A method performed by a receiver comprising a decoder for utilizing apriori information, the method comprising: ∘ receiving first information (S 510); ∘ determining first apriori information associated with the first information based on previously received second information (S 520); ∘ providing the first apriori information as first probability information as a first input to the decoder (S 530); ∘ decoding, by the decoder, the first information by using the first apriori information and by using a modulation and coding scheme, MCS, corresponding to a transmission rate of the first information(S 540); ∘ receiving subsequent third information subsequent to the reception of the first information; ∘ detecting whether a MCS used for the third information and corresponding to a transmission rate of the third information is lower or higher than a MCS used for the first information; ∘ if the MCS used for the third information is lower than the MCS used for the first information, decoding the third information without determining second apriori information associated with the received third information and without using the second apriori information for decoding the third information; ∘ if the MCS used for the third information is higher than the MCS used for the first information: • determining the second apriori information associated with the third information based on the previously received first information; • providing the second apriori information as second probability information as a second input to the decoder; • decoding, by the decoder, the third information by using the second apriori information and by using the MCS used for the third information. ∘ receiving first information (S 510); ∘ determining first apriori information associated with the first information based on previously received second information (S 520); ∘ providing the first apriori information as first probability information as a first input to the decoder (S 530); ∘ decoding, by the decoder, the first information by using the first apriori information and by using a modulation and coding scheme, MCS, corresponding to a transmission rate of the first information(S 540); ∘ receiving subsequent third information subsequent to the reception of the first information; ∘ detecting whether a MCS used for the third information and corresponding to a transmission rate of the third information is lower or higher than a MCS used for the first information; ∘ if the MCS used for the third information is lower than the MCS used for the first information, decoding the third information without determining second apriori information associated with the received third information and without using the second apriori information for decoding the third information; ∘ if the MCS used for the third information is higher than the MCS used for the first information: • determining the second apriori information associated with the third information based on the previously received first information; • providing the second apriori information as second probability information as a second input to the decoder; • decoding, by the decoder, the third information by using the second apriori information and by using the MCS used for the third information. • determining the second apriori information associated with the third information based on the previously received first information; • providing the second apriori information as second probability information as a second input to the decoder; • decoding, by the decoder, the third information by using the second apriori information and by using the MCS used for the third information.
