[0057] To solve the above and / or other potential issues, embodiments of the present disclosure propose a solution of an ISAC architecture, and how to trigger sensing and collect the sensing data in this ISAC architecture.
[0058] Principles and implementations of the present disclosure will be described in detail below with reference to the figures.
[0059] FIG. 1 illustrates a schematic diagram of an example communication environment of an ISAC architecture 100 in which example embodiments of the present disclosure can be implemented. The communication environment of the ISAC architecture 100 shows a transportation scenario where sensing technologies are needed.
[0060] As illustrated, to support smart transportation and / or autonomous driving, one or more of network devices 120-1, 120-2 (which are collectively referred to as “network device 120” in some embodiments) , terminal devices 110-1, 110-2 (which are collectively referred to as “terminal device 110” in some embodiments) , and vehicles 104-1, 104-2 are equipped with sensing technologies, to sense the traffic conditions. Accurate sensing results are important to enable the safe and reliable control of the vehicles and to avoid accidents in the environment. One or more of the network devices 120-1, 120-2, terminal devices 110-1, 110-2, and vehicles 104-1, 104-2 may transmit signals for sensing certain objects in the environment. One or more of the network devices 120-1, 120-2, terminal devices 110-1, 110-2, and vehicles 104-1, 104-2 may collect measurement results of the sensing signals for use in the smart transportation and / or autonomous driving.
[0061] In some example embodiments, the network devices 120-1, 120-2 and the terminal devices 110-1, 110-2 are in a radio access network (RAN) . The terminal devices 110-1, 110-2 may communicate with the network device (s) 120-1 and / or the network device 120-2. The network devices 120-1, 120-2 may communicatively connect with a sensing management function (SEMF) device 130. The sensing management function device 130 may be for example implemented at an Operation Administration and Maintenance (OAM) device or an Access and Mobility Management Function (AMF) node.
[0062] It is to be noted that the OAM device or the AMF node is just one option as the SEMF device 130. In another option, the SEMF device 130 may be implemented as a node or device with a new function. In the following embodiments, OAM is indicative while SEMF can replace OAM as another option in the cases, although SEMF is not indicative in the embodiments.
[0063] The sensing management function device 130 may be connected to a sensing function (SF) device 140 in a core network (CN) 106. The CN 106 may further connect with one or more third-party applications 108. The third-party applications 108 may include one or more applications which support the smart transportation and / or autonomous driving, such as the map service provider, the Intelligent Transportation System (ITS) management platform, and the like. In some example embodiments, the vehicles 104-1, 104-2 may comprise communication devices which communicatively connect to the network devices 120-1, 120-2 or directly communicate with the third-party applications 108.
[0064] In the sensing scenario of smart transportation, the purposes of the sensing may include, but are not limited to, dynamic map (large area) for automatic driving, assisted driving, and road management based on the dynamic map; vehicle trajectory tracking; illegal driving (e.g. occupying the emergency lane, speeding) .
[0065] In addition to the smart transportation, there are many other sensing scenarios, such as unmanned aerial vehicle and indoor health. In the sensing scenario of unmanned aerial vehicle, the purposes of the sensing may include, but are not limited to, dynamic map (large area) such as automatic driving, assisted driving, route management based on a dynamic map; UAV trajectory tracking; space intrusion, route correction (such as UAV driving out of the air route, speeding, entering the no-fly zone) ; dynamic map (UE centered) : autonomous flying, assisted flying, and the like. In the sensing scenario of indoor health, the purposes of the sensing may include, but are not limited to, abnormal behavior detection (e.g., fall, sedentary, abnormal posture) ; detection of body indicators (e.g. respiration, heartbeat) ; smart control (control of the home based on human position and behavior, such as turning on lights) .
[0066] As shown in FIG. 1, the network device 120 may communicate with the sensing function device 140 via the sensing management function device 130, and may perform sensing service (s) or inform other devices to perform sensing service (s) . In some example embodiments, the network device 120 may obtain a sensing result, for example, based on the measurement result (s) of sensing signal (s) and provide it to the sensing management function device 130. In some alternative example embodiments, the network device 120 may receive the sensing result from a sensing receiver, e.g., another network device or a terminal device, and provide it to the sensing management function device 130.
[0067] The sensing management function device 130 may provide the sensing result to the sensing function device 140. The sensing result may be used for various purposes depending on the actual use cases. For example, in the use cases of smart transportation and / or autonomous driving, the sensing result may be used to provide driving warning or assistant driving information to the vehicles.
[0068] The sensing management function device 130 may be any suitable types of devices which can transmit a sensing request from the sensing function device 140 and provide the sensing result to the sensing function device 140. In some examples, the sensing management function device 130 may include or be implemented as a CN function or entity in the CN or an OAM device. Although the term “sensing management function device” is used herein, it may be interchangeably used with any other terms.
[0069] The sensing function device 140 may be any suitable types of devices which can receive the sensing result. In some examples, the sensing function device 140 may include or be implemented as a CN function or entity in the CN or a network device in the RAN. Although the term “sensing function device” is used herein, it may be interchangeably used with any other terms.
[0070] The signal transmitted for sensing (sometimes referred to as “sensing signal” ) may include any suitable types of signals, including but not limited to, Synchronization Signal Block (SSB) , Channel-State-Information Reference Signal (CSI-RS) , Positioning Reference Signal (PRS) , DeModulation Reference Signal (DMRS) , Sounding Reference Signal (SRS) , communication signal such as Orthogonal Frequency Division Multiplexing (OFDM) signal, specific sensing signal (s) , or any other signal.
[0071] A measurement result of a sensing signal for sensing may include the final sensing result such as the target distance, speed, dynamic maps, Reference Signal Received Power (RSPR) , Reference Signal Received Quality (RSRQ) , channel information etc., intermediate results such as point cloud information based on the sensing measurement, preliminary results such as delay spread spectrum, Doppler spectrum and other information, and / or raw measurements of the signal such as the in-phase / quadrature (I / Q) stream, or the like. The type of the measurement result may be flexibly configured for different use cases.
[0072] A sensing result may include any desired information that can be derived from the measurement result (s) of the sensing signal (s) . As some examples, the sensing result may include a distance of a target, a size of the target, a velocity of the target, a position of the target, a moving direction of the target, a surrounding environment of the target, real-time map, or the like.
[0073] The communications in the communication environment of the ISAC architecture 100 may conform to any suitable standards including, but not limited to, Global System for Mobile Communications (GSM) , Long Term Evolution (LTE) , LTE-Evolution, LTE-Advanced (LTE-A) , New Radio (NR) , Wideband Code Division Multiple Access (WCDMA) , Code Division Multiple Access (CDMA) , GSM EDGE Radio Access Network (GERAN) , Machine Type Communication (MTC) and the like. The embodiments of the present disclosure may be performed according to any generation communication protocols either currently known or to be developed in the future. Examples of the communication protocols include, but not limited to, the first generation (1G) , the second generation (2G) , 2.5G, 2.75G, the third generation (3G) , the fourth generation (4G) , 4.5G, the fifth generation (5G) communication protocols, 5.5G, 5G-Advanced networks, or the sixth generation (6G) networks.
[0074] It is to be understood that the number of devices and their connections shown in FIG. 1 are only for the purpose of illustration without suggesting any limitation. The communication environment of the ISAC architecture 100 may include any suitable number of devices configured to implementing example embodiments of the present disclosure. Although not shown, it would be appreciated that one or more additional devices may be located in the cell, and one or more additional cells may be deployed in the communication environment. It is noted that although illustrated as a network device, the network device may be another device than a network device. Although illustrated as a terminal device, the terminal device may be other device than a terminal device, such as a positioning reference unit (PRU) .
[0075] There are generally two types of sensing modes defined based on Tx / Rx node of sensing signal, namely, monostatic and bi-static. These types of sensing modes include 6 specific modes, namely, Sensing Mode 1 which is a gNB mono-static sensing, Sensing Mode 2 which is gNB-to-UE bi-static sensing, Sensing Mode 3 which is gNB-to-gNB bi-static sensing, Sensing Mode 4 which is UE mono-static sensing, Sensing Mode 5 which is UE-to-gNB bi-static sensing, and Sensing Mode 6 which is UE-to-UE bi-static sensing.
[0076] FIG. 2 illustrates schematic diagrams of six example sensing modes in accordance with some example embodiments of the present disclosure. As shown in FIG. 2, in Sensing Mode 1, as indicated by 201, a sensing signal for sensing a target 230 is transmitted by a network device 210 and received or measured by the network device 210 itself. In Sensing Mode 2, as indicated by 202, a sensing signal for sensing the target 230 is transmitted by the network device 210 and received or measured by a terminal device 220. In Sensing Mode 3, as indicated by 203, a sensing signal for sensing the target 230 is transmitted by the network device 210 and received or measured by another network device 212.
[0077] In Sensing Mode 4, as indicated by 204, a sensing signal for sensing the target 230 is transmitted by the terminal device 220 and received or measured by the network device 210. In Sensing Mode 5, as indicated by 205, a sensing signal for sensing the target 230 is transmitted by the terminal device 220 and received or measured by the terminal device 220 itself. In Sensing Mode 6, as indicated by 206, a sensing signal for sensing the target 230 is transmitted by the terminal device 220 and received or measured by another terminal device 222.
[0078] It would be appreciated that the sensing modes illustrated in FIG. 2 are examples only and there may be many other sensing modes. It would be appreciated that more than one second communication device may be involved in a sensing service. It can be seen from the sensing modes in FIG. 2 that there may be various combinations of the devices which are to measure a sensing signal.
[0079] Reference is made to FIG. 3, which illustrates a signaling flow 300 of a sensing process in accordance with some embodiments of the present disclosure. For the purposes of discussion, the signaling flow 300 will be discussed with reference to FIG. 1, for example, the network device 120 and the sensing management function device 130, and the sensing function device 140 in the ISAC architecture 100.
[0080] In the signaling flow 300, the sensing function device 140 transmits (305) , to a sensing management function device 130, a sensing request (also referred to as “third sensing request” for purpose of discussion) which at least includes a set of service parameters of a sensing service to be performed, to trigger the sensing management function device 130 to transmit (315) a sensing request (also referred to as “first sensing request” for purpose of discussion) at least comprising the set of service parameters, to a network device 120 capable of performing the sensing service.
[0081] The sensing management function device 130, upon receiving (310) the third sensing request, transmits (315) the first sensing request to the network device 120.
[0082] The network device 120 receives (320) , from the sensing management function device 130, the first sensing request for the sensing service to be performed. Then, the network device 120 may determine sensing mode information for the sensing service based on the first sensing request. The sensing mode information indicates a sensing mode, a sensing transmitter, and / or a sensing receiver.
[0083] The network device 120 further transmits (330) a sensing response (also referred to as “first sensing response” for purpose of discussion) comprising a sensing result to the sensing management function device 130. The sensing result is obtained at least based on the sensing mode information. For example, the sensing result may be obtained by the network device 120 itself (for example in the case where the network device 120 acts as a sensing receiver) , or may be received from a separate sensing receiver, for example, a terminal device or another network device.
[0084] The sensing management function device 130, upon receiving (335) the first sensing response from the network device 120, transmits (340) , to the sensing function device 140, a sensing response (also referred to as “third sensing response” for purpose of discussion) at least including the sensing result.
[0085] Thus, the sensing function device 140 receives (345) , from the sensing management function device 130, the third sensing response including a sensing result obtained at least based on the first sensing request.
[0086] In some implementations, in the ISAC architecture 100, a sensing service is triggered by the sensing function (SF) device 140. The SF device 140 sends a sensing requirement to the sensing management function (SEMF) device 130. The SEMF device selects the network device (e.g., gNB) 120 for the sensing service. The gNB 120 selects a sensing mode, as well as a corresponding sensing transmitter or a sensing receiver, and configures, guides or coordinates them for sensing. The gNB 120 collects the sensing data and may calculate or process the raw data. The gNB 120 sends the initial processed sensing data to the SF device 140 via the SEMF device 130.
[0087] As such, the gNB 120 selected by the SEMF device 130 is responsible for the selection of the sensing mode, managing and / or performing sensing. Moreover, the path SF-SEMF-gNB is used for sensing trigger / coordination / data collection and processing.
[0088] Reference is made to FIG. 4, which illustrates a signaling flow 400 of another sensing process in accordance with some embodiments of the present disclosure. Similar to FIG. 3, for the purposes of discussion, the signaling flow 400 also involves the network device 120 and the sensing management function device 130, and the sensing function device 140 in the ISAC architecture 100 shown in FIG. 1. Comparing with the signaling flow 300, the signaling flow 400 involves a sensing receiver 401 and a sensing transmitter 402 to provide a whole picture of the sensing process.
[0089] In the signaling flow 400, the sensing function device 140 transmits (405) , to a sensing management function device 130, a sensing request (also referred to as “third sensing request” for purpose of discussion) which at least includes a set of service parameters of a sensing service to be performed, to trigger the sensing management function device 130 to transmit (315) a sensing request (also referred to as “first sensing request” for purpose of discussion) at least comprising the set of service parameters, to a network device 120 capable of performing the sensing service.
[0090] The sensing management function device 130 receives (410) the third sensing request, and may select, from a plurality of candidate network devices, a network device capable of performing the sensing service based on the set of service parameters. In some embodiments, the sensing management function device 130 may have the knowledge of at least one of location information or capability information of each candidate network device, and thus may select a network device, for example, the network device 120.
[0091] Then, the sensing management function device 130 transmits (415) the first sensing request to the network device 120. The first sensing request at least comprises a set of service parameters of the sensing service. The set of service parameters may include, for example, but not limited to, environment or target information in a location related to the sensing service, an area scope related to the sensing service, an altitude of the location, or an accuracy of the sensing service.
[0092] The network device 120 receives (420) , from the sensing management function device 130, the first sensing request for the sensing service to be performed.
[0093] In some embodiments, the network device 120 may determine that a monostatic sensing mode, for example, the Sensing Mode 1 shown in FIG. 2, is to be applied. In this case, the network device 120 may transmit a sensing signal associated with the sensing service, and obtain the sensing result of the sensing signal by itself. In embodiments of the present disclosure, the sensing result may further include, for example, but not limited to, environment or target information in a location related to a sensing signal associated with the sensing service, an area scope related to the sensing signal, an altitude of the location, an accuracy of the sensing signal, and / or the like.
[0094] Alternatively, another monostatic sensing mode, for example, the Sensing Mode 4 shown in FIG. 2, may be applied. In this case, the network device 120 may transmit (425) a second sensing request to the sensing transmitter, for example, the terminal device 110, to cause the sensing transmitter to transmit a sensing signal associated with the sensing service and may receive a second sensing response from the sensing receiver which is also the terminal device 110. The second sensing response may comprise the sensing result of the sensing signal obtained by the sensing receiver, which, in this case, is the terminal device 110.
[0095] In some alternative embodiments, the network device 120 may determine that a bi-static sensing mode is to be applied. In such embodiments, the network device 120 may act as a sensing transmitter, and another network device or a terminal device (e.g., the terminal device 110) may act as a sensing receiver. Alternatively, the network device 120 may act as a sensing receiver, and another network device or a terminal device (e.g., the terminal device 110) may act as a sensing transmitter. As a further alternative, another network device and a terminal device may act as the sensing transmitter and the sensing receiver, respectively.
[0096] For example, the network device 120 transmits (425) a second sensing request to the sensing transmitter 402, to cause the sensing transmitter 402 to transmit a sensing signal associated with the sensing service. In this case, the network device 120 acts as a sensing receiver, and may obtain the sensing result of the sensing signal.
[0097] In another example, the network device 120 transmits (425) a second sensing request to the sensing transmitter 402, e.g., another network device or a terminal device. The second sensing request may comprise at least one of: sensing mode information for the sensing service, a set of service parameters, or a sensing configuration. In some embodiments, the sensing configuration comprises a Radio Frequency (RF) frequency of the sensing signal, a power of the sensing signal, a waveform of sensing signal, and / or other information.
[0098] The sensing transmitter 402 receives (430) the second sensing request from the network device 120. Then the sensing transmitter 402 may determine whether the sensing service is allowed to be performed at the sensing transmitter 402. If yes, the sensing transmitter 402 may transmit, to the network device 120, a sensing acknowledgement indicating that the sensing transmitter confirms to transmit a sensing signal associated with the sensing service. Thus, the network device 120 may receive the sensing acknowledgement from the sensing transmitter 402, and thus will know that the sensing transmitter 402 confirms to transmit a sensing signal associated with the sensing service.
[0099] In a still further example, the sensing transmitter 402 may transmit (435) , to the sensing receiver 401, a fourth sensing request for the sensing service. The fourth sensing request may comprise at least one of: the sensing mode information for the sensing service, the set of service parameters, or the sensing configuration.
[0100] Aa an alternative to the case where the sensing transmitter 402 transmits the fourth sensing request, the network device 120 may transmit (440) a second sensing request to the sensing receiver 401, e.g., another network device or a terminal device, and may receive (465) , from the sensing receiver 401, a second sensing response comprising the sensing result of the sensing signal obtained by the sensing receiver 401.
[0101] In some implementations, the second sensing request may comprise at least one of:the sensing mode information, the set of service parameters, or a sensing configuration.
[0102] More details related to the above different sensing scenarios will be discussed with respect to FIGS. 5A-8.
[0103] The sensing receiver 401 receives (445) a sensing request, for example, the second sensing request from the network device 120 or the fourth sensing request from the sensing transmitter 402. The sensing request comprises at least one of: sensing mode information for the sensing service, a set of service parameters, or a sensing configuration. Thus, the sensing receiver 401 may have the knowledge about the sensing service to be performed.
[0104] To perform the sensing service, the sensing transmitter 402 transmits (450) a sensing signal associated with the sensing service based on the second sensing request.
[0105] As to the sensing receiver 401. it obtains (455) a sensing result of the sensing signal associated with the sensing service transmitted from the sensing transmitter 402, and transmits (460) , to the network device 120, a second sensing response comprising the sensing result.
[0106] The network device 120 receives (465) the second sensing response from the sensing receiver 401 and transmits (470) a sensing response (also referred to as “first sensing response” for purpose of discussion) comprising a sensing result to the sensing management function device 130. The sensing result is obtained at least based on the sensing mode information. For example, the sensing result may be obtained by the network device 120 itself (for example in the case where the network device 120 acts as a sensing receiver) , or may be received from a separate sensing receiver, for example, a terminal device or another network device.
[0107] The sensing management function device 130, upon receiving (475) the first sensing response from the network device 120, transmits (480) , to the sensing function device 140, a sensing response (also referred to as “third sensing response” for purpose of discussion) at least including the sensing result.
[0108] Thus, the sensing function device 140 receives (485) , from the sensing management function device 130, the third sensing response including a sensing result obtained at least based on the first sensing request.

The sensing request 522 may include, for example, the location, area scope and altitude parameters from the SF device 140.
[0120] To fulfill the received sensing request 522, the network device 120 selects the sensing mode with Monostatic sensing via a UE under its coverage. The condition can be the accuracy requirement, which can not be fulfilled by the gNB monostatic sensing.
[0121] The network device 120 sends the sensing request 523 to the selected UE, in this example, the terminal device 110.

The condition may be the accuracy requirement, which can not be fulfilled by the gNB monostatic sensing.
[0128] The network device 120 sends the sensing request 523 to the selected UE, in this example, the terminal device 110.
