    • 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.
    • 通过提供切换机制来减轻上行链路传输的可用发射功率或功率余量的不确定性,长期演进(LTE)协议​​增强实现LTE网络中双重连接用户设备(UE)的全部优点,从而有效利用 上行链路无线资源可以实现双连接。 无线电资源控制(RRC)消息的新领域使得能够在交替的时间段期间切换到主要和次要演进的节点B(MeNB和SeNB)的交替传输。 增强型媒体访问控制元件能够由MeNB,SeNB或UE切换。 在一个实施例中,当UE在奇数时间段期间调度到MeNB的上行链路传输时,或者在奇数编号的时间划分期间,当UE调度上行链路传输到 MeNB在偶数时间段内。

    • A 3GPP LTE protocol enhancement may realize the full benefit of dual connectivity in Long Term Evolution (LTE) networks by providing a mechanism to carry Radio Resource Control (RRC) messages and/or Information Elements (IE)s from a Secondary Evolved Node B (SeNB) to User Equipment (UE) via Master Evolved Node B (MeNB) RRC messages. Novel downlink (DL) Common Control Channel (CCCH) and Dedicated Control Channel (DCCH) messages, and augmented messages having Information Elements (IE)s for relaying RRC messages from a SeNB to a UE via a MeNB, are defined. Modifications to ASN.1 program coding of LTE 3rd Generation Partnership Project specifications to enable RRC messages from the MeNB to relay RRC information from the SeNB to the UE are provided. In one embodiment, the UE receives, from a MeNB, an RRC message comprising information relayed from a SeNB and interprets the RRC message for control channel and radio resource configuration information from the SeNB.
