Ack/nack transmission for multi-carrier operation

An apparatus for wireless communication, comprising:

• means for receiving a data transmission on at least one component carrier (CC) in a plurality of CCs configured for a user equipment (UE);
• means for determining acknowledgement/negative acknowledgement (ACK/NACK) information for the data transmission;
• means for determining a number of resource elements for sending the ACK/NACK information based on the plurality of CCs configured for the UE;
• and
• means for sending the ACK/NACK information based on the determined number of resource elements.

An apparatus for wireless communication, comprising:

• at least one processor configured to:
• receive a data transmission on at least one component carrier (CC) in a plurality of CCs configured for a user equipment (UE),
• determine acknowledgement/negative acknowledgement (ACK/NACK) information for the data transmission,
• determine a number of resource elements for sending the ACK/NACK information based on the plurality of CCs configured for the UE, and
• send the ACK/NACK information based on the determined number of resource elements;
• and
• a memory coupled to the at least one processor.

A non-transitory computer-readable medium having program code recorded thereon, the program code comprising:

• code for causing at least one processor to receive a data transmission on at least one component carrier (CC) in a plurality of CCs configured for a user equipment (UE),
• code for causing the at least one processor to determine acknowledgement/negative acknowledgement (ACK/NACK) information for the data transmission,
• code for causing the at least one processor to determine a number of resource elements for sending the ACK/NACK information based on the plurality of CCs configured for the UE, and
• code for causing the at least one processor to send the ACK/NACK information based on the determined number of resource elements.
