How can we predict the data rate from the subscriber side ?

As for uplink resources we know we need to know before that how much data UE has to send and how much is in buffer. That is ok but how can we predict the data rate for that data?

Scheduling Request message comes from UE at eNodeB and ask for radio resource in the granularity of 1ms. Whereas in lte QoS is based on Mbps (megabits per second).
As per my knowledge it is game of TFT DL as well as UL. Downlink TFT takes care of DL bit rate and UL TFT as UE takes care of uplink bit rate.

Please correct me if I am wrong.

Why the minimal MCS chosen by the eNodeB for the user?

As far as I know eNodeB calculates the number of Physical Resource Blocks allocated to each UE, based on the specific metric, then takes the minimal modulation and coding scheme to deduce the transport block size that must be allocated to each user, Why this minimal MCS ? Isn't it too sub-optimal?
