Scheduler modes

“

(gentle music) - [Instructor] Now we talked about the scheduler, where the MAC layer is responsible for distributing time and frequency resources to all the user in that particular cell. It constantly makes a real time decision. Now, let's take an example where we have three different users in a particular cell. It has a different signal strength, it has different quality, and therefore different MIMO capabilities. Now let's compare different scheduler modes in this case. Now the choice of scheduler has a significant impact of network performance, such as throughput delay and fairness index. Let's see that for these three users. So we are taking different scheduler modes. The first one is MAX C by I, where there's MAX carrier to interference ratio. This mode gives priority to the users with the best channel quality. So for example, here in this case, UE 1 is having a good quality. It gives a priority to this particular user to allocate more resources. Now, here we have certain pros…
