| Abstract(in English) | Packet Division Multiple Access (PDMA) is a new paradigm for cellular internetworking. As the Internet is becoming the only information infrastructure, data units can be identified by IP header only that duplex and multiplex can be performed packet-wise only. Moreover, with the current best-effort Internet, traffic varies very much and often and the traffic is asymmetric that (half-) fixed bandwidth allocation with conventional CDD/FDD/TDD/CDM/FDM/TDM wastes a lot of bandwidth. PDMA is a paradigm to share the same communication channel by all the cells and allocate communication time slot fully dynamically packet by packet using CSMA/CA. With CSMA/CA, channel assignment design for each cell is unnecessary and multiple providers can share the same communication channel with automated negotiation. With preliminary analysis, PDMA is expected to be as efficient as (half-) fixed bandwidth allocation paradigm, save CSMA/CA overhead, even if traffic is persistent and stable. It is possible to introduce QoS assurance with, for example, prioritization. |
