Abstract: to signal critical updates to bss parameters of reported affiliated aps, a reporting ap of the same ap mld includes a mld bss parameters change count in the ml element of its ml beacon frames. the count is incremented at each new bss parameter critical update announced or reported by the reported affiliated aps over time. a non-ap station of a non-ap mld in ml power save mode receives such beacon frame and then directly accesses this information without parsing the complex reduced neighbor report information element. the rnr ie can thus be omitted to save bandwidth. next, the non-ap station requests the reporting ap for the missing updated bss parameters of the reported aps, without waking up the reported non-ap stations of the non-ap mld. the bss parameters for these reported non-ap stations can then be updated with low complexity.

Abstract: a light emitting device includes an organic light emitting element arranged above a substrate and including an anode, an organic functional layer including an organic light emitting layer, and a cathode, a capacitive element including an upper electrode arranged between the substrate and the organic light emitting element so as to reflect light entering from the organic functional layer via the anode, a dielectric layer arranged between the substrate and the upper electrode, and a lower electrode arranged between the substrate and the dielectric layer, and an insulating layer arranged between the capacitive element and the organic light emitting element. the upper electrode is electrically insulated from the anode. a distance between the upper electrode and the organic light emitting layer is adjusted so as to improve efficiency of light extraction from the organic light emitting layer.
