Abstract:
1. A method of receiving, by a base station (BS), control signals in a wireless communication system, the method comprising: receiving channel quality indicator (CQI) bits which are quadrature phase shift keying (QPSK) modulated and mapped to a plurality of data symbols in a slot; and receiving a control signal which is multiplexed with 1 and mapped to a second reference signal (RS) sequence if the control signal has a first value; or receiving a control signal which is multiplexed with −1 and mapped to a second RS sequence if the control signal has a second value; wherein a first RS sequence is mapped to a first RS symbol in the slot and the second RS sequence is mapped to a second RS symbol in the slot.
