Base station cooperation in heterogeneous wireless networks (HetNets) is a promising approach to improve the network performance, but it also imposes a significant challenge on backhaul. On the other hand, caching at small base stations (SBSs) is considered as an efficient way to reduce backhaul load in HetNets. In this paper, we jointly consider SBS caching and cooperation in a downlink large-scale...
In this paper, we propose a network coding scheme for up-link wireless backhaul networks to increase the throughput while guaranteeing full diversity order. The key advance proposed is the employment of precoding complex field matrices for two user and two base station backhaul networks to achieve throughput of 1 symbol/channel use while guaranteeing full diversity order for this one-way two-hop communications...
