Abstract:
The present invention provides a method involving a configurable random access channel structure. One embodiment of the method includes generating a random access channel burst that includes a cyclic prefix and a selected number of repetitions of a preamble. The number of repetitions is selected based on at least one of a cell radius and a radio transmission frequency. This embodiment of the method also includes transmitting the random access channel burst over an air interface.
