changes in BSR handling in eNodeB. UL throughput on 5 MHz is 8 Mbit/s (mcs 19, 20 PRB). MCS 20 is not working for an unknown reason.

increase maximum users in eNodeB to 16

some changes in logging for XFORMS and UL scheduling (activation in all subframes and retransmissions only via PHICH)

handling of timing advance is improved. MAC retrieves timing advance from phy once prior to DL scheduling and clears the statistic in PHY. A timer for controlling the timing advance periodicity was introduced.

Limitation of non SI DLSCH allocations in subframe 0/5 to PRBS not around DC (avoid puncturing from PBCH). Placement of SI around DC instead of randomized allocations. Placement of RA allocations at PRB 0-3.  Tested DL throughput on 5 MHz to 16 Mbit/s in TM1.

Added DLSCH scheduling for subframes 0 and 5. Changes in MAC scheduling data structure to keep track of VRB allocations from SI,RA when scheduling regular DLSCH

CCE Allocation in MAC, rebase from develop. Frame number limitation to 1024 for non-real time targets (caused bad bug in oaisim).

The observed behavior (samsung phone, lte dongle, sequans box) is that the UE
keeps connecting over and over again.
