Forward Error Correction (FEC) for Mission Critical Services
The objective of the present document is to document the progress of the study item to investigate and recommend an FEC scheme for MCVideo that can be utilized equally by the two FEC procedures specified in 3GPP TS 23.280 [7]. The study will also consider whether the same or a similar scheme may be utilized for other MC services over MBMS (e.g. MCData – file download, or MCPTT group communications). The use of FEC is within the context of the MC services common functional architecture as explained in subclause 5.2.6 of 3GPP TS 23.280 [7]. This study item will build upon the existing stage-2 application architecture for MC services as defined in 3GPP TS 23.280 [7], 3GPP TS 23.281 [8], 3GPP TS 23.282 [9], and 3GPP TS 23.379 [10].
