In this study, the authors address the downlink resource (subchannels and power) allocation problem for device-to-device communication with wireless power transfer technique in a cellular network to improve the energy efficiency (EE). The considered problem is formulated as maximising the weighted EE and is solved by leveraging a game-theoretic learning approach. Specifically, they first prove that...
A hierarchy precoding approach is proposed in this study for multi-cell multiuser systems with any number of base stations and that of users, which is suitable for any number of data streams. The key feature of this approach is aligning the inter-user interferences within the same cell to the room spanned by the inter-cell interferences, by which both the inter-cell and inter-user interferences are...
In this paper, a semi-distributed dynamic resource allocation scheme is developed for the downlink of multi-cell systems with full spectral reuse. Firstly, each base station (BS) schedules one user from all the users in its own cell based on maximal SINR criterion, and then reports the channel and interference information of its scheduled user to a central resource manager (CRM). Finally, the CRM...
