  • Patent number: 12035325
    Abstract: This application provides a feedback information sending method and apparatus and a feedback information receiving method and apparatus. A communications device to which the foregoing methods are applied sends or receives feedback information by using different feedback processes. When a network device does not determine whether a previous piece of feedback information is successfully received, the network device indicates a terminal device to send feedback information of a next piece of downlink data by using a new feedback process, and can schedule the next piece of downlink data without waiting for completion of processing of the previous piece of feedback information, thereby reducing a transmission delay.

  • Patent number: 11929925
    Abstract: A router encapsulates a payload of a packet in a generic routing encapsulation (GRE) header that defines a connectionless GRE tunnel. The router also encapsulates the payload and the GRE header in one or more reliable transport headers associated with a connection formed using a reliable transport layer. The router conveys the packet via the connectionless GRE tunnel over the reliable transport layer. In some cases, the GRE header is a network virtualization using GRE (NVGRE) header that allows multiple NVGRE overlays to be multiplexed onto a single IP underlay tunnel. The reliable transport layer can be implemented as Transmission Control Protocol (TCP) layer, a QUIC protocol, a Stream Control Transmission Protocol (SCTP) or a QUIC protocol to establish a set of multiplexed sub-connections or streams over a single connection between two endpoints of the tunnel, or a transport layer security (TLS) cryptographic protocol.
