ABSTRACT:
The present invention provides a method for transmitting and receiving random access channel messages in an extended range wireless communication system. One embodiment of the method may include accumulating, at a base station, signal energy received during a first portion of a transmission time interval. The method may also include accumulating, at the base station, signal energy received during a second portion of the transmission time interval. The first and second portions are offset from the start or end of the transmission time interval by selected delay intervals. The method may further include detecting the message(s) based on the signal energy accumulated during the first and second portions of the transmission time interval.
