1. A first relay apparatus included in a wireless communication system that includes a control apparatus, the first relay apparatus and a second relay apparatus, the first relay apparatus comprising:
one or more processors; and
one or more memories that store a computer-readable instruction for causing, when executed by the one or more processors, the first relay apparatus to:
perform, using a first communication method, communication relay in at least a part of a communication link used for communication conducted by the control apparatus, wherein the second relay apparatus performs communication relay in at least another part of the communication link, and wherein the first relay apparatus performs communication relay in at least a part of a first link, included in the communication link, between the control apparatus and the second relay apparatus; and
transmit, to the control apparatus and using a second communication method different from the first communication method, information indicating that disconnection of a part of a second link, included in the communication link, between the control apparatus and the first relay apparatus is detected.
