1. A method for wireless communication by a user equipment (UE), the method comprising:
reporting, to a network node, a first indication of uplink transmission (UL Tx) switching time of the UE for a first communication frequency and an uplink data preparation time, wherein the UL Tx switching time is a time for the UE to switch between transmitting on different frequency bands, and wherein the uplink data preparation time is an amount of time between an end of a downlink reception and a start of an uplink transmission by the UE;
reporting a second indication of UL Tx switching time for a second communication frequency, the second indication of UL Tx switching time being different than the first indication of UL Tx switching time;
receiving an indication of uplink scheduling from the network node for the first communication frequency or the second communication frequency based on the reporting; and
communicating with the network node based on the uplink scheduling.
