Distributed Uplink Scheduling in CDMA Networks
Overview As mobile devices grow more powerful and diverse in the applications they run, it becomes increasingly desirable to give them some independence in scheduling their transmissions. The latest release of the CDMA2000 1xEV-DO system incorporates a number of mechanisms that afford mobile devices some flexibility in making uplink transmission decisions. With distributed decisions, however, comes the possibility of harmful interactions that could lower overall system efficiency. This paper carries out a preliminary investigation of a proposed token bucket based mechanism for enabling distributed transmission decisions. It explores a class of simple probabilistic policies that readily lend themselves to distributed operation, and show that their efficacy greatly depends on the number of devices sharing the uplink.
