METHOD OF TRANSMITTING FEEDBACK MESSAGE IN WIRLESS COMMUNICATION SYSTEM

摘要

PURPOSE: A method of transmitting a feedback message in a wireless communication system is provided to transmit narrow band information through a PFBCH(Primary Fast Feedback Channel). CONSTITUTION: An MS(Mobile Station) receives information about a first period and a second period from a BS(Base Station)(S400). The MS transmits a first feedback message every first period or transmits a second feedback message every second period to the BS on a PFBCH(Primary Fast Feedback Channel)(S410). The first feedback message comprises a CQI(Channel Quality Indicator) about a sub band selected among a plurality of sub bands. The second feedback message comprises a sub band index of the selected sub band.
