coefficient is used for the network device to perform precoding calculation; and sending the first indication information to the network device. The present application expands the manner in which a terminal reports the position of a non-zero coefficient in a combination coefficient, and is used for a network device to obtain non-zero coefficient position information corresponding to a plurality of TRPs, thereby ensuring the reliability of communication between the terminal and the network device.
