METHOD FOR RECEIVING CONTROL INFORMATION IN ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING SYSTEM OF MOBILE COMMUNICATION SYSTEM

摘要

The present invention relates to receiving downlink signals at a mobile terminal in an orthogonal frequency division multiplexing (OFDM) system. The present invention includes receiving information related with a number m of OFDM symbol(s), wherein m OFDM symbol(s) from a beginning of a subframe is used for reception of one or more channels that carry acknowledgement/negative acknowledgement (ACK/NACK) information; and receiving information related with a number n of OFDM symbol(s), wherein n OFDM symbol(s) from the beginning of the subframe is used for reception of one or more channels that carry scheduling information, wherein the number n is equal to or greater than the number m and a transmission interval of the information related with the number m is greater than a transmission interval of the information related with the number n.
