Dynamic timing advance adjustment schemes

A method for wireless communications at a base station, comprising:

• receiving, from a user equipment (UE), a first message comprising information associated with a timing advance adjustment procedure at the UE, wherein the information comprises at least one of a UE capability or mobility mode of the UE;
• selecting a timing advance adjustment scheme from a plurality of timing advance adjustment schemes, wherein the timing advance adjustment scheme is selected based at least in part on the first message;
• transmitting a second message configuring the UE with the selected timing advance adjustment scheme;
• and
• receiving an uplink message from the UE in accordance with the selected timing advance adjustment scheme.

An apparatus for wireless communications at a user equipment (UE), comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• transmit a first message comprising information associated with a timing advance adjustment procedure at the UE, wherein the information comprises at least one of a UE capability or mobility mode of the UE;
• receive a second message configuring the UE with a timing advance adjustment scheme that is from a plurality of timing advance adjustment schemes, the timing advance adjustment scheme being based at least in part on the first message;
• and
• transmit an uplink message based at least in part on performing the timing advance adjustment procedure, wherein the timing advance adjustment procedure comprises applying a timing advance adjustment value to the uplink message in accordance with the timing advance adjustment scheme.
