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: Methods, systems, and devices are described that provide for parameter adjustment for devices. A device may register a user profile associated with a user. During registration an image of the user may be captured and analyzed, such as to determine a size of facial features for the user. Also, during registration, metrics may be input or determined such as the age of the user or any sensory sensitivities. The device may capture a second image of the user. The second image may be compared to the first in order to determine the current distance between the user's face and the device. Comparing the first and second image may include comparing the size of corresponding facial features in each image, such as measured in pixels. Multiple images may be used for the first or second images. Based on contextual conditions and the distance, the device may adjust a sensory-related parameter.

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.
