In the proposed method, a user equipment (UE) receives signals, from the network, by multiple distributed unit (DUs) distributed within the UE, wherein the multiple DUs comprise one or more main DUs and one or more sub DUs; reports, by the sub DUs, first reception information of the signals to one of the main DUs; reports, by the one of the main DUs, second reception information of the signals to a central unit (CU) controlling the multiple DUs based on the first reception information of the signals; and determines, at the CU, which one or more DUs among the multiple DUs are to transfer the received signals to the CU based on the second reception information of the signals."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hierarchical distributed antenna system","description":"The present document is for a wireless communication with reduced internal signaling burden in the distributed antenna system (DAS).
