METHOD AND SYSTEM FOR ADAPTATION BETWEEN DIFFERENT CLOSED-LOOP, OPEN-LOOP AND HYBRID TECHNIQUES FOR MULTIPLE ANTENNA SYSTEMS

摘要

A method for the adaptation between the different closed-loop , open loop and a hybrid technique for multi-antenna systems, and system side are full feedback information (full feedback information), a reduced amount of feedback information (reduced quantity feedback information) or no feedback information (no feedback information) as based on the communication medium selected from a plurality of signals to be transmitted over the same time that can be generated may include a transmitting station . The selection can be determined at the transmitting station based on the determined Doppler frequency shift (Doppler shift fequency).
