Abstract: Methods and apparatuses for determining HARQ timing in a communication system supporting Carrier Aggregation (CA) are provided. A method for receiving, at a BS, a HARQ feedback from a UE in a communication system supporting CA of a Pcell and at least one Scell is provided. The Pcell and Scell support either FDD or TDD. The method comprises: transmitting a downlink physical channel through one of the Pcell and Scell; receiving the HARQ feedback corresponding to the downlink physical channel of the Pcell at a first timing predetermined for the Pcell; and receiving the HARQ feedback corresponding to the downlink physical channel of the Scell at a second timing. The second timing is determined according to one or more of duplex modes of the Pcell and the Scell, a scheduling mode of the Scell, and predefined rules.

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.
