Today, we talk about the 5G NR MIMO Transmission ways. What are the required transmission schemes for NR MIMO?
There are three implementation options for the 5G NR beam assignment, which are analog, digital, and hybrid beam assignment. For these implementations, both multibeam-based and single-beam-based approaches should be considered. But what are the required transmission schemes for the 5G NR MIMO?
In LTE, single layer/multi-layer/TP/UE transmissions use a unified framework. Due to the flexibility of DMRS, these transmissions have good transparency. In 5G NR, multi-beam transmissions can also be seen as cooperative transmissions between multiple virtual TPs.
Considering the cost and complexity, when there are more antenna units and the number of RXUs is usually smaller than the number of originals.
