Abstract: A 3GPP LTE protocol enhancement realizes the full benefit of discontinuous reception (DRX) in Long Term Evolution networks by coordinating and aligning DRX operations for conserving power and timing overhead. A dual connectivity enabled User Equipment (UE) comprising a processor and transceiver is configured to align DRX configuration between counterpart Evolved Node Bs (eNB)s, wherein counterpart eNBs are a Master eNB (MeNB) and a Secondary eNB (SeNB) simultaneously connected to the UE, communicate system frame timing and system frame number (SFN) information between the counterpart eNBs, align DRX start offset (drxStartOffset) values for the counterpart eNBs according to the communicated system frame timing and SFN information to compensate for offsets in system frame timing, and allow the start of a DRX ON duration at specific frame or sub-frame times determined by the drxStartOffset values, after the expiration of a DRX inactivity timer.

Abstract: Embodiments described herein relate generally to a communication between a user equipment (“UE”) and a plurality of evolved Node Bs (“eNBs”). A UE may be adapted to operate in a dual connected mode on respective wireless cells provided by first and second eNBs. The UE may be adapted to estimate respective power headroom (“PHR”) values associated with simultaneous operation on the first and second wireless cells. The UE may cause the first and second PHR estimates to be transmitted to both the first and second eNBs. The first and second eNBs may use these estimates to compute respective uplink transmission powers for the UE. Other embodiments may be described and/or claimed.
