Abstract:
A method for switching between periodic transmission and aperiodic transmission of a channel estimation reference signal for scheduling resources in an Orthogonal Frequency Division Multiple Access (OFDMA) system and an apparatus to transmit/receive the reference signal using the same. To schedule periodic and aperiodic transmission of the channel estimation reference signal, a predetermined type of transmission indicator is used, the transmission indicator including one or more bits of a periodic/aperiodic identification indicator. According to the present embodiment, when periodic and aperiodic transmission of the channel estimation reference signal is mixedly performed, interference between user equipment or between cells can be minimized, and a transmission efficiency of the reference signal can be enhanced.
