Patent ID: 10362635

Abstract:
An apparatus for communicating with a Long-Term Evolution LTE network comprises a wireless communications module operable in a Frequency Division Duplexing FDD mode and a Time Division Duplexing TDD mode, the apparatus having different capabilities in the FDD and TDD modes. The apparatus sends capability information related to capabilities and/or feature groups supported by the apparatus to the network, the capability information including a legacy part and an extension part such that a legacy LTE node can comprehend the capability information from the legacy part and not from the extension part. The extension part is included in an existing User Equipment Evolved Universal Terrestrial Radio Access UE-EUTRA-Capability Information Element, or is separate to the UE-EUTRA-Capability Information Element. A Radio Access Network RAN node for use in the LTE network is also disclosed, the node being arranged to identify different capabilities and/or feature groups supported by the apparatus in the FDD and TDD modes based on the capability information. Methods for use in the apparatus and node are also provided.
