TRANSMISSION CONTROL METHOD, TRANSMISSION DEVICE, AND RECEPTION DEVICE IN RADIO COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To normally continue communication by maintaining data block matching between retransmission synthesis targets.SOLUTION: In a transmission control method in a radio communication system capable of transmitting a plurality of sets of stream data from a transmission device 1 having a plurality of transmission antennas to a reception device 2 in units of data blocks through a data channel, the transmission device 1 transmits a process number to the reception device 2 through a control channel different from the data channel. On the basis of the received process number, the reception device 2 performs HARQ (hybrid automatic repeat request) in units of the received data blocks, using a process number not conflicting between each stream.
