Enhanced multicast broadcast multimedia service in enhanced component carriers over variable transmission bandwidth

An apparatus for wireless communication, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
• map one or more multicast broadcast multi-media service (MBMS) transport blocks to a plurality of carriers over a system bandwidth comprising the plurality of carriers, wherein the one or more MBMS transport blocks comprise a single MBMS transport block for the system bandwidth;
• perform a clear channel assessment (CCA) on each carrier of the plurality of carriers;
• select a portion of the one or more MBMS transport blocks to transmit based at least in part on a result of the CCA for the plurality of carriers;
• puncture the single MBMS transport block in a guard region of a first carrier for which the result of the CCA was a successful CCA and a second carrier for which the result of the CCA was a failed CCA, wherein the first carrier is adjacent to the second carrier;
• and
• transmit, according to the mapping, the selected portion of the one or more MBMS transport blocks over one or more of the plurality of carriers for which the result of the CCA was a successful CCA.

• puncture the single MBMS transport block in a guard region of a first carrier for which the result of the CCA was a successful CCA and a second carrier for which the result of the CCA was a failed CCA, wherein the first carrier is adjacent to the second carrier;
• and
• transmit the selected portion of the one or more MBMS transport blocks according to the mapping over one or more of the plurality of carriers for which the result of the CCA was a successful CCA.
