Abstract
A method is disclosed for establishing wireless random access communications between a base station and multiple mobile terminals. The base station first configures one or more uplink random access opportunities based on predetermined time and frequency variables, and then broadcasts the opportunities. The base station keeps monitoring the uplink random access opportunities so that a random access request made by a mobile terminal using one of the broadcasted opportunities can be detected. Upon receiving the random access request, the base station broadcasts downlink access channels so that a mobile terminal can distinguish which downlink access channel is intended for itself.
