Abstract: Systems, methods, apparatuses, and computer program products for a modified multi-slot random access channel (RACH) transmission, such as an extended coverage RACH (EC-RACH) transmission, are provided. One method includes transmitting, by a mobile station associated with a network, a dual slot hybrid random access channel including a long burst followed by one access burst or including one access burst followed by one long burst. Two consecutive time slots may be used for the random access channel transmission.
