METHOD AND APPARATUS FOR TRANSMITTING CONTROL INFORMATION IN WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a wireless communication system. Specifically, the present invention provides a method for receiving control information by a terminal and an apparatus therefor, the method comprising the steps of: receiving an upper layer signal having first UL-DL configuration information for a TDD cell; receiving a lower layer signal having second UL-DL configuration information for the TDD cell; receiving a DL signal in subframe i of the TDD cell according to the second UL-DL configuration information; and detecting the control information on the basis of the number of PHICH groups in the subframe i.
