Abstract
A node (100, 200) of a cellular network controls sending of first uplink grants to a communication device (10). The first uplink grants indicate first uplink radio resources allocated to the communication device (10) and are sent in response to receiving scheduling requests from the communication device (10). Further, the node (100, 200) controls sending of second uplink grants to the communication device (10). The second uplink grants indicate second uplink radio resources allocated to the communication device (10) and are sent according to a configured periodicity. Depending on a periodicity of opportunities for transmission of the scheduling requests by the communication device (10) and the configured periodicity of sending the second uplink grants, the node (100, 200) controls an alignment of the sending of the second uplink grants with respect to the opportunities for transmission of the scheduling requests.
