[0065] Principles of the present disclosure will now be described with reference to some embodiments. It is to be understood that these embodiments are described only for the purpose of illustration and help those skilled in the art to understand and implement the present disclosure, without suggesting any limitation as to the scope of the disclosure. The disclosure described herein may be implemented in various manners other than the ones described below.
[0066] In the following description and claims, unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skills in the art to which this disclosure belongs.
[0067] References in the present disclosure to “one embodiment, ” “an example embodiment, ” “an embodiment, ” “some embodiments, ” and the like indicate that the embodiment (s) described may include a particular feature, structure, or characteristic, but it is not necessary that every embodiment includes the particular feature, structure, or characteristic. Moreover, such phrases do not necessarily refer to the same embodiment (s) . Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to affect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described.
[0068] It shall be understood that although the terms “first” and “second” or the like may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For example, a first element could also be termed as a second element, and similarly, a second element could also be termed as a first element, without departing from the scope of embodiments. As used herein, the term “and / or” includes any and all combinations of one or more of the listed terms.
[0069] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments. As used herein, the singular forms “a” , “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” , “comprising” , “has” , “having” , “includes” and / or “including” , when used herein, specify the presence of stated features, elements, and / or components etc., but do not preclude the presence or addition of one or more other features, elements, components and / or combinations thereof.
[0070] As described above, the sensing reports generated by the sensing Rx nodes may have different levels. The selection of sensing report level or processing level relates to sensing computation capability and communication link quality of the sensing Rx nodes. Specifically, different computation capability of different sensing Rx nodes may result in different delays when the sensing Rx nodes process the measured sensing signals to the same level, and some sensing Rx nodes may even be unable to process the measured sensing signals to specific levels. On the other hand, different quality of communication links of different sensing Rx nodes may result in different delays in transmitting data at the same level, and some sensing Rx nodes may even fail to transmit data at a specific level to the sensing server. In order to ensure the effectiveness of the final sensing result, it is necessary to study the selection of different sensing report levels or processing levels at the sensing Rx nodes.
[0071] In view of the above, the present disclosure provides a solution that supports cooperative sensing. In this solution, a first node for receiving a sensing signal obtains, from a sensing server, a request or configuration associated with a sensing report level or sensing computation capability of the first node. In turn, the first node provides, to the sensing server based on the request or configuration, information associated with the sensing report level or the sensing computation capability of the first node. With this solution, the sensing server may determine a sensing Rx node based on information associated with a sensing report level or sensing computation capability of a candidate sensing node. Thus, sensing performance may be improved.
[0072] Aspects of the present disclosure are described in the context of a wireless communications system.
[0073] Fig. 1 illustrates an example of a wireless communications system 100 that supports cooperative sensing in accordance with aspects of the present disclosure. The wireless communications system 100 may include one at least one of network entities 102 (also referred to as network equipment (NE) ) , one or more terminal devices or UEs 104, a core network 106, and a packet data network 108. The wireless communications system 100 may support various radio access technologies. In some implementations, the wireless communications system 100 may be a 4G network, such as an LTE network or an LTE-advanced (LTE-A) network. In some other implementations, the wireless communications system 100 may be a 5G network, such as an NR network. In other implementations, the wireless communications system 100 may be a combination of a 4G network and a 5G network, or other suitable radio access technology including institute of electrical and electronics engineers (IEEE) 802.11 (Wi-Fi) , IEEE 802.16 (WiMAX) , IEEE 802.20. The wireless communications system 100 may support radio access technologies beyond 5G. Additionally, the wireless communications system 100 may support technologies, such as time division multiple access (TDMA) , frequency division multiple access (FDMA) , or code division multiple access (CDMA) , etc.
[0074] The network entities 102 may be dispersed throughout a geographic region to form the wireless communications system 100. One or more of the network entities 102 described herein may be or include or may be referred to as a network node, a base station (BS) , a network element, a radio access network (RAN) node, a base transceiver station, an access point, a NodeB, an eNodeB (eNB) , a next-generation NodeB (gNB) , or other suitable terminology. A network entity 102 and a UE 104 may communicate via a communication link 110, which may be a wireless or wired connection. For example, a network entity 102 and a UE 104 may perform wireless communication (e.g., receive signaling, transmit signaling) over a Uu interface. The network entities 102 may be collectively referred to as network entities 102 or individually referred to as a network entity 102. Hereinafter, some implementations of the present disclosure will be described by taking a base station as an example of the network entity 102. Thus, the network entity 102 may be used interchangeably with the base station 102.
[0075] A network entity 102 may provide a geographic coverage area 112 for which the network entity 102 may support services (e.g., voice, video, packet data, messaging, broadcast, etc. ) for one or more UEs 104 within the geographic coverage area 112. For example, a network entity 102 and a UE 104 may support wireless communication of signals related to services (e.g., voice, video, packet data, messaging, broadcast, etc. ) according to one or multiple radio access technologies. In some implementations, a network entity 102 may be moveable, for example, a satellite associated with a non-terrestrial network. In some implementations, different geographic coverage areas 112 associated with the same or different radio access technologies may overlap, but the different geographic coverage areas 112 may be associated with different network entities 102. Information and signals described herein may be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referenced throughout the description may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof.
[0076] The one or more UEs 104 may be dispersed throughout a geographic region of the wireless communications system 100. A UE 104 may include or may be referred to as a mobile device, a wireless device, a remote device, a remote unit, a handheld device, or a subscriber device, or some other suitable terminology. In some implementations, the UE 104 may be referred to as a unit, a station, a terminal, or a client, among other examples. Additionally, or alternatively, the UE 104 may be referred to as an internet-of-things (IoT) device, an internet-of-everything (IoE) device, or machine-type communication (MTC) device, among other examples. In some implementations, a UE 104 may be stationary in the wireless communications system 100. In some other implementations, a UE 104 may be mobile in the wireless communications system 100.
[0077] The one or more UEs 104 may be devices in different forms or having different capabilities. Some examples of UEs 104 are illustrated in Fig. 1. A UE 104 may be capable of communicating with various types of devices, such as the network entities 102, other UEs 104, or network equipment (e.g., the core network 106, the packet data network 108, a relay device, an integrated access and backhaul (IAB) node, or another network equipment) , as shown in Fig. 1. Additionally, or alternatively, a UE 104 may support communication with other network entities 102 or UEs 104, which may act as relays in the wireless communications system 100.
[0078] A UE 104 may also be able to support wireless communication directly with other UEs 104 over a communication link 114. For example, a UE 104 may support wireless communication directly with another UE 104 over a device-to-device (D2D) communication link. In some implementations, such as vehicle-to-vehicle (V2V) deployments, vehicle-to-everything (V2X) deployments, or cellular-V2X deployments, the communication link 114 may be referred to as a sidelink. For example, a UE 104 may support wireless communication directly with another UE 104 over a PC5 interface.
[0079] A network entity 102 may support communications with the core network 106, or with another network entity 102, or both. For example, a network entity 102 may interface with the core network 106 through one or more backhaul links 116 (e.g., via an S1, N2, N2, or another network interface) . The network entities 102 may communicate with each other over the backhaul links 116 (e.g., via an X2, Xn, or another network interface) . In some implementations, the network entities 102 may communicate with each other directly (e.g., between the network entities 102) . In some other implementations, the network entities 102 may communicate with each other or indirectly (e.g., via the core network 106) . In some implementations, one or more network entities 102 may include subcomponents, such as an access network entity, which may be an example of an access node controller (ANC) . An ANC may communicate with the one or more UEs 104 through one or more other access network transmission entities, which may be referred to as a radio heads, smart radio heads, or transmission-reception points (TRPs) .
[0080] In some implementations, a network entity 102 may be configured in a disaggregated architecture, which may be configured to utilize a protocol stack physically or logically distributed among two or more network entities 102, such as an integrated access backhaul (IAB) network, an open radio access network (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance) , or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN) ) . For example, a network entity 102 may include one or more of a central unit (CU) , a distributed unit (DU) , a radio unit (RU) , a RAN intelligent controller (RIC) (e.g., a near-real time RIC (Near-RT RIC) , a non-real time RIC (Non-RT RIC) ) , a service management and orchestration (SMO) system, or any combination thereof.
[0081] An RU may also be referred to as a radio head, a smart radio head, a remote radio head (RRH) , a remote radio unit (RRU) , or a transmission reception point (TRP) . One or more components of the network entities 102 in a disaggregated RAN architecture may be co-located, or one or more components of the network entities 102 may be located in distributed locations (e.g., separate physical locations) . In some implementations, one or more network entities 102 of a disaggregated RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU) , a virtual DU (VDU) , a virtual RU (VRU) ) .
[0082] Split of functionality between a CU, a DU, and an RU may be flexible and may support different functionalities depending upon which functions (e.g., network layer functions, protocol layer functions, baseband functions, radio frequency functions, and any combinations thereof) are performed at a CU, a DU, or an RU. For example, a functional split of a protocol stack may be employed between a CU and a DU such that the CU may support one or more layers of the protocol stack and the DU may support one or more different layers of the protocol stack. In some implementations, the CU may host upper protocol layer (e.g., a layer 3 (L3) , a layer 2 (L2) ) functionality and signaling (e.g., radio resource control (RRC) , service data adaption protocol (SDAP) , packet data convergence protocol (PDCP) ) . The CU may be connected to one or more DUs or RUs, and the one or more DUs or RUs may host lower protocol layers, such as a layer 1 (L1) (e.g., physical (PHY) layer) or an L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU.
[0083] Additionally, or alternatively, a functional split of the protocol stack may be employed between a DU and an RU such that the DU may support one or more layers of the protocol stack and the RU may support one or more different layers of the protocol stack. The DU may support one or multiple different cells (e.g., via one or more RUs) . In some implementations, a functional split between a CU and a DU, or between a DU and an RU may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU, a DU, or an RU, while other functions of the protocol layer are performed by a different one of the CU, the DU, or the RU) .
[0084] A CU may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU may be connected to one or more DUs via a midhaul communication link (e.g., F1, F1-c, F1-u) , and a DU may be connected to one or more RUs via a fronthaul communication link (e.g., open fronthaul (FH) interface) . In some implementations, a midhaul communication link or a fronthaul communication link may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities 102 that are in communication via such communication links.
[0085] The core network 106 may support user authentication, access authorization, tracking, connectivity, and other access, routing, or mobility functions. The core network 106 may be an evolved packet core (EPC) , or a 5G core (5GC) , which may include a control plane entity that manages access and mobility (e.g., a mobility management entity (MME) , an access and mobility management functions (AMF) ) and a user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW) , a packet data network (PDN) gateway (P-GW) , or a user plane function (UPF) ) . In some implementations, the control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management (e.g., data bearers, signal bearers, etc. ) for the one or more UEs 104 served by the one or more network entities 102 associated with the core network 106.
[0086] The core network 106 may communicate with the packet data network 108 over one or more backhaul links 116 (e.g., via an S1, N2, N2, or another network interface) . The packet data network 108 may include an application server 118. In some implementations, one or more UEs 104 may communicate with the application server 118. A UE 104 may establish a session (e.g., a protocol data unit (PDU) session, or the like) with the core network 106 via a network entity 102. The core network 106 may route traffic (e.g., control information, data, and the like) between the UE 104 and the application server 118 using the established session (e.g., the established PDU session) . The PDU session may be an example of a logical connection between the UE 104 and the core network 106 (e.g., one or more network functions of the core network 106) .
[0087] In the wireless communications system 100, the network entities 102 and the UEs 104 may use resources of the wireless communications system 100 (e.g., time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers) ) to perform various operations (e.g., wireless communications) . In some implementations, the network entities 102 and the UEs 104 may support different resource structures. For example, the network entities 102 and the UEs 104 may support different frame structures. In some implementations, such as in 4G, the network entities 102 and the UEs 104 may support a single frame structure. In some other implementations, such as in 5G and among other suitable radio access technologies, the network entities 102 and the UEs 104 may support various frame structures (i.e., multiple frame structures) . The network entities 102 and the UEs 104 may support various frame structures based on one or more numerologies.
[0088] One or more numerologies may be supported in the wireless communications system 100, and a numerology may include a subcarrier spacing and a cyclic prefix. A first numerology (e.g., μ=0) may be associated with a first subcarrier spacing (e.g., 15 kHz) and a normal cyclic prefix. In some implementations, the first numerology (e.g., μ=0) associated with the first subcarrier spacing (e.g., 15 kHz) may utilize one slot per subframe. A second numerology (e.g., μ=1) may be associated with a second subcarrier spacing (e.g., 30 kHz) and a normal cyclic prefix. A third numerology (e.g., μ=2) may be associated with a third subcarrier spacing (e.g., 60 kHz) and a normal cyclic prefix or an extended cyclic prefix. A fourth numerology (e.g., μ=3) may be associated with a fourth subcarrier spacing (e.g., 120 kHz) and a normal cyclic prefix. A fifth numerology (e.g., μ=4) may be associated with a fifth subcarrier spacing (e.g., 240 kHz) and a normal cyclic prefix.
[0089] A time interval of a resource (e.g., a communication resource) may be organized according to frames (also referred to as radio frames) . Each frame may have a duration, for example, a 10 millisecond (ms) duration. In some implementations, each frame may include multiple subframes. For example, each frame may include 10 subframes, and each subframe may have a duration, for example, a 1 ms duration. In some implementations, each frame may have the same duration. In some implementations, each subframe of a frame may have the same duration.
[0090] Additionally or alternatively, a time interval of a resource (e.g., a communication resource) may be organized according to slots. For example, a subframe may include a number (e.g., quantity) of slots. The number of slots in each subframe may also depend on the one or more numerologies supported in the wireless communications system 100. For instance, the first, second, third, fourth, and fifth numerologies (i.e., μ=0, μ=1, μ=2, μ=3, μ=4) associated with respective subcarrier spacings of 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz may utilize a single slot per subframe, two slots per subframe, four slots per subframe, eight slots per subframe, and 16 slots per subframe, respectively. Each slot may include a number (e.g., quantity) of symbols (e.g., OFDM symbols) . In some implementations, the number (e.g., quantity) of slots for a subframe may depend on a numerology. For a normal cyclic prefix, a slot may include 14 symbols. For an extended cyclic prefix (e.g., applicable for 60 kHz subcarrier spacing) , a slot may include 12 symbols. The relationship between the number of symbols per slot, the number of slots per subframe, and the number of slots per frame for a normal cyclic prefix and an extended cyclic prefix may depend on a numerology. It should be understood that reference to a first numerology (e.g., μ=0) associated with a first subcarrier spacing (e.g., 15 kHz) may be used interchangeably between subframes and slots.
[0091] In the wireless communications system 100, an electromagnetic (EM) spectrum may be split, based on frequency or wavelength, into various classes, frequency bands, frequency channels, etc. By way of example, the wireless communications system 100 may support one or multiple operating frequency bands, such as frequency range designations FR1 (410 MHz –7.125 GHz) , FR2 (24.25 GHz –52.6 GHz) , FR3 (7.125 GHz –24.25 GHz) , FR4 (52.6 GHz –114.25 GHz) , FR4a or FR4-1 (52.6 GHz –71 GHz) , and FR5 (114.25 GHz –300 GHz) . In some implementations, the network entities 102 and the UEs 104 may perform wireless communications over one or more of the operating frequency bands. In some implementations, FR1 may be used by the network entities 102 and the UEs 104, among other equipment or devices for cellular communications traffic (e.g., control information, data) . In some implementations, FR2 may be used by the network entities 102 and the UEs 104, among other equipment or devices for short-range, high data rate capabilities.
[0092] FR1 may be associated with one or multiple numerologies (e.g., at least three numerologies) . For example, FR1 may be associated with a first numerology (e.g., μ=0) , which includes 15 kHz subcarrier spacing; a second numerology (e.g., μ=1) , which includes 30 kHz subcarrier spacing; and a third numerology (e.g., μ=2) , which includes 60 kHz subcarrier spacing. FR2 may be associated with one or multiple numerologies (e.g., at least 2 numerologies) . For example, FR2 may be associated with a third numerology (e.g., μ=2) , which includes 60 kHz subcarrier spacing; and a fourth numerology (e.g., μ=3) , which includes 120 kHz subcarrier spacing.
[0093] Fig. 2 illustrates another example of a wireless communications system 200 that supports cooperative sensing in integrated sensing and communication (ISAC) system in accordance with aspects of the present disclosure. As shown in Fig. 2, the wireless communications system 200 may comprise a node 210-1 for receiving a sensing signal, a node 210-2 for receiving a sensing signal, a node 210-3 for receiving a sensing signal, a node 220 for transmitting a sensing signal and a sensing server 230. Hereinafter, the node 210-1, the node 210-2 and the node 210-3 may be collectively referred to as first nodes 210 for receiving a sensing signal or individually referred to as a first node 210 for receiving a sensing signal.
[0094] In some implementations, the first node 210 may be implemented as a sensing node for receiving a sensing signal. In such implementations, the first node 210 may be referred to as a sensing receiving (Rx) node 210. For example, the first node 210 may be implemented as the base station 102 or the UE 104 in Fig. 1, or a TRP which is not shown in Fig. 1.
[0095] In some implementations, the node 220 may be implemented as a sensing node for transmitting a sensing signal. In such implementations, the node 220 may be referred to as a sensing transmitting (Tx) node 220. For example, the node 220 may be implemented as the base station 102 or the UE 104 in Fig. 1, or a TRP which is not shown in Fig. 1.
[0096] In some implementations, the sensing server 230 may be implemented as one of the following: the base station 102 or the UE 104 in Fig. 1, or a node in the core network 106. For example, the sensing server 230 may be implemented as a sensing function (SF) , a location management function (LMF) , an AMF in the core network 106.
[0097] In some implementations, the first nodes 210, the node 220 and the sensing server 230 may support cooperative sensing. In such implementations, each of the first nodes 210 may receive and measure a sensing signal from the node 220. Further, each of the first nodes 210 may process the measured sensing signal to generate a sensing report and transmit the sensing report to the sensing server 230. The sensing server 230 may determine a sensing result based on the sensing reports received from the first nodes 210. In the present disclosure, a sensing report is also referred to as a sensing measurement report or measurement report.
[0098] Alternatively, in some implementations which are not shown, multiple sensing Tx nodes and one sensing Rx node or multiple sensing Tx node and multiple sensing Rx nodes may support cooperative sensing. The scope of the present disclosure is not limited in this regard.
[0099] Fig. 3 illustrates a signaling diagram illustrating an example process 300 that supports cooperative sensing in accordance with aspects of the present disclosure. The process 300 may involve the first node 210 and the sensing server 230 in Fig. 2. For the purpose of discussion, the process 300 will be described with reference to Fig. 2.
[0100] As shown in Fig. 3, the sensing server 230 provides 310, to the first node 210 for receiving a sensing signal, a request or configuration associated with a sensing report level or sensing computation capability of the first node 210.
[0101] In turn, the first node 210 provides 320, to the sensing server 230 based on the request or configuration, information associated with the sensing report level or the sensing computation capability of the first node.
[0102] With the process 300, the sensing server 230 may determine or select a sensing Rx node based on information associated with a sensing report level or sensing computation capability of a candidate sensing node. Thus, sensing performance may be improved.
[0103] In some implementations, the request associated with the sensing report level or sensing computation capability of the first node 210 may comprise a request for the sensing computation capability, and the information associated with the sensing report level or sensing computation capability of the first node 210 may comprise the sensing computation capability.
[0104] In some implementations, the first node 210 may obtain the request for the sensing computation capability after the first node 210 registers in the core network 106, or after the first node 210 provides sensing capability of the first node 210 to the sensing server 230.
[0105] Alternatively, in some implementations, the request associated with the sensing report level or sensing computation capability of the first node 210 may comprise a request for computation capability of the first node 210 available for a sensing service, and the information associated with the sensing report level or sensing computation capability of the first node 210 may comprise the computation capability of the first node 210 available for the sensing service. The computation capability of the first node 210 available for a sensing service is also referred to as remaining computation capability of the first node 210.
[0106] In some implementations, the sensing report level may comprise one of the following: a sensing result, sensing intermediate data, sensing preliminary data, or sensing raw data.
[0107] In some implementations, the sensing result may comprise a distance and speed of a sensing target, such as vehicle inspection information, smart intersections, and dynamic maps.
[0108] In some implementations, the sensing intermediate data may comprise point cloud information generated by sensing measurement.
[0109] In some implementations, the sensing preliminary data may comprise at least one of the following: delay spread spectrum, Doppler spectrum, micro-Doppler spectrum, angle spectrum, or signal strength spectrum. The above spectrum information may contain information on multiple paths or multiple motion modes, and each path or each motion mode can be reflected by an independent spectrum line or parameter.
[0110] In some implementations, the sensing raw data may comprise at least one of the following: received signal or original channel information (such as the complex result, amplitude and / or phase, I / Q path and related operation results of the received signal or channel) .
[0111] In some implementations, the sensing report level may be associated with or mapped to a processing level of the first node 210 for the sensing signal. For example, the sensing report level may be the same as the processing level of the first node 210.
[0112] In some implementations, the sensing computation capability of the first node 210 may indicate or be associated with the sensing report level.
[0113] In some implementations, the sensing computation capability of the first node 210 may be associated with the processing level of the first node 210. For example, the sensing computation capability of the first node 210 may be the same as the processing level of the first node 210.
[0114] In some implementations, the term “sensing report level” may be used interchangeably with the term “sensing computation capability” or “processing level” .
[0115] In some implementations, the configuration associated with the sensing report level or sensing computation capability of the first node 210 may comprise a period for providing the information associated with the sensing report level or the sensing computation capability of the first node 210. In such implementations, the sensing server 230 may not provide, to the first node 210, the request for the sensing report level or sensing computation capability of the first node 210 available for the sensing service. The first node 210 may provide, to the sensing server 230, initial sensing computation capability of the first node 210 during the first node 210 registers in the core network 106. Then, the first node 210 may provide, to the sensing server 230, computation capability of the first node 210 available for the sensing service based on the period. For example, the initial sensing computation capability of the first node 210 may be the total sensing computation capability of the first node 210.
[0116] Fig. 4 illustrates a signaling diagram illustrating an example process 400 that supports cooperative sensing in accordance with aspects of the present disclosure. The process 400 may be considered as an example implementation of the process 300. The process 400 may involve the first node 210 and the sensing server 230 in Fig. 2. For the purpose of discussion, the process 400 will be described with reference to Fig. 2.
[0117] Generally, in the process 400, the first node 210 may act as a candidate sensing Rx node.
[0118] As shown in Fig. 4, the sensing server 230 provides 410, to the first node 210, a request for a sensing service. The request for the sensing service may comprise the configuration associated with a sensing report level or sensing computation capability of the first node 210. The configuration may comprise the sensing report level or the processing level.
[0119] Upon receiving the request for the sensing service, the first node 210 provides 420 a response to the sensing server 230.
[0120] In some implementations, if the first node 210 cannot support the sensing report level, the first node 210 may include a first indication associated with a rejection reason in the response. The first indication indicates that the sensing service is rejected.
[0121] In some implementations, the response may further comprise a further sensing report level supported by the first node 210.
[0122] On the other hand, if the first node 210 supports the sensing report level, the first node 210 may include a second indication in the response. The second indication indicates that the sensing service is accepted.
[0123] Upon receiving the response including the second indication, the sensing server 230 may select or determine the first node 210 as a sensing Rx node.
[0124] Different with communication resources which are controlled by the base station 102, computation resources may be mainly controlled by a sensing node itself. Considering computation resources of a sensing Rx node may be shared by multiple services, it needs to study how to determine usage of computation resources at a sensing Rx node. This will be described with reference to Fig. 5.
[0125] Fig. 5 illustrates a signaling diagram illustrating an example process 500 that supports cooperative sensing in accordance with aspects of the present disclosure. The process 500 may be considered as an example implementation of the process 300. The process 500 may involve the first node 210 and the sensing server 230 in Fig. 2. For the purpose of discussion, the process 500 will be described with reference to Fig. 2.
[0126] Generally, in the process 500, the first node 210 may act as a sensing Rx node selected by the sensing server 230.
[0127] As shown in Fig. 5, the sensing server 230 provides 510, to the first node 210, the configuration associated with the sensing report level or sensing computation capability of the first node 210. The configuration may comprise assistance data for a sensing service. The assistance data may comprise at least one of the following:
[0128] ● a third indication indicating the sensing service is urgent,
[0129] ● a priority of the sensing service,
[0130] ● importance of the sensing service, or
[0131] ● reserved time of computation resources suggested by the sensing server 230 for the sensing service.
[0132] In some implementations, the sensing server 230 may provide a request for a sensing service to the first node 210. The request for the sensing service may comprise the configuration associated with the sensing report level or the sensing computation capability. The configuration may comprise the assistance data for the sensing service.
[0133] Alternatively, in some implementations, the sensing server 230 may provide a sensing configuration to the first node 210. The sensing configuration may comprise the configuration associated with the sensing report level or the sensing computation capability. The configuration may comprise the assistance data for the sensing service.
[0134] Upon receiving the assistance data, the first node 210 determines 520 usage of computation resources of the first node 210 based on the assistance data.
[0135] In some implementations, if the assistance data comprises the third indication indicating the sensing service is urgent, the first node 210 may prioritize the sensing service based on the first indication or reject the sensing service if current service is also urgent.
[0136] In some implementations, if the assistance data comprises the priority of the sensing service or the importance of the sensing service, the first node 210 may determine whether to reject or accept the sensing service based on the priority or the importance of the sensing service. If the first node 210 determines to reject the sensing service, the first node 210 may include a rejection reason in the information associated with the sensing report level or the sensing computation capability of the first node 210. Then, the first node 210 may provide the information to the sensing server 230.
[0137] In some implementations, if the assistance data comprises the reserved time of computation resources suggested by the sensing server 230 for the sensing service, the first node 210 may avoid accepting other services than the sensing service during the reserved time.
[0138] In turn, the first node 210 provides 530 a sensing report associated with the sensing report level or the sensing computation capability of the first node 210.
[0139] In some implementations, the sensing report level or processing level needs to be updated. On the one hand, the first node 210 may dynamically schedule its computation resources based on priority or importance of the sensing service, which may result in the current computation resources for sensing not being able to support the configured sensing report level or processing level. On the other hand, dynamic communication links between the first node 210 and the sensing server 230 may also lead to failure of sensing report transmission in the configured sensing report level. To guarantee the sensing performance, the sensing report level or processing level needs to be updated to fit the dynamic sensing computation resources and the dynamic communication links. This will be described with reference to Figs. 6 and 7.
[0140] Fig. 6 illustrates a signaling diagram illustrating an example process 600 that supports cooperative sensing in accordance with aspects of the present disclosure. The process 600 may be considered as an example implementation of the process 300. The process 600 may involve the first node 210 and the sensing server 230 in Fig. 2. For the purpose of discussion, the process 600 will be described with reference to Fig. 2.
[0141] As shown in Fig. 6, the sensing server 230 provides 610, to the first node 210 for receiving a sensing signal, the configuration associated with the sensing report level or sensing computation capability of the first node 210.
[0142] In some implementations, the configuration associated with the sensing report level or the sensing computation capability of the first node 210 may comprise a fourth indication. The fourth indication indicates that the first node 210 is allowed to report a fifth indication to the sensing server 230.
[0143] In some implementations, the configuration may comprise at least one trigger condition for reporting the fifth indication to the sensing server 230.
[0144] In some implementations, the at least one trigger condition may comprise at least one of the following: sensing computation resources of the first node 210 being insufficient to support the sensing report level within a delay budget; or change of the sensing computation resources of the first node 210 being greater than a threshold.
[0145] The first node 210 determines 620 whether to transmit the fifth indication based on the configuration.
[0146] In some implementations, if the sensing computation resources changes, the first node 210 may include the fifth indication in the information associated with the sensing report level or the sensing computation capability and provide 630 the information to the sensing server 230. The fifth indication may indicate the sensing computation resources changes. Alternatively or additionally, the fifth indication may indicate the sensing report level supported by the first node 210.
[0147] In some implementations, if the at least one trigger condition is satisfied, the first node 210 may include the fifth indication in the information associated with the sensing report level or the sensing computation capability and provide 630 the information to the sensing server 230. The fifth indication may indicate the at least one trigger condition is satisfied. Alternatively or additionally, the fifth indication may indicate the sensing report level supported by the first node 210. Alternatively or additionally, the fifth indication may indicate the sensing computation resources changes.
[0148] Upon receiving the fifth indication, the sensing server 230 provides 640 an updated sensing report level to the first node 210.
[0149] In some implementations, the first node 210 may update the sensing report level autonomously based on the configuration. This will be described with reference to Fig. 7.
[0150] Fig. 7 illustrates a signaling diagram illustrating an example process 700 that supports cooperative sensing in accordance with aspects of the present disclosure. The process 700 may be considered as an example implementation of the process 300. The process 700 may involve the first node 210 and the sensing server 230 in Fig. 2. For the purpose of discussion, the process 700 will be described with reference to Fig. 2.
[0151] As shown in Fig. 7, the sensing server 230 provides 710, to the first node 210 for receiving a sensing signal, the configuration associated with the sensing report level or sensing computation capability of the first node 210.
[0152] In some implementations, the configuration may comprise a sixth indication. The sixth indication indicates that the first node 210 is allowed to change the sensing report level autonomously.
[0153] Alternatively or additionally, in some implementations, the configuration may comprise at least one threshold for changing the sensing report level autonomously.
[0154] Alternatively or additionally, in some implementations, the configuration may comprise at least one of the following:
[0155] ● mapping between the sensing report level and sensing computation resources,
[0156] ● mapping between the sensing report level and quality of communication link between the first node 210 and the sensing server 230,
[0157] ● mapping between the sensing report level and a combination of the sensing computation resources and the quality of communication link.
[0158] Upon receiving the configuration, the first node 210 determines 720 the sensing report level based on the configuration. For example, the first node 210 may determine an updated sensing report level autonomously based on the configuration.
[0159] In turn, the first node 210 provides 730 a sensing report associated with the sensing report level or the sensing computation capability of the first node 210.
[0160] In some implementations, besides sensing computation capability, there are other factors which may influence the selection of sensing Rx nodes, e.g., a distance between a candidate sensing Rx node and a sensing target. For some sensing service, e.g., target tracking, the closer of a sensing Rx node means the better sensing performance can be obtained. Thus, signals in the nodes near to the sensing target can provide more meaningful results than others, and it is beneficial to configure the sensing report level of the ‘near-target’ Rx nodes as sensing raw data to provide more data from ‘high-quality’ Rx nodes. To obtain the better sensing performance, the sensing report level or processing level configuration needs to consider other node related information for a sensing service.
[0161] In some implementations, the sensing server 230 may obtain, from the first node 210, information related to the first node 210. In turn, the sensing server 230 may determine the sensing report level based on the information related to the first node 210.
[0162] In some implementations, the information related to the first node 210 may comprise a position of the first node 210.
[0163] In some implementations, the sensing server 230 may provide, to the first node 210, a request for the information related to the first node 210.
[0164] In some implementations, the sensing server 230 may indicate, in the request, which node related information is needed.
[0165] Upon receiving the request, the first node 210 may provide, to the sensing server 230, the information related to the first node 210.
[0166] Upon receiving the information related to the first node 210, the sensing server 230 may determine the sensing report level or sensing computation capability of the first node 210 based on the information related to the first node 210.
[0167] In turn, the sensing server 230 provides the determined sensing report level or sensing computation capability to the first node 210.
[0168] As described above, in some implementations, the sensing server 230 may be implemented as a node in the core network 106, such as SF, LMF, or AMF. In such implementations, the base station 102 may request sensing computation capabilities from candidate sensing Rx nodes, and transfer the sensing computation capabilities to the node in the core network 106. This will be described with reference to Fig. 8.
[0169] Fig. 8 illustrates a signaling diagram illustrating an example process 800 that supports cooperative sensing in accordance with aspects of the present disclosure. The process 800 may involve the first node 210 in Fig. 2 as well as the base station 102 and a node 240 in the core network 106. For the purpose of discussion, the process 800 will be described with reference to Figs. 1 and 2.
[0170] As shown in Fig. 8, the base station 102 provides 810, to the first node 210 for receiving a sensing signal, a request or configuration associated with a sensing report level or sensing computation capability of the first node 210.
[0171] In turn, the first node 210 provides 820, to the base station 102 based on the request or configuration, information associated with the sensing report level or the sensing computation capability of the first node.
[0172] Then, the base station 102 transmits, to the node 240 in the core network 106, the information associated with the sensing report level or the sensing computation capability of the first node 210.
[0173] With the process 800, the node 240 in the core network 106 may determine or select a sensing Rx node based on information associated with a sensing report level or sensing computation capability of a candidate sensing node. Thus, sensing performance may be improved.
[0174] In some implementations, the sensing report level may comprise one of the following: a sensing result, sensing intermediate data, sensing preliminary data, or sensing raw data.
[0175] In some implementations, the configuration associated with the sensing report level or sensing computation capability of the first node 210 may comprise a period for providing the information associated with the sensing report level or the sensing computation capability of the first node 210. In such implementations, the node 240 in the core network 106 may not provide, to the first node 210, the request for the sensing report level or sensing computation capability of the first node 210. The first node 210 may provide, to the base station 102, computation capability of the first node 210 based on the period.
[0176] Some implementations of the request or configuration associated with the sensing report level or sensing computation capability have been described with reference to Figs. 4 to 7. Such implementations are applicable to the process 800. Details of such implementations are omitted for brevity.
[0177] Some implementations of the information associated with the sensing report level or sensing computation capability have been described with reference to Figs. 4 to 7. Such implementations are applicable to the process 800. Details of such implementations are omitted for brevity.
[0178] Fig. 9 illustrates an example of a device 900 that supports cooperative sensing in accordance with aspects of the present disclosure. The device 900 may be an example of a network entity 102 as described herein. The device 900 may support wireless communication with one or more network entities 102, UEs 104, or any combination thereof.
