Description

Technical Field

[0001] The present invention relates to the field of mobile communication technology, and in particular to a power distribution method, device and computer-readable storage medium. Background Art

[0002] In mobile communications, NR-FDD (NR: New Radio, New Wireless; FDD: Frequency Division Duplex) and LTE-FDD (LTE: Long Term Evolution) share spectrum. The spectrum-sharing sectors of NR-FDD and LTE-FDD include NR-FDD cells and LTE-FDD cells, and power allocation is usually required for NR-FDD cells and LTE-FDD cells. There are two main existing power allocation schemes: (1) Static spectrum sharing power allocation: NR-FDD cells and LTE-FDD cells share spectrum statically. NR-FDD cells and LTE-FDD cells each occupy different spectrum resources. There is no spectrum overlap at the same time. Power allocation also adopts a static power allocation scheme, and fixed power is allocated to NR-FDD cells and LTE-FDD cells respectively; (2) Dynamic power allocation according to spectrum ratio: NR-FDD cells and LTE-FDD cells share spectrum dynamically. NR-FDD cells and LTE-FDD cells occupy the same spectrum resources. There is full spectrum overlap at the same time. Power is allocated according to the spectrum allocation ratio of NR-FDD cells and LTE-FDD cells.

[0003] In the static spectrum sharing power allocation scheme, the small number of NR terminals in the early stages of 5G may lead to idle NR-FDD cell spectrum resources and incomplete utilization of NR-FDD cell power resources. The existing LTE-FDD cell spectrum resources may also be limited, resulting in increased 4G network load and insufficient power resources. In the dynamic power allocation scheme based on spectrum ratio, cells with large bandwidth demands do not necessarily require a large proportion of power resources. Similarly, cells with low bandwidth demands may require more power resources due to the remote location of users. Therefore, the bandwidth and power resource requirements of cells are not necessarily matched. Therefore, both the static spectrum sharing power allocation scheme and the dynamic power allocation scheme based on spectrum ratio do not allocate power rationally, resulting in low wireless throughput rates for users within the cell.

[0054] When the downlink instantaneous PRB utilization of the LTE-FDD cell is less than the first threshold, the available power of the LTE-FDD cell is adjusted to a second power, where the second power is less than a reference power of the LTE-FDD cell.

[0058] When the downlink instantaneous PRB utilization of the NR-FDD cell is greater than a third threshold, and the proportion of users using QPSK modulation in the downlink of the NR-FDD cell is greater than a third preset threshold, determining a third power according to the reference power of the NR-FDD cell, and adjusting the usable power of the NR-FDD cell to the third power, wherein the third power is greater than the reference power of the NR-FDD cell;

[0059] When the downlink instantaneous PRB utilization of the NR-FDD cell is less than the third threshold, the available power of the NR-FDD cell is adjusted to a fourth power, wherein the fourth power is less than the reference power of the NR-FDD cell.

[0061] When the downlink instantaneous PRB utilization of the NR-FDD cell is greater than the third threshold value, and the proportion of users using QPSK modulation in the downlink of the NR-FDD cell is greater than the third preset threshold, the power of the PDSCH of the NR-FDD cell is increased.

[0062] Based on the hardware architecture of the above power distribution device, an embodiment of the power distribution method of the present invention is proposed.

[0063] Reference Figure 2 , Figure 2 1 is a flow chart of a first embodiment of a power distribution method according to the present invention, wherein the power distribution method comprises:

[0064] Step S10, obtaining a downlink instantaneous physical resource module (PRB) utilization rate and a downlink user ratio using quadrature phase shift keying (QPSK) modulation of a target cell corresponding to the base station, wherein the target cell is a 5G new radio frequency division duplex (NR-FDD) cell and / or a long term evolution frequency division duplex (LTE-FDD) cell;

[0065] In the embodiment, the spectrum of NR-FDD and LTE-FDD in mobile communication is shared, and the spectrum sharing sector of NR-FDD and LTE-FDD includes NR-FDD cells and LTE-FDD cells. Generally, the available power of the NR-FDD cells and the LTE-FDD cells needs to be reasonably allocated to effectively utilize the power, especially the idle power, of the spectrum sharing sector. The NR-FDD cell refers to a sector that undertakes NR services in the spectrum sharing sector of NR-FDD and LTE-FDD, and the LTE-FDD cell refers to a sector that undertakes LTE services in the spectrum sharing sector of NR-FDD and LTE-FDD.

[0066] In the embodiment, the execution subject of the power allocation method is a power allocation device. The power allocation device refers to a device that can allocate and adjust the available power of the NR-FDD cells and the LTE-FDD cells. The power allocation device can be a base station, for example, at least one of an eNodeB base station and a gNodeB base station.

[0067] In the embodiment, the power allocation device acquires the downlink instantaneous PRB (Physical Resource Block) utilization rate and the proportion of users using QPSK (Quadrature Phase Shift Keying) modulation of a target cell corresponding to the base station. The target cell can be at least one of the NR-FDD cells and the LTE-FDD cells. The PRB utilization rate refers to the resource utilization rate of 12 continuous carriers in the frequency domain. The QPSK modulation is a modulation mode of a satellite digital signal, which has high spectrum utilization and strong anti-interference. The downlink instantaneous PRB utilization rate and the proportion of users using QPSK modulation can reflect the load conditions of the NR-FDD cells and the LTE-FDD cells, and thus the allocation of the power of the NR-FDD cells and the LTE-FDD cells can be determined according to the downlink instantaneous PRB utilization rate and the proportion of users using QPSK modulation.

[0068] Specifically, the power allocation device can acquire the downlink instantaneous PRB utilization rate and the proportion of users using QPSK modulation of the LTE-FDD cells at a certain time or in real time. The power allocation device can acquire the downlink instantaneous PRB utilization rate and the proportion of users using QPSK modulation of the NR-FDD cells at a certain time or in real time.

[0069] It should be noted that, since the current NR terminal is less and the LTE terminal is more, the power allocation device can preferentially acquire the downlink instantaneous PRB utilization ratio and the proportion of users using QPSK modulation of the LTE-FDD cell, and when the NR terminal is more and the LTE terminal is less, the power allocation device can also preferentially acquire the downlink instantaneous PRB utilization ratio and the proportion of users using QPSK modulation of the NR-FDD cell. The priority setting can be determined according to the layout of the NR terminal and the LTE terminal, which is not limited in the embodiment.

[0070] In step S20, the available power of the target cell is adjusted according to the downlink instantaneous PRB utilization ratio and the proportion of users using QPSK modulation of the target cell.

[0071] In the embodiment, after the power allocation device acquires the downlink instantaneous PRB utilization ratio and the proportion of users using QPSK modulation of the target cell, the available power of the target cell is adjusted according to the downlink instantaneous PRB utilization ratio and the proportion of users using QPSK modulation of the target cell. The available power refers to the power resource allocated to the LTE-FDD cell and / or the NR-FDD cell.

[0072] Specifically, after the power allocation device acquires the downlink instantaneous PRB utilization ratio and the proportion of users using QPSK modulation of the LTE-FDD cell, the available power of the LTE-FDD cell is adjusted according to the downlink instantaneous PRB utilization ratio and the proportion of users using QPSK modulation of the LTE-FDD cell. Generally, the greater the downlink instantaneous PRB utilization ratio of the LTE-FDD cell and the higher the proportion of users using QPSK modulation, the higher the load of the LTE-FDD cell, and the greater the power required to be allocated by the LTE-FDD cell, that is, when the downlink instantaneous PRB utilization ratio of the LTE-FDD cell is large and the proportion of users using QPSK modulation is high, the available power of the LTE-FDD cell is increased, otherwise, the available power of the LTE-FDD cell is reduced. After the power allocation device acquires the downlink instantaneous PRB utilization ratio and the proportion of users using QPSK modulation of the NR-FDD cell, the available power of the NR-FDD cell is adjusted according to the downlink instantaneous PRB utilization ratio and the proportion of users using QPSK modulation of the NR-FDD cell. Generally, the greater the downlink instantaneous PRB utilization ratio of the NR-FDD cell and the higher the proportion of users using QPSK modulation, the higher the load of the NR-FDD cell, and the greater the power required to be allocated by the NR-FDD cell, that is, when the downlink instantaneous PRB utilization ratio of the NR-FDD cell is large and the proportion of users using QPSK modulation is high, the available power of the NR-FDD cell is increased, otherwise, the available power of the NR-FDD cell is reduced.

[0073] In the technical solution provided in this embodiment, by obtaining the downlink instantaneous PRB utilization rate of the target cell corresponding to the base station and the proportion of users using QPSK modulation in the downlink, where the target cell is an NR-FDD cell and / or an LTE-FDD cell, the available power of the target cell is adjusted according to the downlink instantaneous PRB utilization rate of the target cell and the proportion of users using QPSK modulation in the downlink. This solution dynamically adjusts the power of the NR-FDD cell and / or the LTE-FDD cell based on the downlink instantaneous PRB utilization rate of the cell and the proportion of users using QPSK modulation in the downlink, so as to share the remaining power in the spectrum sharing sector with the cell with higher load, so that on the basis of the current background noise, the signal source power of the cell is increased to improve the carrier-to-interference ratio and increase the proportion of high-order modulation methods, thereby improving the wireless throughput rate of users in the cell.

[0074] Reference Figure 3 , Figure 3 2 is a flow chart of a second embodiment of the power distribution method of the present invention. Based on the first embodiment, the step S20 includes:

[0075] Step S21, obtaining the maximum power of the remote radio unit RRU or active antenna unit AAU corresponding to the base station;

[0076] In this embodiment, the power allocation device obtains the maximum power P of the RRU (Remote Radio Unit) or AAU (Active Antenna Unit) corresponding to the base station, where the RRU or AAU is the power hardware device of the base station and is used to provide power to the LTE-FDD cell and the NR-FDD cell. Optionally, the power allocation device can collect the maximum power P of the RRU / AAU in the physical sector where the NR-FDD and LTE-FDD spectrums are shared.

[0077] Specifically, the power allocation device can determine its maximum power P based on the specific model of the RRU or AAU, the power configuration of the LTE-FDD cell, and the NR-FDD cell. For example, if the NR-FDD cell adopts a 2W / MHz configuration, that is, each MHz is equipped with 2W of power, such as a cell with a 20MHz bandwidth is configured with a power of 20*2=40W, the LTE-FDD cell power configuration is the same as the NR-FDD cell; the power hardware device is an 8T8R RRU with a total of 8 channels, then its maximum power P=8*40W=320W.

[0078] Step S22, determining a reference power of the target cell according to the maximum power;

[0079] In this embodiment, after obtaining the maximum power P of the RRU or AAU, the power allocation device determines the reference power of the target cell according to the maximum power P.

[0080] Specifically, after obtaining the maximum power P of the RRU or AAU, the power allocation device can obtain the frequency band shared by LTE-FDD and NR-FDD, and determine the total power P0 available for the spectrum sharing sector of the LTE-FDD network and the NR-FDD network according to the frequency band shared by LTE-FDD and NR-FDD, and then determine the reference power of the LTE-FDD cell and the NR-FDD cell in the spectrum sharing sector of LTE-FDD and NR-FDD. The reference power of the LTE-FDD cell and the NR-FDD cell is determined as follows: the reference power P of the NR-FDD cell NR =P0*40%; LTE-FDD cell reference power P LTE =P0*40%.

[0081] It should be noted that the above-mentioned method of calculating the reference power is only an optional implementation method. In other embodiments, the reference power of the LTE-FDD cell and the NR-FDD cell can be set according to actual needs. This embodiment does not limit this. Generally, the sum of the reference powers of the LTE-FDD cell and the NR-FDD cell is less than the total power available in the spectrum sharing sector.

[0082] For example, if the 8T8R RRU supports frequency band n1 (uplink 1920MHz-1980MHz, downlink 2110MHz-2170MHz), frequency band n2 (uplink 1710MHz-1785MHz, downlink 1805MHz-1880MHz), the total power allocated to frequency band n1 is: 320W*50%=160W, and the frequency band shared by LTE-FDD and NR-FDD is n1, then the total power P0 that can be used by the spectrum sharing sector of LTE-FDD and NR-FDD is 160W, and then it can be obtained: the reference power P of the NR-FDD cell NR =P0*40%=64W; LTE-FDD cell reference power P LTE =P0*40%=64W.

[0083] Step S23: Adjust the available power of the target cell according to the reference power of the target cell, the downlink instantaneous PRB utilization rate, and the proportion of users using QPSK modulation in downlink.

[0084] In this embodiment, after determining the reference power of the target cell, the power allocation device adjusts the available power of the target cell according to the reference power of the target cell, the downlink instantaneous PRB utilization rate, and the proportion of users using QPSK modulation in the downlink.

[0085] In the technical solution provided in this embodiment, the maximum power of the RRU or AAU corresponding to the base station is obtained, the reference power of the target cell is determined according to the maximum power, and the available power of the target cell is adjusted according to the reference power of the target cell, the instantaneous downlink PRB utilization rate, and the proportion of users using QPSK modulation in the downlink. This solution dynamically adjusts the power of the NR-FDD cell and / or LTE-FDD cell based on the reference power of the target cell, the instantaneous downlink PRB utilization rate, and the proportion of users using QPSK modulation in the downlink, so as to share the remaining power in the spectrum sharing sector with the cell with higher load, so that on the basis of the current background noise, the signal source power of the cell is increased to improve the carrier-to-interference ratio, increase the proportion of high-order modulation methods, and thus improve the wireless throughput rate of users in the cell.

[0086] Reference Figure 4 , Figure 4 FIG. 5 is a flow chart of a third embodiment of the power distribution method of the present invention. Based on the second embodiment, the step S23 includes:

[0087] Step S24, obtaining the interval where the downlink instantaneous PRB utilization rate of the target cell is located and the interval where the proportion of users using downlink QPSK modulation is located;

[0088] Step S25 : adjusting the available power of the target cell according to the reference power of the target cell, the interval where the downlink instantaneous PRB utilization rate is located, and the interval where the proportion of users using downlink QPSK modulation is located.

[0089] In this embodiment, after the power allocation device obtains the reference power of the target cell, the downlink instantaneous PRB utilization rate, and the proportion of users using QPSK modulation in the downlink, it adjusts the available power of the target cell according to the interval of the downlink instantaneous PRB utilization rate of the target cell and the interval of the proportion of users using QPSK modulation in the downlink.
