In order to ensure the quality of service of the communication link, the user equipment(UE) can connect with one or more micro base stations(MBSs) in the user-centric millimeter-wave distributed cell. How to select the optimal MBSs to communicate with UE is a problem according to the channel environment. Based on the limited feedback beamforming technique of random vector quantization (RVQ) codebook...
This correspondence studies the successive convex approximation for low complexity (SCALE) algorithm, which was proposed to address the weighted sum rate (WSR) maximized dynamic power spectrum management (DSM) problem for multiuser multicarrier systems. To this end, we first revisit the algorithm, and then present geometric interpretation and properties of the algorithm. A geometric programming (GP)...
