Claim
1. A method for transmitting, by a network node, control signaling, comprising:
determining that a physical downlink shared channel (PDSCH) transmission scheme for a component carrier accessed by a user equipment (UE) is:
a user equipment-specific reference signal (UE RS) based non precoding matrix indicator (Non-PMI) feedback transmission scheme by determining antenna ports corresponding to the UE RS wherein a Non-PMI feedback transmission scheme is a transmission scheme where no PMI is fed back by a UE; and
