Transmission controlling method, sender apparatus and receiver apparatus for wireless communication system
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, the transmission controlling method includes on the sender apparatus, sending process information which is not competitive between data blocks to the receiver apparatus with a control channel; and sending the data block to the receiver apparatus; and on the receiver apparatus, receiving the data block and the process information from the sender apparatus.
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, the transmission controlling method comprising:
on the sender apparatus,
sending process information to the receiver apparatus via a control channel different from a data channel, wherein the process information is based on a predetermined rule shared between the sender apparatus and the receiver apparatus, by which the process information is not competitive between the data blocks; and
sending the data blocks to the receiver apparatus; and
on the receiver apparatus,
receiving the data blocks and the process information from the sender apparatus.
2. The transmission controlling method according to claim 1 , wherein the sender apparatus sends information including an antenna identifier relating to any of the sending antennas which sends the data blocks as the process information via the control channel.
3. The transmission controlling method according to claim 1 , wherein
the rule is defined in such a manner that a value of the process information for each of the data blocks is determined to have an offset between a value of the process information for a data block transmitted over a first transmission system and a value of the process information for a data block transmitted over a second transmission system, the offset being determined depending on the number of HARQ processes.
