    Abstract: A method for adaptive filtering of cell measurements is provided. The method can include a wireless communication device determining based on instantaneous measurement samples of a cell captured over a measurement period that a fading condition of the cell exceeds a threshold. The method can further include the wireless communication device modifying a network configured filter coefficient to derive a modified filter coefficient in response to the fading condition of the cell exceeding the threshold over the measurement period. The method can additionally include the wireless communication device filtering the instantaneous measurement samples based on the modified filter coefficient to calculate a filtered measurement of the cell. The method can also include the wireless communication device calculating an adjusted measurement value for the cell based on the filtered measurement. The method can further include the wireless communication device using the adjusted measurement value for event evaluation and reporting.

    Abstract: This disclosure relates to techniques for estimating baseband power consumption and using the baseband power consumption estimation to select baseband operation features. According to some embodiments, one or more baseband power consumption modifiers occurring during an estimation window may be identified. Baseband power consumption of the wireless device during the estimation window may be estimated based on the identified baseband power consumption modifiers occurring during the estimation window. Baseband data throughput of the wireless device during the estimation window may also be estimated. One or more baseband operation characteristics may be selected based at least in part on the estimated baseband power consumption during the estimation window, possibly in conjunction with the estimated baseband data throughput during the estimation window, current wireless medium conditions, and/or other considerations.

    Abstract: Embodiments are presented herein of techniques for a mobile device to control timing of inter-RAT handovers. In some embodiments, an apparatus includes one or more processing elements configured to execute an interactive wireless communication application using a wireless communication configuration between the apparatus and a communications network for a first RAT. In some embodiments, the wireless communication configuration does not have a QoS guarantee. In some embodiments, the apparatus is configured to store information from the communications network that specifies one or more wireless thresholds relating to handover from the first RAT to a second RAT. In some embodiments, based on executing the application and current wireless conditions, the apparatus is configured to send a report to a base station of the communications network, prior to at least one of the thresholds being met, to trigger a handover from the first RAT to the second RAT.

    Abstract: A method, station and computer readable storage medium used for setting a power level of the station. The station implements a first processing layer that is a radio link control layer and a second processing layer that is a physical layer. The method includes receiving data units of a voice application, the data units being in a sequence, determining whether the first processing layer of the station detects a gap in the sequence of received data units, communicating an indication from the first processing layer to the second processing layer, the indication indicating at least one identity of corresponding missing data units in the gap relative to the first processing layer and increasing the current power level when the at least one identity of the corresponding missing data units relative to the first processing layer is also determined to be a missing data unit relative to the second processing layer.
