Later, antenna reception scheme becomes 4TX/1RX or 2TX/1RX or 1TX/1RX by 4TX/2RX or 2TX/2RX1 or 1TX/2RX,
Diversity gain is only received without SNR has the decline of 3dB or so according to multi-path environment, but controls the receptivity of signal
Redundancy is larger, is influenced less so SNR declines to receive control channel；
For PDSCH MIMO transmissions, become leading to the two of PDSCH channels after 1 antenna receives from receiving the reception of 2 antennas
A TB data blocks are interfered each other, a large amount of error codes occur；For the transmission mode of other PDSCH channels, reception antenna is by 2
Without diversity gain is received after becoming 1, SNR has the decline of 3dB or so according to multi-path environment, since LTE base station is still protected
