Initial synchronization
From my understanding of the file lte-ue.c
A main thread: UE_thread always acquire I/Q from the RF board and keep it synchronous This thread calls other threads to process the I/Q In the case of this report, the UE is not yet synchronous with the serving eNB So, the thread calls the dedicated thread to sync (with a full frame of I/Q samples) Waiting the result, it continues to read frame per frame (and trash it), until it gets the result of the sync detection thread When the result is done and positive, it shifts of the right number of I/Q the buffers to be sync with the eNB
A thread: UE_thread_synch try to decode the PBCH in a acquired full frame But, this thread manipulate the RF board: it starts and stop it So, the main thread acquisition become completely corrupted
