MIMO REFERENCE SIGNAL GENERATION METHOD IN WIRELESS COMMUNICATION SYSTEM SUPPORTING MASSIVE MIMO

摘要

Generates a reference signal sequence to be applied when the number of antenna ports used for data transmission is 9 or more, maps a reference signal sequence to a resource area allocated to each of a plurality of antenna ports, and transmits a sub- The resource region to which the reference signal sequence for the ninth antenna port is mapped and the resource region to which the reference signal sequence for the tenth antenna port are mapped are the same, A reference signal generation method in which a reference signal sequence for a port and a reference signal sequence for a 10th antenna port are multiplexed by a CDM scheme is disclosed.
