Abstract
The present invention relates to a method and apparatus for applying PUSCH/PHICH scheduling timing in inter-band TDD transmission schemes. According to an embodiment of the present invention, the method for applying PUSCH/PHICH scheduling timing in inter-band TDD transmission schemes by a base station for controlling two or more different TDD bands includes the steps of: selecting a reference Physical Uplink Shared Channel (PUSCH)/Physical Hybrid ARQ Indicator Channel (PHICH) scheduling the timing of a UE, which supports cross-carrier scheduling by using two or more serving cells; transmitting instruction information for instructing the selected reference PUSCH/PHICH scheduling timing to the UE; and allocating an uplink and/or transmitting a PHICH to the UE according to the reference PUSCH/PHICH scheduling timing.
