Abstract: Various example embodiments relate to a solution for positioning of a low power device using sidelink peers. A target user device for a locally assisted positioning procedure may receive a trigger event to initiate positioning of the target user device, the trigger event originating from a location management function in relation to the locally assisted positioning procedure. The target user device may transmit at least one local positioning aid request to one or more anchor user devices for the locally assisted positioning procedure, the at least one local positioning aid request indicating a need for the locally assisted positioning procedure for the positioning of the target user device. Devices, methods, and computer programs are disclosed.

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.
