The disclosed subject matter includes techniques for delaying network frames. In some examples, a system for delaying network frames can include a processor and a computer-readable memory storage device for storing executable instructions that can be executed by the processor to cause the processor to identify a network frame to be transmitted to a host device at a client device. The processor can also delay transmission of the network frame to the host device based at least on the network information and a frame deadline.

In one embodiment, a device may transmit, via a network to an application, a series of sensor measurements captured by the device, each sensor measurement having an associated timestamp based on a clock of the device. The device may receive, from the application, an indication that at least a portion of the series of sensor measurement were not received by the application. The device may determine, for those sensor measurements not received by the application, timestamp differences between their timestamps and a current time of the clock of the apparatus, after receiving the indication. The device may resend the portion of the series of sensor measurements to the application and their timestamp differences.

The present disclosure provides systems and methods which increase the throughput of a TCP-based communication between a first network node and a second network node. First, the first network node sent a first plurality of TCP segments to the second network node. Second, when the second network node receives a second plurality of TCP segments, which is all or part of the first plurality of the TCP segments, the second network node responds by sending one or more TCP acknowledgements to the first network node with the last sequence number of a last segment among all TCP segment within the second plurality of TCP segments. The present disclosure are able to increase the throughput of a TCP connection while decreasing its reliability.

A data retransmission method, apparatus, and system can improve a success ratio of data packet retransmission. A data retransmission method includes: after a source node continuously transmits at least two data packets to a destination node according to a go-back-N automatic repeat request, monitoring and decoding, by a relay node, the at least two data packets; storing a copy of a successfully decoded data packet; monitoring a response message to each data packet, where the response message is returned by the destination node to the source node; and sending a copy of a data packet that corresponds to a reception negative acknowledgment message to the destination node, when the monitored response message is the reception negative acknowledgment message.

A HARQ process number determining method and a related apparatus are provided. The method includes: obtaining a first hybrid automatic repeat request HARQ process number corresponding to a first configured grant CG physical uplink shared channel PUSCH; determining, based on the first HARQ process number, a second HARQ process number corresponding to a second CG PUSCH; and transmitting data on a first PUSCH corresponding to the first HARQ process number and a second PUSCH corresponding to the second HARQ process number.

An apparatus comprising means for: determining at least one expected arrival sequence of one or more expected data units to be transmitted over at least one network system; determining if at least one of the one or more expected data units does not arrive for transmission over the at least one network system as expected; and if it is determined that at least one of the one or more expected data units does not arrive for transmission over the at least one network system as expected, increasing transmission reliability of one or more data units adjacent to at least one expected data unit that has not arrived for transmission over the at least one network system as expected.
