Abstract
The present disclosure provides a method for controlling a power, comprising: determining an average basic transmission power of all User Equipments (UEs) in a cell in each first resource; for each first resource, determining a UE group scheduled in the first resource and a first transmission power allocation factor corresponding to the UE group according to the average basic transmission power. The present disclosure also provides an apparatus for controlling a power. According to the present disclosure, a base station determines a UE group scheduled in each subband and a transmission power for each UE in the UE group.

A method for controlling uplink transmission power, comprising:
- for each resource of a plurality of resources, determining an average basic transmission power of all User Equipments (UEs) in a cell;
- for a first resource in the plurality of resources, determining a UE group scheduled in the first resource and a first transmission power allocation factor corresponding to the UE group according to the average basic transmission power;
- wherein determining the UE group scheduled in the first resource and the first transmission power allocation factor corresponding to the UE group comprises:
- listing up all possible UE combinations as a set of candidate UE groups;
- for each candidate UE group in the set of candidate UE groups, calculating a total transmission power according to the average basic transmission power a number of UEs in the candidate UE group and a compensation factor;
- for each candidate UE group in the set of candidate UE groups, listing up all possible transmission power allocation factors as a set of candidate transmission power allocation factors corresponding to each candidate UE group;
- arranging and combining the candidate UE groups and the candidate transmission power allocation factors, and obtaining all combinations of a candidate UE group and a candidate transmission power allocation factor;
- for each combination of a candidate UE group and a candidate transmission power allocation factor, determining a transmission power allocated to each UE in the candidate UE group according to the total transmission power of the candidate UE group and the candidate transmission power allocation factor, and calculating a scheduling metric of the candidate UE group according to the allocated power;
- determining a candidate UE group and a corresponding candidate transmission power allocation factor which achieve a maximum scheduling metric in the first resource as the UE group scheduled in the first resource and its corresponding first transmission power allocation factor, respectively.
