Abstract
A Long Term Evolution (LTE) protocol enhancement realizes the full benefit of dual connectivity User Equipment (UE) in LTE networks by providing a toggling mechanism to alleviate uncertainty in available transmit power, or power headroom, for uplink transmissions so that efficient utilization of the uplink radio resources can be achieved in dual connectivity. A new field for Radio Resource Control (RRC) messages enables toggling for alternating transmissions to Master and Secondary Evolved Node Bs (MeNBs and SeNBs) during alternating time periods. An enhanced Media Access Control Element enables toggling by the MeNB, SeNB or UE. In one embodiment, the UE schedules uplink transmissions to a SeNB during even numbered time divisions when the UE schedules the uplink transmissions to the MeNB during the odd numbered time divisions, or during the odd numbered time divisions when the UE schedules the uplink transmissions to the MeNB during the even numbered time divisions.
