1. A method comprising:

  • receiving transmission segments from at least one device pursuant to a channel-switching schedule, the channel-switching schedule comprising an iteratively-repeated channel sequence;

    wherein the iteratively-repeated channel sequence comprises a plurality of channels, the channel-switching schedule specifying an assigned transmission duration for each channel, the assigned transmission duration for each channel comprising a plurality of time segments;

    for at least one channel of the plurality of channels, detecting a pattern of interference during at least one of a first time segment and a last time segment of the plurality of time segments of the assigned transmission duration; and

    responsive to the detected pattern of interference, automatically shifting, by a specified quantity of time that is less than the assigned transmission duration of the at least one channel, a future channel switch indicated by the iteratively-repeated channel sequence, such that the at least one of the first time segment and the last time segment is added to the assigned transmission duration of a neighboring channel in the iteratively-repeated channel sequence.
