METHOD AND APPARATUS FOR RELIEVING DOPPLER BROADENING IN WIRELESS ACCESS SYSTEM THAT SUPPORTS SUPER HIGH FREQUENCY BAND

摘要

The present invention provides methods for relieving effective Doppler broadening in performing pin-point beamforming and provides apparatuses for supporting the methods, wherein the methods and the apparatuses are used in a wireless access system that supports a super high frequency band. The method for relieving Doppler broadening in a wireless access system that supports a super high frequency band according to one embodiment of the present invention may comprise the steps of: receiving a downlink signal at a receiving end; estimating a Doppler spectrum for the downlink signal received at the receiving end; and calculating a carrier wave shift value based on the Doppler spectrum estimated at the receiving end.
