摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A scheme is provided for conserving power in client terminals and/or reducing latency in wireless systems by using a proxy device. The client terminal may have a primary communication interface for communications with an access node and a secondary communication interface to communicate with the proxy device. The client terminal may indicate to the access node a short cycle rate for monitoring its signaling/control channel(s). The client terminal may the power off its primary communication interface without informing the access node. Prior to powering off its primary communication interface, the client terminal may assign the proxy device to act as its proxy and monitor the signaling/control channel with the access node. The proxy device monitors the signaling/control channel(s) according to the indicated short cycle rate. Upon detection of a message for the client terminal, the proxy device forwards the message to the client terminal via a secondary communication interface.

摘要： Methods, systems, and devices are described that may provide for femtocells to indicate the proximity of mobile user equipments and/or provide mobile identity to assist in resolving femtocell disambiguation. A femtocell may detect a user equipment in its proximity using an out-of-band link. The femtocell may transmit a proximity indication message to a macro network controller via a core network. The macro network may direct the user equipment to perform a variety of tasks, including directing the user equipment to do a handover to the femtocell. Some embodiments may utilize existing user equipment registrations and femto-to-macrocell outbound handover procedures to address problems such as femtocell ambiguity resolution and triggering frequency searches at a macro network when a current macrocell signal strength is good. These embodiments may utilize dummy identifiers to register the user equipment to facilitate addressing these problems.

摘要： 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.
