    摘要: This application describes an enhanced passive scanning method for a wireless local area network, including the steps of transmitting at least one of a beacon signal or a gratuitous probe response in a WLAN channel by an access point. The gratuitous probe response is a supplemental beacon signal that is transmitted at intervals between the occurrence of regular beacon signals, but contains only essential information to allow mobile station manage roaming and timing.

    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 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 communication device (e.g., 106) having multiple transmission modes employs a method of transmitting user information (309, 310) and intermittent overhead data (307, 308). The communication device (106) selects from a first transmission technique and a second transmission technique. When the first transmission technique is selected and overhead data (307) is to be transmitted, the communication device (106) replaces a first predetermined amount of the user information (309) with the overhead data (307) to form a data unit. When the second transmission technique is selected and overhead data (308) is to be transmitted, the communication device (106) replaces a second predetermined amount of the user information (310) with the overhead data (308) to form the data unit, wherein the second predetermined amount is less than the first predetermined amount. The communication device (106) then transmits the data unit formed by either transmission technique, such that when using the second transmission technique, an increased number of bits (506) are available over time to represent the user information, while a substantially equal number of bits (508) are available over time to represent the overhead data as compared to the first transmission technique.

    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: In one embodiment, a method includes launching an application on a first device. The application allows the first device to trigger a service based on a program being played on a second device. The first device captures a visual code being displayed in association with the program being played on the second device. The visual code includes encoded information for program ID information associated with the program being played on the second device and timing information associated with the program being played on the second device. The method determines the program ID information and the timing information from the encoded information included in the visual code and then triggers the service for the application using the timing information and the program ID information.

    摘要: Disclosed are methods and apparatus for displaying multimedia feeds. The method comprises receiving a plurality of multimedia feeds and, for each of the plurality of multimedia feeds, acquiring a value of a metric and displaying, on a common display, the plurality of multimedia feeds. The metric is variable and its value for a particular multimedia feed and for a particular time is dependent upon either events occurring within that particular multimedia feed at or before that particular time or upon a rating (by one or more entities), at that particular time, of that particular multimedia feed. The multimedia feeds are displayed on the common display such that a first feed is displayed in a manner different from the manner of display of a second feed, the first feed having a first metric value, the second feed having a second metric value, and the first and second metric values being different.

    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.
