Good explanation of NR UL channels, indeed. However, I have a few things to comment: 1. When talking about RACH configuration maybe you should emphasize also msg1-FrequencyStart, as the position of RACH channel in frequency domain is very important, especially when UL has configured continuous PRB allocation. 2. For Long PUCCH Formats you said that in one slot there will be one freq. position of PUCCH channel (PRB 272), while in another slot frequency there will be secondHopPRB position (PRB 0). However, I can see from the configuration that intraSlotFrequencyHopping is enabled and, as per my understanding, that means that in first 7 symbols within one slot PUCCH channel will be at position 272, while in the next 7 symbols within the same slot PUCCH channel will be at position 0.

Nice, so SRS is valid only for TDD? For 700 FDD bands does SRS exist ?
@OurTechPlanet
9 ай бұрын
SRS can exist for FDD as well. But mostly used in TDD because TDD has same frequency channel in DL and UL so the Node can use SRS to estimate the channel weights for DL.

Any reason of using 2 PDCCH/PDSCH Blocks in example for long PUCCH or is it by 3gpp standard?
@OurTechPlanet

No specific reason, just to clarify the difference in feedback delay between Long and Short PUCCH. It depends on the TDD format used. It can be 3 PDCCH/PDSCH Blocks (Slots) if we are using 3:1 DL/UL format or it can be 4 Slots if we are using 4:1 DL/UL format.

yes the functionality of dmrs is similar i.e. used for demodulation of the data. It cannot be changed dynamically (e.g. the number of symbols used for DMRS are 2 then 2 symbols will be used throughout the connection).
