Abstract

Methods, systems, and devices for wireless communications are described. A network entity may generate a set of beamforming weights for a lens antenna associated with the network entity. Further, the network entity may generate the set of beamforming weights based on a convergence location corresponding to a target coverage area of a cell supported by the network entity. The convergence location may be based on the target coverage area and on one or more parameters of the lens antenna. As such, the network entity may transmit, via a set of antenna elements of the lens antenna, a signal to a user equipment (UE) in accordance with the set of beamforming weights for the lens antenna such that the signal may be spatially distributed within the target coverage area of the cell.
