A method for color registration includes determining if color registration is necessary, and if color registration is necessary, rotating an image forming medium and setting an optimum luminance of a registration sensor with respect to a rotating surface of the image forming medium, confirming an area with an undesirable surface condition on the image forming medium using luminance detected with respect to the rotating surface of the image forming medium during the setting of the optimum luminance, forming a preset mark for color registration adjustment excluding the area confirmed to have an undesirable surface condition, and carrying out color registration adjustment using the optimum luminance set with respect to the formed mark.

A method for reducing power consumption in a wireless communication system includes: generating a descramble initial value by using at least some bits of identification information of an STA, which is known to an AP or base station and the STA; generating a first descramble sequence by using the generated descramble initial value and comparing at least some bits of the generated first descramble sequence with at least some bits of a service field of a currently-received signal; as the comparison result, when it is determined that the destination of the currently-received signal is not set to the STA, stopping the signal reception; and as the comparison result, when it is determined that the destination of the currently-received signal is set to the STA, generating a second descramble sequence by using the descramble initial value and descrambling the currently-received signal.

A method for transmitting a data block in a wireless communication system and a transmitter are provided. The transmitter transmits the data block to a receiver and generates a retransmission block for the retransmission of the data block if it is determined that the transmission fails. The transmitter determines whether the channel access is performed according to a transmit time of the retransmission block.
