Abstract: Described is a method and device for detecting a DTX state at a UCI receiver in a wireless communication system. The method comprises receiving a linear block encoded signal on an uplink at said UCI receiver and processing the received signal after resource element (RE) demapping to generate a soft bit sequence {right arrow over (s)}. The method includes selecting a plurality of bits in said generated soft bit sequence {right arrow over (s)} as comparison bits and comparing said selected comparison bits to corresponding bits in a reconstructed soft bit sequence {right arrow over (r)}. The reconstructed soft bit sequence {right arrow over (r)} is generated from a plurality of bits selected as reconstruction bits in said generated soft bit sequence {right arrow over (s)}. A comparison or correlation metric is determined between the comparison bits and the corresponding bits in the reconstructed soft bit sequence {right arrow over (r)}, and a determination is made of the occurrence of a DTX state by evaluating the determined comparison or correlation metric.

Abstract: Described is a method and device for detecting a DTX state at a UCI receiver in a wireless communication system. The method comprises receiving a linear block encoded signal on an uplink at said UCI receiver and processing the received signal after resource element (RE) demapping to generate a soft bit sequence s. The method includes selecting a plurality of bits in said generated soft bit sequence s as comparison bits and comparing said selected comparison bits to corresponding bits in a reconstructed soft bit sequence r. The reconstructed soft bit sequence r is generated from a plurality of bits selected as reconstruction bits in said generated soft bit sequence s. A comparison or correlation metric is determined between the comparison bits and the corresponding bits in the reconstructed soft bit sequence r, and a determination is made of the occurrence of a DTX state by evaluating the determined comparison or correlation metric.
