How many RBs do you need for CORESET?

Hi Experts.

Does anyone knows how do we assign that parameter where I indicated?
What does it mean 1 1 1 1 1… 0 0 0 0 0 … 0 0 0 0 0 0 0 0 … 0 0 0 0 0 …

Here each bit represents group of 6RBs.
In this example CCE agg level is 16 with one candidate n1.
And already RBs are calculated above 96RB. 1CCE =6RB. Means 16x6= 96.
These resources are allocated in frequency domain using bits.
With duration 1 symbol in time domain.

Above is the simple explanation.
You can find more details in 38.211.

Hi friends,

In general, the CORESETs are setup in 6PRBs units, in the sixth PRB grid and in the first, second or thrid OFDM symbol, in time domain.

In addition, a UE can be setup With 3 CORESETs in each one of the 4BWPs avaiable. Therefore, we can find until 12 CORESETs, for a UE.

I hope this helps.



It also depend on coreset & ssb multiplexing 1.
Normally pattern1 is used. Ssb frequency is 20 RB, so coreset at least 24 RB.
