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 11):
A method for receiving a transmission from a one-dimensional antenna array that has co-polarized antenna elements aligned in the arrays only spatial dimension, wherein the antenna array is associated with a transmitting radio node, wherein the method is performed by a receiving radio node and is characterized by:\n receiving a first reference signal transmitted from the antenna array; based on measurement of the first reference signal, generating a first type of recommendation that recommends either; a multi-granular precoder in a multi-granular codebook targeting the array's spatial dimension at different granularities, each multi-granular precoder comprising the Kronecker Product of a coarse-granularity precoder and a finer-granularity precoder; or a coarse-granularity precoder in a coarse-granularity codebook and a finer-granularity precoder in a finer granularity codebook, the combination of which corresponds to a multi-granular precoder targeting the array's spatial dimension at different granularities; transmitting the first type of recommendation to the transmitting radio node; receiving a second reference signal transmitted from the antenna array; based on measurement of the second reference signal, generating a second type of recommendation that recommends a finer-granularity precoder factorizable from a multi-granular precoder; transmitting the second type of recommendation to the transmitting radio node; and receiving from the antenna array a data transmission that is precoded based on the first and second types of recommendations.
