PUCCH Formats in 5G

This video provides an overview of various PUCCH formats in 5G. PUCCH is used to convey information from UE to Base Station, such as Acknowledgement, Scheduling request, and Channel State Report. Based on the payload size and channel conditions, various PUCCH formats are used.

Nicely explained

Thanks

[@user-fq9zt6pj7m]

I want new awesome video.

[@Orig_Xi_jinping_from_china]

Can anyone tell which 3gpp papers should I refer to understand mac layer ?

[@joeytsai5259]

The information about time/frequency of PUCCH should not included in DCI？ I can't find it on any type of DCI..

[@kranthiuppari4959]

Based on what type of data UE is sending pucch format is decided.
Eg : if SR has to send on pucch then Scheduling request resourceconfig from reconfig will give pucch - resource id which in turn maps to pucch resources in the reconfig.
For Ack/nack UE may get pucch resource I'd from the dci.

[@WirelessExplained]

There is a 3-bit parameter 'PUCCH Resource Indicator' inside DCI. This parameter points to one of the PUCCH-Config, which were already configured in UE's memory by RRC messages.
