The path loss, or Propagation Loss (PL), refers to the loss caused by the propagation of radio waves in space, and is caused by the radiation spread of the transmitted power and the propagation characteristics of the channel, reflecting the variation of the mean value of the received signal power in the macroscopic range.

Throughput (Throughput) refers to the amount of data (measured in bits, bytes, packets, etc.) successfully transmitted per unit of time to a network, device, port, virtual circuit, or other facility.
The following describes a data transmission method provided by an embodiment of the present invention, with reference to the communication system shown in fig. 1 and taking an electronic device as a server 1 as an example.
As shown in fig. 2, the data transmission method includes the following steps S11-S14:
s11, the server 1 receives the sensing information reported by each wireless node in at least one wireless node currently served in a period. The perception information comprises identification codes and network parameters reported by each terminal in at least one terminal in a coverage range, and each identification code corresponds to one wireless node.
In a practical manner, the server 1 only obtains the sensing information reported by each wireless node currently served, and different servers 1 may also perform communication. When the terminal reports the network parameters, the terminal only reports the perception information to the wireless node which serves the terminal currently.
For example, the terminal may acquire the network parameter periodically, for example, the terminal acquires the network parameter once every 1 Transmission Time Interval (TTI). In order to Report the network parameters to the wireless node, the terminal may encapsulate the network parameters in Channel State Information (CSI) Information and Report the CSI Information to the wireless node, or the terminal encapsulates the network parameters in Measurement Report (MR) data and reports the MR data to the wireless node, or the terminal directly reports the network parameters to the wireless node.
Illustratively, the network parameters reported by the terminal are shown in table 1.
TABLE 1
Figure BDA0003338657700000091
Wherein I represents the ith wireless node currently served by the server 1, UEin represents the nth terminal in the coverage of the ith wireless node, CSI-UEin represents the CSI information reported by the nth terminal in the coverage of the ith wireless node, I belongs to [1, I ], N belongs to [1, N ], I represents the total number of the wireless nodes currently served by the server 1, N represents the total number of terminals included in the coverage of the wireless node, and I, N, I and N are integers.
For example, the example is described in which the terminal encapsulates the network parameters in CSI information and reports the CSI information to the wireless node, and the sensing information reported by the wireless node is shown in table 2.
TABLE 2
Figure BDA0003338657700000101
S12, the server 1 determines theoretical bandwidth information supported by each wireless node according to the identification code reported by each wireless node.
S13, the server 1 determines the target bandwidth information of each wireless node in the next period according to the theoretical bandwidth information and the network parameter reported by each terminal in at least one terminal in the coverage area reported by each wireless node.
S14, the server 1 sends configuration information carrying the target bandwidth information to each wireless node. The configuration information is used for indicating each wireless node to provide service according to the target bandwidth information in the next period.
In the data transmission method provided by the invention, the server 1 receives the sensing information reported by each wireless node in at least one wireless node served in the current period, so that the theoretical bandwidth information supported by each wireless node can be determined according to the identification code reported by each wireless node; and determining the target bandwidth information of each wireless node in the next period according to the theoretical bandwidth information and the network parameters reported by each terminal in at least one terminal in the coverage range reported by each wireless node. Therefore, the configuration information carrying the target bandwidth information can be sent to each wireless node, so that each wireless node provides service according to the target bandwidth information in the next period. Therefore, the bandwidth of each wireless node currently served by the server 1 is changed according to the sensing information reported by each wireless node, so that the bandwidth utilization rate of each wireless node can be ensured, and the problem of how to improve the bandwidth utilization rate of the 6G network in the related technology is solved.
In an implementation manner, as shown in fig. 3 in conjunction with fig. 2, the above S12 can be specifically realized by the following S120-S122.
S120, the server 1 sends a bandwidth query request carrying the identification code reported by each wireless node to the network management system. The bandwidth query request is used for instructing the network management system to query theoretical bandwidth information corresponding to the identification code reported by each wireless node.
In an implementable manner, a network management system serves a plurality of servers 1, theoretical bandwidth information corresponding to identification codes of all wireless nodes served by each server 1 in the plurality of servers 1 is stored in the network management system, and when the server 1 needs to determine the theoretical bandwidth information supported by the wireless nodes, a bandwidth query request carrying the identification codes reported by each wireless node can be sent to the network management system. After receiving the bandwidth query request, the network management system queries theoretical bandwidth information corresponding to the identification code reported by each wireless node in the bandwidth query request.
Illustratively, it is explained that each wireless node has J bandwidth combinations, and theoretical bandwidth information corresponding to the identification code of each wireless node stored in the network management system is shown in table 3.
TABLE 3
Figure BDA0003338657700000111
Figure BDA0003338657700000121
Wherein, j is equal to [1 ],J]，
Figure BDA0003338657700000122
indicating the uplink bandwidth in the jth bandwidth combination supported by the ith wireless node,
Figure BDA0003338657700000123
and J are integers, and the downlink bandwidth in the jth bandwidth combination supported by the ith wireless node is represented.
Thus, when the server 1 needs to determine the theoretical bandwidth information supported by the wireless nodes, the bandwidth query request carrying the identification code reported by each wireless node can be sent to the network management system. After receiving the bandwidth query request, the network management system queries the theoretical bandwidth information corresponding to the identification code reported by each wireless node in the bandwidth query request in table 3, so that the theoretical bandwidth information corresponding to the identification code reported by each wireless node can be determined.
S121, the server 1 receives theoretical bandwidth information corresponding to the identification code reported by each wireless node and sent by the network management system.
S122, the server 1 determines theoretical bandwidth information supported by each wireless node according to the theoretical bandwidth information corresponding to the identification code reported by each wireless node.
For example, it is assumed that the server 1 currently serves only 2 wireless nodes, which are the wireless node with the identification code 1 and the wireless node with the identification code 2. The server 1 sends a bandwidth query request carrying identification codes (such as 1 and 2) reported by each wireless node to the network management system, the network management system queries theoretical bandwidth information corresponding to the identification code 1 and theoretical bandwidth information corresponding to the identification code 2 in a table 3 after receiving the bandwidth query request, and a query result is shown in a table 4.
TABLE 4
Figure BDA0003338657700000131
And then, the server 1 receives theoretical bandwidth information corresponding to the identification code reported by each wireless node and sent by the network management system. The server 1 determines theoretical bandwidth information supported by the wireless node with the identification code of 1, such as the theoretical bandwidth information corresponding to the identification code of 1 in table 4, and theoretical bandwidth information supported by the wireless node with the identification code of 2, such as the theoretical bandwidth information corresponding to the identification code of 2 in table 4, according to the theoretical bandwidth information corresponding to the identification code reported by each wireless node.
The above example is described by taking an example that the server 1 sends a bandwidth query request carrying an identification code reported by each wireless node to the network management system, and the server 1 determines theoretical bandwidth information supported by each wireless node according to theoretical bandwidth information corresponding to the identification code reported by each wireless node, which occurs in the network management system. In other examples, the server 1 locally stores theoretical bandwidth information corresponding to the identification codes of all the wireless nodes serving, so that when the server 1 needs to determine the theoretical bandwidth information supported by the wireless nodes, the theoretical bandwidth information corresponding to the identification code reported by each wireless node can be directly queried, thereby reducing the processing delay.
In an implementation manner, the theoretical bandwidth information includes at least one upstream bandwidth and at least one downstream bandwidth, and the target bandwidth information includes one upstream bandwidth and one downstream bandwidth, as shown in fig. 3 in conjunction with fig. 2, the above S13 can be specifically implemented by the following S130-S132.
S130, the server 1 determines at least one group of bandwidth configuration combination according to the theoretical bandwidth information. The bandwidth configuration combination comprises an uplink bandwidth and a downlink bandwidth corresponding to each wireless node.
In a practical manner, the bandwidth configuration combination includes an uplink bandwidth configuration combination and a downlink bandwidth configuration combination, and the total number of bandwidth combinations included in each wireless node currently served by the server 1 is the same. In this way, the server 1 recombines the upstream bandwidth and the downstream bandwidth in each bandwidth combination, so that at least one group of upstream bandwidth configuration combinations and at least one group of downstream bandwidth configuration combinations can be generated. Such as: in connection with the example given in S122 above, the server 1 combines the upstream bandwidth in bandwidth combination 1 with identification code 1 with the upstream bandwidth in bandwidth combination 1 with identification code 2, thereby forming upstream bandwidth configuration combination 1. Likewise, the server 1 combines the upstream bandwidth in the bandwidth combination 2 with the identification code 1 with the upstream bandwidth in the bandwidth combination 2 with the identification code 2, thereby forming the upstream bandwidth configuration combination 2. The forming process of each uplink bandwidth configuration combination from the uplink bandwidth configuration combination 3 to the uplink bandwidth configuration combination j is the same as the forming process of the uplink bandwidth configuration combination 1 and the uplink bandwidth configuration combination 2, and details are not repeated here. Then, the uplink bandwidth allocation combination 1-uplink bandwidth allocation combination j are summarized to obtain a summarized result shown in table 5. In addition, in combination with the example given in S122 above, the server 1 combines the downlink bandwidth in the bandwidth combination 1 with the identification code of 1 with the downlink bandwidth in the bandwidth combination 1 with the identification code of 2, thereby forming the downlink bandwidth configuration combination 1. Likewise, the server 1 combines the downlink bandwidth in the bandwidth combination 2 with the identification code 1 with the downlink bandwidth in the bandwidth combination 2 with the identification code 2, thereby forming the downlink bandwidth configuration combination 2. The forming process of each downlink bandwidth configuration combination from the downlink bandwidth configuration combination 3 to the downlink bandwidth configuration combination j is the same as the forming process of the downlink bandwidth configuration combination 1 and the downlink bandwidth configuration combination 2, and details are not repeated here. Then, the downlink bandwidth allocation combination 1 — the downlink bandwidth allocation combination j are summarized to obtain a summarized result shown in table 6.

The above example is described by taking as an example that the total number of bandwidth combinations included in each wireless node currently served by the server 1 is the same. In other examples, the total number of bandwidth combinations each wireless node currently served by the server 1 contains is not necessarily the same. Illustratively, it is assumed that the total number of bandwidth combinations contained in the theoretical bandwidth information of the wireless node with the identification code of 1 is 3, and the total number of bandwidth combinations contained in the theoretical bandwidth information of the wireless node with the identification code of 2 is 2. After that, the server 1 combines the upstream bandwidth in the bandwidth combination 1 with the identification code of 1 with the upstream bandwidth in the bandwidth combination 1 with the identification code of 2, thereby forming an upstream bandwidth configuration combination 1. The server 1 combines the upstream bandwidth in the bandwidth combination 2 with the identification code 1 with the upstream bandwidth in the bandwidth combination 2 with the identification code 2, thereby forming an upstream bandwidth configuration combination 2. When the server generates the uplink bandwidth configuration combination 3, since the total number of bandwidth combinations included in the theoretical bandwidth information of the wireless node whose identification code is 2, the server only needs to form the uplink bandwidth configuration combination 3 according to the uplink bandwidth in the bandwidth combination 2 whose identification code is 1. Similarly, the server 1 combines the downlink bandwidth in the bandwidth combination 1 with the identification code 1 with the downlink bandwidth in the bandwidth combination 1 with the identification code 2, thereby forming the downlink bandwidth configuration combination 1. The server 1 combines the downlink bandwidth in the bandwidth combination 2 with the identification code being 1 with the downlink bandwidth in the bandwidth combination 2 with the identification code being 2, thereby forming a downlink bandwidth configuration combination 2. When the server generates the downlink bandwidth configuration combination 3, the total number of the bandwidth combinations contained in the theoretical bandwidth information of the wireless node with the identification code of 2 is 2, so that the wireless node with the identification code of 2 does not have the bandwidth combination 3. Therefore, the server only needs to form the downstream bandwidth configuration combination 3 according to the downstream bandwidth in the bandwidth combination 2 with the identification code of 1.
S131, the server 1 determines a target bandwidth configuration combination according to at least one group of bandwidth configuration combinations and network parameters reported by each terminal in at least one terminal in a coverage area reported by each wireless node.
In an implementation manner, the target bandwidth configuration combination includes an uplink bandwidth configuration combination and a downlink bandwidth configuration combination. For example, the uplink bandwidth configuration combination may be any one of the uplink bandwidth configuration combinations shown in table 5, such as uplink bandwidth configuration combination 1. The downstream bandwidth configuration combination may be any one of the downstream bandwidth configuration combinations as shown in table 6, such as the downstream bandwidth configuration combination 1.
S132, the server 1 determines the target bandwidth information of each wireless node in the next period as the uplink bandwidth and the downlink bandwidth corresponding to each wireless node in the target bandwidth configuration combination.
In an implementation manner, when the bandwidth configuration of the wireless node changes, in order to ensure that the terminals in the coverage area of the wireless node communicate normally, after the wireless node reconfigures the bandwidth, it needs to notify each terminal in the coverage area of the wireless node that the bandwidth is also reconfigured, so as to ensure that the bandwidth configuration information used by the terminal is the same as the bandwidth configuration information of the wireless node. Such as: with reference to the above example of S130, the server 1 determines that the uplink bandwidth configuration combination in the target bandwidth configuration combination of the wireless node with the identification code 1 and the wireless node with the identification code 2 is the uplink bandwidth configuration combination 1, and the downlink bandwidth configuration combination is the downlink bandwidth configuration combination 2. Thus, the wireless node with the identifier number 1 has the uplink bandwidth of the next period

The wireless node with the identification code of 2 has the uplink bandwidth of the next period

The downlink bandwidth of the wireless node with the identification code of 2 in the next period is

Figure BDA0003338657700000173
Then, the wireless node with the identifier 1 may notify the core network that the bandwidth configuration of the next cycle has been completed. Similarly, only each terminal in the coverage area of the wireless node with the identification code of 2 feeds back that the uplink bandwidth of the next period is configured to be the uplink bandwidth of the next period

Then, the wireless node with the identification code of 2 can inform the core network that the bandwidth configuration of the next period is completed. Therefore, the terminal can establish communication connection with the core network, and the user experience is guaranteed.
In an implementation manner, the network parameters include actual reference signal received power RSRP, reference signal transmission power, and uplink bandwidth used by the currently serving wireless node, as shown in fig. 4 in conjunction with fig. 3, where S131 may be specifically implemented by following S1310-S1313.
S1310, the server 1 determines an uplink equivalent RSRP of each terminal in at least one terminal in the coverage area reported by each wireless node in each group of bandwidth configuration combinations according to at least one group of bandwidth configuration combinations, an actual RSRP reported by each terminal in at least one terminal in the coverage area reported by each wireless node, a transmission power of a reference signal, and an uplink bandwidth used by a currently serving wireless node.
In one possible implementation, the RSRP is the received power of the reference signal, and the transmit power of the reference signal of the wireless node is related to the Resource Block (RB) used by the wireless node when the transmit power of the wireless node is the same and there is a difference in the downlink bandwidth of the wireless node. Therefore, for terminals at the same position, since the path loss is the same, the difference of RSRP is mainly the difference of the total transmission power of the wireless nodes, and the server 1 may determine the uplink equivalent RSRP and the downlink equivalent RSRP according to the actual RSRP in the CSI reported by the terminals.
The Path Loss (PL) is determined by the Path attenuation constant PL0Path attenuation factor n and position r. Wherein PL (r) ═ PL0+10n log10(r) of (A). It can be seen that PL under different circumstances0Unlike n, table 7 gives the parameter configuration for 3 typical scenarios, as specified in the third Generation Partnership Project (3 GPP) 38.901:
TABLE 7
Figure BDA0003338657700000176
Figure BDA0003338657700000181
As can be seen from the parameter configuration of the above 3 typical scenarios, the path attenuation constant PL of the same terminal on the same wireless node can be found0Since the path attenuation factor n is the same as the position r, PL of the same terminal in the same wireless node is also the same. Since, RSRP ═ PReference toPL, so that it can be determined

the wireless node with the identification code of i represents the uplink bandwidth in the uplink bandwidth configuration combination j, M represents the sum of the number of terminals corresponding to each wireless node currently served by the server 1, and M belongs to [1, M ∈]M and M are integers, a represents a loss value, and a is a constant.
Then, for each terminal, the server 1 brings the actual RSRP of the terminal, the uplink bandwidth of the currently-served wireless node, and the uplink bandwidth in each uplink bandwidth configuration combination into formula one to obtain the uplink equivalent RSRP of each terminal at each wireless node. In this way, it can be determined that the uplink equivalent RSRP of each terminal on each wireless node under the same uplink bandwidth configuration combination.
For example, the uplink equivalent RSRP of each terminal on each wireless node under the same uplink bandwidth configuration combination is shown in table 8.
TABLE 8
Figure BDA0003338657700000191
In some examples, the uplink equivalent RSRP of each terminal on each wireless node under the same uplink bandwidth configuration combination may select the uplink equivalent RSRP of ToP2 as a final selection result, so that the computation flow may be simplified and the occupation of computation resources may be reduced.
S1311, the server 1 determines, according to a pre-stored correspondence between RSRP and uplink throughput and an uplink equivalent RSRP of each terminal in at least one terminal in a coverage area reported by each wireless node in each bandwidth configuration combination, a total uplink throughput of each bandwidth configuration combination.
In some examples, since the RSRP has a certain correlation with the uplink throughput, a fitting can be performed between the uplink throughput and the actual RSRP, so that a formula for representing the correlation between the uplink throughput and the actual RSRP can be determined. Such as: after fitting between the uplink throughput and the actual RSRP, determining a fitting formula Y-1.2111 x-10.387, wherein Y represents the uplink throughput, and x represents the actual RSRP. Specifically, after fitting between the uplink throughput and the actual RSRP, the fitting result is shown in fig. 5, where the abscissa represents the actual RSRP and the ordinate represents the uplink throughput.
And then, substituting the uplink equivalent RSRP of each terminal on each wireless node under each uplink bandwidth configuration combination into a fitting formula, and determining the total uplink throughput of each terminal under each uplink bandwidth configuration combination.

Illustratively, each uplink bandwidth configures uplink throughput corresponding to each equivalent RSRP of each terminal under the combination. Then, according to the uplink throughput corresponding to each equivalent RSRP of each terminal under each bandwidth configuration combination, the total uplink throughput of each uplink bandwidth configuration combination can be determined, and the total uplink throughput of the uplink bandwidth configuration combination j is equal to the sum of the uplink throughputs corresponding to each equivalent RSRP of each terminal under the bandwidth configuration combination j. The uplink throughput corresponding to each equivalent RSRP of each terminal under each uplink bandwidth configuration combination is shown in table 9, and the total uplink throughput of each uplink bandwidth configuration combination is shown in table 10.

S1312, the server 1 determines the bandwidth configuration combination corresponding to the maximum total uplink throughput according to the total uplink throughput of each group of bandwidth configuration combinations.
S1313, the server 1 uses the uplink bandwidth corresponding to each wireless node in the bandwidth configuration combination corresponding to the maximum total uplink throughput as the uplink bandwidth of each wireless node in the target bandwidth information of the next period.
In some examples, because the total uplink throughputs corresponding to different bandwidth configuration combinations are different, in the data transmission method provided in the embodiment of the present application, the uplink bandwidth corresponding to each wireless node in the bandwidth configuration combination corresponding to the maximum total uplink throughput is used as the uplink bandwidth of each wireless node in the target bandwidth information of the next period, so that each wireless node can be ensured to be in the optimal working interval to the maximum extent, so as to improve the utilization rate of the bandwidth resource.
For example, in combination with the example given in S1311, assuming that the total uplink throughput 1 corresponding to the uplink bandwidth configuration combination 1 is the maximum total uplink throughput, the uplink bandwidth corresponding to each wireless node of the uplink bandwidth configuration combination 1 may be determined as the uplink bandwidth of each wireless node in the target bandwidth information of the next period. As shown in table 5, assuming that the server 1 currently serves only the wireless node having the identification code 1 and the wireless node having the identification code 2, it is possible to determine the wireless node having the identification code 1The uplink bandwidth of the node in the next period is

In an implementation manner, the network parameters include actual reference signal received power RSRP, reference signal transmission power, and downlink bandwidth used by the currently serving wireless node, as shown in fig. 6 in conjunction with fig. 3, where S131 may be specifically implemented by the following S1314-S1317.
S1314, the server 1 determines, according to the at least one group of bandwidth configuration combinations, the actual RSRP reported by each terminal in the at least one terminal in the coverage area reported by each wireless node, the transmission power of the reference signal, and the downlink bandwidth used by the currently serving wireless node, a downlink equivalent RSRP of each terminal in the at least one terminal in the coverage area reported by each wireless node in each group of bandwidth configuration combinations.
In some examples, in connection with the example given above for S1310,

Specifically, the process of determining, by the server 1 according to formula 2, the downlink equivalent RSRP of each terminal on each wireless node under the same uplink bandwidth configuration combination is similar to the process of determining, by the server 1 in S1310, the downlink equivalent RSRP of each terminal on each wireless node under the same uplink bandwidth configuration combination, and details are not repeated here.
S1315, the server 1 determines, according to a pre-stored correspondence between RSRP and downlink throughput and a downlink equivalent RSRP of each terminal in at least one terminal in a coverage area reported by each wireless node in each bandwidth configuration combination, a total downlink throughput of each bandwidth configuration combination.
Specifically, the process of determining the total downlink throughput of each group of bandwidth configuration combinations by the server 1 according to the pre-stored corresponding relationship between the RSRP and the downlink throughput and the downlink equivalent RSRP of each terminal in the coverage range reported by each wireless node in each group of bandwidth configuration combinations is similar to the process of determining the total uplink throughput of each group of bandwidth configuration combinations by the server 1 according to the pre-stored corresponding relationship between the RSRP and the uplink throughput and the uplink equivalent RSRP of each terminal in the coverage range reported by each wireless node in each group of bandwidth configuration combinations, and is not described herein again.
