Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, a sounding reference signal (SRS) configuration that indicates a reference group among multiple antenna groups of an antenna array associated with the UE. The UE may transmit an SRS using one or more antennas in the reference group. The UE may transmit, to the base station, a correlation report that indicates an inter-group correlation between the multiple antenna groups associated with the UE. The base station may estimate a channel matrix for the multiple antenna groups based at least in part on the inter-group correlation and measurements of the SRS that is transmitted using the one or more antennas in the reference group. Numerous other aspects are described.
