Described is a method of 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;. . . &#x3b8;i . . . &#x3b8;) and determining a maximum magnitude &#x3b8;value from said likelihood calculation. The method includes comparing said maximum magnitude &#x3b8;value to a selected, calculated or predetermined scaled threshold S&#xb7;&#x3c4; where &#x3c4; is a threshold and S is a scaling factor for the threshold &#x3c4;. The comparison step is such that, where |&#x3b8;|&#x3e;S&#xb7;&#x3c4;, the method comprises determining that the signal received comprises a linear block encoded signal. In the method, prior to said comparison step, the scaling factor S is selected from a plurality of scaling factor options. One scaling factor option (i) is a scaling factor Sderived from a combination of estimated noise and/or signal power at an output of a resource element (RE) demapper module and an estimated channel response from/before an equalizer module of said UCI receiver. The options also include using a combination of Sand a suitable scaling factor derived excluding option (i).
