Associating sensing information with a user
Certain example embodiments provide systems, methods, apparatuses, and computer program products for associating sensing information with a user (e.g., a cellular user) by, for example, determining information from both a sensing node and a communication node, then associating the a sensed object and the communication node based on the information. Additionally, or alternatively, some embodiments provide systems, methods, apparatuses, and computer program products for radar and sensing-based positioning.

transmit, to the user equipment, a message, wherein the message is associated with causing the user equipment to transmit a signal;
receive the signal from the user equipment;
identify the user equipment as a sensed object based on the signal by associating an identifier of the user equipment with a sensing identifier of the sensed object; and
transmit location information to the network node, wherein the location information identifies a location of the user equipment.
2. The apparatus according to claim 1 , wherein the at least one memory and the computer program code are configured to, with the at least one processor, further cause the apparatus at least to:
determine a location of various objects or users in a cell based on performing sensing prior to transmitting the message.
