CONFIGURATION METHOD AND RELATED APPARATUSES FOR SENSING MEASUREMENTTECHNICAL FIELD
[0001] The present disclosure relates to the field of communication technologies, and in particular, to a configuration method and related apparatuses for sensing measurement.BACKGROUND
[0002] With the large-scale popularization of Internet applications and wireless network devices, people’s demand for wireless communication further increases. Communications technologies are also evolving, from 4G to 5G to next-generation communications. The communication spectrum ranges from low to high frequency bands such as decimeter wave, centimeter wave, millimeter wave, terahertz. With increased frequency, a higher number of antennas and larger bandwidth can be used for wireless transmission and reception. These are not only beneficial for communication, but also for sensing. Wireless sensing as a new technology including a wide range of applications such as object detection, ranging, positioning, tracking, imaging, etc., is gaining popularity.
[0003] 5G supports large bandwidth spectrum for throughput enhancement. However, the higher throughput also increases energy consumption for user equipment (UE) , potentially shortening battery life. In order to reduce power consumption, 5G supports both downlink control information (DCI) -based wake-up signal (WUS) and sequence-based WUS for UE power saving. The WUS can be transmitted before a time offset of discontinuous reception (DRX) ON time duration. If a WUS is received, the UE will monitor the physical downlink control channel (PDCCH) in the following DRX ON duration. Otherwise, the UE will skip the entire DRX ON duration and continue in a sleep state, thus minimizing the energy consumption. The WUS can also be transmitted before a paging occasion (PO) . For this case, the WUS can be a kind of paging early indication (PEI) DCI. If the WUS indicates a valid PO for a UE, the UE will monitor the PDCCH in the PO. Otherwise, the UE will remain in the sleep state with a reduced power consumption. To further reduce power consumption, 5G has also introduced a separate wake-up receiver (WUR) . When the UE monitors a low power (LP) WUS using a WUR, the main radio (MR) is in the sleep state, and therefore the power consumption is reduced. Once the WUS is received with the WUR, the UE can wake up the MR for PDCCH monitoring.
[0004] This background information is provided to reveal information believed by the applicant to be of possible relevance to the present disclosure. No admission is necessarily intended, nor should be construed, that any one of the preceding information constitutes prior art against the present disclosure.SUMMARY
[0005] In a first aspect, according to an embodiment of the present disclosure, a method is provided. The method can be a configuration method. The method is applied to a first device, and the method includes: receiving a first indication, where the first indication indicates sensing information and a first qualification requirement, wherein the first qualification requirement is used for determining whether the first device is qualified to perform sensing measurement on at least one signal segment of a sensing signal based on the sensing information; wherein resource elements of the sensing signal include resource elements of plurality of signal segments of the sensing signal.
[0006] By introducing a nested sensing signal structure, the solution allows for flexible allocation of sensing signal resources to different terminal devices based on their capabilities. This dynamic resource allocation reduces wastage of resources and enhances the overall efficiency of resource allocation. The terminal device can be woken up for sensing measurements if they meet specific qualification requirements, thus reducing unnecessary wake-ups and power usage.
[0007] In an implementation of the first aspect, the plurality of signal segments are distributed in one or more bandwidth (BW) sets, and each BW set of the one or more BW sets is associated with one or more signal segments.
[0008] In an implementation of the first aspect, a BW set includes identification information of one or more signal segments, and the BW set including the identification information of one or more signal segments can also be referred to as a segment set.
[0009] In an implementation of the first aspect, the association between each BW set and the one or more signal segments is indicated in the first indication or a sensing response.
[0010] In an implementation of the first aspect, for each signal segment of the plurality of signal segments, a frequency position of the signal segment is indicated by a frequency offset relative to a reference sensing signal.
[0011] The nested structure allows for flexible allocation of sensing resources, accommodating a wide range of UE capabilities and sensing requirements. By segmenting the sensing signal bandwidth, the network can optimize resource usage and reduce wastage, improving overall system performance. Several independent assignment of different BW sensing reference signal (SERS) resources can be avoided.
[0012] In an implementation of the first aspect, the sensing information indicates configuration information of the plurality of signal segments and a first reporting resource for a first sensing report. The method further includes: when the first qualification requirement is met, performing sensing measurement on the at least one signal segment according to the configuration information of the plurality of signal segments; transmitting the first sensing report using the first reporting resource, wherein the first sensing report includes a sensing measurement result based on the at least one signal segment. Both overhead and power consumption is reduced with the one-step sensing measurement report generation procedure.
[0013] In an implementation of the first aspect, the sensing information indicates configuration information of the plurality of signal segments, a first reporting resource for a first sensing report, and a first occasion for monitoring a second indication.
[0014] In an implementation of the first aspect, the second indication indicates a second qualification requirement, and the second qualification requirement is part of the first qualification requirement. The method includes: when the second qualification requirement is met, performing sensing measurement on the at least one signal segment according to the configuration information of the plurality of signal segments; transmitting the first sensing report using the first reporting resource, wherein the first sensing report includes a sensing measurement result based on the at least one signal segment. The qualification index-specific reporting resource can reduce the collision between the reporting resources. If the UE does not meet the requirements, the UE will stop the PDCCH detection (the detection of the first indication) following the second indication. Since the UE does not have to perform detection unnecessarily in this case, the power consumption can be reduced. Moreover, the qualified terminal device reports sensing results in BW segment-specific resources, and the unqualified terminal device can continue to remain in the sleep state. The reporting resources are segment-specific and configured to avoid collision between the reporting resources .
[0015] In an implementation of the first aspect, the method further includes receiving the second indication in the first occasion.
[0016] In an implementation of the first aspect, the second qualification requirement indicates one or more BWs, and the one or more BWs belong to one or more BW sets indicated in the first qualification requirement. The second indication can provide specific or updated requirements that the terminal device needs, in order perform the sensing measurements. The second indication can dynamically update the qualification requirements based on real-time network conditions or specific sensing task requirements.
[0017] In an implementation of the first aspect, the second indication includes identification information of each of the one or more BW sets. In this way, the indication capacity for the indication of BW sets can be reduced.
[0018] In an implementation of the first aspect, the configuration information of the plurality of signal segments includes a time offset of a second occasion for receiving the sensing signal relative to the first occasion.
[0019] In an implementation of the first aspect, the sensing information indicates a first reporting resource for a first sensing report. The method further includes: when the first qualification requirement is met, transmitting a first sensing report using the first reporting resource; receiving a sensing response, wherein the sensing response indicates configuration information of the at least one signal segment and a second reporting resource for a second sensing report; performing sensing measurements on the at least one signal segment; transmitting the second sensing report using the second reporting resource, wherein the second sensing report includes a sensing measurement result based on the at least one signal segment. Parameters such as the signal segment’s configuration may not be included. The sensing BW (i.e., the BW on which the terminal device performs sensing measurements) can be reported in the preamble and data, which allows the network to configure signal segment’s BW in the following sensing response signaling. By configuring the signal segments based on the sensing report from the terminal device, the network can avoid assigning bandwidths that the terminal device cannot support or that are inefficient for the terminal device’s capabilities, therefore undesirable sensing signal configurations can be avoided. After transmission of the preamble and data, beam-specific sensing signal configuration can be used to avoid undesirable sensing signal beam transmission, thus reducing the consumption of both energy and resources.
[0020] In an implementation of the first aspect, the sensing information indicates a first reporting resource for a first sensing report and a first occasion for monitoring a second indication.
[0021] In an implementation of the first aspect, the second indication indicates a second qualification requirement, and the second qualification requirement is part of the first qualification requirement.

In comparison with the one-step sensing measurement report generation method, parameters such as the signal segment’s configuration may not be included. The qualification index-specific reporting resource can reduce collision between the reporting resources. The UE which does not meet the requirements will stop the PDCCH detection (the detection of the first indication) following the second indication. Since the UE does not have to perform detection unnecessarily in this case, the power consumption can be reduced. Moreover, the qualified terminal device reports sensing results in BW segment-specific resources, and the unqualified terminal device can continue to remain in the sleep state. The reporting resources are segment-specific configured to avoid collision between reporting resources. The sensing BW is reported by preamble and data, which allows the network to configure signal segment’s BW in the following sensing response signaling. By configuring the signal segments based on the sensing report from the terminal device, the network can avoid assigning bandwidths that the terminal device cannot support or that are inefficient for the terminal device’s capabilities. After transmission of the preamble and data, beam-specific sensing signal configuration can be used to avoid undesirable sensing signal beam transmission, thus reducing the consumption of both energy and resources.

[0144] The embodiments of the present disclosure are described below with reference to the accompanying drawings.
[0145] In the following description, reference is made to the accompanying figures, which form part of the present disclosure, and which show, by way of illustration, specific aspects of one or more embodiments or examples of the present disclosure or specific aspects in which one or more embodiments or examples of the present disclosure may be used. It is understood that the embodiments or examples of the present disclosure may be used in other aspects and include structural or logical changes that may not be depicted in the figures. The following detailed description, therefore, is not to be taken in a limiting sense, and the scope of the present disclosure is defined by the appended claims.
[0146] Examples of wireless communication systems and devices are described below.
[0147] FIG. 1 is a simplified schematic illustration of a communication system according to one or more embodiments of the present disclosure. Referring to FIG. 1, as an illustrative example, a simplified schematic illustration of a communication system 100 is provided. The communication system 100 may comprise a radio access network 120. The radio access network (RAN) 120 may be a next generation (e.g. 6th generation (6G) or later) radio access network, or a legacy (e.g. 5th generation (5G) , 4th generation (4G) ) radio access network. In some implementations, 6G radio access refers to a next generation air interface of standards which may comprise both terrestrial networks (TNs) and non-terrestrial networks (NTNs) , and more details will be described below. One or more communication electronic device (ED) 110a, 110b, 110c, 110d, 110e, 110f, 110g, 110h, 110i, 110j (generically referred to as 110) may be interconnected to one another or connected to one or more network nodes 170a, 170b (generically referred to as 170) in the RAN 120. A core network (CN) 130 may be a part of the communication system and may be dependent or independent of the radio access technology used in the communication system 100. The communication system 100 may also comprise a public switched telephone network (PSTN) 140, the internet 150, and other networks 160.
[0148] In general, the communication system 100 enables communication of multiple wireless or wired elements. The communication system 100 may provide content, such as voice, data, video, and / or text, via broadcast, multicast, groupcast, unicast, etc. The communication system 100 may operate by sharing resources, such as carrier spectrum bandwidth, among its constituent elements.
[0149] The communication system 100 may provide a wide range of communication services and applications including enhanced Mobile Broadband (eMBB) services, ultra-reliable low-latency communication (URLLC) services, massive machine type communication (mMTC) services, integrated sensing and communication (ISAC) , immersive communication, massive communication, Hyper reliable and low-latency communication, ubiquitous connectivity, integrated AI and communication, and other services that can be provided by a future generation communication system. The communication system 100 may provide other services and applications such as earth monitoring, remote sensing, passive sensing and positioning, navigation and tracking, autonomous delivery and mobility, etc.
[0150] FIG. 2 is a schematic illustration of another example communication system according to one or more embodiments of the present disclosure. As described earlier, the communication system 100 may include ED 110a, 110b, 110c, 110d (generically referred to as ED 110) , RAN 120a, 120b, and one or more of a CN 130, a PSTN 140, the internet 150, and other networks 160. In addition, the communication system 100 may also include a non-terrestrial network (NTN) 120c. The RANs 120a, 120b may include respective network nodes 170a, 170b such as base stations 170a, 170b, which may be generically referred to as terrestrial network (TN) devices or terrestrial transmit and receive points (T-TRPs) 170a, 170b (generically referred to as 170) . As referred to herein, the terms “TRP” and “base station” may be used interchangeably unless explicitly noted otherwise in a given example or section. For brevity, this disclosure may primarily refer to base station; however, absent an explicit limitation, references to TRP are merely non-limiting instances of interchangeable use. The T-TRPs 170a, 170b may be base stations mounted on a building or tower. In one implementation, the NTN 120c includes a RAN node such as base station 172, which may be generically referred to as an NTN device, a non-terrestrial node, a non-terrestrial network device, a non-terrestrial base station, or a non-terrestrial transmit and receive point (NT-TRP) 172.
[0151] A base station (also referred to TRP as stated above) 170 may be a network element in radio access network responsible for radio transmission and reception in one or more cells to or from the user equipment. Base station 170 may be known by other names in some implementations, such as a base transceiver station (BTS) , a radio base station, a network node, a network device, a device on the network side, a transmit / receive node, a Node B, an evolved NodeB (eNodeB or eNB) , a Home eNodeB, a next Generation NodeB (gNB) , a transmission point (TP) , a site controller, an access point (AP) , a wireless router, a relay station, a terrestrial node, a terrestrial network device, a terrestrial base station, a positioning node, among other possibilities. The base station 170 may be a macro base station (BS) , a pico BS, a relay node, a donor node, or the like, or combinations thereof. When a base station 170 performs (or is configured to perform) a method described herein, it may be interpreted as the base station, one or more modules (or units) in the base station, a circuit or chip, or a combination thereof, may perform the method. For example, the circuit or chip may include a modem chip, also referred to as a baseband chip, a system on chip (SoC) including a modem core, system in package (SIP) ) , and the like, and may be responsible for one or more communication functions in the base station.
[0152] Any base station may be a single element, as shown, or multiple elements, distributed in the corresponding RAN, or otherwise. In some implementations, a plurality of RAN nodes coordinate to assist the ED 110 in implementing radio access, and different RAN nodes separately implement different functions of the base station. For example, the RAN node may be a central unit (CU) , a distributed unit (DU) , a CU-control plane (CP) , a CU-user plane (UP) , or a radio unit (RU) etc. The CU and the DU may be separately deployed, or may be included in a same element (i.e., a baseband unit (BBU) ) . The RU may be included in a radio frequency device or a radio frequency unit (i.e., a remote radio unit (RRU) , an active antenna unit (AAU) , or a remote radio head (RRH) ) .
[0153] The ED 110 is used to connect persons, objects, machines, etc. The ED 110 may be widely used in various scenarios including, for example, cellular communications, device-to-device (D2D) , vehicle to everything (V2X) , peer-to-peer (P2P) , machine-to-machine (M2M) , MTC, internet of things (IoT) , virtual reality (VR) , augmented reality (AR) , mixed reality (MR) , metaverse, digital twin, industrial control, self-driving, remote medical, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, drones, robots, remote sensing, passive sensing, positioning, navigation and tracking, autonomous delivery and mobility, etc.
[0154] Each ED 110 represents any suitable end user device for wireless operation and may include such devices (or may be referred to but not limited to) as a user equipment (UE) or a user device or a terminal device, a wireless transmit / receive unit (WTRU) , a mobile station, a fixed or mobile subscriber unit, a cellular telephone, a station (STA) , a MTC device, a personal digital assistant (PDA) , a smartphone, a laptop, a computer, a tablet, a wireless sensor, a consumer electronics device, a smart book, a vehicle, a car, a truck, a bus, a train, or an IoT device, wearable devices (such as a watch, a pair of glasses, head mounted equipment, etc. ) , an industrial device, or an apparatus in (e.g. module, modem, or chip) or comprising the forgoing devices, among other possibilities. Future generation EDs 110 may be referred to using other terms. When an ED 110 performs (or is configured to perform) a method described herein, it may be interpreted as the ED, one or more module (or units) in the ED, a circuit or chip, or a combination thereof, may perform the method. For example, the circuit or chip may include a modem chip, also referred to as a baseband chip, a system on chip (SoC) including a modem core, or system in package (SIP) ) , and the like, and may be responsible for one or more communication functions in the ED.
[0155] An air interface (e.g., 190a, 190b, 190c) generally includes a number of components and associated parameters that collectively specify how a transmission is to be sent and / or received over a wireless communications link between two or more communicating devices such as ED and base station. For example, an air interface may include one or more components defining the waveform (s) , frame structure (s) , multiple access scheme (s) , protocol (s) , coding scheme (s) and / or modulation scheme (s) for conveying information (e.g., data) over a wireless communications link. The air interfaces 190a and 190b may use similar communication technology, such as any suitable radio access technology.
[0156] The RANs 120a and 120b are in communication with the CN 130 to provide the EDs 110a 110b, and 110c with various services such as voice, data, and other services. The RANs 120a and 120b and / or the CN 130 may be in direct or indirect communication with one or more other RANs (not shown) , which may or may not be directly served by CN 130, and may or may not employ the same radio access technology as RAN 120a, RAN 120b or both. The CN 130 may also serve as a gateway access between (i) the RANs 120a and 120b or EDs 110a 110b, and 110c or both, and (ii) other networks (such as the PSTN 140, the Internet 150, and the other networks 160) . In addition, some or all of the EDs 110a 110b, and 110c may include functionality for communicating with different wireless networks over different wireless links using different wireless technologies and / or protocols. Instead of wireless communication (or in addition thereto) , the EDs 110a 110b, and 110c may communicate via wired communication channels to a service provider or switch (not shown) , and to the Internet 150. PSTN 140 may include circuit switched telephone networks for providing plain old telephone service (POTS) . Internet 150 may include a network of computers and subnets (intranets) or both, and incorporate protocols, such as internet protocol (IP) , transmission control protocol (TCP) , user datagram protocol (UDP) . EDs 110a 110b, and 110c may be multimode devices capable of operation according to multiple radio access technologies, and incorporate multiple transceivers necessary to support such.
[0157] In addition, the communication system 100 may comprise a sensing agent (not shown) to manage the sensed data from ED 110 and / or any one of TRPs 170 a-170b, 172. In one implementation, the sensing agent may be part of any one of TRPs 170 a-b, 172. In another implementation, the sensing agent is a separate node that can communicate with the CN 130 and / or the RAN 120 (e.g., any one of TRPs 170 a-b, 172) .
[0158] The RAN can be a 3GPP-related cellular system, such as the 5G mobile communication system or future evolution systems (e.g., 6G mobile communication systems) . RAN can also be an open radio access network (O-RAN) , cloud radio access network (CRAN) , or Virtualized Radio Access Network (vRAN) , etc. Additionally, RAN can be a communication system that integrates two or more of the aforementioned systems. The RAN devices can also be referred to as RAN node, RAN entity, or access node, etc.
[0159] In a possible scenario, the RAN node can be a base station, an evolved NodeB (eNodeB) , an access point (AP) , transmission reception point (TRP) , a next-generation NodeB (gNB) , a next-generation base station in the 6G mobile communication system, a base station in a future mobile communication system, and so on. The RAN node can be a macrocell, microcell, an indoor station, a relay node, a donor / host node, or a wireless controller, etc. The RAN node can also be server, wearable device, vehicle, or vehicular device, etc. For example, in V2X technology, a RAN node can be a roadside unit (RSU) .
[0160] In another possible scenario, the RAN node can be a module or unit that performs part of the base station’s functions; or multiple RAN nodes can collaborate to assist terminal devices in achieving wireless access, with different RAN nodes implementing part of the base station’s functions. For example, the RAN node can be a central unit (CU) , a distributed unit (DU) , or a radio unit (RU) , etc. The functions of the CU can be implemented by a single entity or by different entities. For instance, the functions of the CU can be further divided, that is, separating the control plane and user plane to be implemented by different entities, namely the control plane CU entity (i.e., CU-Control Plane (CP) entity) and the user plane CU entity (i.e., CU-user plane (UP) entity) . The CU-CP entity and CU-UP entity can be coupled with the DU to jointly complete the functions of the RAN node. The CU and DU can be set up separately or can also be included in the same network element, such as a baseband unit (BBU) .
[0161] In different systems, CU (or CU-CP and CU-UP) , DU, or RU may also have different names, but those skilled in the field can understand their meanings. For example, in an O-RAN system, CU can also be referred to as O-CU (Open CU) , DU can also be referred to as O-DU, CU-CP can also be referred to as O-CU-CP, CU-UP can also be referred to as O-CU-UP, and RU can also be referred to as O-RU. For convenience of description, CU, CU-CP, CU-UP, DU, and RU are used in the present disclosure as examples. Any unit of the CU (or CU-CP, CU-UP) , DU, and RU in the present disclosure can be implemented through software modules, hardware modules, or a combination of software and hardware modules.
[0162] CU and DU can be configured based on protocol layer functions they implement in the wireless network. For example, CU is configured to implement functions of a packet data convergence protocol (PDCP) layer and aforementioned protocol layers (such as a radio resource control (RRC) layer and / or service data adaptation protocol (SDAP) layer, etc. ) . DU is configured to implement the functions of the protocol layers below the PDCP layer (such as the radio link control (RLC) , media access control (MAC) layer, and / or physical (PHY) layer, etc. ) . Alternatively, CU is configured to implement the functions of the protocol layers above the PDCP layer (such as the RRC layer and / or SDAP layer) , and DU is configured to implement the functions of the protocol layers below the PDCP layer (such as the RLC layer, MAC layer, and / or PHY layer, etc. ) . For specific descriptions of the aforementioned protocol layers, reference can be made to the relevant technical specifications of 3GPP or other applicable technical specifications of communication protocols. The division of CU and DU functions according to protocol layers is just an example, and other methods of division are also possible, and this application does not limit it. For example, in one design, CU or DU can also be divided into having partial processing functions of the protocol layer. In one design, part of the functions of the RLC layer and the functions of the protocol layers above the RLC layer are set in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are set in the DU.
[0163] FIG. 3 illustrates an example of an apparatus 320 in a communication system (e.g., a future generation network architecture illustrated in FIG. 2) according to one or more embodiments of the present disclosure. The apparatus 320 may be a UE, a network node such as the AN, any components in the AN, the CN or any Network Function of the CN (AMF+, SMF+or any other network functions illustrated in FIG. 2) . As shown in FIG. 3, the apparatus 320 may include at least one processor 260. Only one processor 260 is illustrated to avoid congestion in the drawing. The processor 260 may perform (or control the apparatus 320 to perform) operations (or methods) described herein as being performed by the apparatus 320.
[0164] When the apparatus is the AN, components of the AN or the apparatus is the UE, the apparatus 320 may further include a transmitter 252 and a receiver 254 coupled to one or more antennas. One, some, or all of the antennas may alternatively be panels. The transmitter 252 and the receiver 254 may be integrated, e.g. as a transceiver. The transceiver is configured to modulate data or other content for transmission by at least one antenna or a network interface controller (NIC) . The transceiver is also configured to demodulate data or other content received by the at least one antenna. Each transceiver includes any suitable structure for generating signals for wireless or wired transmission and / or processing signals received wirelessly or by wire. Each antenna includes any suitable structure for transmitting and / or receiving wireless or wired signals. In present disclosure, the transceiver (or transmitter 252 and / or receiver 254) may be viewed as an interface circuit.
[0165] The apparatus 320 may include at least one memory 258. The memory 258 stores instructions used to perform operations described herein. The memory 258 may also store data used, generated, or collected by the apparatus 320. For example, the memory 258 could store software instructions or modules configured to implement some or all of the functionality and / or embodiments described herein and that are executed by the one or more processors 260.
[0166] It should be noted that in present application, “information” , when different from “message” , may be carried in one single message, or be carried in multiple separate messages.
[0167] FIG. 4 is a schematic illustration of an apparatus in a communication system according to one or more embodiments of the present disclosure. FIG. 4 illustrates an example of an apparatus 410. The apparatus 410 may be a communication device or an apparatus implemented in a communication device such as ED 110 or TRPs 170a-170b, 172. For example, the apparatus implemented in a communication device may be an integrated circuit, which in some contexts may be known by other colloquial names, such as chip, modem, modem chip, baseband chip, or baseband processor. In some implementations, one or more integrated circuits can be packaged into a system-on-chip, a system-in-package, or a multi-chip module. The apparatus may comprise one or more integrated circuits or comprise one or more integrated circuits and other discrete components. In some implementations, the apparatus 410 may be a module in ED 110, or apparatus 320. In some implementations, the apparatus 410 may be a module in one of TRPs 170a-170b, 172, or apparatus 320.

The one or more processors / processor cores 411 are configured to process signals and execute one or more communication protocols. The memory 413 is configured to store at least a part of corresponding computer program instructions and / or data. In an example, the one or more processors (or processor cores) 411 execute the computer program instructions stored in the memory 413 to implement related operations (for example, inputting, outputting, receiving, and transmitting) in the foregoing method embodiments. In some implementations, the memory 413 being configured to store the corresponding computer program instructions and / or data may mean that the memory 413 is configured to store all of the corresponding computer program instructions and / or data for execution by the one or more processors / processor cores 411. In some implementations, the memory 413 being configured to store the corresponding computer program instructions and / or data may mean that the memory 413 is configured to store a part of the corresponding computer program instructions and / or data. For example, the part of the corresponding computer program instructions and / or data include computer program instructions and / or data that need to be currently executed by the one or more processors / processor cores 411. Thus, the memory 413 may store different parts of computer program instructions and / or data for a plurality times for the one or more processors (or processor cores) 411 to perform related operations in the foregoing method embodiments. As a communication interface, the interface circuit 412 is configured to implement communication with another component. For example, the interface circuit 412 may communicate a signal with other apparatus / system such as a radio frequency processing apparatus, or processor system. Optionally, to reduce a load of the processor core, a baseband signal processing circuit 414 may be also disposed to implement processing of at least a part of baseband signals, including signal demodulation, modulation, encoding, decoding, or the like.
[0169] Apparatus 410 may be processor 260 in apparatus 320, in some scenario, or included in processor 260 in apparatus 320 in some scenario. Apparatus 410 may be or include a baseband chip. In some implementations, the apparatus 410 may be independently packaged into a chip. In some implementations, the apparatus 320 includes different types of chips. The apparatus 410 may be packaged into a processor chip (for example, a SoC chip or an SIP chip) with the different types of chips. In some implementations, the apparatus 410 may be packaged into a chip with some or all of circuits of a radio frequency processing system that may further included in the apparatus 320.

In some implementations, the apparatus 510 includes a processing unit 512 and a communication unit 513. Optionally, the apparatus 510 may further include a storage unit 514 configured to store apparatus program code (or instructions) and / or data.
[0171] The apparatus 510 may be an ED side apparatus, for example, an ED or a module in an ED, or a circuit or a chip responsible for a communication function in an ED. In some implementations, apparatus 510 may be implemented as apparatus 320, accordingly, the processing unit 512 is implemented as processor 260, the communication unit 513 is implemented as transmitter 252 and / or receiver 203, and the storage unit 514 is implemented as memory 208.
[0172] The apparatus 510 may be a CN side apparatus or a base station side apparatus, for example, a base station or a module in a base station, or a circuit or a chip responsible for a communication function in a base station. In some implementations, apparatus 510 may be implemented as apparatus 320, accordingly, the processing unit 512 is implemented as processor 260 (the scheduler 253 may also be included) , the communication unit 513 is implemented as transmitter 252 and / or receiver 254, and the storage unit 514 is implemented as memory 258.
[0173] In some implementations, when the apparatus 510 is an ED 110 or a module in an ED 110, a function of the apparatus 510 may be implemented by one or more processors. Specifically, the processor may include a modem chip, or a system on chip SoC chip or an SIP chip that includes a modem core. A function of the communication unit 513 may be implemented by a transceiver circuit.
[0174] In some implementations, when the apparatus 510 is a circuit or a chip that is responsible for a communication function in a ED 110, for example, a modem chip, a system on chip SoC chip or an SIP chip that includes a modem core, a function of the processing unit 512 may be implemented by a circuit system that is in the chip and that includes one or more processors or processor cores. A function of the communication unit 513 may be implemented by an interface circuit or a data transceiver circuit on the foregoing chip.
[0175] It may be understood that division into the units in the foregoing apparatus is merely logical function division. Each function may correspond to one functional unit, or two or more functions may be integrated into one functional unit. In actual implementation, all or some of the units may be integrated into one physical entity, or may be distributed in different physical entities. In addition, the foregoing functional units may be implemented in a form of hardware, may be implemented in a form of software, or may be implemented in a form of a combination of hardware and software. Whether a function is performed in a form of hardware or software depends on particular applications and design constraint conditions of the technical solutions. A person skilled in the art may use different methods to implement the described functions for each particular application, but it should not be considered that the implementation goes beyond the scope of this application.

[0180] The solution described in the present disclosure may be applicable to a next generation (e.g. sixth generation (6G) or later) network, or a legacy (e.g. 5G, 4G) network.
[0181] Two types of contention-based random access (CBRA) procedures are supported in 5G networks: the two-step and four-step random access (RA) procedures. These procedures are essential for a UE to establish a connection with the network, especially when switching from a low-power sleep state to an active state for data transmission. Below is a detailed explanation of each of the procedures.
[0182] A message 1 of the two-step RA type includes a preamble on a physical random access channel (PRACH) and a payload on a physical uplink shared channel (PUSCH) . After message A transmission, the UE monitors the response from the network. The network responds with a message (e.g., a message B) that includes the necessary grants and timing information.
[0183] The four-step random access procedure is a method used in 5G networks for a UE to request access to the network. The UE sends message 1 to the gNB. The message 1 of the four-step RA type consists of a preamble on PRACH. After the transmission of message 1, the UE monitors a grant response from the network. The network responds with a Random Access Response (RAR) (e.g., message 2) on the PDCCH (Physical Downlink Control Channel) . The RAR includes a grant for uplink resources, a temporary UE identifier (e.g., a Temporary C-RNTI) , and timing advance information. The UE then performs transmission of message 3 using the UL grant scheduled in the response and monitors contention resolution. The network sends a contention resolution message (e.g., message 4) to the UE. The message 4 is used to confirm that the network has successfully identified the UE and resolved any potential conflicts. The UE is now fully connected to the network and can proceed with data transmission.
[0184] In 5G, it is assumed that the UE can initiate initial access procedures for fast data transmission when switching from a low power sleeping state to main radio transmission.
[0185] However, in 5G power saving modes, sensing capabilities may not be considered. Currently, there may be no clearly defined approaches to support sensing within the power-saving procedures of 5G networks, such as, for example, techniques to support sensing measurement and reporting when considering the power saving aspects are not quite straightforward. In some scenarios, sensing tasks may need to be broadcast transmission-based, meaning that multiple UEs may need to perform sensing simultaneously or based on common reference signals. Allocating resources for broadcast sensing while maintaining power efficiency is complex. Current mechanisms do not provide clear approaches to handle such resource assignments.
[0186] In view of the above, the present disclosure provides a method applied to a first device (which may be the abovementioned terminal device) , in which a first indication is used to indicate sensing information and a first qualification requirement. The first qualification requirement is used for determining whether the first device is qualified to perform sensing measurement on at least one signal segment of a sensing signal based on the sensing information. The sensing signal is designed to have plurality of signal segments, and resource elements of the sensing signal include resource elements of plurality of signal segments of the sensing signal. The at least one signal segment based on which the sensing measurement is performed is included in the plurality of signal segments. By introducing signal segments, the solution allows for a flexible allocation of sensing signal resources to different terminal devices based on their respective capabilities. The dynamic resource allocation can reduce resource wastage and enhance overall efficiency of resource allocation. The terminal device can be woken up for sensing measurements if they meet specific qualification requirements, thus reducing unnecessary wake-ups and power usage.
[0187] In some cases, a low-power state UE sensing report can be supported with either the one-step or the three-step sensing measurement report generation method. The LP-WUS is used to indicate sensing qualification bandwidth (BW) set and activate the SERS, the sensing qualification requirement and the sensing reference signal (SERS) configurations are from sensing system information (SI) . In some cases, nested structure SERS is introduced with the segment SERS sharing part BW of reference SERS for UEs with different BW capabilities, to reduce SERS resource consumption. The sensing measurement report resources are segment BW-specific configuration. According to the sensing SI and the LP-WUS, the qualified UE measures the SERS and reports the sensing results and the associated BW index in the sensing report. The sensing report resources can be a segment BW-specific configuration.
[0188] Solutions provided by embodiments of the present disclosure can be applied to a communication system including a sensing device. The sensing device can be a device with sensing capabilities, such as, for example, a terminal device with sensing capabilities. The sensing device can also be referred to as a sensing apparatus, a detector, or by other equivalent terms. The sensing device can determine attribute information of a target to be sensed by transmitting a signal (which can also be referred to as a sensing signal) and receiving the signal (also known as an echo signal) reflected by the target to be sensed. Alternatively, the sensing device can forward a measurement result of the echo signal to a further device. The further device then determines the attribute information of the target to be sensed. The attribute information of the target to be sensed includes information such as speed, distance, attitude, shape, size, and position of the target. The sensing signal, which is used to sense the target to be sensed, may also be referred to as a detection signal, a radar signal, a radar sensing signal, a radar detection signal, an environmental sensing signal, a reference signal, or other equivalent terms. The sensing signal can be a pulse signal or a signal that may be present in a wireless communication system, such as a sounding reference signal (SRS) , a demodulation reference signal (DMRS) , a channel state information reference signal (CSI-RS) , a synchronization signal (SS) and physical broadcast channel (PBCH) block (synchronization signal / PBCH block, SSB) , or an SS.
[0189] The embodiments of the present disclosure can be applied to sensing of the surrounding environment. For example, the embodiments of the present disclosure can be applied to ground traffic detection, to detect vehicle speed, whether a vehicle is occupying an emergency lane, or whether a vehicle is changing lanes illegally. In this scenario, the sensing device can be installed on mobile devices, such as motor vehicles (e.g., autonomous vehicles, smart cars, electric vehicles, digital cars, etc. ) , drones, rail cars, bicycles, speed measurement devices, terminal devices, etc. The sensing device can also be installed on fixed devices, such as roadside devices or traffic lights, etc. Additionally, other example applications include air traffic detection, meteorological detection, safety detection, electromagnetic imaging, etc. It is to be understood that examples may not be limited to only sensing application scenarios.
[0190] An exemplary scenario of the present disclosure will be described prior to elaborating the solution of the present disclosure. It should be noted that FIG. 6 shows an exemplary scenario to which the solution proposed by the present disclosure could be applied, and should not be construed as a limitation.
[0191] FIG. 6 is a schematic diagram of an application scenario according to one or more embodiments of the present disclosure. FIG. 7 is a schematic diagram of a sensing entity deployment according to one or more embodiments of the present disclosure. As shown in FIG. 6 and FIG. 7, the embodiment provides two network devices including a core network and a base station and at least one sensing device (e.g., a UE) , the number of network devices and UEs. The entities shown in FIG. 6 and FIG. 7 are illustrative rather than restrictive. Sensing configurations are established by a sensing entity located either in the CN or the RAN node. The sensing entity is responsible for the management of sensing tasks, allocation of sensing resources, and for calculation of sensing results. The configuration of the sensing entity can be directed by the CN, the RAN, or both. The sensing entity in the RAN can be configured by the CN. A sensing report, which may be generated based on measurement of a sensing signal, is transmitted from the UE to the sensing entity in the CN or the RAN node. The RAN node can process the sensing report locally or forward the sensing report to the CN which then processes the sensing report. The transmission of sensing information between the CN-based sensing entity and the UE is facilitated by the LPP (LTE Positioning Protocol) . The sensing information may be information about how to perform sensing measurements by the UE. The RAN node can be a base station or another UE. In the case of direct communication between two UEs, the transmission of the sensing information can occur over a sidelink connection. For sidelink sensing, the sensing entity may be located in the CN or the UE for establishing the sensing configuration. The sensing entity in the UE can be configured by the CN. The communication between the UE and the CN node can be implemented via new radio (NR) positioning protocol ‘a’ (NRPPa) .
[0192] The transmission of sensing information between the base station and the UE can be performed over a Uu link (which may be the direct radio link between the UE and the base station) . If sensing is configured by the CN, the transmission of sensing information between the CN and the UE can be done over a CN and UE interface. Alternatively, the configuration can be transmitted to the RAN node, which then communicates with the UE.
[0193] As shown in FIG. 6 and FIG. 7, an object is to be sensed. The object could be the aforementioned target to be sensed. For example, the base station transmits radio signals that propagate through the environment. These signals can directly reach the UE and can also reflect off objects such as buildings. The UE may receive both the direct signal from the base station and the reflected signal from the object. The UE can measure various properties of these signals, such as phase, angle of arrival, time of arrival, and signal strength. The phase difference between the direct and reflected signals can provide information about the path length difference. This can be used to calculate the distance to the object. The time difference between the transmission of the signal and its reception can also be used to calculate the distance to the object. If the object is moving, the frequency of the reflected signal will be shifted due to the Doppler effect. The frequency can be used to determine the speed and direction of the object. The UE can process the measured data to extract relevant information about the object, such as its distance, speed, and direction. The UE generates a sensing report that includes these attributes and transmits it back to the base station.
[0194] The method provided in embodiments of the present disclosure can be executed by a first device and a second device, wherein the first device can perform functions of a terminal device, and the second device can perform the functions of a network device. For example, the first device can be the UE in FIG. 6 or FIG. 7, and the second communication device can be the network device shown in FIG. 6, or FIG. 7. Alternatively, the first device can perform functions of a terminal device, and the second device can also perform functions of a network device. For example, the first device can be the UE in FIG. 6 or FIG. 7, and the second communication device can also be the network device in FIG. 6 or FIG. 7.
[0195] For ease of description, in the following text, examples are taken where the embodiments are executed by a network device and a terminal device, but the execution body should not be limited to a network device and a terminal device. For example, the embodiment can also involve interactions between one network device and multiple terminal devices. When involving multiple terminal devices, each of these terminal devices may follow the same or similar process flow to participate in the same sensing task, or may take different actions to complete different sensing tasks.
[0196] In the communication method provided by the embodiment, steps executed by the network device can be realized by a RAN device or a CN itself or by components within the RAN device or the CN device (such as a baseband chip, or other processing units or processors, etc. ) . For example, the network device can be the network device in FIG. 6, or it can also be the chip (system) within the network device in FIG. 6. The steps executed by the terminal device can be realized by a terminal device itself or by components within the terminal device (such as a chip, a processing unit, or a processor, etc. ) . The terminal device can be the UE shown in FIG. 6, or it can also be the chip (system) within the UE in FIG. 6.
[0197] FIG. 8 is a schematic flowchart of a method for sensing measurement according to one or more embodiments of the present disclosure. The method shown in FIG. 8 illustrates the interaction between a network device and a terminal device. In an example, the terminal device can be referred to as a first device, and the network device can be referred to as a second device. It should be understood that the method shown in FIG. 8 can also be realized by other devices, such as chips or communication devices with communication capabilities. As shown in FIG. 8, the method can include the following steps.
[0198] At S801, the network device transmits a first indication, and the terminal device receives the first indication. The first indication indicates sensing information and a first qualification requirement, the first qualification requirement is used for determining whether a first device is qualified to perform sensing measurement on at least one signal segment (also referred to as a sensing segment) of a sensing signal based on the sensing information, wherein resource elements of the sensing signal comprise resource elements of plurality of signal segments of the sensing signal.
[0199] In an implementation, the network device may broadcast, groupcast or multicast the first indication. The terminal device may monitor the first indication in a predefined time instance or event or time window during which the terminal device checks for the first indication. The first indication may include sensing system information or system information. The form or format of the first indication is not limited to the embodiments in the present disclosure.
[0200] Network nodes may not know the exact bandwidth capabilities of unknown terminal devices in a low-power state within a given sensing area. Even if a UE is unable to support the largest SERS bandwidth, it may still support a smaller segment of the bandwidth. Different sensing tasks may require different bandwidths. For example, vehicle ranging accuracy requirements might differ in the longitude and latitude directions. In view of this, in an implementation, a nested structure sensing signal is introduced in the present disclosure. The term “nested structure sensing signal” refers to a hierarchical arrangement of a sensing signal where a reference sensing signal covers an entire bandwidth of the sensing signal, and one or more signal segments share / occupy part or all BW of the reference sensing signal. Each signal segment of the one or more signal segments can be independently detected and measured by a UE. The sensing signal is designed to have plurality of signal segments, and the at least one signal segment on which the sensing measurement is performed is included in the plurality of signal segments. In an implementation, the plurality of signal segments are in the same receiving occasion, each of the plurality of signal segments occupies a corresponding bandwidth and is independently measurable over its corresponding bandwidth.
[0201] The nested structure sensing signal includes a reference sensing signal and plurality of signal segments. The reference sensing signal covers the whole resource elements of the sensing signal. Each of the plurality of signal segments covers part BW of the reference sensing signal. Each of the plurality of signal segments can be detected and measured independently. In an implementation, for each of the plurality of signal segments, a frequency position of the signal segment may be indicated by a frequency offset relative to a reference sensing signal. The plurality of signal segments may be distributed in one or more BW sets, and each BW set of the one or more BW sets is associated with one or more signal segments. The association between each BW set and the one or more signal segments may be one-to-one, one-to-many or many-to-many. A single signal segment may be associated with a single BW set, and a single BW set may include BWs (also referred to as BW segments) of plurality of signal segments, or plurality of signal segments can be distributed across a plurality of BW sets. For example, there are three BW sets, BW set 1, BW set 2, BW set 3, BW set 1 is associated with signal segment 1 and signal segment 2, BW set 2 is associated with signal segment 3, BW set 3 is associated with signal segment 1, signal segment 2, signal segment 3 and signal segment 4, wherein resource elements of signal segment 1 occupy or cover BW1, resource elements of signal segment 2 occupy or cover BW2, resource elements of signal segment 3 occupy or cover BW3 and resource elements of signal segment 4 occupy or cover BW4. The same BW can show up in different BW sets. The association between each BW set and the one or more signal segments can be indicated in the first indication or a sensing response. The resource elements of the sensing segment may include a part or all of the resource elements of the reference sensing signal. The resource elements of the sensing segment may reuse the resource elements of the reference sensing signal.
[0202] The configuration information of the plurality of signal segments may be indicated by the sensing information. The BW of each signal segment can be configured with identification information, e.g., a BW index. Each of the BW sets may be also configured with identification information. Alternatively, the signal segment can also be configured with identification information, e.g., a segment index, and in this case, the BW set can also be referred to as a segment set. The identification information of BW or signal segment can be used for reporting or indicating the sensing results. In an implementation, the BW set indicates the BW of each signal segment, for example, the BW set includes one or more BW indices. The terminal device may match its bandwidth capability to the indicated BW (s) . If plurality of signal segments have the same bandwidth, the terminal device may select the signal segment corresponding to its supporting frequency. The terminal device may perform measurements on the selected signal segment and report the result along with the identification information of the signal segment. In another implementation, the BW set indicates the identification information of the signal segment. In this case, the terminal device can perform sensing measurements on the signal segment corresponding to the indicated identification information, and may probably report the results along with the indicated identification information. When plurality of signal segments are indicated, the terminal device may carry out the sensing measurements using one or more of the plurality of signal segments, and the terminal device may report the results along with the identification information of the used signal segment (s) . To save overhead, the terminal can use an index of the signal segment in the BW set to indicate the segment. For example, if only two signal segments are configured, a single bit can be used to indicate which signal segment is used. Each segment index corresponds to a specific signal segment, which can be predefined or preconfigured by the network.
[0203] FIG. 9 is a schematic diagram of a nested structure sensing signal according to one or more embodiments of the present disclosure. As shown in FIG. 9, a reference sensing signal covers the entire bandwidth of a sensing signal. Resource elements of the sensing signal include resource elements of plurality of signal segments of the sensing signal or the resource elements of the plurality of signal segments reuse the resource elements of the reference signal. For example, the plurality of signal segments include segment 1, segment 2, segment 3, and segment 4. The segment 1 covers segment BW 1, the segment 2 covers segment BW 2, the segment 3 covers segment BW 3 and the segment 4 covers segment BW 4.
[0204] The nested structure allows for flexible allocation of sensing resources, accommodating a wide range of UE capabilities and sensing requirements. By segmenting the sensing signal bandwidth, the network can optimize resource usage and reduce waste, improving overall system performance. The structure supports diverse sensing tasks and can be easily adapted to new requirements or UE capabilities. The resource elements of the sensing segments may reuse the resource elements of the reference sensing signal, and therefore, each sensing segment can be configured based on resource configuration of the reference sensing signal. In this way, independent assignments of different BW resources for sensing segments can be avoided.
[0205] The sensing signal configuration can include time and frequency resources for the reference sensing signal, periodicity and offset, and the starting reference time can be predefined or preconfigured. The network device may broadcast the sensing signal, and the broadcast sensing signal can be reused for terminal devices of different BW capabilities.
[0206] The first qualification requirement may include a plurality of BW sets, e.g., a list of BW sets of the plurality of signal segments. The BW set includes one or more BWs. When the first qualification requirement is met, the terminal device may measure at least one signal segment according to its maximum supporting BW.
[0207] By introducing the nested sensing signal structure, the solution allows for a flexible allocation of sensing signal resources to different terminal devices based on their capabilities. This dynamic resource allocation reduces wastage and enhances overall efficiency of resource assignments. The terminal device can be woken up for sensing measurements if they meet specific qualification requirements, thus reducing unnecessary wake-ups and power usage.
[0208] The first qualification requirement may be a criteria that a terminal device needs to meet, once the first qualification requirement is met, it means the terminal device is qualified for performing sensing measurements. The first qualification requirement may include, but are not limited to, bandwidth capabilities, frequency location (s) or frequency range (s) , signal strength thresholds, or other technical specifications. The frequency location and the frequency range indicate the frequency location of the sensing signal. In an implementation, the first qualification requirement may include at least one of: a target sensing area, a sensing state, a second RSRP or RSRPP threshold for sensing, an idle user equipment (UE) identifier (ID) range, or an SE-RNTI.
[0209] The target sensing area may be a specific geographic area where the terminal device is expected to perform sensing tasks. In some cases, the sensing task may need to be limited to specific regions (e.g., within a city or a particular zone) . The network device can broadcast a target sensing area included in the sensing information. The terminal device may check its current location against the target sensing area, if the terminal device is within the target sensing area, the terminal device can be determined to be qualified. Otherwise, the terminal device is determined to be unqualified.
[0210] The sensing state may refer to a current state of the terminal device related to its sensing capabilities or readiness. The sensing state may also be referred to as “mobility state” . The sensing state may include at least one of: a speed range, a distance range, a position range, an angle value range, a resolution range, an accuracy range. For example, for applications such as vehicle-to-everything (V2X) communication or autonomous driving, the speed of the terminal device may significantly impact the sensing accuracy and requirements. The distance range may be a range of distances relevant to the sensing task, such as the distance to a target object or the distance over which the terminal device can perform sensing. In applications such as radar sensing or proximity detection, the distance to a target object may be required for accurate measurements. The position range may be a range of positions relevant to the sensing task. The angular value range may be a range of angles relevant to the sensing task, such as an angle of arrival (AoA) or a direction of the terminal device relative to a target. The resolution range may be a range of resolutions required for the sensing task, such as the precision or granularity of the measurements. For high-precision sensing tasks such as imaging or high-resolution radar, the resolution of the measurements may need to be considered. The accuracy range may be a range of accuracies required for the sensing task, such as the acceptable error margin in measurements. For applications requiring high accuracy, such as precise positioning or distance measurement, the accuracy of the sensing task may need to be considered.
[0211] The second RSRP or RSRPP threshold for sensing may be a threshold value for reference signal received power (RSRP) or reference signal received path power (RSRPP) that the terminal device needs to meet to perform sensing. The network may require the terminal device to have a certain signal strength to ensure reliable sensing measurements. For example, the terminal device may measure its received signal strength and compare it with the second RSRP or RSRPP threshold for sensing. If the terminal device’s signal strength meets the second RSRP or RSRPP threshold or exceeds the second RSRP or RSRPP threshold, the terminal device may perform the sensing task; otherwise, the terminal device may skip the sensing task. In an implementation, the second RSRP or RSRPP threshold may be a second RSRP or RSRPP threshold of a Synchronization Signal (SS) .
[0212] The idle user equipment (UE) identifier (ID) range may be a range of UE identifiers that are configured to be used by idle UEs when reporting sensing measurements. Idle UE ID can be randomly generated within the configured scope. If the terminal device is a qualified terminal device for the sensing task, the terminal device may perform sensing measurements, and randomly generate an ID within the configured idle UE ID range. The terminal device may report the randomly generated ID together with the sensing measurement result. The network may collect the reported IDs to determine the number of participating idle UEs. If the network determines that the current number of participating UEs is insufficient, it may further wake up additional UEs to meet the sensing task requirements.
[0213] The sensing radio network temporary identifier (SE-RNTI) may be a temporary identifier assigned to UEs for sensing tasks. If the UE has a valid SE-RNTI, it may perform the sensing task; otherwise, it may skip the task.
[0214] Each of these qualification requirements serves a specific purpose in ensuring that the eligible terminal device performs the sensing task. By combining these requirements, the network can efficiently manage sensing operations, optimize resource usage, and ensure reliable and accurate sensing measurements.
[0215] In an implementation, a first one-step sensing measurement report generation method can be adopted. Both overhead and power consumption reduced with one-step sensing measurement report generation procedure. In the first one-step sensing measurement report generation method, the terminal device receives the first indication. The first indication indicates sensing information and a first qualification requirement. The sensing information may indicate configuration information of the plurality of signal segments and a first reporting resource for a first sensing report. The first sensing report may be transmitted in Message A of a two-step random access process. By providing detailed configuration information for plurality of signal segments, the terminal device can obtain the plurality of signal segments accurately. For each of the plurality of signal segments, a frequency position of the signal segment may be indicated by a frequency offset relative to a reference sensing signal. The time position of the signal segment can also be indicated. The terminal device can obtain the plurality of signal segments based on the frequency position of the signal segment or the time-frequency position of the signal segment. When the terminal device determines that the first qualification requirement is not met, the terminal device may not obtain the signal segment or may not perform the sensing measurement. When the first qualification requirement is met, the terminal device may perform sensing measurement on the at least one signal segment according to the configuration information of the plurality of signal segments, BW of the at least one signal segment is supported by the terminal device, so that the terminal device is able to perform sensing measurement on the at least one signal segment.
[0216] After performing the sensing measurement, the terminal device may transmit the first sensing report using the first reporting resource. The first sensing report may include a sensing measurement result based on the at least one signal segment. If one sensing segment is configured and measured, the terminal device can report the sensing measurement result corresponding to said sensing segment in the reporting resource. The first reporting resource may correspond to the first qualification requirement, or the first reporting resource may correspond to a BW on which the sensing measurement is performed. If the first qualification requirement is configured, the first qualification requirement may indicate one or more BWs of signal segments or one or more signal segments with different BWs for sensing measurement. That is, an associated sensing report resource is configured for each signal segment or qualification requirement. In this way, collision probability between the reporting resources can be reduced. The reporting resources can include a preamble and the respective data channel that follows the transmission of the preamble, or can include a bundled preamble and the respective data channel. The data channel may carry the sensing report. The preamble can be used to identify different sensing reports from different UEs. The preamble resource may include time, frequency and code resources, which can be configured by the first indication, e.g., sensing system information or system information. The sensing report resources may correspond to PRACH and PUSCH resources. For example, the preamble can be transmitted in the PRACH, and sensing report data (SRD) or the payload can be carried by the PUSCH. The sensing report resources can also correspond to PRACH or preamble resources, which means the PRACH or the preamble can carry the sensing report information (sensing report) with specific time, frequency and code resources. In an implementation, identification information of the at least one signal segment is transmitted together with the sensing measurement result. Optionally, identification information of the at least one signal segment may be indicated implicitly through the association between the signal segment and the reporting resource.
[0217] For example, the terminal device receives a first indication, and the first indication indicates sensing information and a first qualification requirement. The sensing information may indicate configuration information of the plurality of signal segments and a first reporting resource for a first sensing report. The configuration information includes configuration information of three signal segments, namely segment 1 (corresponding to BW of 20 MHz) , segment 2 (corresponding to BW of 40 MHz) , segment 3 (corresponding to BW of 100 MHz) . The frequency position of the signal segment may be indicated by a frequency offset relative to a reference sensing signal. For example, when the maximum supporting BW of the terminal device is smaller than 20 MHz, the terminal device may skip the reception of the signal segments or the measurement. On the other hand, when the maximum supporting BW is larger than 20 MHz but less than 40 MHz, and the terminal device determines that the device meets the qualification requirement, and the terminal device may perform sensing measurement on signal segment 1, and may transmit a first sensing report to the network device using the first reporting resource. The first sensing report may include a sensing measurement result of each measured signal segment, and the first sensing report may further include identification information of the corresponding measured signal segment. The first reporting resource may be a preamble resource or a data resource. The term “supporting BW” refers to the BW that can be supported by the terminal device.
[0218] The terminal device can perform sensing measurement activation, measurement and report based on one shot broadcast configuration. In this case, both signaling and power consumption are reduced. Signal segment-specific resources may be beneficial for reporting reduction in collision between resources.
[0219] In an implementation, a second one-step sensing measurement report generation method can be adopted. The terminal device receives the first indication, the first indication indicates sensing information and a first qualification requirement. The sensing information may indicate configuration information of the plurality of signal segments, a first reporting resource for a first sensing report, and a first occasion for monitoring a second indication. The second indication indicates a second qualification requirement, and the second qualification requirement is part of the first qualification requirement. The network device may transmit the second indication in the first occasion. When the second qualification requirement is met, the terminal device may perform sensing measurement on the at least one signal segment according to the configuration information of the plurality of signal segments, and transmit the first sensing report using the first reporting resource. The first sensing report may be transmitted in Message A of a two-step random access process. When the second qualification requirement is not met, the terminal device may not obtain the signal segment or may not perform the sensing measurement. The first sensing report includes a sensing measurement result based on the at least one signal segment. For each of the plurality of signal segments, a frequency position of the signal segment may be indicated by a frequency offset relative to a reference sensing signal. The time position of the signal segment can also be indicated. In an implementation, the configuration information of the plurality of signal segments may include a time offset of a second occasion for receiving the sensing signal relative to the first occasion, that is, the receiving occasion of the signal segment can be indicated by the receiving occasion of the second indication. The terminal device can receive the plurality of signal segments based on the frequency position of the signal segment or the time-frequency position of the signal segment. The first indication may configure the nested sensing signal and indicate a first reporting resource for a first sensing report, which are similar to the first one-step sensing measurement report generation method described above. The first indication may further indicate a first occasion for monitoring a second indication. The second indication may be carried in a wake-up signal (WUS) . The WUS may be a low power wake-up signal (LP-WUS) . The terminal device may monitor in the first occasion and receive the second indication in the first occasion according to the first indication. When the second indication is carried in a WUS or a LP-WUS, the terminal device is in a low-power state (or in an ultra-deep sleep mode) when monitoring the first indication, and the main radio (MR) is in a sleep state, thus reducing the power consumption. The second indication indicates second qualification requirement, which is a subset of the first qualification requirement. The second indication may include the second qualification requirement. Alternatively, the first qualification requirement may include a plurality of qualification requirement sets and identification information of each qualification requirement set, and the second qualification requirement can be indicated via identification information of a qualification requirement set. The second indication can provide more specific or updated requirements that the terminal device needs to satisfy to perform the sensing measurement. The second indication can dynamically update the qualification requirements based on real-time network conditions or specific sensing task requirements. The network can adaptively control which terminal devices should perform sensing tasks based on their current signal quality and capabilities. The first reporting resource may be a preamble resource or a data resource. The first reporting resource may correspond to the first qualification requirement, or the first reporting resource may correspond to a BW on which the sensing measurement is performed. In an implementation, identification information of the at least one signal segment is transmitted together with the sensing measurement result.
[0220] In an implementation, after receiving the first indication, the terminal device determines whether the first qualification requirement is met. When the first qualification requirement is met, the terminal device may monitor the second indication in the first occasion. On the other hand, when the first qualification requirement is not met, the terminal device may skip monitoring the second indication in the first occasion. In some cases, the first qualification requirement may indicate a second reference signal received power (RSRP) or reference signal received path power (RSRPP) threshold for sensing. When an RSRP or RSRPP of a synchronization signal (SS) received is not greater than the second RSRP or RSRPP threshold, the terminal device may skip the monitoring of the second indication. When the RSRP or RSRPP of the SS received is greater than the second RSRP or RSRPP threshold, the terminal device may monitor the second indication in the first occasion. The selective monitoring can reduce unnecessary signaling and processing, conserving both the terminal device and network resources.
[0221] In an implementation, the second qualification requirement may indicate one or more BWs, and the one or more BWs belong to one or more BW sets indicated in the first qualification requirement. The network can dynamically allocate different BW sets or signal segment sets to different terminal devices based on their capabilities and the specific sensing requirements. The second indication may include identification information of each of the one or more BW or signal segment sets. The first qualification requirement may indicate a BW or signal segment set list and identification information of each of the BW set in the BW set list, and the second qualification requirement may include identification information of each of the one or more BW sets in the BW set list or the one or more signal segments in the signal segment set list. The BW set may also include identification information of the signal segment (s) , and in this case, the BW set can also be referred to as a segment set. In this way, the indication capacity for the indication of BW sets can be reduced.
[0222] In an implementation, the second qualification requirement may further indicate one or more first reference signal received power (RSRP) or reference signal received path power (RSRPP) thresholds corresponding to the one or more BWs. After the terminal device receives the signal segments, the terminal device may perform sensing measurement on the at least one signal segment, and the terminal device may determine whether the received power of the at least one signal segment is greater than the corresponding RSRP or RSRPP threshold. When an RSRP or RSRPP of the signal segment is not greater than a first RSRP or RSRPP threshold corresponding to at least one of the one or more BWs, the terminal device may determine that the second qualification requirement is not met. In this case, the terminal device may skip performing the sensing measurement and may further skip the transmission of the sensing measurement result. When the RSRP or RSRPP of the signal segment is greater than the first RSRP or RSRPP threshold corresponding to the at least one of the one or more BWs, the terminal device may determine that the second qualification requirement is met, and go on with the sensing measurement and reporting of the sensing measurement result. By specifying RSRP or RSRPP thresholds, the network can ensure that the received sensing measurement result is from the terminal device with sufficient signal quality, and the reliability and accuracy of the sensing measurement can be improved.
[0223] In an implementation, the second qualification requirement may further indicate a reference signal received power (RSRP) or reference signal received path power (RSRPP) threshold for the second indication. When an RSRP or RSRPP of the received second indication is not greater than the RSRP or RSRPP threshold for the second indication, the terminal device may skip the reception of the sensing signal. When the RSRP or RSRPP of the second indication received is greater than the RSRP or RSRPP threshold for the second indication, the terminal device may receive the sensing signal and perform the sensing measurement.
[0224] In an implementation, the second indication may indicate activation or deactivation of the at least one signal segment. The network can deactivate specific signal segments when it wants the terminal device to stop sensing measurements on those segments, potentially to save power or to reallocate resources. The network can activate specific signal segments when it needs the terminal device to perform sensing measurements on those segments. The terminal device does not need to receive a signal segment when the second indication indicates deactivation of the signal segment, even though the BW of the signal segment or the signal segment is within the BW set (s) indicated by the second indication. By deactivating unnecessary signal segments, the network can conserve resources and reduce power consumption by the terminal device. The terminal device can process and measure the active signal segments, reducing the processing overhead and improving overall efficiency.
[0225] Signal segment-specific resources are helpful for reporting resource collision reduction. Terminal device involvement can be limited in sensing report with the qualification set configured by the second indication. The qualification index-specific reporting resource can reduce the reporting resource collision. The UE which does not meet the requirements will stop the PDCCH detection (the detection of the first indication) following the second indication. Since the UE does not have to perform detection unnecessarily in this case, the power consumption can be reduced. Moreover, the qualified terminal device reports sensing results in BW segment-specific resources, and the unqualified terminal device can keep sleeping. The reporting resources are segment-specific configured to avoid reporting resource collision.
[0226] In an implementation, a first three-step sensing measurement report generation method can be adopted. The terminal device receives the first indication. The first indication indicates sensing information and a first qualification requirement. The sensing information may indicate a first reporting resource for a first sensing report. When the first qualification requirement is met, the terminal device may transmit a first sensing report using the first reporting resource, and the network device may receive the first sensing report. The network device may transmit a sensing response after receiving the first sensing report, and the terminal device may receive a sensing response. The sensing response indicates configuration information of the at least one signal segment and a second reporting resource for a second sensing report. In some cases, when the sensing signal adopts a nested structure, the indication of the configuration information of the at least one signal segment can be realized by indicating the configuration information of the plurality of signal segments, so that the terminal device can determine the configuration information of the at least one signal segment based on the sensing response and the BW on which the sensing measurement is performed. In some cases, since the terminal device may report its supporting BW in the first sensing report, the network may assign specific resource particles (e.g., time-frequency resources) for the signal segment corresponding to the reported supporting BW based on the first sensing report, and transmit the configuration information of the signal segment to the terminal device via the sensing response. The terminal device may receive the at least one signal segment and perform sensing measurement on the at least one signal segment, and then transmit the second sensing report using the second reporting resource, where the second sensing report includes a sensing measurement result based on the at least one signal segment. The network device can receive the second sensing report using the second reporting resource. The first sensing report may be transmitted in Message 1 of a four-step random access process. The sensing response may be transmitted in Message 2 of a four-step random access process. The second sensing report may be transmitted in Message 3 of a four-step random access process. In an implementation, the first indication may further indicate an offset between a third occasion for transmitting the first sensing report and a fourth occasion for receiving the sensing response. In this case, the terminal device can monitor and receive the sensing response in the fourth occasion.
[0227] The first qualification requirement may include one or more BW sets. The terminal device may determine whether its maximum supporting BW covers at least one signal segment indicated in the first qualification requirement. When the first qualification requirement is met, the first sensing report may indicate at least one BW segment which is measurable by the terminal device. In this case, if the terminal device can support the BW in the qualification BW set indicated by the first indication, the terminal device can report the identification information of the BW or the signal segment in the BW set indicated by the first indication. Since the terminal device indicates its measurable BW, the network device can configure the sensing signal based on the first sensing report from different terminal devices. In this case, parameters such as signal segment’s configuration (SERS configuration) may not be included compared with the one-step sensing measurement report generation method. Optionally, the network device can set up nested sensing signal with segment bandwidth BW configurations for each sensing signal beam. In an implementation, the sensing response may indicate configuration information of the plurality of signal segments. In an implementation, the configuration information of the at least one signal segment may include a time offset of a second occasion for receiving the plurality of signal segments relative to a fourth occasion for receiving the sensing response. Then the terminal device can receive the at least one signal segment in the second occasion based on the configuration information of the at least one signal segment. There will be a reduced probability that different terminal devices share the same signal segment BW. Alternatively, just dedicated signal segment BWs can be configured for different terminal devices.
[0228] In an implementation, a cyclic redundancy check (CRC) of the sensing response can be scrambled with a sensing radio network temporary identification (SE-RNTI) . The network device may assign a specific RNTI for sensing entity responses. The terminal device can decode the random access response (RAR) using the assigned SER-RNTI. The SE-RNTI is used to scramble the CRC of the sensing response, ensuring that only the terminal device with the correct SE-RNTI can decode the response. After preamble and data transmission, beam-specific SER configuration can be used to avoid undesirable sensing signal beam transmission, thus reducing consumption of both resources and energy.
[0229] In comparison with the one-step sensing measurement report generation method, parameters such as signal segment’s configuration are not included in the first indication. Instead, the signal segment’s configuration can be carried in the sensing response. What’s more, sensing BW (BW on which the terminal device performs sensing measurement) is reported by preamble and data, which allows the network to configure signal segment’s BW in the sensing response signaling that follows. By configuring the signal segments based on the sensing report from the terminal device, the network can avoid assigning bandwidths that the terminal device cannot support or that are inefficient for the terminal device’s capabilities, therefore undesirable sensing signal configurations can be avoided. After preamble and data transmission, beam-specific sensing signal configuration can be used to avoid undesirable sensing signal beam transmission, thus reducing both resources and energy consumption.
[0230] In an implementation, a second three-step sensing measurement report generation method can be adopted. The terminal device receives the first indication. The first indication indicates sensing information and a first qualification requirement. The sensing information indicates a first reporting resource for a first sensing report and a first occasion for monitoring a second indication. The second indication indicates a second qualification requirement, and the second qualification requirement is part of the first qualification requirement. When the second qualification requirement is met, the terminal device transmits a first sensing report using the first reporting resource. The first reporting resource may be a preamble resource or a data resource. The first reporting resource may correspond to the first qualification requirement, or the first reporting resource may correspond to a BW on which the sensing measurement is performed. The network device may receive the first sensing report, and transmit a sensing response. The terminal device may receive the sensing response, where the sensing response indicates configuration information of the at least one signal segment and a second reporting resource for a second sensing report. The terminal device may receive the at least one signal segment based on the configuration information of the at least one signal segment and perform sensing measurement on the at least one signal segment. The terminal device may transmit the second sensing report using the second reporting resource, wherein the second sensing report includes a sensing measurement result based on the at least one signal segment. The network device may receive the second report. The first sensing report may be transmitted in Message 1 of a four-step random access process. The sensing response may be transmitted in Message 2 of a four-step random access process. The second sensing report may be transmitted in Message 3 of a four-step random access process. The second indication may be carried in a wake-up signal (WUS) . The WUS may be a low power wake-up signal (LP-WUS) . When the second indication is carried in a WUS or a LP-WUS, the terminal device is in a low-power state (or in an ultra-deep sleep mode) when monitoring the first indication, and the main radio (MR) is in sleep state thus reducing the power consumption. The second indication indicates second qualification requirement, which is a subset of the first qualification requirement. The second indication may include the second qualification requirement. Alternatively, the first qualification requirement may include a plurality of qualification requirement sets and identification information of each qualification requirement set, and the second qualification requirement can be indicated via identification information of a qualification requirement set. The second indication can provide more specific or updated requirements that the terminal device needs to satisfy to perform the sensing measurement. The second indication can dynamically update the qualification requirements based on real-time network conditions or specific sensing task requirements. The network can adaptively control which terminal devices should perform sensing tasks based on their current signal quality and capabilities. In an implementation, the first indication may further indicate an offset between a third occasion for transmitting the first sensing report and a fourth occasion for receiving the sensing response. In this case, the terminal device can monitor and receive the sensing response in the fourth occasion.
[0231] In an implementation, the network device may transmit the second indication in the first occasion. The terminal device may monitor and receive the second indication in the first occasion. Optionally, when the first qualification requirement is met, the terminal device may monitor the second indication in the first occasion, and may receive the second indication. When the first qualification requirement is not met, the terminal device may skip monitoring the second indication in the first occasion. In an implementation, the first qualification requirement may indicate a second reference signal received power (RSRP) or reference signal received path power (RSRPP) threshold for sensing. When an RSRP or RSRPP of a synchronization signal (SS) received is not greater than the second RSRP or RSRPP threshold, the terminal device may skip the monitoring of the second indication. When the RSRP or RSRPP of the SS received is greater than the second RSRP or RSRPP threshold, the terminal device may monitor the second indication in the first occasion. The selective monitoring can reduce unnecessary signaling and processing, conserving both the terminal device and network resources.
[0232] In an implementation, the second qualification requirement may indicate one or more BWs or signal segments, and the one or more BWs or signal segments belong to one or more BW sets indicated in the first qualification requirement. The network can dynamically allocate different BW sets to different terminal devices based on their capabilities and the specific sensing requirements. The second indication may include identification information of each of the one or more BW sets. The first qualification requirement may indicate a BW set list and identification information of each of the BW set in the BW set list, and the second qualification requirement may include identification information of each of the one or more BW sets in the BW set list. In this way, the indication capacity for the indication of BW sets can be reduced.
[0233] In an implementation, the second qualification requirement may further indicate one or more first reference signal received power (RSRP) or reference signal received path power (RSRPP) thresholds corresponding to the one or more BWs. After the terminal device receives the signal segments, the terminal device may perform sensing measurement on the at least one signal segment, and the terminal device may determine whether the received power of the at least one signal segment is greater than the corresponding RSRP or RSRPP threshold. When an RSRP or RSRPP of the signal segment is not greater than a first RSRP or RSRPP threshold corresponding to at least one of the one or more BWs, the terminal device may determine that the second qualification requirement is not met. In this case, the terminal device may skip performing the sensing measurement and may further skip the transmission of the sensing measurement result. When the RSRP or RSRPP of the signal segment is greater than the first RSRP or RSRPP threshold corresponding to the at least one of the one or more BWs, the terminal device may determine that the second qualification requirement is met, and performs the sensing measurement and reporting of the sensing measurement result. By specifying the RSRP or RSRPP thresholds, the network can ensure that the received sensing measurement result is from the terminal device with sufficient signal quality, and the reliability and accuracy of the sensing measurement can be improved.
[0234] In an implementation, a cyclic redundancy check (CRC) of the sensing response can be scrambled with a sensing radio network temporary identification (SE-RNTI) . The network device may assign a specific RNTI for sensing entity responses. The terminal device can decode the random access response (RAR) using the assigned SE-RNTI. The SE-RNTI is used to scramble the CRC of the sensing response, ensuring that only the terminal device with the correct SE-RNTI can decode the response. After preamble and data transmission, beam-specific SER configuration can be used to avoid undesirable sensing signal beam transmission, thus reducing both resources and energy consumption.
[0235] In comparison with the one-step sensing measurement report generation method, parameters such as the signal segment’s configuration may not be included. The qualification index-specific reporting resource can reduce the reporting resource collision. The UE not meeting the requirements will stop the PDCCH detection following the second indication. Since the UE does not have to perform detection unnecessarily in this case, the power consumption can be reduced. Moreover, the qualified terminal device reports sensing results in BW segment-specific resources, and the unqualified terminal device can continue to remain in the sleep state. The reporting resources are segment-specific configured to avoid collision between reporting resources. Additionally, the sensing BW is reported by the preamble and data which allows the network to configure the signal segment’s BW in the sensing response signaling that follows. By configuring the signal segments based on the sensing report from the terminal device, the network can avoid assigning bandwidths that the terminal device cannot support or that are inefficient for the terminal device’s capabilities, therefore undesirable sensing signal configurations can be avoided. After transmission of the preamble and data, beam-specific sensing signal configuration can be used to avoid undesirable sensing signal beam transmission, thus reducing consumption of both resources and energy.
[0236] The first occasion, the second occasion and the third occasion can also be configured by indicating a period of the occasion and a time offset of the occasion relative to a reference time (e.g., a predefined system frame and slot or the second occasion) .
[0237] FIG. 10 is a schematic flowchart of a method for sensing measurement according to one or more embodiments of the present disclosure. The method shown in FIG. 10 illustrates interaction between a network device and a terminal device. In an example, the terminal device can be referred to as a first device, and the network device can be referred to as a second device. It should be understood that the method shown in FIG. 10 can also be realized by other devices, such as chips or communication devices with communication capabilities. In the following embodiments, the above description related to same or similar terminologies can also apply here, such as the principle of the nested structure sensing signal, the first and second indications, the first and second qualification requirements, or the first and second reporting resources. Some details may be omitted for the sake of brevity. As shown in FIG. 10, the method includes the following steps.
[0238] At S1001, the network device transmits a first indication, and the terminal device receives the first indication. The first indication indicates sensing information and a first qualification requirement, the first qualification requirement is used for determining whether the first device is qualified to perform sensing measurement on a sensing signal based on the sensing information.
[0239] At S1002, the terminal device monitors the second indication, wherein the second indication indicates a second qualification requirement, and the second qualification requirement is part of the first qualification requirement.
[0240] The network device may transmit the second indication in the first occasion. When the second qualification requirement is met, the terminal device may perform sensing measurement on the at least one signal segment according to the configuration information of the plurality of signal segments, and transmit the first sensing report using the first reporting resource. When the second qualification requirement is not met, the terminal device may not obtain the signal segment or may not perform the sensing measurement. The first indication may further indicate a first occasion for monitoring the second indication. The second indication may be carried in a wake-up signal (WUS) . The WUS may be a low power wake-up signal (LP-WUS) . The terminal device may monitor in the first occasion and receive the second indication in the first occasion according to the first indication. When the second indication is carried in a WUS or a LP-WUS, the terminal device is in a low-power state (or in an ultra-deep sleep mode) when monitoring the first indication, and the main radio (MR) is in sleep state thus reducing the power consumption. The second indication indicates second qualification requirement, which is a subset of the first qualification requirement. The second indication may include the second qualification requirement. Alternatively, the first qualification requirement may include a plurality of qualification requirement sets and identification information of each qualification requirement set, and the second qualification requirement can be indicated via identification information of a qualification requirement set. The second indication can provide more specific or updated requirements that the terminal device needs to satisfy to perform the sensing measurement. The second indication can dynamically update the qualification requirements based on real-time network conditions or specific sensing task requirements. The network can adaptively control which terminal devices should perform sensing tasks based on their current signal quality and capabilities. The first reporting resource may be a preamble resource or a data resource.
[0241] In an implementation, the abovementioned nested structure sensing signal can also be used. Resource elements of the sensing signal include resource elements of plurality of signal segments.
[0242] In an implementation, the sensing information indicates configuration information of plurality of signal segments of the sensing signal and a first reporting resource for a first sensing report. When the second indication is detected and the second qualification requirement is met, the terminal device may perform sensing measurement on at least one signal segment of the sensing signal, where the plurality of signal segments include the at least one signal segment. The terminal device may transmit the first sensing report using the first reporting resource, where the first sensing report indicates a sensing measurement result based on the at least one signal segment. The one-step sensing measurement report generation method can be adopted here, for the specific implementation, reference can be made to the second one-step sensing measurement report generation method mentioned described above, which, for the sake of brevity, will not be repeated here.
[0243] In an implementation, the second qualification requirement indicates one or more BWs or signal segments, and the one or more BWs or signal segments belong to one or more BW sets indicated in the first qualification requirement. In an implementation, the second indication includes identification information of each of the one or more BW sets. The nested sensing signal and signal segment can be configured by the network, and the specific implementation is the same as the embodiments mentioned above, which, for the sake of brevity, will not be repeated here.
[0244] In an implementation, the configuration information of the plurality of signal segments includes a time offset of a second occasion for receiving the sensing signal relative to a first occasion for monitoring the second indication.
[0245] In an implementation, the sensing information indicates a first reporting resource for a first sensing report. When the second indication is detected and the second qualification requirement is met, the terminal device may transmit first sensing report using the first reporting resource. The network device may receive the first sensing report, and transmit a sensing response. The terminal device may receive the sensing response, where the sensing response indicates configuration information of at least one signal segment of the sensing signal and a second reporting resource for a second sensing report. In some cases, when the sensing signal adopts a nested structure, the indication of the configuration information of the at least one signal segment can be realized by indicating the configuration information of the plurality of signal segments, so that the terminal device can determine the configuration information of the at least one signal segment based on the sensing response and the BW on which the sensing measurement is performed. The terminal device may receive the at least one signal segment based on the configuration information of the at least one signal segment and perform sensing measurement on the at least one signal segment. The terminal device may transmit the second sensing report using the second reporting resource, where the second sensing report includes a sensing measurement result based on the at least one signal segment. The network device may receive the second report. The three-step sensing measurement report generation method can also be adopted here, and for the specific implementation, reference can be made to the second three-step sensing measurement report generation method mentioned above, which, for the sake of brevity, will not be repeated here.
[0246] In an implementation, the second qualification requirement indicates one or more BWs or signal segments, and the one or more BWs or signal segments belong to one or more BW sets indicated in the first qualification requirement.
[0247] In an implementation, the second indication includes identification information of each of the one or more BW sets.

[0250] In an implementation, the second qualification requirement further indicates one or more first reference signal received power (RSRP) or reference signal received path power (RSRPP) thresholds corresponding to the one or more BWs. When an RSRP or RSRPP of the signal segment is not greater than a first RSRP threshold corresponding to at least one of the one or more BWs, the terminal device may determine that the second qualification requirement is not met. When the RSRP or RSRPP of the signal segment is greater than the first RSRP or RSRPP threshold corresponding to the at least one of the one or more BWs, the terminal device may determine that the second qualification requirement is met.

[0258] For the definitions of similar terms and similar implementations, reference can be made to the related description with reference to FIG. 8 and FIG. 9, which will not be described here for the sake of brevity.
[0259] FIG. 11 is a schematic illustration of a one-step sensing measurement report generation method according to one or more embodiments of the present disclosure. As shown in FIG. 11, sensing system information (SenSI) is taken as an example of the first indication for illustration.
[0260] Step 1) SenSI broadcasts sensing information and a first qualification requirement. Specifically, sensing SI broadcast: {SERS (aspecific example of the sensing signal mentioned above) configuration, sensing qualification requirement typically nested SERS BW set list (aspecific example of the first qualification requirement mentioned above) , offset between SERS and sensing report resources, sensing report resource configuration} . The SERS configuration can include time and frequency resources for reference SERS (aspecific example of the reference sensing signal mentioned above) , periodicity and offset, the starting reference time can be predefined or preconfigured.
[0261] Other configurations including Idle UE ID range would also be possible. Idle UE ID can be randomly generated within the configured scope.
[0262] Step 3) UE meets sensing requirement from SenSI and measures SERS segment according to its maximum supporting BW.
[0263] Step 4) UE reports SERS measurement results and SERS BW segment index (aspecific example of the identification information of BW of a signal segment mentioned above) in SenSI using preamble and data channel. This sensing report shown in FIG. 11 can be a specific example of the aforementioned first sensing report in the one-step sensing measurement report generation method.
[0264] The sensing report resources can correspond to PRACH and PUSCH resources, which means preamble can be transmitted in PRACH, and sensing report data (SRD) or payload can be carried by PUSCH. The sensing report resources can also correspond to PRACH or preamble resources, which means PRACH or preamble can carry the sensing report information with specific time, frequency and code resources.
[0265] FIG. 12 is a schematic illustration of a method for sensing measurement according to one or more embodiments of the present disclosure. As shown in FIG. 12, sensing system information (SenSI) is taken as an example of the first indication, a LP-WUS is taken as an example of the second indication for illustration.
[0266] Step 1) SenSI broadcasts sensing information and a first qualification requirement. Specifically, the sensing SI broadcast: {SERS (aspecific example of the sensing signal mentioned above) configuration, sensing qualification requirement typically nested SERS BW set list, LP-WUS monitoring occasions for activating / deactivating SERS transmission, offset between SERS and LP-WUS, offset between SERS and sensing report resources, sensing report resource configuration} . LP-WUS monitoring occasions are the specific example of the first occasions mentioned above. The occasion for receiving the sensing signal is the second occasion mentioned above. The offset between SERS and LP-WUS is a specific example of the time offset of a second occasion for receiving the sensing signal relative to a first occasion for monitoring the second indication mentioned above. The occasion for transmitting the sensing report is a specific example of the third occasion mentioned above.
[0267] For the sensing information configuration, it can be system information configuration, groupcast configuration or multicast configuration.
[0268] Other possible qualification requirements would also be possible, such as target sensing location area, mobility state (e.g., speed range) , or distance / position / angle value / resolution / accuracy range.
[0269] Other possible sensing SI would be SERS beam ID (beam for transmission of SERS) , target sensing area, RSRP threshold for sensing, the SS or CSIRS in QCL with SERS, bistatic sensing mode, monostatic sensing mode. In the bistatic sensing mode, one node transmits the sensing signal, and another node receives the sensing signal. In the monostatic sensing mode, the node transmits the sensing signal and also receives the reflected sensing signal.
[0270] The SERS configuration can include time and frequency resources for reference SERS, periodicity and offset, the starting reference time can be predefined or preconfigured.
[0271] The sensing report resources can correspond to PRACH and PUSCH resources, which means preamble can be transmitted in PRACH, and sensing report data (SRD) or payload can be carried by PUSCH. The sensing report resources can also correspond to PRACH or preamble resources, which means PRACH or preamble can carry the sensing report information with specific time, frequency and code resources.
[0272] Step 2) UE detects LP-WUS which indicates a second qualification requirement, and the second qualification requirement is part of the first qualification requirement. Specifically, the LP-WUS indicates the activated SERS configuration (e.g. SERS configuration index) and the corresponding sensing qualification BW requirement. A qualification BW set with segment BW index is indicated. The SERS BW segment index within the set is predefined / preconfigured. Alternatively, a qualification requirement set (aspecific example of the second qualification requirement mentioned above) is indicated by LP-WUS which includes the BW set requirement. And the qualification index within the set are predefined / preconfigured.
[0273] Step 3) UE meets LP-WUS indicated sensing requirement (aspecific example of the first qualification requirement mentioned above) will measure SERS BW segment according to its maximum supporting BW and sensing SI requirement.
[0274] Step 4) UE reports SERS measurement result and SERS BW segment index or qualification index in LP-WUS using PRACH resources.
[0275] FIG. 13 is a schematic illustration of sensing report resources for nested SERS measurement according to one or more embodiments of the present disclosure. The sensing reporting resources can be SERS segment or qualification requirement specific configuration. If qualification requirement is configured, it includes SERS segment’s BW requirement. That is, an associated sensing report resource is configured for each SERS segment or qualification requirement. Then if one SERS segment is configured and measured, the corresponding UE can report the sensing measurement results in the SERS segment-specific reporting resources. For example, as shown in FIG. 13, the plurality of signal segments include segment 1 covering segment BW 1, segment 2 covering segment BW 2 and segment 3 covering segment BW 3. The sensing report resources can be selected from a segment BW specific PRCH resource pool. In this way, the reporting resource collision probability can be reduced. The reporting resources can be a preamble and the respective data channel that follows the transmission of the preamble, or it can also be bundled preamble and data channel. The data channel carries the sensing report. The preamble can be used to identify different sensing reports from different UEs. The preamble resource includes time, frequency and code resources, which can be configured by the sensing system information or system information.
[0276] The sensing measurement result for reporting may include one or more of position, range, angle, velocity, phase with the required accuracy / resolution, the SERS BW segment ID, beam ID, RSRP (only above threshold) , which is not limited in the embodiments of the present disclosure.
[0277] FIG. 14 is a schematic illustration of a three-step sensing measurement report generation method according to one or more embodiments of the present disclosure. As shown in FIG. 14, sensing system information (SenSI) is taken as an example of the first indication for illustration.
[0278] SenSI broadcasts sensing information and a first qualification requirement. Specifically, SenSI broadcast sensing conditions for sensing preamble transmission and preamble resource configuration, which may include one or more of following items: SS signal strength threshold for sensing idle state or inactive state UE’s preamble transmission, target sensing location area, mobility state (e.g., speed range) , UE supporting maximum BW range, BW aggregation range, or distance / position / angle resolution / accuracy range.
[0279] Step 1: UE meeting sensing SI conditions can transmit the preamble. The UE can be idle state UE or inactive UE or a low power UE. Alternatively, the UE can piggy back its maximum supporting BW with preamble. The preamble can be accompanied by sensing BW which is to be measured by the UE. The preamble can be a specific example of the aforementioned first sensing report in three-step sensing measurement report generation method.
[0280] Step 2.1 &2.2: SER configures nested SERS, PUSCH time offset relative to DL SERS, sensing report resources, report information for the identified candidate UEs. UE with same SER-RNTI can decode RSR RAR response and measure segment SERS according to its BW capability. The sensing report response can be a specific example of the aforementioned sensing response in the three-step sensing measurement report generation method.
[0281] SERS can be nested SERS with segment BW configuration for each SERS beam.
[0282] Step 3: The qualified UE generates the sensing report based on the configurations in step 2. This sensing report can be a specific example of the aforementioned second sensing report in the three-step sensing measurement report generation method.
[0283] The sensing report information is similar to the aforementioned embodiments, and for the sake of brevity, will not be repeated.
[0284] FIG. 15 is a schematic illustration of a method for sensing measurement according to one or more embodiments of the present disclosure. As shown in FIG. 15, sensing system information (SenSI) is taken as an example of the first indication, a LP-WUS is taken as an example of the second indication for illustration.
[0285] Step 1: Sensing SI may broadcast: {sensing qualification requirement typically BW set list, SS signal strength threshold, LP-WUS monitoring occasions, offset between LP-WUS and sensing report resources, sensing report resource configuration} . LP-WUS monitoring occasions are the specific example of the first occasions mentioned above. The occasion for receiving the sensing signal is the second occasion mentioned above. The offset between SERS and LP-WUS is a specific example of the time offset of a second occasion for receiving the sensing signal relative to a first occasion for monitoring the second indication mentioned above. The occasion for transmitting the sensing report is a specific example of the third occasion mentioned above.
[0286] The sensing qualification requirement information includes the bandwidth set list. Each BW set can include multiple BWs or signal segments, each having a predefined index within the set. The BW or the signal segment is used by the UE to determine whether its maximum supporting BW is equal to or larger than this requirement. If it meets the requirement and the received signal strength is above the given threshold, then the UE is a qualified UE and can proceed with the following LP-WUS detection / monitoring.
[0287] On signal strength threshold, in this embodiment, before the first sensing report (preamble &data) transmission, received SS signal strength is used to compare to the given threshold.
[0288] Other qualification requirements are similar as the embodiment shown in FIG. 12.
[0289] Step 2: LP-WUS indicates sensing qualification BW set including Rx signal strength threshold. Alternatively, it can be a qualification requirement set including other qualification requirements (refer to the embodiment shown in FIG. 12) .
[0290] Step 3: UE meeting requirements from LP-WUS can transmit a sensing report in the sensing message which includes a preamble and a data channel. If the UE can support the BW in the qualification BW set indicated by the LP-WUS, the UE can report the BW index in the BW set indicated by the LP-WUS. Alternatively, qualification index in the qualification set indicated by the LP-WUS can be reported.
[0291] Step 4: Sensing response (SER) in FIG. 15 configures one or more of DL SERS resources, sensing report resources including time offset relative to DL SERS, report information. SE-RNTI can be used for sensing response DCI CRC scrambling. UE with the same SE-RNTI can decode the sensing response and measure segment SERS according to its BW capability.
[0292] As the UE already indicates its BW in step 1, there will be a reduced probability that different UEs share the same SERS BW. However, in order to reduce measurement report collision in step 3, the SERS can still be configured as nested SERS. Alternatively, just a dedicated SERS can be configured.
[0293] Step 5: qualified UE detects its configured SERS, makes measurements and reports sensing results.
[0294] As described above, in some cases, sensing SI configures {sensing qualification requirement, LP-WUS, SERS, sensing report resources} parameters for one-step sensing measurement report generation method. Both overhead and power consumption can be reduced with one-step sensing measurement report generation procedure.
[0295] In some cases, nested SERS RE can be used. The nested SERS RE consists of one reference SERS RE and one or more segment SERS REs. The segment SERS REs are part BW of reference SERS REs. Reference SERS REs cover the whole SERS BW REs. An SERS set list can be configured with multiple SERS segments within each set. Nested SERS structure is introduced for efficient SERS transmission. The resource elements of the sensing segments may reuse the resource elements of the reference sensing signal, and therefore, each sensing segment can be configured based on resource configuration of the reference sensing signal. In this way, independent assignments of different BW resources for sensing segments can be avoided.
[0296] In some cases, the sensing SI broadcasts one or more of the following: sensing qualification requirement which includes SERS BW set list or qualification requirement list, signal strength threshold per SERS segment, required value range, accuracy and resolution of position, range, angle, velocity, SERS configurations including SERS segment resources, LP-WUS monitoring occasions for activating / deactivating SERS transmission, offset between SERS and LP-WUS, offset between SERS and sensing report resources, report resource configurations for sensing report. The sensing report resources can be per SERS segment configured. One shot broadcast configuration is proposed for sensing measurement activation, measurement and report. Both signaling and power consumption are reduced. SERS segment-specific resources are helpful for reporting resource collision reduction.
[0297] In some cases, UE detects LP-WUS which indicates the activated SERS configuration, the sensing qualification and sensing report resources. A qualification BW set or qualification requirement set is indicated by the LP-WUS. The SERS BW segment index or qualification index within the set are predefined / preconfigured. The qualification index specific reporting resources can also be indicated. Limited UE can be involved in sensing report with the qualification set configured by the LP-WUS. The qualification index-specific reporting resource can reduce collision between the reporting resources. The UE, which does not meet the requirements, will stop the PDCCH detection following the LP-WUS. Since the UE does not have to perform detection unnecessarily in this case, the power consumption can be reduced.
[0298] In some cases, UE meeting qualification requirements from LP-WUS or sensing SI performs sensing measurement, and report sensing information including one or more of elements from the following set: {Position, range, angle, velocity, phase and the obtained accuracy / resolution, the SERS BW segment ID, beam ID, RSRP} , the report can be carried in the reporting resources which can be BW segment specific resources. Qualified UE will report sensing results in BW segment-specific resources. Unqualified UE can keep sleeping. The reporting resources are segment-specific configured to avoid reporting resource collision.
[0299] In some cases, the sensing SI configures {sensing qualification requirement, LP-WUS, PRACH} parameters for the three-step sensing measurement report generation method. In comparison with the one-step sensing measurement report generation method, parameters such as the SERS configuration may not be included.
[0300] In some cases, sensing qualification requirement can be without SERS configurations. Parameters such as SERS configuration may not be included.
[0301] In some cases, UE reports its max BW by BW index or qualification index from LP-WUS indicated BW set using sensing report resources (preamble + data) . Sensing BW is reported by preamble + data, which allows the network to configure SERS BW in the sensing response signaling that follows, undesirable SERS configurations are avoided.
[0302] In some cases, SER configures SERS resources. Alternatively, the SERS can be a nested SERS. Sensing RNTI can be used for SER CRC scrambling. After preamble and data transmission, beam-specific SER configuration can be used to avoid undesirable SERS beam transmission, thus reducing consumption of both resources and energy.
