Specifically, the third generation partnership project (3 rd Generation Partnership Project Release-18,3GPP Rel-18) based on the Rel-18 protocol standard proposes network controlled NCR technology on the basis of a radio frequency repeater. Compared with the traditional radio frequency repeater, the NCR is a radio frequency repeater with the capability of receiving and processing control information from a network side. The NCR can be used as a forwarding device in a relay communication system, and based on control information issued by a network side, the amplifying and forwarding strategy of the NCR is optimally controlled, and the forwarding beam (also called as a link beam) of the NCR is adjusted, so that the signal amplifying and forwarding efficiency is effectively improved.
RIS is used as a two-dimensional implementation of electromagnetic metamaterial, and the spatial electromagnetic wave is actively and intelligently regulated and controlled in a programmable manner to form an electromagnetic field with controllable amplitude, phase, polarization and frequency. RIS is used as a carrier for electromagnetic regulation and control and is generally composed of a series of electromagnetic unit structures which are periodically arranged. The electromagnetic unit structure may integrate some tunable elements (such as P-type semiconductor-impurity-N-type semiconductor (PIN) diode, varactor, liquid crystal, micro-electro-MECHANICAL SYSTEM (MEMS) switch, etc.) to obtain the reconfigurability of electromagnetic wave control. The introduction of RIS changes the wireless propagation environment from passive adaptation to active control, thereby constructing an intelligent wireless environment. The RIS can remarkably improve the transmission performance between communication devices and enhance the coverage performance of a wireless communication system by dynamically adjusting the wireless channel environment. In the relay communication system, an RIS may be used as a forwarding device to assist in enhancing coverage capability of the base station, especially when coverage is performed at a cell edge and a blind spot area, a signal sent by the base station is forwarded (reflected/transmitted) to the terminal device through the RIS, and a signal sent by the terminal device may also be forwarded to the base station through the RIS. In order to expand the coverage of the base station and suppress interference, the RIS needs to direct the forward beam of the RIS to a specific terminal device by beamforming.
In summary, the forwarding beam can be regulated and controlled by a forwarding device in the area where the base station is located based on technologies such as beam forming, so that the forwarding beam is directed to a terminal device or the base station in the coverage area, signals transmitted between the terminal device and the base station are forwarded, the power of the signals is enhanced, and communication between the terminal device and the base station is assisted. However, when the signal transmitted between the terminal device and the base station includes an uplink signal and a downlink signal, and the forwarding device is used for forwarding the uplink signal and the downlink signal between the terminal device and the base station, the efficiency of forwarding the signal by the forwarding device is poor. And before the forwarding device regulates and controls the forwarding beam, the optimal forwarding device to be accessed by the terminal device needs to be determined. Particularly, when a plurality of forwarding devices exist, the terminal device may access different forwarding devices to obtain different communication performances, and if the terminal device may access the forwarding devices, the efficiency of forwarding signals by the forwarding devices is poor, which results in lower signal transmission performance.
In order to solve the above-mentioned problems, the present application provides a signal forwarding control method, which determines an uplink forwarding device (i.e. a first forwarding device) and a downlink forwarding device (i.e. a second forwarding device) for uplink and downlink signal transmission of a terminal device according to information such as access parameters (e.g. location, performance parameters, etc.) of the terminal device. By sending control messages (which may also be referred to as indication information) to the uplink forwarding device and the downlink forwarding device, respectively, the corresponding forwarding device is indicated to be used for forwarding the uplink signal and the downlink signal of the terminal device, respectively. Further, the uplink forwarding device and the downlink forwarding device respectively adjust a receiving beam and a transmitting beam on the link according to the indication information, so as to forward uplink signals and downlink signals of the terminal device. Therefore, the optimal forwarding equipment can be selected and accessed for the terminal equipment, and the transmission performance of uplink signals and downlink signals is improved.
The signal forwarding control method provided by the embodiment of the application can be applied to a signal forwarding control system. Fig. 1 shows a schematic diagram of a signal forwarding control system. As shown in fig. 1, the signal forwarding control system 10 includes a terminal device 11, a base station 12, an upstream forwarding device 13 (i.e., a first forwarding device in the present application), and a downstream forwarding device 14 (i.e., a second forwarding device in the present 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 may be connected by a wired manner or may be connected by a wireless manner, which is not limited in the embodiment of the present application.
In the uplink direction (i.e. the direction in which signals are transmitted from the terminal device to the base station), the uplink forwarding device 12 is configured to forward uplink signals sent by the terminal device 11 to the base station 12 when receiving the first indication information. Specifically, the uplink forwarding device 12 is configured to receive a signal sent by the terminal device 11 by adjusting a direction of an uplink receiving beam of the access link, and forward the signal sent by the terminal device 11 to the base station 12 by adjusting an uplink sending beam of the backhaul link.
In the downlink direction (i.e. the direction in which signals are transmitted from the base station to the terminal device), the downlink forwarding device 13 is configured to forward downlink signals sent by the base station 12 to the terminal device 11 when receiving the second indication information. Specifically, the downlink forwarding device 13 is configured to receive a signal sent by the base station 12 by adjusting a direction of a downlink receiving beam of the backhaul link, and forward the signal sent by the base station 12 to the terminal device 11 by adjusting a downlink sending beam of the access link.
As shown in fig. 1, assuming that there are a plurality of 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 plurality of forwarding devices, it is 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. I.e. there is a control interface between the base station 12 and each of the plurality of forwarding devices, which can be used for exchanging control information. The terminal device 11 may be a terminal accessing the base station 12, and the terminal device 11 may 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.
Alternatively, the forwarding device may be integrated in the base station or may be a separate physical entity. The forwarding device may be communication devices such as RIS and NCR, and the forwarding device designed in the embodiment of the application mainly takes RIS or NCR as an example.
The communication system (i.e., signal forwarding control system 10) in an embodiment of the present application may be an RIS or NCR-based assisted communication system including a base station, a terminal device, and a plurality of forwarding devices.

The present application is applicable to a relay communication system including two or more forwarding devices.
The following describes a signal forwarding control method provided by an embodiment of the present application with reference to the accompanying drawings. As shown in fig. 2, the signal forwarding control method provided by the embodiment of the present application is applied to an egress gateway, and the method includes S201:
S201, sending first indication information to the first forwarding device and sending second indication information to the second forwarding device.
The first indication information is used for indicating the first forwarding device (i.e. the uplink forwarding device) to forward a signal (i.e. an uplink signal) sent by the terminal device to the base station, and the second indication information is used for indicating the second forwarding device (i.e. the downlink forwarding device) to forward the signal (i.e. a downlink signal) sent by the base station to the terminal device.
Optionally, under the condition that a certain terminal device connected with the base station needs to interact with the base station, the base station or other devices can respectively determine the uplink forwarding device and the downlink forwarding device to be accessed according to the position, the performance parameters and the related information of a plurality of forwarding devices in the coverage areas of the base station and the base station for the terminal device.
Further, the first indication information may include link direction indication information for indicating a forwarding link direction of the uplink forwarding device, where the forwarding link direction may be a direction in which the terminal device sends a signal to the base station, that is, a transmission direction of the uplink signal (may also be referred to as an uplink direction) by the base station or other devices. In this way, when the uplink forwarding device receives the first indication information, the signal sent by the terminal device to the base station can be forwarded.
And transmitting, by the base station or other device, second indication information to the downlink forwarding device, where the second indication information may include link direction indication information for indicating a forwarding link direction of the downlink forwarding device, where the forwarding link direction may be a direction in which the base station transmits a signal to the terminal device, that is, a transmission direction of a downlink signal (may also be referred to as a downlink direction). In this way, the downlink forwarding device can forward the signal sent by the base station to the terminal device when receiving the second indication information.
In one possible implementation, the first Indication information and/or the second Indication information includes at least one of Link direction Indication information (i.e., up Dwon Link Indication), link identification (i.e., link Indication), target beam identification (i.e., beamIndex), and forwarding resource identification (i.e., FWDRSRCID), the Link direction Indication information is used to indicate a forwarding Link direction of the forwarding device, the Link identification is used to indicate a Link type of a Link beam of the forwarding device, the target beam identification is used to indicate an adjustment direction of a Link beam of the forwarding device, and the forwarding resource identification is used to indicate forwarding resources configured by the base station for the forwarding device.
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 an uplink direction. The link direction indication information of the second indication information is used for indicating that the forwarding link direction of the downlink forwarding device is the downlink direction. The link identification is used to indicate the link type of the link beam of the corresponding forwarding device, which may be an access link or a backhaul link. The target beam identification is used to indicate the adjustment direction of the link beam of the corresponding forwarding device. The forwarding resource identification is used to instruct the base station to configure at least one of a plurality of forwarding resources for the corresponding forwarding device. The plurality of forwarding resources may include forwarding resources such as transmission time, transmission frequency, transmission power, beam identification, etc.
Optionally, the base station or other devices may determine the target beam direction (i.e. the adjustment direction of the link beam of the forwarding device) according to the positions of the terminal device, the uplink forwarding device, the downlink forwarding device and the base station, and further 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 directions and the beam identities may be preconfigured, with one beam direction corresponding to one beam identity.
Alternatively, as shown in fig. 1, the target beam direction between the terminal device and the upstream forwarding device may be a direction from the upstream forwarding device to the terminal device (i.e., a direction of the upstream reception beam), so that. The uplink forwarding device may receive, through an uplink reception beam, an uplink signal sent by the terminal device. The target beam direction between the terminal device and the downstream forwarding device may be a direction from the downstream forwarding device to the terminal device (i.e., a direction of the downstream transmission beam), so that the downstream forwarding device may transmit the downstream signal to the terminal device through the downstream transmission beam. The target beam direction between the base station and the upstream forwarding device may be the direction from the upstream forwarding device to the base station (i.e. the direction of the upstream transmit beam). The target beam direction between the base station and the downstream forwarding device is the direction from the downstream forwarding device to the base station (i.e. the direction of the downstream receive beam).
Further, the forwarding device may pre-store a correspondence between the beamforming codebook and the beam identifier. The beamforming codebook corresponds to a predefined set of directions for guiding the forwarding device to adjust the beam direction during beamforming. Because the beam identifications and the beam directions corresponding to the beam forming codebooks have a one-to-one correspondence, when receiving the target beam identifications, the forwarding device can obtain the beam forming codebook corresponding to the target beam identifications by inquiring the correspondence between the beam forming codebooks and the beam identifications, so that the direction of the link beam is adjusted to the beam direction corresponding to the target beam identifications according to the beam forming codebook.
It should be noted that, the target beam identifier has a corresponding relationship with the forwarding resource identifier, that is, when the forwarding device receives the target beam identifier, the forwarding device may learn the forwarding resource identifier by querying the corresponding relationship between the target beam identifier and the forwarding resource identifier, and vice versa.
For example, as shown in fig. 1, 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 reception beam of the uplink forwarding device may be a 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 uplink transmission beam of the uplink forwarding device may be directed from the uplink forwarding device to the base station. If the link identification 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 transmission beam of the downlink forwarding device may be a 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 reception beam of the downlink forwarding device may be a direction pointing from the downlink forwarding device to the base station.
In one possible implementation, 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.
Optionally, when the message type of the indication information is an RRC message, the link direction indication information, the link identifier, the target beam identifier, and the forwarding resource identifier may be sent by means of a cell. I.e. the indication information may comprise a link direction indication cell, a link identification cell, a target beam identification cell, a forwarding resource identification cell.
The link direction indication information element may be used to indicate a target beam identifier or a forwarding resource identifier carried in the control message to configure an uplink beam (i.e. a receive beam or a transmit beam in an uplink direction) or a downlink beam (i.e. a receive beam or a transmit beam in a downlink direction) of the uplink forwarding device or the downlink forwarding device. The uplink beam comprises at least one of an uplink receive beam of the access link and an uplink transmit beam of the backhaul link. The downstream beam comprises at least one of a downstream transmit beam of the access link and a downstream receive beam of the backhaul link.
The link identification information element may be configured to indicate a target beam identification or a forwarding resource identification carried in the control message for configuring one of a beam of an access link or a beam of a backhaul link of the uplink forwarding device or the downlink forwarding device.
The target beam identification cell may be used to indicate the adjustment direction of the forwarding beam to be configured of the corresponding forwarding device. The target beam identifier may be of an integer number type and be at least one of a plurality of beam identifiers currently configured by the corresponding forwarding device;
And the forwarding resource identification information element is used for indicating at least one of a plurality of forwarding resources configured by the base station for the corresponding forwarding equipment, and the value of the forwarding resource identification information element can be an integer value type and is at least one of a plurality of forwarding resource identifications currently configured by the corresponding forwarding equipment. The forwarding resources configured by the forwarding device comprise beam identifiers, corresponding transmission resources and the like.
In one possible implementation, when the message type of the indication information is an RRC message, the link direction indication cell, the link identification cell, the target beam identification cell, and the forwarding resource identification cell may be configured in several configurations.
Configuration one, the value of the link direction indication cell and the link identification cell may be configured to enumerate a numeric type.
Illustratively, the enumerated value type may be True, false. When the control information received by the forwarding device carries the link direction indication information element, and the value of the information element is True (i.e. correct), the forwarding device can adjust the uplink beam according to the target beam identifier carried in the control information, when the control information received by the forwarding device carries the link direction indication information element, and the value of the information element is False (i.e. incorrect), or when the control information received by the forwarding device does not carry the link direction indication information element, the forwarding device can adjust the downlink beam according to the target beam identifier carried in the control information.
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 link identification cell in the control message received by the forwarding device is False, or when the control message received by the forwarding device does not carry the 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.
The configuration mode one corresponding code may be:
and in the second configuration mode, the value of the link direction indication cell and the link identification cell can be configured into an integer numerical value type.
Illustratively, the integer numeric value type may have values of Nr1, nr2. When the control information received by the forwarding device carries the link direction indication cell and the value of the cell is 1 (namely Nr 1), the forwarding device can adjust the uplink beam according to the target beam mark carried in the control information, when the control information received by the forwarding device carries the link direction indication cell and the value of the cell is 2 (namely Nr 2), or when the control information received by the forwarding device does not carry the link direction indication cell, the forwarding device can adjust the downlink beam according to the target beam mark carried in the control information.
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 link identification cell in the control message received by the forwarding device is Nr2, or when the control message received by the forwarding device does not carry the link identification cell, the forwarding device may adjust the beam of the backhaul link according to the target beam identification carried in the control message.
The code corresponding to the configuration mode II can be:
And in the third configuration mode, the control message does not comprise a link direction indication cell, and the target beam identifier carried by the control message is used for adjusting the uplink beam or the downlink beam by default. And the control message does not comprise a link identification cell, and the target beam identification carried by the control message is used for adjusting the beam of the access link or the beam of the return link by default.
For example, if the target beam identifier carried by the control message is used to adjust the uplink beam by default, 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.
If the target beam identifier carried by the control message is used for adjusting the beam of the access link by default, 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 by the control message.
The code corresponding to the configuration mode three can be:
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 by field. Indication information.
In one possible implementation, when the message type of the indication information is a MAC CE message, the following configurations may be used to configure the link direction indication, the link identification, the target beam identification, and the forwarding resource identification.
Configuration one as shown in fig. 3, a schematic diagram of a configuration one of a MAC CE message, and as shown in fig. 3, the indication information may include beamIndex fields, D fields, L fields, and R fields. The beamIndex field is used to indicate the beam identity corresponding to at least one forwarding resource in the set of forwarding resources (i.e., FWDRSRCLIST). beamIndex 0a indicates a beam identity corresponding to a first one of the forwarding resources FWDRSRCLIST, beamIndex a beam identity corresponding to a second one of the forwarding resources set, and so on, the number N of beam identities being equal to the number of beam identities comprised by the forwarding resource set.
The D field is a link direction indication field for indicating an uplink direction or a downlink direction. If the value of this field is set to a value of 1, the forwarding resource indicated by FWDRSRCID of the RRC cell will be applied to the transmission or reception of the uplink signal. If the value of this field is set to a value of 2, then the forwarding resource indicated by FWDRSRCID will be applied to the transmission or reception of downstream signals.
The L field is used to indicate the access link or backhaul link. If the value of this field is set to a value of 1, the forwarding resource indicated by FWDRSRCID of the RRC cell will be applied to either transmission or reception on the access link. If the value of this field is set to a value of 2, then the forwarding resource indicated by FWDRSRCID will be applied to either transmission or reception on the backhaul link. The R field is a reserved bit.
Fig. 4 is a schematic diagram of a configuration mode two of a MAC CE message, and as shown in fig. 4, the indication information may include beamIndex fields and R fields. And, different types of MAC CE messages may be configured with different MAC headers (MAC subheader), i.e., different types of MAC CE messages may be distinguished by different MAC headers (with different values set for the header fields).
BeamIndex field, which is used to indicate the beam identifier corresponding to at least one forwarding resource in FWDRSRCLIST. beamIndex 0a indicates a beam identity corresponding to a first one of the forwarding resources FWDRSRCLIST, beamIndex a beam identity corresponding to a second one of the forwarding resources set, and so on, the number N of beam identities being equal to the number of beam identities comprised by the forwarding resource set. The R field is a reserved bit.
For example, 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.
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 by field. Indication information.
In one possible implementation, when the message type of the indication information is a DCI message, the link direction indication, the link identification, the target beam identification, and the forwarding resource identification may be configured in the following configuration manner. The indication information may include the following fields :beamIndex0,beamIndex1,…,beamIndex N-1、FwdRsrcId0,FwdRsrcId1,…,FwdR srcIdN-1、UpDwonLinkIndication、LinkIndication.
Wherein beamIndex and FWDRSRCID0 are in one-to-one correspondence, 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).
Illustratively, if the RRC layer parameter includes UpDwonLinkIndication cells, the DCI contains field UpDwonLinkIndication, otherwise, the DCI does not contain this field. The DCI contains field LinkIndication if the RRC layer parameters include LinkIndication cells, otherwise the DCI does not contain this field.
The application can instruct the corresponding forwarding device to adjust the uplink beam or the downlink beam according to the forwarding resource identification or the target beam identification by sending the control message to the corresponding forwarding device, so that the corresponding forwarding device is used for forwarding the uplink signal or the downlink signal of the terminal device. In the related art, the same forwarding resource is simultaneously applied to forwarding of downlink signals and uplink signals, and forwarding resources or target beams cannot be configured for uplink signals or downlink signal forwarding independently, so that the transmission performance of the downlink signals and the uplink signals is low. Aiming at the problems in the related art, the application can realize that different forwarding devices and forwarding resources are independently configured for the uplink beam and the downlink beam by carrying the link direction indication information in the control message, so that the terminal device can be connected into different forwarding devices for respectively receiving and transmitting uplink signals and downlink signals, and can be respectively matched with the optimal forwarding devices for the transmission of the uplink signals and the downlink signals, thereby simultaneously improving the transmission performance of the uplink signals and the downlink signals.
In one design, as shown in fig. 5, in the signal forwarding control method provided by the embodiment of the present application, before the step S201, the method further includes S301 to S302:
s301, acquiring equipment information of a terminal equipment, a base station and a plurality of forwarding equipment in the coverage area of the base station.
Wherein the device information comprises a location and/or performance parameter of the corresponding device.
Alternatively, the base station or other device may obtain device information for the terminal device, the base station, and a plurality of forwarding devices within the coverage area of the base station.
Alternatively, 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 base station positioning techniques. The terminal device can also acquire its position based on the terminal positioning technology and report it to the base station or other devices. The forwarding device may also acquire 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 latitude and longitude coordinates.
In one possible implementation, the performance parameter includes at least one of an uplink minimum transmission rate, an uplink maximum transmission delay, a downlink minimum transmission rate, a downlink maximum transmission delay, and a number of access terminal devices. The uplink minimum transmission rate, the uplink maximum transmission delay, the downlink minimum transmission rate and the downlink maximum transmission delay are transmission performance parameters of the terminal equipment and are used for reflecting the minimum transmission performance requirement of the terminal equipment. The number of access terminal devices is a transmission performance parameter of the forwarding device, and is used for reflecting the number of terminal devices that have access to the forwarding device.
S302, determining a first forwarding device and a second forwarding device from a plurality of forwarding devices based on the device information.

It should be noted that, for a specific description of how to determine the first forwarding device and the second forwarding device from the plurality of forwarding devices based on the device information, reference may be made to the following embodiments, which are not described herein.
The application can respectively and independently determine the corresponding uplink forwarding equipment and the corresponding downlink forwarding equipment according to the information such as the position, the performance parameters and the like of the terminal equipment, the base station and the plurality of forwarding equipment. The uplink forwarding equipment and the downlink forwarding equipment are decoupled, and the uplink signals and the downlink signals of the terminal are forwarded by different forwarding equipment, so that the optimal forwarding equipment is respectively adapted to the uplink signals and the downlink signals under the condition that the uplink transmission performance and the downlink transmission performance are different, and the transmission performance of the uplink and the downlink is improved.
In one design, as shown in fig. 6, the method for controlling signal forwarding according to the embodiment of the present application, before the step S201, further includes S401-S402, or S401-S403:
S401, determining the distance between the terminal equipment and each of the plurality of forwarding equipment and the distance between the base station and each of the plurality of forwarding equipment based on the positions of the terminal equipment and the plurality of forwarding equipment.
Alternatively, the base station or other device may determine a distance between the terminal device and each of the plurality of forwarding devices, respectively, and a distance between the base station and each of the plurality of forwarding devices, respectively, based on the locations of the terminal device and the plurality of forwarding devices.
For example, the number of the plurality of forwarding devices is 4, and the forwarding devices 1,2,3, and 4 are respectively assumed. The distance between the terminal device and the forwarding device 1 is 50 meters, the distance between the terminal device and the forwarding device 2 is 100 meters, the distance between the terminal device and the forwarding device 3 is 150 meters, and the distance between the terminal device and the forwarding device 4 is 200 meters. The distance between the base station and the forwarding device 1 is 50 meters, the distance between the base station and the forwarding device 2 is 100 meters, the distance between the base station and the forwarding device 3 is 150 meters, and the distance between the base station and the forwarding device 4 is 200 meters.
S402, determining a first forwarding device from forwarding devices with a distance between the forwarding devices and the terminal device being smaller than a first value.
Alternatively, the base station or other device may determine the first forwarding device from among the forwarding devices having a distance from the terminal device less than the first value, based on the distance between the terminal device and each of the plurality of forwarding devices, respectively. Further, if the number of forwarding devices smaller than the first value is plural, the first forwarding device may be determined randomly from the forwarding devices smaller than the first value, the device with the smallest distance from the terminal device among the forwarding devices smaller than the first value may be determined as the first forwarding device, or the plural forwarding devices smaller than the first value may be determined as the first forwarding device.
By way of example, it is assumed that the first value may be 150 meters. Then forwarding devices smaller than 150 meters have forwarding device 1 and forwarding device 2, and both forwarding device 1 and forwarding device 2 may be first forwarding devices.
S403, determining a second forwarding device from the forwarding devices with the distance between the plurality of forwarding devices and the base station being smaller than a second value.
Alternatively, the base station or other device may determine the second forwarding device from among the forwarding devices having a distance from the terminal device smaller than the second value, according to the distance between the base station and each of the plurality of forwarding devices, respectively. Further, if the number of forwarding devices smaller than the second value is plural, the second forwarding device may be determined randomly from the forwarding devices smaller than the second value, or a device with the smallest distance from the base station among the forwarding devices smaller than the second value may be determined as the second forwarding device, or plural forwarding devices smaller than the second value may be determined as the second forwarding device.
Illustratively, it is assumed that the second value may be 150 meters. Then forwarding devices smaller than 150 meters have forwarding device 1 and forwarding device 2, and both forwarding device 1 and forwarding device 2 may be second forwarding devices. The application can determine the forwarding equipment with small distance to the terminal equipment as the uplink forwarding equipment and the forwarding equipment with small distance to the base station as the downlink forwarding equipment. This is because, when a repeater apparatus receives a signal, the closer the distance from the apparatus transmitting the signal is, the greater the intensity of an incident signal is, and the higher the quality of the repeated signal is. Therefore, the uplink incident signal strength and the downlink incident signal strength of the forwarding equipment can be improved, the quality of the forwarding signals is further improved, and the uplink and downlink transmission performance of the terminal equipment is improved.
In one design, as shown in fig. 7, the method for controlling signal forwarding according to the embodiment of the present application further includes S501, S502, S503, or S504 before the step S201:
S501, determining a first forwarding device from forwarding devices with the number of access terminal devices smaller than a fifth value in a plurality of forwarding devices when the uplink minimum transmission rate is larger than a third value and/or the uplink maximum transmission delay is smaller than or equal to a fourth value.
Alternatively, 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 devices may determine the first forwarding device from the forwarding devices, where the number of access terminal devices in the forwarding devices is less than the fifth value. Further, if the number of forwarding devices of the access terminal device smaller than the fifth value is plural, the first forwarding device may be determined randomly from the forwarding devices of the access terminal device smaller than the fifth value, the device of the access terminal device having the smallest number may be determined as the first forwarding device, and the plural forwarding devices of the access terminal device smaller than the fifth value may be determined as the first forwarding device.
Illustratively, the third value may be any reasonable value of 8bps, 9bps, etc., and the fourth value may be any reasonable value of 1ms, 2 ms. The fifth value may be any reasonable value such as 20.
It should be noted that the minimum transmission rate and the maximum transmission delay of the terminal device may be used to reflect the minimum transmission performance requirement 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 equipment are. The smaller the minimum transmission rate and the larger the maximum transmission delay, the lower the transmission performance requirements of the terminal equipment are. The number of forwarding device access terminal devices may reflect the load factor of the forwarding device, and the more the number of forwarding device access terminal devices, the greater the load factor, the fewer forwarding resources may be configured for the target forwarding device, and the worse the transmission performance of the forwarding device, and vice versa.
S502, determining a first forwarding device from forwarding devices with a distance between the forwarding devices and the terminal device smaller than the first value under the condition that the uplink minimum transmission rate is smaller than or equal to the third value and/or the uplink maximum transmission delay is larger than the fourth value.

If the number of forwarding devices smaller than the first value is plural, the first forwarding device may be determined randomly from the forwarding devices smaller than the first value, a device with the smallest distance from the terminal device among the forwarding devices smaller than the first value may be determined as the first forwarding device, and a plurality of forwarding devices with the distance from the terminal device smaller than the first value may be determined as the first forwarding device.
S503, determining a second forwarding device from forwarding devices with the number of access terminal devices smaller than the fifth value in the plurality of forwarding devices when the downlink minimum transmission rate is larger than the third value and/or the downlink maximum transmission delay is smaller than or equal to the fourth value.
Optionally, the base station or other device may determine whether the downlink 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. In the case that 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, the base station or other device may determine the second forwarding device from the forwarding devices, of the plurality of forwarding devices, for which the number of access terminal devices is less than the fifth value. Further, if the number of forwarding devices of the access terminal device smaller than the fifth value is plural, the second forwarding device may be determined randomly from the forwarding devices of the access terminal device smaller than the fifth value, the device of the access terminal device having the smallest number may be determined as the second forwarding device, and the plural forwarding devices of the access terminal device smaller than the fifth value may be determined as the second forwarding device.
S504, determining a second forwarding device from forwarding devices with a distance between the forwarding devices and the terminal device smaller than the second value under the condition that the downlink minimum transmission rate is smaller than or equal to the third value and/or the downlink maximum transmission delay is larger than the fourth value.
Optionally, in the case that 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 forwarding devices, where a distance between the plurality of forwarding devices and the terminal device is less than the second value. Further, if the number of forwarding devices smaller than the second value is plural, the second forwarding device may be determined randomly from the forwarding devices smaller than the second value, or a device with the smallest distance from the base station among the forwarding devices smaller than the second value may be determined as the second forwarding device, or plural forwarding devices smaller than the second value may be determined as the second forwarding device.
The application can select the forwarding equipment with less access terminal equipment for service transmission of the terminal equipment under the condition of high transmission performance requirement of the terminal equipment, so that more forwarding resources can be configured for the forwarding equipment, and the transmission performance is improved. And selecting forwarding equipment which is closer to the terminal under the condition that the transmission performance requirement of the terminal equipment is not high, so that the signal transmission path loss is reduced, the signal receiving strength is improved, and the transmission performance of the terminal equipment is further improved.
