Abstract: Disclosed is a method and system for use of orthogonal coding to manage control channel load. Based on evaluation of downlink air interface load, a base station dynamically toggles use of orthogonal coding of downlink control information (DCI) messages for transmission on a downlink control channel. When downlink load is high, the base station may responsively operate in a state in which the base station orthogonally codes DCI messages to facilitate transmitting multiple DCI messages per set of resource elements on the downlink control channel, possibly boosting transmission power in those resource elements to help facilitate successful transmission. Whereas, when downlink load is not high, the base station may responsively operate in a state in which the base station does not orthogonally code DCI messages and thus sends just one DCI message per set of resource elements.
