Webb13 juni 2024 · PRACH preamble is constructed by concatenating several short sequences, each sequence being of the same length as an OFDM symbol for other NR UL signals. These short sequences can be processed using the same FFT sizes as other UL signals thus avoiding the need of dedicated PRACH Hardware.

WebbSummary von the procedure has: UE selects a “preamble” (a code sequence) and sends it at a random time go a UL channel called Physical Random Access Canal (PRACH). UE will start monitoring and DL channel to see if the base station (gNB) answers the request to join to the network. If not, UE will make a new attempt with the increased power.
