Bidirectional communication method in cellular mobile wireless communication systems where multiple base stations are used for downlink and uplink connections

摘要

The present invention relates to a method for handling a bidirectional connection involving a mobile station in a cellular mobile wireless communication system having substantially different sized adjacent cells, the mobile station being capable of varying the strength of wireless signals received from a base station for cells of different sizes. The signal strength received by the base station for cells of different sizes from the mobile station is estimated, and a determination of which base station (s) serves as the uplink channel of the bidirectional connection is estimated Based on the uplink parameters including the strength, the signal strength in the base station serving as the uplink channel is used to control the output power of the mobile station, and which base station (s) serve as the downlink channel of the bidirectional connection. The determination is based on the addition of wireless signals received at the mobile station from the base station. It is done based on the downlink parameter including the predetermined strength.
