[0002] In a relay communication system, it means adjusting the forwarding beam through a forwarding device (e.g., a Network Controlled Repeater (NCR) or a Reconfigurable Intelligent Surface (RIS) etc.) to change the direction of the signal transmitted between the transmitter (e.g., a terminal device) and the receiver (e.g., a base station) to enhance the signal power and assist the communication between the transmitter and the receiver. Currently, the signal transmitted between the terminal device and the base station can be forwarded through a forwarding device in the area where the base station is located to enhance the signal power.

[0003] However, the signals transmitted between the terminal device and the base station include uplink signals (i.e., signals sent by the terminal device to the base station) and downlink signals (i.e., signals sent by the base station to the terminal device).

[0043] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0044] In the description of this application, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "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. In addition, "at least one" and "plurality" refer to two or more. The words "first", "second", etc. do not limit the quantity and execution order, and the words "first", "second", etc. do not limit them to be different.

[0045] In order to improve network coverage performance, different types of network equipment such as macro base stations, micro base stations, and radio frequency repeaters are used in mobile communication network deployment to achieve wide and deep coverage of wireless networks. As mobile communication networks evolve toward enhanced fifth-generation mobile communication technology (5th generation mobile communication technology-Advanced, 5G-A) / sixth-generation mobile communication technology (6th generation mobile communication technology-Advanced, 6G), various new relay communication technologies (such as network-controlled NCR technology and RIS technology) are introduced to provide more diverse technical solutions for network deployment.

[0046] Specifically, based on the RF repeater, the 3rd Generation Partnership Project Release-18 (3GPP Rel-18) proposed the network-controlled NCR technology based on the Rel-18 protocol standard. Compared with the traditional RF repeater, NCR is a RF repeater capable of receiving and processing control information from the network side. NCR can be used as a forwarding device in the relay communication system. Based on the control information sent from the network side, it optimizes and controls its amplification and forwarding strategy and adjusts its forwarding beam (also called link beam), thereby effectively improving the signal amplification and forwarding efficiency.

[0047] As a two-dimensional implementation of electromagnetic metamaterials, RIS actively and intelligently regulates electromagnetic waves in space in a programmable manner to form an electromagnetic field with controllable amplitude, phase, polarization and frequency. As a carrier for implementing electromagnetic regulation, RIS is usually composed of a series of periodically arranged electromagnetic unit structures. Among them, the electromagnetic unit structure integrates some adjustable elements (such as P-type semiconductor-impurity-N-type semiconductor (Positive Intrinsic-Negative, PIN) diodes, varactor diodes, liquid crystals, micro-electro-mechanical systems (micro-electro-mechanical system, MEMS) switches, etc.) to obtain the reconfigurability of electromagnetic wave regulation. The introduction of RIS changes the wireless propagation environment from passive adaptation to active control, thereby constructing an intelligent wireless environment. By dynamically adjusting the wireless channel environment, RIS can significantly improve the transmission performance between communication devices and enhance the coverage performance of wireless communication systems. In the relay communication system, RIS can be used as a forwarding device to assist in enhancing the coverage capability of the base station, especially when covering the edge of the cell and the blind spot area, the signal sent by the base station is forwarded (reflected / transmitted) to the terminal device through RIS, and the signal sent by the terminal device can also be forwarded to the base station through RIS. In order to expand the coverage of the base station and suppress interference, RIS needs to use beamforming to direct the RIS forwarding beam to a specific terminal device.

[0048] In summary, currently, a forwarding device in the area where the base station is located can be used to control the forwarding beam based on beamforming and other technologies to point it to the terminal device or base station in the coverage area, so as to forward the signal transmitted between the terminal device and the base station, enhance the signal power, and assist the communication between the terminal device and the base station. However, the signal transmitted between the terminal device and the base station includes an uplink signal and a downlink signal. When the forwarding device is used to forward the uplink signal and the downlink signal between the terminal device and the base station at the same time, the efficiency of the forwarding device in forwarding the signal will be poor. In addition, before the forwarding device controls the forwarding beam, it is necessary to determine the optimal forwarding device to be accessed by the terminal device. In particular, when there are multiple forwarding devices, the terminal device may access different forwarding devices to obtain different communication performance. If the terminal device may access a forwarding device, the efficiency of the forwarding device in forwarding the signal will be poor, which will lead to low signal transmission performance.

[0049] To solve the above problems, the present application provides a signal forwarding control method, which determines the uplink forwarding device (i.e., the first forwarding device) and the downlink forwarding device (i.e., the second forwarding device) used for uplink and downlink signal transmission of the terminal device, respectively, according to the access parameters (such as location, performance parameters, etc.) and other information of the terminal device. By sending control messages (also referred to as indication information) to the uplink forwarding device and the downlink forwarding device, respectively, the corresponding forwarding devices are indicated to be used for forwarding the uplink signal and the downlink signal of the terminal device, respectively. Furthermore, the uplink forwarding device and the downlink forwarding device respectively adjust the receiving beam and the transmitting beam on the link according to the indication information to forward the uplink signal and the downlink signal of the terminal device. In this way, the optimal forwarding device can be selected and accessed for the terminal device, while improving the transmission performance of the uplink signal and the downlink signal.

[0050] A signal forwarding control method provided in an embodiment of the present application can be applicable to a signal forwarding control system. Figure 1 FIG. 1 shows a schematic diagram of the structure of a signal forwarding control system. Figure 1 As shown, the signal forwarding control system 10 includes: a terminal device 11, a base station 12, an uplink forwarding device 13 (i.e., the first forwarding device in this application), and a downlink forwarding device 14 (i.e., the second forwarding device in this application). The link type of the transmission link between the terminal device 11 and the uplink forwarding device 13 and the downlink forwarding device 14 is an access link. The link type of the transmission link between the base station 12 and the uplink forwarding device 13 and the downlink forwarding device 14 is a backhaul link. The terminal device 11, the base station 12, the uplink forwarding device 11, and the uplink forwarding device 12 can be connected in a wired manner or in a wireless manner, which is not limited in the embodiment of the present invention.

[0051] In the uplink direction (i.e., the direction in which the signal is transmitted from the terminal device to the base station), the uplink forwarding device 12 is used to forward the uplink signal sent by the terminal device 11 to the base station 12 when receiving the first indication information. Specifically, the uplink forwarding device 12 is used to receive the signal sent by the terminal device 11 by adjusting the direction of the uplink receiving beam of the access link, and forward the signal sent by the terminal device 11 to the base station 12 by adjusting the uplink transmitting beam of the backhaul link.

[0052] In the downlink direction (i.e., the direction in which the signal is transmitted from the base station to the terminal device), the downlink forwarding device 13 is used to forward the downlink signal sent by the base station 12 to the terminal device 11 when receiving the second indication information. Specifically, the downlink forwarding device 13 is used to receive the signal sent by the base station 12 by adjusting the direction of the downlink receiving beam of the backhaul link, and forward the signal sent by the base station 12 to the terminal device 11 by adjusting the downlink transmitting beam of the access link.

[0053] It should be noted that if Figure 1 As shown, it is assumed that there are multiple forwarding devices in the coverage area of ​​the base station 12. Since the uplink forwarding device 13 and the downlink forwarding device 14 are forwarding devices among the multiple forwarding devices, it can be known that the uplink forwarding device and the downlink forwarding device are forwarding devices controlled by the base station 12 in the relay communication system. That is, there is a control interface between the base station 12 and each of the multiple forwarding devices, which can be used to exchange control information. The terminal device 11 can be a terminal accessing the base station 12. The terminal device 11 can access the uplink forwarding device 13 and the downlink forwarding device 14 to communicate with the base station 12 through the uplink forwarding device 13 and the downlink forwarding device 14.

[0054] Optionally, the forwarding device may be integrated into the base station or may be an independent physical entity. The forwarding device may be a communication device such as RIS or NCR; the forwarding device designed in the embodiments of the present application mainly takes RIS or NCR as an example.

[0055] The communication system (i.e., the signal forwarding control system 10) in the embodiment of the present application can be a communication system based on RIS or NCR assistance, and the communication system includes a base station, a terminal device, and a plurality of forwarding devices. Both the base station and the terminal device support one or more of the fifth generation mobile communication technology (5th generation mobile communication technology-Advanced, 5G), 5G-A, 6G and other network standards. The forwarding device is an auxiliary communication device in the wireless communication system, which has multiple electromagnetic units and can implement electromagnetic control and radio frequency signal forwarding. The present application can be applied to a relay communication system including more than two forwarding devices.

[0056] A signal forwarding control method provided by an embodiment of the present application is described below in conjunction with the accompanying drawings. Figure 2 As shown, a signal forwarding control method provided in an embodiment of the present application is applied to an egress gateway, and the method includes S201:

[0057] S201. Send first indication information to a first forwarding device, and send second indication information to a second forwarding device.

[0058] Among them, the first indication information is used to instruct the first forwarding device (i.e., the uplink forwarding device) to forward the signal sent by the terminal device to the base station (i.e., the uplink signal); the second indication information is used to instruct the second forwarding device (i.e., the downlink forwarding device) to forward the signal sent by the base station to the terminal device (i.e., the downlink signal).

[0059] Optionally, when a terminal device connected to the base station needs to interact with the base station, the base station or other devices can determine the uplink forwarding device and downlink forwarding device to be accessed for the terminal device based on the location, performance parameters of the terminal device, the base station, and related information of multiple forwarding devices within the coverage area of ​​the base station.

[0060] Further, the first indication information is sent to the uplink forwarding device through the base station or other device, and the first indication information may include link direction indication information for indicating the forwarding link direction of the uplink forwarding device, and the forwarding link direction may be the direction in which the terminal device sends a signal to the base station, that is, the transmission direction of the uplink signal (also referred to as the uplink direction). In this way, when the uplink forwarding device receives the first indication information, it can forward the signal sent by the terminal device to the base station.

[0061] And, the second indication information is sent to the downlink forwarding device through the base station or other device, and the second indication information may include link direction indication information for indicating the forwarding link direction of the downlink forwarding device, and the forwarding link direction may be the direction in which the base station sends a signal to the terminal device, that is, the transmission direction of the downlink signal (also referred to as the downlink direction). In this way, when the downlink forwarding device receives the second indication information, it can forward the signal sent by the base station to the terminal device.

[0062] In one possible implementation, the first indication information and / or the second indication information includes at least one of the following: link direction indication information (i.e., Up Dwon Link Indication), a link identifier (i.e., Link Indication), a target beam identifier (i.e., beamIndex), and a forwarding resource identifier (i.e., FwdRsrcId); the link direction indication information is used to indicate the forwarding link direction of the forwarding device; the link identifier is used to indicate the link type of the link beam of the forwarding device; the target beam identifier is used to indicate the adjustment direction of the link beam of the forwarding device; and the forwarding resource identifier is used to indicate the forwarding resources configured by the base station for the forwarding device.

[0063] Optionally, the link direction indication information of the first indication information is used to indicate that the forwarding link direction of the uplink forwarding device is the uplink direction. The link direction indication information of the second indication information is used to indicate that the forwarding link direction of the downlink forwarding device is the downlink direction. The link identifier is used to indicate the link type of the link beam of the corresponding forwarding device, and the link type may be an access link or a backhaul link. The target beam identifier is used to indicate the adjustment direction of the link beam of the corresponding forwarding device. The forwarding resource identifier is used to indicate at least one of the multiple forwarding resources configured by the base station for the corresponding forwarding device. The multiple forwarding resources may include forwarding resources such as transmission time, transmission frequency, transmission power, and beam identifier.

[0064] Optionally, the base station or other device can determine the target beam direction (i.e., the adjustment direction of the link beam of the forwarding device) according to the location of the terminal device, the uplink forwarding device, the downlink forwarding device, and the base station, and then determine the target beam identifier corresponding to the target beam direction according to the correspondence between the beam direction and the beam identifier. The correspondence between the beam direction and the beam identifier can be pre-configured, and one beam direction corresponds to one beam identifier.

[0065] Alternatively, if Figure 1 As shown, the target beam direction between the terminal device and the uplink forwarding device can be the direction from the uplink forwarding device to the terminal device (i.e., the direction of the uplink receiving beam), so that. The uplink forwarding device can receive the uplink signal sent by the terminal device through the uplink receiving beam. The target beam direction between the terminal device and the downlink forwarding device can be the direction from the downlink forwarding device to the terminal device (i.e., the direction of the downlink transmitting beam), so that the downlink forwarding device can send a downlink signal to the terminal device through the downlink transmitting beam. The target beam direction between the base station and the uplink forwarding device can be the direction from the uplink forwarding device to the base station (i.e., the direction of the uplink transmitting beam). The target beam direction between the base station and the downlink forwarding device is the direction from the downlink forwarding device to the base station (i.e., the direction of the downlink receiving beam).

[0066] Furthermore, the correspondence between the beamforming codebook and the beam identifier may be pre-stored in the forwarding device. The beamforming codebook corresponds to a predefined set of directions, which is used to guide the forwarding device to adjust the beam direction during the beamforming process. Since the beam identifier and the beam direction corresponding to the beamforming codebook have a one-to-one correspondence, when the forwarding device receives the target beam identifier, it can query the correspondence between the beamforming codebook and the beam identifier to obtain the beamforming codebook corresponding to the target beam identifier, thereby adjusting the direction of the link beam to the beam direction corresponding to the target beam identifier according to the beamforming codebook.

[0067] It should be noted that there is a corresponding relationship between the target beam identifier and the forwarding resource identifier, that is, when the forwarding device receives the target beam identifier, it can obtain the forwarding resource identifier by querying the corresponding relationship between the target beam identifier and the forwarding resource identifier, and vice versa.

[0068] For example, Figure 1 As shown, if the link identifier of the first indication information indicates that the first indication information is used to configure the access link of the uplink forwarding device, the direction of the uplink receiving beam of the uplink forwarding device may be the direction from the uplink forwarding device to the terminal device. If the link identifier of the first indication information indicates that the first indication information is used to configure the backhaul link of the uplink forwarding device, the direction of the uplink transmitting beam of the uplink forwarding device may be the direction from the uplink forwarding device to the base station. If the link identifier of the second indication information indicates that the second indication information is used to configure the access link of the downlink forwarding device, the direction of the downlink transmitting beam of the downlink forwarding device may be the direction from the downlink forwarding device to the terminal device. If the link identifier of the second indication information indicates that the second indication information is used to configure the backhaul link of the downlink forwarding device, the direction of the downlink receiving beam of the downlink forwarding device may be the direction from the downlink forwarding device to the base station.

[0069] In a possible implementation manner, the message type of the indication information may be a radio resource control (Radio Resource Control, RRC) message, a media access control-control element (Media Access Control Control Element, MAC CE) message, or a downlink control information (Downlink Control Information, DCI) message, etc.

[0070] Optionally, when the message type of the indication information is an RRC message, the link direction indication information, link identifier, target beam identifier, and forwarding resource identifier can be sent in the form of information elements. That is, the indication information can include a link direction indication information element, a link identifier information element, a target beam identifier information element, and a forwarding resource identifier information element.

[0071] The link direction indication information element can be used to indicate that the target beam identifier or forwarding resource identifier carried in the control message is used to configure the uplink beam (i.e., the receiving beam or transmitting beam in the uplink direction) or downlink beam (i.e., the receiving beam or transmitting beam in the downlink direction) of the uplink forwarding device or the downlink forwarding device. The uplink beam includes at least one of the uplink receiving beam of the access link and the uplink transmitting beam of the backhaul link. The downlink beam includes at least one of the downlink transmitting beam of the access link and the downlink receiving beam of the backhaul link.

[0072] The link identification information element can be used to indicate that the target beam identification or forwarding resource identification carried in the control message is used to configure one of the beams of the access link or the beams of the backhaul link of the uplink forwarding device or the downlink forwarding device.

[0073] The target beam identifier information element may be used to indicate the adjustment direction of the forwarding beam to be configured of the corresponding forwarding device. The value of the target beam identifier may be an integer value type and may be at least one of the multiple beam identifiers currently configured by the corresponding forwarding device;

[0074] The forwarding resource identification information element is used to indicate at least one of the multiple forwarding resources configured by the base station for the corresponding forwarding device. The value of the forwarding resource identification information element can be an integer value type and is at least one of the multiple forwarding resource identifications currently configured for the corresponding forwarding device. The forwarding resources configured by the forwarding device include beam identification and corresponding transmission resources, etc.

[0075] In a possible implementation, when the message type of the indication information is an RRC message, the following configuration methods may be used to configure the link direction indication information element, the link identification information element, the target beam identification information element, and the forwarding resource identification information element.

[0076] Configuration method 1: The values ​​of the link direction indication cell and link identification cell can be configured as enumerated value types.

[0077] Exemplarily, the value of the enumeration value type can be True or False. When the control message received by the forwarding device carries a link direction indication cell, and the value of the cell is True (i.e., correct), the forwarding device can adjust the uplink beam according to the target beam identifier carried in the control message; when the control message received by the forwarding device carries a link direction indication cell, and the value of the cell is False (i.e., wrong), or when the control message received by the forwarding device does not carry a link direction indication cell, the forwarding device can adjust the downlink beam according to the target beam identifier carried in the control message.

[0078] When the control message received by the forwarding device carries a link identification cell, and the value of the cell is True, the forwarding device can adjust the beam of the access link according to the target beam identification carried in the control message. When the control message received by the forwarding device carries a link identification cell, and the value of the cell is False, or when the control message received by the forwarding device does not carry a link identification cell, the forwarding device can adjust the beam of the return link according to the target beam identification carried in the control message.

[0079] The code corresponding to configuration method 1 can be:

[0080]

[0081]

[0082] Configuration method 2: The values ​​of the link direction indication cell and the link identification cell can be configured as integer value types.

[0083] Exemplarily, the value of the integer numeric type may be Nr1 or Nr2. When the control message received by the forwarding device carries a link direction indication cell, and the value of the cell is 1 (i.e., Nr1), the forwarding device may adjust the uplink beam according to the target beam identifier carried in the control message; when the control message received by the forwarding device carries a link direction indication cell, and the value of the cell is 2 (i.e., Nr2), or when the control message received by the forwarding device does not carry a link direction indication cell, the forwarding device may adjust the downlink beam according to the target beam identifier carried in the control message.

[0084] When the control message received by the forwarding device carries a link identification cell, and the value of the cell is Nr1, the forwarding device can adjust the beam of the access link according to the target beam identification carried in the control message. When the control message received by the forwarding device carries a link identification cell, and the value of the cell is Nr2, or when the control message received by the forwarding device does not carry a link identification cell, the forwarding device can adjust the beam of the return link according to the target beam identification carried in the control message.

[0085] The code corresponding to configuration method 2 can be:

[0086]

[0087]

[0088] Configuration method three: The control message does not include a link direction indication information element, and the target beam identifier carried by the control message is used to adjust the uplink beam or the downlink beam by default. Also, the control message does not include a link identification information element, and the target beam identifier carried by the control message is used to adjust the beam of the access link or the beam of the return link by default.

[0089] Exemplarily, if the target beam identifier carried in the control message is used by default to adjust the uplink beam, then after the forwarding device receives the control message, the forwarding device adjusts the uplink beam according to the target beam identifier carried in the control message.

[0090] If the target beam identifier carried in the control message is used by default to adjust the beam of the access link, then after the forwarding device receives the control message, the forwarding device adjusts the beam of the access link according to the target beam identifier carried in the control message.

[0091] The code corresponding to configuration method three can be:

[0092]

[0093] Optionally, when the message type of the indication information is a MAC CE message, the link direction indication information, the link identifier, the target beam identifier, and the forwarding resource identifier may be sent in the form of fields. Indication information.

[0094] In a possible implementation, when the message type of the indication information is a MAC CE message, the following configuration methods may be used to configure the link direction indication, link identifier, target beam identifier, and forwarding resource identifier.

[0095] Configuration method 1: Figure 3 FIG. 1 is a schematic diagram of a configuration method 1 of a MAC CE message, such as Figure 3 As shown, the indication information may include a beamIndex field, a D field, an L field, and an R field. The beamIndex field is used to indicate a beam identifier corresponding to at least one forwarding resource in a forwarding resource set (i.e., FwdRsrcList). beamIndex0 indicates the beam identifier corresponding to the first forwarding resource in FwdRsrcList, beamIndex1 indicates the beam identifier corresponding to the second forwarding resource in the forwarding resource set, and so on. The number N of beam identifiers is equal to the number of beam identifiers contained in the forwarding resource set.

[0096] The D field is a link direction indication field, which is used to indicate the uplink direction or the downlink direction. If the value of this field is set to 1, the forwarding resources indicated by the FwdRsrcId of the RRC information element will be applied to the transmission or reception of uplink signals. If the value of this field is set to 2, the forwarding resources indicated by the FwdRsrcId will be applied to the transmission or reception of downlink signals.

[0097] The L field is used to indicate an access link or a backhaul link. If the value of this field is set to 1, the forwarding resources indicated by the FwdRsrcId of the RRC information element will be applied to the transmission or reception on the access link. If the value of this field is set to 2, the forwarding resources indicated by the FwdRsrcId will be applied to the transmission or reception on the backhaul link. The R field is a reserved bit.

[0098] Configuration method 2: Figure 4 FIG. 1 is a schematic diagram of a second configuration mode of a MAC CE message, such as Figure 4 As shown, the indication information may include a beamIndex field and an R field. Also, different types of MAC CE messages may be configured with different MAC headers (MAC subheaders), that is, different types of MAC CE messages may be distinguished by different MAC headers (different values ​​are set for the header fields).

[0099] beamIndex field: used to indicate the beam identifier corresponding to at least one forwarding resource in FwdRsrcList. beamIndex0 indicates the beam identifier corresponding to the first forwarding resource in FwdRsrcList, beamIndex1 indicates the beam identifier corresponding to the second forwarding resource in the forwarding resource set, and so on. The number of beam identifiers N is equal to the number of beam identifiers contained in the forwarding resource set. The R field is a reserved bit.

[0100] Exemplarily, when the MAC header is a value of 1, the MAC CE message is used to indicate that the forwarding resource set carried in the control message is used to configure the uplink beam. When the MAC header is a value of 2, the MAC CE message is used to indicate that the forwarding resource set carried in the control message is used to configure the downlink beam. When the MAC header is a value of 3, the MAC CE message is used to indicate that the forwarding resource set carried in the control message is used to configure the beam of the access link. When the MAC header is a value of 4, the MAC CE message is used to indicate that the forwarding resource set carried in the control message is used to configure the beam of the backhaul link.

[0101] Optionally, when the message type of the indication information is a DCI message, the link direction indication information, the link identifier, the target beam identifier, and the forwarding resource identifier may be sent in the form of fields. Indication information.

[0102] In a possible implementation, when the message type of the indication information is a DCI message, the following configuration method may be used to configure the link direction indication, link identifier, target beam identifier, and forwarding resource identifier. The indication information may include the following fields: beamIndex0, beamIndex1, ..., beamIndex N-1, FwdRsrcId0, FwdRsrcId1, ..., FwdR srcIdN-1, UpDwonLinkIndication, LinkIndication.

[0103] Among them, beamIndex0 corresponds to FwdRsrcId0 one by one, N is equal to the number of beam identifiers contained in the forwarding resource set, beamIndex0 and subBandIndex0 correspond to the first forwarding resource in FwdRsrcList (the corresponding forwarding resource identifier has the smallest value, FwdRsrcId=0).

[0104] Exemplarily, if the RRC layer parameters include the UpDwonLinkIndication information element, the DCI includes the UpDwonLinkIndication field; otherwise, the DCI does not include the field. If the RRC layer parameters include the LinkIndication information element, the DCI includes the LinkIndication field; otherwise, the DCI does not include the field.

[0105] The present application can send a control message to the corresponding forwarding device, and can instruct the corresponding forwarding device to adjust the uplink beam or downlink beam according to the forwarding resource identifier or the target beam identifier, so that the corresponding forwarding device is used to forward the uplink signal or downlink signal of the terminal device. In the related art, the same forwarding resource is used for both downlink signal and uplink signal forwarding, and it is impossible to independently configure forwarding resources or target beams for uplink signal or downlink signal forwarding, resulting in low transmission performance of downlink and uplink signals. In response to the problems in the related art, the present application can independently configure different forwarding devices and forwarding resources for uplink beams and downlink beams by carrying link direction indication information in the control message, so that the terminal device can access different forwarding devices for sending and receiving uplink signals and downlink signals respectively, and can adapt the best forwarding devices for uplink signal and downlink signal transmission respectively, thereby improving the transmission performance of uplink and downlink signals at the same time.

[0106] In one design, Figure 5 As shown, a signal forwarding control method provided by an embodiment of the present application, before the above step S201, the method further includes S301-S302:

[0107] S301. Obtain device information of a terminal device, a base station, and multiple forwarding devices within the coverage area of ​​the base station.

[0108] The device information includes the location and / or performance parameters of the corresponding device.

[0109] Optionally, the base station or other equipment may obtain equipment information of the terminal equipment, the base station, and multiple forwarding devices within the coverage area of ​​the base station.

[0110] Optionally, the base station may obtain the location of the terminal device, the location of the base station itself, and the location of each forwarding device based on the base station positioning technology. The terminal device may also obtain its location based on the terminal positioning technology and report it to the base station or other devices. The forwarding device may also obtain its location based on its own positioning technology and report it to the base station or other devices. The location may be a parameter representing the location such as longitude and latitude coordinates.

[0111] In a possible implementation, the performance parameter includes at least one of the following: uplink minimum transmission rate, uplink maximum transmission delay, downlink minimum transmission rate, downlink maximum transmission delay, and the number of access terminal devices. Among them, the uplink minimum transmission rate, uplink maximum transmission delay, downlink minimum transmission rate, and downlink maximum transmission delay are transmission performance parameters of the terminal device, which are used to reflect the minimum transmission performance requirements of the terminal device. The number of access terminal devices is a transmission performance parameter of the forwarding device, which is used to reflect the number of terminal devices that have accessed the forwarding device.

[0112] S302: Determine a first forwarding device and a second forwarding device from a plurality of forwarding devices based on the device information.

[0113] Optionally, the base station or other device may determine the first forwarding device and the second forwarding device from a plurality of forwarding devices based on the device information.

[0114] It should be noted that, for a specific description of how to determine the first forwarding device and the second forwarding device from multiple forwarding devices based on the device information, reference may be made to the following embodiments, which will not be described in detail here.

[0115] The present application can independently determine the corresponding uplink forwarding device and downlink forwarding device according to the location, performance parameters and other information of the terminal device, base station, and multiple forwarding devices. That is, the uplink forwarding device and the downlink forwarding device are decoupled, and the uplink signal and the downlink signal of the terminal are forwarded respectively through different forwarding devices. When there is a difference in the transmission performance of the uplink and downlink links, the uplink signal and the downlink signal can be adapted to the optimal forwarding device respectively, thereby improving the transmission performance of the uplink and downlink links.

[0116] In one design, Figure 6As shown, a signal forwarding control method provided by an embodiment of the present application, before the above step S201, the method further includes: S401-S402, or, S401-S403:

[0117] S401. Based on the positions of the terminal device and the multiple forwarding devices, determine the distance between the terminal device and each of the multiple forwarding devices, and the distance between the base station and each of the multiple forwarding devices.

[0118] Optionally, the base station or other device may determine the distance between the terminal device and each of the multiple forwarding devices, and the distance between the base station and each of the multiple forwarding devices based on the positions of the terminal device and the multiple forwarding devices.

[0119] Exemplarily, it is assumed that the number of the multiple forwarding devices is 4, namely forwarding device 1, forwarding device 2, forwarding device 3, and forwarding device 4. The distance between the terminal device and forwarding device 1 is 50 meters, the distance between the terminal device and forwarding device 2 is 100 meters, the distance between the terminal device and forwarding device 3 is 150 meters, and the distance between the terminal device and forwarding device 4 is 200 meters. The distance between the base station and forwarding device 1 is 50 meters, the distance between the base station and forwarding device 2 is 100 meters, the distance between the base station and forwarding device 3 is 150 meters, and the distance between the base station and forwarding device 4 is 200 meters.

[0120] S402: Determine a first forwarding device from among multiple forwarding devices, the distance between which and the terminal device is less than a first value.

[0121] Optionally, the base station or other device may determine the first forwarding device from the forwarding devices whose distances to the terminal device are less than a first value, based on the distances between the terminal device and each of the multiple forwarding devices. Furthermore, if there are multiple forwarding devices whose distances are less than the first value, the first forwarding device may be randomly determined from the forwarding devices whose distances are less than the first value, or the device whose distance to the terminal device is the smallest among the forwarding devices whose distances are less than the first value may be determined as the first forwarding device, or multiple forwarding devices whose distances are less than the first value may be determined as the first forwarding device.

[0122] Exemplarily, assuming that the first value may be 150 meters, then the forwarding devices with a distance less than 150 meters include forwarding device 1 and forwarding device 2, and both forwarding device 1 and forwarding device 2 may be first forwarding devices.

[0123] S403: Determine a second forwarding device from among the multiple forwarding devices, the distance between the forwarding devices and the base station being less than a second value.

[0124] Optionally, the base station or other device may determine the second forwarding device from the forwarding devices whose distance to the terminal device is less than the second value, based on the distance between the base station and each of the multiple forwarding devices. Furthermore, if there are multiple forwarding devices whose distance is less than the second value, the second forwarding device may be randomly determined from the forwarding devices whose distance is less than the second value, or the device whose distance to the base station is the shortest among the forwarding devices whose distance is less than the second value may be determined as the second forwarding device, or multiple forwarding devices whose distance is less than the second value may be determined as the second forwarding device.

[0125] Exemplarily, assume that the second value can be 150 meters. Then the forwarding devices less than 150 meters are forwarding device 1 and forwarding device 2, and both forwarding device 1 and forwarding device 2 can be second forwarding devices. The present application can determine a forwarding device that is close to the terminal device as an uplink forwarding device, and determine a forwarding device that is close to the base station as a downlink forwarding device. This is because, when the forwarding device receives a signal, the closer the distance to the device that sends the signal, the greater the incident signal strength, and the higher the quality of the forwarding signal of the forwarding device. Thereby, the uplink incident signal strength and the downlink incident signal strength of the forwarding device can be improved, thereby improving the quality of the forwarded signal and enhancing the uplink and downlink transmission performance of the terminal device.

[0126] In one design, Figure 7 As shown, a signal forwarding control method provided in an embodiment of the present application, before the above step S201, the method further includes S501, S502, S503, or S504:

[0127] S501. When the uplink minimum transmission rate is greater than a third value and / or the uplink maximum transmission delay is less than or equal to a fourth value, determine a first forwarding device from among multiple forwarding devices, the number of access terminal devices of which is less than a fifth value.

[0128] Optionally, the base station or other device may determine whether the uplink minimum transmission rate is greater than a third value and / or whether the uplink maximum transmission delay is less than or equal to a fourth value. Further, in the case where the uplink minimum transmission rate is greater than the third value and / or the uplink maximum transmission delay is less than or equal to the fourth value, the base station or other device may determine the first forwarding device from the forwarding devices whose number of access terminal devices is less than a fifth value among multiple forwarding devices. Further, if there are multiple forwarding devices whose number of access terminal devices is less than the fifth value, the first forwarding device may be randomly determined from the forwarding devices whose number of access terminal devices is less than the fifth value, the device with the least number of access terminal devices may be determined as the first forwarding device, or multiple forwarding devices whose number of access terminal devices is less than the fifth value may be determined as the first forwarding device.

[0129] For example, the third value may be any reasonable value such as 8 bps, 9 bps, etc., the fourth value may be any reasonable value such as 1 ms, 2 ms, etc., and the fifth value may be any reasonable value such as 20 units.

[0130] It should be noted that the minimum transmission rate and maximum transmission delay of the terminal device can be used to reflect the minimum transmission performance requirements of the terminal device. The larger the minimum transmission rate and the smaller the maximum transmission delay, the higher the transmission performance requirements of the terminal device. The smaller the minimum transmission rate and the larger the maximum transmission delay, the lower the transmission performance requirements of the terminal device. The number of terminal devices connected to the forwarding device can reflect the load rate of the forwarding device. The more terminal devices connected to the forwarding device and the greater the load rate, the fewer forwarding resources can be configured for the target forwarding device, and the worse the transmission performance of the forwarding device, and vice versa.

[0131] S502: When the uplink minimum transmission rate is less than or equal to a third value and / or the uplink maximum transmission delay is greater than a fourth value, determine a first forwarding device from among a plurality of forwarding devices, the distance between the forwarding device and the terminal device being less than a first value.

[0132] Optionally, when the uplink minimum transmission rate is less than or equal to the third value and / or the uplink maximum transmission delay is greater than the fourth value, the base station or other device may determine the first forwarding device from among the multiple forwarding devices the forwarding devices whose distance to the terminal device is less than the first value. If there are multiple forwarding devices whose distance is less than the first value, the first forwarding device may be randomly determined from among the forwarding devices whose distance is less than the first value, or the device whose distance to the terminal device is the shortest among the forwarding devices whose distance is less than the first value may be determined as the first forwarding device, or multiple forwarding devices whose distance to the terminal device is less than the first value may be determined as the first forwarding device.

[0133] S503: When the downlink minimum transmission rate is greater than the third value and / or the downlink maximum transmission delay is less than or equal to the fourth value, determine a second forwarding device from among the multiple forwarding devices the number of which access terminal devices is less than a fifth value.

[0134] Optionally, the base station or other device may determine whether the minimum downlink transmission rate is greater than a third value and / or whether the maximum uplink transmission delay is less than or equal to a fourth value. In the case where the minimum downlink transmission rate is greater than the third value and / or the maximum downlink transmission delay is less than or equal to the fourth value, the base station or other device may determine the second forwarding device from the forwarding devices whose number of access terminal devices is less than a fifth value among the multiple forwarding devices. Furthermore, if there are multiple forwarding devices whose number of access terminal devices is less than the fifth value, the second forwarding device may be randomly determined from the forwarding devices whose number of access terminal devices is less than the fifth value, the device with the least number of access terminal devices may be determined as the second forwarding device, or multiple forwarding devices whose number of access terminal devices is less than the fifth value may be determined as the second forwarding device.

[0135] S504: When the minimum downlink transmission rate is less than or equal to the third value and / or the maximum downlink transmission delay is greater than the fourth value, determine a second forwarding device from among multiple forwarding devices, the forwarding devices whose distance to the terminal device is less than the second value.

[0136] Optionally, when the downlink minimum transmission rate is less than or equal to the third value and / or the downlink maximum transmission delay is greater than the fourth value, the base station or other device may determine the second forwarding device from among the multiple forwarding devices the forwarding devices whose distance to the terminal device is less than the second value. Furthermore, if there are multiple forwarding devices whose distance is less than the second value, the second forwarding device may be randomly determined from among the forwarding devices whose distance is less than the second value, or the device whose distance to the base station is the shortest among the forwarding devices whose distance is less than the second value may be determined as the second forwarding device, or multiple forwarding devices whose distance is less than the second value may be determined as the second forwarding device.

[0137] In the case where the transmission performance requirements of the terminal device are high, the present application can select a forwarding device with a small number of access terminal devices for the service transmission of the terminal device, so that more forwarding resources can be configured for the forwarding device to improve the transmission performance. Also, in the case where the transmission performance requirements of the terminal device are not high, a forwarding device that is closer to the terminal is selected, so that the signal transmission path loss is reduced, the signal reception strength is improved, and the transmission performance of the terminal device is improved.
