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: 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.

Abstract: A method of transmitting and receiving a control channel in a wireless communication system is provided. A base station allocates a data channel to a radio resource, adds start position information of the data channel into a payload of a control channel, and performs signaling for indication information on the start position information added into the payload of the control channel to a terminal. Accordingly, the legacy system and the enhanced system can efficiently transmit a control channel.
