Existing cellular networks assume that interference from neighboring cells is treated as noise and mobile devices are selected (scheduled) to communicate based on performance metrics for each device. When sliding-window coded modulation (SWCM) is used however, the performance metrics depend on those of interfering devices in neighboring cells, and hence scheduling has to be performed simultaneously over multiple cells.
Researchers from UC San Diego in collaboration with Samsung Electronics have developed an electronic device and method for performing scheduling that presents enhanced transmission efficiency over a wireless communication network. This streamlined approach to this simultaneous scheduling task that can be implemented in low complexity. This invention proposes scheduling techniques for wireless devices that use sliding-window coded modulation over wireless networks consisting of multiple cells.
A method for performing scheduling by a first base station over a wireless communication network, and an apparatus therefor are provided. The method includes receiving first channel status information (CSI) measured by a user equipment (UE) positioned in coverage of the first base station and second CSI, determining a first transmission rate for any one of the at least one UE positioned in the coverage of the first base station and a second transmission rate for any one of the at least one UE positioned in the coverage of the second base station, determining a third transmission rate for a first UE among the at least one UE positioned in the coverage of the first base station and a fourth transmission rate for a second UE among the at least one UE positioned in the coverage of the second base station, and performing scheduling.
UC San Diego is seeking opportunities to develop this patent-pending technology into commercial products through non-exclusive licensing.
