Abstract
A communications terminal receives a data communications signal via a random access channel. A processor searches for data bursts in a first time-slot that include one of a first set of signature sequences assigned to the first time-slot. When a data burst A in the first time-slot includes one of the first set of signature sequences, the data burst A in the first time-slot is an initial burst of a message from a first communications terminal. The processor determines whether a second time-slot includes a data burst B that includes the one signature sequence. When the second time-slot includes the data burst B, the message is a multi-burst message and that the data burst B is a second burst of the multi-burst message. When the second time-slot does not include the data burst B the message is a single-burst message that has been completed via the first time-slot.
