METHOD FOR TRANSCEIVING INFORMATION OF TRAFFIC INDICATION MAP

摘要

The method includes generating a delivery traffic indication map (DTIM) beacon including a segmentation information element, and dividing the TIM information of the TIM transmission target page into the segments with variable sizes using the DTIM beacon and beacons within a DTIM interval corresponding to the DTIM beacon, and transmitting the divided segments. Accordingly, downlink traffic stored in a buffer of an AP can be appropriately distributed in a predetermined range, and therefore power consumption required for terminals operated in a PS mode to receive downlink frames stored in the buffer of the AP can be reduced. In addition, only a single beacon frame can be transmitted together with a single TIM segment, and therefore a size of the beacon frame can be appropriately adjusted.
