- Description
- Control signal encoding results in coarse quantization impairments in today's cellular power control loops. The paper proposes a new approach for future cellular systems that enhances performance whilest retaining coarse quantization of the power control signal. The design applies novel optimal model predictive control (MPC) techniques in the base station, based on a model of an adaptive quantization zooming controller in the UE. This allows a high bandwidth with respect to set point changes and disturbances, at the same time as the quantization noise in stationary situations is minimized.
