5G NR PRACH Power Control: MSG1 Tx Power – Open Loop Power
In any wireless System, when a device (UE) needs to get access it has to send a signal or preamble (MSG1) to base station (gNB), then energy is needed. One […]
5G NR RA-RNTI Calculation
A 5G UE picks a random preamble for RACH procedure to get the uplink synchronisation. The preamble is referenced with an ID know as RAPID (Random Access Preamble ID). 5G […]
5G NR RACH Preamble Types: Long and Short Preambles
A preamble is send by UE to gNB over PRACH channel to obtain the UL synchronization. Similar to LTE, in 5G NR there are 64 preambles defined in each time-frequency […]
