Abstract  Abstract

An apparatus and method for using a radio frequency (RF chain) in a dual-network architecture are disclosed herein. An evolved node B (eNodeB) receives RF chain sharing information from user equipment (UE) associated with the eNodeB. The RF chain sharing information comprises indication of a non-usable frequency band or indication of which frequency band is supported for each of a first network and a second network that an RF chain is switchable between. The RF chain is included in the UE and at least a frequency band is shared between the first and second networks. The eNodeB transmits radio resource control (RRC) connection reconfiguration signaling to the UE to release a secondary cell (SCell) or perform inter-frequency handover of a primary cell (PCell) in response to the RF chain sharing information.
