Abstract: The invention allows detection and evaluation of device-to-device (D2) potential prior to the establishment of a cellular connection between communicating mobile devices. Cellular radio access network information of an originating mobile device is obtained from a received session establishment message of session initiation signaling of cellular data communication. The obtained cellular radio access network information of the originating mobile device is compared to acquired cellular radio access network information of a terminating mobile device. Based on the comparison, it is detected whether the proximity between the originating mobile device and the terminating mobile device suffices to allow local cellular device-to-device data communication between the originating mobile device and the terminating mobile device.

Abstract: Downlink control signaling from a network to a user equipment UE associates at least a first logical channel or radio bearer with a first component carrier in a licensed frequency band and associates at least a second logical channel or radio bearer with a second component carrier in an unlicensed frequency band. The UE uses the associations to select which uplink data is sent on the first and on the second component carriers by multiplexing the uplink data on the at least first and the at least second logical channels or radio bearers. By example the downlink control signaling may be a MAC control element in a RRC_Connection_Reconfiguration message which semi-statically defines a multiplexing allowance for each of the logical channels or radio bearers. An example MAC control element has an information tuple giving the association and multiplexing status per channel/bearer. Certain embodiments also adapt transmit power scaling for licensed/unlicensed band operation.

Abstract: The present invention proposes methods, devices and computer program products in relation to a communication module configured for communication in a carrier aggregation mode aggregating a primary and at least one secondary carrier. Scheduling information is carried in a control channel of one of the carriers, the scheduling information being associated to a respective one of said aggregated carriers and designating search spaces for payload in a payload channel of said respective aggregated carrier. Sensing is performed responsive to a sensing command added to the scheduling information associated to said at least one secondary carrier, which sensing command commands sensing to be performed on said at least one secondary carrier.

Abstract: A network support node collects information about unlicensed spectrum in use by a first access node; and provides at least some of the information to a user equipment via a second access node which utilizes licensed spectrum. In various exemplary embodiments: the information is collected via an interface between the first access node and the support node which does not pass through the second access node; the support node sends a query for the information when previously collected information is outdated; the support node sends to the first access node a preferred set of whitespace channels and/or virtual channelization; and the support node sends parameters for either/both access nodes to report on the unlicensed spectrum. Example parameters are: frequency/bandwidth range for the unlicensed spectrum in use by the first access node, and/or frequency range for a common control channel transmitted by the first access node in the unlicensed spectrum.
