MOBILE COMMUNICATION SYSTEM AND MOBILE WIRELESS TERMINAL APPARATUS

摘要

A base station transmits a control channel C1 transmitted before information channels D3 - D7 upon performing differential coding between control channels C1 of adjacent frequencies. A terminal apparatus performs transmission path estimation on the basis of a pilot R2 while decoding the control channel C1 having undergone the differential coding. The information channels D3 - D7 are decoded on the basis of information obtained by decoding the control channel C1 and a transmission path estimation result on the pilot R2.
