Choosing an srs resource set when multiple sets are configured

An apparatus for wireless communication, comprising:

• means for receiving, by a user equipment (UE) from a base station, a trigger for aperiodic sounding reference signal (SRS) transmission for a group of one or more component carriers (CCs);
• means for selecting for transmission, by the UE and in response to the trigger, one or more SRS resource sets for each CC of the group of one or more CCs, wherein at least one CC has multiple SRS resource sets configured for the UE;
• and
• means for transmitting, by the UE to the base station, one or more SRS on each CC of the group of one or more CCs based on the selecting.

An apparatus for wireless communication, comprising:

• at least one processor;
• and
• at least one memory coupled to the at least one processor, wherein the at least one processor is configured to
• receive, by a user equipment (UE) from a base station, a trigger for aperiodic sounding reference signal (SRS) transmission for a group of one or more component carriers (CCs);
• select for transmission, by the UE and in response to the trigger, one or more SRS resource sets for each CC of the group of one or more CCs, wherein at least one CC has multiple SRS resource sets configured for the UE;
• and
• transmit, by the UE to the base station, one or more SRS on each CC of the group of one or more CCs based on the selecting.

A non-transitory computer-readable medium having instructions recorded thereon that, when enacted by one or more computer processors, cause the one or more computer processors to:

• receive, by a user equipment (UE) from a base station, a trigger for aperiodic sounding reference signal (SRS) transmission for a group of one or more component carriers (CCs);
• select for transmission, by the UE and in response to the trigger, one or more SRS resource sets for each CC of the group of one or more CCs, wherein at least one CC has multiple SRS resource sets configured for the UE;
• and
• transmit, by the UE to the base station, one or more SRS on each CC of the group of one or more CCs based on the selecting.
