  • 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.

  • Methods and Arrangements for Managing a Retransmission by a Device on a Random Access Channel in a Wireless Communication Network
    Publication number: 20180302190
    Abstract: Methods and arrangements for managing a retransmission on a Random Access CHannel, “RACH”, in a wireless communication network (100). A device (600; 120) performs (404; 502) the retransmission on the RACH, wherein the retransmission is based on a coverage class associated with the device (600; 120). Basing the retransmission on the coverage class e.g. enables reduction of retransmission collisions when the wireless communication network (100) operates as in Extended Coverage GSM, “EC-GSM”.
