    Abstract: 적응형 방식은 무선 노드들에 의한 간섭 관리 메시지들의 송신을 제어한다. 예를 들어, 적응형 방식은 자원 사용 메시지들을 송신할지 여부 및/또는 송신하는 방법을 결정하기 위해 사용될 수 있다. 그러한 결정은 예를 들어, 서비스 품질 임계값과 수신되는 데이터와 연관된 현재의 서비스 품질 레벨의 비교에 기초할 수 있다. 서비스 품질 임계값은 이전에 송신된 자원 사용 메시지들의 효과에 기초하여 조정될 수 있다. 주어진 무선 노드에 대한 서비스 품질 임계값은 무선 노드가 자원 사용 메시지들을 송신하는 빈도에 기초하여 조정될 수 있다. 주어진 무선 노드에 대한 서비스 품질 임계값은 다른 무선 노드로부터 수신되는 정보에 기초하여 조정될 수 있다. 조정 방식은 또한 주어진 무선 노드에 의해 수신되는 트래픽의 타입에 좌우될 수 있다. 서비스 품질 임계값은 또한 처리량 정보에 기초하여 조정될 수 있다.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for controlling a traffic stream between mesh points in a mesh network. SOLUTION: Data arriving from the mesh point are aggregated in packet queues (814). The packet queues segregate arriving data by the Quality of Service (QoS) requirement of the data. An appropriate communication channel is selected. The communication channel is accessed through a contention access schema (808). An M-Request-To-Send (MRTS) message is sent to a potential receiving mesh point, and a receiving mesh point responds with an M-Clear-to-Send (MCTS) message (812). Data from the packet queues are transmitted to the next mesh point (814). A mesh point power save mode makes a battery-operated mesh point sleep, thus preserving power. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a method for selecting a channel at a mesh point in a mesh network. SOLUTION: Data arriving from the mesh point are aggregated in packet queues (806). The packet queues segregate arriving data by the Quality of Service (QoS) requirement of the data. A channel is selected from among a plurality of channels on the basis of the signal strength of a reception signal. An M-Request-To-Send (MRTS) message is sent to a potential receiving mesh points and a receiving mesh point responds to an M-Clear-to-Send (MCTS) message (812). Data from the packet queues are transmitted to the next mesh point (814). A mesh point power save mode makes a battery-operated mesh point sleep, thus preserving power. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a technology for rate selection in a MIMO system. SOLUTION: An access point transmits an unsteered MIMO pilot via a downlink. A user terminal estimates downlink channel quality based on a downlink unsteered MIMO pilot and transmits an unsteered MIMO pilot and feedback information via the uplink. The feedback information is indicative of the downlink channel quality. The access point estimates the uplink channel quality, obtains a channel response matrix based on the uplink unsteered MIMO pilot, decomposes the channel response matrix to obtain eigenvectors and channel gains for eigenmodes of the downlink, and selects rates for the eigenmodes based on the estimated uplink channel quality, the channel gains for the eigenmodes, and the feedback information.

    Abstract: Techniques for controlling transmissions in wireless communication networks are described. In one aspect, transmission control for a mesh network may be achieved by ranking mesh points or stations in the mesh network. In one design, the rank of a first station in the mesh network may be determined. At least one station of lower rank than the first station in the mesh network may be identified. At least one transmission parameter for the at least one station of lower rank may be set by the first station. In another aspect, stations may be assigned different transmission parameter values to achieve the data requirements of each station. At least one transmission parameter value may be selected for each station based on the rank, QoS requirements, amount of traffic, and/or achievable data rate for that station and may be sent (e.g., via a probe response message) to the station.
