Description

Electronic devices in a communication-sensing integrated system, methods for using a communication-sensing integrated system, and computer-readable storage media This application claims priority to Chinese Patent Application No. 202510015890.1, filed on January 6, 2025, entitled "Electronic device in a communication-sensing integrated system, method for a communication-sensing integrated system and computer-readable storage medium", the entire contents of which are incorporated herein by reference. Technical Field

[0001] This disclosure relates to the field of integrated communication and sensing technology, and more specifically to electronic devices in integrated communication and sensing systems, methods for using integrated communication and sensing systems, and computer-readable storage media. More specifically, it relates to electronic devices and methods in integrated communication and sensing systems for configuring communication reference signals and sensing reference signals. Background Technology

[0002] Integrated Information and Communication (ISAC) is a key technology for 5G-A and 6G communication networks, also known as joint radar communication systems.

[0003] At the 3GPP RANP#102 meeting, research on sensing integration in Rel-19 was proposed. In a sensing integration scenario, the sensing signal transmitter can be a Transmit / Receive Point (TRP) or a User Equipment (UE), the sensing signal receiver can be a TRP or a UE, and the sensing target can be an object with or without connectivity. The sensing receiver receives the radio waves reflected from the sensing target, analyzes the target's shape, position, and velocity, and tracks the target. Figure 1 illustrates the sensing modes of sensing integration. Figure 1 shows six sensing modes for sensing integration, which can include monostatic sensing and bistatic / multistatic sensing. In monostatic sensing, sensing is based on the echo received from the target; in bistatic / multistatic sensing, sensing is based on the target's reflection of the signal. For example, in a dual-sensor scenario, the base station can act as the sender of sensing signals, and the UE can act as the receiver of sensing signals. By having the UE feed back the reception results of the sensing signals, the base station can detect and locate targets within its coverage area, and thus reconstruct the environment.

[0031] Exemplary embodiments of the invention will be described below with reference to the accompanying drawings. For clarity and brevity, not all features of actual implementations are described in the specification. However, it should be understood that many implementation-specific decisions must be made in the development of any such actual embodiment to achieve the developer's specific goals, such as complying with constraints related to the system and business, and these constraints may vary depending on the implementation. Furthermore, it should be understood that while development work can be very complex and time-consuming, such development work is merely a routine task for those skilled in the art who benefit from this disclosure.

[0032] It should also be noted that, in order to avoid obscuring the invention with unnecessary details, only the device structure and / or processing steps closely related to the solution according to the invention are shown in the accompanying drawings, while other details that are not closely related to the invention are omitted.

[0033] This disclosure provides an electronic device 200 in a communication-sensing integrated system according to one embodiment of the 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, through the at least one processor, to cause the electronic device 200 to: configure a communication reference signal for communication and a sensing reference signal for sensing based on a downlink synchronization reference signal, and to enable the communication reference signal and the sensing reference signal to be distinguishable.

[0034] Figure 2 shows an exemplary functional block diagram of an electronic device 200 in a communication-sensing integrated system according to an embodiment of the present disclosure.

[0035] As shown in Figure 2, the electronic device 200 includes: a control unit 201 for control; and a processing unit 203, which can be configured, under the control of the control unit 201, to configure a communication reference signal for communication and a sensing reference signal for sensing based on the downlink synchronization reference signal, and to make the communication reference signal and the sensing reference signal distinguishable.

[0036] The control unit 201 and processing unit 203 can be implemented as one or more processing circuits and at least one memory. The processing circuit can be, for example, a processor or a chip, and the at least one memory can be RAM, ROM, etc. The at least one memory is used to store, for example, computer program code and data required for the processing circuits to perform processing. Furthermore, it should be understood that the various functional units in the electronic device 200 shown in FIG2 are merely logical modules divided according to their specific functions, and are not intended to limit the specific implementation method.

[0037] Electronic device 200 may be located on the base station side or communicatively connected to the base station. For example, electronic device 200 may function as the base station itself and may also include external devices such as memory and transceiver (not shown). Memory may be used to store programs and related data information that electronic device 200 needs to execute to perform various functions. Transceiver may include one or more communication interfaces to support communication with different devices (e.g., UE, base station, etc.), and the specific implementation of the transceiver is not limited here.

[0038] As an example, the base station could be an eNB or a gNB.

[0039] The user equipment (UE) is in the RRC_connected state. For example, after the UE (also known as the terminal) randomly accesses the base station, the electronic device 200 notifies the terminal of the configured communication reference signal and sensing reference signal. After receiving the sensing reference signal, the UE needs to perform measurements and report the measurement results. The electronic device 200 locates or identifies the sensing target by comparing the parameters of the transmitted sensing reference signal with the reported results from the UE. The UE only receives and measures the communication reference signal.

[0040] In the electronic device 200 according to an embodiment of the present disclosure, the communication reference signal and the sensing reference signal can be distinguished, and the user equipment can measure and report only for the sensing reference signal, thereby reducing the overhead and frequency of measurement and reporting by the user equipment; in addition, the electronic device 200 can control between the sensing function and the communication function by adjusting the power and configuration of the communication reference signal and the sensing reference signal.

[0041] As an example, the downlink synchronization reference signal is the synchronization signal block (SSB).

[0042] Downlink signals include, for example, SSB, Channel State Measurement (CSI) signal, and Demodulation Reference Signal (DMRS). Among these three downlink reference signals, the SSB signal is a periodic, full-coverage broadcast reference signal transmitted by the base station. UEs within the base station's coverage area can receive this signal. Therefore, in this application, SSB is selected as the sensing reference signal. In the following text, the sensing reference signal is sometimes referred to as the sensing synchronization reference signal.

[0043] For example, a communication reference signal is a reference signal used only for synchronization, while a sensing reference signal is a synchronization reference signal that has both synchronization and sensing functions.

[0044] As an example, the communication reference signal and the sensing reference signal are distinguished in time. For instance, the communication reference signal and the sensing reference signal are set with different start periods of their respective SSBs, thus distinguishing them in time. Other ways in which the communication reference signal and the sensing reference signal are distinguished in time will also be apparent to those skilled in the art, and will not be elaborated here.

[0045] In the current SSB transmission and reception mechanism, the UE measures different SSB signal beams and selects the transmission beam corresponding to the receiving beam with the strongest SSB beam as the transmission beam for data transmission with the base station. It also informs the base station of the selected optimal downlink beam through implicit time-domain correlation.

[0046] Base stations can configure measurement-related information through the "measConfig" IE in "RRCreconfiguration". The measConfig field configures information such as measObject, reportConfig, measId, and measGapConfig. measObject indicates which time-frequency resources the terminal should measure on, and reportConfig indicates which reference signals the terminal should report and the content of the reports. In 5G NR, the cell configures the terminal's measurement settings, including configuring multiple SSB transmission periods through the IE MeasObjectNR, including local cell synchronization signals, neighboring cell synchronization signals, synchronization signals discovered by IAB nodes, and SSB measurement time configurations defined for NTN (Non-Terrestrial Network) applications.

[0047] When using SSB as a sensing beam, the base station needs to configure SSB for the UE, and the UE needs to report the measurement results after measurement. The base station can locate or identify the sensing target by comparing the parameters of the transmitted SSB with the reported results of the UE.

[0048] Figure 3 is a schematic diagram illustrating inter-cell sensing and reporting according to an embodiment of the present disclosure.

[0049] From the terminal's perspective, as shown in Figure 3, if the UE is located at the edge of the coverage area of ​​the serving cell served by the electronic device 200, the terminal is very likely to receive sensing reflection signals from neighboring cells. The terminal can report the measurement results of these sensing signals to the electronic device 200 to help the base station of the neighboring cell locate and identify sensing targets within its coverage area. In Figure 3, SSB2 represents the sensing reference signal of the serving cell, and SSB1 represents the sensing reference signal of the neighboring cell.

[0050] As an example, processing unit 203 can be configured to notify user equipment within the serving cell served by electronic device 200 of the configuration of the sensing reference signal of the serving cell and the configuration of the sensing reference signal of neighboring cells adjacent to the serving cell. Thus, user equipment can report measurement results of the sensing reference signals of neighboring cells to electronic device 200, thereby assisting the base stations of neighboring cells in locating and identifying sensing targets within their coverage area.

[0051] As an example, processing unit 203 can be configured to add SSB measurement timing configuration (SMTC) of the serving cell's sensed reference signal and SMTC of the neighboring cell's sensed reference signal to the measurement object signaling of Radio Resource Control (RRC) for notification purposes.

[0052] In 38.331MeasObjectNR, there are currently four configurations: SMTC1, SMTC2, SMTC3, and SMTC4. Each configuration configures synchronization signals for different scenarios. SMTC1 configures synchronization signals for the local cell, SMTC2 configures synchronization signals for neighboring cells (for mobility measurement), SMTC3 configures synchronization signals for the discovery of IAB nodes (Integrated Access and Backhaul Nodes), and SMTC4 configures signals for NTN scenarios. In this application, SMTC5 (configuration for the serving cell's perceived synchronization reference signal) and SMTC6 (configuration for the neighboring cell's perceived synchronization reference signal) are added.

[0053] Table 1 below shows the configuration of MeasObjectNR according to this embodiment.

[0054] As an example, processing unit 203 can be configured to receive reports from user equipment regarding the sensing reference signal of the serving cell and / or the sensing reference signal of neighboring cells. The user equipment reports to electronic equipment 200 as soon as it receives the sensing reference signal of the serving cell and / or the sensing reference signal of a neighboring cell. This is a non-event-triggered reporting mechanism; in this mechanism, the terminal reports the measurement results as soon as it receives the sensing reference signal of the serving cell or the sensing reference signal of a neighboring cell.

[0055] As an example, processing unit 203 can be configured to receive reports from user equipment regarding the sensing reference signal of the serving cell and / or the sensing reference signal of neighboring cells. The user equipment performs the report when the received signal strength of the sensing reference signal of the serving cell is greater than a first predetermined threshold and / or the received signal strength of the sensing reference signal of the neighboring cell is greater than a second predetermined threshold. This method is event-based measurement reporting. The reporting event type, `reportType`, is defined as the received signal strength of the sensing reference signal of the current serving cell being higher than the threshold and / or the received signal strength of the sensing reference signal of the neighboring cell being higher than the threshold. By setting the reporting event type, it is possible to avoid the terminal reporting even when the received quality strength of the sensing reference signal is very weak, thereby avoiding the occupation of uplink resources. If the received signal strength of the sensing reference signal is low, it provides less sensing information; by appropriately adjusting the threshold setting, a flexible balance can be struck between sensing accuracy and resource consumption.

[0056] The first predetermined threshold and the second predetermined threshold may be equal or unequal. Those skilled in the art can preset the first predetermined threshold and the second predetermined threshold based on experience or application scenarios.

[0057] As an example, processing unit 203 can be configured to add the following events as reporting trigger events in the RRC report configuration signaling: the received signal strength of the serving cell's sensing reference signal is greater than a first predetermined threshold and / or the received signal strength of the neighboring cell's sensing reference signal is greater than a second predetermined threshold. For example, electronic device 200 configures measurement events and specific parameters through the ReportConfigNR signaling in RRC reconfiguration, adding event A7 (the received signal strength of the serving cell's sensing reference signal is greater than the first predetermined threshold) and event A8 (the received signal strength of the neighboring cell's sensing reference signal is greater than the second predetermined threshold) as trigger events for sensing measurement reporting.

[0058] To provide sensing services, the existing reportConfig content needs to be modified to report sensing-related measurement results. Simultaneously, the SSB index needs to be correlated with the measurement results. The electronic device 200 needs to combine the transmitted beam of the SSB with its reflected beam after passing through the sensing target to infer the target's position and shape. Chapter 5.5.1 of TS38.331 specifies the information that needs to be reported after measuring the SSB, including reporting measurement results based on each SS / PBCH block, reporting measurement results based on the cell's SS / PBCH (Synchronization Signal / Physical Broadcast Channel) blocks, and the SS / PBCH block index. This reported information is insufficient to provide information about the sensing target. In this application, the reporting of sensing information measured at the UE end is added.

[0059] As an example, the processing unit 203 can be configured to report content related to the sensed reference signal in the report via RRC, wherein the report content includes the ID of the beam carrying the sensed reference signal, the measured reference signal received power, time delay, and Doppler frequency shift of the sensed reference signal.

[0060] As an example, the reported information also includes the incident angle of the beam at the user equipment end.

[0061] Table 2 shows examples of modifications to Chapter 5.5.1 of TS38.331 according to embodiments of this disclosure.

[0062] As shown in Table 2, compared to the existing Chapter 5.5.1 of TS38.331, sensing information has been added. As mentioned above, sensing information may include the reference signal received power, time delay, Doppler frequency shift, beam incidence angle direction, etc., of the sensing reference signal measured at the UE.

[0063] This disclosure also provides an electronic device 400 in a communication-sensing integrated system according to another embodiment of this disclosure. The electronic device 400 includes at least one processor and at least one memory, the at least one memory including computer program code, wherein the at least one memory and the computer program code are configured, via the at least one processor, to cause the electronic device 400 to perform: multiplexing a downlink synchronization reference signal as both a communication reference signal for communication and a sensing reference signal for sensing.

[0064] Figure 4 shows an exemplary functional block diagram of an electronic device 400 in a communication-sensing integrated system according to another embodiment of the present disclosure.

[0065] As shown in Figure 4, the electronic device 400 includes: a control unit 401, which performs control; and a processing unit 403, which, under the control of the control unit 401, multiplexes the downlink synchronization reference signal as both a communication reference signal for communication and a sensing reference signal for sensing.

[0066] The control unit 401 and processing unit 403 can be implemented as one or more processing circuits and at least one memory. The processing circuit can be, for example, a processor or a chip, and the at least one memory can be RAM, ROM, etc. The at least one memory is used to store, for example, computer program code and data required for the processing circuits to perform processing. Furthermore, it should be understood that the various functional units in the electronic device 400 shown in FIG. 4 are merely logical modules divided according to their specific functions, and are not intended to limit the specific implementation method.

[0067] Electronic device 400 may be located on the base station side or communicatively connected to the base station. For example, electronic device 400 may function as the base station itself and may also include external devices such as memory and transceiver (not shown). Memory may be used to store programs and related data information that electronic device 400 needs to execute to perform various functions. Transceiver may include one or more communication interfaces to support communication with different devices (e.g., UE, base station, etc.), and the implementation of transceiver is not specifically limited here.

[0068] As an example, the base station could be an eNB or a gNB.

[0069] In the electronic device 400 according to an embodiment of the present disclosure, the existing downlink synchronization reference signal configuration mechanism is directly reused without distinguishing between communication reference signals and sensing reference signals, so this method is relatively simple.

[0070] The user equipment (UE) is in the RRC_connected state. The downlink synchronization reference signal is multiplexed as a sensing reference signal. While performing beam alignment, the UE reports its reception status of the downlink synchronization reference signal (i.e., reports the UE's reception status of the sensing reference signal to the electronic device 400). After receiving the report from the UE, the electronic device 400 analyzes whether the downlink synchronization reference signal is used for communication or sensing.

[0071] As an example, the downlink synchronization reference signal is the synchronization signal block SSB.

[0072] Referring to Table 1 above, SMTC2 is a configuration for neighboring cell synchronization signals, meaning the base station notifies the user equipment of the SSB of neighboring cells. In the electronic device 400 according to embodiments of this disclosure, this is equivalent to the electronic device 400 notifying the user equipment of the sensing reference signals of neighboring cells.

[0073] As an example, processing unit 403 can be configured to receive reports from user equipment regarding the sensing reference signal of the serving cell served by electronic equipment 400 and / or the sensing reference signal of neighboring cells adjacent to the serving cell. The user equipment reports to electronic equipment 400 whenever it receives the sensing reference signal of the serving cell and / or the sensing reference signal of a neighboring cell. This is a non-event-triggered reporting mechanism; in this mechanism, the terminal reports the measurement results as soon as it receives the sensing reference signal of the serving cell or the sensing reference signal of a neighboring cell.

[0074] As an example, processing unit 403 can be configured to receive reports from user equipment regarding the sensing reference signal of the serving cell served by electronic equipment 400 and / or the sensing reference signal of neighboring cells adjacent to the serving cell. The user equipment performs the report when the received signal strength of the sensing reference signal of the serving cell is greater than a third predetermined threshold and / or the received signal strength of the sensing reference signal of the neighboring cell is greater than a fourth predetermined threshold. This method is event-based measurement reporting. The reporting event type, `reportType`, is defined as the received signal strength of the sensing reference signal of the current serving cell being higher than the threshold and / or the received signal strength of the sensing reference signal of the neighboring cell being higher than the threshold. By setting the reporting event type, it is possible to avoid the terminal reporting even when the received quality strength of the sensing reference signal is very weak, thereby avoiding the occupation of uplink resources. If the received signal strength of the sensing reference signal is low, it provides less sensing information; by appropriately adjusting the threshold setting, a flexible balance can be struck between sensing accuracy and resource consumption.

[0075] The third and fourth predetermined thresholds may be equal or unequal. Those skilled in the art can pre-set the third and fourth predetermined thresholds based on experience or application scenarios.

[0076] As an example, processing unit 403 can be configured to add the following events as reporting trigger events in the RRC report configuration signaling: the received signal strength of the serving cell's sensed reference signal is greater than a third predetermined threshold and / or the received signal strength of the neighboring cell's sensed reference signal is greater than a fourth predetermined threshold. For example, electronic device 400 configures measurement events and specific parameters through the ReportConfigNR signaling in RRC reconfiguration, adding event A7 (the received signal strength of the serving cell's sensed reference signal is greater than a third predetermined threshold) and event A8 (the received signal strength of the neighboring cell's sensed reference signal is greater than a fourth predetermined threshold) as trigger events for sense measurement reporting.

[0077] As an example, the processing unit 403 can be configured to report content related to the sensed reference signal in the report via RRC, wherein the report content includes the ID of the beam carrying the sensed reference signal, the measured reference signal received power, time delay, and Doppler frequency shift of the sensed reference signal.

[0078] The reported information also includes the incident angle of the beam at the user equipment end.

[0079] The description of the reported content can be found in Table 2 of the embodiment of electronic device 200, and will not be repeated here.

[0080] This disclosure provides an electronic device 500 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, through the at least one processor, to cause the electronic device 500 to perform: configuring communication reference signals for communication and sensing reference signals for sensing by a network-side device serving the electronic device 500, wherein the network-side device configures the communication reference signals and sensing reference signals respectively based on a downlink synchronization reference signal, and enables the communication reference signals and sensing reference signals to be distinguishable.

[0081] Figure 5 shows an exemplary functional block diagram of an electronic device 500 in a communication-sensing integrated system according to another embodiment of the present disclosure.

[0082] As shown in Figure 5, the electronic device 500 includes: a control unit 501 for control; and a processing unit 503 configured, under the control of the control unit 501, to configure communication reference signals for communication and sensing reference signals for sensing by a network-side device providing services to the electronic device 500, wherein the network-side device configures the communication reference signals and sensing reference signals based on a downlink synchronization reference signal, and makes the communication reference signals and sensing reference signals distinguishable.

[0083] The control unit 501 and processing unit 503 can be implemented as one or more processing circuits and at least one memory. The processing circuit can be, for example, a processor or a chip, and the at least one memory can be RAM, ROM, etc. The at least one memory is used to store, for example, computer program code and data required for the processing circuits to perform processing. Furthermore, it should be understood that the various functional units in the electronic device 500 shown in FIG. 5 are merely logical modules divided according to their specific functions, and are not intended to limit the specific implementation method.

[0084] For example, electronic device 500 can function as a user equipment itself and may also include external devices such as memory and transceiver (not shown). The memory can be used to store programs and related data information that electronic device 500 needs to execute to perform various functions. The transceiver may include one or more communication interfaces to support communication with different devices (e.g., UE, base station, etc.), and there is no specific limitation on the implementation of the transceiver.

[0085] Electronic device 500 is in the RRC_connected state. For example, after electronic device 500 randomly connects to a network-side device, the network-side device notifies electronic device 500 of the configured communication reference signal and sensing reference signal. After receiving the sensing reference signal, electronic device 500 needs to perform measurements and report the measurement results. The network-side device locates or identifies the sensing target by comparing the parameters of the transmitted sensing reference signal with the reported results of electronic device 500.

[0086] In the electronic device 500 according to the embodiments of the present disclosure, since the communication reference signal and the sensing reference signal can be distinguished, the electronic device 500 can measure and report only for the sensing reference signal, thereby reducing the overhead and frequency of measurement and reporting; in addition, the power and configuration of the communication reference signal and the sensing reference signal can be adjusted to control between the sensing function and the communication function.

[0087] As an example, the downlink synchronization reference signal is the synchronization signal block (SSB).

[0088] For example, a communication reference signal is a reference signal used only for synchronization, while a sensing reference signal is a synchronization reference signal that has both synchronization and sensing functions.

[0089] As an example, the communication reference signal and the sensing reference signal are distinguished in time. For instance, the communication reference signal and the sensing reference signal are set with different start periods of their respective SSBs, thus distinguishing them in time. Other ways in which the communication reference signal and the sensing reference signal are distinguished in time will also be apparent to those skilled in the art, and will not be elaborated here.

[0090] As an example, processing unit 503 can be configured to receive notifications from network-side equipment regarding the configuration of the sensing reference signal of the serving cell and the configuration of the sensing reference signal of neighboring cells adjacent to the serving cell. Thus, electronic equipment 500 can report measurement results of the sensing reference signals of neighboring cells to the network-side equipment to assist the base station of the neighboring cells in locating and identifying sensing targets within its coverage area.

[0091] Specifically, in the measurement object signaling of Radio Resource Control (RRC), the SSB Measurement Timing Configuration (SMTC) of the Serving Cell's Sensing Reference Signal and the SMTC of the Sensing Reference Signal of Neighboring Cells are added for notification purposes.

[0092] The description of the newly added SMTC can be found in Table 1 of the embodiment of the electronic device 200, and will not be repeated here.

[0093] As an example, processing unit 503 can be configured to report information about the sensing reference signal of the serving cell and / or the sensing reference signal of neighboring cells to network-side devices. The electronic device 500 reports this information whenever it receives the sensing reference signal of the serving cell and / or the sensing reference signal of a neighboring cell. This method is non-event-triggered; in this reporting mechanism, the electronic device 500 reports the measurement results whenever it receives the sensing reference signal of the serving cell or the sensing reference signal of a neighboring cell.

[0094] As an example, processing unit 503 can be configured to report information about the sensing reference signal of the serving cell and / or the sensing reference signal of neighboring cells to the network-side device. Reporting occurs when the received signal strength of the sensing reference signal of the serving cell is greater than a first predetermined threshold and / or the received signal strength of the sensing reference signal of the neighboring cell is greater than a second predetermined threshold. This method is event-based measurement reporting. The reporting event type, `reportType`, is defined as the received signal strength of the sensing reference signal of the current serving cell being higher than the threshold and / or the received signal strength of the sensing reference signal of the neighboring cell being higher than the threshold. By setting the reporting event type, the electronic device 500 can avoid reporting even when the received quality strength of the sensing reference signal is very weak, thereby avoiding the occupation of uplink resources. If the received signal strength of the sensing reference signal is low, it provides less sensing information; by appropriately adjusting the threshold setting, a flexible balance can be struck between sensing accuracy and resource consumption.

[0095] In the RRC reporting configuration signaling, the following events are added as reporting trigger events: the received signal strength of the sensing reference signal of the serving cell is greater than a first predetermined threshold and / or the received signal strength of the sensing reference signal of a neighboring cell is greater than a second predetermined threshold.

[0096] The reporting content related to the sensing reference signal is configured through RRC. The reporting content includes the ID of the beam carrying the sensing reference signal, the measured reference signal received power, time delay, and Doppler frequency shift of the sensing reference signal.

[0097] The reported information also includes the incident angle of the beam at the 500 end of the electronic device.

[0098] Electronic device 500 can correspond to the user equipment in the embodiment of electronic device 200, and network-side equipment in the embodiment of electronic device 500 can correspond to electronic device 200. For a detailed description of electronic device 500, please refer to the description of the user equipment in the embodiment of electronic device 200, which will not be repeated here.

[0099] This disclosure also provides an electronic device 600 in a communication-sensing integrated system according to yet another embodiment of this disclosure. The electronic device 600 includes at least one processor and at least one memory, the at least one memory including computer program code, wherein the at least one memory and the computer program code are configured, via the at least one processor, to cause the electronic device 600 to perform: configuring, by a network-side device serving the electronic device 600, communication reference signals for communication and sensing reference signals for sensing, wherein the network-side device multiplexes a downlink synchronization reference signal as both the communication reference signal and the sensing reference signal.

[0100] Figure 6 shows an exemplary functional block diagram of an electronic device 600 in a communication-sensing integrated system according to yet another embodiment of the present disclosure.

[0101] As shown in Figure 6, the electronic device 600 includes: a control unit 601, which performs control; and a communication unit 603, which, under the control of the control unit 601, configures communication reference signals for communication and sensing reference signals for sensing by a network-side device that provides services to the electronic device 600. The network-side device multiplexes the downlink synchronization reference signal as both the communication reference signal and the sensing reference signal.

[0102] The control unit 601 and communication unit 603 can be implemented as one or more processing circuits and at least one memory. The processing circuit can be, for example, a processor or chip, and the at least one memory can be RAM, ROM, etc. The at least one memory is used to store, for example, computer program code and data required for the processing circuits to perform processing. Furthermore, it should be understood that the various functional units in the electronic device 600 shown in FIG. 6 are merely logical modules divided according to their specific functions, and are not intended to limit the specific implementation method.

[0103] For example, electronic device 600 can function as a user equipment itself and may also include external devices such as memory and transceiver (not shown). The memory can be used to store programs and related data information that electronic device 600 needs to execute to perform various functions. The transceiver may include one or more communication interfaces to support communication with different devices (e.g., UE, base station, etc.), and the specific implementation of the transceiver is not limited here.

[0104] In the electronic device 600 according to an embodiment of the present disclosure, since the existing downlink synchronization reference signal configuration mechanism is directly reused without distinguishing between communication reference signals and sensing reference signals, the method is relatively simple.

[0105] Electronic device 600 is in the RRC_connected state. The downlink synchronization reference signal is multiplexed as a sensing reference signal. While performing beam alignment, electronic device 600 feeds back the reception status of the downlink synchronization reference signal (i.e., reports the reception status of the sensing reference signal to the network-side device). After receiving the reported content, the network-side device analyzes whether the downlink synchronization reference signal is used for communication or for sensing.

[0106] As an example, the downlink synchronization reference signal is the synchronization signal block SSB.

[0107] As an example, processing unit 603 can be configured to report information about the sensing reference signal of the serving cell served by the network-side device and / or the sensing reference signal of neighboring cells adjacent to the serving cell to the network-side device. The electronic device 600 reports this information whenever it receives the sensing reference signal of the serving cell and / or the sensing reference signal of a neighboring cell. This method is non-event-triggered; in this reporting mechanism, the electronic device 600 reports the measurement results whenever it receives the sensing reference signal of the serving cell or the sensing reference signal of a neighboring cell.

[0108] As an example, processing unit 603 can be configured to report information about the sensing reference signal of the serving cell served by the network-side device and / or the sensing reference signal of neighboring cells adjacent to the serving cell to the network-side device. Reporting occurs when the received signal strength of the sensing reference signal of the serving cell is greater than a third predetermined threshold and / or the received signal strength of the sensing reference signal of the neighboring cell is greater than a fourth predetermined threshold. This method is event-based measurement reporting. The reporting event type, `reportType`, is defined as the received signal strength of the sensing reference signal of the current serving cell being higher than the threshold and / or the received signal strength of the sensing reference signal of the neighboring cell being higher than the threshold. By setting the reporting event type, the electronic device 600 can avoid reporting even when the received quality strength of the sensing reference signal is very weak, thereby avoiding the occupation of uplink resources. If the received signal strength of the sensing reference signal is low, it provides less sensing information; by appropriately adjusting the threshold setting, a flexible balance can be struck between sensing accuracy and resource consumption.

[0109] As an example, the processing unit 603 can be configured to add the following events as reporting trigger events in the RRC report configuration signaling: the received signal strength of the sensing reference signal of the serving cell is greater than a third predetermined threshold and / or the received signal strength of the sensing reference signal of the neighboring cell is greater than a fourth predetermined threshold.

[0110] As an example, the processing unit 603 can be configured to report content related to the sensed reference signal in the report via RRC, wherein the report content includes the ID of the beam carrying the sensed reference signal, the measured reference signal received power, time delay, and Doppler frequency shift of the sensed reference signal.

[0111] The report also includes the incident angle of the beam at the 600 end of the electronic device.

[0122] The technology disclosed herein can be applied to a variety of products.

[0123] Electronic devices 200 and 400 can be located on the base station side or connected to the base station. The base station can be implemented as any type of evolved NodeB (eNB) or gNB (5G base station). eNBs include, for example, macro eNBs and small eNBs. Small eNBs can be eNBs covering cells smaller than macro cells, such as pico eNBs, micro eNBs, and femtocell eNBs. A similar situation can occur with gNBs. Alternatively, the base station can be implemented as any other type of base station, such as a NodeB and a Base Transceiver Station (BTS). A base station can include: a main body configured to control wireless communication (also called base station equipment); and one or more remote radio heads (RRHs) located in a different location from the main body. Furthermore, various types of electronic devices can operate as base stations by temporarily or semi-persistently performing base station functions.

[0124] Electronic devices 500 and 600 can be located on the user equipment side or connected to the user equipment. The user equipment can be implemented as a mobile terminal (such as a smartphone, tablet PC, laptop PC, portable gaming terminal, portable / dongle-type mobile router, and digital camera device) or an in-vehicle terminal (such as a car navigation device). The user equipment can also be implemented as a terminal performing machine-to-machine (M2M) communication (also known as a machine-type communication (MTC) terminal). Furthermore, the user equipment can be a wireless communication module (such as an integrated circuit module comprising a single chip) installed on each of the aforementioned terminals.

[0125] [Application examples of base stations]

[0126] (First application example)

[0127] Figure 11 is a block diagram illustrating a first example of a schematic configuration of an eNB or gNB to which the technologies of this disclosure can be applied. Note that the following description uses an eNB as an example, but it can also 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 antenna 810 can be connected to each other via RF cables.

[0128] Each of the antennas 810 includes one or more antenna elements (such as multiple antenna elements included in a multiple-input multiple-output (MIMO) antenna) and is used by the base station device 820 to transmit and receive wireless signals. As shown in Figure 11, the eNB 800 may include multiple antennas 810. For example, multiple antennas 810 may be compatible with multiple frequency bands used by the eNB 800. Although Figure 11 shows an example in which the eNB 800 includes multiple antennas 810, the eNB 800 may also include a single antenna 810.

[0129] The base station equipment 820 includes a controller 821, a memory 822, a network interface 823, and a wireless communication interface 825.

[0130] The controller 821 can be, for example, a CPU or a DSP, and operates various higher-level functions of the base station equipment 820. For example, the controller 821 generates data packets based on data in signals processed by the wireless communication interface 825, and transmits the generated packets via the network interface 823. The controller 821 can bundle data from multiple baseband processors to generate bundled packets and transmit the generated bundled packets. The controller 821 may have logical functions that perform controls such as radio resource control, radio bearer control, mobility management, admission control, and scheduling. This control can be performed in conjunction with nearby eNBs or core network nodes. The memory 822 includes RAM and ROM, and stores programs executed by the controller 821 and various types of control data (such as terminal lists, transmission power data, and scheduling data).

[0131] Network interface 823 is a communication interface used to connect base station equipment 820 to core network 824. Controller 821 can communicate with core network nodes or other eNBs via network interface 823. In this case, eNB 800 and core network nodes or other eNBs can be connected to each other through logical interfaces (such as S1 and X2 interfaces). Network interface 823 can also be a wired communication interface or a wireless communication interface for wireless backhaul. If network interface 823 is a wireless communication interface, it can use a higher frequency band for wireless communication compared to the frequency band used by wireless communication interface 825.

[0132] The wireless communication interface 825 supports any cellular communication scheme (such as LTE and LTE-Advanced) and provides wireless connectivity to terminals located in the cell of eNB 800 via antenna 810. The wireless communication interface 825 typically includes, for example, a baseband (BB) processor 826 and RF circuitry 827. The BB processor 826 can perform, for example, encoding / decoding, modulation / demodulation, and multiplexing / demultiplexing, and performs various types of signal processing at layers (e.g., Layer 1, Medium Access Control (MAC), Radio Link Control (RLC), and Packet Data Convergence Protocol (PDCP)). Instead of controller 821, the BB processor 826 can have some or all of the above-described logical functions. The BB processor 826 can be a memory storing communication control programs, or a module including a processor and associated circuitry configured to execute programs. Update programs can change the functionality of the BB processor 826. The module can be a card or blade inserted into a slot in base station equipment 820. Alternatively, the module can also be a chip mounted on a card or blade. Meanwhile, the RF circuit 827 may include, for example, a mixer, a filter, and an amplifier, and transmits and receives wireless signals via the antenna 810.

[0133] As shown in Figure 11, the wireless communication interface 825 may include multiple BB processors 826. For example, the multiple BB processors 826 may be compatible with multiple frequency bands used by the eNB 800. As shown in Figure 11, the wireless communication interface 825 may include multiple RF circuits 827. For example, the multiple RF circuits 827 may be compatible with multiple antenna elements. Although Figure 11 shows an example in which the wireless communication interface 825 includes multiple BB processors 826 and multiple RF circuits 827, the wireless communication interface 825 may also include a single BB processor 826 or a single RF circuit 827.

[0134] When the electronic device 200 shown in Figure 2 and the electronic device 400 shown in Figure 4 are implemented as the eNB 800 shown in Figure 11, their transceivers can be implemented by the wireless communication interface 825. At least a portion of the functionality can also be implemented by the controller 821. For example, the controller 821 can configure communication reference signals and sensing reference signals by executing the functions of the units in electronic devices 200 and 400.

[0135] (Second application example)

[0136] Figure 12 is a block diagram illustrating a second example of a schematic configuration of an eNB or gNB to which the technologies of this disclosure can be applied. Note that, similarly, the following description uses an eNB as an example, but it can also be applied to a gNB. The eNB 830 includes one or more antennas 840, a base station device 850, and an RRH 860. The RRH 860 and each antenna 840 can be connected to each other via RF cables. The base station device 850 and the RRH 860 can be connected to each other via high-speed lines such as fiber optic cables.

[0137] Each of the antennas 840 includes one or more antenna elements (such as multiple antenna elements included in a MIMO antenna) and is used by the RRH 860 to transmit and receive wireless signals. As shown in Figure 12, the eNB 830 may include multiple antennas 840. For example, multiple antennas 840 may be compatible with multiple frequency bands used by the eNB 830. Although Figure 12 shows an example in which the eNB 830 includes multiple antennas 840, the eNB 830 may also include a single antenna 840.

[0138] 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. The controller 851, memory 852, and network interface 853 are the same as the controller 821, memory 822, and network interface 823 described with reference to FIG12.

[0139] The wireless communication interface 855 supports any cellular communication scheme (such as LTE and LTE-Advanced) and provides wireless communication to terminals located in the sector corresponding to the RRH 860 via the RRH 860 and antenna 840. The wireless communication interface 855 may typically include, for example, a BB processor 856. The BB processor 856 is identical to the BB processor 826 described with reference to FIG12, except that it is connected to the RF circuitry 864 of the RRH 860 via a connection interface 857. As shown in FIG12, the wireless communication interface 855 may include multiple BB processors 856. For example, multiple BB processors 856 may be compatible with multiple frequency bands used by the eNB 830. Although FIG12 shows an example in which the wireless communication interface 855 includes multiple BB processors 856, the wireless communication interface 855 may also include a single BB processor 856.

[0140] Connection interface 857 is an interface for connecting base station device 850 (wireless communication interface 855) to RRH 860. Connection interface 857 can also be a communication module for connecting base station device 850 (wireless communication interface 855) to the aforementioned high-speed line of RRH 860.

[0141] The RRH 860 includes a connectivity interface 861 and a wireless communication interface 863.

[0142] Connection interface 861 is an interface for connecting RRH 860 (wireless communication interface 863) to base station equipment 850. Connection interface 861 can also be a communication module for communication in the aforementioned high-speed line.

[0143] Wireless communication interface 863 transmits and receives wireless signals via antenna 840. Wireless communication interface 863 typically includes, for example, RF circuitry 864. RF circuitry 864 may include, for example, mixers, filters, and amplifiers, and transmits and receives wireless signals via antenna 840. As shown in FIG12, wireless communication interface 863 may include multiple RF circuits 864. For example, multiple RF circuits 864 may support multiple antenna elements. Although FIG12 shows an example in which wireless communication interface 863 includes multiple RF circuits 864, wireless communication interface 863 may also include a single RF circuit 864.

[0144] When the electronic device 200 shown in Figure 2 and the electronic device 400 shown in Figure 4 are implemented as the eNB 830 shown in Figure 12, their transceivers can be implemented by the wireless communication interface 855. At least a portion of the functionality can also be implemented by the controller 851. For example, the controller 851 can configure communication reference signals and sensing reference signals by executing the functions of the units in electronic devices 200 and 400.

[0145] [Application examples related to user equipment]

The speaker 911 converts the audio signal output from the smartphone 900 into sound.

[0150] The wireless communication interface 912 supports any cellular communication scheme (such as LTE and LTE-Advanced) and performs wireless communication. The wireless communication interface 912 typically includes, for example, a BB processor 913 and RF circuitry 914. The BB processor 913 can perform, for example, encoding / decoding, modulation / demodulation, and multiplexing / demultiplexing, and performs various types of signal processing for wireless communication. Meanwhile, the RF circuitry 914 can include, for example, mixers, filters, and amplifiers, and transmits and receives wireless signals via antenna 916. Note that although the figure shows a scenario where one RF link is connected to one antenna, this is only illustrative; scenarios where one RF link is connected to multiple antennas via multiple phase shifters are also included. The wireless communication interface 912 can be a chip module on which the BB processor 913 and RF circuitry 914 are integrated. As shown in Figure 13, the wireless communication interface 912 can include multiple BB processors 913 and multiple RF circuits 914. Although Figure 13 shows an example where the wireless communication interface 912 includes multiple BB processors 913 and multiple RF circuits 914, the wireless communication interface 912 can also include a single BB processor 913 or a single RF circuitry 914.

[0151] In addition to cellular communication schemes, the wireless communication interface 912 can support other types of wireless communication schemes, such as short-range wireless communication schemes, near-field communication schemes, and wireless local area network (LAN) schemes. In this case, the wireless communication interface 912 may include a BB processor 913 and RF circuitry 914 for each wireless communication scheme.

[0152] Each of the antenna switches 915 switches the connection destination of the antenna 916 among multiple circuits (e.g., circuits for different wireless communication schemes) included in the wireless communication interface 912.

[0153] Each of the antennas 916 includes one or more antenna elements (such as multiple antenna elements included in a MIMO antenna) and is used for transmitting and receiving wireless signals through the wireless communication interface 912. As shown in Figure 13, the smartphone 900 may include multiple antennas 916. Although Figure 13 shows an example in which the smartphone 900 includes multiple antennas 916, the smartphone 900 may also include a single antenna 916.

[0154] Furthermore, the smartphone 900 may include an antenna 916 for each wireless communication scheme. In this case, the antenna switch 915 can be omitted from the configuration of the smartphone 900.

[0155] Bus 917 connects processor 901, memory 902, storage device 903, external connection interface 904, camera device 906, sensor 907, microphone 908, input device 909, display device 910, speaker 911, wireless communication interface 912, and auxiliary controller 919 to each other. Battery 918 supplies power to the various blocks of smartphone 900 shown in FIG. 13 via feeders, which are partially shown as dashed lines in the figure. Auxiliary controller 919 operates the minimum necessary functions of smartphone 900, for example, in sleep mode.

[0156] When electronic devices 500 (as shown in FIG. 5) and 600 (as shown in FIG. 6) are respectively implemented as smartphones on the user equipment side, such as smartphone 900 (as shown in FIG. 13), the transceivers of electronic devices 500 and 600 can be implemented by wireless communication interface 912. At least a portion of the functions can also be implemented by processor 901 or auxiliary controller 919. For example, processor 901 or auxiliary controller 919 configures communication reference signals and sensing reference signals by network-side devices by executing the functions of the units in electronic devices 500 and 600.
