METHOD AND DEVICE FOR DRAWING IE MAPS USING REDUCED CID IN BROADBAND OFDMA SYSTEMS Russian patent published in 2009 - IPC H04B7/26 

FIELD: physics; communications.

SUBSTANCE: present invention pertains to access systems with multiplexing with orthogonal frequency division of signals and particularly, to the method of separating data packets for a mobile subscriber station (MSS). This is provided for through transmission of information on separation of packets by the base station in the wireless broadband communication system, in which the transmitted frame consists of symbols, and orthogonal sub-carriers at the frequency axis combine each of the symbols based on the given time unit. The reduced connection identifier is generated through reduction of the basic CID of the mobile terminal, connected to the base station, if the main CID exists in the given range. A MAP, comprising enabled field, in form of reduced CID and either used, or unused reduced CID, is inserted into a frame, and the frame is transmitted to the mobile terminal.

EFFECT: provision for control of reduction of connection identifier (CID) of terminal, connected to base station through provision for system information, indicating whether CID in the wireless broadband communication system has been reduced to frame.
