    Abstract: A TDMA communications system has a main carrier and at least one secondary carrier, each carrier having timeslots which may be used as traffic channels. The first timeslot of the main carrier is reserved for the main control channel whilst the other timeslots are, when traffic loading allows, reserved for synchronisation words (SYNC) and system information (SYSINFO), thereby enabling, for example, mobile phones to quickly synchronise with base stations. In an attempt to keep the main carrier timeslots free, channels are allocated to the carriers according to a predefined sequence, whereby an attempt is first made to put traffic onto the secondary carriers, the main carrier only being used if this attempt fails. Also mentions "freeing-up" the main carrier's traffic carrying timeslots, when timeslots become available on the secondary carriers, by reallocating them to the secondary carriers.
