1. A time division multiplexing communication system, comprising:
a master node; and
slave nodes to communicate with the master node using a communication frame containing time slots, wherein
the master node comprises a communicator to transmit a bandwidth extension instruction to the slave nodes, the bandwidth extension instruction including an extension duration, an extension time slot number, and an extension time, and
each of the master node and the slave nodes comprises processing circuitry to modify the communication frame such that,
a start time of a following cycle following a cycle designated by the extension time is advanced by the extension duration,
a time slot identified by the extension time slot number is extended by the extension duration, and
a time slot identified by a shortening time slot number is shortened by the extension duration.
