This paper provides a thorough analysis of the frequency resource allocation among multi-layers of the intra-RAT (Radio Access Technology) heterogeneous network. From the aspect of the spectrum utilization efficiency, the co-channel heterogeneous network provides higher system capacity, but its control channel coverage and quality is much worse than the orthogonal frequency allocation between macro...
The boom in user amount and voice traffic puts a huge pressure on the operators especially within populous countries, which forces them to enhance the voice capacity in the GSM evolution. The concept of Multi-User Reusing-One-Slot (MUROS) is promising to resolve this problem with negligible impact on handsets as well as to networks. In this paper, we compared the link-level and system-level performance...
Cooperative communication technology has been widely studied in recent years due to providing higher resource utilization and more reliable communication. In this work, we consider a downlink multi-user multi-input-multi-output (MU-MIMO) system with cooperative multi-cell transmission. Assuming that the channel state information are available at cell and user, we propose a simple user scheduling algorithm...
Relay communication network has been widely studied in recent years due to their ability to provide more reliable communication through enhanced diversity. In this work, we consider a downlink multiuser multi-input-multi-output (MU-MIMO) relay network under amplify and forward (AF) protocol. Coordinated relay system can provide the additional diversity gain due to adding the relay station (RS) compared...
