Multiple User Packet Repackaging

Revision A of the cdma2000 High Rate Packet Data (HRPD) Air Interface Specification includes a method to serve multiple users in a single packet (3GPP2, 2004), This method is know as medium access control (MAC) layer multiplexing and can facilitate up to 8 users in one packet. It allows Revision A of HRPD to be more effective, when compared to previous revisions of HRPD, in delivering real time applications such as voice, video, and gaming due to the latency improvement. This paper examines the impact on system capacity that results from a proposed technique whereby MAC layer multiplexed transmissions can be terminated prematurely once a certain number of the target receivers have successfully decoded the transmission. It was found that system capacity could be improved by up to 5.8%.
