METHOD, APPARATUS AND COMPUTER PROGRAM TO MAP A DOWNLINK RESOURCE TO A RELATED UPLINK TRANSMISSION

摘要

In an exemplary embodiment a method includes using a predetermined parameter to determine a rate of uplink radio resources to downlink radio resources; mapping an uplink radio resource to a unique one of the downlink radio resources dependent at least in part on the rate; and receiving on the mapped unique one of the downlink radio resources a reply to the uplink radio resource. Apparatus and computer programs are also described, for both a user equipment and a network node.
