-Preamble?Index-6bits;
-PRACH?Mask?Index-4bits;
The bit that-CarrierIndex-3bits//employing is reserved carries the up-link carrier numbering.
UE by send random access code on the uplink random access resources of Physical Random Access Channel index appointment, carries out the uplink random access procedure on the corresponding up-link carrier of up-link carrier numbering then; ENB sends accidental access response on descending carrier after detecting random access code, so that UE inserts this eNB.
