Abstract
A method of transmitting data packets from a terminal (T) to a gateway receiver (GWR) over a channel shared with other terminals using an unslotted spread spectrum random access protocol, characterized in that transmission is performed at a transmit power level given by the sum of a deterministic term, function of a communication link budget, and of a random term, following a predetermined probability distribution. A method of operating a communication system, based on the method of transmitting data packets. A communication system and a terminal for implementing the methods.
