Abstract: A signal transmission method includes: A first node sends a first preamble on a first channel; and the first node transmits a signal frame on the first channel, where the first preamble indicates a type of the signal frame. Because the first preamble transmitted by the first node on the first channel may indicate a type of a signal frame subsequently transmitted by the first node, different types of signal frames are indicated by the first preamble in different scenarios, so that signal transmission requirements in different scenarios can be met. For example, in a ranging scenario, the first preamble may indicate that the signal frame is a ranging frame. An apparatus is configured to perform the transmission method.

Abstract: This application relates to the field of wireless communications and self-driving/intelligent driving/autonomous driving vehicles, and in particular, to the field of collaborative radars. A first apparatus receives first information from a second apparatus. The first apparatus determines, based on the first information, the priorities of a plurality of time-frequency resources included in a first time-domain range. The first apparatus further selects a first time-frequency resource among the plurality of time-frequency resources. The priority of the first time-frequency resource is the highest among the priorities of the plurality of time-frequency resources. A time-frequency resource with a comparatively high priority is selected to send a radar signal, to reduce a probability of a resource collision, and reduce and/or avoid interference between radars, especially collaborative radars.
