Francisco 1f35c4dc8b sched, feature enhancement, bugfix - allow RAR DL grants with variable PRB size 
Some bug fixes had to be solved:
- the cfi cannot be dynamic once we set a SIB/paging/RAR allocation. This is too avoid effective coderate to exceed its maximum
- the previous bugfix required adding the feature to cancel the last PDCCH+PDSCH allocation

Andre Puschmann 20cbc48f90 rlc_am_lte: refactor PDCP/RLC interface to use fix sized data structure 
this patch replaces the std::vector type used in the interface between
PDCP and RLC to signal delivery status between both layers. The new
data type is a configurable but fixed-size vector.
The RLC AM doesn't need to dynamically allocate the vector for every SN but
uses the tx_window for storage.

Francisco 34e39a9835 Implementation of scheduler algorithm to avoid PUCCH collisions
