It uses the propagation characteristics of electric waves to depict and reconstruct the physical world, achieving a sensing network. Through the synergy of network sensing and terminal sensing, the physical world covered by the entire network can be modeled, and sensing-assisted communication and communication-assisted sensing can be provided. ISAC is an emerging technology that combines wireless communication and sensing capabilities.

[0030] In the following, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. In the description, specific terminology and descriptions are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in various ways and should not be construed as being limited to the embodiments set forth herein. Unless otherwise defined, technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this present invention belongs. It will be further understood that the terms of a given

[0031] It is also to be noted that, in this specification, well-known technologies or functions are not described in detail since they would obscure the disclosure in unnecessary detail. Moreover, it is to be understood that the phraseology and terminology used herein is for the purpose of description and explanation only and are not necessarily limiting.

[0032] FIG. 2a is a schematic diagram illustrating a single transceiver device sensing mode; and FIG. 2b is a schematic diagram illustrating a multi-device cooperative reception sensing mode.

[0033] When a pair of transceivers (single UE-single gNB) is used as shown in FIG. 2a, the frequency change of the specific action of the sensing object can be zero. Therefore, the action segment can not be detected. Therefore, multiple devices are needed to construct the frequency curve and extract a series of direction changes, which cannot be achieved by a single pair of transceivers. The present application considers using a multi-device cooperative reception sensing mode (single UE-multiple gNB) as shown in FIG. 2b to achieve sensing.

[0034] FIG. 3 shows a network architecture suitable for sensing services with new radio (NR) access according to an embodiment of the present disclosure.

[0035] As shown in FIG. 3, the AMF (access and mobility management function) of the core network receives a sensing service (which can also be referred to as a sensing task) request related to a specific target UE from other entities (such as a UE), or the AMF itself decides to start a sensing service on behalf of a specific target UE. Then, the AMF sends a sensing service request to the SF (sensing function) of the core network. The SF processes the sensing service request, which can include transmitting assistance data to the target UE to assist in UE-based and / or UE-assisted sensing and / or sensing of the target UE. Then, the SF returns the result of the sensing service to the AMF (e.g., the location estimate of the UE). In the case of a sensing service requested by an entity other than the AMF (such as a UE), the AMF returns the sensing service result to the entity. In FIG. 3, NR-Uu represents the interface between the UE and the gNB, Xn represents the interface between the gNB and the gNB, NS1 represents the interface between the AMF and the SF, NG-C represents the interface between the AMF and the gNB, and NG-RAN is an abbreviation for next generation wireless access network.

[0036] The present disclosure provides an electronic device 400 in a communication-sensing integrated system according to an embodiment of the present disclosure, comprising: at least one processor; and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the electronic device 400 to perform: for a sensing task related to a user equipment within a service range of the electronic device 400, performing the sensing task based on an uplink reference signal, together with a cooperative electronic device for cooperating to complete the sensing task.

[0037] FIG. 4 shows an exemplary functional module block diagram of an electronic device 400 in a communication-sensing integrated system according to an embodiment of the present disclosure.

[0038] As shown in FIG. 4, the electronic device 400 includes a control unit 401 which performs control, and a processing unit 403 which can be configured to perform, under control of the control unit 401, a sensing task for a user equipment in a service range (i.e., coverage) of the electronic device 400, based on an uplink reference signal, together with a cooperative electronic device for cooperatively completing the sensing task.

[0039] The control unit 401 and the processing unit 403 can be implemented as one or more processing circuits, such as a processor or a chip, and at least one memory, such as a RAM, a ROM, etc., for storing computer program codes and data required by the processing circuit for processing, etc. It should be understood that the various functional units in the electronic device 400 shown in FIG. 4 are only logical modules divided according to the specific functions they implement, and are not intended to limit the specific implementation manner.

[0040] The electronic device 400 can be disposed at a base station side or communicatively connected to a base station, for example. For example, the electronic device 400 can work as the base station itself, and can further include external devices such as a memory, a transceiver (not shown), etc. The memory can be used to store programs and related data information required by the electronic device 400 to implement various functions. The transceiver can include one or more communication interfaces to support communication with different devices (e.g., UE, base station, etc.), and the implementation form of the transceiver is not specifically limited here.

[0041] As an example, the base station can be an eNB or a gNB, for example.

[0042] For example, the sensing task related to the user equipment can include UE-based and / or UE-assisted sensing and / or target UE sensing.

[0043] According to embodiments of the present disclosure, the sensing task can be implemented by UE uplink cooperation with multiple base stations (the electronic device 400 and the cooperative electronic device) based on the uplink reference signal.

[0044] As an example, the uplink reference signal includes an uplink channel sounding reference signal (SRS) or a demodulation reference signal (DMRS).

[0045] Hereinafter, for the sake of simplicity, the electronic device 400 is sometimes referred to as a master base station, the uplink reference signal is sometimes referred to as an uplink sensing reference signal or a sensing reference signal, and the cooperative electronic device is sometimes referred to as a cooperative base station.

[0046] As an example, the cooperating electronic device is selected by the core network based on the result of the measurement of the uplink reference signal. For example, the selection of the cooperating electronic device can be made according to the comparison of the reference signal received power (RSRP) values of the uplink reference signal measured by the other base stations around the main base station, or according to the location information of the other base stations, according to different sensing service requirements, and the cooperating electronic device for cooperating sensing is selected. Among them, the cooperating electronic device can cover the UE.

[0047] As an example, the processing unit 403 can be configured to determine the time-frequency resource and configuration information of the uplink reference signal based on the request received from the core network. In order to obtain the uplink measurement value, the base station needs to know the characteristics of the sensing reference signal transmitted by the UE in the time period required for performing the uplink measurement. These characteristics should be static in the periodic sensing reference signal transmission during the uplink measurement. Therefore, the SF will indicate to the main base station that it is necessary to guide the UE to transmit the sensing reference signal for uplink sensing.

[0048] For each resource set configured by SRS-ResourceSet, the UE can be configured with K≥1 SRS resources by the upper layer parameter SRS-Resource, where the maximum value of K is determined by the capability of the UE.

[0049] The IE SRS-Config (all configured IEs for SRS) is used to configure reference signal transmission. The configuration defines the list of SRS-Resources, the list of SRS-PosResources, the list of SRS-PosResourceSets, and the list of SRS-ResourceSets. Each resource set defines a set of SRS-Resources or SRS-PosResources. The network triggers the transmission of a set of SRS-Resources or SRS-PosResources using the configured aperiodic SRS-ResourceTrigger (L1 DCI).

[0050] Reference TS38.331 6.3.2 Radio resource control information elements SRS-Config (Radio Resource Control Information Elements SRS-Config) gives the SRS resource set configuration.

[0051] Reference TS38.331 6.3.2 Radio resource control information elements SRS-Config (Radio Resource Control Information Elements SRS-Config) gives the SRS resource configuration.

[0052] NR DMRS can be transmitted in multiple schemes, for example including time domain DMRS and frequency domain DMRS. The selection of the scheme depends on the specific NR configuration and requirements. Time domain DMRS refers to DMRS symbols distributed in different slots within a subframe. Frequency domain DMRS refers to DMRS symbols distributed on different frequency resources within a subcarrier spacing.

[0053] Referring to 3GPP NR Positioning 5G Positioning standard, IE DMRS-UplinkConfig is used to configure the uplink demodulation reference signal of PUSCH.

[0054]

[0055] In the following, for the sake of simplicity, the above description is given by taking SRS as an example of uplink reference signal. It is understood by those skilled in the art that the description given below by taking SRS as an example is also applicable to DMRS.

[0056] Referring to Table 8.13.2.1-1 in 3GPP NR Positioning 5G Positioning standard, the perceived reference signal configuration information (UE configuration data that may be transferred from serving gNB to the SF) that can be fed back from the main base station to the SF is listed (TS38.305 8.13).

[0057]

[0058]

[0059] Referring to Table 8.13.2.3-1 in 3GPP NR Positioning 5G Positioning standard, the requested UL-SRS transmission characteristics information that can be sent from the SF to the gNB is listed.

[0060] As described above, the SF sends a message to the main base station requesting the configuration information of the uplink reference signal, and if the message includes the requested UL-SRS transmission characteristics information similar to that listed in Table 8.13.2.3-1, the main base station should consider this information when configuring the UL-SRS transmission for the UE.

[0061] As an example, the processing unit 403 can be configured to send the time-frequency resource and configuration information of the uplink reference signal to the core network, for the core network to send the time-frequency resource and configuration information to the cooperating electronic device for the cooperating electronic device to perform the sensing task (for the cooperating electronic device to receive and decode the uplink reference signal to perform the sensing task).

[0062] As an example, the processing unit 403 can be configured to configure the user equipment with the uplink reference signal through RRC reconfig based on the time-frequency resource and configuration information of the uplink reference signal.

[0063] As an example, the processing unit 403 can be configured to activate or deactivate the semi-persistent uplink reference signal through a medium access control control element (MAC CE).

[0064] As an example, the processing unit 403 can be configured to activate or deactivate the aperiodic uplink reference signal through downlink control information (DCI).

[0065] For example, for semi-persistent and aperiodic SRS, the SF requests the primary base station to activate or deactivate the sensing reference signal (that is, the SF sends a sensing activation / deactivation request message to the primary base station to request the primary base station to activate / deactivate the UL-SRS for the UE), and skips if it is a periodic sensing reference signal.

[0066] For semi-persistent UL sensing reference signals, the primary base station can activate the configured semi-persistent UL sensing reference signal resource set by sending a sensing reference signal activation / deactivation MAC CE command. For aperiodic UL sensing reference signals, the primary base station can activate the configured aperiodic UL-sensing reference signal resource set by sending a TS DCI.

[0067] Referring to Table 8.13.2.3-3 in 3GPP NR Positioning 5G Positioning standard, the Requested activation / deactivation information that can be sent from the SF to the primary base station is listed.

[0068]

[0069] As an example, the processing unit 403 can be configured to report the sensing data obtained based on the uplink reference signal to the core network, for the core network to fuse the sensing data and the sensing data from the cooperating electronic device to obtain a sensing result of the sensing task.

[0070] As an example, the sensing data includes at least one of a detection probability, a phase, and a power of the uplink reference signal.

[0071] Referring to Table 8.13.2.2-1 in 3GPP NR Positioning 5G Positioning Standard, Measurement results that may be transferred from gNBs to the SF (TS38.305 8.13) are listed.

[0072] FIG. 5 shows an example of an uplink sensing reference signal-based sensing measurement processing flow according to an embodiment of the present disclosure. For ease of description, in this flow example, the uplink sensing reference signal is simply referred to as a sensing reference signal.

[0073] Step 1: The SF requests the UE to report its sensing-related capabilities, and then the UE reports its capability information.

[0074] Not all devices in the network support sensing functions, for example, only a part of the UEs support sensing functions and can interact with the SF; in addition, each network element plans its own service area. Therefore, in order to successfully execute the sensing service request, the device supporting the sensing function needs to inform the sensing network element SF of its sensing capability. The requirements involved in different sensing services are different, and the SF will specifically query the UE's capability according to the sensing service requirement. The capability of the UE is used for the main base station to configure the sensing reference signal. The capability of the UE may include, for example, the transmission period of the sensing reference signal (e.g., the SRS transmission period) and the like.

[0075] Step 2: The SF requests the main base station for the time-frequency resource and configuration information of the sensing reference signal.

[0076] As described above, in order to obtain the uplink measurement value, the gNB needs to know the characteristics of the sensing reference signal transmitted by the UE in the time period required for performing the uplink measurement. These characteristics should be static in the periodic sensing reference signal transmission during the uplink measurement. Therefore, the SF will indicate to the main base station that it is necessary to guide the UE to transmit the sensing reference signal for uplink sensing.

[0077] Step 3: The main base station decides the resource and configuration information of the available sensing reference signal.

[0078] Step 4: The main base station configures the sensing reference signal for the UE through RRC reconfig by using the decided resource and configuration information of the sensing reference signal;

[0079] Step 5: The main base station informs the SF of the resource and configuration information of the sensing reference signal.

[0080] The main base station finally decides the resources of the sensing reference signal to be allocated, and transmits the sensing reference signal configuration information back to the SF, so that the SF can forward the sensing reference signal configuration to other cooperative base stations.

[0081] Step 6: The SF selects the cooperative base stations participating in cooperative sensing.

[0082] As described above, the selection of the cooperative base stations can be based on the comparison of the RSRP values of the uplink signals of the UE measured by the other base stations around the main base station, or based on the location information of the base stations, and based on different sensing service requirements, the cooperative base stations participating in cooperative sensing are selected.

[0083] Step 7: The selected cooperative base stations are sent a cooperative sensing signal cooperative sensing request. The cooperative sensing measurement request can be initiated without sharing the configuration information of the sensing reference signal between the base stations.

[0084] Step 8: The cooperative base stations judge according to their own sensing capabilities, available resources, and service states, to feed back ACK or NACK.

[0085] The cooperative base stations can decide not to configure resources (for example, in the case of no available resources), and subsequently feed back NACK.

[0086] Step 9: The cooperative base stations feed back ACK to the SF to confirm that they can participate in cooperation, or NACK to refuse to participate in cooperation.

[0087] Step 10: In the case where the cooperative base stations report ACK to the SF, the SF sends the resources and configuration information of the sensing reference signal configured by the main base station for the UE to the cooperative base stations, for receiving and demodulating the sensing reference signal.

[0088] Steps 11a, 11b: The main base station and the cooperative base stations receive the sensing reference signal sent by the UE.

[0089] Steps 12a, 12b: The main base station and the cooperative base stations respectively perform sensing measurement on the sensing reference signal.

[0090] Step 13: For semi-persistent and aperiodic SRS, the SF requests the main base station to activate or deactivate the sensing reference signal, and if it is a periodic sensing reference signal, this step is skipped.

[0091] Steps 14a, 14b: The main base station and the cooperative base stations report the sensing measurement results of the sensing reference signal.

[0092] Step 15: The SF fuses the sensing results based on the sensing results of the main base station and the cooperative base stations, and can send the sensing results to the sensing initiator (for example, the UE).

[0093] Cooperative sensing can be divided into three basic modes according to different sharing information: early fusion, mid fusion, and late fusion.

[0094] FIG. 6 shows examples of early fusion, mid fusion, and late fusion according to an embodiment of the present disclosure.

[0095] As shown in the leftmost diagram in FIG. 6, early fusion shares the raw data of each sensing node (including the master base station and the cooperative base station), which can losslessly realize raw data fusion, extract features from the fused raw data through an encoder, and finally obtain the sensing result through a decoder. In the case of early fusion, the performance of cooperative sensing is often the best. However, transmitting raw data consumes a large amount of communication resources, especially when the number of base stations participating in cooperation is large. However, in scenarios with high real-time requirements for sensing, early fusion is difficult to meet the demand.

[0096] As shown in the middle diagram in FIG. 6, mid fusion refers to that each sensing node (including the master base station and the cooperative base station) first processes (for example, encodes) the raw data into intermediate layer features, and then fuses (shares) the intermediate layer features, and finally obtains the final sensing result based on the fused features through a decoder. The intermediate layer features make it easier to recover the original information, and the intermediate layer features are also more flexible and easier to compress to save communication resources.

[0097] As shown in the rightmost diagram in FIG. 6, in late fusion, for each sensing node (including the master base station and the cooperative base station), the raw data is processed (for example, encoded) into intermediate layer features, and independent sensing results are obtained based on the intermediate layer features through a decoder. Then, the sensing results independently generated by each sensing node are fused (shared) to generate the final sensing result. This cooperation method is very economical and efficient in terms of communication cost, but since it is based on the incomplete observation of each sensing node, there is noise or error in the result itself, and the fusion result often loses more than early fusion.

[0098] The present disclosure provides an electronic device 700 in a communication-sensing integrated system according to another embodiment of the present disclosure, comprising: at least one processor; and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the electronic device 700 to perform: based on an uplink reference signal, performing, with a network side device serving the electronic device 700 and a cooperative network side device for cooperatively completing a sensing task, the sensing task for a sensing task related to the electronic device 700.

It should be understood that the various functional units in the electronic device 700 shown in FIG. 7 are only logical modules divided according to the specific functions they implement, and are not intended to limit the specific implementation manner.

[0102] For example, the electronic device 700 can work as a user equipment itself, and can further include external devices such as a memory, a transceiver (not shown), etc. The memory can be used to store programs and related data information required for the electronic device 700 to implement various functions. The transceiver can include one or more communication interfaces to support communication with different devices (e.g., UE, base station, etc.), and the implementation form of the transceiver is not specifically limited here.

[0103] As an example, the electronic device 700 can be a user equipment in the electronic device 400 embodiment; the network-side device in the electronic device 700 embodiment can be the electronic device 400; and the cooperative network-side device in the electronic device 700 embodiment can be a cooperative electronic device in the electronic device 400 embodiment.

In addition, the user equipment can be a wireless communication module (such as an integrated circuit module including a single wafer) mounted on each of the above-described terminals.

[0131] [Application Examples with Respect to Base Station]

[0132] (First Application Example)

[0133] FIG. 12 is a block diagram illustrating a first example of a schematic configuration of an eNB or gNB to which the technology of the present disclosure can be applied. Note that the following description takes an eNB as an example, but the same can be applied to a gNB. The eNB 800 includes one or more antennas 810 and a base station device 820. The base station device 820 and each of the antennas 810 can be connected to each other via an RF cable.

[0134] Each of the antennas 810 includes a single or a plurality of antenna elements such as a plurality of antenna elements included in a multiple-input multiple-output (MIMO) antenna, and functions to transmit and receive a wireless signal for the base station device 820. As illustrated in FIG. 12, the eNB 800 can include a plurality of antennas 810. For example, the plurality of antennas 810 can be compatible with a plurality of frequency bands used by the eNB 800. Although FIG. 12 illustrates an example in which the eNB 800 includes a plurality of antennas 810, the eNB 800 can include a single antenna 810.

[0135] The base station device 820 includes a controller 821, a memory 822, a network interface 823, and a wireless communication interface 825.

[0136] The controller 821 can be, for example, a CPU or a DSP, and operates various functions of a higher layer of the base station device 820. For example, the controller 821 generates data packets from data in a signal processed by the wireless communication interface 825, and transfers the generated packets via the network interface 823. The controller 821 can bundle data from a plurality of baseband processors to generate bundled packets, and transfer the generated bundled packets. The controller 821 can have a logical function of performing control such as radio resource control, radio bearer control, mobility management, admission control, and scheduling. The control can be performed in conjunction with a nearby eNB or a core network node. The memory 822 includes a RAM and a ROM, and stores programs executed by the controller 821 and various types of control data such as a terminal list, transmission power data, and scheduling data.

[0137] The network interface 823 is a communication interface for connecting the base station device 820 to the core network 824. The controller 821 can communicate with a core network node or another eNB via the network interface 823. In this case, the eNB 800 and the core network node or the other eNB can be connected to each other by a logical interface such as an S1 interface and an X2 interface. The network interface 823 can also be a wired communication interface or a wireless communication interface for a wireless backhaul line. If the network interface 823 is a wireless communication interface, the network interface 823 can use a higher frequency band for wireless communication than a frequency band used by the wireless communication interface 825.

[0138] The wireless communication interface 825 supports any cellular communication scheme such as Long Term Evolution (LTE) and LTE-Advanced, and provides wireless connections to terminals located in a cell of the eNB 800 via the antenna 810. The wireless communication interface 825 can generally include, for example, a baseband (BB) processor 826 and an RF circuit 827. The BB processor 826 can perform, for example, encoding / decoding, modulation / demodulation, and multiplexing / demultiplexing, and perform various types of signal processing of layers (e.g., layer 1, medium access control (MAC), radio link control (RLC), and packet data convergence protocol (PDCP)). The BB processor 826 can have a part or all of the logical functions described above instead of the controller 821. The BB processor 826 can be a memory that stores a communication control program, or a module that includes a processor and related circuitry configured to execute the program. Updating the program can cause the functions of the BB processor 826 to change. The module can be a card or a blade that is inserted into a slot of the base station device 820. Alternatively, the module can also be a chip that is mounted on a card or a blade. Meanwhile, the RF circuit 827 can include, for example, a mixer, a filter, and an amplifier, and transmit and receive wireless signals via the antenna 810.

[0139] As illustrated in FIG. 12, the wireless communication interface 825 can include a plurality of BB processors 826. For example, the plurality of BB processors 826 can be compatible with a plurality of frequency bands used by the eNB 800. As illustrated in FIG. 12, the wireless communication interface 825 can include a plurality of RF circuits 827. For example, the plurality of RF circuits 827 can be compatible with a plurality of antenna elements. While FIG. 12 illustrates an example in which the wireless communication interface 825 includes a plurality of BB processors 826 and a plurality of RF circuits 827, the wireless communication interface 825 can also include a single BB processor 826 or a single RF circuit 827.

[0140] The electronic device 400 illustrated in FIG. 4, when implemented as the eNB 800 illustrated in FIG. 12, its transceiver can be implemented by the wireless communication interface 825. At least a part of the functions can also be implemented by the controller 821.

[0143] Each of the antennas 840 includes a single or plural antenna elements (such as plural antenna elements included in a MIMO antenna) and is used for the RRH 860 to transmit and receive a radio signal. As illustrated in FIG. 13, the eNB 830 can include plural antennas 840. For example, the plural antennas 840 can be compatible with plural frequency bands used by the eNB 830. Although FIG. 13 illustrates an example in which the eNB 830 includes plural antennas 840, the eNB 830 can also include a single antenna 840.

[0144] The base station device 850 includes a controller 851, a memory 852, a network interface 853, a wireless communication interface 855, and a connection interface 857.

[0145] The wireless communication interface 855 supports any cellular communication scheme such as LTE and LTE-Advanced, and provides wireless communication to terminals located in a sector corresponding to the RRH 860 via the RRH 860 and the antennas 840. The wireless communication interface 855 can typically include, for example, a BB processor 856. The BB processor 856 is the same as the BB processor 826 described with reference to FIG. 13 except that the BB processor 856 is connected to the RF circuit 864 of the RRH 860 via the connection interface 857. As illustrated in FIG. 13, the wireless communication interface 855 can include plural BB processors 856. For example, the plural BB processors 856 can be compatible with plural frequency bands used by the eNB 830. Although FIG. 13 illustrates an example in which the wireless communication interface 855 includes plural BB processors 856, the wireless communication interface 855 can also include a single BB processor 856.

[0146] The connection interface 857 is an interface for connecting the base station device 850 (the wireless communication interface 855) to the RRH 860. The connection interface 857 can also be a communication module for communication in the above-described high-speed line for connecting the base station device 850 (the wireless communication interface 855) to the RRH 860.

[0147] The RRH 860 includes a connection interface 861 and a wireless communication interface 863.

[0148] The connection interface 861 is an interface for connecting the RRH 860 (wireless communication interface 863) to the base station apparatus 850. The connection interface 861 can also be a communication module for communication in the high-speed line described above.

[0149] The wireless communication interface 863 transmits and receives wireless signals via the antenna 840. The wireless communication interface 863 can generally include, for example, an RF circuit 864. The RF circuit 864 can include, for example, a mixer, a filter, and an amplifier, and transmits and receives wireless signals via the antenna 840. As illustrated in FIG. 13, the wireless communication interface 863 can include a plurality of RF circuits 864. For example, the plurality of RF circuits 864 can support a plurality of antenna elements. While FIG. 13 illustrates an example in which the wireless communication interface 863 includes a plurality of RF circuits 864, the wireless communication interface 863 can also include a single RF circuit 864.

[0150] The electronic device 400 illustrated in FIG. 4, when implemented as the eNB 830 illustrated in FIG. 13, can have its transceiver implemented by the wireless communication interface 855. At least a portion of the functions can also be implemented by the controller 851. For example, the controller 851 can implement a sensing task by a user device with multi-base station uplink cooperation based on an uplink reference signal by performing the functions of the units in the electronic device 400.
