Transmission controlling method, sender apparatus and receiver apparatus for wireless communication system

摘要

In a wireless communication system, a sender apparatus sends a data block, for each of a plurality of stream data, with data block identification information, which does not conflict between stream data, annexed, and a reception apparatus performs a re-sending synthesis process for a data block received already and a re-sending data block to which the same data block identification information is individually annexed based on the data block identification information annexed to the received data block. Consequently, also in a case wherein the number of transmission streams between the sender apparatus and the reception apparatus is varied (reduced), the matching property of the data block which is a re-sending synthesis target can be maintained and communication can be continued normally.

主权项

1. A transmission controlling method for a wireless communication system wherein a plurality of data blocks can be transmitted from a sender apparatus having a plurality of sending antennas to a receiver apparatus, wherein:
the sender apparatus associates, for each of the plurality of data blocks, data block identification information with the data block and sends the resulting data block to the receiver apparatus, wherein the data block identification information is based on a predetermined rule shared between the sender apparatus and the receiver apparatus, by which the data block identification information is not competitive between the data blocks; and the receiver apparatus carries out, based on the data block identification information associated with the received data block from the sender apparatus, a combining process for the data block received already and a re-sent data block with both of which the same data block identification information is associated.
