ABSTRACT:
Provided is a connection identification (CID) allocating method in a Broadband Wireless Access (BWA) communication system having a medium access control protocol data unit (MAC PDU) format with a header field including control information and a payload field including user data. The header field has a first CID field of a first length indicating a CID of a mobile subscriber station (MSS), a second CID field of a second length and indicating the CID of the MSS by being concatenated with a CID of the first CID field, and a type field indicating whether the second CID field is used. The method includes determining a CID to be allocated to a particular MSS; and if the length of the determined CID is equal to the first length, including the determined CID in the first CID field, including, in the type field, information indicating that the second CID field is not used, and transmitting the MAC PDU to the MSS.
