APPARATUS AND METHOD FOR CHANNEL-STATE-INFORMATION REFERENCE SIGNALS

摘要

The present invention relates to a 5th generation or pre-5G communication system for supporting a transmission rate higher than a 4th generation communication system such as long term evolution (LTE). The method of operating a base station according to aspects related to a wireless environment includes: a process of generating a reference signal sequence for sub-carriers and OFDM symbols; and a process of generating a complex-valued modulation symbol to correspond to code division multiple-4 by mapping the reference signal sequence according to an assigned formula.
