VARIABLE COORDINATION PATTERN APPROACH FOR IMPROVING PERFORMANCE IN MULT-CELL OR MULTI-ANTENNA ENVIRONMENTS

Japanese Patent JP2016029825

A

PROBLEM TO BE SOLVED: To provide a method and an apparatus for verifying a coordination pattern to improve performance in a multi-cell or a multi-antenna environment.SOLUTION: In a multi-cell or a multi-antenna, entities of a plurality of cells in a cluster composed of the plurality of cells is specified, and a coordination pattern, in which transmission should be performed in cooperation with each other on the transmission resource of different times and frequencies, is predefined and stored (301). According to the predefined coordination pattern, the entities of cells are varied, which are cooperated with each other in the cluster during transmission corresponding to the transmission resource of the time or frequency (302).SELECTED DRAWING: Figure 3
