1. A method for wireless communication at a user equipment (UE), comprising:
receiving, from a network device, an indication of a duration of a monitoring window used by the network device to monitor for uplink transmissions from the UE, wherein the duration of the monitoring window is associated with a switching time of the UE;
receiving a control signal scheduling uplink resources for an uplink transmission by the UE on at least a first component carrier, the first component carrier in a first radio frequency spectrum band;
reconfiguring, in response to the received control signal, a first transmit chain of the UE from a second component carrier in a second radio frequency spectrum band to the first component carrier in the first radio frequency spectrum band for the uplink transmission; and
transmitting, within the duration of the monitoring window and using at least the reconfigured first transmit chain, the uplink transmission on the first component carrier using the scheduled uplink resources.
