With the increasing demand for higher performance wireless local area networks (WLANs), channel bonding was first proposed in the IEEE 802.11n protocol to offer a higher data rate by combining two 20 MHz channels into one 40 MHz channel. Although much has been understood about channel bonding management, hardly any of these innovations have made it into today's IEEE 802.11 WLANs in a distributed manner...
This paper studies user-specific clustering for a downlink cloud radio access network (C-RAN), where a central unit (CU), connected to all base stations (BSs) via limited-capacity backhaul links, coordinates the BSs to form cooperative clusters for every user. By taking into account the training overhead for channel estimation in C-RAN, we design the clustering scheme aimed at maximizing the average...
Coordinated multi-point (CoMP) transmission can significantly improve the spectral efficiency of cellular networks. To reduce the training overhead and the complexity for implementing CoMP, an effective way is to divide base stations (BSs) into cooperative clusters. However, with disjointed clusters, the cluster-edge users suffer from inter-cluster interference. In this paper, a scheme is designed...
