A feasible design of ultra-dense Small cell network involves an effective solution to the interference coordination especially in cell edge. In this paper, we propose a channel state and interference aware power allocation scheme (PAG) as an enhanced solution to improve the system performance, especially for the cell-edge users. Cournot model in Non-cooperative game is employed for power adjustment...
Call admission control (CAC) is a key factor in quality of service (QoS) provisioning for different services. In this paper, a Quasi-birth-and-death (QBD) process model is developed for the purpose of evaluating the CAC schemes of the cellular systems, where exist several types of traffics with different arrival rates. The CAC controller seeks to optimize the throughput and minimize the blocking probability...
On the reverse link of CDMA systems, two options are possible for resource allocation: rate control (RC) and centralized scheduling (CS). The rate control algorithm can be further divided into Common Rate Control (CRC) and Dedicated Rate Control (DRC). In CRC, each mobile station (MS) independently determines its reverse link rate using the system interference level information broadcasted by a base...
This paper proposes a novel power control algorithm on the reverse link (RL) of the CDMA system, which takes the interference interaction among mobile stations (MSs) into consideration. The proposed algorithm is based on power control commands with the assumption that each MS can collect power control information for other MSs in the same cell as references to determine its own transmit power. The...
