Embodiment Construction

[0018] The making and using of the presently preferred embodiments are discussed in detail below. It should be appreciated, however, that the present invention provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention.

[0019] Included herein is a system and method for implementing a beamforming algorithm to optimize antenna beam patterns to increase coverage and reduce interference. Beamforming is implemented using, for example, vertical beamforming schemes to extend coverage based on user equipment (UE) measurement reports (MRs), user location information, and key performance indicators (KPIs). Beamforming can also be implemented based on user and / or traffic distribution information using, for example, a horizontal beamforming scheme to expand network capacity. This is achieved...

Abstract

Methods are components are included herein for implementing beam shaping algorithms to optimize antenna beam patterns. An embodiment method includes dividing a geographical area into a plurality of geographical bins, setting up a plurality of zones for a cell based on a plurality of boundary thresholds, receiving a plurality of signal measurements from a plurality of user equipments across the geographical bins, classifying the geographical bins into the different zones by comparing the signal measurements to the boundary thresholds of the zones, calculating a plurality of gain adjustments for the corresponding geographical bins in at least some of the zones, and generating a beam shaping pattern based on the gain adjustments.

Description

[0001] The title of the invention submitted on October 5, 2012 is "System and Method for Beam Shaping in a Self-Organizing network (SON)" US non-provisional application number 13 / 646557 and the invention filed on October 6, 2011 entitled "System and Method for Beamforming in Ad Hoc Networks (System and Method for Beam Shaping in a Self-Organizing Network), the contents of which are incorporated herein by reference. technical field [0002] The present invention relates to the field of wireless communications and, in particular embodiments, to a system and method for beamforming in a Self Organizing Network (SON). Background technique [0003] In wireless or cellular networks, manual radio frequency (RF) planning may not be sufficient to accommodate changes in the RF environment, since user equipment (UE), such as mobile phones or smartphones, are often mobile. In addition, the system load changes dynamically when more users enter the network or adjust the quality of service...
