enhancing the primary content using the secondary content.

2. The method of claim 1 , wherein both of the first component carrier and the at least one second component carrier carry the service via broadcast.

3. The method of claim 1 , further comprising computing an error metric with respect to the primary content.

4. The method of claim 3 , further comprising requesting a switch to a unicast delivery of the service when the computed error metric is at or below a threshold value, before the service reaches an end of session.

5. The method of claim 3 , further comprising requesting a retransmission of at least one portion of the primary content when the computed error metric is at or below a threshold value, before the service reaches an end of session.

6. The method of claim 1 , further comprising:

receiving second configuration information via a Multicast Control Channel (MCCH) carried by at least one of the first component carrier or the at least one second component carrier; and

updating the configuration information based on the second configuration information received via the MCCH.

7. The method of claim 1 , further comprising:

receiving second configuration information via a System Information Block (SIB) carried by at least one of the first component carrier or the at least one second component carrier; and

updating the configuration information based on the second configuration information received via the SIB.

8. The method of claim 7 , further comprising:

receiving third configuration information via a Multicast Control Channel (MCCH) carried by at least one of the first component carrier or the at least one second component carrier; and

updating the second configuration information received via the SIB based on the third configuration information received via the MCCH.

9. The method of claim 1 , wherein the service comprises an enhanced Multimedia Broadcast Multicast Service (eMBMS) service.

10. An apparatus for wireless communication, comprising:

a memory configured to store data; and

at least one processor coupled to the memory, wherein the at least one processor is configured to:

monitor a first component carrier and at least one second component carrier of a plurality of aggregated component carriers for a service and configuration information associated with the service;

receive the service concurrently via the first component carrier and the at least one second component carrier, wherein at least one of the first component carrier or the at least one second component carrier carries the service via broadcast or unicast, and wherein to receive the service concurrently via the first component carrier and the at least one second component carrier, the at least one processor is further configured to receive primary content via broadcast and secondary content via unicast; and

enhance the primary content using the secondary content.

11. The apparatus of claim 10 , wherein both of the first component carrier and the at least one second component carrier carry the service via broadcast.

12. The apparatus of claim 10 , wherein the at least one processor is further configured to compute an error metric with respect to the primary content.

13. The apparatus of claim 12 , wherein the at least one processor is further configured to request a switch to a unicast delivery of the service when the computed error metric is at or below a threshold value, before the service reaches an end of session.

14. The apparatus of claim 12 , wherein the at least one processor is further configured to request a retransmission of at least one portion of the primary content when the computed error metric is at or below a threshold value, before the service reaches an end of session.

15. The apparatus of claim 10 , wherein the at least one processor is further configured to:

receive second configuration information via a Multicast Control Channel (MCCH) carried by at least one of the first component carrier or the at least one second component carrier; and

update the configuration information based on the second configuration information received via the MCCH.

16. The apparatus of claim 10 , wherein the at least one processor is further configured to:

receive second configuration information via a System Information Block (SIB) carried by at least one of the first component carrier or the at least one second component carrier; and

update the configuration information based on the second configuration information received via the SIB.

17. The apparatus of claim 16 , wherein the at least one processor is further configured to:

receive third configuration information via a Multicast Control Channel (MCCH) carried by at least one of the first component carrier or the at least one second component carrier; and

update the second configuration information received via the SIB based on the third configuration information received via the MCCH.

18. The apparatus of claim 10 , wherein the service comprises an enhanced Multimedia Broadcast Multicast Service (eMBMS) service.

19. An apparatus for wireless communication, comprising:

means for monitoring a first component carrier and at least one second component carrier of a plurality of aggregated component carriers for a service and configuration information associated with the service;

means for receiving the service concurrently via the first component carrier and the at least one second component carrier, wherein at least one of the first component carrier or the at least one second component carrier carries the service via broadcast or unicast, and wherein primary content is received via broadcast and secondary content is received via unicast; and

means for enhancing the primary content using the secondary content.

20. The apparatus of claim 19 , wherein both of the first component carrier and the at least one second component carrier carry the service via broadcast.

21. A non-transitory computer-readable medium storing computer executable code, comprising code for:

monitoring a first component carrier and at least one second component carrier of a plurality of aggregated component carriers for a service and configuration information associated with the service;

receiving the service concurrently via the first component carrier and the at least one second component carrier, wherein at least one of the first component carrier or the at least one second component carrier carries the service via broadcast or unicast, and wherein to receive the service concurrently via the first component carrier and the at least one second component carrier, the code further causes the at least one processor to receive primary content via broadcast and secondary content via unicast; and

enhancing the primary content using the secondary content.
