Abstract:
Provided is a method of communicating encoded traffic indication map (TIM) information that can reduce power consumption by reducing an unnecessary decoding process. A method of receiving, by a terminal, a TIM that is encoded in a hierarchical structure including a page, a block, and a sub-block includes receiving an encoded TIM from an access point (AP), extracting a page index from the encoded TIM, and extracting block bitmap information indicating whether blocks included in a page designated by the page index include a bitmap. Therefore, an unnecessary decoding process with respect to each delivery traffic indication map (DTIM) beacon can be reduced, thereby reducing power consumption of a low-power terminal.

Claim (Index 5):
A method of transmitting a beacon frame by an access point (AP) in a wireless local area network, the method comprising:\n generating the beacon frame including a traffic indication map (TIM), a first bitmap and one or more second bitmap, wherein: the TIM is based on a hierarchical structure that a page includes a plurality of blocks and a block includes a plurality of sub-blocks, and the first bitmap indicates presence of buffered data for each of one or more blocks, a second bitmap indicates presence of buffered data for each of one or more sub-blocks, and a sub-block indicates whether there is data for each of one or more terminals; and transmitting the beacon frame, wherein the one or more blocks are decoded by a terminal when the first bitmap indicates that there is a buffered data at the AP for the terminal.
