Modified Dynamic DF for Type-2 UE Relays

A Dynamic Decode-&-Forward (DDF) is redesigned to meet the crucial requirements for type-2 User Equipment (UE) relays which are being considered for next-generation cellular standards (e.g., LTE-Advanced). Toward this, the proposed Modified DDF (M-DDF) realizes a fast jump-in relaying and sequential decoding where a sub-frame decoding is employed to yield a combination of energy/information/mixed combining, in conjunction with the random code-set for encoding and re-encoding at source and multiple UE relays, depending on their channel conditions. These additional features existing in the M-DDF circumvent the need of exchanging control messages between multiple relays and end user near cell boundary, which is not allowed for type-2 UE relays.
