Patent ID: 8923196

Claim:
A method performed in user equipment (UE) of a wireless communications network, the method comprising: detecting, by the UE, a resource collision between uplink channels for acknowledgement/negative acknowledgement (ACK/NACK) signaling of a first component carrier and ACK/NACK signaling of a second component carrier; generating a single indicator including aggregating ACK/NACK signals from each of the first component carrier and the second component carrier into a single signal, wherein aggregating ACK/NACK signals from each of the first component carrier and the second component carrier into a single signal comprises at least taking the logical AND of an ACK/NACK bit of the first component carrier and an ACK/NACK bit of the second component carrier; and transmitting, to a base station, the single indicator representative of the ACK/NACK signaling of the first component carrier and the ACK/NACK signaling of the second component carrier.
