Abstract: A method for enabling full duplex individual calls in repeater mode between two subscriber units (SUs) in a N:1 slotting ratio time division multiple access (TDMA) radio system includes receiving a request for a full duplex individual call from a first SU identifying a second SU as a target of the call. Determining to grant the request and subsequently assigning a first time slot of the N time slots on a first single frequency for one of inbound and outbound transmissions for the call between an assigned second repeater and the first SU and a second time slot on the first single frequency for the other of inbound and outbound transmissions for the call between the assigned second repeater and the first SU. Further, a grant message is transmitted to the first SU indicating the assigned first single frequency and assigned first and second time slots.
