Claim 0:
1. A method of performing wireless communications, the method comprising:
receiving, by a user equipment (UE), a Physical Random Access Channel (PRACH) configuration from a base station, the PRACH configuration indicating a first cyclic prefix (CP) length for a PRACH channel that corresponds to the PRACH configuration;
transmitting, by the UE, one or more uplink channels interlaced in a frequency domain with the PRACH channel, the PRACH channel allocated to multiple spaced resource blocks of a block interlace structure in the frequency domain;
receiving, by the UE, a second PRACH configuration from the base station, the second PRACH configuration indicating a second CP length for the PRACH channel; and
transmitting, by the UE, the one or more uplink channels with an adjusted CP length interlaced in the frequency domain with the PRACH channel, wherein a CP length of the one or more uplink channels is adjusted from an initial CP length to the adjusted CP length that matches the second CP length of the second PRACH configuration, and wherein the PRACH channel and the one or more uplink channels are aligned;
wherein adjusting the CP length of the one or more uplink channels comprises adjusting CP lengths of multiple uplink channels to match the second CP length of the second PRACH configuration.
