Abstract
A hybrid DSMA-CR/CDMA methodology provides efficient access to one of a group of packet channels in a spread spectrum wireless communication network. The base station broadcasts status information as to the availability and/or available data rates for each packet channel or group of channels. Each mobile station uses the status information to select an available channel and/or a channel with sufficient data rate. The mobile station then starts transmission of a series of access preambles, each of which contains a signature corresponding to the selected channel. The mobile station transmits the preambles at increasing power levels. When the base station detects a preamble transmission, the base station responds with a corresponding acknowledgement essentially permitting the mobile station to send its packet data along with any closed-loop power control information over the selected channel.
