METHOD AND APPARATUS FOR DETERMINING CELL FOR EXECUTING COMP IN MULTI-CELL ENVIRONMENT

摘要

The present invention provides a method which determines an adjacent cell to carry out a coordinate multipoint transmission (CoMP) operation instead of performing the CoMP operation for all adjacent cells, in cases where precoding matrix indexes (PMI) of adjacent cells are limited to prevent interferences by adjacent cells in a multi-cell environment, thereby effectively reducing inter-cell interferences without causing an overhead.
