A load amount for reference signals from one or more wireless devices in communication with an access node is determined and compared with load level criteria. When the load amount meets or exceeds the load level criteria, the one or more wireless devices are directed to transmit reference signals using a subband mode of transmission. A subband quality is determined for a plurality of subbands available for the one or more wireless devices and a subband for reference signal transmission is selected from the plurality of subbands based on channel quality criteria. Wireless transmission, such as from an access node, to the one or more wireless devices is scheduled utilizing beamforming based on the reference signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for controlling a reference signal mode to facilitate beamforming","description":"Systems and methods are described for controlling a reference signal mode to facilitate beamforming.
