Coordinated node point selection and wireless resource dispatching method in coordinated multi-point transmission technology

Abstract

The invention discloses a coordinated node point selection and wireless resource dispatching method in coordinated multi-point transmission technology. In the method, firstly, coordinated user sets and non-coordinated user sets are confirmed preliminarily; then the preliminary compartmentalization of coordinated sets is carried out; and finally, the coordinated set of each user is further confirmed for conducting wireless resource dispatching. Through the stepwise optimization of the coordinated sets, the re-dispatching can be conducted for the coordinated users who are not distributed with resource during the resource dispatching, and the optimization of resource dispatching is conducted in the coordinated sets, so that under the condition of smaller complexity, the same frequency interference in a small region is reduced, the throughput of users at the edge of the small region is improved, and the fairness for the users is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, in particular to a cooperative node selection and wireless resource scheduling method in a coordinated multi-point transmission technology (CoMP, Coordinated multi-point transmission). The method can improve the throughput of the cell edge users and improve the performance of the system. Background technique [0002] With the development of wireless communication technology, people's requirements for the performance of wireless communication systems are also increasing. In LTE (Long Term Evolution), users at the center of a cell are less interfered by adjacent cells, while users at the edge of a cell are more interfered, and this interference is relatively difficult to deal with. The CoMP technology can eliminate the interference of adjacent cells to cell edge users and improve the throughput of cell edge users. Therefore, in LTE-A, the cooperative node transmission technology is ...
