Abstract: A technique including: detecting at a communication device a first cell meeting one or more cell signal conditions for secondary cell transmission for the communication device, which communication device is currently served by at least a primary cell of a cellular network; determining whether the first cell belongs to a set of potential secondary cells for the communication device including another cell that the communication device has currently reported to the cellular network as meeting one or more cell signal conditions for secondary cell transmission for the communication device; and deciding whether to report said first cell to said cellular network dependent on the result of said determining.

Abstract: Various communication systems may benefit from appropriate configuration of when a device is required to be active. For example, enhanced machine type communication radio resource management requirements regarding device activity can be aligned with machine type communication physical downlink control channel monitoring. A method can include determining a discontinuous reception usage state of a user equipment. The method can also include selecting a monitoring performance requirement from a plurality of monitoring performance requirements based on the determined discontinuous reception usage stage. The method can further include power saving in accordance with the selected monitoring performance requirement.

Abstract: There is provided a method comprising including determining, at a user device, the occurrence of a first event, the first event being an indication to, after a first time period, provide a measurement report to a serving access point of a network, determining, at the user device, whether a second event has occurred, the second event being an indication to, after a second time period, initiate user device controlled handover from the serving access point of the network, determining whether a handover command has been received from the network in response to the measurement report and prior to expiry of the second time period and, if not, determining to initiate user device controlled handover.

Abstract: The disclosure relates to communication in unlicensed radio spectrum based on a discontinuous reception pattern where preconfigured periods are provided for communication of control information. A determination is made that a station is not accessing a transmission channel during at least a part of a preconfigured period. The preconfigured period for signalling the control information is then extended in response to the determining that the station is not accessing the channel. The determining and extending can be provided in a base station and/or communication device communicating with the station.
