Beam management in multi-TRP operation

A cell, comprising:

• a communication interface configured to communicate with a user equipment (UE);
• and
• a processor communicatively coupled to the communication interface and configured to perform operations, the operations comprising:
• transmitting a first group of multiple reference signals via a first transmission reception point (TRP) to the UE;
• transmitting a second group of multiple reference signals via a second different TRP to the UE, wherein the first group of multiple reference signals include radio link monitoring reference signals configured with a CORESETPoolIndex or a physical cell ID (PCI) to be used by the UE for beam failure detection of the first TRP, and the second group of multiple reference signals include radio link monitoring reference signals configured with a different CORESETPoolIndex or a different physical cell ID (PCI) to be used by the UE for beam failure detection of the second TRP;
• receiving an indication that the UE has selected a first beam associated with one of the multiple reference signals of the first group and a second beam associated with one of the multiple reference signals of the second group;
• and
• transmitting downlink data to the UE using the first beam and the second beam.

A method, comprising;

• at a cell of a network;
• transmitting a first group of multiple reference signals via a first transmission reception point (TRP) to a user equipment (UE);
• transmitting a second group of multiple reference signals via a second different TRP to the UE, wherein the first group of multiple reference signals include radio link monitoring reference signals configured with a CORESETPoolIndex or a physical cell ID (PCI) to be used by the UE for beam failure detection of the first TRP, and the second group of multiple reference signals include radio link monitoring reference signals configured with a different CORESETPoolIndex or a different physical cell ID (PCI) to be used by the UE for beam failure detection of the second TRP;
• receiving an indication that the UE has selected a first beam associated with one of the multiple reference signals of the first group and a second beam associated with one of the multiple reference signals of the second group;
• and
• transmitting downlink data to the UE using the first beam and the second beam.
