Abstract
A method for guaranteeing channel phase continuity of pre-coded RB groups, a base station and a computer-readable storage medium are described. The method includes that: a base station implements a channel estimation through a Sounding Reference Signal (SRS) measurement to obtain an uplink channel and obtains a corresponding downlink channel based on reciprocity of uplink and downlink channels; the base station calculates a weight phase correction factor based on the obtained downlink channel and corrects a pre-coding weight with the weight phase correction factor; and the base station pre-codes data according to the corrected pre-coding weight and sends the pre-coded data.
