ABSTRACT:
A first mobile station generates an uplink error check code for a data frame for uplink transmission, and transmits the data frame and its associated uplink error check code to a cellular network. The network determines the quality of the received data frame and generates a downlink error check code for the received data frame. The received frame quality is determined as good or bad on the basis of a function of the received data or a parameter indicative of the quality of the received frame quality and the received data respectively. The data frame and the associated downlink error check code is transmitted to the second mobile station. The second mobile station decodes the received data frame and the associated downlink error check code and determines if the received data frame and the associated downlink error check code represents a good quality frame.
