Joint Rate and Energy Coverage of User-Centric SWIPT-Enabled Millimeter Wave Networks

Abstract

In this paper, we consider a user-centric simultaneous wireless information and power transfer (SWIPT) mmWave system, where a time switching protocol is employed at users to support both energy harvesting and information decoding. To enable user-centric BS cooperation, dynamic BS clustering is used to adapt the user’s serving cluster to the channel condition. For this setup, we characterize the joint rate and energy (JRE) coverage, namely, the probability that the user can both harvest sufficient energy in a given time slot and receive the required minimum data from a given serving cluster. The analysis is challenging because of the random serving clusters as well as the correlation between the amount of harvested energy and the information rate. All analytical results are validated by Monte-Carlo simulations. Our results reveal that the proposed analytical models are accurate and efficient in the design and deployment of user-centric-SWIPT mmWave systems.
