UPLINK PHASE TRACKING REFERENCE SIGNALS FOR MULTIPLE TRANSMITTERS ON UPLINK SHARED CHANNELS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17886978 titled 'UPLINK PHASE TRACKING REFERENCE SIGNALS FOR MULTIPLE TRANSMITTERS ON UPLINK SHARED CHANNELS
Simplified Explanation
The patent application describes methods, systems, and devices for wireless communications that support phase tracking reference signal (PTRS) antenna port configuration and usage for up to eight transmission layers. User equipment (UE) can support up to four PTRS antenna ports and transmit capability signaling indicating the number of supported ports. The network entity can transmit control signaling indicating the number of PTRS antenna ports and their mapping to other ports like sounding reference signal (SRS) ports or demodulation reference signal (DMRS) ports. The UE can also indicate a requested number of PTRS antenna ports.

Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. The described techniques provide for phase tracking reference signal (PTRS) antenna port configuration and use to support a number of transmission layers (e.g., up to eight transmission layers). In some examples, a user equipment (UE) may be able to support up to four PTRS antenna ports. The UE may transmit capability signaling indicating a number of supported PTRS antenna ports (e.g., up to 4). The network entity may transmit control signaling indicating a number of PTRS antenna ports and a mapping between the PTRS antenna ports and other ports (e.g., sounding reference signal (SRS) ports or demodulation reference signal (DMRS) ports). In some examples, the UE may also indicate a requested number of PTRS antenna ports (e.g., which may be the same as or less than the supported number of PTRS antenna ports).
