Patent abstract
Embodiments of the invention provide a method and apparatus for initiating a telecommunications uplink from a mobile terminal to a telecommunications network. A preamble signal is transmitted from the mobile terminal to the network in accordance with a transmission parameter of the mobile terminal. The parameter is changed and the preamble retransmitted until successful receipt in the network is confirmed. Changing the transmission parameter alters the signal diversity of one or more preambles as received by the base station.
