Abstract
We derive a new achievable rate region for the user cooperation channel, which exceeds the best known result for this channel [3]. Since the user cooperation channel includes many other known channels as a special case, the new rate region provides improved achievable rates for these cases. The most notable example is that of the Gaussian relay channel, for which we present a new closed form inner bound (Corollary 2) higher than the only known result (Theorem 5 in Cover and El Gamal) for many channel conditions.
