METHOD AND DEVICE OF MIMO WIRELESS COMMUNICATION FOR TRANSMITTING AND DECODING RESOURCE BLOCK STRUCTURE BASED ON DEDICATED REFERENCE SIGNAL MODE

摘要

PROBLEM TO BE SOLVED: To provide an accurate and efficient method for obtaining effective channel response information in explicit signaling, for communicating beam forming information or precoding information from a transmitter to a receiver.SOLUTION: In the transmission and decoding of a resource block (RB) 125 transmitted via a MIMO antenna 115 having a plurality of transmission antennas 115A-115D, effective tradeoff is achieved between correctness and overhead by combining a dedicated reference signal including a single pilot subjected to beam forming or precoding, that is correct but has a large overhead, and a dedicated reference signal including a pilot of a composite subjected to beam forming or precoding, that has a possibility of wrong detection but has a small overhead.
