Abstract: A method for transmitting channel quality information based on a differential scheme is disclosed. When channel quality information of a predetermined number of sub-bands selected by a receiver in a frequency selective channel is transmitted, total average channel information is transmitted. Channel information of the selected sub-bands is transmitted as sub-band differential information associated with average channel information. In this case, the sub-band differential information may be denoted by a specific value contained in a differential-value range including only positive (+) values. If at least two channel quality information is transmitted by a MIMO system, channel quality information of one channel is transmitted, then channel quality information of the other channel is transmitted as spatial differential information. In this case, the spatial differential information is denoted by a specific value contained in a differential-value range asymmetrical on the basis of “0”.

Abstract: A susceptor includes a first body including a plurality of first holes and a second body including a plurality of second holes. According to one arrangement, the second body is spaced from the first body to form a gap which allows a gas to pass from the second holes to the first holes. According to this or another arrangement, the first body is removably or rotatably coupled to the second body, or both. Rotation of the second body by a first amount or in a first direction brings at least one first hole in alignment with at least one second hole. And, rotation of the second body by a second amount or in a second direction causes a misalignment to occur between these holes.
