MUMBAI, India, Aug. 17 -- Intellectual Property India has published a patent application (202647096399 A) filed by Google LLC on August 10, 2026, for Channel State Information Feedback For Coherent Joint Transmission Calibration.
Inventors include Zhang, Yushu; and Liou, Jia-Hong.
The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: Systems, methods, and apparatuses include techniques for providing channel state information (CSI) feedback for coherent joint transmission (CJT) calibration. A user equipment (UE) (130) receives, from a network entity (120), at least one CSI report configuration that configures the UE to report at least one of a time offset (TO), a frequency offset (FO), or a phase offset (PO) associated with one or more CSI reference signal (CSI-RS) resources. The UE transmits, to the network entity, at least one CSI report indicating the at least one of the TO, FO, or PO for the one or more CSI-RS resources based on a reference CSI-RS resource. In some aspects, the one or more CSI-RS resources include a first CSI-RS from a first transmission and reception point (TRP) and a second CSI-RS from a second TRP.
