Abstract: A method for transmitting system information by a base node to at least one wireless communication device camping on the base node, the base node supporting a dedicated resource region for communication devices, which is capable of being deployed at least in-band and out-of-band relative to a common frequency band. The method includes collecting a configuration parameter for said dedicated resource region according to a predetermined time period and to arrange said configuration parameter in system information blocks. If the dedicated resource region is deployed in-band and a wideband transmission session is active, adding to at least one of the system information blocks a valid subframe indication for submitting system information blocks instead of wideband transmission blocks, and transmitting said system information blocks according to said valid subframe indication. In case it is not deployed in-band, transmitting the system information blocks unchanged in a carrier frequency outside of the common frequency band.

Abstract: A method for operating a wireless communication device in association with a first base station comprises: determining further suitable base stations. In case at least one suitable second base station characteristically different from the first base station is found, checking if a cell identifier of the second base station is listed in a neighbor cell list received from the first base station, and checking signaling power of the second base station. The second base station is rated as a fake base station if measured signaling power is significantly higher than the signaling power of the first base station, and the cell identifier of the second base station is not listed in the neighbor cell list. If the rating of the second base station as a fake base station is above a predetermined threshold: deleting second base station from a list of suitable base stations.

Abstract: A method for operating a low-mobility wireless device in a cellular network, wherein the low-mobility wireless device operates with an active base node, and the low-mobility wireless device operates in a first mode, in which measurements of transmissions of base nodes are diminished. When the cellular network is enhanced by a new base node, the active base node transmits a first indication at least to the low-mobility wireless device. The low-mobility wireless device, in response to the reception of the first indication, switches to a second mode of operation, comprising execution of at least one measurement of transmissions of base nodes, and transmits at least one measurement report to the then-active base node. The active base node, upon reception of a measurement report, updates neighbour relation data relating to the base node identified by a base node reference with information obtained from the received measurement report.
