Abstract: Methods and apparatus, including computer program products, are provided for dual connectivity. In one aspect there is provided a method. The method may include switching, by a user equipment, between a first carrier associated with a first base station and a second carrier associated with a second base station, wherein the switching is performed based on at least a configuration defining when to perform the switching; and indicate an extension of a time allocated by the configuration at the first base station. Related apparatus, systems, methods, and articles are also described.

Abstract: A method, apparatus and computer program product are provided to receive, at a user equipment, an indication providing a cell location to which the user equipment, operating in a dual connectivity mode, should transmit a buffer status report for one or more bearers, the cell location being one of a first location, a second location, or a first location and second location and in response to being triggered, causing buffer status report to be transmitted to the location provided in the indication. In some embodiments, the bearer may be a split bearer. In some embodiments, the indication may be provided by RRC signaling, MAC signaling or physical layer signaling.

Abstract: Methods and apparatus, including computer program products, are provided for reversible handovers. In one aspect there is provided a method. The method may include starting a timeout period in response to an event associated with a handover of a user equipment from a source cell to a target cell; and waiting, until an expiration of the timeout period, to detach from the source cell to enable the user equipment to perform a reverse handover back to the source cell. Related apparatus, systems, methods, and articles are also described.

Abstract: Methods, apparatuses, and computer program products for discontinuous reception (DRX) are provided. One method may include configuring a user equipment with a first inactivity timer and a second inactivity timer. The user equipment may be further configured, after decoding a physical downlink control channel (PDCCH) indicating a new data transmission, to start the first inactivity timer for a first N times of active time, and to start the second inactivity timer for times subsequent to the first N times. If a short DRX cycle is configured, expiry of the first inactivity timer does not start a short discontinuous reception (DRX) cycle, while expiry of the second inactivity timer starts the short discontinuous reception (DRX) cycle.
