We consider an antenna selection scheme in single-user massive MIMO systems. We formulate a rate maximization problem with a sparsity promoting regularization function. The proposed algorithm allocates sparse power allocation among transmit antennas. It achieves a very high sum rate close to the optimal full search algorithm.
