Sending and receiving method of feedback information in the multiplex antenna system which supports the multi-user and the feedback system which supports this

摘要

As for this invention, the method sending and receiving of doing feedback information in the multiplex antenna system of the closed loop system which supports the multi-user and the feedback system which supports that are offered. Plural feedback protocol scenarios are defined beforehand on the basis of the communication environment which exerts influence on constitution of feedback information. Feedback information this is transmitted with the feedback protocol scenario which is decided by communication environment. Feedback information this consists of the information which is required by communication environment. Selective figure Figure 3
