    • A method for making a mobile station receive a communication service is provided to allow the mobile station to receive the communication service from at least two base stations cooperatively, thereby improving a communication performance of the mobile station. Signals are received from at least two base stations(301). Signal strengths of the base stations are measured. An expected transmission rate of a mobile station is estimated. If the expected transmission rate is less than a predetermined standard, at least two base stations are selected according to a signal strength order(307). Information of the selected base stations and channel state information are transmitted to a base station, which is providing or receiving a communication service to the mobile station(309). Powers and resources are allocated from the selected base stations(311). A signal transmission and reception process is performed between the mobile station and the selected base stations by using the allocated powers and resources(313).
