System and method for controlling uplink traffic load in a cellular wireless mobile communication system

摘要

A method is provided for controlling an uplink traffic load in a wireless mobile communication system. A mobile station (MS) receives a reference signal from each of a base station (BS) of its home cell and a BS of a neighbor cell; calculates a power difference between the received reference signals to estimate a path loss value for each individual BS, and reports the estimated path loss value to the BS of the home cell. The BS of the home cell receives the estimated path loss value for each individual BS from the MS; and determines and allocates uplink traffic transmission power and a data rate to the MS taking the estimated path loss value into consideration. The MS transmits an uplink traffic signal taking into account the uplink traffic transmission power and the data rate allocated from the BS of the home cell.
