Title:
METHOD AND APPARATUS FOR SIGNAL PROCESSING IN A WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/256897
Kind Code:
A1
Abstract:
The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). The present disclosure provides a device in a wireless communication system and a method performed by the device. The method comprises: for a first transmitted signal transmitted by the device and a first received signal corresponding to the first transmitted signal and received by the device, compensating one of the first transmitted signal and the first received signal, according to a first synchronization delay part of a synchronization delay between a receiver and a transmitter of the device, wherein the first synchronization delay part is an integral multiple of a predefined baseband sampling interval of the device in the synchronization delay; determining a second synchronization delay part of the synchronization delay based on one of a collection of the first received signal and the compensated first transmitted signal and a collection of the first transmitted signal and the compensated first received signal, depending on which one of the first transmitted signal and the first received signal is compensated, wherein the second synchronization delay part is a fractional multiple of the predefined baseband sampling interval of the device in the synchronization delay.
