    摘要： Techniques are disclosed for an adaptive and causal random linear network coding (AC-RLNC) with forward error correction (FEC) for a communication channel with delayed feedback. An example methodology implementing the techniques includes transmitting one or more coded packets in a communication channel, determining a channel behavior of the channel, and adaptively adjusting a transmission of a subsequent coded packet in the first channel based on the determined channel behavior. The communication channel may be a point-to-point communication channel between a sender and a receiver. The channel behavior may be determined based on feedback acknowledgements provided by the receiver. The subsequent coded packet may be a random linear combination of one or more information packets.

    摘要： This disclosure relates to orthogonal frequency division multiple access (OFDMA) communication in wireless local area networks (WLANs). According to some embodiments, a downlink OFDMA frame may be transmitted. An uplink OFDMA frame including acknowledgements associated with the downlink OFDMA frame may be received. The uplink OFDMA frame may be processed, in some instances including determining which devices receiving the downlink OFDMA frame transmitted an acknowledgement associated with the downlink OFDMA frame in the uplink OFDMA frame.

    摘要： Aspects of the present disclose provide various methods and apparatuses for communicating, controlling, and configuring component carrier and bandwidth part (BWP). A scheduling entity receives a capability report from a user equipment (UE). The capability report indicates a capability of the UE to utilize at least one of carrier aggregation (CA) or one or more bandwidth parts. The scheduling entity transmits a command to the UE to reconfigure at least one of a CA configuration or a bandwidth part (BWP) configuration. The scheduling entity determines an anticipated response timing of an acknowledgment (ACK) of the command based on the capability report received from the UE. The scheduling entity receives the ACK according to the anticipated response timing.

    摘要： A communication apparatus connected to a network over which data is updated every predetermined cycle is provided. The communication apparatus includes first scheduling means for securing a first communication band necessary for updating every predetermined cycle, first data to be used for control of a manufacturing apparatus or a production facility, second scheduling means for securing a second communication hand necessary for delivering second data to a destination within a designated time period in a communication hand other than the first communication band of communication bands of the network, and third scheduling means for securing a third communication band for transmitting third data in a communication band set as neither of the first communication band and the second communication band of the communication bands of the network.

    摘要： Multicast error detection and recovery may be provided. A join request for a multicast stream may be sent from a first network node to a second network node. The join request may be sent over a first link of a plurality of links between the first network node and the second network node. A redirect message indicating that the second network node cannot accommodate the join request may be received by the first network node from the second network node. In response to receiving the redirect message, the join request for the multicast stream may not be sent on a second link of the plurality of links by the first network node to the second network node. And in response to receiving the redirect message, an alternate upstream network node may be determined by the first network node to send the join request for the multicast stream to.

    摘要： The present disclosure provides a method of determining a DTX cause at an access node, comprising: transmitting, to a User Equipment (UE), an Uplink (UL) grant and a Downlink (DL) assignment in a same DL subframe; detecting whether Discontinuous Transmission (DTX) of at least one of UL data to be transmitted in response to the UL grant received by the UE and Hybrid Automatic Repeat Request (HARQ) Acknowledgement (ACK)/Negative Acknowledgement (NACK) to be transmitted in response to DL data related to the DL assignment received by the UE occurs; and determining a cause of the DTX based on a result of the DTX detection. The present disclosure further provides an access node using the method and a computer program product.
