Abstract
Official abstract text for this publication.
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 indicators 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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, comprising: receiving in a feedback process, at a base station forming at least one cell having a coverage area that at least partially overlies a coverage area of an underlying cell, a plurality of indicators from a plurality of user equipment in the at least one cell, each value of an indicator corresponding to one or more entries of a codebook the corresponding user equipment recommends to be used for transmission to the user equipment; assign…
