Claim Text:
1. A method for configuring a control channel for radio communication, comprising a step of configuring a control channel by using a plurality of tiles, wherein a number of resource elements in the plurality of tiles are configured to be the same or different, wherein the step of configuring the control channel by using the plurality of tiles includes a step of generating at least one orthogonal sequence to be transmitted through the control channel, and a number of the at least one orthogonal sequence is configured to be the same as a number of tiles constituting the control channel, wherein only the at least one orthogonal sequence is mapped to each of the plurality of tiles, or the at least one orthogonal sequence and reference signals for channel estimation are mapped to each of the plurality of tiles, and wherein a length of the at least one orthogonal sequence is configured to be a value of the number of resource elements included in the each of the plurality of tiles subtracted by a number of reference signals mapped to the each of the plurality of tiles when the at least one orthogonal sequence and reference signals for channel estimation are mapped to the each of the plurality of tiles.
