Abstract
Machine-readable media, methods, apparatus and system for electrical downtilt adjustment in a multiple input multiple output system are disclosed. In some embodiments, an apparatus may comprise an electrical downtilt module to determine an electrical downtilt angle for an antenna port selected from a number of antenna ports based on information from an user equipment (UE); and a codebook module to select a codeword corresponding to the antenna port from a codebook and calculate a weight of an antenna array of the eNB through inputting the electronic downtilt angle into the codeword, wherein the codebook has a first number of codewords, each of the codewords having a second number of elements to represent the weight of the antenna array, and wherein each of the codewords corresponds to each of the antenna ports and each of the elements corresponds to each antenna of the antenna array.
