An Users Scheduling Policy Based on Different Requirements in the Downlink of Base Station Cooperation Systems

The scheduling of cooperative users is one of the key issues in the base station cooperation communication. Traditional scheduling methods for users focus on the edge transmission rate and the average transmission rate of cells unilaterally, resulting in irrational allocation of resources. This paper proposed a new scheduling policy based on different QoS( Quality of Service ) of users aiming at maximizing the capacity of cells, 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.
