My information is from 'decoding gsm' master thesis from glendrange, hove, hvideberg (2010) norwegian university of science and technology, page 92, figure 5.4.
I,m getting closer to understand the process of assignment if i understand you correctly now.
I could match the informations from imm.ass (downlink) against the paging response (uplink) on sdcch right? Anyway i still see no way to listen to uplink traffic on sdcch without usrp-hardware.

Where would you have read that in the spec ?

You can't ... I just said so in the previous mails ...
There is no indication in the imm.ass that would allow you to know for
which mobile identity a channel is intended. You can only know if it
matches _your_ request (by matching time and random reference)
