Transmission controlling method, sender apparatus and receiver apparatus for wireless communication system
A wireless communication system including a sender apparatus having a plurality of transmitting antennas that transmits a plurality of data blocks; and a receiver apparatus that receives the plurality of data blocks, wherein the sender apparatus transmits a process number via a control channel different from a data channel to the receiver apparatus, and wherein the receiver apparatus performs HARQ processing of received data blocks based on the received process number which prevents the data blocks from competing.
1. A wireless communication system comprising:
a sender apparatus having a plurality of transmitting antennas that transmits a plurality of data blocks; and
a receiver apparatus that receives the plurality of data blocks, wherein the sender apparatus transmits a process number via a control channel different from a data channel to the receiver apparatus,
the process number is based on a predetermined rule shared between the sender apparatus and the receiver apparatus, and
the receiver apparatus performs HARQ processing of received data blocks based on the received process number which is not competitive between the data blocks by the rule.
2. A wireless communication method for a wireless communication system including a sender apparatus having a plurality of transmitting antennas that transmits a plurality of data blocks; and a receiver apparatus that receives the plurality of data blocks, the wireless communication method comprising:
on the sender apparatus,
transmitting a process number via a control channel different from a data channel to the receiver apparatus, the process number being based on a predetermined rule shared between the sender apparatus and the receiver apparatus; and
on the receiver apparatus,
performing HARQ processing of received data blocks based on the received process number which is not competitive between the data blocks by the rule.
3. The wireless communication system according to claim 1 , wherein
the rule is defined in such a manner that the process number for each of the plurality of data blocks is determined to have an offset between a process number for a data block transmitted over a first transmission system and a process number for a data block transmitted over a second transmission system, the offset being determined depending on the number of HARQ processes.
4. The wireless communication method according to claim 2 , wherein
the rule is defined in such a manner that the process number for each of the plurality of data blocks is determined to have an offset between a process number for a data block transmitted over a first transmission system and a process number for a data block transmitted over a second transmission system, the offset being determined depending on the number of HARQ processes.
