Bandwidth Allocation Apparatus And Bandwidth Allocation Method

A relay transmission system that accommodates a communication system configured to perform radio communication according to a TDD scheme, the relay transmission system comprising:

• a traffic information acquisition unit configured to acquire traffic information indicating a traffic amount of communication that a lower-level apparatus performs via a terminating apparatus;
• a traffic amount estimation unit configured to calculate a surplus bandwidth in an uplink from the traffic information;
• and
• a newly-connected terminating apparatus authentication unit configured to set an activation window in which a signal for allowing a newly-connected terminating apparatus to send an authentication request to a terminal station apparatus is transmitted in the surplus bandwidth in the uplink.

A relay transmission system that accommodates a communication system configured to perform radio communication according to a TDD scheme, the relay transmission system comprising:

• a traffic information acquisitor configured to acquire traffic information indicating a traffic amount of communication that a lower-level apparatus performs via a terminating apparatus;
• a traffic amount estimator configured to calculate a surplus bandwidth in an uplink from the traffic information;
• and
• a newly-connected terminating apparatus authenticator configured to set an activation window in which a signal for allowing a newly-connected terminating apparatus to send an authentication request to a terminal station apparatus is transmitted in the surplus bandwidth in the uplink,
• wherein each of the traffic information acquisitor, the traffic amount estimator, and the newly-connected terminating apparatus authenticator is implemented by:
• i) computer executable instructions executed by at least one processor, ii) at least one circuit, or iii) a combination of computer executable instructions executed by at least one processor and at least one circuit.
