METHOD AND APPARATUS FOR APPLYING PUSCH/PHICH SCHEDULING TIMING IN INTER-BAND TDD TRANSMISSION SCHEMES

摘要

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.

1. A method of applying a PUSCH/PHICH (Physical Uplink Shared Channel/Physical Hybrid Automatic Repeat Request Indicator Channel) scheduling timing of a base station that controls two or more bands having different Time Division Duplex (TDD) configurations, based on an inter-band TDD transmission scheme, the method comprising:
transmitting an uplink grant or a PHICH to a user equipment that supports cross-carrier scheduling using two or more serving cells; and receiving a PUSCH from the user equipment, based on at least one PUSCH/PHICH scheduling timing of the two or more serving cells, wherein a PUSCH/PHICH scheduling timing of a scheduling cell of the two or more serving cells is based on a PUSCH/PHICH scheduling timing that is based on a TDD configuration of the scheduling cell, and a PUSCH/PHICH scheduling timing of a scheduled cell is based on a predetermined PUSCH/PHICH scheduling timing.
