MIMO TRANSMITTING APPARATUS, MIMO RECEIVING APPARATUS, AND RETRANSMITTING METHOD. |
摘要 |
<p>A MIMO transmitting apparatus that achieves a flexible control in accordance with variation of a propagation environment to reduce the number of retransmissions. A buffer (104) temporarily stores transport bits, which have been interleaved, in preparation for retransmission. An intra-code-word interleaver (105) performs an interleave process by all of the bits included in the symbols to be simultaneously transmitted from a plurality of transmitting antennas. When performing an intra-code-word interleave process, the intra-code-word interleaver (105) performs the interleave process in accordance with an interleave pattern notified from an interleave pattern table (107). A counter (106) counts retransmission requests, and outputs the number of retransmissions to the interleave pattern table (107). The interleave pattern table (107) stores interleave patterns to be used for intra-code-word interleave process for the respective numbers of retransmissions, and notifies the intra-code-word interleaver (105) of an interleave pattern in accordance with a number of retransmissions.</p> |
