Abstract

A radio system and a data transmission method in a digital radio system where data between two transceivers is transmitted in both directions on the same frequency band in frames consisting of time slots, and where time slots (300, 302) assigned to different directions of transmission are separated from one another in the time domain. To allow effective use of the frequency band available, the number of time slots (300, 302) assigned to the different directions of transmission is varied dynamically.
