Embodiments for providing reference signal generation redundancy in wireless communications systems are disclosed. To avoid a single point of failure in reference signal generation that could cause components relying on the reference signal to not operate properly, the reference signal generation circuits disclosed herein include a plurality of reference signal generation modules. One reference signal generation module is configured as the master reference signal generation module to generate a master reference signal distributed in the wireless communication system. The other reference signal generation modules are configured as slave reference signal generation modules. If a failure is detected in the generation of the master reference signal in the master reference signal generation module, another slave reference signal generation module is reconfigured to be the new master reference signal generation module to generate the master reference signal. In this manner, the reference signal generation circuit does not have a single point of failure.
