Base station, bandwidth allocation method, wireless communication system and terminal

A bandwidth allocation method in a base station that is capable of wireless communication that uses a high frequency band, the method comprising:

• a step of retaining information relating to at least one already-allocated bandwidth, among all bandwidths that are to be used for the wireless communication, in a memory;
• a step of determining whether the already-allocated bandwidth that is the same as a bandwidth which satisfies terminal performance information is present or absent, according to a request for communication from a terminal, which includes the terminal performance information;
• a step of determining whether a non-allocated bandwidth that is the same as the bandwidth which satisfies the terminal performance information is present or absent, in a case where the already-allocated bandwidth that is the same as the bandwidth which satisfies the terminal performance information is absent;
• and
• a step of allocating the non-allocated bandwidth that is the same as the bandwidth which satisfies the terminal performance information, for the wireless communication with the terminal, in a case where the non-allocated bandwidth that is the same as the bandwidth which satisfies the terminal performance information is present.

A wireless communication system comprising:

• at least one terminal;
• and
• a base station that is capable of wireless communication with the terminal, which uses a high frequency band,
• wherein the terminal transmits a request for communication, which includes terminal performance information of the terminal itself, to the base station, and
• wherein the base station
• retains information relating to at least one already-allocated bandwidth, among all bandwidths that are to be used for the wireless communication, in a memory,
• determines whether the already-allocated bandwidth that is the same as a bandwidth which satisfies the terminal performance information is present or absent, according to the request for the communication, which is transmitted from the terminal,
• determines whether a non-allocated bandwidth that is the same as the bandwidth which satisfies the terminal performance information is present or absent, in a case where the already-allocated bandwidth that is the same as the bandwidth which satisfies the terminal performance information is absent, and
• allocates the non-allocated bandwidth that is the same as the bandwidth which satisfies the terminal performance information, for the wireless communication with the terminal, in a case where the non-allocated bandwidth that is the same as the bandwidth which satisfies the terminal performance information is present.

A terminal that wirelessly communicates with a base station that is capable of the wireless communication that uses a high frequency band, the terminal comprising:

• a memory in which terminal performance information of the terminal itself that includes information relating to a bandwidth in which the terminal is operable, among all bandwidths that are to be used for the wireless communication, is retained;
• a processor that generates a request for communication with the base station, which includes the terminal performance information of the terminal itself;
• and
• a communication unit that transmits the request for communication to the base station,
• wherein, in the base station, it is determined whether an already-allocated bandwidth that is the same as a bandwidth which satisfies the terminal performance information is present or absent,
• in a case where the already-allocated bandwidth that is the same as the bandwidth which satisfies the terminal performance information is absent, it is determined whether or not a non-allocated bandwidth that is the same as the bandwidth which satisfies the terminal performance information is present or absent, and
• in a case where the non-allocated bandwidth that is the same as the bandwidth which satisfies the terminal performance information is present, the communication unit receives information relating to the non-allocated bandwidth that is the same as the bandwidth which satisfies the terminal performance information, which is transmitted from the base station, and
• wherein the processor sets information relating to a bandwidth for the wireless communication with the base station, using the information relating to the non-allocated bandwidth that is the same as the bandwidth which satisfies the terminal performance information, which is transmitted from the base station.
