The disclosure relates to a method and a device therefor, wherein the method is applied to CA between base stations including multiple base stations connected through non-ideal backhaul, has a master RLC pre-assign an RLC SN to a PDCP PDU and transmit the PDCP PDU to a slave RLC of each base station, and has the master RLC take full responsibility for ARQ retransmission management, thereby enabling more efficient use of a network resource and a reduction in the time spent for a retransmission.

Packet generation and distribution method for supporting carrier aggregation between base stations, and device therefor

Provided are a transmitting apparatus and a transmitting method in a multiple input multiple output system. A power allocation controller includes a block Tomlinson-Harashima precoder (BTHP) that precodes and outputs data to be transmitted to each user in a nonlinear scheme. The BTHP removes and outputs inference signals from data for each user based on the channel information that is fed back from the users. The data for each user output from the BTHP are allocated with power by the power allocation controller. The power allocation controller calculates power allocation parameters so that receiving minimum distances at receiving ends for each user that receive data through the MIMO antennas are the same, and allocates the calculated parameters to data for each user.
