Time-domain bundling of sounding reference signals

A method of wireless communication at a base station, the method comprising:

• transmitting to a user equipment a plurality of SRS configurations that are defined to maintain phase continuity across a plurality of sounding reference signal (SRS) transmissions associated with a plurality of SRS occasions;
• receiving from the user equipment a first SRS transmission of the plurality of SRS transmissions during a first SRS occasion of the plurality of SRS occasions;
• receiving from the user equipment a second SRS transmission of the plurality of SRS transmissions during a second SRS occasion of the plurality of SRS occasions;
• and
• jointly processing the first SRS transmission and the second SRS transmission to generate an SRS estimate.

A user equipment, comprising:

• a transceiver;
• a memory;
• and
• a processor coupled to the transceiver and the memory, wherein the processor is configured to:
• receive via the transceiver a first resource allocation for a first sounding reference signal (SRS) transmission scheduled for a first SRS occasion and a first SRS configuration for the first SRS transmission;
• receive via the transceiver a second resource allocation for a second SRS transmission scheduled for a second SRS occasion and a second SRS configuration for the second SRS transmission;
• receive via the transceiver an indication to maintain phase continuity across the first SRS transmission and the second SRS transmission;
• and
• transmit via the transceiver the first SRS transmission during the first SRS occasion and the second SRS transmission during the second SRS occasion after verifying whether use of the first SRS configuration and the second SRS configuration will maintain the phase continuity across the first SRS transmission and the second SRS transmission.

A method for wireless communication at a user equipment, the method comprising:

• receiving a first resource allocation for a first sounding reference signal (SRS) transmission scheduled for a first SRS occasion and a first SRS configuration for the first SRS transmission;
• receiving a second resource allocation for a second SRS transmission scheduled for a second SRS occasion and a second SRS configuration for the second SRS transmission;
• receiving an indication to maintain phase continuity across the first SRS transmission and the second SRS transmission;
• and
• transmitting the first SRS transmission during the first SRS occasion and the second SRS transmission during the second SRS occasion after verifying whether use of the first SRS configuration and the second SRS configuration will maintain the phase continuity across the first SRS transmission and the second SRS transmission.
