Wireless transfer device and method for control of wireless transfer band
First Claim
1. A wireless transfer device, comprising:
- a memory storing instructions;
one or more processors configured to execute the instructions to;
determine a transfer band for a packet signal transmitted to a wireless transfer path, on the basis of a result of a comparison of communication quality information pertaining to wireless communication, and a predetermined band control threshold value which is a standard for changing the transfer band;
determine a modulation scheme to be applied to the wireless transfer path, on the basis of a result of a comparison of the communication quality information and a predetermined modulation control threshold value which is a standard for changing the modulation scheme;
secure the determined transfer band in the wireless transfer path, and output the packet signal; and
perform a modulation process on the packet signal, on the basis of the determined modulation scheme,wherein the band control threshold value and the modulation control threshold value are set to be different values, to create a time lag between an operation for changing the transfer band and an operation for changing wireless transfer capacity of the wireless transfer path, the wireless transfer capacity being changed in conjunction with the changing of the modulation scheme.

Abstract
A wireless transfer device (100) is provided with: a transfer band control unit (13) for deciding upon a transfer band, on the basis of the result of a comparison of communication quality information pertaining to wireless communication, and a predetermined band control threshold value; a modulation scheme control unit (14) for deciding on a modulation scheme, on the basis of the result of a comparison of communication quality information and a predetermined modulation control threshold value; a transmission process unit (11) for controlling the transfer band for packet signals on the basis of the transfer band decided upon by the transfer band control unit (13), and outputting packet signals; and a wireless transceiver unit (12), for performing a modulation process on the packet signals output by the transmission process unit (11), doing so on the basis of the modulation scheme decided upon by the modulation scheme control unit (14). The band control threshold value and the modulation control threshold value are different values. In so doing, loss of high-priority packet signals, as well as transient fluctuations of transfer delay time, are avoided.
