Method and apparatus for supporting synchronous HARQ transmission

摘要

A method and apparatus for supporting synchronous Hybrid Automatic Repeat reQuest (HARQ) transmission of Uplink are disclosed. When uplink/downlink configurations of multiple CA cellsrrier Aggregation (CA) are different, by configuring the HARQ transmission timing relations of primary cell and secondary cell, it is guaranteed that, with cross-carrier scheduling, the timing relation between a transmission of PUSCH in the Pcell and subsequent retransmission of PUSCH in the Scell is the same as that in Long Term Evolution (LTE) and LTE Advanced (LTE-A).
