1. A method of wireless communication performed by a user equipment (UE), comprising:
communicating on an anchor carrier using a first antenna port of the UE;
communicating on a non-anchor carrier using a second antenna port of the UE;
determining to switch the non-anchor carrier from the second antenna port to the first antenna port based on a channel condition associated with the second antenna port and based on one or more of a first power limit associated with the first antenna port or a second power limit associated with the second antenna port, wherein the first power limit associated with the first antenna port is different from the second power limit associated with the second antenna port; and
switching the non-anchor carrier from the second antenna port to the first antenna port based on determining to switch the non-anchor carrier from the second antenna port to the first antenna port.
