  • Patent number: 9532268
    Abstract: Methods, systems, and devices are described for wireless communication at a user equipment (UE). In some examples, the UE may identify an initialization and refresh (IR) packet at the radio link control (RLC) layer based the size of the IR packet, where the IR packet comprises a larger ciphered PDU size than a compressed RoHC packet. Accordingly, once the UE identifies the received packet as an IR packet, the UE may attempt to decipher the IR packet using one or more HFN offset values. In one example, the UE may determine whether the IR packet is deciphered correctly based on cyclic redundancy check (CRC) value of the deciphered IR packet. As a result, the present disclosure allows the UE to re-synchronize with the transmitting device by at least one of incrementing or decrementing an HFN value at the receiving device.

  • Patent number: 9525642
    Abstract: Ordering partial network traffic. In an embodiment, data packets are received from a network tap and separated into two queues. For each queue, a push-sequence is maintained to represent a sequence number that must be pushed in order to maintain a consecutive order. When both push-sequences are equal to the sequence number of their first packets, if the acknowledgement number of the first packet on one queue is greater than the push-sequence for the other queue and less than or equal to the push-sequence of the one queue, data is pushed off the other queue. Otherwise, a queue having the earlier timestamp is identified as a first queue, the existence of a next acknowledgement number is determined for the second (other) queue, and data is pushed off the first queue according to the existence of the next acknowledgement number. Gap packets may be generated to force progress.

  • Patent number: 9526103
    Abstract: Logic may implement a slot assignment scheme that uses information provided in traffic indication map (TIM) information element (IE) and restricted access window (RAW) parameter set (PS) IE to determine a station-to-slot mapping function for communication of slot assignments to stations for RAWs. The TIM IE may comprise a bitmap indicating paged and unpaged stations. The RAW PS IE may comprise a duration and a slot duration. Logic may implement the station-to-slot function by determining the number of slots in a RAW and correlating slot assignments for stations based upon a position for the station in the TIM bitmap. The TIM bitmap may identify each station via a bit on a page in the bitmap based upon an assignment of the station to a position in the TIM bitmap. The station-to-slot mapping function may use an offset for fair access.

  • Patent number: 9521673
    Abstract: A method for resolving a Temporary Block Flow (TBF) in a wireless network including one or more mobile stations exchanging data with a base station system. The method comprises receiving a RLC/MAC block and retrieving a first TFI in the RLC/MAC header. The TFI is compared to an assigned TFI. The capability for the associated MS to resolve TBFs based on extended TFI addressing is determined. If the received first TFI matches assigned TFI and represents a comprehensive TFI for the associated MS, the payload of the RLC/MAC block is decoded. When the first TFI matches assigned TFI value and is identified as a code point to an eTFI, at least a predetermined field of the RLC data block is decoded and an extended TFI, eTFI, is retrieved. The eTFI is compared with an assigned eTFI. Following a match, the payload of the RLC data block is decoded.

  • Patent number: 9516657
    Abstract: Since common E-DCH resources may be assigned from a single Node B, uplink macro-diversity may not be possible between neighboring Node B's. In addition, a user equipment (UE) assigned a common E-DCH resource may not be allowed to perform cell reselection. Thus, maintaining the assignment of a common E-DCH resource to a given UE for more than a few hundred milliseconds may result in unacceptable inter-cell interference, for example, when the UE moves closer to a neighboring cell controlled by a non-serving Node B. To overcome inter-cell interference and allow a more extensive utilization of the Cell_FACH state, a method may be used to detect and/or control inter-cell interference.
