Good explanation, sir. I have a few questions, so please clarify them. 1. If 15 kHz subcarrier = slot per subframe is 1 slot = 1 ms = 14 OFDM symbol, then 30 kHz subcarrier = slot per subframe is 2 slots = 1 ms = 28 OFDM symbol, and for 60 kHz subcarrier = slot per subframe, it is 4 slots = 1 ms = 56 OFDM symbol. Now, my question is this: A . What is the size of 1 slot, which means each slot's bandwidth size, for 15 kHz, 30 kHz, and 60 kHz? B. How much bandwidth contains 1 OFDM symbol? 2. Resource element (RE) consists 1 OFMD symbol in time domain and 1 subcarrier in frequency domain.1 slot =14 OFDM, where slot duration depends on subcarrier spacing. Now, my question is this: A. Is there any relation between slot and RE? B. 1RE = 1 OFDM symbol (also 1 subcarrier), and 1 slot = 14 OFDM symbols. so can I say , in 1 slot contain 14 RE or 14 subcarrier.
Hi I am sorry, I have not been working in 5G for some time now and it will be hard for me to answer your questions effectively now. I would refer to www.sharetechnote.com/html/5G/Handbook_5G_Index.html
What is the size of 1 slot, which means each slot's bandwidth size, for 15 kHz, 30 kHz, and 60 kHz? Answer: if we want to tell BW size its combination of sub carriers and symbols i.e PRB. BW won't express in terms of slots. B. How much bandwidth contains 1 OFDM symbol? Answer: same as above
Good explanation. But one disagreement - a resource element is not one symbol. A resource element is just one sub-carrier (out of several thousands) in the symbol.
Yep you are correct, I misspoke here. I was using OFDM symbols incorrectly, where and RE is a single subcarrier in an OFDM symbol as you point out. The subcarrier is occurring in the frequency domain and the OFDM symbol is occurring in the time domain
Thank you. Can you tell bit more about sampling time ? Does the UE then filter (split) the incoming signal into 12 different sub carriers using 12 band pass filters ? Also why the RB concept can not be held in time domain alone ? If there is composite signal from 12 sub carriers , we can use adjacent time windows of wider wider duration? Thanks again.
