A scheduling policy based on different users´ requirements in base station cooperation systems

The study of the scheduling is one of the key issues in the downlink of the base station cooperation communication. Traditional scheduling policies for users focus on the edge transmission rate and the average transmission rate of cells unilaterally, which leads to irrational allocation of resources. This paper proposes a scheduling policy based on different QoS (Quality of Service) Requirement of users aiming at maximizing the capacity (namely the number of users who are served by a system) of the system, which can allocate resources reasonably according to the users´ required rate and allowed delay while taking the enhancement of the throughput of cells into account. Simulation results show that compared with traditional users scheduling policies, the new policy can improve the capacity of cells greatly at the cost of a small reduction of throughput.
