Abstract
A method for direct mode channel access in a time division multiple access (TDMA) system includes: assigning a radio operating in the TDMA system to transmission on a first time slot of a direct mode channel; initiating a request for a direct mode transmission on the direct mode channel; determining, by the radio, whether there is communication activity present in the first time slot or a second time slot of the direct mode channel; aligning, by the radio, to a selected slot timing based on the determining step; and transmitting, by the radio, with the selected slot timing on the first time slot.
