Embodiments of this disclosure provide an information transmission method and apparatus and electronic equipment. The information transmission method apparatus is used for transmitting a network topology information frame (TI frame) of network topology information, the apparatus including: a transmitting/receiving unit configured to transmit and/or receive a media access control (MAC) layer frame of a network protocol; the network topology information frame (TI frame) is loaded into a payload of the MAC layer frame. According to this disclosure, transmission modes of the network topology information may be made more flexible.

Information transmission method and apparatus and electronic equipment

Embodiments of this disclosure provide a node diagnosis apparatus and system. The node diagnosis apparatus includes: a first receiving unit configured to receive notifications related to busyness/idleness of channels reported by other nodes; a first transmitting unit configured to, when the first receiving unit receives a first notification related to busyness/idleness of channels reported by a first node and a second notification related to busyness/idleness of channels reported by a second node and the first node and the second node are in different basic service sets, transmit a control signal to the first node and the second node; a second receiving unit configured to receive one or more first parameters reported by the first node and one or more second parameters reported by the second node; and a first determining unit configured to determine that the first node and the second node are exposed nodes when the one or more first parameters and the one or more second parameters satisfy a predetermined condition. With the embodiments of this disclosure, whether a node is an exposed node may be well identified, with complexity of identification being low, and signaling being simple.
