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.
Fig. 1 is a flowchart of a power coordination method according to an embodiment of the present invention, where a release execution subject according to the embodiment of the present invention is a base station, and as shown in fig. 1, the method according to the embodiment may include:
s101, receiving a measurement report sent by the terminal equipment.
Wherein the measurement report includes: the RSRP, the scheduling rate, the downlink transmission power, the MCS configuration information and the CSI of a serving cell of the terminal equipment, and the RSRP and the CSI of an adjacent cell.
In this embodiment, for each cell in all cells covered by the base station, the User Equipment (UE) periodically acquires RSRP, a scheduling rate, downlink transmission power, MCS configuration information, and CSI of a cell (i.e., a serving cell) in which the UE is located, and RSRP and CSI of an adjacent cell. And the scheduling rate is the data transmission rate sent to the UE by the base station according to the air interface quality.
And the UE of each cell sends the obtained RSRP, scheduling rate, downlink transmission power, MCS configuration information and CSI of the cell where the UE is located, and the RSRP and CSI of the adjacent cells to the base station in the form of measurement reports.
Optionally, the serving cell is any one of multiple cells, where the multiple cells are cells capable of performing inter-cell power coordination. In this embodiment, the network management system controls the base station, so that each cell covered by the base station is a cell capable of performing power coordination between cells.
S102, determining target downlink transmitting power of the terminal equipment according to the measurement report, the Physical Resource Block (PRB) utilization rates of the serving cell and the adjacent cell and the user rate of the terminal equipment.
In this embodiment, for each cell in all cells covered by the base station, for the same cell, the time points at which the user uses the UE in the cell are different, resulting in different times, the PRB utilization rate of the cell is not used, and for different cells, because the usage amount of the UE at the same time is different, the PRB utilization rate at the same time is different, so the UEs in the cells that are interfered by the neighboring cells at different times are different. Therefore, the base station needs to acquire the PRB utilization of each cell, its neighbor cells, and the user rate of each terminal device in each cell. Therefore, whether the downlink transmission power of the UE of the corresponding cell is adjusted or not is determined according to the PRB utilization rate of each cell.
And then, the base station determines the target downlink transmitting power of the terminal equipment according to the measurement report, the Physical Resource Block (PRB) utilization rates of the serving cell and the adjacent cell and the user rate of the terminal equipment. The Base station may be a distributed Base station, for example, and the target downlink transmission power of the terminal device may be specifically determined by a centralized control node in the Base station, where the centralized control node is disposed on a baseband processing unit (BBU).
Specifically, for a serving cell, the centralized control node determines, according to RSRP of the cell and RSRP of neighboring cells acquired by each UE in the cell, whether the UE is an edge UE of the cell, and whether downlink transmission power of the UE needs to be adjusted. For example, when the difference between the obtained RSRP of the cell and the obtained RSRP of the neighboring cell is within a preset range or the obtained RSRP of the neighboring cell is much larger than the obtained RSRP of the cell, it indicates that the UE is an edge UE and needs to adjust the downlink transmit power of the UE. Then, according to the scheduling rate of the UE, the downlink transmission power, the modulation and coding strategy MCS configuration information and the channel state information CSI of the downlink transmission power which needs to be adjusted, and the CSI of the adjacent cell, the target downlink transmission power of the UE is obtained.
S103, adjusting the downlink transmitting power of the terminal equipment according to a preset downlink scheduling algorithm and the target downlink transmitting power.
In this embodiment, since the centralized scheduling node determines that the number of UEs requiring adjustment of downlink transmission power in each period is multiple, and multiple UEs cannot use channel resources at the same time, after determining the target downlink transmission power of the UE requiring adjustment of downlink transmission power, the centralized scheduling node adjusts the downlink transmission power of the UE every TTI in combination with a preset downlink scheduling algorithm.
In this embodiment, a measurement report sent by a receiving terminal device is received, where the measurement report includes: reference Signal Received Power (RSRP), scheduling rate, downlink transmission power, Modulation and Coding Strategy (MCS) configuration information and Channel State Information (CSI) of a serving cell of the terminal equipment, and RSRP and CSI of an adjacent cell; determining target downlink transmitting power of the terminal equipment according to the measurement report, the Physical Resource Block (PRB) utilization rates of the serving cell and the adjacent cell and the user rate of the terminal equipment; and adjusting the downlink transmitting power of the terminal equipment according to a preset downlink scheduling algorithm and the target downlink transmitting power. Because the PRB utilization rate is related to the condition that the UE is used by the user in the cell, when the downlink transmission power is adjusted, the base station acquires the PRB utilization rate of each cell, the downlink transmission power of the UE in the cell can be coordinated from the time domain dimension, the signal-to-noise ratio of the edge UE is improved, and the interference between the cells is avoided.
Optionally, before S102, the power coordination method further includes: and acquiring the PRB utilization rate of each cell in the plurality of cells for multiple times in the first preset period according to a second preset period, wherein the second preset period is smaller than the first preset period.
Accordingly, one possible implementation manner of S102 is: determining a target downlink transmission power of a terminal device, comprising: and if the frequency that the PRB utilization rate of any cell is greater than the preset utilization rate is greater than the preset frequency, determining the target downlink transmitting power of the terminal equipment.
In this embodiment, for a cell capable of performing inter-cell power coordination, that is, a cell having a power coordination scheduling function turned on, the enabling state of the power coordination scheduling function is determined in real time according to the load degree, that is, whether to start downlink power coordination scheduling or stop downlink power coordination scheduling. In the embodiment of the present invention, a cluster is defined according to an area where a cell capable of performing inter-cell power coordination is located, and a plurality of base stations are included in the cluster. And synchronizing the power coordination scheduling function of each cell in the same cluster.
For each base station in a cluster, the base station divides the first preset period into a plurality of second preset periods, and obtains the PRB utilization rate of each cell according to the second preset periods, for example, as shown in fig. 2, the base station takes 15 minutes as the first preset period, and obtains the PRB utilization rate of each cell every 5 minutes in the first preset period, and may continuously obtain the PRB utilization rate of each cell for 3 times in 15 minutes.
The method comprises the steps that a base station acquires the PRB utilization rate of each cell in a first preset period, determines the maximum value of the PRB utilization rate according to the PRB utilization rate of each cell, compares the maximum value of the PRB utilization rate with the preset utilization rate, and starts downlink power coordinated scheduling for each cell under each base station in a cluster when the number of times that the maximum value of the PRB utilization rate is larger than the preset utilization rate in the first preset period is larger than the preset number of times, so that the target downlink transmitting power of UE is determined.
After the cell starts downlink power coordinated scheduling, if downlink power coordinated scheduling is performed on the cell which starts downlink power coordinated scheduling, the processing amount of the base station is increased, and the efficiency of the base station is reduced. Specifically, for example, as shown in fig. 2, for a cell where downlink power coordinated scheduling is started, a threshold of PRB utilization rate for stopping downlink power coordinated scheduling is set, each time a base station corresponding to the cell acquires the PRB utilization rate of each cell in a first preset period, a maximum value of PRB utilization rate is determined according to the PRB utilization rate of each cell, the maximum value of PRB utilization rate is compared with the set threshold of PRB utilization rate for stopping downlink power coordinated scheduling, when the maximum value of PRB utilization rate is less than 10% of the set threshold of PRB utilization rate for stopping downlink power coordinated scheduling, each cell in a cluster stops downlink power coordinated scheduling, so that when the PRB utilization rate of the cell is reduced, downlink power coordinated scheduling is stopped, and the throughput of the base station is reduced.
Optionally, the power coordination method further includes: and adjusting the MCS configuration information of the terminal equipment according to the adjusted downlink transmitting power of the terminal equipment.
In this embodiment, the downlink transmission power of each UE needs to be coordinated with the MCS configuration information, and when the adjusted downlink transmission power of the UE is increased, the MCS and the adjusted downlink transmission power of the UE need to be adjusted, so that the adjusted MCS can efficiently perform data transmission; when the adjusted UE downlink transmission power is reduced, the MCS and the adjusted UE downlink transmission power need to be used to ensure the reliability of data transmission.

As shown in fig. 3, the network architecture includes a UE, a base station, and a network management platform. The base station is a distributed base station, a baseband processing unit (BBU) and a radio frequency processing unit (RRU) are separated, and the centralized scheduling node is arranged on the BBU.

And the centralized scheduling node in the base station determines the target downlink transmission power of the UE according to the measurement report, the PRB utilization rate of each cell and the user rate of the terminal equipment. And, the centralized control node is divided into: centralized clustering nodes and centralized scheduling nodes, wherein the centralized clustering nodes perform a cell clustering function and map clusters to specific centralized scheduling node processes.
And the network management platform is used for configuring and monitoring power coordination, and a user can inquire the power configuration of each UE in any cell through the network management platform and obtain the gain of the UE after downlink transmission power adjustment, such as rate gain, flow gain, and the rate and flow gain of the whole cluster.
Optionally, for some application scenarios, for example, when a cell covered by the base station includes a hospital, a school, or a large exhibition and an important meeting exist in the covered area, the QCI in the area may be preconfigured according to actual requirements. Therefore, for areas with large exhibitions and important meetings in hospitals, schools or covered areas, for example, a UE differentiation strategy can be preset according to actual requirements, a feature library is established, and intelligent matching is achieved. And, the base station throughput is reduced.
