Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). Methods and apparatuses for grid mapping are described. A method for operating a base station comprises configuring grid mapping patterns for a plurality of terminals, transmitting, to the plurality of terminals, the grid mapping patterns, receiving, from the plurality of terminals, information on which a grid mapping is performed based on the grid mapping patterns, and identifying data of the information corresponding to each of the plurality of terminals based on the grid mapping patterns. Therefore, the terminal can hold a low peak-to-average power ratio, and the power consumption can be effectively saved. The base station can complete signal detection in a moderate detection complexity by multi-terminal joint detection. The detection complexity and the performance are balanced.

Abstract: A filtering-based signal transmission method is provided. The method includes a transmitter performing carrier modulation on each signal from at least one sub-band, and adding a cyclic prefix and a cyclic postfix thereto, respectively, performing time-domain filtering on the signal, added with the cyclic prefix and the cyclic postfix, from the respective sub-band, and transmitting the filtered signal from the at least one sub-band. The present disclosure further provides a filtering-based signal receiving method. The filtering-based signal receiving method includes performing, by a receiver, time-domain matched filtering, corresponding to at least one sub-band, on each received signal, removing, by the receiver, a cyclic prefix and a cyclic postfix from the filtered signal from the at least one sub-band, and performing carrier demodulation, respectively, and detecting and estimating, by the receiver, the demodulated signal from the at least one sub-band.
