Abstract: A multi-protocol wireless communications system uses prioritization of isochronous streams to increase the reliability and improve bandwidth utilization. Placement of subevents in an isochronous interval according to link quality reduces fragmentation of the isochronous interval. A method for multi-protocol communications between wireless communications devices using a wireless communications interface includes placing in an isochronous group event, by a first wireless communications device, at least one subevent for each isochronous stream of a plurality of isochronous streams of an isochronous group based on a historical retransmission rate for each isochronous stream of the plurality of isochronous streams. The method may include counting retransmissions for each isochronous stream of the plurality of isochronous streams to thereby determine the historical retransmission rate for each isochronous stream of the plurality of isochronous streams.

Abstract: An isochronous channel extension technique transmits asynchronous data using an isochronous channel to reduce or eliminate latency of asynchronous data transfers when asynchronous events and isochronous events with the same peer conflict. A method includes transmitting by a first device, a first data stream using a first channel and a second data stream using a second channel. The first channel has a first interval of first connection events and the second channel has a second interval of second connection events. The first connection events include a first conflicting connection event conflicting with a second conflicting connection event of the second connection events. A first packet of the first data stream associated with the first conflicting connection event is transmitted in the first conflicting connection event and a second packet of the second channel associated with the second conflicting connection event is transmitted in the first conflicting connection event.
