1. A method of controlling a media access control (MAC) communication protocol layer in a wireless network, comprising:
- monitoring a characteristic of a data frame to be transmitted on a MAC layer after a basic service set (BSS) for the wireless network starts; and
changing the MAC layer super-frame length, if determined based upon the monitoring that a super-frame length needs to be changed due to a variation in a transmission duration of the data frame.

Abstract
A method and system varying super-frame length information in a wireless network according to characteristics of transmitted data frames and/or a channel status after a basic service set (BSS) is initiated. Characteristics of a data frame to be transmitted on a MAC layer after the BSS initiation is monitored, and if determined as a result of the monitoring that the super-frame length information needs to be changed due to a variation in a transmission duration of the data frame, the super-frame length information is changed.

6. A media access control (MAC) communication protocol layer system in a wireless network, comprising:
-
a protocol controller analyzing a characteristic of a data frame to be transmitted on the wireless network MAC layer after a basic service set (BSS) for the wireless network starts; and
a channel monitor monitoring the analyzed characteristic of the data frame, determining according to the monitoring whether to change the MAC layer super-frame length due to a variation in a transmission duration of the data frame, changing the super-frame length, and informing the protocol controller of the changed super-frame length. - View Dependent Claims (7, 8, 9, 10)
