Abstract

The present invention provides a CSI processing and measurement pilot resource transmission method and device, wherein the processing method includes: a terminal receives a first measurement pilot resource, and obtains a first CSI according to the first measurement pilot resource ; the terminal receives the second measurement pilot resource, and obtains the second CSI according to the second measurement pilot resource and the first CSI. The above technical solution solves the problem that in the related art, the terminal independently measures and calculates the received two measurement pilot resources sent by the base station, and the obtained two RI values ​​may be different, so that the base station cannot The CSI fed back by the terminal solves the problem of accurate scheduling and data transmission, thereby ensuring that the terminal can send correct channel state information to the base station.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a method and device for processing CSI and measuring pilot resources. Background technique [0002] Multi-antenna technology is a key technology for improving the robustness of wireless links or improving spectral efficiency in the field of wireless communication. One of the principles of multi-antenna technology is to use some characteristics of the channel to form multi-layer transmission that matches the characteristics of the channel. The radiation direction of the signal is very targeted, which can effectively improve the system performance and achieve significant performance without increasing bandwidth and power. Performance improvements. How to obtain channel state information (CSI) matching the channel (eg, precoding matrix, channel rank, channel quality information) is very important in multi-antenna technology, which largely determines the multi-antenna The...
