The present invention relates to a method, device and system for solving channel collision, which are applied to a Long Term Evaluation Advanced (LTE-A) system. The method includes: receiving control information transmitted by a base station; transmitting uplink data to the base station according to the control information; and receiving decoding results on the uplink data from the base station, and determining the resource location of a Physical Hybrid ARQ Indicator Channel (PHICH) according to the control information, thereby determining the decoding result corresponding to a User Equipment (UE) itself. The implementation of the embodiments of the present invention can avoid the problem of collision the channel resources of the PHICH determined by the UE when the LTE-A has to be compatible with the LTE.
