    Abstract: Techniques described herein may enable more accurate location of a user equipment (UE) that may be subject to movement or velocity. The UE may obtain, during a period of time, location-related measurements of RF signals received at the UE, where the location-related measurements are indicative of a location of the UE during the period of time; The UE may also obtain, using sensors of the UE, velocity-related measurements indicative of a movement or velocity of the UE during the period of time. The UE may send the location-related measurements and the velocity-related measurements to a location server, which may compute a location of the UE based on the measurements. The location computation may allow for movement of the UE during the period of time.

    Abstract: Various embodiments in the disclosure provide methods implemented by a processor executing on a mobile communication device to dynamically determining whether the power saved by powering down the RF chain between the end of the last reception activities and the beginning of the next reception activities will exceed the power expended to reinitialize the RF chain's components and registers for the next reception activities. Based on this determination, the device processor may configure the RF chain either to power down fully, as in conventional implementations, or to enter a low-power mode in which power is maintained to the power rails supplying the memory registers storing RF communication data, thereby avoiding the power surge of restarting the registers and part of the power drain associated with writing the communication data back into the registers. In some embodiments, the mobile communication device may be a multi-SIM device.

    Abstract: Methods and devices address managing synchronization of a radio resource control (RRC) state on a wireless communication device having a radio frequency (RF) resource supporting receive activity of two radio access technologies (RATs). When a first protocol stack is in an RRC connected state, a tune-away of the RF resource is performed for the second RAT, and a media access control layer inactivity timer on the first protocol stack has not expired, the wireless device may determine whether a new resource grant is received from the network of the first RAT ifthe first protocol stack is operating in a connected discontinuous receive mode. If so and the first protocol stack's operational RRC state potentially differs from a corresponding RRC state set in the first RAT network, the wireless device may send a scheduling request to the first RAT network and select a page decode mode for the first protocol stack based on the response of the first RAT network.
