Multi-transmit receive point mode mixing

A user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• one or more processors coupled to the memory, the one or more processors configured to:
• receive, via a first physical downlink control channel (PDCCH), a first downlink control information (DCI) communication for scheduling a first physical downlink shared channel (PDSCH) associated with a first transmit receive point (TRP);
• receive, via a second PDCCH, a second DCI communication for scheduling a second PDSCH associated with a second TRP,
• wherein the first PDCCH and the second PDCCH are configured for multi-TRP scheduling, and
• wherein the first DCI communication and the second DCI communication each indicate, in a transmission configuration indication (TCI) field, a quantity of TCI states,
• wherein the TCI states indicate, for at least one of the first DCI communication or the second DCI communication, at least one of:
• a first quasi co-located (QCL) relationship associated with the first TRP, and a second QCL relationship associated with the second TRP, or
• a first demodulation reference signal (DMRS) port group associated with a first set of downlink transmission layers that is transmitted by the first TRP, and a second DMRS port group associated with a second set of downlink transmission layers that is transmitted by the second TRP;
• and
• receive downlink communications based at least in part on the first DCI communication and the second DCI communication.

A non-transitory computer-readable medium storing one or more instructions for wireless communication, the one or more instructions comprising:

• one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the one or more processors to:
• receive, via a first physical downlink control channel (PDCCH), a first downlink control information (DCI) communication for scheduling a first physical downlink shared channel (PDSCH) associated with a first transmit receive point (TRP);
• receive, via a second PDCCH, a second DCI communication for scheduling a second PDSCH associated with a second TRP,
• wherein the first PDCCH and the second PDCCH are configured for multi-TRP scheduling, and
• wherein the first DCI communication and the second DCI communication each indicate, in a transmission configuration indication (TCI) field, TCI states,
• wherein the TCI states indicate, for at least one of the first DCI communication or the second DCI communication, at least one of:
• a first quasi co-located (QCL) relationship associated with the first TRP, and a second QCL relationship associated with the second TRP, or
• a first demodulation reference signal (DMRS) port group associated with a first set of downlink transmission layers that is transmitted by the first TRP, and a second DMRS port group associated with a second set of downlink transmission layers that is transmitted by the second TRP;
• and
• receive downlink communications based at least in part on the first DCI communication and the second DCI communication.

An apparatus for wireless communication, comprising:

• means for receiving, via a first physical downlink control channel (PDCCH), a first downlink control information (DCI) communication for scheduling a first physical downlink shared channel (PDSCH) associated with a first transmit receive point (TRP);
• means for receiving, via a second PDCCH, a second DCI communication for scheduling a second PDSCH associated with a second TRP,
• wherein the first PDCCH and the second PDCCH are configured for multi-TRP scheduling, and
• wherein the first DCI communication and the second DCI communication each indicate, in a transmission configuration indication (TCI) field, TCI states,
• wherein the TCI states indicate, for at least one of the first DCI communication or the second DCI communication, at least one of:
• a first quasi co-located (QCL) relationship associated with the first TRP, and a second QCL relationship associated with the second TRP, or
• a first demodulation reference signal (DMRS) port group associated with a first set of downlink transmission layers that is transmitted by the first TRP, and a second DMRS port group associated with a second set of downlink transmission layers that is transmitted by the second TRP;
• and
• means for receiving downlink communications based at least in part on the first DCI communication and the second DCI communication.
