Abstract: A network broadcast method using a MAC unicast and an MPR node allows a source node to transmit a data packet to at least one MPR node which is located within one-hop distance from the source node and allows the at least one MPR node to transmit the data packet to each next-ranked MPR nodes. At least one normal node, which is not an MPR node while being located within one-hop distance from the source node, receives the data packet of the source node, which is transferred from the source node to an MPR node or transferred between MPR nodes through overhearing. Although the source node and MPR nodes are in a hidden-node relationship, collision is prevented, thereby minimizing data packet loss to improve the transmission reliability, and enabling the data packet of the source node to be reliably broadcasted on a network.

Abstract: A power saving apparatus and a method in a wireless communication system are provided. An Access Point (AP) buffers transmission frames for sleep-mode stations in a sleep-mode buffer. Upon wakeup from a sleep mode, a station sends a first control information frame indicating wakeup to the access point. The access point sends a second control information frame including a requested transmission length in response to the first control information frame to the station. The station generates a third control information frame, aggregates the third control information frame and user data frames to a first protocol data unit, and sends it to the AP. Then the AP generates a fourth control information frame, aggregates the fourth control information frame and buffered frames to a second protocol data unit, and sends it to the station.

Abstract: An encoding apparatus and a decoding apparatus in a transform between a Modified Discrete Cosine Transform (MDCT)-based coder and a hetero coder are provided. The encoding apparatus may encode additional information to restore an input signal encoded according to the MDCT-based coding scheme, when switching occurs between the MDCT-based coder and the hetero coder. Accordingly, an unnecessary bitstream may be prevented from being generated, and minimum additional information may be encoded.
