US 12,652,138 B2 · Flexible intra-symbol multiplexing of DMRS of different antenna ports for single carrier waveform in higher bands

Abstract

This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for flexible intra-symbol multiplexing of DMRS of different antenna ports for single carrier waveforms. A base station may transmit one or more DMRSs within a symbol and provide an intra-symbol guard interval prior to each of the one or more DMRSs. The intra-symbol guard interval may have a duration that is based on a duration of a CP. A UE may receive the one or more demodulation reference signals DMRSs within the symbol based on the intra-symbol guard interval prior to each of the one or more DMRSs, and perform a channel estimation based on at least one of the one or more DMRSs.

Dependent claims

An apparatus for wireless communication, comprising:

a memory;
and
at least one processor coupled to the memory, wherein the at least one processor is configured to:
transmit, within a symbol, one or more demodulation reference signals (DMRSs);
and
provide an intra-symbol guard interval prior to each DMRS of the one or more DMRSs, wherein the intra-symbol guard interval has a duration that is based on a duration of a cyclic prefix (CP), and wherein the intra-symbol guard interval is separate from the CP.
