1.The MS shall send the Countdown Value (CV) in each uplink RLC data block to indicate the current number
of remaining RLC data blocks for the uplink TBF.
Lets assume
x=round((TBC-BSN-1)/(NTS x S))
then CV=x ,if x=< BS_CV_Max
or CV=15,if x> BS_CV_Max
TBC=total number of RLC data blocks currently to be transmitted in the TBF.
BSN=Block sequence no. of the RLC
NTS=number of timeslots assigned to the uplink TBF
S=2,usually.
2.I think you can check the CV value in the UL mode reports.
