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.

A method of transmitting a reference signal performed by a Relay Station (RS) in a wireless communication system comprises allocating a guard time in the front of a backhaul subframe or the end of the backhaul subframe, the backhaul subframe comprising a plurality of slots, each of the plurality of slots comprising a plurality of Orthogonal Frequency Division Multiplexing (OFDM) symbols, and the guard time being a time interval for switching between an access link and a backhaul link, and transmitting a Demodulation Reference Signal (DMRS) to a Base Station (BS) in an OFDM symbol of the backhaul subframe. The OFDM symbol for the DMRS is not over-lapped with the guard time.

Disclosed is a method for transmitting a sounding reference signal from a terminal to a base station in a radio communication system. More specifically, the method comprises the steps of: receiving downlink control information from a base station; checking a flag bit included in said downlink control information; checking an interpretation bit is included in said downlink control information, when said flag bit indicates an uplink; and transmitting an additional sounding reference signal and/or an uplink common channel based on said interpretation bit.

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.

The present invention provides a method and an apparatus for the transmission of control signal in a radio communication system. The method includes the steps of processing first control information on the basis of a first resource index to create a first control signal, processing second control information on the basis of a second resource index to create a second control signal, and transmitting the first control signal and the second control signal.
摘要:
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.
