Abstract: Operating conditions of a remote device and operating conditions of a local device are compared, where the local device and the remote device are located within a predetermined proximity of a wireless network. An advertisement request is transmitted from the local device to the remote device based on the comparison of the operating conditions of the local device and the remote device. The advertisement request includes information identifying one or more services advertised by the local device, whereby the remote device is configured to advertise the one or more services on behalf of the local device in the wireless network.

Abstract: Methods and apparatuses for operating a wireless mobile station configured to communicate with a wireless access point are described. A wireless mobile station can determine an interval of time between successive target beacon transmission times. The wireless mobile station can adjust, based at least in part on the interval of time, a period of time of an awake timer in response to having determined the interval of time.

Abstract: Methods and systems for performing a round trip time determination between two devices are described. An example method may include publishing, over a wireless network interface by a first device within a neighbor aware network (NAN) cluster, a schedule that invites devices within the NAN cluster to request, within a time window, to perform a round trip time (RTT) determination with the first device. The schedule may indicate that the time window begins at a time offset from a NAN discovery window and ends after a predetermined period of time has elapsed. The method may also include receiving a request, from a second device within the NAN cluster, to perform the RTT determination with the first device. The method may also include performing the RTT determination with the second device.

Abstract: A local device is configured to monitor operating conditions coupled to a wireless network. An advertisement period is dynamically adjusted based on the operating conditions of the local device, where the advertisement period is dynamically adjusted based on at least one of a battery condition of the local device, a user behavior of the local device, network traffic condition, and a type of service to be advertised. The local device broadcasts a service advertisement in the wireless network according to the adjusted advertisement period, the service advertisement including one or more service IDs for identifying one or more services to be advertised from the local device.

Abstract: Methods and apparatuses for operating a wireless mobile station configured to communicate with a wireless access point are described. A first awake timer may be started in response to receiving a beacon signal from the wireless access point. The beacon signal may indicate that data is available or pending for the wireless mobile station. A second awake timer may be started in response to data received from the wireless access point. When the second awake timer expires, the wireless mobile station may return to the sleep state. In one embodiment, the first awake timer counts for a first period of time and the second awake timer counts for a second period of time which is shorter than the first period of time. The RF radio may be in a higher power state when the first and/or the second awake timers are counting. In one embodiment, the wireless mobile station and the wireless access points may be synchronized using target beacon transmission times of the beacon signal.

Abstract: A system and method are disclosed for decreasing the amount of power consumed by a wireless signal receiver in a wireless device. Received data is communicated from the receiver to a play-out buffer in communication with a media play-out device. The level of data in the play-out buffer increases when received data is written to the buffer, and the level of data decreases when data is read from the buffer. If the level of data is above a first watermark level, the receiver is transitioned to a sleep mode while data is read from the buffer. When the level of data in the buffer falls below a second watermark level, the receiver is transitioned back to an active mode to receive data. The device communicates status messages (whether the receiver is asleep or active) to the transmitting device so that the transmitting device stops transmitting data when the receiver is in sleep mode, and transmits data when the receiver is in the active mode.

Abstract: A first network device generates a first clock. A second network device transmits a plurality of frames in response to receiving a request from the first network device. A third network device generates a second clock, receives the plurality of frames, generates time stamps based on the second clock, and transmits a first signal including the time stamps. The first network device receives the plurality of frames, receives the first signal, generates a second signal based on the plurality of frames and the first signal, and transmits the second signal. The third network device synchronizes the second clock of the third network device to the first clock of the first network device based on the second signal received from the first network device.

Abstract: A local device broadcasts a first advertisement in a first wireless network via a first wireless interface, where the first advertisement includes one or more service identifiers (IDs) identifying one or more services being advertised and an availability schedule of the local device in the first wireless network. The local device broadcasts a second advertisement in a second wireless network via a second wireless interface. The local device scans in the first wireless network during an availability window of the availability schedule for a response to the first advertisement, where the broadcast of the second advertisement is disabled during the availability window.

Abstract: A local device broadcasts a service advertisement in a wireless network, where the service advertisement includes one or more service identifiers (IDs) identifying one or more services being advertised and an availability schedule of the local device. Optionally, the local device reduces power to at least a portion of the local device and wakes up at a time according to the availability schedule. The local device listens in the wireless network according to the availability schedule of the local device. In response to a service request received from a remote device during the availability window, the local device transmits a service response to the remote device. The service request includes one or more service IDs identifying one or more services being inquired by the remote device and the service response includes detailed information associated with one or more services identified by the one or more service IDs.

Abstract: Methods and apparatuses for operating a wireless mobile station configured to communicate with a wireless access point are described. A sleep state may be maintained in which a radio frequency (RF) radio in the wireless mobile station is in a low power state. The wireless station may use a plurality of sleep states, each with a different sleep timer period based upon recent network activity. In one embodiment, a device may have two sleep states with two sleep timers, and in another embodiment a device may have three sleep timers for three sleep states. The first sleep time may be started for a first sleep state and to determine when to awake the device to determine whether there is any network activity. The device then determines whether a first period of network inactivity has occurred and, if so, it starts a second sleep timer for a second sleep state in response to determining that the first period of network inactivity has occurred.
