Design and Analysis of Downlink Scheduling for Network Coverage for Wireless Systems

In this paper, we shall focus on the downlink scheduling design optimized for network coverage for wireless systems with multiple antennas. & proposed a wireless system consisting of a base station (with n(T) transmit antennas) and K client mobiles (each with single antenna). with multiple antennas, we have additional degrees of freedom for spatial multiplexing and spatial diversity, to include the spatial multiplexing into the framework, we first extends the conventional concept of network coverage to a more general utility-based network coverage to deal with the possibility of allocating resource to multiple users at the same time, consider the network centric utility and the user centric utility as two examples of the utility based coverage concept. raised on the generalized concept of network coverage, we proposed a systematic framework based on information the critical approach and formulate the scheduling design as a mixed convex and combinational optimization problem.
