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.
