  • Patent number: 9930673
    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.

  • Publication number: 20180084449
    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.

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.
