摘要： The invention relates to a method of feeding back information from a receiver to a transmitter, and also a corresponding receiver, transmitter, system comprising a receiver and transmitter, and computer program products for performing the steps of the receiver and transmitter respectively. The method comprises: receiving signals at the receiver from the transmitter over a wireless multiple-input-multiple-output channel; and, based on the received signals, transmitting back reports from the receiver to the transmitter including a report indicating a pre-coding matrix and a report indicating a rank of the pre-coding matrix. In the event that the report indicating the rank is not transmitted, the receiver instead uses a default rank to determine the report.

A receiver can include a plurality of antennas each for receiving a version of a signal via a different propagation channel and providing that version to a respective input.

The receiver can include channel parameter estimation means, configured to estimate one or more channel parameters on the propagation channels. The receiver can also include selection means configured to select only a subset of said inputs to implement a specific dimensionality of the receiver diversity processing, in dependence on the one or more channel parameters indicative of channel conditions on said propagation channels.
