METHOD AND RELATED APPARATUSES FOR SENSING ACTIVATION OR DEACTIVATIONTECHNICAL FIELD
[0001] The present disclosure relates to the field of communication technologies, and in particular, to a method and related apparatuses for sensing activation or deactivation.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 includes: monitoring a first indication in a first occasion, where the first indication indicates either activation or deactivation of transmission and / or reception of one or more sensing signals in one or more corresponding second occasions.
[0006] By configuring the terminal device to dynamically activate or deactivate the transmission and / or reception of sensing signal (s) via the first indication, the system achieves flexibility in managing sensing operations, which can enable the terminal device to adapt to varying sensing requirements and conditions without being constrained by fixed configurations. For instance, if sensing is not needed at a particular time, the terminal device can be informed of deactivating the transmission and / or reception of relevant signals based on the first indication, thus conserving resources and reducing interference. Moreover, the system can activate the transmission and / or reception of sensing signals only when necessary and in appropriate occasions. The dynamic signaling configuration can reduce power consumption and signaling overhead may be reduced.
[0007] In an implementation of the first aspect, one or more sets of configurations are configured, and each of the one or more sets of configurations indicates one or more of: the first occasion; the second occasion; a reporting resource for reporting a result of a sensing related measurement based on the sensing signal. By providing multiple sets of configurations that indicate specific occasions and reporting resources, the terminal device can dynamically adjust its sensing activities. This leads to improvement in resource allocation, reduction of unnecessary processing, and enhancement of overall system performance.
[0008] In an implementation of the first aspect, the reporting resource is indicated by a time offset between the second occasion and the reporting resource, or the reporting resource is indicated by a time offset between the first occasion and the reporting resource. The reporting resource may indicate a specific communication channel or a resource that the device should use to report the result of the sensing-related measurement back to the network or other relevant entities. Designating a specific reporting resource can ensure that the sensing measurement results are transmitted efficiently and reliably.
[0009] In an implementation of the first aspect, when the first indication indicates the activation of the sensing signal in the corresponding second occasion, the terminal device may receive the sensing signal in the second occasion. By utilizing the first indication to activate the sensing signal in the corresponding second occasion, the terminal device can accurately receive the sensing signal, leading to more precise sensing measurements.
[0010] In an implementation of the first aspect, the terminal device may report a result of a sensing related measurement based on the sensing signal using the reporting resource.
[0011] In an implementation of the first aspect, the sensing signal is a downlink sensing signal or a sidelink sensing signal.
[0012] In an implementation of the first aspect, one or more sets of configurations are configured, and each of the one or more sets of configurations indicates one or more of: the first occasion, and the second occasion. By providing multiple sets of configurations that indicate specific occasions and reporting resources, the terminal device can dynamically adjust its sensing activities. This leads to improvement in resource allocation, reduction of unnecessary processing, and enhancement of overall system performance.
[0013] In an implementation of the first aspect, when the first indication indicates the activation of the sensing signal in the corresponding second occasion, the terminal device may transmit the sensing signal in the second occasion. By utilizing the first indication to activate the sensing signal in the corresponding second occasion, the terminal device can accurately transmit the sensing signal, leading to more precise sensing measurements.
[0014] In an implementation of the first aspect, the sensing signal is an uplink sensing signal or a sidelink sensing signal.
[0015] In an implementation of the first aspect, when the sets of configurations are configured, the first indication further indicates at least one of the sets of configurations. The first indication indicates which set of configurations are to be applied to the sensing signal that follows the first indication, thereby allowing the terminal device to correctly interpret the sensing signal.
[0016] In an implementation of the first aspect, the one or more sets of configurations are configured via higher layer signaling. This pre-configuration simplifies the system operation and reduces the complexity of signaling. By pre-configuring the sets of configurations, the system can eliminate the need for additional signaling to indicate the configurations during operation. This reduces signaling overhead and facilitates a more efficient communication.
[0017] In an implementation of the first aspect, the higher layer signaling includes at least one of radio resource control (RRC) signaling, media access control control element (MAC CE) signaling, or long term evolution positioning protocol (LPP) signaling.
[0018] In an implementation of the first aspect, the first occasion is indicated by a period of the first indication and a time offset between the first occasion and a reference time.
[0019] In an implementation of the first aspect, the corresponding second occasion is indicated by a time offset between the first occasion and the second occasion.
[0020] In an implementation of the first aspect, the first occasion is configured to be specific to a first device which monitors the first indication. By configuring the first occasion specifically for a particular device, the monitoring schedule can be tailored to match the device’s unique requirements, capabilities, and usage patterns.
[0021] In an implementation of the first aspect, when the first indication indicates deactivation of the one or more sensing signals, the terminal device may skip transmission and / or reception of the one or more sensing signals. By allowing the device to skip transmission and / or reception of sensing signals when they are deactivated, the device conserves energy, and reduces unnecessary processing, thus improving the overall system performance and battery life.
[0022] In an implementation of the first aspect, the first indication further indicates whether a type of each of the one or more sensing signals is a downlink sensing signal, an uplink sensing signal, or a sidelink sensing signal.
[0023] In an implementation of the first aspect, at least one of a starting time of the one or more corresponding second occasions, a period of the one or more corresponding second occasions or a time offset of the one or more corresponding second occasions relative to a reference time is configured.
[0024] In an implementation of the first aspect, the one or more sensing signals are used for one or more sensing related measurements.
[0025] In an implementation of the first aspect, the one or more sensing related measurements include at least one of: one or more downlink sensing measurements, one or more uplink sensing measurements, or one or more sidelink sensing measurements.
[0026] In an implementation of the first aspect, the first indication is carried in a wake-up signal (WUS) or downlink control information (DCI) or a medium access control control element (MAC CE) . When the first 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 the sleep state, thus reducing the power consumption. When the first indication is carried in a DCI or a MAC CE, the terminal device wakes up when monitoring the first indication, and the MR of the terminal device is activated.

[0030] In an implementation of the second aspect, when the first indication indicates the activation of the sensing signal in the corresponding second occasion, the network device may transmit the sensing signal in the second occasion.
[0031] In an implementation of the second aspect, the network device may receive the result of the sensing related measurement based on the sensing signal over the reporting resource.

[0076] 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.
[0077] Examples of wireless communication systems and devices are described below.
[0078] 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 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.
[0079] 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.
[0080] 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.
[0081] 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.
[0082] 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.
[0083] 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)) .
[0084] 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.
[0085] 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.
[0086] 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.
[0087] 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.
[0088] 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) .
[0089] 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.
[0090] 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) .
[0091] 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) .
[0092] 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.
[0093] 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.

[0098] 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.

As a communication interface, the interface circuit 412 is configured to implement communication with another component.

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.
[0102] 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.

A function of the communication unit 513 may be implemented by an interface circuit or a data transceiver circuit on the foregoing chip.
[0106] 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.
[0107] In an example, a functional unit in any one of the foregoing apparatuses may be configured as one or more integrated circuits for implementing the foregoing methods, for example, one or more application-specific integrated circuits (ASICs) , one or more central processing units (CPUs) , one or more microprocessors (microcontroller units, MCUs) , one or more digital signal processors (DSP) , one or more field programmable gate arrays (FPGAs) , or a combination of at least two of these integrated circuit forms.
[0108] In an example, the storage unit 514 may include a random access memory, a flash memory, a read-only memory, a programmable read-only memory, an electrically erasable programmable memory, and / or a register.
[0109] A processor, a processor system, an application processor, a baseband processor, a processor circuit, or a processor core may be collectively referred to as a processor. The processor may include one or a combination of a central processing unit (CPU) , a digital signal processor (DSP) , a microprocessor (microprocessor unit, MPU) , a microcontroller (microcontroller unit, MCU) , a graphics processing unit (GPU) , a field programmable gate array (FPGA) , an artificial intelligence processor (AI processor) , or a neural network processing unit (NPU) .
[0110] The memory may include one or more of the following storage media: a random access memory (RAM) , a static random access memory (static RAM, SRAM) , a dynamic random access memory (dynamic RAM, DRAM) , a phase-change memory (PCM) , a resistive random access memory (resistive RAM, ReRAM) , a magnetoresistive random access memory (magnetoresistive RAM, MRAM) , a ferroelectric random access memory (ferroelectric RAM, FRAM) , a cache, a register, a read-only memory (ROM) , a flash memory, an erasable programmable read-only memory (erasable programmable ROM, EPROM) , a hard disk, and the like. In an example, the computer program instructions used to execute the foregoing embodiments may be stored in a non-volatile memory, for example, at least a part of the memory (for example, one or more of a ROM, a flash memory, an EPROM, or a hard disk) . When the terminal runs, a part or all of corresponding computer program instructions may be loaded to a memory that has a higher transmission speed with the processor, for example, at least a part of the memory 208 and / or the memory 258 (for example, one or more of a RAM, an SRAM, a DRAM, a PCM, a RERAM, an MRAM, a FRAM, a cache, or a register) , so that the processor executes the computer program instructions to perform the steps in the foregoing method embodiments.
[0111] 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.
[0112] In Release 17 (R17) version of 5G, to save energy for UE in radio resource control RRC idle / inactive states, PEI WUS based on DCI format 2-7 was introduced. The UE monitors a physical downlink control channel (PDCCH) before a time offset of a paging occasion (PO) , and the downlink control information (DCI) also indicates the subgroup for each PO.
[0113] In Release 18 / 19 (R18 / 19) versions of 5G, support for new WUS (wake-up signal) and WUR (wake-up receiver) was added. R18 / 19 supports new WUS and WUR. In idle / inactive state, WUS is received before an offset time of PO to decide whether to monitor PDCCH in the following PO. In connected state, WUS before an offset time of DRX (discontinuous reception) on duration to decide whether monitor PDCCH in the DRX on duration.
[0114] 5G also supports UE positioning. The reference signal for UE positioning may include downlink positioning reference signal (DL PRS) and uplink sounding reference signal (UL SRS) . 5G supports periodic DL PRS transmission, supports periodic, semi-persistent and aperiodic UL SRS transmission for positioning.
[0115] However, in 5G power saving modes, sensing capabilities are not considered. There is no clear approach to support sensing within the power-saving procedures of 5G networks. In terms of reference signals (RS) , unlike the uplink SRS, the 5G downlink PRS only supports periodic transmission and reporting, and does not support semi-persistent and aperiodic transmission. The lack of flexibility in both cases may potentially lead to a waste of resources.
[0116] In view of the above, the present disclosure provides a communication method, in which a first indication is used to indicate either activation or deactivation of transmission and / or reception of one or more sensing signals in one or more corresponding second occasions. By configuring the terminal device to dynamically activate or deactivate the transmission and / or reception of sensing signal (s) via the first indication, the system gains flexibility in managing sensing operations, which can enable the terminal device to adapt to varying sensing requirements and conditions without being constrained by fixed configurations.
[0117] Solutions provided by embodiments of the present disclosure can be applied to a communication system including a sensing device. The term “sensing device” refers to 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 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 may receive a signal transmitted by the other device, and can determine attribute information of a target to be sensed by performing measurements on the received signal. Alternatively, the sensing device can forward a measurement result of the echo signal to a further device, and 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, but not limited to, speed, distance, attitude, shape, size, and position of the target. The sensing signal, which is used to sense the target to be sensed, is also known as a detection signal, a radar signal, a radar sensing signal, a radar detection signal, an environmental sensing signal, a reference signal, etc. 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 a SS.
[0118] The embodiments of the present disclosure can be applied to sensing of 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, this application example can be applied to air traffic detection, meteorological detection, safety detection, electromagnetic imaging, etc. This application example is not limited to sensing application scenarios.
[0119] An exemplary scenario of the present disclosure will be described in the first place before detailing the solution of the present disclosure. It should be noted that FIG. 6 illustrates an exemplary scenario to which the solution proposed by the present disclosure may be applied, and should not be construed as a limitation.
[0120] 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 (UE) . The number of network devices and UEs 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 sensing task management, sensing resource allocation, and for sensing results calculation. The configuration of the sensing entity can be directed by the CN, the RAN, or both. Sensing 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 LTE Positioning Protocol (LPP) . The sensing information may include information about techniques that can be used 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 sensing information can occur over a sidelink connection. The communication between the UE and the CN node can be implemented via new radio (NR) positioning protocol ‘a’ (NRPPa) .
[0121] The transmission of sensing information between the base station and the UE is done over a Uu link (the direct radio link between the UE and the base station) . If sensing is configured by the CN, it is transmitted to the RAN node, which then communicates with the UE.
[0122] As shown in FIG. 6 and FIG. 7, an object is to be sensed. The object could be the 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, diffracted or scattered signals 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 then generates a sensing report that includes these attributes and transmits the report to the base station.
[0123] Specific embodiments of the present disclosure will be elaborated in the following description.
[0124] The method provided in embodiments of the present disclosure can be executed by a first device and a second device, where 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.
[0125] 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 among one network device and multiple terminal devices. When involving multiple terminal devices, each of these terminal devices may follow the same process flow to participate in the same sensing task, or may take different actions to complete different sensing tasks.
[0126] 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.
[0127] FIG. 8 is a schematic flowchart of a method according to one or more embodiments of the present disclosure. The method shown in FIG. 8 is implemented by a terminal 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:
[0128] At S801, the terminal device monitors a first indication in a first occasion, where the first indication indicates either activation or deactivation of transmission and / or reception of one or more sensing signals in one or more corresponding second occasions.
[0129] In an implementation, the terminal device monitors in a first occasion (predefined time instance, event or time window) during which the terminal device checks for the first indication. The first occasion is configured by the network for power saving and sensing operations. The first indication may be a signal (e.g., a wake-up signal) or a message (a downlink control message carrying downlink control information) . The form of the first indication is not limited to the embodiments of the present disclosure.
[0130] In an implementation, the one or more sensing signals may be used for performing one or more sensing related measurements. In an implementation, the sensing signal can be a downlink sensing signal, an uplink sensing signal or a sidelink sensing signal. For example, the downlink sensing signal can be a downlink (DL) sensing reference signal (SERS) . The network device transmits the downlink SERS to the terminal device. The terminal device performs sensing related measurement (s) which may be downlink sensing measurement (s) and reports a measurement result to the network device. In another example, the uplink sensing signal can be an uplink (UL) SERS, the terminal device transmits the uplink SERS to the network device. The network device performs sensing related measurement (s) which may be uplink sensing measurement (s) to derive information about the terminal device. In another example, the sidelink sensing signal can be a sidelink (SL) SERS. A further device (e.g., another terminal device) transmits the sidelink SERS to the terminal device. The terminal device performs sensing related measurement (s) which may be sidelink sensing measurement (s) ; alternatively, the terminal device transmits the sidelink SERS to a further device. The further device performs sensing related measurement (s) which may be sidelink sensing measurement (s) .
[0131] In an implementation, the terminal device may be configured with information to locate the first occasion, so as to ensure the monitoring of the first indication. For example, the information may be a starting time of the first occasion or a first time offset of the first occasion relative to a reference time (e.g., a predefined system frame and slot) . Sometimes multiple first occasions may appear periodically, a period of the multiple first occasions may also be configured in advance (e.g., via higher layer signaling) , the terminal device may perform the monitoring in each of the multiple first occasions.
[0132] In an implementation, the terminal device may be also configured with information to locate the one or multiple second occasions, so as to ensure that the terminal device can correctly identify which occasion the first indication is referring to.For example, the information may be a starting time of the one or multiple second occasions or a time offset of the one or multiple second occasions relative to a reference time (e.g., a predefined system frame and slot or the first occasion) . Sometimes multiple second occasions may appear periodically, a period of the multiple second occasions may also be configured in advance (e.g., via higher layer signaling) . In another example, the information may also be indicated by the first indication.
[0133] In an implementation, the second occasion can also be referred to as a sensing occasion.
[0134] The first indication can indicate either activation or deactivation of transmission and / or reception of one or more sensing signals in one or more corresponding second occasions.
[0135] In an implementation, the first indication can indicate activation or deactivation of transmission of one or more sensing signals. For example, the sensing signal may be an uplink sensing signal, and the first indication informs the terminal device to activate or deactivate transmission of the one or more sensing signals in one or more corresponding second occasions. The first indication may correspond to one sensing signal, in which case, the activation or deactivation may be effective for this sensing signal. The first indication may also correspond to multiple sensing signals, in which case, the activation or deactivation may be effective for the multiple sensing signals. For example, the multiple sensing signals may be periodic, in which case a single indication can realize the activation or deactivation of the transmission of the multiple sensing signals.
[0136] In an implementation, the first indication can indicate activation or deactivation of reception of one or more sensing signals. For example, the sensing signal may be a downlink sensing signal, and the first indication informs the terminal device to activate or deactivate reception of the one or more sensing signals in one or more corresponding second occasions. The first indication may correspond to one sensing signal, in which case, the activation or deactivation may be effective for this sensing signal. The first indication may also correspond to multiple sensing signals, in which case the activation or deactivation may be effective for the multiple sensing signals. For example, the multiple sensing signals may be periodic, in which case a single indication can realize the activation or deactivation of the reception of the multiple sensing signals.
[0137] In an implementation, the first indication can indicate activation or deactivation of transmission and reception of one sensing signal. For example, in a self-sensing scenario, the terminal device may transmit a signal and receive an echo signal, the transmitted signal and the echo signal could be the sensing signal, so the first indication informs the terminal device to activate or deactivate transmission and reception of such sensing signal in its corresponding second occasion.
[0138] In an implementation, the first indication can indicate activation or deactivation of transmission and reception of multiple sensing signals. For example, the multiple sensing signals may include a group of periodic uplink sensing signals and a group of periodic downlink sensing signals, so the first indication may inform the terminal device to activate or deactivate the transmission and reception of the multiple sensing signals in their corresponding second occasions.
[0139] In an implementation, the indication of the activation or deactivation can be done in various ways.
[0140] For example, if the first indication is detected in the first occasion, it indicates that it is activation. On the other hand, if the first indication is not detected, it is implied that it is deactivation.
[0141] In another example, the content of the first indication indicates the activation, therefore, upon detecting the first indication, the terminal device determines whether it is either activation or deactivation based on the detected first indication. For example, the first indication may be implemented as a sequence, in which case different states / locations of the first indication represent the activation or deactivation. In another example, the first indication may be implemented as downlink control information, in which case different bit states of the first indication represent the activation or deactivation. The first indication may carry information for indicating either activation or deactivation of transmission and / or reception of one or more sensing signals in one or more corresponding second occasions.
[0142] In an implementation, when the first indication indicates activation of transmission or reception of at least one sensing signal in the corresponding second occasion, the terminal device may receive or transmit the at least one sensing signal according to the first indication. When the first indication indicates deactivation of transmission and / or reception of the one or more sensing signals, the terminal device may skip transmission and / or reception of the one or more sensing signals.
[0143] By configuring the terminal device to dynamically activate or deactivate the transmission and / or reception of sensing signals via the first indication, the system gains flexibility in managing sensing operations, which can enable the terminal device to adapt to varying sensing requirements and conditions without being constrained by fixed configurations. For instance, if sensing is not needed at a particular time, the terminal device can be informed of deactivating the transmission and / or reception of relevant signals based on the first indication, thus conserving resources and reducing interference. Moreover, the system can activate the transmission and / or reception of sensing signals only when necessary and in appropriate occasions.
[0144] In an implementation, the first indication can be carried in a wake-up signal (WUS) or downlink control information (DCI) or a medium access control element (MAC CE) . The WUS can be a low power wake-up signal (LP-WUS) . When the first 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. When the first indication is carried in a DCI or a MAC CE, the terminal device wakes up when monitoring the first indication, and the MR of the terminal device is activated. Optionally, a WUS or LP-WUS can be used to wake up the terminal device before the terminal device monitors the DCI for power saving.
[0145] In an implementation, when the number of sets of configurations is more than one, each of the multiple sets of configurations can be associated with a configuration (CF) identification (ID) . For example, a configuration list and corresponding CF IDs are configured. In an implementation, the one or more sets of configurations can be configured via higher layer signaling. The higher layer signaling includes at least one of radio resource control (RRC) signaling, media access control element (MAC CE) signaling, or long term evolution positioning protocol (LPP) signaling or the signaling between sensing entity in the core network and the UE. By preconfiguring the configuration sets using the higher layer signaling, dynamic indication with overhead or payload of dynamic indication can be reduced and power consumption can be reduced.
[0146] In an implementation, when the sets of configurations are configured, the first indication further indicates at least one of the sets of configurations. For example, a configuration list and corresponding CF IDs are configured and the first indication may further indicate at least one of the sets of configurations in the configuration list via at least one corresponding CF ID. The first indication may indicate which CF (s) will be applied to the sensing signal that follows the first indication.
[0147] In an implementation, the first occasion can be indicated by a period of the first indication and a time offset between the first occasion and a reference time. The reference time may be the occasion of a synchronization signal block (SSB) transmission, a system frame number (SFN) , or a subframe number or a slot number. The first occasion may be configured to be specific to a first device which monitors the first indication (the aforementioned terminal device) , or the first occasion may be dedicated to the terminal device, or the first indication may be UE-specific. By configuring the first occasion specifically for a particular device, the monitoring schedule can be tailored to match the device’s unique requirements, capabilities, and usage patterns.
[0148] In an implementation, the first indication may further indicate whether a type of each of the one or more sensing signals is a downlink sensing signal, an uplink sensing signal, or a sidelink sensing signal. The type indication function of the first indication, that is, whether the first indication indicates the type of the sensing signal, can be enabled or disabled via higher layer signaling. The system can dynamically configure whether to use the first indication for this purpose or rely on other signaling methods, thereby improving the overall flexibility. In some cases, the system may be pre-configured to support a single type of sensing signal (UL, DL or SL) . This pre-configuration simplifies the system operation and reduces the complexity of signaling. By pre-configuring the type, the system can eliminate the need for additional signaling to indicate the type during operation. This reduces the signaling overhead and facilitates a more efficient communication.
[0149] In an implementation, in order to indicate the location (e.g., time position) of the second occasion, at least one of a starting time of the one or more corresponding second occasions, a period of the one or more corresponding second occasions or a time offset of the one or more corresponding second occasions relative to a reference time is configured. When the period of the one or more corresponding second occasions is configured, a time domain position of each of the one or more corresponding second occasions can be determined based on the period and the starting time of the first one of the one or more corresponding second occasions, or based on the period and a time offset of the one or more corresponding second occasions relative to a reference time. The reference time may be the occasion of a synchronization signal block (SSB) transmission, a system frame number (SFN) , or a subframe or slot number. In an implementation, the corresponding second occasion may be indicated by a time offset between the first occasion and the second occasion. In this way, the timing for receiving the sensing signals can be easily determined based on the first occasion and the time offset between the first occasion and the second occasion.
[0150] In an implementation, the one or more sensing related measurements may include at least one of: one or more downlink sensing measurements, one or more uplink sensing measurements, or one or more sidelink sensing measurements.
[0151] The processes related to the downlink sensing measurement, the uplink sensing measurement and sidelink sensing measurement are further described in detail as follows.
[0152] Downlink sensing measurement
[0153] The terminal device monitors a first indication in a first occasion, wherein the first indication indicates either activation or deactivation of reception of one or more sensing signals in one or more corresponding second occasions. The one or more sensing signals may be used for performing downlink sensing measurement by the terminal device. The sensing signal is a downlink sensing signal. When the first indication indicates activation of reception of one or more sensing signals in one or more corresponding second occasions, the terminal device would monitor and receive the sensing signal. When the first indication indicates deactivation of reception of the one or more sensing signals, the terminal device would skip reception of the one or more sensing signals. The first indication can be a WUS (or LP-WUS) or DCI or MAC CE. The first indication may further indicate a type of each of the one or more sensing signals, the type being a downlink sensing signal. The first indication may further indicate a type of each of the one or more sensing signals, the type indicating a kind of the downlink sensing signal which may include a demodulation reference signal (DMRS) , a channel state information reference signal (CSIRS) , a synchronization signal block (SSB) , a positioning reference signal (PRS) , a phase tracking reference signal (PTRS) , or sensing reference signal (SERS) .
[0154] One or more sets of configurations are configured, and each of the one or more sets of configurations indicates one or more of: the first occasion; the second occasion and a reporting resource for reporting a result of a sensing related measurement based on the sensing signal. The one or more sets of configurations may be configured via higher layer signaling.
[0155] In an implementation, the first occasion can be indicated by a period of the first indication and a time offset between the first occasion and a reference time. The reference time may be the occasion of a synchronization signal block (SSB) transmission, a system frame number (SFN) , or a subframe or slot number. In an implementation, the first occasion may be configured to be specific to the terminal device (i.e., a first device) which monitors the first indication.
[0156] In an implementation, the second occasion may be indicated. As described above, it is possible to indicate the second occasion corresponding to each of the one or more sensing signals by configuring at least one of a starting time of the one or more corresponding second occasions, a period of the one or more corresponding second occasions or a time offset of the one or more corresponding second occasions relative to a reference time.
[0157] In an implementation, the reporting resource may be indicated by a time offset between the second occasion and the reporting resource, or the reporting resource is indicated by a time offset between the first occasion and the reporting resource. The reporting resource may indicate a specific communication channel or resource that the device should use to report the result of the sensing-related measurement to the network or other relevant entities. The reporting resource can be a PUCCH (physical uplink control channel) , or PUSCH (physical uplink shared channel) . Designating a specific reporting resource can ensure that the sensing measurement results are transmitted efficiently and reliably. A preconfigured offset between the activated sensing signal and the reporting can avoid overhead due to dynamic signaling.
[0158] When multiple sets of configurations are configured, each of the multiple sets of configurations may be associated with a CF ID. The first indication may carry the CF ID to indicate which CF will be applied to the sensing signal that follows the first indication and the associated sensing report configuration. In this case, the terminal device can detect the sensing signal after a time offset of the first occasion according to the corresponding CF.
[0159] The terminal device can receive the sensing signal in the corresponding second occasion, perform sensing related measurement (downlink sensing measurement) and report a result of the downlink sensing measurement using the reporting resource. The result of the downlink sensing measurement is obtained by measuring the sensing signal.
[0160] FIG. 9 is a schematic illustration of a method for downlink sensing measurement according to one or more embodiments of the present disclosure. As shown in FIG. 9, a LP-WUS is taken as an example of the first indication for illustration purposes.
[0161] Step 1: Specific parameters for a sensing task are configured for a UE (that is, the terminal device) . Higher layer sensing signaling configuration (depicted as CF in FIG. 9) is used to configure UE specific LP-WUS, DL SERS (a specific example of the aforementioned downlink sensing signal) transmission, and / or the sensing report resources. In FIG. 9, a single set of configurations, that is, CF0 shown in FIG. 9, is configured. The CF includes an LP-WUS monitoring occasion (a specific example of the aforementioned first occasion) for triggering SERS, SERS configuration, offset between activated LP-WUS and SERS, the associated PUCCH / PUSCH resources for SERS reporting (a specific example of the aforementioned reporting resource) , offset between SERS and PUCCH / PUSCH. Typically, the higher layer signaling can be RRC signaling, MAC CE signaling or LPP signaling or the signaling between sensing function entity in core network and UE. The LP-WUS monitoring occasion for triggering SERS may be indicated by a period of the LP-WUS monitoring occasion and a time offset between the LP-WUS monitoring occasion and a reference time. The SERS configuration may include a first time-frequency position in the corresponding second occasion (shown as the block SERS in FIG. 9) for receiving the SERS.
[0162] Step 2: The UE in ultra-deep sleep mode monitors LP-WUS according to the higher layer sensing signaling, until the active LP-WUS is detected.
[0163] Step 3: When LP-WUS is detected, the UE wakes up from ultra-deep sleep mode and prepares to perform sensing measurements. The UE continues to detect the SERS after a timing offset of the LP-WUS monitoring occasion according to higher layer sensing signaling. LP-WUS may indicate the activated or deactivated SERS transmission type e.g., DL SERS or UL SERS transmission or both. If the SERS is already active, the LP-WUS can deactivate it, allowing the UE to return to sleep mode.
[0164] Step 4: The UE measures the SERS and reports sensing results in the PUCCH / PUSCH after a timing offset of the SERS according to the higher layer sensing signaling.
[0165] Step 5: After the transmission of the sensing report, the UE returns to deep sleep LP-WUS monitoring state.
[0166] FIG. 10 is a schematic illustration of a method for downlink sensing measurement according to one or more embodiments of the present disclosure. As shown in FIG. 10, a LP-WUS is taken as an example of the first indication for illustration purposes.
[0167] Step 1: Specific parameters for a sensing task are configured for a UE (that is, the terminal device) . Multiple configurations (depicted as CF in FIG. 10) are used to configure UE specific LP-WUS and sensing measurement and report transmission. The multiple sets of configurations can be indicated by a configuration list (that is, a set of CF) and each configuration associates with a configuration (CF) ID. As shown in FIG. 10, CF0 and CF1 are configured. Each of the CFs indicates LP-WUS monitoring occasion (that is, the first occasion) for triggering SERS, SERS configuration, offset between activated LP-WUS and SERS, the associated PUCCH / PUSCH resources for SERS reporting (a specific example of the aforementioned reporting resource) , and / or offset between SERS and PUCCH / PUSCH. The multiple configurations may be configured via higher layer signaling. The higher layer signaling can be RRC signaling, MAC CE signaling or LPP signaling. The LP-WUS monitoring occasion for triggering SERS may be indicated by a period of the LP-WUS monitoring occasion and a time offset between the LP-WUS monitoring occasion and a reference time (e.g., the time at which the CF is received) . The SERS configuration may include a first time-frequency position in the corresponding second occasion (depicted as the block SERS in FIG. 10) for receiving the SERS. Information in the CFs may be directly or indirectly informed. Some CFs may share similar information, then it is not required to explicitly notify the similar information, a reference to such information may be enough. For example, the LP-WUS monitoring occasion for triggering SERS may be same for the multiple configurations, so the LP-WUS monitoring occasion may be notified once, and each CF may include an indication of the LP-WUS monitoring occasion. Or some common information can be configured for more than one CFs. For example, a separate common information can be configured which applies to the more than one CFs.
[0168] Step 2: The UE in ultra-deep sleep mode monitors LP-WUS according to the CF0, until the active LP-WUS is detected.
[0169] Step 3: When the LP-WUS is detected, the UE wakes up from ultra-deep sleep mode and prepares to perform sensing measurements. The detected LP-WUS carrying the CF ID indicates which CF will be applied to the following SERS and the associated sensing report configuration. In this case, CF0 is applied to the subsequent DL SERS transmission. LP-WUS may indicate the activated or deactivated SERS transmission type e.g. DL SERS or UL SERS transmission or both.
[0170] Step 4: The UE detects the SERS after a timing offset of the LP-WUS according to the corresponding CF0.
[0171] Step 5: The UE measures the SERS and reports sensing results in a PUCCH / PUSCH after a timing offset of the SERS according to the CF0.
[0172] Step 6: After transmission of the sensing report, the UE returns to deep sleep LP-WUS monitoring state.
[0173] The UE, in ultra-deep sleep mode, continues monitoring for the LP-WUS, until the active LP-WUS is detected. The UE then performs the downlink sensing measurement according to CF1 indicated by the detected LP-WUS, which is similar to steps 3-6 described above.
[0174] Uplink sensing measurement
[0175] The terminal device monitors a first indication in a first occasion, wherein the first indication indicates either activation or deactivation of transmission of one or more sensing signals in one or more corresponding second occasions. The one or more sensing signals may be used for performing uplink sensing measurement by the network device. The sensing signal is an uplink sensing signal. When the first indication indicates activation of transmission of one or more sensing signals in one or more corresponding second occasions, the terminal device would transmit the sensing signal. When the first indication indicates deactivation of transmission of the one or more sensing signals, the terminal device would skip transmission of the one or more sensing signals. The first indication can be a WUS (or LP-WUS) or DCI or a MAC CE. The first indication may further indicate a type of each of the one or more sensing signals, the type being an uplink sensing signal. The first indication may further indicate a type of each of the one or more sensing signals, the type indicating a kind of the uplink sensing signal which may include a demodulation reference signal (DMRS) , a sounding reference signal (SRS) , a positioning reference signal (PRS) , a phase tracking reference signal (PTRS) , or a sensing reference signal (SERS) .
[0176] One or more sets of configurations are configured, and each of the one or more sets of configurations indicates one or more of: the first occasion; and the sensing signal. The one or more sets of configurations may be configured via higher layer signaling.
[0177] In an implementation, the first occasion can be indicated by a period of the first indication and a time offset between the first occasion and a reference time. The reference time may be the occasion of a synchronization signal block (SSB) transmission, a system frame number (SFN) , a subframe number or slot number. The first occasion may be configured to be specific to the terminal (afirst device) which monitors the first indication.
[0178] In an implementation, the second occasion may be indicated. As described above, it is possible to indicate the second occasion corresponding to each of the one or more sensing signals by configuring at least one of a starting time of the one or more corresponding second occasions, a period of the one or more corresponding second occasions or a time offset of the one or more corresponding second occasions relative to a reference time.
[0179] In an implementation, when the first indication indicates the activation of the sensing signal in the corresponding second occasion, the terminal device may transmit the sensing signal in the second occasion. When the first indication indicates deactivation of the one or more sensing signals, the terminal device may skip transmission of the one or more sensing signals at the second time-frequency position. A preconfigured offset between the first indication and the UL sensing signal transmission can avoid overhead due to dynamic signaling.
[0180] When multiple sets of configurations are configured, each of the multiple sets of configurations may be associated with a CF ID. The first indication may carry the CF ID to indicate which CF will be applied to the following UL sensing signal transmission. In this case, the terminal device can transmit the UL sensing signal after a time offset of the first occasion according to the corresponding CF. The network device which receives the UL sensing signal can measure the UL sensing signal (that is, perform uplink sensing measurement) . The network device can use the UL sensing measurements for sensing assisted communication e.g., beam management. Alternatively, the network device (e.g., a base station) can report the measurement results to the sensing function entity in the core network.
[0181] FIG. 11 is a schematic illustration of a method for uplink sensing measurement according to one or more embodiments of the present disclosure. As shown in FIG. 11, an LP-WUS is taken as an example of the first indication for illustration.
[0182] Step 1: Specific parameters for a sensing task are configured for a UE (that is, the terminal device) . Higher layer sensing signaling is used to configure UE-specific LP-WUS and UL SERS transmission (that is, the uplink sensing signal) . In FIG. 11, a single set of configurations, that is, CF0 shown in FIG. 11, is configured. The CF includes LP-WUS monitoring occasion (a specific example of the aforementioned first occasion) for triggering UL SERS, UL SERS configuration, and / or an offset between the activated LP-WUS and the UL SERS. The LP-WUS monitoring occasion for triggering SERS may be indicated by a period of the LP-WUS monitoring occasion and a time offset between the LP-WUS monitoring occasion and a reference time. The UL SERS configuration may include a second time-frequency position in the corresponding second occasion (shown as the block SERS in FIG. 11) for transmitting the UL SERS.
[0183] Step 2: The UE, in ultra-deep sleep mode, monitors LP-WUS according to the higher layer sensing signaling, until the active LP-WUS is detected.
[0184] Step 3: When the LP-WUS is detected, the UE wakes up from the ultra-deep sleep mode. When the UL SERS transmission is activated, the UE transmits UL SERS after a timing offset of the LP-WUS monitoring occasion according to the higher layer sensing signaling.
[0185] Step 4: After transmission of the UL SERS, the UE returns to deep sleep LP-WUS monitoring state.
[0186] FIG. 12 is a schematic illustration of a method for uplink sensing measurement according to one or more embodiments of the present disclosure. As shown in FIG. 12, an LP-WUS is taken as an example of the first indication for illustration purposes.
[0187] Step 1: Specific parameters for a sensing task are configured for a UE (that is, the terminal device) . Multiple configurations (CF) are used to configure UE-specific LP-WUS and UL SERS (a specific example of the aforementioned uplink sensing signal) transmission. The multiple sets of configurations can be indicated by a configuration list (that is, a set of CFs) and each configuration is associated with a configuration (CF) ID. As shown in FIG. 12, CF0 and CF1 are configured. Each of the CFs indicates LP-WUS monitoring occasion (a specific example of the aforementioned first occasion) for triggering UL SERS, UL SERS configuration, and / or the offset between activated LP-WUS and UL SERS. The multiple configurations may be configured via higher layer signaling. The higher layer signaling can be RRC signaling, MAC CE signaling or LPP signaling or the signaling between sensing function entity in the core network and the UE. The LP-WUS monitoring occasion for triggering SERS may be indicated by a period of the LP-WUS monitoring occasion and a time offset between the LP-WUS monitoring occasion and a reference time. The UL SERS configuration may include a second time-frequency position in the corresponding second occasion (shown as the block SERS in FIG. 12) for transmitting the UL SERS. Information in the CFs may be directly or indirectly informed. Some CFs may share similar information, in which case it is not required to explicitly notify the similar information, and just a reference to such information may be sufficient. For example, the LP-WUS monitoring occasion for triggering the SERS may be the same for multiple configurations, and therefore, the LP-WUS monitoring occasion may be notified once, and each CF may include an indication of the LP-WUS monitoring occasion. In other implementations, common information can be configured for more than one CFs. For example, a separate common information can be configured which applies to more than one CF.
[0188] Step 2: The UE, in ultra-deep sleep mode, monitors the LP-WUS according to the CF, until the active LP-WUS is detected.
[0189] Step 3: When the LP-WUS is detected, the UE wakes up from ultra-deep sleep mode. The detected LP-WUS carrying the CF ID indicates which CF is applied to the UL SERS transmission. In this case, CF0 is applied to the subsequent UL SERS transmission.
[0190] Step 4: The UE transmits UL SERS after a timing offset of LP-WUS according to the CF0.
[0191] Step 5: After transmission of the UL, the UE returns to deep sleep LP-WUS monitoring state.
[0192] The UE, in ultra-deep sleep mode, continues monitoring of the LP-WUS, until the active LP-WUS is detected. The UE then performs the uplink sensing measurement according to CF1 indicated by the detected LP-WUS, which is similar to steps 3-5 described above.
[0193] Sidelink sensing measurement
[0194] The terminal device monitors a first indication in a first occasion, wherein the first indication indicates either activation or deactivation of transmission and / or reception of one or more sensing signals in one or more corresponding second occasions. The one or more sensing signals may be used for performing sidelink sensing measurement. The sensing signal is a sidelink sensing signal. When the first indication indicates activation of reception of one or more sensing signals in one or more corresponding second occasions, the terminal device monitors and receives the sensing signal. When the first indication indicates activation of transmission of one or more sensing signals in one or more corresponding second occasions, the terminal device transmits the sensing signal in one or more corresponding second occasions. When the first indication indicates deactivation of transmission and / or reception of the one or more sensing signals, the terminal device skips transmission and / or reception of the one or more sensing signals. The first indication can be a WUS (or an LP-WUS) or a DCI or a MAC CE. The first indication may further indicate a type of each of the one or more sensing signals, the type being a sidelink sensing signal.
[0195] One or more sets of configurations are configured, and each of the one or more sets of configurations indicates one or more of: the first occasion, and the second occasion. The one or more sets of configurations may be configured via higher layer signaling. In an implementation, the first occasion can be indicated by a period of the first indication and a time offset between the first occasion and a reference time. The reference time may be the occasion of a synchronization signal block (SSB) transmission, a system frame number (SFN) , a subframe number or a slot number. The first occasion may be configured to be specific to the terminal (i.e., a first device) which monitors the first indication. In an implementation, the second occasion may be indicated. As described above, it is possible to indicate the second occasion corresponding to each of the one or more sensing signals by configuring at least one of a starting time of the one or more corresponding second occasions, a period of the one or more corresponding second occasions or a time offset of the one or more corresponding second occasions relative to a reference time.
[0196] If the communication of the sidelink sensing signal is from a further device to the terminal device which monitors the first indication, the first indication may indicate activation of reception of one or more sidelink sensing signals in one or more corresponding second occasions by the terminal device. The terminal device would monitor and receive the sidelink sensing signal. The first indication may be transmitted by the further device or by a network device. The terminal device may transmit a result of the sidelink sensing measurement to the further device which transmits the sidelink sensing signal to the network device. In this case, the principle of the sidelink sensing measurement is similar to the downlink sensing measurement.
[0197] If the communication of the sidelink sensing signal is from the terminal device which monitors the first indication to a further device, the first indication may indicate activation of transmission of one or more sidelink sensing signals in one or more corresponding second occasions by the terminal device. The terminal device would transmit the sidelink sensing signal to the further device. The first indication may be transmitted by a network device. The further device may transmit a result of the sidelink sensing measurement to the terminal device which transmits the sidelink sensing signal to the network device. The further device may also monitor an indication which indicates activation of reception of one or more sidelink sensing signals in one or more corresponding second occasions by the further device. This indication may be transmitted by the terminal device or the network device. In this case, the principle of the sidelink sensing measurement is similar to the uplink sensing measurement.
[0198] FIG. 13 is a schematic flowchart of a method according to one or more embodiments of the present disclosure. The method shown in FIG. 13 is implemented by a network device. It should be understood that the method shown in FIG. 13 can also be realized by other devices, such as chips or communication devices with communication capabilities. As shown in FIG. 13, the method can include the following steps.
[0199] At S1301, transmit a first indication in a first occasion, where the first indication indicates either activation or deactivation of transmission and / or reception of one or more sensing signals in one or more corresponding second occasions.
[0200] In an implementation, the first indication is transmitted by a network device.
[0201] In an implementation, one or more sets of configurations may be configured, and each of the one or more sets of configurations indicates one or more of: the first occasion; the second occasion; a reporting resource for reporting a result of the sensing related measurement based on the sensing signal.
[0202] In an implementation, the reporting resource may be indicated by a time offset between the second occasion and the reporting resource, or the reporting resource is indicated by a time offset between the first occasion and the reporting resource.
[0203] In an implementation, when the first indication indicates the activation of the sensing signal in the corresponding second occasion, the sensing signal may be transmitted in the second occasion.
[0204] When the sensing signal is a downlink sensing signal, the downlink sensing signal may be transmitted by a network device and received by a terminal device which monitors for the first indication, and in an implementation, the terminal device performs downlink sensing measurement using the downlink sensing signal, and the network device may receive a result of the downlink sensing measurement reported by the terminal device.
[0205] When the sensing signal is a sidelink sensing signal, the sidelink sensing signal may be transmitted by a further device and received by the terminal device which monitors for the first indication. In an implementation, the terminal device performs sidelink sensing measurement using the sidelink sensing signal, and the further device may receive a result of the sidelink sensing measurement reported by the terminal device.
[0206] In an implementation, one or more sets of configurations may be configured, and each of the one or more sets of configurations indicates one or more of: the first occasion, and / or the second occasion.
[0207] In an implementation, when the first indication indicates the activation of the sensing signal in the corresponding second occasion, the sensing signal may be received in the second occasion.
[0208] When the sensing signal is an uplink sensing signal, the uplink sensing signal may be transmitted by a terminal device which monitors for the first indication received by a network device. The network device may then perform uplink sensing measurement using the uplink sensing signal.
[0209] When the sensing signal is a sidelink sensing signal, the sidelink sensing signal may be transmitted by the terminal device which monitors for the first indication and received by a further device. The further device may then perform sidelink sensing measurement using the sidelink sensing signal.
[0210] In an implementation, when the sets of configurations are configured, the first indication further indicates at least one of the sets of configurations.
[0211] In an implementation, the one or more sets of configurations is configured via higher layer signaling. For example, the CN may transmit the higher layer signaling to the network device which performs uplink / downlink communication with the terminal device or a further device which performs sidelink communication with the terminal device, so that the network device or the further device can perform communication with the terminal device which monitors for the first indication effectively.
[0212] In an implementation, the higher layer signaling includes at least one of radio resource control (RRC) signaling, media access control element (MAC CE) signaling, or long term evolution positioning protocol (LPP) signaling.
[0213] In an implementation, the first occasion is indicated by a period of the first indication and a time offset between the first occasion and a reference time.
[0214] In an implementation, the corresponding second occasion is indicated by a time offset between the first occasion and the second occasion.
[0215] In an implementation, the first occasion is configured to be specific to a first device which monitors the first indication.
[0216] In an implementation, when the first indication indicates deactivation of the one or more sensing signals, the network device / the further device may skip transmission and / or reception of the one or more sensing signals.
[0217] In an implementation, the first indication further indicates whether a type of each of the one or more sensing signals is a downlink sensing signal, an uplink sensing signal, or a sidelink sensing signal.
[0218] In an implementation, at least one of a starting time of the one or more corresponding second occasions, a period of the one or more corresponding second occasions or a time offset of the one or more corresponding second occasions relative to a reference time is configured.
[0219] In an implementation, the one or more sensing related measurements include at least one of: one or more downlink sensing measurements; one or more uplink sensing measurements; or one or more sidelink sensing measurements.
[0220] In an implementation, the one or more sensing signals are used for one or more sensing related measurements.
[0221] In an implementation, the first indication is carried in a wake-up signal (WUS) or downlink control information (DCI) , or a medium access control control element (MAC CE) .
[0222] In the present disclosure, higher layer signaling configuration {LP-WUS, SERS and sensing measurement and report} with on-demand LP-WUS activation / deactivation is proposed. In this way, activation / deactivation of higher layer configured sensing parameters can be achieved with a low power signal to achieve high power saving gain for sensing.
[0223] In some implementations, a UE-specific LP-WUS and sensing measurement and report information are configured by higher layer signaling. The sensing CF information may include {sensing CF list, sensing CF ID, LP-WUS monitoring occasion (period and offset) , LP-WUS supporting indication of DL SERS activation / deactivation, LP-WUS supporting indication of UL SERS indication activation / deactivation, offset between activated / deactivated LP-WUS and DL SERS, offset between activated / deactivated LP-WUS and UL SERS, DL &UL SERS configuration, the associated PUCCH / PUSCH resources for DL SERS reporting, offset between DL SERS and PUCCH / PUSCH} . Single or multiple sensing configuration parameters for DL SERS activation / deactivation and sensing report or UL SERS activation or deactivation are preconfigured for LP-WUS activation / deactivation. By preconfiguring the sensing parameters, the need for dynamic signaling to configure these parameters can be avoided, which reduces the complexity and overhead of signaling. The preconfiguration can enable the terminal device to enter low-power states when sensing is not required, which conserves power of the terminal device.
[0224] The LP-WUS indicates DL SERS or UL SERS activation / deactivation (UE monitors LP-WUS for deciding whether DL SERS or UL SERS is activated / deactivated according to the sensing CF configuration or same LP-WUS with different occasions for DL &UL SERS activation / deactivation) . By using the proposed on-demand LP-WUS for activating / deactivating DL SERS measurement and report and / or UL SERS transmission, flexible low power activation / deactivation of SERS can be achieved, which is quite flexible compared to 5G PRS only with periodic configuration.
[0225] For DL SERS, the UE detects DL SERS after a timing offset relative to the LP-WUS according to the CF, the preconfigured timing offset avoids dynamic indication, and therefore overhead and power consumption will be reduced. The UE may also report sensing results in the PUCCH / PUSCH after a timing offset relative to the SERS according to the CF. This preconfigured offset between activated SERS and reporting avoids overhead of dynamic signaling.
[0226] For UL SERS, UE transmits UL SERS after a timing offset relative to LP-WUS according to CF. This preconfigured offset between the LP-WUS and UL SERS transmission avoids overhead of dynamic signaling.
[0227] Multiple sensing CFs may be used to configure UE-specific LP-WUS and DL SERS sensing measurement and report information, or DL and UL SERS configuration. Each sensing CF associates with a sensing CF ID. LP-WUS indicates sensing CF ID for DL SERS and sensing report configuration; or LP-WUS indicates sensing CF ID for UL SERS transmission. LP-WUS activates / deactivates one or multiple CFs for DL SERS transmission and report configuration or UL SERS transmission. In this way, low power state activation of multiple configurations for DL sensing measurement and report or UL sensing RS transmission can be supported.
[0228] As described above, the present disclosure provides an on-demand low power sensing activation or deactivation method. The higher layer signaling configured parameters {LP-WUS, DL SERS, UL SERS, UL sensing report resources} with on-demand LP-WUS activation / deactivation are proposed. LP WUS which can be used for activating / deactivating DL SERS and its measurement and report are also introduced. LP WUS which can be used for activating / deactivating UL SERS is also introduced. Both single and multiple higher layer sensing signaling configurations can be supported.
[0229] The configuration information includes one or more of the following items: Multiple configuration list, configuration ID; LP-WUS monitoring occasion; LP-WUS supporting activate / deactivate DL SERS indication; LP-WUS supporting indication of UL SERS activation / deactivation; LP-WUS supporting indication of activation / deactivation both DL and UL SERS; an offset between activated / deactivated LP-WUS and DL SERS; an offset between activated / deactivated LP-WUS and UL SERS; DL / UL SERS configuration; or, an offset between DL SERS and PUCCH / PUSCH.
