Abstract
Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support reference signal port association determination for single frequency network (SFN) uplink. For example, a user equipment may receive first control signaling scheduling transmission of sounding reference signals (SRS) from a plurality of SRS resource sets. The UE may receive second control signaling comprising an indication of one or more SRS resources from the plurality of SRS resource sets and scheduling transmission of one or more SFN uplink messages based at least in part on the indication of the one or more SRS resources. The UE may determine a frequency resource association between one or more phase tracking reference signal (PTRS) ports and one or more demodulation reference signal (DMRS) ports of a plurality of DMRS ports based at least in part on a port association rule and the indication of one or more SRS resources.
