    The principle of interface protocol architecture is the logical mutual-independence between

    layers and planes. Protocol layers of a specified protocol version, or even all layers in a

    plane can be modified if required in the future.

    MAC: Transport Formation Selection(2)

    Transport Format (TF) defines Transport Block Set (Transport Block Size,

    Transport Block Set Size) Transport Format Set (TFS): Possible TF combinations of a transport channel.

    MAC will chose a TF during every TTI

    Transport Format Combination (TFC): Determined TF combination in each TTI,

    each transport channel

    Transport Format Combination Set (TFCS): define all possible TFC combination

    method. Thus MAC can process dynamic transport rate control in different

    transport channels
