Latest Patents
Sandeep Bhat holds a patent for a method titled "Method for FR1 FDD channel state information." This patent proposes a novel method for downlink channel state information (DL CSI) measurement and reporting in FR1 FDD systems. The method involves directing the CSI reference signal (CSI-RS) towards the dominant spatial domain and frequency domain components in the propagation environment. By utilizing partial channel reciprocity, angles and delays in the downlink channel can be derived from uplink channel measurements. The user equipment (UE) is required to measure and provide feedback on the DL CSI corresponding to the dominant angles and delays. The base station (BS) then utilizes this feedback to obtain the precoder in the antenna-frequency domain for transmission over the Physical Downlink Shared Channel (PDSCH). In one embodiment, the UE reconstructs the DL channel across multiple delays using the DL channel estimated from a few beamformed CSI-RS and delay tap indices signaled from the network.
