Description

Technical Field

[0001] This disclosure relates to the field of integrated communication sensing technology, and more specifically to electronic devices in integrated communication sensing systems, methods for integrated communication sensing systems, and computer-readable storage media. More specifically, it relates to electronic devices and methods for achieving sensing tasks through uplink cooperation between user equipment and multiple base stations based on uplink reference signals. Background Technology

[0002] Integrated Sensing and Communication (ISAC) is a key technology in 5G-A and 6G communication networks, also known as joint radar communication systems. It utilizes the propagation characteristics of radio waves to depict and reconstruct the physical world, enabling a sensing network. Through the synergy of network sensing and terminal sensing, it can model the entire physical world covered by the network and provide sensing-assisted communication and communication-assisted sensing. ISAC is an emerging technology that integrates wireless communication and sensing capabilities. It achieves resource sharing, such as spectrum, hardware, and signal processing platforms, by merging radar sensing and wireless communication.

[0003] Figure 1 This is a diagram illustrating the sensing patterns associated with base stations and user equipment. Figure 1 In the middle, the first row from left to right shows the single-site sensing mode of the base station (gNB) for the target object, the dual-site sensing mode of gNB to UE (user equipment), and the dual-site sensing mode of gNB to gNB. The second row from left to right shows the single-site sensing mode of UE, the dual-site sensing mode of UE to gNB, and the dual-site sensing mode of UE to UE.

[0004] Since the bandwidth resources and coverage of a single base station are limited, it is easier to meet the communication and perception needs of users by concentrating the wireless resources of multiple cells or multiple base stations to provide communication and perception services.

[0030] 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.

[0031] 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.

[0032] Figure 2a This is a schematic diagram illustrating the sensing mode of a single transceiver device; Figure 2b This is a schematic diagram illustrating a multi-device collaborative receiving and sensing mode.

[0033] In such Figure 2aWhen using a pair of transceivers (single UE - single gNB), the frequency change of a specific action of the sensed object may be zero. Therefore, the action segment may not be detectable. Thus, multiple devices are needed to construct the frequency profile and extract a series of directional changes, which is impossible with a single pair of transceivers. This application considers using... Figure 2b The multi-device collaborative reception sensing mode (single UE - multiple gNBs) shown is used to achieve sensing.

[0034] Figure 3 A network architecture suitable for sensing services with New Radio (NR) access, according to an embodiment of this disclosure, is shown.

[0035] like Figure 3 As shown, the AMF (Access and Mobility Management Function) of the core network receives a sensing service request (also known as a sensing task) related to a specific target UE from other entities (such as UEs), or the AMF itself decides to initiate a sensing service on behalf of a specific target UE. The AMF then sends the sensing service request to the SF (Sensing Function) of the core network. The SF processes the sensing service request, which may include transmitting auxiliary data to the target UE to assist in UE-based and / or UE-assisted sensing and / or target UE sensing. The SF then returns the results of the sensing service to the AMF (e.g., UE location estimation). In cases where a sensing service is requested by an entity other than the AMF (such as the UE), the AMF returns the sensing service results to that entity. Figure 3 In this context, NR-Uu represents the interface between the UE and the gNB, Xn represents the interface between gNBs, NS1 represents the interface between the AMF and the SF, NG-C represents the interface between the AMF and the gNB, and NG-RAN is an abbreviation for Next Generation Radio Access Network.

[0036] This disclosure provides an electronic device 400 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 to, through the at least one processor, cause the electronic device 400 to perform: a sensing task related to a user device within the service range of the electronic device 400, based on an uplink reference signal, and together with a cooperating electronic device and a user device for cooperating in completing the sensing task.

[0037] Figure 4 An exemplary functional block diagram of an electronic device 400 in a communication-sensing integrated system according to an embodiment of the present disclosure is shown.

[0038] like Figure 4As shown, the electronic device 400 includes: a control unit 401 for control; and a processing unit 403 configured to, under the control of the control unit 401, perform sensing tasks related to user equipment within the service range (i.e., coverage area) of the electronic device 400, based on uplink reference signals, together with cooperating electronic devices and user equipment for collaboratively completing the sensing tasks.

[0039] 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., and 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... Figure 4 The functional units in the electronic device 400 shown are logical modules divided according to the specific functions they implement, rather than being used to limit the specific implementation method.

[0040] 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.

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

[0042] For example, perception tasks related to user equipment may include UE-based and / or UE-assisted perception and / or target UE perception.

[0043] According to embodiments of this disclosure, sensing tasks can be achieved through uplink collaboration between the UE and multiple base stations (electronic devices 400 and cooperating electronic devices) based on uplink reference signals.

[0044] As an example, uplink reference signals include uplink channel sounding reference (SRS) or demodulation reference (DMRS).

[0045] In the following text, for the sake of simplicity, the electronic device 400 will sometimes be referred to as the main base station, the uplink reference signal will sometimes be referred to as the uplink sensing reference signal or sensing reference signal, and the cooperating electronic device will sometimes be referred to as the cooperating base station.

[0046] As an example, the cooperating electronic device (EED) is selected by the core network based on the measurement results of the uplink reference signal. For instance, the selection of the EED can be based on a comparison of the Received Reference Power (RSRP) values ​​measured by other base stations around the primary base station for the UE's uplink reference signal, or on the location information of other base stations, and according to different sensing service requirements, the EED for cooperative sensing can be selected. The EED can cover the UE.

[0047] As an example, processing unit 403 can be configured to determine the time-frequency resources and configuration information of the uplink reference signal based on a request received from the core network. To obtain uplink measurements, the base station needs to know the characteristics of the sensed reference signal transmitted by the UE during the time period required to perform the uplink measurement. These characteristics should be static during the periodic sensed reference signal transmissions during uplink measurement. Therefore, the SF will instruct the main base station to guide the UE to transmit sensed reference signals for uplink sensing.

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

[0049] The IE SRS-Config (an IE for all SRS configurations) is used to configure reference signal transmission. This configuration defines the lists of SRS-Resources, SRS-PosResources, SRS-PosResourceSets, and SRS-ResourceSets. Each resource set defines either a set of SRS-Resources or SRS-PosResources. The network uses the configured aperiodic SRS-ResourceTrigger (L1 DCI) to trigger transmissions of either the SRS-Resources or SRS-PosResources sets.

[0050] Refer to TS38.331 6.3.2 Radio resource control information elements SRS-Config for SRS resource set configuration.

[0051]

[0052] Refer to TS38.331 6.3.2 Radio resource control information elements SRS-Config for SRS resource configuration.

[0053]

[0054]

[0055]

[0056] NR DMRS can be transmitted in various schemes, including time-domain DMRS and frequency-domain DMRS. The choice of scheme depends on the specific NR configuration and requirements. Time-domain DMRS refers to DMRS symbols being distributed across different time slots within a subframe. Frequency-domain DMRS refers to DMRS symbols being distributed across different frequency resources within a subcarrier interval.

[0057] Referring to the 3GPP NRPositioning 5G positioning standard, IE DMRS-UplinkConfig is used to configure the uplink demodulation reference signal of PUSCH.

[0058]

[0059]

[0060]

[0061] For simplicity, the following explanation uses the SRS (Search Engine Reference Signal) as an example. Those skilled in the art will understand that the explanation using SRS as an example also applies to DMRS.

[0062] Referring to Table 8.13.2.1-1 in the 3GPP NRPositioning 5G positioning standard, the UE configuration data that may be transferred from serving gNB to the SF (TS38.305 8.13) is listed.

[0063]

[0064] Referring to Table 8.13.2.3-1 in the 3GPP NR Positioning 5G positioning standard, the UL-SRS transmission characteristics information that can be sent from the SF to the gNB is listed.

[0065]

[0066]

[0067] As described above, the SF sends a message to the main base station requesting configuration information for the uplink reference signal. If the message includes requested UL-SRS transmission characteristic information similar to that listed in Table 8.13.2.3-1, the main base station should consider this information when configuring UL-SRS transmission for the UE.

[0068] As an example, processing unit 403 can be configured to send the time-frequency resources and configuration information of the uplink reference signal to the core network, so that the core network can send the time-frequency resources and configuration information to the cooperating electronic devices for the cooperating electronic devices to perform sensing tasks (so that the cooperating electronic devices can receive and decode the uplink reference signal to perform sensing tasks).

[0069] As an example, the processing unit 403 can be configured to configure the uplink reference signal for the user equipment via RRC reconfiguration based on the time-frequency resources and configuration information of the uplink reference signal.

[0070] As an example, the processing unit 403 can be configured to activate or disable a semi-persistent uplink reference signal via a Media Access Control Element (MAC CE).

[0071] As an example, processing unit 403 can be configured to activate or disable aperiodic uplink reference signals via downlink control information (DCI).

[0072] For example, for semi-persistent and aperiodic SRS, the SF requests the primary base station to activate or deactivate the sensing reference signal (that is, the SF sends a sensing activation / deactivation request message to the primary base station to request activation / deactivation of UL-SRS for the UE), while for periodic sensing reference signals, it is skipped.

[0073] For semi-persistent UL sensing reference signals, the master base station can activate the configured semi-persistent UL sensing reference signal resource set by sending a sensing reference signal activation / deactivation MACCE command. For aperiodic UL sensing reference signals, the master base station can activate the configured aperiodic UL sensing reference signal resource set by sending a TSDCI.

[0074] Referring to Table 8.13.2.3-3 in the 3GPP NRPositioning 5G positioning standard, the activation / deactivation information that can be sent from the SF to the main base station is listed.

[0075]

[0076] As an example, the processing unit 403 can be configured to report sensing data obtained based on uplink reference signals to the core network, so that the core network can fuse the sensing data and sensing data from cooperating electronic devices to obtain the sensing results of the sensing task.

[0077] As an example, the sensing data includes at least one of the detection probability, phase, and power of the uplink reference signal.

[0078] Referring to Table 8.13.2.2-1 in the 3GPP NRPositioning 5G positioning standard, the measurement results that may be transferred from gNBs to the SF (TS38.305 8.13) are listed.

[0079]

[0080] Figure 5 An example of a sensing measurement processing flow based on an uplink sensing reference signal according to an embodiment of the present disclosure is shown. For ease of description, the uplink sensing reference signal will be simply referred to as the sensing reference signal in this example flow.

[0081] Step 1: The SF requests the UE to perceive relevant capabilities, and then the UE reports its capability information.

[0082] Not all devices in the network support sensing capabilities; for example, only some UEs support sensing and can interact with the SF (Sensing Network Element). Furthermore, each network element has its own designated service area. Therefore, to successfully execute a sensing service request, devices supporting sensing capabilities need to notify the sensing network element (SF) of their sensing capabilities. Different sensing services involve different requirements, and the SF will query the UE's capabilities specifically based on the sensing service requirements. The UE's capabilities are used by the main base station to configure the sensing reference signal. The UE's capabilities may include, for example, the transmission period of the sensing reference signal (e.g., SRS transmission period).

[0083] Step 2: SF requests the time and frequency resources and configuration information of the sensing reference signal from the main base station.

[0084] As mentioned above, in order to obtain uplink measurements, the gNB needs to know the characteristics of the sensing reference signals transmitted by the UE during the time period required to perform uplink measurements. These characteristics should be static during the periodic sensing reference signal transmissions during uplink measurements. Therefore, the SF will instruct the primary base station to guide the UE to transmit sensing reference signals for uplink sensing.

[0085] Step 3: The main base station determines the available resources and configuration information for sensing reference signals.

[0086] Step 4: The main base station configures the sensing reference signal for the UE through RRC reconfiguration using the determined resource and configuration information of the sensing reference signal;

[0087] Step 5: The main base station informs the SF of the resource and configuration information of the sensing reference signal.

[0088] The master base station ultimately decides which resources to allocate for the sensing reference signal and transmits this sensing reference signal configuration information back to the SF so that the SF can forward the sensing reference signal configuration to other cooperating base stations.

[0089] Step 6: The SF selects the cooperative base stations to participate in cooperative sensing.

[0090] As mentioned above, the selection of cooperating base stations can be based on comparing the RSRP values ​​of the UE uplink signal measured by other base stations around the main base station, or based on the location information of each base station and different sensing service requirements, to select cooperating base stations for collaborative sensing.

[0091] Step 7: Send a cooperative sensing request to the selected cooperating base station. A cooperative sensing measurement request can be initiated even without sharing the configuration information of the sensing reference signal among different base stations.

[0092] Step 8: The cooperating base station makes a judgment based on its own sensing capabilities, available resources, and service status, in order to provide feedback ACK or NACK.

[0093] Cooperative base stations can decide (e.g., in the absence of available resources) not to configure resources and subsequently report a NACK.

[0094] Step 9: The cooperating base station sends an ACK to SF to confirm that it can participate in cooperation or a NACK to refuse to participate in cooperation.

[0095] Step 10: When the cooperating base station reports ACK confirmation to the SF, the SF sends the resource and configuration information of the sensing reference signal configured by the main base station for the UE to the cooperating base station, so that the cooperating base station can receive and demodulate the sensing reference signal.

[0096] Steps 11a and 11b: The primary base station and the cooperating base station receive the sensing reference signal sent by the UE.

[0097] Steps 12a and 12b: The main base station and the cooperating base station perform sensing measurements on the sensing reference signal, respectively.

[0098] Step 13: For semi-persistent and aperiodic SRS, the SF requests the main base station to activate or deactivate the sensing reference signal. If it is a periodic sensing reference signal, this step is skipped.

[0099] Steps 14a and 14b: The primary base station and cooperating base stations report the sensing measurement results for the sensing reference signal.

[0100] Step 15: Based on the perception results from the main base station and the cooperating base station, SF performs perception result fusion and can send the perception results to the perception initiator (e.g., UE).

[0101] Collaborative perception can be divided into three basic modes based on the different types of information shared: early fusion, mid-term fusion, and late-term fusion.

[0102] Figure 6 Examples of early fusion, mid-term fusion, and late fusion according to embodiments of this disclosure are shown.

[0103] like Figure 6 As shown in the leftmost diagram, early fusion shares the raw data from all sensing nodes (including the main base station and cooperating base stations), enabling lossless fusion of raw data. An encoder extracts features from the fused raw data, and a decoder obtains the sensing result. In early fusion, cooperative sensing often offers the best performance. However, transmitting the raw data consumes significant communication resources, especially when a large number of base stations are involved. Furthermore, early fusion struggles to meet the demands of scenarios requiring high real-time sensing capabilities.

[0104] like Figure 6 As shown in the middle diagram, intermediate-layer fusion refers to the process where each sensing node (including the main base station and cooperating base stations) first processes (e.g., encodes) the raw data into intermediate-layer features, then fuses (shares) these intermediate-layer features, and finally, based on the fused features, obtains the final sensing result through a decoder. Intermediate-layer features make it easier to recover the original information, and they are also more flexible and easier to compress to save communication resources.

[0105] like Figure 6As shown in the rightmost figure, in the later fusion stage, for each sensing node (including the main base station and cooperating base stations), the raw data is processed (e.g., encoded) into intermediate layer features. Based on these intermediate layer features, an independent sensing result is obtained through a decoder. Then, the sensing results independently generated by each sensing node are fused (shared) to generate the final sensing result. This collaborative method is very cost-effective in terms of communication, but because it is based on the incomplete observations of each sensing node, it inherently contains noise or errors, and the fusion result often suffers more loss compared to the earlier fusion.

[0106] This disclosure provides an electronic device 700 in a communication sensing integrated system according to another 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 to, through the at least one processor, cause the electronic device 700 to perform: performing a sensing task related to the electronic device 700, based on an uplink reference signal, with a network-side device serving the electronic device 700 and a cooperating network-side device for cooperating in completing the sensing task.

Furthermore, it should be understood that... Figure 7 The functional units in the electronic device 700 shown are logical modules divided according to the specific functions they implement, rather than being used to limit the specific implementation method.

[0110] For example, electronic device 700 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 700 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.

[0111] As an example, electronic device 700 can be a user device in the embodiment of electronic device 400; network-side device in the embodiment of electronic device 700 can be electronic device 400; and collaborative network-side device in the embodiment of electronic device 700 can be a collaborative electronic device in the embodiment of electronic device 400.

[0112] For example, sensing tasks related to electronic device 700 may include UE-based and / or UE-assisted sensing and / or target UE sensing.

[0113] According to embodiments of this disclosure, sensing tasks can be achieved through uplink collaboration between electronic device 700 and multiple network-side devices (network-side devices providing services to electronic device 700 and cooperating network-side devices) based on uplink reference signals.

[0114] As an example, the configuration of the uplink reference signal of electronic device 700 is performed by the network-side device through RRC reconfiguration based on the time-frequency resources and configuration information of the uplink reference signal it has determined.

[0115] As an example, uplink reference signals include uplink channel sounding reference (SRS) or demodulation reference (DMRS).

[0116] This disclosure provides an electronic device 8000 in a communication sensing integrated system according to another embodiment of the present disclosure, comprising: at least one processor; and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured to, through the at least one processor, cause the electronic device 8000 to perform: for a sensing task related to a user equipment, obtaining a sensing result of the sensing task based on sensing data from a network-side device serving the user equipment and sensing data from a cooperating network-side device used to collaboratively complete the sensing task, wherein the user equipment and the network-side device together with the cooperating network-side device perform the sensing task based on an uplink reference signal.

[0117] Figure 8 An exemplary functional block diagram of an electronic device 8000 in a communication-sensing integrated system according to yet another embodiment of the present disclosure is shown.

[0118] like Figure 8As shown, the electronic device 8000 includes: a control unit 8001, which performs control; and a processing unit 8003, which, under the control of the control unit 8001, obtains the perception result of the perception task related to the user equipment based on the perception data from the network-side device providing services to the user equipment and the perception data from the collaborative network-side device used to complete the perception task. The user equipment and the network-side device, together with the collaborative network-side device, perform the perception task based on the uplink reference signal.

[0119] The control unit 8001 and processing unit 8003 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, for example, to store computer program code and data required for the processing circuits to perform processing. Furthermore, it should be understood that... Figure 8 The functional units in the electronic device 8000 shown are logical modules divided according to the specific functions they implement, rather than being used to limit the specific implementation method.

[0120] For example, electronic device 8000 can function as the core network device itself, and may also include external devices such as memory and transceivers (not shown).

[0137] Electronic device 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 Node B (eNB) or gNB (5G base station). eNBs include, for example, macro eNBs and small eNBs. Small eNBs can be eNBs that cover 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 NodeBs and base transceiver stations (BTSs). The base station may include: a subject 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 subject. In addition, various types of electronic devices can operate as base stations by temporarily or semi-persistently performing base station functions.

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.

[0139] [Application examples of base stations]

[0140] (First application example)

[0141] Figure 12 This 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.

[0142] 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 equipment 820 to transmit and receive wireless signals. Figure 12 As shown, the eNB 800 may include multiple antennas 810. For example, the multiple antennas 810 may be compatible with multiple frequency bands used by the eNB 800. Although Figure 12 An example is shown in which the eNB 800 includes multiple antennas 810, but the eNB 800 may also include a single antenna 810.

[0143] The base station equipment 820 includes a controller 821, a memory 822, a network interface 823, and a wireless communication interface 825.

[0144] 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).

[0145] 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.

[0146] 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.

[0147] like Figure 12As shown, 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. Figure 12 As shown, 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 12 An example is shown in which the wireless communication interface 825 includes multiple BB processors 826 and multiple RF circuits 827, but the wireless communication interface 825 may also include a single BB processor 826 or a single RF circuit 827.

[0148] like Figure 4 The electronic device 400 shown is implemented as Figure 12 In the case of the eNB 800 shown, its transceiver 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 perform sensing tasks by executing the functions of the units in the electronic device 400, based on the uplink reference signal, through uplink cooperation between the user equipment and multiple base stations.

[0152] The base station equipment 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 connected to a reference... Figure 13 The controller 821, memory 822, and network interface 823 described are the same.

[0153] 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. In addition to the BB processor 856 being connected to the RF circuitry 864 of the RRH 860 via a connection interface 857, the BB processor 856 is connected to the reference... Figure 13 The described BB processor 826 is the same. Figure 13 As shown, the wireless communication interface 855 may include multiple BB processors 856. For example, the multiple BB processors 856 may be compatible with multiple frequency bands used by the eNB 830. Although Figure 13 An example is shown in which the wireless communication interface 855 includes multiple BB processors 856, but the wireless communication interface 855 may also include a single BB processor 856.

[0154] 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.

[0155] The RRH 860 includes a connectivity interface 861 and a wireless communication interface 863.

[0156] 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.

[0157] The wireless communication interface 863 transmits and receives wireless signals via antenna 840. The wireless communication interface 863 typically includes, for example, RF circuitry 864. RF circuitry 864 may include, for example, a mixer, a filter, and an amplifier, and transmits and receives wireless signals via antenna 840. Figure 13 As shown, the wireless communication interface 863 may include multiple RF circuits 864. For example, the multiple RF circuits 864 may support multiple antenna elements. Although Figure 13 An example is shown in which the wireless communication interface 863 includes multiple RF circuits 864, but the wireless communication interface 863 may also include a single RF circuit 864.

[0158] like Figure 4 The electronic device 400 shown is implemented as Figure 13In the case of the eNB 830 shown, its transceiver 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 perform sensing tasks by executing the functions of the units in the electronic device 400, based on the uplink reference signal, through uplink cooperation between the user equipment and multiple base stations.
