Closed control loop for uplink scheduling

摘要

An exemplary scheduling system and method implemented in a base station comprises a modeling unit, a prediction unit, and a scheduling unit incorporated into a control loop. The modeling unit determines a modeled air-interface parameter by modeling, e.g., a load or interference parameter, associated with the mobile terminals during a current transmission interval based on an earlier set of scheduling grants generated for the mobile terminals. The prediction unit determines a predicted error for a subsequent transmission interval based on the modeled parameter and a measured parameter reported by the mobile terminals during the current transmission interval. The scheduling unit generates a new set of scheduling grants for the mobile terminals for the subsequent transmission interval based on the predicted error.

1. A method, implemented by a scheduling system in a network node, of scheduling uplink transmissions from one or more mobile terminals to the network node, said method comprising:
determining a modeled air-interface parameter associated with said one or more mobile terminals during a current transmission interval based on an earlier set of scheduling grants generated for said one or more mobile terminals; determining a predicted error for a subsequent transmission interval based on the modeled air-interface parameter and a measured air-interface parameter reported by said one or more mobile terminals during the current transmission interval; and generating a new set of scheduling grants for said one or more mobile terminals for the subsequent transmission interval based on the predicted error.
