Abstract:
A User Equipment (UE) D2D device transmits a coverage transition indicator when the UE device leaves a service area of base station and is no longer in coverage. The coverage transition indicator at least indicates that the UE device has left the service area and is no longer in coverage. Based on the coverage transition indicator, a determination can be made as to whether the D2D group to which the UE device belongs has transitioned to an out of coverage scenario from a partial coverage scenario.
