Hey Experts.

Does we need to check CRC for PDCCH channel also in Downlink?

PDCCH is always sent with QPSK it is just that aggregation level is different and power is different too.

So there could be lot of coding in bad RF due to aggregation level 8 and less coding in good RF like aggregation level 2.

Yes DCI with CRC scrambled by rnti

I think no need to check.

As PDSCH, UE will feedback CRC result ACK/NACK.

But PDCCH, no feedback, so no check.

It is a must check. RNTI is embeded in CRC
