Methods and apparatus for scheduling mobile stations to download data andor to control the rate of downloading to an MS from a base station as a function of downlink channel condition information are described. When using a thin film made of such an organic material in a low-molecular-weight organic EL element and a polymer organic EL element, EL element characteristics such as low drive voltage and high luminous efficiency can be improved. The signal maps may be used to generate models of the indoor space. A self-aligned opening is formed by removing a portion of an insulation layer adjacent the at least one damascene conductive structure. Additionally, the toys are programmable by a remote control device. To this end an output signal is fed to a correction device, that is provided to correct the signals with an estimated time error and to produce M signals.
