RADIO BASE STATION APPARATUS, MOBILE TERMINAL APPARATUS AND WIRELESS COMMUNICATION METHOD.

摘要

Provided are a radio base station apparatus, a mobile terminal apparatus and a wireless communication method wherein a downlink channel quality determination reference signal is transmitted and received in consideration of highly precise interference estimation. According to the wireless communication method, the radio base station apparatus generates and maps a channel quality determination reference signal to two adjacent symbols, and the mobile terminal apparatus receives a downlink signal including the channel quality determination reference signal mapped to the two adjacent symbols and performs an interference power estimation by use of the channel quality determination reference signal mapped to the two adjacent symbols.
