WIRELESS BASE STATION DEVICE USING COOPERATIVE HARQ TRANSMISSION SYSTEM, WIRELESS TERMINAL DEVICE, WIRELESS COMMUNICATION SYSTEM AND WIRELESS COMMUNICATION METHOD Russian patent published in 2015 - IPC H04W4/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to the technology of a cooperative transmission system which uses a distributed antenna. In a transmitting device at the serving eNB side, a first packet transmitting unit carries out an operation for packet transmission of retransmitted data. On the other hand, in a transmitting device at a cooperative eNB side, a second packet transmitting unit carries out an operation of transmitting a new data packet corresponding to information transmitted from the serving eNB by a packet transmitting unit. Control information on transmission by the serving eNB and the cooperative eNB to UE is transmitted only through a PUCCH from the UE to the serving eNB and a PDCCH from the serving eNB to the UE. The serving eNB and the cooperative eNB transmit the new data packet and the communication control information or the like through an X2 interface.

EFFECT: efficient HARQ process in a cooperative transmission system.
