System and method for sparse beamforming design

摘要

System and method embodiments are provided for sparse beamforming designs. In one embodiment, a method for designing sparse transmit beamforming for a network multiple-input multiple-output (MIMO) system allows a cloud central processing unit to transmit a beam for each of a plurality of user equipments (UEs) in the system. Dynamically forming a cluster of transmission points (TP) for use in forming by optimizing network utility functions and system resources, and the cloud central processing unit sparse beam per UE according to optimization Determining a forming vector and a cloud central processing unit transmitting a message and a first beamforming factor to each TP in a formed cluster associated with a first UE in the plurality of UEs. , Each TP in the formed cluster associated with the first UE is in a first beamforming vector corresponding to the first UE Corresponding to zero entry, and transmitting.
