\brief This function performs a subset of the bit-coding functions for LTE as described in 36-212, Release 8.Support is limited to turbo-coded channels (DLSCH/ULSCH). The implemented functions are:
- CRC computation and addition
- Code block segmentation and sub-block CRC addition
- Channel coding (Turbo coding)
- Rate matching (sub-block interleaving, bit collection, selection and transmission
- Code block concatenation
@param eNB Pointer to eNB PHY context
@param input_buffer Pointer to input buffer for sub-frame
@param frame_parms Pointer to frame descriptor structure
@param num_pdcch_symbols Number of PDCCH symbols in this subframe
@param dlsch Pointer to dlsch to be encoded
@param frame Frame number
@param subframe Subframe number
@param rm_stats Time statistics for rate-matching
@param te_stats Time statistics for turbo-encoding
@param i_stats Time statistics for interleaving
@returns status
