WebThe actual PRACH transmission is an OFDM-based reconstruction of a Zadoff-Chu sequence in the time domain. The OFDM modulator is used to position the Zadoff-Chu sequence in the frequency domain (i.e. to place the 6RBs of PRACH transmission in the 6 consecutive RBs starting from some particular physical resource block, denoted n P R B R … WebThe plot shows all the time occasions in which the PRACH can be transmitted. The plot shows all the possible PRACH occasions in the current carrier slot in light blue and the … WebHowever a single UE retransmission of its PRACH cannot overlap its previous PRACH transmission within the same 80 ms period. For example, if UE1’s PRACH is 11.5 access slots long and its first PRACH transmission starts in access slot zero, then the second PRACH transmission for UE 1 must start, at a minimum, in access slot 12. network cable tips
