Abstract: The inventive concept relates to a distributed antenna system (DAS), and more particularly, to an uplink signal transmission operation of each of node units constituting a DAS. A node unit of a DAS includes a multiplexer configured to generate a single uplink signal by selectively outputting any one of m uplink signals received from m lower node units at an interval of a predetermined output time, where m is a positive integer greater than 1, and a down-sampler configured to output a transmission uplink signal by converting a sampling rate of the single uplink signal to correspond to a sampling rate of any one of the m uplink signals. Accordingly, it is possible to provide a DAS capable of processing and outputting, as one signal, uplink signals received from a plurality of remote units, without any error.

Abstract: In a relay managing method through a network management system (NMS) server, a registration request is received from a relay BTS interface unit (BIU). The identification information of the BIU that transmits the registration request is compared with a previously registered BIU registration table, and a new BIU ID is provided to the BIU that transmits the registration request, when information corresponding to the identification information of the BIU that transmits the registration request does not exist in the BIU registration table. Subsequently, registration is performed by mapping the identification information of the BIU that transmits the registration request and allocation IP information to the provided new BIU ID.
