Abstract

The present invention provides a fast clustering scheduling method for simultaneous and same-frequency full-duplex users. within the cluster. Then adjust the clusters of users with low SNR according to the estimated interference situation, so as to ensure that the SINR reduction of all users in the area does not exceed a certain threshold after the change. If there is a new user access, it is divided into a certain cluster according to the interference situation, and the new cluster center is selected by using the K-means algorithm. The present invention is a simultaneous same-frequency full-duplex communication technology using self-interference elimination means. By adopting a user clustering strategy, the mutual interference between users in the clusters is minimized, and simultaneous same-frequency full-duplex communication is realized. Improve system communication efficiency.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a fast clustering scheduling method for simultaneous and same-frequency full-duplex users. Background technique [0002] Today, the available spectrum resources in various countries in the world are decreasing day by day, while the demand for wireless communication traffic is increasing rapidly. This external contradiction makes improving the utilization of spectrum efficiency an important research direction for improving the development of communication technology. [0003] Traditional communication systems are generally divided into simplex systems, half-duplex systems, and full-duplex systems. Full-duplex means that communication nodes receive and transmit at the same time. Simultaneous full-duplex technology at the same frequency refers to transmitting and receiving at the same time and frequency spectrum resources. It is a new duplex technology emerging in recent years...
