What changed
USPTO published patent application US20260100803A1 for glue reference signal (gRS) design in wireless communication systems, filed October 7, 2024 (Application No. 18908423). The invention covers methods and apparatuses for obtaining and sending reference signals across multiple time spans to maintain phase continuity across SLIV gaps and within SLIVs, optimizing channel estimation across multiple coherent DMRS ports in a CDM group.
Manufacturers of wireless communications equipment and semiconductor firms developing 5G/6G modem technology should monitor this application for potential prior art implications and freedom-to-operate considerations in the reference signal design space.

Abstract
This disclosure provides methods and apparatuses for maintaining phase continuity and optimizing channel estimation in wireless communication systems using multiple coherent demodulation reference signal (DMRS) ports through a glue reference signal (gRS). In various examples, an apparatus for wireless communication such as a UE or network entity may obtain or send, in a first time span, a first reference signal associated with multiple coherent ports in a code division multiplexing (CDM) group; obtain or send, in a second time span prior to the first time span, a second reference signal for compensation of a phase change across a gap between start and length indicator values (SLIVs) or within an SLIV; obtain or send, in the second time span, a third reference signal; and obtain or send a shared channel based on these signals. The methods and apparatuses provide enhanced phase continuity and accurate channel estimation, improving system performance and efficiency.
