Hi,

This is mentioned in MAC specification 5.7 .

If the Short DRX Cycle is used and [(SFN * 10) + subframe number] modulo (shortDRX-Cycle) = (drxStartOffset)
modulo (shortDRX-Cycle); or
- if the Long DRX Cycle is used and [(SFN * 10) + subframe number] modulo (longDRX-Cycle) = drxStartOffset:
- start onDurationTimer.

For E.g Current subframe number is 9. SFN is 988 , Longdrx cycle is 80 and drxstartoffet in RRC IE as 5

988 * 10 + 9 % 80 should be equal to 5.

What happen after paging

When a UE is in idle mode DRX, if it receive a paging message, it will establish RRC connection and become RRC-Connected
question:
1.Will its DRX mode become connected when it become RRC-Connected?
2.Will it turn to RRC-Idle when it received packet and there's no other packet coming?
3.If a UE is in connected mode DRX, will it still remain RRC-Connected when it's in sleep mode(opportunity for DRX)?

what happen after paging

When UE is in idle mode DRX and receive paging message, it will establish RRC connection, and when it become RRC-Connected, what happen next?
Does it change to connected mode DRX? or it will turn to RRC-Idle after receiving packet?

And I have another question
when a UE is in connected mode DRX, will it remain RRC-Connected when it turn to sleep mode(opportunity for DRX)?
