MIMO FEEDBACK SCHEMES FOR CROSS-POLARIZED ANTENNAS

Title:

MIMO FEEDBACK SCHEMES FOR CROSS-POLARIZED ANTENNAS

Document Type and Number:

WIPO Patent Application WO/2011/073876

Kind Code:

A3

Abstract:

A method includes receiving a Multiple-Input Multiple Output (MIMO) signal over multiple communication channels from an antenna array (40) including a first set of antennas (44A...44D) having a first polarization and a second set of the antennas (48 A...48D) having a second polarization that is orthogonal to the first polarization. First feedback information is calculated relating to first interrelations between the antennas within either the first set or the second set. Second feedback information is calculated relating at least to second interrelations between the first set and the second set of the antennas. The first feedback information is transmitted at a first time/frequency granularity, and the second feedback information is transmitted at a second time/frequency granularity that is finer than the first time/frequency granularity.
