    Abstract: The present invention provides a method and system for optimizing user equipment performance by having faster resumption of services during co-existence of LTE Frequency division duplexing (FDD) and Time division duplexing (TDD) networks. The method includes determining whether the UE is able to acquire essential system information (SI) associated with a cell or frequency which is barred by the UE. Further, the method includes removing the barring restriction conditionally for that cell or frequency which is barred by the UE if the UE is able to acquire the essential system information associated with the cell frequency. Furthermore, the method includes, allowing the UE to camp on the cell or frequency whose essential SI has been acquired by the UE and resuming the service with the cell and frequency. Furthermore, it also includes the method to have seamless handover between TDD and FDD and vice versa.

    Abstract translation: 本发明提供了一种通过在LTE频分双工（FDD）和时分双工（TDD）网络共存期间更快恢复业务来优化用户设备性能的方法和系统。 该方法包括确定UE是否能够获取与由UE禁止的小区或频率相关联的基本系统信息（SI）。 此外，该方法包括：如果UE能够获取与小区频率相关联的基本系统信息，则有条件地移除针对该小区或由UE禁止的频率的限制限制。 此外，该方法包括：允许UE驻留在其基本SI已由UE获取并且以小区和频率恢复服务的小区或频率上。 此外，它还包括在TDD和FDD之间进行无缝切换的方法，反之亦然。

    Abstract: Methods and apparatus are provided for HFN synchronization in a wireless communication system. If re-establishment of an RLC entity occurs during a pending RLC reset procedure, the pending RLC reset procedure is aborted and the re-establishment of the RLC entity is performed. A first RC variable included in a RESET PDU is incremented. The pending RLC reset procedure is restarted. The RESET PDU including the incremented first RC variable is transmitted. A RESET ACKnowledgement (ACK) PDU for the RESET PDU including a second RC variable is received. The second RC variable included in the received RESET ACK PDU is checked and the received RESET ACK PDU is accepted based on the checking result.
