Abstract:
1. A communication device, comprising: a communication circuit configured to communicate in a first communication mode; a receiver configured to receive a switching delay information message indicating a pre-defined time interval by which start of communication in a second communication mode for carrying user and control data using a second frequency range according to a frame structure, wherein the frame structure comprises a plurality of radio frames each having a plurality of sub-frames, each sub-frame including a plurality of symbols, should be delayed after a switch from the first communication mode to the second communication mode, wherein the pre-defined time interval is shorter than one sub-frame, the pre-defined time interval is stored in the communication device, the pre-defined time interval is a multiple of an Orthogonal Frequency-Division Multiplexing (OFDM) symbol duration and the pre-defined time interval is at least one symbol long, a detector circuit configured to detect whether the pre-defined time interval has elapsed since the start of the switching from the first communication mode to the second communication mode if the communication circuit has started switching from the first communication mode to the second communication mode, wherein the communication circuit is configured to communicate in the second communication mode when the pre-defined time interval has elapsed since the start of the switching from the first communication mode to the second communication mode.
