1. A method for establishing random access communications between a base station and one or more mobile terminals, the method comprising:

  • configuring one or more uplink random access opportunities based on time and frequency variables;

    broadcasting the uplink random access opportunities;

    monitoring the uplink random access opportunities for detecting a random access request; and

    providing one or more down link access channels to the mobile terminals making the random access requests, wherein random access requests from multiple mobile terminals occupy different uplink random access opportunities or are modulated by different modulation sequences for reducing collision.
