MULTI-SITE RANGE RATE MEASUREMENT COMPILATION IN A WIRELESS COMMUNICATION SYSTEM
A method for providing motion information of a UE in a wireless communication system. The method comprises initiating, in a first network node, of a first Doppler shift measurement concerning the UE. In the first network node, a transfer of requests for second Doppler shift measurement concerning the UE is initiated to second network nodes. Data representing the first Doppler shift measurement is obtained in the first network node. Data representing the second Doppler shift measurements is obtained in the first network node. An estimated motion, in more than one dimension, of the UE is determined in dependence of at least the obtained data representing the first Doppler shift measurement and the obtained data representing the second Doppler shift measurements. A method for assisting by the second network node, as well as network nodes performing the methods are also disclosed.
OBTAINING LOCATION INFORMATION
A system comprising a first apparatus, a second apparatus and a third apparatus, wherein the first apparatus is configured to provide, to a second apparatus, information regarding a number of antennas and/or an oversampling factor; the second apparatus is configured to transmit a plurality of beams in accordance with the information received from the first apparatus regarding the number of antennas and the oversampling factor; the third apparatus configured to receive a plurality of beamformed reference signals transmitted by the second apparatus, obtain measurement results for at least two of the plurality of beamformed reference signals, wherein the measurement results comprise one or more of: reference signal received power value, beam identifier, a value indicating uncertainty of the accuracy of the reference signal received power value; and transmit the measurement results to the second apparatus; and wherein the second apparatus is further configured to: process the received measurement results to obtain information regarding a position of the third apparatus and to transmit the obtained information regarding the position of the third apparatus to the first apparatus; and wherein the first apparatus is further configured to receive further measurement results from at least one further apparatus in addition to the second apparatus and to determine the location of the third apparatus based on the received measurement results and the received further measurement results.
Authentication of vehicle-to-vehicle communications
Systems, methods, and devices for authenticating vehicle-to-vehicle communication are disclosed. A method includes receiving sensor data from a first vehicle and receiving secondary sensor data from a second vehicle. The method includes extracting, based on the sensor data and the secondary sensor data, an authentication comprising one or more of: a proximity of the second vehicle to the first vehicle or a common object identified by the sensor data and the secondary sensor data. The method includes determining whether the authentication satisfies a trust threshold of the first vehicle.
POSITIONING METHOD, TERMINAL, AND NETWORK DEVICE
The present invention relates to the field of communications technologies, and provides a positioning method, a terminal, and a network device. The positioning method includes: obtaining positioning information, where the positioning information includes priority information related to a positioning signal, and/or measurement time information of a positioning signal; and determining the positioning signal based on the positioning information.
APPARATUS, METHODS, AND COMPUTER PROGRAMS
There is provided a method for an apparatus for a location service, the method comprising: receiving, from a network function, a location request to determine a location of a terminal, the location request comprising a first indication of a first area: determining whether the terminal is inside or outside of the first area; and sending, to the network function, a second indication of whether the terminal is inside or outside of the first area.
SYSTEMS AND METHODS FOR SUPPORTING A LOCATION UNCERTAINTY FOR A SCHEDULED LOCATION
The location of a user equipment (UE) is determined at a scheduled location time based on location measurements for the UE received from one or more other entities. The location measurements are obtained at a plurality of times based on the scheduled location time. An uncertainty of the location that indicates a difference between the location and an actual location of the UE at the scheduled location time is determined and the location and the uncertainty of the location are sent to a requesting entity. The uncertainty of the location is based on a location uncertainty and a time uncertainty relative to the scheduled location time, which are combined into a single location uncertainty.
DEVELOPING A FINGERPRINT MAP FOR DETERMINING AN INDOOR LOCATION OF A WIRELESS DEVICE
Techniques are described herein for developing a fingerprint map that may be used for 3D indoor localization. In one example, a network server may leverage a building footprint from an open source database with signal measurements taken by probing user devices from signal sources such as access point (AP) devices. The network server may use the signal measurements to remotely calculate corresponding 3D positions of the AP devices in a particular building. Further, the network server may use the building footprint and the calculated 3D positions of the AP devices as references for developing the fingerprint map for 3D indoor localization.
PRIORITY AND COLLISION FOR COLLIDING POSITIONING STATE INFORMATION (PSI) REPORTS
A user equipment (UE) generates a positioning state information (PSI) report to be transmitted in a lower layer channel, e.g., in the Physical or Medium Access Control channel, to a network entity to reduce latency. The PSI reports may be generated based on information from uplink (UL), downlink (DL) or UL and DL positioning measurements performed by the UE. When multiple PSI reports collide, e.g., to be transmitted simultaneously, or when a PSI report and a Channel State Information (CSI) report collide, prioritization of the reports is performed using priority rules based at least in part on positioning related content of the PSI reports. The PSI report or CSI report with the highest priority is transmitted to the network entity on the lower layer channel, and lower priority reports may be omitted. A network entity may receive and process the PSI report based on the priority based rules.
PARTIAL POSITIONING STATE INFORMATION (PSI) OMISSION FOR LOWER LAYER TRANSMISSION
A user equipment (UE) generates a positioning state information (PSI) report that is transmitted in a lower layer channel container, e.g., in the Physical channel or Medium Access Control channel, to a network entity to reduce latency. For example, the PSI report is generated based on a plurality of PSI report elements determined from uplink (UL), downlink (DL) or UL and DL positioning measurements. Each PSI report element includes information related to positioning measurements performed by the UE. The PSI report elements are ordered, e.g., from highest priority to lowest priority, according to priority based rules. If the size of the PSI report elements is larger than the lower layer channel container, one or more of the low priority PSI report elements are omitted from the PSI report. A network entity may receive and process the PSI report based on the same priority based rules.
Using in-home location awareness
Techniques for suggesting accessory devices controlled by an application executing on a mobile device are disclosed. A method includes measuring one or more sensor values using one or more sensors of a mobile device and the one or more sensor values are determined from one or more signals emitted by a first one or more accessory devices. An area of a physical space for the first one or more accessory devices can be determined based on the one or more sensor values. A second one or more accessory devices associated with the same area as the first one or more accessory devices can be suggested to a user.
