Title:

METHODS AND APPARATUS OF TWO PTRS PORTS DESIGN FOR DFT-S-OFDM PUSCH TRANSMISSION

Document Type and Number:

WIPO Patent Application WO/2024/074074

Kind Code:

A1

Abstract:

Various aspects of the present disclosure relate to methods and apparatus of two PTRS ports design for DFT-s-OFDM PUSCH transmission. The apparatus includes a user equipment (UE) for wireless communication, comprising: at least one memory; and at least one processor coupled with the at least one memory and configured to cause the UE to: generate two Phase Tracking Reference Signal (PTRS) sequences for two PTRS ports, respectively, for a multiple-layer Physical Uplink Shared Channel (PUSCH) transmission with Discrete Fourier Transform spread Orthogonal Frequency Division Multiplexing (DFT-s-OFDM); and map the two PTRS sequences for the two PTRS ports to physical resources for the PUSCH transmission.
