MUMBAI, India, Sept. 22 -- Intellectual Property India has published a patent application (202617077790 A) filed by Qualcomm Incorporated on June 24, 2026, for Non-Transparent Small Delay Cyclic Delay Diversity.
Inventors include Lee, Hyojin; Jiang, Jing; Zhang, Yu; Iyer, Sumant Jayaraman; and Sankar, Hari.
The application for the patent was published on September 18, 2026, under issue no. 38/2026.
Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first control signal that indicates a set of delay values corresponding to a set of antenna ports. The UE may receive a first reference signal that has a first delay profile. The first reference signal may be a multi-port reference signal or associated with the multi-port reference signal. The UE may determine a second delay profile for a demodulation reference signal (DMRS) based on the first delay profile of the first reference signal, the set of delay values, and an antenna port mapping between the multi-port reference signal and a set of DMRS. The UE may perform a channel estimation on the DMRS based on the set of delay values and the second delay profile.
