1. A signal transmission method, comprising:
determining at least one of a first determination mode or a second determination mode, wherein the first determination mode is a mode for determining a first sounding reference signal (SRS) transmission corresponding to an uplink signal, and the second determination mode is a mode for determining a first antenna port corresponding to the uplink signal; and
transmitting at least one of the first determination mode or the second determination mode to a user equipment (UE), the first determination mode is used for determining the first SRS transmission, or the second determination mode is used for determining the first antenna port, or the first determination mode is used for determining the first SRS transmission and the second determination mode is used for determining the first antenna port, and the uplink signal is transmitted according to at least one of the first SRS transmission or the first antenna port;
wherein the second determination mode comprises:
determining the first antenna port according to an antenna port for one or more SRS transmissions of a fourth SRS resource set, or an antenna port for one or more SRS transmissions of a fifth SRS resource set, or an antenna port for one or more SRS transmissions of a fourth SRS resource set and an antenna port for one or more SRS transmissions of a fifth SRS resource set; or
taking an antenna port for fifth SRS transmission as the first antenna port; or
taking an antenna port for one or more SRS transmissions of a sixth SRS resource set as the first antenna port;
wherein the fourth SRS resource set is an SRS resource set with a given type that unmatched with a transmission mode of the uplink signal;
the fifth SRS resource set is an SRS resource set matched with the transmission mode of the uplink signal;
the fifth SRS transmission is the most recent SRS transmission of an SRS resource indicated by SRI in DCI which schedules the uplink signal, where the SRS resource is prior to a PDCCH carrying the DCI; and
the sixth SRS resource set is an SRS resource set indicated by SRS resource set indication information transmitted by a network device.
