Claim:
1. A method for transmitting data signals by using a massive Multi Input Multi Output (MIMO) in a wireless access system, the method performed by a transmitter and comprising: inputting bits of the data signals to a channel encoder; outputting from the channel encoder a first coded bit set including one or more coded bits and second coded bit set including one or more coded bits; and when a moving direction of a receiver is vertical to the transmitter, transmitting the first coded bit set through a horizontal antenna elements array according to a closed loop MIMO mode and transmitting the second coded bit set through vertical antenna elements array according to an open loop MIMO mode, or when a moving direction of the receiver is horizontal to the transmitter, transmitting the first coded bit set through the vertical antenna elements array according to the closed loop MIMO mode and transmitting the second coded bit set through the horizontal antenna elements array according to the open loop MIMO mode.
