put 50 PRB back in default enb configuration. added handling of UE release in L1/L2. detection of stale ULSCH configuration

removal of LOG_I put for debugging.

fixes for precoding (turning off if nb_antennas_tx=1), configuration files, timing advance with 3/4 sampling on 20 MHz, logging in MAC

Result of testing as eNodeB. modifications for .vcd logging, bugfix in eNB_thread_FH (subframe counter), update of .conf file for new threading parameters. Updates to gtkwave configuration file for new threading.

added Timing advance tracing to .vcd output. Increase maximum UL RB count to 45. Measured UL throughput @ 15 Mbit/s (40 PRBs).

added configuration file for lowband of SoDeRa

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.
