  • Publication number: 20130235750
    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: 20130225165
    Abstract: Scanning for femto access points includes scanning out-of-band (OOB) channels to discover OOB signals associated with the femto access point. When a femto access point is first discovered, a first type of scan is performed of each of the OOB channels. The user equipment (UE) determines whether any received responses originate from femto OOB access points and, if so, updates a search database of the UE. During subsequent visits to the area of the femto OOB access points, when the UE detects entry to a fingerprint area of the femto OOB access point, a second type of scan is performed, in which each of the OOB channels with femto OOB access points identified in the search database are scanned. If responses are detected to this second type of scan, a proximity indication is transmitted using in-band signals to a serving macro access point.

  • Publication number: 20130217385
    Abstract: Management of user equipment (UE) proximity indications to femto access points is provided using out-of-band (OOB) signals. To obtain OOB identification information on the femto access point, the UE determines the OOB identification information when in proximity to cells neighboring the femto access point. This OOB information is stored in a search information database (SID) of the UE and related to in-band information on the femto access point. To later determine proximity to the femto access point, in response to detecting its presence within a fingerprint area around the femto access point, a search for the femto access point is triggered using the OOB radio resources and OOB identification information associated with the femto access point in the SID. When the UE detects the femto access point using the OOB radio resources, the UE transmits a proximity indication to its serving base station over the in-band radio link.

  • Publication number: 20130182655
    Abstract: Methods, systems, and devices for utilizing flexible bandwidth carriers for small cells are provided. Bandwidth scaling factor(s) for a small cell may be determined. A flexible bandwidth carrier may be generated for the small cell utilizing the bandwidth scaling factor. Some embodiments provide assistance with active hand-in due to more available PN offsets in the flexible bandwidth domain. Some embodiments enhance small cell discovery with high bandwidth scaling factor beacon-like small cells with little more power than that corresponding to the same power spectral density for normal bandwidth small cell. Some embodiments reduce the interference caused by small cell to macrocell users using an adaptive bandwidth scaling factor for small cells based on number of users supported and their traffic demand, to control the extent of overlap the macrocell has with small cell and the interference to macrocell mobiles.

  • Publication number: 20130137423
    Abstract: A multi-mode access point supports multiple radio access technologies (e.g., Wi-Fi and cellular) and allocates access to the radio access technologies for various access terminals. To provide improved service for access terminals that are a member of a group associated with the access point, the access point may give priority access to member access terminals as compared to non-member access terminals. For example, the access point may give member access terminals exclusive access to one radio access technology, while giving non-member access terminals access to another (e.g., shared) radio access technology. As another example, the access point may provide a higher level of service for member access terminals on at least one type of radio access technology, while providing a lower level of service for non-member access terminals on the at least one type of radio access technology.

  • Patent number: 8442475
    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.
