Methods, apparatus, and processor-readable storage media for generating transmission arrangements for device group communication sessions are provided herein. An example computer-implemented method includes determining a transmission ordering of at least a portion of multiple devices in a designated group with respect to transmitting data packets during at least a portion of a communication session, wherein the transmission ordering comprises device identifiers, attributed to at least a portion of the multiple devices, assigned to sequential transmission slots; determining a scheduled distribution of multiple data packet types transmitted by at least a portion of the multiple devices across the sequential transmission slots, wherein the scheduled distribution comprises an identification of a respective one of the multiple data packet types assigned to each of the sequential transmission slots; and participating in the communication session in accordance with (i) the transmission ordering and (ii) the scheduled distribution of the multiple data packet types.
