Cell-group slot format indication (SFI)

A base station comprising:

• a processing system that includes at least one processor and a memory coupled with the at least one processor, the processing system configured to cause the base station to:
• transmit, to a user equipment (UE), configuration information regarding one or more cell-groups supporting full duplex communication, an order of cells in each cell-group of the one or more cell groups, and a cells slot format combination table for all cells in a cell-group of the one or more cell-groups, wherein each cell-group of the one or more cell-groups includes a plurality of cells for which a same cell-group slot format indication (SFI) applies, and wherein the cells slot format combination table includes a plurality of blocks that each include respective cells slot format combination information for a slot format sequence for the plurality of cells in a cell-group of the one or more cell-groups for a plurality of time slots;
• and
• transmit, to the UE, a cell-group SFI (i) that is applicable to the plurality of cells in a selected cell-group of the one or more cell-groups and (ii) that indicates a selected block of the cells slot format combination table for a selected cells slot format combination for the plurality of cells in the selected cell-group, wherein the cells slot format combination provides a different slot format sequence over a plurality of time slots for cells of the plurality of cells in the selected cell-group of the one or more cell-groups.

A method of wireless communication performed by a user equipment (UE), the method comprising:

• receiving, from one or more base stations, configuration information regarding one or more cell-groups supporting full duplex communication, an order of cells in each cell-group of the one or more cell groups, and a cells slot format combination table for all cells in a cell-group of the one or more cell-groups, wherein each cell-group of the one or more cell-groups includes a plurality of cells for which a same cell-group slot format indication (SFI) applies, and wherein the cells slot format combination table includes a plurality of blocks that each include respective cells slot format combination information for a slot format sequence for the plurality of cells in a cell-group of the one or more cell-groups for a plurality of time slots;
• and
• receiving, from a base station of the one or more base stations, a cell-group SFI (i) that is applicable to the plurality of cells in a selected cell-group of the one or more cell-groups and (ii) that indicates a selected block of the cells slot format combination table for a selected cells slot format combination for the plurality of cells in the selected cell-group, wherein the cells slot format combination provides a different slot format sequence over a plurality of time slots for cells of the plurality of cells in the selected cell-group of the one or more cell-groups.

A user equipment (UE) comprising:

• a processing system that includes at least one processor and a memory coupled with the at least one processor, the processing system configured to cause the UE to:
