Publication number: 20140099984Abstract: The present invention discloses a method for scheduling users in coordinated scheduling, which is applied in a long term evaluation-advanced system, a coordinated cell determines and stores user pairing information in initial scheduling, and the coordinated cell uses the user pairing information that has been stored to determine a scheduled user in subsequent iterative scheduling. The present invention also discloses a corresponding base station. With the scheduling schemes in the present invention, in intra-cell scheduling, user pairing information is stored in an initial scheduling process and is used in subsequent iterative scheduling without performing multiple user pairing search in the iterative scheduling, which reduces the computation amount in the iterative scheduling and system resources occupied by the iterative scheduling and accelerates the system processing time in a premise of not reducing the system performance, thereby making the performance in the whole domain trend to the optimal.Type: ApplicationFiled: December 9, 2010Publication date: April 10, 2014Applicant: ZTE CORPORATIONInventors: Kaibo TIAN, Feng LI, Changqing ZHU, Aihua PENG
