Abstract: The present document is for a wireless communication with reduced internal signaling burden in the distributed antenna system (DAS). In the proposed method, a user equipment (UE) receives a decoding unit, from the network, by multiple distributed unit (DUs) distributed within the UE, and decodes the decoding unit, at each of the multiple DUs. Each of the multiple DUs reports first information on the decoding result to a central unit (CU) controlling the multiple DUs, and the CU determines decoded bit values of the decoding unit based on the first information acquired from each of the multiple DUs.

Abstract: A method and device for receiving a signal in a wireless communication system to which a multiplex transmission technique is applied are provided. The wireless communication system proposed herein suggests a method for increasing the receipt reliability of a terminal with respect to a multiplex transmission activation indicator indicating the start of multiplex transmission. Particularly, a terminal checks the receipt of a multiplex transmission activation indicator transmitted, from a first base station, for every predetermined subframe. If the terminal succeeds in receiving the multiplex transmission activation indicator, an ACK signal associated with the multiplex transmission activation indicator is transmitted to the first base station. Here, the multiplex transmission activation indicator indicates that the first base station and a second base station are capable of transmitting the same data for a predetermined time together.
