Communication apparatus, communication method, computer program and communication system

A communication apparatus to transmit a plurality of frames in a network, each frame including one or more symbols having a symbol length, the apparatus comprising:

• a data processor that adjusts an inter-frame space between two consecutive frames of the plurality of frames upon determination that the inter-frame space is not an integral multiple of the symbol length;
• and
• a transmitter that transmits the adjusted consecutive frames, wherein
• the plurality of frames include a set of frames associated with a first user, and a frame associated with a second user,
• the data processor adds first user padding information between each consecutive frames included in the set of frames to form a guard interval between the first user padding information and a frame from each of the consecutive frames not including the first user padding information, and
• the data processor adds second user padding information to the frame associated with the second user so that a sum of the length of the frame associated with the second user and the second user padding information is equal to a sum of the length of each frame included in the set of frames associated with the first user, each corresponding first user padding information, and each corresponding guard interval.

A communication system comprising:

• a transmitter to:
• adjust an inter-frame space between two consecutive frames of a plurality of frames, upon determination that the inter-frame space is not an integral multiple of the symbol length, by inserting padding information between the two consecutive frames to form a guard interval between the padding information and a frame of the two consecutive frames not including the padding information, a length of the padding information and the guard interval being equal to an integral multiple of the symbol length, and
• transmit the adjusted consecutive frames;
• and
• a receiver to receive the adjusted consecutive frames.

A communication system comprising:

• a transmitter to:
• acquire an inter-frame space between two consecutive frames from a plurality of frames, each frame including one or more symbols having a symbol length,
• adjust the inter-frame space between the two consecutive frames upon determination that the inter-frame space is not an integral multiple of the symbol length, and transmit the adjusted consecutive frames;
• and
• a receiver to receive the adjusted consecutive frames, wherein
• the transmitter adjusts the inter-frame space by inserting padding information between the two consecutive frames, the padding information having a length equal to an integral multiple of the symbol length.

A method for transmitting a plurality of frames, each frame including one or more symbols having a symbol length, the method comprising:

• adjusting an inter-frame space between two consecutive frames of the plurality of frames upon determination that the inter-frame space is not an integral multiple of the symbol length;
• and
• transmitting the adjusted consecutive frames, wherein
• the step of adjusting the inter-frame space further comprises:
• inserting padding information between the two consecutive frames, the padding information having a length equal to an integral multiple of the symbol length.
