A magnetodielectric substrate includes a first dielectric layer, a second dielectric layer, conductive patterns, and a plurality of air vias. The first dielectric layer has a predetermined height, and the second dielectric layer is stacked on the first dielectric layer. Conductive patterns are coated on an upper surface and a lower surface of one of the first and second dielectric layers. A plurality of air vias is formed with a predetermined diameter and a predetermined interval such that they pass through up to the conductive patterns of the upper and lower surfaces from the dielectric layer on which the conductive patterns are coated.

An apparatus and method in a broadband wireless communication system are provided. The apparatus includes a Base Station (BS) which includes a manager for increasing a set point associated with a Mobile Station (MS) if an error is detected in a burst received from the MS, a detector for incrementing a counter associated with the MS if a difference, between a maximum Transmission (Tx) power of the MS and a Tx power used by the MS when transmitting the burst in which the error was detected, is less than a difference threshold, and a determining unit for providing control such that a number of slots allocated to the MS decreases if the counter associated with the MS is greater than a counter threshold.

Apparatus and method for determining an uplink transmission format in a broadband wireless communication system

Apparatus and method for guaranteeing a Quality of Service (QoS) traffic rate in a mobile communication system are provided. The scheduling method for guaranteeing a QOS traffic rate in a mobile communication system includes calculating a total sum of traffic rates based on a channel change and a total sum of sustained traffic rates; calculating a weighted traffic rate using the traffic rate based on the channel change and the sustained traffic rate when the sustained traffic rate does not meet the QoS traffic rate; and determining a service priority using the weighted traffic rate. Therefore, the minimum reserved traffic rate and the maximum sustained traffic rate can be assured.

An uplink scheduling system and method in a wireless broadband internet communication system includes calculating priorities of mobile stations (MSs) taking into account headroom size indicating transmission power additionally available for each of the MSs; and determining a transmission format of an MS selected to be preferentially allocated a slot as a result of the priority calculation, taking into account headroom size reported by the selected MS and a margin determined depending on a variation in channel state between the selected MS and a base station (BS).

System and method for scheduling uplink in a communication system

Provided is a wireless mobile communication system in which a mobile station reports a headroom value indicating the magnitude of currently used transmission power and additionally usable transmission power. An uplink scheduling method of a Base Transceiver Station (BTS) includes normalizing the headroom value according to a pre-set reference transmission format; determining a mean data rate of the mobile station; and determining a priority of the mobile station considering the normalized headroom value and the mean data rate.

Apparatus and method of determining uplink priority in wireless mobile communication system

A method and device for controlling a selection of the menu displayed on a screen of a TV or PC using a pointing device. The method includes the steps of apportioning the screen for a plurality of menu fields each to include a specified area surrounding a respective menu item, and enabling the menu item included in one of the menu fields indicated by the pointer of the pointing device to be selected.
