Abstract:
1. A method of transmitting an uplink signal at a communication apparatus in a wireless communication system, the method comprising: receiving pattern information of downlink subframes for a base station (BS)-to-the communication apparatus transmission as a bitmap; receiving resource block (RB) information associated with a control channel for the BS-to-the communication apparatus transmission; receiving the control channel from a fourth orthogonal frequency division multiplexing (OFDM) symbol of the downlink subframe n corresponding to a downlink subframe index n based on the RB information and the pattern information, the downlink subframe n comprising at least one downlink subframe other than downlink subframe 0, downlink subframe 4, downlink subframe 5 and downlink subframe 9; receiving a data channel in the downlink subframe n; and transmitting feedback information associated with the data channel to the BS via an uplink subframe for the communication apparatus-to-the BS transmission.
