The server 1 sends first configuration information carrying a target uplink frequency point and a target downlink frequency point to each wireless node. After receiving the first configuration information, the wireless node 2 configures an uplink frequency point and a downlink frequency point according to the target uplink frequency point and the target downlink frequency point in the first configuration information in the next period.

Some terms used in this disclosure have their ordinary and customary meaning in the industry. In addition, some terms will be explained when they appear in the present specification. It will be helpful to understand that several terms are specifically used herein. When referring to

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.

Frequency points refer to specific absolute frequency values. Typically the center frequency of the modulated signal. The frequency points are numbers given to fixed frequencies.

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 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 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. And when the terminal reports the sensing information, the terminal only reports the sensing information to the wireless node serving the terminal currently.

For example, the terminal may periodically obtain the awareness information, such as once every 1 transmission time interval (Transport Time Interval, TTI) by the terminal. In order to report the sensing information to the wireless node, the terminal may report the sensing information to the wireless node encapsulated in channel state information (Channel State Information, CSI) information, or the terminal may report the sensing information to the wireless node encapsulated in measurement report (Measurement Report, MR) data, or the terminal may report the sensing information directly to the wireless node.

For example, taking an 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

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.

In combination with the above example, the awareness 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 a target uplink frequency point and a target downlink frequency point of each wireless node in the next period according to at least one frequency point information and network parameters reported by each terminal in at least one terminal in a 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.

As can be seen from the foregoing, in the data transmission method provided by the present 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 as to determine at least one frequency point information corresponding to each wireless node 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 at least one terminal in the coverage area reported by each wireless node. In this way, 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 perception information reported by each wireless node, so that each wireless node can be ensured to select proper uplink frequency point and proper downlink frequency point according to the requirement, and the problem of how the wireless node selects proper uplink frequency and downlink frequency according to the actual requirement in the related art 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 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 indicating the network management system to query at least one frequency point information corresponding to the identification code reported by each wireless node.

In an embodiment, the network management system serves a plurality of servers 1, at least one frequency point information corresponding to the 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 frequency point information supported by the wireless nodes, a frequency point query request carrying the identification code 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 frequency point information corresponding to the identification code reported by each wireless node in the frequency point query request.

For example, taking J pieces of frequency point information of each wireless node as an example, 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 Table 3

Wherein j is E [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.

In this way, when the server 1 needs to determine at least one frequency point information supported by the wireless nodes, a frequency point query request carrying an identification code 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 frequency point information corresponding to the identification code reported by each wireless node in the frequency point query request in table 3, so as to determine at least one frequency point information corresponding to the identification code reported by each wireless node.

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

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 frequency point query request carrying an identification code (such as 1 and 2) reported by each wireless node to a network management system, and after the network management system receives the frequency point query request, the network management system queries at least one frequency point information corresponding to the identification code 1 and at least one frequency point 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

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

The above example is illustrated by taking the example that the server 1 sends the frequency point query request carrying the 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 frequency point information corresponding to the identification codes of all the wireless nodes served, so that when the server 1 needs to determine at least one frequency point information supported by the wireless nodes, the server can directly query at least one frequency point information corresponding to the identification codes reported by each wireless node, thereby reducing processing delay.

In one implementation manner, as shown in fig. 4 in conjunction with fig. 2, S13 may be specifically implemented by S130 to S134 described below.

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

In an implementation manner, the total number of frequency point information corresponding to each wireless node currently served by the server 1 is the same, the total number of frequency point uplink combinations included in each wireless node currently served by the server 1 is the same, and the total number of 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 that at least one group of frequency point uplink combinations can be generated. Such as: in combination with the example given in S122 above, 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. Similarly, 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. 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 is not repeated here.

Then, the frequency point uplink combinations 1 to j are summarized to obtain the summarized results shown in table 5. In addition, in combination with the example given in S122 above, the server 1 may further 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, thereby forming a frequency point downlink combination 1. Similarly, the server 1 combines the downlink frequency point in the frequency point information 2 with the identification code of 1 with the downlink frequency point in the frequency point information 2 with the identification code of 2, thereby forming a 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 will not be repeated here. Then, the frequency point downlink combination 1-frequency point downlink combination j is summarized to obtain the summarized result shown in table 6.

TABLE 5

TABLE 6

The above example is described taking as an example that the total number of at least one frequency point information contained in each wireless node currently served by the server 1 is the same. In some other examples, the total number of at least one frequency point information contained by each wireless node currently served by the server 1 is not necessarily the same. For example, assume that the total number of frequency point information included in at least one frequency point information of a wireless node whose identification code is 1 is 3, and the total number of frequency point information included in at least one frequency point information of a wireless node whose identification code 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, so as to form a 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, so as to form a frequency point uplink combination 2. When the server generates the frequency point uplink combination 3, since the total number of frequency point information contained in the theoretical bandwidth information of the wireless node with the identification code of 2 is 2, 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 of 1 with the downlink frequency point in the frequency point information 1 with the identification code of 2, so as to form a frequency point downlink combination 1. The server 1 combines the downlink frequency point in the frequency point information 2 with the identification code of 1 with the downlink frequency point in the frequency point information 2 with the identification code of 2, so as to form a frequency point downlink combination 2. When the server generates the frequency point downlink combination 3, the total number of frequency point information 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 frequency point information 3. 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 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 example, the network parameters include an actual RSRP, an actual upstream frequency point and an actual downstream frequency point of the current wireless node.

The RSRP is the received power of the reference signal, and when the transmission power of the wireless node is the same, the transmission power of the reference signal is the same, so that for the terminals at the same position, the difference of the RSRP is mainly path loss, the RSRP in the CSI reported by the terminals can be estimated according to the formula of the path loss in the third generation partnership project (3rd Generation Partnership Project,3GPP) 38.901, and the equivalent uplink RSRP and the equivalent downlink RSRP are determined.

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 +10nlog ₁₀ (r). As can be seen, PL is achieved under different circumstances ₀ Unlike n, table 7 gives the parameter configurations for 3 typical scenarios, as specified in 3gpp 38.901:

TABLE 7

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

Wherein, the liquid crystal display device comprises a liquid crystal display device,

And then, the server 1 brings the actual RSRP of each terminal, the actual uplink frequency point of the current wireless node and the uplink frequency point of each frequency point uplink combination into a formula I 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 can be determined under the same frequency point uplink combination.

Illustratively, 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 the final selection result, so as to simplify the calculation flow and reduce the occupation of the calculation resources.

S132, the server 1 determines the uplink throughput of each wireless node of each terminal uplink combination at each frequency point according to the equivalent uplink RSRP of each wireless node of each terminal uplink combination at each frequency point.

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 equivalent uplink RSRP of each terminal on each wireless node under each frequency point uplink combination into a fitting formula Y= -1.2111x-10.387, and determining the uplink throughput of each terminal under each frequency point uplink combination.

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

TABLE 9

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

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

indicating the total uplink throughput of the mth terminal in the frequency point uplink combination j,

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

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

S134, the server 1 determines a 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 embodiments, because there is a difference in total uplink throughput corresponding to different uplink combinations of frequency points, in the data transmission method provided by the embodiment of the present application, an uplink frequency point corresponding to each wireless node in the uplink combination of frequency points corresponding to the maximum total uplink throughput is used as a target uplink frequency point of each wireless node in the next period, so that each wireless node can be ensured to be in an optimal working interval to the greatest extent, so as to improve the utilization rate of frequency point resources.

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, the uplink frequency point corresponding to each wireless node in the frequency point uplink combination 1 may be determined as the 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 serves only the wireless node with the identification code of 1 and the wireless node with the identification code of 2, and thus it can be determined that the wireless node with the identification code of 1 is at the uplink frequency point of the next period

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

In one implementation manner, as shown in fig. 6 in conjunction with fig. 2, S13 may be specifically implemented by S135-S139 described below.

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

In some practical examples, the server 1 re-combines the downlink frequency points in each frequency point information, so that at least one set of frequency point downlink combinations can be generated. Such as: in combination with the example given in S122 above, 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, thereby forming the frequency point downlink combination 1. Similarly, the server 1 combines the downlink frequency point in the frequency point information 2 with the identification code of 1 with the downlink frequency point in the frequency point information 2 with the identification code of 2, thereby forming a 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 will not be repeated here.

S136, the server 1 determines the equivalent downlink RSRP of each wireless node of each terminal in each frequency point downlink combination according to 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.

Indicating the actual downlink frequency point reported by the mth terminal,

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

And then, 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 each frequency point downlink combination into a formula II for each terminal 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 can be determined under the same frequency point downlink combination.

Illustratively, the equivalent downlink RSRP of each terminal on 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 the final selection result, so as to simplify the calculation flow and reduce the occupation of the calculation resources.

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

In some examples, since RSRP also has a certain correlation with the downstream throughput, a fit between the downstream 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 downlink throughput and the actual RSRP, the fitting formula y=ax-b is determined, Y represents the downlink throughput, x represents the actual RSRP, and a and b are constants. And then, carrying 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.

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

In some embodiments, the server 1 determines, according to the total downlink throughput of each frequency point downlink combination, a downlink frequency point of each wireless node in the frequency point downlink combination corresponding to the maximum total downlink throughput as a 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, the downlink frequency point corresponding to each wireless node in the frequency point downlink combination 1 may be determined as the downlink frequency point in the target bandwidth information of each wireless node in the next period. As shown in table 6, 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 can be determined that the wireless node with the identification code of 1 is at the downlink frequency point of the next period

The wireless node with the identification code of 2 has the downlink frequency point of +.>

In addition, when the bandwidth configuration of the wireless node changes, in order to ensure the normal communication of the terminal in the coverage area of the wireless node, the wireless node reconfigures the uplink frequency point and the downlink frequency pointAfter that, each terminal in the coverage area needs to be informed to configure the uplink frequency point and the downlink frequency point again, so that the uplink frequency point used by the terminal and the uplink frequency point used by the wireless node, and the downlink frequency point used by the terminal and the downlink frequency point used by the wireless node are the same. Such as: in combination with the examples given in S134 and S190 above, the server determines that the wireless node with the identification code of 1 is at the uplink frequency point of the next period

The wireless node with the identification code of 2 has the uplink frequency point of +.>

The wireless node with the identification code of 1 is +.>

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

Then, the wireless node with the identification code of 1 needs to configure the uplink frequency point to be +.>

The downlink frequency point is configured as +.>

The wireless node with the identification code of 2 needs to configure the uplink frequency point to be +.>

The downlink frequency point is configured as +.>

Thus, the wireless node with the identification code of 1 also needs to inform each terminal in its coverage area that the uplink frequency point needs to be configured as +.>

The downlink frequency point is configured as +.>

The wireless node with the identification code of 2 also needs to inform each terminal in the coverage area of the wireless node that the uplink frequency point needs to be configured as +.>

The downlink frequency point is configured as +.>

Only when each terminal within the coverage area of the wireless node with the identification code of 1 feeds back that the uplink frequency point of the next period has been configured as +.>

The downstream frequency point of the next period is configured as +.>

And when the wireless node with the identification code of 1 can inform the core network, the reconfiguration of the uplink frequency point and the downlink frequency point of the next period is completed. Similarly, only if each terminal within the coverage area of the wireless node with the identification code of 2 feeds back that the uplink frequency point of the next period is configured to be +. >

The downstream frequency point of the next period is configured as +.>

And when the wireless node with the identification code of 2 can inform the core network, the reconfiguration of the uplink frequency point and the downlink frequency point of the next period is completed.
