A method includes receiving a number of indicators from a number of UEs. Each value of an indicator corresponds to entry(ies) of a codebook the corresponding UE recommends to be used for transmission. The method includes assigning the UE to a number of groups, including a first group of UEs having values of indicators corresponding to first codebook entries that when applied to an antenna array produce a pattern in elevation that steers a beam away from an underlying cell, and a second group of UEs having values of indictors corresponding to second codebook entries that are different from the first codebook entries. The method includes transmitting, in a first set of RBs having a first characteristic, to the UEs in the first group and transmitting, in a second set of RBs having a second, different characteristic, to the UEs in the second group. Apparatus and program products are disclosed. |
