Abstract: An apparatus for wireless communication obtains a first metric of a cell based on signals received by a WWAN radio tuned to a common frequency, and a second metric of the cell based on signals received by a WLAN radio tuned to the common frequency. The apparatus determines a calibration factor based on the first and second metrics, and performs cell search and cell measurement based on the calibration factor and signals received by the WLAN radio tuned to a target frequency. The common frequency may be a serving frequency of the WWAN, in which case the first and second metrics are one of frequency or power metrics and the calibration factor is one of a frequency offset and a power offset. The common frequency may also be a target frequency for inter-frequency measurements of the WWAN, in which case the calibration factor is based primarily on power measurements.

Abstract: A method for wireless communications includes reducing transmission power, by a femto base station, at its radio frequency (RF) transmitter, and cancelling a transmitted data signal of the RF transmitter at its network listen (NL) receiver. The reduction occurs in response to: occurrence of a network listen process; and/or a signal quality of the local macro coverage area exceeding a threshold quality. Additionally or alternatively, the femto base station may detect quality of its macro coverage area, and respond to the signal quality being below the threshold quality by: suspending reduction of transmission power and cancellation of the transmitted data signal; suspending the RF transmitter during transmission gaps assigned to user equipments (UEs); and triggering an NL operation in response to suspension of the RF transmitter, wherein the NL operation occurs within the duration of each of the transmission gaps.

Abstract: Methods, systems, and devices for facilitating mobility between flexible bandwidth systems and other bandwidth systems are provided. These tools and techniques that provide mobility between different bandwidth systems may facilitate supporting circuit-switched (CS) services, such as CS voice services. Some embodiments provide for determining flexible bandwidth capable devices, such as user equipment. Some embodiments involve core network redirection where a core network may direct the handling of circuit-switched services when a flexible bandwidth system does not support the CS services. Some examples provide for radio access network determined handling of CS services when a flexible bandwidth system may not support the CS services. Some embodiments provide for transitioning to a flexible bandwidth system. Some embodiments provide for transitioning from flexible bandwidth systems to non-flexible bandwidth systems that have no support for some or all CS services, other flexible bandwidth systems, and/or systems that natively support CS voice services.

Abstract: Methods, systems, and devices are provided that may address problems to enabling a user equipment (UE) in connected mode on a normal bandwidth cell to make inter-frequency measurements on another normal bandwidth cell and a flexible bandwidth cell. Some embodiment utilize a set of compressed mode gap configurations for measuring both normal bandwidth and flexible bandwidth inter-frequency cells with the following modification for flexible bandwidth cells: reducing the coherent length used by the UE; using the same cell search parameters at the UE but modifying the compressed mode gap parameters to accommodate both normal bandwidth and flexible bandwidth cell search; and/or maintaining the compressed mode gap parameters but reducing the search window size during cell search coherent accumulation. Some embodiments may configure separate compressed mode measurements configuration for normal bandwidth and flexible bandwidth measurements.
