Does the UE knows, if there are RNTIs which can be skiped?

Question

I'd like to know, if there is a way for the UE to skip some RNTIs while descrambling the CRC of the PDCCH.

For example:
Is it possible to try the SIRNTI only in subframe #5, because this is the only slot where the SIB1 can be placed (if I'm not wrong)?
Or is it necessary to try every RNTI in every subframe?

Answer 1

Hi,

Ue will not decode all the RNIT in every SF, as you said SI-RNTI will be descrambled only in particular SF, P-RNTI will be only on IDLE or DRX mode configured SF. CRNTI and SPS-RNTI (if configured) will be checking in every SF..
