Shared demodulation reference signal for physical downlink control channel and physical downlink shared channel transmissions

A network entity for wireless communication, comprising:

• at least one memory;
• and
• at least one processor coupled to the at least one memory, wherein the network entity is configured to:
• receive a configured shared demodulation reference signal (DMRS);
• determine, based on the configured shared DMRS, blind channel estimation information;
• receive, based on the blind channel estimation information, control information indicative of a scheduled downlink data transmission, wherein the control information includes downlink control information (DCI) indicative of a downlink (DL) grant corresponding to the scheduled downlink data transmission;
• determine one or more resources associated with the configured shared DMRS are included in a plurality of PDSCH resources of the DL grant;
• and
• receive the scheduled downlink data transmission based on the control information and reuse of the blind channel estimation information corresponding to the configured shared DMRS.
