Abstract: In a wireless communications system, a first station periodically detects a channel when a second station enters a sleep mode, and transmits, to the second station, a packet commanding channel synchronization when the channel is determined to be available. The second station wakes up from the sleep mode upon receiving the packet and attempts to compete to occupy the channel.

Abstract: Provided are multicast services to a direct communication terminal not connected to a base station. Upon receiving a multicast packet from the base station, a forwarding terminal connected to the base station establishes a multicast connection with at least one direct communication terminal having a direct communication group identifier mapped to a multicast IP address of the multicast packet, and transmits the multicast packet to the at least one direct communication terminal.

Abstract: PURPOSE: A method and a device for managing multicast resources efficiently provide limited resources for a plurality of users. CONSTITUTION: A resource manager (710) allocates a multicast resource to a multicast group, and generates a MAP information element (MAP IE). The MAP IE includes information of the multicast resource and a transmission indication for indicating whether the multicast resource is fragmented. A transmitter (720) transmits the MAP IE to the multicast group. The MAP IE further includes an allocation period indicating a period in which the multicast resource is allocated, and an expiry date in which allocation of the multicast resource is maintained.

Abstract: PURPOSE: A synchronous channel transmitting method, a device thereof, a synchronous channel receiving method, and a device thereof are provided to minimize the inefficiency of resources and the degradation of a synchronous channel preamble receiving performance due to the insertion of a fixed transceiving transition time. CONSTITUTION: A synchronous channel transmitting device (700) includes a transmitter (710), a receiver (720), and a controller (730). The transmitter transmits a synchronous channel preamble part after transmitting a synchronous channel message part. The receiver receives a dedicated channel from different terminals after the transmitter transmits a synchronous channel. The controller inserts a transition time gap in the end of the synchronous channel preamble part for a transceiving transition time of a terminal of the synchronous channel transmitting device.

Abstract: PURPOSE: A communication method of a base station and a terminal is provided to configure an optimal temporary topology for a multi-mode terminal. CONSTITUTION: Each terminal(210,220,230) transmits state information to each base station(100)(S240,S250,S260). When one of the terminals is selected from the base station, the selected terminal receives a mode conversion request from the base station(S280). The terminal is operated as the base station. The terminal is operated as a relay station.
