Information Processing Method, Base Station, and User Equipment

摘要

Embodiments provide an information processing method, a base station, and user equipment. The method includes determining multiple subband groups, where the multiple subband groups are obtained by dividing multiple physical resource blocks corresponding to resource elements (REs) originally occupied by a CSI-RS, and each subband group in the multiple subband groups includes at least one subband. The method also includes determining a reference signal corresponding to each subband group in the multiple subband groups, where the reference signal corresponding to each subband group is generated by performing a precoding operation on the CSI-RS originally carried in first bearer REs in each subband in each subband group. Additionally, the method includes transmitting, by using the first bearer REs in each subband group in the multiple subband groups, the reference signal corresponding to each subband group.

1. A base station comprising:
a processor; and a non-transitory computer readable storage medium storing a program for execution by the processor, the program including instructions to:
determine multiple subband groups, wherein the multiple subband groups are obtained by dividing multiple physical resource blocks corresponding to resource elements (REs) originally occupied by a channel state information-reference signal (CSI-RS), wherein each subband group in the multiple subband groups comprises at least one subband;determine a reference signal corresponding to each subband group in the multiple subband groups, comprising performing a precoding operation on the CSI-RS originally carried in first bearer REs in each subband in each subband group, wherein different precoding is used in response to precoding operations being performed on the CSI-RS originally carried in the first bearer REs in different subband groups; and transmit, using the first bearer REs in each subband group in the multiple subband groups, the reference signal corresponding to each subband group.
