METHOD, DEVICE AND SYSTEM FOR CHANNEL PRE-CODING

摘要

A method, device and system for channel pre-coding are provided, which are used in a communication system of multiple users Multiple Input Multiple Output (MIMO) with Coordinated Multiple Point Transmission and Reception (CoMP). At least two cells provide service for at least one User Equipment (UE) in the system. The method includes: obtaining a time delay difference of the signal of each cell arriving at each UE (S201); compensating a previously obtained channel matrix by the time delay difference of the signal of each cell arriving at each UE (S202); implementing pre-coding processing to the compensated channel matrix (S203).
