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 at least comprises an identification code and network parameters reported by each terminal in at least one terminal in a coverage area, and one 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 reporting the perception information, the terminal only reports the perception information to the wireless node which serves the terminal currently.

For example, the terminal may acquire the sensing information periodically, e.g., the terminal acquires the sensing information once every 1 Transmission Time Interval (TTI). In order to Report the sensing Information to the wireless node, the terminal may encapsulate the sensing Information in Channel State Information (CSI) Information and Report the CSI Information to the wireless node, or the terminal encapsulates the sensing Information in Measurement Report (MR) data and reports the MR data to the wireless node, or the terminal directly reports the sensing Information to the wireless node.

For example, taking the example that the terminal can encapsulate the sensing information in the CSI information and report the CSI information to the wireless node, the CSI information reported by the terminal is shown in table 1.

TABLE 1

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.

With reference to the above example, the sensing information reported by the wireless node is shown in table 2.

TABLE 2

S12, the server 1 determines at least one frequency point information corresponding to each wireless node according to the identification code reported by each wireless node. The frequency point information at least comprises an uplink frequency point and a downlink frequency point.

S13, the server 1 determines the target uplink frequency point and the target downlink frequency point of each wireless node in the next period according to the at least one frequency point information and the network parameter reported by each terminal in the at least one terminal in the coverage area reported by each wireless node.

S14, the server 1 sends configuration information carrying the target uplink frequency point and the target downlink frequency point to each wireless node. The configuration information is used for indicating each wireless node to provide service according to the target uplink frequency point and the target downlink frequency point 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 of the current periodic service, so that at least one piece of frequency point information corresponding to each wireless node can be determined according to the identification code reported by each wireless node; and determining a target uplink frequency point and a target downlink frequency point of each wireless node in the next period according to the at least one frequency point information and the network parameters reported by each terminal in the at least one terminal in the coverage range reported by each wireless node. Therefore, the configuration information carrying the target uplink frequency point and the target downlink frequency point can be sent to each wireless node, so that each wireless node provides service according to the target uplink frequency point and the target downlink frequency point in the next period. Therefore, the uplink frequency point and the downlink frequency point of each wireless node currently served by the server 1 can be changed according to the sensing information reported by each wireless node, so that each wireless node can select a proper uplink frequency point and a proper downlink frequency point according to the requirement, and the problem of how to select a proper uplink frequency and a proper downlink frequency by the wireless node according to the actual requirement 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 frequency point query request carrying the identification code reported by each wireless node to the network management system. The frequency point query request is used for instructing a network management system to query at least one piece of frequency point 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, at least one piece of frequency point 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 at least one piece of frequency point information supported by the wireless nodes, a frequency point query request carrying the identification codes reported by each wireless node can be sent to the network management system. After receiving the frequency point query request, the network management system queries at least one piece of frequency point information corresponding to the identification code reported by each wireless node in the frequency point query request.

For example, it is described that each wireless node has J pieces of frequency point information, and at least one piece of frequency point information corresponding to the identification code of each wireless node stored in the network management system is shown in table 3.

TABLE 3

Wherein J is ∈ [1, J ∈ >]，

Represents the uplink frequency point in the jth frequency point information supported by the ith wireless node,

and the downlink frequency point in the jth frequency point information supported by the ith wireless node is represented, Wij represents the bandwidth in the jth frequency point information supported by the ith wireless node, and J and J are integers.

Therefore, when the server 1 needs to determine at least one piece of frequency point information supported by the wireless nodes, the server can send a frequency point query request carrying the identification code reported by each wireless node to the network management system. After receiving the frequency point query request, the network management system queries at least one piece of frequency point information corresponding to the identification code reported by each wireless node in the frequency point query request in table 3, so that at least one piece of frequency point information corresponding to the identification code reported by each wireless node can be determined.

S121, the server 1 receives at least one piece of frequency point information corresponding to the identification code reported by each wireless node and sent by the network management system.

S122, the server 1 determines at least one piece of frequency point information corresponding to each wireless node according to at least one piece of frequency point information corresponding to the identification code reported by each wireless node and sent by the network management system.

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 frequency point 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 at least one piece of frequency point information corresponding to the identification code 1 and at least one piece of frequency point information corresponding to the identification code 2 in the table 3 after receiving the frequency point query request, and the query result is shown in the table 4.

TABLE 4

And then, the server 1 receives at least one piece of frequency point information corresponding to the identification code reported by each wireless node and sent by the network management system. The server 1 determines at least one piece of frequency point information supported by the wireless node with the identification code of 1, such as at least one piece of frequency point information corresponding to the identification code of 1 in table 4, and at least one piece of frequency point information supported by the wireless node with the identification code of 2, such as at least one piece of frequency point information corresponding to the identification code of 2 in table 4, according to at least one piece of frequency point information corresponding to the identification code reported by each wireless node sent by the network management system.

The above example is described by taking an example that the server 1 sends a frequency point query request carrying an identification code reported by each wireless node to the network management system, and the server 1 determines at least one piece of frequency point information supported by each wireless node according to at least one piece of frequency point information corresponding to the identification code of each wireless node sent by the network management system. In other examples, the server 1 locally stores at least one piece of frequency point information corresponding to the identification codes of all the wireless nodes of the service, so that when the server 1 needs to determine at least one piece of frequency point information supported by the wireless nodes, at least one piece of frequency point information corresponding to the identification code reported by each wireless node can be directly queried, and processing delay is reduced.

In an implementation manner, as shown in fig. 4 in conjunction with fig. 2, the above S13 can be specifically realized by the following S130-S134.

S130, the server 1 determines at least one frequency point uplink combination according to the at least one frequency point information. And each frequency point uplink combination comprises an uplink frequency point corresponding to each wireless node.

In an implementable manner, the total number of the frequency point information corresponding to each wireless node currently served by the server 1 is the same, the total number of the frequency point uplink combinations included in each wireless node currently served by the server 1 is the same, and the total number of the frequency point downlink combinations included in each wireless node currently served by the server 1 is the same.

In this way, the server 1 recombines the uplink frequency points in each frequency point information, so as to generate at least one group of frequency point uplink combination. Such as: in combination with the example given in S122, the server 1 combines the uplink frequency point in the frequency point information 1 with the identification code of 1 with the uplink frequency point in the frequency point information 1 with the identification code of 2, so as to form the frequency point uplink combination 1. Similarly, the server 1 combines the uplink frequency point in the frequency point information 2 with the identification code 1 with the uplink frequency point in the frequency point information 2 with the identification code 2, thereby forming the frequency point uplink combination 2. The forming process of each frequency point uplink combination from the frequency point uplink combination 3 to the frequency point uplink combination j is the same as the forming process of the frequency point uplink combination 1 and the frequency point uplink combination 2, and the description is omitted here.

And then summarizing the frequency point uplink combination 1-the frequency point uplink combination j to obtain a summarized result shown in a table 5. In addition, in combination with the example given in S122 above, the server 1 may also combine the downlink frequency point in the frequency point information 1 with the identification code of 1 with the downlink frequency point in the frequency point information 1 with the identification code of 2, so as to form the frequency point downlink combination 1. Likewise, the server 1 combines the downlink frequency point in the frequency point information 2 with the identification code 1 with the downlink frequency point in the frequency point information 2 with the identification code 2, thereby forming the frequency point downlink combination 2. The forming process of each frequency point downlink combination from the frequency point downlink combination 3 to the frequency point downlink combination j is the same as the forming process of the frequency point downlink combination 1 and the frequency point downlink combination 2, and is not described herein again. Then, the frequency point downlink combination 1-frequency point downlink combination j are summarized to obtain the summarized result shown in table 6.

TABLE 5

TABLE 6

The above example is described by taking an example that the total number of the at least one frequency point information included in each wireless node currently served by the server 1 is the same. In other examples, the total number of the at least one frequency point information contained in each wireless node currently served by the server 1 is not necessarily the same. For example, it is assumed that the total number of frequency point information included in at least one frequency point information of a wireless node with an identification code of 1 is 3, and the total number of frequency point information included in at least one frequency point information of a wireless node with an identification code of 2 is 2.

Then, the server 1 combines the uplink frequency point in the frequency point information 1 with the identification code of 1 with the uplink frequency point in the frequency point information 1 with the identification code of 2, thereby forming the frequency point uplink combination 1. The server 1 combines the uplink frequency point in the frequency point information 2 with the identification code of 1 with the uplink frequency point in the frequency point information 2 with the identification code of 2, thereby forming a frequency point uplink combination 2. When the server generates the frequency point uplink combination 3, the total number of the frequency point information contained in the theoretical bandwidth information of the wireless node with the identification code of 2 is 2, so the server only needs to form the frequency point uplink combination 3 according to the uplink frequency point in the frequency point information 3 with the identification code of 1. Similarly, the server 1 combines the downlink frequency point in the frequency point information 1 with the identification code 1 with the downlink frequency point in the frequency point information 1 with the identification code 2, thereby forming the frequency point downlink combination 1. The server 1 combines the downlink frequency point in the frequency point information 2 with the identification code 1 with the downlink frequency point in the frequency point information 2 with the identification code 2, thereby forming a frequency point downlink combination 2. When the server generates the frequency point downlink combination 3, the total number of the frequency point information contained in the theoretical bandwidth information of the wireless node with the identification code of 2 is 2, so that the frequency point information 3 does not exist in the wireless node with the identification code of 2. Therefore, the server only needs to form the frequency point downlink combination 3 according to the downlink frequency point in the frequency point information 3 with the identification code of 1.

S131, the server 1 determines the equivalent uplink RSRP of each wireless node of each terminal in each frequency point uplink combination according to the at least one frequency point uplink combination and the network parameters reported by each terminal in at least one terminal in the coverage area reported by each wireless node.

In one implementable example, the network parameters include actual RSRP, actual uplink frequency point and actual downlink frequency point of the current wireless node.

The RSRP is the received power of the reference signal, and the transmission power of the reference signal is the same when the transmission power of the wireless nodes is the same, so for terminals at the same position, the difference of the RSRP is mainly the path loss, and the RSRP in the CSI reported by the terminal can be estimated according to the formula of the path loss in the third Generation Partnership Project (3 GPP)38.901, so as to determine the equivalent uplink RSRP and the equivalent downlink RSRP.

The Path Loss (PL) is determined by the Path attenuation constant PL₀Path attenuation factor n and position r. Wherein PL (r) ═ PL₀+10nlog₁₀(r) of (A). It can be seen that PL under different circumstances₀Unlike n, table 7 shows the parameter configuration of 3 typical scenarios, as specified in 3GPP 38.901:

TABLE 7

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 ═ P_{Reference to}PL, so that it can be determined

indicating that the mth terminal under the frequency point uplink combination j has no identification code of iTheoretical uplink frequency points on the line nodes, 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 ∈]And M and M are integers.

Then, for each terminal, the server 1 brings the actual RSRP of the terminal, the actual uplink frequency point of the current wireless node, and the uplink frequency point of the uplink combination of each frequency point into formula one, so as to obtain the equivalent uplink RSRP of each terminal at each wireless node. In this way, the equivalent uplink RSRP of each terminal on each wireless node under the same frequency point uplink combination can be determined.

For example, the equivalent uplink RSRP of each terminal on each wireless node under the same frequency point uplink combination is shown in table 8.

TABLE 8

In some examples, the equivalent uplink RSRP of each terminal on each wireless node under the same frequency point uplink combination may select the equivalent uplink RSRP of ToP2 as a final selection result, so that the calculation process may be simplified and the occupation of calculation resources may be reduced.

S132, the server 1 determines the uplink throughput of each wireless node of each terminal in each frequency point uplink combination according to the equivalent uplink RSRP of each wireless node of each terminal in each frequency point uplink 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 equivalent uplink RSRP of each terminal on each wireless node under each frequency point uplink combination into a fitting formula Y-1.2111 x-10.387, and determining the uplink throughput of each terminal under each frequency point uplink combination.

Illustratively, the uplink throughput corresponding to each equivalent uplink RSRP of each terminal under each frequency point uplink combination is shown in table 9.

TABLE 9

S133, the server 1 determines the total uplink throughput of the uplink combination of each frequency point according to the uplink throughput of each wireless node of the uplink combination of each terminal at each frequency point.

In some examples, the total uplink throughput of the frequency point uplink combination j is equal to the sum of uplink throughputs corresponding to each equivalent uplink RSRP of each terminal under the frequency point uplink combination j.

Wherein the content of the first and second substances,

wherein the content of the first and second substances,

and the uplink throughput corresponding to the equivalent uplink RSRP of the mth terminal at the frequency point uplink combination j is shown.

Illustratively, the total uplink throughput of the uplink combination for each frequency bin is shown in table 10.

S134, the server 1 determines the target uplink frequency point of each wireless node in the next period according to the total uplink throughput of the uplink combination of each frequency point.

In some practical manners, because the total uplink throughputs corresponding to different frequency point uplink combinations are different, the uplink frequency point corresponding to each wireless node in the frequency point uplink combination corresponding to the maximum total uplink throughput is used as the target uplink frequency point of each wireless node in the next period, so that each wireless node can be ensured to be in the optimal working interval to the maximum extent, and the utilization rate of the frequency point resources is improved.

For example, in combination with the example given in S133 above, assuming that the total uplink throughput 1 corresponding to the frequency point uplink combination 1 is the maximum total uplink throughput, an uplink frequency point corresponding to each wireless node in the frequency point uplink combination 1 may be determined as an uplink frequency point 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 provides services only for the wireless node with the identification code 1 and the wireless node with the identification code 2, and therefore it can be determined that the wireless node with the identification code 1 is at the uplink frequency point of the next cycle

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

In an implementation manner, as shown in fig. 6 in conjunction with fig. 2, the above S13 can be specifically realized by the following S135-S139.

And S135, the server 1 determines at least one frequency point downlink combination according to the at least one frequency point information. And each frequency point downlink combination comprises a downlink frequency point corresponding to each wireless node.

In some practical examples, the server 1 recombines the downlink frequency points in each frequency point information, so as to generate at least one group of frequency point downlink combination. Such as: in combination with the example given in S122, the server 1 combines the downlink frequency point in the frequency point information 1 with the identification code of 1 with the downlink frequency point in the frequency point information 1 with the identification code of 2, so as to form the frequency point downlink combination 1. Likewise, the server 1 combines the downlink frequency point in the frequency point information 2 with the identification code 1 with the downlink frequency point in the frequency point information 2 with the identification code 2, thereby forming the frequency point downlink combination 2. The forming process of each frequency point downlink combination from the frequency point downlink combination 3 to the frequency point downlink combination j is the same as the forming process of the frequency point downlink combination 1 and the frequency point downlink combination 2, and is not described herein again.

S136, the server 1 determines the equivalent downlink RSRP of each wireless node of each terminal in each frequency point downlink combination according to the at least one frequency point downlink combination and the network parameters reported by each terminal in at least one terminal in the coverage area reported by each wireless node.

In some practical examples, in connection with the example given above for S130,

wherein the content of the first and second substances,

indicating the equivalent downlink RSRP of the mth terminal under the frequency point downlink combination j on the wireless node with the identification code i,

representing the theoretical path loss of the mth terminal under the frequency point downlink combination j on the wireless node with the identification code i,

the actual downlink frequency point reported by the mth terminal is represented,

and the theoretical downlink frequency point of the mth terminal under the frequency point downlink combination j on the wireless node with the identification code i is represented.

Then, for each terminal, the server 1 brings the actual RSRP of the terminal, the actual downlink frequency point of the current wireless node, and the downlink frequency point of the downlink combination of each frequency point into formula two, so as to obtain the equivalent downlink RSRP of each terminal at each wireless node. In this way, the equivalent downlink RSRP of each terminal on each wireless node under the same frequency point downlink combination can be determined.

For example, the equivalent downlink RSRP of each terminal at each wireless node under the same frequency point downlink combination is shown in table 11.

TABLE 11

In some examples, the equivalent downlink RSRP of each terminal on each wireless node under the same frequency point downlink combination may select the equivalent downlink RSRP of ToP2 as a final selection result, so that the calculation process may be simplified and the occupation of calculation resources may be reduced.

S137, the server 1 determines the downlink throughput of each wireless node of each terminal in each frequency point downlink combination according to the equivalent downlink RSRP of each wireless node of each terminal in each frequency point downlink combination.

In some examples, since the RSRP also has a certain correlation with the downlink throughput, a fitting can be performed between the downlink throughput and the actual RSRP, so that a formula for representing the correlation between the downlink throughput and the actual RSRP can be determined. Such as: after fitting can be carried out between the downlink throughput and the actual RSRP, a fitting formula Y is determined to be ax-b, Y represents the downlink throughput, x represents the actual RSRP, and a and b are constants. And then, substituting the equivalent downlink RSRP of each terminal on each wireless node under each frequency point downlink combination into a fitting formula Y ═ ax-b, and determining the downlink throughput of each terminal under each frequency point downlink combination.

Illustratively, the downlink throughput corresponding to each equivalent downlink RSRP of each terminal under each frequency point downlink combination is shown in table 12.

TABLE 12

S138, the server 1 determines the total downlink throughput of each frequency point downlink combination according to the downlink throughput of each wireless node of each terminal in each frequency point downlink combination.

In some examples, the total downlink throughput of the frequency point downlink combination j is equal to the sum of downlink throughputs corresponding to each equivalent downlink RSRP of each terminal under the frequency point downlink combination j.

wherein the content of the first and second substances,

And S139, the server 1 determines the target downlink frequency point of each wireless node in the next period according to the total downlink throughput of the downlink combination of each frequency point.

In some implementable manners, the server 1 determines, according to the total downlink throughput of each frequency point downlink combination, that the downlink frequency point of each wireless node in the frequency point downlink combination corresponding to the maximum total downlink throughput is the target downlink frequency point of each wireless node in the next period.

For example, in combination with the example given in S138 above, assuming that the total downlink throughput 1 corresponding to the frequency point downlink combination 1 is the maximum total downlink throughput, it may be determined that the downlink frequency point corresponding to each wireless node in the frequency point downlink combination 1 is regarded as each none-exists frequency pointAnd the line node is at the downlink frequency point in the target bandwidth information of the next period. As shown in table 6, it is assumed that the server 1 currently provides services only for the wireless node with the identification code 1 and the wireless node with the identification code 2, and therefore it can be determined that the wireless node with the identification code 1 has the downlink frequency point in the next cycle

The wireless node with the identification code of 2 has the downlink frequency point of the next period

In addition, when the bandwidth configuration of the wireless node is changed, in order to ensure that the terminals in the coverage area of the wireless node communicate normally, after the wireless node reconfigures the uplink frequency point and the downlink frequency point, it needs to notify each terminal in the coverage area of the wireless node to reconfigure the uplink frequency point and the downlink frequency point again, so that it can be ensured that the uplink frequency point used by the terminal is the same as the uplink frequency point used by the wireless node, and the downlink frequency point used by the terminal is the same as the downlink frequency point used by the wireless node. Such as: in combination with the examples given in S134 and S190, the server determines that the wireless node with the identifier 1 has an uplink frequency point in the next period of

The wireless node with the identification code of 1 has the downlink frequency point of the next period
