Abstract: A communication method for a third device that controls a first link established directly between a first device and a second device is provided. The third device allocates a first link identifier for identifying the first link. The third device transmits first information including the first link identifier to the first device and the second device. The third device receives, from the first device and the second device, second information including allocation acceptance information indicating the acceptance or rejection of allocation of the first link identifier.

Abstract: A cross carrier scheduling method is provided by a terminal. The terminal receives a control element including cross carrier scheduling configuration information from a base station, and sets a scheduling cell of a secondary cell in accordance with the cross carrier scheduling configuration information. The terminal starts to monitor scheduling information of the secondary cell at the scheduling cell from a time predefined between the base station and the terminal.

Abstract: A beamforming apparatus and method for expanding coverage of a control channel are provided, by which neighboring communication devices are classified according to the number of beams that they can receive, and therefore the frequency or period of beam transmission is adjusted to transmit a control channel by a beamforming method. Hence, an overhead reduction and an increase in transmission rate can be achieved, and coverage holes can be prevented.
