System and method for SRS switching, transmission, and enhancements

An apparatus comprising:

• a non-transitory memory storage comprising instructions;
• and
• one or more processors in communication with the non-transitory memory storage, wherein the instructions, when executed by the one or more processors, cause the apparatus to perform:
• receiving, from a base station, first configuration information for one or more uplink transmissions of the apparatus on a first component carrier (CC);
• receiving, from the base station, second configuration information for sounding resource signal (SRS) carrier switching, the SRS carrier switching being for transmission of one or more sounding resource signals (SRSs) over a second CC different from the first CC;
• and
• transmitting an SRS over the second CC by performing the SRS carrier switching in accordance with the second configuration information, with uplink transmission over the first CC suspended at least during transmission of the SRS and during a radio frequency (RF) retuning time.

A non-transitory computer-readable media storing computer instructions that, when executed by one or more processors of an apparatus, cause the apparatus to perform:

• receiving, from a base station, first configuration information for one or more uplink transmissions of the apparatus on a first component carrier (CC);
• receiving, from the base station, second configuration information for sounding resource signal (SRS) carrier switching, the SRS carrier switching being for transmission of one or more sounding resource signals (SRSs) over a second CC different from the first CC;
• and
• transmitting an SRS over the second CC by performing the SRS carrier switching in accordance with the second configuration information, with uplink transmission over the first CC suspended at least during transmission of the SRS and during a radio frequency (RF) retuning time.
