Reverse traffic channel MAC design of cdma2000 1xEV-DO revision A system

cdma2000 1xEV-DO (DO), also known as IS-856, is a third generation (3G) wireless solution providing high-speed mobile Internet access. cdma2000 1xEV-DO revision A (DO-RevA) system provides further enhancements to DO, such as higher system capacity and advanced quality-of-service (QoS) support In this paper we motivate and describe the design of the reverse link traffic channel MAC (RTCMAC) of DO-RevA system, which uses a novel combination of centralized specification of flow behavior together with autonomous mobile packet allocation subject only to resource congestion control. We demonstrate that RTCMAC achieves full resource allocation flexibility through an efficient robust design, well suited to the CDMA reverse link.
