Downlink and Uplink Decoupling in Two-Tier Heterogeneous Networks with Multi-Antenna Base Stations
Mudasar Bacha, Yueping Wu, Bruno Clerckx
In order to improve the uplink performance of future cellular networks, the idea to decouple the downlink (DL) and uplink (UL) association has recently been shown to provide signif…
Rate Analysis of Two-Receiver MISO Broadcast Channel with Finite Rate Feedback: A Rate-Splitting Approach
Chenxi Hao, Yueping Wu, Bruno Clerckx
To enhance the multiplexing gain of two-receiver Multiple-Input-Single-Output Broadcast Channel with imperfect channel state information at the transmitter (CSIT), a class of Rate-…
User-Centric Interference Nulling in Downlink Multi-Antenna Heterogeneous Networks
Yueping Wu, Ying Cui, Bruno Clerckx
Heterogeneous networks (HetNets) have strong interference due to spectrum reuse. This affects the signal-to-interference ratio (SIR) of each user, and hence is one of the limiting…
Analysis and Optimization of Interference Nulling in Downlink Multi-Antenna HetNets with Offloading
Yueping Wu, Ying Cui, Bruno Clerckx
Heterogeneous networks (HetNets) with offloading is considered as an effective way to meet the high data rate demand of future wireless service. However, the offloaded users suffer…
