pix, u mean to say that the same PDCH is used to send signalling as well, the only thing to understand is that while sending signalling it becomes PACCH ( packet associated control channel ).
is it correct , if i say it is much like a TCH being used as a FACCH ( a 20ms block is stolen ) during a handover in voice ?
one more question Pix:
if i study the multiframe of GPRS , out of 52 TDMA frames 2 are PTCCH ( for sending TA information to MS using GPRS ) and 2 frames are idle frames……what for these idle frames are used ??
