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 described herein are directed toward an enhanced LTE positioning protocol for multiple location reporting (with non-final and final fixes) that can be utilized by a user equipment (UE) to help prevent a disruption of the communication of information for a final location fix from the UE to a location server. In particular, techniques help ensure that the location server will not acknowledge receipt of the information provided by the UE in communication for a non-final fix.

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: A user equipment (UE) is preconfigured with Positioning Reference Signal (PRS) configurations for a plurality of base stations. The UE receives a base station almanac including position information and identifies of local base stations. Using the PRS configurations and information from the base station almanac, the UE receives PRS signals from a first set of base stations. The UE may also receive cell-specific reference signals (CRS) from a second set of base stations. The UE performs location determination for the user equipment using the PRS signals from the first set of base stations, the CRS signals from the second set of base stations.

Abstract: A mobile device is capable of enabling one or more location data sources for location determination of the mobile device. The mobile device may receive a request for an emergency location session, e.g., by a user dialing E911 or from an external client. At least one location data source in the mobile device is determined to be disabled. For example, the location data sources may be a WLAN transceiver or a WPAN transceiver, as well as camera sensors and environmental sensors. The disabled location data source (s) is enabled and location data is obtained from the enabled location data source(s). The location data may be provided, e.g., to a location server. The status of the location data source (s) may be restored, e.g., disabled, after the location data is obtained or after the emergency location session is completed.

Abstract: The location of a user equipment may be determined by having the user equipment use a radio carrier and/or a bandwidth part having the highest sub-carrier spacing available to the user equipment. A user equipment may communicate through a plurality of radio carriers, determine a first radio carrier or bandwidth part having a highest sub-carrier spacing, determine a timing advance value associated with the first radio carrier or bandwidth part, and transmit to a location server, the timing advance value.

Abstract: A user equipment (UE) is configured to be connected to a 5G New Radio (NR) network that shares one or more frequency bands using dynamic spectrum sharing (DSS) with a Long Term Evolution (LTE) network that is transmitting LTE positioning reference signal (PRS). The UE may receive LTE PRS rate matching information from the NR network, such as the LTE PRS configuration data or an LTE PRS rate matching pattern. The UE may decode and process NR data signals and control signals transmitted by the NR network while LTE PRS is transmitted by rate matching around the LTE PRS in accordance with the LTE PRS rate matching information. The LTE PRS muting pattern may be adjusted based on NR data or control signals, and the UE may receive and process NR data and control signals transmitted while the LTE PRS is muted.

Abstract: A user equipment (UE) enhances positioning performance using Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN) New Radio (NR)-Dual connectivity (EN-DC) based on an indication from the E-UTRAN base station that it is capable of EN-DC, e.g., in the upper layer indication of SIB2. When in idle mode, a UE that supports EN-DC and that has multiple carrier subscriptions may check the availability of EN-DC on both subscriptions that are camped on E-UTRAN base stations and use the subscription with EN-DC when a positioning session is initiated, e.g., from an emergency call. If one subscription is camped on a E-UTRAN base station and the other on an NR base station, the UE may use the E-UTRAN base station if EN-DC is supported or may use the NR base station if EONR and location based services are supported. A list of E-UTRAN base stations capable of EN-DC may be generated and used for selections of base stations to connect to or to prioritize during a handover procedure.
