Various aspects of the present disclosure generally relate to reducing overhead and / or user equipment (UE) complexity when performing independent spatial domain (SD) basis selection in a channel state information (CSI) codebook. For example, a UE may select any SD basis in a codebook for a first layer, and may SD bases selected for additional layers may be restricted to SD bases that are orthogonal to the first SD basis. Furthermore, SD bases that are selected for a layer may be excluded from SD basis selections for subsequent layers, ensuring that different SD bases are selected for each layer.
