- The WiBro (Wireless Broadband) system is designed to be able to provide a variety of information and multimedia contents services through high speed wireless Internet access via various user terminals such as PC, PDA and hand-held PC. The WiBro system can be considered as a system that integrates services in wired-realm and a wireless service. The WiBro system consists of three major entities; WiBro-AT(Access terminal), WiBro-AP(Access Point) and PAR(Packet Access Router). WiBro-AT provides interface with users of WiBro service, it is the most important factor for successful launching and fast expansion of commercial WiBro service. In this paper, we present an execution model of MAC on system kernel for uplink packet transmission of WiBro Access Terminal. It uses tasklet and kernel thread for a data processing an it also uses circular queue for delayed function call of queue operation. It gives stable running of WiBro-AT in spite of non-atomic execution property of tasklet.
