METHOD BY WHICH MIMO TRANSMITTER FORMS RE GROUP

摘要

Disclosed are a communication method and a MIMO transmitter for measuring the inter-channel relationship of a plurality of resource elements (REs) on the basis of channel information of the plurality of REs, and dividing the plurality of REs in consideration of the measured inter-channel relationship, thereby forming one or more RE groups, and transmitting information on the RE groups to a MIMO receiver.
