A Low-Complexity Cache-Aided Multi-antenna Content Delivery Scheme

16 May 2019 Zhao Junlin Amiri Mohammad Mohammadi Gündüz Deniz

We study downlink beamforming in a single-cell network with a multi-antenna base station (BS) serving cache-enabled users. For a given common rate of the files in the system, we first formulate the minimum transmit power with beamforming at the BS as a non-convex optimization problem... (read more)
