RADIO RESOURCE CONTROL MESSAGING FOR DUAL CONNECTIVITY NETWORKS

摘要

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.

1. A User Equipment (UE) comprising a processor and transceiver configured to:
receive, from a Master Evolved Node B (MeNB), a Radio Resource Control (RRC) message comprising control channel and radio resource configuration information relayed from a Secondary Evolved Node B (SeNB); extract the relayed SeNB control channel and radio resource configuration information from the RRC message; and configure the UE for dual connectivity according to the extracted SeNB control channel and radio resource configuration information.
