It is the number of symbols within a slot. There is another varying parameter with numerology. Then what should get different to accomondate the physical property of the different numerology ? The anwer is to put different number of slots within one subfame. The length of a Radio Frame is always 10 ms and the length of a However, regardless of numerology the length of one radio frame and the length of one subfame is same. See Physial Layer Timing Unit page to see how these numbers are derived and to see some other timing units.Īs described above, in 5G/NR multiple numerologies(waveform configuration like subframe spacing) are supported and the radio frame structure gets a little bit different depending on the type of the numerology. Sampling time can be defined differently depending on Numerogy (i.e, Subcarrier Spacing) and in most case two types of Timing Unit Tc and Ts are used. Refer to Numerology page for further details.
NOTE : There are much more information you need to know about the numerology in addition to this table. If you are intrested in those long discussions and histories about show these specification came out for your personalinterests and study, refer to 5G Frame Structure Candidate page. In this page, I will describe on NR Frame Structure that is specified in 3GPP specification (38.211). There has been long long discussions on frame structure both in academia and in 3GPP and now we have pretty clear agreements on what a NR(5G) radio frame would look like.
