Dynamic timing advance adjustment schemes

Abstract:

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability or mobility mode indication to a base station. The base station may select a timing advance (TA) adjustment scheme based on the information included in the indication. The base station may select a TA adjustment scheme in which the UE autonomously adjusts a TA value; the UE adjusts the TA value after receiving a command from the base station; or the UE transmits a message to the base station including a proposed TA adjustment, and the UE adjusts the TA value after receiving an approval message from the base station. The base station may transmit a TA adjustment scheme configuration to the UE including an indication of the selected TA adjustment scheme. The UE may adjust a TA value for an uplink transmission based on applying the TA adjustment scheme.
