Abstract: Systems and methods for determining timing advance (TA) validity are disclosed. In some embodiments, systems and methods are disclosed herein in which a wireless device implicitly considers a TA to be valid in a full cell when no TA validation mechanisms are explicitly configured. In other embodiments, systems and methods are disclosed herein in which a timer serves a dual purpose. If the timer is set to infinity, a wireless device will always consider a TA to be valid within a given cell, and at the same time will disable other TA validation mechanisms. Otherwise, the wireless device will interpret the timer as indicating for how long the TA value that the wireless device possesses is considered to be valid. Benefits of the solutions described herein include reducing signaling bits in the configuration and avoiding the possibility of conflicting configurations.
