Abstract: An operation method of a first AN for a hybrid beamforming-based cooperative transmission in a C-RAN includes obtaining a spatial channel covariance with terminals subject to a service; selecting a set of terminals to be serviced from among the terminals subject to the service; determining a radio frequency (RF) precoding matrix by which interference between the terminals to be serviced is minimized; transferring information on the determined RF precoding matrix to a centralized processor (CP); and generating an effective channel by configuring an RF precoder based on the determined RF precoding matrix.

Abstract: Provided is a communication system that transmits a control channel using a downlink. The communication system may transmit, to the terminal, transmission information of uplink allocation information that indicates whether uplink allocation information is transmitted using a downlink, and the terminal may determine whether the uplink allocation information is included in a downlink frame, based on the transmission information of uplink allocation information. The base station may transmit, to the terminal, information associated with a resource which has a possibility of being used for transmission of a physical downlink control channel (PDCCH), and the terminal may decode the PDCCH in the resource which has a possibility of being used for transmission of the PDCCH.

Abstract: A method for reducing power consumption of a terminal that communicates with a base station in a mobile communication system using a multi-carrier structure composed of a primary component carrier and at least one secondary component carrier comprises: receiving a discontinuous reception (DRX) parameter group for multi carriers from the base station; and setting the multi carriers to the same parameter value, by using the received parameter group. The method for reducing power consumption of the terminal further comprises: performing a downlink control channel receive operation on each carrier according to a DRX cycle. As the base station in the mobile communication system using the multi-carrier structure simplifies the DRX process for reducing power consumption of a terminal by reducing signaling load for the multi-carrier control of the terminal, it becomes possible to reduce power consumption of the terminal.
