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 client type communication device for communicating with an access point type communication device is provided. The client type communication device comprises a communication unit adapted to use at least one of first communication resources for performing a random access communication if the client type communication device is in an associated mode regarding the access point type communication device, and to use at least one of second communication resources different from the first communication resources for performing a random access communication to the access point type communication device if the client type communication device is in a non-associated mode regarding the access point type communication device.
