A chamber may have an outer barrier and a tensile member. These systems and methods provide high power factor without wasting energy. In the manner according to the present invention, a still function can be quickly processed and a still frame can be displayed at the exact time required. The base station receives channel quality information report CFN from a first mobile station one or more times, but less than L times; and, prior to reception of the Lth repetition of CFN, successfully decodes CFN to form a first decoded report. The method is variously performed according to a proxy mode or a non-proxy mode, and further according to which SLP has a positioning procedure. In another aspect, the invention provides a dynamic scheduling method.
