Wireless communication method for a MU-MIMO system, wireless communication terminal for communicating with a base station in a MU-MIMO system, and base station for communicating with wireless communication terminals in a MU-MIMO system

摘要

A wireless communication method, a terminal and a base station are provided. The method includes the step of transmitting a plurality of best companion pre-coding matrix indexs (BCIs) and corresponding delta channel quality indicators (ΔCQIs) from the terminal to the base station, wherein the period of frames for transmitting the plurality of BCIs is larger than the period of frames for transmitting a single BCI. The method, terminal and base station according to the present disclosure can greatly increase scheduling flexibility at base station side and improve MU-MIMO performance without increasing feedback overhead of channels.
