Abstract
A signal transmission method and device are disclosed. The method includes: a network side device first determines transmission information that is used for uplink signal transmission and that corresponds to first resource information, then generates transmission indication information according to the transmission information, and finally indicates the transmission indication information to a terminal so that the terminal determines, according to the transmission indication information, transmission information corresponding to an uplink signal on a frequency domain resource, and transmits the uplink signal according to the transmission information.
Claims19
