Abstract
A method implemented on a network node includes receiving an adjustable schedule of transmission start slots, the slots representing opportunities for initiating data transmission by at least one network device on a network, transmitting an expected duration indication in each slot associated with the network node as per the schedule, and adjusting the schedule in accordance with the expected duration for each transmission. A method for virtual carrier sensing includes receiving a schedule of transmission start slots on a network node, the slots representing opportunities initiating data transmission by at least one network device in a network, listening for transmissions by other network nodes according to the schedule, the transmissions indicating an expected length of a current transmission, adjusting the schedule in accordance with the indicating of a data transmission, and ignoring any subsequent transmissions until a next scheduled transmission start slot in accordance with the adjusted schedule.
