Abstract:
A transmitting radio node precodes a transmission from an antenna array to a receiving radio node. The array includes co-polarized antenna elements aligned in a given spatial dimension of the array. The transmitting radio node precodes the transmission from different subarrays of the antenna elements using respective coarse-granularity precoders that are factorizable from a multi-granular precoder targeting the given spatial dimension of the array at different granularities, so as to virtualize the subarrays as different auxiliary elements. The transmitting radio node also precode the transmission from the different auxiliary elements 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 used for said precoding

Claim (Index 15):
A method for receiving a transmission from an antenna array that includes co-polarized antenna elements aligned in a given spatial dimension of the array, wherein the antenna array is associated with a transmitting radio node, wherein the method is performed by a receiving radio node and comprises:\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:\n a multi-granular precoder in a multi-granular codebook targeting the given spatial dimension of the array at different granularities, each multi-granular precoder in the codebook comprising a combination of a coarse-granularity precoder and one or more finer-granularity precoders; or \n a coarse-granularity precoder in a coarse-granularity codebook and one or more finer-granularity precoders in one or more finer-granularity codebooks, the combination of which corresponds to a multi-granular precoder targeting the given spatial dimension of the array at different granularities; \n 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 one or more finer-granularity precoders 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.
