A method (10) of noise power estimation for PUCCH format 1/1a/1b in LTE system is provided which comprises: determining (11) at least one unused orthogonal cover code, OCC for data symbols and reference symbols in the PUCCH, and estimating (12) noise power by employing the at least one unused OCC, for Signal-Noise Ratio, SNR, calculation and Discontinuous Transmission, DTX, detection. Also, an apparatus of noise power estimation for PUCCH format 1/1a/1b in LTE system is provided. The performance of the noise estimation may be greatly improved, and thus enhancing PUCCH detection accuracy, especially in case of a large number of users in the network. |
