Abstract  Abstract

Data is scrambled at a transmitter according to one of a number of predetermined scrambling sequences which are associated with a particular one of a number of predetermined transmit antenna diversity schemes (i.e. a specific number of transmit antenna ports). Received data is decoded using one or more of the known transmit antenna diversity schemes and the scrambled data is descrambled according to a corresponding descrambling sequence (related to the scrambling sequence). Based on the descrambled data the receiver determines which transmit antenna diversity scheme (i.e. the number of antenna ports) is used by the transmitter. In one specific embodiment CRC parity data is scrambled in the transmitter and the receiver descrambles the recovered CRC parity data according to a descrambling sequence computes CRC parity data from the received data and compares the descrambled CRC parity data to the newly computed CRC parity data.
