A method for detecting a beacon signal using an above-ground tracker. The tracker comprises an antenna assembly comprising a plurality of antennas. Each antenna is oriented in a different direction. During operation, if the beacon signal is interrupted due to a local noise source, transmission of the beacon signal is stopped. The tracker then detects radiation from the local noise source and the processor determines a direction from which peak ambient noise arrives at the tracker. The beacon signal is then resumed. A processor included in the tracker excludes any signals generated by the antenna assembly that are representative of radiation that arrived at the tracker from the same direction the peak ambient noise arrived at the tracker. The tracker then detects the beacon signal using the non-excluded signals.

Methods, systems, and devices for wireless communications are described. A transmitting (Tx) device transmits, to a receiving (Rx) device, a control message indicating a location of one or more noise spurs associated with wireless communications performed by the Tx device using a set of resources, where the location includes a frequency location of the one or more noise spurs in the frequency domain. The Tx device then generates a data message to be communicated using the set of resources associated with the one or more noise spurs based on transmitting the control message, and transmits the generated data message to the Rx device using the set of resources associated with the one or more noise spurs. By indicating the location of the noise spurs, the Rx device may be more able to more efficiently identify and address (e.g., filter out, ignore) the noise spurs within the data message.
