1. A method for wireless communications, comprising:identifying that a random access channel (RACH) procedure is to be performed;
receiving, at a user equipment (UE), an indication of a subcarrier spacing to be used for the RACH procedure; and
determining, based at least in part on the subcarrier spacing, a number of symbols that the UE is to wait between a last symbol of a random access response (RAR) window in which no RAR is received and a retransmission of a RACH message
receiving, an RAR
transmitting a Message 3 response after a time interval, the time interval being a numerological maximum of the time values, including a minimum time gap T, represented in absolute time, and the output N of Equation 1 as follows:
where Ni is representative of the smaller of the tone spacing between Msg2 and Msg3 and S represents a fixed number of symbols.
