IMPROVED UPLINK SCHEDULING IN A CELLULAR SYSTEM

摘要

A method (600) for use in a cellular system (200), in which there are controlling nodes (210) which schedule (605) control messages from users (230) in a cell to the controlling node by transmitting uplink grants to the users. A controlling node: transmits (610) a downlink control message to a user, and estimates, based on the nature of the downlink control message, the size of an uplink control message in response from the user (230) and a transmit time when the user will be ready to transmit the control message, and transmits an uplink grant (620) to the user (230), designed to fit the estimated size of the control message from the user and the estimated transmit time.
