[0066] The communication method, device and storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0067] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0068] The terms "first" and "second" and the like in the specification and drawings of this application are used to distinguish different objects, or to distinguish different processing of the same object, rather than to describe a specific order of objects.

[0069] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0070] It should be noted that, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0071] In the description of the present application, unless otherwise specified, “plurality” means two or more.

[0072] With the rapid development of communication networks, the number of devices introduced into current communication networks has also increased. For example, relay communication devices such as NCR / RIS have been introduced into communication networks. Although the introduction of more devices into communication networks can expand the coverage of useful signals, it will also change the coverage of interference signals. In other words, the above-mentioned introduced devices are likely to introduce additional interference, resulting in poor signal quality and thus affecting service performance.

[0073] In view of this, an embodiment of the present application provides a communication method, in which a target device receives a first indication information to obtain the correspondence between at least one frequency domain resource and at least one beam of a first link. Since different beams of the first link in the beam of at least one first link correspond to different frequency domain resources, and the first link is used for signal transmission between the target device and the network device corresponding to the first link, the target device can occupy different frequency domain resources to transmit the signals of the corresponding network devices through different first links. In other words, the signals of the network devices corresponding to the beams of different first links may not be transmitted on the same frequency domain resources, thereby avoiding the transmission of the signals of the network devices corresponding to the beams of different first links on the same frequency domain resources to cause co-frequency interference, thereby reducing the mutual interference between the signals.

[0074] The technical solution provided in the embodiments of the present application can be applied to various communication systems, for example, a new radio (NR) communication system using the fifth generation mobile communication technology (5G), a future evolution system, or a multi-communication fusion system.

[0075] For example, Figure 1 A schematic diagram of the structure of a communication system 10 provided in an embodiment of the present application is shown in FIG. The communication system 10 may include at least one control module 101 , at least one target device 102 , at least one terminal 103 , and at least one network device 104 .

[0076] Among them, Figure 1As shown, a communication system 10 includes a control module, a target device, three terminals (e.g., terminal 1, terminal 2, and terminal 3), and two network devices (e.g., network device 1 and network device 2) as an example: network device 1 and network device 2 can be any two adjacent network devices. The target device can be located within the coverage of network device 1 and network device 2, so that the target device can communicate with network device 1 and network device 2. Terminal 1, terminal 2, and terminal 3 can be located within the coverage of the target device, however, terminal 1 and terminal 2 can communicate with network device 1 through the target device, and terminal 3 can communicate with network device 2 through the target device. In addition, optionally, as Figure 1 As shown, the communication system 10 may include a control module, which may be communicatively connected to a target device and / or a network device.

[0077] It is understandable that the above Figure 1 The number of control modules 101, the number of target devices 102, the number of terminals 103, and the number of network devices 104 shown in the figure are merely exemplary descriptions, and the embodiments of the present application do not impose any limitation thereto.

[0078] In one possible implementation, the target device 102 is used to receive first indication information, where the first indication information is used to indicate a correspondence between at least one frequency domain resource and at least one beam of a first link; beams of different links in the beam of at least one first link correspond to different frequency domain resources, and the first link is used for signal transmission between the target device 102 and a network device 104 corresponding to the first link.

[0079] In one possible implementation, the control module 101 is used to send first indication information, where the first indication information is used to indicate the correspondence between at least one frequency domain resource and at least one beam of a first link; different beams of at least one first link correspond to different frequency domain resources, and the first link is used for signal transmission between a target device 102 and a network device 104 corresponding to the first link.

[0080] In one possible implementation, the target device 102 is used to receive third indication information, where the third indication information is used to indicate the correspondence between at least one frequency domain resource and at least one beam of a second link; beams of different links in the beam of at least one second link correspond to different frequency domain resources, and the second link is used for signal transmission between the target device 102 and the terminal 103 corresponding to the second link.

[0081] In one possible implementation, the control module 101 is used to send third indication information, where the third indication information is used to indicate the correspondence between at least one frequency domain resource and at least one beam of a second link; different beams of the at least one second link correspond to different frequency domain resources, and the second link is used for signal transmission between the target device 102 and the terminal 103 corresponding to the first link.

[0082] Optionally, the control module 101 is used as a functional entity to communicate and interact with the target device 102 and / or the network device 104. Specifically, the control module 101 can exchange resource information with the target device 102, wherein the resource information is used to indicate the transmission resources occupied by the target device 102 when forwarding the signal. The control module 101 can exchange control information with the network device 104, wherein the control information can be used to indicate the signal forwarding method of the target device 102.

[0083] In addition, in some possible implementations, the above-mentioned control module 101 can be an independently deployed device, or can be integrated into other devices, such as a target device, or a network device, or a terminal, or other independent physical entities. The embodiments of the present application do not impose any restrictions on this.

[0084] It should be noted that the communication connection recorded in the embodiments of the present application may be a wired connection or a wireless connection, and the embodiments of the present application do not impose any restrictions on this.

[0085] Optionally, the target device 102 is mainly used to forward signals. In combination with the above example, the target device 102 can complete the forwarding of downlink signals based on the downlink receiving beam of the first link and the downlink transmitting beam of the second link, and can complete the forwarding of uplink signals based on the uplink receiving beam of the second link and the uplink transmitting beam of the first link.

[0086] Exemplarily, the target device may include: NCR and / or RIS. Of course, the above is only an exemplary description of the target device, and the target device may also be other devices, and the present application embodiment does not impose any limitation on this.

[0087] Among them, NCR is a radio frequency repeater with the ability to send and receive information and process information. Specifically, NCR can optimize the amplification and forwarding strategy of the NCR signal based on the control information sent by the network device to achieve the purpose of adjusting the forwarding beam of the NCR signal, thereby effectively improving the signal amplification and forwarding efficiency.

[0088] As a two-dimensional electromagnetic metamaterial, RIS can actively and intelligently control electromagnetic waves in space in a programmable manner to form an electromagnetic field with controllable amplitude, phase, polarization, and frequency. As a carrier for intelligently controlling electromagnetic waves in space, the metasurface usually includes at least one series of periodically arranged electromagnetic unit structures. Among them, the electromagnetic unit structure integrates at least one adjustable element (for example, PIN diode, varactor diode, liquid crystal, microelectromechanical system (MEMS) switch, etc.) to obtain the reconfigurability of intelligently controlling electromagnetic waves in space.

[0089] It is understandable that deploying RIS in a wireless communication system can change the wireless communication environment from passive adaptation to active control, thereby building an intelligent wireless communication environment. In other words, the intelligent metasurface can intelligently and dynamically adjust the wireless communication environment, which can significantly improve the transmission performance between various communication devices in the wireless communication system, thereby enhancing the coverage performance of the wireless communication system.

[0090] In addition, deploying RIS in a wireless communication system can also assist network equipment in enhancing coverage, mainly by assisting network equipment in enhancing signal coverage at the cell edge and in blind spots. Specifically, the signal sent by the network equipment is mainly forwarded (for example, reflected or transmitted) to the terminal through RIS, and the signal sent by the terminal can also be forwarded to the network equipment through RIS. In addition, in order to expand the coverage and suppress interference, RIS needs to point the beam to a specific terminal through beamforming.

[0091] Optionally, the terminal 103 may be a large-capacity device with wireless communication function (for example, a server integrating a large number of boards), which may be deployed on land, including indoors or outdoors, handheld or vehicle-mounted. It may also be deployed on the water surface (such as a ship, etc.). It may also be deployed in the air (for example, on an airplane, a balloon, a satellite, etc.).

[0092] Optionally, the network device 104 may be a device with wireless transceiver function or a chip or chip system that can be set in the device. The network device 104 includes but is not limited to: a small base station, a wireless access point, a transceiver point (TRP), a transmission point (TP), a macro base station, a relay base station, and any other access node.

[0093] It should be noted that Figure 1 This is just an exemplary framework diagram. Figure 1 The number of nodes included in the Figure 1In addition to the functional nodes shown, the communication system 10 may also include other nodes, such as core network equipment, and this application does not impose any restrictions on this.

[0107] In the embodiment of the present application, the chip system may be composed of a chip, or may include a chip and other discrete devices.

[0108] In addition, the actions, terms, etc. involved in the various embodiments of the present application can refer to each other without limitation. The message name or parameter name in the message exchanged between the various devices in the embodiments of the present application is only an example, and other names can also be used in the specific implementation without limitation.

[0109] Combine the following Figure 1 The communication system shown describes the communication method provided in the embodiment of the present application. Among them, the actions, terms, etc. involved in the various embodiments of the present application can refer to each other without limitation. The message name or parameter name in the message exchanged between the various devices in the embodiment of the present application is only an example, and other names can also be used in the specific implementation without limitation. The actions involved in the various embodiments of the present application are only an example, and other names can also be used in the specific implementation, such as: "included in" in the embodiment of the present application can also be replaced by "carried on" or "carried in", etc.

[0110] In order to solve the problems existing in the above-mentioned prior art, the embodiment of the present application proposes a communication method that can reduce mutual interference between signals. Figure 3 As shown, the method includes:

[0111] S301: A control module sends first indication information. Correspondingly, a target device receives the first indication information.

[0112] The first indication information is used to indicate the correspondence between at least one frequency domain resource and at least one beam of a first link. Different beams of the at least one first link correspond to different frequency domain resources.

[0113] Optionally, different beams of the first link in the beams of at least one first link correspond to different frequency domain resources, which can be understood as different frequency domain resources in the at least one frequency domain resource are orthogonal in the frequency domain.

[0114] In a possible implementation, different beams of the first link in the above-mentioned at least one beam of the first link may correspond to different network devices. Exemplarily, the example in which at least one beam of the first link includes beam 1 of the first link and beam 2 of the first link is used for explanation: beam 1 of the first link may correspond to network device 1, and beam 2 of the first link may correspond to network device 2.

[0115] Further, in this implementation, combined with the aforementioned “different first link beams in at least one first link beam correspond to different frequency domain resources”, it can be understood that different network devices correspond to different frequency domain resources.

[0116] Exemplarily, at least one frequency domain resource includes frequency domain resource 1 and frequency domain resource 2, and at least one beam of the first link includes beam 1 of the first link and beam 2 of the first link. Frequency domain resource 1 may correspond to beam 1 of the first link, and frequency domain resource 2 may correspond to beam 2 of the first link. Beam 1 of the first link may correspond to network device 1, and beam 2 of the first link may correspond to network device 2. In other words, frequency domain resource 1 may correspond to network device 1, and frequency domain resource 2 may correspond to network device 2.

[0117] In another possible implementation, different beams of the first link in the beam of the at least one first link may correspond to the same network device. Exemplarily, the example in which the beam of the at least one first link includes beam 3 of the first link and beam 4 of the first link is used for explanation: beam 3 of the first link may correspond to network device 3, and beam 4 of the first link may correspond to network device 3.

[0118] Furthermore, in this implementation, combined with the aforementioned "different beams of the first link in the beam of at least one first link correspond to different frequency domain resources", it can be understood that the same network device can correspond to different frequency domain resources. In addition, optionally, different first links can be used to transmit different signals, and the frequency domain resources occupied by transmitting different signals can be different.

[0119] Exemplarily, at least one frequency domain resource includes frequency domain resource 1 and frequency domain resource 2, and at least one beam of the first link includes beam 3 of the first link and beam 4 of the first link. Frequency domain resource 1 may correspond to beam 3 of the first link, and frequency domain resource 2 may correspond to beam 4 of the first link. Beam 3 of the first link may correspond to network device 3, and beam 4 of the first link may correspond to network device 3. In other words, frequency domain resource 1 may correspond to network device 3, and frequency domain resource 2 may correspond to network device 3.

[0120] Optionally, the implementation process of the above S301 may be: the control module sends the first indication information to the target device. Correspondingly, the target device receives the first indication information from the control module. In other words, the control module may directly send the first indication information to the target device, so that the target device may directly obtain the first indication information from the control module.

[0121] Alternatively, the implementation process of the above S301 may be: the control module sends the first indication information to other relay devices. Accordingly, the other relay devices receive the first indication information from the control module. The other relay devices send the first indication information to the target device. Accordingly, the target device receives the first indication information from the other relay devices. In other words, the control module may send the first indication information to the target device through the other relay devices, so that the target device may indirectly obtain the first indication information from the control module through the other relay devices.

[0122] Of course, the above is only an exemplary description of the implementation process of S301. The above S301 can also be implemented in other ways, and the embodiments of the present application do not impose any limitation on this.

[0123] In the communication method provided by the present application, the target device receives the first indication information to learn the correspondence between at least one frequency domain resource and the beam of at least one first link. Since different beams of the first link in the beam of at least one first link correspond to different frequency domain resources, and the first link is used for signal transmission between the target device and the network device corresponding to the first link, the target device can occupy different frequency domain resources to transmit the signals of the corresponding network devices through different first links. In other words, the signals of the network devices corresponding to the beams of different first links may not be transmitted on the same frequency domain resources, thereby avoiding the transmission of the signals of the network devices corresponding to the beams of different first links on the same frequency domain resources to cause co-frequency interference, thereby reducing the mutual interference between the signals.

[0124] In addition, when different beams of at least one first link correspond to different network devices, the communication method provided in the embodiment of the present application supports multiple network devices to share the same target device, so that the target device can be used to forward signals of multiple network devices at the same time, thereby improving the transmission performance of multiple network devices.

[0125] As can be seen from the above description of "S301", the target device receives the first indication information to obtain the correspondence between at least one frequency domain resource and at least one beam of the first link, so that the target device can communicate with the network device corresponding to the beam of the at least one first link based on the first indication information. Figure 4 As shown, the communication method described in the embodiment of the present application may further include the following S401.

[0126] S401. A target device communicates with a network device corresponding to at least one beam of a first link on at least one frequency domain resource through a beam of a first link corresponding to at least one frequency domain resource.

[0127] Specifically, optionally, the first network device (i.e., any one of the network devices corresponding to the beam of at least one first link (hereinafter referred to as at least one network device)) is used as an example for explanation: the target device sends the uplink signal corresponding to the first network device to the first network device through the beam of the first link corresponding to the first frequency domain resource on the first frequency domain resource corresponding to the first network device; or, the target device receives the downlink signal sent by the first network device through the beam of the first link corresponding to the first frequency domain resource on the first frequency domain resource corresponding to the first network device. In a possible implementation, before the target device communicates with the network devices corresponding to the beam of at least one first link respectively through the beam of the first link corresponding to at least one frequency domain resource on at least one frequency domain resource (the above S401), the target device can determine the incident signals of different frequencies corresponding to different frequency domain resources based on the incident signal detection, and adjust the beam of the first link so that different beams of the first link are used to forward incident signals of different frequencies respectively. The information specifically included in the first indication information is described in detail below.

[0128] Optionally, the first indication information may specifically include an identifier of each frequency domain resource in at least one frequency domain resource, and / or an identifier of a beam of the first link corresponding to each frequency domain resource.

[0129] Specifically, optionally, the first indication information may include at least one forwarding resource (FwdRsrc), so that the first indication information may also be referred to as a forwarding resource set (FwdRsrcList). One forwarding resource corresponds to one frequency domain resource, and one forwarding resource corresponds to one beam of the first link. In other words, one forwarding resource may be used to characterize the correspondence between one frequency domain resource and one beam of the first link.

[0130] The forwarding resources may include an identifier of the frequency domain resource (FwdFreqRsrcId) and an identifier of the beam of the first link corresponding to the frequency domain resource (beamIndex).

[0131] For the identification of the frequency domain resource included in the above forwarding resource, exemplarily, the identification of the above frequency domain resource may include the identification of the frequency domain resource and / or the identification (subBandIndex) of each sub-bandwidth in at least one sub-bandwidth corresponding to the above frequency domain resource. Of course, the above is only an exemplary description of the identification of the above frequency domain resource, and the identification of the above frequency domain resource may also include other information, and the embodiments of the present application do not impose any limitation on this.

[0132] It is understandable that the beam of the first link is used for communication between the target device and the network device. That is, the beam of the first link can be an uplink transmission beam or a downlink reception beam used by the target device to transmit signals in the first link.

[0133] Exemplarily, at least one beam of the first link includes beam 1 of the first link and beam 2 of the first link as an example for explanation: beam 1 of the first link can be used for communication between the target device and the network device 1, that is, beam 1 of the first link can be used by the target device for transmitting an uplink transmission beam or a downlink reception beam of signal 1 in the first link. Beam 2 of the first link can be used for communication between the target device and the network device 2, that is, beam 2 of the first link can be used by the target device for transmitting an uplink transmission beam or a downlink reception beam of signal 2 in the first link.

[0134] For the identifier of the beam of the first link corresponding to the frequency domain resources included in the above-mentioned forwarding resources, optionally, the control module can directly indicate the identifier of the beam of the above-mentioned first link, for example, the control module directly indicates ***3.

[0135] Optionally, the control module can also indirectly indicate the identifier of the beam of the above-mentioned first link through the identifier of the beam of the link and the link indication information (LinkIndication). That is to say, the identifier of the beam of the first link includes the identifier of the beam of the link and the link indication information. Among them, the link indication information is used to indicate that the first indication information is used for signal transmission configured by the target device on the first link. For example, the beam identifier of the link is ***3, and the link indication information is true; and in the case where the link indication information is true, the link indication information can be used to indicate that the first indication information is used for signal transmission configured by the target device on the first link. In addition, optionally, in the case where the link indication information is true, the link indication information can be understood as the beam of the link is the beam of the first link.

[0136] Of course, the above description only takes the link indication information as an enumerated value type as an example. The above link indication information can also be an identifier of an integer value type, and the embodiment of the present application does not impose any limitation on this.

[0137] In an example, at least one frequency domain resource includes frequency domain resource 1, frequency domain resource 2, and frequency domain resource 3, and frequency domain resource 1 includes the 1st, 2nd, 4th to 6th PRBs (ie, PRB0, PRB1, PRB3, PRB4, and PRB5), frequency domain resource 2 includes the 14th to 23rd PRBs (ie, PRB15, PRB16, PRB17, PRB18, PRB19, PRB20, PRB21, PRB22, PRB23, and PRB24), and frequency domain resource 3 includes the 24th to 30th PRBs (ie, PRB25, PRB26, PRB27, PRB28, PRB29, PRB30, and PRB31) as an example for illustration:

[0138] When the beam identifier of the link corresponding to frequency domain resource 1 is the beam identifier 1 of the link, and the link indication information indicates that the first indication information is used for signal transmission configured for the target device on the first link (for example, the link indication information is true), the forwarding resource corresponding to frequency domain resource 1 can be expressed as: (frequency domain resource identifier = 1, frequency domain resource = {PRB0, PRB1, PRB3, PRB4, PRB5}, beam identifier = beam identifier 1, link indication = true).

[0139] When the beam identifier of the link corresponding to frequency domain resource 2 is the beam identifier 1 of the link, and the link indication information indicates that the first indication information is used for signal transmission configured for the target device on the first link (for example, the link indication information is true), the forwarding resource corresponding to frequency domain resource 2 can be expressed as: (frequency domain resource identifier = 2, frequency domain resource = {PRB15, PRB16, PRB17, PRB18, PRB19, PRB20, PRB21, PRB22, PRB23, PRB24}, beam identifier = beam identifier 1, link indication = true).

[0140] When the beam identifier of the link corresponding to frequency domain resource 3 is the beam identifier 2 of the link, and the link indication information indicates that the first indication information is used for signal transmission configured for the target device on the first link (for example, the link indication information is true), the forwarding resource corresponding to frequency domain resource 3 can be expressed as: (frequency domain resource identifier = 3, frequency domain resource = {PRB25, PRB26, PRB27, PRB28, PRB29, PRB30, PRB31}, beam identifier = beam identifier 2, link indication = true).

[0141] The following is a detailed description of the representation method of the first indication information.

[0142] As can be seen from the above introduction about the "control module", the above control module can be integrated into a terminal or a network device. In this case, the above first indication information can be carried in at least one of the following information: a radio resource control (RRC) message, a medium access control (MAC) control element (CE), or downlink control information (DCI). Of course, the above is only an exemplary description of the message carried by the first indication information. The above first indication information can also be carried in other messages. For example, when the above control module is integrated into the target device, the above first indication information can be carried in the internal interaction message of the target device. The embodiments of the present application do not impose any restrictions on this.

[0143] In view of this, the types of messages carried by the first indication information can be divided into the following three cases: Case 1 is that the first indication information is carried in an RRC message; Case 2 is that the first indication information is carried in a MAC CE; Case 3 is that the first indication information is carried in a DCI. Since the first indication information is represented differently in the above different cases, the representation of the first indication information in the above cases 1 to 3 is described in detail below.

[0144] Case 1 is that the first indication information is carried in the RRC message.

[0145] In the above situation 1, the above first indication information can be expressed in the following three ways: Mode 1 is that the first indication information includes the identifier of each frequency domain resource in at least one frequency domain resource, the identifier of the beam of the link corresponding to each frequency domain resource, and the link indication information corresponding to the beam of each link, and the above link indication information is information of enumerated numerical type. Mode 2 is that the first indication information includes the identifier of each frequency domain resource in at least one frequency domain resource, the identifier of the beam of the link corresponding to each frequency domain resource, and the link indication information corresponding to the beam of each link, and the above link indication information is information of integer numerical type. Mode 3 is that the first indication information includes the identifier of each frequency domain resource in at least one frequency domain resource, and the identifier of the beam of the first link corresponding to each frequency domain resource.

[0146] Method 1 is that the first indication information includes an identifier of each frequency domain resource in at least one frequency domain resource, an identifier of a beam of a link corresponding to each frequency domain resource, and link indication information corresponding to the beam of each link, and the above link indication information is information of an enumerated numerical type.

[0147] In mode 1, exemplarily, the above-mentioned link indication information may be true. In the case where the link indication information is true, the link indication information may indicate that the first indication information is used for signal transmission configured by the target device on the first link. In this case, the target device can obtain relevant information about the beam of the link corresponding to the frequency domain resource for transmitting signals between the target device and the network device through the first indication information, and adjust the beam of the first link corresponding to the frequency domain resource based on the above-mentioned first indication information, so that the subsequent target device can receive or send the uplink or downlink signal of the network device corresponding to the beam of the first link on the frequency domain resource through the beam of the first link corresponding to the frequency domain resource.

[0148] In addition, optionally, when the link indication information is false, the link indication information may indicate that the first indication information is used to configure signal transmission of the target device on other links, or the link indication information may indicate that the first indication information is not used to configure signal transmission of the target device on the first link.

[0149] Further, optionally, in the case where the link indication information is false, the link indication information can be understood as being used to indicate that the beam of the link is not the beam of the first link, or the link indication information can be understood as being used to indicate that the beam of the link is the beam of other links, for example, the beam of the above-mentioned other links is the beam of the link used to transmit signals between the target device and the terminal.

[0150] Exemplarily, the first indication information may be specifically as follows:

[0151]

[0152] Method 2 is that the first indication information includes an identifier of each frequency domain resource in at least one frequency domain resource, an identifier of a beam of a link corresponding to each frequency domain resource, and link indication information corresponding to the beam of each link, and the above link indication information is information of an integer value type.

[0153] In mode 1, exemplarily, the link indication information may be a first value Nr1. When the link indication information is the first value Nr1, the link indication information may indicate that the first indication information is used to configure the signal transmission of the target device on the first link. In this case, the target device may obtain relevant information about the beam of the link corresponding to the frequency domain resource for transmitting the signal between the target device and the network device through the first indication information, and adjust the beam of the first link corresponding to the frequency domain resource based on the first indication information, so that the subsequent target device can communicate with the network device corresponding to the beam of the first link on the frequency domain resource through the beam of the first link corresponding to the frequency domain resource.

[0154] In addition, optionally, when the link indication information is the second value Nr2, the link indication information may indicate that the first indication information is used to configure the signal transmission of the target device on other links, or the link indication information may indicate that the first indication information is not used to configure the signal transmission of the target device on the first link, for example, the beam of the above-mentioned other links is the beam of the link used to transmit signals between the target device and the terminal.

[0155] Exemplarily, the first indication information may be specifically as follows:

[0156]

[0157] Mode 3 is that the first indication information includes an identifier of each frequency domain resource in at least one frequency domain resource and an identifier of a beam of the first link corresponding to each frequency domain resource.

[0158] That is to say, in mode 3, the first indication information may not include link indication information, but the first indication information is used to configure the signal transmission of the target device on the first link by default. In this case, the target device can obtain the relevant information of the beam of the link corresponding to the frequency domain resource for transmitting the signal between the target device and the network device through the first indication information, and adjust the beam of the first link corresponding to the frequency domain resource based on the above first indication information, so that the subsequent target device can communicate with the network device corresponding to the beam of the first link on the frequency domain resource through the beam of the first link corresponding to the frequency domain resource.

[0159] Exemplarily, the first indication information may be specifically as follows:

[0160]

[0161] Case 2 is that the first indication information is carried in the MAC CE.

[0162] In the above situation 2, the first indication information may have the following two representation modes: Mode 4 is that the first indication information includes at least one of the following fields: a beamIndexi field, an L field, or an R field. Mode 5 is that the first indication information includes at least one of the following fields: a beamIndexi field, or an R field.

[0163] Mode 4 is that the first indication information includes at least one of the following fields: a beamIndex field, an L field, or an R field.

[0164] The beamIndex field is used to indicate the identifier of the beam of the link corresponding to each frequency domain resource in at least one frequency domain resource in the first indication information.

[0165] Optionally, one frequency domain resource may correspond to one beamIndex field. Exemplarily, at least one frequency domain resource includes frequency domain resource 1 and frequency domain resource 2 as an example: beamIndex0 may be used to indicate the identifier of the beam of the link corresponding to frequency domain resource 1. beamIndex1 may be used to indicate the identifier of the beam of the link corresponding to frequency domain resource 2. In this case, the number of beamIndex fields is the same as the number of frequency domain resources.

[0166] The L field is used to indicate whether the beam of the link is the beam of the first link.

[0167] Exemplarily, if the L field is a value a, the beam of the link is the first link, that is, the frequency domain resources corresponding to the beam of the link are used for transmitting and receiving signals on the beam of the first link. If the L field is b, the beam of the link is not the beam of the first link, for example, the beam of the link is the beam of another link, that is, the frequency domain resources corresponding to the beam of the link are used for transmitting and receiving signals on the beam of another link.

[0168] The R field is a reserved bit.

[0169] For example, Figure 5 As shown, the above-mentioned first indication information includes two forwarding resources (for example, forwarding resource 1 and forwarding resource 2) as an example: the beamIndex0 field identifies the beam of the link corresponding to the frequency domain resource 1 of forwarding resource 1, the beamIndex1 field identifies the beam of the link corresponding to the frequency domain resource 2 of forwarding resource 2, the L field is used to indicate whether the beam of the link is the beam of the first link, and the R field is a reserved field.

[0170] As another possible implementation manner, manner 4 may also be that the first indication information includes at least one of the following fields: a beamIndex field, an L field, an F field, or an R field.

[0171] The F field is used to indicate that at least one beamIndex included in the first indication information corresponds to at least one frequency domain resource.

[0172] Exemplarily, if the value of the above-mentioned F field is c, it indicates that at least one beamIndex in the first indication information corresponds to at least one frequency domain resource; if the value of the above-mentioned F field is d, it indicates that at least one beamIndex in the first indication information corresponds to at least one other resource other than the frequency domain resource, such as time resources or power resources.

[0173] That is to say, in mode 4, the first indication information may include the F field or may not include the F field, and the embodiment of the present application does not impose any limitation on this.

[0174] Mode 5 is that the first indication information includes at least one of the following fields: a beamIndex field or an R field.

[0175] In this mode 5, different types of MAC CE messages may be configured with different MAC headers (MAC subheaders), so that different types of MAC CE messages may be distinguished by different MAC headers.

[0176] Optionally, the MAC header can be distinguished by setting different values. Exemplarily, when the MAC header is a value x, it indicates that the MAC CE is used to configure the beam of the first link. When the MAC header is a value y, it indicates that the MAC CE is not used to configure the beam of the first link, that is, the MAC CE is used to configure the beam of other links. For example, the beam of the other link is a beam of a link used to transmit a signal between the target device and the terminal.

[0177] For example, Figure 6 As shown, taking the first indication information including two forwarding resources (for example, forwarding resource 1 and forwarding resource 2) as an example: the beamIndex0 field identifies the beam of the link corresponding to the frequency domain resource 1 of forwarding resource 1, the beamIndex1 field identifies the beam of the link corresponding to the frequency domain resource 2 of forwarding resource 2, and the R field is a reserved field.

[0178] Optionally, the embodiments of the present application do not impose any restrictions on the types of the above numerical values ​​and the size relationship between different numerical values.

[0179] It can be understood that the beamIndex field and the R field can be understood by referring to the description of the corresponding positions above, which will not be repeated here.

[0180] As another possible implementation manner, manner 5 may also be that the first indication information includes at least one of the following fields: a beamIndex field, an F field, or an R field.

[0181] That is to say, in method 5, the first indication information may include the F field or may not include the F field, and the embodiment of the present application does not impose any limitation on this.

[0182] Case 3: The first indication information is carried in the DCI

[0183] In the above situation 3, the first indication information includes at least one of the following fields: a beamIndex field, a subBandIndex field, or a LinkIndication field. Among them, the beamIndex field is used to identify the beam of the link corresponding to one frequency domain resource in at least one frequency domain resource; the subBandIndex field is used to identify one frequency domain resource in at least one frequency domain resource; there is a one-to-one correspondence between the beam of the link identified by the beamIndex field and the frequency domain resource identified by the subBandIndex; the LinkIndication field is used to indicate whether the beam of the link identified by the beamIndex field is the beam of the first link. In addition, if the RRC layer parameters include link indication information, the LinkIndication field is included in the DCI; otherwise, the LinkIndication field is not included in the DCI.

[0184] Exemplarily, the first indication information may be as follows:

[0185] -beamIndex0,beamIndex1,…,beamIndex N-1

[0186] -subBandIndex0,subBandIndex1,…,subBandIndexN-1

[0187] -LinkIndication

[0188] Among them, beamIndex0 and subBandIndex0 may correspond to a frequency domain resource with the smallest frequency domain resource identifier (for example, 0) in at least one frequency domain resource.

[0189] As can be seen from the above description of "S301", the control module sends the first indication information. However, before the control module sends the first indication information, the control module also needs to predetermine the first indication information so as to provide data preparation for the subsequent sending of the first indication information. Figure 7 As shown, the communication method described in the embodiment of the present application may further include the following S701 to S704.

[0190] S701. A control module obtains transmission requirement information of each network device in at least one network device.

[0191] Specifically, each network device in the at least one network device may send transmission requirement information to the control module. Correspondingly, the control module may receive the transmission requirement information of each network device.

[0192] The transmission requirement information may be used to indicate the transmission requirement of the network device. Exemplarily, the transmission requirement information may include at least one of the following: an identifier of the network device, a minimum transmission rate, or a maximum transmission rate.

[0193] Exemplarily, the at least one network device includes network device 1 and network device 2, and network device 1 and network device 2 simultaneously initiate a data transmission request process as an example: network device 1 can send transmission requirement information 1 to the control module. Accordingly, the control module can receive transmission requirement information 1 from network device 1. Network device 2 can send transmission requirement information 2 to the control module. Accordingly, the control module can receive transmission requirement information 2 from network device 2.

[0194] S702: The control module determines the frequency domain resources of each network device according to the transmission requirement information of each network device.

[0195] It can be understood that the frequency domain resources of the network device can be understood as the frequency domain resources of the signal transmitted by the target device to the network device.

[0196] In some possible implementations, different network devices in the at least one network device have different frequency domain resources. In addition, optionally, different network devices in the at least one network device have different frequency domain resources, which can be understood as the frequency domain resources of different network devices in the at least one network device are orthogonal in the frequency domain.

[0197] Exemplarily, the at least one network device includes network device 1 and network device 2 as an example for explanation: the frequency domain resources of network device 1 may include sub-bandwidth 0 to sub-bandwidth 3, and the frequency domain resources of network device 2 may include sub-bandwidth 4 to sub-bandwidth 8. In view of this example, it can be seen that the frequency domain resources of network device 1 and the frequency domain resources of network device 2 are different.

[0198] It can be understood that the frequency domain resources of the network device can be understood as the frequency domain resources of the signal transmitted by the target device to the network device, and can also be understood as the frequency domain resources of the signal received by the network device, and can also be understood as the frequency domain resources of the signal sent by the network device. The embodiments of the present application do not impose any restrictions on this.

[0199] Optionally, the control module can indicate the frequency domain resources of the network device in the following two ways: Method 1 is that the control module directly indicates the frequency domain resources of the network device; Method 2 is that the control module indicates the index of the frequency domain resources, wherein the index of the frequency domain resources corresponds to the identification of the network device.

[0200] Mode 1 is that the control module directly instructs the frequency domain resources of the network device.

[0201] In this mode 1, the control module can directly indicate the frequency domain resources of the network device with the sub-bandwidth as the granularity, so that the control module can indicate the identifier of at least one sub-bandwidth of the network device 1. Of course, the above is only an exemplary description of the control module directly indicating the frequency domain resources of the network device. The control module can also directly indicate the frequency domain resources of the network device based on the frequency domain resources of other granularities, and the embodiment of the present application does not impose any limitation on this.

[0202] Mode 2 is that the control module indicates the index of the frequency domain resource.

[0203] There is a corresponding relationship between the index of the frequency domain resource and the identifier of the network device.

[0204] In this mode 2, the control module can determine the index of the frequency domain resource of the network device based on the correspondence between the identifier of the network device and the index of the frequency domain resource. The index of the frequency domain resource is used to indicate at least one frequency domain resource, so that the subsequent target device can determine at least one frequency domain resource of the network device through the index of the frequency domain resource of the network device.

[0205] Optionally, different frequency domain resource indices are used to indicate different frequency domain resources. For example, when the frequency domain resource index is index 1, at least one frequency domain resource indicated by the frequency domain resource index is the 1st, 2nd, 4th to 6th sub-bandwidths of the entire bandwidth (i.e., sub-bandwidth 0, sub-bandwidth 1, sub-bandwidth 3, sub-bandwidth 4, and sub-bandwidth 5); when the frequency domain resource index is index 2, at least one frequency domain resource indicated by the frequency domain resource index is the 3rd, 7th to 9th sub-bandwidths of the entire bandwidth (i.e., sub-bandwidth 2, sub-bandwidth 6, sub-bandwidth 7, and sub-bandwidth 8).

[0206] Exemplarily, a sub-bandwidth may include at least one physical resource block (PRB). Take a sub-bandwidth including a PRB as an example for explanation: when the index of the frequency domain resource is index 1, the at least one frequency domain resource indicated by the index of the frequency domain resource is the 1st, 2nd, 4th to 6th PRB of the entire bandwidth (i.e., PRB0, PRB1, PRB3, PRB4, and PRB5); when the index of the frequency domain resource is index 2, the at least one frequency domain resource indicated by the index of the frequency domain resource is the 3rd, 7th to 9th PRB of the entire bandwidth (i.e., PRB2, PRB6, PRB7, and PRB8).

[0207] Further, optionally, the identifiers of network devices corresponding to different frequency domain resource indexes are also different. For example, when the index of the frequency domain resource is index 1, the identifier of the network device corresponding to the index of the frequency domain resource is network device identifier 1; when the index of the frequency domain resource is index 2, the identifier of the network device corresponding to the index of the frequency domain resource is network device identifier 2.

[0208] That is to say, by limiting the indexes of different frequency domain resources to indicate different frequency domain resources, and the indexes of different frequency domain resources correspond to the identifiers of different network devices, the frequency domain resources of different network devices can be different.

[0209] In one possible implementation, the control module determines the frequency domain resources of each network device based on the transmission requirement information of each network device. The implementation process can be as follows: the control module determines the number of frequency domain resources corresponding to each network device based on the transmission requirement information of each network device, and based on the number of frequency domain resources corresponding to each network device, configures frequency domain resources for each network device from all frequency domain resources to determine the frequency domain resources of each network device.

[0210] Further, optionally, as can be seen from the aforementioned description of “transmission requirement information”, the above transmission requirement information may include a minimum transmission rate. Taking the transmission requirement information including the minimum transmission rate as an example, the above control module determines the number of frequency domain resources corresponding to the network device according to the transmission requirement information of the network device in detail: the control module can establish a correspondence curve between the minimum transmission rate and the number of frequency domain resources, and based on the correspondence curve between the above minimum transmission rate and the number of frequency domain resources, determine the number of frequency domain resources corresponding to the minimum transmission rate as the number of frequency domain resources of the corresponding network device. In addition, optionally, the correspondence curve between the above minimum transmission rate and the number of frequency domain resources can be a linear curve or a nonlinear curve, and the embodiments of the present application do not impose any restrictions on this.

[0211] Optionally, there may be a positive correlation between the minimum transmission rate and the number of frequency domain resources. That is, if the minimum transmission rate corresponding to the network device is higher, the number of frequency domain resources of the network device or terminal is larger, so that the corresponding frequency domain resources can be dynamically allocated on demand to meet the transmission performance requirements of the network device.

[0212] Exemplarily, the at least one network device includes network device 1, network device 2, and network device 3 as an example: assuming that the minimum transmission rate of network device 1 is 1 megabits per second (Mbps), the minimum transmission rate of network device 2 is 2Mbps, the minimum transmission rate of network device 3 is 1.5Mbps, and the number of frequency domain resources that can be allocated to at least one network device is 100, then the number of frequency domain resources corresponding to network device 1 can be 5, the number of frequency domain resources corresponding to network device 2 can be 10, and the number of frequency domain resources corresponding to network device 3 can be 7.

[0213] Furthermore, taking the frequency domain resources with PRB granularity as an example for explanation: the frequency domain resources of network device 1 may include the 1st, 2nd, 4th to 6th PRBs (i.e., PRB0, PRB1, PRB3, PRB4, and PRB5), the frequency domain resources of network device 2 may include the 14th to 23rd PRBs (i.e., PRB15, PRB16, PRB17, PRB18, PRB19, PRB20, PRB21, PRB22, PRB23, and PRB24), and the frequency domain resources of network device 3 may include the 24th to 30th PRBs (i.e., PRB25, PRB26, PRB27, PRB28, PRB29, PRB30, and PRB31).

[0214] In addition, in combination with the above example, the index of the frequency domain resources of network device 1 may be index 1, the index of the frequency domain resources of network device 2 may be index 2, and the index of the frequency domain resources of network device 3 may be index 3.

[0215] Optionally, the frequency domain resources recorded in the embodiment of the present application may be continuous frequency domain resources or discrete frequency domain resources, and the embodiment of the present application does not impose any limitation on this.

[0216] The communication method described in the embodiment of the present application determines the frequency domain resources used for signal transmission of each terminal according to the transmission requirement information of the terminal, and allocates more frequency domain resources to the terminal with a larger minimum transmission rate. In this way, frequency domain resources can be allocated according to the transmission requirements to meet the transmission performance requirements of each terminal.

[0217] S703. The control module determines an identifier of a beam of the first link corresponding to the corresponding frequency domain resource.

[0218] Optionally, the implementation process of S703 above may be: the control module may determine the network device corresponding to the frequency domain resource based on the correspondence between the frequency domain resource and the network device. The control module may determine the line of sight propagation direction between the network device and the target device as the target direction, and determine the identifier of the beam corresponding to the target direction as the identifier of the beam of the first link. In other words, the beam direction corresponding to the beam of the link is the direction in which the target device points to the network device.

[0219] The control module can determine the identifier of the beam of the first link corresponding to each frequency domain resource in the at least one frequency domain resource based on the method described above. However, the beams of different links in the beam of at least one first link correspond to different frequency domain resources. If the beams of different first links in the beam of at least one first link correspond to different network devices, then the beams of different first links in the beam of at least one first link point to different network devices.

[0220] Further, optionally, there is a one-to-one correspondence between the identifier of the link beam and the shaping codebook of the link beam. The correspondence between the identifier of the link beam and the shaping codebook of the link beam can be preset in the target device, so that the target device can determine the shaping codebook of the link beam according to the correspondence between the identifier of the link beam and the shaping codebook of the link beam and the identifier of the link beam, and adjust the beam direction of the link beam according to the shaping codebook of the link beam, so that the beam of the link points to the network device corresponding to the beam of the link.

[0221] In one example, at least one beam of the first link includes beam 1 of the first link and beam 2 of the first link, and at least one frequency domain resource includes frequency domain resource 1 and frequency domain resource 2. Beam 1 of the first link may correspond to frequency domain resource 1, and beam 2 of the first link may correspond to frequency domain resource 2. Beam 1 of the first link may correspond to network device 1, that is, beam 1 of the first link may point to network device 1. Beam 2 of the first link may correspond to network device 2, that is, beam 2 of the first link may point to network device 2.

[0222] Another example is taken as an example that at least one beam of the first link includes beam 1 of the first link and beam 2 of the first link, and at least one frequency domain resource includes frequency domain resource 1, frequency domain resource 2, and frequency domain resource: beam 1 of the first link can correspond to frequency domain resource 1 and frequency domain resource 2, and beam 2 of the first link can correspond to frequency domain resource 3. Beam 1 of the first link can correspond to network device 1, that is, beam 1 of the first link can point to network device 1. Beam 2 of the first link can correspond to network device 2, that is, beam 2 of the first link can point to network device 2.

[0223] As can be seen from the aforementioned description of “the implementation process of the control module determining the identifier of the beam of the first link corresponding to the corresponding frequency domain resource”, there is a one-to-one correspondence between the identifier of the beam of the link and the beam direction corresponding to the beam of the link. However, optionally, the correspondence between the identifier of the beam of the link and the beam direction corresponding to the beam of the link can be pre-configured by the control module, or can be obtained by the control module from other devices, for example, the control module can obtain it from a network device or a terminal. In this case, the network device or the terminal needs to predetermine the correspondence between the identifier of the beam of the link and the beam direction corresponding to the beam of the link.

[0224] The communication method recorded in the embodiment of the present application determines the identifier of the beam of the first link corresponding to the frequency domain resource based on the correspondence between the frequency domain resource and the network device, so that the beam of the first link points to the location of the network device; when different frequency domain resources correspond to different network devices, the beams of the first link corresponding to different frequency domain resources point to different network devices respectively, so that the signals of different network devices are isolated in the frequency domain, which can reduce interference between different signals.

[0225] S704. The control module establishes a correspondence between at least one frequency domain resource and at least one beam of the first link based on the identifier of each frequency domain resource in at least one frequency domain resource and / or the identifier of the beam of the first link corresponding to each frequency domain resource to determine the first indication information.

[0226] It can be understood that the correspondence between at least one frequency domain resource and at least one beam of the first link and / or the first indication information can be understood by referring to the description of the corresponding position above, and will not be repeated here.

[0227] As can be seen from the above description of "S401", the target device communicates with the network device corresponding to the beam of at least one first link on at least one frequency domain resource through the beam of the first link corresponding to at least one frequency domain resource. However, after the target device communicates with the network device corresponding to the beam of at least one first link, the target device does not need to continuously communicate with the network device corresponding to the beam of at least one first link to avoid redundant signaling overhead.

[0228] Further, specifically, the control module sends the second indication information, and correspondingly, the target device receives the second indication information.

[0229] The second indication information is used to instruct to stop communicating with the target network device. The target network device is a network device in the network devices corresponding to the beam of at least one first link.

[0230] Optionally, the target network device may be a network device at which the data transmission process ends among the network devices corresponding to the beam of at least one first link. That is, the control module may send the second indication information when determining that the data transmission process of the network device ends. Correspondingly, the target device receives the second indication information.

[0231] Further, optionally, the implementation process of transmitting the second indication information between the control module and the target device can be: the control module sends the second indication information to other relay devices. Accordingly, the other relay devices receive the second indication information from the control module. The other relay devices send the second indication information to the target device. Accordingly, the target device receives the second indication information from the other relay devices. In other words, the control module can send the second indication information to the target device through other relay devices, so that the target device can indirectly obtain the second indication information from the control module through other relay devices.

[0232] Of course, the above is only an exemplary description of the implementation process of transmitting the second indication information between the control module and the target device. The implementation process of transmitting the second indication information between the above control module and the target device can also be implemented in other ways, and the embodiments of the present application do not impose any restrictions on this.

[0233] It can be understood that the relevant description about the carrying mode of the second indication information and the like can be understood by referring to the relevant description about the first indication information mentioned above, and will not be repeated here.

[0234] Optionally, the second indication information may also carry an identifier of a frequency domain resource corresponding to the target network device and / or an identifier of a beam of the first link corresponding to the target network device.

[0235] Exemplarily, the target network devices include network device 1 and network device 2. The second indication information may carry the identifier of the frequency domain resource 1 corresponding to network device 1 and / or the identifier of the beam 1 of the first link corresponding to network device 1. The second indication information may also carry the identifier of the frequency domain resource 2 corresponding to network device 2 and / or the identifier of the beam 2 of the first link corresponding to network device 2.

[0236] It is understandable that after the data transmission process of the target network device is completed, a second indication information is sent to the target device to instruct to stop communicating with the target network device to release the frequency domain resources allocated to the target network device and improve the resource utilization of the target device.

[0237] In addition, after the second indication information is transmitted between the control module and the target device, the target device can update the correspondence between at least one frequency domain resource and at least one beam of the first link, and remove the identifier of the frequency domain resource corresponding to the target network device and / or the identifier of the beam of the first link corresponding to the target network device from the first indication information.

[0238] In combination with the above example, if the target network device is the above network device 2, the updated first indication information may only include information related to network device 1, for example, the target device deletes the forwarding resource corresponding to frequency domain resource 3, and the updated first indication information includes the forwarding resource corresponding to frequency domain resource 1 and the forwarding resource corresponding to frequency domain resource 2. Specifically as follows:

[0239] When the beam identifier of the link corresponding to frequency domain resource 1 is the beam identifier 1 of the link, and the link indication information indicates that the beam of the link is the beam of the first link (for example, the link indication information is true), the forwarding resource corresponding to frequency domain resource 1 can be expressed as: (frequency domain resource identifier = 1, frequency domain resource = {PRB0, PRB1, PRB3, PRB4, PRB5}, beam identifier = beam identifier 1, link indication = true).

[0240] When the beam identifier of the link corresponding to frequency domain resource 2 is the beam identifier 1 of the link, and the link indication information indicates that the beam of the link is the beam of the first link (for example, the link indication information is true), the forwarding resource corresponding to frequency domain resource 2 can be expressed as: (frequency domain resource identifier = 2, frequency domain resource = {PRB15, PRB16, PRB17, PRB18, PRB19, PRB20, PRB21, PRB22, PRB23, PRB24}, beam identifier = beam identifier 1, link indication = true).

[0241] The present application embodiment proposes another communication method that can reduce mutual interference between signals. Figure 8 As shown, the method includes:

[0242] S801: The control module sends third indication information. Correspondingly, the target device receives the third indication information.

[0243] Among them, the third indication information is used to indicate the correspondence between at least one frequency domain resource and at least one beam of the second link. Beams of different links in the beam of at least one second link correspond to different frequency domain resources, which can be understood as the frequency domain resources of different beams of the second link in the beam of at least one second link are orthogonal in the frequency domain.

[0244] Optionally, different frequency domain resources included in at least one frequency domain resource can be understood as different frequency domain resources in at least one frequency domain resource being orthogonal in the frequency domain.

[0245] In a possible implementation, different beams of the second link in the beam of the at least one second link may correspond to different terminals. Exemplarily, the example in which the beam of the at least one second link includes beam 1 of the second link and beam 2 of the second link is used for explanation: beam 1 of the second link may correspond to network device 1, and beam 2 of the second link may correspond to network device 2.

[0246] Further, in this implementation, combined with the aforementioned “different beams of the second link in the beam of at least one second link correspond to different frequency domain resources”, it can be understood that different terminals correspond to different frequency domain resources.

[0247] Exemplarily, at least one frequency domain resource includes frequency domain resource 1 and frequency domain resource 2, and at least one beam of the second link includes beam 1 of the second link and beam 2 of the second link. Frequency domain resource 1 may correspond to beam 1 of the second link, and frequency domain resource 2 may correspond to beam 2 of the second link. Beam 1 of the second link may correspond to network device 1, and beam 2 of the second link may correspond to network device 2. In other words, frequency domain resource 1 may correspond to network device 1, and frequency domain resource 2 may correspond to network device 2.

[0248] In another possible implementation, different beams of the second link in the beam of the at least one second link may correspond to the same terminal. Exemplarily, the example in which the beam of the at least one second link includes beam 3 of the second link and beam 4 of the second link is used for explanation: beam 3 of the second link may correspond to network device 3, and beam 4 of the second link may correspond to network device 3.

[0249] Further, in this implementation, combined with the aforementioned "different beams of the second link in the beam of at least one second link correspond to different frequency domain resources", it can be understood that the same terminal can correspond to different frequency domain resources. In addition, optionally, different second links can be used to transmit different signals, and the frequency domain resources occupied by transmitting different signals can be different.

[0250] Exemplarily, at least one frequency domain resource includes frequency domain resource 1 and frequency domain resource 2, and at least one beam of the second link includes beam 3 of the second link and beam 4 of the second link. Frequency domain resource 1 may correspond to beam 3 of the second link, and frequency domain resource 2 may correspond to beam 4 of the second link. Beam 3 of the second link may correspond to network device 3, and beam 4 of the second link may correspond to network device 3. In other words, frequency domain resource 1 may correspond to network device 3, and frequency domain resource 2 may correspond to network device 3.

[0251] It can be understood that the relevant descriptions about the implementation process of S801, the specific information included in the third indication information, the representation method of the third indication information, and the control module determining the implementation process of the third indication information can be understood by referring to the description of the corresponding positions above, and will not be repeated here.

[0252] In the communication method provided by the present application, the target device receives the third indication information to learn the correspondence between at least one frequency domain resource and the beam of at least one second link. Since different beams of the second link in the beam of at least one second link correspond to different frequency domain resources, and the second link is used for signal transmission between the target device and the terminal corresponding to the second link, the target device can occupy different frequency domain resources to transmit the corresponding terminal signal through different second links. In other words, the signals of the terminals corresponding to the beams of different second links may not be transmitted on the same frequency domain resources, thereby avoiding the transmission of the signals of the terminals corresponding to the beams of different second links on the same frequency domain resources to cause co-channel interference, thereby reducing mutual interference between signals.

[0253] In addition, when different beams of at least one second link correspond to different terminals, the communication method provided in the embodiment of the present application supports multiple terminals to share the same target device, so that the target device can be used to forward signals of multiple terminals at the same time, thereby improving the transmission performance of multiple terminals.

[0254] As can be seen from the above description of "S801", the target device receives the third indication information to obtain the corresponding relationship between at least one frequency domain resource and at least one beam of the second link, so that the target device can communicate with the terminal corresponding to the beam of the at least one second link based on the third indication information. Fig. 9 As shown, the communication method described in the embodiment of the present application may further include the following S901.

[0255] S901. A target device communicates with a terminal corresponding to at least one beam of a second link on at least one frequency domain resource through a beam of a second link corresponding to at least one frequency domain resource.

[0256] Specifically, optionally, the target device sends a downlink signal to a terminal corresponding to a beam of at least one second link or receives an uplink signal sent by the corresponding terminal on at least one frequency domain resource through a beam of the second link corresponding to at least one frequency domain resource.

[0257] It is understandable that the implementation process of S901 can also be understood by referring to the description of the corresponding position above, and will not be repeated here.

[0258] The information specifically included in the third indication information is described in detail below.

[0259] Optionally, the third indication information may specifically include an identifier of each frequency domain resource in at least one frequency domain resource, and / or an identifier of a beam of the second link corresponding to each frequency domain resource.

[0260] Specifically, optionally, the third indication information may include at least one forwarding resource (FwdRsrc), so that the third indication information may also be referred to as a forwarding resource set (FwdRsrcList). One forwarding resource corresponds to one frequency domain resource, and one forwarding resource corresponds to one beam of the second link. In other words, one forwarding resource may also be used to characterize the correspondence between one frequency domain resource and one beam of the second link.

[0261] The forwarding resources may further include an identifier of the frequency domain resource (FwdFreqRsrcId) and an identifier of the beam of the second link corresponding to the frequency domain resource (beamIndex).

[0262] For the identification of the frequency domain resource included in the above forwarding resource, exemplarily, the identification of the above frequency domain resource may include the identification of the frequency domain resource and / or the identification (subBandIndex) of each sub-bandwidth in at least one sub-bandwidth corresponding to the above frequency domain resource. Of course, the above is only an exemplary description of the identification of the above frequency domain resource, and the identification of the above frequency domain resource may also include other information, and the embodiments of the present application do not impose any limitation on this.

[0263] It can be understood that the beam of the second link is used for communication between the target device and the terminal. That is, the beam of the second link can be an uplink transmission beam or a downlink reception beam used by the target device to transmit signals in the second link.

[0264] Exemplarily, at least one beam of the second link includes beam 1 of the second link and beam 2 of the second link as an example for explanation: beam 1 of the second link can be used for communication between the target device and terminal 1, that is, beam 1 of the second link can be an uplink transmission beam or a downlink reception beam used by the target device to transmit signal 1 in the second link. Beam 2 of the second link can be used for communication between the target device and terminal 2, that is, beam 2 of the second link can be an uplink transmission beam or a downlink reception beam used by the target device to transmit signal 2 in the second link.

[0265] For the identifier of the beam of the second link corresponding to the frequency domain resources included in the above-mentioned forwarding resources, optionally, the control module can directly indicate the identifier of the beam of the above-mentioned second link, for example, the control module directly indicates ***4.

[0266] Optionally, the control module can also indirectly indicate the identifier of the beam of the second link through the identifier of the beam of the link and the link indication information (LinkIndication). That is, the identifier of the beam of the second link includes the identifier of the beam of the link and the link indication information. Among them, the link indication information is used to indicate that the third indication information is used for the signal transmission configured by the target device on the second link. For example, the beam identifier of the link is ***4, and the link indication information is true; and in the case where the link indication information is true, the link indication information can be used to indicate that the third indication information is used for the signal transmission configured by the target device on the second link. In addition, optionally, in the case where the link indication information is true, the link indication information can be understood as the beam of the link is the beam of the second link.

[0267] Of course, the above description only takes the link indication information as an enumerated value type as an example. The above link indication information can also be an identifier of an integer value type, and the embodiment of the present application does not impose any limitation on this.

[0268] In an example, at least one frequency domain resource includes frequency domain resource 1, frequency domain resource 2, and frequency domain resource 3, and frequency domain resource 1 includes the 1st, 2nd, 4th to 6th PRBs (ie, PRB0, PRB1, PRB3, PRB4, and PRB5), frequency domain resource 2 includes the 14th to 23rd PRBs (ie, PRB15, PRB16, PRB17, PRB18, PRB19, PRB20, PRB21, PRB22, PRB23, and PRB24), and frequency domain resource 3 includes the 24th to 30th PRBs (ie, PRB25, PRB26, PRB27, PRB28, PRB29, PRB30, and PRB31) as an example for illustration:

[0269] When the beam identifier of the link corresponding to frequency domain resource 1 is the beam identifier 1 of the link, and the link indication information indicates that the third indication information is used for signal transmission configured by the target device on the second link (for example, the link indication information is true), the forwarding resource corresponding to frequency domain resource 1 can be expressed as: (frequency domain resource identifier = 1, frequency domain resource = {PRB0, PRB1, PRB3, PRB4, PRB5}, beam identifier = beam identifier 1, link indication = true).

[0270] When the beam identifier of the link corresponding to frequency domain resource 2 is the beam identifier 1 of the link, and the link indication information indicates that the third indication information is used for signal transmission configured by the target device on the second link (for example, the link indication information is true), the forwarding resource corresponding to frequency domain resource 2 can be expressed as: (frequency domain resource identifier = 2, frequency domain resource = {PRB15, PRB16, PRB17, PRB18, PRB19, PRB20, PRB21, PRB22, PRB23, PRB24}, beam identifier = beam identifier 1, link indication = true).

[0271] When the beam identifier of the link corresponding to frequency domain resource 3 is the beam identifier 2 of the link, and the link indication information indicates that the third indication information is used for signal transmission configured by the target device on the second link (for example, the link indication information is true), the forwarding resource corresponding to frequency domain resource 3 can be expressed as: (frequency domain resource identifier = 3, frequency domain resource = {PRB25, PRB26, PRB27, PRB28, PRB29, PRB30, PRB31}, beam identifier = beam identifier 2, link indication = true).

[0272] The representation method of the third indication information is described in detail below.

[0273] As can be seen from the above introduction about the "control module", the above control module can be integrated into a terminal or a network device. In this case, the above third indication information can be carried in at least one of the following information: RRC message MACCE, or DCI. Of course, the above is only an exemplary description of the message carried by the third indication information. The above third indication information can also be carried in other messages. For example, when the above control module is integrated into the target device, the above third indication information can be carried in the internal interaction message of the target device. The embodiment of the present application does not impose any restrictions on this.

[0274] In view of this, the types of messages carried by the third indication information can be divided into the following three cases: Case 1 is that the third indication information is carried in the RRC message; Case 2 is that the third indication information is carried in the MAC CE; Case 3 is that the third indication information is carried in the DCI. Since the third indication information is represented differently in the above different cases, the representation of the third indication information in the above cases 1 to 3 is described in detail below.

[0275] Case 1 is that the third indication information is carried in the RRC message.

[0276] In the above situation 1, the above third indication information can be expressed in the following three ways: Mode 1 is that the third indication information includes the identifier of each frequency domain resource in at least one frequency domain resource, the identifier of the beam of the link corresponding to each frequency domain resource, and the link indication information corresponding to the beam of each link, and the above link indication information is information of enumerated numerical type. Mode 2 is that the third indication information includes the identifier of each frequency domain resource in at least one frequency domain resource, the identifier of the beam of the link corresponding to each frequency domain resource, and the link indication information corresponding to the beam of each link, and the above link indication information is information of integer numerical type. Mode 3 is that the third indication information includes the identifier of each frequency domain resource in at least one frequency domain resource, and the identifier of the beam of the second link corresponding to each frequency domain resource.

[0277] Method 1 is that the third indication information includes an identifier of each frequency domain resource in at least one frequency domain resource, an identifier of a beam of a link corresponding to each frequency domain resource, and link indication information corresponding to the beam of each link, and the above link indication information is information of an enumerated numerical type.

[0278] In mode 1, exemplarily, the link indication information may be true. In the case where the link indication information is true, the link indication information may indicate that the third indication information is used for the target device to configure the signal transmission on the second link. In this case, the target device may obtain the relevant information of the beam of the link corresponding to the frequency domain resource for transmitting the signal between the target device and the terminal through the third indication information, and adjust the beam of the second link corresponding to the frequency domain resource based on the third indication information, so that the subsequent target device can communicate with the terminal corresponding to the beam of the second link on the frequency domain resource through the beam of the second link corresponding to the frequency domain resource.

[0279] In addition, optionally, when the link indication information is false, the link indication information may indicate that the third indication information is used to configure signal transmission of the target device on other links, or the link indication information may indicate that the third indication information is not used to configure signal transmission of the target device on the second link.

[0280] Further, optionally, in the case where the link indication information is false, the link indication information can be understood as being used to indicate that the beam of the link is not the beam of the second link, or the link indication information can be understood as being used to indicate that the beam of the link is the beam of other links, for example, the beam of the above-mentioned other links is the beam of the link used to transmit signals between the target device and the network device (i.e., the beam of the first link).

[0281] Method 2 is that the third indication information includes an identifier of each frequency domain resource in at least one frequency domain resource, an identifier of the beam of the link corresponding to each frequency domain resource, and link indication information corresponding to the beam of each link, and the above link indication information is information of integer value type.

[0282] In mode 2, exemplarily, the link indication information may be the first value Nr1. In the case where the link indication information is the first value Nr1, the link indication information may indicate that the third indication information is used for the target device to configure the signal transmission on the second link. In this case, the target device may obtain the relevant information of the beam of the link corresponding to the frequency domain resource for transmitting the signal between the target device and the terminal through the third indication information, and adjust the beam of the second link corresponding to the frequency domain resource based on the third indication information, so that the subsequent target device can communicate with the terminal corresponding to the beam of the second link on the frequency domain resource through the beam of the second link corresponding to the frequency domain resource.

[0283] In addition, optionally, when the link indication information is the second value Nr2, the link indication information may be the third indication information used to configure the signal transmission of the target device on other links, or the link indication information may indicate that the third indication information is not used to configure the signal transmission of the target device on the second link, for example, the beam of the above-mentioned other links is the beam of the link used to transmit signals between the target device and the network device (i.e., the beam of the first link).

[0284] Mode 3 is that the third indication information includes an identifier of each frequency domain resource in at least one frequency domain resource and an identifier of the beam of the second link corresponding to each frequency domain resource.

[0285] That is to say, in mode 3, the third indication information may not include link indication information, but the third indication information is used by default for the target device to configure signal transmission on the second link. In this case, the target device can obtain relevant information about the beam of the link corresponding to the frequency domain resource for transmitting signals between the target device and the terminal through the third indication information, and adjust the beam of the second link corresponding to the frequency domain resource based on the third indication information, so that the subsequent target device can communicate with the terminal corresponding to the beam of the second link on the frequency domain resource through the beam of the second link corresponding to the frequency domain resource.

[0286] It can be understood that the example of the third indication information in situation 2 can be understood by referring to the example of the first indication information in situation 2, and will not be repeated here.

[0287] Case 2 is that the third indication information is carried in the MAC CE message.

[0288] In the above situation 2, the third indication information may have the following two representation modes: Mode 4 is that the third indication information includes at least one of the following fields: a beamIndexi field, an L field, or an R field. Mode 5 is that the third indication information includes at least one of the following fields: a beamIndexi field, or an R field.

[0289] Mode 4 is that the third indication information includes at least one of the following fields: beamIndexi field, L field, or R field.

[0290] As another possible implementation manner, manner 4 may also be that the first indication information includes at least one of the following fields: a beamIndexi field, an L field, an F field, or an R field.

[0291] That is to say, in mode 4, the first indication information may include the F field or may not include the F field, and the embodiment of the present application does not impose any limitation on this.

[0292] Mode 5 is that the third indication information includes at least one of the following fields: a beamIndexi field or an R field.

[0293] As another possible implementation manner, manner 5 may also be that the first indication information includes at least one of the following fields: a beamIndexi field, an F field, or an R field.

[0294] That is to say, in method 5, the first indication information may include the F field or may not include the F field, and the embodiment of the present application does not impose any limitation on this.

[0295] It can be understood that the relevant description of the third indication information under situation 2 can be understood by referring to the relevant description of the first indication information under situation 2, and will not be repeated here.

[0296] Case 3: The third indication information is carried in the DCI

[0297] In the above situation 3, the third indication information includes at least one of the following fields: a beamIndex field, a subBandIndex field, or a LinkIndication field. Among them, the beamIndex field is used to identify the beam of the link corresponding to one of the at least one frequency domain resources; the subBandIndex field is used to identify one of the at least one frequency domain resources; there is a one-to-one correspondence between the beam of the link identified by the beamIndex field and the frequency domain resource identified by the subBandIndex; the LinkIndication field is used to indicate whether the beam of the link identified by the beamIndex field is the beam of the second link. In addition, if the RRC layer parameters include link indication information, the LinkIndication field is included in the DCI; otherwise, the LinkIndication field is not included in the DCI.

[0298] It can be understood that the relevant description of the third indication information under situation 3 can be understood by referring to the relevant description of the first indication information under situation 3, and will not be repeated here.

[0299] As can be seen from the above description of "S801", the control module sends the third indication information. However, before the control module sends the third indication information, the control module also needs to predetermine the third indication information in order to provide data preparation for the subsequent sending of the third indication information. Fig.10 As shown, the communication method described in the embodiment of the present application may also include the following S1001 to S1004.

[0300] S1001. A control module obtains transmission requirement information of each network device in at least one network device.

[0301] Specifically, each network device in the at least one network device may send transmission requirement information to the control module. Correspondingly, the control module may receive the transmission requirement information of each network device.

[0302] The transmission requirement information may also be used to indicate the transmission requirement of each terminal in at least one terminal accessing the network device. In this case, exemplarily, the transmission requirement information may include at least one of the following: an identifier of the network device, an identifier of the terminal, a minimum transmission rate, or a maximum transmission rate. In addition, the terminal involved in the at least one terminal is a terminal that initiates a data transmission request process.

[0303] Exemplarily, the at least one network device includes network device 1 and network device 2, and target terminal a, target terminal b, and target terminal c simultaneously initiate data transmission request messages as an example: network device 1 can send transmission requirement information 1 to the control module. Accordingly, the control module can receive transmission requirement information 1 from network device 1. The transmission requirement 1 may include the identifier of network device 1, the identifier of terminal 1, the identifier of terminal 2, the minimum transmission rate corresponding to terminal 1, the minimum transmission rate corresponding to terminal 2, the maximum transmission rate corresponding to terminal 1, or the maximum transmission rate corresponding to terminal 2. Network device 2 can send transmission requirement information 2 to the control module. Accordingly, the control module can receive transmission requirement information 2 from network device 2. The transmission requirement 2 may include the identifier of network device 2, the identifier of terminal 3, the minimum transmission rate corresponding to terminal 3, or the maximum transmission rate corresponding to terminal 3.

[0304] S1002. The control module determines the frequency domain resources of each network device according to the transmission requirement information of each network device.

[0305] It can be understood that the frequency domain resources of the network device can be understood as the frequency domain resources of the signal transmitted by the target device to at least one terminal accessing the network device.

[0306] In some possible implementations, the frequency domain resources of different network devices in the at least one network device are different, and the frequency domain resources of different terminals accessing the same network device are also different. In addition, optionally, the frequency domain resources of different network devices in the at least one network device are different, which can be understood as the frequency domain resources of different network devices in the at least one network device are orthogonal in the frequency domain. The frequency domain resources of different terminals in the at least one terminal are different, which can also be understood as the frequency domain resources of different terminals in the at least one terminal are orthogonal in the frequency domain.

[0307] Exemplarily, the at least one network device includes network device 1 and network device 2, the at least one terminal accessing network device 1 includes terminal 1 and terminal 2, and the at least one terminal accessing network device 2 includes terminal 3. The frequency domain resources of terminal 1 may include sub-bandwidth 0 to sub-bandwidth 3, the frequency domain resources of terminal 2 may include sub-bandwidth 4 to sub-bandwidth 8, and the frequency domain resources of terminal 3 may include sub-bandwidth 9 to sub-bandwidth 12. In view of this example, it can be seen that the frequency domain resources of terminal 1, the frequency domain resources of terminal 2, and the frequency domain resources of terminal 3 are all different.

[0308] It can be understood that the frequency domain resources of the network device can be understood as the frequency domain resources of the signal transmitted by the target device to the terminal accessing the network device, and can also be understood as the frequency domain resources of the signal received by the terminal accessing the network device, and can also be understood as the frequency domain resources of the signal sent by the terminal accessing the network device. The embodiments of the present application do not impose any restrictions on this.

[0309] Optionally, the control module can indicate the frequency domain resources of the network device in the following two ways: Method 1 is that the control module directly indicates the frequency domain resources of the network device; Method 2 is that the control module indicates the index of the frequency domain resources, wherein the index of the frequency domain resources corresponds to the identification of the network device.

[0310] Mode 1 is that the control module directly instructs the frequency domain resources of the network device.

[0311] In this mode 1, the control module directly indicates the frequency domain resources of the network device, that is, the control module can directly indicate the frequency domain resources of the signal received by each terminal in at least one terminal connected to the network device. The control module can directly indicate the frequency domain resources of the signal received by the above-mentioned terminal with sub-bandwidth as the granularity, so that the control module can indicate the identifier of at least one sub-bandwidth of terminal 1. Of course, the above is only an exemplary description of the control module directly indicating the frequency domain resources of the network device. The control module can also directly indicate the frequency domain resources of the network device based on frequency domain resources of other granularities, and the embodiments of the present application do not impose any restrictions on this.

[0312] Mode 2 is that the control module indicates the index of the frequency domain resource.

[0313] There is a corresponding relationship between the index of the frequency domain resource and the identifier of the terminal accessing the network device.

[0314] In this mode 2, the control module can determine the index of the frequency domain resource of the terminal accessing the network device based on the correspondence between the terminal identifier and the index of the frequency domain resource. The index of the frequency domain resource is used to indicate at least one frequency domain resource, so that the subsequent target device can determine at least one frequency domain resource of the terminal accessing the network device through the index of the terminal accessing the network device.

[0315] It can be understood that the index of the frequency domain resources and the related description of the frequency domain resources can be understood by referring to the description of the corresponding position above, and will not be repeated here.

[0316] Optionally, the terminal identifiers corresponding to different frequency domain resource indexes are also different. For example, when the frequency domain resource index is index 1, the terminal identifier corresponding to the frequency domain resource index is terminal identifier 1; when the frequency domain resource index is index 2, the terminal identifier corresponding to the frequency domain resource index is terminal identifier 2.

[0317] That is to say, by limiting the indexes of different frequency domain resources to indicate different frequency domain resources, and the indexes of different frequency domain resources corresponding to the identifiers of different terminals, the frequency domain resources of different terminals can be different.

[0318] In one possible implementation, the control module determines the frequency domain resources of each network device based on the transmission requirement information of each network device. The implementation process can be as follows: the control module determines the number of frequency domain resources corresponding to each terminal based on the transmission requirement information of each terminal among at least one terminal connected to the above-mentioned at least one network device, and based on the number of frequency domain resources corresponding to each terminal, configures frequency domain resources for each terminal from all frequency domain resources to determine the frequency domain resources of each terminal.

[0319] Further, optionally, as can be seen from the aforementioned description of "transmission requirement information", the above transmission requirement information may include a minimum transmission rate. Taking the transmission requirement information including the minimum transmission rate as an example, the above control module determines the number of frequency domain resources corresponding to the terminal according to the transmission requirement information of the terminal in detail: the control module can establish a correspondence curve between the minimum transmission rate and the number of frequency domain resources, and based on the correspondence curve between the above minimum transmission rate and the number of frequency domain resources, determine the number of frequency domain resources corresponding to the minimum transmission rate as the number of frequency domain resources of the corresponding terminal. In addition, optionally, the correspondence curve between the above minimum transmission rate and the number of frequency domain resources can be a linear curve or a nonlinear curve, and the embodiments of the present application do not impose any restrictions on this.

[0320] Optionally, there may be a positive correlation between the minimum transmission rate and the number of frequency domain resources. That is, if the minimum transmission rate corresponding to the terminal is higher, the number of frequency domain resources of the terminal or the terminal is larger, so that the corresponding frequency domain resources can be dynamically allocated on demand to meet the transmission performance requirements of the terminal.

[0321] Exemplarily, the at least one terminal includes terminal 1, terminal 2, and terminal 3 as an example: assuming that the minimum transmission rate of terminal 1 is 1Mbps, the minimum transmission rate of terminal 2 is 2Mbps, the minimum transmission rate of terminal 3 is 1.5Mbps, and the number of frequency domain resources that can be allocated to at least one terminal is 100, then the number of frequency domain resources corresponding to terminal 1 can be 5, the number of frequency domain resources corresponding to terminal 2 can be 10, and the number of frequency domain resources corresponding to terminal 3 can be 7.

[0322] Furthermore, taking the frequency domain resources with PRB granularity as an example for explanation: the frequency domain resources of terminal 1 may include the 1st, 2nd, 4th to 6th PRBs (i.e., PRB0, PRB1, PRB3, PRB4, and PRB5), the frequency domain resources of terminal 2 may include the 14th to 23rd PRBs (i.e., PRB15, PRB16, PRB17, PRB18, PRB19, PRB20, PRB21, PRB22, PRB23, and PRB24), and the frequency domain resources of terminal 3 may include the 24th to 30th PRBs (i.e., PRB25, PRB26, PRB27, PRB28, PRB29, PRB30, and PRB31).

[0323] In addition, in combination with the above example, the index of the frequency domain resources of terminal 1 may be index 1, the index of the frequency domain resources of terminal 2 may be index 2, and the index of the frequency domain resources of terminal 3 may be index 3.

[0324] The communication method recorded in the embodiment of the present application determines the frequency domain resources used for signal transmission of each terminal according to the transmission requirement information of the terminal, and allocates more frequency domain resources to terminals with a larger minimum transmission rate. In this way, frequency domain resources can be allocated according to transmission requirements to meet the transmission performance requirements of each terminal.

[0325] S1003. The control module determines an identifier of a beam of the second link corresponding to the corresponding frequency domain resource.

[0326] Optionally, the implementation process of the above S1003 may be: the control module may determine the terminal corresponding to the frequency domain resource based on the correspondence between the frequency domain resource and the terminal. The control module may determine the line of sight propagation direction between the network device and the terminal as the target direction, and determine the identifier of the beam corresponding to the target direction as the identifier of the beam of the second link. In other words, the beam direction corresponding to the beam of the second link is the direction in which the target device points to the terminal.

[0327] The control module can determine the identifier of the beam of the second link corresponding to each frequency domain resource in the at least one frequency domain resource based on the method described above. However, the beams of different links in the beam of at least one second link correspond to different frequency domain resources. If the beams of different second links in the beam of at least one second link correspond to different terminals, the beams of different second links in the beam of at least one second link point to different terminals.

[0328] Further, optionally, there is a one-to-one correspondence between the identifier of the link beam and the shaping codebook of the link beam. The correspondence between the identifier of the link beam and the shaping codebook of the link beam can be preset in the target device, so that the target device can determine the shaping codebook of the link beam according to the correspondence between the identifier of the link beam and the shaping codebook of the link beam and the identifier of the link beam, and adjust the beam direction of the link beam according to the shaping codebook of the link beam, so that the beam of the link points to the terminal corresponding to the beam of the link.

[0329] In one example, at least one beam of the second link includes beam 1 of the second link and beam 2 of the second link, and at least one frequency domain resource includes frequency domain resource 1 and frequency domain resource 2. Beam 1 of the second link may correspond to frequency domain resource 1, and beam 2 of the second link may correspond to frequency domain resource 2. Beam 1 of the second link may correspond to terminal 1, that is, beam 1 of the second link may point to terminal 1. Beam 2 of the second link may correspond to terminal 2, that is, beam 2 of the second link may point to terminal 2.

[0330] Another example is taken as an example that at least one beam of the second link includes beam 1 of the second link and beam 2 of the second link, and at least one frequency domain resource includes frequency domain resource 1, frequency domain resource 2, and frequency domain resource: beam 1 of the second link can correspond to frequency domain resource 1 and frequency domain resource 2, and beam 2 of the second link can correspond to frequency domain resource 3. Beam 1 of the second link can correspond to terminal 1, that is, beam 1 of the second link can point to terminal 1. Beam 2 of the second link can correspond to terminal 2, that is, beam 2 of the second link can point to terminal 2.

[0331] As can be seen from the aforementioned description of “the implementation process of the control module determining the identifier of the beam of the second link corresponding to the corresponding frequency domain resource”, there is a one-to-one correspondence between the identifier of the beam of the link and the beam direction corresponding to the beam of the link. However, optionally, the correspondence between the identifier of the beam of the link and the beam direction corresponding to the beam of the link can be pre-configured by the control module, or can be obtained by the control module from other devices, for example, the control module can obtain it from the terminal or the terminal. In this case, the network device or the terminal needs to predetermine the correspondence between the identifier of the beam of the link and the beam direction corresponding to the beam of the link.

[0332] The communication method recorded in the embodiment of the present application determines the identifier of the beam of the second link corresponding to the frequency domain resource based on the correspondence between the frequency domain resource and the terminal, so that the beam of the second link points to the location of the terminal; when different frequency domain resources correspond to different terminals, the beams of the second link corresponding to different frequency domain resources point to different terminals respectively, so that the signals of different terminals are isolated in the frequency domain, and the interference between different signals can be reduced.

[0333] S1004. The control module establishes a correspondence between at least one frequency domain resource and at least one beam of the second link based on the identifier of each frequency domain resource in at least one frequency domain resource and / or the identifier of the beam of the second link corresponding to each frequency domain resource to determine the third indication information.

[0334] It can be understood that the correspondence between at least one frequency domain resource and at least one beam of the second link and / or the third indication information can be understood by referring to the description of the corresponding position above, and will not be repeated here.

[0335] As can be seen from the aforementioned description of "S802", the target device communicates with the terminal corresponding to the beam of at least one second link on at least one frequency domain resource through the beam of the second link corresponding to at least one frequency domain resource. However, after the target device communicates with the terminal corresponding to the beam of at least one second link, the target device does not need to continuously communicate with the terminal corresponding to the beam of at least one second link to avoid redundant signaling overhead. In view of this, the communication method described in the embodiment of the present application may also include the following steps: the control module sends a fourth indication information. Accordingly, the target terminal receives the fourth indication information.

[0336] The fourth indication information is used to indicate to stop communicating with the target terminal. The target terminal is a terminal among the terminals corresponding to the beam of at least one second link.

[0337] Optionally, the target terminal may be a terminal at which the data transmission process ends among the terminals corresponding to the beam of at least one second link. That is, the control module may send the fourth indication information when determining that the data transmission process of the terminal ends. Correspondingly, the terminal receives the fourth indication information.

[0338] It can be understood that the implementation process of the control module sending the fourth indication information, as well as the related descriptions of the fourth indication information, can be understood by referring to the descriptions of the corresponding positions above, and will not be repeated here.

[0339] It is understandable that the above communication method can be implemented by a communication device. In order to implement the above functions, the communication device includes a hardware structure and / or software module corresponding to each function.

For example, each functional module can be divided corresponding to each function, or two or more functions can be integrated into one processing module. The above integrated modules can be implemented in the form of hardware or in the form of software functional modules. It should be noted that the division of modules in the embodiments disclosed in the present application is schematic and is only a logical function division. There may be other division methods in actual implementation.
