Abstract:
1. A data transmission method between a first transceiver and a second transceiver, comprising: using more than one antenna for transmitting and receiving a signal at least in one of the first and second transceivers; dividing in the first transceiver the symbols to be transmitted into a set of blocks, the number of blocks in the set being divisible by the number of transmitting antennas; transmitting one block using each antenna; receiving the blocks in the second transceiver using one or more antennas; checking in the second transceiver whether all blocks of the set were received successfully; transmitting an acknowledgement to the first transceiver; and, if the reception of the blocks of the set failed, storing the blocks of the set in memory in the second transceiver; retransmitting the same blocks of the set from the first transceiver in a predetermined format; receiving the retransmitted blocks in the second transceiver using one or more antennas and combining them with the blocks in memory, and selecting the predetermined format so that the blocks in the memory and the retransmitted blocks form space-time block coding.
