A method for use in a IEEE 802.11 device, comprising: wirelessly connecting, by the device, to a gateway that is part of a wireless local area network (WLAN), the gateway configured to operate as an access point (AP) for the WLAN and bridge the WLAN to the Internet; receiving, by the device from the gateway, an announcement message including a network identifier (NI) of a subnetwork of the WLAN, the subnetwork including the gateway and a first node that is also configured to operate as an AP for the WLAN; transmitting, by the device to the gateway, a request message to join the subnetwork; receiving, by the device from the gateway, a response message including a confidential credential for connecting to the subnetwork; establishing a first connection to the first node based on the confidential credential and the NI and beginning to operate as an AP for the WLAN.

A radio communication system comprises a communication channel for the transmission of data packets from a primary station having a plurality of antennas to a secondary station having at least one antenna. The channel comprises a plurality of paths, and the primary station transmits a plurality of to packets substantially simultaneously. Each of the plurality of packets is transmitted via a different subset of the plurality of paths.

The secondary station receives the plurality of data packets, determines whether each packet is received correctly and signals this determination as an acknowledgement or a negative acknowledgement to the primary station for each of the plurality of packets.

Each of the nodes counts the number of other nodes located in a communication area of the node among nodes in a multi-hop network, and determines the number of times to retransmit a frame based on the counted number of the other nodes. Each of the nodes transmits a frame to a destination node, and repeats retransmission of the frame the determined number of times until receiving a response to the transmitted frame. Subsequently, each of the nodes changes a route to the destination node to another route when it does not receive the response after repeating the retransmissions the determined number of times.

Approaches are provided for efficient bandwidth allocation for real-time service traffic flows, providing for assured QoS and efficient spectrum utilization. A terminal of a wireless communications network receives data from one or more associated interface devices. A snooper captures a session request message from one of the interface devices for initiation of a setup process to establish a communications session over the communications network, and parses the session request message to obtain associated session parameters. Inroute bandwidth requirements for the communications session are determined based on the session parameters. A bandwidth reservation process is initiated to obtain bandwidth allocations to satisfy the inroute bandwidth requirements. The session request message is held until completion of the bandwidth reservation process, whereupon the session request message is transmitted to a session controller at a core node of the network, and the setup process to establish the communications session is completed.

Some embodiments of the invention provide a method for interconnecting hub router clusters in an SD-WAN. The method is performed for each hub router of a first cluster and located in a first of multiple regions connected by the SD-WAN. The method establishes a connection with a respective hub router of a second cluster and located in a second of the multiple regions. The method sends, to a route reflector for the first region connected to the first cluster, a first peer-connection notification identifying the hub router as a next-hop for reaching the respective hub router. For each other hub router of the first cluster, the method receives from the route reflector a second peer-connection notification identifying the other hub router as a next-hop for reaching the other hub router's respective second cluster hub router for use in reaching edge routers connected to each other hub router's respective hub router.

The present disclosure relates to a pre-5th-generation (5G) or 5G communication system for supporting higher data rates beyond 4th-generation (4G) communication systems such as a long term evolution (LTE) system. The disclosure includes a first evolved node B (eNB) in a communication system supporting dual connectivity. The first eNB includes a controller configured to detect that a path between a second eNB and a terminal is blocked, and a transmitter configured to transmit, to the terminal, a first data unit of a plurality of data units to be transmitted through the path between the second eNB and the terminal.

A system and method adds and manages entries on a list of entries of routing information to allow the top entry to be used for routing to a destination corresponding to the list. Costs of a wireless link may be a function of the success rate experienced on that wireless link.

A radio communication system comprises a communication channel for the transmission of data packets from a primary station having a plurality of antennas to a secondary station having at least one antenna. The channel comprises a plurality of paths, and the primary station transmits a plurality of packets substantially simultaneously. Each of the plurality of packets is transmitted via a different subset of the plurality of paths, for example by arranging for each packet to be transmitted via a different antenna or antenna beam. The secondary station receives the plurality of data packets, determines whether each packet is received correctly and signals this determination (typically as an acknowledgement or a negative acknowledgement to the primary station for each of the plurality of packets. The signalling may be by any convenient means, for example transmitting each acknowledgement or negative acknowledgement via a different subset of available uplink paths.

Disclosed are a communication path determination method and device, which solve the problems of low transmission efficiency and long transmission time delay which may be caused by the existing path which is configured for a small cell needing to access a network for directly communicating through a wireless channel between the small cell and a macro base station. The method comprises: when a wireless node needs to access a network, acquiring, by the wireless node, an optimal communication path from same to the network; and communicating, by the wireless node, with the network through the acquired optimal communication path, wherein the optimal communication path indicates the wireless node to access the network through at least one auxiliary node, and at least one of the at least one auxiliary nodes is a wired node which is directly connected to the network. Since the wireless node accesses the network and communicate with the network through at least one auxiliary node with the function of being capable of providing the data forwarding service for other nodes, the quality and performance of data transmission between the wireless node needing to access the network and the network are improved, and the transmission efficiency of the wireless node is improved.
