UPLINK CONTROL CHANNEL RESOURCE COLLISION AVOIDANCE IN CARRIER AGGREGATION SYSTEMS

摘要

Systems, apparatuses, and methods of a wireless communications network include identifying a first downlink control channel. The possibility of an acknowledgement / negative acknowledgement (ACK/NACK) resource collision on a first uplink control channel is determined for a first component carrier and a second uplink control channel for a second carrier component. A second downlink control channel can be identified to avoid the ACK/NACK resource collision.
