US Patent 10171136 Reducing internal signaling burden in the distributed antenna system

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 first information unit from the network by a first distributed unit (DU) among multiple DUs distributed within the UE. The first DU reports reception information of the first information unit to a central unit (CU) of the UE, wherein the CU controls the multiple DUs. The first DU receives, from the CU, a direction regarding a transfer of the first information unit to the CU, and transfers the first information unit to the CU when the direction indicates a specific value.
