hi,
if MS wants to send data in UL, the MFS allocates 1 UL TBF.
if network wants to send data to the MS (in DL), then the MFS allocates 1 DL TBF.
One MS can have 1 UL TBF, or 1 DL TBF, or 1 UL + 1 DL TBF.
In each “xL” TBF, a certain number of “xL” PDCH (timeslots) are allocated. (replace “xL” by UL or DL)
