Description

Communication method and related apparatus

[0001] This application claims priority from the Chinese patent application No. 202410745830.0 filed on June 7, 2024, and entitled "Communication method and related apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, and in particular, to a communication method and related apparatus. BACKGROUND

[0003] In addition to communication capability, a wireless communication device can also have sensing capability. Exemplarily, a wireless communication device with sensing capability (hereinafter referred to as a sensing device for convenience of description) can obtain the situation of the surrounding environment by sending a reference signal for sensing and receiving echo information, for example, to determine whether a specific target appears in the surrounding environment.

[0004] Currently, in order to be able to timely sense the changes in the surrounding environment of the communication device, so as to have a low probability of missing newly appearing objects in the environment, the sensing device will densely and continuously send the reference signal for sensing. However, this way of continuously and periodically sending the reference signal for sensing is not flexible enough and it is difficult to accurately sense the target. SUMMARY

[0005] The present application provides a communication method and related apparatus to flexibly adjust the sending mode of the reference signal for sensing.

[0006] In a first aspect, the present application provides a communication method, which can be applied to a third logical unit. For example, the third logical unit can be a distributed unit (DU), or other units that can be used to process layer 2 signals and physical layer signals, or it can also be a component (such as a processor, circuit, chip or chip system, etc.) configured in the third logical unit, or it can also be software capable of realizing all or part of the functions of the third logical unit, and the present application does not limit this.

[0007] Exemplarily, the method comprises: receiving first information, the first information being used to indicate a first mode corresponding to a first echo signal and / or to indicate a beam identifier corresponding to the first echo signal, the first echo signal being a signal reflected by a target from a first reference signal; in response to the first information, sending second information, the second information being used to indicate that a first logical unit activates a second mode.

[0008] It can be understood that the first mode corresponding to the first echo signal can include information for instructing the first logical unit to transmit the first reference signal or receive the first echo signal in a scanning manner or in a single direction manner, the first reference signal being transmitted by the first logical unit.

[0009] Wherein, transmitting the reference signal in a scanning manner means transmitting the reference signal in different directions, and receiving the echo signal in a scanning manner means receiving the echo signal from different directions; transmitting the reference signal in a single direction manner means transmitting the reference signal in the same direction, and receiving the signal in a single direction manner means receiving the echo signal from the same direction.

[0010] Optionally, the first mode and the second mode can be predefined or indicated by the third logical unit.

[0011] Based on the technical solution, the third logical unit can determine the direction of the target appearance by receiving the information for indicating the first mode corresponding to the first echo signal and / or the beam identifier corresponding to the first echo signal, and then transmit the information for instructing the first logical unit to activate the second mode based on the determined direction of the target appearance, so that the first logical unit can transmit the reference signal based on the second mode to perceive the target. It can be seen that the method provided by the application can dynamically adjust the transmission mode of the reference signal according to the received echo, and flexibly adjust the transmission mode of the reference signal for perception, thereby effectively improving the perception accuracy of the target.

[0012] Optionally, the second mode can include information for indicating the transmission mode of the second reference signal, and the transmission mode of the second reference signal can be a single direction manner. In other words, the second mode can include information for indicating that the transmission mode of the second reference signal is a single direction manner, the second reference signal being transmitted by the first logical unit.

[0013] Optionally, the first information can be from the first logical unit or from the second logical unit.

[0014] In a possible implementation, the first information is from the first logical unit. That is, the first echo signal is received by the first logical unit.

[0015] Optionally, the beam identifier corresponding to the first echo signal is at least one beam identifier of the first reference signal, the at least one beam identifier of the first reference signal can determine the beam direction of transmitting the first reference signal, or in other words, can determine which beam of the reference signal transmitted by the first logical unit is used to transmit the first echo signal, or in other words, can determine the geographic area where the target appears.

[0016] Optionally, the first mode corresponding to the first echo signal is a transmission mode of the first reference signal, and the first mode includes information indicating that the transmission mode of the first reference signal is a scanning mode; and the second mode includes information indicating that the transmission mode of the second reference signal is a single-direction mode.

[0017] Based on this, the first logic unit transmits the first reference signal in the scanning mode, and after receiving the echo signal of the first reference signal reflected by the target, the third logic unit determines that the first logic unit transmits the second reference signal in the single-direction mode to sense the same target based on the information related to the echo signal. This way of adjusting the transmission mode of the reference signal from the scanning mode to the single-direction mode, i.e., adjusting the transmission direction of the reference signal from multiple directions to a single direction, can effectively reduce the cost of air interface resources and the power consumption of sensing.

[0018] With reference to the first aspect, in some implementations of the first aspect, before the first information is received, the method further includes: transmitting third information, the third information being used to instruct the first logic unit to activate the first mode.

[0019] Alternatively, the third information is used to instruct the first logic unit to transmit the reference signal in the first mode.

[0020] Based on this, the way of instructing the first logic unit to transmit the first reference signal in the scanning mode can effectively avoid missing the target appearing in the environment.

[0021] In another possible implementation, the first information is from the second logic unit. That is, the first echo signal is received by the second logic unit.

[0022] Optionally, the beam identifier corresponding to the first echo signal is a beam identifier of the first echo signal received by the second logic unit, and the beam identifier of the first echo signal is used to determine the beam direction of receiving the first echo signal, or in other words, to determine the geographic area where the target appears.

[0023] Optionally, the first information is further used to indicate at least one beam identifier of the first reference signal corresponding to the first echo signal. The description of the at least one beam identifier of the first reference signal can be referred to the foregoing description, which is not repeated here.

[0024] Optionally, the first mode corresponding to the first echo signal is a transmission mode of the first reference signal, and the first mode includes information indicating that the transmission mode of the first reference signal is a scanning mode; and the second mode includes information indicating that the transmission mode of the second reference signal is a single-direction mode.

[0025] Based on this, the first logic unit transmits the first reference signal in a scanning manner, after the second logic unit receives the echo signal of the target reflected by the first reference signal, the third logic unit determines that the first logic unit transmits the second reference signal in a single direction manner based on the information related to the echo signal, so as to perceive the same target. The manner of adjusting the transmission of the reference signal from the scanning manner to the single direction manner, i.e., the manner of adjusting the transmission of the reference signal from the multiple directions to the single direction, can effectively reduce the overhead of the air interface resource and reduce the power consumption of the perception.

[0026] With reference to the first aspect, in some implementations of the first aspect, the method further includes: in response to the first information, transmitting fourth information, the fourth information being used to instruct the second logic unit to activate a third mode, the third mode including information used to indicate that the receiving manner of the second echo signal is a single direction manner, the second echo signal being a signal of the second reference signal reflected by a target.

[0027] Optionally, the receiving beam direction of the second echo signal is the same as or similar to the transmitting beam direction of the second reference signal.

[0028] With reference to the first aspect, in some implementations of the first aspect, before the receiving of the first information, the method further includes: transmitting fifth information, the fifth information being used to instruct the second logic unit to activate the first mode.

[0029] Optionally, before the receiving of the first information, the method further includes: transmitting ninth information, the ninth information being used to instruct the first logic unit to activate a fifth mode, the fifth mode including information used to indicate that the transmitting manner of the first reference signal is a scanning manner.

[0030] Optionally, the receiving period of the first echo signal is different from the transmitting period of the first reference signal.

[0031] Based on the fifth information and the ninth information, the receiving beam of the echo signal corresponding to the transmitting beam of the reference signal can be obtained.

[0032] With reference to the first aspect, in some implementations of the first aspect, the method further includes: transmitting sixth information, the sixth information being used to instruct the second logic unit to activate a fourth mode, the fourth mode including information used to indicate that the transmitting manner of the third reference signal is a single direction manner, the beam direction of the third reference signal corresponding to the beam direction of the second reference signal.

[0033] The beam direction of the third reference signal corresponds to the beam direction of the second reference signal, which means that the geographical area corresponding to the beam direction of the third reference signal is the same as the geographical area corresponding to the beam direction of the second reference signal.

[0034] With reference to the first aspect, in some implementations of the first aspect, the method further includes: sending seventh information, the seventh information being used for configuring multiple modes, the multiple modes including the first mode and the second mode, each of the multiple modes including at least one of the following: a number of times of sending a signal, a sequence format of generating the signal, a time domain position of the signal, or a frequency domain resource of the signal.

[0035] The signal can be a reference signal or a backhaul signal. If the signal is a backhaul signal, the number of times of sending the signal can be replaced by the number of times of receiving the signal.

[0036] Optionally, the time domain position of the signal includes a sending period of the signal, a starting time domain position of the signal, or a duration of the signal.

[0037] Similarly, if the signal is a backhaul signal, the sending period of the signal can be replaced by the receiving period of the signal.

[0038] Optionally, the multiple modes further include a third mode, a fourth mode, and a fifth mode.

[0039] With reference to the first aspect, in some implementations of the first aspect, the method further includes: sending eighth information, the eighth information being used for instructing the first logic unit to deactivate the first mode and / or the second mode.

[0040] Based on this, the first logic unit does not need to continue to send the reference signal in the first mode and / or the second mode, effectively reducing the cost of air interface resources.

[0041] In the second aspect, the present application provides a communication method, which can be applied to a first logic unit. For example, the first logic unit can be a radio unit (RU), or other units that can be used to process physical layer signals, or a component (such as a processor, a circuit, a chip, or a chip system) configured in the first logic unit, or software capable of realizing all or part of the functions of the first logic unit, and the present application does not limit this.

[0043] The first mode corresponding to the first echo signal is a mode of the first reference signal, and the mode of the first reference signal can comprise information used for indicating that the first logic unit sends the first reference signal in a scanning manner or in a single-direction manner. In the present application, the first logic unit can send the first reference signal in a scanning manner, that is, the first mode comprises information used for indicating that the sending manner of the first reference signal is a scanning manner.

[0044] The beam identifier corresponding to the first echo signal is at least one beam identifier of the first reference signal, and the at least one beam identifier of the first reference signal can determine a beam direction in which the first reference signal is sent, or in other words, can determine a reference signal of which the first echo signal is sent by using which beam, or in other words, can determine a geographical area in which the target appears.

[0045] Based on the technical solution, the third logic unit can determine the direction in which the target appears by receiving the first information sent by the first logic unit and used for indicating the first mode corresponding to the first echo signal and / or indicating the beam identifier corresponding to the first echo signal, and then can indicate the second mode to the first logic unit based on the determined direction in which the target appears, so that the first logic unit can send the reference signal based on the second mode to perceive the target. It can be seen that the method provided in the present application can dynamically adjust the sending mode of the reference signal according to the received echo, and realizes flexible adjustment of the sending manner of the reference signal used for perception, and effectively improves the perception accuracy of the target.

[0053] The plurality of beamforming precodings of the first reference signal can be replaced by: a plurality of beamforming precodings used for transmitting the first reference signal.

[0054] The plurality of beam weight values of the first reference signal can be replaced by: a plurality of beam weight values used for transmitting the first reference signal.

[0055] With reference to the first aspect and the second aspect, in some implementations of the first aspect and the second aspect, in a case where the third information indicates the plurality of beam identifications, the second information is further used for indicating a beam identification of the second reference signal, the beam identification of the second reference signal belonging to the plurality of beam identifications.

[0061] The first mode corresponding to the first echo signal is a mode of the first echo signal, and the first mode includes information used to indicate that a receiving mode of the first echo signal is a scanning mode.

[0062] The beam identifier corresponding to the first echo signal is a beam identifier of the first echo signal received by the second logic unit, and the beam identifier of the first echo signal is used to determine a beam direction for receiving the first echo signal, or in other words, is used to determine a geographical area where the target appears.

It can be seen that the method provided by the application can dynamically adjust the transmission mode of the reference signal according to the received echo, and flexibly adjust the transmission mode of the reference signal for perception, thereby effectively improving the perception accuracy.

[0103] The technical solutions in the present application will be described below with reference to the drawings.

[0104] For the convenience of understanding the embodiments of the present application, the following points are first explained.

[0105] First, in the embodiments of the present application, the use of prefixes such as "first", "second", etc. is merely for the convenience of distinguishing different things belonging to the same name category, and does not constrain the order, size or quantity of the things. For example, "first logical unit" and "second logical unit" are merely different logical units, and do not limit the quantity or priority of the logical units; for example, "first information" and "second information" are merely different information, and do not have a size relationship or priority relationship; for example, "first reference signal" and "second reference signal" are merely reference signals sent in different modes, and do not limit the number of times or priority of sending the reference signals.

[0106] Second, in the present application, information may be processed as necessary before being sent from the source end to the destination end, such as encoding, modulation, etc., and the destination end may also perform corresponding processing after receiving the information from the source end, such as decoding, demodulation, etc., to interpret the valid information from the source end. Wherein, the source end refers to the sending end, and the destination end refers to the receiving end.

[0107] Third, in the embodiments of the present application, "at least one" means one or more, and "multiple" means two or more. "And / or" describes the association between the associated objects, indicating that there can be three relationships, for example, A and / or B, which can represent the following situations: A exists alone, A and B exist together, and B exists alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after it, but does not exclude the case where the associated objects before and after it represent an "and" relationship, and the meaning expressed can be understood in conjunction with the context. "At least one of the following" or similar expressions means any combination of these items, including any combination of single or multiple items. For example, at least one of a, b, or c, can represent: a, b, c; a and b; a and c; b and c; or a and b and c. Where a, b, c can be single or multiple.

[0108] Fourth, in the embodiments of the present application, "indicate" can include direct indication and indirect indication, and can also include explicit indication and implicit indication. The information indicated by certain information (the first information described below) is referred to as to-be-indicated information. In the implementation process, there are many ways to indicate the to-be-indicated information, for example, but not limited to, the to-be-indicated information can be directly indicated, such as the to-be-indicated information itself or an index of the to-be-indicated information. The to-be-indicated information can also be indirectly indicated by indicating other information, where the other information and the to-be-indicated information have an association relationship. The to-be-indicated information can also be indicated only by a part of the to-be-indicated information, and the other part of the to-be-indicated information is known or agreed in advance. For example, the indication of a specific information can be achieved by means of the arrangement order of each information agreed in advance (for example, protocol predefined), thereby reducing the indication overhead to a certain extent. The specific manner of indication is not limited in the present application.

[0109] It can be understood that, for the sender of the indication information, the indication information can be used to indicate the to-be-indicated information, and for the receiver of the indication information, the indication information can be used to determine the to-be-indicated information.

[0110] Fifth, the tables in the embodiments of the present application are only examples. The values of the information in the tables are only examples, and can be configured as other values. The present application is not limited. The tables do not limit the protection scope of the present application. For example, the above tables can be appropriately deformed and adjusted, for example, split, merged, and the like. For another example, the parameter names shown in the titles of the tables can also use other names understandable by the communication device, and the values or representation methods of the parameters can also use other values or representation methods understandable by the communication device. For another example, the above tables can also use other data structures when implemented, for example, an array, a queue, a container, a stack, a linear table, a pointer, a linked list, a tree, a graph, a structure, a class, a heap, a hash table, or the like.

[0111] Sixth, in the embodiments of the present application, "when", "in the case of", "if", and the like all refer to that the device (such as the first communication device or the second communication device) will make corresponding processing under certain objective circumstances, and are not limited to time, and do not require the device (such as the first communication device or the second communication device) to have a judgment action when implemented, and also do not mean that there are other limitations.

[0112] Seventh, the predefinition in the present application can be understood as: definition, predefinition, storage, pre-storage, pre-negotiation, pre-configuration, solidification, or pre-burning.

[0113] The technical solutions provided in the present application can be applied to various communication systems, for example: a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD), a sidelink (SL) communication system, a worldwide interoperability for microwave access (WiMAX) communication system, a 5th generation (5G) mobile communication system or a new radio access technology (NR), a satellite communication system, and the like. The 5G mobile communication system can include non-standalone (NSA) and / or standalone (SA).

[0114] The technical solutions provided in the present application can also be applied to future communication systems, such as future communication networks.

[0115] With the development of wireless technology, an access network device not only has the function of communicating with a user, but also has the function of sensing the surrounding environment. Illustratively, the access network device can determine the situation of the surrounding environment by processing the transmitted reference signal for sensing and the echo information of the reference signal reflected by the object. That is, the access network device can determine whether there is an object around the base station through the sensing function. At present, in order to be able to sense the situation of the surrounding environment in time, the access network device needs to continuously and uninterruptedly transmit the sensing reference signal, so that the missing detection probability of the newly appeared object in the environment is low.

[0116] The access network device described above is a device with wireless transceiving function, for example, it can be a radio access network (RAN) device, which is used to provide wireless communication function service and can access terminal devices to the wireless network. The radio access network device can be a node in the radio access network, referred to as a RAN node.

[0117] In a possible scenario, the RAN node can be a base station (BS), an evolved NodeB (eNodeB), a transmission reception point (TRP), a home evolved NodeB, or a home Node B (HNB), a wireless fidelity (Wi-Fi) access point (AP), a mobile switching center, or a base station in a future mobile communication system, etc. The RAN node can also be a device assuming a base station function in a device to device (D2D) communication system, a vehicle to everything (V2X) communication system, a machine to machine (M2M) communication system, and an internet to things (IoT) communication system, etc. The RAN node can also be a RAN node in a non terrestrial network (NTN), i.e., the RAN node can be deployed in a high altitude platform or a satellite. The RAN node can be a macro base station, or a micro base station or an indoor station, or a relay node or a donor node, etc., or a radio controller in a cloud radio access network (CRAN) scenario, a node in an open radio access network (O-RAN or ORAN) scenario, etc. Alternatively, the RAN node can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, the RAN node in a V2X technology can be a road side unit (RSU). Of course, the RAN node can also be a node in a core network.

[0118] In another possible scenario, multiple RAN nodes cooperate to realize the sensing function, and different RAN nodes respectively realize part of the functions of the base station. For example, the RAN node can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately arranged, or can also be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a radio frequency remote unit (RRU), an active antenna processing unit (AAU), or a remote radio head (RRH).

[0119] 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 an open CU (O-CU), the DU can also be referred to as an open DU (O-DU), the CU-CP can also be referred to as an open CU-CP (O-CU-CP), the CU-UP can also be referred to as an open CU-UP (O-CU-UP), and the RU can also be referred to as an open RU (O-RU).

[0120] Any of the CU (or CU-CP, CU-UP), DU and RU can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module. That is, the above-mentioned access network device can be a virtualized device, which is implemented by general hardware and instantiated virtualized functions, or special hardware and instantiated virtualized functions. The general hardware can be a server, such as a cloud server.

[0121] Exemplarily, one base station can logically divide one CU and one or more DUs, i.e., one CU and one or more DUs cooperatively work together to realize the function of the base station, as shown in FIG. 1. Wherein, each DU is connected with the CU through an F1 logical interface, and the DU is used to process the operation related to the radio link control (RLC) layer, the media access control (MAC) layer and the physical layer (PHY) layer, and the CU is used to process the operation related to the service data adaptation protocol (SDAP) layer, the radio resource control (RRC) layer and the packet data convergence protocol (PDCP) layer.

[0122] In combination with the foregoing description of the wireless access network device, it can be obtained that in some split architecture, one base station can be further divided into a CU, a DU and an RU, i.e., the CU, the DU and the RU cooperatively work together to realize the function of the base station, as shown in FIG. 2. Wherein, in the CU-DU-RU split architecture, the interface between the DU and the RU can be referred to as a front-haul interface, the interface between the CU and the DU can be referred to as a middle-haul interface, and the interface between the CU and the core network can be referred to as a backhaul interface.

[0123] Wherein, the RU is used to process part or all of the operation related to the PHY layer, and the DU is used to process the operation related to the RLC layer and the MAC layer, or part of the operation related to the PHY layer. That is, in the CU, DU and RU split architecture, the operation of the PHY is processed by the two units of the DU and the RU, or the operation of the PHY is completely processed by the RU.

[0124] Exemplarily, the RU can be used to perform at least one of the following PHY layer operations: scrambling, modulation, precoding, beamforming, or analog-to-digital conversion, etc.

[0125] In the present application, the logical unit (or communication unit, access network element) used to process the operation related to the RLC layer and the MAC layer is referred to as a third logical unit (for example, a DU), and the logical unit (or communication unit, access network element) used to process all or part of the operation related to the PHY layer is referred to as a first logical unit or a second logical unit (for example, an RU).

[0126] It should be noted that in the embodiments of the present application, the CU and the DU can be deployed according to the split architecture or the combined architecture, which is not limited in the present application.

[0127] In the CU-DU-RU separation architecture, when the reference signal for sensing is transmitted by the RU, the DU instructs the RU to transmit the reference signal through the front-haul interface. For example, the DU can send a reference signal transmission instruction to the RU, and the RU transmits the reference signal according to the reference signal transmission instruction after receiving the reference signal transmission instruction. The reference signal transmission instruction can include the content of the reference signal to be transmitted, the time domain position information of the reference signal to be transmitted, the frequency domain position of the reference signal to be transmitted, and the beam direction information of the reference signal to be transmitted.

[0128] FIG. 3 is a schematic diagram of a communication architecture suitable for the method provided in the embodiments of the present application. As shown in FIG. 3, region 1 is a geographical area covered by RU1, and region 2 is a geographical area covered by RU2. The DU is connected to RU1 and RU2 through the front-haul interface. The DU can send a reference signal transmission instruction to RU1 or RU2. After RU1 (or RU2) receives the reference signal transmission instruction from the DU, it can transmit the reference signal based on the reference signal transmission instruction.

[0129] It can be understood that, in the case that the reference signal is reflected by the target to generate a backwave signal, the backwave signal can be received by RU1 or RU2. That is, the backwave signal of the reference signal transmitted by one RU and reflected by the target can be received by the RU that transmits the reference signal or by another RU.

[0130] FIG. 4 is a schematic diagram of a self-transmitting and self-receiving communication scenario provided in the embodiments of the present application. As shown in FIG. 4, the DU sends a reference signal transmission instruction to RU1, RU1 receives the instruction and transmits the reference signal, and receives the backwave signal of the reference signal reflected by the target; when the target moves to the coverage area of RU2, the DU can continue to send a reference signal transmission instruction to RU2, RU2 receives the instruction and transmits the reference signal, and receives the backwave signal of the reference signal reflected by the target.

[0131] FIG. 5 is a schematic diagram of a self-transmitting and other-receiving communication scenario provided in the embodiments of the present application. As shown in FIG. 5, the DU sends a reference signal transmission instruction to RU1, RU1 receives the instruction and transmits the reference signal, and RU2 receives the backwave signal of the reference signal transmitted by RU1 and reflected by the target.

[0132] The target in the present application can be a person, an animal, or an object in the environment.

[0133] In combination with the above description, in order to be able to perceive the change of the environment around the access network device in time, so that the probability of missing a newly appeared object in the environment is low. Therefore, in the scenario of DU and RU separation, the DU needs to instruct the RU to periodically and continuously send reference signals to different directions to perceive the surrounding environment information. However, due to the fact that this way of continuously and periodically sending reference signals for perception is not flexible enough, it is difficult to accurately perceive the target.

[0134] Therefore, embodiments of the present application provide a communication method and related apparatus, in which the way of sending reference signals by the RU is adjusted through the received echo signal to realize the perception of the target. The method can flexibly adjust the sending way of the reference signals for perception, and can effectively improve the accuracy of perception.

[0135] The method provided by the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0136] FIG. 6 is a schematic flowchart of a communication method 600 provided by the embodiments of the present application. It should be understood that the method provided by the present application can be applied to the communication architecture shown in FIGS. 2 to 4, but the embodiments of the present application are not limited thereto. For example, when the method provided by the present application is applied to the communication architecture shown in FIGS. 2 to 4, the third logical unit in FIG. 6 can be the DU in FIGS. 2 to 4, and the first logical unit and the second logical unit can be the RUs in FIGS. 2 to 4. More specifically, when the method provided by the present application is applied to the system architecture shown in FIG. 3 or FIG. 4, the first logical unit of the present application can be the RU1 in FIG. 3 or FIG. 4, and the second logical unit can be the RU2 in FIG. 3 or FIG. 4.

[0137] In the flowchart shown in FIG. 6, the method is shown from the perspective of the interaction between the third logical unit and the first logical unit, but the present application does not limit the subject performing the method. For example, the third logical unit in FIG. 6 can be replaced by a chip, a chip system, or a processor supporting the third logical unit to implement the method, and can also be software capable of implementing all or part of the functions of the third logical unit. The first logical unit in FIG. 6 can be replaced by a chip, a chip system, or a processor supporting the first logical unit to implement the method, and can also be software capable of implementing all or part of the functions of the first logical unit.

[0138] As shown in FIG. 6, the method 600 can include S601 to S606. The steps in the method 600 are described in detail below.

[0139] S601, the first logical unit sends first information to the third logical unit, the first information being used to indicate a first mode corresponding to a first echo signal and / or to indicate a beam identifier corresponding to the first echo signal. Correspondingly, the third logical unit receives the first information from the first logical unit.

[0140] The first echo signal is a signal reflected by the target from the first reference signal sent by the first logic unit. The first reference signal is a signal sent by the first logic unit.

[0141] The first mode corresponding to the first echo signal is the mode of the first reference signal, and the mode of the first reference signal can include information indicating that the first logic unit sends the first reference signal in a scanning manner or in a single direction manner. In the present application, the first logic unit can send the first reference signal in a scanning manner, that is, the first mode includes information indicating that the sending manner of the first reference signal is a scanning manner. In the scanning manner, the first logic unit sends the first reference signal to different directions, so the scanning manner can also be called a multi-direction manner or other names, which are not limited in the present application.

[0142] The beam identifier corresponding to the first echo signal is at least one beam identifier of the first reference signal, and the at least one beam identifier of the first reference signal can determine the beam direction of sending the first reference signal, or in other words, can determine the reference signal of which the first echo signal is the echo, or in other words, can determine the geographic area where the target appears. In another possible implementation, the first reference signal includes a plurality of reference signals, and the identifier of each reference signal corresponds to a beam identifier. In this manner, the beam identifier corresponding to the first echo signal is the identifier of at least one reference signal included in the first reference signal.

[0143] For example, the first logic unit sends the first reference signal using beam 1, beam 2, and beam 3, the first echo signal is a signal reflected by the target from the reference signal sent using beam 1, and the first information indicates that the beam identifier corresponding to the first echo signal is the beam identifier of beam 1. In another example, the first logic unit sends reference signals with reference signal identifiers 1, 2, and 3. The reference signals with the above identifiers 1, 2, and 3 can be collectively referred to as the first reference signal, and the reference signals with different identifiers correspond to different beam directions. In this example, the first echo signal is a signal reflected by the target from the reference signal corresponding to the reference signal identifier 1, and the first information indicates that the beam identifier corresponding to the first echo signal is the reference signal identifier 1.

[0144] Optionally, the first logic unit can also send the first echo information to the third logic unit, and the first echo information can be information obtained by processing the first echo signal by the first logic unit, for example, converting the first echo signal from an analog signal to a digital bit stream to obtain the first echo information.

[0145] It should be understood that the first echo information and the above-mentioned first information can be sent simultaneously or separately.

[0146] S602, the third logic unit sends, in response to the first information, second information to the first logic unit, the second information being used to instruct the first logic unit to activate the second mode. Correspondingly, the first logic unit receives the second information from the third logic unit.

[0147] Wherein, the "activation" can also be replaced by "enable", "use", "start" and other terms used to describe the start of using the second mode.

[0148] Exemplarily, the second information can directly or indirectly indicate the second mode, for example, the second information includes the second mode, or the second information includes an identification of the second mode.

[0149] Optionally, the second mode can include information used to indicate a transmission mode of the second reference signal, and the transmission mode of the second reference signal can be a one-way mode. In other words, the second mode can include information used to indicate that the transmission mode of the second reference signal is a one-way mode. In the one-way mode, the first logic unit transmits the first reference signal in the same direction, so the one-way mode can also be called a fixed direction mode, a specific direction mode or other names, which are not limited by the present application.

[0150] It can be understood that the second mode and the above-mentioned first mode can be predefined or indicated by the third logic unit.

[0151] Optionally, the third logic unit sending, in response to the first information, the second information to the first logic unit can include: the third logic unit determining the second mode based on the first information; and sending the second information to the first logic unit, the second information being used to instruct the first logic unit to activate the second mode.

[0152] Optionally, in the case where the first logic unit receives the second information, the first logic unit can use the second mode to transmit the second reference signal. It can be understood that the beam direction of the second reference signal is the same as or similar to the beam direction indicated by the above-mentioned beam identification corresponding to the first echo signal.

[0153] In the embodiments of the present application, the third logic unit can determine the direction of the target appearance by receiving the first echo signal corresponding to the first mode and / or the beam identification corresponding to the first echo signal sent by the first logic unit, and then can instruct the first logic unit to use the second mode based on the determined direction of the target appearance, so that the first logic unit can transmit the reference signal based on the second mode to perceive the target. It can be seen that the method provided by the present application can dynamically adjust the transmission mode of the reference signal according to the received echo, and realizes the flexible adjustment of the transmission mode of the reference signal used for perception, and effectively improves the perception accuracy of the target.

[0154] Optionally, before S601, the method 600 further includes: S603, the third logic unit sends third information to the first logic unit, the third information being used to instruct the first logic unit to activate the first mode. Correspondingly, the first logic unit receives the third information from the third logic unit.

[0155] Optionally, in the case that the first logic unit receives the third information, the first logic unit can use the first mode to send the first reference signal.

[0156] It can be understood that, before the first logic unit receives the third information, no information for activating other modes is received, and then the first information in S601 can not indicate the first mode corresponding to the first echo signal.

[0157] For the description of the first mode, reference can be made to the foregoing description in S601, which will not be repeated here.

[0158] Based on this, the first logic unit uses a scanning mode to send the first reference signal, and after receiving the echo signal of the first reference signal reflected by the target, the first logic unit continues to use a unidirectional mode to send the second reference signal to perceive the same target. This way of adjusting the sending of the reference signal from the scanning mode to the unidirectional mode, i.e., the way of adjusting the sending of the reference signal from multiple directions to a single direction, can effectively reduce the cost of air interface resources and the power consumption of perception.

[0159] Optionally, the third information is further used to indicate the beam direction of the first reference.

[0160] Exemplarily, the beam direction of the first reference signal can be determined by one or more of a beam identifier, a precoding of beamforming, or a beam weight.

[0161] Therefore, the above-mentioned third information can be further used to indicate at least one of the following information: a plurality of beam identifiers of the first reference signal, a plurality of precodings of beamforming of the first reference signal, a plurality of beam weights of the first reference signal, or identifiers of a plurality of reference signals included in the first reference signal.

[0162] Among them, the plurality of beam identifiers of the first reference signal are used to identify a plurality of beams, and based on the plurality of beam identifiers, a plurality of beam directions can be determined. That is, based on the plurality of beam identifiers, it can be determined which directions of the geographical areas need to send the first reference signal.

[0163] Optionally, the beam identifier corresponding to the first echo signal belongs to the plurality of beam identifiers of the first reference signal.

[0164] The multiple beamformed precodings of the first reference signal can be replaced by: multiple beamformed precodings used for transmitting the first reference signal. It should be understood that each beamformed precoding can determine one beam, and the multiple beamformed precodings can determine multiple different beams. The multiple different beams correspond to the multiple beam identifications, or in other words, the multiple different beams one-to-one correspond to the beams indicated by the multiple beam identifications of the first reference signal.

[0165] Similarly, the multiple beam weights of the first reference signal can be replaced by: multiple beam weights used for transmitting the first reference signal. It should be understood that each beam weight can determine one beam, and the multiple beam weights can determine multiple different beams. The multiple different beams correspond to the multiple beam identifications, or in other words, the multiple different beams one-to-one correspond to the beams indicated by the multiple beam identifications of the first reference signal.

[0166] Optionally, the second information is further used for indicating a beam direction of the second reference signal.

[0167] Similar to the beam direction of the first reference signal, the beam direction of the second reference signal can be determined by one or more of a beam identification, a beamformed precoding, or a beam weight.

[0168] Therefore, the second information can be further used for indicating: a beam identification of the second reference signal, beamformed precoding information of the second reference signal, and / or beam weight information of the second reference signal.

[0169] It can be understood that since the second mode is determined based on the beam identification corresponding to the first echo signal, the beam identification of the second reference signal belongs to the multiple beam identifications of the first reference signal.

[0170] Similarly, the beamformed precoding of the second reference signal belongs to the multiple beamformed precodings of the first reference signal; and the beam weight of the second reference signal belongs to the multiple beam weights of the first reference signal.

[0171] It can be understood that the beam indicated by the beam identification of the second reference signal is the same as the beam determined using the beamformed precoding of the second reference signal; or the beam indicated by the beam identification of the second reference signal is the same as the beam determined using the beam weight of the second reference signal; or the beam determined using the beamformed precoding of the second reference signal is the same as the beam determined using the beam weight of the second reference signal.

[0172] Optionally, after S603, the method 600 further includes: S604, the third logic unit sends sixth information to the second logic unit, the sixth information being used to instruct the second logic unit to activate the fourth mode. Correspondingly, the second logic unit receives the sixth information from the third logic unit.

[0173] The fourth mode includes information used to indicate that the transmission mode of the third reference signal is a one-way mode.

[0174] Optionally, in the case that the second logic unit receives the sixth information, the second logic unit uses the fourth mode to send the third reference signal.

[0175] The beam direction of the third reference signal corresponds to the beam direction of the second reference signal; or, the third reference signal corresponds to the second reference signal; or, the geographical area indicated by the beam of the third reference signal is the same as or similar to the geographical area indicated by the beam of the second reference signal.

[0176] Since the third logic unit knows the geographical area covered by the first logic unit and the geographical area covered by the second logic unit, when the target moves from the geographical area covered by the first logic unit to the geographical area covered by the second logic unit, the second logic unit can determine the beam of the third logic unit to send the third reference signal according to the geographical area corresponding to the beam of the second reference signal sent by the first logic unit (for convenience of description, hereinafter referred to as the first geographical area), so that the geographical area corresponding to the beam sending the third reference signal is the same as or similar to the first geographical area.

[0177] FIG. 7 is a schematic diagram of beams corresponding to each other according to an embodiment of the present application. As shown in FIG. 7, the beam identifiers of the reference signals sent by RU1 are respectively: beam identifier 1, beam identifier 2, and beam identifier 3, and the three beam identifiers correspond to three different geographical areas respectively; the beam identifiers of the reference signals sent by RU2 are respectively: beam identifier 4, beam identifier 5, and beam identifier 6, and the three beam identifiers correspond to three different geographical areas respectively. The geographical area corresponding to the beam identifier 1 is similar to the geographical area corresponding to the beam identifier 4. Therefore, when determining that the target moves from the geographical area covered by RU1 to the geographical area covered by RU2, the DU can send the third mode to RU2, in which the information of the beam identifier 1 is included.

[0178] Optionally, before S604, the method 600 further includes: the third logic unit determines that the target moves into the coverage area of the second logic unit.

[0179] Exemplarily, the third logic unit can determine that the target moves into the coverage area of the second logic unit according to the sensing result of the target.

[0180] The perception result of the target can be obtained by the third logic unit based on a second echo signal and a second reference signal, and the second echo signal is a signal reflected by the target from the second reference signal.

[0181] For example, the third logic unit can determine that the target moves into the coverage area of the second logic unit according to a prediction result of an artificial intelligence (AI) model. Specifically, the third logic unit can input the perception result of the target into the AI model to obtain a geographic area where the target appears at the next moment.

[0182] Optionally, before S601, the method 600 further includes: S605, the third logic unit sends seventh information to the first logic unit, and the seventh information is used to configure a plurality of modes, and the plurality of modes include the first mode and the second mode. Correspondingly, the first logic unit receives the seventh information from the third logic unit.

[0183] Each of the plurality of modes includes at least one of the following information: an indication of a signal transmission mode, a number of signal transmissions, a sequence format of generated signals, a time domain position of signals, or a frequency domain resource of signals.

[0184] The time domain position of the signal includes: a transmission period of the signal, a starting time domain position of the signal, or a duration of the signal; or includes: a transmission period of the signal, a starting time domain position of the signal, or an ending position of the signal; or includes: a transmission period of the signal, an ending time domain position of the signal, or a duration of the signal.

[0185] For example, the starting time domain position of the signal refers to a starting position of the signal in each transmission period, the ending time domain position of the signal refers to an ending position of the signal in each transmission period, and the duration of the signal refers to a duration of the signal in each transmission period. Based on the starting position or the ending position of the signal and the duration of the signal, the time domain resource occupied by the signal in each transmission period can be determined; or based on the starting position and the ending position of the signal, the time domain resource occupied by the signal in each transmission period can be determined.

[0186] Optionally, the plurality of modes further comprises a fourth mode. Since the first mode, the second mode and the fourth mode belong to the plurality of modes, the first mode can further comprise at least one of the following information: the number of times of transmitting the first reference signal, the sequence format of generating the first reference signal, the time domain position of the first reference signal, or the frequency domain resource of the first reference signal; the second mode can further comprise at least one of the following information: the number of times of transmitting the second reference signal, the sequence format of generating the second reference signal, the time domain position of the second reference signal, or the frequency domain resource of the second reference signal; the fourth mode can further comprise at least one of the following information: the number of times of transmitting the third reference signal, the sequence format of generating the third reference signal, the time domain position of the third reference signal, or the frequency domain resource of the third reference signal.

[0187] The reference signal transmitted in the first mode is referred to as the first reference signal, the reference signal transmitted in the second mode is referred to as the second reference signal, and the reference signal transmitted in the fourth mode is referred to as the third reference signal.

[0188] Exemplarily, the plurality of modes can be configured in the manner shown in Table 1, and each row of Table 1 defines a mode.

[0189] Table 1

[0190] It should be understood that Table 1 is only an example and does not constitute a limitation on the plurality of modes. In actual applications, more modes can be included, or more configuration information can be included in each mode, for example, each mode further comprises the following information: beam identification, precoding matrix of beamforming, or weight value of beamforming.

[0191] The long format sequence shown in Table 1 is suitable for a scenario in which the geographical area to be perceived is large, and the short format sequence is suitable for a scenario in which the geographical area to be perceived is small.

[0192] Taking the mode with the mode identification of 0001 shown in Table 1 as an example, the meaning of the information included in each mode is introduced: the transmission period of the reference signal is 500 ms, indicating that the RU transmits the reference signal according to the period of 500 ms; the transmission mode of the beam: scanning mode, indicating that it is transmitted in different directions, or single direction mode, indicating that it is repeatedly transmitted in the same direction; the number of times of transmitting the reference signal is 4, indicating that the RU transmits the reference signal 4 times in a period; the time domain information of the reference signal, for example, can be SFN, slot number, symbol number in Table 1; the frequency domain information of the reference signal, for example, can be the position of RB.

[0193] Optionally, for the time domain information, a time duration of the sending signal can also be included, for example, how many symbols; for the frequency domain information, a frequency domain bandwidth can also be included, for example, the number of RBs.

[0194] Optionally, before S601, the method 600 further includes: the third logic unit sends seventh information to the second logic unit. Correspondingly, the second logic unit receives the seventh information from the third logic unit. The description of the seventh information can refer to the foregoing description, which will not be repeated here.

[0195] Optionally, the method 600 further includes: S606, the third logic unit sends eighth information to the first logic unit, the eighth information being used to instruct the first logic unit to deactivate the first mode and / or the second mode. Correspondingly, the first logic unit receives the eighth information from the third logic unit.

[0196] Illustratively, in the case that the eighth information is used to instruct the first logic unit to deactivate the first mode, the first logic unit stops sending the first reference signal based on the eighth information.

[0197] It can be understood that after the third logic unit receives the first information sent from the first logic unit, information used to instruct the first logic unit to deactivate the first mode can be sent. Based on this, the first logic unit can be caused not to continue to send the first reference signal using the first mode, effectively saving the cost of air interface resources.

[0198] Illustratively, in the case that the eighth information is used to instruct the first logic unit to deactivate the second mode, the first logic unit stops sending the second reference signal based on the eighth information.

[0199] It can be understood that after the third logic unit determines that the target moves to the coverage area of the second logic unit, information used to instruct the first logic unit to deactivate the second mode can be sent, so that the first logic unit can not continue to send the second reference signal using the second mode, effectively saving the cost of air interface resources.

[0200] Illustratively, in the case that the eighth information is used to instruct the first logic unit to deactivate the first mode and the second mode, the first logic unit stops sending the first reference signal and the second reference signal based on the eighth information.

[0201] It can be understood that after the third logic unit determines that the target moves to the coverage area of the second logic unit, information used to instruct the first logic unit to deactivate the first mode and the second mode can be sent, so that the first logic unit can not continue to send the second reference signal using the first mode and the second mode, effectively saving the cost of air interface resources.

[0202] Optionally, after S604, the method 600 further includes: the third logic unit sends information to the second logic unit, the information being used to instruct the first logic unit to deactivate the fourth mode. Correspondingly, the second logic unit receives the information and stops sending the third reference signal to save the overhead of air interface resources.

[0203] FIG. 8 is a schematic flowchart of a communication method 800 according to an embodiment of the present application. It should be understood that the method provided by the present application can be applied to the communication architecture shown in FIG. 2, FIG. 3 or FIG. 5, but the embodiments of the present application are not limited thereto. For example, when the method provided by the present application is applied to the communication architecture shown in FIG. 2, FIG. 3 or FIG. 5, the third logic unit in FIG. 8 can be the DU in FIG. 2, FIG. 3 or FIG. 5, and the first logic unit and the second logic unit can be the RUs in FIG. 2, FIG. 3 or FIG. 5. More specifically, when the method provided by the present application is applied to the system architecture shown in FIG. 3 or FIG. 5, the first logic unit in the present application can be the RU1 in FIG. 3 or FIG. 5, and the second logic unit can be the RU2 in FIG. 3 or FIG. 5.

[0204] In the flowchart shown in FIG. 8, the method is illustrated from the perspective of the interaction among the first logic unit, the second logic unit and the third logic unit, but the present application does not limit the execution subject of the method. For example, the second logic unit in FIG. 8 can be replaced by a chip, a chip system or a processor supporting the second logic unit to implement the method, or can be software capable of implementing all or part of the functions of the second logic unit. The description of the third logic unit and the first logic unit can refer to the related description in the method 600 above, and will not be repeated here.

[0205] As shown in FIG. 8, the method 800 can include S801 to S806. The steps in the method 800 will be described in detail below.

[0206] S801, the second logic unit sends first information to the third logic unit, the first information being used to indicate a first mode corresponding to a first echo signal and / or a beam identifier corresponding to the first echo signal. Correspondingly, the third logic unit receives the first information from the second logic unit.

[0207] The first echo signal is a signal reflected by a target from the first reference signal. The first mode corresponding to the first echo signal is the mode of the first echo signal, and the first mode includes information used to indicate that the receiving mode of the first echo signal is a scanning mode.

[0208] The beam identifier corresponding to the first echo signal is the identifier of the beam through which the second logical unit receives the first echo signal, and the identifier of the beam is used to determine the beam direction in which the first echo signal is received, or in other words, to determine the geographical area in which the target appears. In another possible implementation, the first echo signal includes a plurality of echo signals, and the identifier of each echo signal corresponds to a beam identifier. In this manner, the beam identifier corresponding to the first echo signal is the identifier of at least one echo signal included in the first echo signal.

[0209] Optionally, the first information is also used to indicate at least one beam identifier of a first reference signal corresponding to the first echo signal, and the first reference signal is a signal transmitted by the first logical unit. The description of the at least one beam identifier of the first reference signal can refer to the description in S601, and will not be described here again.

[0210] Since the logical unit that transmits the first reference signal and the logical unit that receives the first echo signal are different logical units, the second logical unit is difficult to directly obtain the beam identifier of the first reference signal corresponding to the first echo signal. However, the first logical unit transmits the first reference signal according to the indication of the third logical unit, so the second logical unit can report the following information to the third logical unit to enable the third logical unit to determine the beam identifier of the first reference signal corresponding to the first echo signal: time information of the second logical unit receiving the first echo signal, frequency domain information of the second logical unit receiving the first echo signal, reception code sequence information of the second logical unit receiving the first echo signal, and identifier of at least one echo signal included in the first echo signal.

[0211] S802, the third logical unit transmits second information to the first logical unit in response to the first information, and the second information is used to instruct the first logical unit to activate the second mode. Correspondingly, the first logical unit receives the second information from the third logical unit.

[0212] The process can refer to the description in S602 described above, and will not be described here again.

[0213] Optionally, in the case where the first logical unit receives the first information, the first logical unit can use the second mode to transmit a second reference signal.

[0214] S803, the third logical unit transmits fourth information to the second logical unit in response to the first information, and the fourth information is used to instruct the second logical unit to activate the third mode. Correspondingly, the second logical unit receives the fourth information from the third logical unit.

[0215] The third mode includes information indicating that the receiving mode of the second echo signal is a single-direction mode, and the second echo signal is a signal reflected by the target from a second reference signal.

[0216] Optionally, in a case where the second logic unit receives the fourth information, the second logic unit can receive the second echo signal using the third mode.

[0217] In the embodiments of the present application, the third logic unit can determine the direction of the target by receiving the first mode corresponding to the first echo signal and / or the beam identifier corresponding to the first echo signal sent by the second logic unit, and then can indicate the second mode to the first logic unit based on the determined direction of the target, so that the first logic unit can send the reference signal based on the second mode, and indicate the third mode to the second logic unit, so that the second logic unit can receive the echo signal using the third mode to perceive the target. It can be seen that the method provided by the present application can dynamically adjust the sending mode of the reference signal according to the received echo, and realizes flexible adjustment of the sending mode of the reference signal for perception, thereby effectively improving the perception accuracy.

[0218] Optionally, before S801, the method 800 further includes: S804, the third logic unit sends ninth information to the first logic unit, and the ninth information is used to indicate that the first logic unit activates the fifth mode. Correspondingly, the first logic unit receives the ninth information from the third logic unit.

[0219] The fifth mode can include information indicating that the sending mode of the first reference signal is a scanning mode.

[0220] Optionally, in a case where the first logic unit receives the ninth information, the first logic unit can send the first reference signal based on the fifth mode.

[0221] Optionally, the ninth information is also used to indicate the beam direction of the first reference.

[0222] For the description of the ninth information, refer to the description of the third information in the above method 600, which will not be repeated here.

[0223] Optionally, the second information is also used to indicate the beam direction of the second reference signal.

[0224] For the description of the second information, refer to the description of the second information in the above method 600, which will not be repeated here.

[0225] Optionally, before S801, the method 800 further includes: S805, the third logic unit sends fifth information to the second logic unit, the fifth information being used to instruct the second logic unit to activate the first mode. Correspondingly, the second logic unit receives the fifth information from the third logic unit.

[0226] Optionally, in the case that the second logic unit receives the third information, the second logic unit can receive the first echo signal based on the first mode.

[0227] It should be noted that the period of the first logic unit sending the first reference signal based on the fifth information (hereinafter referred to as the sending period for the convenience of description) is different from the period of the second logic unit receiving the first echo signal based on the first mode (hereinafter referred to as the receiving period for the convenience of description). Exemplarily, the sending period is less than the receiving period, for example, the receiving period is a positive integer times of the sending period; or, the sending period is greater than the receiving period, for example, the sending period is a positive integer times of the receiving period.

[0228] Fig. 9 is a schematic diagram of the relationship between the sending period and the receiving period according to an embodiment of the present application. RU1 sends the reference signal by scanning through four beam directions, and RU2 also needs to scan and receive through multiple different beam directions. As shown in Fig. 9, RU1 uses beams 1, 2, 3 and 4 to send in turn in 0-499 ms, the four beams corresponding to four different directions, and RU2 uses beam 1 to receive in 0-499 ms, the direction corresponding to the beam 1 being the same as or close to the direction of the beam 1 sent by RU1; RU1 uses beams 1, 2, 3 and 4 to send in turn in 500-999 ms, and RU2 uses beam 2 to receive in 500-999 ms; RU1 uses beams 1, 2, 3 and 4 to send in turn in 1000-1499 ms, and RU2 uses beam direction 3 to receive in 1000-1499 ms; RU1 uses beams 1, 2, 3 and 4 to send in turn in 1500-1999 ms, and RU2 uses beam direction 4 to receive in 1500-1999 ms.

[0229] As can be seen from Fig. 9, the receiving period of RU2 is 4 times of the sending period of RU1. Through the process shown in Fig. 9, the receiving beam direction of RU2 corresponding to the sending beam direction of RU1 can be more accurately determined. The description of the correspondence between the beam directions can refer to the related description in Fig. 7 above, which will not be described here again.

[0230] Optionally, the fifth information is further used to indicate the beam direction of the first echo.

[0231] Exemplarily, the beam direction of the first echo signal can be determined by one or more of a beam identifier, a precoding of beamforming, or a beam weight.

[0232] Therefore, the fifth information can also be used to indicate at least one of the following: the multiple beam identifications of the first echo signal, the multiple beamforming precodings of the first echo signal, the multiple beam weights of the first echo signal, or the identification of the multiple echo signals included in the first echo signal.

[0233] The multiple beam identifications of the first echo signal are used to identify multiple beams, and based on the multiple beam identifications, multiple beam directions can be determined. That is, based on the multiple beam identifications, it can be determined in which direction the first echo signal needs to be received to which geographical area.

[0234] Optionally, the beam identification corresponding to the first echo signal in the S801 belongs to the multiple beam identifications of the first echo signal.

[0235] The multiple beamforming precodings of the first echo signal can be replaced by: multiple beamforming precodings used for transmitting the first echo signal. It should be understood that each beamforming precoding can determine one beam, and the multiple beamforming precodings can determine multiple different beams. The multiple different beams correspond to the multiple beam identifications, or in other words, the multiple different beams one-to-one correspond to the beams indicated by the multiple beam identifications of the first echo signal.

[0236] Similarly, the multiple beam weights of the first echo signal can be replaced by: multiple beam weights used for transmitting the first echo signal. It should be understood that each beam weight can determine one beam, and the multiple beam weights can determine multiple different beams. The multiple different beams correspond to the multiple beam identifications, or in other words, the multiple different beams one-to-one correspond to the beams indicated by the multiple beam identifications of the first echo signal.

[0237] Optionally, the fourth information is also used to indicate the beam direction of the second echo signal.

[0238] Similar to the beam direction of the first echo signal, the beam direction of the second echo signal can be determined by one or more of the beam identification, the beamforming precoding, or the beam weight.

[0239] Therefore, the fourth information can also be used to indicate: the beam identification of the second echo signal, the beamforming precoding information of the second echo signal, and / or the beam weight information of the second echo signal.

[0240] It can be understood that since the third mode is determined based on the beam identification corresponding to the first echo signal, the beam identification of the second echo signal belongs to the multiple beam identifications of the first echo signal.

[0241] Similarly, the beamformed precoding of the second echo signal belongs to the multiple beamformed precodings of the first echo signal; the beam weight of the second echo signal belongs to the multiple beam weights of the first echo signal.

[0242] It can be understood that the beam indicated by the beam identifier of the second echo signal is the same beam as the beam determined using the beamformed precoding of the second echo signal; or the beam indicated by the beam identifier of the second echo signal is the same beam as the beam determined using the beam weight of the second echo signal; or the beam determined using the beamformed precoding of the second echo signal is the same beam as the beam determined using the beam weight of the second echo signal.

[0243] Optionally, the method 800 further includes: S806, the third logic unit sends seventh information to the second logic unit, and the seventh information is used to configure multiple modes. Correspondingly, the second logic unit receives the seventh information from the third logic unit.

[0244] The multiple modes can include a first mode, a second mode, a third mode and a fifth mode, and each of the multiple modes includes at least one of the following information: a number of times of sending a signal, a sequence format of generating a signal, a time domain position of a signal, or a frequency domain resource of a signal.

[0245] The time domain position of the signal includes a sending period of the signal, a starting time domain position of the signal, or a duration of the signal.

[0246] For the description of the multiple modes, reference can be made to the description of the multiple modes in S605 above, which will not be repeated here.

[0247] Since the first mode, the second mode, the third mode and the fifth mode belong to the multiple modes, the first mode can further include at least one of the following information: a number of times of sending the first echo signal, a sequence format of generating the first echo signal, a time domain position of the first echo signal, or a frequency domain resource of the first echo signal; the third mode can further include at least one of the following information: a number of times of sending the second echo signal, a sequence format of generating the second reference signal, a time domain position of the second echo signal, or a frequency domain resource of the second echo signal; the second mode can further include at least one of the following information: a number of times of sending the second reference signal, a sequence format of generating the second reference signal, a time domain position of the second reference signal, or a frequency domain resource of the second reference signal; and the fifth mode can further include at least one of the following information: a number of times of sending the first reference signal, a sequence format of generating the first reference signal, a time domain position of the first reference signal, or a frequency domain resource of the first reference signal.

[0248] The reference signal transmitted in the first mode is referred to as a first reference signal, the reference signal transmitted in the second mode is referred to as a second reference signal, and the reference signal transmitted in the fourth mode is referred to as a third reference signal.

[0249] Optionally, the method 800 further includes that the third logic unit sends seventh information to the first logic unit, the seventh information being used for configuring multiple modes. Correspondingly, the first logic unit receives the seventh information from the third logic unit. For the description of the seventh information, refer to the description in S605 above, which will not be repeated here.

[0250] Optionally, after S803, the method 800 further includes that the third logic unit sends sixth information to the logic unit #1, the sixth information being used for instructing the logic unit #1 to activate the fourth mode, and the fourth mode includes information used for indicating that the transmission mode of the third reference signal is a one-way mode. Correspondingly, the logic unit #1 receives the sixth information from the third logic unit.

[0251] The logic unit #1 can be the second logic unit, or a logic unit other than the first logic unit and the second logic unit, which can communicate with the third logic unit, for example, the logic unit #1 is RU3.

[0252] Optionally, in the case where the logic unit #1 receives the sixth information, the logic unit #1 transmits the third reference signal using the fourth mode.

[0253] The beam direction of the third reference signal corresponds to the beam direction of the second reference signal, or in other words, matches the beam direction of the second reference signal, or in other words, the geographical area indicated by the beam of the third reference signal is the same as or similar to the geographical area indicated by the beam of the second reference signal.

[0254] Optionally, the method 800 further includes that the third logic unit sends information used for instructing to deactivate the fifth mode and / or the second mode to the first logic unit.

[0255] For example, in the case where the second logic unit receives information used for instructing the second logic unit to deactivate the fifth mode, the second logic unit stops transmitting the first reference signal based on the information.

[0256] For example, in the case where the second logic unit receives information used for instructing the second logic unit to deactivate the second mode, the first logic unit stops transmitting the second reference signal based on the information.

[0257] For example, in the case where the second logic unit receives information used for instructing the second logic unit to deactivate the fifth mode and the second mode, the first logic unit stops transmitting the first signal and the second reference signal based on the information.

[0258] In this way, the fifth mode and / or the second mode is deactivated, which can effectively save the overhead of air interface resources.

[0259] Optionally, the method 800 further includes that the third logic unit sends information for indicating deactivation of the first mode and / or the third mode to the second logic unit.

[0260] For example, in the case that the second logic unit receives information for indicating that the second logic unit deactivates the first mode, the second logic unit stops receiving the first echo signal based on the information.

[0261] For example, in the case that the second logic unit receives information for indicating that the second logic unit deactivates the third mode, the first logic unit stops receiving the second echo signal based on the information.

[0262] For example, in the case that the second logic unit receives information for indicating that the second logic unit deactivates the first mode and the third mode, the first logic unit stops receiving the first echo signal and the second echo signal based on the information.

[0263] In this way, the first mode and / or the third mode is deactivated, which can effectively save the overhead of air interface resources.

[0264] It should be understood that the size of the serial number of the above processes does not mean the order of execution, and the execution order of the processes should be determined according to their functions and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
