  • Publication number: 20130114473
    Abstract: Methods, systems, and devices for separating signaling data and traffic data onto separate carriers for wireless communications systems are provided. Some embodiments utilize flexible bandwidth that may utilize portions of spectrum that may not be big enough to fit a normal waveform through utilizing flexible waveforms. Flexible bandwidth systems may lead to reduced data rate on the signaling or other channels. Separating the signaling and the data traffic into different flexible bandwidth carriers so that assigned resources can be customized to different traffic patterns may address this issue. In some embodiments, the signaling data is received and/or transmitted over a first carrier separate from any other traffic data. For example, the signaling data may be received and/or transmitted over the first band carrier without any other traffic data. The traffic data and/or network data associated with the signaling data may be received and/or transmitted over a separate, second carrier.

  • Publication number: 20130114436
    Abstract: Methods, systems, and devices for increasing reverse link throughput by coordination of multiple wireless systems using reverse link blanking are provided. Some embodiments involve utilizing the bandwidth of one carrier bandwidth that partially overlaps with the bandwidth of another carrier bandwidth. This overlap may create interference. Different indicators may be utilized to prompt a device, such as a mobile device, to coordinate reverse link transmission blanking on at least one of the carrier bandwidths to increase throughput for the other overlapping carrier bandwidth. For example, a base station may transmit such an indicator to the mobile device to prompt the transmission blanking. Some embodiments also include increasing transmission power for the overlapping carrier bandwidth during the transmission blanking of other carrier bandwidth. Some embodiments utilize flexible carrier bandwidths systems that may utilize portions of spectrum that may not be big enough to fit a normal bandwidth waveform.

  • Publication number: 20130099920
    Abstract: One feature includes a mobile device being used as a mobile beacon and proxy for a tracking device that may track an object, such as a pet. The mobile device may act as a beacon that transmits messages over a short range communications link to the tracking device. If the tracking device fails to receive the messages transmitted by the mobile device, it may be assumed that the pet has gone missing, and in response the tracking device may contact a tracking server with its location information via a wireless wide area network (WWAN). Additionally, the mobile device may act as a proxy of the tracking device by transmitting and receiving data to/from the tracking server using its own communication interface on behalf of the tracking device. This helps conserve the battery power of the tracking device because the tracking device does not use its own WWAN interface.

  • Patent number: 8427975
    Abstract: Systems, methods, devices, and computer program products are described for using communications over an out-of-band (OOB) link to support compressed mode communications by user equipment (UE) in a femto deployment. Typically, UEs must tune away from an active communications channel to make inter-frequency and/or inter-RAT measurements. When making these measurements, data communications may be compressed to allow time to tune away for those measurements. Embodiments integrate an OOB proxy with the femtocell to provide OOB link capability to supplement WWAN link resources. According to various techniques, the OOB link is used to compensate for reductions in data rate and/or quality resulting from compressed mode operation. For example, the OOB link is used to communicate compressed mode signaling data, retransmissions, and/or other compensatory data.

  • Publication number: 20130059592
    Abstract: Methods, systems, and devices are described for femtocells to retrieve neighboring macrocells' timing information, using messages from mobile devices that are associated with the relevant macrocell In some cases, detection of the femtocell, such as through an out-of-band detection, may trigger the mobile device to determine timing information with respect to the macrocell and/or the femtocell. In some embodiments, the mobile device associated with the macrocell may be in active state and looking for a candidate femtocell for handover. The femtocell may receive this timing information from the mobile device and utilize it to synchronize with the neighboring macrocell. Embodiments may address fine timing synchronization and tracking for asynchronous and quasi-synchronous wide-area wireless networks (e.g., 3GPP/3GPP2 variants like UMTS, LTE, CDMA 1x, 1x EV-DO, etc).

  • Publication number: 20120322466
    Abstract: Systems, methods, devices, and computer program products are described for using an out-of-band (OOB) radio integrated with the femtocell to implement various novel proximity detection techniques. Proximity detection of access terminals (ATs) in the femtocell's access control list (ACL) can be desirable to support femto connectivity and service provision, for example, in context of idle macro-to-femto handoffs, active macro-to-femto hand-ins, etc. Implementations implement OOB proximity detection through multicasting directed proximity request messages to each AT in a femtocell's ACL. Responses to the proximity request message can include identification information used to determine the specific AT that is in proximity.

  • Patent number: 8335175
    Abstract: Proxy devices simultaneously support multiple modes of client device operation. Embodiments facilitate continued support of idle mode, proxy state operation of one or more client devices by a proxy device that is serving an active connected mode proxied client device. Paging message delivery from the proxy device to an idle mode proxied client device is facilitated by the proxy device monitoring a channel associated with the active connected mode proxied client device for a message (e.g., paging message) associated with the idle mode proxied client device.

  • Publication number: 20120244869
    Abstract: Methods, systems, devices, and computer program products are described for network scaling. In one example, candidate cells may be selected and ranked. For an initial assessment, the selected cells may operate at a significantly reduced power, and the network performance may be evaluated. Based on the results, only a subset of the candidate cells may be switched off. The whole process may be repeated until all the candidate cells are evaluated. Network downscaling may be done at a site level, a sector level, or a hybrid (site level first, and then additional downscaling by sector level).

  • Publication number: 20120182965
    Abstract: Systems, methods, devices, and computer program products are described for mitigating macrocell interference during femtocell discovery in a wireless communications system. In one example, a mobile device may be camped on a macrocell. A femtocell transmits out-of-band (OOB) discovery signals to, or receives OOB band discovery signals from, the mobile device to facilitate presence detection. The femtocell may also be configured to use various techniques to transmit in-band beacon bursts (e.g., low or high power beacon bursts) to the mobile device in the macrocell frequency range to trigger the mobile device to perform an inter-frequency scan for cell reselection. The femtocell may transmit communications signals to the mobile device in a femtocell frequency range (different from the macrocell frequency range) after the mobile device has discovered and selected the femtocell.

  • Publication number: 20120122511
    Abstract: A power conservation scheme is provided for conserving power in an access terminal that includes a dedicated proxy circuit, a receiver/transmitter chain, and/or a baseband processor. The baseband processor is adapted to determine when a wireless communication link with an access network has been inactive for at least a threshold amount of time. If such inactivity is ascertained, the baseband processor sends a proxy request to the proxy circuit. Upon receiving such proxy request, the proxy circuit monitors a data, control, and/or paging channel on behalf of the access terminal while the baseband processor is powered down. If a signal is received for the access terminal over the monitored channel, then a wake-up signal is sent to the baseband processor to cause it to power up and monitor a data channel. Upon receiving a response from the baseband processor, the proxy circuit may stop operating as a proxy.

  • Publication number: 20120120858
    Abstract: A novel power conservation scheme is provided for conserving power in a wireless client terminal with an established communication session. While in a connected mode, the client terminal may receive data for the communication session via a data channel from an access point. During periods of inactivity over the data channel, the client terminal may switch to a lowered power mode, where the client terminal discontinuously monitors a control channel and does not monitor the data channel. The access point is informed of the operating mode of the client terminal. If a data resume indicator is received over the control channel, the client terminal switches back to the connected mode and resumes the communication session by receiving additional data over the data channel.
