ABSTRACT:
A data transmission method for a MIMO (Multiple-input Multiple-Output) system allowing multiple terminals to share channelization codes according to the channel states, by receiving channel information from terminals, allocating channelization codes for each transmit antenna based upon the received channel information, and transmitting data via each transmit antenna according to the allocated channelization codes. When there are many user terminals and if the number of channelization codes are limited, namely, when the total number of channel codes used to distinguish the terminals is less than the total number of terminals, channelization code sharing per transmit antenna among multiple terminals is performed, such that the throughput of data that can be sent by using each channelization code is increased.
