Abstract: Systems, methods, devices, and computer program products are described for supporting macrocell-to-femtocell hand-ins of active macro communications for mobile access terminals. An out-of-band (OOB) link is used to detect that an access terminal is in proximity of a femtocell (e.g., using an OOB radio integrated with the femtocell or in a common subnet with the femtocell). Having detected the access terminal in proximity to the femtocell, an OOB presence indication is communicated to a femto convergence system disposed in a core network in communication with the macro network to effectively pre-register the access terminal with the femto-convergence system. When the femto convergence system receives a handoff request from the macro network implicating the pre-registered access terminal, it is able to reliably determine the appropriate target femtocell to use for the hand-in according to the pre-registration, even where identification of the appropriate target femtocell would otherwise be unreliable.

Abstract: An allocation technique is operable to allocate communication resources in multi-hop networks under the joint consideration of communication requirements and fairness. Embodiments operate to provide allocation of time slot resources in TDMA based multi-hop wireless networks under the joint consideration of QoS and fairness. Embodiments operate with respect to information regarding maximal common slot set flow contention. An iterative process is applied with respect to the information regarding maximal common slot set flow contention to allocate communication resources providing a balance between meeting communication requirements and fairness. According to embodiments, an inter-graph process iteratively selects a maximal common slot set for which resource allocation with respect to various flows is to be performed and an intra-graph process assigns communication resources in the maximal common slot set providing a balancing between meeting communication requirements (e.g., QoS) and providing fairness.

Abstract: Techniques for aggregating wireless communications are provided. These techniques include a method for aggregating wireless communications traffic in a femtocell. The method includes receiving at a femtocell a stream of data packets for a mobile device from a wireless router, selecting a transmission mode for sending data packets of the stream of data packets from the femtocell to the mobile device. The first transmission mode includes transmitting the data packets from the stream via a Long Term Evolution (LTE) interface of the femtocell. The second transmission mode includes transmitting the data packets from the stream via a WiFi interface of the wireless router. The third transmission mode includes transmitting a first portion of the data packets to the mobile device via the LTE interface and routing a second portion of the data packets to the wireless router for transmission to the mobile device via the WiFi interface.

Abstract: Methods, systems, and devices are provided for dynamically adapting the bandwidth of flexible bandwidth carriers. Adapting the bandwidth of a flexible bandwidth carrier may be achieved through changing the scale factor of the flexible bandwidth signal. Information such as traffic patterns, interference measurements, etc., may be utilized to determine the adapted scaling factors. In macrocellular deployments, for example, dynamically adjusting the bandwidth of a flexible bandwidth system may be utilized in order to increase network capacity, mitigate interference caused to other carriers, avoid adjacent carrier interference, and/or save energy on the network. Traffic pattern and other information may also be utilized to dynamically adjust uplink and downlink bandwidths of a flexible bandwidth carrier, either jointly or independently.

Abstract: Systems, methods, devices, and computer program products are described for handling of access terminals on an out-of-band piconet within a femto-proxy architecture. A femto-proxy system includes a femtocell (a femto access point, or FAP) and one or more out-of-band (OOB) proxies. One of the OOB proxies is configured to act as a master of an OOB piconet, through which various services are provided, including services to support the femtocell operation of the femto-proxy system. For example, the OOB piconet is used to facilitate lower power access to the macro communications services provided through the femtocell. In some cases, a combination of connected and inactive OOB operational modes are used to support an expanded number of slave access terminals on the piconet, where some of those slaves are operating in an active WWAN mode and others are operating in an idle WWAN mode. For example, parked mode may be used for idle WWAN mode access terminals.

Abstract: Methods, systems, and devices are provided that may support paging over a flexible bandwidth carrier. For example, a reduced paging capacity with respect to a target paging capacity for the flexible bandwidth carrier may be identified. The reduced paging capacity for the flexible bandwidth carrier may be mitigated by various techniques. One technique may include increasing a number of paging indicators sent per frame over the flexible bandwidth carrier. Other techniques may include reducing a Spreading Factor (SF) for a physical channel or a Secondary Common Control Physical Channel (SCCPCH) carrying the paging indicators over the flexible bandwidth carrier. Further techniques may include utilizing a plurality of paging channels, which may include utilizing a plurality of Paging Indicator Channels (PICHs) or a plurality of SCCPCHs. Other techniques may include reducing a paging area for at least the flexible bandwidth carrier and a normal bandwidth carrier.

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.

Abstract: Systems, methods, devices, and computer program products are described for supporting macrocell-to-femtocell hand-ins of active macro communications for mobile access terminals. A femto-proxy system is provided including a femtocell and an out-of-band (OOB) proxy. While the femtocell may be addressed by the macro network according to a potentially non-unique identifier (e.g., its PN offset), the OOB proxy is addressable according to a unique OOB identifier (e.g., a Bluetooth device address, BD_ADDR). When the mobile access terminal is in proximity to the femto-proxy system, it detects the OOB proxy and communicates the unique OOB identifier to the core network via the macro network (e.g., as part of a measurement report). The OOB identifier is mapped (e.g., in the core network) to the femtocell, allowing the core network to uniquely identify the appropriate target femtocell for active hand-in.

Abstract: Methods, systems, and devices are disclosed for providing data, such as voice data for a voice service, over flexible bandwidth carriers. Some embodiments include support for 12.2 kbps and/or 7.95 kbps AMR CS voice over flexible bandwidth UMTS (F-UMTS) in particular. Some embodiments provide for keeping the information data rate for a flexible bandwidth carrier at least the same as that of a normal bandwidth carrier. For example, one voice frame may still be mapped to a 20 ms time window upon transmission, irrespective of a flexible bandwidth scaling factor N or chip rate divider Dcr in F-UMTS. The tools and techniques provided may be implemented on mobile devices and/or base stations. Flexible bandwidths carriers may utilize portions of spectrum that may be too big or too small to fit a normal bandwidth waveform for a normal bandwidth carrier.

Abstract: Apparatus and methods are disclosed that provide various incentive schemes for owners of low-power base stations to allow others nearby to use their base station, enabling offloading of some users from a nearby macrocell, thus helping improve overall network performance. For example, a “win-win” scenario might exist when a sharing opportunity at a low-power base station overlaps with a sharing opportunity at the neighboring macrocell. During this overlap, when the low-power base station provides access to its air interface to one or more UEs outside of a set of UEs associated with the low-power base station, an incentive credit may be received. Incentive credits can take various forms, and in some examples, may be in an amount that is a function of an amount of contribution to the network resulting from the provision of access to the air interface.

Abstract: Methods, systems, and devices are provided that may address problems pertaining to effective transmit power control of a communications device operating in a wireless communications system. Some embodiments utilize mechanisms or techniques with dynamically adaptive steps sizes for transmit power control based on one or more trends. Some of these techniques may identify a trend in the transmit power control (TPC) commands and may adapt a TPC step size as a result. Other techniques may be utilized in which transmit power control is based on multiple interference estimates in a frame slot. Having multiple interference estimates at sub-slot intervals may provide additional transmit power control by allowing more transmit power adjustments, or more appropriate adjustments, for each slot. Metric calculations may be performed on one or more techniques to determine appropriate TPC operations.

Abstract: Methods, systems, and devices are provided that may enable wireless communications systems that utilize flexible bandwidths to transmit at the same or similar rates as wireless communications systems that utilize normal bandwidths. Some embodiments identify a target rate for a broadcast channel of a first bandwidth carrier system and transmit broadcast information utilizing the target rate. The target rate is higher than a scaled rate that results from scaling the rate for a broadcast channel of a second bandwidth carrier system by a bandwidth scaling factor. The first and second bandwidth carrier systems may be flexible and normal bandwidth carrier systems, respectively. To compensate for the bandwidth scaling and effectively maintain the rate at which information is transmitted in normal bandwidth carrier systems, different optimized schedules for system and master information transmission, different channelization codes and channels, and/or different scaled spreading factors may be identified and utilized.

Abstract: Apparatus and methods are disclosed for dynamically allocating an available bandwidth among different applications running at an access terminal operating in a wireless communication system that may be subject to certain bandwidth constraints. In particular, management of the allocation of resources when such resources are determined to be constrained may be implemented at the access terminal itself, for example, by reducing a requested bandwidth corresponding to at least one application flow from among a plurality of application flows. In this way, the superior information available to the access terminal regarding the demands and capabilities of the individual applications can be taken into account. Thus, multiple concurrently running applications competing for common limited resources may achieve a satisfactory level of service or QoS, resulting in an enhanced user experience.

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.

Abstract: A method of beacon detection performed by a small cell device includes: exchanging beacon parameters with a user equipment (UE); entering a low power mode after exchanging the beacon parameters with the UE; receiving, from the UE, a beacon in a random access channel (RACH) preamble containing the beacon parameters while in the low power mode; entering a high power mode in response to receiving the beacon; and associating with the UE while in the high power mode. The method of beacon detection allows a small cell device to transition from a low power mode to a high power mode in an efficient manner. The transmission may be triggered by a user equipment that is entering a service area of the small cell device.
