Examples communicate the CSD mode in a signaling message. Specifically, a CSD mode is set in an access point the sent to a mobile device. The signaling messages may be either a point-to-point message or a broadcast message. The access point or location server may set the current CSD mode from a plurality of mobile devices by crowd sourcing. For example, the plurality of mobile devices may report what CSD mode was detected. Alternative, the plurality of mobile devices may send a channel impulse response (CIR), or the like, to a location server and the location server may determine what CSD mode is currently used by the access point."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Cyclic shift delay detection using signaling","description":"Systems, apparatus and methods for determining a cyclic shift diversity (CSD) mode are presented.
