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: A method for identifying potentially interfering devices is provided. The method may include receiving, by a first base station, an information element comprising information for identifying location of a first device with respect to the first base station, and sending a request to a second base station. The request may include location information on the basis of the received information element. The method may include receiving, in response to the request, an identifier of at least one further device, and transmitting the identifier of the at least one further device to the first device for interference measurements.

Abstract: An apparatus, method and computer program is described comprising: sampling a positioning reference signal received at a user device of a mobile communication system from a communication node of the mobile communication system, wherein the received positioning reference signal is a multipath signal having a line of sight component; processing the sampled received positioning reference signal with the positioning reference signal as transmitted by the communication node; identifying, based on said processing, signal paths from the communication node to the user device relative to an angle of departure of the positioning reference signal; and generating a model to estimate at least one of an orientation of the user device and a gain of the one or more identified signal paths of the multipath signal.

Abstract: An apparatus comprising circuitry configured to: receive a plurality of signal samples, wherein at least two of the signal samples are received on different carrier frequencies or over different durations; convert the plurality of signal samples to a common data format that stores as entries the samples, a stored entry corresponding to a sample measured with a carrier frequency, a time, and a receive antenna; generate entries of the common data format that are missing due to a sample not being measured with a carrier frequency, time, and receive antenna; wherein the entries of the common data format are ranked, wherein a higher ranking entry is considered more relevant than a relatively lower ranking entry; and generate at least one positioning measurement with a machine learning model, based on the entries of the common data format and the ranking of the entries of the common data format.
