Patent ID: 8842695

Claim:
A method for generating a multi user packet with transmission data and transmitting the multiuser packet from an access network transceiver system (ANTS) to a plurality of access terminals (ATs) in a mobile communication system including the ATs and the ANTS which are capable of performing packet data communication with ATs located in coverage thereof, the method comprising the steps of: generating a medium access control (MAC) header comprising n fields each for a different user packet of the multiuser packet, each field including an address of an AT receiving the user packet, a length of the user packet and a format for transmission data of the user packet; generating a MAC payload by consecutively connecting the n user packets such that each user packet of the n user packets is placed in the MAC payload; and generating a MAC trailer; wherein ‘0’ bits are padded to an end field of the MAC header if a predetermined size of the multiuser packet is greater than a sum of lengths of the MAC header, the MAC payload and the MAC trailer.
