Abstract: In an aspect, to perform inter-frequency measurements by a user equipment (UE) in a carrier aggregation mode, the UE receives assistance data identifying one or more reference signal occasions for one or more neighbor cells, receives information identifying one or more subframes during which the one or more neighbor cells do not carry data transmissions, identifies, for a first reference signal occasion of the one or more reference signal occasions, a first subframe of the one or more subframes that overlaps the first reference signal occasion, tunes, during the first subframe, a first active carrier receiver of a plurality of active carrier receivers away from a first frequency on which the first subframe is transmitted to a second frequency on which the first reference signal occasion is transmitted, and measures, by the first active carrier receiver, the first reference signal occasion on the second frequency during the first subframe.

Abstract: Techniques are provided to initiate signal transmissions for possible opportunistic reception by a mobile device, and/or to initiate opportunistic reception of signal transmissions for use in mobile device position location estimation. For example, a mobile device may use assistance data to identify a first signal to be transmitted over a first frequency band and a second signal to be transmitted over a second frequency band during a specific period of time. At least a portion of the second frequency band may be outside of the first frequency band. The mobile device subsequently attempts to opportunistically receive at least the first signal and the second signal via a receiver tuned to a reception frequency band that encompasses at least the first frequency band and the second frequency band. The mobile device may then process the opportunistically received signals to obtain measurements corresponding to at least the first and second signals.

Abstract: In various implementations, methods, apparatuses, and computer-readable media are described for optimizing tune away carrier selection in a wireless communications system for position determination. The selection of a tune away carrier can be based on, for example, timing information related to pre-scheduled periods for receiving wireless position measurement signals, timing information related to pre-scheduled downlink data reception, timing information related to pre-scheduled uplink data transmission, etc.

Abstract: Techniques for determining a position of a mobile device are provided. A method according to these techniques includes obtaining assistance data comprising information for cells associated with a plurality of wireless transmitters of a wireless communications network based on the coarse location of the mobile device, selecting a plurality of the cells from the assistance data, wherein selecting the plurality of cells includes identifying sets of colocated cells and selecting one cell from each of the colocated sets of cells; measuring signals from the plurality of cells to generate positioning signal measurements; and sending the positioning signal measurements to a location server. A colocated set of cells may include a narrowband cell and a non-narrowband cell, and the narrowband wireless cell may comprise a narrowband Internet of Things (NB-IoT) cell and a non-narrowband cell colocated with the NB-IoT cell at an Evolved Node B (eNodeB).

Abstract: Disclosed are devices and processes for processing portions of a downlink signal using multiple receive chains. In one implementation, while message traffic is received at two or more receive chains of a receiver device, an inactivity timing may be initiated following a most recent activity event at the receiver device. Responsive to a request to acquire a portion of a downlink signal at the receiver device following initiation of the inactivity timer, at least one of the two or more receive chains may be scheduled to acquire the portion of the downlink signal. Other, unscheduled receive chains may be transitioned to a lower power state upon expiration of the inactivity timer.

Abstract: A method for performing inter-frequency positioning measurements on positioning signals periodically transmitted by at least some of a plurality of cells in a wireless communication network is provided. The method includes receiving, at a mobile device, assistance data that identifies a first neighbor cell the plurality of cells, where the first neighbor cell transmits a first positioning signal. The method also includes obtaining a first cell property of the first neighbor cell. The mobile device then adjusts a duration of a first measurement gap in response to the first cell property. In one aspect, the first measurement gap corresponds to a time period during which the mobile device is to perform positioning measurements of the first positioning signal.

Abstract: A mobile station that is wirelessly linked to a wearable device, receives a request to initiate a location session from the wearable device, e.g., which may be in the form of an emergency call. The mobile station determines whether the location of the mobile station may be used as a location of the wearable device, e.g., by determining if the wearable device is proximate to the mobile station. For example, the mobile station may check to see if the mobile station is wirelessly linked to a wearable device through a wireless personal area network (WPAN). The mobile station initiates the location session for the wearable device with a location server. If the location of the mobile station may not be used as a location of the wearable device, the location session for the wearable device does not use position information obtained from the mobile station.
