Efficient reduction of inter-cell interference using RF agile beam forming techniques
摘要:
In embodiments of the present disclosure improved capabilities are described for reducing inter-cell interference in a large area broadband LTE wireless network utilizing RF agile beam forming antennas, where the reduced inter-cell interference is realized by arranging the sets of rotating RF beams in each cell such that adjacent RF beam sub-areas in the same or in different cells are not illuminated at the same time. The reduction in inter-cell interference results in reduced interference noise for users located near the edges of cells, thereby allowing them to be assigned higher data rates. Also, the same set of sub-carriers can be assigned by adjacent cells to users located in the RF beam sub-areas at the cell boundaries, thereby allowing the complete set of LTE sub-carriers to be assigned to any user at any time, without requiring additional cell-to-cell communications.
