Abstract: Systems, methods, apparatuses, and computer program products for an uplink timing synchronization recovery process for RACH-less handover are provided. One method includes detecting, by a network node, that at least one uplink transmission has not been successfully received from a user equipment. The method may also include transmitting a physical downlink control channel (PDCCH) order to the user equipment for re-initiating random access procedure (RACH) in order to become uplink synchronized.

Abstract: A method and apparatus may include receiving a time-alignment value for a time-alignment timer. The method may also include starting the time-alignment timer. The method may also include transmitting one or more uplink transmissions. The uplink transmission is transmitted while the time-alignment timer is running. The method may also include receiving an updated time-alignment while the time-alignment timer is running, if the timing of the uplink transmission is determined to be correct. The method may also include applying the updated time-alignment, if the updated time-alignment is received. The method may also include stopping uplink transmissions, if no updated time alignment is received.

Abstract: Various communication systems may benefit from indications of conditions existing within the system. For example, communication systems employing dual connectivity may benefit from an indication of whether or not a user equipment is in a dual connectivity synchronized condition. A method can include determining a dual connectivity synchronization condition for the user equipment with respect to at least two base stations. The method can also include reporting the dual connectivity synchronization condition to a network element.
