Abstract: A method and device for sharing synchronized direct mode time division multiple access (TDMA) timeslots among a plurality of direct mode radios includes monitoring, by a first direct mode radio, other radios' usage of a plurality of available timeslots on a direct mode radio frequency (RF) and, for each received new transmission, storing an indication of the timeslot used by the new transmission and storing a system partitioning identifier associated with the new transmission. Dynamically determining, by the first radio and as a function of the monitoring, a first preferred transmit timeslot determined to be less likely to interfere with the other direct mode radios. Responsive to detecting a request to transmit a new direct mode call, first determining if the first preferred transmit timeslot is available, and if so, transmitting the new call in the first preferred transmit timeslot on the direct mode radio frequency.
