Abstract: Example reference signal transmission methods and apparatus are described. One example method includes that a first node maps a reference signal to a first transmission resource and sends the reference signal. The first transmission resource is included in a second transmission resource used by the first node to send data, and the second transmission resource includes a first symbol and at least one subcarrier corresponding to the first symbol. The first transmission resource includes at least one of an Mth subcarrier or an Nth-to-last subcarrier in the at least one subcarrier corresponding to the first symbol, and M and N are preset, specified in a protocol, or configured. The reference signal is used to determine phase information of a channel.

Abstract: A data transmission method includes: A slave node transmits first data to a master node on a first time domain resource in a first time domain resource unit by using a first frequency domain resource. The slave node transmits second data in the target service to the master node on a third time domain resource in a second time domain resource unit using a second frequency domain resource. The first time domain resource unit is adjacent to the second time domain resource unit in a time domain. The first time domain resource unit sequentially includes, in the time domain, the first time domain resource, a first guard period, a second time domain resource, and a second guard period. The second time domain resource unit sequentially includes, in the time domain, the third time domain resource, a third guard period, a fourth time domain resource, and a fourth guard period.

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.
