According to embodiments, an example method for positioning an intelligent reflecting surface (IRS) using a transmitting device in a wireless communications network may comprise configuring the IRS to reflect a wireless reference signal back to the transmitting device and subsequent to configuring the IRS, transmitting the wireless reference signal from the transmitting device to the IRS. The method may also comprise receiving a wireless reflected signal at the transmitting device, wherein the wireless reflected signal comprises a reflection of the wireless reference signal, reflected by the IRS and determining measurements configured for positioning the IRS based at least in part on the wireless reflected signal, wherein a location of the IRS is determined based on the measurements.

Positioning of an intelligent reflecting surface (IRS) in a wireless communication network

According to embodiments, an example method of positioning a user equipment (UE) by a location server in a wireless communications network, the method may comprises receiving a request to perform positioning of the UE and receiving a notification from a first base station indicating that a transmission path between the first base station and the UE is via an intelligent reflecting surface (IRS). The method may further comprise responsive, at least in part, to receiving the notification, preventing the positioning of the UE from being based on a reference signal transmitted through the transmission path between the first base station and the UE.

UE positioning in the presence of an intelligent reflecting surface (IRS)

Positioning of a UE is supported in a Radio Resource Control (RRC) Inactive state. The UE receives a request for periodic or triggered location and enters the RRC Inactive state. When an event is detected, the UE sends an RRC Resume Request to a gNB that includes an indication of the event. The indication may be an event report that may include downlink positioning measurements. The gNB forwards the event report to a location server, and may later receive and return an event report acknowledgement to the UE in an RRC Release. The indication may instead trigger uplink positioning, with the base station sending an uplink Sounding Reference Signal (SRS) configuration to the UE in an RRC Release, causing the UE to transmit uplink SRS signals to be measured by gNBs. For uplink related position methods like RTT, the gNB can receive both types of indication.

A server may obtain wireless network coverage information from crowdsourcing devices, where the wireless network coverage information indicates characteristics of wireless network coverage at different locations along various routes of travel. The server may determine a wireless coverage map of an area based on the wireless network coverage information, where the wireless coverage map comprises, for locations along one or more routes of travel within the area, a respective wireless coverage indication indicative of a level of wireless coverage for wireless networks at the respective location. The server may send route-based coverage information to a mobile device for a particular route, where the route-based coverage information includes the respective wireless coverage indication, from the coverage map, for one or more locations along the particular route.

Determination of wireless coverage for a mobile device using a route based coverage map

Certain aspects of the present disclosure provide a method of wireless communication by a user equipment (UE). The method generally includes performing a mobility procedure to establish a connection in a target radio access technology (RAT) while maintaining a context established in a source RAT, wherein one of the source RAT or target RAT is a terrestrial network (TN) RAT and the other is a non-terrestrial network (NTN) RAT and sending a tracking area update (TAU) request after establishing the connection in the target RAT.

Handover between terrestrial network and nonterrestrial network

Techniques are provided for positioning of a mobile device in a wireless network using directional positioning reference signals (PRS), also referred to as PRS beamforming. In an example method, a plurality of directional PRSs are generated for at least one cell for a base station, such that each of the plurality of directional PRSs comprises at least one signal characteristic and a direction of transmission, either or both of which may be distinct or unique. The plurality of directional PRSs is transmitted within the at least one cell, such that each of the plurality of directional PRSs is transmitted in the direction of transmission. A mobile device may acquire and measure at least one of the directional PRSs which may be identified using the associated signal characteristic. The measurement may be used to assist position methods such as OTDOA and ECID and to mitigate multipath.

Systems and methods to facilitate location determination by beamforming of a positioning reference signal

Uplink high efficiency location of a user equipment (UE) includes initiating periodic or triggered location in the UE by a location server (LS) in a wireless network. The UE enters an idle state and monitors for triggering events. After detecting an event, the UE transmits an uplink positioning signal (UPS) to a base station, where the UPS encodes UPS data comprising a UE ID, an ID for the LS, an authentication code (AC) and location measurements. UPS transmission occurs in an uplink positioning occasion shared with other UEs. The location measurements may be ciphered but other UPS data is unciphered. The base station obtains additional location measurements and transfers the UPS data and the location measurements to the LS. The LS authenticates the UE ID using the AC, determines the UE location using the location measurements and transfers the location to an external client.

Systems and methods for uplink high efficiency location in a wireless network

A method of wireless communication performs a public land mobile network (PLMN) search for a higher priority PLMN. The PLMN search includes a candidate PLMN having a different mobile country code (MCC) than a serving PLMN. The method switches to the higher priority PLMN when the PLMN search locates the higher priority PLMN. A method determines whether a user equipment (UE) has transitioned between an international area and a national area. The method triggers PLMN selection in response to the UE having transitioned between the international area and the national area.

Wireless network selection in international areas

Disclosed are techniques for determining round-trip times (RTTs) between a user equipment (UE) and multiple base stations. In an aspect, the UE transmits an RTT measurement signal whose arrival time is measured by each of the base stations, and each of the base stations returns an RTT response signal whose arrival times are measured by the UE. In another aspect, the base stations each transmit an RTT measurement signal and the UE returns an RTT response signal. The receiver of the RTT measurement signal may include the measured arrival time in a payload of the RTT Response signal. Alternatively, the measured arrival time(s) of the RTT Measurement signal(s) and the transmission time(s) of the RTT Response signal(s) are sent in a separate message. The RTT signals can be wideband signals using low reuse resources.

Systems and methods for multiple round trip time (RTT) estimation in wireless networks

Methods and techniques are described for supporting location services for a user equipment (UE) that is using Narrowband Internet of Things radio access or Cellular Internet of Things features to access a wireless network. The techniques include enabling support for a last known location of a UE, using previously obtained location measurements, when a UE is not reachable from a wireless network for positioning. The techniques also include limiting positioning protocol interaction between a UE and a location server via a reduced maximum message size, reduced message volume and longer response and retransmission timers. The techniques further include enabling a UE to obtain location measurements when not connected to a wireless network, enabling periodic and triggered location of a UE in which a UE evaluates location triggers while not connected to a wireless network, enabling use of deferred location and enabling improved location security.

Methods and systems for support of location for the internet of things

During a positioning session between a user equipment (UE) and a location server, the location server may send the base station a request to suspend the Radio Resource Control (RRC) connection with the UE. For example, the location server may send a request to the base station recommending suspension of the connection or may provide an indication of the amount of time during which position related messages between the UE and the location server are not expected. The base station may determine whether to suspend the connection with the UE, thereby placing the UE in an inactive state based on the information provided. The base station may further determine whether to suspend the connection based on data activity of the UE. While in an inactive state, the UE and base station store UE connection context, which may be used to quickly resume the connection.

System and methods for power efficient positioning of a mobile device

Positioning of a UE is supported in a Radio Resource Control (RRC) Inactive state. The UE receives from a location server a request for periodic or triggered location and an indication of whether uplink, downlink, or uplink and downlink positioning will be used for subsequent location reporting events when the UE is in the RRC Inactive state. When an event is detected, the UE sends a first event report and a second event report to the location server to report the event and enable UE location while the UE is in the RRC Inactive state. The event reports are each sent with Small Data Transmission (SDT). The first event report may include a Request Assistance Data message indicating a request for an uplink (UL) Positioning Reference Signal (PRS) configuration and the second event report may include location measurement performed by the UE.

Method and apparatus for positioning of a user equipment in an inactive state

Techniques are provided for enabling on-demand positioning reference signals (PRS) with a user equipment (UE). An example method for determining a location of a mobile device includes sending a request for downlink positioning reference signals to a network server, where the request includes positioning reference signal configuration information, receiving assistance data based on the positioning reference signal configuration information, measuring one or more downlink positioning reference signals based at least in part on the positioning reference signal configuration information, and determining a location of the mobile device based at least on part on the measurements obtained from the one or more downlink positioning reference signals and the assistance data.

Systems and methods for support of on-demand positioning reference signals in a wireless network

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.
