Feedback design for multi-transmission reception point transmission

A method for wireless communication at a base station, comprising:

• transmitting a configuration message for configuring a user equipment (UE) to communicate coordinated transmissions with a plurality of transmission reception points using a first coordinated transmission mode of a plurality of different coordinated transmission modes, wherein the configuration message indicates a plurality of control resource set identifiers;
• transmitting downlink control information indicating at least one uplink resource, wherein the downlink control information is transmitted via a first control resource set associated with a first control resource set identifier of the plurality of control resource set identifiers and is transmitted during a physical downlink control channel monitoring occasion of a plurality of physical downlink control monitoring occasions;
• transmitting a second downlink control information in a second control resource set, the second control resource set being associated with a second control resource set identifier of the plurality of control resource set identifiers;
• transmitting a first coordinated transmission in accordance with the first coordinated transmission mode;
• and
• receiving, in response to the first coordinated transmission and in accordance with a feedback configuration corresponding to the first coordinated transmission mode, a feedback message via the at least one uplink resource based at least in part on the downlink control information being a last downlink control information, wherein the downlink control information is the last downlink control information based at least in part on an ordering of the first and second control resource set identifiers.

A user equipment (UE), comprising:

• a transceiver;
• at least one processor;
• and
• memory comprising instructions executable by the at least one processor to cause the UE to:
• receive, via the transceiver, a configuration message configuring the UE to communicate coordinated transmissions with a plurality of transmission reception points using a first coordinated transmission mode of a plurality of different coordinated transmission modes, wherein the configuration message indicates a plurality of control resource set identifiers;
• receive, via the transceiver, downlink control information indicating at least one uplink resource, wherein the downlink control information is received via a first control resource set associated with a first control resource set identifier of the plurality of control resource set identifiers and is received during a physical downlink control channel monitoring occasion of a plurality of physical downlink control monitoring occasions;
• receive, via the transceiver, a second downlink control information in a second control resource set, the second control resource set being associated with a second control resource set identifier of the plurality of control resource set identifiers;
• receive, via the transceiver, a first coordinated transmission in accordance with the first coordinated transmission mode;
• generate a feedback message based at least in part on and the first coordinated transmission mode;
• and
• transmit, via the transceiver in response to the first coordinated transmission, the feedback message via the at least one uplink resource based at least in part on the downlink control information being a last downlink control information, wherein the downlink control information is the last downlink control information based at least in part on an ordering of the first and second control resource set identifiers.
