all include of defs.h by defs_nb_iot.h in 33 files.

adding NPDCCH structure for UE specific and Common Search space. To be implemented NPDCCH repetitions.Code Copile. 145 Warnings

introduction of some UE-specific parameters for NPDCCH (Seems missing in FAPI for the moment). Code copile, 149 warnings

Adding preliminary .config file for nb-iot (to be completed), adding EARFCN calculation for configuration with corresponding table for UE cat NB1/NB2

modified conditions for triggering the npdsch_procedure, still modulation, encoding...functions to be integrated. Warnings 144.Code compile

Setup of required variables for managing the SI messages transmission, according to our Assumptions. Still to include the function for encoding, scrambling ecc.. of npdsch and npdcch for the DL path. Code compile. 141 Warnings

integration of LCID for NB-IoT (MAC/defs_nb_iot.h), complete the thread for the phy_procedures_TX (Schedule_response) and other minor changes

review of PHY_Config_t structure parameters for FAPI-like approach. Implement the FAPI required parameters and adding some extras in separate structure. Code compile

Implementation of configuration data structures following FAPI-like approach. Some parameters seem to be non implemented in FAPI (for the moment addedd manually). Cleaning of some part of RRC code. Code compile.

Added new files for IF-module purposes (still to complete), review some configuration procedure for FAPI-like approach. Code compile

First implementation of FAPI-like P5 configuration for the PHY layer. PHY_Config_t structure, modified NB_rrc_mac_config_req_eNB for triggering the IF_Module PHY_config_req function. Some common config. and all the dedicated configuration are missed
