what is the difference between DTX and DRX?

Question

If DRX is ongoing we cannot send SPS modification or release, so how do we configure DRX such that it will not affect SPS?

Answer 1

Hi Poonam,

DTX :

This state is to finalize the data is not received at either side(UE,eNB). Here data can be from any channels like PDSCH/PDCCH/PUCCH/PUSCH. if eNB/UE is not able to decode the data or CRC error means it is NACK. but if eNB/UE is not even able to receive or see the data means then it is DTX.

DRX :

In this case eNB/UE will be in OFF and ON combination for battery saving purpose.

DTX is data loss or no transmission. DRX is purposeful sleep combination.
