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: 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.
