Embodiments of the present invention relate to a method and an apparatus for processing random access in a wireless communication network, and a processing method of a user equipment and an apparatus. The method for processing random access in the communication network includes: the base station receives a first Zadoff-Chu sequence and a second Zadoff-Chu sequence that are sent by a user equipment, a du of the first Zadoff-Chu sequence is smaller than a du of the second Zadoff-Chu sequence; the base station estimates an error range for a round trip delay RTD of the user equipment according to the first Zadoff-Chu sequence, estimates, according to the second Zadoff-Chu sequence, the RTD within the error range for the RTD or a frequency offset of an uplink signal of the user equipment. The problem that the user equipment with a frequency offset accesses a network is solved.
