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： 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 (10 or 40) or system (200) of predictive sensing of periodic intermittent interference (PII) can include the measuring (12) of energy on a channel for an indication of PII, determining (14) if a channel is currently in a PII on-cycle, and adjusting (16) a clear channel assessment threshold to a new threshold for improved sensitivity of the PII on-cycle. If a current energy level on the channel is below the new threshold and if a previous on-energy characteristic suggests that the current energy level will remain below the new threshold for a predetermined minimum period of time, then a clear channel indication can be provided (20). A busy channel indication is provided (45) when either the current energy level is above the new threshold or the previous on-energy characteristic suggests the current energy level will not remain below the threshold for predetermined minimum period of time.

摘要： A method (10, 40, 50 or 55) or system (200) of detecting and avoiding periodic intermittent interference (PII) can include monitoring (12) for PII on a current channel which can include monitoring (14) by tracking retransmission statistics of isochronous traffic or by tracking channel probe request failures corresponding to temporal characteristics of microwave oven interference where PII is detected if the retransmission statistics exceed a predetermined threshold or if the probe failure requests exceed another predetermined threshold. The method can further include selecting (16) a channel or an adjacent channel with a highest level of PII when PII is detected on the current channel which can optionally include selecting (18) a preset channel known for PII interference or adaptively selecting by directly measuring energy levels on a plurality of channels. The method can switch (20) to a preferred channel when PII is no longer detected on the current channel.

摘要： A mobile terminal (302, 304) wakes up from a low power state and initiates a frame exchange in a wireless local area network that supports voice traffic by transmitting a polling frame (602). If the mobile terminal had voice data to send, it is included in the polling frame. In response to receiving the polling frame, the access point transmits a delay frame (604) to acknowledge receipt of the polling frame. If the access point has data for the polling mobile terminal, it transmits a non-delay frame (606) including the voice data, otherwise it transmits a null frame (702). The mobile terminal acknowledges the data from the access point (608), and goes back to sleep until the beginning of the next service interval.

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 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.

摘要： A method for accessing a wireless local area network (WLAN) channel and providing quality of service (QoS) for voice in a system supporting both voice and data services. Under the method, a communication device (302, 303) contends for a medium (channel). Upon identifying a transmit opportunity, the device transmits a voice packet to an access point (AP) (304) and polls the AP for downlink traffic. A low power implementation is feasible because the communication device can sleep, wake up to contend for the medium, transmit a voice packet to the AP, request a voice packet from the AP, transmit an acknowledgement, and go back to sleep.

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： 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.
