WIRELESS COMMUNICATION METHOD IN MULTIANTENNA COMMUNICATION SYSTEM

摘要

A wireless communication method in which use of the HERQ technique brings about an improved throughput of data transmission. In this method, if the number of retransmissions n is equal or below an upper limit value (ST404: NO), a transmission mode k is computed for k=n mod 4 at the transmission side (ST405), sub-streams are grouped into combinations of sub-streams according to the channel status fed back from the transmission side if k=1 (ST 407), time-space block coding of the data of each group is performed (ST 408), the coded data is allocated to the corresponding antenna and retransmitted (ST409), and the retransmitted data is combined with the previously transmitted data and time-space block decoding is performed (ST410).
