Resource pair groups for channel state information in multi-transmit receive point deployments

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

• a memory;
• and
• one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
• identify a plurality of channel state information (CSI) reference signal (RS) resource groups, wherein each CSI RS resource group, of the plurality of CSI RS resource groups, includes one or more CSI RS resources;
• identify, based at least in part on the plurality of CSI RS resource groups, a plurality of hypotheses;
• identify, based at least in part on the plurality of CSI RS resource groups and the plurality of hypotheses, a plurality of hypothesis groups, wherein each hypothesis group, of the plurality of hypothesis groups, includes one or more hypotheses from the plurality of hypotheses;
• and
• report, to one or more transmit receive points (TRPs) in a multi-TRP deployment and for the plurality of hypothesis groups, a corresponding plurality of CSIs, wherein each CSI, of the corresponding plurality of CSIs, corresponds to at least one hypothesis of a respective hypothesis group of the plurality of hypothesis groups.

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:
• identify a plurality of channel state information (CSI) reference signal (RS) resource groups, wherein each CSI RS resource group, of the plurality of CSI RS resource groups, includes one or more CSI RS resources;
• identify, based at least in part on the plurality of CSI RS resource groups, a plurality of hypotheses;
• identify, based at least in part on the plurality of CSI RS resource groups and the plurality of hypotheses, a plurality of hypothesis groups, wherein each hypothesis group, of the plurality of hypothesis groups, includes one or more hypotheses from the plurality of hypotheses;
• and
• report, to one or more transmit receive points (TRPs) in a multi-TRP deployment and for the plurality of hypothesis groups, a corresponding plurality of CSIs, wherein each CSI, of the corresponding plurality of CSIs, corresponds to at least one hypothesis of a respective hypothesis group of the plurality of hypothesis groups.

An apparatus for wireless communication, comprising:

• means for identifying a plurality of channel state information (CSI) reference signal (RS) resource groups, wherein each CSI RS resource group, of the plurality of CSI RS resource groups, includes one or more CSI RS resources;
• means for identifying, based at least in part on the plurality of CSI RS resource groups, a plurality of hypotheses;
• means for identifying, based at least in part on the plurality of CSI RS resource groups and the plurality of hypotheses, a plurality of hypothesis groups, wherein each hypothesis group, of the plurality of hypothesis groups, includes one or more hypotheses from the plurality of hypotheses;
• and
• means for reporting, to one or more transmit receive points (TRPs) in a multi-TRP deployment and for the plurality of hypothesis groups, a corresponding plurality of CSIs, wherein each CSI, of the corresponding plurality of CSIs, corresponds to at least one hypothesis of a respective hypothesis group of the plurality of hypothesis groups.
