WIRELESS COMMUNICATION MANAGEMENT METHOD, WIRELESS COMMUNICATION MANAGEMENT SYSTEM, AND WIRELESS COMMUNICATION MANAGEMENT DEVICE
A network includes: a first link between a first STA as a repeater and a first AP as a parent device; and a second link between a second STA as a child device and the first STA. A first transmission time is set during which transmission is permitted to the first link based on a first amount of transmission. A second transmission time is set during which transmission is permitted to the second link based on a second amount of transmission. An entire transmission cycle is determined based on the first transmission time and the second transmission time. A first transmission period and a second transmission period do not overlap in the entire transmission cycle. Wireless communication performed on the first link is limited within the first transmission period. Wireless communication performed on the second link is limited within the second transmission period.

the first transmission time is set on a basis of the first transmission rate, and
the second transmission time is set on a basis of the second transmission rate.
3 . The wireless communication supervising method according to claim 1 , further comprising
calculating a number of packets receivable by the repeater on a premise that the packets are transmitted to the first link in a case where the network is assumed to be used in an environment in which uplink traffic is generated more than downlink traffic, wherein
the first transmission time is set on a basis of a time required to transmit the number of packets on the first link, and
the second transmission time is set on a basis of a time required to upload the number of packets toward the repeater through the second link.
4 . The wireless communication supervising method according to claim 1 , further comprising
calculating a number of packets receivable by the repeater on a premise that the packets are transmitted to the second link in a case where the network is assumed to be used in an environment in which downlink traffic is generated more than uplink traffic, wherein
the second transmission time is set on a basis of a time required to transmit the number of packets on the second link, and
the first transmission time is set on a basis of a time required to download the number of packets toward the repeater through the first link.
5 . The wireless communication supervising method according to claim 1 , wherein a bandwidth wider than a bandwidth used by the second link is allocated to the first link.
6 . The wireless communication supervising method according to claim 1 , wherein
the network includes a plurality of repeaters each relaying the first link and the second link to each other,
the wireless communication supervising method further comprises
setting the entire transmission cycle such that, for at least one of the plurality of repeaters, overlap between the first transmission periods and overlap between the second transmission periods with another repeater are minimized.
7 . A wireless communication supervising system comprising a network including a first link for wireless communication between a repeater and a parent device and a second link for wireless communication between a repeater and a child device, the wireless communication supervising system being configured such that at least one of the repeater or the parent device, or both of the repeater and the parent device execute:
setting a first transmission time during which transmission is permitted to the first link on a basis of a first amount of transmission to be communicated on the first link;
setting a second transmission time during which transmission is permitted to the second link on a basis of a second amount of transmission to be communicated on the second link;
determining an entire transmission cycle on a basis of the first transmission time and the second transmission time, and determining a first transmission period corresponding to the first transmission time and a second transmission period corresponding to the second transmission time not to cause the first transmission period and the second transmission period to overlap each other in the entire transmission cycle; and
