Abstract
Systems and methods for User Equipment (UE)-assisted precoder selection are provided. In one embodiment, a method implemented in a base station for transmitting data to a UE includes transmitting, to the UE, Channel State Information Reference Signal (CSI-RS) on two sets of CSI-RS resources; receiving, from the UE, two sets of CSI; estimating a first channel capacity for the codebook-based precoder based on the first set of CSI and a second channel capacity for the non-codebook-based precoder based on the second set of CSI; selecting one precoder from the codebook-based precoder and the non-codebook-based precoder based on the first channel capacity and the second channel capacity; and performing data transmission to the UE using the selected precoder. Embodiments of the proposed solution enable selecting a best precoder from the codebook-based precoder and the non-codebook-based precoder.
