TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of communication and sensing integration, in particular to an electronic device in a communication and sensing integrated system, a method for a communication and sensing integrated system, and a computer-readable storage medium. More particularly, it relates to an electronic device and a method in a communication and sensing integrated system for joint control of a reconfigurable intelligent surface through a communication task and a sensing task, while guaranteeing the quality of service of communication and sensing services. BACKGROUND

[0002] Integrated sensing and communication (ISAC) is a key technology for 5G-A and 6G communication networks, also known as joint radar communication systems. 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 entire network-covered physical world can be modeled, and sensing-assisted communication and communication-assisted sensing can be provided. Integrated sensing and communication is an emerging technology that combines wireless communication and sensing capabilities. It achieves resource sharing, such as spectrum, hardware, and signal processing platforms, by integrating radar sensing and wireless communication. ISAC technology has integrated gains in optimizing resource utilization and coordination performance, and integrates sensing and communication into the signaling level, leading to a revolution in Internet of Things architecture. However, ISAC technology also faces some research problems and challenges. First, ISAC technology needs to address the problem of resource sharing and allocation. Since sensing and communication share the same resources, such as spectrum and hardware platforms, how to achieve effective resource allocation and management becomes an important research problem. Second, ISAC technology needs to address the interference problem between sensing and communication. Since sensing and communication operate in the same frequency band, interference between them can affect system performance. Therefore, how to achieve effective interference management and suppression between sensing and communication becomes a key challenge. In addition, ISAC technology also faces challenges in security and privacy protection. Since sensing and communication involve the transmission and processing of sensitive information, how to ensure the security and privacy protection of data becomes an important research direction.

[0003] Reconfigurable intelligent surface (RIS) is a new type of physical dimension wireless transmission technology, which has the advantages of low cost, low energy consumption, programmable and easy deployment. However, the performance of RIS in the actual network may be severely limited by network overhead. In the prior art, RIS is mainly used to enhance the communication signal in the dead angle or severely attenuated area, and improve the communication coverage. In the prior art, the detection probability of cognitive radio primary user activity is improved by using intelligent reflecting surface. In the prior art, a dynamic spectrum anti-jamming system based on intelligent reflecting surface is proposed, which realizes the 2ASK modulation system of intelligent reflecting surface, uses Dyna-Q algorithm, and effectively avoids malicious interference in the environment. In the prior art, a method for determining the reference signal configuration of the intelligent reflecting surface is proposed. SUMMARY

[0026] In the following, exemplary embodiments of the present application will be described with reference to the accompanying drawings. In the description, not all of the features of the actual implementation can be described in order to conciseness and clarity. However, it should be appreciated that in the development of any such actual implementation numerous implementation-specific decisions must be made in order to achieve the developer's specific goals, such as compliance with system- and business-related constraints, which can vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.

[0027] It is also necessary to note that, in order not to obscure the present application with unnecessary details, only the device structures and / or processing steps closely related to the solution according to the present application are shown in the drawings, while other details that are not relevant to the present application are omitted.

[0028] The application scenarios of RIS mainly include two categories: traditional communication scenarios and new applications. The application of traditional communication scenarios includes overcoming coverage holes, edge coverage enhancement, indoor coverage enhancement, hotspot flow enhancement, line-of-sight multi-flow transmission, large-scale antenna transceiver, etc. New applications include high-precision positioning, vehicle networking communication, unmanned aerial vehicle communication, secure communication, reduction of electromagnetic pollution, reduction of mobile edge network delay, etc. RIS can transmit and reflect signals to a certain direction, and can also reduce electromagnetic pollution by adjusting the amplitude and absorbing electromagnetic waves, and reflect some electromagnetic pollution waves to a direction that will not cause electromagnetic pollution, to achieve the purpose of inhibiting electromagnetic pollution. The 3GPP R18 network controlled repeater (network controlled repeater) project specifies the following side control information: beam information, UL / DL TDD configuration, ON-OFF information.

[0029] According to the main body of the control RIS, the RIS can be divided into two categories: C-RIS controlled by communication service equipment and S-RIS controlled by sensing service equipment.

[0030] FIG. 1A, 1B, 1C, 1D are schematic diagrams showing system scenarios of a communication and perception integrated system, respectively. For example, in the communication and perception integrated system, there are separate communication signals for communication services as shown in FIG. 1A; there are separate perception signals for perception services as shown in FIG. 1B; there are integrated communication and perception signals for both communication and perception services as shown in FIG. 1C; and there are blockchain P2P networks between base stations as shown in FIG. 1D. RIS / NCRs are deployed in the network to improve the performance of communication and perception services. RIS / NCRs are amplify-and-forward relay nodes with beamforming capability, so they will amplify noise / interference. The gNB allows the NCR to effectively perform its amplify-and-forward operation through side control information. The NCR can be regarded as a network-controlled “beam bender” relative to the gNB. The forwarding operation is performed entirely in the analog domain, resulting in a delay on the order of tens of nanoseconds, which can be fully managed using existing time alignment procedures. Inter-base-station blockchain networks can be formed to record and synchronize usage information for RISs. The core network perception function management entity unit manages the quality of service (QoS) and / or quality of experience (QoE) for different perception services to receive perception service requests, perform service perception and resource scheduling according to different perception service types such as detection, positioning, tracking, identification, and imaging.

[0031] The present disclosure provides an electronic device in a communication and perception integrated system according to one 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 to perform: obtaining parameter information about parameters of a reconfigurable intelligent surface for a first predetermined task, for determining, based on the parameter information, whether interference of the reconfigurable intelligent surface on a second predetermined task to be performed by the electronic device meets a predetermined condition, thereby for reconfiguring the parameters of the reconfigurable intelligent surface, wherein the first predetermined task is one of a communication task and a perception task, and the second predetermined task is the other of the communication task and the perception task.

[0032] FIG. 2 shows an exemplary functional module block diagram of an electronic device 200 in a communication and perception integrated system according to one embodiment of the present disclosure.

[0033] As shown in FIG. 2, the electronic device 200 includes a control unit 201 which performs control, and a processing unit 203 which can be configured to, under control of the control unit 201, acquire parameter information about parameters of the reconfigurable intelligent surface for a first predetermined task, to judge, based on the parameter information, whether interference of the reconfigurable intelligent surface on a second predetermined task to be performed by the electronic device 200 meets a predetermined condition, thereby to reconfigure the parameters of the reconfigurable intelligent surface, wherein the first predetermined task is one of a communication task and a sensing task, and the second predetermined task is the other of the communication task and the sensing task.

[0034] The control unit 201 and the processing unit 203 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 to perform processing, etc. It should be understood that the various functional units in the electronic device 200 shown in FIG. 2 are only logical modules divided according to the specific functions they implement, and are not intended to limit the specific implementation manner.

[0035] The electronic device 200 can be disposed at a base station side or communicatively connected to a base station, for example. For example, the electronic device 200 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 200 to implement various functions. The transceiver can include one or more communication interfaces to support communication with different devices (e.g., UEs, base stations, etc.), and the implementation form of the transceiver is not specifically limited here.

[0036] As an example, the base station can be an eNB or a gNB, for example.

[0037] For example, the electronic device 200 can work as the 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 by the electronic device 200 to implement various functions. The transceiver can include one or more communication interfaces to support communication with different devices (e.g., UEs, base stations, etc.), and the implementation form of the transceiver is not specifically limited here.

[0038] As an example, the predetermined condition can be that the interference of the reconfigurable intelligent surface on the second predetermined task to be performed by the electronic device 200 exceeds a predetermined threshold. As an example, the predetermined threshold can be determined by a person skilled in the art according to experience or application scenarios.

[0039] For example, in a case where the first predetermined task is a communication task and the second predetermined task is a perception task, it is determined that the above predetermined condition is satisfied if interference of the reconfigurable intelligent surface on the perception task results in that a perception result cannot satisfy a predetermined perception accuracy or a predetermined perception precision, or if interference of the reconfigurable intelligent surface on the perception task results in that a false detection probability is greater than a predetermined threshold. Other examples of the predetermined condition can also be conceived by those skilled in the art, which are not listed here.

[0040] As an example, the electronic device 200 can be a communication receiver (i.e., a communication signal receiver) or a perception signal receiver (i.e., a perception signal receiver). The above receiver can be a base station or a UE.

[0041] Hereinafter, the communication task is sometimes referred to as a communication service or a communication service, and the perception task is sometimes referred to as a perception service or a perception service.

[0042] For example, the parameters (configuration parameters) of the RIS include at least one of beam information, uplink and downlink configuration information, on-off time domain resource information, perception or communication configuration information, but are not limited thereto. According to embodiments of the present disclosure, the RIS can be configured for a perception service or a communication service, and the corresponding task target is achieved.

[0043] For example, a base station providing a communication service determines that the coverage of the communication signal needs to be enhanced according to the measurement report of the UE, and then controls the related parameters of the RIS, such as beam information, uplink and downlink configuration, time domain resource configuration, on and off, etc. The base station enabling the RIS sends the RIS configuration parameter information to other receiving base stations providing a perception service.

[0044] In the existing integrated communication and perception system, due to the coexistence of communication signals and perception signals, only using RIS to enhance the coverage of communication signals may potentially interfere with perception services. However, in the electronic device 200 according to embodiments of the present disclosure, through the joint control of the RIS by the communication task and the perception task, the QoS of the communication and perception services can be guaranteed at the same time, the service quality is improved, and the mutual interference between the communication task and the perception task is reduced, thereby improving the efficiency of spectrum sharing between the communication task and the perception task in the integrated communication and perception system (which can also be referred to as a communication and perception fusion network), and improving the spectrum utilization.

[0045] As an example, the first signal for the first predetermined task and the second signal for the second predetermined task are the same signal, and the reconfigurable intelligent surface is also used for the second predetermined task. That is, the perception service and the communication service are simultaneously performed using a communication and perception integrated signal, which means that the same wireless signal is used to simultaneously perform the communication and perception services.

[0046] For example, the joint communication and sensing signals are transmitted by a unified transmitter, and the communication receiver and the sensing signal receiver can be separately set according to the business scenario. Wireless communication signal-based sensing can be performed, such as WiFi signal and cellular signal-based target detection, weather state detection, and the like. Due to the non-stationary characteristics of the communication signal, the sensing performance will be limited.

[0047] As an example, the processing unit 203 can be configured to compensate the second signal if the interference meets a predetermined condition.

[0048] As an example, in the case where the first predetermined task is a sensing task and the second predetermined task is a communication task, the communication signal is compensated by enhancing the communication signal by directing (e.g., aiming) the reflective beam of the reconfigurable intelligent surface towards the communication signal receiver.

[0049] As an example, the first predetermined task is a communication task, the second predetermined task is a sensing task, and in the case where the reconfigurable intelligent surface is used for downlink transmission in the first predetermined task, the gain to be compensated for the second signal is determined according to the direction and gain of the reflective beam of the reconfigurable intelligent surface. For example, the second signal is compensated by modifying the sensing algorithm according to the direction and gain of the reflective beam of the reconfigurable intelligent surface, by modifying certain parameters of the sensing algorithm.

[0050] In the case where the RIS is configured for DL (downlink), the gain to be compensated for the sensing signal separated by the sensing signal receiver is determined according to the direction and gain of the reflective beam of the RIS. The RIS can be regarded as a new sensing signal transmission source, and a multi-transmission signal sensing algorithm is used to determine the sensing result.

[0051] As an example, the first predetermined task is a communication task, the second predetermined task is a sensing task, and in the case where the reconfigurable intelligent surface is used for uplink transmission in the first predetermined task, the reflective beam of the reconfigurable intelligent surface is regarded as background noise of the second predetermined task. For example, in the case where the RIS is configured for UL (uplink), the reflective beam of the RIS is equivalent to background noise for the sensing task, which needs to be considered when performing a sensing algorithm (e.g., a detection algorithm).

[0052] Multi-sensing requires detailed link budget evaluation. Take target detection as an example, the sensing signal receiver determines the position of the target and extracts the features by analyzing the signal strength (RSSI), time of flight (TOF), phase change, angle of arrival, etc. of the sensing received signal. FIG. 3 is a schematic diagram showing a scenario in which the integrated sensing and communication transmitter transmits a joint communication and sensing signal. As shown in FIG. 3, when no RIS is used in the network, the reflected signal of the sensing target received by the sensing signal receiver only includes signal ①, and the threshold for target detection is assumed to be T1 at this time; if the RIS is used to enhance the communication coverage, it is equivalent to adding a sensing transmission signal at the position of the RIS, and the signal reflected by the sensing target received by the sensing signal receiver includes signals ① and ②. In order to improve the accuracy of detection, the detection threshold needs to be set to T2 under the condition of considering other multipath signals and background noise, and T2 should be greater than T1 at this time. The extraction of other signal measurement indicators such as TOA and DOA signals can refer to the literature “A. Liu et al., A Survey on Fundamental Limits of Integrated Sensing and Communication, https: / / arxiv.org / pdf / 2104.09954”. Common signal estimation algorithms such as periodogram (Periodogram) algorithm, rotation invariant estimation (ESPRIT) algorithm, and pulse Doppler radar algorithm.

[0053] As an example, the processing unit 203 can be configured to send the result obtained by performing the second predetermined task to the sensing service management apparatus, so that the sensing service management apparatus evaluates the QoS based on the result and determines whether the parameters need to be reconfigured.

[0054] For example, the sensing service management apparatus can be a sensing service management function in the core network. The sensing service management function evaluates the QoS and performance of the sensing service, determines whether the presence of the RIS has a negative impact on the sensing performance, and whether the parameters of the RIS need to be reconfigured. Or, it is determined whether to enable other RIS panels for compensation. Thus, the RIS can be reconfigured according to the QoS of the sensing service, or multiple RIS configurations can be performed.

[0055] As described above, the base station participating in sensing adjusts the sensing receiving algorithm according to the RIS related information to obtain the sensing result. And reports to the core network sensing service management function to evaluate the sensing performance, and determine whether to adjust the configuration of the RIS. Thus, compensation can be made through the sensing algorithm according to the configuration parameters of the RIS, and more accurate sensing can be achieved.

[0056] As an example, the electronic device 200 can be a node in a distributed architecture network, and the processing unit 203 can be configured to perform consensus verification on the parameter information. As an example, the distributed architecture network includes a blockchain. The consensus verification here is to ensure the consistency and validity of the blockchain ledger. Commonly used consensus algorithms can be used, such as proof of work, proof of stake, practical Byzantine fault tolerance (PBFT), etc. Based on the blockchain, the problem of unintended abnormal regulation of RIS to “non-target signals” from other networks can be solved, and the consensus authentication of the distributed intelligent reflecting surface is realized through the blockchain, solving the coexistence problem of communication and sensing services. Other examples of distributed architecture can also be conceived by those skilled in the art, which are not repeated here. In the following, for ease of description, it is assumed that the device participating in the sensing service is a base station.

[0057] FIG. 4 shows an example of a processing flow when the communication signal and the sensing signal are the same signal according to an embodiment of the present disclosure. In FIG. 4, as an example, the first predetermined task is a communication task, the second predetermined task is a sensing task, and the electronic device 200 is, for example, a sensing signal receiving base station (labeled as sensing receiving gNB in FIG. 4), and the sensing service management apparatus can be a sensing service management function in the core network.

[0058] In step 1, the sensing service management function receives a sensing task request from a sensing application or other functions in the core network, and determines a list of base stations participating in the sensing service according to the task type and requirements, including sensing signal transmitting base stations and sensing signal receiving base stations. This flow example considers a co-sensing integrated signal when communication and sensing are performed simultaneously, i.e., an ISAC gNB (co-sensing integrated transmitter) is used to transmit communication signals and sensing signals simultaneously, and the communication signal receiver and the sensing signal receiving base station can be set up for signal separation according to the business scenario.

[0059] In step 2, the sensing service management function informs the relevant base stations participating in the sensing and their tasks.

[0060] In step 3, the ISAC gNB receives measurement reports from the UE, including various periodic and aperiodic reports.

[0061] In step 4, the ISAC gNB determines whether signal enhancement using RIS is needed according to the UE measurement report, and determines the required RIS parameters, including beam information, UL / DL configuration information, ON / OFF time, etc.

[0062] In step 5, the ISAC gNB uploads the determined enabled RIS parameter information to the blockchain, completes the consensus, and synchronizes to other nodes on the blockchain.

[0063] In step 6, the ISAC gNB sends RIS control information to the corresponding RIS.

[0064] In step 7, the perception signal receiving base station participating in the perception service acquires the RIS information from the blockchain, locally judges the influence of the RIS panel on the perception signal during the perception, and inputs the influence of the RIS information into the perception algorithm for compensation when calculating the perception result. The compensation performed is, for example, as described above: when the RIS is configured for DL (downlink), according to the RIS reflection beam direction and gain, the gain to be compensated for the perception signal separated by the perception signal receiving base station is determined; when the RIS is configured for UL (uplink), the reflection beam of the RIS is equivalent to background noise for the perception task, which needs to be considered when the detection algorithm is executed.

[0065] In step 8, the multiple perception signal receivers participating in the perception service simultaneously send the perception results to the core network perception service management function.

[0066] In step 9, the perception service management function evaluates the QoS and / or QoE of the perception service, determines whether the existence of the RIS has a negative impact on the perception performance, and whether the parameters of the RIS need to be reconfigured or other RIS panels need to be enabled for compensation.

[0067] In step 10, the perception service management function feeds back the RIS information that needs to be reconfigured to the corresponding control base station.

[0068] As an example, the processing unit 203 can be configured to verify the parameter information before performing the second predetermined task, and determine that the verification fails in the case where the interference meets the predetermined condition, wherein the parameters are reconfigured until the verification succeeds.

[0069] For example, before the basic consensus algorithm of FIG. 4, a judgment on the influence of the RIS on the perception service is added, and the function of evaluating the result after the completion of the perception task in FIG. 4 is performed in advance at the local of the perception signal receiving base station.

[0070] FIG. 5 shows another example of a processing flow in the case where the communication signal and the perception signal are the same signal according to an embodiment of the present disclosure. The difference between FIG. 5 and FIG. 4 is mainly in steps 6, 7, and 9 of FIG. 5.

[0071] The processing flow of FIG. 5 is briefly introduced as follows.

[0072] In step 1, the perception service management function receives a perception task request from a perception application or other functions of the core network, and determines a list of base stations participating in the perception service, including perception signal transmitting base stations and perception signal receiving base stations, according to the task type and requirements. This process example considers the integrated sensing and communication signal that is transmitted simultaneously by the ISAC gNB (integrated sensing and communication transmitter) while communication and sensing are carried out simultaneously. The communication signal receiver and the perception signal receiving base station can be set up for signal separation according to the business scenario.

[0073] In step 2, the perception service management function notifies the related base stations participating in the perception and their tasks.

[0074] In step 3, the ISAC gNB receives measurement reports from the UE, including various periodic and aperiodic reports.

[0075] In step 4, the ISAC gNB determines whether signal enhancement is needed by using RIS according to the UE measurement report, and determines the required RIS parameters, including beam information, UL / DL configuration information, ON / OFF time, etc.

[0076] In step 5, the ISAC gNB uploads the determined RIS parameter information for activation to the blockchain.

[0077] In step 6, when each perception receiving base station obtains the RIS parameter information from the blockchain, it determines whether the interference with its own perception result meets the predetermined condition (i.e., consensus verification of the RIS parameter information). If the interference does not meet the predetermined condition, the authentication is passed, the consensus is completed, and then the RIS parameter information is synchronized to other nodes on the blockchain; otherwise, the verification fails (consensus verification fails).

[0078] In step 7, the ISAC gNB determines whether to reconfigure the RIS parameters. For example, if the consensus verification fails, the ISAC gNB determines to reconfigure the RIS parameters until it does not affect other base stations to perform the perception service, and then successfully completes the consensus.

[0079] In step 8, the ISAC gNB sends RIS control information to the corresponding RIS.

[0080] In step 9, after the consensus is passed, the perception base stations participating in the perception task start to perform the wireless perception service.

[0081] In step 10, the perception signal receiving base station sends the corresponding perception result to the perception service management function.

[0082] In step 11, the perception service management function feeds back to the application initiating the perception service request after fusing or further processing the perception result.

[0083] As an example, the first signal for the first predetermined task and the second signal for the second predetermined task are independent of each other. For example, the communication signal and the sensing signal are multiplexed in the same frequency band in an orthogonal or non-orthogonal manner, while the communication and sensing functions are performed simultaneously.

[0084] In this scenario, the implementation of the sensing service can be more flexible, and the sensing service can be based on wireless communication signals, or based on traditional radar signals or other customized sensing signals for certain sensing tasks.

[0085] The wireless signals incident on the RIS panel include not only the "target signal" optimized and regulated by the RIS, such as the communication signal that needs to be enhanced in coverage, but also other "non-target signals", such as the sensing signal for sensing services. The RIS will regulate both types of signals. By regulating the amplitude, phase, polarization mode, etc. of electromagnetic waves, the RIS can enhance the "target signal", while also performing unintended abnormal regulation on the "non-target signal". In the uncontrolled case, the RIS performs unintended abnormal regulation on the "non-target signal" from other networks, which will cause serious network coexistence problems.

[0086] In this scenario, C-RIS controlled by a communication service base station and S-RIS controlled by a sensing service base station are considered respectively. Among them, C-RIS represents an RIS controlled by a communication service base station, the main purpose of which is to enhance the signal quality of users in blind areas, ensure the coverage of users in dead zones, and improve the transmission rate. S-RIS represents an RIS controlled by a sensing service base station, the main purpose of which is to improve the performance of sensing services, such as detection probability, positioning accuracy, etc. RIS can be flexibly configured according to different service requirements.

[0087] As an example, the reconfigurable intelligent surface is a first reconfigurable intelligent surface, and the processing unit 203 can be configured to determine whether compensation of the second signal needs to be performed using a second reconfigurable intelligent surface for a second predetermined task in the case that the interference meets a predetermined condition. For example, in the case that the first predetermined task is a communication task and the second predetermined task is a sensing task, the S-RIS can be used to compensate for the unintended regulation of the sensing signal by the C-RIS.

[0088] As an example, the first reconfigurable intelligent surface is one of the C-RIS and the S-RIS, and the second reconfigurable intelligent surface is the other of the C-RIS and the S-RIS.

[0089] As an example, compensation is performed by reducing the interference of the first reconfigurable intelligent surface on the second predetermined task through the second reconfigurable intelligent surface.

[0090] As an example, the second signal is enhanced by the second reconfigurable intelligent surface, thereby compensating.

[0091] FIG. 6 shows an example of a processing flow when the communication signal and the perception signal are independent of each other according to an embodiment of the present disclosure. In FIG. 6, as an example, the first predetermined task is a communication task, and the second predetermined task is a perception task. The electronic device 200 is, for example, a perception signal receiving base station, and the perception service management apparatus can be a perception service management function. In FIG. 6, C-gNB denotes a communication signal transmitting base station, and S-gNB denotes a perception signal receiving base station.

[0092] In step 1, the perception service management function receives a perception task request from a perception application or other functions of a core network, and determines a list of base stations participating in the perception service according to the task type and requirements, including perception signal transmitting base stations and perception signal receiving base stations.

[0093] In step 2, the perception service management function informs the relevant base stations participating in the perception and their tasks.

[0094] In step 3, the C-gNB receives measurement reports from the UE, including various periodic and aperiodic reports.

[0095] In step 4, the C-gNB determines whether signal enhancement using C-RIS is needed according to the UE measurement report, and determines the required RIS parameters, including beam information, UL / DL configuration information, ON / OFF time, etc.

[0096] In step 5, the C-gNB uploads the determined C-RIS parameter information for activation to the blockchain, and synchronizes it to other nodes on the blockchain.

[0097] In step 6, the blockchain performs a consensus authentication process, and the perception base station determines that the activation of the above C-RIS will not cause harmful effects on the perception service, and then passes the authentication.

[0098] In step 7, the C-gNB sends C-RIS control information to the corresponding C-RIS.

[0099] In step 8, the perception base station determines the impact on the perception service according to the parameter information of the C-RIS, determines whether the S-RIS needs to be used to compensate for the impact of the C-RIS and improve the performance of the perception service, and determines the required parameters of the S-RIS. For example, as described above, the interference of the C-RIS on the perception task can be reduced by the S-RIS, thereby compensating; the perception signal can be enhanced by the S-RIS, thereby compensating.

[0100] In step 9, the perception base station sends the control parameters of the S-RIS to the S-RIS.

[0101] As an example, the electronic device 200 is a node in a distributed architecture network, and in a case where it is determined via the distributed architecture network that the reconfigurable intelligent surface can be used for both the first predetermined task and the second predetermined task, parameters of the reconfigurable intelligent surface for the first predetermined task and the second predetermined task are allocated. In this way, the parameters of the reconfigurable intelligent surface for the first predetermined task and the second predetermined task can be dynamically adjusted. For example, the right to use the RIS can be traded between the communication service and the perception service through the blockchain. For each base station-controlled RIS, the communication service and the perception service can trade the configuration parameters of the RIS, such as the time domain resource configuration for the perception and communication services, the beam direction, the on and off, and the like, through the blockchain. That is, for an RIS shared by the communication and perception services, the RIS configuration parameters of the perception service and the communication service can be allocated through the blockchain to realize the trade of the right to use the RIS.

[0102] FIG. 7 shows an example of a process flow of trading the right to use the RIS between the communication service and the perception service through the blockchain in a case where the communication signal and the perception signal are independent of each other according to an embodiment of the present disclosure. In FIG. 7, as an example, the electronic device 200 is, for example, a perception base station (S-gNB) or a communication base station (C-gNB).

[0103] In step 1, the C-gNB receives a measurement report from the UE, including various periodic and aperiodic reports.

[0104] In step 2, the C-gNB determines the demand of the communication service for the use of the RIS according to the measurement report of the UE, and uploads the blockchain.

[0105] In step 3, the S-gNB determines the demand of the perception service for the use of the RIS according to the demand of the perception task, and uploads the blockchain.

[0106] In step 4, through the smart contract, it is determined whether the communication and perception services can use the RIS at the same time and the optimal RIS parameters that meet the communication demand and the perception demand are determined. If not, the RIS is allocated for the time domain resource configuration of the communication service and the perception service according to the demand of the communication and perception services, and the right to use the RIS is traded.

[0107] In step 5, the blockchain smart contract sends the RIS configuration result to the corresponding RIS control base station (C-gNB or S-gNB).

[0108] In step 6, the RIS control base station sends the respective RIS configuration parameters to the corresponding RIS.

[0109] In step 7, the RIS configures the RIS as the corresponding parameters of the communication service and the sensing service on the specified time domain resource according to the configuration parameters, including beam information, on / off time, etc.

[0110] According to the embodiments of the present disclosure, the RIS configuration parameters of the sensing service and the communication service can be allocated through the blockchain, and the transaction of the RIS usage right can be realized.

The electronic device 8000 includes 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 8000 to perform: obtaining a result obtained by performing a second predetermined task in a case where a reconfigurable intelligent surface for a first predetermined task exists, and determining whether interference of the reconfigurable intelligent surface on the second predetermined task meets a predetermined condition based on the result, thereby being used for reconfiguring a parameter of the reconfigurable intelligent surface, wherein the first predetermined task is a communication task, and the second predetermined task is a sensing task.

[0112] FIG. 8 shows an exemplary functional module block diagram of an electronic device 8000 in a communication-sensing integrated system according to another embodiment of the present disclosure.

[0113] As shown in FIG. 8, the electronic device 8000 includes a control unit 8001 that controls, a communication unit 8003 that obtains, under the control of the control unit 8001, a result obtained by performing a second predetermined task in a case where a reconfigurable intelligent surface for a first predetermined task exists, and a processing unit 8005 that determines, under the control of the control unit 8001, whether interference of the reconfigurable intelligent surface on the second predetermined task meets a predetermined condition based on the result, thereby being used for reconfiguring a parameter of the reconfigurable intelligent surface.

[0116] In the electronic device 8000 according to the embodiment of the present disclosure, through the joint control of the RIS by the communication task and the perception task, the QoS of the communication and the perception service can be guaranteed at the same time, the service quality is improved, and the mutual interference of the communication task and the perception task is reduced, thereby improving the efficiency of the spectrum sharing of the communication task and the perception task in the communication-perception integrated system and improving the spectrum utilization.

[0117] As an example, the processing unit 8005 can be configured to evaluate the QoS based on the result and determine whether the parameters need to be reconfigured. The electronic device 8000 can evaluate the QoS and performance of the perception service, determine whether the presence of the RIS has a negative impact on the perception performance, and whether the parameters of the RIS need to be reconfigured. Or, determine whether to enable other RIS panels for compensation. Thus, the RIS can be reconfigured according to the QoS of the perception service, or multiple RIS configurations can be performed.

Furthermore, 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.

[0127] [Application examples regarding base stations]

[0128] (First application example)

[0129] Fig. 11 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 the eNB as an example, but is equally applicable to the gNB. The eNB 800 includes one or plural 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.

[0130] Each of the antennas 810 includes a single or plural antenna elements, such as plural antenna elements included in a multiple-input multiple-output (MIMO) antenna, and is used for the base station device 820 to transmit and receive radio signals. As illustrated in Fig. 11, the eNB 800 can include plural antennas 810. For example, the plural antennas 810 can be compatible with plural frequency bands used by the eNB 800. While Fig. 11 illustrates an example in which the eNB 800 includes plural antennas 810, the eNB 800 can also include a single antenna 810.

[0131] The base station device 820 includes a controller 821, a memory 822, a network interface 823, and a radio communication interface 825.

[0132] 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 radio communication interface 825, and transfers the generated packets via the network interface 823. The controller 821 can bundle data from plural 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.

[0133] The network interface 823 is a communication interface for connecting the base station apparatus 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.

[0134] 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 storing a communication control program, or a module including a processor and related circuitry configured to execute the program. Updating the program can cause the function of the BB processor 826 to change. The module can be a card or a blade inserted into a slot of the base station apparatus 820. Alternatively, the module can also be a chip 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.

[0135] As illustrated in FIG. 11, 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. 11, 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. Although FIG. 11 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 include a single BB processor 826 or a single RF circuit 827.

[0136] The electronic device 200 as illustrated in FIG. 2, when implemented as the eNB 800 illustrated in FIG. 11, 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. For example, the controller 821 can control the reconfigurable intelligent surface jointly by the communication task and the sensing task by performing the functions of the units in the electronic device 200, while guaranteeing the quality of service of the communication and sensing traffic.

As illustrated in FIG. 12, the eNB 830 can include a plurality of antennas 840. For example, the plurality of antennas 840 can be compatible with a plurality of frequency bands used by the eNB 830.

The controller 851, the memory 852, and the network interface 853 are the same as the controller 821, the memory 822, and the network interface 823 described with reference to FIG. 12.

[0141] 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 antenna 840. The wireless communication interface 855 can generally include, for example, a BB processor 856. The BB processor 856 is the same as the BB processor 826 described with reference to FIG. 12, except that the BB processor 856 is connected to the RF circuit 864 of the RRH 860 via the connection interface 857. As shown in FIG. 12, the wireless communication interface 855 can include a plurality of BB processors 856. For example, the plurality of BB processors 856 can be compatible with a plurality of frequency bands used by the eNB 830. Although FIG. 12 shows an example in which the wireless communication interface 855 includes a plurality of BB processors 856, the wireless communication interface 855 can also include a single BB processor 856.

[0142] 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 high-speed line described above.

Although FIG. 12 shows 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.

[0146] The electronic device 200 shown in FIG. 2, when implemented as the eNB 830 shown in FIG. 12, its transceiver can be implemented by the wireless communication interface 855. At least a part of the functions can also be implemented by the controller 851. For example, the controller 851 can control the reconfigurable intelligent surface jointly through the communication task and the sensing task by performing the functions of the units in the electronic device 200, while guaranteeing the quality of service of the communication and sensing services.
