Abstract
The present invention relates to a method and device for reducing the level of blind decoding complexity when detecting a control channel in a broadband wireless access system supporting multicarrier operation. Examples of the present invention disclose methods for the effective blind decoding of a control channel using an explicit method and implicit methods when sending a control channel based on multicarrier operation as with a control channel for transmitting downlink or uplink allocation information under carrier aggregation conditions.
Claims14
A method for detecting a control channel in a multi-carrier system, the method comprising:
- receiving a first control signal including carrier information allocated to a terminal supporting a plurality of carriers;
- performing blind decoding using the first control signal to detect the control channel;
- and
- receiving a second control signal on the detected control channel,
- wherein the terminal decodes only a specific carrier selected from a candidate carrier set based on the first control signal, without decoding all carriers allocated to the terminal.
A terminal for detecting a control channel in a multi-carrier system, comprising:
- a radio Frequency (RF) module for transmitting and receiving a radio signal;
- and
- a processor for detecting the control channel,
- wherein the processor is adapted to perform:
- receiving a first control signal including carrier information allocated to the terminal supporting a plurality of carriers;
- performing blind decoding using the first control signal to detect the control channel;
- and
- receiving a second control signal on the detected control channel,
- wherein the terminal decodes only a specific carrier selected from a candidate carrier set based on the first control signal, without decoding all carriers allocated to the terminal.
