Example communication stations and methods for transmitting on a random access channel (RACH) in wireless networks are disclosed herein. An example method for transmitting on an enhanced RACH by a device such that an initial access burst is received in a single time slot by a wireless network involves determining a timing advance, the timing advance being associated with a serving cell. The example method also involves transmitting, using the determined timing advance, the initial access burst, on the enhanced RACH, that includes at least one of an identifier or user data.
