1. A method of operating a network node that serves a cell in a cellular communication system, wherein an air interface of the cellular communication system is divided up into sequentially occurring frames, each of the frames comprising a plurality of sequentially occurring sub-frames, each of the sub-frames comprising a plurality of sequentially occurring symbols, the method comprising:

  • receiving and detecting a request signal transmitted by a device within the cell;

    based at least in part on a characteristic of the request signal that is indicative of one or more device capabilities of the device, ascertaining an associated time/frequency position for transmitting a response signal; and

    transmitting the response signal at the ascertained time/frequency position.
