Abstract
Methods, systems, and devices for wireless communications are described. Generally, a network entity may configure a user equipment (UE) with transmission time interval (TTI) format information, and the UE may determine time domain windows for joint channel estimation based thereon. The network entity may also configure the UE with an association between one or more demodulation reference signal (DMRS) ports and one or more phase-tracking reference signal (PTRS) ports. The UE may maintain phase continuity across physical uplink channel transmissions within a time domain window in which a PTRS is scheduled when DMRS and PTRS are transmitted via the associated DMRS and PTRS ports (e.g., when the PTRS-DMRS association is identical across the time domain window). In some cases, the UE may not maintain phase continuity across multiple physical uplink channel transmissions occurring within a time domain window when a PTRS is also scheduled within the time domain window.
