Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of antenna configuration for positioning. The method comprises identifying, at a first device, at least one second device hearable by the first device based on a monitoring of respective reference signals from the at least one second device; determining respective transmit power on at least two antenna panels allocated for the at least one second device based on a measurement associated with the respective reference signals; and transmitting, to the at least one second device, a message associated with a positioning of the first device by using the at least two antenna panels with the respective transmit power. In this way, the chance of successful PRACH for positioning reception at all identified involved gNBs may be optimized for maximized positioning accuracy at low latency and low UE power consumption.

Abstract: Embodiments of the present disclosure relate to methods, devices, apparatuses and computer readable storage media for multi-cell positioning. In example embodiments, a method is provided. The method includes transmitting, from a first network device, a first reference signal to a terminal device served by a second network device. The method further includes receiving a second reference signal from the second network device. The method further includes determining a first time difference between a time at which the first RS is transmitted and a time at which the second reference signal is received. In addition, the method includes transmitting information on the first time difference to a location server. As such, the location server can determine positioning information about the terminal device.

Abstract: A method for a base station includes sending a request for a report on beamforming capability to a target user equipment; receiving the report on the beamforming capability from the target user equipment; allocating at least one positioning reference signal resource for use by the target user equipment based on at least the capability information included in the report; determining a beam sweeping mle based on the at least one positioning reference signal resource allocated for the target user equipment; and sending the positioning reference signal resource allocation and the beam sweeping mle to the target user equipment. A corresponding method for a user equipment includes receiving a request for a report on beamforming capability from a serving base station; sending the report on the beamforming capability to the serving base station; receiving information relating to at least one positioning reference signal resource and a beam sweeping rule from the serving base station; and performing beam sweeping on uplink positioning reference signal transmissions using the received positioning reference signal resource allocation based on the beam sweeping rule.

Abstract: Methods and apparatus, including computer program products, are provided for switching between platforms. In some example embodiment, there may be provided a method, which may include receiving, by a user equipment, a notification indicative of a switch from a first platform to a second platform; calculating, by the user equipment, a timing advance for use with the second platform; and accessing, by the user equipment, the second platform after the switch to the second platform, the accessing based on at least the calculated timing advance. Related systems, methods, and articles of manufacture are also disclosed.

Abstract: Methods, apparatuses, and computer programs are provided for propagation delay compensation. A method for a UE includes receiving a configuration to provide a propagation delay notification for a propagation delay estimation; determining when the notification should be transmitted; transmitting the propagation delay notification; and determining a corresponding action based on the configuration of a relation between uplink reference signals and downlink reference signals. Methods are also provided for a radio node such as a base station.

Abstract: A TRP clusters multiple UEs into a group, configures selected ones of the UEs in the group to be head UEs, and configures UEs not selected as head UEs to be group UEs. The group UEs are configured to send signals or calculated information used for positioning of the group UEs to head UEs instead of to the TRP. The TRP receives calculated information that was calculated by the head UEs from the signals or calculated information used for positioning of the group UEs, and forwards the calculated information from the head user equipment toward a network node for position determination of the group UEs. The head UEs both transmit to and receive signals from the group UEs and use the signals to calculate the calculated information. The head UEs may also receive information calculated by the group UEs, which is also used to calculate the calculated information.

Abstract: Examples of the disclosure relate to position determination using one or more reflectors. In examples of the disclosure an apparatus can be configured to transmit information relating to one or more reflectors within a scattering environment to a network apparatus. The information relating to the one or more reflectors can be used by the network apparatus to enable signals reflected from the one or more reflectors to be used for a position determination.

Abstract: Improved techniques of UE local and network assisted compensation of the UE PCO impact on positioning reference signal include performing compensation of positioning measurement error by transmitting a reference signal to a proximate reference device. In some implementations, the reference signal is a wideband reference signal, and the compensation is over a wide band of frequencies. In some implementations, the positioning measurement error includes a PCO in-band variation (IBV). In such an implementation, the UE may associate a respective compensation over the wide band of frequencies with an antenna panel and/or an angle with respect to the proximate reference device (RD).
