Massive MIMO Unlicensed for High-Performance Indoor Networks
Massive MIMO Unlicensed for High-Performance Indoor Networks
We propose massive MIMO unlicensed (mMIMO-U) as a high-capacity solution for future indoor wireless networks operating in the unlicensed spectrum. Building upon massive MIMO (mMIMO), mMIMO-U incorporates additional key features, such as the capability of placing accurate radiation nulls towards coexisting nodes during the channel access and data transmission phases. …
