Abstract
A master node (11) transmits a bandwidth extension instruction including an extension duration DEX, an extension time slot number NEX, and an extension time TEX to multiple slave nodes (12). The master node (11) and the multiple slave nodes (12) execute a bandwidth extension process of modifying a communication frame such that the start time of the following cycle following the cycle designated by the extension time TEX is advanced by the extension duration DEX, the time slot identified by the extension time slot number NEX is extended by the extension duration DEX, and the time slot identified by the shortening time slot number NSH is shortened by the extension duration DEX. The master node (11) and the slave nodes (12) communicate with each other using the assigned time slots.
Claims8
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.
A non-transitory computer-readable recording medium storing a program, the program causing a computer of a master node in a time division multiplexing communication system for communication using a communication frame containing time slots, to
- transmit a bandwidth extension instruction to slave nodes, the bandwidth extension instruction including an extension duration, an extension time slot number, and an extension time,
- advance a start time of a following cycle following a cycle designated by the extension time by the extension duration,
- extend a time slot identified by the extension time slot number by the extension duration, and
- shorten a time slot identified by a shorting time slot number by the extension duration.
A non-transitory computer-readable recording medium storing a program, the program causing a computer of a slave node in a time division multiplexing communication system for communication using a communication frame containing time slots, to,
- when a bandwidth extension instruction including an extension duration, an extension time slot number, and an extension time is received from a master node,
- advance a start time of a following cycle following a cycle designated by the extensions time by the extension duration,
- extend a time slot identified by the extension time slot number by the extension duration, and
- shorten a time slot identified by a shortening time slot number by the extension duration.
