Multiple timing advances for multiple transmission reception points

An apparatus for wireless communication, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• receive a configuration message including a serving cell configuration and a bandwidth part configuration, wherein the serving cell configuration includes first timing advance information for a component carrier, and wherein the bandwidth part configuration includes second timing advance information and third timing advance information for a bandwidth part of the component carrier;
• transmit a first uplink signal to a first transmission reception point (TRP) using the bandwidth part based on a first timing advance value associated with the first timing advance information and a second timing advance value associated with the second timing advance information;
• and
• transmit a second uplink signal to a second TRP using the bandwidth part based on the first timing advance value associated with the first timing advance information and a third timing advance value associated with the third timing advance information.

A method of wireless communication for a user equipment (UE), comprising:

• receiving a configuration message including a serving cell configuration and a bandwidth part configuration, wherein the serving cell configuration includes first timing advance information for a component carrier, and wherein the bandwidth part configuration includes second timing advance information and third timing advance information for a bandwidth part of the component carrier;
• transmitting a first uplink signal to a first transmission reception point (TRP) using the bandwidth part based on a first timing advance value associated with the first timing advance information and a second timing advance value associated with the second timing advance information;
• and
• transmitting a second uplink signal to a second TRP using the bandwidth part based on the first timing advance value associated with the first timing advance information and a third timing advance value associated with the third timing advance information.
