Abstract
Example methods and apparatus to implement timing advance enhancements for cellular communications are disclosed. A disclosed example method to communicate over a cellular network by a device involves retrieving a stored timing advance value and determining if the stored timing advance value is valid based at least on whether the device is operating in a stationary mode. When the stored timing advance is valid, a contention-based transmission is transmitted to a network using the stored timing advance value in order to compensate for propagation delay.
