Problems solved by technology

The identified one or more frequency bands or frequency band combinations cannot be simultaneously used with the current LTE serving cells due to RE sharing (e.g., will be used for the 2G / 3G voice call) or other limitation of the dual-standby architecture.
The identified one or more frequency bands or frequency band combinations cannot be simultaneously used with the current LTE serving cells due to RF sharing (e.g., will be used for a 2G / 3G voice call) or other limitation of the dual-standby architecture.

Embodiment Construction

[0012]The following description is presented to enable any person skilled in the art to create and use a computer system configuration and related method and article of manufacture to notify an eNodeB of which network a RF chain switchable between at least two disparate networks (e.g., LTE and 3G, LTE and 2G, etc.) will be supporting in connection with a service event (e.g., start of a voice call) are described herein. The switchable RF chain is included in a UE capable of dual-network operation. The dual network architecture supports CA. The UE provides notification to its associated eNodeB when the frequency band to be used for the service event (e.g., 2G / 3G voice call) is the same as or close to the frequency band used for the other network service (e.g., LTE service). In some embodiments RRC signaling is used to provide the information about RF sharing to the eNodeB. In other embodiments Activation / Deactivation MAC CE signaling is triggered by RF sharing information provided by ...

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.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to U.S. Provisional Patent Application No. 61 / 612,188 entitled “Wireless Communication Systems and Methods” filed on Mar. 16, 2012, the content of which is incorporated herein by reference in its entirety.TECHNICAL HELD[0002]The present disclosure relates generally to wireless communications. More particularly, the present disclosure relates to carrier aggregation support in wireless communication systems.BACKGROUND[0003]Dual wireless technology architecture (also referred to as dual-standby architecture) comprises user equipment (UE) using a first wireless technology for voice communications (e.g., phone calls) and a second wireless technology for data communications (e.g., web browsing). As an example, the first wireless technology can be 2nd Generation (2G) or 3rd Generation (3G) cellular technology, and the second wireless technology can be a 3rd Generation Partnership Project (3GPP) long term evolutio...
