A wireless device () is configured for radio access technology, RAT, dependent positioning in a wireless communication network (). The wireless device () receives, from a network node (), assistance data () that assists the wireless device () with RAT-dependent positioning, e.g., downlink Observed Time Difference of Arrival. The assistance data () may be based on device-specific information. The device-specific information may for example include a subscription associated with the wireless device (). The wireless device () may perform the RAT-dependent positioning based on assistance from the assistance data ().

Assistance data for RAT-dependent positioning

Methods and apparatuses provide a mechanism to account for timing errors of a wireless device () in positioning measurements. In one example, a wireless device () performs reference-signal transmissions or measurements and sends information to a network node () that is involved in positioning of the wireless device (). The information indicates associations of the reference-signal transmissions or measurements with respective timing groups of the wireless device (). Each timing group represents a related set of transmission or reception timing errors within the wireless device (). Based on the information, the network node () accounts for the different timing-group associations when performing positioning calculations that are based on the reference-signal transmissions or measurements performed by the wireless device ().

Methods and apparatuses to account for timing errors of a user equipment in positioning measurements

A method performed by a wireless device in an Industrial Internet of Things (I-IoT) environment includes determining an availability level of a network and/or an integrity level of a positioning service and/or system at the wireless device. Based on the availability level of the network and/or the integrity level of the positioning service and/or system at the wireless device, the wireless device performs at least one action associated with the positioning service and/or system.

Methods and systems to define integrity for industrial internet of things

A method performed by a target device to obtain positioning assistance data from a location server is provided. The target device and the location server are operating in a wireless communications network. The target device transmits a request to the location server. The request is a request for positioning assistance data and provides first logical position information. The target device obtains positioning assistance data from the location server. The positioning assistance data is based on the first logical position information. When being associated with a second logical position, the target device transmits a request to the location server. The request requests for positioning assistance data and provides second logical position information. The target device obtains positioning assistance data from the location server. The positioning assistance data is based on the second logical position information.

Obtaining and providing positioning assistance data

Embodiments described herein relate to methods and apparatus in networks, and particularly methods, Location Management Functions, base stations and wireless devices for configuring and sending uplink sounding reference signals (UL SRS). An example method performed by a Location Management Function (LMF) comprises receiving radio resource information relating to radio resources that can be applied for UL SRS by a wireless device; and providing a notification relating to triggering aperiodic uplink SRS to a base station serving the wireless device.

Signalling support for NR positioning with aperiodic SRS configurations

A method performed by a wireless device, UE, for configuring a semi-persistent scheduling, SPS is described. In accordance with the method, the UE may be configured to monitor a first search space of a physical downlink control channel for downlink control information, DCI, dedicated to the UE. The method may include receiving from the communication network SPS configuration data to configure a second search space to be monitored by the UE for DCI to activate or de-activate the SPS, the second search space being smaller than the first search space, and monitoring the second search space to detect the DCI to activate or de-activate the SPS. A corresponding method may be performed by a network node.

Activation and de-activation of semi-persistent scheduling

A method performed by a User Equipment (UE) for determining an integrity level of an estimated position of the UE in a radio communications network. The UE obtains information from a network node operating in the radio communications network. The information is about service levels of positioning assistance information provided in the radio communications network. The service levels are related to any one or more out of Integrity (I), Availability (A), and Continuity (C). The UE further obtains positioning assistance information from the network node. The positioning assistance information relates to the established service levels. The UE then determines a positioning strategy based on the information about the service levels. The UE estimating the position of the UE according to the determined positioning strategy, and based on the obtained positioning assistance information, and determines an integrity level of the estimated position of the UE.

User equipment, network node and methods in a radio communications network

Methods may be provided to operate a Radio Access Network RAN node of a wireless communication network. Information defining an operational environment in which a wireless device is operating may be obtained. Communication with the wireless device may be managed based on the information defining the operational environment in which the wireless device is operating. Related RAN nodes, computer programs, and computer program products are also discussed.

Methods of managing communication based on information defining an operational environment and related nodes

According to certain embodiments, a method by a wireless device includes receiving, from a network node, a first indication of a system information data and broadcast status associated with on-demand delivery of the system information data. The wireless device transmits a request for the system information data to the network node while the wireless device is in Radio Resource Control, RRC, Connected Mode. Based on the broadcast status, the wireless device receives the on-demand delivery of the system information data from the network node.

Methods and procedures for enhanced on-demand delivery of positioning assistance data

In an example arrangement, a base station () serving a wireless device () controls the activation time for transmission by the wireless device () of aperiodic or semipersistent Sounding Reference Signals (SRS), but accounts for an activation-time recommendation made by a location server () with which the serving base station () provides its timing information. The arrangement allows the location server (), which has a view of the overall timeline, to recommend an activation time while still leaving the serving base station () in control of the activation time, which the serving base station () shares with the location server (). In turn, the location server () uses the activation time to configure neighboring base stations (), for example, for coordinated reception of the SRS, for positioning the device () via Uplink Observed Time Difference of Arrival (UTDOA) determinations. Activation of the SRS provides, for example, increased SRS density as compared to any ongoing periodic SRS transmissions performed by the wireless device ().
