Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0036] In order to reduce the complexity brought by the exhaustive search traversal, an embodiment of the present invention proposes a coordinated multipoint (CoMP) scheduling method, so as to reduce the complexity of CoMP scheduling. Furthermore, the method proposed in the embodiment of the present invention can be close to the optimal CoMP performance of the exhaustive search method to a large extent. Specifically, the flow of the coordinated multi-point scheduling method proposed by the embodiment of the present invention is as follows figure 1 shown.

[0037] In step 101, a CoMP cooperating set is determined. In a specific implementation, the CoMP cooperating set includes at least two transmission points (TP, transmission point), and the transmiss...

Abstract

The invention provides a coordinated multiple point (CoMP) scheduling method and a corresponding base station. Specifically, the CoMP scheduling method comprises the following steps of: determining one or more CoMP user combinations in a CoMP coordination set; determining one or more transmission states for each CoMP user combination, and figuring up scheduling priority of each transmission state; and selecting highest priority from the scheduling priority corresponding to one or more transmission states of one or more CoMP user combinations, and carrying out user scheduling according to the transmission state corresponding to the highest priority. According to the method provided by the invention, scheduling complexity of a communication system can be reduced well.

Description

technical field [0001] The present invention relates to the communication field, in particular to a coordinated multi-point (CoMP, coordinated multi-point) scheduling method and a base station for realizing the method. Background technique [0002] Coordinated multi-point (CoMP, coordinated multi-point) technology reduces inter-cell interference and improves system performance through joint scheduling and coordinated transmission of multiple cells (cells). In theory, CoMP scheduling requires flexible and dynamic switching among multiple CoMP schemes, so as to ensure the optimal performance of CoMP. Specifically, the CoMP scheme may include: coordinated scheduling / dynamic point blanking (CS / DPB, coordinated scheduling / dynamic point blanking), dynamic point selection / dynamic point blanking (DPS / DPB, dynamic point selection / dynamic point blanking), DPS only , and joint transmission (JT, joint transmission), etc. Each CoMP scheme has multiple possible transmission states, and ...
