Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network node may apply an orthogonal time frequency space (OTFS) precoding to a plurality of tracking reference signal (TRS) resource samples allocated in a delay-Doppler domain to obtain a plurality of TRS symbols with the OTFS precoding. The first network node may transmit, to a second network node, a TRS in which the plurality of TRS symbols with the OTFS precoding have a uniform spacing in a time domain. Numerous other aspects are described.
