Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network entity may obtain a singular value decomposition (SVD) precoding vector that is based at least in part on backscatter associated with a reference signal transmitted by the network entity. The network entity may apply the SVD precoding vector to an output signal. The network entity may transmit the output signal based at least in part on a set of antennas. Numerous other aspects are described.
