Summary:A method and apparatus for estimating a noise and interference power in a wireless communication system are provided. Once a receiver receives an uplink signal from a terminal through an uplink channel to which semi-orthogonal sequences can be mapped, an estimator estimates an average power of signal components of the uplink signal and an average power of noise and interference components of the uplink signal by using correlation characteristics of the semi-orthogonal sequences, and a converter converts the average power of the signal components and the average power of the noise and interference components into a Carrier-to-Noise and Interference Ratio (CNIR). In this way, by simply and accurately estimating a CINR using semi-orthogonality of an uplink channel, stable and flexible system management becomes possible.
