Abstract
A method for communicating a group call within a communication network comprising at least one repeater and a plurality of communication devices includes: receiving at least one preamble slot and at least one synchronization slot from an originator communication device by the repeater and a communication device; operating the communication device to receive one or more calls directly from the originator device via eavesdropping on the repeater uplink channel when a received signal strength indication (RSSI) of the direct preamble and synchronization slots is greater than a threshold; and operating the communication device to receive one or more calls from the originator device via the repeater on a repeater downlink channel of the repeater when the direct RSSI is not greater than the threshold.
