Abstract:
1. A method for determining a resource index in a wireless communication system, comprising: mapping, by a user equipment (UE) having multiple logical antennas, at least two control channel elements (CCEs) for the UE to at least two demodulation reference signal (DRS) indices the UE according to a predetermined mapping rule; allocating, by the UE, one of determined demodulation reference signal (DRS) index for each logical antenna; transmitting, by the UE, the allocated demodulation reference signal (DRS) index from each logical antenna; mapping, by the UE, the at least two CCEs for the UE to at least two ACK/NACK indices for the UE according to a predetermined mapping rule; and allocating, by the UE, at least one of determined ACK/NACK indices for each logical antenna; transmitting, by the UE, the at least one allocated ACK/NACK index from each logical antenna.
