Abstract: A method performed by a target node (111) in a communications network (100). The method is for handling reconfigurations of a User Equipment (UE) (120) during a conditional handover. The target node (111) has received a conditional handover request for the UE (120) from a source node (110) and has sent a handover request acknowledgement to the source node (110) based on a current configuration of the UE (120). The target node (111) performs (401) synchronization and random access with the UE (120) based on the UE configuration used for the handover request acknowledgement. The target node (111) obtains (403), after performing (401) the synchronization, information regarding an updated configuration of the UE (120). The updated configuration has taken place since the handover request acknowledgement was sent to the source node (110).

Abstract: The present disclosure relate to a method performed by a UE (102) for handling an invalid SI signature in a communication system. The UE obtains SI and an associated SI signature for a cell. The UE (102) determines if the obtained SI signature is valid or invalid. If the signature is valid, the UE (102) determines to use the cell. If the SI signature is invalid, the UE (102) determines if the UE (102) is configured to bar cells or not. If the SI signature is invalid and if the UE (102) is not configured to bar cells with invalid SI signature, the UE (102) determines to use the cell. If the SI signature is invalid and the UE (102) is configured to bar cells with invalid SI signature, the UE (102) determines to bar the cell and select another cell to use.

Abstract: After receiving a handover command (22) that commands a wireless device (16) to perform a make-before-break handover (24), the wireless device (16) continues to receive from a source link (20-0) downlink data packets for an unacknowledged mode bearer (21), until after the wireless device (16) establishes a connection with the target link (20-1) as part of the handover. After the wireless device (16) establishes the connection with the target link (20-1), the wireless device (16) receives from the target link (20-1) downlink data packets for the unacknowledged mode bearer (21). The wireless device (16) preserves a downlink data packet sequence number receiver status for the unacknowledged mode bearer (21), by using the same downlink data packet sequence number receiver status for the unacknowledged mode bearer (21) before and after the handover.
