  • Patent number: 9832736
    Abstract: A method for gain control of an active DAS relay unit is disclosed, including: acquiring a downlink output power value of a remote unit accessing the active DAS, and acquiring an uplink maximum gain value of a relay unit of the active DAS; obtaining an attenuation adjustment value required to be set for an uplink where the remote unit is, based on a combination of the downlink output power value and the uplink maximum gain value; and setting an adjustable attenuator arranged in the uplink based on the attenuation adjustment value. A device for gain control of an active DAS relay unit and a relay unit are also disclosed. The present disclosure may be compatible with remote units with different power levels, simplify the complexity of the design of the coverage scheme, increase the flexibility of the network construction, and reduce the cost of the network construction.
