WebbThe uplink timing control based on timing advance command is applied to PUSCH, PUCCH and SRS in 5G NR . The page mentions messages in which timing advance value is conveyed to the UE by gNB (i.e. 5G NR Base Station). In wireless cellular systems it is required to adjust timing of the uplink frame in order to have alignment with downlink … 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.
