This paper proposes a simple hybrid decode- compress- and-forward and compress-and-forward (DCF&CF) relay scheme for the coordinated multipoint (CoMP) uplink transmission. In particular, we consider a scenario that two mobile users (MUs) transmit signal to two access points (APs), which are linked to the central unit (CU) via lossless capacity-limited fronthaul. To characterize the achievable rate region of the considered system, a rate maximization problem is formulated and solved by exploiting the monotonicity and convexity of its objective function. Furthermore, maximum sum rate of the two MUs is obtained according to the maximized rate region boundary. Finally the analysis is validated by numerical results.
