Radio transmission apparatus and radio reception apparatus

Abstract

A radio transmission apparatus may include transmission section (105) that transmits a radio link signal, and control section (101). The radio link signal includes a phase variation correction reference signal used for correction of phase variation in a propagation channel in some cases. Control section (101) controls whether to map the phase variation correction reference signal to the radio link signal, or controls a mapping interval of the phase variation correction reference signal in the radio link signal, based on a time length or a type (Non-slot-based type or not) of a slot as a resource allocation unit.
