Some examples of the target object are: a human, an animal, a tree, and the like in a natural environment or a man-made environment, an industrial facility, a road, a mobile phone or a vehicle without a wireless communication function or with a closed wireless communication function, a drone with a closed wireless communication function, and the like, which are not limited in the embodiments of the present application.
[0090] The network device of the embodiments of the present application can include an access network device, which is a radio access network (RAN) node (or device) for accessing a terminal device to a wireless network. The access network device includes but is not limited to: a base station (BS), a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a home base station (for example, a home evolutional Node B, or a home Node B, HNB), a baseband unit (BBU), a wireless fidelity (Wi-Fi) access point (AP), a wireless relay node, a wireless backhaul node, a transmission and reception point (TRP; or, a transmission point, TP). The base station is a device deployed in a wireless access network and can provide a wireless communication function, which can also be referred to as a base station device, for example, an evolutional Node B (eNB or e-NodeB) in an LTE system, a Node B (NB), a base station (gNodeB or gNB) in a 5G system, a base station in a next-generation wireless communication system, and the like. The base station can include a BBU and a remote radio unit (RRU). The BBU and the RRU can be placed in different places, for example: RRU pullout, placed in a high traffic area, and the BBU placed in a central machine room. The BBU and the RRU can also be placed in the same machine room. The BBU and the RRU can also be different components under one rack. The base station can be in the following forms: a macro base station, a micro base station (also referred to as a small station), a pico base station, a relay station, an access point, a balloon station, and the like.
[0091] In some deployments of the access network device, the access network device can include a central unit (CU) and / or a distributed unit (DU). Where the access network device includes a CU and a DU, for example, protocol layers of an eNB in an LTE system are split, with some of the functions of the protocol layers being centrally controlled at the CU and the rest or all of the functions of the protocol layers being distributed in the DU and centrally controlled by the CU. In some deployments of the access network device, the CU can also be divided into a CU-control plane (CP) and a CU-user plane (UP), etc. In yet some deployments of the access network device, the access network device can also be an open radio access network (ORAN) architecture, etc. The specific deployment manner of the access network device is not limited in the present application.
[0092] The deployment manner of the access network device is briefly introduced below.
[0093] Manner 1: CU-DU split architecture
[0094] FIG. 2 is a schematic diagram of the CU-DU architecture provided by an embodiment of the present application. As shown in FIG. 2, the access network device is logically divided into one CU and two DUs, and the CU and the DUs are separated. Each DU is connected with the CU through an F1 logical interface. The related operations of the radio link control (RLC) layer, the media access control (MAC) layer, and the physical layer (PHY) are handled by the DU, and the related operations of the radio resource control (RRC) layer, the service data adaptation protocol (SDAP) layer, and the packet data convergence protocol (PDCP) layer are handled by the CU.
[0095] Manner 2: CU-DU-RU split architecture
[0096] In some split architectures, the access network device can be further divided into a CU, a DU, and a radio unit (RU), which is also referred to as an RRU. As shown in FIG. 3, FIG. 3 is a schematic diagram of the CU-DU-RU architecture provided by an embodiment of the present application.
[0097] In the CU-DU separation architecture, the related operations of the PHY layer are handled by the DU; and in the CU-DU-RU separation architecture, part or all of the related operations of the PHY layer are handled by the RU.
[0098] In the CU-DU-RU separation architecture, the interface between the DU and the RU can be referred to as front-haul, the interface between the CU and the DU can be referred to as middle-haul, and the interface between the CU and the core network can be referred to as back-haul.
[0099] Option 3: CU and DU are combined and the whole is separated from the RU
[0100] In some separation architectures, the CU and the DU can not adopt a separate structure, and the CU and the DU are combined and the whole is separated from the RU to form a separation architecture.
[0101] It should be understood that the access network device of the embodiments of the present application does not limit whether the CU and the DU are deployed according to a separation architecture or a combined architecture, i.e., whether the CU and the DU are separated. For ease of understanding, CU&DU in the subsequent text can be understood as the CU and the DU, which can be deployed according to a separation architecture or a combined architecture.
[0102] In different systems, the CU (or CU-CP and CU-UP), DU or RU can also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, the CU can also be referred to as O-CU (open CU), the DU can also be referred to as O-DU, the CU-CP can also be referred to as O-CU-CP, the CU-UP can also be referred to as O-CU-UP, and the RU can also be referred to as O-RU. For ease of description, the CU, DU and RU are described in the present application. Any one of the CU (or CU-CP, CU-UP), DU and RU in the present application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.
[0103] The network device of the embodiments of the present application can also include a core network device (not shown in FIG. 1). The main function of the core network device is to provide user connection, manage users, and complete the bearing of services, and provide an interface to external networks as a bearing network. For example, the core network of the 5G NR system can include an access and mobility management function (AMF) entity, a user plane function (UPF) entity, a session management function (SMF) entity and the like.
[0104] In the above FIG. 1, the CU&DU and the RU of the network device 110, the network device 120, or the network device 130 are separated, and the following describes the sensing scenario 400 of the communication system provided by the embodiments of the present application in combination with FIG. 4. In the sensing scenario 400, the CU&DU of the network device 110 is referred to as CU&DU A, the RU of the network device 110 is referred to as RU 1, the CU&DU of the network device 120 is referred to as CU&DU B, the RU of the network device 120 is referred to as RU 2 and RU 3, the CU&DU of the network device 130 is referred to as CU&DU C, and the RU of the network device 130 is referred to as RU 4.
[0105] If the UE is in the above scenario, when the UE moves from the coverage of the RU 1 to the coverage of the RU 3, the UE can measure the reference signals of the serving cells of the CU&DU B and the CU&DU C, and send the measurement results to the CU&DU A. The CU&DU A determines the target serving cell according to the measurement results, and further determines the target CU&DU corresponding to the target serving cell, for example, determines the CU&DU B as the target CU&DU, sends a handover request to the CU&DU B, and completes the handover process.
[0106] If the target object 160 is in the above scenario, when the target object 160 moves from the coverage of the RU 1 to the coverage of the RU 3, the target CU&DU also needs to be determined, but the target object 160 does not actively send the measurement results of the reference signals of the serving cells of the CU&DU B and the CU&DU C to the CU&DU A, so that the CU&DU A and the CU&DU B or the CU&DU C cannot realize handover, thereby affecting the continuity and reliability of the sensing of the target object 160.
[0107] In order to solve the above problems, the embodiments of the present application provide two sensing communication methods that can negotiate between multiple CU&DUs to track and sense the target object. The above CU&DU is also referred to as a network device unit or a baseband unit, and the RU is also referred to as a radio frequency unit.
[0108] In the first perception communication method provided in the embodiments of the present application, the current network device unit determines at least one network device unit capable of receiving the echo signal of the perception signal by interacting with the at least one network device unit, and instructs the wireless unit managed by the current network device unit to send the perception signal. Correspondingly, the at least one network device unit also instructs the wireless unit managed by the at least one network device unit to receive the echo signal of the perception signal. Thus, one network device unit can be determined from the at least one network device unit to continue to perceive the target object, and the continuity and reliability of perception are achieved. The current network device unit can also be referred to as a source network device unit, the at least one network device unit capable of receiving the echo signal of the perception signal can be referred to as a candidate network device unit, and the one network device unit determined from the at least one network device unit can be referred to as a target network device unit.
[0109] In the second perception communication method provided in the embodiments of the present application, the network device with the perception information processing function (which can be an existing network device such as an existing base station or core network device, or a newly added network device such as a newly added base station or core network device, and is different from the network device of the current network device unit and the network device of the candidate network device unit) instructs the current network device unit to make the wireless unit managed by the current network device unit send the perception signal, and instructs the candidate network device unit to make the wireless unit managed by the candidate network device unit receive the echo signal of the perception signal. Thus, one network device unit can be determined from the candidate network device unit to continue to perceive the target object, and the continuity and reliability of perception are achieved.
[0110] The second perception communication method is different from the first perception communication method in that the second perception communication method uses the network device with the perception information processing function (i.e., a device different from the network device unit performing the perception task) to complete the information processing of the current network device unit.
[0111] Next, the first perception communication method provided in the embodiments of the present application will be described in detail in combination with FIG. 5 and FIG. 6.
[0112] FIG. 5 shows an exemplary flowchart of a perception communication method 500 provided in the embodiments of the present application. The perception communication method 500 can be applied to the communication system 100 shown in FIG. 1, and can also be applied to other communication systems, which are not limited in the embodiments of the present application. The method 500 includes the following steps:
[0113] S510, the second network device unit sends first information to at least one network device unit, and correspondingly, the at least one network device unit receives the first information, the first information being used to request to receive the echo signal on the first physical resource for perception device switching.
[0114] In the embodiments of this application, "sending information to a network device unit" or a similar description can be understood as the destination of the information being a network device unit, and may include sending information directly or indirectly to a network device unit. "Receiving information from a network device unit" or a similar description can be understood as the source of the information being a network device unit, and may include receiving information directly or indirectly from a network device unit. Information may undergo necessary processing between the source and destination of information transmission, but the destination can understand valid information from the source. Similar expressions in this application can be understood in a similar way, and will not be elaborated further here.
[0115] For example, the second network device unit may be the aforementioned CU&DU A, and at least one network device unit may be the aforementioned CU&DU B and / or CU&DU C.
[0116] For example, the first information may include information indicating one or more of the following: time-domain resources, frequency-domain resources, spatial-domain resources, code-domain resources, the number of repetitions of the sensed signal, the period of the sensed signal, or time synchronization information. The time-domain resources may include a system frame number (SFN), a slot, a sub-slot, or a symbol, etc. The frequency-domain resources may include bandwidth, subcarrier spacing, etc. The spatial-domain resources may include beam direction information, etc. The code-domain resources may include a code sequence used to generate the sensed signal, etc. The number of repetitions of the sensed signal may indicate how many times the sensed signal will be transmitted, and may include a specific value. The period of the sensed signal may indicate the time interval for transmitting the sensed signal, etc., and the time interval may include a slot, a sub-slot, or a symbol, etc. The time synchronization information, used to synchronize two network device units, may include time information corresponding to the air interface system frame number (SFN) / slot / symbol ID, and the time information may be Coordinated Universal Time (UTC).
[0117] In one possible implementation, the first information includes both time-domain resources and spatial resources within the first physical resources. At least one network device unit can determine the first physical resources based on the first information and predefined frequency-domain resources. It should be understood that either the time-domain resources or the spatial resources can be predefined.
[0118] In another possible implementation, the first information includes time-domain resources, frequency-domain resources, and spatial-domain resources of the first physical resources. At least one network device unit can determine the first physical resources based on the first information.
[0119] In another possible implementation, the first information includes time-domain resources, frequency-domain resources, and spatial-domain resources of the first physical resource, as well as the number of repetitions of the sensing signal and the period of the sensing signal. At least one network device unit can determine the first physical resource based on the first information and learn the number of times the sensing signal is transmitted on the first physical resource and the time interval between transmissions, etc.
[0120] In another possible implementation, the first information includes time-domain resources, frequency-domain resources, and spatial-domain resources of the first physical resources, as well as time synchronization information. At least one network device unit can determine the first physical resources based on the first information, simultaneously acquire the time synchronization information, and complete time synchronization between at least one network device unit and a second network device unit based on the time synchronization information.
[0121] In another possible implementation, the aforementioned first information includes time-domain resources, frequency-domain resources, and spatial-domain resources in the first physical resources, as well as the number of repetitions of the sensing signal, the period of the sensing signal, and time synchronization information.
[0122] It should be understood that the above is merely an example to illustrate the content included in the first piece of information, and those skilled in the art can make changes according to the actual network environment and application scenario.
[0123] For example, the first information may directly carry one or more of the following: time-domain resources, frequency-domain resources, spatial-domain resources, code-domain resources, the number of repetitions of the sensed signal, the period of the sensed signal, or time synchronization information. It may also carry index information for one or more of the above. It should be understood that the correspondence between the index information and the above one or more may be predefined. The second network device unit and at least one network device unit may also predefine one or more of the above. The first information may carry indication information, such as 1. When the indication information is 1, it indicates the use of the predefined one or more of the above.
[0124] For example, the first information may be called a sensing handover (HO) request, or may have other names, which are not limited in this application embodiment.
[0125] It should be understood that the first physical resource refers to the physical resource for the first wireless unit, managed by the second network device unit, to transmit sensing signals, and also the physical resource for the second wireless unit, managed by at least one network device unit, to receive echo signals of the sensing signals. There may be a time delay between the physical resource for the first wireless unit to transmit sensing signals and the physical resource for the second wireless unit to actually receive echo signals, but this delay is negligible, or at least one network device unit can correct it itself based on network characteristics; this application embodiment does not limit this. Therefore, in this application, the physical resource for the first wireless unit to transmit sensing signals is equivalent to the physical resource for the second wireless unit to receive echo signals.
[0126] S520, at least one network device unit sends second information to a second network device unit, and correspondingly, the second network device unit receives the second information, which is used to indicate acceptance of receiving echo signals on the first physical resource for sensing device switching.
[0127] It should be understood that after a second network device unit sends first information to at least one network device unit, only some of the network device units may receive the first information and then send second information. In this description, "at least one network device unit sending second information to a second network device unit" includes the scenario where all or some of the at least one network device unit sends second information to the second network device unit. Similar descriptions in the following text can be understood as all or some of the network device units sending or receiving the information.
[0128] For example, the second information may include acknowledgment information, such as ACK.
[0129] For example, the second information may be called a sensing HO request ACK, or it may have other names, which are not limited in this application embodiment.
[0130] S530, the second network device unit sends third information to the first wireless unit, and correspondingly, the first wireless unit receives the third information, which is used to instruct the transmission of the first sensing signal on the first physical resource.
[0131] For example, the third information is similar to the first information and can be understood by reference.
[0132] It should be understood that if the first information contains time synchronization information, the third information may not include time synchronization information, and other time synchronization methods may be used between network device units and wireless units.
[0133] S540, at least one network device unit sends a fourth message to the second wireless unit, and correspondingly, the second wireless unit receives the fourth message, which is used to indicate that an echo signal is received on the first physical resource.
[0134] Specifically, after receiving the first information, at least one network device unit can determine the first physical resource and then send the fourth information to the second wireless unit to instruct the second wireless unit to receive the echo signal on the first physical resource.
[0135] For example, the fourth piece of information is similar to the third piece of information and can be understood by reference.
[0136] In the sensing communication method of this application embodiment, a second network device unit requests at least one network device unit to receive an echo signal on a first physical resource. At least one network device unit instructs the second network device unit to accept receiving the echo signal on the first physical resource. The second network device unit instructs the first wireless unit it manages to send a first sensing signal on the first physical resource, so that the second wireless unit managed by at least one network device unit can receive the echo signal on the first physical resource. Thus, multiple network device units can negotiate to track and sense the target object, thereby achieving continuity and reliability of sensing.
[0137] For example, a network device unit that receives echo signals on a first physical resource can be used to switch from a second network device unit to continue sensing the target object. Alternatively, based on the reception of the echo signals, the second network device unit can determine the target sensing device from at least one network device unit, switch from the second network device unit to the target sensing device, and continue sensing the target object.
[0138] As an optional embodiment, as shown in FIG5, the sensing communication method 500 further includes: S550, after receiving the third information, the first wireless unit sends a first sensing signal on the first physical resource according to the third information. The first sensing signal is reflected or scattered by the target object during propagation to generate a first echo signal. Correspondingly, S560, the second wireless unit receives the first echo signal; S570, the second wireless unit sends the first echo signal to at least one network device unit. Correspondingly, at least one network device unit receives the first echo signal; S580, at least one network device unit sends a fifth information to the second network device unit according to the first echo signal. Correspondingly, the second network device unit receives the fifth information, which is used to indicate the reception status of the first echo signal; S590, the second network device unit sends a sixth information to the first network device unit among the at least one network device unit according to the fifth information. Correspondingly, the first network device unit receives the sixth information, which is used to indicate that the target sensing device is the first network device unit.
[0139] As an optional embodiment, the fifth information includes one or more of the following: the echo intensity of the first echo signal; probability information of successful detection of the target object obtained based on the first echo signal; information obtained based on the first echo signal to indicate that no target object was detected; information to indicate that detection is in progress; information to request an increase in the transmission power of the sensing signal; or information to request a change in the physical resources for transmitting the sensing signal.
[0140] For example, each of the at least one network device unit can calculate the signal strength of the first echo signal to obtain the echo strength, and carry the echo strength in the fifth information. If the second network device unit determines that the echo strength is greater than a threshold, the network device unit can be considered as a target sensing device; or each of the at least one network device unit can obtain the probability information of successful target object sensing based on the signal strength, signal-to-noise ratio, and other information of the first echo signal, and carry the probability information in the fifth information. If the second network device unit determines that the probability is greater than a threshold, the network device unit can be considered as a target sensing device; or each of the at least one network device unit can obtain the information of undetected target object based on the signal strength, signal-to-noise ratio, and other information of the first echo signal, and carry the information in the fifth information. The second network device unit can consider that the network device unit cannot be a target sensing device; or at least one network device Each network device unit in the unit can obtain the information of the sensing process based on the signal strength, signal-to-noise ratio, and other information of the first echo signal, and carry this information in the fifth information. The second network device unit can continue to wait to receive the fifth information again or notify the network device unit to continue sending the fifth information. If there are other network device units that can be used as target sensing devices, it can also be considered that the network device unit cannot be used as a target sensing device. Alternatively, if each network device unit in at least one of the network device units does not receive the first echo signal or the first echo signal is unclear, the fifth information carries information for requesting an increase in the transmission power of the sensing signal or information for requesting a change in the physical resources for transmitting the sensing signal. The second network device unit can instruct the first wireless unit to increase the transmission power of the first sensing signal or change the physical resources for transmitting the sensing signal. If there are other network device units that can be used as target sensing devices, it can also be considered that the network device unit cannot be used as a target sensing device.
[0141] It should be understood that the above are merely examples illustrating the content of the fifth piece of information and the method of determining the target sensing device. Those skilled in the art can make changes according to the actual network environment and application scenario.
[0142] For example, the fifth message may be called a HO notification message, or may have other names, which are not limited in this application embodiment.
[0143] In the sensing communication method of this application embodiment, the second network device unit determines the first network device unit as the target sensing device based on the reception of the first echo signal. The first network device unit that is more suitable for sensing the target object can be determined so that the user can switch from the second network device unit to the first network device unit. This allows for tracking and sensing of the target object, further realizing the continuity and reliability of sensing.
[0144] As an optional embodiment, the sensing communication method 500 further includes: a second network device unit sending seventh information to a third network device unit among at least one network device unit according to the fifth information; correspondingly, the third network device unit receives the seventh information, which is used to indicate that the target sensing device is not the third network device unit. The process for determining the third network device unit can refer to the process for determining the first network device unit in the above embodiments, and will not be repeated here.
[0145] In the sensing communication method of this application embodiment, while the second network device unit determines that the first network device unit is the target sensing device based on the reception of the first echo signal, it can send seventh information to other third network device units that are not the target sensing devices, so that the third network device unit can release the wireless resources of the wireless unit based on the seventh information, thereby saving wireless resources.
[0146] As an optional embodiment, the sensing communication method 500 further includes: sending tenth information to a first wireless unit, the tenth information being used to indicate that the transmission of the first sensing signal should be stopped.
[0147] In the sensing communication method of this application embodiment, after the second network device unit determines that the first network device unit is the target sensing device based on the reception of the first echo signal, the first network device unit can track and sense the target object to achieve the continuity and reliability of sensing. At this time, the first wireless unit managed by the second network device unit does not need to continue to act as a sensing wireless unit. Therefore, the second network device unit sends tenth information to the first wireless unit to indicate that the first sensing signal should be stopped. The first wireless unit can release wireless resources, thus saving wireless resources.
[0148] As an optional embodiment, the number of second wireless units is multiple, the number of first echo signals is multiple, and the sensing communication method 500 further includes: selecting one wireless unit as a target wireless unit from the multiple second wireless units according to the multiple first echo signals; sending eleventh information to the target wireless unit, the eleventh information being used to instruct the transmission of sensing signals and the reception of echo signals; and sending twelfth information to the remaining wireless units among the multiple second wireless units other than the target wireless unit, the twelfth information being used to instruct the cessation of transmission of sensing signals and the cessation of reception of echo signals.
[0149] For example, if the first network device unit is determined to be the target sensing device, it is further necessary to determine the target wireless unit from among the plurality of second wireless units. The first network device unit can select one wireless unit as the target wireless unit from among the plurality of second wireless units based on the plurality of first echo signals. For example, the second wireless unit whose transmitted first echo signal has the largest echo intensity can be selected as the target wireless unit. Alternatively, the first network device unit can also retransmit the second sensing signal to the plurality of second wireless units respectively, receive the plurality of second echo signals from the plurality of second wireless units, and select one wireless unit as the target wireless unit from among the plurality of second wireless units based on the plurality of second echo signals.
[0150] It should be understood that the process of determining the target wireless unit described above can also be implemented by the second network device unit. The second network device unit can select one wireless unit from multiple second wireless units as the target wireless unit based on the multiple first echo signals fed back by the first network device unit, and indicate the target wireless unit to the first network device unit.
[0151] In the sensing communication method of this application embodiment, if the number of second wireless units managed by the target sensing device is multiple, it is necessary to continue to confirm the target wireless unit, and use the target wireless unit to send sensing signals and receive echo signals to continue to sense the target object, so as to achieve the continuity and reliability of sensing; at the same time, it is also possible to instruct the remaining wireless units other than the target wireless unit to stop sending sensing signals and stop receiving echo signals in order to release wireless resources.
[0152] As an optional embodiment, prior to S510, the sensing communication method 500 further includes: a second network device unit sending an eighth message to at least one network unit, wherein at least one network unit receives the eighth message, the eighth message being used to request the reception of an echo signal on a second physical resource for sensing device switching; and at least one network unit sending a ninth message to the second network device unit, wherein the second network device unit receives the ninth message, the ninth message being used to indicate refusal to receive an echo signal on the second physical resource for sensing device switching.
[0153] For example, the eighth piece of information can be called a perception switching request, which can be understood by referring to the first piece of information. The second physical resource and the first physical resource contain the same type of information, but the content is different.
[0154] The ninth message can be called sensing HO preparation failure, or it can have other names, which are not limited to the embodiments of this application.
[0155] For example, the ninth information also carries one or more of the following: information indicating that the sensing function is not supported; information indicating that the sensing function is not enabled; or information indicating that the second physical resource is unavailable.
[0156] For example, the ninth information also carries information for indicating the first physical resource, for suggesting the use of the first physical resource for sensing handover.
[0157] For example, the second network device unit sends an eighth message to at least one network device to request the reception of an echo signal on a second physical resource. If at least one network device (partially or entirely) refuses to receive the echo signal on the second physical resource, it sends a ninth message to the second network device unit. The second network device unit can obtain the reason for the refusal from the ninth message, such as the network device unit not supporting the sensing task or not having started the sensing task; or the second physical resource being unavailable, such as the time slot of the second physical resource conflicting with the time slot used for communication services. The second network device unit can also obtain a set of recommended physical resources from the ninth message, select a first physical resource from the set of recommended physical resources, and return to S510 to send the first message to at least one network device. It should be understood that if the ninth message does not carry a set of physical resources, the second network device unit, after receiving the ninth message, can determine the first physical resource on its own or select the first physical resource from a predefined set of physical resources, and return to S510 to send the first message to at least one network device.
[0158] In the sensing communication method of this application embodiment, if at least one network device refuses to receive echo signals on the second physical resource, the second network device unit can reselect the physical resource and continue to send the first information to at least one network device, readjust the physical resources for sending sensing signals and receiving echo signals, and increase the probability of obtaining the target sensing device.
[0159] As an optional embodiment, the sensing communication method 500 further includes: if the second network device unit fails to identify the target sensing device based on the fifth information, the second network device unit sends a thirteenth information to the first wireless unit, the thirteenth information being used to instruct the first wireless unit to increase the transmission power of the first sensing signal, and returns to step S550 to continue transmitting the first sensing signal.
[0160] In the sensing communication method of this application embodiment, if the target sensing device is not identified, the transmission power of the first sensing signal can be increased to increase the probability of obtaining the target sensing device.
[0161] As an optional embodiment, the sensing communication method 500 further includes: if the second network device unit fails to determine the target sensing device based on the fifth information, the second network device unit replaces the first physical resource with the third physical resource and returns to step S510 to continue communicating with at least one network device.
[0162] In the sensing communication method of this application embodiment, if the second network device unit fails to determine the target sensing device based on the fifth information, it readjusts the physical resources for sending sensing signals and receiving echo signals to increase the probability of obtaining the target sensing device.
[0163] Figure 6 shows a schematic flowchart of the perceptual communication method 600 in the scenario shown in Figure 4.
[0164] When CU&DU A detects that a target object is about to leave the coverage area of RU1 based on the echo signal of RU1, CU&DU A identifies CU&DU B and CU&DU C, and interacts with CU&DU B and CU&DU C to identify the target CU&DU and the target RU. Specifically, as shown in Figure 6, this sensing communication method 600 can be applied to the communication system 100 shown in Figure 1, and can also be applied to other communication systems, but the embodiments of this application are not limited thereto. The method 600 includes the following steps:

[0168] S640, CU&DU B sends a handover request confirmation to CU&DU A (equivalent to the second information mentioned above), and CU&DU C sends a handover request confirmation to CU&DU A. Correspondingly, CU&DU A receives the handover request confirmation from CU&DU B and the handover request confirmation from CU&DU C.

The designated physical resource is equivalent to the first physical resource mentioned above.
[0170] S650, CU&DU A sends first control information (equivalent to the third information mentioned above) to RU 1. Correspondingly, RU 1 receives the first control information and sends a first sensing signal according to the first control information.
[0171] S660, CU&DU B sends second control information to RU 2 and RU 3.

[0176] S6110, CU&DU A sends the fourth control information (relative to the seventh information mentioned above) to CU&DU C, and CU&DU C receives the fourth control information accordingly; S6150, after receiving the fourth control information, CU&DU C sends the eighth control information to RU 4, instructing RU 4 to stop receiving echo signals, and RU 4 receives the eighth control information and stops receiving echo signals accordingly.
[0177] S6120, CU&DU A sends the fifth control information (relative to the tenth information mentioned above) to RU 1. Correspondingly, RU 1 receives the fifth control information and stops sending sensing signals.

[0180] The second sensing communication method provided in the embodiments of this application will be described in detail below with reference to Figure 7.
[0181] Figure 7 shows an exemplary flowchart of another sensing communication method 700 provided in this application embodiment. This sensing communication method 700 can be applied to the communication system 100 shown in Figure 1, and can also be applied to other communication systems; this application embodiment does not limit its application to this. In the second sensing communication method, a network device with sensing information processing capabilities is introduced, which can be called a sensing unit (SU) or a serving unit (SU). This application does not specifically limit the name of the network device with sensing information processing capabilities. This network device with sensing information processing capabilities can handle sensing-related functions, such as selecting physical resources for sensing signals, determining whether a target object appears based on the echo signal of the sensing signal, and identifying the target sensing device, etc. The network device with sensing information processing capabilities can be an existing network device, such as an existing base station or core network device with added sensing-related functions, or it can be a newly added network device, such as a newly added base station or core network device to implement sensing-related functions. It should be understood that the network device unit in method 700 below does not have the ability to process echo signals, or has only a partial ability to process echo signals, such as only being able to obtain the echo intensity of the echo signal. This application embodiment does not limit this. Method 700 includes the following steps:
[0182] S710, a network device with sensing information processing capabilities sends first information to a first network device unit. Correspondingly, the first network device unit receives the first information, which instructs the first sensing signal to be transmitted on the first physical resource. The first network device unit instructs the managed radio units to transmit the first sensing signal on the first physical resource according to the first information. The first network device unit is the network device unit currently providing sensing services to the target object.
[0183] S720, a network device with sensing information processing function sends second information to at least one second network device unit, and correspondingly, at least one second network device unit receives the second information, which is used to indicate that an echo signal is received on the first physical resource.
[0184] For example, the first network device unit can be the CU&DU A described above, and at least one second network device unit can be the CU&DU B and / or CU&DU C described above, as can be understood with reference to the foregoing embodiments.
[0185] The first physical resource can be referred to in the aforementioned embodiments.
[0186] For example, the first or second information includes information for indicating one or more of the following: time domain resources, frequency domain resources, spatial domain resources, code domain resources, the number of repetitions of the sensed signal, the period of the sensed signal, or time synchronization information.
[0187] According to the foregoing embodiments, there may be a time delay between the physical resources for sending sensing signals and the physical resources for receiving echo signals, but this time delay can be ignored or corrected according to network characteristics. Therefore, the first information and the second information can be similar, and can also be understood with reference to the first information, the third information and the fourth information in the foregoing embodiments.
[0188] S730, at least one second network device unit sends a fourth message to the wireless unit, and correspondingly, the wireless unit receives the fourth message, which is used to indicate that an echo signal is received on the first physical resource.
[0189] Similarly, the fourth information can be understood with reference to the fourth information in the foregoing embodiments.
[0190] S740, the wireless unit sends a first echo signal corresponding to the first sensing signal to at least one second network device unit, and correspondingly, at least one second network device unit receives the first echo signal.
[0191] Specifically, after receiving the fourth information, the wireless unit receives the first echo signal on the first physical resource and sends the first echo signal to the corresponding second network device unit.
[0192] S750, at least one second network device unit sends third information to a network device with sensing information processing function, and correspondingly, the network device with sensing information processing function receives the third information, which is used to indicate the first echo signal.
[0193] For example, at least one second network device unit may send the first echo signal to the network device for sensing, or may perform simple processing on the first echo signal, such as obtaining the echo intensity, and then send the first echo signal and the echo intensity to the network device for sensing, or may send the echo intensity to the network device for sensing separately, depending on the performance of the at least one second network device unit.
[0194] In the sensing communication method of this application embodiment, a network device with sensing information processing function can instruct a first network device unit to send a sensing signal to a wireless unit managed by the first network device unit, and simultaneously instruct at least one second network device unit to receive an echo signal to track and sense the target object, thereby achieving continuity and reliability of sensing.
[0195] For example, a second network device unit that receives echo signals on the first physical resource can be used to switch from the first network device unit to the second network device unit to continue sensing the target object. Alternatively, based on the reception of the echo signals, a target sensing device can be determined from at least one second network device unit, and the user can switch from the first network device unit to the target sensing device to continue sensing the target object. It should be understood that in the embodiments of this application, the first network device unit is the source network device unit, and the selected second network device unit is the target network device unit.
[0196] As an optional embodiment, the sensing communication method 700 further includes: S760, a network device with sensing information processing function sends fifth information to a third network device unit among at least one second network device unit according to the third information, and correspondingly, the third network device unit receives the fifth information, which is used to indicate that the target sensing device is the third network device unit; S770, the third network device unit sends sixth information to a wireless unit, and correspondingly, the wireless unit receives the sixth information, which is used to indicate the transmission of a sensing signal and the reception of an echo signal.
[0197] Specifically, after receiving the third information, if the third information is a first echo signal, the network device with sensing information processing capability processes the first echo signal to obtain one or more of the following: the echo intensity of the first echo signal; probability information of successful sensing of the target object obtained based on the first echo signal; information indicating that no target object has been detected obtained based on the first echo signal; information indicating that sensing is in progress obtained based on the first echo signal; information on increasing the transmission power of the sensing signal obtained based on the first echo signal, such as the required transmission power; or information on changing the physical resources for transmitting the sensing signal obtained based on the first echo signal. Then, the network device with sensing information processing capability sends the fifth information to the third network device unit according to the processed information. The third network device unit controls the wireless unit to transmit the sensing signal and receive the echo signal to continue sensing the target object according to the fifth information. This process can be understood with reference to the foregoing embodiments. If the third information is the echo intensity, the network device can directly send the fifth information to the third network device unit according to the echo intensity.
[0198] In the sensing communication method of this application embodiment, the network device with sensing information processing function determines the third network device unit as the target sensing device based on the reception of the first echo signal. This can determine the network device unit that is more suitable for sensing the target object as the target sensing device, thereby further realizing the continuity and reliability of sensing.
[0199] If the third network device unit includes multiple wireless units, the third information carries information for indicating multiple first echo signals corresponding to the multiple wireless units, and the fourth information also carries information for indicating a target wireless unit among the multiple wireless units. In this case, after determining the target sensing device, if the target sensing device controls multiple wireless units, the network device with sensing information processing capabilities can also determine the target wireless unit based on the multiple first echo signals corresponding to the multiple wireless units and indicate it to the target sensing device, for example, by sending the identification information of the target wireless unit to the target sensing device. It should be understood that if the network device with sensing information processing capabilities cannot determine the target wireless unit, the third network device unit can still determine the target wireless unit. The process of determining the target wireless unit can be understood with reference to the foregoing embodiments.
[0200] As an optional embodiment, the sensing communication method 700 further includes: a network device with sensing information processing function sending seventh information to a fourth network device unit among at least one second network device unit according to third information, wherein the fourth network device unit receives the seventh information, which is used to indicate that the target sensing device is not the fourth network device unit; the fourth network device unit sending eighth information to a wireless unit, which receives the eighth information, which is used to indicate to stop sending sensing signals and stop receiving echo signals.
[0201] In the sensing communication method of this application embodiment, a network device with sensing information processing function determines a third network device unit as a target sensing device based on the reception of the first echo signal, and sends seventh information to other network device units that are not target sensing devices. These network device units release wireless resources based on the seventh information, thus saving wireless resources.
[0202] It should be understood that when the first network device unit senses a target object, the managed wireless unit sends a first sensing signal and receives a first echo signal, and then sends the first echo signal back to the first network device unit. Correspondingly, the first network device unit receives the first echo signal and sends it back to a network device with sensing information processing capabilities. If the network device with sensing information processing capabilities receives the first echo signal and determines, based on the first echo signal, that sensing device switching is required (e.g., the target object is moving towards the edge of the coverage area), the network device with sensing information processing capabilities sends first information to the first network device unit and second information to at least one second network device unit to perform sensing device switching.

Based on these examples, it is understood that network device units and network devices, in order to achieve the aforementioned functions, include corresponding hardware structures and / or software modules for performing each function.
