  • Patent number: 11363498
    Abstract: A mesh network flow control method comprising: allocating a receiving window of a certain size between a parent node and each child node; the child node transmitting a window request to the parent node prior to transmitting a packet; upon receipt of the request, the parent node extracting the sequence number of the request of the child node; comparing the sequence number with a sequence number of the packet last received; calculating the size of an available window and replying to the child node with the size; and the child node transmitting the packet according to the size. Another method includes: a root node broadcasting information concerning a connection state between the root node and a server in a management frame of Wi-Fi, such that through information communication within a network, each node within the network can obtain the information, and then devices within the network transmit packets to the root node, thereby avoiding occupancy of bandwidth by unnecessary packet-transmissions.

  • Patent number: 11362959
    Abstract: Latency Based Forwarding (LBF) techniques are presented for the management of the latencies, or delays, of packets forwarded over nodes, such as routers, of a network. In addition to a network header indicating a destination node for receiving the packet, a packet also includes an LBF header indicating the packets accumulated delay since leaving the sender, a maximum latency for the entire journey from the sender to the receiver and a minimum latency for the entire journey from the sender to the receiver. When a packet is received at a node, based on the accumulated delay, the maximum latency, and the minimum latency, the node places the packet in a forwarding queue to manage the delays between the sender and the receiver. The LBF can also indicate a policy for the forwarding node to used when determining the enqueueing of the packet.

  • Patent number: 11272470
    Abstract: Provided are a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT), with a transmission and receipt processing method and device for time-frequency synchronization between V2X terminals. When a synchronization signal to be transmitted is identical to a synchronization signal of an existing D2D terminal, time-frequency resources configured for the D2D terminal in a cell are reused to transmit the synchronization signal. When synchronization signal to be transmitted is different from a synchronization signal of an existing D2D terminal, reconfigured time-frequency resources are used to transmit the synchronization signal. The synchronization signal transmitted by a V2X terminal indicates a corresponding synchronization source type by using a value of an SLSS sequence index and/or a value of a PSBCH specified field.

  • Patent number: 11265120
    Abstract: The invention provides a base station that does not cause the number of blind decodings to be increased and further can prevent the flexibility of resource allocation from degrading. A search space setting unit sets search spaces each of which is constituted by one or more control channel elements (CCEs) and each of which is to be decoded in the terminals and each of which is defined by a plurality of to-be-decoded candidates. An allocating unit places, in one of the plurality of to-be-decoded candidates included in the search space, a control channel. The number of connections of CCEs constituting the to-be-decoded candidate is associated with the number of to-be-decoded candidates. The search space setting unit causes, in accordance with the control channel to be transmitted, the association of the number of connections of CCEs constituting the to-be-decoded candidate with the number of to-be-decoded candidates to differ.
