The main loop uses extensively function pointers to call the right
processing function depending on the split case.
A lot of OAI reduntant global variables contains the same semantic data: time,frame, subframe.
The reworked main loop take care of a uniq variable that comes directly from harware: RF board sampling number.
To use OAI, we need to set all OAI variables that derivates from this timestamp value. The function setAllfromTS() implements this.
### Splitted main level
When FS6 is actived, a main loop for DU (du_fs6()) a main loop for CU case replaces the uniq eNB main loop.
Each of these main loops calls initialization of OAI LTE data and the FS6 transport layer initialization.
Then, it runs a infinite loop on: set time, call UL and DL. The time comes from the RF board, so the DU sends the time to the CU.
This is enough for RF board dialog, but the FS6 is higher in SW layers,
we need to cut higher functions inside downlink and uplink procedures.
As much as possible, the FS6 code is in the directory OPENAIR_DIR/executables. When a given OAI piece of code is small or need complex changes, it is reworked in the file fs6-main.c. The functions naming keeps the OAI function name, adding suffix _fromsplit() or _tosplit().
When this organization would lead to large code copy, it is better to insert modifications in OAI code. This is done in two files:
- openair1/SCHED/phy_procedures_lte_eNb.c: to send signaling channels computation results
- the function sendFs6Ulharq() centralizes all signaling channels forwarding to CU
- openair1/PHY/LTE_TRANSPORT/ulsch_decoding.c: to deal with FS6 user plane split
- sendFs6Ul() is used once to forward user plane to CU
### DownLink
The main procedure is phy\_procedures\_eNB\_TX
The main procedure is phy\_procedures\_eNB\_TX()
This is building the common channels (beacon, multi-UE signaling).
The FS6 split breaks this function into pieces:

subframe2harq\_pid(), generate\_dci\_top(), subframe2harq\_pid()

* the per UE data: pdsch\_procedures() needs further splitting:

* dlsch\_encoding\_all() that makes the encoding: turbo code

unlikely cases can reach redundancy up to x3, when MCS is very
low (negative SINR cases)).

The du user plane data is made of expanded bit in OAI at FS6 split level. 1 pair of functions compact back these bits into 8bits/byte before sending data and expand it again in the DU data reception (functions: fs6Dl(un)pack()).

- it runs
- fill\_ulsch\_cqi\_indication()
* each LTE channel needs to be propagated between CU and DU
* the simplest are the almost static data such as PSS/SSS, that need only static eNB parameters and primary information (frame numbering)
* all the other channels require data transmission CU to DU and DU to CU
* the general design push all the low level processing for these channels in the DU
* the CU interface transports only signal processing results (UL) or configuration to create the RF signal (DL case)
* HARQ is detected in the DU, then only the ACK or NACK is reported to CU
- TBD: either runs in DU or output needs to be transmitted to DU
- fill\_crc\_indication() , fill\_rx\_indication() results need also
to be transmitted or made in the DU
* the CU have to control the power and MCS (modulation and coding scheme)
* the DU performs the signal processing and report only the decoded data like the CQI
* as the DU performas the modulation, scrambling and puncturing, each data packet is associated with the LTE parameters required for these features
* in DL, the CU associates the control parameters and the user plane data
* in UL, the CU sends upfront the scheduled UL data to the DU. So, the DU have the required knowledge to decode the next subframes in time.

How to configure wireshark for dissecting LTE protocols:
- start the wireshark as a sudoers
- goto analyze->enabled prototols
- goto analyze->enabled prototols
=> enable mac_lte_udp and rlc_lte_udp
- goto edit/preferences and expand Protocols
- select UDP and check "try heuristic sub-dissectors first"
- select MAC-LTE, and check all the options (checkboxes), and set the "which layer info to show in info column" to "MAC info"
- select RLC-LTE, and check all the options except the "May see RLC headers only", and set the "call PDCP dissector for DRB PDUs" to "12-bit SN". Optionally you may select the sequence analysis for RLC AM/UM.

How to use
- start eNB or UE with option -W (or -P if you want to make a pcap file)
- capture on local interface "lo"
- filter out the ICMP/DNS/TCP messages (e.g. "!icmp && !dns && !tcp")
How to use
- start eNB or UE with option --opt.type wireshark
--opt options are:
--opt.type none/wireshark/pcap
--opt.ip 127.0.0.1 to specify the output IP address (default: 127.0.0.1)
output port is always: 9999 (to change it, change constant: PACKET_MAC_LTE_DEFAULT_UDP_PORT in OAI code)
--opt.path file_name to specify the file name (pcap)
- capture on local interface "lo"
- filter out the ICMP/DNS/TCP messages (e.g. "!icmp && !dns && !tcp")
