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: This disclosure relates to the mobile communications field, and in particular, to data transmission technologies in the mobile communications field. In a data transmission method, a base station allocates, to a terminal, some of time domain symbols that are used for data transmission and that are in a scheduling period of the terminal, and the terminal performs data transmission based on the allocated time domain symbols. According to the method, time domain symbols in the scheduling period that originally belong to the terminal are punctured, a resource waste caused when the terminal occupies all time domain symbols that are used for data transmission and that are in the scheduling period during scheduling each time can be avoided, so that radio resources can be flexibly allocated based on requirements on delays and bandwidth, thereby improving resource utilization.
