There are relation one to one in CCE sequence number and ACK/NAK resource sequence number, and UE determines unique ACK/NAK resource according to the CCE sequence number, for example the CCE of first CCE sequence number is defined as the resource of the ACK/NAK of first transmitting antenna.
The resource sequence number of supposing the ACK/NAK of this first transmitting antenna herein is n1.
For example, UE determines that the ACK/NAK resource (its ACK/NAK resource sequence number is nk) that k transmitting antenna use and the functional relation of first transmitting antenna ACK/NAK resource are:
nk＝n1+k-1。
Having two transmitting antennas with UE is example, the sequence number of the ACK/NAK resource that first transmitting antenna uses is during as n1, the ACK/NAK resource (its ACK/NAK resource sequence number is n2) that second transmitting antenna uses is back one of first transmitting antenna ACK/NAK resource, just n2=n1+ 1.
