Radio Resource Management for the Uplink of Hybrid Beamforming Systems (opens in new tab)

This paper studies radio resource management (RRM) for the uplink of a multi-channel cellular system with hybrid beamforming based on analog beamforming using predefined codebooks and zero-forcing digital beamforming. We first formulate a per-time slot joint RRM optimization problem, which includes beam selection, user selection, power allocation, modulation and coding scheme selection, and digital beamforming. A per-time slot formulation of the...
