Asynchronous carrier aggregation slot alignment

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

• at least one memory;
• and
• at least one processor communicatively coupled with the at least one memory, the at least one processor configured to cause the UE to:
• receive information identifying an offset between a start of a frame on a first component carrier and a start of a frame on a second component carrier, wherein the first component carrier is one of a primary cell (PCell) or a secondary cell (SCell), and wherein the second component carrier is the other of the PCell or the SCell;
• identify a start of a first slot on the first component carrier and a start of a second slot on the second component carrier that coincide with each other based at least in part on the offset and a quantity of slots per frame in a component carrier, of the PCell and the SCell, with a larger subcarrier spacing, wherein the at least one processor, to identify the start of the second slot on the second component carrier, is configured to cause the UE to identify the start of the second slot on the second component carrier based at least in part on a first value when a subcarrier spacing of the PCell is smaller than or equal to a subcarrier spacing of the SCell, and based at least in part on a second value when the subcarrier spacing of the PCell is greater than the subcarrier spacing of the SCell;
• and
• communicate on the first component carrier and the second component carrier based at least in part on the start of the first slot or the start of the second slot.

A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
• receive information identifying an offset between a start of a frame on a first component carrier and a start of a frame on a second component carrier, the first component carrier being one of a primary cell (PCell) or a secondary cell (SCell), and the second component carrier being the other of the PCell or the SCell;
• identify a start of a first slot on the first component carrier and a start of a second slot on the second component carrier that coincide with each other based at least in part on the offset and a quantity of slots per frame in a component carrier, of the PCell and the SCell, with a larger subcarrier spacing, wherein the start of the second slot on the second component carrier is identified based at least in part on a first value when a subcarrier spacing of the PCell is smaller than or equal to a subcarrier spacing of the SCell, and based at least in part on a second value when the subcarrier spacing of the PCell is greater than the subcarrier spacing of the SCell;
• and
• communicate on the first component carrier and the second component carrier based at least in part on the start of the first slot or the start of the second slot.

An apparatus for wireless communication, comprising:

• means for receiving information identifying an offset between a start of a frame on a first component carrier and a start of a frame on a second component carrier, wherein the first component carrier is one of a primary cell (PCell) or a secondary cell (SCell), and wherein the second component carrier is the other of the PCell or the SCell;
• means for identifying a start of a first slot on the first component carrier and a start of a second slot on the second component carrier that coincide with each other based at least in part on the offset and a quantity of slots per frame in a component carrier, of the PCell and the SCell, with a larger subcarrier spacing, wherein the start of the second slot on the second component carrier, is identified based at least in part on a first value when a subcarrier spacing of the PCell is smaller than or equal to a subcarrier spacing of the SCell, and based at least in part on a second value when the subcarrier spacing of the PCell is greater than the subcarrier spacing of the SCell;
• and
• means for communicating on the first component carrier and the second component carrier based at least in part on the start of the first slot or the start of the second slot.
