Abstract
Methods and apparatuses are provided for configured grant (CG) type 1 (CG1)-physical uplink shared channel (PUSCH) transmission. A method includes receiving, via a radio resource control (RRC) configuration, an indication of one or more CG1-PUSCH transmissions for demodulation reference signals (DMRS) bundling; determining, based on a sounding reference signal (SRS) resource indicator (SRI), a precoding matrix for a CGI-PUSCH transmission; processing a DMRS using the determined precoding matrix; and transmitting the processed DMRS across bundled DMRS resources of a set of CG1-PUSCHs, based on the indication. The indication includes a duration in terms of slots over which to perform the DMRS bundling.
