Title:
METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING SIGNAL IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/251518
Kind Code:
A1
Abstract:
Disclosed are a method for operating a terminal and a base station and a device for supporting same in a wireless communication system. As an example of the present disclosure, a method for operating a first device in a wireless communication system comprises the steps of: mapping dummy signals of pre-defined values to a first subcarrier set; mapping data signals to a second subcarrier set that is different from the first subcarrier set; generating an orthogonal frequency division multiplexing (OFDM) symbol in a time domain by transforming frequency domain signals including the dummy signals and the data signals into time domain signals; generating an OFDM symbol including a zero UW by summing cancellation signals generated using at least a portion of the OFDM symbol; generating a UW-OFDM symbol by adding a UW to the OFDM symbol including the zero UW; and transmitting the UW-OFDM symbol to a second device.
