BASE STATION APPARATUS, TERMINAL APPARATUS, COMMUNICATION SYSTEM AND COMMUNICATION METHOD

摘要

This invention mainly relates to a precoding process and achieves an efficient adaptive control in a communication system that transmits a data signal demodulation reference signal together with data signals. A resource block bundling unit, which consists of at least one resource block, is determined as a resource block bundling rule, and a common precoding process is performed, for the data signals, in the resource block bundling unit.
