图1为本发明一实施例提供的功率协调方法的流程图，本发明实施例放任执行主体为基站，如图1所示，本实施例的方法可以包括：Fig. 1 is a flowchart of a power coordination method provided by an embodiment of the present invention. In the embodiment of the present invention, the execution subject is allowed to be a base station. As shown in Fig. 1, the method of this embodiment may include:
S101、接收终端设备发送的测量报告。S101. Receive a measurement report sent by a terminal device.
其中，测量报告包括：终端设备的服务小区的RSRP、调度速率、下行发射功率、MCS配置信息和CSI，以及邻小区的RSRP和CSI。Wherein, the measurement report includes: RSRP, scheduling rate, downlink transmission power, MCS configuration information and CSI of the serving cell of the terminal device, and RSRP and CSI of neighboring cells.
本实施例中，对于基站所覆盖的所有小区中的每个小区，该用户设备(UserEquipment，UE)周期性获取自身所在的小区(即服务小区)的RSRP、调度速率、下行发射功率、MCS配置信息和CSI，以及邻小区的RSRP和CSI。其中，调度速率为基站根据空口质量发送给UE的数据传输速率。In this embodiment, for each cell in all the cells covered by the base station, the user equipment (UserEquipment, UE) periodically obtains the RSRP, scheduling rate, downlink transmission power, and MCS configuration of the cell where it is located (ie, the serving cell). Information and CSI, as well as RSRP and CSI of neighboring cells. Wherein, the scheduling rate is the data transmission rate sent by the base station to the UE according to the air interface quality.
每个小区的UE将获得的其所在小区的RSRP、调度速率、下行发射功率、MCS配置信息和CSI，以及邻小区的RSRP和CSI以测量报告的形式发送给基站。The UE in each cell sends the obtained RSRP, scheduling rate, downlink transmit power, MCS configuration information and CSI of the cell where it is located, as well as the RSRP and CSI of neighboring cells to the base station in the form of measurement reports.
可选的，服务小区为多个小区中的任一个小区，其中，多个小区为可进行小区间功率协调的小区。本实施例中，通过网络管理系统控制基站，使基站覆盖的每个小区为可进行小区间功率协调的小区。Optionally, the serving cell is any one of multiple cells, where the multiple cells are cells that can perform inter-cell power coordination. In this embodiment, the base station is controlled by the network management system, so that each cell covered by the base station is a cell that can perform inter-cell power coordination.
S102、根据测量报告、服务小区及邻小区的物理资源块PRB利用率和终端设备的用户速率，确定终端设备的目标下行发射功率。S102. Determine the target downlink transmit power of the terminal device according to the measurement report, the PRB utilization ratio of the serving cell and the adjacent cell, and the user rate of the terminal device.
本实施例中，对于基站所覆盖的所有小区中的每个小区，对于同一个小区，该小区中用户使用UE的时间点不同，导致不同时刻，该小区的PRB利用率不用，以及不同的小区，由于同一时刻UE的使用量不同使得在同一时刻PRB利用率，因此，不同的时刻受到邻区干扰的小区中的UE不同。因此，基站需要获取每个小区、其邻小区的PRB利用率以及每个小区中每个终端设备的用户速率。从而根据每个小区的PRB利用率确定是否对相应小区的UE的下行发射功率进行调整。In this embodiment, for each cell in all the cells covered by the base station, for the same cell, the time points at which users use UEs in the cell are different, resulting in different PRB utilization rates of the cell at different times, and different cells , due to the different usage of UEs at the same time, the PRB utilization rate at the same time, therefore, the UEs in the cell interfered by the neighboring cells are different at different times. Therefore, the base station needs to acquire the PRB utilization ratios of each cell and its neighboring cells, and the user rate of each terminal device in each cell. Therefore, it is determined whether to adjust the downlink transmit power of the UE in the corresponding cell according to the PRB utilization rate of each cell.
然后，基站根据测量报告、服务小区及邻小区的物理资源块PRB利用率和终端设备的用户速率，确定终端设备的目标下行发射功率。其中，基站例如可以是分布式基站，则终端设备的目标下行发射功率具体的可由基站中的集中控制节点确定，集中控制节点设置在基带处理单元(Building Base band Unite，BBU)上。Then, the base station determines the target downlink transmit power of the terminal device according to the measurement report, the PRB utilization rate of the serving cell and the adjacent cell, and the user rate of the terminal device. Wherein, the base station may be, for example, a distributed base station, and the target downlink transmission power of the terminal device may be specifically determined by a centralized control node in the base station, and the centralized control node is set on a baseband processing unit (Building Base band Unit, BBU).
具体的，针对一个服务小区，集中控制节点根据该小区中每个UE获取到的该小区的RSRP以及邻小区的RSRP，判断该UE是否为该小区的边缘UE，以及是否需要对该UE的下行发射功率进行调整。例如，当该UE获取到的该小区的RSRP与获取到的邻小区的RSRP之间的差值在预设范围内或者获取到的邻小区的RSRP远远大于获取到的该小区的RSRP时，说明该UE为边缘UE且需要对该UE的下行发射功率进行调整。然后，根据需要调整下行发射功率的UE的调度速率、下行发射功率、调制与编码策略MCS配置信息和信道状态信息CSI，以及邻小区的CSI，获取UE的目标下行发射功率。Specifically, for a serving cell, the centralized control node judges whether the UE is an edge UE of the cell according to the RSRP of the cell obtained by each UE in the cell and the RSRP of the neighboring cell, and whether downlink to the UE is required. Adjust the transmit power. For example, when the difference between the RSRP of the cell obtained by the UE and the RSRP of the neighboring cell obtained by the UE is within a preset range or the obtained RSRP of the neighboring cell is much greater than the obtained RSRP of the cell, It indicates that the UE is an edge UE and the downlink transmit power of the UE needs to be adjusted. Then, according to the scheduling rate, downlink transmission power, modulation and coding strategy MCS configuration information and channel state information CSI of the UE that needs to adjust the downlink transmission power, and the CSI of the neighboring cell, the target downlink transmission power of the UE is obtained.
S103、根据预设下行调度算法和目标下行发射功率，调整终端设备的下行发射功率。S103. Adjust the downlink transmission power of the terminal device according to the preset downlink scheduling algorithm and the target downlink transmission power.
本实施例中，由于集中调度节点在每个周期内确定的需要调整下行发射功率的UE的数量为多个，而多个UE无法同时使用信道资源，因此，在确定需要调整下行发射功率的UE的目标下行发射功率后，结合预设下行调度算法，每TTI调整UE的下行发射功率。In this embodiment, since the number of UEs that need to adjust the downlink transmission power determined by the centralized scheduling node in each period is multiple, and multiple UEs cannot use channel resources at the same time, when determining the UEs that need to adjust the downlink transmission power After the target downlink transmit power is set, the downlink transmit power of the UE is adjusted every TTI in combination with the preset downlink scheduling algorithm.
本实施例，通过接收终端设备发送的测量报告，其中，测量报告包括：终端设备的服务小区的参考信号接收功率RSRP、调度速率、下行发射功率、调制与编码策略MCS配置信息和信道状态信息CSI，以及邻小区的RSRP和CSI；根据测量报告、服务小区及邻小区的物理资源块PRB利用率和终端设备的用户速率，确定终端设备的目标下行发射功率；根据预设下行调度算法和目标下行发射功率，调整终端设备的下行发射功率。由于PRB利用率与小区内用户使用UE的情况有关，在进行下行发射功率调整时，基站采集每个小区的PRB利用率，可以从时域维度对小区中UE的下行发射功率进行协调，提升边缘UE的信噪比，避免小区间的干扰。In this embodiment, by receiving the measurement report sent by the terminal device, the measurement report includes: the reference signal received power RSRP of the serving cell of the terminal device, scheduling rate, downlink transmission power, modulation and coding strategy MCS configuration information and channel state information CSI , and the RSRP and CSI of the adjacent cell; according to the measurement report, the PRB utilization rate of the physical resource block of the serving cell and the adjacent cell, and the user rate of the terminal device, determine the target downlink transmit power of the terminal device; according to the preset downlink scheduling algorithm and the target downlink Transmit power, adjust the downlink transmit power of the terminal device. Since the PRB utilization rate is related to the usage of UEs in the cell, when adjusting the downlink transmission power, the base station collects the PRB utilization rate of each cell, and can coordinate the downlink transmission power of UEs in the cell from the time domain dimension to improve the edge Signal-to-noise ratio of the UE to avoid inter-cell interference.
可选的，在S102之前，功率协调方法还包括：根据第二预设周期，在第一预设周期内多次获取多个小区中每个小区的PRB利用率，第二预设周期小于第一预设周期。Optionally, before S102, the power coordination method further includes: according to the second preset period, acquiring the PRB utilization rate of each cell in the plurality of cells multiple times in the first preset period, and the second preset period is shorter than the second preset period a preset period.
相应的，S102的一种可能的实现方式为：确定终端设备的目标下行发射功率，包括：若任一小区的PRB利用率大于预设利用率的次数大于预设次数，则确定终端设备的目标下行发射功率。Correspondingly, a possible implementation of S102 is: determining the target downlink transmission power of the terminal device, including: if the number of times the PRB utilization rate of any cell is greater than the preset utilization rate is greater than the preset number of times, then determining the target power of the terminal device Downlink transmit power.
本实施例中，对于可进行小区间功率协调的小区，即开通功率协调调度功能的小区，实时根据负载程度判断功率协调调度功能的使能状态，即是否开启下行功率协调调度或停止下行功率协调调度。其中，本发明实施例中，根据可进行小区间功率协调的小区所在的区域，定义一个簇，在一个簇内，包括多个基站。在同一个簇内的每个小区的功率协调调度功能同步。In this embodiment, for cells that can perform inter-cell power coordination, that is, cells that enable the power coordination and scheduling function, the enabling status of the power coordination and scheduling function is judged in real time according to the load level, that is, whether to enable downlink power coordination and scheduling or stop downlink power coordination. scheduling. Wherein, in the embodiment of the present invention, a cluster is defined according to the area where the cells that can perform inter-cell power coordination are located, and a cluster includes multiple base stations. The power coordination and scheduling functions of each cell in the same cluster are synchronized.
对于一个簇内的每个基站，基站将第一预设周期划分为多个第二预设周期，根据第二预设周期获取每个小区的PRB利用率，例如，如图2所示，基站以15分钟为第一预设周期，在第一预设周期内，每5分钟获取每个小区的PRB利用率，在15分钟内可以连续获取3次每个小区的PRB利用率。For each base station in a cluster, the base station divides the first preset period into multiple second preset periods, and obtains the PRB utilization rate of each cell according to the second preset period. For example, as shown in FIG. 2, the base station Taking 15 minutes as the first preset period, within the first preset period, the PRB utilization rate of each cell is obtained every 5 minutes, and the PRB utilization rate of each cell can be continuously obtained 3 times within 15 minutes.
基站在第一预设周期内每获取到每个小区的PRB利用率，根据每个小区的PRB利用率确定出PRB利用率最大值，将PRB利用率最大值与预设利用率进行比较，当在第一预设周期内，PRB利用率最大值大于预设利用率的次数大于预设次数时，对簇内的每个基站下的每个小区开启下行功率协调调度，从而确定UE的目标下行发射功率。Each time the base station obtains the PRB utilization rate of each cell in the first preset period, it determines the maximum value of the PRB utilization rate according to the PRB utilization rate of each cell, and compares the maximum value of the PRB utilization rate with the preset utilization rate. When In the first preset period, when the number of times the maximum value of the PRB utilization rate is greater than the preset utilization rate is greater than the preset number of times, start downlink power coordinated scheduling for each cell under each base station in the cluster, so as to determine the target downlink of the UE transmit power.
在小区开启下行功率协调调度后，如果对开启下行功率协调调度的小区进行下行功率协调调度，会增加基站的处理量，减少基站效率，因此，需要使开启下行功率协调调度的小区停止进行下行功率协调调度。具体的，例如可以如图2所示，对于开启下行功率协调调度的小区，设定停止进行下行功率协调调度的PRB利用率阈值，小区对应的基站在第一预设周期内，每获取到每个小区的PRB利用率，根据每个小区的PRB利用率确定出PRB利用率最大值，将PRB利用率最大值与设定的停止进行下行功率协调调度的PRB利用率阈值进行比较，当PRB利用率最大值小于设定的停止进行下行功率协调调度的PRB利用率阈值的10％时，使簇内的每个小区停止进行下行功率协调调度，从而在小区的PRB利用率降低时，停止进行下行功率协调调度，减少基站的处理量。After the downlink power coordinated scheduling is enabled in the cell, if the downlink power coordinated scheduling is performed on the cell with the downlink power coordinated scheduling enabled, the processing capacity of the base station will be increased, and the efficiency of the base station will be reduced. Therefore, it is necessary to stop the downlink power coordinated scheduling of the cell. Coordinate scheduling. Specifically, for example, as shown in FIG. 2 , for a cell with downlink power coordinated scheduling enabled, the PRB utilization threshold for stopping downlink power coordinated scheduling is set, and the base station corresponding to the cell acquires every According to the PRB utilization rate of each cell, the maximum value of the PRB utilization rate is determined according to the PRB utilization rate of each cell, and the maximum value of the PRB utilization rate is compared with the set PRB utilization rate threshold for stopping downlink power coordinated scheduling. When the PRB utilization rate When the maximum rate is less than 10% of the set PRB utilization threshold for stopping downlink power coordinated scheduling, stop each cell in the cluster from performing downlink power coordinated scheduling, so that when the PRB utilization rate of a cell decreases, stop downlink Power coordination scheduling reduces the processing load of the base station.
可选的，功率协调方法还包括：根据调整后的终端设备的下行发射功率，调整终端设备的MCS配置信息。Optionally, the power coordination method further includes: adjusting the MCS configuration information of the terminal device according to the adjusted downlink transmission power of the terminal device.
本实施例中，每个UE的下行发射功率与MCS配置信息之间需要协调，当调整后的UE下行发射功率升高时，需要使MCS与调整后的UE下行发射功率，使调整后的MCS可以高效率的进行数据传输；当调整后的UE下行发射功率降低，需要使MCS与调整后的UE下行发射功率，确保数据传输的可靠性。In this embodiment, the downlink transmission power of each UE needs to be coordinated with the MCS configuration information. When the adjusted UE downlink transmission power increases, the MCS and the adjusted UE downlink transmission power need to be adjusted so that the adjusted MCS Data transmission can be performed efficiently; when the adjusted UE downlink transmit power is reduced, it is necessary to make the MCS and the adjusted UE downlink transmit power to ensure the reliability of data transmission.

The centralized scheduling node in the base station is based on the measurement report and the PRB utilization rate of each cell and the calculated Determine the target downlink transmit power of the UE based on the user rate of the terminal device. Moreover, the centralized control node is divided into: a centralized clustering node and a centralized scheduling node, wherein the centralized clustering node performs a cell clustering function and maps the clusters to a specific centralized scheduling node for processing.

可选的，对于一些应用场景，例如，基站覆盖下的小区包括医院、学校或者覆盖下的区域内有大型会展、重要会议时，所属区域内的QCI可以根据实际需求预先配置。因此，对于例如医院、学校或者覆盖下的区域内有大型会展、重要会议的区域，可根据实际需求预先设置UE差异化策略，建立特征库，实现智能化匹配，即当UE进入到预先设置UE差异化策略的区域时，该UE的下行发射功率根据与其进入的区域的UE差异化策略进行调整，使这些UE的用户能够获取更多的发射功率、更小的干扰和更多的调度资源，进而提升用户的感知。并且，减少基站处理量。Optionally, for some application scenarios, for example, when the cells covered by the base station include hospitals, schools, or there are large-scale exhibitions and important conferences in the covered area, the QCI in the area to which it belongs can be pre-configured according to actual needs. Therefore, for hospitals, schools, or areas with large-scale exhibitions and important conferences in covered areas, UE differentiation strategies can be preset according to actual needs, and a feature library can be established to achieve intelligent matching. That is, when the UE enters the pre-set UE In an area with a differentiated strategy, the downlink transmit power of the UE is adjusted according to the UE differentiated strategy of the area it enters, so that users of these UEs can obtain more transmit power, less interference and more scheduling resources. Thus improving user perception. Moreover, the processing load of the base station is reduced.
