The transceiver (400) is in a first decoding mode. The transceiver (400) stores a received signal comprising a data block. The transceiver (400) decodes the received signal using the first decoding mode, thereby obtaining the data block. When an event is triggered, the transceiver (400) retrieves the stored signal. The transceiver (400) decodes the retrieved signal using a second decoding mode, thereby obtaining the data block. The transceiver (400) controls the interference cancelling in the transceiver (400), based on the data block decoded using the first decoding mode and the data block decoded using the second decoding mode. ## Claims ### Claim at position 1 1-12.
