The present invention provides a method for forwarding an uplink packet performed by a node in a wireless communication system, the method being characterized in that the uplink packet including a first cost is received, the first cost is compared with a second cost corresponding to a cost of the node to determine whether to forward the uplink packet, and on the basis of the determination the uplink packet is forwarded, the node forwards the uplink packet when a value of the second cost is smaller than a value of the first cost, and the node does not forward the uplink packet when the second cost value is not smaller than the first cost value.

Methods for reserving a data channel and apparatuses supporting the same are disclosed. A method for reserving a data channel in a wireless access system includes transmitting a request frame for reserving the data channel by a sending node, and receiving a notify frame in response to the request frame during a first time period or a second time period by the sending node. If the notify frame is received during the first time period, the sending node determines that the request frame has been collided, and if the notify frame is received during the second time period, the sending node determines that the data channel has been reserved successfully.
