Characterizing user to Remote Radio Head (RRH) association strategies in Cloud Radio Access Networks (C-RANs) is critical for performance optimization. In this letter, the single nearest and N - nearest RRH association strategies are presented and the corresponding impact on the ergodic capacity of CRANs is analyzed, where RRHs are distributed according to a stationary point process. Closed-form expressions for the ergodic capacity of the proposed RRH association strategies are derived. Simulation results demonstrate that the derived uplink closed form capacity expressions are accurate.
