Abstract: Transmit output power for an uplink (UL) positioning sounding reference signal (SRS) may be determined by measuring output power of a transmit chain of a user equipment (UE) during an unused RACH occasion. A transmit output power offset is determined based on a difference between the measured output power and a predetermined output power. The transmit output power offset may be used to adjust the power output of the UE.

Abstract: Techniques are provided which may be implemented using various methods and/or apparatuses in a mobile device to determine signal measurements on a plurality of frequencies and to provide signal measurements for position calculation on a location server or on the mobile device. Techniques are provided which may be implemented using various methods and/or apparatuses on a mobile device to concurrently scan for signals across two or more frequencies while optimizing sending and/or utilizing signal measurements made at higher frequency bands or signal measurements of signals sent from devices at a shorter range.

Abstract: A mobile device can send and receive signals in a dedicated frequency band and receive signals in a separate frequency band separate from the dedicated frequency band. The mobile device can send one or more frequency band compatibility combinations each including first and second frequency bands, the first frequency band being in the separate frequency band and the second frequency band being in the dedicated frequency. The mobile device can listen, based on a received neighbor list, for a first signal that has a frequency in the first frequency band and for a second signal that has a frequency in the second frequency band. The mobile device can determine, based on the first signal, ranging information indicative of a range from the mobile device to a source of the first signal, e.g., to obtain improved accuracy ranging information.

Abstract: Techniques are provided for use by an user equipment (UE) to perform an autonomous tune-away period of operation. The techniques allow the UE to transmit an indication of reception to a first base station during the autonomous tune-away period of operation during which the UE may be configured to receive signals from a second base station. The indication of reception may correspond to a signal transmitted or to be transmitted by the first base station during the autonomous tune-away period of operation. The indication of reception transmitted during the autonomous tune-away period of time may influence signals transmitted by the first base station after an end of the autonomous tune-away period of operation.

Abstract: Methods and systems are disclosed for concurrent transmission of resource blocks allocated to a mobile device for transmission in uplink communication channels. In particular implementations, a mobile device may tune local oscillators and/or apply filtering of radio frequency transmission to reduce or mitigate intermodulation distortion potentially affecting one or more radio frequency receiving functions.

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: Systems and methods are disclosed for improving Positioning Reference Signaling (PRS) measurements. A method comprises receiving an instruction at a user equipment (UE) to perform a PRS measurement on a target band, wherein the PRS measurement is an inter-frequency PRS measurement associated with a PRS measurement occasion, estimating, for each transceiver of a plurality of transceivers associated with the UE, and based on one or more transmit frequency bands thereof, interference with the inter-frequency PRS measurement, identifying a primary aggressor transceiver from among the plurality of transceivers, wherein the primary aggressor transceiver has a highest estimated interference, identifying an uplink transmission window associated with the primary aggressor transceiver, comparing the uplink transmission window to the PRS measurement occasion, selecting the identified primary aggressor transceiver as a selected transceiver in response to a determination that there is complete overlap between the uplink transmission window and the PRS measurement occasion, tuning the selected transceiver to the target band, and performing the inter-frequency PRS measurement with the selected transceiver.

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: Methods and systems are disclosed for obtaining a locus of an estimated location of a mobile device. According to an embodiment, a mobile device may obtain a plurality of timing advance parameters based, at least in part, on frames transmitted from the mobile device to a plurality of base stations on uplink channels to the plurality of base stations. A timing advance parameter may be selected from among the plurality of timing advance parameters to a particular base station of the plurality of base stations, wherein the particular base station is not a base station of a primary cell. The locus of the estimated location of the mobile device may then be determined based, at least in part, on a location of the particular base station and the selected timing advance parameter.

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.
