void ue_mac_scheduler_tx (unsigned char Mod_id)
void ue_mac_scheduler_rx (unsigned char Mod_id)
void nodeb_generate_chbch (unsigned char)
 This routine first retrieves the BCCH and CCCH logical channels from RRC. It then fills the UL and DL allocation maps as well as feedback channels in a CHBCH_PDU structure. Finally it generates a MACPHY_DATA_REQ for the PHY CHBCH transmitter.
void ch_fill_dil_map (unsigned char Mod_id, LCHAN_INFO_DIL_TABLE_ENTRY *Lchan_entry)
 This routine fills the CHBCH_PDU entries corresponding to a particular direct link logical channel.
void ch_fill_dl_map (unsigned char Mod_id, LCHAN_INFO_TABLE_ENTRY *Lchan_entry)
 This routine fills the CHBCH_PDU entries corresponding to a particular downlink logical channel.
void ch_fill_ul_map (unsigned char Mod_id, LCHAN_INFO_TABLE_ENTRY *Lchan_entry)
 This routine fills the CHBCH_PDU entries corresponding to a particular uplink logical channel. It operates in TTI $N-1$ and prepares a CHBCH_PDU which will be on-air in TTI $N$. Furthermore, the UL_MAP is used to schedule the RX resources (UL-SACH) for TTI $N+1$.
void nodeb_scheduler (unsigned char Mod_id)
 This routine is the top-level entry point for NodeB physical resource scheduling. It performs downlink, uplink and direct link scheduling for the next TTI based on measurement feedback (RF and traffic) from nodes and local measurements.
void nodeb_get_sach (unsigned char Mod_id)
 This routine generates a MACPHY_DATA_REQs in order to program NodeB PHY to receive a SACH and corresponding SCH. This is invoked in TTI $N-1$ for action in TTI $N$. The result is seen by NodeB MAC in TTI $N+1$.
void nodeb_decode_sch (unsigned char Mod_id, UL_MEAS *UL_meas, unsigned short Index)
 This routine extracts the PHY measurements received from an SCH channel.
void nodeb_process_sacch (unsigned char Mod_id, LCHAN_INFO_TABLE_ENTRY *Lchan_entry, unsigned char Lchan_index, unsigned char User_index, UL_SACCH_PDU *Sacch_pdu)

 This routine extracts the UL_SACCH information. It does nothing for the moment.
void nodeb_get_rach (unsigned char Mod_id, unsigned char nb_rach)
 This routine generates a MACPHY_DATA_REQ in order to program NodeB PHY to receive a set of RACH. This is invoked in TTI $N-1$ for action in TTI $N$. The result is seen by NodeB MAC in TTI $N+1$.
void nodeb_decode_rach (unsigned char Mod_id, RACH_PDU *Rach_pdu)
 This routine extracts the UL_SACCH information. It does nothing for the moment.
void nodeb_generate_sach (unsigned char Mod_id)
 This routine first retrieves the maps as well as feedback channels in a CHBCH_PDU structure. Finally it generates a MACPHY_DATA_REQ for the PHY DL_SACH transmitter.
void schedule_dcch (unsigned char Mod_id, unsigned char User, unsigned short *Freq_alloc_map, unsigned char *User_alloc_map, unsigned short rb_map)
 This routine is used by the NodeB scheduler to allocate resources for dcch channels.

void ue_get_chbch (unsigned char Mod_id, unsigned char CH_index)
 This routine generates a MACPHY_DATA_REQ in order to program UE PHY to receive a CHBCH. This is invoked in TTI $N-1$ for action in TTI $N$. The result is seen by UE MAC in TTI $N+1$.
