ABSTRACT:
A novel implementation of a partitioned medium access control (MAC) is disclosed. The illustrative embodiment employs a shared bus that typically is already present in a wireless terminal for communication between an upper MAC and a lower MAC. The partitioned MAC implementation therefore does not require any additional communication means between the upper MAC and lower MAC, resulting in a lower-cost system. In addition, the upper MAC and lower MAC pass native data structures by reference over the shared bus, thereby eliminating the need for drivers to coordinate communication via interrupts, handshaking, etc. The partitioned MAC implementation results in a cost-effective distributed architecture in which the upper MAC resides in the terminal's host processor, and the lower MAC resides in the terminal's wireless station.
