Detailed Description
In order to make the objects, 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 with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention is applied to Massive MIMO (multiple-in multiple out) scenes in the process of FDD (Frequency-division duplex) LTE (Long Term Evolution) to FDD NR (New Radio), and aims at user equipment, namely static beam scenes with large proportion of user equipment.
The following describes an embodiment of the method for optimizing multimedia data for a network set top box according to the present invention in detail.
Step 101: the method comprises the steps of obtaining the utilization rate of physical resource blocks of a cell corresponding to a static wave beam of a preset scale antenna sector, determining the number of the resource blocks of the corresponding cell based on the utilization rate of the physical resource blocks, and setting a corresponding high-priority resource block sequence for the cell according to the number of the resource blocks.
In the embodiment of the invention, the utilization rate of a downlink Physical Resource Block (PRB) of a cell (local cell) corresponding to a static wave beam of a preset scale antenna sector (Massive MIMO sector) in a six-busy hour index period is obtained; calculating the number of Resource blocks of the corresponding cell based on the utilization rate of the physical Resource blocks, namely calculating the number of RBs (Resource blocks) of the corresponding cell based on the load of the cell corresponding to the static wave beams; high-priority Resource Block sequences, namely high-priority RB (Resource Block) sequences, of all the cells are alternately arranged in the cells corresponding to the static wave beams of the Massive MIMO sector according to the number of the usable Resource blocks obtained through calculation, so that the situation that user equipment of a local cell and user equipment of an adjacent cell (namely the adjacent cell) occupy the same frequency in the service using process of a user can be reduced, and the interference among the cells is reduced. The number of RBs occupied by a cell under a higher load can be calculated more accurately by the utilization rate of Physical Resource Blocks (PRBs) of the cell corresponding to the static beam of the Massive MIMO sector, so that a basis is provided for setting a high-priority RB sequence for the cell corresponding to the static beam.
In the actual implementation process, the method for acquiring the utilization rate of the downlink physical resource block of the cell corresponding to the static beam of the preset-scale antenna sector in the index period of six busy hours specifically comprises the following steps:
and acquiring the utilization rate of the downlink PRB when the Massive MIMO static wave beam corresponds to six busy cells.
2 sectors with base station Site ID of 8886 are upgraded to Massive MIMO, and 4 static beams are configured, wherein the cell ID corresponding to the static beams is as follows: beam-1 (BRK 8886L _ 75), beam-2 (BRK 8886L _ 76), beam-3 (BRK 8886L _ 77), beam-4 (BRK 8886L _ 78). And calculating the average value of the PRB utilization rate of the static wave beam corresponding to the cell in six busy hours, as shown in table 1:
table 1 mean downlink PRB utilization rate when Massive MIMO static wave beam corresponds to six busy hours of cell
Further, calculating the corresponding RB quantity according to the average value of the PRB utilization rate of the cells corresponding to the static wave beams in the six busy hours; according to the Massive MIMO sector configuration information, the sector uses Band 3 (1800 MHz frequency Band, uplink: 1710MHz-1785MHz; downlink: 1805MHz-1880 MHz), the LTE bandwidth is 20MHz, and the number of usable RBs is 100;
calculating the corresponding RB quantity according to the PRB utilization rate in six busy hours, as shown in Table 2:
table 2 RB number corresponding to downlink PRB utilization rate when Massive MIMO static wave beam corresponds to cell six busy
Furthermore, according to the calculated number of RBs, high-priority RB sequences of each cell are alternately arranged for the cells corresponding to the 4 static beams of the Massive MIMO sector. Specifically, the utilization rate of the downlink PRB in six busy hours of the cell corresponding to the Massive MIMO static wave beams is obtained through calculation, and the number of RBs corresponding to the utilization rate of the PRB in six busy hours of the cell corresponding to each static wave beam can be obtained through calculation according to the cell bandwidth information; and further alternately setting high-priority RB sequences of each cell for the cells corresponding to the 4 static beams of the Massive MIMO sector. As shown in fig. 2: beam-1, corresponding to cell BRK8886L _75, sets the high priority RB sequence as: RB1-45; beam-2, corresponding to the cell BRK8886L _76, sets the high priority RB sequence as: RB29-100; and Beam-3, corresponding to the cell BRK8886L _77, setting the high-priority RB sequence as follows: RB1-91; beam-4, corresponding to cell BRK8886L _78, sets the high priority RB sequence as: RB21-100.
Step 102: and acquiring the utilization rate of the physical resource block of the adjacent cell corresponding to the static wave beam, and determining the quantity of the resource blocks which are adjusted and distributed based on the utilization rate of the physical resource block of the cell and the utilization rate of the physical resource block of the adjacent cell.
Specifically, the physical resource block utilization rate of the neighboring cell corresponding to the static beam is obtained first, and whether the sum of the physical resource block utilization rate of the cell and the mean value of the physical resource block utilization rates of the neighboring cells exceeds a preset target value is judged; if not, determining the index value of the modulation coding strategy corresponding to the user equipment, and adjusting the quantity of the allocated resource blocks according to the index value of the modulation coding strategy and the size of the transmission block cache data.
For example, in a cell corresponding to a static beam, when the average PRB utilization rate of the cell and a neighboring cell does not exceed 100%, an index value of a Modulation and Coding strategy corresponding to a ue, that is, an index value of a downlink MCS (Modulation and Coding Scheme) of the ue is determined, so as to improve the downlink MCS of the ue, enable the ue to obtain higher spectral efficiency, and improve the overall spectral efficiency of a Massive MIMO sector.
In a 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 a Massive MIMO scene is monitored in real time by the monitoring platform. For example, for a BRK8886L _75 cell, the neighbor cell corresponding to the static beam is BRK8886L _76; for the BRK8886L _76 cell, the neighbor cells corresponding to the static beams are BRK8886L _75 and BRK8886L _77; for the BRK8886L _77 cell, the neighbor cells corresponding to the static beams are BRK8886L _76 and BRK8886L _78; for the BRK8886L _78 cell, the neighbor cell corresponding to the static beam is BRK8886L _77. The method for judging the average value of the instantaneous downlink PRB utilization rates of the cell and the adjacent cell is not more than 100 percent, and specifically comprises the following steps: for the BRK8886L _75 cell, the adjacent cell is BRK8886L _76, and whether the sum of the BRK8886L _76 and the adjacent cell exceeds 100% is judged; for the BRK8886L _76 cell, the adjacent cells are BRK8886L _75 and BRK8886L _77, the average value is firstly taken, and then the sum of the cell and the adjacent cells is judged to be not more than 100 percent; for the BRK8886L _77 cell, the adjacent cells are BRK8886L _76 and BRK8886L _78, the average value is firstly taken, and then the sum of the cell and the adjacent cells is judged to be not more than 100 percent; for the BRK8886L _78 cell, the neighbor cell is BRK8886L _77, and it is determined whether the sum of the BRK8886L _77 cells exceeds 100%. If the index value does not exceed 100%, determining the index value of the modulation and coding strategy corresponding to the user equipment so as to improve the index value of the downlink MCS of the user equipment, so that the user equipment obtains higher frequency spectrum efficiency, and the overall frequency spectrum efficiency of the Massive MIMO sector is improved.
It should be noted that, the sum of the instantaneous downlink PRB utilization averages of the cell and the neighboring cell corresponding to the static beam of the Massive MIMO sector is not more than 100%, even if a cell reference signal detects a high overlapping coverage rate, since a traffic channel is not collided, the downlink MCS of the user equipment can be improved, so that the user equipment obtains a higher spectrum efficiency, and the overall spectrum efficiency of the Massive MIMO sector is improved. The 3gpp 36.213 protocol is explicit: the value of MCS is adjusted by means of the channel quality indicator CQI and the Signal-to-Interference Ratio (SINR) reported by the user equipment, and then the allocated RB quantity is adjusted according to the MCS and the Size of the buffer data of the Transport Block Size (TBS). After the base station eNodeB obtains the index value of the MCS, the PRB number needing to be allocated to the user equipment can be obtained according to the TBS table and the size of the data to be transmitted; the use of a higher order MCS by the user equipment means more transport blocks, TBS, i.e. higher spectral efficiency; different MCS levels represent different modulation modes and code rates, and scheduling value ranges [0,28],29, 30 and 31 are used for retransmission.
Further, in a specific implementation process, the horizontal azimuth and the beam width weight of the static beam of the preset-scale antenna sector may be determined according to the physical resource block utilization rate of the cell and the physical resource block utilization rate of the neighboring cell, so as to control the number of access ues of the cell corresponding to the static beam. Specifically, the physical active antenna module of the preset-scale antenna sector is adjusted according to the physical resource block utilization rate of the cell and the physical resource block utilization rate of the neighboring cell, so as to determine a horizontal azimuth angle and a beam width weight corresponding to a static beam of the preset-scale antenna sector.
In the actual implementation process, the physical active antenna module of the preset-scale antenna sector is adjusted according to the physical resource block utilization rate of the cell and the physical resource block utilization rate of the neighboring cell, so as to optimize the horizontal azimuth angle and the beam width weight of the static beam in the Massive MIMO sector, control the access user of the cell corresponding to the static beam, and balance the PRB utilization rate of each cell. When the PRB utilization rate of one cell is very high in the cells corresponding to the 4 static beams of the Massive MIMO scene, the interference to the adjacent cell is increased, and the horizontal azimuth angle and the beam width weight of the Massive MIMO antenna can be optimized according to the acquired PRB utilization rate data. For example, if the static beam width of the Antenna before the replacement of the Massive MIMO sector is 65 ° (also referred to as an Antenna horizontal half-power angle), after the replacement of the Massive MIMO Antenna, the static beam width of the entire sector is changed from 65 ° to 90 °, the beam widths of 4 static beams in the sector are 25 °,25 °,25 °, and 25 °, if adjustment in the horizontal direction is required, the whole adjustment is performed on the physical Antenna Active Antenna module of the Massive MIMO sector, that is, an AAU (Active Antenna Unit) Unit, and the horizontal direction angle of each static beam after the adjustment is also changed accordingly, thereby controlling access users of cells corresponding to the static beams and balancing the PRB utilization rate of each cell.
In addition, the utilization rate of a downlink Physical Resource Block (PRB) in an index period of six busy hours of a cell corresponding to a static beam of a preset-scale antenna sector (i.e., massive MIMO) may be detected based on a preset time period, the number of Resource blocks of the corresponding cell is determined based on the utilization rate of the Physical Resource Block, and the above steps 102 and 103 are repeatedly performed. It should be noted that, the invention mainly aims at the load of the corresponding cell of the static beam in the Massive MIMO static beam scene in the evolution process from FDD LTE to FDD NR, calculates the number of corresponding RBs, alternately sets high-priority RB sequences for the corresponding cell of the Massive MIMO static beam, and improves the downlink MCS of the UE under the condition that the average PRB utilization rate of the cell and the neighboring cell does not exceed 100%, so that the UE obtains higher spectrum efficiency, and improves the overall spectrum efficiency of the Massive MIMO sector.
According to the communication resource allocation method provided by the embodiment of the invention, the high-priority RB sequences are alternately arranged for the cells corresponding to the Massive MIMO static wave beams, so that the frequency occupied by the user equipment of the cells and the user equipment of the adjacent cells in the service using process of the user can be reduced, and the interference among the cells is reduced; the number of RBs occupied by the cell under higher load can be calculated more accurately through the utilization rate of the PRBs in the six busy hours of the cell corresponding to the Massive MIMO static wave beams, and a basis is provided for setting a high-priority RB sequence for the cell corresponding to the static wave beams; in the cell corresponding to the static wave beam, under the condition that the average PRB utilization rate of the local cell and the adjacent cell is not more than 100%, the downlink MCS of the user equipment is improved, the UE obtains higher frequency spectrum efficiency, and the overall frequency spectrum efficiency of the Massive MIMO sector is improved.
