摘要： 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.

摘要： Disclosed is an apparatus and method for transmitting/receiving data using a low-density parity check (LDPC) coding scheme in a communication system. The method includes generating a multi-user data packet containing data to be transmitted to a plurality of users, encoding the multi-user data packet as a BCC and an LDPC code, and transmitting the encoded multi-user data packet to the plurality of users.

摘要： A method and apparatus of accessing a channel in a wireless local area network is provided. A destination station receives a request to send (RTS) frame to allocate a network allocation vector from a source station over a first bandwidth and transmits a clear to send (CTS) frame over a second bandwidth to the source station in response to the RTS frame. The second bandwidth is dynamically determined when a first parameter has a predetermined value.
