In the determined set of the physical channel data bit sizes(SET2), in a state that a physical channel data bit size having an SF(Spreading Factor) 2 is regarded as having an SF 4, the number of corresponding physical channels is set double. The maximum physical channel data bit size that does not require any additional physical channel is selected.

Abstract: A handle unit of a window glass regulator in a vehicle is provided to easily separate the handle unit by pushing an escutcheon with a separation tool in repairing owing to adding a clip separation boss to the escutcheon. A handle unit of a window glass regulator includes a handle(100) combined with a regulator shaft lifting up and down a window glass outside a door trim, an ohm type clip(200) assembling the handle with the shaft, and an escutcheon(300) placed between the handle and the door trim. A central elongated hole(310) is formed in the middle of the escutcheon to move the escutcheon uni-directionally, and two bosses(320) are protruded on the escutcheon to push and separate both ends of the clip. A fitting sill is protruded and formed in a rear part of the escutcheon to prevent displacement of the handle. A tool insertion groove is formed in an outer periphery of the escutcheon, and a mark is engraved in the handle to place the tool insertion groove.
