METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING SIGNAL IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18267320 titled 'METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING SIGNAL IN WIRELESS COMMUNICATION SYSTEM
Simplified Explanation
The abstract describes a method and device for transmitting and receiving signals in a wireless communication system. The method involves transmitting information of demodulation reference signal (DMRS) sequences and data transformation techniques to a terminal, transforming a data symbol sequence based on these techniques, performing an inverse discrete Fourier transformation (IDFT) on combinations of the transformed data symbol sequences and DMRS sequences, measuring peak-to-average power ratio (PAPR) values for each IDFT-performed signal, selecting the signal with the lowest PAPR value for transmission to the terminal.

Original Abstract Submitted
Disclosed are a method and device for transmitting and receiving a signal in a wireless communication system. The method may comprise the following steps: transmitting, to a terminal, information of a plurality of demodulation reference signal (DMRS) sequences and information of a plurality of data transformation techniques, transforming a data symbol sequence on the basis of the plurality of data transformation techniques, performing an inverse discrete Fourier transformation (IDFT) on combinations of the plurality of transformed data symbol sequences and the plurality of DMRS sequences, measuring peak-to-average power ratio (PAPR) values with respect to each of the IDFT-performed signals, selecting an IDFT-performed signal having the lowest PAPR value as a result of the measurement, and the selected IDFT-performed signal may be transmitted to a terminal.
