A METHOD OF TRANSMITTING DATA IN A MOBILE COMMUNICATION SYSTEM WITH MULTIPLE ANTENNAS

摘要

PURPOSE: A data communications method in a mobile communications system having a multiple antenna using a pilot allocation structure for effectively presuming channel is provided to supply a pilot allocation method having channel estimation performance. CONSTITUTION: A pilot symbol about a plurality of transmission antenna is allocated to a predetermined rate in a basic resources block. The data is transmitted by using the basic resources block in which the pilot symbol is allocated. The basic resources block is composed on the frequency axis on the subcarrier and time axis of 18 of an OFDM(Orthogonal Frequency Division Multiplexing) symbol. A time domain and a frequency domain are allocated in one domain.
