Webbnel (PRACH) for New Radio(5G) and implementing a simulator in matlab. PRACH is a physical uplink channel responsible for random access procedure. I implemented a simulator which comprises of a transmitter and receiver. The design of PRACH must follow 3GPP specification, so that it would be compatible with the industry require-ments. 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.
WebbPhysical Uplink Control Channel The PUCCH resource to use is determined by the ARI in the downlink control signaling, which selects the resource to use from a set of four resources preconfigured in the terminal by RRC signaling.

WebbThis page on LTE PRACH describes LTE Physical Random Access Channel (PRACH).It mentions links for WCDMA PRACH and GSM RACH channel basics. This channel is used to carry random access preambles used for initiation of random access procedure. The … WebbSequence Generation. The pseudorandom sequence used for DM-RS is 2 31-1 length gold sequence. The sequence is generated across all the common resource blocks (CRBs) and is transmitted only in the RBs allocated for data because the sequence is not required to estimate the channel outside the frequency region in which data is not transmitted.
WebbThe available set of PRACH resources is associated with each enhanced coverage level. The preambles that are contained in Random Access Preambles groups for each enhanced coverage level are calculated from the parameters firstPreamble and lastPreamble of …
