Detecting the number of transmit antennas in a base station

A communications device comprising memory and at least one processor coupled to the memory, wherein the at least one processor is configured to execute instructions stored on the memory such that when executed, cause the communications device to:

• select a scrambling sequence from a plurality of scrambling sequences dependent upon a number of transmit antennas, wherein a first scrambling sequence is selected when the number of transmit antennas is less than 4 and a second scrambling sequence is selected when the number of transmit antennas is 4;
• and
• scramble a plurality of bits of data using the selected scrambling sequence.

A method comprising:

• selecting, by a communications device in a wireless communication network, a scrambling sequence from a plurality of scrambling sequences dependent upon a number of transmit antennas at a transmitter, wherein a scrambling sequence of (0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1) is selected when the number of transmit antennas is 4;
• and
• scrambling, by the communications device, a plurality of bits of data using the selected scrambling sequence.
