Abstract:
Embodiments of this application provide a signal processing method, a signal transmission method, and an apparatus, which relate to detection technologies, are applied to the field of sensor technologies, and may be applied to intelligent driving, intelligent transportation, surveying and mapping, and intelligent manufacturing. In embodiments of this application, a processing apparatus obtains an echo signal of a detector to obtain a detection result. The detection result may include an image of a detection region and point cloud data of the detection region, or the detection result may be obtained with reference to an image of a detection region and point cloud data of the detection region.
Abstract:
Embodiments of the present invention relate to a data transmission method, an access point, a relay node, and a data node for packet aggregation. The data transmission method for packet aggregation includes: determining an aggregation relay node in a service area, for aggregating a Medium Access Control (MAC) frame that is sent by a data node to an access point (AP) and is forwarded by the aggregation relay node; and receiving an aggregated MAC frame sent by the aggregation relay node, where the aggregated MAC frame is a MAC frame that is sent by the data node and is aggregated by the aggregation relay node. According to the embodiments of the present invention, a relay node is selectively used to aggregate data, so that aggregated packet data quickly reaches a scale for transmission, and the packet data is sent to a destination node within a short time, thereby significantly enhancing quality of service of a delay-sensitive application service.
