1. A method for a user equipment (UE) configured to transmit uplink (UL) data in a wireless network based on carrier aggregation (CA), the method comprising:
determining active UL bandwidth parts (BWPs) associated with at least two component carriers (CCs) within a frequency band;
determining at least one UL transmit direct current (TX DC) location for the active UL BWPs;
receiving from the wireless network a request for UL TX DC locations for the UE's active UL BWPs, wherein the request indicates one or more particular requested UL TX DC locations; and
selectively sending, to the wireless network, an indication of the determined at least one UL TX DC location, wherein in response to the request, the indication only indicates the determined at least one UL TX DC location that correspond to the one or more particular requested UL TX DC locations.
