Abstract
Some aspects of this disclosure relate to apparatuses and methods for supporting the transmission of phase tracking reference signals (PTRS) based on an association between one or more PTRS ports and one or more demodulation reference signals (DMRS) ports for a user equipment (UE) having multiple uplink (UL) antenna elements. The UE can receive a downlink control information (DCI) including an association indication contained in an association field of the DCI to indicate an association between one or more PTRS ports and one or more DMRS ports. The association field can have a bit width determined based on an antenna architecture of the UE including the number of UL antenna elements. The UE can further determine a DMRS port associated with a PTRS port based on the association indication contained in the association field and the antenna architecture.
