Reference signal transmission method, message transmission method, transmission resource determination method and device

摘要

Embodiments of the present application disclose a reference signal transmission method, a message transmission method, a transmission resource determination method and an apparatus. When the first device needs to transmit the reference signal, the first device relates to the transmission resource used to transmit the reference signal from the slot based on the time domain resource parameter of the reference signal. Transmission resource information may be determined, where the transmission resource information may include symbol positions of transmission resources in slots and/or spatial domain resources on symbols within the transmission resources. The transmission resource for transmitting the reference signal can be dynamically determined based on the time-domain resource parameter of the reference signal, as compared with the conventional method in which the reference signal can be transmitted only at a fixed position. .. This can reduce the probability of colliding with the transmission of another message during the transmission of the reference signal. Further, the transmission resource of the reference signal can be determined. If the first resource has a time domain portion that overlaps the second resource, the first device may send only a portion of the reference resource, or may skip sending the reference resource, This improves the transmission performance of the first device.
