Now that we covered each layer of LTE protocol stack, it is time to combine all these layers to a complete protocol stack.

 

 

Overall Sequence and Layer Configuration

 

Try to follow the sequence below and combine all the knowledges you have and try to make practical sense out of it. This kind of integration is something not explanined in 3GPP specification and you have to figure out on your own.

 

Couple of bullet points for you to follow up are as follows :

 

i) Which of the sequence requires normal MAC header and which of them does not use any MAC header ?

ii) What is the practical meaning of "No MAC Header" and "Normal MAC Header" ?

iii) Which process use RLC TM mode ? Which Process use RLC UM mode and Which process use RLC AM mode ?

iv) Can you explain the detailed RLC layer behavior of each processes which is using RLC layer ?

v) Which process use PDCP and which does not ?

Downlink Channel Map

 

The diagram you saw above a kind of message flow(event diagram) in time sequence. The diagram shown below is not a time based, but it shows the channel mapping (or data flow across the full protocol stack). Pick one of the message from the diagram shown above and try to find right route for this digram and see how much details you can add.

For example, if you picked the message "RRC Connection Setup", the start point would be "RRC Message msg4".

This is only an example case and Mapping (especiall LoCH No) can vary depending on situations. The point is that it will be really helpful for your troubleshooting or test case creation if you create this kind of table for your case.

Live Network Examples in Full Stack

 

This can a good example in which you can practice on very details of MAC to PDCP in detail. This is a segment of logs between a UE and a live network, meaning it shows what's happening in real network. I captured a log using Intellijudge and Wavejudge from SanJole and reformated so that it is easier to read. (First understand the details of RACH, MAC, PDCP in detail especially about the data structure of each layer and then revisit this and see how much you can make sense out of this).
