Dynamic sounding reference signal antenna switching with transmission carrier switching

A method of wireless communication performed by a user equipment (UE), comprising:

• receiving an indication of a sounding reference signal (SRS) antenna switching (AS) configuration associated with a plurality of SRS AS types associated with different quantities of transmission chains;
• selecting, from the plurality of SRS AS types, an SRS AS type for a first carrier based on a quantity of transmission chains available for the first carrier;
• and
• transmitting, in a transmission interval, one or more uplink signals on one or more of the first carrier or a second carrier according to the selected SRS AS type, wherein the one or more uplink signals include one or more of an SRS or an uplink communication.

A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
• receive an indication of a sounding reference signal (SRS) antenna switching (AS) configuration associated with a plurality of SRS AS types associated with different quantities of transmission chains;
• select, from the plurality of SRS AS types, an SRS AS type for a first carrier based on a quantity of transmission chains available for the first carrier;
• and
• transmit, in a transmission interval, one or more uplink signals on one or more of the first carrier or a second carrier according to the selected SRS AS type, wherein the one or more uplink signals include one or more of an SRS or an uplink communication.
