“…Then, all receiving nodes feed back a channel quality indicator (e.g., the measured SINR), and only the node exhibiting the best channel is scheduled. Despite the simplicity of this technique, [SYGM21] corroborates that opportunistic beamforming outperforms space-time coding in terms of sum rate when the channel response exhibits a slow variation. The major drawback of opportunistic beamforming is that the attainable performance degrades when the number of potential receiving nodes is low.…”

“…The major drawback of opportunistic beamforming is that the attainable performance degrades when the number of potential receiving nodes is low. However, this drawback can be counteracted by exploiting multiple antennas at each receiving node [SYGM21]. More recently, opportunistic beamforming has been studied in the novel framework of intelligent reflecting surfaces [NCD21].…”
