Aspects in a wireless network are disclosed. A user equipment (UE) may report, to a base station, a capability of the UE to simultaneously transmit sounding reference signal (SRS) resources between component carriers (CCs) in carrier aggregation (CA) across at least one frequency band using a specified arrangement of antenna ports and antennas. The UE may receive, from the base station, a configuration to simultaneously transmit the SRS resources using antenna switching for the CCs across the at least one frequency band and the specified arrangement of antenna ports and antennas. The UE may transmit the SRS resources simultaneously between at least two of the plurality of CCs in the at least one frequency band using the received configuration. Among other benefits, this dynamic allocation of resources enables the UE to perform at a level commensurate with its intrinsic capabilities, increasing network efficiency and speed.
