Description: Origin can be traced back to “Capacity theorems for the relay channel” by T Cover and AE Gamal.
Found the theoretical upper limit of the achievable data rate of a channel with a helper node called “relay”.
Relay has found its utility in modern communication systems
Relays will manifest themselves as a reality in the IEEE 802.16j standard.
This is still under evolution.
Motivation was to study the transformation of the relay concepts and research results in this area into a practical standard implemented by a system
