摘要： A method includes receiving, by a (STA) from an access point (AP), a message using a first radio access technology (RAT), where the STA is configured to operate in the first RAT and a second RAT determining whether to transition the first RAT to the second RAT in accordance with the message. The method also includes, upon determining to transition from the first RAT to the second RAT, transmitting, by the STA to the AP, a disassociation request, and transmitting, by the STA to a communications controller, an association request.

摘要： A method for reducing authentication signaling in a wireless network includes identifying a plurality of access points in a network belonging to a group. An access request message is received from a first access point associated with a device being in range of the first access point. A determination is made whether the device has been authenticated within the group. A proxy accept message is sent to the to the first access point in response to the device being authenticated with the group without communicating with an authentication server for authentication of the device. A master access point may be used in performing the reduction of authentication signaling in the wireless network.

摘要： Embodiments are provided herein for determining a synchronizing master for device-to-device (D2D) communication in a cellular network environment. In an embodiment, a user equipment (UE) receives a discovery signal comprising a timing reference, and determines a transmitter of the discovery signal. In accordance with the determination of the transmitter of the discovery signal, the UE performs one of synchronizing to the timing reference in the discovery signal and transmitting a second discovery signal. The UE performs the synchronizing to the timing reference if the transmitter of the discovery is a cellular network. Alternatively, the UE transmits the second discovery signal upon determining that the transmitter of the discovery signal is a second UE that is out of coverage of a cellular network.

摘要： A method for operating an access point includes receiving information from a first station configured to operate in a non-traffic-indication-map (non-TIM) mode, and determining if downlink data intended for the first station is available at the access point. The method also includes transmitting at least one of the downlink data intended for the first station to the first station, a data indicator indicating that the downlink data intended for the first station is available at the access point, information indicating downlink data is available for the first station, and a time indicator indicating a specific time when the downlink data intended for the first station will be sent to the first station.

摘要： Mobile stations can query independent basic service set (BSS) parameters of a group of Access Points (APs) by setting a Pre-Association Message Exchange BSSID Independent (PAME-BI) bit during Wi-Fi discovery. The PAME-BI bit may be included in a Generic Advertisement Service (GAS) request to indicate that an Access Network Query Protocol (ANQP) request carried by the GAS request is querying both independent and dependent BSS parameters. In some embodiments, the PAME-BI bit is included as a field in the ANQP query, rather than the GAS request message.

摘要： A system and methods are provided to enable differentiated association of stations (STAs) in a WiFi system and provide differentiated quality of service (QoS) based association. The embodiments include categorizing STAs that share a channel of the WiFi network into different association priority classes, wherein the STAs with higher association priority classes wait for shorter times before starting association with an access point (AP) over the shared channel. The association priority classes are assigned by the AP or the WiFi network and signaled to the STAs. Alternatively, the association priority classes are assigned by the STAs and indicated to the AP or the WiFi network. The association priority class is determined for a STA according to traffic type, device type, subscriber type, or a random number generator.

摘要： In one embodiment, a method for setting a clear channel assessment (CCA) threshold includes receiving, by a station from a first access point, a first message including an information element and determining a CCA threshold in accordance with the information element. The method also includes detecting a power level of a channel between the station and the access point to produce a first detected power level and comparing the first detected power level and the CCA threshold. Additionally, the method includes transmitting, by the station to the first access point on the channel, a second message when the detected power level is less than the CCA threshold.
