Disclosed is a broadcast implementation method, comprising: a first device receiving a broadcast frame sent by a coordinator, the broadcast frame comprising a response instruction field which is used for instructing a plurality of devices in an LR-WPAN to make responses in sequence; and if it is determined that it is necessary to make a response to the broadcast frame according to the response instruction field, the first device acquiring a response back-off time according to the response instruction field, and sending a response frame when the response back-off time is reached. Also disclosed are a broadcast implementation apparatus and an LR-WPAN. By means of the technical solution of the present invention, a coordinator can designate some devices needing communications to make responses in sequence via a response instruction field in a broadcast frame, so that not only the resource utilization rate and communication efficiency of the coordinator can be improved, but also a response conflict between devices can be avoided, thereby improving the channel utilization rate and performance of an LR-WPAN. |
