Abstract:
A user equipment (UE) is described. The UE determines a duplex method of each serving cell for frequency-division duplexing (FDD) and time-division duplexing (TDD) carrier aggregation. At least one serving cell is a TDD cell and at least one serving cell is a FDD cell. The UE also determines a subframe offset. The UE further determines physical downlink shared channel (PDSCH) Hybrid Automatic Repeat Request Acknowledgement/Negative Acknowledgement (HARQ-ACK/NACK) transmission timing for a serving cell. When a primary cell is a TDD cell, the PDSCH HARQ-ACK/NACK transmission timing for the serving cell is determined based on a downlink (DL) association set with the subframe offset for the serving cell. The UE additionally sends PDSCH HARQ-ACK/NACK information based on the PDSCH HARQ-ACK/NACK transmission timing.
