摘要： A method for transmitting packets in a wireless communication network includes taking into consideration an antenna mode prior to transmission. The method includes determining a transmit antenna mode for a transmission between the node and at least one other node; when the transmit antenna mode is omni-directional, broadcasting a transmission schedule for the transmission omni-directionally; and when the transmit antenna is beamforming directional, broadcasting a transmission schedule for the transmission directionally on one or more transmitter beams. The method optionally can also take into consideration an antenna mode of a receive antenna between the node.

摘要： A method for selection of the association access point for a station in an infrastructure mesh network based on received signal strength and one or more "association bias" weights received from neighboring access points. Each weight corresponds to a packet length category. In one embodiment, stations measure received signal strength for received signals and decode the association bias information field(s) and corresponding packet length category thresholds that are received in management frames such as beacons. Stations use this information to select an access point for association that will minimize the overall mesh resource utilization for the traffic (i.e. packet lengths) being transmitted. The method includes three elements: network assistance, access point actions, and station actions.
摘要翻译：一种用于基于从相邻接入点接收到的接收信号强度和一个或多个“关联偏差”权重来选择基础设施网状网络中的站的关联接入点的方法。每个权重对应于数据包长度类别。在一个实施例中，站测量接收信号的接收信号强度，并且解码在管理帧（例如信标）中接收到的关联偏差信息字段和对应的分组长度类别阈值。站使用该信息来选择用于关联的接入点，其将最小化正在发送的业务（即分组长度）的总的网状资源利用率。该方法包括三个要素：网络协助，接入点动作和站点动作。

摘要： A wireless local area network (WLAN) includes an access point (102) and a mobile station (106). The mobile station can operate in a low power mode by shutting down a WLAN subsystem (204) of the mobile station. While the mobile station is in a low power mode, the access point buffers data received at the access point destined for the mobile station (706). The mobile station wakes up to initiate a service period by transmitting a trigger frame to the access point, and identifies a traffic stream to be serviced in the presently initiated service period. The access point begins transmitting response frames to the mobile station, identifying the traffic stream requested by the mobile station, and in at least one response frame, the access point may indicate the buffer status of another traffic stream associated with the mobile station to allow the mobile station to make decisions regarding data retrieval and power save state.

摘要： A mobile station establishes a schedule by which data is exchanged with an access point. The schedule allows the mobile station to use a low power mode (608) at times outside of the scheduled service periods. However, the mobile station may occasionally need to retrieve additional data from the access point, or transmit additional data to the access point, and so initiates an unscheduled service period to do so (614).

摘要： An access point (11) for a wireless local area network (10) transmits a beacon message during a service interval period (21). This beacon message identifies, in a preferred embodiment, those subscriber units to whom the access point will shortly be transmitting data. Subscriber units that are not identified in the beacon message and that do not have data themselves to transmit to the access point can implement a power conservation mode of operation until the next beacon message. Subscriber units that have data, such as voice information, to transmit can utilize the beacon message contents to at least estimate a likely time by when the access point will have concluded making its transmissions to the subscriber units. That estimated time can then be used to facilitate scheduling a time at which a given subscriber unit will contend for an opportunity to transmit its data to the access point. In a preferred embodiment, this scheduled transmission time can potentially occur either during a contention window that follows the service interval period or during a dynamic contention window that follows the transmissions of the access point and concludes with the conclusion of the service interval period. Subscriber units can then use intervening periods of time to effect their power conservation schemes of choice.
摘要翻译：无线局域网（10）的接入点（11）在服务间隔期间（21）中发送信标消息。该信标消息在优选实施例中标识接入点将不久正在向其发送数据的那些用户单元。在信标消息中未被识别并且没有数据本身发送到接入点的用户单元可以实现功率节省模式，直到下一个信标消息。具有数据（例如语音信息）要发送的订户单元可以利用信标消息内容来至少估计可能的时间，当接入点将已经结束向用户单元发送信号时。然后可以使用该估计时间来方便调度给定用户单元将竞争机会将其数据发送到接入点的时间。在优选实施例中，该调度的传输时间可能潜在地在遵循服务间隔周期的竞争窗口期间或者在接入点的传输之后的动态争用窗口期间出现，并以服务间隔周期的结论得出结论。用户单位然后可以使用中间时间来实现其选择的节能方案。

摘要： A mobile station (106) establishes a real time communication link via an access point (102) for carrying voice or other time-sensitive data. A WLAN subsystem (204) of the mobile station is normally kept in a low power state. Upon initiating a communication link the mobile station signals to the access point that unscheduled power save delivery mode will be used (614), and the access point reserves resources to assure the necessary quality of service. The mobile station initiates a frame transaction by first powering up the WLAN subsystem (712), acquiring the WLAN channel (407), and transmitting a polling frame. Upon successful receipt of the polling frame the access point prepares to reply with an aggregate response. The aggregate response commences by transmitting all data in an aggregate buffer, including both reserved and unreserved data buffers. Upon successful receipt of the aggregate response, the mobile station places the WLAN subsystem back into a low power state.

摘要： A method and system for secure processing of authentication key material in an ad hoc wireless network enables secure distribution of the authentication key material between a mesh authenticator (110) and a mesh key distributor (115), which may be separated by multiple wireless links. The method includes deriving a pairwise transient key for key distribution (PTK-KD) using a mesh key holder security information element (MKHSIE). A mesh authenticator pairwise master key (PMK-MA) is then requested using a first mesh encrypted key information element (MEKIE) that includes data origin information. Using the pairwise transient key for key distribution (PTK-KD), a second mesh encrypted key information element (MEKIE) is then decrypted to obtain the mesh authenticator pairwise master key (PMK-MA).

摘要： In the present invention, the subscriber unit (200) obtains a set of access point identifiers and measurement opportunity information for each access point identifier. A first measurement is performed on a first access point identified from the set of access point identifiers. A current timer value is determined after completing the step of performing, and a second access point identified from the set of access point identifiers in which to perform a second measurement is selected. Selecting the second access point is based on at least the measurement opportunity information for the second access point in relation to the current timer value.

摘要： A method and apparatus for establishing security associations between nodes of an ad hoc wireless network includes two authentication steps: an initial first contact step (authentication, authorization, and accounting (AAA)-based authentication), and a "light-weight" step that reuses key material generated during first contact. A mesh authenticator within the network provides two roles. The first role is to implement an 802.1X port access entity (PAE), derive transient keys used for encryption with a supplicant mesh point via a four-way handshake and take care of back end communications with a key distributor. The second role is as a key distributor that implements a AAA-client and derives keys used to authenticate a mesh point during first contact or fast security association. The key distributor and the on-line authentication server can communicate to one another without these messages being transported over mesh links.
