Abstract: An apparatus and method of searching a preamble signal in a search window for reducing a chip size of a preamble searcher in a transceiver of a base station is enclosed. By using a plurality of small window preamble searchers searching the preamble signal in a small search window, which is a division of a large search windows of a conventional preamble searcher divided by search start times, the preamble searcher of the entire search window can be implemented and the size of semiconductor chip is reduced by implementing distributing small preamble searcher in a small semiconductor chips.

Abstract: In a mobile IPTV system, a multicast coordination entity (MCE) acquires information for radio resource allocation for satisfying all terminals through a counting procedure, and determines a radio bearer by considering a share of usage anticipation subcarrier for respective identifiers of contents. A scheduling subject is variable by a characteristic of the determined radio bearer.
