Abstract: Provided are a method and an apparatus for transmitting an uplink reference signal in a wireless communication system. A terminal receives from a base station, information on the maximum repetition number of the uplink reference signal, determines the repetition number of the uplink reference signal using the received information on the maximum repetition number of the uplink reference signal and signal quality obtained through downlink synchronization, and repeatedly transmits, to the base station, the uplink reference signal according to the determined repetition number of the uplink reference signal. The base station determines the uplink coverage of the terminal on the basis of the repeatedly received uplink reference signal.

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 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.
