WIRELESS BASE STATION DEVICE USING COLLABORATIVE HARQ TRANSMISSION SYSTEM, WIRELESS TERMINAL DEVICE, WIRELESS COMMUNICATION SYSTEM AND WIRELESS COMMUNICATION METHOD Russian patent published in 2016 - IPC H04W4/00

Abstract RU 2584479 C1

FIELD: antenna.

SUBSTANCE: invention relates to collaborative transmission system technology with a distributed antenna. In a transmitting device at serving eNB side, a first packet transmitting unit carries out an operation for packet transmission of retransmitted data. On other side, in a transmitting device on side of collaborative transmission of eNB, a module for transmitting a second packet performs transmission of a new data packet corresponding to data transmitted from serving eNB by packet transmission module. Control information on transmission to UE by serving eNB and combined eNB is transmitted using only PUCCH from UE on serving eNB and PDCCH from serving eNB to UE. Serving eNB and combined eNB perform transmission of a new data packet and data transmission control information, etc, through an X2 interface.

EFFECT: technical result is efficiency of HARQ process in collaborative transmission system.
