Abstract: A method and an apparatus for receiving a downlink frame in a wireless LAN are disclosed. The method and apparatus for receiving a downlink frame in a wireless LAN may comprises the steps of: an STA receiving from an AP a downlink frame via a downlink dedicated channel; and the STA transmitting to the AP a response frame related to the downlink frame via the downlink dedicated channel. The downlink dedicated channel allows transmission only of a contention-free downlink frame by the AP and a response frame by the STA, and restricts transmission of an independent uplink frame by the STA, wherein the independent uplink frame may be an uplink frame other than a response frame among uplink frames that are transmitted from the STA to the AP.

Abstract: A method and a mobile station operating in a wireless communication system are described. Information on a primary carrier and one or more secondary carriers is received on a multi-carrier from a base station. Information on activation or deactivation of the one or more secondary carriers is received. The mobile station communicates with the base station via the primary carrier and one or more activated secondary carriers. Configuration information for power management is received that informs the mobile station of a first time period during which the mobile station monitors signals from the base station and of a second time period during which the mobile station does not monitor signals from the base station. When a specific indication is received from the base station, the mobile station stops the first time period and enters into the second time period.
