Abstract: Methods, systems, and devices for wireless communication are described. A device may transmit first control signaling indicating a capability for switching between carriers of a group of carriers during uplink communications using carrier aggregation. The group of carriers include three or more carriers that are each associated with different radio frequency bands.
