Definitions
- GNSS carrier phase positioning has been used very successfully for centimeter-level positioning but is limited to outdoor applications.
- NR carrier phase positioning has the potential for significant performance improvements for indoor and outdoor deployments in comparison with the existing NR positioning methods, as well as shorter latency and lower UE power consumption in comparison with RTK-GNSS outdoors.
- the various positioning modes belong to three categories, where the term “User Equipment” or “UE” is interchangeable with “wireless communication device.”
- a first category may be regarded as UE assisted, where the UE performs measurements with or without assistance from the network and sends the measurements to a positioning node in the network.
- An example positioning node is an Enhanced Serving Mobile Location Center (E-SMLC). See 3GPP TS 23.271 for example details.
- E-SMLC Enhanced Serving Mobile Location Center
- Figure 16 illustrates another example embodiment of a device 12, where the device 12 includes radio frequency (RF) front-end circuitry 120, baseband processing circuitry 122, host processing circuitry 124, a user interface 126, and a power supply/battery 128.
- the baseband processing circuitry 122 comprises all or part of the processing circuitry 86 illustrated in Figure 13, with the host processing circuitry 124 executing one or more software applications that make use of sidelink communications, where such usage may be conditioned or controlled in dependence on the sidelink range.
- the determination of an improved sidelink range estimate based on the use of direct and synthetic estimates of sidelink range provides an improved basis for conditioning or controlling sidelink communications.
- the RF front-end circuitry 120 comprises all or part of the communication circuitry 80 illustrated in Figure 13, while details of the user interface 126 depend on the nature of the device 12.
- the user interface 126 includes a touchscreen and audio output.
- Sending the synthetic sidelink range estimate to the first wireless communication device comprises, for example, sending the synthetic sidelink range estimate in assistance information sent from the network node for the first wireless communication device.
- the assistance information directs the first wireless communication device to use the synthetic sidelink range estimate as the estimate of sidelink range to the second wireless communication device.
- the device In response to the request from the location server, the device will report sidelink range measurements as part of the NR-DL-TDOA-ProvideLocationlnformation IE as defined in 3GPP TS 37.355 V16.6.0.
- the device 12 may report sidelink range measurements associated with one other device 12 or multiple other devices 12 as part of the NR-DL-TDOA- ProvideLocationlnformation IE.
- the location server may combine the sidelink range measurements reported by the device with the RSTD measurements.
- a method of operation by a wireless communication device comprising: performing a sidelink ranging procedure with respect to another wireless communication device, the ranging procedure yielding a first range estimate for the distance between the wireless communication devices; send a request message towards a network node of a wireless communication network, requesting a second range estimate, the request message identifying the wireless communication devices; receiving the second range estimate from the network node or another network node of the wireless communication network, the second range estimate determined from estimated positions of the wireless communication devices; and determining a final range estimate in dependence on the first range estimate and the second range estimate.
- embodiment B 1 or B2 further comprising performing or initiating the performance of positioning procedures for the first and second wireless communication devices, the positioning procedures based network measurements, device measurements, or satellite positioning, or any combination thereof.
- a wireless communication device comprising: an antenna configured to send and receive wireless signals; radio front-end circuitry connected to the antenna and to processing circuitry, and configured to condition signals communicated between the antenna and the processing circuitry; the processing circuitry being configured to perform any of the steps of any of the Group A embodiments; an input interface connected to the processing circuitry and configured to allow input of information into the UE to be processed by the processing circuitry; an output interface connected to the processing circuitry and configured to output information from the UE that has been processed by the processing circuitry; and a battery connected to the processing circuitry and configured to supply power to the UE.

Abstract
Un dispositif de communication sans fil (12-1) utilise une estimation de distance de liaison latérale synthétique en tant que son estimation de la distance de liaison latérale jusqu'à un autre dispositif de communication sans fil (12-2), l'estimation synthétique provenant des emplacements des dispositifs et offrant une estimation plus fiable dans certaines conditions, par comparaison avec une estimation de distance de liaison latérale directe dérivée de mesures de signal de liaison latérale effectuées par un ou les deux dispositifs. Par exemple, il peut ne pas y avoir de trajets de propagation LoS entre les dispositifs. Dans un mode de réalisation, un appareil tel qu'un nœud de réseau d'un réseau de communication sans fil ou une unité de référence de positionnement envoie l'estimation synthétique à au moins l'un des dispositifs. L'envoi de l'estimation synthétique se produit, par exemple, en réponse à la réception d'une demande en provenance d'au moins l'un des dispositifs ou en fonction de la détermination que l'estimation synthétique est préférable. Dans un mode de réalisation, un ou les deux dispositifs décident que l'utilisation de l'estimation synthétique est préférable.
