1. A communication device comprising:
a plurality of distributed units (DUs) each comprising an antenna; and
a central unit (CU) disposed apart from each of the plurality of distributed units and configured to be connected to each of the plurality of distributed units through a plurality of DU links,
wherein the central unit measures a channel quality of each of the plurality of DU links, controls power to be cut off to a distributed unit corresponding to a DU link when it is determined that the DU link is in an abnormal status during an operation time of a timer TDU_link associated with a DU link connection in the central unit, and controls power to be supplied to the distributed unit corresponding to the DU link when it is determined that the DU link has returned to a normal status, and
wherein the distributed unit performs a hardware reset when a CU link is in an abnormal status before a third timer TCU_link determined by the distributed unit is terminated, and
wherein the operation time of the third timer TCU_link is set to be shorter than the operation time of the timer TDU_link associated with the DU link connection.
