Abstract:
1. A scheduling method for a femtocell base station in a cellular communication system including the femtocell base station and at least one mobile station connected to the femtocell base station, said mobile station running a plurality of applications, the method as implemented in said femtocell base station comprising the steps of: receiving data packets at said femtocell base station in said cellular communication system; differentiating each of said received data packets based on its destination address and an associated application among said plurality of applications; for each destination address, placing packets of each application in separate buffers, wherein applications are scheduled and one or more of the following system resources are allocated amongst scheduled applications: femtocell base station transmit power, transmission code space, antennas when said femtocell base station is equipped with multiple antennas, and available bandwidth, such that the following are jointly maximized using multiple objective optimization: goals of satisfaction of Quality of Service (QoS) requirements of each active application served by said femtocell base station, user and application priority level scaled fairness of service, and sum throughput of said femtocell base station; transmitting head-of-line packets from each scheduled applications' buffer over a next transmission period; and updating QoS requirements, current QoS satisfaction/dissatisfaction levels, observed and average channel qualities for a user, and average observed data rates for each application in time for a next scheduling decision.
