    Abstract: Disclosed is a method for controlling an operational state of a medium access control layer in a broadband wireless access communication system. The method includes the steps of performing an uplink access of a contention-based scheme to an access point using resources required to perform the uplink access according to the contention-based scheme when data to be transmitted in an access state is detected, and being allocated resources required to perform an uplink access of a contention-free scheme from the access point in a case of failing in the uplink access of the contention-based scheme; and performing a state transition from the access state into the traffic state in a case of having been allocated the resource required for the contention-free scheme, and performing the uplink access of the contention-free scheme to the access point using the allocated resource in the traffic state.

    Abstract: Apparatus and method for transmitting and detecting subchannel constitution scheme information in a multihop relay Broadband Wireless Access (BWA) communication system. The method includes determining a subchannel constitution scheme for fixing a start zone of BW-RS link according to channel information (e.g., channel condition information, interference, and mobility), transmitting determined subchannel constitution scheme information of the start zone using a FCH preamble, detecting physical channel signals of subchannel constitution schemes from the received FCH preamble, checking preset codes, and detecting the subchannel constitution scheme of the start zone using the detected physical channel signals of the subchannel constitution schemes and the codes. The subchannel constitution scheme of the BS-RS link can be adaptively applied based on the channel information.

    Abstract: An apparatus and method for determining a vertical handoff for a node supporting a WLAN and an IEEE 802.16 communication system are provided. Reception of a handoff request message from the node is monitored, an expected change in the total throughput of the WLAN in the case where the node is connected to the WLAN is calculated and compared with zero, and if the throughput change is equal to or greater than zero, the handoff request of the node is acknowledged and the node is handed off to the WLAN.
