We consider the downlink of a cellular wireless network where the base stations are equipped with multiple transmit antennas and operate in the same frequency band. Each base station serves one user per orthogonal frequency-division multiplexing (OFDM) sub-carrier by means of spatial precoding. Due to temporal scheduling, the active users change rapidly in time and consequently, intercell interference...
In this paper, we propose an adaptive sub-band exclusion (ASE) scheme as a means of intercell interference coordination (ICIC) technique to improve the performance of wireless cellular systems in a decentralized manner. Since ICIC is performed at each mobile station (MS), the proposed ASE scheme can be classified as a decentralized ICIC scheme. Compared to conventional centralized ICIC schemes, our...
3500 MHz fixed wireless access system is a point-to-multipoint (P-MP) wireless technology providing broadband services. In this paper, P-MP fixed cellular service network structure such as Local Multipoint Distribution (LMDS) service is proposed to share same network area and frequency band (3400-3600 MHz) with the fourth generation of mobile (IMT-Advanced) represented by mobile Worldwide Interoperability...
Cooperation between adjacent base stations (BSs) may reduce intercell interference in future cellular networks and enhance network capacity in this way. The potential of cooperation is evaluated in this paper based on measurements conducted at 5.2 GHz in a campus environment with four overlapping cells. For each individual link of the four BS and five terminal locations, a 10 times 16 antenna configuration...
