[0220] In some cases, the rapid development of wireless communication technology and the growing demand for high-quality data transmission have driven the development of advanced communication systems. One promising technology is the integration of sensing and communication, which has the potential to revolutionize various industries, including automotive, healthcare, and smart cities.

[0221] In some embodiments, sensing is the use of radio frequency signals to obtain information about characteristics of the environment and / or objects in the environment (e.g., shape, size, direction, speed, position, distance or relative motion between objects, etc.).

[0222] In some embodiments, Integrated Sensing and Communication (ISAC) involves the simultaneous use of radio frequency (RF) signals for both sensing and communication. This integration can improve spectrum efficiency, reduce latency, and enhance reliability in a variety of applications. ISAC is particularly relevant in the context of mobile operators, user equipment (UE) vendors, automotive suppliers, and users, as it can significantly enhance the overall user experience, improve network efficiency, and enable new business opportunities.

[0223] In some embodiments, the integration of perception and communication enables the evolution of 3GPP networks from communication networks to integrated communication and sensing networks. It replicates the physical world through perception, exchanges information through communication, and connects the cyber and physical worlds, providing a key technical foundation for the fusion of the virtual and real worlds and expanding the scope of 3GPP technologies.

[0224] In some embodiments, the functional requirements and performance requirements of integrated perception and communication services with architectural impact are studied. In this study, perception applications, such as intruder detection applications (e.g., roads, railways, drone restricted areas, courtyards, and homes), monitoring applications (e.g., rainfall, tourism, floods, breathing, and movement), navigation assistance applications, real-time map generation applications, collision avoidance applications, etc. can be implemented using different perception methods through the 5G system to meet the required perception accuracy. For commercial, vehicle-to-everything (V2X), public safety, and emergency service use cases, targets with or without UEs (and their environments) can be supported on licensed or unlicensed spectrum. The study also determined service requirements in terms of perception configuration, 5G wireless perception services, disclosure, security, charging, etc.

[0225] In some embodiments, mobile operators can play a significant role in providing customers with integrated 5GS-based perception and communication services, including, for example, the management and control of 5G-based perception services. A 5G-Automotive Association (5GAA) technical report (5GAA_White-Paper_C-V2X-Use-Cases-Volume-II.pdf) illustrates the role operators can play in enhancing V2X-type services, particularly in infrastructure-assisted environmental perception, infrastructure-based teleoperation, high-definition map collection and sharing, and teleoperation support.

[0226] In some embodiments, other example use cases where 5GS is studied to provide communication-assisted awareness services are as follows:

[0227] Real-time environmental monitoring: Utilize wireless signals to reconstruct environmental maps, further improve positioning accuracy, and enable environmental applications. This includes a range of real-time monitoring applications, including dynamic 3D map-assisted driving, pedestrian flow statistics, intrusion detection, and traffic detection.

[0228] Autonomous vehicles or drones: Autonomous vehicles and drones share some common functional requirements. For example, they should support Detect and Avoid (DAA) to avoid obstacles. They should also be able to monitor path information, such as selecting routes and complying with traffic regulations.

[0229] Air pollution monitoring: The quality of the received wireless signal exhibits different attenuation characteristics with changes in air humidity, air particulate matter concentration, carrier frequency, etc., and can be used for weather or air quality detection.

[0230] Indoor healthcare and intrusion detection. It can realize respiratory rate estimation, respiratory depth estimation, apnea detection, vital sign monitoring of the elderly and indoor intrusion detection.

[0231] In some embodiments, referring to FIG. 1b , the ISAC system includes the following different roles:

[0232] Target or environment: The goal of the perceived information.

[0233] Transmitter: A device that transmits radio signals to a target object. It can be a UE or a gNB.

[0234] Receiver: A device that detects sensing information based on the reflection of radio signals from target objects. It can be a UE or a gNB.

[0235] Processor: A device that collects perception information and processes it to produce perception results. It can be a UE, gNB, core network entity, or application server.

[0236] Consumer: An authorized device that requests or subscribes to perception information and consumes the output computed from the perception information, such as a UE application, ISAC service application server, core network entity, or RAN node.

[0237] In some embodiments, the direct path between the transmitter and receiver may be blocked by obstacles such as buildings, trees, or terrain. Non-line-of-sight (NLOS) conditions can significantly affect wireless signal propagation, ultimately impacting the perceived Quality of Service (QoS), making it impossible to meet service requirements.

[0238] In some embodiments, a sensing entity may belong to a sensing area in which radio signals can reach a target or environment, thereby enabling sensing. However, the target to be sensed may be too far from the sensing entity (e.g., a transmitter or a receiver). Furthermore, due to the limited power or coverage of the sensing signal transmitted from the transmitter to the receiver, the sensing signal received by the receiver may be too weak to detect the target or environment.

[0239] In some embodiments, in NLOS conditions, or when the radio signal transmitted by the sensed entity cannot reach the sensed target, how to perform sensing is an issue that needs to be considered.
