Hello,
I am trying to create a small script to generate 5G signals to transmit through an SDR device. My problem is related to the reservation of resources for sync signals. I generate the SSB grid and, then, I want to reserve the resource blocks corresponding to those symbols when generating the PDSCH indices and symbols. For that purpose, I create a nrPDSCHReservedConfig object with the subcarriers and symbol positions where the SSB is expected to be allocated, but this information is not considered when generating the indices of the other signals (nrPDSCHIndices). Could you provide me some feedback about the best way to do that?
Thank you very much.
Christian

Hi Christian
Can you please provide the script your tried with nrPDSCHIndices? So that it helps to know where the issue was. You can use the paperclip icon to attach the script.

Hi Christian,
Thanks for sharing the code.
The issue of PDSCH not rate-matching around the SSB comes from the incorrect assignment of subcarriers, instead of resource blocks for the property PRBSet of reservedPRB1.
Make the following update and it would work as expected:
reservedPRB1.PRBSet = floor((ssb_freqs)/12-1); % convert subcarriers to resource blocks
As the property name PRBSet, it indicates that resource blocks need to be provided and any value provided is taken as a separate resource block.
Hope this helps.
Thanking you.
Regards,
Sriram
