Embodiments of the present invention provide a method, a base station, and a user equipment for PRACH access. The method includes: determining a PRACH sequence group used by multiple base stations, where the multiple base stations use a same cell identity and include a macro base station and at least one pico base station, the PRACH sequence group includes k1 first PRACH sequences, k2 second PRACH sequences, k3 third PRACH sequences, k4 fourth PRACH sequences, k5 fifth PRACH sequences, and k6 sixth PRACH sequences, k1 and k4 are positive integers, and k2, k3, k5, and k6 are nonnegative integers; and sending an indication parameter of the PRACH sequence group to the UE for the UE to randomly access a network, where the indication parameter is used for indicating the first PRACH sequences to the sixth PRACH sequences. In the embodiments of the present invention, the PRACH sequence group used by multiple base stations includes the first PRACH sequences to the sixth PRACH sequences and is not limited to three types of PRACH sequences, thereby reducing the fierceness of contention access to a PRACH. |
