Multi-Level Indicator Of Radio Resource Status For Intended D2D Transmission

Abstract:

A radio device receives a first message from a further radio device. The first message indicates an intention of the further radio device to perform a device-to-device radio transmission on a set of radio resources. The radio device determines a status of the set of radio resources. In response to the first message, the radio device sends a second message comprising an indicator which indicates the determined status of the set of radio resources in terms of at least three levels.
