Patent ID: 8862142

Claim:
A coordinated scheduling method in Coordinated Multiple Point transmission, comprising: determining, by a central control cell determined in a region, priorities of users to be scheduled in all coordinated cells according to user information coming from the all other coordinated cells in the region; scheduling, by the central control cell, a user in each of the coordinated cells according to the determined priorities, and informing by the central control cell a corresponding coordinated cell of information on a user that is finally determined to be scheduled; and scheduling, by the corresponding coordinated cell, the user in corresponding time and frequency resources, after receiving the scheduling information from the central control cell; wherein the central control cell is determined in this way: a coordinated cell in the region is randomly selected as the central control cell at different coordination moments; or the coordinated cells in the region serve in turn as the central control cell at different coordination moments; or a coordinated cell with relatively little traffic in the region is selected as the central control cell at different coordination moments; or once the central control cell is determined, no new central control cell is selected in following coordination time; wherein the scheduling a user in each of the coordinated cells according to the determined priorities comprises: the central control cell selects a user with the highest priority and acquires, based on a preset weight criterion, a weight value matched with the user with the highest priority according to channel measurement information of the user with the highest priority; the central control cell determines a next optimal matched user to be scheduled and a corresponding weight value according to a preset optimal matching criterion; and the central control cell repeatedly determines a next optimal matched user to be scheduled and a corresponding weight value according to the preset optimal matching criterion until a preset scheduling ending condition is met, and then ends selecting a user to be scheduled.
