Method and apparatus for channel measurement and feedback |
| abstract |
Embodiments of the invention provide a method for channel measurement and feedback. The method comprises transmitting a first CSI-RS and a second CSI-RS to a user equipment for vertical CSI measurement, wherein the first CSI-RS is based on antenna configuration of one vertical antenna element mapping to one vertical antenna port, and the second CSI-RS is based on antenna configuration of multiple vertical antenna elements mapping to one vertical antenna port. The method also comprises receiving at least one PMI fed back by the user equipment in accordance with the first CSI-RS and the second CSI-RS. The method further comprises determining a vertical precoding matrix for data transmission based on the at least one PMI. |
