  • Publication number: 20230362709
    Abstract: A method of deriving packet filter component of derived QoS rule and evaluating of packet when there are multiple C-TAGs and/or S-TAGs in Ethernet frame header is proposed. In one novel aspect, for a derived QoS rule, when a DL packet carries multiple C-TAGs or S-TAGs, the UE derives packet filter component of the QoS rule derived from the outermost C-TAG and/or the outermost S-TAG of the DL packet. In another novel aspect, when evaluating a data packet carrying multiple C-TAGs or S-TAGs, the UE/NW evaluates the outermost C-TAG and/or the outermost S-TAG of the data packet, the UE/NW then send the data packet on the corresponding QoS rule of the matched packet filter.

  • Patent number: 11043161
    Abstract: The invention discloses a control circuit for controlling a panel. The panel includes a plurality of light-emitting elements arranged as an array. Each row of light-emitting elements among the plurality of light-emitting elements are coupled to each other via one of a plurality of scan lines. The control circuit includes a current source, an emission switch, a plurality of scan switches and a level adjustment circuit. The current source is coupled to a column of light-emitting elements among the plurality of light-emitting elements. The emission switch is coupled to the current source and the column of light-emitting elements. Each of the plurality of scan switches is coupled to one of the column of light-emitting elements via one of the plurality of scan lines. The level adjustment circuit is coupled between the plurality of scan lines and the current source.
