Claim 13:
14. A wireless device configured to communicate with a network node, the wireless device comprising processing circuitry, the processing circuitry configured to cause the wireless device to:
receive an indication from a network node, the indication indicating whether at least one resource element, RE, associated with a reference signal is one of available and not available for physical downlink shared channel, PDSCH-to-RE mapping, the at least one RE associated with the reference signal being at least one RE in a same orthogonal frequency division multiplex, OFDM, symbol as the reference signal;
receive a PDSCH based on the indication, the PDSCH being one of mapped and not mapped to the at least one RE associated with the reference signal based on the indication, the reference signal being an NZP CSI-RS used as a tracking reference signal;
if the PDSCH demodulation reference signal, DMRS, is quasi collocated, QCL, Type D with the reference signal, the at least one RE associated with the reference signal is available for the PDSCH-to-RE mapping; and
if the PDSCH DMRS is not QCL Type D with the reference signal, the at least one RE associated with the reference signal is not available for the PDSCH-to-RE mapping.
