Measurement Gap Configuration in Dual Connectivity Enhancement

Abstract

In embodiments, a UE may measure system frame number (SFN)/subframe timing differences between a master eNB (MeNB) and secondary eNB (SeNB) for dual connectivity (DC). When network-based reporting on the SFN/subframe timing offset is used, no new radio access network (RAN) signaling may be needed. However, in the case of multi-vendor deployments, no network coordination via different Operations, Administration, and Maintenance (OAM) for DC may occur. In this case, the network may not be able to obtain SFN/subframe timing offset information. To address this issue, various embodiments disclosed herein include UE-based reporting on SFN/subframe offset between an MeNB and an SeNB.

What is claimed is: 
     
         1 . A user equipment, UE, apparatus, comprising:
 receive logic at least partially implemented in hardware to:
 receive, from a master eNodeB, MeNB, master cell group, MCG, measurement gap information, and 
 receive, from a secondary eNodeB, SeNB, secondary cell group, SCG, measurement gap information; 
   control logic at least partially implemented in hardware to compare the MCG measurement gap information and the SCG measurement gap information; and   transmit logic to transmit, to the MeNB, a result of the comparison.
