Abstract: Described is a method and device for processing a signal received at an uplink control information (UCI) receiver in a wireless communication system. The method comprises processing a signal received on an uplink (UL) at said UCI receiver to transform said received signal into a likelihood calculation of possible transmitted codewords (θ1 . . . θi . . . θN). The likelihood calculation of possible transmitted codewords (θ1 . . . θi . . . θN) may comprise a multi-dimensional discrete Fourier transform (DFT) (θ1 . . . θi . . . θN) of said received signal. The multi-dimensional may be formed as a Hadamard Transform. The method includes determining a maximum magnitude θmax value from said likelihood calculation of possible transmitted codewords (θ1 . . . θi . . . θN) and then comparing said θmax value to a selected, calculated or predetermined scaled threshold c.τ where τ is a threshold and c is a scaling factor for the threshold τ. The comparison is such that, where θmax>c.τ, it is determined that the signal received on the UL at said UCI receiver comprises a linear block encoded signal. In some cases, the scaling factor c may be omitted.

Abstract: Described is a method and apparatus for processing an uplink (UL) signal at a Physical Uplink Control Channel (PUCCH) in a wireless communication system to determine a discontinuous transmission (DTX) state. The method comprises receiving a UL channel signal at a PUCCH receiver apparatus and, after resource element (RE) demapping of said received UL channel signal in said PUCCH receiver apparatus, normalizing a signal power of at least one signal element or resource. The normalized power is compared to a selected, calculated or predetermined threshold and, based on said comparison, a determination is made on whether or not a DTX state has occurred.
