Path loss, or Propagation Loss (PL), refers to the loss generated by radio waves propagating in space, and is caused by radiation spread of transmit power and propagation characteristics of a channel, reflecting the change in the power average of received signals in a macroscopic range.
The reference signal received power (Reference Signal Receiving Power, RSRP) is one of the key parameters that can represent the radio signal strength and the physical layer measurement requirements in an LTE network, and is the average of the signal power received over all Resource Elements (REs) that carry the reference signal within a certain symbol.
Throughput refers to the amount of data (measured in bits, bytes, packets, etc.) successfully transferred per unit time for a network, device, port, virtual circuit, or other facility.
The following describes a data transmission method provided by the embodiment of the present invention, taking an electronic device as a server 1 as an example, in conjunction with the communication system shown in fig. 1.
As shown in fig. 2, the data transmission method includes the contents of the following steps S11 to S14:
s11, the server 1 receives the perception information reported by each wireless node in at least one wireless node served in the current period. The sensing 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 one embodiment, the server 1 only obtains the sensing information reported by each wireless node of the current service, and communication can be performed between different servers 1. When the terminal reports network parameters, the terminal only reports the sensing information to the wireless node serving the terminal currently.
For example, the terminal may periodically acquire network parameters, such as once per 1 transmission time interval (Transport Time Interval, TTI) by the terminal. In order to report the network parameters to the wireless node, the terminal may report the network parameters encapsulated in channel state information (Channel State Information, CSI) information to the wireless node, or the terminal may report the network parameters encapsulated in measurement report (Measurement Report, MR) data to the wireless node, or the terminal may report the network parameters directly to the wireless node.
Exemplary network parameters reported by the terminal are shown in table 1.
TABLE 1
Figure BDA0003338657700000091
The method comprises the steps that I represents an ith wireless node currently served by a server 1, UEin represents an nth terminal in a coverage area of the ith wireless node, CSI-UEin represents CSI information reported by the nth terminal in the coverage area of the ith wireless node, I epsilon [1, I ], N epsilon [1, N ], I represents the total number of wireless nodes currently served by the server 1, N represents the total number of terminals contained in the coverage area of the wireless node, and I, N, I and N are integers.
For example, 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 parameters 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 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.
As can be seen from the foregoing, in the data transmission method provided by the present invention, the server 1 receives the perceived 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 identifier 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 area reported by each wireless node. In this way, 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 moment of each wireless node currently served by the server 1 is changed according to the perception 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 one implementation manner, as shown in fig. 3 in conjunction with fig. 2, S12 may be specifically implemented by S120-S122 described below.
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 indicating the network management system to query theoretical bandwidth information corresponding to the identification code reported by each wireless node.
In an embodiment, the 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 inquiry request, the network management system inquires theoretical bandwidth information corresponding to the identification code reported by each wireless node in the bandwidth inquiry request.
Illustratively, taking J bandwidth combinations for each wireless node as an example, 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 Table 3
Figure BDA0003338657700000111
Figure BDA0003338657700000121
Wherein j is E [1, J]，
Figure BDA0003338657700000122
Representing the upstream bandwidth in the jth bandwidth combination supported by the ith wireless node,
Figure BDA0003338657700000123
and the downlink bandwidth in the jth bandwidth combination supported by the ith wireless node is represented, and J and J are integers.
In this way, when the server 1 needs to determine the theoretical bandwidth information supported by the wireless nodes, a 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 theoretical bandwidth information corresponding to the identification code reported by each wireless node in the bandwidth query request in table 3, so that 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 codes 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, assume that server 1 is currently serving only 2 wireless nodes, namely wireless node with identification code 1 and wireless node with 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, and after the network management system receives the bandwidth query request, 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, and the query result is shown in a table 4.
TABLE 4 Table 4
Figure BDA0003338657700000131
And then, the server 1 receives theoretical bandwidth information corresponding to the identification codes reported by each wireless node and sent by the network management system. And the server 1 determines theoretical bandwidth information supported by the wireless node with the identification code of 1 as the theoretical bandwidth information corresponding to the identification code of 1 in the table 4 and theoretical bandwidth information supported by the wireless node with the identification code of 2 as the theoretical bandwidth information corresponding to the identification code of 2 in the table 4 according to the theoretical bandwidth information corresponding to the identification code reported by each wireless node.
The above example is illustrated by taking the case that the server 1 sends the bandwidth query request carrying the identifier code reported by each wireless node to the network management system, and the server 1 determines the theoretical bandwidth information supported by each wireless node according to the theoretical bandwidth information corresponding to the identifier code reported by each wireless node generated by 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 served, 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 codes reported by each wireless node can be directly queried, and the processing delay is reduced.
In one implementation manner, the theoretical bandwidth information includes at least one uplink bandwidth and at least one downlink bandwidth, the target bandwidth information includes one uplink bandwidth and one downlink bandwidth, and as shown in fig. 3 in conjunction with fig. 2, the above S13 may be specifically implemented by the following S130-S132.
S130, the server 1 determines at least one group of bandwidth configuration combinations according to the theoretical bandwidth information. The bandwidth configuration combination comprises an uplink bandwidth and a downlink bandwidth corresponding to each wireless node.
In one embodiment, the bandwidth configuration combinations include an upstream bandwidth configuration combination and a downstream 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 re-combines the upstream bandwidth and the downstream bandwidth in each bandwidth combination, so that at least one set of upstream bandwidth configuration combinations and at least one set 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 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 the 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 an upstream bandwidth allocation combination 2. The forming process of each uplink bandwidth configuration combination in the uplink bandwidth configuration combination 3 and 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 will not be repeated here. Then, the uplink bandwidth allocation combination 1-the uplink bandwidth allocation combination j are summarized to obtain the summary results shown in table 5. Further, in combination with the example given in S122 above, the server 1 combines the downstream bandwidth in the bandwidth combination 1 with the identification code of 1 with the downstream bandwidth in the bandwidth combination 1 with the identification code of 2, thereby forming the downstream bandwidth configuration combination 1. Likewise, the server 1 combines the downstream bandwidth in the bandwidth combination 2 with the identification code of 1 with the downstream bandwidth in the bandwidth combination 2 with the identification code of 2, thereby forming a downstream bandwidth configuration combination 2. The forming process of each of the downlink bandwidth configuration combinations 3 to j is the same as the forming process of the downlink bandwidth configuration combination 1 and the downlink bandwidth configuration combination 2, and will not be described here again. Then, the downstream bandwidth allocation combinations 1 to j are summarized to obtain the summary results shown in table 6.

The above example is described taking as an example that the total number of bandwidth combinations contained 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 server 1 does not have to be the same. Illustratively, assume that the total number of bandwidth combinations included in the theoretical bandwidth information of the wireless node whose identification code is 1 is 3, and the total number of bandwidth combinations included in the theoretical bandwidth information of the wireless node whose identification code 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 allocation combination 2. When the server generates the upstream bandwidth allocation 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 upstream bandwidth allocation combination 3 from the upstream bandwidths in the bandwidth combination 2 whose identification code is 1. Similarly, the server 1 combines the downstream bandwidth in the bandwidth combination 1 with the identification code of 1 with the downstream bandwidth in the bandwidth combination 1 with the identification code of 2, thereby forming a downstream bandwidth configuration combination 1. The server 1 combines the downstream bandwidth in the bandwidth combination 2 with the identification code 1 with the downstream bandwidth in the bandwidth combination 2 with the identification code 2, thereby forming a downstream bandwidth configuration combination 2. When the server generates the downstream bandwidth allocation combination 3, since the total number of bandwidth combinations included in the theoretical bandwidth information of the wireless node with the identification code of 2 is 2, 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 bandwidths 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 the coverage area reported by each wireless node.
In one embodiment, the target bandwidth configuration combination includes an upstream bandwidth configuration combination and a downstream bandwidth configuration combination. Illustratively, the upstream bandwidth configuration combination may be any one of the upstream bandwidth configuration combinations as shown in table 5, such as upstream 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 downstream bandwidth configuration combination 1.
S132, the server 1 determines that the target bandwidth information of each wireless node in the next period is the uplink bandwidth and the downlink bandwidth corresponding to each wireless node in the target bandwidth configuration combination.
In one embodiment, when the bandwidth configuration of the wireless node changes, in order to ensure thatAfter the wireless node reconfigures the bandwidth, each terminal in the coverage area of the wireless node needs to be informed of reconfigurating the bandwidth again, so that the bandwidth configuration information used by the terminal is identical to the bandwidth configuration information of the wireless node. Such as: in connection with the above example of S130, the server 1 determines that the uplink bandwidth configuration combination in the target bandwidth configuration combination of both 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 identification code of 1 has the uplink bandwidth of the next period as follows

And when 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 user experience is guaranteed.
In an implementation manner, the network parameters include an actual reference signal received power RSRP, a reference signal transmission power, and an uplink bandwidth used by the currently serving wireless node, as shown in fig. 3 and fig. 4, and S131 may be specifically implemented by following S1310-S1313.
S1310, the server 1 determines the uplink equivalent RSRP of each terminal in at least one terminal in the coverage area reported by each wireless node in each bandwidth configuration combination according to at least one bandwidth configuration combination, the actual RSRP reported by each terminal in at least one terminal in the coverage area reported by each wireless node, the transmitting power of the reference signal and the uplink bandwidth used by the wireless node currently serving.
In one embodiment, the RSRP is a received power of a reference signal, and when the transmission power of the wireless node is the same and there is a difference in downlink bandwidth of the wireless node, the transmission power of the reference signal of the wireless node is related to a Resource Block (RB) used by the wireless node. Therefore, for the terminals in the same location, because the path loss is the same, the difference of RSRP is mainly the difference of the total transmission power of the wireless node, and the server 1 can determine the uplink equivalent RSRP and the downlink equivalent RSRP according to the actual RSRP in the CSI information reported by the terminals.
Path Loss (PL) is defined by a Path attenuation constant PL 0 The path attenuation factor n and the position r. Wherein PL (r) =pl 0 +10n log 10 (r). As can be seen, PL is achieved under different circumstances 0 Unlike n, table 7 gives the parameter configurations for 3 exemplary scenarios, as specified in the third generation partnership project (3rd Generation Partnership Project,3GPP) 38.901:
TABLE 7
Figure BDA0003338657700000176
Figure BDA0003338657700000181
From the parameter configuration of the 3 typical scenarios, it can find the path attenuation constant PL of the same terminal on the same wireless node 0 The path attenuation factor n and the location r are the same, so PL of the same terminal at the same radio node is also the same. Since rsrp=p Reference to PL, thus can be determined

And then, the server 1 brings the actual RSRP of the terminal, the uplink bandwidth of the wireless node currently serving and the uplink bandwidth in each uplink bandwidth configuration combination into a formula I for each terminal to obtain the uplink equivalent RSRP of each terminal at each wireless node. In this way, the uplink equivalent RSRP of each terminal on each wireless node can be determined under the same uplink bandwidth configuration combination.
Illustratively, 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 the final selection result, so as to simplify the calculation flow and reduce the occupation of the computing resource.
S1311, the server 1 determines the total uplink throughput of each group of bandwidth configuration combinations according to the corresponding relation between the pre-stored RSRP and the uplink throughput and the 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.
In some examples, since RSRP has a certain correlation with the upstream throughput, a fit between the upstream throughput and the actual RSRP may be made, so that a formula for representing the correlation of the two may be determined. Such as: after fitting between the uplink throughput and the actual RSRP, it is determined that the fitting formula y= -1.2111x-10.387, Y represents the uplink throughput, and x represents the actual RSRP. Specifically, after the uplink throughput and the actual RSRP may be fitted, the fitting result is shown in fig. 5, where the abscissa indicates the actual RSRP and the ordinate indicates the uplink throughput.
And then, carrying 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, the uplink throughput corresponding to each equivalent RSRP of each terminal under each uplink bandwidth configuration 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 throughput 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 a 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 there is a difference in total uplink throughput corresponding to different bandwidth configuration combinations, in the data transmission method provided by the embodiment of the present application, uplink bandwidth corresponding to each wireless node in the bandwidth configuration combination corresponding to the maximum total uplink throughput is used as uplink bandwidth of each wireless node in the target bandwidth information of the next period, so that each wireless node can be guaranteed to be in an optimal working interval to the greatest extent, so as to improve the utilization rate of bandwidth resources.
For example, in combination with the example given in S1311 above, 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 in the uplink bandwidth configuration combination 1 may be determined as the uplink bandwidth in the target bandwidth information of each wireless node in the next period. As shown in table 5, it is assumed that the server 1 currently serves only the wireless node with the identification code of 1 and the wireless node with the identification code of 2, and thus it is possible to determine that the wireless node with the identification code of 1 has the uplink bandwidth of the next period as

In an implementation manner, the network parameters include an actual reference signal received power RSRP, a reference signal transmission power, and a downlink bandwidth used by the currently serving wireless node, as shown in fig. 6 in conjunction with fig. 3, where S131 may be implemented specifically by following S1314-S1317.

Specifically, the process of determining, by the server 1, the downlink equivalent RSRP of each terminal on each wireless node in the same uplink bandwidth configuration combination according to formula 2 is similar to the process of determining, by the server 1, the downlink equivalent RSRP of each terminal on each wireless node in the same uplink bandwidth configuration combination in S1310, and is not repeated herein.
