Abstract: Embodiments of the present disclosure relate to UL-based and DL-based positioning in a wireless communication network. A method comprises: determining, by a first device, an estimation of a propagation delay for a first reference signal to be transmitted from a second device; in accordance with a determination that the estimation of the propagation delay exceeds a threshold delay, determining a target period within a symbol on which at least a part of the first reference signal is transmitted; and performing positioning measurements on the first reference signal within the target period. As such, the receiver is capable of applying an adaptive and adjustable window for receiving different positioning reference signals (PRSs) depending on various conditions and situations. In this way, the PRS measurement performance and the positioning accuracy can be greatly improved.

Abstract: Determining positioning of a UE in a network includes the UE transmitting mobility status information to a LMF. A wireless network broadcasts configuration parameters for a set of mobility indicators. A receiving UE evaluates the configuration parameters and derives mobility status information, which the UE reports to the LMF. The LMF then determines positioning frequency layer and positioning reference signal configurations on DL (PRS) and UL (SRS). The LMF then sends the positioning frequency layer and reference signal configurations for DL and/or UL and positioning measurement and reporting configurations to the UE, its serving gNB and configured neighbour gNBs. The UE and gNB(s) then perform positioning measurements according to the positioning reference signal configurations for DL and/or UL and according positioning measurement and reporting configurations and report the positioning measurements to the LMF to determine the UE's position in the wireless network.

Abstract: A method can include determining that a received signal traveled via a shortest path from a transmitting device to a receiving device of an orthogonal frequency-divisional multiplexing (OFDM) communication system, determining a phase rotation of the received signal, and determining a time of arrival based on the determined phase rotation.

Abstract: Systems, methods, apparatuses, and computer program products for improved uplink (UL) positioning are provided. One method may include transmitting, by a location management entity, a request for spectrum sensing information to one or more serving network nodes and neighbor network nodes (650), receiving the spectrum sensing information from the one or more serving network nodes and neighboring network nodes (655), calculating sounding reference signal (SRS) resources for the one or more serving network nodes using the received spectrum sensing information (665), indicating, to the one or more serving network nodes, a list of sounding reference signal (SRS) configurations obtained based on the calculated sounding reference signal (SRS) resources (670), and receiving, from the one or more serving network nodes, an indication of a selected one of the sounding reference signal (SRS) configurations (675).

Abstract: To position a terminal device, at least one transmission-reception point, or corresponding apparatus, the terminal device and a network entity exchange information. A transmission-reception point receives from the network entity a first signal comprising at least one parameter setting for positioning reference signal transmissions. The terminal device receives from the network entity a second signal comprising at least the parameter setting. The network entity receives from the transmission-reception point a first report indicating at least an occurrence time of a successful transmission of a positioning reference signal and from the terminal device a measurement report comprising information on at least the positioning reference signal. The network entity determines a position of the terminal device based on at least the first report and the measurement report.

Abstract: According to embodiments of the present disclosure, a PRS transmission timing scheme for sidelink assisted positioning is proposed. According to embodiments of the present disclosure, the supporting terminal device measures a receiving-transmitting (Rx-Tx) time difference between receiving the downlink PRS (DL) and transmitting the sidelink (SL) PRS. The supporting terminal device transmits an indication of the RX-TX time difference to the location management device in order to reduce the impact of low synchronization issue on positioning performance as well as the use of wideband PRS for higher measurement accuracy. In this way, the positioning performance of sidelink assisted positioning has been improved.

Abstract: 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.

Abstract: A first apparatus may be configured, over a serving cell, to indicate to a second apparatus controlling the operation of the serving cell, a suitability of a non-serving cell for one or more inter-cell purposes. For example, the first apparatus may receive from the second apparatus Layer 3, L3, measurement configuration information including a criterion for one or more first inter-cell purposes. When the first apparatus detects, based on performed L3 measurements of one or more reference signals in one or more non-serving cells that the criterion is met for L3 measurements of a first reference signal in a first non-serving cell, the first apparatus transmits a measurement report indicating that the first non-serving cell is a suitable cell for performing L1 measurements by the first apparatus for one or more second inter-cell purposes.
