Uplink signal transmission method via a competition-based uplink channel

摘要

Embodiments of the present invention provide methods for providing competition uplink channels while minimizing the frequency of blind decoding operations of a terminal, and devices of supporting the methods. An uplink signal transmission method via a competition-based uplink (CB UL) channel according to one embodiment of the present invention comprises: receiving the configuration information on the CB UL channel from a base station; receiving resource information from the base station, the resource information containing at last one of the following: information on usage time of the CB UL channel, information on activation and deactivation of the CB UL channel and information on cancellation; and inspecting the validity of the resource information. If the resource information is not valid, the resource information is individually allocated to each subframe; if the resource information is valid, the resource information can be periodically and continuously allocated.
