Abstract

A node (100) of a cellular network sends an uplink grant (803) to a communication device (10). The uplink grant indicates uplink radio resources allocated to the communication device (10) in reoccurring time intervals. In response to detecting a need for an uplink retransmission (814) by a further communication device (10′) on at least a part of the allocated uplink radio resources in a certain one of the time intervals, the node (100) sends control information (808) to the communication device (10). The control information (808) temporarily disables utilization of at least this part of the allocated uplink radio resources in at least this certain time interval by the communication device (10).
