An integrated transmission protocol for broadband mobile multimedia communication systems

This paper presents an integrated multimedia transmission protocol for future broadband mobile communication systems in the microwave band. The protocol is designed based on the physical layer devices using the CDM-(code division multiplexing) based parallel transmission scheme. Since the time-code-slicing technique is used, the proposed protocol is a joint CDMA (code division multiple access) and TDMA (time division multiple access). The protocol can allocate channel resources on demand of users with different information media and different QoS (quality of services) requirements and support wireless ATM system architecture. Since the protocol is based on the parallel transmissions, the SR-ARQ (selective repeat automatic repeat request) scheme is easily included in the protocol
