Abstract
A method, apparatus, and a computer-readable storage medium are provided for partial reciprocity-based adaptive port selection codebook configuration. A method, apparatus, and a computer-readable storage medium are provided for partial reciprocity-based adaptive port selection codebook configuration. In an example implementation, the method may include a user equipment receiving at least one channel state information reporting configuration from a network node, the at least one channel state information reporting configuration including precoding matrix indicator as reporting quantity and an adaptive port selection codebook configuration for the precoding matrix indicator and determining whether partial reciprocity operations for adaptive port selection precoding matrix indicator are activated, the determining based at least on information in a sounding reference signal (SRS) request field of a downlink control information, an active semi-persistent SRS, or a periodic SRS configured by higher layers.
