ABSTRACT:
An embodiment of the present invention provides a method, comprising reducing overhead in OFDMA based Wireless Networks by determining the highest CIDs to be transmitted in a particular DL/UL MAP and determining the number of leading zero bits of the highest CID and removing the leading zero bits from each CID prior to transmission. Further, an embodiment of the present invention provides removing the CID field in the header of the message identified by a particular CID.
