Abstract
A method, apparatus and computer program product are provided in order to enhance network notification of secondary cell activation. In a first embodiment, the method includes receiving a secondary cell activation command, activating a secondary cell, and transmitting a PHR indicating activation of the secondary cell. In a second embodiment, the method includes receiving a secondary cell activation command, activating a secondary cell, and transmitting a signal indicating an expected time period until activation of the secondary cell. In a third embodiment, the method may optimize implicit SCell deactivation by receiving a secondary cell activation command, activating a secondary cell, receiving a PDCCH order for an uplink grant or a downlink assignment, and starting a secondary cell deactivation timer associated with the secondary cell in response to receiving the PDCCH order. A corresponding apparatus and computer program product are also provided.
