    Abstract: Disclosed are a dimming method, a dimming device and a computer storage medium. The method comprises: segmenting, on a Media Access Control (MAC) layer, a MAC Service Data Unit (MSDU) into multiple sub-MSDUs of the same length; encapsulating the sub-MSDUs after the segmentation into separate MAC Protocol Data Units (MPDUs), and separately generating a Compensation Frame (CF) for each MPDU according to a target brightness value of a light source; and aggregating the MPDUs and the CFs into a Physical Layer Service Data Unit (PSDU) of a Physical Layer Protocol Data Unit (PPDU) and transmitting the PPDU.

    Abstract: Provided are a light dimming method for alleviating inter-frame flicker and dimming device. The light dimming method includes that: an average luminance value Avgdata when a sender sends physical frames is calculated; whether inter-frame flicker is generated when the sender sends data or not is judged according to a ratio of Avgdata to an average luminance value Avglight in an illumination state; and if the inter-frame flicker is generated when the sender sends the data, the sender inserts a dimming frame in an idle pattern, wherein the dimming frame is used for compensating for a luminance difference between Avgdata and Avglight. A value of a duty cycle of the physical frame sent to regulate the luminance of the light source in the idle pattern of the sender is within a certain range, and is not required to be accurately equal to a duty cycle of a line coding method adopted for a physical layer.

    Abstract: A method and apparatus for implementing dimming are disclosed. The method includes: at an MAC layer, dividing an MSDU into two or more sub-MSDUs with a same length; encapsulating each sub-MSDU obtained after dividing into a separate MPDU, and generating a compensation frame for each MPDU; and aggregating the MPDUs and the compensation frames with the same addresses into a PSDU part of a PPDU and transmitting a physical frame.
