Methods, architectures, apparatuses, and systems for mobility support of sensing for tracking

A system implementing one or more network functions of a core network of a wireless network, wherein the system comprises one or more processors configured to:

• receive a sensing service request for tracking a target object and path information;
• identify, based on the path information, a plurality of sensing entities;
• assign one or more sensing entities of the plurality of sensing entities to a respective group of a plurality of groups of sensing entities, wherein each of the plurality of sensing entities is assigned to at least one of the plurality of groups of sensing entities, and wherein each group of the plurality of groups of sensing entities is associated with a sensing service area of a plurality of sensing service areas;
• cause each of the plurality of sensing entities to be configured for sensing operation;
• determine that the target object is in a first sensing service area of the plurality of sensing service areas based on the path information;
• based on determining that the target object is in the first sensing service area, cause each sensing entity of a first group of sensing entities of the plurality of groups of sensing entities that is associated with the first sensing service area to be activated for sensing operation;
• receive first sensing measurements from the first group of sensing entities;
• determine a first sensing result based on the first sensing measurements;
• determine that the target object moved to a second sensing service area of the plurality of sensing service areas, wherein the second sensing service area is different from the first sensing service area;
• based on determining that the target object moved to the second sensing service area, cause each sensing entity of a second group of sensing entities of the plurality of groups of sensing entities that is associated with the second sensing service area to be activated for sensing operation;
• receive second sensing measurements from the second group of sensing entities;
• and
• determine a second sensing result based on the second sensing measurements.

A method performed by a wireless transmit/receive unit (WTRU) in communication with a wireless network, the method comprising:

• receiving configuration information from the wireless network;
• associating the WTRU with a sensing service area based on the configuration information;
• entering the WTRU into a sensing state and configuring the WTRU for sensing based on the configuration information;
• after the WTRU enters the sensing state and is configured for sensing, receiving an activation command from the wireless network;
• performing a sensing operation with respect to a target object based on the activation command;
• determining a sensing result based on the sensing operation;
• and
• transmitting data indicating the sensing result to the wireless network.
