Abstract

The invention provides a method and a device for processing a reference signal, and relates to the technical field of communication. The problem that the data cannot be transmitted effectively and network performance is reduced is solved, wherein the problem is caused by unsuitable processing of the reference signal. The method for processing the reference signal comprises the following steps: receiving at least two channel state indication reference signal (CSI-RS) configurations sent by a receiving station, wherein the at least two CSI-RS configurations are respectively comprise corresponding CSI-RS resource information, and CSI-RS power information of the CSI-RS configurations; confirming corresponding feedback information corresponding to the CSI-RS configurations according to the CSI-RS power information; and sending feedback information. The method and the device for processing the reference signal are applied to data transmission in a wireless communication system.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for processing a reference signal. Background technique [0002] When the base station communicates with the UE, the base station allocates resources for each channel according to information fed back by the UE such as CSI (Channel State Information) and CQI (Channel Quality Indicator, Channel Quality Indicator), that is, the base station selects appropriate channel resources To transmit data to the UE, it is particularly important for the base station to obtain accurate feedback information. [0003] In order for the UE to determine the feedback information, the base station sends at least two CSI-RS (Channel-State Information-Reference Signal, channel state information reference signal) configurations and one CSI-RS configuration for each UE (User Equipment, user equipment) under its jurisdiction. The power information, the CSI-RS power infor...
