Sounding reference signal coordination for periodic traffic

A method for wireless communications at a user equipment (UE), comprising:

• receiving, from a base station, a downlink control information message scheduling periodic downlink bursts of multimedia data traffic;
• receiving, from the base station, first control signaling that indicates that the UE is to transmit a sounding reference signal at a time that is associated with a beginning of at least one of the periodic downlink bursts of multimedia data traffic;
• and
• transmitting, to the base station, the sounding reference signal based at least in part on the first control signaling.

A user equipment (UE) for wireless communications, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the UE to:
• receive, from a base station, a downlink control information message scheduling periodic downlink bursts of multimedia data traffic, the periodic downlink bursts of multimedia data traffic having a first periodic cadence;
• receive, from the base station, control signaling that indicates that the UE is to periodically transmit sounding reference signals to the base station in accordance with a second periodic cadence, wherein the second periodic cadence is a multiple of the first periodic cadence;
• and
• transmit the sounding reference signals to the base station in accordance with the second periodic cadence.
