Methods, systems, and devices for wireless communications are described for implementation of higher rank transmissions (e.g., higher rank line of sight (LOS) schemes) over a given beam direction associated with a selected transmission configuration indicator (TCI) state. According to some aspects, expanded antenna arrays, spatial separation (e.g., distance) between antenna elements, lower carrier frequencies (e.g., associated with frequency range 4 (FR4) systems), etc. may be leveraged to communicate uncorrelated signals (e.g., independent streams across spatial layers) for higher rank transmissions using a given TCI state (e.g., using a single beam direction). Various aspects of the described techniques may provide for higher rank directional communications by a user equipment (UE) (e.g., via uncorrelation in a single UE), higher rank directional communications by select UEs (e.g., via uncorrelation across specific UEs), base station antenna selection for uncorrelation at multiple served UEs, etc.
