Embodiments of the present disclosure provide a method for improved transmission configurations for phase tracking reference signals (PTRS) associated with demodulation reference signal (DMRS) ports multiplexed with one or more DMRS ports via time domain orthogonal cover codes (TD-OCC). The method includes receiving, from a network element, a first indication indicating whether transmission of a PTRS associated with a first DMRS port associated with a first DMRS is enabled in an apparatus, where the first DMRS port is multiplexed with one or more DMRS ports via TD-OCC. The method also includes determining, based at least in part on the first indication, that the apparatus is enabled to transmit the PTRS. The method also includes, in response to determining that the apparatus is enabled to transmit the PTRS, causing transmission of the PTRS to the network element.
