Abstract: An apparatus for band-limited frequency division multiplexing for uplink transmission to a base station or access point, particularly from an IoT device, comprises a signal modulator to transmit a signal over a set of contiguous equally spaced frequency sub-carriers ranging from a lowest frequency sub-carrier via intermediate sub-carriers to a highest frequency sub-carrier. The signal modulator contains a filter to apply asymmetric filtering over the range of the frequency sub-carriers, thereby to reduce a peak-to-average power ratio of the transmitted signal.

Abstract: A device for assigning radio channels to radio transceiver devices. The device comprises an interface configured to receive two or more radio communication values, each associated with a radio transceiver device. The device comprises a processor configured to calculate an ordering of two or more radio transceiver devices based on radio communication values and build, according to the ordering, one or more rooted tree representing assignment of available radio channels to first radio transceiver devices according to the ordering. A branch of the rooted tree is selected according to a cost function value calculated along each branch. The processor is configured to assign the available radio channels to the radio transceiver devices according to the selected branch.
