WIRELESS DEVICE AND METHOD FOR SELECTING UPLINK TRANSMISSION PARAMETERS BY THE NETWORK AND SIGNALLING EXPLICITLY WITH A CHOSEN PHYSICAL DOWNLINK CONTROL CHANNEL REGION

摘要

The present invention relates to a method for selecting a set of uplink transmission parameters. The method is performed in a wireless device of a radio communications system. The method comprises obtaining (410) information mapping resources of a physical downlink control channel region to at least two sets of uplink transmission parameters. The method also comprises receiving (420) a downlink control message on a resource of the physical downlink control channel region, and selecting (430) a set among the at least two sets of uplink transmission parameters. The selection of set is based on the resource of the physical downlink control channel region on which the downlink control message is received, and on the obtained information mapping resources of the physical downlink control channel region to the at least two sets of uplink transmission parameters.
