Optimizing RACH: Dynamic preamble allocation

“

(gentle music) - [Speaker] Let's understand the dynamic preamble allocation feature in a little bit more detail. And we'll start with one analogy where imagine a concert venue for just two ticket booth for 10,000 fans. That's what fixed preamble allocation feels like for 5G devices. We'll discover that how base stations automatically scale preamble resources, and handle massive device crowds using these features. There are different steps involved. The very first step is preamble scaling revolution. It's more about adaptive resource management where static system fails when device counts increases simultaneously. So we have a dynamic solution for that. gNB continuously monitors UE density instantly allocates more preambles when needed, and it prevents excess gridlock during peak hours. We also have control for the devices during high-density. We have up to four times more preamble allocated during the high-density…
