Abstract: From a plurality of messages provided by at least a first license-exempt access node which give usage information for the at least one channel in license-exempt radio spectrum, there is derived channel-specific statistical traffic information. This information for the channel is then provided to a second access node that controls licensed radio spectrum.

The second access node retrieves this information from its local memory and sends on the licensed radio spectrum a downlink message having contents, determined from the channel-specific statistical traffic information, for aiding a user equipment UE to access the channel with a probability defined by the contents. The UE receives this message, extracts the contents, and attempts to access that channel in the license-exempt radio spectrum utilizing the defined probability.

Abstract: A method and an apparatus for switching D2D data communications between a licensed and a license-exempt band are disclosed. A D2D device receives from a cellular network a pre-switch notification to prepare for a switch of its D2D communications, and in response adopts a temporary strategy for conducting its D2D transmissions prior to the switch. After the switch the D2D device discontinues the temporary strategy. In one embodiment the temporary strategy and its duration are indicated in the pre-switch notification. Two example temporary strategies are presented: ‘no-new-data’ where new data transmissions are suspended and data re-transmissions are sent with high reliability; and ‘no-feedback’ where new data is sent with high reliability and data re-transmissions are suspended. Different embodiments have the cellular network access node or D2D device contending for the radio resource in the license-exempt frequency band.
