Abstract

This application provides one or more resource indication methods, terminal devices, and network devices. An example method includes: receiving, by the terminal device, the first indication information, and determining time domain positions of a demodulation reference signal (DMRS) based on the mapping type of the physical shared channel and with reference to a position index of the last symbol occupied by the physical shared channel or a quantity of symbols occupied by the physical shared channel in the resource unit. The position index of the last symbol occupied by the physical shared channel in the resource unit corresponds to the first type, and the quantity of symbols occupied by the physical shared channel in the resource unit corresponds to the second type.
