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 (&#x3b8;). The likelihood calculation of possible transmitted codewords (&#x3b8;) may comprise a multi-dimensional discrete Fourier transform (DFT) (&#x3b8;) of said received signal. The multi-dimensional may be formed as a Hadamard Transform. The method includes determining a maximum magnitude &#x3b8;value from said likelihood calculation of possible transmitted codewords (&#x3b8;) and then comparing said &#x3b8;value to a selected, calculated or predetermined scaled threshold c&#xb7;&#x3c4; where &#x3c4; is a threshold and c is a scaling factor for the threshold &#x3c4;. The comparison is such that, where &#x3b8;&#x3e;c&#xb7;&#x3c4;, 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.

Method and device for detecting discontinuous transmission (DTX) for small block encoded signals

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.
