    Abstract: Apparatus and methods are provided for port selection codebook configuration. A user equipment (UE) may receive, from a base station, an indication of parameter settings of a port selection codebook. The port selection codebook includes a port selection matrix W1, a combinational coefficient matrix W2, and a frequency basis selection matrix Wf. Based at least in part on the parameter settings, the UE selects L CSI-RS ports, Mv frequency basis from a window of N consecutive frequency basis; and up to beta*L*Mv entries per layer, where beta is a percentage of the L*Mv entries per layer. The UE reports one or more of the port selection matrix W1, the up to beta*L*Mv entries in the combinational coefficient matrix W2 per layer, and the frequency basis selection matrix Wf to the base station.
