1. A data scheduling method, comprising:
receiving channel quality information sent by a first terminal, wherein the first terminal is a terminal for which multiple carriers are activated;
calculating a current instantaneous scheduling rate of the first terminal on a first component carrier by using the channel quality information;
acquiring an average scheduling rate of the first terminal on the first component carrier;
calculating a scheduling priority of the first terminal on the first component carrier by using the current instantaneous scheduling rate and the average scheduling rate;
allocating a physical resource of the first component carrier to the first terminal according to a descending order of scheduling priorities of terminals to which the physical resource needs to be allocated, wherein the terminals to which the physical resource needs to be allocated comprise the first terminal and a second terminal;
determining that the first component carrier is a primary component carrier or a secondary component carrier of the first terminal; and
wherein allocating the physical resource of the first component carrier to the first terminal according to the descending order of scheduling priorities of terminals to which the physical resource needs to be allocated comprises:
when the first component carrier is the secondary component carrier of the first terminal, and when the first component carrier is a primary component carrier of the second terminal or the second terminal is a non-multi-carrier terminal, after allocating the physical resource of the first component carrier to the second terminal, allocating the physical resource of the first component carrier to the first terminal, and
when the first component carrier is the primary component carrier of the first terminal and the first component carrier is a secondary component carrier of the second terminal, after allocating the physical resource of the first component carrier to the first terminal, allocating the physical resource of the first component carrier to the second terminal.
