Title:
METHOD FOR ESTIMATING DIFFERENCE IN INTER-SYMBOL PHASE ROTATIONS IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/135672
Kind Code:
A1
Abstract:
Disclosed is a method for estimating the difference in inter-symbol phase rotations in a wireless communication system. The method, which is carried out by a terminal, comprises the steps of: receiving, from a base station, control data associated with the transmission of a signal utilized in estimating the difference in inter-symbol phase rotations; receiving from the base station, by means of a particular resource, a first signal utilized in estimating the phase rotations; estimating the difference in inter-symbol phase rotations by means of the received first signal; receiving from the base station, by means of a symbol following the transmission symbol of the first signal, a second signal utilized for estimating the phase rotations; estimating the difference in inter-symbol phase rotations by means of the received second signal; and decoding the received signal in consideration of the difference in phase rotations estimated by means of the second signal.
