Abstract: Provided are a signal transmission method and apparatus, and a storage medium. The method comprises: determining a first determination mode and/or a second determination mode, wherein the first determination mode is a mode for determining first SRS transmission corresponding to an uplink signal, and the second determination method is a mode for determining a first antenna port corresponding to the uplink signal; and transmitting the first determination mode and/or the second determination mode to a UE, and the UE determines the first SRS transmission according to the first determination mode, and/or determines the first antenna port according to the second determination mode, and transmits the uplink signal according to the first SRS transmission and/or the first antenna port. Therefore, the present application can solve the defects in the prior art of a transmission scheme being inflexible and configuration and trigger flexibility of an SRS resource being low due to there being only one antenna port and/or SRS transmission scheme for an uplink signal, thereby reducing the degree of network congestion, and improving the flexibility of signal transmission.

Abstract: The embodiments of the present application relate to the technical field of wireless communication, and provide a signal transmission method and device, which are used to more flexibly indicate the transmission of information when PUSCH uplink transmission is performed. The method comprises: 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. Since there is a correspondence between the transmission information and the first resource information, the transmission information can be determined according to the first resource information, thus the transmission information can be indicated more flexibly.
