  • Patent number: 9231880
    Abstract: A timer for processing data blocks is proposed for a receiver of a mobile communications system. If the timer is not running, the timer is started based a data block. The data block has a sequence number higher than a sequence number of another data block that was first expected to be received. If the timer is stopped or expires, the timer is based on a highest sequence number of a data block among data blocks that cannot be delivered to a higher entity. The timer can be used to prevent a stall condition in mobile communications.

  • Publication number: 20150373680
    Abstract: A method for a user equipment (UE) to generate a transmission is provided. In this method, a UE starts a time alignment timer when a time alignment command is received. The UE receives an uplink grant; and generates an initial transmission or a retransmission according to the uplink grant only when the time alignment timer is running upon receiving the uplink grant.

  • Patent number: 9210092
    Abstract: A method of moving a receiving window in a wireless mobile communication system, wherein the AM RLC of the transmitting side sends information of the last discarded SDU regardless of continuity of the discarded SDUs. The AM RLC of the receiving side checks whether all SDUs from the start point of the receiving window up to the last discarded SDU are successfully received, delivers the SDUs that are successfully received to an upper layer, and discard only those SDUs that are not successfully received.

  • Patent number: 9178662
    Abstract: A random access method for preventing unnecessary uplink (UL) signal transmission using a New Data Indicator (NDI) and a user equipment for the same are disclosed. In the random access procedure, in order to prevent unnecessary transmission when a user equipment erroneously recognizes a UL grant signal transmitted using a cell identifier (C-RNTI) of another user equipment as a UL grant signal transmitted using its temporary cell identifier (temporary C-RNTI), toggling of an NDI indicating whether new data is transmitted may be used in a Hybrid Automatic Repeat reQuest (HARQ) system. In addition, determination as to whether or not the UL grant signal received during the random access procedure is different from that of a HARQ process used for transmission of a third message (Msg3) may be used.
