  • Patent number: 9935742
    Abstract: A user equipment (UE) implements improved communication methods which enable uplink (UL) transmissions consistent with an UL timeline. The UE may have a transmit duty cycle and may transmit acknowledge/negative acknowledge messages to a base station according to the transmit duty cycle. Additionally, the UE may be configured to determine signal-to-interference-plus noise ratio (SINR) between the UE and the base station and compare SINR to a threshold. The UE may transmit redundancy versions of data in consecutive sub-frames with a duty cycle of two transmissions per X+1 sub-frames if SINR is equal or above the threshold and redundancy versions using a duty cycle of one transmission per X sub-frames if SINR is below the threshold. Further, the UE may be configured to communicate a number of UL HARQ processes supported by the UE, receive first information in a first sub-frame, and send second information X sub-frames after the first sub-frame.

  • Patent number: 9929853
    Abstract: A single carrier cable modem can be initialized on multiple channels. By initializing a cable modern on more than one channel, the error rate performance of short data packets in cable modems in an impulsive noise environment is improved. The advantage of low symbol rate transmission for short packets in an impulse noise environment is achieved without sacrificing burst capacity at a cable modem and without the complexity of transmitting multiple symbol waveforms simultaneously at a cable modem.

  • Patent number: 9930145
    Abstract: Embodiments are provided for header compression with online network codes. A header formulation is used in accordance with the network codes to reduce the header overhead. An agent node between a source of packets and a user equipment (UE) adds to a header in the packets block labels corresponding to blocks of data in the packets. The agent node further adds, to a payload portion of the packets, start and end times for transmitting the blocks. The blocks of data are encoded using an online network coding scheme and the packets are sent to an access node serving the UE. The access node receives the packets, compresses the header by compressing bits of the block labels based on a pre-defined finite number of paths between the agent node and a plurality of access nodes components serving the UE, and sends the compressed header in the packets to the UE.

  • Patent number: 9894579
    Abstract: The present invention relates to an improved method for handover of a mobile node from E-UTRAN to UTRAN in a scenario where SMS is the only service of the mobile node. The improved handover method allows saving radio resources by establishing the signalling connection for SMS exchange in the target network, and avoiding the data connection in the target network, since it is not used. The MME takes the decision to establish or not the data connection in the target UTRAN, and accordingly instructs the SGSN and UE to set the corresponding PDP contexts for the data connection to a “preserved” state, so as to avoid the establishment of same. Embodiments further relate to improved SMS delivery for IDLE mode UEs that activate ISR so as to avoid the involvement of the MSC server. Instead, packet-switched domain nodes are to be involved only.

  • Patent number: 9883520
    Abstract: An approach for selecting sets of communications channels involves determining the performance of communications channels. A set of channels is selected based on the results of performance testing and specified criteria. The participant generates data that identifies the selected set of channels and provides that data to other participants of the communications network. The participants communicate over the set of channels, such as by using a frequency hopping protocol. When a specified time expires or monitoring of the performance of the channel set identifies poor performance of the set of channels, the participant selects another set of channels for use in communications based on additional performance testing. By selecting channels based on the initial performance testing and performance monitoring, the communications network adaptively avoids channels with poor performance.
