AMBA Low power interface relation with QACTIVE, QDENY and PWAKEUP

It is about AMBA Low Power Interface Q-Channel.

I am using device which QDENY and QACTIVE are assigned with PWAKEUP.(assign QDENY = PWAKEUP/ assign QACTIVE = PWAKEUP)

'What I want to know is when QACTIVE is asserted, is it right that there is no condition to assert QDENY?'

If my question is right, when does device assert QDENY?

If my question is wrong, am I thinking right that QACTIVE and QDENY are independent signal?

I want to know exact relationship between QDENY and QACTIVE.
