Methods, systems, and devices for sounding reference signal (SRS) transmission for massive uplink (UL) transmitters are described. An example method for wireless communication includes determining, by a wireless device, one or more sounding reference signal (SRS) resources, and performing, using one or more SRS ports in the one or more SRS resources, an SRS transmission to a network node. Another example method for wireless communication includes receiving, by a network node from a wireless device, a sounding reference signal (SRS) transmission over one or more SRS resources, wherein the wireless device is configured to determine the one or more SRS resources and perform the SRS transmission using one or more SRS ports in the one or more SRS resources.
