Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a sidelink synchronization signal and may identify a set of parameters (e.g., cyclic shifts or orthogonal cover codes) that are configured for generating a set of reference signals for transmission within a sidelink broadcast resource based on receiving the sidelink synchronization signal. The UE may transmit, within the sidelink broadcast channel resource, a first reference signal of the set of reference signals that is generated based on applying, to a reference signal sequence, a first parameter of the set of parameters that is orthogonal to a second parameter of the set of parameters that is applied to the reference signal sequence to generate a second reference signal of the set of reference signals.
