Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

The embodiment of the present invention is applied to the Massive MIMO (multiple-inmultiple out) scenario during the evolution process from FDD (Frequency-division duplex) LTE (Long Term Evolution) to FDD NR (New Radio), and is aimed at user equipment, that is, static Beam scene.

Based on the multimedia data optimization processing method for a network set-top box according to the present invention, its embodiment will be described in detail below.

Step 101: Obtain the physical resource block utilization rate of the cell corresponding to the static beam of the antenna sector with a preset scale, determine the resource block number of the corresponding cell based on the physical resource block utilization rate, and set the corresponding resource block number for the cell according to the resource block number High priority resource block sequence.

In the embodiment of the present invention, the downlink physical resource block utilization rate of the static beam corresponding cell (that is, the local cell) in the six busy hour index periods of the preset scale antenna sector (that is, the Massive MIMO sector), that is, the downlink PRB (PhysicalResource Block) utilization rate; and calculate the number of resource blocks of the corresponding cell based on the utilization rate of the physical resource block, that is, calculate the number of RB (Resource Block) of the corresponding cell based on the load of the static beam corresponding to the cell; the static beam in the Massive MIMO sector corresponds to The cells alternately set the high-priority resource block sequence of each cell according to the calculated number of usable resource blocks, that is, the high-priority RB (Resource Block) sequence, which can reduce the number of local cells and neighboring cells (that is, neighboring cells) in the process of using services for users. The user equipments occupy the same frequency, thereby reducing the interference between cells. Through the six-busy PRB (physical resource block, physical resource block) utilization rate of the cell corresponding to the static beam of the MassiveMIMO sector, the number of RBs occupied by the cell can be calculated more accurately when the load is high, so as to set a high priority for the cell corresponding to the static beam Level RB sequence provides basis.

In the actual implementation process, the downlink physical resource block utilization rate of the cell corresponding to the static beam of the antenna sector with a preset scale in the six busy hour indicator period is obtained, specifically including:

Collect the downlink PRB utilization rate of the Massive MIMO static beam corresponding to the six busy hours of the cell.

The 2 sectors with the site ID of the base station are upgraded to Massive MIMO, and 4 static beams are configured. The cell IDs corresponding to the static beams are as follows: Beam-1(BRK8886L_75), Beam-2(BRK8886L_76), Beam-3(BRK8886L_77), Beam-4 (BRK8886L_78). And calculate the average PRB utilization rate of the six busy hours of the cell corresponding to the static beam, as shown in Table 1:

Table 1 The average downlink PRB utilization rate of Massive MIMO static beams corresponding to six busy hours of the cell

Further, calculate the corresponding RB quantity according to the mean value of the PRB utilization rate of the six busy hours of the cell corresponding to the static beam; according to the Massive MIMO sector configuration information, the sector uses Band 3 (1800MHz frequency band, uplink: 1710MHz-1785MHz; downlink: 1805MHz -1880MHz), the LTE bandwidth is 20MHz, and the number of available RBs is 100;

According to the PRB utilization rate during six busy hours, calculate the corresponding RB quantity, as shown in Table 2:

Table 2 Massive MIMO static beam corresponds to the number of RBs corresponding to the downlink PRB utilization rate of six busy cells

Furthermore, according to the calculated number of RBs, the high priority RB sequences of each cell are alternately set for the cells corresponding to the four static beams of the Massive MIMO sector. Specifically, the downlink PRB utilization rate of the six busy hours of the cell corresponding to the Massive MIMO static beam is calculated, and according to the cell bandwidth information, the number of RBs corresponding to the six busy hour PRB utilization rate of the cell corresponding to each static beam can be calculated; and then the Massive MIMO The four static beams of the sector correspond to the cells and alternately set the high-priority RB sequences of each cell. As shown in Figure 2: Beam-1, corresponding to the cell BRK8886L_75, set the high priority RB sequence as: RB1-45; Beam-2, corresponding to the cell BRK8886L_76, set the high priority RB sequence as: RB29-100; Beam-3, For cell BRK8886L_77, set the high priority RB sequence as: RB1-91; Beam-4, for cell BRK8886L_78, set the high priority RB sequence as: RB21-100.

Step 102: Acquiring the physical resource block utilization rate of the neighboring cell corresponding to the static beam, and determining and adjusting the number of allocated resource blocks based on the physical resource block utilization rate of the cell and the physical resource block utilization rate of the neighboring cell.

Specifically, first obtain the physical resource block utilization rate of the neighboring cell corresponding to the static beam, and determine whether the sum of the physical resource block utilization rate of the cell and the average value of the physical resource block utilization rate of the neighboring cell exceeds a preset target value; If not, determine the index value of the modulation and coding strategy corresponding to the user equipment, and adjust the number of allocated resource blocks according to the index value of the modulation and coding strategy and the buffer data size of the transport block.

For example, in a cell corresponding to a static beam, if the average PRB utilization rate of the cell and neighboring cells does not exceed 100%, determine the index value of the modulation and coding strategy corresponding to the user equipment, that is, the downlink MCS (Modulation and Coding Scheme) of the user equipment ) to improve the downlink MCS of the user equipment, so that the user equipment can obtain higher spectral efficiency, and improve the overall spectral efficiency of the Massive MIMO sector.

In the specific implementation process, the instantaneous downlink PRB utilization rate of the static beam cell and the neighboring cell corresponding to the static beam can be detected, that is, the instantaneous downlink PRB utilization rate of the cell corresponding to the static beam in the Massive MIMO scenario is monitored in real time on the monitoring platform. For example, for the BRK8886L_75 cell, the neighbor cells corresponding to its static beam are BRK8886L_76; for the BRK8886L_76 cell, the neighbor cells corresponding to its static beam are BRK8886L_75, BRK8886L_77; Cell, the neighbor cell corresponding to its static beam is BRK8886L_77. The sum of the instantaneous downlink PRB utilization ratios of the judging cell and the adjacent cell does not exceed 100%, specifically: for the BRK8886L_75 cell, the adjacent cell is BRK8886L_76, and it is judged whether the sum exceeds 100%; for the BRK8886L_76 cell, the adjacent cell is BRK8886L_75, For BRK8886L_77, first take the average value, and then judge that the sum of the cell and the adjacent cells does not exceed 100%; , the neighbor cell is BRK8886L_77, and judge whether its sum exceeds 100%. If it does not exceed 100%, determine the index value corresponding to the modulation and coding strategy of the user equipment to increase the index value of the downlink MCS of the user equipment, so that the user equipment can obtain higher spectral efficiency and improve the overall spectral efficiency of the Massive MIMO sector.

It should be noted that the sum of the instantaneous downlink PRB utilization ratios of the cell corresponding to the static beam of the Massive MIMO sector and the adjacent cells does not exceed 100%. Collision can improve the downlink MCS of the user equipment, enable the user equipment to obtain higher spectral efficiency, and improve the overall spectral efficiency of the MassiveMIMO sector. The 3GPP 36.213 agreement is clear: rely on the channel quality indicator CQI reported by the user equipment and the signal-to-interference ratio (Signal-to-Interference Ratio, SINR) to adjust the value of the MCS, and then adjust the buffered data size according to the MCS and the transport block (Transport Block Size, TBS) The number of allocated RBs. After the base station eNodeB obtains the index value of the MCS, it can obtain the number of PRBs that need to be allocated to the user equipment according to the TBS table and the size of the data to be transmitted; the use of a high-order MCS for the user equipment means more transmission block TBS, that is, a higher frequency spectrum Efficiency; different MCS levels represent different modulation methods and code rates, and the scheduling value range is [0,28], and 29, 30, and 31 are used for retransmission.

Further, in the specific implementation process, the horizontal azimuth and the horizontal azimuth angle of the static beam of the antenna sector with the preset scale can also be determined according to the utilization rate of the physical resource block of the cell and the utilization rate of the physical resource block of the adjacent cell. The beam width weight is used to control the number of user equipments accessing the cell corresponding to the static beam. Specifically, firstly, the physical active antenna module of the antenna sector of the preset size is adjusted according to the utilization rate of the physical resource block of the cell and the utilization rate of the physical resource block of the adjacent cell, so as to determine the predetermined size The horizontal azimuth angle and beam width weight corresponding to the static beam of the antenna sector.

In the actual implementation process, the physical active antenna module of the antenna sector of the preset size is adjusted according to the physical resource block utilization rate of the cell and the physical resource block utilization rate of the adjacent cell, so as to optimize the Massive MIMO sector The horizontal azimuth and beam width weight of the static beam under the zone control the access users of the cell corresponding to the static beam, and balance the PRB utilization rate of each cell. When one of the cells corresponding to the four static beams in the Massive MIMO scenario has a very high PRB utilization rate, it will increase the interference to neighboring cells. According to the collected PRB utilization rate data, the horizontal azimuth angle of the Massive MIMO antenna can be optimized and beamwidth weights. For example, before the Massive MIMO sector is replaced, the static beamwidth of the antenna is 65° (also known as the horizontal half-power angle of the antenna). After the Massive MIMO antenna is replaced, the static beamwidth of the overall sector changes from 65° to 90°. The beamwidths of the four static beams in the sector are 25°, 25°, 25°, and 25°. If adjustment in the horizontal direction is required, the active antenna module for the physical antenna of the Massive MIMO sector, that is, the AAU ( The ActiveAntenna Unit) unit is adjusted as a whole, and the horizontal direction angle of each static beam is also changed after adjustment, so as to control the access users of the cell corresponding to the static beam and balance the PRB utilization rate of each cell.

In addition, the downlink physical resource block utilization rate of the cell corresponding to the static beam of the preset scale antenna sector (that is, Massive MIMO) in the period of six busy hour indicators can be detected based on the preset time period, that is, the downlink PRB (PhysicalResource Block ) utilization rate, and determine the resource block quantity of the corresponding cell based on the physical resource block utilization rate, and repeatedly execute the above steps 102 and 103. It should be noted that the present invention is mainly aimed at the Massive MIMO static beam scenario during the evolution process from FDD LTE to FDD NR. Based on the load of the cell corresponding to the static beam, the number of corresponding RBs is calculated, and high priority is alternately set for the cell corresponding to the Massive MIMO static beam. The RB sequence, when the average PRB utilization rate of the cell and neighboring cells does not exceed 100%, improves the downlink MCS of the UE, enables the UE to obtain higher spectrum efficiency, and improves the overall spectrum efficiency of the Massive MIMO sector.

The communication resource allocation method provided by the embodiment of the present invention alternately sets high-priority RB sequences for the cells corresponding to the Massive MIMO static beams, which can reduce the frequency occupied by the cell and the user equipment in the neighboring cell during the service process of the user, thereby reducing the Inter-cell interference; through the six-busy-hour PRB utilization of the Massive MIMO static beam corresponding to the cell, the number of RBs occupied by the cell can be calculated more accurately when the load is higher, and provide a basis for setting high-priority RB sequences for the cell corresponding to the static beam; In the cell corresponding to the static beam, when the average PRB utilization rate of the local cell and neighboring cells does not exceed 100%, the downlink MCS of the user equipment is improved, so that the UE can obtain higher spectrum efficiency and improve the overall spectrum efficiency of the Massive MIMO sector.
