Abstract: Disclosed is a method comprising providing a primary cell capable of serving a terminal device; determining a candidate secondary cell group, comprising one or more cells that have coverage area within the coverage are of the primary cell; determining, from the candidate secondary cell group, a cell that, based on information obtained before or during a connection setup signalling, has the highest probability of being successfully configured as a secondary cell for an inter-site carrier aggregation for the terminal device; and configuring the cell as the secondary cell for the inter-site carrier aggregation.

Abstract: A method comprising including controlling a receiver to attempt to receive a reference signal for cell discovery and/or cell signal measurement, wherein the reference signal is expected to be transmitted at a determined power level within a reference signal transmission window with instances of the reference signal transmission window separated by a first interval and the receiver is controlled to be able to receive the reference signal at a reference signal measurement time, with instances of the reference signal measurement time separated by a second interval; determining at the receiver at least one missing reference signal instance during the reference signal measurement time; and controlling the receiver to be able to receive at least one further reference signal instance at a further reference signal measurement time, the separation of the further reference signal measurement time and the reference signal measurement time being less than the second interval.

Abstract: A method includes determining an estimate of a data packet path time from a first base station 13 to a user equipment (UE), and determining, based at least partially upon a communication received from a second base station 15, an estimate of a data packet path time from the first base station 13 via the second base station 15 to the user equipment (UE) 10. The method includes, based at least partially upon the determined estimates, selecting either the first base station 13 or the second base station 15 to transmit a packet data unit (DPU) (PDU) to the user equipment (UE) 10.

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: There is provided a method for a mobile communication system comprising receiving at a communication device cell configuration information from a network node, and the configuration information being related to cells in a network area comprising a first cell and one or more second cells. Further, the method further comprises receiving at the communication device environment information indicative of overlaps between coverage areas of the first cell and the one or more second cells, and causing transmission of measurement results obtained in the first cell for use in radio resource management of the communication device in the one or more second cells.

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.
