Abstract

Systems, apparatuses, and methods for uplink timing maintenance in wireless communications are provided. Certain aspects of the disclosure involve applying a timing advance command to adjust uplink transmission timing/resume uplink synchronization; and determining a metric. The metric can be used in determining whether to apply a timing advance command (TAC) to resume uplink resynchronization.
