Uplink control channel group and cross-carrier scheduling for user equipment cooperation

A method of wireless communication performed by a base station, the method comprising:

• receiving, by the base station from a served user equipment (UE), a cooperative configuration with one or more member UEs of a virtual UE;
• receiving, by the base station from the served UE, a capability message including associations between a plurality of component carriers (CCs) allocated to a cell group and member UEs of the virtual UE, the associations include one or more supported frequency band combination identifications for member UEs of the virtual UE;
• transmitting, by the base station, an uplink control transmission configuration message dividing the member UEs of the virtual UE into an assigned uplink control transmission group of a plurality of uplink control transmission groups and assigning, in response to the associations, one or more component CCs of the plurality of CCs into one or more CC sets, wherein a CC set of the one or more CC sets is assigned to an uplink control transmission group of the plurality of uplink control transmission groups;
• and
• transmitting, by the base station, an uplink scheduling message to the served UE, wherein the uplink scheduling message includes an uplink schedule for CCs within the CC set assigned to the uplink control transmission group associated with the served UE.

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

• at least one processor;
• and
• a memory coupled to the at least one processor,
• wherein the at least one processor:
• reports, by the UE to a serving base station, a cooperative configuration with one or more member UEs of a virtual UE;
• reports, by the UE to the serving base station, associations between a plurality of component carriers (CCs) allocated to a cell group and member UEs of the virtual UE, the reporting includes transmitting a capability message including the associations, wherein the associations include one or more supported frequency band combination identifications for the member UEs of the virtual UE;
• receives, by the UE, an uplink control transmission configuration message dividing the member UEs of the virtual UE into an assigned uplink control transmission group of a plurality of uplink control transmission groups and assigning one or more component CCs of the plurality of CCs into one or more CC sets, wherein a CC set of the one or more CC sets is assigned to an uplink control transmission group of the plurality of uplink control transmission groups;
• and
• receives, by the UE, an uplink scheduling message from the serving base station, wherein the uplink scheduling message includes an uplink schedule for CCs within the CC set assigned to the uplink control transmission group associated with the UE.
