Background

Currently, when a User Equipment (UE) is located outside a network coverage area or in an edge weak signal area of a network device, the UE needs to implement data transmission with the network device by means of a relay device. Typically, the UE randomly selects one relay device for data transmission with the network device.

Resulting in poor efficiency of data transmission between the UE and the network device.

In the embodiment of the present application, the network device may correspond to at least one relay device cluster. For example, one base station corresponds to at least one relay device cluster. In other words, the communication system may comprise a UE, a network device and at least one relay device cluster.

In an embodiment of the present application, the at least one relay device cluster may include relay devices within a preset distance around the network device. It can be appreciated that the relay devices within a preset distance around the network device can be divided into at least one relay device cluster according to the location of the relay devices.

In an embodiment of the present application, each of the at least one relay device cluster may include at least one relay device.

In the embodiment of the present application, the above-mentioned relay device may include, but is not limited to: UE, cell phone, tablet, wearable device.

The data transmission method, the device, the relay device, the network device and the medium provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

The data transmission method, the device, the relay equipment, the network equipment and the medium provided by the embodiment of the application can be applied to the scene that the UE performs data transmission with the network equipment through the relay equipment cluster.

Currently, the third generation partnership project (3rd Generation Partnership Project,3GPP) R16 version introduces a sidestream communication (NR Sidelink) technology between devices, mainly focuses on road security services related to information exchange (vehicle to everything, V2X) between vehicles to the outside, and implements broadcast, multicast and unicast communication between terminals in network coverage and under coverage outside scenes. On this basis, in order to further extend coverage of the Network and NR sidelink, improve power efficiency, and support wider applications and services, the 3GPP introduced a UE communication (U2 NRelay) Relay technology in release R17, as shown in fig. 2, when the link quality between the remote UE21 and the Network device 22 is degraded, the remote UE11 may select an appropriate Relay device 23, and ensure continuity of services through the U2N Relay technology.

Generally, when a UE selects a relay device to deal with a communication service problem, a device whose signal quality satisfies a threshold is selected randomly for data transmission. Without determining whether the currently selected relay device is the best or most suitable relay device. Therefore, if the signal quality of the selected relay device is not good enough, abnormal data transmission may be caused, such as call failure, slow surfing, slow downloading, or ping-pong behavior of switching the relay device back and forth, which may result in poor data transmission efficiency between the UE and the network device.

In the data transmission method, the device, the relay device, the network device and the medium provided by the embodiment of the application, under the condition that the number of the data packets accumulated in the first relay device exceeds the first threshold value, the data packets can be transmitted to the network device or the target UE together through the cooperative work of the plurality of relay devices in the first relay device cluster where the first relay device is located. Therefore, the rate of the cooperative transmission of the data packets by the relay equipment can be improved, and the delay of the data transmission is reduced, so that the efficiency of the data transmission between the UE and the network equipment is improved.

The execution body of the data transmission method provided in the embodiment of the application may be a data transmission device. The data transmission means may be, for example, a communication device, such as a relay device or a network device, or may be a component of the communication device, such as an integrated circuit or a chip.

An embodiment of the present application provides a data transmission method, and fig. 3 shows a flowchart of the data transmission method provided in the embodiment of the present application, where the method may be performed by a first relay device, that is, the data transmission method provided in the embodiment of the present application will be exemplarily described below by taking the first relay device as an example.

As shown in fig. 3, the data transmission method provided in the embodiment of the present application may include the following step 201.

In step 201, if the number of the first data packets exceeds a first threshold, the first relay device sends a second data packet to the target device, and sends a third data packet to the target device through the second relay device.

The first relay device is a relay device in a first relay device cluster, the first relay device cluster comprises N relay devices, the target device comprises network devices or target UE corresponding to the first relay device cluster, and N is an integer greater than 1; the first data packet is a data packet piled up in the first relay device, and comprises a second data packet and a third data packet; the second relay device is a relay device in the first relay device cluster, and the second relay device is different from the first relay device.

In some embodiments of the present application, the target UE may be a device that needs to perform data transmission; the network device may be a device that provides network services for the target UE.

In some embodiments of the present application, the second relay device is at least one of the other relay devices in the N relay devices in the first relay device cluster, except for the first relay device.

In an embodiment of the present application, the first data packet may include a data packet received by the first relay device.

In some embodiments of the present application, in a process of data transmission between a target UE and a network device through a first relay device, the first relay device may forward, to a second relay device, a stacked data packet that is not timely sent to the target device, so that the first relay device and the second relay device may cooperatively send the data packet to the target device.

It is to be appreciated that the target UE can be a device that is at or outside of a communication range of the network device. In this way, the target UE and the network device may perform data transmission through the first relay device.

In some embodiments of the present application, the network device corresponds to at least one relay device cluster, and the first relay device cluster is one of the at least one relay device cluster.

In some embodiments of the present application, the "the number of first data packets exceeds the first threshold" may indicate that: the number of the first data packets is larger, so that the process of sending the first data packets to the target device by the first relay device is longer. Therefore, the second relay device and the first relay device need to cooperate to send the first data packet to the target device together, so as to improve the transmission rate of the data packet.

In some embodiments of the present application, when the number of data packets received by the first relay device is greater, the first relay device may distribute a portion of the data packets in the first data packets to at least one relay device in other relay devices except the first relay device in the first relay device cluster, and cooperatively transmit the first data packets through the at least one relay device, so as to improve a transmission rate of the first data packets.

It may be appreciated that the first relay device may first establish a connection with at least one relay device in other relay devices in the first relay device cluster except for the first relay device, and then send a third data packet in the first data packet to the at least one relay device; the at least one relay device may send the third data packet to the target device after receiving the third data packet. Thus, through cooperative transmission of a plurality of relay devices in the first relay device cluster, the data transmission rate between the target UE and the network device can be improved.

In some embodiments of the present application, the first threshold may be default to the first relay device, or may be set by a user. The embodiments of the present application are not particularly limited.

In some embodiments of the present application, after the first relay device sends the second data packet to the target device and sends the third data packet to the target device through the second relay device, the target device may send feedback information corresponding to the second data packet to the first relay device and send feedback information corresponding to the third data packet to the second relay device after receiving the second data packet and the third data packet; then, the second relay device may send the received feedback information to the first relay device, and after being comprehensively processed by the first relay device, send the feedback information to the sending device of the data packet, so that the sending device of the data packet may determine whether the data packet is successfully transmitted.

In some embodiments of the present application, after receiving the second data packet and the third data packet, the target device may decode and reorder the second data packet and the third data packet to confirm whether the transmission of the data packet is completed. It may be appreciated that if the data packet is not transmitted within a certain time, the target device may determine to discard the data packet and send corresponding feedback information to the first relay device and the second relay device.

In some embodiments of the present application, after the second relay device sends the received feedback information to the first relay device, the first relay device may confirm a transmission status, such as a transmission success or a transmission failure, of each data packet. Then, the first relay device may perform comprehensive analysis processing on the received multiple feedback information to generate new feedback information, and send the new feedback information to the sending device of the data packet, so that the sending device of the data packet may determine the transmission state of the data packet, so that the sending device of the data packet may perform response processing according to the transmission state of the data packet, so that the retransmitted data packet may be better transmitted.

For example, the sending device of the data packet may initiate a retransmission mechanism or a discard mechanism after the data packet transmission fails, so that the retransmitted data packet may be better transmitted.

According to the data transmission method, under the condition that the number of data packets accumulated in the first relay device exceeds the first threshold, the data packets can be transmitted to the network device or the target UE together through the cooperation of the plurality of relay devices in the first relay device cluster where the first relay device is located. Therefore, the rate of the cooperative transmission of the data packets by the relay equipment can be improved, and the delay of the data transmission is reduced, so that the efficiency of the data transmission between the UE and the network equipment is improved.

In some embodiments of the present application, in a case where the target device includes the target UE, before the step 201, the data transmission method provided in the embodiments of the present application may further include the following step 202.

Step 202, the first relay device receives a data packet sent by the network device.

The first data packet may further include a data packet received by the first relay device and sent by the network device.

It may be appreciated that in the case where the target device includes the target UE, the network device may send the data packet to the target UE through the first relay device. That is, the data packet accumulated in the first relay device may be a data packet transmitted to the target UE by the network device or other devices.

In some embodiments of the present application, in a case where the target device includes a network device, before the step 201, the data transmission method provided in the embodiments of the present application may further include the following step 203.

Step 203, the first relay device receives the data packet sent by the target UE.

The first data packet may further include a data packet sent by the target UE and received by the first relay device.

It will be appreciated that in the case where the target device includes a network device, the target UE may send a data packet to the network device through the first relay device. That is, the data packet accumulated in the first relay device may be a data packet transmitted to the network device by the target UE or other devices.

In one embodiment, for a scenario in which the target device includes the target UE, the first relay device may receive the data packets sent by the network device, send the second data packets to the target UE if the number of the first data packets sent by the network device exceeds the first threshold, and send the third data packets to the target UE through the second relay device.

Illustratively, as shown in fig. 4, the relay device cluster includes 6 relay devices, namely, a relay device 41, a relay device 42, a relay device 43, a relay device 44, a relay device 45, and a relay device 46. It is assumed that the relay device 41, the relay device 42, and the relay device 43 constitute the relay device cluster 1; the relay device 44, the relay device 45, and the relay device 46 constitute the relay device cluster 2. As shown in fig. 4, assuming that the transmitting device of the data packet is the network device 47 and the target device is the mobile phone 40, the relay device 45 may transmit the third data packet to the relay device 44 when the number of received data packets from the network device 47 exceeds the first threshold after receiving the data packet transmitted by the network device 47. So that the relay device 45 can send the third data packet to the handset 50 at the same time as the second data packet is sent to the handset 50. Thus, the transmission efficiency of the data packet between the mobile phone 50 and the network device 47 can be improved.

In another embodiment, for a scenario in which the target device includes a network device, the first relay device may receive a data packet sent by the target UE, send a second data packet to the network device if the number of first data packets sent by the target UE exceeds a first threshold, and send a third data packet to the network device through the second relay device.

Illustratively, as shown in fig. 5, the relay device cluster includes 6 relay devices, namely, a relay device 51, a relay device 52, a relay device 53, a relay device 54, a relay device 55, and a relay device 56. Suppose that the relay device 51, the relay device 52, and the relay device 53 constitute the relay device cluster 1; the relay device 54, the relay device 55, and the relay device 56 constitute the relay device cluster 2. As shown in fig. 5, assuming that the transmitting device of the data packet is the mobile phone 50, the target device is the network device 57, the relay device 54 may transmit the third data packet to the relay device 55 when the number of received data packets from the mobile phone 50 exceeds the first threshold after receiving the data packet transmitted by the mobile phone 50. So that relay device 54 may send the third data packet to network device 57 at the same time as the second data packet to network device 57. Thus, the transmission efficiency of the data packet between the mobile phone 50 and the network device 57 can be improved.

In this way, the target UE and the network device may cooperate with each other through a plurality of relay devices in the relay device cluster to perform data transmission. Therefore, the data packet transmission rate through the relay equipment can be improved, and the data transmission delay is reduced, so that the data transmission efficiency between the UE and the network equipment is improved.

In some embodiments of the present application, as shown in fig. 6 in conjunction with fig. 3, the step 201 may include a step 201a described below.

In step 201a, when the rate at which the first relay device sends data packets to the target device is lower than the second threshold and the number of the first data packets exceeds the first threshold, the first relay device sends second data packets to the target device, and sends third data packets to the target device through the second relay device.

In some embodiments of the present application, the "the data transmission rate at which the first relay device transmits the data packet to the target device is lower than the second threshold" may indicate that: the current data transmission rate of the first relay device for transmitting the data packet to the target device is slow, which results in a longer process of transmitting the data packet to the target device by the first relay device. Therefore, the second relay device needs to work cooperatively with the first relay device to send the first data packet to the target device together, so that the transmission rate of the data packet is improved.

It may be appreciated that, if the data transmission rate of the data packets sent by the first relay device to the target device is lower than the second threshold value and the number of the first data packets exceeds the first threshold value, there may be stacked data packets to be sent in the first relay device, which results in a longer delay in sending the newly received data packets. Therefore, the first relay device can establish connection with the second relay device when the transmission rate of the current data packet is low and the number of accumulated data packets to be transmitted is large, and send the second data packet to the target device and simultaneously send the third data packet to the target device through the second relay device, so that the transmission rate of the data packet is improved.

Illustratively, the first threshold is 50 and the second threshold is 20 kb. When the data transmission rate of the first relay device for transmitting the data packets to the target device is lower than 20kb and the number of the first data packets exceeds 50, the first relay device may establish a connection with the second relay device, and transmit the second data packets to the target device and simultaneously transmit the third data packets to the target device through the second relay device, so as to improve the transmission rate of the data packets.

In some embodiments of the present application, the second threshold may be default to the first relay device, and may also be set by a user. The embodiments of the present application are not particularly limited.

Therefore, the first relay device can cooperatively work through other relay devices in the first relay device cluster to jointly transmit the data packet to the target device under the condition that the data transmission rate of the data packet transmitted by the first relay device to the target device is low and the number of the first data packets is large. Therefore, the data packet transmission rate through the relay equipment can be improved, and the data transmission delay is reduced, so that the data transmission efficiency between the UE and the network equipment is improved.

The embodiment of the present application further provides a data transmission method, and fig. 7 shows a flowchart of the data transmission method provided in the embodiment of the present application, where the method may be performed by a network device, that is, the data transmission method provided in the embodiment of the present application is exemplified by the network device.

As shown in fig. 7, the data transmission method provided in the embodiment of the present application may include the following steps 301 to 303.

Step 301, the network device receives cluster information of at least one relay device cluster from a third relay device.

Wherein the at least one relay device cluster corresponds to a network device.

In some embodiments of the present application, the third relay device may be any relay device in any relay device cluster in at least one relay device cluster corresponding to the network device.

In some embodiments of the present application, the third relay device may be the same as or different from the first relay device; the third relay device may be the same as or different from the second relay device.

In some embodiments of the present application, each network device may determine a relay device within a preset distance around the network device as at least one relay device cluster corresponding to the network device. It is understood that there may be overlapping ranges of relay device clusters corresponding to different network devices.

Illustratively, as shown in fig. 8, the range of the relay device cluster corresponding to the network device 81 is an area 82; the range of the relay device cluster corresponding to the network device 83 is an area 84. The area 85 is a range of the relay device cluster corresponding to the network device 81, and is a range of the relay device cluster corresponding to the network device 83.

In some embodiments of the present application, the cluster information of the relay device cluster may include at least one of the following: capability information of the relay device cluster, signal information of the relay device cluster, and information of UEs having access to the relay device cluster.

In some embodiments of the present application, the above-described capability information may be used to indicate at least one of: whether the relay device cluster supports a network transmitting the fourth data packet or not, and whether the relay device cluster supports a frequency band transmitting the fourth data packet or not.

The fourth data packet is a data packet transmitted between the target UE and the network device.

In some embodiments of the present application, the network transmitting the fourth data packet may include, but is not limited to: a long term evolution (Long Term Evolution, LTE) network, a New air interface (NR) network, a long term evolution voice bearer (Voice over Long Term Evolution, VOLTE) network, a high definition video telephony (Video over Long Term Evolution, VILTE) network, a New air interface bearer voice (Voice over New Radio, VONR) network, a wireless fidelity based voice services (Voice over WIreless Fidelity, VOWIFI) network.

In some embodiments of the present application, the network device may determine, according to the capability information of each relay device in the relay device cluster, whether the relay device cluster supports a network transmitting the fourth data packet.

Illustratively, each relay device in the relay device cluster supports an LTE network may then represent a wireless network technology that the relay device cluster may support 4G.

Illustratively, each relay device in the relay device cluster supports an NR network, which may then represent a wireless network that the relay device cluster may support 5G.

For example, each relay device in the relay device cluster supports a VOLTE network, which may indicate that the relay device cluster may support voice calls in a 4G network.

For example, each relay device in the relay device cluster supports a VILTE network may indicate that the relay device cluster may support video calls under a 4G network.

Illustratively, each relay device in the relay device cluster supports a VONR network, which may indicate that the relay device cluster may support a video call under a 5G network.

For example, each relay device in the relay device cluster supports a VOWIFI network, which may indicate that the relay device cluster may support making and receiving voice or video calls while using the mobile internet.

In some embodiments of the present application, the frequency band for transmitting the fourth data packet may be a transmission frequency band used when the relay device transmits the data packet for the target UE and the network device.

For example, if the transmission frequency band adopted when the target UE and the network device transmit the data packet of the voice call is 3MHz-30MHz, the relay device cluster should support transmitting the data packet of the 3MHz-30MHz frequency band.

In some embodiments of the present application, the signal information includes at least one of: reference signal received power (Reference Signal Receiving Power, RSRP), reference signal received quality (Reference Signal Receiving Quality, RSRQ) and signal-to-noise ratio (Signal to Interference plus Noise Ratio, SINR) of the relay device cluster;

In some embodiments of the present application, the signal information may indicate a quality of a useful signal received by the relay device cluster.

Illustratively, the RSRP may indicate the strength of the signal received by the relay device cluster.

For example, the RSRQ may indicate the quality of the signal received by the relay device cluster.

Illustratively, the SINR may indicate a ratio of the strength of the useful signal received by the cluster of relay devices to the strength of the received interfering signal (noise and interference).

In some embodiments of the present application, the above information of the UE that has accessed the relay device cluster may indicate a load condition of the UE that has accessed the relay device cluster. It can be appreciated that the more UEs the relay device cluster has access to, the higher its load.

In some embodiments of the present application, the third relay device may obtain the capability information and the signal information of the different relay device clusters and the information of the UE that has accessed the relay device cluster, that is, the cluster information of the different relay device clusters, by obtaining the capability information and the signal information of each relay device in the different relay device clusters and the information of the UE that has accessed the relay device clusters.

For example, the third relay device may send query signaling to each relay device in different relay device clusters in the relay device cluster to obtain capability information, signal information, and information of UEs that have accessed the relay device in the different relay device clusters in the relay device cluster.

It should be noted that, the third relay device may query capability information, signal information of other relay devices in the relay device cluster and information of UEs that have accessed the relay device cluster through an inter-device direct communication (Proximity Communication, PC 5) interface.

In some embodiments of the present application, the step 301 may include a step 301a described below.

Step 301a, the network device periodically receives cluster information of at least one relay device cluster from a third relay device.

In some embodiments of the present application, the network device may periodically obtain, through the third relay device, capability information, signal information of each relay device in at least one relay device cluster, and information of UEs that have accessed the relay device cluster according to a preset period.

Thus, the network device can periodically acquire the cluster information of at least one relay device cluster, so that the reliability of the cluster information used by the network device is ensured.

It can be understood that each relay device in the relay device cluster can acquire capability information, signal information and information of UEs that have accessed the relay device cluster of other relay devices, so that each relay device can acquire cluster information of the relay device cluster and send the cluster information to the network device, and the network device can flexibly acquire the cluster information of the relay device cluster.

In some embodiments of the present application, the third relay device may store and send the acquired capability information, signal information and information of the UE that has accessed the relay device cluster according to the relay device cluster.

For example, the third relay device may store the cluster information of each relay device cluster as a list, and each element in the list may correspond to capability information, signal information of one relay device in the relay device cluster, and information of UEs having accessed the relay device cluster.

Step 302, the network device determines a first relay device cluster matched with the network state of the network device from at least one relay device cluster based on the cluster information of each relay device cluster.

In some embodiments of the present application, after receiving the cluster information of each relay device cluster in at least one relay device cluster sent by the third relay device, the network device may parse the cluster information of each relay device cluster to obtain capability information, signal information of each relay device cluster in each relay device cluster and information of UEs having accessed the relay device cluster, so that the network device may determine a first relay device cluster from the relay device clusters, where each relay device in the first relay device cluster matches with a network state of the network device.

In some embodiments of the present application, the "first relay device cluster matching the network status of the network device" in step 302 may include:

the capability information and the signal information of the first relay equipment cluster are matched with the network state of the network equipment;

the number of target UEs of the first relay device cluster, indicated by the information of the UEs of the first relay device cluster, that have accessed the relay device cluster, is smaller than a third threshold.

In some embodiments of the present application, the network status of the network device may include a network load of the network device and a quality of a network signal of the network device.

In some embodiments of the present application, the "capability information and signal information of the first relay device cluster, which match the network status of the network device" may indicate: the information of the technology supported by the first relay device cluster indicated by the capability information of the first relay device cluster is matched with the network of the network device, and the quality of the useful signal received by the first relay device cluster indicated by the signal information of the first relay device cluster is matched with the quality of the network signal of the network device. In other words, the technology supported by the first relay device cluster is a technology supported by the network of the network device; and the sum of the quality of the network signal of the network device and the quality of the useful signal received by the first relay device cluster needs to be greater than a quality threshold value, so that the data transmission with better signal quality can be successfully performed between the third relay device and the network device.

In some embodiments of the present application, the "the number of target UEs of the accessed relay device cluster indicated by the information of UEs of the first relay device cluster that have accessed the relay device cluster is smaller than the third threshold" may indicate that: the network device needs to select a relay device cluster with a smaller number of target UEs accessing the relay device cluster, so that the access load of the relay device cluster is in a lower state, thereby avoiding the congestion of data packets when transmitting data.

It may be appreciated that the network device may determine, as the first relay device cluster, a relay device cluster in which capability information and signal information of each relay device in the relay device cluster are matched with a network state of the network device, and the number of target terminals of the accessed relay device cluster indicated by information of UEs that have accessed the relay device cluster is smaller than a third threshold.

In some embodiments of the present application, the third threshold may be set by a developer, or may be default for the network device. The embodiments of the present application are not particularly limited.

In this way, since the network device can determine the relay device cluster matching the network state of the network device according to the capability information, the signal information and the information of the UE having accessed the relay device cluster. Therefore, the determined relay equipment cluster can better and faster transmit the data packet between the target UE and the network equipment, thereby improving the efficiency of data transmission between the UE and the base station.

Step 303, the network device sends cluster information of the first relay device cluster to the target UE through the third relay device.

The first relay device cluster comprises N relay devices, cluster information of the first relay device cluster is used for indicating the target UE to access the first relay devices in the first relay device cluster, and N is an integer greater than 1.

In some embodiments of the present application, after receiving the cluster information of the first relay device cluster sent by the network device, the third relay device may send the cluster information of the first relay device cluster to the target UE, and after receiving the cluster information of the first relay device cluster, the target UE may establish a connection with one relay device in the first relay device cluster. The target UE can perform data transmission with the network equipment through at least one relay equipment in the first relay equipment cluster.

According to the data transmission method, as the network equipment can determine the relay equipment cluster matched with the network state of the network equipment in the at least one corresponding relay equipment cluster, the target UE and the network equipment can transmit data through the relay equipment cluster, so that the target UE and the network equipment can be prevented from transmitting data through the relay equipment cluster with poor signal quality or low transmission rate, and the efficiency of data transmission between the UE and the network equipment is improved.

The embodiment of the present application further provides a data transmission method, and fig. 9 shows a flowchart of the data transmission method provided in the embodiment of the present application, where the method may be performed by a target UE, that is, the data transmission method provided in the embodiment of the present application will be exemplarily described below by taking the target UE as an example.

As shown in fig. 9, the data transmission method provided in the embodiment of the present application may include the following steps 401 to 403.

Step 401, the target UE accesses a third relay device in the second relay device cluster.

The third relay device may be any relay device in the second relay device cluster.

In some embodiments of the present application, the second relay device cluster may be one relay device cluster in at least one first relay device cluster corresponding to a network device, where the second relay device cluster may include M relay devices, and M is an integer greater than 1.

In some embodiments of the present application, the second relay device cluster may be the same as or different from the first relay device cluster.

In some embodiments of the present application, the target UE may randomly select one relay device for access when the target UE is out of coverage of the network device or in a weak signal area at an edge of coverage of the network device, that is, a third relay device in the second relay device cluster.

For example, the target UE may send an access query signaling to the relay device cluster corresponding to the network device, and randomly select any relay device in any relay device cluster around the target UE for access.

It can be understood that, when the target UE is out of coverage of the network device or is in a weak signal area at the edge of coverage of the network device, the signal quality is poor when the target UE performs data transmission with the network device, so that the target UE may perform data transmission with the network device through the relay device.

In some embodiments of the present application, the target UE may access the third relay device through a PC5 interface.

Step 402, the target UE receives cluster information of the first relay device cluster from the third relay device.

The first relay device cluster is a relay device cluster matched with a network state of network devices in the relay device cluster, and the network devices correspond to the relay device cluster.

Step 403, the target UE accesses the first relay device in the first relay device cluster.

In some embodiments of the present application, after determining a first relay device cluster that matches a network state of the network device, the network device may send cluster information of the first relay device cluster to the target UE through the third relay device, so that the target UE may select the first relay device from the first relay device cluster for access. In other words, the target UE may switch the accessed relay device from the third relay device in the second relay device cluster to the first relay device in the first relay device cluster.

It can be appreciated that if the first relay device cluster is the same as the second relay device cluster, the target UE does not need to switch the accessed relay devices.

In some embodiments of the present application, the target UE may randomly select one relay device from the first relay device cluster as the first relay device for access, or may select one relay device with better signal quality from the first relay device cluster as the first relay device for access. The embodiments of the present application are not particularly limited.

It should be noted that, for a detailed description of the first relay device cluster being a relay device cluster matching with the network state of the network device in the relay device cluster, reference may be made to the detailed descriptions in the above steps 301 to 303. To avoid repetition, no further description is provided here.

Therefore, the target UE can switch the accessed relay equipment into one relay equipment in the relay equipment cluster according to the relay equipment cluster which is determined by the network equipment and is matched with the network state, so that the best relay equipment cluster is ensured to be adopted when the target UE performs data transmission with the network equipment, and the efficiency of data transmission between the UE and the network equipment can be improved through the relay equipment cluster.

The above method embodiments, or various possible implementation manners in the method embodiments, may be executed separately, or may be executed in any two or more combinations, which may be specifically determined according to actual use requirements, and this embodiment of the application is not limited.

The data transmission method provided in the embodiment of the present application is exemplarily described below with specific examples.

Example 1: taking a sending device of a data packet as a target UE, and taking a target device as a network device as an example. As shown in fig. 10, the data transmission method may include steps 501 to 509 described below.

Step 501, the target UE randomly accesses a third relay device in the second relay device cluster.

In some embodiments of the present application, the second relay device cluster is from a relay device cluster, where the relay device cluster includes at least one relay device cluster, and each relay device cluster includes at least one relay device.

Step 502, the third relay device queries cluster information of each relay device cluster in at least one relay device cluster corresponding to the network device.

In some embodiments of the present application, the third relay device may obtain the cluster information of each relay device cluster by querying capability information, signal information of each relay device in each relay device cluster, and information of UEs that have accessed the relay device cluster.

In step 503, the third relay device sends cluster information of each relay device cluster to the network device.

Step 504, the network device receives cluster information of each relay device cluster in the at least one relay device cluster from the third relay device, and determines a first relay device cluster matched with the network state of the network device from the relay device clusters based on the cluster information of each relay device cluster.

Step 505, the network device sends cluster information of the first relay device cluster to the third relay device.

In step 506, the third relay device receives the cluster information of the first relay device cluster from the network device, and sends the cluster information of the first relay device cluster to the target UE.

In step 507, the target UE receives cluster information of the first relay device cluster from the third relay device.

Step 508, the target UE accesses the first relay device in the first relay device cluster, and the first relay device sends the data packet to the network device.

Step 509, the first relay device receives the data packets sent by the target UE, and sends the second data packets to the network device and sends the third data packets to the network device through the second relay device when the number of the first data packets sent by the target UE exceeds the first threshold.

It is understood that the first data packet includes a second data packet and a third data packet, and the second relay device is at least one of the other relay devices except the first relay device.

In this way, when the number of data packets stacked in the first relay device exceeds the first threshold, the data packets can be transmitted to the network device or the target UE together by the plurality of relay devices in the first relay device cluster where the first relay device is located. Therefore, the rate of the cooperative transmission of the data packets by the relay equipment can be improved, and the delay of the data transmission is reduced, so that the efficiency of the data transmission between the UE and the network equipment is improved.

Example 2: taking a sending device of a data packet as a network device, and taking a target device as a target UE as an example. As shown in fig. 11, the data transmission method may include steps 601 and 602 described below.

In step 601, the network device sends a data packet to the target UE through the first relay device.

In step 602, the first relay device receives the data packets sent by the network device, and sends the second data packets to the target UE and sends the third data packets to the target UE through the second relay device when the number of the first data packets sent by the network device exceeds the first threshold.

In this way, the network device can determine the relay device cluster matched with the network state of the network device in at least one corresponding relay device cluster, so that the target UE and the network device can perform data transmission through the relay device cluster, thereby avoiding the data transmission between the target UE and the network device through the relay device cluster with poor signal quality or low transmission rate, and improving the efficiency of data transmission between the UE and the network device.
