Abstract: A method of driving gate lines is used to activate the gate lines by outputting output signals of stages to the gate lines. A first node is boosted up based upon a carry signal or the vertical start signal from a previous stage. A gate signal that is pulled up is outputted through an output terminal of a present stage based upon a first clock signal which is boosted up. An off-voltage is outputted through the output terminal of the present stage in response to an output signal from a next stage or the vertical start signal. The first node is discharged in response to the output signal from the next stage or a carry signal from a last stage. A positive ripple voltage at the first node is removed by providing a negative ripple voltage to the first node.

Abstract: A method of channel assessment and channel searching in a wireless network is disclosed. The wireless network separately performs a channel assessment procedure and a channel searching procedure for channel change or another object. The channel assessment procedure is to measure a status or quality of a channel which is currently used in the wireless network. A coordinator of the wireless network designates a time interval for the channel assessment to notify other device of it. The channel assessment procedure may be performed periodically, and is preferably scheduled to allow other devices not to use the channel for the time interval which at least one device performs channel assessment.

Abstract: A method for performing beam tracking in a wireless communication network is provided. In the method, a transmitter station emits beam patterns including respective beam pattern indices to receiver stations and receives a feedback index indicating one of the beam patterns from each receiver station during a predetermined channel time after the emission of beam patterns is completed. A beam pattern feedback is processed using a simple code, thereby minimizing the amount of information and hardware required for beam search and tracking. In addition, in uni-directional beam tracking, it is possible to perform tracking on a number of beam links at once and a sub-channel that can be used for beam tracking and search is allocated to each station to allow a number of stations to simultaneously perform beam search, thereby reducing the amount of used channel time.

Abstract: The present invention relates to a handover method that a current coordinator transfers a coordinating function of controlling a network to a different device configuring the network. The present invention relates to a method of selecting an optimal device as a coordinator in selecting the different device using priority information decided by a prescribed evaluation reference. And, the present invention relates to a method of simplifying a procedure in a manner of transmitting relevant information together with a handover request message. In a wireless network including a coordinator, a secondary coordinator is decided in advance. If the coordinator is suddenly unable to perform a function, the present invention relates to a method of enabling the function of the coordinator to be performed by the decided secondary coordinator. Thus, a process for transferring the coordinating function without the handover process is called a recovery process.
