    Abstract: Techniques are discussed for conveying frequency error characteristics for a plurality of cell transceivers from a server to a mobile device to enable the mobile device to determine an optimum or near optimum period of coherent integration of a downlink signal from one or more of the plurality of cell transceivers based on the frequency error characteristics. The coherent integration of the downlink signal may be to support a downlink terrestrial positioning method such as the Observed Time Difference of Arrival (OTDOA) method for Long Term Evolution (LTE) and the downlink signal may be a Positioning Reference Signal (PRS). A mobile device may perform downlink signal integration for longer periods than the optimum period for coherent integration by combining coherent integration results using non-coherent integration. The optimum period may achieve maximum or near maximum signal to noise ratio.

    Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) operating in discontinuous reception (DRX) mode receives a DRX configuration, receives a reference signal resource configuration, determines, at least based on the DRX configuration and the reference signal resource configuration, whether an overlap exists between a reference signal occasion of a plurality of reference signal occasions of the reference signal resource configuration and an active time of the DRX configuration, receives or transmits at least based on a determined overlap, at least a first reference signal in the reference signal occasion, and receives or transmits, while remaining in an active state of the DRX configuration, at least based on the determined overlap, at least a second reference signal in remaining reference signal occasions of the plurality of reference signal occasions after expiration of the active time.

    Abstract: One or more sequences of binary values may be generated based on a length L and a duty cycle D, wherein duty cycle D denotes a percentage of a number of bits of value one in length L. Then, based on an identity of a cell, a sequence may be selected for use by a base station in muting its transmission of a positioning signal. The sequence which is selected may be used directly in muting with no change therein, or may be elongated followed by use of an elongated sequence in muting. When specific occasions are muted in the positioning signal, a mobile device may measure times of arrival of other positioning signals that are not muted. Two such measurements of arrival times may be used to compute a difference there between, for use as a difference measurement in a procedure to determine a location of the mobile device.

    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: Methods, systems, computer-readable media, and apparatuses for crowdsourcing the synchronization status of a network are presented. In various embodiments, a server receives a synchronization status of a base station associated with the network. If the synchronization status indicates that the network is synchronous, the server collects information for computing time correction data. The server may send the time correction data to the mobile device for use in determining the position of the mobile device when the mobile device is connected to the synchronous network.

    Abstract: Determining the early arrival path (EAP) based on a channel energy response (CER) can involve the use one or more masks to identify one or more peaks in the CER. Masks can be applied to the CER in an iterative process that can help identify the earliest peak corresponding to the EAP. Alias cancelation may also be implemented.
