Abstract: The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate than a 4th generation (4G) communication system such as long term evolution (LTE). According to various embodiments of the present disclosure, in a wireless communication system, a base station comprises: at least one transceiver, and at least one processor coupled to the at least one transceiver. The at least one processor may be configured to: control the at least one transceiver to transmit first data based on a first hybrid automatic request (HARQ) process; control the at least one transceiver to transmit second data based on the first HARQ process; based on transmitting the second data, generate third databased on the result of the first data being received; and control the at least one transceiver to transmit the third data based on a second HARQ process.

Abstract: 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.
