    Abstract: Techniques for supporting positioning for a terminal (sometimes referred to herein as a target device) in a wireless network are described. In an aspect, positioning for a target device includes receiving a Request Location Information message that indicates at least one positioning method from a plurality of supported positioning methods. The Request Location Information message comprises common parameters that are applicable to all positioning methods indicated in the Request Location Information message. The common parameters comprise a quality-of-service (QoS), an indication of whether periodic location information is requested, an indication of whether triggered location information is requested, or any combination thereof. Positioning is performed in response to the Request Location Information message and can include determining a location estimate for a location of the target device.

    Abstract: Methods, systems, and devices for wireless communications are described. The described techniques relate to improved methods, systems, devices, and apparatuses that support aperiodic and cross component carrier PRSs. Generally, the described techniques provide for receiving a dynamic trigger indicating that a UE is to monitor for one or more downlink positioning reference signals (PRSs). The UE may generate a timing measurement for the one or more downlink PRSs, and may transmit a measurement report that indicates the timing measurement to a transmission/reception point. A UE may also transmit a capability indicator, indicating that the UE is capable of maintaining phase coherence for a PRS that spans multiple component carriers, receive control signaling that indicates multiple component carries on which the PRS is phase coherent, generate a timing measurement for the PRS based on the control signaling, and transmit a measurement report that indicates the timing measurement to the transmission/reception point.

    Abstract: Mobile devices often use orthogonal frequency division multiplexing (OFDM) to calculate position information of mobile devices within the network. However, physical distance between the mobile device and a signal source for positioning and other environmental factors can influence the signal strength of received signals. Received signals at the mobile device that are stronger may drown out the weaker signals, particularly when two signal sources occupy the same symbol. In traditional OFDM, a signal source transmits the same symbol for each positioning occasion, so a weaker signal may never be detected over a stronger signal, reducing the accuracy of the positioning calculations. Described herein are systems and methods for using a pattern to vary the designated symbol for each signal source in a wireless network so that a weaker signal from a signal source may be detected on at least some of the positioning occasions.

    Abstract: Disclosed are methods and systems for broadcasting positioning assistance data (PAD) to subscriber devices in a wireless network. In one aspect, a location server may encode and optionally cipher PAD and transfer the encoded and optionally ciphered PAD to a base station for broadcast in a system information block (SIB) in at least one cell. In an aspect, the PAD may be segmented by the location server or by the base station with each PAD segment broadcast in a separate SIB. Cipher key information for ciphered PAD may be transferred by the location server to a network node and provided to a subscriber device using a mobility management procedure. A subscriber device may receive, optionally decipher and decode PAD in SIBs broadcast by a base station and may use the PAD to assist location of the subscriber device.

    Abstract: Techniques described herein provide ways in which a quantity of signaling may be limited between a user equipment (UE) and a location server (LS) for a location session and a positioning protocol such as LPP or LPP/LPPe. The positioning protocol may be enhanced to allow the LS to indicate to the UE a limit on the overall size of assistance data (AD) that the UE can request and/or a limit on the overall amount of location information (LI) that the UE can return. A recipient UE can then prioritize any request for AD such that more important AD should fit within the size limit. The recipient UE can also prioritize returned location measurements such that more useful measurements are included in a message to the LS that is compliant to the limit indicated by the LS.

    Abstract: A method for use in determining a position of a mobile device in a wireless communication network includes acquiring, by the mobile device, a first positioning signal transmitted at a first frequency and a second positioning signal transmitted at a second frequency that is different than the first frequency. The mobile device performs a first measurement of a time difference of arrival between the first positioning signal and the second positioning signal. In certain implementations, in response to a determination to not apply an inter-frequency bias compensation to the first measurement for inter-frequency related delays corresponding to the first frequency, the second frequency, or both the first frequency and the second frequency, the mobile device sends the first measurement and a first measurement description to a server to determine the position of the mobile device. The first measurement description indicates that the first measurement has not been compensated for the inter-frequency related delays.
