- Overview 

Existing cellular wireless networks are facing fundamental challenges due to the exponential demand of mobile data traffic, the need of higher data rates, user coverage, lowering latency, and minimizing signaling overhead. In order to address these challenges, future cellular networks will require adopting a multi-cell multi-tier cooperative architecture. However, in multi-cell cooperation, the user equipment (UE) needs to estimate the channel state information (CSI) and feed it back to the base station (BS) scheduler for adaptive resource management. This results in a significant increase of signaling overhead and feedback latency into the cooperative networks. These overhead and latency are the two key challenges to achieve gains in coordinated multi-point (CoMP) operation.
