Abstract

A digital radio system based on the MCI DMCA Standard consists of a fixed network and a number of mobile subscriber units, such as radios or cellular telephones. As a portion of the fixed net- work, Base Repeaters (BRs) provide a plurality of communication channels configured in a Time- Division Multiple-Access (TDMA) fashon. In our example, one frequency is divided into six time slots, each containing 15 milliseconds of data. One of the BRs provides a control channel slot and sev- eral trafftc channel slots, while the remaining BRs provide traffic channel slots only. Mobile radio sys- tem access and control occurs over the control channel. The control channel carries most of the control-related messages in the system including, but not limited to: origination requests, channel assignments, power control, time alignment, system configuration, and system resource availability.
