Abstract: Example signal transmission methods, apparatuses, systems, and computer storage media are disclosed. One example method includes obtaining, by a first detection apparatus, a first moment, where the first moment is a start moment of a first time unit, and the first time unit is used for the first detection apparatus to send a first signal. The first signal is sent by the first detection apparatus based on a first periodicity, where the first signal is used to indicate sending resource information of a detection signal, and the first time unit is further used for a second detection apparatus to receive the first signal.

Abstract: This application provides an information transmission method and apparatus, relates to interference processing of a cooperative radar, and is applicable to internet of vehicles scenarios, such as a vehicle-to-everything V2X scenario, a long term evolution-vehicle LTE-V scenario, and a vehicle-to-vehicle V2V scenario. Therefore, information related to a transmit power can be transmitted through an interface of a radar detection apparatus, and a capability of an automated driving system or an advanced driver assistant system ADAS is improved, to adapt to a variable driving environment. The information transmission method includes: A first detection apparatus receives indication information, where the indication information is used to indicate the first detection apparatus to determine a first transmit power used for transmitting a radar signal; and the first detection apparatus determines the first transmit power based on the indication information.

Abstract: This application relates to the field of wireless communications and self-driving/intelligent driving, and in particular, to the field of collaborative radars. In a solution of this application, a first apparatus receives first information from a second apparatus; the first apparatus determines, based on the first information, priorities of a plurality of time-frequency resources included in a first time-domain range; and the first apparatus determines a first time-frequency resource in the plurality of time-frequency resources, where a priority of the first time-frequency resource is not lower than a priority of a time-frequency resource other than the first time-frequency resource in 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 or avoid interference between radars, especially collaborative radars.
