Abstract:
In an operating method of a user equipment that exchanges signals with network nodes of a cellular radio access network, a quantity that is indicative of a current operating temperature of the user equipment is measured; the user equipment determines whether a threshold value relating to the operating temperature has been exceeded; if the threshold value is exceeded, temperature information is transmitted to a network node of the cellular radio access network, to indicate that the threshold value has been exceeded; in response, the user equipment receives an instruction to use a second set of operating parameters requiring a smaller average power input for the connection to the cellular radio access network in comparison with the first set of operating parameters; and the user equipment, in response to receiving the instruction, reconfigures its connection to the cellular radio access network so as to use the second set of operating parameters.

A method of operating a mobile radio communication terminal, in which execution of at least one step of the method is controlled according to a device parameter which is assigned to the mobile radio communication terminal and which has exactly one of two possible device parameter values which indicate whether the mobile radio communication terminal is permanently stationary or not permanently stationary.
Abstract:
A base station in a cellular radio network and user equipment assigned to a cell are linked by an air interface for communication on a respective communication channel in a communication band. The same communication band is common to at least one of the cells and to the user equipment on the respective communication channel of a cell. A jamming transmitter is detected by decoding a cell, by way of successful reading of control information of the cell, detecting a wideband power parameter representative of the communication band, and detecting a channel power parameter representative for a part of the communication band that is a communication channel. A narrowband jamming transmitter is indicated in the case that decoding of the cell failed, the wideband power parameter is not above a first threshold, and the channel power parameter is above a second threshold.

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 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.
