摘要： 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.

摘要： The invention relates to a mechanism that allows the simultaneous transmissions in different parts of the available spectrum of an OFDM system, e.g. WiFi. An access point can thereby enable simultaneous transmissions from/to multiple client stations on different parts of the spectrum. This is achieved by implementing OFDMA that is transparent to the communicating stations by using multiple station identifiers, each of which is associated to a different part of the available bandwidth/spectrum in order to support simultaneous transmissions on the different parts of the bandwidth/spectrum.
