The PBR is the data rate provided to one logical channel before allocating any transmission resource to a lower-priority logical channel)

The idea behind prioritized bit rate is to support for each bearer, including low priority non-GBR bearers, a minimum bit rate in order to avoid a potential starvation. Each bearer should at least get enough resources in order to achieve the prioritized bit rate (PRB).

LTE: How does eNodeB enforce uplink data rate and what eNodeB does in case when UE is not following the uplink limit ?

This is not a usual case. Assume an eNodeB has multiple bearers (GBR and non-GBR) with the UE, eNodeB enforces subscribed downlink data rate by using the different scheduling algorithm. Can eNodeB reject the uplink grant assuming UE is crossing its subscribed limit ?

Recommended Bit rate in LTE MAC header

What is the use of "Recommended Bit rate" in LTE MAC header ?

My another Q is can MAC restrict data rate per Bearer /or logical channel if they are mapped to same Physical channel..I guess yes :)
But i have not been working on LTE Radio, so obviously need some expert opinion before discuss with legacy radio experts ?

LTE: When RLC 15-bit LI value is used in AM mode ??? Based on what condition.

As per 3gpp 36.322 Release 12.0 RLC specification, Extended RLC LI field = 15 bit is newly included in AM mode.
Can anyone please explain, exactly in what condition this 15-bit LI value will be used.
