1. A method for wireless communication, comprising:
transmitting a capability indication including, for each band combination of multiple band combinations, an indication field indicating a capability to support concurrent or time division multiplexed uplink transmission of an uplink channel across multiple component carriers of the band combination;
transmitting a second indication of at least one of a number of physical antennas or a number of transmission layers of the uplink channel supported for each of the multiple component carriers or each of multiple combinations of the multiple component carriers; and
receiving, based on the capability indication and the second indication, a configuration to transmit over the uplink channel over the multiple component carriers of one of the multiple band combinations using concurrent transmission or time division multiplexed transmission.
