Title:
METHOD AND APPARATUS FOR SUPPORTING DIFFERENT CELL RANGE PER MODULATION IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/163672
Kind Code:
A1
Abstract:
A method and apparatus for transmitting data in a wireless communication system is provided. An evolved NodeB (eNB) configures a first power for a first modulation and a second power for a second modulation. A modulation order of the second modulation is higher than a modulation order of the first modulation. The eNB transmits data to at least one of a first user equipment (UE) with the configured first power or a second UE with the configured second power. The configured first power may be greater than the condifued second power. Accordingly, a proactive cell range expansion (P-CRE) may be implemented for the first modulation.
