RADIO COMMUNICATION METHOD, RADIO BASE STATION, USER TERMINAL AND RADIO COMMUNICATION SYSTEM

摘要

The present invention is designed to report transmit power information of each subframe adequately when a plurality of transmit power are set in a plurality of subframes constituting radio frames. A radio base station performs the steps of setting at least three or more kinds of varying transmit power in a plurality of subframes constituting a radio frame, and also determining a power ratio between a reference signal and a shared data channel signal in each subframe, generating bitmap information that represents a type pattern of transmit power set in the plurality of subframes, reporting the bitmap information and the power ratio to a user terminal and/or another radio base station, and generating the bitmap information with reference to a table in which the power ratio of each subframe and identifiers are associated with each other

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.
