Abstract

A method, apparatus and system are provided for use in better optimizing switched beam, wireless communications. In some embodiments, a method is provided that receives a communication over a first wireless reverse link beam, selects a type of beam weighting control, determines a rule according to the type of beam weighting control, and determining a weighting of a forward link beam according to the rule. The method can further determine an energy of the first reverse link beam, and determine a first gain energy ratio based on the first reverse link beam energy, such that the weighting is determined by applying the first gain energy ratio to the rule. Some embodiments further determine a pilot beam configuration, wherein the rule is determined according to the pilot beam configuration and the selected type of beam weighting control.
