Abstract
Conventionally, different HARQ processesand(subframes Tand T) transmit data packets B and D, respectively. One data packet corresponds to one process and is retransmitted as necessary one by one on a process basis, degrading the usage efficiency of frequency and time resources. To solve this problem, downlink data packets B and D, when needed to be retransmitted, are spatially multiplexed in the different HARQ processesand. The data packets are simultaneously retransmitted to the same terminal as process(subframe T).
