1. A method, comprising:

  • generating, by a coordinator of a wireless personal area network (WPAN), a first transmission schedule of a plurality of transmission flows, the first transmission schedule comprising three or more transmission flows involving three or more devices of the WPAN in one channel time block, wherein one of the three or more transmission flows is designated as a primary flow and the others of the three or more transmission flows are designated as non-primary flows, a device with the transmission flow designated as the primary flow to have channel access control and to explicitly activate each non-primary flow, the first transmission schedule for a first super-frame, wherein each of the plurality of transmission flows comprises a transfer of data from a transmitting device of the WPAN to a receiving device of the WPAN;

    wirelessly receiving, by the coordinator of the WPAN, an interference report from one or more devices of the WPAN; and

    based at least on the interference report, generating, by the coordinator of the WPAN, a second transmission schedule of the plurality of transmission flows, the second transmission schedule for a second super-frame, the second super-frame subsequent to the first superframe;

    wherein the first transmission schedule and the second transmission schedule order the plurality of transmission flows differently.
