  • Patent number: 11502795
    Abstract: A multi-user downlink orthogonal frequency-division multiple access (OFDMA) configuration method includes: assigning contiguous resource units (RUs) included in a channel to a plurality of stations, respectively; and assigning, by an access point (AP), one modulation and coding scheme (MCS) to each of the plurality of stations. Data rates of modulation and coding schemes that are assigned to first stations and associated with contiguous first RUs assigned to the first stations are monotonic, where the first stations are included in the plurality of stations.

  • Publication number: 20210345320
    Abstract: A method for acquiring and reporting resource needs of shared Access Points (APs) for multi-AP coordination is provided. A sharing AP transmits a control frame for Multi-AP coordination to a shared AP. The sharing AP receives a report on resource needs from the shared AP in response to the transmission of the control frame. The sharing AP allocates time-frequency resources of a Transmit Opportunity (TXOP) to the shared AP based on the report on resource needs.

  • Patent number: 8054745
    Abstract: A method for managing a call admission controller in a multi-hop wireless backhaul network is illustrated. The method provides a call access control mechanism in a multi-hop wireless backhaul network system by calculating at least one service quality parameter in the network and determining if service data transmitted from relay nodes is allowed to enter a gateway of the network according to the at least one service quality parameter. In exemplary embodiments of present invention, the service quality parameter includes a throughput, an average delay of packets, a number of remote devices, a packet loss rate, a number of the relay nodes, and an amount of service data of a specific class traffic in the network. A topology of the network may be a ring, a chain, or a tree topology, and a ripple protocol is utilized as media access control protocol in the network.
