A scheme to identify the uplink border between two neighbouring cells (10, 20) in an LTE-based heterogeneous network, especially one Macro cell (10) and another Small Cell (20). A trigger event is configured for a connected mode UE (1) such that the UE is triggered to send the measurement report about the neighbouring cell (20) when the condition “neighbour is offset better than Pcell on UL” is fulfilled. Such a measurement report can be used by the current serving eNB (11) to decide whether one or more neighbouring cells (20) should be activated or handed-over to, and/or whether certain information should be sent to one or more neighbouring eNBs (21) so that they can start monitoring the uplink connection quality of the UE. In particular it is possible to offload at least part of the UE's uplink traffic from the serving cell (10) to a neighbour cell (20).
A wireless communication method wherein a terminal is within wireless communication range of at least one serving cell with which the terminal has at least uplink communication, and at least one neighbour cell with which the terminal has no uplink communication, the cells controlled by one or more base stations and transmitting at least reference signals for reception by the terminal, the method comprising:
A wireless communication system comprising:
A base station for providing a serving cell of a terminal in a wireless communication system, the terminal arranged for at least uplink communication with the serving cell and to detect reference signals from the serving cell and from at least one neighbour cell in the system, wherein:
A terminal for use in a wireless communication system, the system comprising one or more base stations which control cells for wireless communication;
