To facilitate practical implementation of a Dynamic Decode-&-Forward (DDF) for type-2 User Equipment (UE) relay defined in 3GPP which is being considered for next-generation cellular standards (e.g., LTE-Advanced), the authors propose "Modified Dynamic DF (M-DDF)" to realize fast jump-in relaying and decoding scheme for cooperative transmission. More specifically, subframe based sequential decoding is employed to yield some combinations of energy/information/mixed combining, in conjunction with the random codeset for encoding and re-encoding at source and multiple UE relays, depending on their channel conditions.
