In order to better understand the technical solutions of the present invention, the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

It should be understood that the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. As used in the embodiments of the present invention and the appended claims, the singular forms "a," "the," and "the" are intended to include the plural forms as well, unless the context clearly dictates otherwise.

FIG. 1 shows a flowchart of a power coordination method according to an embodiment of the present invention.

As shown in FIG. 1 , the flow of the power coordination method according to an embodiment of the present invention includes:

Step 102: Detect downlink PRB (Physical Resource Block, physical resource block) utilization of all cells in the specified cluster.

Multiple base stations form a cluster, and one power coordination device can perform power coordination on a single cluster, or can perform power coordination on multiple clusters at the same time. PRB refers to a time slot (half subframe, 0.5ms) resource in the time domain. The higher the downlink PRB utilization rate of the cell, the more busy the communication behavior of the cell, the more downlink transmit power is required. The downlink transmit power of cells under different base stations is uniformly adjusted through the power coordination device.

Step 104, in response to that the downlink PRB utilization rate of any cell in the designated cluster is greater than or equal to a first predetermined threshold, start a power scheduling mode.

A first predetermined threshold value can be set, and the first predetermined threshold value is the lowest downlink PRB utilization rate that has reached the power coordination requirement. In this way, the downlink PRB utilization rate of all cells in the specified cluster can be detected. If the downlink PRB utilization rate of any cell is The PRB utilization rate is greater than or equal to the first predetermined threshold value, indicating that the downlink transmit power of the cell can no longer meet the actual traffic demand, and the power distribution in the cluster needs to be adjusted to allocate more downlink transmit power to the cell to avoid the cell Insufficient downlink transmit power leads to reduced traffic quality. Then, the downlink PRB utilization rate of any cell in the designated cluster is greater than or equal to the first predetermined threshold, and the power scheduling mode is started.

Step 106: In the power scheduling mode, send a user equipment monitoring instruction to the base station in the designated cluster, so that the base station can measure the user equipment communication information in the cell supported by the base station according to the user equipment monitoring instruction.

In the power scheduling mode, the cell power scheduling information of each cell under the base station can be calculated according to the user equipment communication information in each cell under the base station in the specified cluster, that is, the actual downlink transmit power required by each cell under the base station.

Step 108: Acquire the communication information of the user equipment from the base station.

Step 110: Calculate the cell power scheduling information of the base station according to the user equipment communication information.

In order to obtain user equipment communication information, a user equipment monitoring instruction can be sent to the base station in the designated cluster, so that the base station can measure the user equipment communication information in the cell supported by itself according to the user equipment monitoring instruction, and then measure the measured user equipment communication information. The user equipment communication information is sent to the power coordination device. According to the communication information of the user equipment in each cell, the actual load of each cell can be calculated, and then the matched downlink transmit power can be obtained according to the actual load of each cell.

Step 112: Send the cell power scheduling information to the base station, so that the base station configures downlink transmit power for the cell it supports according to the cell power scheduling information.

Finally, the cell power scheduling information is sent to the base station, and the base station configures downlink transmission power for each cell it supports according to the actual downlink transmission power required by each cell under the base station indicated in the cell power scheduling information.

Reduce inter-cell interference, improve channel quality and network performance, and enhance user online experience.

FIG. 2 shows a flowchart of a power coordination method according to another embodiment of the present invention.

As shown in FIG. 2, a flow of a power coordination method according to another embodiment of the present invention includes:

Step 202, in each predetermined detection period, perform a first predetermined number of detections on the downlink PRB utilization rates of all cells in the designated cluster.

It can cyclically detect whether downlink transmit power scheduling needs to be performed for each cell in the cluster. The predetermined detection period of this cycle can be any period automatically set according to the historical communication situation of the cluster or the communication importance level, and can be selected as 15min. While multiple base stations form a cluster, one power coordination device can perform power coordination on a single cluster, or can perform power coordination on multiple clusters at the same time. PRB refers to a time slot (half subframe, 0.5ms) resource in the time domain. The higher the downlink PRB utilization rate of the cell, the more busy the communication behavior of the cell, the more downlink transmit power is required. The downlink transmit power of cells under different base stations is uniformly adjusted through the power coordination device.

In the same predetermined detection period, detection can be performed every predetermined time interval, and the total amount of detection is a preset first predetermined number of times. The predetermined time interval and the first predetermined number of times can be based on the historical communication situation or communication importance level of the cluster. Any size set automatically, the predetermined time interval includes but not limited to 5min, and the first predetermined number of times includes but not limited to 3 times.

Step 204, in response to the detection of the downlink PRB utilization rate of any cell in the designated cluster in the first predetermined number of times, the number of times greater than or equal to the first predetermined threshold value reaches a second predetermined number of times, The power scheduling mode is activated.

The second predetermined number of times can be any size automatically set according to the historical communication situation of the cluster or the communication importance level, including but not limited to 3 times, and the first predetermined threshold value is the minimum downlink PRB utilization rate that has reached the power coordination requirement.

If the downlink PRB utilization rate of any cell in the designated cluster is greater than or equal to the first predetermined threshold in 3 detections of 5 min/time, it means that the number of PRBs in this cell is insufficient, and the actual downlink transmit power can no longer meet the actual communication requirements. , at this time, the power scheduling mode needs to be activated for each cell in the cluster, so as to further allocate reasonable downlink transmit power to each cell.

Step 206: In the power scheduling mode, send a user equipment monitoring instruction to the base station in the designated cluster, so that the base station can measure the user equipment communication information in the cell supported by the base station according to the user equipment monitoring instruction.

Step 208: Acquire the communication information of the user equipment from the base station.

Step 210: Calculate the actual load of each cell according to the communication information of the user equipment in each cell under the base station.

The user equipment communication information includes: RSRP (Reference Signal Receiving Power, reference signal received power) measurement information, MCS (Modulation and Coding Scheme, modulation and coding strategy) measurement information, cell RB (Resource Block, resource block) utilization rate and user rate. In the LTE network, RSRP can represent the wireless signal strength, which is the average value of the signal power received on all resource elements that carry the reference signal. The RS information can determine the actual transmit power of the cell under the base station, while the MCS measurement information represents the physical transmission. Rate, through RSRP measurement information, MCS measurement information, cell RB utilization rate and user rate, the total amount of resources that each cell under the base station actually needs to transmit in the time domain, that is, the actual load of each cell can be determined.

Step 212: According to the proportion of the actual load of each cell to the total load in the designated cluster, configure downlink transmit power of the proportion for each cell in the total amount of downlink transmit power.

The actual load of each cell is proportional to its required downlink transmit power. Therefore, the proportion of the actual load of each cell to the total load in the specified cluster can be calculated. Under ideal power distribution , this proportion is equivalent to the proportion of the downlink transmit power configured by each cell in the total downlink transmit power. Therefore, the downlink transmit power of this proportion can be configured for each cell in the total downlink transmit power, as the final With the cell power scheduling information, the downlink transmit power of each cell can be adapted to its actual communication requirements.

Step 214: Send the cell power scheduling information to the base station, so that the base station configures downlink transmit power for the cell it supports according to the cell power scheduling information.

Finally, the cell power scheduling information is sent to the base station, and the base station configures the downlink transmission power for each cell it supports according to the actual downlink transmission power required by each cell under the base station indicated in the cell power scheduling information, that is, the power coordination device The power is re-divided, and the base station is the main body that allocates different power to each cell according to the division result.

Through the above technical solutions, the downlink transmit power of each cell can be reasonably adjusted and redistributed in the time domain for the downlink channel according to the actual communication requirements of the user equipment in each cell, which can maximally adapt to the actual communication requirements. Reduce inter-cell interference, improve channel quality and network performance, and enhance user online experience.

In the embodiments shown in FIG. 1 and FIG. 2 , optionally, it further includes: in the power scheduling mode, in response to the downlink PRB utilization rate of all cells in the designated cluster being less than a second predetermined threshold value, exit the power scheduling mode.

That is to say, the second predetermined threshold value is the minimum downlink PRB utilization rate that exceeds the actual communication capability of the cell. If the downlink PRB utilization rate of all cells in the designated cluster is lower than the second predetermined threshold value, it means that all the cells in the designated cluster have the lowest downlink PRB utilization rate. None of the cells are overloaded with communication and have reasonable downlink transmit power, so there is no need for power coordination, and the power scheduling mode can be exited.

The ratio of the second predetermined threshold value to the first predetermined threshold value is a predetermined percentage, and the predetermined percentage is less than 1. The predetermined percentage can be set to any value that meets the actual communication needs, and can be selected as 0.9.

Further, in another implementation manner of the present invention, in response to the third predetermined number of times of detection of the downlink PRB utilization rate of all cells in the designated cluster, the number of times is less than the second predetermined threshold value. When the fourth predetermined number of times is reached, the power scheduling mode is exited.

That is to say, in order to ensure that the power scheduling mode is exited when all cells are not overloaded with communication, the downlink PRB utilization rate of all cells in the specified cluster can be detected for a third predetermined number of times. Among the predetermined times, there is a fourth predetermined number of times that the downlink PRB utilization rates of all cells in the designated cluster are less than the second predetermined threshold, then it is considered that all cells in the designated cluster are at a relatively stable and reasonable downlink transmit power level, then The power scheduling mode may be exited.

The third predetermined number of times and the fourth predetermined number of times can be set according to actual communication requirements, the third predetermined number of times can be selected as 3 times, and the fourth predetermined number of times can be selected as 3 times.

FIG. 3 shows a flowchart of a power coordination method according to yet another embodiment of the present invention.

As shown in FIG. 3 , the flow of the power coordination method according to still another embodiment of the present invention includes:

Step 302: Obtain a user equipment monitoring instruction from a power coordination device in a power scheduling mode.

Step 304: According to the user equipment monitoring instruction, send a communication information collection instruction to each user equipment in the cell supported by the base station, so that each user equipment can upload the user equipment communication information to the user equipment according to the communication information collection instruction. the base station.

In order to obtain user equipment communication information, a user equipment monitoring instruction can be sent to the base station in the designated cluster, so that the base station can measure the user equipment communication information in the cell supported by itself according to the user equipment monitoring instruction, and then measure the measured user equipment communication information. The user equipment communication information is sent to the power coordination device.

Step 306: Acquire the user equipment communication information from each user equipment.

Step 308: Send the user equipment communication information to the power coordination device, so that the power coordination device can calculate the cell power scheduling information of the base station according to the user equipment communication information.

The power coordination device can calculate the actual load of each cell according to the communication information of the user equipment in each cell, and then can obtain the matched downlink transmit power according to the actual load of each cell.

Step 310: Receive the cell power scheduling information from the power coordination device.

Step 312: Configure downlink transmit power for the cell supported by the base station according to the cell power scheduling information.

Finally, the cell power scheduling information is sent to the base station, and the base station configures the downlink transmission power for each cell it supports according to the actual downlink transmission power required by each cell under the base station indicated in the cell power scheduling information, that is, the power coordination device The power is re-divided, and the base station is the main body that allocates different power to each cell according to the division result.

Through the above technical solutions, the downlink transmit power of each cell can be reasonably adjusted and redistributed in the time domain for the downlink channel according to the actual communication requirements of the user equipment in each cell, which can maximally adapt to the actual communication requirements. Reduce inter-cell interference, improve channel quality and network performance, and enhance user online experience.
