<p>PROBLEM TO BE SOLVED: To provide a method and a device for TTI bundling under small cell enhancement in a radio communication system.SOLUTION: A method and a device for TTI bundling under small cell enhancement in a radio communication system is disclosed. The method comprises UE (User Equipment) served by a first cell controlled by a first eNB (evolved Node B). The method also includes a step in which the UE receives a first RRC (Radio Resource Control) message, and sets TTI bundling. The method further includes a step in which the UE receives a second RRC message and adds a second cell controlled by a second eNB to the UE. The second cell is set by a PUSCH (Physical Uplink Shared Channel). In addition to this, the method includes a step in which the UE applies TTI bundling to uplink transmission on the first cell, and does not apply TTI bundling to uplink transmission on the second cell.</p> |
