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. WebbSystem information block 2 carries radio resource configuration information which is common for all UEs. SIB2 information can be divided in following sub categories. Random access channel (RACH) related parameters. Idle mode paging configurations. Uplink physical control channel (PUCCH) and shared channel (PUSCH) configurations.

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. how to set wallpaper in iphone https://ods-sports.com
