摘要： In some implementations, a method in a user equipment (UE) for supporting time division duplex (TDD) and frequency division duplex (FDD) joint carrier aggregation (CA) includes receiving a Physical Uplink Control Channel (PUCCH) resource allocation from an evolved NodeB (eNB). The PUCCH resource allocation includes a first PUCCH configuration for a first subframe and a second PUCCH configuration for a second subframe, and the second PUCCH configuration is different than the first PUCCH configuration. The UE transmits a first group of Hybrid Automatic Repeat reQuest (HARQ) bits based on the first PUCCH configuration in the first subframe. The UE transmits a second group of HARQ bits based on the second PUCCH configuration in the second subframe.
