Apparatus and method thereof for setting up device-to-device communication

摘要

The invention relates to a scheduling apparatus 109 for a cellular radio communication system 110. The apparatus comprises a processor. The processor is configured for obtaining an indication that direct (D2D) wireless communication should be set up between a first wireless communication terminal and a second wireless communication terminal of the communication system. The processor is also configured for measuring at least one metric of the communication system. The processor is also configured for allocating, based on said measurement, a first set of frequency and/or time resources (f/t resources) for D2D transmissions from the first terminal to the second terminal. The first set of f/t resources defines a first amount of signalling. The processor is also configured for allocating, based on said measurement, a second set of f/t resources for D2D transmissions from the second terminal to the first terminal. The second set of f/t resources defines a second amount of signalling. The second amount of signalling is less than the first amount of signalling.
