Methods and apparatus for upgrading communication quality

A method of wireless communication at a first User Equipment (UE), comprising:

• determining the first UE is operating using a first radio access technology (RAT) supporting a higher communication quality than a second RAT;
• initiating a communication comprising video media between the first UE and a second UE operating using the second RAT including a communication quality based on the second RAT;
• receiving a second indication from the second UE, wherein the second indication indicates the second UE is in coverage of the first RAT, wherein the second indication indicates the second UE is operating using the first RAT;
• transmitting a session initiation protocol (SIP) update to the second UE, wherein the SIP update indicates a video rate based on the first RAT, wherein the communication following the SIP update is based on the video rate indicated in the SIP update;
• and
• adjusting the communication quality of the communication to the higher communication quality of the first RAT when the second UE is operating using the first RAT.

An apparatus for wireless communication at a first User Equipment (UE), comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• determine the first UE is operating using a first radio access technology (RAT);
• initiate a communication comprising video media between the first UE and a second UE, wherein a communication quality of the communication is based on the first RAT, wherein the second UE is operating using a second RAT supporting a higher communication quality than the first RAT;
• determine that the first UE is in coverage of the second RAT;
• transmit, to the second UE, a second indication indicating that the first UE is in the coverage of the second RAT, wherein the second indication indicates the first UE is operating using the second RAT;
• receive a session initiation protocol (SIP) update from the second UE, wherein the SIP update indicates a video rate based on the second RAT;
• accept the SIP update from the second UE, wherein the communication following acceptance of the SIP update is based on the video rate indicated in the SIP update;
• and
• adjust the communication quality of the communication to the higher communication quality for the second RAT.
