Optimizing the locations of the RRHs with no fronthaul constraint between the control unit (CU) and its remote radio heads (RRHs).
We are using a traffic distribution to represent the traffic in the network, where hotspots are shown in yellow. We have 10 RRHs in each cell controlled by a CU. Each CU is equipped with 64 antennas while each RRH is equipped with 8 antennas. The RRHs in each cell jointly serve their users. We are using K = 8 users being served on the same access channel. For these results, we are using zero-forcing beamforming on both the access channel and the fronthaul, which are separated through frequency division.Â
Optimizing the locations of the RRHs under a fronthaul constraint using a zero-forcing beamforming on both the access channel and the fronthaul with 3 resource blocks (RBs) allocated for the access channel and 22 RBs for the fronthaul. Also, K = 8 users are being jointly served on the same access channel by the RRHs in each disjoint cell. We have 10 RRHs per cell, each equipped with 8 antennas. As for the CU in each cell, it is equipped with 64 antennas. For our algorithm, we are starting with a feasible point, so as a starting point the RRHs are being placed in an area close to the CU.
