Handling for interruption due to carrier switching and carrier switching capability indication

A method for wireless communications by a base station (BS), comprising:

• sending a query to a user equipment (UE) for capability information of the UE;
• and
• in response to the query, receiving an indication of switching capability information of the UE for one or more carrier aggregation (CA) configurations, the switching capability information associated with switching between a first component carrier (CC) for transmission of a first uplink signal and a second CC for transmission of a second uplink signal, wherein the switching capability information comprises at least one of:
• CCs supported by the UE, CCs between which the UE supports switching, or a switching time associated with switching between different CCs.

An apparatus for wireless communications by a user equipment (UE), comprising:

• means for receiving a query from a base station (BS) for capability information of the UE;
• and
• means for, in response to the query, providing an indication to the BS of the switching capability information of the UE for one or more carrier aggregation (CA) configurations, the switching capability information associated with switching between a first component carrier (CC) for transmission of a first uplink signal and a second CC for transmission of a second uplink signal, wherein the switching capability information comprises at least one of:
• CCs supported by the UE, CCs between which the UE supports switching, or a switching time associated with switching between different CCs.

An apparatus for wireless communications, comprising:

• at least one processor coupled with a memory and configured to:
• interrupt an uplink transmission on a first component carrier (CC) to switch between the first CC and a second CC to transmit an uplink reference signal on the second CC;
• and
• adjust one or more parameters or parameter values of the uplink transmission on the first CC to account for the interrupting communication on the second CC.
