Title:
REFERENCE SIGNAL PATTERN ASSOCIATION FOR CHANNEL ESTIMATION
Document Type and Number:
WIPO Patent Application WO/2024/045148
Kind Code:
A1
Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a control signal configuring a low-density pattern for channel state information (CSI) reference signal (RS) reception for a set of multiple antenna ports. The low-density pattern may indicate a subset of the set of multiple antenna ports for the CSI-RS reception via one or more resource blocks (RBs). The UE may receive a set of multiple CSI-RSs that is based on the low-density pattern. In some cases, the UE, or some other training device, may train an artificial neural network to process the CSI-RSs according to the low-density pattern. The artificial neural network may be an example of a generalized neural network or a neural network specific to one or more low-density patterns. The UE may transmit a CSI report based on processing the CSI-RSs according to the low-density pattern.
