Techniques for indicating uplink transmission capabilities in wireless communications

A method for wireless communication, comprising:

• receiving, from a user equipment (UE), an indication of a capability to support concurrent or time division multiplexed uplink transmission of at least one of multiple uplink channels across multiple component carriers;
• determining, based on the indication, a configuration for the UE for transmitting over the at least one of the multiple uplink channels over the multiple component carriers using concurrent transmission or time division multiplexed transmission;
• and
• transmitting, based on the indication, the configuration to the UE.

An apparatus for wireless communication, comprising:

• a transceiver;
• a memory configured to store instructions;
• one or more processors communicatively coupled with the memory and the transceiver, wherein the one or more processors are configured to:
• transmit an indication of a capability to support concurrent or time division multiplexed uplink transmission of at least one of multiple uplink channels across multiple component carriers;
• transmit a second indication of at least one of a number of physical antennas or a number of transmission layers of the at least one of the multiple uplink channels supported for each of the multiple component carriers or each of multiple combinations of the multiple component carriers;
• and
• receive, based on the indication and the second indication, a configuration to transmit over the at least one of the multiple uplink channels over the multiple component carriers using concurrent transmission or time division multiplexed transmission.
