  • Patent number: 9554414
    Abstract: A method, apparatus and computer program product are provided to allow the idle period to be defined in a more tailored manner, such as on a per station or per class of stations basis, as opposed to on a per access point basis. In the context of a method, an indication of an idle period is caused to be provided to a station. The method also causes an association with the station to be maintained for a period of time that is at least partially defined by the idle period. The period of time for which an association is maintained with the station is different than a period of time for which an association is maintained with another station in an absence of communication with the another station. A corresponding apparatus and computer program product are also provided.

  • Patent number: 9531523
    Abstract: A geographic region in which an access point AP lies is divided into sectors, each sector associated with a group; and a station is assigned to a group based on location information of the station relative to the sectors. The station can assign itself to a group autonomously, after determining the number of groups from signalling received from the AP. Or the AP can do the group assignments, such as by assessing distance between adjacent stations. The AP can utilize the station's location information to test whether a first link between the station and a first node of a first group is sufficient. If the test indicates that the first link is sufficient the AP can assign the station to the first group, else it will utilize the location information to test whether a second link between the station and a second node of a second group is sufficient.

  • Publication number: 20160316397
    Abstract: Various systems, methods, and non-transitory computer-readable mediums for providing a quality of service (QoS) level for communication between a wireless device and a wireless local area network (WLAN) are provided. A user classification may be determined for a user associated with a wireless device.

In a method for use in an access point, a broadcast message is caused to be provided to the station(s). The broadcast message includes an indication of a type of stations to access the RAW and one or more of a duration of the slot(s) in the RAW allocated to a first type of station, a duration of the RAW allocated to the first type of station, a duration of the slot(s) in the RAW allocated to a second type of station or a duration of the RAW allocated to the second type of station. The method also provides for access for one or more stations of the type that was indicated within the slots of the RAW.

  • Patent number: 9426788
    Abstract: A wireless device transmits a device-to-device discovery signal using the same transmission resource that is used for transmitting uplink retransmissions to a base station by a second wireless device. The device-to-device discovery signal is transmitted at a power that is determined in accordance with a control signal received by the wireless device from the base station. In an example, the wireless device transmits the device-to-device discovery signal on an uplink control channel established for use for sending uplink control signals to the base station.

  • Patent number: 9374190
    Abstract: A method, apparatus and computer program product are provided for enhancing data exchange between an access point (AP) and station (STA) in a wireless network when the exchange must be interrupted for the AP to perform other services while data remains buffered for later exchange. AP downlinks an indicator that more data remains for exchange together with a request for the STA to enter sleep mode for a duration scheduled by the AP. Sleep duration may be sent in the medium access control (MAC) header of a data frame, with the indicator of more data and the indicator of the sleep mode request being contained in the frame control (FC) segment of the MAC header. The STA may uplink an acknowledgement (ACK) of the sleep mode. Alternatively, the AP may downlink an ACK of the STA's indication of more data confirmation together with sleep mode indication and duration.

  • Patent number: 9131471
    Abstract: A fixed or Mode II device enables a Mode I device for license exempt operation by providing to it a list of available license exempt radio channels and a parameter indicating an interval at which contact verification signals CVSs are to be sent. The CVSs verify whether the list remains valid. The fixed/Mode II device then repeatedly sends contact verification signals spaced in time from one another according to the interval. In various embodiments the parameter may be an explicit indication, or it may be implicit. A plurality of enabled Mode I devices each gets a device-specific list, and in one embodiment the interval is the same for each of them and the explicit indication is broadcast while in another the parameter is provided to each of them via unicast messages and the interval may differ.

  • Publication number: 20150195777
    Abstract: A method, apparatus and computer program product provide improved detection of overlapping wireless networks. In this regard, the method, apparatus and computer program product may utilize a processor, such as a processor on a wireless access point, to determine one or more parameters for a scan of a wireless network to identify overlapping networks. Wireless stations may utilize the parameters to determine the content of a scan report generated from a scan of the wireless network. The wireless stations may further utilize the parameters to determine which values should be monitored and/or recorded during the scan of the network. The wireless stations may respond to the access point with results corresponding to the parameters requested by the access point, and the access point may use the results to determine channel access parameters for other devices on the network, such as the wireless stations.
