The on-going commercialization of LTE networks has precipitated increasing interest in the deployment of eMBMS. As the industry is considering the first deployments of eMBMS it is important to enhance the performance and usability of its core features. After development of the initial MBMS specifications, SA4 has focused its subsequent work on adding new features to the service. While application layer FEC usage in support of download and streaming delivery methods have been specified since Rel-6, those mechanisms have not been updated to reflect performance improvement developments in more recent years. Examples of ongoing FEC enhancement efforts are the latest activities in IETF's RMT and FECFRAME working groups. Such FEC improvements can also provide more efficient support of MBMS use cases. The objective of this TR is to document the progress of the work item to investigate and evaluate proposed FEC technologies and, if appropriate, adopt one which provides the most significant enhancement to the performance of the MBMS system over the Rel-6 application layer FEC in MBMS. Aspects of system performance, which would provide benefit to the system, include, but are not limited to

• Improving the bandwidth efficiency of streaming and download services delivery over MBMS
• Improving the reliability of streaming and download services delivery over MBMS, e.g. by increasing the amount of tolerable lost packets for a given FEC overhead
• Reducing the required computational and memory resources for decoding in UEs
• Addressing backward compatibility issues by considering deployments of pre-Rel-11 MBMS FEC

The evaluation and selection process for the proposed improvements is documented in this TR. This Technical report contains the following attachments:

• Attachment-1-Tools.zip: This attachment contains relevant tools for the purpose of setting up the evaluation framework.
• Attachment-2-Benchmark-Codes.xls: This attachment contains all relevant results for the benchmark codes
• Attachment-3-Submission.zip: This attachment contains all submitted code overhead and device-evaluation results of the candidates
• Attachment-4-Verification.zip: This attachment contains all verification results for device-based evaluation.
• Attachment-5-6330.zip: This attachment contains the proposed application of 6330 as MBMS application layer FEC as provided by the proponent.
• Attachment-6-RS+LDPC.zip: This attachment contains the proposed application of RS+LDPC as MBMS application layer FEC as provided by the proponent.

The present document documents the progress of the work item to investigate and evaluate proposed FEC technologies and adopt one which provides the most significant enhancement to the performance of the MBMS system over the Release 6 application layer FEC in MBMS.
