Abstract:
A physical downlink shared channel (PDSCH) region of a subframe may include a reference signal (RS) section that includes one or more of a beam-scanning subsection, a transmit (TX) beam-tracking subsection, a receive (RX) beam-tracking subsection, and a channel state information (CSI) subsection. Reference signals in the TX beam-tracking subsection may be used to update TX analog beams. Reference signals in the RX beam-tracking subsection may be used to update RX analog beams. Reference signals in the beam-scanning subsection may be used to evaluate different combinations of TX and RX analog beams for use in a future directional data transmission. Reference signals in the CSI subsection may be transmitted over quasi-co-located (QCL) antenna ports, and may be used for purposes of channel estimation.
