1. A method for transmitting from user equipment (UE) to base stations (nodeB) in a cellular network, comprising:
maintaining a fixed set of preamble parameter configurations for use across various cells within the cellular network;
receiving at a UE located in a cell a configuration number transmitted from a nodeB serving the cell;
selecting a preamble parameter configuration specified by the received configuration number from the fixed set of preamble parameter configurations; and
transmitting a preamble from the UE to the nodeB using the preamble parameter configuration indicated by the configuration number.
