________ is used on the downlink channel to enable the base station to transmit different data streams to multiple users over the same frequency band.
A)OFDM
B)SC-FDMA
C)MIMO-BC
D)all of the above

Question

Quizplus · Accepted Answer

MIMO-BC (Multiple-Input, Multiple-Output-Broadcast) is the technology that is used on the downlink channel to enable base stations to transmit different data streams to multiple users over the same frequency band. OFDM (Orthogonal Frequency Division Multiplexing) and SC-FDMA (Single Carrier Frequency Division Multiple Access) are also used in wireless communication, but they are not solely responsible for enabling transmission to multiple users on the same frequency band like MIMO-BC. Therefore, option D is incorrect.
