  • Patent number: 11424861
    Abstract: A method and apparatus decode packetized data in the presence of packet erasures using a finite sliding window technique. A decoder receives packets containing uncoded and coded symbols. When a packet with a coded symbol is received, the decoder determines whether a packet sequence number is within a sliding window of w consecutive sequence numbers that are no greater than a decoder sequence number, where the number w is fixed prior to encoding. When this is the case, the decoder decodes the coded symbol into one or more of the w input symbols using the coefficient vector. Decoding may use a forward error correcting (FEC) window within the finite sliding window. Decoding also may use a technique of Gaussian elimination to produce a “shifted” row echelon coefficient matrix.

  • Patent number: 11425746
    Abstract: Generally, the described techniques provide for a user equipment (UE) generating a scheduling request (SR) for a set of data for an uplink transmission from the UE to a base station. The UE may determine whether the SR for the set of data is associated with a grant-free configuration for the UE. The grant-free configuration may indicate a set of time-frequency resources that the UE may use to transmit the set of data. The UE may transmit to the base station an indication of whether the SR is associated with the grant-free configuration. If the SR is associated with a grant-free configuration for the UE, the UE may use the corresponding resources to transmit the set of data to the base station, and the base station may then decode the data based on having received the indication of the resources by way of the grant-free configuration.

  • Patent number: 11284404
    Abstract: A device and method of avoiding future self-interference are described. During a current predetermined time period, a priori knowledge of an RF environment is used to determine a change in the environment in a next predetermined time period. Transmission on an interfering channel in response to the change leads to generation of an indication to another device to switch communications in the next predetermined time period to a new channel that is unaffected by transmission on the interfering channel. The new channel is set by the indication or is negotiated by the other device from a list of channels to use in the indication.
