Abstract:
1. A baseband processing method in a transmitter for handling discontinuous transmission indication bits (DTX bits) when transmitting using a 16 QAM signal point constellation mapped on an I-branch and a Q-branch wherein, for a quadruple of bits comprising two I-branch bits, i 1 and i 2 , and two Q-branch bits q 1 and q 2 , the method comprising: (1) performing no transmissions on both I and Q branches when both I-branch bits i (2) if both I-branch bits i (3) if both Q-branch bits q (4) if there are three DTX bits and a non-DTX bit in the quadruple of bits, replacing the three DTX bits with the non-DTX bit; (5) if there is a single DTX-bit in the I-branch bits, replacing the I-branch DTX-bit with the non-DTX bit of the I-branch; (6) if there is a single DTX-bit in the Q-branch bits, replacing the Q-branch DTX-bit with the non-DTX bit of the Q-branch.
