Abstract: Methods and apparatuses are described relating to changes in an antenna configuration of a multi-antenna radio frequency (RF) transceiver between reference signal occasions. In one set of examples, a first antenna configuration at a first reference signal occasion of a first RF transmitter is stored, and if the antenna configuration has changed by the time a second reference signal occasion of the first (same) RF transmitter begins, the antenna configuration is switched back to the first antenna configuration. In another set of examples, compensation data to enable compensation between the first antenna configuration used to measure a first reference signal of a reference RF transmitter and a second antenna configuration used to measure a second reference signal of a neighboring (different) RF transmitter is retrieved and used when computing a time difference between the first and second reference 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: 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: Techniques are provided for network mode selection based on positioning system information blocks (SIBs). An example method for measuring positioning reference signals with a user equipment includes receiving one or more system information blocks containing positioning reference signal information, determining band and frequency information for positioning reference signals based on the one or more system information blocks, determining at least one operational constraint for the user equipment, determining a network mode for the user equipment based at least on the band and frequency information and the at least one operational constraint, and measuring one or more positioning reference signals based at least in part on the network mode.

Abstract: Disclosed are techniques for performing positioning measurements at a mobile device during a positioning session with a serving cell. In an aspect, the mobile device determines to trigger a coverage-enhanced (CE) mode before a positioning session timeout for the positioning session expires, continues performance of the positioning measurements during the positioning session with the serving cell while the mobile device remains connected to the serving cell due to the triggered CE mode, determines whether the positioning measurements have been completed or the positioning session timeout has expired, and responsive to the determination that the positioning measurements have been completed or that the positioning session timeout has expired, reports, to a network entity in the wireless communications network, actual handover measurements to enable the network entity to make a handover determination.

Abstract: In techniques disclosed allow a user equipment (UE) that receives location assistance data to determine a preferred bandwidth part (BWP) with which reference signals from one or more base stations can be measured for position determination of the UE. The selection of the preferred BWP can be based on a determination of the frequency and bandwidth of reference signals to be transmitted by the one or more base stations over the course of a positioning station. The preferred BWP may be the BWP, of a plurality of candidate BWPs, that allows for a desired number of reference signal measurements to be taken without retuning a transceiver of the UE.

Abstract: A user equipment (UE) includes a processor configured to: send a first signal but not a second signal in response to the first and second signals being scheduled for concurrent transmission and available power for transmission of the first signal for the concurrent transmission being insufficient for detection of the first signal, the first signal being a first radio access technology (RAT) positioning reference signal; set a power sharing mode of the UE to a static power sharing mode; indicate that the UE is in a single-uplink operating mode with respect to the first RAT and the second RAT; and/or select a second-RAT TRP, for receiving the second signal, that has a maximum UE transmission power no greater than a threshold power in response to the initiation of the positioning session.

Abstract: Methods and techniques are described for enhancing positioning related protocols in order to indicate when one location session is different from another location session. One or more messages provided in a location session by a location server to a user equipment (UE) may include a session indication, such as a session identifier (ID), where a different session ID is provided for each location session. The session indication may be a new session indicator provided in an initial message in a location session or an end session indicator provided in a final message in a location session. An extra message may be sent by the location server indicating that the location session has ended. A correlation ID provided by a network entity to the location server may be included in messages as the session indication, e.g., where a different correlation ID is provided for each location session.
