METHOD AND SYSTEM FOR HANDLING UE BEHAVIOR IN INTER-BAND CARRIER AGGREGATION WITH CELL SPECIFIC TDD CONFIGURATION

摘要

A method and system to handle behavior of a carrier aggregation capable User Equipment (UE) that does not support simultaneous reception and transmission in overlapped Downlink (DL)-Uplink (UL) sub frames during inter-band Carrier Aggregation (CA) for cell specific TDD configuration is disclosed. The method specifies whether the UE is allowed or not allowed to monitor the PDCCH sub frames during overlap of DL-UL sub frames by signaling the UE with a resultant TDD configuration that is applicable to component carriers of the PCell and one or more SCells. The method also addresses handling of the DRX timers by defining the active time for common DRX operation by the UE for all component carriers. The method enhances the 3GPP specification to enable UE to better handle reception and transmission during overlap of DL-UL sub frames in cell specific TDD configuration during inter-band CA.
