Facilitating shared demodulation reference signal design for control channels in a wireless communications system is provided herein. A system can comprise a processor and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations. The operations can comprise evaluating a usage parameter of a mobile device for application of channel demodulation reference signal reuse by the mobile device. In response to a first determination that the usage parameter satisfies a condition relative to a threshold usage parameter, the operations can comprise facilitating a first transmission to the mobile device to implement the channel demodulation reference signal reuse by the mobile device. In response to a second determination that the usage parameter does not satisfy the condition relative to the threshold usage parameter, the operations can comprise facilitating a second transmission to the mobile device to implement usage of separate channel demodulation reference signals.
