Abstract
The present invention relates to a method of measuring channel quality in a wireless access system and an apparatus for same. The method of measuring channel quality in a wireless access system includes the steps of: measuring channel quality using each CRS (cell-specific reference signal) transmitted in 0th, 4th, 7th and 11th OFDM (orthogonal frequency division multiplexing) symbols in each subframe from a base station; determining whether a channel quality measurement value of the 0th OFDM symbol is greater by a preset first threshold than an average value of channel quality measurement values of the 4th, 7th and 11th OFDM symbols; and transmitting channel quality information.
