METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING A CONTROL CHANNEL IN A MOBILE COMMUNICATION SYSTEM

摘要

A method and apparatus for transmitting a control channel of a base station in a mobile communication system. A downlink control channel signal generator generates a downlink control channel signal to be transmitted to a User Equipment (UE). A control channel candidate processor calculates a control channel decoding attempt order according to a state of the downlink channel. A controller determines a control channel candidate to be used, according to the calculated decoding attempt order. A mapper maps the generated control channel signal to the determined control channel candidate. A transmission processor wirelessly transmits the mapped signal.
