Abstract:
A transmitting radio node ( 10 ) precodes a transmission from a one-dimensional antenna array ( 12 ) to a receiving radio node ( 50 ). The array ( 12 ) includes co-polarized antenna elements ( 14 ) aligned in the array's only spatial dimension. The transmitting radio node ( 10 ) precodes the transmission from each of different subarrays ( 34 a,  34 b ) of the antenna elements ( 14 ) using a coarse-granularity precoder that is factorizable from a multi-granular precoder targeting the given spatial dimension of the array ( 12 ) at different granularities, so as to virtualize the subarrays ( 34 a,  34 b ) as different auxiliary elements ( 38 a,  38 b ). The transmitting radio node ( 10 ) also precode the transmission from the different auxiliary elements ( 38 a,  38 b ) using one or more finer-granularity precoders that are also factorizable from the multi-granular precoder. In this case, the coarse granularity precoders and the one or more finer-granularity precoders are represented within one or more codebooks ( 26 ) used for said precoding.

Claim (Index 5):
The method of  claim 3 , wherein transmitting the precoded, auxiliary-elements reference signal comprises transmitting the precoded, auxiliary-elements reference signal more often than transmitting the full-elements reference signal.
