“…The data for each user is only transmitted by the serving BS, making this approach practical when backhaul capacity is limited [141], [142]. In the presence of perfect CSI, complete interference cancellation is possible by coordinated zeroforcing beamforming (ZFBF), but this also causes a loss in the [105] tilt in the uplink that maximizes the asymptotic SE under pilot contamination…”

“…The TXRU virtualization weight vectors need to be adapted dynamically to realize different elevation beamforming scenarios. Due to the lack of literature available on TXRU virtualization models, the optimization of the vertical and horizontal weight functions has not been a subject of theoretical works on elevation beamforming so far, with the only notable exceptions being [53], [65], [105]. This section made an attempt to bridge this gap between the 3GPP and academia by introducing different TXRU architectures and corresponding example weight functions that can be optimized in future works to realize desired elevation beamforming scenarios.…”
