摘要：
A bit scrambling method and apparatus for packet transmission/reception in a wireless communication system are provided. A transmitter performs bit scrambling before CRC attachment and a receiver performs bit descrambling after a CRC check. This enables termination of iterative decoding at a turbo decoder according to the CRC check. Hence, power consumption is reduced and throughput is increased at a receiver.
