Transmission control method between a plurality of stations

摘要

A communication protocol for use by stations in multiple access telecommunication network wherein communication between stations is via a master station. An upstream channel to the master station is shared by the other stations and has successive frames each consisting of K message slots, each message slot including a data part (DM) for the transmission of a message and M minislots for transmission of slot reservation signals. According to the invention, in case of unsuccessful message transmission and collision between transmission requests, reservation signals for retransmission of a message can be transmitted in any of the KxM minislots of each entire frame. The large number of minislots thereby made available reduces the danger of collision between retransmission requests.
