Various example embodiments relate to provision of a positioning time gap in a paging procedure. An apparatus may obtain positioning capability information of a device. The positioning capability information may comprise an indication of a first time period for determining a position of the device with first initial positioning data and an indication of a second time period for determining the position of the device with second initial positioning data. A positioning time gap may be determined based on the positioning capability information of the device. The apparatus may transmit a first signal, but refrain from transmitting a second signal for at least a duration of the positioning time gap from the first signal. Apparatuses, methods, and computer programs are disclosed.

Positioning time gap scheduling for non-terrestrial communication

Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for implicit indication of positioning related information. A first device selects a reference signal (RS) sequence from a plurality of available RS sequences. Based on the selected RS sequence, the first device generates a RS for positioning and then transmits the generated RS to a second device to indicate, with the selection of the reference signal sequence, at least part of side information related to the positioning.

Indication of positioning related information

The disclosure includes an apparatus, having: means for receiving, from a network entity, configuration information to indicate a window which is bandwidth-part free; and means for transmitting, to the network entity, a sounding reference signal in frequency hopping within the indicated window. The disclosure also includes a method which may include receive, from a network entity, configuration information to indicate a window which is bandwidth-part free. The method may also include transmitting, to the network entity, a sounding reference signal in frequency hopping within the indicated window.

Bandwidth part free sounding reference signal for positioning frequency hopping

An apparatus, for example a target UE, may be configured to: request at least one single difference carrier phase measurement of at least one positioning reference signal, wherein the at least one single difference carrier phase measurement is performed with at least one positioning reference unit; transmit an indication of a set of time-stamps for measurement of the at least one positioning reference signal; receive first measurement data for the at least one positioning reference signal, wherein the first measurement data comprises, at least, the at least one single difference carrier phase measurement measured with reference to the set of time-stamps; and determine a location estimation of the apparatus, comprising performing a double differential operation based, at least partially, on the first measurement data and second measurement data.

Enhancing positioning measurement

A wireless device drops sounding reference signal (SRS) transmissions, in SRS resources linked for bandwidth aggregation, that conflict in time with a transmission or a reception scheduled by downlink control information (DCI). A time period between a last symbol of the DCI and a starting symbol of the SRS transmissions is equal to, or greater than, a number of symbols plus a guard period of the bandwidth aggregation.

Collision timeline for bandwidth aggregation

Embodiments of the present disclosure relate to beam selection during downlink positioning. According to embodiments of the present disclosure, the terminal devices are grouped based on their characteristics and the anchor terminal device in the group determines the best transmitting beam of the neighbor network device. The non-anchor terminal device uses the assistance information of the best transmitting beam determined by the anchor terminal device. In this way, cost for the terminal device to receive and measure the PRS during downlink positioning has been reduced.

Beam selection during downlink positioning

A method including receiving, at a user equipment, one or more location related information, where the location related information comprises information based upon location related to one or more satellite; determining, by the user equipment, timing advance, where the determining is at least partially based upon the location related information; determining, by the user equipment, to perform a preconfigured uplink resource transmission; and performing, based at least partially upon the determined timing advance, the preconfigured uplink resource transmission.

UE location validation for PUR in LEO networks

A method for calibrating timing errors to improve positioning accuracy includes receiving, from a network element, calibration configuration information for communicating at least one positioning reference signal; communicating, during a positioning session and on the basis of the received calibration configuration information, a first positioning reference signal according to a first positioning reference signal pattern; and communicating, during the positioning session or during another positioning session and on the basis of the received calibration configuration information, a second positioning reference signal according to a second positioning reference signal pattern, wherein the second number of frequency resource elements is smaller than the first number of frequency resource elements and/or wherein the second number of time resource elements is greater than the first number of time resource elements.

Timing error correction in positioning of terminal device

Systems, methods, apparatuses, and computer program products for user equipment (UE)-based positioning non-line of sight (NLOS) error mitigation. For example, some embodiments described herein may provide for use of a blind-learning-type algorithm for channel bias distribution estimation for UE-based positioning. The UE may perform a calculation of a positioning of the UE using NLOS bias distribution received from a network node, as described elsewhere herein.

User equipment (UE)-based positioning non-line of sight (NLOS) error mitigation

Certain example embodiments provide systems, methods, apparatuses, and computer program products for associating sensing information with a user (e.g., a cellular user) by, for example, determining information from both a sensing node and a communication node, then associating the a sensed object and the communication node based on the information. Additionally, or alternatively, some embodiments provide systems, methods, apparatuses, and computer program products for radar and sensing-based positioning.

Associating sensing information with a user

To increase positioning accuracy, channel characteristics are determined taking into account receive filter response and transmit filter response. For example, upon receiving assistance data for positioning an apparatus, a transmit sequence is generated using the assistance data; and a combination of the transmit sequence is generated by combining the transmit sequence. Further, a receive filter response is determined, a transmit filter response is obtained, and a combined filter response is generated using the receive filter response and the transmit filter response. Reference signals received over a channel are measured by sampling them into a plurality of time-domain samples, and the channel is estimated from the plurality of time-domain samples using the combined filter response and the combination of the transmit sequence. Then, per channel characteristics, a value of the channel characteristics based on the channel estimated is determined.
