Systems and Methods for PTRS and DMRS Port Association for Transmission of PUSCH on Multiple Beams - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240244612 titled 'Systems and Methods for PTRS and DMRS Port Association for Transmission of PUSCH on Multiple Beams

Simplified Explanation: This patent application describes systems and methods for associating phase tracking reference signal (PTRS) and demodulation reference signal (DMRS) ports for multi-beam physical uplink shared channel (PUSCH) transmissions. A base station can provide PTRS and DMRS port associations to a user equipment (UE) for multiple beams on which the PUSCH is transmitted.

• The patent application introduces a method for associating PTRS and DMRS ports for multi-beam PUSCH transmissions.
• It allows a base station to provide PTRS and DMRS port associations to a UE for different beams.
• The invention includes using a 2-bit downlink control information (DCI) field to provide single beam or multiple beam PTRS and DMRS port associations.
• For non-codebook based transmissions, the UE can independently determine PTRS and DMRS port associations for multiple beams.

Original Abstract Submitted

systems and methods for associating phase tracking reference signal (ptrs) and demodulation reference signal (dmrs) ports for multi-beam physical uplink shared channel (pusch) transmissions are described herein. a base station may provide, to a user equipment (ue), ptrs and dmrs port associations for the multiple beams on which the pusch is transmitted. in some cases, a 2-bit downlink control information (dci) field may be used to alternatively provide single beam or multiple beam ptrs and dmrs port associations to a ue. for non-codebook (ncb) based transmissions, the ue may alternatively determine ptrs and dmrs port associations for multiple beams independently of any ptrs and dmrs port association indicated in dci.
