Title:
UPLINK CHANNEL TRANSMISSION METHOD, TERMINAL, BASE STATION, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/028138
Kind Code:
A1
Abstract:
Provided in the embodiments of the present disclosure are an uplink channel transmission method, a terminal, a base station, and a storage medium, the method comprising: after determining to use a precoding matrix to switch diversified transmission of an uplink channel, dividing resources for transmitting the uplink channel into at least two resource groups, and, on the basis of the precoding matrix, mapping each resource group to an antenna set by means of precoding, the antenna sets comprising a plurality of physical antennas or a plurality of antenna ports; and perform diversified transmission of the uplink channel by means of the antenna sets. The embodiments of the present disclosure improve the transmission performance of an uplink channel by dividing the resources for transmitting the uplink channel into at least two resource groups, mapping each resource group to an antenna set by means of precoding, and performing diversified transmission of the uplink channel by means of the antenna sets. For cell edge users, the transmission performance of an uplink channel is still good when the channel conditions are poor, thus meeting coverage needs.
