1. A method of wireless communication, the method comprising:
- determining an estimate of channel quality based at least in part on at least a metric of an observed transmission;
determining a terminal requirement associated with data available for transmission;
selecting a group of access sequences from a plurality of groups of access sequences based at least in part on the determined terminal requirement and comparing the determined estimate of channel quality to a range of channel quality values; and
transmitting an access sequence selected from the selected group of access sequences.

Abstract
An apparatus and method for transmitting an indicator of channel quality while minimizing the use of a broadcast channel is described. A metric of forward link geometry of observed transmission signals is determined. An indicator of channel quality value is determined as a function of the observed transmission signals. An access sequence is selected, randomly, from one group of a plurality of groups of access sequences, wherein each of the plurality of groups of access sequences correspond to different ranges of channel quality values.
