Efficient radio resource control for Manhattan street environments

We consider the combined control of mobile stations transmitter power and bit rate in CDMA microcellular environment. The objective is maximizing the number of QoS-satisfied mobile users in conjunction with minimizing network infrastructure cost. We first review the challenges associated with microcells and users mobility in a Manhattan-like street grid. Next, we discuss the additional aid offered by the combined scheme over the power-only method in utilizing the scarce radio resources efficiently. We demonstrate through link-level and system-level simulations the significant enhancements over the established power-only control scheme. Both coverage and spectrum efficiencies are improved for voice/data services having diverse QoS requirements.
