APPARATUS AND METHDO FOR COLLABORATE HYBRID AUTOMATIC REPEAT REQEUST IN BROADBAND WIRELESS COMMUNICATION SYSTEM WITH RELAY STATION

摘要

Repeater of the present invention use because broadband wireless communication system middle cooperation HARQ (cooperation mixed automatic repeat request) to about that, transmitting terminal, one repeater and a distance estimations distance estimations are used for distance estimations distance estimations, estimate repeater and is used to determine whether that cooperation HARQ is executed apart from using a controller, when it is determined executing above-mentioned cooperative society's complex relays more, it is requested when from the transfer of receiving end, repeater and imaginary number form a multi-antenna group and provide the utilization standard for being used for suitably cooperating HARQ according to the re-transmission grouping of a multi-antenna signal processing, including transmission unit for sending, position based on repeater to and by include using virtual multiple antenna environment repeater and transmitting terminal transmitting antenna, the cooperation composite performance for the automatic re-transmission scheme that it can be improved. ;Repeater, cooperation HARQ (mixed automatic repeat request cooperation), energy consumption, multiple antenna
