Abstract: A network node (700), a wireless device and methods therein for handling radio resources when feedback signalling is employed to indicate either an acknowledgement, ACK, or a non-acknowledgement, NACK, of correct reception of data transmitted by the wireless device. The network node (700) assigns a shared radio resource to a group of wireless devices (702) to be used for retransmission in case the feedback signalling for a transmission of data indicates a NACK. When receiving a set of concurrent transmissions of data from the wireless devices (702) where a subset of the concurrent transmissions of data is not received correctly, the network node (700) transmits a NACK to those wireless devices that transmitted the subset that was not received correctly. The network node (700) then receives on the shared radio resource a retransmission of at least one of the concurrent transmissions of data in the subset that was not received correctly from at least one wireless device to which said NACK was transmitted.

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.
