  • Publication number: 20180302200
    Abstract: A network node, a User Equipment, UE and methods therein, for handling a message transmitted over a radio link. The network node generates a first set of identity check bits for a first part of the message, based on the message and a first check identity, and further generates a second set of identity check bits valid for a second part of the message, based on the message, the first set of identity check bits and a second check identity. The message is then transmitted over the radio link with the first and second sets of identity check bits attached. The UE performs a first verification check using the second set of identity check bits and the second check identity, and performs a second verification check using the first set of identity check bits and the first check identity. The UE then handles the second message part based on the first verification check and the first message part based on the second verification check.
