  • RADIO NETWORK NODE AND A WIRELESS DEVICE, AND METHODS THEREIN
    Publication number: 20180332484
    Abstract: A Radio Network Node (RNN) and a method therein for providing improved robustness of a radio link between the RNN and a wireless device. The RNN and the wireless device operate in a communications network. The RNN transmits, towards the wireless device, a transmission with a first transmission mode associated with a first level of coverage extension. When a first period of time has elapsed, the RNN transmits, towards the wireless device, the transmission using a second transmission mode associated with a second level of coverage extension. The second level of coverage extension is higher than the first level of coverage extension.

  • MANAGEMENT OF INTEGRITY PROTECTION OF A LOGICAL LINK CONTROL PACKET DATA UNIT
    Publication number: 20180332051
    Abstract: A first node (800; 120; 130) for managing integrity protection of a Logical Link Control, “LLC”, Packet Data Unit, “PDU”, is configured to communicate in a wireless communication network (100). The first node (800; 120; 130) provides (301; 701) an LLC PDU with an indicator that indicates that an integrity protection has been applied to at least part of the LLC PDU. The indicator may indicates that a Message Authentication Code, “MAC”, field is comprises in the LLC PDU, relating to said integrity protection. The first node (800; 120; 130) sends (302; 702) the LLC PDU with the indication to another, second node (1000; 130; 120) that then may identify, based on the indication, that the received LLC PDU applies integrity protection.
