Aspects are provided which allow a network entity to consider an identity property for received RS during analog combining or aggregation in order to achieve efficient channel sounding and estimation. The network entity may receive an RS in a time period via a plurality of antenna elements. The network entity may combine, in an analog domain, the RS received via each of the antenna elements based at least in part on weights associated with the antenna elements. At least one weight of the weights changes over the time period, and the weights are elements of a time domain orthogonal cover code or a DFT matrix. As a result of these weights, the network entity may estimate multiple combined or individual channels of antenna elements or groups from one or more RS in one or more symbols, potentially improving UE energy efficiency, efficient resource allocation, and coherency between the antenna elements.
