Method and apparatus for TTI (transmission time interval) bundling for small cell enhancements in a wireless communication system

摘要

A method and apparatus are disclosed for TTI bundling for small cell enhancements in a wireless communication system. The method includes a UE (User Equipment) that is served by a first cell controlled by a first eNB (evolved Node B) (805). The method also includes the UE receives a first RRC (Radio Resource Control) message for configuring a TTI bundling (810). The method further includes the UE receives a second RRC message for adding a second cell controlled by a second eNB to the UE, wherein the second cell is configured with a PUSCH (Physical Uplink Shared Channel) (815). In addition, the method includes the UE applies the TTI bundling for uplink transmissions on the first cell and does not apply the TTI bundling for uplink transmissions on the second cell (820).
