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

Throughput (Throughput) refers to the amount of data (measured in bits, bytes, packets, etc.) successfully transmitted per unit of time to a network, device, port, virtual circuit, or other facility.

The following describes a data transmission method provided by an embodiment of the present invention, with reference to the communication system shown in fig. 1 and taking an electronic device as a server 1 as an example.

As shown in fig. 2, the data transmission method includes the following steps S11 to S14:

s11, the server 1 receives perception information reported by each wireless node in at least one wireless node which is served in the current period. The sensing information comprises network parameters reported by each terminal in at least one terminal in a coverage area.

In an implementation manner, the server 1 only obtains the sensing information reported by each currently serving wireless node, and communication can be performed between different servers 1. When the terminal reports the network parameters, the terminal only reports the perception information to the wireless node which is currently served for the terminal.

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

Exemplarily, the network parameters reported by the terminal are 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 range of the ith wireless node, CSI-UEin represents CSI information reported by the nth terminal in the coverage range 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 the terminals included in the coverage range of the wireless node, and I, N, I and N are integers.

For example, the example is described in which the terminal encapsulates the network parameters in CSI information and reports the CSI information to the wireless node, and the sensing information reported by the wireless node is shown in table 2.

TABLE 2

S12, the server 1 determines at least one theoretical parameter corresponding to each wireless node. The theoretical parameters at least comprise theoretical transmitting power of the wireless node and theoretical RB number required by the reference signal.

S13, the server 1 determines the target parameter of each wireless node in the next period according to at least one theoretical parameter and the network parameter reported by each terminal in at least one terminal in the coverage range reported by each wireless node. Wherein the target parameter is any one of at least one theoretical parameter.

S14, the server 1 sends configuration information carrying the target parameters to each wireless node. The configuration information is used for indicating each wireless node to provide service according to the target parameters in the next period.

In the data transmission method provided by the present invention, after receiving the sensing information reported by each wireless node in at least one wireless node served in the current period, the server 1 needs to determine at least one theoretical parameter corresponding to each wireless node; and determining the target parameter of each wireless node in the next period according to at least one theoretical parameter and the network parameter reported by each terminal in at least one terminal in the coverage range reported by each wireless node. In this way, the configuration information carrying the target parameter can be sent to each wireless node, so that each wireless node provides service according to the target parameter in the next period. Therefore, the transmission power of each wireless node currently served by the server 1 can be changed at any time according to the sensing information reported by each wireless node, so that the proper transmission power can be selected according to actual requirements, and the problem of how to select the proper transmission power according to the actual requirements by the wireless nodes in the 6G network in the related art is solved.

In one implementable manner, the sensory information further includes: identification codes, one identification code corresponding to one wireless node; referring to fig. 2, as shown in fig. 3, S12 may be implemented in S120.

S120, the server 1 determines at least one theoretical parameter corresponding to each wireless node according to the identification code reported by each wireless node.

In one possible implementation, each wireless node corresponds to an identification code. Therefore, the server 1 determines at least one theoretical parameter corresponding to each wireless node according to the identification code reported by each wireless node, so that the server 1 can manage the at least one theoretical parameter of each wireless node conveniently.

In an implementation manner, as shown in fig. 4 in conjunction with fig. 3, the above S120 can be specifically realized by the following S1200-S1202.

S1200, the server 1 sends a query request carrying the identification code reported by each wireless node to the network management system. The query request is used for instructing the network management system to query at least one theoretical parameter 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 theoretical parameter 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 at least one theoretical parameter supported by the wireless nodes, a query request carrying the identification codes reported by each wireless node can be sent to the network management system. After receiving the query request, the network management system queries at least one theoretical parameter corresponding to the identification code reported by each wireless node in the query request

Illustratively, each wireless node has J theoretical parameters, and at least one theoretical parameter corresponding to the identification code of each wireless node stored in the network management system is shown in table 3.

TABLE 3

Wherein j belongs to [1, J ], pij represents the theoretical transmitting power of the wireless node of the ith wireless node currently served by the server in the jth power combination, and nij represents the theoretical number of Resource Blocks (RB) needed by the reference signal of the ith wireless node currently served by the server in the jth power combination.

Thus, when the server 1 needs to determine at least one theoretical parameter corresponding to the wireless node, the server can send a query request carrying the identification code reported by each wireless node to the network management system. After receiving the query request, the network management system queries at least one theoretical parameter corresponding to the identification code reported by each wireless node in table 3, so that at least one theoretical parameter corresponding to the identification code reported by each wireless node can be determined.

S1201, the server 1 receives at least one theoretical parameter corresponding to the identification code reported by each wireless node and sent by the network management system.

S1202, the server 1 determines at least one theoretical parameter supported by each wireless node according to at least one theoretical parameter corresponding to the identification code reported by each wireless node.

For example, it is assumed that the server 1 currently serves only 2 wireless nodes, namely a wireless node with an identification code of 1 and a wireless node with an identification code of 2. The server 1 sends a query request carrying the 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 theoretical parameter corresponding to the identification code 1 and at least one theoretical parameter corresponding to the identification code 2 in the table 3 after receiving the query request, and the query result is shown in the table 4.

TABLE 4

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

The above example is explained by taking an example that the server 1 sends a query request carrying the identification code reported by each wireless node to the network management system, and the server 1 determines at least one theoretical parameter supported by each wireless node according to at least one theoretical parameter corresponding to the identification code reported by each wireless node sent by the network management system. In some other examples, the server 1 locally stores at least one theoretical parameter corresponding to the identification codes of all the wireless nodes serving the wireless node, so that when the server 1 needs to determine at least one theoretical parameter supported by the wireless node, the server can directly query at least one theoretical parameter corresponding to the identification code reported by each wireless node, thereby reducing the processing delay.

In an implementation manner, as shown in fig. 3 in conjunction with fig. 2, the above S13 can be specifically realized by the following S130-S132.

S130, the server 1 determines at least one group of power configuration combination according to at least one theoretical parameter. Wherein the power configuration combination comprises theoretical parameters corresponding to each wireless node.

In a practical manner, each wireless node currently served by the server 1 contains the same total number of power configuration combinations. In this way, the server 1 recombines the power combinations of each wireless node, so that at least one set of power configuration combinations can be generated. Such as: in connection with the example given in S1200 above, the server 1 combines the theoretical transmission power P11 of the wireless node in the power combination 1 with the identification code of 1 with the theoretical number of resource blocks RB 11 required for the reference signal n11 and the theoretical transmission power P21 of the wireless node in the power combination 1 with the identification code of 2 with the theoretical number of resource blocks RB 21 required for the reference signal n21, thereby forming the power configuration combination 1. The server 1 combines the theoretical transmission power P12 of the wireless node in the power combination 2 with the identification code of 1 with the theoretical number of resource blocks RB 12 required for the reference signal and the theoretical transmission power P22 of the wireless node in the power combination 2 with the identification code of 2 with the theoretical number of resource blocks RB 22 required for the reference signal, thereby forming the power configuration combination 2. The forming process of each of the power configuration combinations 3 to j is similar to the forming process of the power configuration combination 1 and the power configuration combination 2, and is not described herein again. Then, the power allocation combination 1-the power allocation combination j are summarized to obtain the summarized result shown in table 5.

TABLE 5

The above example is described by taking as an example that the total number of power configuration combinations included in each wireless node currently served by the server 1 is the same. In other examples, the total number of power configuration combinations that each wireless node currently served by the server 1 contains is not necessarily the same. Illustratively, it is assumed that the total number of power combinations corresponding to the wireless node with the identification code of 1 is 3, and the total number of power combinations corresponding to the wireless node with the identification code of 2 is 2. Then, the server 1 combines the theoretical transmission power P11 of the wireless node and the number n11 of theoretical resource blocks RB required for the reference signal in the power combination 1 with the identification code 1 with the theoretical transmission power P21 of the wireless node and the number n21 of theoretical resource blocks RB required for the reference signal in the power combination 1 with the identification code 2, thereby forming the power configuration combination 1.

The server 1 combines the theoretical transmission power P12 of the wireless node in the power combination 2 with the identification code of 1 and the number n12 of theoretical resource blocks RB required for the reference signal with the theoretical transmission power P22 of the wireless node in the power combination 2 with the identification code of 2 and the number n22 of theoretical resource blocks RB required for the reference signal, thereby forming the power configuration combination 2. When the server generates the power configuration combination 3, since the wireless node with the identification code of 2 further includes 2 power combinations, the server only needs to form the power configuration combination 3 according to the theoretical transmission power P13 of the wireless node in the power combination 3 with the identification code of 1 and the theoretical number n13 of resource blocks RB needed by the reference signal.

S131, the server 1 determines a target configuration combination according to the at least one group of power configuration combination and the network parameter reported by each terminal in the at least one terminal in the coverage area reported by each wireless node. The target configuration combination is any one of at least one group of power configuration combinations.

Illustratively, in conjunction with the above example of S130, assuming that the target configuration combination is the power configuration combination 1, the theoretical parameters corresponding to each wireless node in the target configuration combination are shown in table 6.

TABLE 6

S132, the server 1 determines the target parameter of each wireless node in the next period as the theoretical parameter corresponding to each wireless node in the target configuration combination.

In an implementable manner, when the transmission power of the wireless node changes, in order to ensure that the terminals in the coverage area of the wireless node communicate normally, the wireless node needs to notify the core network that the new transmission power has been changed after reconfiguring the bandwidth. In this way, it can be guaranteed that the bandwidth configuration information used by the terminal is the same as the bandwidth configuration information of the wireless node. Such as: in connection with the above example of S131, the server 1 determines the power configuration combination 1 as the target configuration combination. Thus, the wireless node with the identification code of 1 configures the theoretical transmission power of the wireless node in the next period as P11, and configures the number of theoretical resource blocks RB required by the reference signal as n11, the wireless node with the identification code of 1 may notify the core network, and the transmission power in the next period is updated. Similarly, the wireless node with the identification code of 2 may notify the core network that the transmission power of the next period has been updated when the theoretical transmission power of the wireless node of the next period is P21 and the number of the theoretical resource blocks RB required by the reference signal is n21. Therefore, the terminal can establish communication connection with the core network, and the user experience is guaranteed.

In one implementable manner, the network parameters include: actual transmitting power of the current wireless node, actual number of Resource Blocks (RB) occupied by a reference signal, and actual Reference Signal Receiving Power (RSRP); referring to fig. 3, as shown in fig. 4, S131 may be implemented by S1310-S1313.

S1310, the server 1 determines an equivalent RSRP of each terminal according to the at least one group of power configuration combinations and the network parameter reported by each terminal in the coverage area reported by each wireless node.

In one implementation, the RSRP is the received power of the reference signal, and the transmitted power of the reference signal of the wireless node is related to the Resource Block (RB) used by the wireless node when the transmitted power of the wireless node is the same and there is a difference in the downlink bandwidth of the wireless node. Therefore, for the terminals at the same position, since the path loss is the same, the difference of the RSRP is mainly the difference of the total transmission power of the wireless nodes, and the server 1 may determine the equivalent RSRP according to the actual RSRP in the CSI reported by the terminal.

The Path Loss (PL) is determined by the Path attenuation constant PL ₀ Path attenuation factor n and position r. Wherein PL (r) = PL ₀ +10n log ₁₀ (r) of (A). It can be seen thatPL in the same Environment ₀ Unlike n, the parameter configuration for 3 typical scenarios is given as shown in table 7, as specified in the third Generation Partnership project (3 gpp) 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 found ₀ Since 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. As a result of this, it is possible to prevent,

P _RS representing the transmission power, P, of the reference signal _Launching Representing the transmission power, n, of the wireless node _RB Indicating the number of resource blocks RB occupied by the reference signal. It can thus be determined that,

the formula one.

Wherein the content of the first and second substances,

represents the actual transmission power of the current wireless node reported by the mth terminal, and->

Represents the number of the actual resource blocks RB occupied by the reference signal reported by the mth terminal, and/or>

The actual RSRP reported by the mth terminal, 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 each an integer.

Then, the server 1 brings the actual RSRP of each terminal in each group of power configuration combination, the actual transmission power of the wireless node, and the actual number of resource blocks RB occupied by the reference signal into the above formula one, to obtain the equivalent RSRP of each terminal at each wireless node. As such, an equivalent RSRP for each terminal on each wireless node under the same power configuration combination may be determined.

Illustratively, the equivalent RSRP per terminal per wireless node under the same power configuration combination is shown in table 8.

TABLE 8

In some examples, the equivalent RSRP of each terminal on each wireless node under the same power configuration combination may select the equivalent RSRP of ToP2 as a final selection result, so that the computation flow may be simplified and the occupation of computation resources may be reduced.

S1311, the server 1 determines the total downlink throughput of each group of power configuration combinations according to a pre-stored correspondence between RSRP and downlink throughput, and an equivalent RSRP of each terminal in at least one terminal in a coverage area reported by each wireless node in each group of power configuration combinations.

In some examples, since the RSRP 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 between the downlink throughput and the actual RSRP, determining a fitting formula Y = -1.2111x-10.387, wherein Y represents the downlink throughput, and x represents the actual RSRP. Specifically, after fitting can be performed between the downlink throughput and the actual RSRP, the fitting result is as shown in fig. 5, where the abscissa represents the actual RSRP and the ordinate represents the downlink throughput.

And then, substituting the equivalent RSRP of each terminal on each wireless node under each power configuration combination into a fitting formula, and determining the total downlink throughput of each terminal under each power configuration combination.

Wherein the content of the first and second substances,

wherein, the first and the second end of the pipe are connected with each other,

the total downlink throughput of the mth terminal under the power configuration combination j is shown, and T (RSRPmi) shows the downlink throughput corresponding to the equivalent RSRP of the mth terminal under the power configuration combination i.

Illustratively, the server 1 determines the downlink throughput corresponding to each equivalent RSRP of each terminal under each power configuration combination. Then, according to the downlink throughput corresponding to each equivalent RSRP of each terminal under each power configuration combination, the total downlink throughput of each power configuration combination may be determined, and the total downlink throughput of the power configuration combination j is equal to the sum of the downlink throughputs corresponding to each equivalent RSRP of each terminal under the power configuration combination j. The downlink throughput corresponding to each equivalent RSRP of each terminal under each power configuration combination is shown in table 9, and the total downlink throughput of each power configuration combination is shown in table 10.

TABLE 9

TABLE 10

Power configuration combination	Total downlink throughput
		1	Total downlink throughput 1
2	Total downlink throughput 2
		…	…
j	Total downlink throughput j

S1312, the server 1 determines the power configuration combination corresponding to the maximum total downlink throughput according to the total downlink throughput of each group of power configuration combinations.

S1313, the server 1 uses the theoretical transmission power corresponding to each wireless node in the power configuration combination corresponding to the maximum total downlink throughput as the transmission power of each wireless node in the next period.

In some examples, because the total downlink throughput corresponding to different power configuration combinations is different, in the data transmission method provided in the embodiment of the present application, the theoretical transmission power corresponding to each wireless node in the power configuration combination corresponding to the maximum total downlink throughput is used as the transmission power of each wireless node in the next period, so that each wireless node can be ensured to be in the optimal working interval to switch the transmission power flexibly according to actual requirements.

For example, in combination with the example given in S1311, assuming that the total downlink throughput 1 corresponding to the power configuration combination 1 is the maximum total downlink throughput, the theoretical transmission power corresponding to each wireless node of the power configuration combination 1 may be determined as the transmission power 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 transmission power of the wireless node with the identification code 1 in the next cycle is P11, the number of theoretical resource blocks RB required by the reference signal is n11, the transmission power of the wireless node with the identification code 2 in the next cycle is P21, and the number of theoretical resource blocks RB required by the reference signal is n21.

It should be noted that the current wireless node refers to a wireless node currently providing services for the terminal.
