Abstract
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 (θ. . . θi . . . θ) and determining a maximum magnitude θvalue from said likelihood calculation. The method includes comparing said maximum magnitude θvalue to a selected, calculated or predetermined scaled threshold S·τ where τ is a threshold and S is a scaling factor for the threshold τ. The comparison step is such that, where |θ|>S·τ, 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).
