A downlink (DL) precoding scheme that needs no DL training nor uplink (UL) feedback for massive MIMO systems operated under frequency-division duplex (FDD) is proposed. whereas most of the schemes in the literature were proposed to compress the overhead of training and feedback. Due to the above advantage. the proposed scheme is suitable for extremely low-latency applications. https://www.bekindtopets.com/quick-buy-Titans-Pets-First-Reversible-Dog-Bandana-deal-zone/
