Explore, in detail, the unified approach of 5G in terms of the air interface.
- [Instructor] Let's talk about the interface, … and similar to the spectrum observations, … we need something which is unified. … And really we are trying to bring together … a very different methodologies in here, … so we have the different OFDM configurations. … We have different frame structures. … We need to support advanced technologies, … such as massive MIMO millimeter wave. … We need to support different duplexing methodologies. … Well for that, ideally, we would like to have … a single interface, a single set of parameters … you could tweak to come up with that 5G setting … and accommodate the different technologies. … And that's how we do it, so you look … at the flexible radio frame design. … Don't even know where to start here. … But what you see is a time frequency grid. … So we have the time going from left to right, … and we have the frequency from bottom up into the slot. … So let's start with the frequencies as subcarriers. … You will have different subcarriers there …
