Abstract

Provided in an embodiment of the present application are an uplink channel transmission method, a terminal, a base station and a storage medium. The method comprises the following steps: after determining that a precoding matrix is used to switch diversity to send an uplink channel, dividing resources for transmitting the uplink channel into at least two resource groups, each resource group is mapped to an antenna set through pre-coding based on the pre-coding matrix; the antenna set comprises a plurality of physical antennas or a plurality of antenna ports; and sending the uplink channel in a diversity manner through the antenna set. According to the embodiment of the invention, the resources for transmitting the uplink channel are divided into at least two resource groups, each resource group is mapped to the antenna set through precoding, and the uplink channel is sent through the antenna set and diversity, so that the transmission performance of the uplink channel is improved. For cell edge users, when the channel condition is poor, the transmission performance of the uplink channel is still good, and the coverage requirement is met.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to an uplink channel transmission method, a terminal, a base station, and a storage medium. Background technique [0002] The uplink channel is used for the terminal to send information to the base station, such as the uplink control channel is used for the terminal to send a scheduling request SR (Scheduling Request), HARQ (Hybrid Automatic Repeat reQuest, hybrid automatic repeat request) feedback, and channel status information CSI (Channel Status Information) and other information. [0003] However, the uplink channel in the existing NR uses a single antenna for transmission. For cell edge users, the transmission performance of the uplink channel is poor when the channel condition is poor, which may not meet the coverage requirements. [0004] Therefore, how to propose a method for improving the transmission performance of the uplink channel has beco...
