US 2022/0045813 A1 · DMRS BUNDLING SCHEMES FOR UPLINK NON-CODEBOOK TRANSMISSIONS

Abstract

Methods and apparatuses are provided for configured grant (CG) type 1 (CG1)-physical uplink shared channel (PUSCH) transmission. A method includes a user equipment (UE) determining, based on a sounding reference signal (SRS) resource indicator (SRI), a precoding matrix for a CG1-PUSCH transmission, processing a demodulation reference signals (DMRS) using the determined precoding matrix; and transmitting the processed DMRS across bundled DMRS resources of a set of CG1-PUSCHs.
