Claim:
1. A method performed by a first device for sending a modified encoded radio block to a second device, the first device and the second device operating in a wireless communications network, the method comprising: selecting a set of bit positions of an encoded radio block, wherein the encoded radio block has the second device as intended recipient, wherein the set of bit positions is unique to a value of an extended Temporary Flow Identifier, eTFI, assigned to the second device, or wherein the set of bit positions is unique to a case in which no eTFI has been assigned to the second device, performing a modulo-2-addition of the selected set of bit positions of the encoded radio block with a pre-determined bit pattern, to obtain a modified encoded radio block, and sending the modified encoded radio block to the second device.
