Claim:
1. A radio communication method comprising the steps in which a radio base station: sets at least three or more kinds of varying transmit power in a plurality of subframes constituting a radio frame, and also determines a power ratio between a reference signal and a shared data channel signal in each subframe; and generates bitmap information that represents a type pattern of transmit power set in the plurality of subframes; and reports the bitmap information and the power ratio to a user terminal and/or another radio base station, wherein the bitmap information is generated with reference to a table in which the power ratio of each subframe and identifiers are associated with each other, wherein the radio base station sets, as a configuration of the bitmap information, a base part that is formed with the same number of bits as the number of subframes reported using the bitmap information, and an extended part of a variable size.
