Referring to fig. 1, fig. 1 is a flowchart of a data transmission method according to an embodiment of the present invention, and as shown in fig. 1, the method includes the following steps:
In the embodiment of the present invention, the throughput size requirement value may be the number of resource blocks allocated to the mobile terminal, or may be the throughput of the mobile terminal directly. The above throughput may be understood as the amount of successfully transmitted data per unit time, which may be measured using bits or bytes, etc.
And step 102, sequencing the throughput magnitude requirement values of the plurality of mobile terminals according to a rule from large to small.
In the embodiment of the present invention, if the throughput size requirement value of the mobile terminal a is 16, the throughput size requirement value of the mobile terminal B is 23, the throughput size requirement value of the mobile terminal C is 12, and the throughput size requirement value of the mobile terminal D is 44, the throughput size requirement values are sorted according to the rule from large to small into 44, 23, 16, and 12, and the mobile terminals corresponding to the throughput size requirement values are sorted into the mobile terminal D, the mobile terminal B, the mobile terminal a, and the mobile terminal C.

In the embodiment of the present invention, the size of the snr may represent the size of throughput, and the selecting of the target antenna sub-array that maximizes the receiving snr of the target mobile terminal is equal to selecting the target antenna sub-array that maximizes the throughput of the target mobile terminal. Because the target mobile terminal is the mobile terminal which is not paired and the current throughput size requirement value is ranked first, the target antenna subarray which is not paired and enables the receiving signal-to-noise ratio of the target mobile terminal to be the maximum can be paired with the target mobile terminal in the unpaired mobile terminals, the target mobile terminal can conduct data transmission with the antenna subarray which has the maximum signal-to-noise ratio in the unpaired mobile terminal as far as possible, the transmission efficiency is improved, and the requirements of different mobile terminals on the throughput are met as far as possible.
In an embodiment of the present invention, the Mobile terminal may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.

Therefore, the target antenna subarray which enables the receiving signal-to-noise ratio of the target mobile terminal to be the maximum is selected to be paired with the target mobile terminal, and the data transmission efficiency is improved.
Referring to fig. 2, fig. 2 is a flowchart of another data transmission method according to an embodiment of the present invention. The main difference between this embodiment and the previous embodiment is that each antenna sub-array in the method includes a plurality of radio frequency codebooks, and each radio frequency codebook records a receiving power preset for each of the plurality of mobile terminals. As shown in fig. 2, the method comprises the following steps:
In the embodiment of the present invention, the throughput size requirement value may be the number of resource blocks allocated to the mobile terminal, or may be the throughput of the mobile terminal directly. The above throughput may be understood as the amount of successfully transmitted data per unit time, which may be measured using bits or bytes, etc.
In the embodiment of the present invention, if the throughput size requirement value of the mobile terminal a is 16, the throughput size requirement value of the mobile terminal B is 23, the throughput size requirement value of the mobile terminal C is 12, and the throughput size requirement value of the mobile terminal D is 44, the throughput size requirement values are sorted according to the rule from large to small into 44, 23, 16, and 12, and the mobile terminals corresponding to the throughput size requirement values are sorted into the mobile terminal D, the mobile terminal B, the mobile terminal a, and the mobile terminal C.
In the embodiment of the invention, each antenna subarray comprises a plurality of radio frequency codebooks, and each radio frequency codebook records the receiving power preset for each mobile terminal in the plurality of mobile terminals. For example: the antenna subarray 1 comprises a radio frequency codebook 1, a radio frequency codebook 2 and a radio frequency codebook 3, wherein the radio frequency codebook 1 records that the preset receiving powers of a mobile terminal A, a mobile terminal B and a mobile terminal C can be respectively 50W, 60W and 70W; the radio frequency codebook 2 records that the preset receiving powers of the mobile terminal A, the mobile terminal B and the mobile terminal C can be 60W, 80W and 40W respectively; the radio codebook 3 records that the preset receiving powers for the mobile terminal a, the mobile terminal B and the mobile terminal C may be 100W, 65W and 75W, respectively, and so on.
In the embodiment of the present invention, the receiving signal-to-noise ratio of the target mobile terminal recorded by each radio frequency codebook is calculated according to the preset receiving power of the target mobile terminal recorded by each radio frequency codebook, which may be a correspondence table in which the receiving power and the receiving signal-to-noise ratio are stored in advance, and the receiving signal-to-noise ratio is directly obtained from the correspondence table; or the signal-to-noise ratio may be obtained by obtaining the noise power corresponding to the received power from a pre-stored correspondence table according to the received power, and taking the logarithm of the ratio of the received power to the noise power.
And 204, determining the maximum receiving signal-to-noise ratio in the plurality of the calculated receiving signal-to-noise ratios.
In the embodiment of the invention, for the mobile terminal A, the receiving signal-to-noise ratios calculated by the radio frequency codebook 1, the radio frequency codebook 2, the radio frequency codebook 3, the radio frequency codebook 4 and the radio frequency codebook 5 can be respectively 55dB, 70dB, 105dB, 90dB and 80dB, and then the maximum receiving signal-to-noise ratio for the mobile terminal A is 105 dB.
In the embodiment of the present invention, if the antenna sub-array 1 includes the radio frequency codebook 3 with a receiving signal-to-noise ratio of 105dB, the antenna sub-array 1 is determined as a target antenna sub-array.
And 206, pairing the target antenna sub-array with the target mobile terminal.
In the embodiment of the present invention, the antenna subarray 1 is paired with the mobile terminal a, so that data transmission is performed between the antenna subarray 1 and the mobile terminal a. Because the target mobile terminal is the mobile terminal which is not paired and the current throughput size requirement value is ranked first, the target antenna subarray which is not paired and enables the receiving signal-to-noise ratio of the target mobile terminal to be the maximum can be paired with the target mobile terminal in the unpaired mobile terminals, the target mobile terminal can conduct data transmission with the antenna subarray which has the maximum signal-to-noise ratio in the unpaired mobile terminal as far as possible, the transmission efficiency is improved, and the requirements of different mobile terminals on the throughput are met as far as possible.
Optionally, the step of obtaining the throughput size requirement value of each of the plurality of mobile terminals includes:
acquiring the number of resource blocks pre-configured for each mobile terminal;
and determining the number of resource blocks pre-configured for each mobile terminal as the throughput size requirement value of the mobile terminal.
In this embodiment, the more resource blocks allocated to a certain mobile terminal, the greater the throughput required by the mobile terminal, so the number of resource blocks used can be used to represent the throughput size requirement of the mobile terminal.
Optionally, the step of obtaining the throughput size requirement value of each of the plurality of mobile terminals includes:
receiving a data transmission request sent by each mobile terminal, wherein the data transmission request comprises the size value of a data packet to be transmitted of each mobile terminal;
and determining the size value of the data packet to be transmitted of each mobile terminal as the throughput size requirement value of each mobile terminal.
In this embodiment, the data transmission request may further include a data service requirement type, but the value of the throughput size requirement of a certain mobile terminal is determined, and only the value of the size of the data packet to be transmitted is needed. The larger the size value of the data packet to be transmitted is, the larger the throughput required by the mobile terminal is, so that the size value of the data packet to be transmitted can be used for representing the throughput size required value of the mobile terminal.
Optionally, the multiple antenna sub-arrays are represented by using the same matrix, different sub-vectors of the matrix are used for representing different antenna sub-arrays, and different elements in each sub-vector are used for representing different radio frequency codebooks in the sub-vectors.
In this embodiment, the plurality of antenna sub-arrays are represented by using the same matrix, so that the matrix operation can be conveniently performed on the plurality of antenna sub-arrays simultaneously, and thus, one antenna sub-array does not need to be independently calculated. The different sub-vectors of the matrix represent different antenna sub-arrays, and the sub-vectors can be row vectors or column vectors. And different elements in each sub-vector represent different radio frequency codebooks in the sub-vector, so that the matrix can also calculate a plurality of radio frequency codebooks simultaneously. For example, we can see the following matrix X (i.e., antenna array X).
Each row vector in the matrix represents an antenna subarray of the matrix, so that the antenna array has M antenna subarrays, and each antenna subarray has K radio frequency codebooks. Of course, X in the matrix may replace the success rate P or the signal-to-noise ratio SND to represent the power or the signal-to-noise ratio corresponding to each radio frequency codebook, so that the calculation of multiple radio frequency codebooks together may be facilitated.
The data transmission method of the embodiment of the invention obtains the throughput size requirement value of each mobile terminal in a plurality of mobile terminals; sequencing the throughput size requirement values of the mobile terminals according to a rule from large to small; according to the sequencing sequence, calculating the receiving signal-to-noise ratio of the target mobile terminal recorded by each radio frequency codebook from a plurality of antenna subarrays of the base station which are not paired according to the preset receiving power of the target mobile terminal recorded by each radio frequency codebook to obtain a plurality of receiving signal-to-noise ratios, wherein the target mobile terminal is the mobile terminal which is not paired and the current throughput value of which needs to be ranked first; determining the maximum received signal-to-noise ratio in the plurality of received signal-to-noise ratios obtained by calculation; determining an antenna sub-array containing a radio frequency codebook corresponding to the maximum receiving signal-to-noise ratio as the target antenna sub-array; and pairing the target antenna subarray with the target mobile terminal. Therefore, the target antenna subarray which enables the receiving signal-to-noise ratio of the target mobile terminal to be the maximum is selected to be paired with the target mobile terminal, and the data transmission efficiency is improved.
Referring to fig. 3, fig. 3 is a flowchart of another data transmission method according to an embodiment of the present invention, as shown in fig. 3, including the following steps:
In the embodiment of the invention, the target antenna subarray is the antenna subarray which enables the receiving signal-to-noise ratio of the mobile terminal to be maximum, so that the data transmission efficiency of the mobile terminal can be improved.
Optionally, before the step of performing data transmission between the mobile terminal and the target antenna sub-array in the base station, the method further includes:
and the mobile terminal sends a data transmission request to the base station, wherein the data transmission request comprises the size value of a data packet to be transmitted of the mobile terminal.
In this embodiment, the data transmission request may further include a data service requirement type, but the value of the throughput size requirement of a certain mobile terminal is determined, and only the value of the size of the data packet to be transmitted is needed. The larger the size value of the data packet to be transmitted is, the larger the throughput required by the mobile terminal is. Therefore, the base station can conveniently determine different antenna sub-arrays to send according to different requirements by sending the data transmission request comprising the size value of the data packet to be transmitted to the base station.
In the data transmission method of the embodiment of the invention, the mobile terminal and a target antenna sub-array in the base station perform data transmission, and the target antenna sub-array is an antenna sub-array which enables the receiving signal-to-noise ratio of the mobile terminal to be maximum. Therefore, the target antenna subarray which enables the receiving signal-to-noise ratio of the mobile terminal to be the maximum is selected to perform data transmission with the mobile terminal, and the data transmission efficiency is improved.
