Abstract: An adjustable filter is responsive to a control signal to change a frequency response of the adjustable filter based on frequency spectrum information. The control signal may shift a center of the pass band from a first center frequency to a second center frequency and/or change a pass band bandwidth from a first bandwidth to a second bandwidth. In one example, the frequency spectrum information includes a status of an internal secondary radio. The frequency spectrum information may also indicate a region of operation where the frequency response is selected in accordance with the region.

Abstract: Methods, systems, and devices for wireless communication are provided for mobility management for wireless communications systems that utilize a flexible bandwidth carrier. Some embodiments include approaches for determining bandwidth information, such as one or more bandwidth scaling factors N and/or flexible bandwidths, at a user equipment (UE), where the bandwidth information may not be signaled to the UE. Embodiments for determining bandwidth information include: random ordered bandwidth scaling factor approaches, delay ordered bandwidth scaling factor approaches, storing bandwidth scaling factor value in UE Neighbor Record approaches, spectrum measurement approaches, spectrum calculation approaches, and/or a priori approaches. Flexible bandwidth carrier systems may utilize spectrum portions that may not be big enough to fit a normal waveform. Flexible bandwidth carrier systems may be generated through dilating, or scaling down, time, frame lengths, bandwidth, or the chip rate of the flexible bandwidth carrier systems with respect to a normal bandwidth carrier system.

Abstract: A receive (Rx) chain of a wireless local area network (WLAN) transceiver may be used to assist a wireless wide area network (WWAN) transceiver in a user equipment (UE). A UE may use the WLAN Rx chain to autonomously scan and measure while the UE is connected to a first or home wireless network using its WWAN transceiver. When the UE is in a connected state, the WLAN Rx chain may be used to scan and take measurements for one or more second networks operated by a second wireless operator belonging to the same mobile virtual network operator (MVNO) as the first wireless network. In another example, the WLAN Rx chain may perform a set of inter-frequency reference signal time difference (RSTD) measurements based on observed time offsets between positioning reference signals (PRSs) from neighboring cells.

Abstract: In a user equipment (UE) supporting multiple radio access technologies (RATs) and operating in an multiple-SIM multiple-active (MSMA) scenario, at least a portion of the wireless local area network (WLAN) transceiver may be used opportunistically to support the operation of the wireless wide area network (WWAN) transceiver to support the multiple subscriber identity modules (SIMs). For example, when a first SIM is in an active mode and using the WWAN transceiver for transmit and/or receive operations, at least a portion of the WLAN transceiver may be used in addition to the WWAN transceiver to support the WWAN operation of a second (or third, etc.) SIM. The WLAN transceiver may be used for transmit, receive, or both for the second SIM, while the first SIM continues to use the resources of the WWAN transceiver.
