Multiplexing of uplink control information for operation with multiple transmission-reception points

A user equipment (UE) device, comprising:

• a radio;
• and
• a processor operably coupled to the radio and configured to cause the UE device to perform operations including:
• receiving configuration information comprising a first value of a pool index for a first control resource set (CORESET), wherein the pool index is configured to be one of a 1 or a 0, wherein respective values of the pool index have respective one to one associations with respective transmission and reception points (TRPs);
• receiving a first Physical Downlink Control Channel (PDCCH) transmission on the first CORESET scheduling a first Physical Downlink Shared Channel (PDSCH) transmission from a first TRP;
• transmitting, in response to the first PDSCH transmission, a first aperiodic report of control information in a first Physical Uplink Control Channel (PUCCH) transmission, wherein the first PUCCH transmission is associated with the first value of the pool index corresponding to the first CORESET carrying the first PDCCH transmission scheduling the first PDSCH;
• and
• transmitting, in response to a second PDSCH transmission, a second aperiodic report of control information in a second PUCCH transmission, wherein the second PUCCH transmission is associated with a second value of the pool index corresponding to a second CORESET carrying a second PDCCH transmission scheduling the second PDSCH, wherein the pool index is not configured for the second CORESET.

A method for operating a cellular network, the method comprising:

• transmitting, to a user equipment (UE) device, configuration information comprising a first value of a pool index for a first control resource set (CORESET), wherein the pool index is configured to be one of a 1 or a 0, wherein respective values of the pool index have respective one to one associations with respective transmission and reception points (TRPs);
• transmitting, to the UE device, a first Physical Downlink Control Channel (PDCCH) transmission on the first CORESET scheduling a first Physical Downlink Shared Channel (PDSCH) transmission from a first TRP;
• receiving, from the UE device, in response to the first PDSCH transmission, a first aperiodic report of control information in a first Physical Uplink Control Channel (PUCCH) transmission, wherein the first PUCCH transmission is associated with the first value of the pool index corresponding to the first CORESET carrying the first PDCCH transmission scheduling the first PDSCH;
• and
• receiving, from the UE device, in response to a second PDSCH transmission, a second aperiodic report of control information in a second PUCCH transmission, wherein the second PUCCH transmission is associated with a second value of the pool index corresponding to a second CORESET carrying a second PDCCH transmission scheduling the second PDSCH, wherein the pool index is not configured for the second CORESET.
