Abstract: Described herein is an omnidirectional space-time coding scheme allowing signals to transmit from a base station to multiple user equipments in a massive MIMO system with reduced pilot overhead and system complexity. The transmission scheme uses a low-dimensional space-time coding scheme to generate a K×T d code block, and based on the K×T d code block, using an M×K precoding matrix W to generate an M×T d code block for transmission over a large number of transmitting antennas, wherein K is much smaller than M.
