The mathematical expression of this complementarity is captured by the Heisenberg uncertainty principle, which states that a signal cannot be simultaneously localized to any desired degree in time and in frequency.
[10] This immunity amounts to slowing down the channel aging process, which has implications for various network functions that require extended latency, such as MU-MIMO[4][9] and CRAN.
When the delay-Doppler channel representation is appropriately incorporated in MU-MIMO architecture, it enables non-trivial network functionality, such as intelligent user pairings and SNR predictions.
[13] Due to its geometric nature, the slow changing Delay Doppler channel representation opens up the door for functionality disaggregation.
The software can reside in the near-real time RAN Intelligent Controller (RIC) as an xAPP within the O-RAN architecture and can support hyper-reliable, low latency 5G requirements.
