I came across the below book
' HSDPA/HSUPA for UMTS : High Speed Radio Access for
Mobile Communications' and this has the calculations for
RTT , Packet Call setup, the kind of assumptions made ,
the configurations made at various levels .
Is there any similar document/standard/book so that
we can arrive at the method of the calculation
of the delays mentioned in the LTE Technical report -
3GPP TR 25.912 V8.0.0 (2008-12) ?
Thx in advans,
