摘要:
A method of allocating a radio resource for a relay station in a wireless communication system is disclosed. The method comprise allocating a relay zone to the relay station in a subframe and transmitting a relay control channel to the relay station by using the relay zone, wherein the subframe comprises a plurality of orthogonal frequency division multiplexing (OFDM) symbols in a time domain and a plurality of subcarriers in a frequency domain, wherein the subframe is divided into a user zone used by a user equipment in a cell and the relay zone used by the relay station, and wherein the relay zone comprises some of the plurality of subcarriers. According to the present invention, a subframe structure provides backward compatibility with a legacy wireless communication system. A relay station can effectively find a radio resource allocated to the relay station, thereby decreasing a decoding time.

The present invention relates to a method for transmitting an uplink or downlink grant in a wireless communication system that supports uplink and downlink multiple input multiple output (MIMO) schemes. The method comprises: determining a downlink control information (DCI) format for an uplink or downlink grant to generate control information: attaching a cyclic redundancy check (CRC) for detecting an error in the created control information; and channel-coding the CRC-attached control information, wherein the control information comprises a bit flag for distinguishing whether the grant is an uplink grant or a downlink grant.

A communication method and apparatus using multiple carriers are provided. A primary carrier is configured, and multi-carrier control information for monitoring a control channel of a secondary carrier is transmitted through the primary carrier. A user equipment monitors a control channel of the secondary carrier on the basis of the multi-carrier control information.

A method of performing hybrid automatic repeat request (HARQ) of a user equipment (UE) in a multiple-carrier system is provided. The UE transmits uplink data on an uplink carrier. The UE receives acknowledgement (ACK)/not-acknowledgement (NACK) for the uplink data on a downlink carrier associated with the uplink carrier. Accordingly, HARQ can be supported in a multiple-carrier system.

摘要:
The method for wireless resource subframe allocation comprises the following steps: allocation of the control channel based on the first RAT (Radio Access Technology) of the first control domain, which includes the OFDM symbol of the first number from the sub-frame containing multiple OFDM symbols and multiple subcarriers in the frequency domain; allocation of the control channel based on the second RAT of the second control domain including the OFDM symbol of the second number which follows said first control domain; and the allocation of a data channel in the data domain which includes the OFDM symbols positioned outside said first control domain and second control domain. This invention provides a sub-frame structure which is compatible with existing wireless communication systems. This method allows the continued use of existing control channel systems or base signal structures. The method is also capable of supporting advanced features.
