TECHNIQUES FOR CSI-RS RESOURCE CONFIGURATION AND IMPLICIT MAPPING FOR LARGE-PORT CSI

Abstract

Various aspects of the present disclosure relate to techniques for communicating channel state information reference signal (CSI-RS) resource configuration and implicit mapping for large-port CSI. A user equipment is configured to receive a CSI-RS resource configuration that configures a CSI-RS resource associated with a quantity of CSI-RS ports greater than a threshold number of ports, identify at least one resource-element location based at least in part on a rule indicated in the CSI-RS resource configuration, wherein the CSI-RS resource configuration indicates fewer than all resource-element locations for the CSI-RS resource, perform one or more CSI measurements based on the identified at least one resource-element location, and transmit a CSI report comprising at least one of the CSI measurements.
