Abstract
In a first CDMA communication method, a CDMA radio wave signal is transmitted at a first place (a base station). A mobile unit receives the first CDMA radio wave signal and stores at least a portion of the data in the received signal and returns it to the base station by attaching the portion of the data to second data to be transmitted through spectrum spreading, wherein the data rate of the attached data is higher than the second data. The base station detects an upward line transmission quality from the received second CDMA radio wave signal from the mobile unit and detects a downward line transmission quality from the attached data forwarded by the mobile station. The base station outputs the downward line transmission quality when the upward line transmission quality is higher than a reference. When the downward line transmission quality is lower than a reference, the data is retransmitted from the base station and for a predetermined interval in this condition, transmission is stopped as transmission controlling. In a second CDMA communication method, the downward line transmission quality is measured in the mobile station and the data of downward line transmission quality is attached in place of the forwarded data and transmission controlling is similarly provided. Corresponding base and mobile stations are also disclosed.
